Because the tissue box often occurs when the tissue box is in use, when the front tissue at the paper outlet is pulled out, the rear tissue is not affected by the friction force when the front tissue is pulled out again and is partially brought out to the paper outlet, resulting in The rear tissue will still remain in the box, causing the user to dig out the subsequent tissue by hand before continuing to use it. During this process, the inside of the tissue box will be easily polluted due to human hands touching the inside of the tissue box.

In addition, after the front paper towels at the paper outlet are pulled out, the friction force caused by the front paper towels on the back paper towels is too large, or the paper towels are folded, resulting in simultaneous Multiple paper towels are produced, resulting in wastage of paper towels during use.

Based on this, some embodiments provide a transmission mechanism.

In addition, in some embodiments, as shown in FIG. 3 and FIG. 6 , the driving device 12 is a motor driving device, and the friction transmission device 11 includes: a friction member 111 and a transmission shaft 112 . Wherein, the friction member 111 is rotatable around a predetermined axis, and, as shown in FIG. 3 , the friction member 111 is arranged relative to the conveying surface 3 and forms a gap 200 with the conveying surface 3 . At the same time, the transmission shaft 112 is coaxially connected with the friction member 111 along the preset axis direction. In addition, as shown in FIG. 3 , the transmission shaft 112 is also connected to the driving device 12, so that the driving device 12 can drive the friction member 111 to rotate through the transmission shaft 112 after receiving the driving signal, thereby driving the soft towel 100 to move in a designated direction , if it is applied to a soft towel box, it can realize the automatic output of the soft towel 100.

As shown in FIG. 4 , the friction ring 11112 includes: an inner surface 111121 attached to the outer surface of the roller body 11111 , and an outer surface 111122 opposite to the inner surface 111121 , and the outer surface 111122 is a rough surface. Therefore, when the friction wheel 1111 is rotating, the outer surface 111122 of the friction ring 11112 can abut against the soft towel 100, and the transportation of the soft towel 100 can be realized by the friction force caused by the friction ring 11112 to the soft towel 100 when rotating.

In addition, as an alternative, in some other embodiments, as shown in FIG. 5 , the friction member 111 is a friction roller coaxially connected with the transmission shaft 112, so that the driving device 12 can pass through the transmission after receiving the driving signal. The shaft 112 drives the friction roller to rotate, and the soft towel 100 can be sent out from the output side 41 of the soft towel box by means of the friction force generated by the friction roller on the soft towel 100 when rotating.

Specifically, in some embodiments, as shown in FIG. 6 , the friction roller includes: a roller body 1112 and a friction ring 1113 . Wherein, the roller body 1112 is coaxially connected with the transmission shaft 112, and at the same time, the roller body 1112 has an outer roller surface around the preset axis direction, and the friction ring 1113 is sleeved on the outer roller surface of the roller body 1112, and along the roller body 1112 The length of the friction ring 1113 is extended in the axial direction. Of course, in practical applications, the length of the friction ring 1113 can also be increased or decreased according to specific needs. In this embodiment, the length of the friction ring 1113 is not specifically limited, and the friction ring 1113 Ring 1113 is used to rub against tissue 100 .

The inner surface 11131 is opposite to the outer surface 11132, and the outer surface 11132 is a rough surface. Therefore, when the friction roller 13 is rotating, the outer surface 11132 of the friction ring 1113 can contact the soft towel 100, and the friction ring 1113 can cause the friction force on the soft towel 100 when it rotates to realize the transportation of the soft towel 100.

In addition, it is worth noting that, in some embodiments, as shown in FIG. When the soft towel 100 is transported in cooperation with the conveying surface 3, the soft towel 100 can be completely abutted by the friction roller, so that the friction force of the friction roller on the soft towel 100 can be evenly distributed on the soft towel 100, so that when the soft towel 100 is discharged from the towel, After the side 41 is sent out, the flatness of the soft towel 100 can be ensured, and wrinkles can be avoided during the transportation of the soft towel 100 .

In addition, in some embodiments, as shown in FIG. 7 and FIG. 8, two friction transmission devices 11 may also be provided, which are respectively a first friction transmission device 11a and a second friction transmission device 11b, and the first friction transmission device The device 11a and the second friction transmission device 11b are arranged opposite to each other and parallel to each other. A gap 200 for conveying soft towels is formed between the first friction transmission device 11a and the second friction transmission device 11b. The first friction transmission device 11a and the second friction transmission device 11b are all used for rubbing against the soft towel 100 .

Next, as shown in Figure 7 and Figure 8, the driving device 12 is connected with the first friction transmission device 11a and/or the second friction transmission device 11b, and the driving device 12 is used to drive the first friction transmission device 11b after receiving the driving signal The transfer device 11a and/or the second friction transfer device 11b, so that the tissue 100 can be transferred by the first friction transfer device 11a and/or the second friction transfer device 11b. It is not difficult to see from this that, by driving the first friction transmission device 11a and/or the second friction transmission device 11b through the driving device 12, the automatic delivery of the soft towel 100 can also be realized, and the soft towel 100 can also be avoided from human interference.

It should be noted that, in some embodiments, the driving knob 133 is only set on the first frame body 131 for illustration. However, in practical application, the driving knob 133 may also be set on the second frame body 132 .

In addition, in some embodiments, as shown in FIG. 9, the first friction transmission device 11a further includes: a first synchronous wheel 113a coaxially connected with the first transmission shaft 112a, and the second friction transmission device 11b further includes: The second transmission shaft 112b is coaxially connected to the second synchronous wheel 113b, and, as shown in FIG. 9 and FIG.

Moreover, it should be noted that, in some embodiments, as shown in FIG. 9 , the diameter of the second synchronous wheel 113b is the same as that of the first synchronous wheel 113a, so as to ensure that the first friction member 111a and the second friction member 111b are rotating The rotation speed can be kept consistent, avoiding the phenomenon that the soft towel 100 is torn or wrinkled due to the rotation speed difference between the first friction member 111a and the second friction member 111b during transmission, ensuring the soft towel 100 Flatness of the towel 100 during transport.

In addition, based on the above content, it is not difficult to see that since there are two friction transmission devices 11, namely the first friction transmission device 11a and the second friction transmission device 11b, therefore, based on this, as another alternative, in another In some embodiments, corresponding to the first friction transmission device 11a and the second friction transmission device 11b, as shown in FIG. 12 and FIG.

At the same time, as shown in Figure 12 and Figure 13, the first friction transmission device 11a and the second friction transmission device 11b are arranged in sequence along the conveying direction of the soft towel, and the first friction transmission device 11a and the second friction transmission device 11b are both It is used for frictional contact with the soft towel 100 in the soft towel box.

