[0011] Beneficial effects The application provides a range-adjustable anti-fake label coating device, which has the following beneficial effects compared with the prior art. 1. When the slide block is blocked by the frame and cannot slide further, the connecting rod is at the center of the arc sleeve. Simultaneously, the gear on the side of the connecting rod slides to mesh with the main gear, causing the main gear to drive the gear below it to rotate synchronously. This causes the gear to drive the connecting rod fixedly connected to its side to rotate rapidly counterclockwise, causing the frame fixedly connected to the lower end of the connecting rod to rotate synchronously. This allows the coating cylinder to enter the arc sleeve and rotate rapidly upwards along the arc-shaped cavity of the arc sleeve. The centrifugal force generated by the rotation of the coating cylinder throws off the adhesive material adhering to it, removing any residual adhesive. This prevents residual adhesive from affecting subsequent adhesive adhesion when reapplying adhesive to the coating cylinder, thus avoiding problems with the coating material's adhesion. If the amount of adhesive varies too much, and the connecting rod slides into the groove, it can contact and attract the magnet, thus pushing the arc strip to slide along the groove. At the same time, the end of the arc strip can detach from the groove and extend from the end of the arc sleeve, thus avoiding interference with the sliding of the connecting rod. Then, when the coating cylinder slides to the end of the arc sleeve, it starts to reverse, causing the main gear to start to rotate clockwise, thereby driving the magnet connected to it to slide synchronously. At this time, the arc strip begins to slide back into the groove until the stop block contacts the end face of the arc sleeve, thus sealing the groove and preventing the adhesive in the arc sleeve from sliding out of the arc sleeve along the groove. At this time, the adhesive in the arc sleeve can slide along the arc surface inside the arc sleeve to the opening at the end of the arc sleeve, so as to facilitate the recycling and reuse of the adhesive. 2. When the user starts the machine, the auxiliary gear fixed at its shaft begins to rotate rapidly, causing the rack below it to slide. Due to the significant resistance of the spring connected to the rack, the rack drives the slide block to slide synchronously with it. At this time, the connecting rod in the slide block begins to slide on the frame, causing the coating cylinder below it to slide to the label surface and contact the label. During the sliding process, the coating cylinder rolls on the label surface, applying adhesive to the label. After the adhesive application is complete, the auxiliary gear drives the rack to continue sliding until the slide block reaches the desired position. At the end of the frame, the slide block is blocked by the frame and cannot continue to slide. At this time, the auxiliary gear continues to rotate, which can drive the rack connected below it to continue to slide. That is, the rack begins to compress the spring fixed to it, thus compressing the spring and providing a margin for the rack to slide, thereby avoiding interference with the rack's sliding. When starting in reverse, the damping rubber strip at the connection between the slide block and the frame can effectively prevent the slide block from sliding before it contacts the slide block. This allows the auxiliary gear to gradually drive the spring to slide to its reset position until the connecting block is attached to the slide block. At this time, the rack begins to push the slide block towards the rubber hopper to replenish the rubber hopper. 3. In the process of sliding the sliding seat towards the rubber bin, when the sliding seat slides to the screw thread segment at the end of the screw rod, at this time, the screw rod can rotate at a constant speed under the action of the sliding seat because the screw rod does not have a self-locking effect, so that the bevel gear A fixedly connected at the end thereof rotates synchronously, at this time, the bevel gear B meshingly connected below the bevel gear A starts to rotate at a constant speed, and drives the screw rod fixedly connected at the shaft center thereof to rotate synchronously, at this time, the joint threadedly connected on the screw rod starts to slide upwards at a constant speed, in the process of sliding, the coating cylinder slides synchronously above it, and in the process of sliding of the coating cylinder above it, the coating cylinder is immersed in the rubber in the rubber bin, so that the rubber re-attached on the coating cylinder.

