Description

Technical Field

[0001] This invention belongs to the field of anti-counterfeiting label production technology, and in particular relates to an anti-counterfeiting label embossing device. Background Technology

[0002] Embossed anti-counterfeiting labels are three-dimensional labels formed on the surface of products through molding processes. They typically have a raised or recessed tactile feel, making them difficult to replicate and thus achieving an anti-counterfeiting effect. These labels not only serve as brand identifiers but also enhance the product's aesthetics and anti-counterfeiting capabilities. However, during the embossing process on leather, the relatively soft surface of the leather can easily cause the label to deform and become blurred. Therefore, a structure that can tighten the leather during embossing is proposed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an anti-counterfeiting label embossing device, which solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anti-counterfeiting label embossing device, comprising a frame and a positioning component for tensioning leather; the positioning component comprises a roller A, a secondary gear, a guide rod, a connecting ear, a frame, a roller B, and a main gear; two rollers A are symmetrically rotatably connected to the bottom of the frame; the secondary gear is fixedly connected to roller A; two guide rods are symmetrically fixedly connected to the frame; the connecting ear is slidably connected to the guide rod; the frame is fixedly connected to the connecting ear; two rollers B are symmetrically rotatably connected to the frame; the main gear is fixedly connected to roller B; the main gear meshes with its corresponding secondary gear during sliding; and the frame is connected to a tensioning component.

[0005] Based on the above technical solutions, the present invention also provides the following optional technical solutions: A further technical solution: A motor is fixedly connected to the frame, an output gear is fixedly connected to the output shaft of the motor, the output gear meshes with rack A, rack A is fixedly connected to a connecting rod, the connecting rod is fixedly connected to a frame, a limit rod is fixedly connected to the connecting rod, the limit rod is slidably connected to a connector, the connector is fixedly connected to the frame, and the output gear is connected to the embossing assembly.

[0006] Further technical solution: The embossing assembly includes a driven gear, a shaft, a bevel gear, and a bevel gear B. After the frame slides to the end, the driven gear meshes with the output gear to drive the rolls A and B to tighten the leather after they clamp the leather. The shaft is fixedly connected to the driven gear and rotatably connected to the frame. The bevel gear is fixedly connected to the shaft and meshes with the bevel gear B.

[0007] A further technical solution: A lead screw is fixedly connected to the shaft of the bevel gear B. The lead screw is rotatably connected to the frame. A sliding sleeve is threaded onto the lead screw. The sliding sleeve is slidably connected to the slide rod. The slide rod is fixedly connected to the frame. A pressure plate is fixedly connected to the sliding sleeve.

[0008] A further technical solution: The other end of the pressure plate is fixedly connected to the connecting block, the connecting block is slidably connected to the frame, and racks are symmetrically fixedly connected to both sides of the connecting block. The racks are meshed with the main gear so as to drive the roller B and roller A to rotate synchronously during their sliding process, thereby tightening the leather.

[0009] Further technical solution: The traction assembly includes a screw, a slide, a shaft, and a short shaft. The screw is rotatably connected to the frame. The slide is threaded onto the screw. The slide is slidably connected to the shaft. The shaft is fixedly connected to the frame. The short shaft is rotatably connected to the slide. A damping rubber ring is provided at the connection between the slide and the short shaft.

[0010] A further technical solution: A gear is fixedly connected to the short shaft, and a cam is fixedly connected to the end of the short shaft. The cams on the same side are symmetrically arranged. The gear meshes with rack B. Rack B is fixedly connected to the frame. One end of the screw is fixedly connected to the output shaft of motor A. Motor A is fixedly connected to the frame.

