The provision of the weight 2150 can effectively reduce the load on the drive structure 2120.

In the present embodiment, referring to fig. 1 and 10, the first base frame 2100 is provided with a first guide rod 2160 and a second guide rod 2170, the movable frame 2210 is slidably mounted on the first guide rod 2160, and the counterweight 2150 is slidably mounted on the second guide rod 2170. The first guide rod 2160 is provided for ensuring the vertical elevation of the movable frame 2210, and the second guide rod 2170 is provided for ensuring the vertical elevation of the weight 2150.

In this embodiment, the first guide rod 2160 is provided with a first limiting structure 2161, and the first limiting structure 2161 is used for limiting the end of the descending travel of the movable frame 2210; the second guide rod 2170 is provided with a second limit structure 2171, and the second guide rod 2170 is used for limiting the end of the descending stroke of the counterweight 2150.

Specifically, if the connection structure 2140 is a cable, the counterweight 2150 and the rotation shaft 2130 need not be provided, and only the rotation shaft 2130 needs to be provided above the movable frame 2210. When the driving structure 2120 drives the rotating shaft 2130 to rotate forward, the connecting structure 2140 can be driven to wind or unwind. But the cable has a higher power requirement for the drive structure 2120 and has a lower stability relative to the chain and a higher failure rate.

In this embodiment, the self-adhesive tape further comprises a bearing structure 2300, wherein the bearing structure 2300 is hinged to the first base frame 2100 and is arranged between the feeding device 1000 and the first buffer roller 2110, and the self-adhesive tape is partially wound around the bearing structure 2300; actuation of the carrier structure 2300 can signal actuation of the drive structure 2120.

When support arm 2310 rotates about a hinge with first pedestal 2100, an action signal can be sent to drive structure 2120 to rotate clockwise or counterclockwise.

It will be appreciated that when the self-adhesive tape is being wound normally, as shown in figure 2, the transfer of the self-adhesive tape will lift the third roller bar 2320, holding the support arm 2310 in a horizontal position. When the winding bar is replaced, the third roller 2320 drops as the self-adhesive tape is not tensioned, causing the support arm 2310 to rotate about the hinge with the first pedestal 2100. To avoid the weight of the third roller 2320 being fully supported by the self-adhesive tape, an elastic member 2330 is connected between the second end of the support arm 2310 and the first pedestal 2100; the elastic member 2330 may be a spring or an elastic string. The elastic member 2330 is insufficient to maintain the support arm 2310 in the horizontal position, but the elastic member 2330 may prevent the support arm 2310 from rotating too fast around the hinge with the first pedestal 2100.

It is contemplated that the range of rotation of support arm 2310 is limited due to the presence of trigger structure 2180. The first switch and the second switch may be a touch switch or a photo switch.

It should be appreciated that the delay relay is required to be disposed at the first switch and the second switch, that is, after the driving structure 2120 acts, the same set time can be acted all the time, so as to ensure that the lifting position is consistent each time, and further ensure that the movable frame 2210 can be automatically reset to the same position each time.

In this embodiment, the triggering mechanism 2180 may also be telescopic, such as a cylinder without air supply, the fixed end of the cylinder is connected to the first pedestal 2100, and the movable end of the cylinder is hinged to the supporting arm 2310; when the movable end of the trigger mechanism 2180 is extended, the trigger actuation mechanism 2120 rotates clockwise/counterclockwise; when the movable end of the trigger mechanism 2180 retracts, the trigger actuation mechanism 2120 rotates counterclockwise/clockwise.

It is conceivable that the two feed roll bars 3200 may be disposed at intervals in the horizontal direction or disposed at intervals in the oblique direction, that is, only two or more feed roll bars 3200 are required to supply the film roll, and as for the position arrangement of the feed roll bars 3200, the placement may be performed according to the actual design. For example, if it is convenient to reduce the space occupation of the feed roll bars 3200, two feed roll bars 3200 spaced apart in the vertical direction are more commonly used; if the film roll on the feed roll bar 3200 is replaced conveniently, the two feed roll bars 3200 can be arranged at intervals along the horizontal direction, so that the two feed roll bars 3200 are located at the same height, and the film roll is convenient to disassemble and assemble.

