For example, "connection" can be a fixed connection or a detachable connection. , or integrally connected, or electrically connected; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in various embodiments of the present application can be understood according to specific circumstances.

In the description of various embodiments of the present application, the direction pointed by arrow x in all drawings is the length direction, the direction pointed by arrow y is the width direction, and the direction pointed by arrow z is the vertical direction. The horizontal direction is a direction parallel to the horizontal plane, and may be the above-mentioned length direction or the above-mentioned width direction. In addition, the horizontal direction not only includes the direction that is absolutely parallel to the horizontal plane, but also includes the direction that is generally parallel to the horizontal plane as commonly recognized in engineering. The vertical direction is the direction perpendicular to the horizontal plane. The vertical direction not only includes the direction absolutely perpendicular to the horizontal plane, but also includes the direction generally perpendicular to the horizontal plane that is conventionally recognized in engineering. In addition, directional words such as "upper", "lower", "top", and "bottom" described in this application are understood relative to the vertical direction.

Because there are currently some tissue boxes that can realize automatic conveying and cutting of tissue, but when cutting the tissue, the cutter of the tissue box is generally driven to move laterally. However, the inventor found that because the tissue itself has softness and quality Due to its lighter nature, during the cutting process, it is easy for the tissue paper itself to have no point of force, causing the cutter to be unable to cut the soft tissue at one time, and the uncut portion of the soft tissue will move laterally with the cutter. The paper towels are driven down and gathered together. During the gathering process, the thickness of the paper towels will be increased, which will cause greater resistance to the movement of the cutter. As a result, the paper towels will often get stuck when the cutters are moving, causing the paper towels to get stuck. The cutter is stuck.

Based on this, some embodiments provide a cutting device for a soft towel box, as shown in Figures 1 and 2. The cutting device 1 is used to move in a preset linear direction to cut soft towels transported by the soft towel box. 100, and, as shown in Figure 1, the cutting device 1 includes: a first cutting knife 11 and a second cutting knife 12.

As shown in Figures 1 and 2, the first cutting knife 11 and the second cutting knife 12 are movable relative to each other, and a cutting edge for cutting soft towels is formed between the first cutting knife 11 and the second cutting knife 12. area 13, and when the first cutting knife 11 and the second cutting knife 12 move toward each other, the cutting area 13 can be closed and the conveyed soft towel 100 can be cut. When the first cutting knife 11 and the second cutting knife 12 move in the direction away from each other, the cutting area 13 can be opened and the soft conveying The towel 100 can pass through the cutting area 13.

It is easy to see from the above that after the transfer of the soft towel 100 is completed, the cutting of the soft towel 100 can be completed by operating the first cutting knife 11 and the second cutting knife 12, so that after the soft towel 100 is cut, It can ensure the smoothness of the cross section of the soft towel 100, and at the same time, it also makes the operation of the soft towel 100 very convenient when cutting. Moreover, since the cutting direction of the first cutting knife 11 and the second cutting knife 12 on the soft towel 100 is relative to the soft towel 100, therefore, the first cutting knife 11 and the second cutting knife 12 are cutting the soft towel 100. When the soft towel 100 is not subjected to lateral resistance, the soft towel 100 will not be gathered to one side, thereby effectively improving the success rate of the cutting device 1 for cutting the soft towel 100 at one time, and when the soft towel 100 cannot be cut at one time, due to The first cutting knife 11 can move linearly in a direction away from the second cutting knife 12. Therefore, jamming of the cutting knife device 1 can be avoided.

Specifically, in some embodiments, as shown in FIGS. 1 and 2 , one side of the first cutting knife 11 relative to the second cutting blade 12 is the first blade 111 , and the second cutting blade 12 is located relative to the first blade 111 . One side of the cutting knife 11 is the second blade 121 . Moreover, when the first cutting knife 11 and the second cutting knife 12 move toward the preset position in the direction of approaching each other, the first blade 111 and the second blade 121 fit together, so that the soft towel 100 can be cut. .

Moreover, in order to ensure that the first cutting knife 11 and the second cutting knife 12 can cut the towel 100 at one time when the first cutting knife 11 and the second cutting knife 12 move relative to each other, as shown in Figures 1 and 2, when the first cutting knife 11 and the second cutting knife 12 When moving relative to each other, the first blade 111 of the first cutter 11 and/or the second blade 121 of the second cutter 12 may be in line contact with the towel 100. For example, in some embodiments, as shown in Figure 1 As shown in Figure 2, the second blade 121 of the second cutting blade 12 is in line contact with the towel 100, and the second blade 121 of the second cutting blade 12 includes: a flat surface 1211 and an inclined surface 1212, and the flat surface 1211 is connected to the inclined surface 1212, and the connected part constitutes the blade part of the second blade part 121, so that the first cutting knife 11 and the second cutting knife 12 can achieve line contact with the towel 100 when they move relative to each other. In the first cutting knife 11, the first cutting knife 11 can adopt the same structure as the second cutting knife 12. Of course, other structures can also be adopted. However, in this embodiment, the second cutting knife 12 and the first cutting knife 12 are not connected. The structure of the knife 11 is specifically limited.