DETAILED DESCRIPTION
[0019] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.
[0020] The specific implementation of the present application is described in detail below in combination with specific examples.
[0021] Please refer to Figures 1 to 3 For an embodiment of the present application, a range-adjustable anti-counterfeiting label coating device is provided, comprising a rack 101, an adjusting assembly and a transmission assembly, the rack 101 is fixedly connected with an arc sleeve 204 at the side, the arc sleeve 204 is provided with a connecting rod 201 at the shaft center, the arc surface on the inner side of the arc sleeve 204 is provided with a groove 205, and the connecting rod 201 penetrates into the arc sleeve 204 through the groove 205, the bottom end of the connecting rod 201 is fixedly connected with a frame 202, the frame 202 is rotatably connected with a coating cylinder 203 inside, and the coating cylinder 203 is located at the opening end of the arc sleeve 204, the two side walls of the groove 205 are slidingly connected with an arc strip 207, the arc strip 207 is used to prevent glue from splashing out, the end of the arc strip 207 close to the connecting rod 201 is fixedly connected with a magnet 206, and the magnet 206 is adsorbed on the connecting rod 201, the other end of the arc strip 207 is fixedly connected with a stop block 208; The adjusting assembly is used to adjust the relative position of the coating cylinder 203 on the rack 101; the transmission assembly is used to slidingly guide the sliding seat 209.
[0022] Specifically, the adjusting assembly comprises a sliding seat 209 and a glue coating assembly, the sliding seat 209 is slidingly connected on the rack 101, and the end of the connecting rod 201 is rotatably arranged in the sliding seat 209, one end of the connecting rod 201 is fixedly connected with a gear 301, and a main gear 302 is arranged above the gear 301, and the gear 301 is in meshing connection with the main gear 302 in the sliding process, the main gear 302 is fixedly connected on the output shaft of 303, and the 303 is fixedly connected with the rack 101; The glue coating assembly is used to attach glue on the coating cylinder 203.
[0023] In this embodiment of the invention, when the slide block 209 slides to the point where it is blocked by the frame 101 and cannot continue sliding, the connecting rod 201 is at the axis of the arc sleeve 204. At the same time, the gear 301 on the side of the connecting rod 201 slides synchronously to the meshing point with the main gear 302, so that the main gear 302 starts to drive the gear 301 meshing below it to rotate synchronously. Then, the gear 301 starts to drive the connecting rod 201 fixedly connected to its side to start to rotate counterclockwise rapidly, so that the frame 202 fixedly connected to the lower end of the connecting rod 201 starts to rotate synchronously. This causes the coating cylinder 203 to enter the arc sleeve 204 and rotate rapidly upward along the arc-shaped cavity of the arc sleeve 204. The centrifugal force generated by the rotation of the coating cylinder 203 throws off the adhesive attached to it, thereby removing the residual adhesive. This avoids the residual adhesive on the coating cylinder 203 affecting the subsequent adhesive adhesion and causing excessive differences in the amount of adhesive applied when re-applying adhesive. Simultaneously, as the connecting rod 201 slides into the groove 205, it can contact and attract the magnet 206, thereby pushing the arc strip 207 to begin sliding along the groove 205. At the same time, the end of the arc strip 207 can detach from the groove 205 and extend from the end of the arc sleeve 204, thus avoiding interference with the sliding of the connecting rod 201. Subsequently, when the coating cylinder 203 slides to the end of the arc sleeve 204, 303 starts to reverse, causing the main gear 302 to start rotating clockwise, thereby driving the magnet 206 connected to it to slide synchronously. At this time, the arc strip 207 begins to slide back into the groove 205 until the stop block 208 contacts the end face of the arc sleeve 204, thus sealing the groove 205 and preventing the adhesive in the arc sleeve 204 from sliding out of the arc sleeve 204 along the groove 205. At this time, the adhesive in the arc sleeve 204 can slide along the arc surface inside the arc sleeve 204 to the opening at the end of the arc sleeve 204, so as to facilitate the recycling and reuse of the adhesive.
[0024] Specifically, the transmission assembly includes a secondary gear 304, a rack 305, and a connecting assembly.

The connecting block 306 is in close contact with the baffle at the end of the slide 209. The reset component is used to slide the rack 305 back to its original position.
[0026] Specifically, the reset assembly comprises a spring 309, the spring 309 is sleeved on the guide rod 307, one end of the spring 309 is fixedly connected with the connecting block 306, and the other end of the spring 309 is fixedly connected with the stop head 308, and the stop head 308 is fixedly connected on the guide rod 307.
[0027] In the embodiment of the application, the user starts 303, so that the fixedly connected pinion 304 at the shaft center starts to rotate rapidly, thereby driving the meshing connected rack 305 below to start to slide, because the spring 309 connected on the rack 305 has a large resistance, the rack 305 can start to drive the sliding seat 209 to slide synchronously, then the connecting rod 201 arranged in the sliding seat 209 starts to slide on the rack 101, so that the coating cylinder 203 below slides to the upper surface of the label and contacts the label, so that in the sliding process of the coating cylinder 203, the coating cylinder 203 can roll on the upper surface of the label, thereby coating the adhesive on the label, when the adhesive coating is completed, the pinion 304 drives the meshing connected rack 305 to continue to slide, until the sliding seat 209 slides to the end of the rack 101, so as to be blocked by the rack 101 and cannot continue to slide, at this time, the continuous rotation of the pinion 304 can drive the meshing connected rack 305 below to continue to slide, that is, at this time, the rack 305 starts to compress the fixedly connected spring 309, so that the spring 309 is compressed, providing a margin for the sliding of the rack 305, thereby avoiding interference with the sliding of the rack 305, when 303 is reversely started, because the damping rubber strip is arranged at the connecting position of the sliding seat 209 and the rack 101, the sliding of the connecting block 306 before contacting the sliding seat 209 can be effectively avoided, so that the pinion 304 gradually drives the spring 309 to slide to reset, until the connecting block 306 is attached to the sliding seat 209, at this time, the rack 305 starts to drive the sliding seat 209 to slide towards the adhesive bin 406, so as to supplement the adhesive thereon.

[0029] Specifically, the drive assembly includes an adhesive hopper 406, which is disposed below the coating cylinder 203 and is slidably connected to the frame 101.

The connector 405 is threadedly connected to a lead screw 404, and the lead screw 404 is rotatably connected to the frame 101. A bevel gear B403 is fixedly connected to the top of the lead screw 404.
[0030] In this embodiment of the invention, during the sliding process of the slide block 209 toward the adhesive hopper 406, when the slide block 209 slides to the threaded section at the end of the screw 401, since the screw 401 does not have a self-locking effect, the screw 401 can rotate at a constant speed under the action of the slide block 209, thereby causing the bevel gear A402 fixedly connected to its end to rotate synchronously. At this time, the bevel gear B403 meshing below the bevel gear A402 begins to rotate at a constant speed, and drives the lead screw 404 fixedly connected at its shaft to rotate synchronously. At this time, the threaded joint 405 on the lead screw 404 begins to slide upward at a constant speed. During its sliding process, the coating cylinder 203 slides synchronously to its upper position. During the sliding process of the coating cylinder 203 to its upper position, the coating cylinder 203 is immersed in the adhesive in the adhesive hopper 406, thereby causing the adhesive to be re-adhere to the coating cylinder 203.