Referring to fig. 1 and 2, the first pressing roller 3110 and the second pressing roller 3120 in the present embodiment are also disposed at intervals in the vertical direction. It is conceivable that the space occupation can be effectively reduced by arranging the first pressing roller bar 3110 and the second pressing roller bar 3120 at intervals in the vertical direction; in addition, since the self-adhesive tape and the film must pass between the first pressing roller 3110 and the second pressing roller 3120, the first pressing roller 3110 and the second pressing roller 3120 are disposed to be spaced apart in the vertical direction, the self-adhesive tape and the film can be wound around the second pressing roller 3120 without being detached from the second pressing roller 3120 when the tension of the self-adhesive tape and/or the film is lowered. If the first pressing roller 3110 and the second pressing roller 3120 are disposed at intervals in the horizontal direction, the self-adhesive tape and/or film is easily detached from the second pressing roller 3120 when the tension of the self-adhesive tape and/or film is lowered.

In some embodiments of the present invention, the first driving device 3300 that drives the first squeeze roller 3110 to press against the second squeeze roller 3120 may be a hydraulic cylinder, or a servo motor. First, the first and second squeeze rolls 3110 and 3120 should be spaced apart such that a space is provided between the first and second squeeze rolls 3110 and 3120, thereby facilitating the placement of the self-adhesive tape and the film, and the first squeeze roll 3110 is driven to be pressed against the second squeeze roll 3120 after both the self-adhesive tape and the film pass between the first and second squeeze rolls 3110 and 3120.

In this embodiment, the second base frame 3100 is provided with a roller rail 3130 disposed along a vertical direction, the first squeeze roller 3110 is slidably mounted on the roller rail 3130, and the first driving device 3300 is used for driving the first squeeze roller 3110 to lift along the roller rail 3130. Specifically, as can be seen from the above, the first pressing roller 3110 and the second pressing roller 3120 are disposed at intervals in the vertical direction, and thus the length extending direction of the roller slide 3130 is the vertical direction. Referring to fig. 1 and 11, a connector 3111 is sleeved at an end of a first squeeze roller 3110, and the connector 3111 is partially embedded in a roller slide 3130 and is slidable along the roller slide 3130; the first driving device 3300 is connected to the connector 3111.

In some embodiments of the present invention, two roller slide rails 3130 are provided and are respectively disposed at two longitudinal ends of the first squeeze roller 3110, and two connectors 3111 are disposed at two longitudinal ends of the first squeeze roller 3110, so that two first driving devices 3300 are also disposed, and two first driving devices 3300 are mounted on the second base frame 3100. By driving both ends of the first pressing roller 3110 in the longitudinal direction by the two first driving means 3300 to simultaneously operate, the first pressing roller 3110 and the second pressing roller 3120 can be better attached, thereby ensuring that no air bubbles exist between the self-adhesive tape and the film.

It is conceivable that the first press roll 3110 and the second press roll 3120 must be arranged in parallel, i.e. the central axes of the first press roll 3110 and the second press roll 3120 must be parallel in order to allow a better fit of the self-adhesive tape and the film.

It should be appreciated that neither the first extrusion roller 3110 nor the second extrusion roller 3120 is connected with a power device for driving the same, because the finished product self-adhesive tape after the self-adhesive tape and the film are attached can be wound by the winding rod, and the winding rod is connected with a power device for driving the same, so that the finished product self-adhesive tape is driven to move by the winding rod, and the finished product self-adhesive tape is moved, and the self-adhesive tape and the film are necessarily pulled to move, and neither the first extrusion roller 3110 nor the second extrusion roller 3120 is connected with a power device for driving the same to rotate.