It is easy to see from this that when the soft towel 100 is cut, the linear contact between the first blade 111 of the first cutting knife 11 and/or the second blade 121 of the second cutting knife 12 and the soft towel 100 , can improve the cutting force of the first cutting knife 11 and the second cutting knife 12 when cutting the soft towel 100, thereby improving the ability of the first cutting knife 11 and the second cutting knife 12 to cut the soft towel 100 at one time when the first cutting knife 11 and the second cutting knife 12 move relative to each other. success rate. In addition, it should be noted that in order to achieve a better cutting effect on the towel 100 when the first cutting knife 11 and the second cutting knife 12 move relative to each other, in some embodiments, the first blade 111 and the second cutting knife 12 are The sides of the second blade portions 121 that are in contact with each other are both flat surfaces, so that when the first cutting knife 11 and the second cutting knife 12 cut the towel 100, the first cutting knife 11 and the second cutting knife 12 The cutting force on the soft towel 100 is perpendicular to the soft towel 100, thereby avoiding the first blade 111 or the second blade 121 from generating a lateral pulling force on the soft towel 100, thereby further improving the first cutting knife 11 and the Second cutter 12The success rate of cutting soft towels at one time when moving relative to each other.

In addition, it is worth mentioning that in some embodiments, as shown in Figures 1 and 2, the first cutting knife 11 is a first cutting knife, and the second cutting knife 12 is a fixed knife, that is, a first cutting knife 11 is movable relative to the second cutting knife 12 , and the second cutting knife 12 is fixed relative to the first cutting knife 11 . For example, as shown in FIGS. 1 and 2 , the first cutting knife 11 is rotatable relative to the second cutting knife 12 . Moreover, in order to realize the rotation of the first cutting knife 11, as shown in FIG. 1, the first cutting knife 11 and the second cutting knife 12 are hinged through the hinge shaft 14. Therefore, the first cutting knife 11 and the second cutting knife 11 are hinged. The knives 12 can rotate relative to each other about a hinge axis 14 .

In addition, in other embodiments, as shown in FIGS. 1 and 2 , the hinge shaft 14 can be fixedly connected to the first cutter 11 , and at the same time, the hinge shaft 14 can also be rotationally connected to the second cutter 12 . Therefore, the hinge shaft 14 can be directly connected to the external driving device, so that the driving device can drive the first cutting knife 11 to rotate relative to the second cutting knife 12 through the hinge shaft 14, thereby realizing automatic cutting of the soft towel 100. Moreover, when the hinge shaft 14 drives the first cutting knife 11 to rotate, since the hinge shaft 14 and the second cutting knife 12 are rotationally connected, the second cutting knife 12 will not be caused by the hinge shaft 14 rotation, resulting in the phenomenon of follow-up rotation. Moreover, it is worth noting that, in order to achieve a rotational connection between the second cutter 12 and the hinge shaft 14, a bushing (not labeled in the figure) can be provided between the second cutter 12 and the hinge shaft 14, and a sleeve can be provided between the second cutter 12 and the hinge shaft 14. The inner ring of the shaft sleeve is fixedly connected to the hinge shaft 14, and at the same time, the outer ring of the shaft sleeve is fixedly connected to the second cutter 12, so that the hinge shaft 14 can only drive the first cutter 11 during rotation. The rotation will not drive the second cutting knife 12 to rotate, so that the first cutting knife 11 can rotate relative to the second cutting knife 12 to complete the cutting of the soft towel 100 .

It should be noted that the above solution only takes the rotation of the first cutting knife 11 relative to the second cutting knife 12 as an example. In other embodiments, the first cutting knife 11 can also be used as a fixed knife, and accordingly , the second cutting knife 12 can be used as the first cutting knife, and, in other embodiments, the second cutting knife 12 can also be fixedly connected with the hinge shaft 14, and the first cutting knife 11 is connected with the hinge shaft 14. 14 is rotatably connected, so that the second cutting knife 12 can rotate relative to the first cutting knife 11, so that the soft towel 100 can also be cut.

In addition, in some embodiments, as shown in FIG. 3 , at least one of the first cutting knife 11 and the second cutting knife 12 is arranged obliquely relative to the other cutting knife. Therefore, when the first cutting knife 11 moves to the preset position in the direction close to the second cutting knife 12, the first blade 111 of the first cutting knife 11 can just offset the second blade 121 of the second cutting knife 12, And can fit with the second blade of the second cutting knife 12, so that during the process of cutting the soft towel 100, a large shearing force can be generated on the soft towel 100.

In addition, it is worth mentioning that in some embodiments, the first blade 111 of the first cutting knife 11 is a flat blade, and the first blade 111 includes: a first blade tip 1111 and a first blade tip 1111 The connected first edge 1112. Similarly, the second blade 121 of the second cutting knife 12 is also a flat blade, and the second blade 121 includes: a second blade tip 1211 and a second blade tip 1211 . The second edge 1212 connected to 1211. Moreover, in some embodiments, as shown in FIG. 6 , the first edge 1112 of the first blade 111 is a bevel, and the second edge 1212 of the second blade 121 is a plane, so that the first cutting edge 1112 is a bevel. When the knife 11 moves in the direction of the second cutting knife 12, through the cooperation of the first blade tip 1111 of the first blade part 111 and the second blade tip 1211 of the second blade part 121, a larger cut can be made on the soft towel. Cutting force. Moreover, it should be noted that the second blade edge 1212 of the second blade portion 121 is only explained using a plane as an example. In other embodiments, as shown in FIG. 3 , the second blade edge 1212 of the second blade portion 121 is 212 may also be an inclined surface, through which the shearing force of the first cutting knife 1 and the second cutting knife 12 when cutting soft towels can be further improved.