In addition, as shown in FIGS. 12 and 13 , the first driving device 12 a is connected to the first friction transmission device 11 a. In actual application, as shown in FIG. 14 , the first driving device 12a can drive the first friction transmission device 11a, so that the first friction transmission device 11a can transport the soft towel 100 toward the towel outlet side 41 of the soft towel box , so that the soft towel 100 can be sent out from the towel outlet side 41. Next, as shown in Fig. 12 and Fig. 13, the second driving device 12b is connected with the second friction transmission device 11b, and, as shown in Fig. 14, the second driving device 12b is used for the flexible towel 100 from the When the length sent out from the towel output side 41 reaches the preset length, the second friction transmission device 11b is driven, so that the second friction transmission device 11b transports the soft towel 100 away from the towel output side 41 until the flexible towel 100 is broken , so as to complete the delivery of soft towels of predetermined length. Finally, as shown in Fig. 14, the second driving device 12b is also used to reversely drive the second friction transmission device 11b after the soft towel 100 is broken, so that the second friction transmission device 11b sends the subsequent soft towel 100 into the first A friction transmission device 11a, so that subsequent soft towels can be continuously sent out from the towel output side 41 of the soft towel box by the first friction transmission device 11a when the towels are output next time.

Moreover, it is worth noting that the first friction transmission device 11a and the second friction transmission device 11b adopt the above-mentioned structure, that is, the first friction transmission device 11a cooperates with the first transmission shaft 112a through the first friction member 111a The form realizes the transmission of the soft towel, and the second friction transmission device 11b realizes the transmission of the soft towel through the form of the second friction member 111b cooperating with the second transmission shaft 112b. In some other embodiments, the first friction transmission device 11a and the second friction transmission device 11b can also adopt another structure, for example, as shown in Figure 15 and Figure 16, the first friction transmission device 11a includes: a first The upper friction member 114a, the first lower friction member 115a, the first upper transmission shaft 116a and the first lower transmission shaft 117a. The second friction transmission device 11b includes: a second upper friction member 114b, a second lower friction member 115b, a second upper transmission shaft 116b and a second lower transmission shaft 117b.

Wherein, in order to realize the delivery of the soft towel 100, as shown in FIG. 17, the first upper friction member 114a and the first lower friction member 115a are arranged opposite to each other and in parallel, between the first upper friction member 114a and the first lower friction member 115a The first slit 200a that can transport the soft towel 100 is formed. Secondly, the first upper transmission shaft 116a is coaxially connected with the first upper friction member 114a, and the first lower transmission shaft 117a is coaxially connected with the first lower friction member 115a. At the same time, the first upper transmission shaft 116a or the first lower transmission shaft The shaft 117a is also connected to the first drive device 12a. Moreover, when the first upper transmission shaft 116a is connected with the first driving device 12a, as shown in Figure 15 and Figure 16, the first upper transmission shaft 116a can drive the first upper friction shaft under the driving action of the first driving device 12a. Member 114a rotates. And when the first lower transmission shaft 117a is connected with the first driving device 12a, as shown in Figure 15 and Figure 16, the first lower transmission shaft 117a can drive the first lower friction member under the driving action of the first driving device 12a 115a rotates. It is not difficult to see from this that, as shown in Figure 17, relying on the rotation of the first upper friction member 114a or the first lower friction member 115a, the first upper friction member 114a and the first lower friction member 115a can be respectively opposite to the soft towel 100. A friction force is generated to realize the relative rotation of the first upper friction member 114a and the first lower friction member 115a, so that the soft towel 100 can be sent out through the first gap 200a.

However, in some other embodiments, as shown in Fig. 18 and Fig. 19, the first upper transmission shaft 116a and the first lower transmission shaft 117a can also be connected to the first driving device 12a at the same time, so that the first driving device 12a can Simultaneously drive the first upper transmission shaft 116a and the first lower transmission shaft 117a to rotate relatively, which can improve the friction force of the first upper friction member 114a and the first lower friction member 115a when transporting the soft towel 100, so that the soft towel During the transportation process of the soft towel 100, there will be no slipping phenomenon, which improves the transportation accuracy of the soft towel 100. Moreover, when the first driving device 12a is respectively connected to the first upper transmission shaft 116a and the first lower transmission shaft 117a, as shown in FIG. The first upper driving gear 121a, the first lower driving gear 122a coaxially connected with the first lower transmission shaft 117a, the first gear set 123a meshing with the first upper driving gear 121a and the first lower driving gear 122a respectively, and The first gear set 123a is connected to the first motor assembly 124a. In actual application, the first gear set 123a can be driven by the first motor assembly 124a for meshing transmission, and the first upper driving gear 121a and the first lower driving gear 122a can respectively drive the first gear set 123a under the meshing transmission of the first gear set 123a. An upper transmission shaft 116a and a first lower transmission shaft 117a rotate relative to each other, so as to realize the delivery of the soft towel 100 by the first upper friction member 114a and the first lower friction member 115a.

Moreover, it should be noted that, in some embodiments, as shown in FIG. 18 , the first gear set 123a includes: a first driving gear 1231a coaxially connected with the output shaft of the first motor assembly 124a; 1231a meshes with the first driven gear 1232a, wherein the first driving gear 1231a and the first driven gear 1232a have the same diameter and the same number of teeth, so that when the first driving gear 1231a drives the first driven gear 1232a to rotate, The number of rotations of the two gears can be consistent. At the same time, the first upper driving gear 121a meshes with the first driving gear 1231a, and the first lower driving gear 122a meshes with the first driven gear 1232a, so that the first gear set 123a can realize the first upper driving when meshing transmission. The relative rotation of the gear 121a and the first lower driving gear 122a realizes the delivery requirement of the soft towel 100 by the first upper friction member 114a and the first lower friction member 115a. Of course, in some embodiments, the first lower driving gear 122a can also be meshed with the first driving gear 1231a, and the first upper driving gear 121a can be meshed with the first driven gear 1232a. The first upper driving gear 121a and the first lower driving gear 122a can also achieve relative rotation when the first gear set 123a is meshed for transmission.