In this embodiment, the feed roll bar 3200 is detachably mounted to the second base frame 3100. Specifically, as can be seen from the above, the feed roller rod 3200 is provided with a plurality of feed roller rods, and two feed roller rods are generally provided; the film rolls are sleeved on the feeding roller bars 3200, the film rolls of the two feeding roller bars 3200 alternately feed between the first extrusion roller bar 3110 and the second extrusion roller bar 3120, and the switching of the feeding roller bars 3200 can be manually or automatically switched. In this embodiment, the feeding roller lever 3200 is manually switched, so the feeding roller lever 3200 needs to be detachably mounted on the second base frame 3100, so that the switching of the feeding roller lever 3200 is facilitated.

In this embodiment, the second base frame 3100 is provided with a clamping groove 3140, and the feeding roller rod 3200 is movably mounted in the clamping groove 3140; still include the locating part, the locating part is installed in second bed frame 3100, and in the part extends to draw-in groove 3140, the locating part is used for carrying out the position fixing to feed roller pole 3200. Specifically, referring to fig. 1 and 12, the locking groove 3140 is open at one side, and when the end of the feed roller lever 3200 is installed in the locking groove 3140, the stopper can effectively prevent the feed roller lever 3200 from being separated from the locking groove 3140, thereby fixing the position of the feed roller lever 3200. The second base frame 3100 is provided with two clamping grooves 3140, and two ends of the feed roller rod 3200 are respectively arranged in the two clamping grooves 3140; therefore, two limiting pieces are also arranged, and the two limiting pieces are respectively used for fixing the positions of the two ends of the feed roller rod 3200.

In the present embodiment, a slot wall at one side of the slot 3140 is provided with a limiting hole 3141, and the limiting member is disposed in the limiting hole 3141 in a penetrating manner. Specifically, referring to fig. 4, the limiting member is a pin, and the pin is inserted into the limiting hole 3141 to block the feed roller rod 3200 from being separated from the clamping groove 3140.

It is conceivable that the fixing of the position of the feed roller rod 3200 is achieved by means of a latch, and different manners may be provided according to the position of the limiting hole 3141, for example, if the position of the limiting hole 3141 is set relatively close to the opening side of the clamping groove 3140, the limiting member only plays a role in limiting the feed roller rod 3200, and the feed roller rod 3200 can still rotate around its own axis; if the position of the limiting hole 3141 is set at a position overlapping with the central position of the feed roller rod 3200 installed in the clamping groove 3140, and the limiting piece is replaced by a bolt, the limiting hole 3141 is set as a threaded hole, the limiting piece is abutted against the surface of the feed roller rod 3200, so that the feed roller rod 3200 is limited to rotate around the axis of the feed roller rod.

It should be appreciated that, since the feed roller rod 3200 needs to be sleeved with the film roll, and the film roll needs to be unwound, at least one of the feed roller rod 3200 and the film roll can rotate around its own axis, for example, the film roll is sleeved on the feed roller rod 3200 but is in transmission connection with the feed roller rod 3200 through a key, etc., so that the feed roller rod 3200 needs to be rotatably mounted on the second base frame 3100 around its own axis; if the film roll is sleeved on the feed roller rod 3200 but can rotate relative to the feed roller rod 3200, the feed roller rod 3200 can be mounted on the second base frame 3100 in a manner of not rotating around the axis of the feed roller rod.

It is conceivable that the feed roll bar 3200 should be provided with a limiting structure for limiting the film roll, and the limiting structure should be capable of limiting the film roll to slide along the length direction of the feed roll bar 3200 during unreeling.

In this embodiment, the limiting member is not limited to a bolt or a bolt, but may be a structure such as an elastic stop block disposed on the frame, that is, a specific limiting member may be flexibly disposed.

In this embodiment, two radially protruding baffle rings 3210 are disposed at the end of the feed roller rod 3200, the two baffle rings 3210 are disposed at intervals along the length direction of the feed roller rod 3200, and an embedding section 3211 is formed between the two baffle rings 3210; the embedded segment 3211 is mounted in the card slot 3140. Specifically, referring to fig. 12, the length of the insertion section 3211 should be equal to the thickness of the locking groove 3140 so that the feed roller lever 3200 cannot slide in the length direction of the feed roller lever 3200 with respect to the second base frame 3100 after the insertion section is locked into the locking groove 3140.