Of course, in other embodiments, when the first cutting knife 11 and the second cutting knife 12 move in opposite directions to each other, as shown in FIGS. 1 and 2 , the first blade 111 and the second blade 121 It can also be gradually closed from one end to the other end, so that the cutting device 1 can approximate the cutting method of scissors when cutting the towel 100, so that the first cutting knife 11 and the second cutting knife 12 are moving toward each other. When moving in opposite directions, the shearing force generated by the first blade 111 and the second blade 121 on the towel 100 can be further increased, making the towel 100 easier to cut. Alternatively, when the first cutting knife 11 and the second cutting knife 12 move in opposite directions to each other, as shown in FIG. The blade portion 121 gradually closes, or the second portion and the first portion of the first blade portion 111 along its length direction gradually close with the second blade portion 121 . Moreover, when the second part of the first blade part 111 and the second blade part 121 gradually come together, the first part of the first blade part 111 and the second blade part gradually separate. When the first part 111A of the first blade part 111 and the second blade part 121 gradually come together, the second part of the first blade part 111 and the second blade part 121 gradually separate. Wherein, the first part and the second part of the first blade part 111 are also arranged sequentially along the length direction of the first blade part 111 . Therefore, when the entire first cutting knife 11 cooperates with the second cutting knife 12 to cut the soft towel, the first cutting knife 11 and the second cutting knife 12 can produce a large shearing force on the soft towel 100, so that the cutting device 1 The soft towel can be cut at one time, thereby ensuring the smoothness of the cross section of the soft towel after cutting, and making it convenient for users to operate the soft towel box. Of course, in other embodiments, as shown in FIG. 10 , the first cutting knife 11 and the second cutting knife 12 may also move linearly in opposite directions to each other. However, in this embodiment, the first cutting knife 11 and the second cutting knife 12 are not used. The manner in which the knife 11 and the second cutting knife 12 move relative to each other is specifically limited.

In addition, some embodiments also provide a cutting knife pressing device, as shown in Figures 5 and 6. The cutting knife pressing device 2 is used to press the first cutting knife 11 of the cutting device 1 as described above. , where, as shown in Figures 5 and 6, the first cutting knife 11 of the cutting device 1 is movable relative to the second cutting knife 12, and at the same time, the second cutting knife 12 is fixed, and the cutting knife is pressed The device 2 includes: a pressing member 21 and a supporting arm 22 . Among them, as shown in FIG. 5 and FIG. 6 , the pressing member 21 is attached to the first cutting knife 11 of the cutting device 1 . Secondly, as shown in FIG. 5 , the support arm 22 has a fixed side 221 and is disposed away from the fixed side 221 . The supporting side 222, and as shown in FIG. 6, the supporting side 222 is used to support the pressing member 21, and the fixed side 221 can be fixedly connected with the housing 40 of the soft towel box or the bracket 4 of the soft towel box.

Furthermore, in some embodiments, as shown in FIGS. 5 and 6 , at least part of the support arm 22 from the fixed side 221 to the support side 222 is bent toward the direction of the first cutting knife 11 . Therefore, through the bent portion of the support arm 22, when the first cutting knife 11 moves relative to the second cutting knife 12 of the cutting device 1, the pressing member 21 can always press the first cutting knife 11, thereby ensuring that the first cutting knife 11 moves relative to the second cutting knife 12 of the cutting device 1. When the first cutting knife 11 moves to the preset position in the direction of the second cutting knife 12, the first blade 111 of the first cutting knife 11 and the second blade 121 of the second cutting knife 12 can be interlaced with each other and closely attached to each other. Therefore, a large shear force can be generated on the soft towel 100, so that the cutting device 1 can cut the soft towel 100 at one time, which not only ensures the smoothness of the cross section of the soft towel 100 after cutting, but also facilitates the user to cut the soft towel 100. Box operation.

Specifically, as shown in FIGS. 5 and 6 , the support arm 22 includes: a support arm body 223 and a support base 224 . The support arm body 223 extends from the fixed side 221 to the support side 222 . At the same time, at least part of the support arm body 223 is bent in the direction of the first cutting knife 11 . In addition, as shown in FIG. 5 , the support seat 224 is provided on the support side 222 , and as shown in FIG. 6 , the support seat 224 is connected to the support arm body 223 , and the pressing member 21 can be supported and fixed through the support seat 224 . Therefore, the part of the pressing member 21 that is bent toward the first cutting knife 11 by means of the support arm body 223 can enable the pressing member 21 to always press the first cutting knife 11 to ensure that the first cutting knife 11 is moving toward the second cutting knife. When the cutting blade 12 moves to the preset position, the first blade 111 of the first cutting blade 11 and the second blade 121 of the second cutting blade 12 can be in close contact with each other.