In addition, in order to make the soft towel 100 in the transport process, the second friction transmission device 11b can be used to apply the friction force of the soft towel 100 to the first friction transmission device 11a in the opposite direction, so as to break the soft towel 100, in some embodiments Among them, as shown in FIG. 17, the second upper friction member 114b and the second lower friction member 115b are arranged opposite to each other and in parallel, and, as shown in FIG. 7, between the second upper friction member 114b and the second lower friction member 115b A second gap 200b through which the soft towel 100 can pass is formed. Secondly, the second upper transmission shaft 116b is coaxially connected with the second upper friction member 114b, and the second lower transmission shaft 117b is coaxially connected with the second lower friction member 115b. At the same time, the second upper transmission shaft 116b or the second lower transmission shaft The shaft 117b is also connected to the second drive device 12b. When the second upper transmission shaft 116b is connected with the second driving device 12b, as shown in Figure 15 and Figure 16, the second upper transmission shaft 116b can drive the second upper friction member 114b under the driving action of the second driving device 12b to rotate. And when the second lower transmission shaft 117b is connected with the second driving device 12b, as shown in Figure 15 and Figure 16, the second lower transmission shaft 117b can drive the second lower friction member under the driving action of the second driving device 12b 115b rotates. It is not difficult to see from this that in practical application, the first friction transmission device 11a has a frictional force on the soft towel toward the direction of the towel output side 41, while the second friction transmission device 11b relies on the second upper friction member 114b or the second lower friction The rotation of the member 115b can make the second upper friction member 114b or the second lower friction member 115b actively generate a continuous friction force tangential to the rotation direction with the soft towel 100, and the direction of the friction force is away from the towel output The direction of the side 41 makes the soft towel 100 stretched straight and finally broken. Then, the second upper friction member 114b or the second lower friction member 115b is reversely driven by the second driving device 12b. At this time, as shown in FIG. The rubbing direction of 100 is the same as the rubbing direction of the first friction transmission device 11a on the soft towel 100, so that the subsequent remaining soft towels 100 can be filled into the first friction transmission device 11a, thereby ensuring that when the soft towel box is delivered next time, The normal delivery of the follow-up soft towel 100.

However, as an alternative, in some embodiments, as shown in FIG. 19 , the second upper transmission shaft 116b and the second lower transmission shaft 117b can also be connected to the second driving device 12b at the same time, so that the second driving device 12b The second upper transmission shaft 116b and the second lower transmission shaft 117b can be driven to rotate relative to each other at the same time, so that both the second upper friction member 114b and the second lower friction member 115b can actively generate friction with the soft towel 100, so that the soft towel During the conveying process, the towel 100 does not slip, thereby increasing the pulling force on the soft towel 100 and making the soft towel 100 easier to break. Moreover, when the second driving device 12b is connected to the second upper transmission shaft 116b and the second lower transmission shaft 117b respectively, as shown in FIG. 19 , the second driving device 12b includes: coaxially connected with the second upper transmission shaft 116b The second upper driving gear 121b, the second lower driving gear 122b coaxially connected with the second lower transmission shaft 117b, the second gear set 123b meshing with the second upper driving gear 121b and the second lower driving gear 122b respectively, and The second gear set 123b is connected to the second motor assembly 124b. In actual application, the second gear set 123b can be driven by the second motor assembly 124b for meshing transmission, and the second upper driving gear 121b and the second lower driving gear 122b can respectively drive the second gear set 123b under the meshing transmission of the second gear set 123b. The second upper transmission shaft 116b and the second lower transmission shaft 117b rotate relative to each other, thereby increasing the pulling force of the second upper friction member 114b and the second lower friction member 115b on the soft towel 100 .

Moreover, it should be noted that, in this embodiment, as shown in FIG. 19 , the second gear set 123b includes: a second driving gear 1231b coaxially connected with the output shaft of the second motor assembly 124b; 1231b meshes with the second driven gear 1232b, wherein the second driving gear 1231b and the second driven gear 1232b have the same diameter and the same number of teeth, so that when the second driving gear 1231b drives the second driven gear 1232b to rotate, The number of rotations of the two gears can be consistent. At the same time, the second upper driving gear 121b meshes with the second driving gear 1231b, and the second lower driving gear 122b meshes with the second driven gear 1232b, so that the second gear set 123b can realize the second upper driving when meshing transmission. The relative rotation of the gear 121b and the second lower driving gear 122b enables the second upper friction member 114b and the second lower friction member 115b to have greater frictional force on the soft towel 100 , and the soft towel 100 will be broken. Of course, in some embodiments, the second lower driving gear 122b can also be meshed with the second driving gear 1231b, and the second upper driving gear 121b can be meshed with the second driven gear 1232b. The second upper driving gear 121b and the second lower driving gear 122b can also achieve relative rotation when the second gear set 123b is meshed for transmission.

It is worth noting that the structures of the first upper friction member 114a, the first lower friction member 115a, the second upper friction member 114b and the second lower friction member 115b mentioned above are all the same, and can all adopt the same structure as the friction member 111. Therefore, the structure of the first upper friction member 114a, the first lower friction member 115a, the second upper friction member 114b and the second lower friction member 115b will not be described in detail here.

In addition, in some embodiments, as shown in FIG. 20 , the soft towel 100 is provided with several cracks 1001 that can be broken along its length direction, and corresponding to the cracks 1001, as shown in FIG. 20 , the transmission mechanism 1 further includes: A detection element 14, and, as shown in FIG. 21 , the detection element 14 is electrically connected to the processor 6 of the soft towel box, and the detection element 14 is used to transmit between the first friction transmission device 11a and the second friction transmission device 11b The soft towel 100 is detected in real time, and is used to upload the detected soft towel data to the processor 6. Moreover, it should be noted that, in some embodiments, as shown in FIG. 8 and FIG. 9 , the detection element 14 can adopt a visual sensor, and the soft towel data is obtained by the visual sensor, and is sent to the first friction transmission device 11a and Image data of the soft tissue between the second friction transfer device 11b. Or, as shown in FIG. 20, the detection element 14 can also adopt a photoelectric sensor, and the soft towel data is detected by the photoelectric sensor, and is delivered to the soft towel 100 between the first friction transmission device 11a and the second friction transmission device 11b. Leakage data.

In addition, when the first friction transmission device 11a continuously sends out the soft towel 100 from the towel outlet side 41, the processor 6 is also used to judge the length of the soft towel 100 sent out from the towel outlet side 41 according to the received soft towel data, Whether the first preset length is reached, and if it is determined that the first preset length is reached, the second driving device 12b is controlled so that the second driving device 12b drives the second friction transmission device 11a, and the soft towel 100 moves away from the towel output side 41 direction of transport.