When the feed roller rod 3200 needs to be disassembled, the feed roller rod 3200 can be taken out from the opening side of the clamping groove 3140 by directly disassembling the limiting piece, and the disassembly and assembly mode is simple and efficient and has low manufacturing cost.

In this embodiment, referring to fig. 12, the apparatus further includes a second driving device 3400, the second driving device 3400 is mounted on the second base frame 3100, and an output end of the second driving device 3400 is in transmission connection with the feed roller rod 3200. Specifically, each feed roller rod 3200 in this embodiment is connected to a second driving device 3400, where the second driving device 3400 is typically a motor, and the second driving device 3400 is used to drive the feed roller rod 3200 to rotate around its own axis. In this embodiment, a film roll is sleeved on the feed roller rod 3200 and is in transmission connection with the feed roller rod 3200 through a key and other modes, the feed roller rod 3200 is rotatably installed on the second base frame 3100 around the axis of the feed roller rod 3200, and a second driving device 3400 is provided for driving to adjust the rotation speed of the feed roller rod 3200. The self-adhesive tape and the film need be rolled up after the cost self-adhesive tape is formed through laminating, and the rolling rod needs to be replaced when the film is rolled up, and the finished product self-adhesive tape is not rolled up in the process of replacing the rolling rod, so that the self-adhesive tape and the film can fall down, the rotating speed of the feeding roller rod 3200 needs to be properly reduced at the moment, the film is prevented from being too much to cause the film to be in contact with the ground, and the second driving device 3400 is arranged to adjust the rotating speed of the feeding roller rod 3200 around the axis of the second driving device.

In the present embodiment, the output end of the second driving device 3400 is provided with a first gear 3410, and the end of the feed roll bar 3200 is provided with a second gear 3220; and further comprises a third gear 3150, the third gear 3150 is mounted on the second base frame 3100, and the first gear 3410 is in transmission connection with the second gear 3220 through the third gear 3150. Specifically, referring to fig. 12, the first gear 3410 and the second gear 3220 are connected by the third gear 3150 as an intermediate gear, and the third gear 3150 can function as one differential; that is, if the first gear 3410 is smaller, the third gear 3150 is larger, and the provision of the third gear 3150 can effectively reduce the rotational speed of the second gear 3220; in addition, since the feed roller bar 3200 is detachably mounted on the second base frame 3100, if the second gear 3220 is directly meshed with the first gear 3410, the second gear 3220 or the first gear 3410 is easily worn during frequent assembly and disassembly, and this situation can be effectively alleviated by the third gear 3150.

In this embodiment, the second base frame 3100 is further provided with a plurality of intermediate shafts 3160, the intermediate shafts 3160 are disposed between the second pressing roller 3120 and the feeding roller 3200, and the film portion supplied from the feeding roller 3200 is wound around the intermediate shafts 3160. Specifically, referring to fig. 4, a plurality of intermediate shafts 3160 are provided, and a plurality of intermediate shafts 3160 are provided in a staggered manner, and the purpose of the plurality of intermediate shafts 3160 is to tension the film, and also to change the conveying direction of the film, that is, the angle at which the film enters the first pressing roller 3110 and the second pressing roller 3120, better.

According to the film laminating device 3000 provided by the embodiment of the invention, at least two feeding roller rods 3200 are arranged, and films are alternately supplied through the two feeding roller rods 3200, so that continuous lamination of a self-adhesive tape and the films can be ensured, and the laminating production efficiency is greatly improved; the self-adhesive tape and the film can be fed and attached through automatic operation, manual participation is not needed, and labor cost is reduced.