In addition, it is worth mentioning that in other embodiments, as shown in Figures 5 and 6, the support arm body 223 includes: a curved section 2231 and a vertical section 2232. Moreover, the curved section 2231 is bent and extended from the fixed side 221 to the supporting side 222 , and the vertical section 2232 is connected to an end of the curved section 2231 away from the fixed side 221 . At the same time, the support base 224 is also arranged perpendicularly to the vertical section 2232 . It is not difficult to see from this that the support base 224 can be connected through the vertical section 2232, so that the support base 224 can effectively fix and support the pressing member 21, and the curved section 2231 can be fixed on the support base 224. The pressing member 21 always presses the first cutting knife 11 to ensure that when the first cutting knife 11 moves to the preset position relative to the second cutting knife 12, the first blade 111 of the first cutting knife 11 is in contact with the second cutting knife 11. The second blade 121 of the cutting knife 12 is in close contact with each other, thereby increasing the shearing force of the first cutting knife 11 and the second cutting knife 12 when cutting soft tissue.

In addition, in this embodiment, in order to realize the fixed support of the pressing member 21 by the support seat 224, as shown in Figures 5 and 6, the support seat 224 includes: at least one support plate 2241 arranged perpendicular to the vertical section 2232, Moreover, each support plate 2241 is provided with a slot 2242 on the side away from the support side 222 that can be clamped by the pressing member 21. Therefore, in some embodiments, by clamping the pressing member 21 into the slot 2242, the support is The seat 224 can support and limit the pressing member 21 to ensure that each support plate 2241 of the supporting seat 224 can always have a direction toward the first cutting knife 11 for the pressing member 21 under the action of the curved section 2231. force, so that the pressing member 21 can always press the first cutting knife 11 to ensure that when the first cutting knife 11 and the second cutting knife 12 cut the towel 100, the first blade 111 and the second blade 121 can fit closely, thereby increasing the shearing force of the first cutting knife 11 and the second cutting knife 12 when cutting the soft towel 100 . Moreover, it should be noted that when the support plate When multiple support plates 2241 are provided, as shown in FIG. 5 , each support plate 2241 can be arranged sequentially along the axial direction of the pressing member 21 . Multiple support plates 2241 can increase the supporting force of the support base 224 for the pressing member 21 .

In addition, in other embodiments, as shown in FIG. 5 , two support arms 22 are provided, and the two support arms 22 are arranged oppositely along the axial direction of the pressing member 21 . Therefore, the two support arms 22 can respectively support and fix the two ends of the pressing member 21 to ensure that the force of the pressing member 21 when pressing the first cutting knife 11 can be directed from both ends of the first cutting knife 11 to The center position of the first cutting knife 11 gradually spreads, so that the force exerted by the pressing member 21 on the first cutting knife 11 can be relatively evenly distributed throughout the first cutting knife 11 , so that the first cutting knife 11 and the second cutting knife 11 The knife 12 has good stability when cutting the soft towel 100, which prevents the first cutting knife 11 from being partially affected by the pressing force of the pressing member 21 and affecting the cutting of the soft towel 100.

Moreover, it is worth mentioning that, in order to enable the pressing member 21 to always press the first cutting knife 11 under the action of the support arm 22, in some embodiments, as shown in FIG. 6, the pressing member 21 is a pressing member. The pressing roller includes: a stick body 211 and a connecting shaft 212 coaxially connected to the stick body 211, and both ends of the connecting shaft 212 are exposed outside the stick body 211. Moreover, in some embodiments, as shown in FIGS. 5 and 6 , either end of the connecting shaft 212 can be connected to one of the support arms 22 , that is, the end of the connecting shaft 212 is clipped into each of the supporting seats 224 . In each slot 2242 of the support plate 2241, at the same time, connect the other end of the connecting shaft 212 with the other support arm 22, that is, the other end of the connecting shaft 212 is clamped into each supporting plate 2241 of the other support base 224. In the card slot 2242. It is not difficult to see from this that by the two support seats 224 respectively clamping the two ends of the connecting shaft 212, the pressing roller can continuously and stably apply force to the first cutter 11, and at the same time, the pressing roller can While resisting the first cutting knife 11, it can also rotate under the movement of the first cutting knife 11. Therefore, when the first cutting knife 11 moves relative to the second cutting knife 12, it will not cause any damage to the first cutting knife 11. Greater movement resistance. Of course, in other embodiments, the pressing member 21 may also be made of other components, but in this embodiment, the structure of the pressing member 21 is not specifically limited.

Moreover, in other embodiments, the stick body 211 and the connecting shaft 212 are rotationally connected, and the stick body 211 and the connecting shaft 212 are rotatable relative to each other, so that the first cutting knife 11 rotates relative to the second cutting knife 12 When moving, the frictional resistance of the first cutting knife 11 during movement can be reduced, thereby improving the stability of the cutting device 1 when cutting the towel 100 .

In addition, in some embodiments, a cutter fixing device is also provided. The cutter fixing device 3 is used to fix the above-mentioned cutting device 1. As shown in Figure 4, the cutter fixing device 3 includes: A bracket 31 and a limiting component 32. Among them, the first bracket 31 installs and fixes the first cutting knife 11 of the cutting device 1, and the limiting component 32 presses the second cutting knife 12 of the cutting device 1 and can force the second cutting knife 12 to be relative to the second cutting knife 12. One cutter 11 is arranged at an angle. At the same time, the limiting component 32 is also used to align the second blade 121 of the second cutting knife 12 with the first cutting edge of the first cutting knife 11 when the second cutting knife 12 and the first cutting knife 11 move relative to each other to the preset position. The blade portions 111 are staggered and fit together. Therefore, when cutting the soft towel 100, the cutting device 1 can A large shearing force is generated on the soft towel 100, so that the cutting device 1 can cut the soft towel 100 at one time. Therefore, it not only ensures the smoothness of the cross section of the soft towel 100 after being cut, but also facilitates the user to cut the soft towel 100. Get operations.