Specifically, when the detection element 14 adopts a visual sensor, as shown in FIG. 21, the visual sensor can upload the image data obtained by the soft towel 100 to the processor 6, and the processor 6 will compare the image data with the pre-stored soft towel. 100 compares the image data with cracks, and once the comparison results of the two image data are consistent, the processor can determine the length of the soft towel 100 sent out from the towel output side 41 to reach the first preset length.

Similarly, when the detection element 14 adopts a photoelectric sensor, as shown in FIG. 20 and FIG. 21, the photoelectric sensor can upload the detected light leakage data of the soft towel 100 to the processor 6, and the processor 6 will combine the light leakage data with The pre-stored soft towel 100 is compared with the light leakage data with cracks. Once the comparison results of the two light leakage data are consistent, the processor 6 can determine the length of the soft towel 100 sent out from the output side 41 to reach the first predetermined length. Set the length.

In addition, when the second friction transmission device 11b transports the soft towel 100 in a direction away from the towel outlet side 41, the processor 6 is also used to judge whether the soft towel 100 is broken according to the received soft towel data, and After it is determined that the soft towel 100 is broken, the second driving device 12b is controlled to drive the second friction transmission device 11b to transport the soft towel 100 toward the towel output side 41 by a preset length.

Specifically, when the soft towel data acquired by the processor 6 is the image data of the soft towel 100 uploaded by the visual sensor, as shown in FIG. The image data at that time are compared, and once the comparison results of the two image data are inconsistent, the processor 6 can determine that the soft towel 100 is broken. Similarly, when the soft towel data acquired by the processor 6 is the light leakage data of the soft towel 100 uploaded by the photoelectric sensor, as shown in FIG. 10 and FIG. The light leakage data at the time of tearing are compared, and once the comparison results of the two light leakage data are inconsistent, the processor 6 can determine that the soft towel 100 has been torn off.

Finally, when the second friction transmission device 11b transports the subsequent soft towel 100 towards the direction of the towel outlet side 41, as shown in 20 and FIG. After a friction transmission 1, the first drive 12a and the second drive 12b are switched off. Therefore, when the soft towel box needs to output the towel again, the subsequent soft towel 100 can be output in time under the transmission action of the first friction transmission device 11a.

In addition, some embodiments of the present application also provide a cutting mechanism, as shown in Figure 22 and Figure 23, the cutting structure 2 includes: a cutting device 21 and a driving device 22, wherein the cutting device 21 is used Move along the preset linear direction to cut the soft towel 100 sent out from the delivery side 41 of the soft towel box by the above-mentioned transmission mechanism 1, and secondly, the driving device 22 is connected with the cutter device 21, and the driving device 22 is used for The cutter device 21 is driven to move along a preset linear direction, and, as shown in FIG. Two driving signals.

In addition, the two ends along the preset straight line are the start bit and the stop bit respectively. In some embodiments, as shown in 22 and FIG. 29 , when the drive device 22 receives the first drive signal output by the processor 6, The driving device 22 can drive the cutter device 21 to move from the initial position to the final position. And when the driving device 22 receives the second driving signal, the driving device 22 can drive the cutter device 21 to move from the end position to the start position.

It is not difficult to see from this that the driving of the cutting device 21 by the driving device 22 can make the cutting device 21 move along a preset linear direction. Therefore, when the cutting mechanism 2 is applied to a soft tissue box, it can be used by The above-mentioned transmission mechanism 1 cuts the soft towel sent out from the towel output side 41 of the soft towel box, so that the automatic cutting of the soft towel can also be realized.

Moreover, in some embodiments, as shown in FIG. 22 and FIG. 23 , the cutting knife device 21 includes: a knife seat 211 and a cutting knife 212 . Wherein, the knife seat 211 can move along a preset linear direction, and, as shown in FIG. 24 and FIG. 25 , the knife seat 211 includes: a fixed knife rest 2111 , and a connection assembly 2112 elastically connected to the fixed knife rest 2111 . In addition, the cutting knife 212 is rotatably connected with the connecting assembly 2112. The cutting knife 212 is used to cut the soft towel 100 when the knife seat 211 moves along the preset linear direction. At the same time, the cutting knife 212 is also used to cut the soft towel. The connection assembly 2112 is movable relative to the soft towel.

It is not difficult to see from the above that when the cutter 212 is cutting the soft towel, once the soft towel cannot be cut off, causing the soft towel to gather towards one side and causing greater resistance to the movement of the cutter device 21, the cutter 212 can With the help of the elastic connection between the connection assembly 2112 and the fixed knife holder 2111, the cutting knife 212 can directly pass over the soft towel part that causes resistance to it along its radial direction, thereby effectively avoiding the jamming of the cutting knife device 21 during the cutting process. death phenomenon.

Specifically, in some embodiments, as shown in FIG. 24 and FIG. 25 , the cutting knife 212 is a circular knife, and the circular knife is rotatably connected with the connection assembly 2112 . Therefore, when the cutting knife device 21 moves along the preset linear direction, the round knife can rotate with the help of the frictional resistance with the soft towel 100, thereby improving the cutting force of the round knife when cutting the soft towel 100, thereby improving The success rate of cutting the soft towel 100 once by the cutter device 21. Of course, in some embodiments, the cutting knife 212 can also adopt other shapes, and the structure and shape of the cutting knife 212 are not specifically limited here.

The cutting of the soft towel can be realized by the portion of the round knife protruding from the top side 21111 of the fixed knife holder 2111 .

And, in order to make the round knife movable relative to the soft towel when cutting the soft towel, in some embodiments, as shown in Figure 24 and Figure 25, the direction from the top side 21111 to the bottom side 21112 of the fixed knife holder 2111 A rebound area 21114 communicated with the installation groove 21113 is also formed, so that the connecting assembly 2112 can pass through the rebound area 21114, so that the circular knife can move up and down along its radial direction. It is worth mentioning that, in some embodiments, as shown in FIG. 24 and FIG. 25 , the connection component 2112 can be an elastic arm, and the elastic arm has a fixed end 21121 connected to the top side 21111 , away from the fixed end 21121 The movable end 21122 is provided, and at the same time, the movable end 21122 is also rotatably connected to the axis of the circular knife, and the direction of the elastic arm from the fixed end 21121 to the movable end 21122 spans the rebound area 21114 as a whole. In addition, it is worth noting that when setting the rebound area 21114, the rebound area 21114 can be formed by extending obliquely from the top side 21111 of the fixed tool holder 2111 toward the installation groove 21113. Of course, in some embodiments, the rebound The region 21114 can also be formed extending along a direction parallel to the installation groove 21113 .