The winding device 4000 of the embodiment of the invention includes a third base frame 4100 and a turntable 4200 mounted on the third base frame 4100, wherein the turntable 4200 is rotatably mounted on the third base frame 4100 around its own axis. A through hole is arranged on the third base frame 4100, a plurality of bearings are arranged on the wall of the through hole, and the bearings are uniformly arranged at intervals around the circumference; the turntable 4200 is installed in the through hole, and an outer circumferential wall of the turntable 4200 is in contact with the plurality of bearings, so that the turntable 4200 is mounted to the third base frame 4100 and can rotate around its central axis. Referring to fig. 5, one end of the rotary table 4200 is provided with a ring of external gears 4230, the external gears 4230 are engaged with a driving gear 4160, the driving gear 4160 is connected to a third driving device 4161 for driving rotation thereof, and the third driving device 4161 is typically a motor. The diameter of the driving gear 4160 is much larger than that of the driving gear 4160, so that the third driving device 4161 drives the driving gear 4160 to rotate rapidly, and can drive the turntable 4200 to rotate slowly. If a suitable rotational speed of the dial 4200 is desired, this may be achieved by adjusting the rotational speed of the third drive device 4161, or by adjusting the gear ratio of the external gear 4230 to the drive gear 4160.

In this embodiment, referring to fig. 5 to 7, two winding rods are mounted on the turntable 4200, and the two winding rods are respectively mounted on two opposite sides of the turntable 4200, and a winding drum is generally sleeved on the winding rods and is used for winding the self-adhesive tape. The turntable 4200 is rotated one hundred eighty degrees at a time to achieve the positional exchange of the two winding bars.

It is conceivable that three or four winding bars may be provided, but the number of winding bars is not as high as possible, but generally two winding bars are sufficient; however, if three or four winding bars are provided, the angle of each rotation of the turntable 4200 needs to be adjusted.

It is to be appreciated that only one winding rod at a time performs the winding of the self-adhesive tape. For ease of understanding, the first winding lever 4210 and the second winding lever 4220 are described herein. If the first winding rod 4210 winds the self-adhesive tape, the second winding rod 4220 is in a standby state; when the first winding bar 4210 winds the self-adhesive tape of a sufficient length, the first winding bar 4210 and the second winding bar 4220 exchange positions, the second winding bar 4220 winds the self-adhesive tape, simultaneously, the reel on which the self-adhesive tape has been wound on the first winding bar 4210 is removed, and a new reel is sleeved on the first winding bar 4210 again. The replacement winding drum can be replaced manually or by a mechanical arm, and can be selected according to actual conditions.

From the above, the winding rod is provided with a winding position and a winding position, the winding rod at the winding position is used for winding the self-adhesive tape, the winding rod at the winding position is used for replacing the winding drum, and the two winding rods are used for winding alternately.

In this embodiment, the cutting mechanism 4300 is configured to cut off the self-adhesive tape between the two winding rods after the two winding rods are exchanged, the first pressing assembly 4400 is configured to press the first end of the cut self-adhesive tape against the winding rod located at the winding position, and the second pressing assembly 4500 is configured to press the second end of the cut self-adhesive tape against the winding rod located at the winding position. When the self-adhesive tape between the two winding rods is cut off, the two winding rods are already exchanged in position at the moment, the sleeve on the winding rod at the winding position is not used for winding the self-adhesive tape, and the end part of the self-adhesive tape is pressed on the winding rod at the winding position through the first pressing component 4400, so that the continuous winding of the winding rod at the subsequent winding position is facilitated. Correspondingly, when the self-adhesive tape between the two winding rods is cut off, the sleeve on the winding rod at the reel replacing position winds enough self-adhesive tape, the end part of the self-adhesive tape is pressed on the winding rod at the reel replacing position through the second pressing component 4500, the wound winding drum can be ensured, and the self-adhesive tape is not easy to fall off from the winding drum.

The existing self-adhesive tape winding is basically provided with only one winding rod, then the winding rod is cut and replaced by manually judging the winding length, the conveying speed of the self-adhesive tape is required to be reduced in the process of replacing the winding, meanwhile, certain errors exist in the manually judged winding length, and the winding device 4000 of the embodiment ensures that the conveying speed of the self-adhesive tape is not required to be reduced in the process of replacing the winding drum by arranging two winding rods capable of being automatically switched; the cutting structure 4300 is arranged to automatically cut the self-adhesive tape, and the self-adhesive tape can automatically switch the winding rod after the winding rod at the winding position is wound, so that the manual participation is reduced, the production efficiency is greatly improved, and the labor cost is reduced; the first compression component 4400 and the second compression component 4500 are arranged to compress the end parts of the self-adhesive tapes on the two winding rods respectively, so that the winding quality is guaranteed.