Specifically, as shown in FIG. 1 , in some embodiments, as shown in FIG. 4 , the limiting assembly 32 includes: a second bracket 321 and an extension 322 . Among them, the second bracket 321 presses the second cutting knife 12 , and the extension piece 322 is connected with the second cutting knife 12 and presses the first bracket 31 . Moreover, when in use, the second bracket 321 and the extension piece 322 can cooperate together to force the second cutting knife 12 to be tilted relative to the first cutting knife 11 .

In addition, it is worth mentioning that, as shown in FIG. 4 , the first bracket 31 includes: a first back plate 311 , a bottom edge 312 and a first front plate 313 . As shown in FIG. 4 , the first back plate 311 has a first top 3111 and a first bottom 3112 along a preset direction, and the bottom edge 312 is formed by the first bottom 3112 of the first back plate 311 along a direction perpendicular to the first back. The plate 311 is bent and extended in the direction of the first front plate 313 . At the same time, the first front plate 313 is bent and extended from the side of the bottom edge 312 away from the first back plate 311 toward the second cutting knife 12 . In addition, it is worth noting that, as shown in Figure 4, a first installation groove 314 is formed between the first back plate 311 and the first front plate 313. When the first cutting knife 11 is installed, the first cutting knife 11 can be It is detachably installed in the first installation groove 314, and at the same time, the first blade 111 of the first cutting blade 11 is protruded from the first installation groove 314. In addition, in other embodiments, as shown in FIGS. 3 and 4 , the first front plate 313 gradually extends obliquely toward the first back plate 311 from one side connected to the bottom edge 312 to the other side. Therefore, the side of the first front plate 313 away from the first back plate 311 is an inclined plane, so that the inclined plane can be used as a reference plane for contacting the extension member 322. Therefore, as shown in Figures 3 and 4, it is only necessary to The inclined surface of a front plate 313 completely fits the extension piece 322 of the second cutting blade 12 , so that the entire second cutting blade 12 is tilted relative to the first cutting blade 11 . It is easy to see from the above that since the first front plate 313 gradually extends obliquely toward the first back plate 311 from one side connected to the bottom edge 312 to the other side, the first front plate 313 has an inclined shape. The first front plate 313 can cooperate with the first back plate 311 to clamp the first cutting knife 1 by means of the inclined surface 3131 of the first front plate 313 .

At the same time, in order to further improve the fixing performance of the first bracket 31 to the first cutting knife 11, in some embodiments, the first bracket 31 further includes: a first locking piece, for example, as shown in Figure 4, the first locking piece The locking member can be a bolt 35, through which the first cutting knife 11 can be locked and fixed to the first front plate 313 and the first back plate 311 respectively. Of course, in other embodiments, the first locking Other locking components may also be used, and the type and structure of the locking components are not specifically limited in this embodiment.

In addition, by virtue of the fitting of the extension piece 322 to the first front plate 313, the second cutting blade 12 can be tilted relative to the first cutting blade 11 as a whole. In order to enable the second cutting blade 12 to be tilted relative to the first cutting blade 11, When the knife 11 moves, it always maintains an inclined state. As shown in Figure 4, the second bracket 321 is detachably provided on the first top 3111 of the first back plate 311, and the second bracket 321 includes: a second back plate 3211, top edge 3212 and second front panel 3213. The second back plate 3211 is detachably connected to the first back plate 311, and, as shown in FIG. 3, the second back plate 3211 has a second top along the preset direction. 32111 and the second bottom 32112, and the top edge 3212 is formed by bending and extending the second top 32111 of the second back plate 3211 in a direction perpendicular to the second back plate 3211. At the same time, the second front plate 3213 is formed by the top edge 3212 The side away from the second back plate 3211 is bent and extended in the direction of the first cutting knife 11. Finally, as shown in FIGS. 3 and 4, a second back plate 3211 and the second front plate 3213 are formed between the second back plate 3211 and the second front plate 3213. Mounting slot 3214. Therefore, in some embodiments, as shown in FIG. 4 , it is only necessary to dispose the second cutting blade 12 in the second mounting groove 3214, and at the same time, protrude the second blade 121 of the second cutting blade 12 from the second mounting groove 3214. Mounting slot 3214. In addition, as shown in FIGS. 3 and 4 , the second front plate 3213 gradually extends obliquely toward the second back plate 3211 from one side connected to the top edge 3212 to the other side, so that the second front plate 3213 moves away from the second back plate 3211 . One side of the top edge 3212 can resist the second cutting knife 12 . It is not difficult to see from this that with the pressure of the first front plate 313 on the second cutting knife 12 and the fitting of the extension piece 322 to the first front plate 313, the second cutting knife 12 can be moved in the direction relative to the first cutting knife. 11. Always maintain a tilted state when exercising. Moreover, in order to further improve the stability of the second front plate 3213 of the second bracket 321 when pressing the second cutting knife 12, the second bracket 321 also includes: a second locking piece, for example, as shown in Figure 4, The second locking member can be a rivet 45, through which the second back plate 3211 and the first back plate 311 can be locked and fixed, so that the second bracket 321 can be integrated with the first bracket 31. Of course, in other embodiments, the second locking member may also use other locking components, and the type and structure of the locking components are not specifically limited in this embodiment.