It is not difficult to see from this, as shown in Figure 24 and Figure 25, when the round knife is blocked by the rebound zone 21114, there is a certain avoidance space under the elastic arm, so that the round knife can move toward the fixed knife holder through the elastic arm. The direction of the base 1112 of 2111 moves, and when the round knife passes over the blocked soft towel, it can quickly return to its position under the rebound of the elastic arm, thereby preventing the cutting knife device 21 from jamming when cutting the soft towel death phenomenon.

Moreover, in some embodiments, as shown in FIG. 24 , the fixed knife holder 2111 and the elastic arm are also provided with a slot 21115 into which the circular knife can be partially inserted, and the slot 21115 extends along a preset straight direction. By inserting the circular knife into the slot 21115, the fixed knife holder 2111 and the elastic arm can be positioned along the axis of the circular knife to realize the positioning of the circular knife, thereby preventing the circular knife from shaking when rotating. Simultaneously, in order to realize the rotary connection of the round knife and the movable end 21122 of the elastic arm, as shown in Figure 24, the round knife is also provided with a protruding shaft 2121 detachably connected with the elastic arm along its axial direction, and the movable end 21122 of the elastic arm corresponds to The protruding shaft 2121 is provided with a shaft hole 21123 that can be inserted into the shaft hole 21123, and after the protruding shaft 2121 is inserted into the shaft hole 21123, it can be rotatably connected with the movable end 21122. rotation.

Moreover, it is worth noting that when the round knife cuts the soft towel 100, it is movable relative to the soft towel 100 by means of the elastic arm. As an alternative solution, in some embodiments, as shown in FIG. 26 and FIG. 27 , the connection assembly 2112 includes: a moving tool holder 21124 and at least one elastic element 21125 . Wherein, the movable knife rest 21124 is arranged in the mounting groove 21113 of the fixed knife rest 2111 , and the axis of the circular knife is connected to the movable knife rest 21124 in rotation. In addition, as shown in Figure 26 and Figure 27, each elastic element 21125 is arranged between the groove bottom 211131 of the installation groove 21113 and the movable knife rest 21124, so that the movable knife rest 21124 can move relative to the groove bottom 211131 through the elastic element 21125 .

It is not difficult to see from the above content that when the cutting knife device 21 moves along the preset linear direction, since the circular knife and the movable knife holder 21124 are rotatably connected, the circular knife can realize the rotation by means of the frictional resistance with the soft towel 100 , thereby increasing the cutting force of the circular knife on the soft towel 100, and further improving the success rate of cutting the soft towel by the cutting knife device 21 at one time. In addition, when the round knife is unable to cut the soft towel during cutting, and the soft towel gathers to one side to cause greater resistance to the movement of the cutting knife device 21, as shown in Figure 26, the round knife can be arranged on the moving knife again. The elastic element 21125 between the frame 21124 and the groove bottom 211131 of the installation groove 21113, through the resilience of the elastic element 21125, makes the round knife directly pass over the soft towel part that causes resistance to it along its radial direction, thus effectively avoiding the cutting knife The device 21 is jammed during the cutting process.

Specifically, in order to make the round knife realize the rotational connection with the movable knife rest 21124, as shown in Figure 26, the movable knife rest 21124 has a lower surface 211241 opposite to the groove bottom 211131, and an upper surface opposite to the lower surface 211241 211242, and, as shown in Figure 4, the movable knife holder 21124 is provided with a slot 211243 from the upper surface 211242 to the lower surface 211241, the circular knife is partially inserted into the slot 211243, and at the same time, some of the circular knife is protruding On the upper surface 211242 of the moving knife rest 21124. In addition, as shown in Figure 26 and Figure 27, the circular knife forms a protruding shaft 2121 along its axis direction, and at the same time, the movable knife holder 21124 corresponds to the protruding shaft 2121 on the circular knife, and the direction from the upper surface 211242 to the lower surface 211241 can be set The chute 211244 that the protruding shaft 2121 slides into, and when the protruding shaft 2121 slides into the groove bottom of the chute 211244, it can be directly connected to the movable knife rest 21124 for rotation, so that the round knife can be used when cutting soft towels. The frictional resistance produced between the soft towel 100 realizes the rotation.

In addition, as a preferred solution, as shown in FIG. 26 and FIG. 27 , the side of the movable tool holder 21124 relative to the bottom 211131 of the installation groove 21113 protrudes toward the bottom of the groove to form a limiting column 21126 . At the same time, the bottom 211131 of the mounting groove 21113 corresponds to the limit post 21126 and is provided with a limit hole (not marked in the figure) inserted by the limit post 21126, and the limit post 21126 can be vertical to the bottom of the groove 211131 by means of the limit hole. direction to slide. It is not difficult to see that, through the cooperation of the limit post 21126 and the limit hole, the movement of the movable knife rest 21124 can be guided, and the deflection phenomenon occurs when the movable knife rest 21124 moves up and down along the radial direction of the circular knife.

Simultaneously, in order to ensure that when the round knife is blocked, the movable knife rest 21124 can be quickly pressed down to realize the avoidance of the round knife to the blocked soft towel, and at the same time, the movable knife rest 21124 can be activated after passing over the soft towel part that causes resistance to it. Drive the round knife to return quickly. In some embodiments, as shown in Fig. 26 and Fig. 27, the elastic element 21125 is a spring sleeved on the limiting column 21126, and the pressing and rebounding of the spring can be guided through the limiting column 21126, thereby further Improve the kinematic performance of the up and down movement of the moving knife rest 21124.

In addition, it is worth noting that there is only one limiting post 21126 and elastic element 21125, and in some embodiments, the limiting post 21126 and elastic element 21125 can also be increased according to actual usage requirements, and there is no limitation here. The quantity of the post 21126 and the elastic element 21125 is specifically limited.

In addition, in order to enable the driving device 22 to drive the cutting device 21 to move along a preset linear direction, in some embodiments, as shown in FIGS. 22 and 23 , the driving device 22 includes: a pulley assembly 221 and a driving assembly 222 . Wherein, the pulley assembly 221 includes: a first synchronous wheel 2211 and a second synchronous wheel 2212 arranged opposite to each other along a preset linear direction, a synchronous belt 2213 meshing with the first synchronous wheel 2211 and the second synchronous wheel 2212 respectively, the synchronous The belt 2213 is also connected with the fixed knife rest 2111 of the cutting knife device 21 . In addition, in some embodiments, as shown in FIG. 22 and FIG. 23 , the driving assembly 222 includes: a motor 2221 , a driving gear 2222 coaxially connected to the main shaft of the motor 2221 , and the driving gear 2222 is also meshed with the synchronous belt 2213 . At the same time, it should be noted that, as shown in FIG. 29 , the motor 2221 of the drive assembly 222 is also electrically connected to the processor 6, and the motor 2221 can be used to receive the first drive signal and the second drive signal output by the processor 6, and, The motor 2221 can also drive the driving gear 2222 to rotate forward or reverse according to the received first driving signal or the second driving signal, and the synchronous belt 2213 can rotate forward or reversely under the driving gear 2222, The cutter device 21 is driven to move linearly between the start position and the end position.