In the present embodiment, the first pressing assembly 4400 includes a first pressing lever 4430, a first driving piece 4410 and a first swing arm 4420, a first end of the first swing arm 4420 is hinged to the third base frame 4100, and the first pressing lever 4430 is mounted to a second end of the first swing arm 4420; the first driving member 4410 is configured to drive the first swing arm 4420 to rotate around the hinge with the third base frame 4100, so as to drive the first pressing rod 4430 to move towards the winding rod. Specifically, referring to fig. 6 to 8, the first pressing assembly 4400 further includes a first rotating shaft 4460, the first rotating shaft 4460 is rotatably mounted to the third base frame 4100 about its own axis, and a first end of the first swing arm 4420 is connected to the first rotating shaft 4460; the two first swing arms 4420 are provided, the two first swing arms 4420 are arranged at intervals along the length direction of the first rotating shaft 4460, and two ends of the first pressing rod 4430 are respectively connected to the two first swing arms 4420. The first pressing rod 4430 is used for tensioning the self-adhesive tape, and after the two winding rods are subjected to position exchange, the first pressing component 4400 moves towards the winding rod located at the winding position, so that the self-adhesive tape is tensioned, and the cutting structure 4300 is convenient to cut off the self-adhesive tape.

In some embodiments of the present invention, the first driving member 4410 is a telescopic cylinder, the fixed end of the first driving member 4410 is hinged to the third base frame 4100, and the movable end of the first driving member 4410 is hinged to the middle of the first swing arm 4420. The first driving pieces 4410 are provided in two, and the two first driving pieces 4410 are connected to the two first swing arms 4420, respectively. The movable end of the first driving member 4410 extends or retracts to drive the first swing arm 4420 to move, thereby driving the first rotating shaft 4460 to rotate.

It should be understood that the first swing arm 4420 and the first rotating shaft 4460 may be omitted, and the first pressing rod 4430 may be directly driven to move toward the winding rod by the first driving member 4410, but in order to better adapt to the arrangement of the winding rod and the rotating disc 4200, the first pressing rod 4430 is driven to approach the winding rod by the first swing arm 4420, so as to achieve better tensioning effect on the self-adhesive tape.

It should be noted that when the movable end of the first driver 4410 is retracted, the first compression assembly 4400 should be positioned entirely below the turntable 4200 to avoid obstruction to the exchange of positions of the two winding bars.

In this embodiment, the cutting structure 4300 is mounted to the first compression assembly 4400. Specifically, referring to fig. 8, the first swing arm 4420 is provided with a first slide rail 4440, and the length extension direction of the first slide rail 4440 is parallel to the length extension direction of the winding rod; the cutting structure 4300 is slidably mounted to the first slide rail 4440. Since the first slide rail 4440 is connected to the first swing arm 4420, the first slide rail 4440 and the cutting structure 4300 move synchronously when the first swing arm 4420 rotates.

In this embodiment, the first pressing assembly 4400 further includes a second pressing rod 4450, the second pressing rod 4450 is mounted on the second end of the first swing arm 4420, and the second pressing rod 4450 is spaced from the first pressing rod 4430; the cutting structure 4300 includes a cutting blade 4310, the cutting blade 4310 extending between the first compression bar 4430 and the second compression bar 4450. Specifically, referring to fig. 6 to 8, when the first pressing member 4400 moves to a contact position with the winding rod positioned at the winding position, the second pressing rod 4450 is positioned above the first pressing rod 4430, and both the first pressing rod 4430 and the second pressing rod 4450 are in contact with the winding rod through the self-adhesive tape, so that the self-adhesive tape between the first pressing rod 4430 and the second pressing rod 4450 is necessarily tensioned, and thus the cutting blade 4310 is disposed to extend between the first pressing rod 4430 and the second pressing rod 4450, so that the tensioned self-adhesive tape can be cut very smoothly.