In addition, in other embodiments, as shown in FIG. 4 , the extension member 322 is provided at either end of the second cutting knife 12 along the length direction of the second cutting knife 12 , so that the second cutting knife 12 is relative to the first cutting knife 12 . While the knife 11 can be tilted, it can also increase the cutting range of the first cutting knife 11 and the second cutting knife 12 when cutting the towel 100, so that the extension 322 will not interfere with the first cutting knife 11 and the second cutting knife 100. The cutting knife 12 interferes with the cutting of the soft towel 100 . Moreover, the extension piece 322 is formed by an end of the second cutting blade 12 extending obliquely toward the direction of the first cutting blade 11 along the length direction, so that the extension piece 322 can be used as a part of the second cutting blade 12 , so that the second cutting blade 12 When moving relative to the first cutter 11, it is more stable.

In addition, in some embodiments, a cutting mechanism is also provided, as shown in Figures 7 and 10. The cutting mechanism includes: the cutting device 1 and the driving device 5 as described above.

As shown in Figures 7 and 10, the driving device 5 is used to receive a driving signal, and is used to drive the first cutting knife 11 and/or the second cutting knife 12 according to the received driving signal, so that the first cutting knife 11 and The second cutting knives 12 move relative to each other.

It is easy to see from the above that the driving device 5 can drive the first cutting knife 11 and the second cutting knife 12 to move in the direction of approaching each other according to the received driving signal, thereby realizing cutting of the towel 100 . Moreover, since the cutting direction of the first cutting knife 11 and the second cutting knife 12 on the soft towel 100 is relative to the soft towel 100, therefore, the first cutting knife 11 and the second cutting knife 12 are cutting the soft towel 100. When the soft towel 100 is not subjected to lateral resistance, the soft towel 100 will not gather to one side, thereby effectively improving the success rate of the cutting device 1 for cutting the soft towel 100 at one time, and when the soft towel 100 cannot be cut at one time, Since the first cutting knife 11 can move linearly away from the second cutting knife 12, it can effectively Prevent the cutting device 1 from getting stuck.

Specifically, as shown in FIGS. 8 and 9 , the first cutting blade 11 includes: a first head end 116 , a first tail end 112 disposed away from the first head end 116 , The first pivot portion 113 is between the tail ends 112 , and the first cutting knife 11 is rotatable relative to the second cutting knife 12 through the first pivot portion 113 .

In addition, in some embodiments, as shown in FIGS. 8 and 9 , the second cutter 12 includes: a second head end 126 , a second tail end 122 disposed away from the second head end 126 , and the second cutter 12 The second tail end 122 of 12 is provided with a second pivot part 125, and the second cutting knife 12 can rotate relative to the first cutting knife 11 through the second pivot part 125. Therefore, when the first cutting knife 11 and the second cutting knife 12 move toward each other, the first cutting knife 11 is used to connect the second head end 126 of the second cutting knife 12 with the first cutting knife 11 After the first head ends 116 are closed together, they will rotate toward the direction of the second cutter 12 , so that the first cutter 11 and the second cutter 12 can gradually close from the head ends of the two cutters toward the tail ends.

In addition, when the second head end 126 of the second cutting knife 12 and the first head end 116 of the first cutting knife 11 are brought together, in order to allow the first cutting knife 11 to rotate in the direction of the second cutting knife 12, as As shown in FIGS. 7 and 8 , the first head end 116 of the first cutting blade 11 is provided with a first clamping slot 114 , and the second head end 126 of the second cutting blade 12 is provided with a second clamping slot 123 . Moreover, along the preset direction, the length of the first slot 114 is greater than the length of the second slot 123 . In addition, as shown in Figures 7 and 9, the driving device 5 includes: a transmission component 51 and a driving assembly 52, and the transmission component 51 has a first limiting protrusion 511 embedded in the first card slot 114, a second card embedded in the The second limiting protrusion 512 is in the groove 123, and the second limiting protrusion 512 is slidable in the second clamping groove 123 along the preset direction. In addition, the driving component 52 is also electrically connected to the main control module 20 of the soft tissue box, and the driving component 52 is used to drive the transmission component 51 to linearly move in a preset direction.

It is not difficult to see from this that in application, as shown in FIGS. 7 to 10 , the driving component 52 can receive the first driving signal output by the main control module 20 , and when the driving component 52 receives the third driving signal output by the main control module 20 After receiving a driving signal, the driving assembly 52 can drive the transmission component 51 to move in the direction of the second cutting knife 12, and during the movement of the transmission component 51, as shown in Figures 8 and 9, it can first use the second limiter. The cooperation between the protrusion 512 and the second slot 123 allows the second cutting blade 12 as a whole to rotate in the direction of the first cutting blade 11 using the second pivoting part 125 as a fulcrum, and during the linear motion of the transmission component 51, due to The first clamping groove 114 has a longer length, so that the first limiting protrusion 511 at this time does not contact the groove wall of the first clamping groove 114, and only the second limiting protrusion 512 drives the second cutting edge. The knife 12 rotates toward the direction of the first cutting knife 11, and when the first limiting protrusion 511 offsets the groove wall of the first clamping groove 114, as shown in Figures 8 and 9, the second cutting knife 12 The head end 126 and the first head end 116 of the first cutting knife 11 have been closed. At this time, the transmission component 51 continues to move in the direction of the second cutting knife 12, with the help of the first limiting protrusion 511 and the first clamping groove 114. The abutment of the groove wall allows the first cutting knife 11 to rotate relative to the second cutting knife 12 with the first pivot portion 113 as a fulcrum driven by the transmission component 51, that is, the first head of the first cutting knife 11 The end 116 can move in a direction away from the second cutting knife 12, and the tail of the first cutting knife 11 The end 112 can move toward the direction of the second cutting knife 12 until the first tail end 112 of the first cutting knife 11 and the second tail end 122 of the second cutting knife 12 are closed, then the cutting of the soft towel can be completed.