In addition, in order to further improve the stability of the drive assembly 222 when driving the pulley assembly 221, as shown in Figure 22 and Figure 23, the drive assembly 222 further includes: a first tension pulley 2223 and a second tension pulley 2224, and the first tension pulley 2224 The tensioning pulley 2223 and the second tensioning pulley 2224 are arranged opposite to each other along the preset straight direction, and at the same time, the first tensioning pulley 2223 and the second tensioning pulley 2224 are bypassed by the synchronous belt 2213 for synchronous tensioning The belt 2213, through the first tensioning pulley 2223 and the second tensioning pulley 2224, can increase the tension to the synchronous belt 2213, thereby further improving the stability of the drive assembly 222 when driving the pulley assembly 221, and meanwhile, also The precision when the synchronous belt 2213 drives the tool seat 211 to slide is improved.

However, as an alternative, in some embodiments, the pulley assembly 221 in the driving device 22 can also use other transmission assemblies, for example, as shown in FIG. 30 , the transmission assembly 223 can use a screw drive assembly , and the transmission assembly 223 includes: a screw rod 2231 and a sliding sleeve 2232 sleeved on the screw rod 2231 . Wherein, the sliding sleeve 2232 is threadedly connected with the screw rod 2231. At the same time, the screw rod 2231 is used to be rotatable with its own axis as the pivot axis, and the sliding sleeve 2232 is used for the screw rod 2231 to rotate along the axis direction of the screw rod 2231. sports. In addition, as shown in FIG. 30 , the knife seat 211 of the cutting device 21 can be fixedly connected with the sliding sleeve 2232 , and the cutting device 21 is used to move the sliding sleeve 2232 together with the sliding sleeve 2232 when the sliding sleeve 2232 moves along the axial direction of the screw rod 2231 . sports.

Secondly, in order to be able to drive the screw shaft 2231 to rotate, in some embodiments, the structure of the drive assembly 222 in the drive device 22 can also be changed, for example, the drive assembly 222 includes the aforementioned motor 2221, As shown in FIG. 30 , the drive assembly 222 further includes: a reducer 2225 connected to the main shaft of the motor 2221 , and any end of the screw rod 2231 can be connected to the output end of the reducer 2225 . It is not difficult to find that when the motor 2221 is turned on, the motor 2221 can drive the screw rod 2231 to rotate with its own axis as the pivot axis through the reducer 2225, and the sliding sleeve 2232 can rotate along the screw rod 2231 when the screw rod 2231 rotates. The axial direction moves linearly, so that after the soft towel box finishes discharging the towel, the cutter device 21 can also realize cutting of the soft towel 100 by means of the movement of the sliding sleeve 2232 .

In addition, it is worth mentioning that, when the screw rod 2231 is rotating, in order to avoid the sliding sleeve 2232 from rotating, in some embodiments, as shown in FIG. 30 , the transmission assembly 223 further includes: a guide 2233, and, The guide 2233 is arranged parallel to the threaded rod 2231 . At the same time, the guide piece 2233 is also connected with the sliding sleeve 2232 , and the guide piece 2233 is used to guide the sliding sleeve 2232 when the sliding sleeve 2232 moves along the axial direction of the screw rod 2231 .

For example, in some embodiments, as shown in FIG. 31 , the guide member 2233 may be a slide rail, and the slide rail is provided with a slideway 22331 along a direction parallel to the preset axis, and at the same time, the slide sleeve 2232 is at least partially slidable It is embedded in the slideway 22331, so that when the screw rod 2231 is rotating, the sliding sleeve 2232 can slide along the length direction of the slideway 22331. However, in some other embodiments, as shown in FIG. 30 , the guide member 2233 can also be a guide rod, and the guide rod passes through the sliding sleeve 2232 and is slidably connected with the sliding sleeve 2232, so that when the screw rod 2231 is rotating, it can Make the sliding sleeve 2232 slide along the length direction of the guide rod. It is not difficult to see from this that by embedding the sliding sleeve 2232 in the slideway 22331 of the sliding rail 2233, or passing the guide rod through the sliding sleeve 2232, the sliding sleeve 2232 can be guided and limited to prevent the screw rod 2231 from rotating. Sliding sleeve 2232 appears to turn with the phenomenon.

Finally, in some other embodiments, as shown in FIG. 32 , the transmission assembly 223 further includes: a rack 2234 and a gear 2235 . Wherein, the rack 2234 is arranged parallel to the screw rod 2231 , meanwhile, the gear 2235 is rotatably arranged on the sliding sleeve 2232 and meshes with the rack 2234 . Therefore, by virtue of the meshing of the gear 2235 and the rack 2234 , the stability of the sliding sleeve 2232 when moving along the axial direction of the screw rod 2231 can be improved.

In addition, it is worth mentioning that, in some embodiments, as shown in FIG. 28 , the cutting mechanism 2 further includes: a detection device 23, and the detection device 23 is composed of a first Hall element 231 and a second Hall element 232, and, as shown in FIG. 29, both the first Hall element 231 and the second Hall element 232 are electrically connected to the processor 6. Therefore, the first Hall element 231 can be used to detect the position of the cutting device 21 when the cutting device 21 moves toward the end position, and at the same time, the first Hall element 231 is also used to detect the movement of the cutting device 21 When the stop bit is reached, the first sensing signal is output to the processor 6 . The second Hall element 232 is used to detect the position of the cutting knife device 21 when the cutting knife device 21 moves toward the initial position. At the same time, the second Hall element 232 is also used for detecting that the cutting knife device 21 moves to When the start bit is selected, the second sensing signal is output to the processor 6 . Moreover, as shown in FIG. 29 , when the processor 6 receives the first sensing signal, it means that the cutting device 21 has moved to the end position at this time, and at this time, the processor 6 can output the second driving signal to the driving device 22 , so that the driving device 22 can drive the cutting device 21 to move towards the starting position. And when the processor 6 receives the second sensing signal, it means that the cutter device 21 has moved to the initial position at this time, and the homing is completed. At this time, the processor 6 can turn off the driving device 22 .