In some embodiments of the present invention, the second end of the first swing arm 4420 is provided with a mounting hole 4421, and two ends of the second pressing rod 4450 are respectively mounted in the mounting holes 4421 of the two first swing arms 4420; the end of the second pressing rod 4450 is slidable along the mounting hole 4421; the first swing arm 4420 is further provided with a telescopic mechanism for driving the second pressing rod 4450 to slide along the mounting hole 4421. Specifically, referring to fig. 8, the mounting hole 4421 is a bar-shaped hole, and the telescopic mechanism is used to drive the second pressing rod 4450 to slide along the bar-shaped hole. The mounting hole 4421 is provided as a strip-shaped hole and the function of the telescopic mechanism is to enable the end of the self-adhesive tape to be tightly attached to the winding drum of the winding rod. When the cutting structure 4300 cuts the self-adhesive tape between the first compression rod 4430 and the second compression rod 4450, the telescopic mechanism stretches out to drive the second compression rod 4450 to slide along the strip-shaped hole, so that the second compression rod 4450 can slide along the surface of the winding rod for a small distance, and at the moment, since the self-adhesive tape between the first compression rod 4430 and the second compression rod 4450 is cut off, the small distance for the second compression rod 4450 to slide along the surface of the winding rod is equivalent to rolling the end part of the self-adhesive tape once, so that the end part of the self-adhesive tape is tightly attached to a winding drum sleeved on the winding rod.

In this embodiment, the second pressing assembly 4500 includes a second rotating shaft 4540, a second driving member 4510, a second swing arm 4520 and a third pressing rod 4530, the second rotating shaft 4540 is rotatably mounted on the third base frame 4100 around its own axis, the second rotating shaft 4540 is penetrating through the middle of the second swing arm 4520, the second driving member 4510 is connected with the first end of the second swing arm 4520, and the third pressing rod 4530 is mounted on the second end of the second swing arm 4520; the second driving member 4510 is configured to drive the second swing arm 4520 to rotate about the second rotation axis 4540, so as to drive the third pressing lever 4530 to contact with the winding lever located at the reel change position. Specifically, referring to fig. 5 to 7, the second pressing assembly 4500 is located above the first pressing assembly 4400 and also located above the turntable 4200, and after the third pressing rod 4530 contacts the winding rod located at the reel change position, the end of the self-adhesive tape wound on the winding rod located at the reel change position can be adhered to the winding rod. The two second swing arms 4520 are provided, the two second swing arms 4520 are arranged at intervals along the length direction of the second rotating shaft 4540, and two ends of the third pressing rod 4530 are respectively connected to the two second swing arms 4520. The second driving member 4510 has a structure such as a telescopic cylinder, the fixed end of the second driving member 4510 is hinged to the third base frame 4100, the telescopic end of the second driving member 4510 is hinged to the second swing arms 4520, two second driving members 4510 are provided, and the two second driving members 4510 are respectively connected to the two second swing arms 4520.

It is contemplated that the second pressing assembly 4500 may be configured to directly drive the third pressing bar 4530 to move to a contact position with the winding bar through the second driving member 4510 without providing the second swing arm 4520 and the second rotation shaft 4540.

In this embodiment, a third compression assembly 4600 is also included, the third compression assembly 4600 cooperating with the first compression assembly 4400 to tension the self-adhesive tape on the surface of the winding rod in the winding position to facilitate the cutting structure 4300 to sever the self-adhesive tape. Specifically, referring to fig. 6 and 7, the third pressing assembly 4600 includes a third driving member 4610 and a fourth pressing rod 4620, the third base frame 4100 is provided with a second sliding rail 4110, the fourth pressing rod 4620 is slidably mounted on the second sliding rail 4110, and the third driving member 4610 is configured to drive the fourth pressing rod 4620 to slide along the second sliding rail 4110; the fourth pressing bar 4620 can contact the winding bar at the winding position when sliding to the stroke end position. The purpose of the third hold down assembly 4600 is to facilitate the rolling of the self-adhesive tape on a new roll. Taking fig. 7 as an example, the third pressing rod 4530 has a diameter substantially larger than that of the first and second pressing rods 4430 and 4450, and the third and second pressing rods 4530 and 4450 may be regarded as being respectively abutted against opposite sides of the winding rod. When the two winding rods complete the position exchange, the third pressing assembly 4600 acts first, and the first pressing assembly 4400 acts later.