In addition, in order to enable the driving assembly 52 to drive the transmission component 51 to linearly move in a preset direction, as shown in FIGS. 7 and 9 , the transmission component 51 has a toothed surface 513 along the preset direction, and the teeth corresponding to the transmission component 51 Surface 513 , the driving assembly 52 includes: a motor 521 electrically connected to the main control module 20 , and a gear 522 coaxially disposed with the main shaft of the motor 521 , and the gear 522 also meshes with the toothed surface 513 on the transmission component 51 . In application, the motor 521 can receive the first drive signal output by the main control module 20 , and after the motor 521 receives the first drive signal output by the main control module 20 , as shown in FIGS. 1 and 2 , the motor 521 The gear 522 can be driven to rotate, and when the gear 522 rotates, it can drive the transmission component 51 to linearly move in a preset direction by means of meshing with the toothed surface 513, so that the first cutting knife 11 and the second cutting knife 12 can be driven in the transmission direction. The components 51 move in opposite directions to each other.

Moreover, in other implementations, as shown in FIGS. 8 and 9 , the straight-line distance from the first head end 116 of the first cutting knife 11 to the first pivot part 113 is smaller than the distance from the first tail end 112 to the first pivot part. The linear distance of the first pivot portion 113 is that the first pivot portion 113 is disposed close to the first head end 116, thereby ensuring that when the first cutting knife 11 rotates in the direction of the first pivot portion 113 toward the second cutting knife 12, the first The linear range of the blade 111 from the first tail end 112 to the first pivot part 113 can be used to cut towels, thereby meeting the cutting needs of wider towels.

In addition, after the cutting device 1 completes cutting the soft towel 100, the first cutting knife 11 and the second cutting knife 12 of the cutting device 1 can realize a reset movement. As shown in Figure 10, in this embodiment The cutting mechanism also includes: a first detection module 6 and a second detection module 7 . Among them, the first detection module 6 and the second detection module 7 are arranged oppositely along the preset direction, and the first detection module 6 and the second detection module 7 are electrically connected to the main control module 20. At the same time, the transmission component 51 is also arranged on the third between a detection module 6 and a second detection module 7.

It is easy to see from the above that when the driving component 52 receives the first driving signal output by the main control module 20, the driving component 52 can drive the transmission component 51 to move linearly in the direction of the first detection module 6, so that the transmission at this time The component 51 can drive the first cutting knife 11 and the second cutting knife 12 to move toward each other, so that the first cutting knife 11 and the second cutting knife 12 can cut the soft towel 100 . When the first detection module 6 detects the transmission component 51, it means that the first cutting knife 11 and the second cutting knife 12 have completed cutting the soft towel 100. At this time, the main control module 20 can output the third signal to the driving assembly 52. and when the driving component 52 receives the second driving signal, the driving component 52 can drive the transmission component 51 to move linearly in the direction of the second detection module 7, so that the transmission component 51 at this time can drive the first cutting knife. 11 and the second cutting knife 12 move in the direction away from each other, thereby realizing the reset of the first cutting knife 11 and the second cutting knife 12, and when the second detection module 7 detects the transmission component 51, the first The cutting knife and the second cutting knife have returned to their positions, and the main control module 20 can turn off the driving assembly 52 at this time.

Moreover, it should be noted that in this embodiment, the first detection module 6 and the second detection module 7 can both use Hall elements, so that when the first detection module 6 or the second detection module 7 detects the transmission component 51 , can output a Hall signal to the main control module 20 , and the main control module 20 can perform different operations on the driving component 52 according to the received Hall signal output by the first detection module 6 or the second detection module 7 .

In addition, in some embodiments, as shown in FIG. 11 , the side of the first cutting knife 11 facing away from the second cutting knife 12 has a reference side 117 , and at the same time, the reference side 117 has a flat surface 1171 along the length direction of the first blade 111 . , an inclined surface 1172 connected to at least one side of the plane 1171 , and the inclined surface 1172 is formed by gradually extending obliquely in a direction close to the second cutting knife 12 from one side connected to the plane 1171 to the other side. However, in other embodiments, as shown in FIG. 11 , along the length direction of the first blade 111 , inclined surfaces 1172 are respectively provided on both sides of the plane 1171 , so that the plane 1171 and the inclined surface 1172 together constitute the reference side 117 .

In addition, corresponding to the flat surface 1171 of the first blade 11 and the inclined surfaces 1172 located on both sides of the flat surface 1171, as shown in FIG. 11, the driving device 5 includes: a sliding seat 53 and a driving assembly 54. The sliding base 53 is slidable along the length direction of the first cutting blade 11 and is used to contact the reference side 117 when sliding. Secondly, the driving component 54 is used to receive a driving signal, and when the driving component 54 receives the driving signal, the sliding seat 53 can be driven to slide along the length direction of the first cutting knife 11 according to the driving signal.