It is not difficult to see from the above content that the detection of the position of the cutting knife device 21 by means of the first Hall element 231 and the second Hall element 232 can enable the processor 6 to achieve precise control of the driving device 22, so that the cutting mechanism 2 It can realize automatic cutting of soft towels during transmission.

In addition, as shown in FIG. 23 and FIG. 28 , in some embodiments, the cutting mechanism 2 includes: a hidden blade 24 . Moreover, the knife hiding part 24 is arranged along a preset linear direction. The knife hiding part 24 has a lower surface 2412 opposite to the knife seat 211 and an upper surface 2411 opposite to the lower surface 2412 . At the same time, the knife hiding part 24 is also provided with a knife hiding slit 243 , and the knife hiding slit 243 also extends along a preset linear direction. In application, as shown in Figure 23 and Figure 28, some of the round knives are embedded in the hidden knife slit 243, and at the same time, some of the round knives protrude from the upper surface of the hidden knife piece 24 through the hidden knife slit 243 2411 , this part is used for cutting the transported soft towel 100 when the cutter device 21 moves along the preset linear direction.

It is not difficult to find that by setting the hidden knife part 24 and hiding a part of the round knife in the hidden knife slit 243, the safety of the soft towel box can be improved, and the round knife can be effectively prevented from being damaged during the cutting process. Misoperation by the user may cause damage to the user. Moreover, it should be noted that, in some embodiments, as shown in Fig. 23 and Fig. 28, the knife hiding part 24 is actually composed of a knife hiding strip 241 and a cover plate 242 arranged on the lower shell 4 of the soft towel box, Moreover, the hidden knife bar 241 and the cover plate 242 are separated from each other to form a hidden knife slit 243 . Of course, in some embodiments, the knife hiding part 24 can also be a whole structure, and the knife hiding slit 243 is opened directly on the knife hiding part 24 along the preset linear direction, and the structure of the knife hiding part 24 is not aligned here. , and the form of the hidden knife slit 243 on the hidden knife piece 24 is specifically limited.

In addition, it is worth noting that, in addition to the combination of the knife seat 211 and the knife 212, the cutting knife device 21, as another alternative, in some embodiments, as shown in Figure 34 and Figure 35, the cutting knife device 21 It includes: a cutting knife 212 rotatable around a preset axis as a pivot axis, and a transmission assembly 213 connected with the cutting knife 212 . Moreover, as shown in FIG. 33 , when the driving device 22 drives the cutter device 21 to move along the preset linear direction, the transmission assembly 213 can also drive the cutter 212 to rotate around the preset axis as the pivot axis, and the preset axis is the axis of the cutter 212 itself. It is not difficult to find that the linear motion of the cutter device 21 can make the transmission assembly 213 drive the cutter 212 to rotate synchronously, so that the soft towel is not easy to accumulate and deform relative to the cutter 212 during the linear motion of the cutter 212, and can The soft towel has a better cutting effect, which further ensures that the cutting knife 212 can completely cut the soft towel, so that the soft towel can be cut at one time during the linear movement of the cutting knife device 21, thereby ensuring that the soft towel is cut Flatness of the back section.

Specifically, in some embodiments, as shown in FIG. 34 and FIG. 35 , the cutter device 21 further includes: a bracket 214, and both the cutter 212 and the transmission assembly 213 are arranged on the bracket 214. At the same time, referring to FIG. 33 As shown, the cutter 212 is also rotatably connected to the bracket 214, and the bracket 214 is also connected to the driving device 22, so that the driving device 22 can drive the bracket 214 to move along a preset linear direction.

In addition, in order to enable the driving device 22 to drive the cutter device 21 to move along a preset linear direction, the transmission assembly 213 of the cutter device 21 can also drive the cutter 212 to rotate, as shown in FIG. 33 , the cutting mechanism 2 It also includes: a rack 25 , and the rack 25 is formed extending along a preset linear direction, that is, the preset linear direction is the length direction of the rack 25 . And, corresponding to the rack 25, as shown in Figure 34 and Figure 35, the transmission assembly 213 includes: a first transmission shaft 2131, a driving gear 2132, a second transmission shaft 2133, a first driven gear 2134 and a second driven gear 2135. Wherein, as shown in Fig. 34 and Fig. 35, the first transmission shaft 2131 is rotatably arranged on the bracket 214, and the cutter 212 and the driving gear 2132 are coaxially connected with the first transmission shaft 2131 along the preset axis direction, After the cutter 212 and the driving gear 2132 are installed on the first transmission shaft 2131 , the driving gear 2132 can be located on any side of the cutter 212 along the preset axis direction.

In addition, it is worth noting that, as shown in Figure 34 and Figure 35, the second transmission shaft 2133 can be installed in the same way as the first transmission shaft 2131, that is, the second transmission shaft 2133 can also be set on the bracket 214 in a rotatable form , and the second transmission shaft 2133 is also arranged parallel to the first transmission shaft 2131, in addition, the first driven gear 2134 and the second driven gear 2135 are coaxially connected with the second transmission shaft 2133, meanwhile, combined with the As shown, the second driven gear 2135 is meshed with the driving gear 2132, and the first driven gear 2134 is meshed with the rack 25. Therefore, when the driving device 2 drives the bracket 214 to move along the preset linear direction, as shown in FIG. When rotating, the second driven gear 2135 can be driven by the second transmission shaft 2133 to follow the rotation, and when the second driven gear 2135 is rotating, it can further drive the second driven gear 2132 through the driving gear 2132 by meshing with the driving gear 2132. A transmission shaft 2131 rotates, so that the cutter 212 connected with the first transmission shaft 2131 is rotated. It is not difficult to find that, with the help of the transmission assembly 213, the cutter device 21 can drive the cutter 212 to rotate while moving along the preset linear direction. Therefore, the cutting effect of the cutter 212 on the soft towel 100 can be increased. The cutting force makes the soft towel 100 easier to be cut.