It is conceivable that if the third pressing assembly 4600 is not provided and only the first pressing assembly 4400 and the second pressing assembly 4500 are provided, only the first pressing assembly 4400 contacts the winding shaft at the winding position after the two winding shafts are completely exchanged. It can be seen from fig. 7 that the winding of the self-adhesive tape is performed from the bottom of the winding rod upwards, i.e. counter-clockwise as shown in fig. 7. When the second pressing rod 4450 pushes the end part of the self-adhesive tape to be tightly attached to the winding drum, the winding rod at the winding position starts to wind, but the self-adhesive tape does not have strong viscosity, under the condition that the third pressing component 4600 is not provided, the end part of the self-adhesive tape is easily separated from the winding rod due to the weight of the self-adhesive tape, and therefore the third pressing component 4600 is arranged, so that the winding rod can wind the self-adhesive tape more stably.

In this embodiment, the turntable 4200 is provided with a mounting bar 4120, the mounting bar 4120 being sleeved with a gear set 4130; the two winding rods are a first winding rod 4210 and a second winding rod 4220 respectively, a first driving device 4211 and a second driving device 4221 are installed on the third base frame 4100, the first driving device 4211 is in transmission connection with the first winding rod 4210 through a gear set 4130, and the second driving device 4221 is in transmission connection with the second winding rod 4220 through the gear set 4130. Specifically, referring to fig. 5, a mounting rod 4120 is disposed at a central position of the turntable 4200, and a gear set 4130 is sleeved on the mounting rod 4120 and is rotatable about the mounting rod 4120.

The thimble 4171 can prop against the end part of the winding rod positioned at the winding position, so that the shaking of the winding rod in the winding process is reduced. Referring to fig. 1 and 5, when the winding rod is located at the winding position, the ejector pin 4171 is aligned with the winding rod located at the winding position, and after the rotation of the turntable 4200 is stopped, the fourth driving member 4170 drives the ejector pin 4171 to tightly push the winding rod located at the winding position, and the rotation of the winding rod is more stable through the tightly push of the ejector pin 4171, so as to effectively improve the winding quality.

Referring to fig. 6 and 7, the automatic switching process of the two winding rods in this embodiment is as follows (taking fig. 6 as an example, the winding rod at the winding position is defined as a first winding rod 4210, and the winding rod at the winding position is defined as a second winding rod 4220):

s1, a first driving device 4211 drives a first winding rod 4210 to continuously wind, and a second winding rod 4220 is kept motionless;

s2, after the first driving device 4211 drives the first winding rod 4210 to rotate for a set number of turns or for a set period of time, the first driving device 4211 reduces the rotation speed, the third driving device 4161 drives the rotary table 4200 to rotate, when the rotary table 4200 rotates for one hundred eighty degrees, the first winding rod 4210 stops rotating, at this time, the first winding rod 4210 rotates to a winding position, and the second winding rod 4220 rotates to a winding position, namely, the position of FIG. 7;

s3, the third pressing component 4600 is operated to enable the fourth pressing rod 4620 to slide along the second sliding rail 4110 to an end position of the stroke, so that the fourth pressing rod 4620 is abutted against the second rolling rod 4220;

s4, the first pressing component 4400 acts to enable the first pressing rod 4430 and the second pressing rod 4450 to abut against the second winding rod 4220; the second compression assembly 4500 is actuated to bring the third compression bar 4530 into abutment with the first wrap bar 4210; the final position is shown in fig. 7;

S5, sliding the cutting structure 4300 along the first sliding rail 4440 to cut the self-adhesive tape;

s6, the telescopic mechanism acts to drive the second compression rod 4450 to slide along the mounting hole 4421 so that one end of the self-adhesive tape at the cut-off position is tightly attached to the second winding rod 4220;

s7, the first driving device 4211 acts to drive the first winding rod 4210 to rotate; the second driving device 4221 acts to drive the second winding rod 4220 to rotate;