It is easy to see from this that in some embodiments, as shown in FIG. 1 , the right half of the first blade 111 of the first cutting knife 11 can be used as the first part, and at the same time, the left half of the first blade 111 can be used as the first part. part as part two. Therefore, when the driving assembly 54 slides the driving slide 53 along the length direction of the first blade 111 , that is, when the driving slide 53 slides from the right to the left first, as shown in FIG. 11 , the slide 53 can first use Cooperating with the inclined surface 1172 of the right half of the first cutting knife 11, the right half of the first cutting knife 11 is gradually lifted toward the direction of the second cutting knife 12, and when the sliding seat 53 slides to contact with the first cutting knife 12, When the flat surface 1171 of 11 abuts, as shown in Figure 11 , the end of the first part of the first blade 111 and the second blade 121 of the second cutting blade 12 can be brought together. At this time, the slide 53 is in the driving assembly. 54, by continuing to slide along the plane 1171, the first part of the first blade 111 can gradually close with the second blade 121. When the sliding seat 53 slides to a position beyond the center of the plane 1171, the weight of the first part of the first blade 111 is greater than the weight of the second part, causing the first part of the first blade 111 to move away from the second part. The cutting knife 12 moves in a direction, and the second part of the first blade 111 can move in a direction close to the second cutting knife 12, so that the second part of the first blade 111 can gradually close with the second blade, and The first part of the first blade 111 can be gradually separated from the second blade 12 . And when the slide seat 53 slides to the end of the left half of the plane 1171, the end of the second part of the first blade 111 and the second blade 121 of the first cutting knife 11 are closed, and the first blade The remaining parts of the first cutting blade 111 are separated from the second blade 121, and when the sliding seat 53 continues to slide and cooperates with the bevel 1172 of the left half of the first cutting blade 11, the left half of the first cutting blade 11 can be Gradually move away from the second cutting knife 12 until the sliding seat 53 slides out of the slope of the left half of the first cutting knife 11, so that the first cutting knife 11 returns to the right side. the initial position.

On the contrary, when the sliding seat 53 slides from the left to the right, as shown in Figure 11 , the sliding seat 53 can first cooperate with the inclined surface 1172 of the left half of the first cutting knife 11 to move the first cutting knife 11 The working half is gradually lifted toward the direction of the second cutting knife 12, and when the sliding seat 53 slides to contact the plane 1171 of the first cutting knife 11, as shown in Figure 11, the first blade can be The end of the second part of 111 is brought together with the second blade 121 of the second cutting knife 12. At this time, the slide 53 is driven by the driving assembly 54 and continues to slide along the plane 1171, so that the second blade 111 of the first blade 111 can be cut. The two parts can gradually close with the second blade 121 . When the sliding seat 53 slides to a position beyond the center of the plane 1171, the weight of the second part of the first blade 111 is greater than the weight of the first part, causing the second part of the first blade 111 to move away from the second part. The cutting knife 12 moves in the direction, and the first part of the first blade part 111 can move in the direction close to the second cutting knife 12, so that the first part of the first blade part 111 can gradually close with the second blade part 121, and the first part of the first blade part 111 can gradually close with the second blade part 121. The second part of the first blade 111 is gradually separated from the second blade 12 . And when the slide seat 53 slides to the end of the right half of the plane 1171, as shown in Figure 11, the end of the first part of the first blade 111 and the second blade 121 of the first cutting knife 11 are closed. , and the remaining parts of the first blade 111 are separated from the second blade 121, and when the sliding seat 53 continues to slide and cooperates with the bevel 1172 of the left half of the first cutting knife 11, the first cutting knife 11 can be The right half of the first cutter 11 gradually moves away from the second cutter 12 until the slide 53 slides out of the slope 1172 of the right half of the first cutter 11, so that the first cutter 11 returns to the original position on the left side. .

It is easy to see from this that by one reciprocal sliding of the slide seat 53, the first blade 111 of the first cutting blade 11 and the second blade 12 of the second cutting blade 12 can be closed twice, thereby achieving alignment. Cutting of two soft towels 100, and since the entire first cutting knife 11 cooperates with the second cutting knife 12 to cut the soft towel 100, the first blade 111 of the first cutting knife 11 is the first blade 111 along its length direction. One part and the second part can gradually close with the second blade 121 of the second cutter 12, similar to the principle of scissor cutting. Therefore, the first cutter 11 and the second cutter 12 can produce greater impact on the soft towel. The large shearing force enables the cutting mechanism of this embodiment to cut the towel in one go, thereby ensuring the smoothness of the cross section of the towel after cutting and making it convenient for the user to operate the towel box.

Moreover, as a preferred solution, as shown in FIG. 11 , the sliding seat 53 is also provided with a slot 531 , and the first cutting knife 11 is partially embedded in the slot 531 from the reference side 117 to the first blade 111 , and the slot 531 is inserted into the slot 531 . 531 has a contact portion 532 for contacting the reference side 117. At the same time, the side of the contact portion 532 that contacts the reference side 117 is an arc surface. The arc surface of the contact portion 532 can make the contact A point contact is formed between the portion 532 and the first cutting knife 11, thereby ensuring that the first cutting knife 11 can slide under the sliding seat 53, so that the first part and the second part of the first blade part 111 can contact the second part one after another.