In addition, in order to enable the driving device 22 to drive the bracket 214 to move along a preset linear direction, in some embodiments, corresponding to the structure of the above-mentioned transmission assembly 213, the driving device 22 can adopt another structure, for example, as shown in Figure 33 As shown, the driving device 22 includes: a motor (not shown in the figure), a driving gear 225 , a first synchronous wheel 226 , a second synchronous wheel 227 and a synchronous belt 228 . Wherein, as shown in Figure 33, the driving gear 225 is coaxially connected with the main shaft of the motor, and the first synchronous wheel 226 and the second synchronous wheel 227 are arranged opposite to each other along the preset linear direction, in addition, the synchronous belt 228 is also connected with the driving gear 225, the first synchronous wheel 226 and the second synchronous wheel 227 are engaged, simultaneously, as shown in Figure 33 and Figure 34, support 214 can also be arranged between the first synchronous wheel 226 and the second synchronous wheel 227, and its It is fixedly connected with the synchronous belt 228, so that when the motor 224 drives the driving gear 225 to rotate, the driving gear 225 can synchronously drive the synchronous belt 228 for transmission by engaging with the synchronous belt 228, and the first synchronous wheel 226 and the second synchronous wheel 227 The rotation can be realized under the transmission of the synchronous belt 228, so as to realize the linear movement of the bracket 214 between the first synchronous wheel 226 and the second synchronous wheel 227, so as to complete the cutting of the soft towel 100 by the cutter 212. Moreover, it should be noted that, in order to avoid slippage between the timing belt 228 and the bracket 214 during transmission, as shown in FIG. In the embodiment, the bracket 214 can also be connected with the timing belt 228 in other forms. For example, locking parts such as bolts can be used between the bracket 214 and the timing belt 228, but not between the bracket 214 and the timing belt 228. The connection method is specifically limited.

Moreover, in order to further improve the transmission performance of the synchronous belt 228 when the drive bracket 214 moves along a preset linear direction, in some embodiments, as shown in FIG. The tension wheel 229 is arranged between the first synchronous wheel 226 and the second synchronous wheel 227. Simultaneously, the tension wheel 229 is also bypassed by the synchronous belt 228. The tension wheel 229 can not only guide the synchronous belt 228, but also Increase the tension of the synchronous belt 228 during transmission, thereby improving the transmission performance of the synchronous belt 228 .

In addition, in addition to cutting the flexible 100 by the cutting knife 212 in the form of a circular knife, in some embodiments, the cutting knife 212 can also adopt other structures. For example, as shown in FIG. The direction has an inner side 2122, and an outer side 2123 disposed coaxially opposite the inner side 2122. Moreover, the outer side 2123 includes at least one edge 21231 around the predetermined axis. In addition, when one cutting edge 21231 is provided, the cutting knife 212 can be a round knife.

However, in some embodiments, as shown in FIG. 36 , multiple cutting edges 21231 can also be provided, and when there are multiple cutting edges 1121, each cutting edge 21231 is arranged in sequence around the preset axis direction, and each The cutting edge 21231 can also be connected successively around the preset axis direction, and every part where two adjacent cutting edges 21231 are connected forms a cutting edge 21232 . Therefore, when the cutter 212 is rotating, the cutting force on the soft towel 100 can be further improved, thereby having a better cutting effect on the soft towel 100, so that the soft towel can be cut once during the linear movement of the cutter 212. Cutting ensures the flatness of the section after the soft towel 100 is cut.

Moreover, it should be noted that, in some embodiments, the preset axis direction is the central axis direction of the cutting knife 212, so that the cutting knife 212 can realize self-rotation with the central axis as the pivot axis. As shown in FIG. 36 , the cutting knife 212 There are eight cutting edges 21231 in total, and the lengths of each cutting edge 21231 are the same, and the angles of the cutting edges 21232 formed between every two adjacent cutting edges 21231 are the same. It is not difficult to see from this that the shape of the entire cutting knife 212 is approximately a regular octagonal structure. Therefore, the edge angle 21232 formed between every two adjacent edge edges 21231 is an obtuse angle. Of course, in some embodiments, the number of cutting edges 21231 can also be increased or decreased accordingly according to requirements. For example, when there are three cutting edges 21231, the shape of the entire cutting knife 212 is approximately a regular triangle, and adjacent The edge angle 21232 formed between the two edge edges 21231 is an acute angle of 60 degrees. In addition, it should be noted that each cutting edge 21231 can be a straight edge, or as shown in FIG. 36 , can also be an outwardly convex arc edge. Moreover, when each cutting edge 21231 is an arc-shaped edge, the cutting force of each cutting edge 21231 on the soft towel 100 can be further improved.

In addition, it is worth mentioning that, in order to facilitate the installation and fixation of the entire cutter 212, as shown in FIG. The cutting knife 212 can be locked and fixed with the first transmission shaft 2131 through each locking protrusion 2124 , so that the cutting knife 212 can be driven and rotated by the first transmission shaft 2131 . In order to further facilitate the clamping and fixing of the cutter 212 and the transmission shaft, the side of the clamping protrusion 113 away from the inner side is a concave arc surface 21241, so that the clamping protrusion 2124 is engaged with the first transmission shaft 2131 , it can fully fit with the outer surface of the first transmission shaft 2131 . Moreover, in some embodiments, as shown in FIG. 4 , each snap-in protrusion 2124 is also equidistantly arranged around the predetermined axis direction, and through a plurality of snap-in protrusions 2124 , the cutter 212 exerts force on the first transmission shaft 2131 . The clamping force can be evenly distributed on the outer surface of the first transmission shaft 2131 around the preset axis direction, so that after the cutter 212 is installed, the stability and reliability of the installation of the cutter 212 can be guaranteed.

In addition, some embodiments provide a soft towel box, as shown in Figure 1, Figure 2 and Figure 37, the soft towel box includes: a lower shell 4, an upper cover 5, the above-mentioned transmission mechanism 1 and a processor 6 . Wherein, the lower case 4 is used for installing the consumable soft towel 10 , and the upper cover 5 is reversible relative to the lower case 4 for opening or closing the lower case 4 .

In addition, as shown in FIG. 3 and FIG. 5 , the transport mechanism 1 is used to transport the soft towel 100 in the soft towel consumable 10 toward the direction of the towel output side 41 . Finally, as shown in FIG. 37 , the processor 6 is electrically connected to each driving device 12 of the conveying mechanism 1, and the processor 6 is used to receive the command to output the towel, and is used to send instructions to each driving device after receiving the command to output the towel. 12 outputs a drive signal, and the drive device 12 can drive at least one friction transmission device 11 after receiving the drive signal, so that at least one friction transmission device 11 can transport the soft towel 100 toward the towel output side 41.

In addition, some embodiments also provide a soft towel box, as shown in Fig. 1, Fig. 2 and Fig. 38, the soft towel box includes: the above-mentioned lower shell 4, upper cover 5, transmission mechanism 1 and In addition to the processor 6, as shown in FIG. 22, the soft towel box also includes: the cutting mechanism 2 as described above. Moreover, the driving device 22 of the cutting mechanism 2 is also electrically connected to the processor 6 .