[0011] Beneficial effects This invention provides an anti-counterfeiting label embossing device, which has the following advantages compared with the prior art: 1. The user places the leather to be printed on the frame, placing it on the two rolls A. The user then starts the motor, causing the output gear fixedly connected to its output shaft to rotate. At this time, rack A begins to move linearly under the engagement of the output gear, causing the connecting rod to drive the frame fixedly connected to it to slide synchronously. The frame then slides downwards along its connection with the guide rod, causing the roll B, which is rotatably connected to it, to contact the leather placed on roll A. Simultaneously, when rack A stops engaging with the output gear, the frame stops sliding and roll B presses against the leather on roll A. Thus, the leather is clamped by the cooperation of rolls A and B. At the same time, the damping strip on the guide rod effectively increases the damping of the sliding of the connecting lug, thereby preventing the frame from sliding upwards and causing rolls B and roll A to be unable to effectively clamp the leather. At the same time, the main gear is driven by the frame to move and engage with the secondary gear, so as to drive rolls B and roll A to cooperate to tighten the leather. 2. When the frame stops sliding, drum A is moved by the frame to engage with the output gear. At this time, the motor remains running, causing the output gear to drive the driven gear connected to it to rotate synchronously. The shaft fixedly connected to the driven gear's axis rotates at a constant speed, causing the bevel gear fixedly connected to the shaft to rotate synchronously. Meanwhile, bevel gear B, in cooperation with the bevel gear it engages with, begins to drive the lead screw fixedly connected to its axis to rotate synchronously. This causes the sliding sleeve threaded onto the lead screw to begin linear movement downwards along its connection with the slide rod. This causes the pressure plate fixedly connected to the sliding sleeve to slide towards the leather and gradually contact the leather for pressing and positioning. During this process, one end of the pressure plate is fixedly connected to... The connecting blocks slide synchronously, causing the racks fixedly connected to both sides of the connecting blocks to slide synchronously. At this time, the main gear begins to rotate at a constant speed in cooperation with the racks meshing with it, and the auxiliary gear meshing with the bottom of the main gear rotates synchronously. Since the main gear is larger than the auxiliary gear, the rack can avoid contact with the auxiliary gear during its sliding process, thus avoiding interference with the rotation of the auxiliary gear. At this time, the main gear and the auxiliary gear begin to rotate in opposite directions, driving the rollers B and A fixedly connected with them to rotate synchronously, thus beginning to push the leather material clamped between rollers A and B to both sides. When the pressure plate contacts the leather material, the leather material is in a taut state, preventing the surface of the leather material from being too loose during the imprinting process, which would cause the markings to be deformed and unclear. 3. When rolls A and B push the leather to both sides, one end of the leather is pushed between the two cams. Then, the user starts motor A, which causes the screw fixedly connected to the shaft of motor A to start rotating at a constant speed. The sliding plate connected to the screw threaded on the screw starts to move linearly along the connection between the screw and the shaft. At the same time, the sliding plate drives the gear to slide synchronously, and the gear starts to roll on the rack B that meshes with it. At this time, the short shaft fixedly connected to the shaft of the gear rotates synchronously. Then, the short shaft starts to drive the cam fixedly connected to it to rotate synchronously, so that the two cams gradually come into contact with the leather. When their central axes are aligned, the two cams cooperate to clamp the leather between them. At this time, the user keeps motor A in the running state, so that the sliding plate continues to slide and begins to pull the leather, so that after the leather is imprinted, it can be pulled out of the imprinting area to avoid affecting the subsequent leather imprinting.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1-6 According to one embodiment of the present invention, an anti-counterfeiting label embossing device includes a frame 101 and further includes: Positioning component 2 is used to tighten the leather; Please see Figure 1 as well as Figure 2 The positioning component 2 includes a drum A201, a secondary gear 202, a guide rod 203, a connecting ear 204, a frame 205, a drum B206, and a main gear 207. Two drums A201 are symmetrically rotatably connected to the bottom of the frame 101. The secondary gear 202 is fixedly connected to the drum A201. Two guide rods 203 are symmetrically fixedly connected to the frame 101. The connecting ear 204 is slidably connected to the guide rod 203. The frame 205 is fixedly connected to the connecting ear 204. Two drums B206 are symmetrically rotatably connected to the frame 205. The main gear 207 is fixedly connected to the drum B206. During sliding, the main gear 207 meshes with its corresponding secondary gear 202. The frame 101 is connected to the traction component 4.

[0022] Please see Figure 1 as well as Figure 2 Specifically, a motor 208 is fixedly connected to the frame 101, and an output gear 209 is fixedly connected to the output shaft of the motor 208. The output gear 209 meshes with a rack A2001, which is fixedly connected to a connecting rod 2002. The connecting rod 2002 is fixedly connected to a frame 205, and a limiting rod 2003 is fixedly connected to the connecting rod 2002. The limiting rod 2003 is slidably connected to a connector 2004, which is fixedly connected to the frame 101. The output gear 209 is connected to the imprinting assembly 3.

[0023] In this embodiment of the invention, the user places the leather material to be imprinted on the frame 101, positioning it above the two rollers A201. The user then starts the motor 208, causing the output gear 209 fixedly connected to its output shaft to rotate. At this time, the rack A2001 begins to move linearly in cooperation with the output gear 209, causing the connecting rod 2002 to synchronously slide along the frame 205 fixedly connected to it. The frame 205 then slides downwards along its connection with the guide rod 203, causing the roller B206, which is rotatably connected to it, to contact the leather material placed on the roller A201. Simultaneously... When rack A2001 stops meshing with output gear 209, frame 205 stops sliding and drum B206 presses against the leather on drum A201. Thus, the leather is clamped by the cooperation of drum A201 and drum B206. At the same time, the damping strip on guide rod 203 can effectively increase the damping of connecting ear 204, thereby preventing frame 205 from sliding upward, which would prevent drum B206 and drum A201 from effectively clamping the leather. Meanwhile, main gear 207 is driven by frame 205 to move and mesh with secondary gear 202, so as to drive drum B206 and drum A201 to cooperate to tighten the leather.

[0024] Please see Figure 1 as well as Figure 3 Specifically, the embossing assembly 3 includes a driven gear 301, a shaft 302, a bevel gear 303, and a bevel gear B304. The driven gear 301 engages with the output gear 209 after the frame 205 slides to its end, so that after the roll A201 and roll B206 clamp the leather, the output gear 209 drives the roll A201 and roll B206 to tighten the leather. The shaft 302 is fixedly connected to the driven gear 301 and rotatably connected to the frame 205. The bevel gear 303 is fixedly connected to the shaft 302 and engages with the bevel gear B304.

[0025] Please see Figure 3Specifically, a lead screw 305 is fixedly connected to the shaft of the bevel gear B304. The lead screw 305 is rotatably connected to the frame 205. A sliding sleeve 306 is threaded onto the lead screw 305. The sliding sleeve 306 is slidably connected to the sliding rod 307. The sliding rod 307 is fixedly connected to the frame 205. A pressure plate 308 is fixedly connected to the sliding sleeve 306.

[0026] Please see Figure 1 , Figure 3 as well as Figure 5 Specifically, the other end of the pressure plate 308 is fixedly connected to the connecting block 309, the connecting block 309 is slidably connected to the frame 205, and racks 3001 are symmetrically fixedly connected to both sides of the connecting block 309. The racks 3001 are meshed with the main gear 207 so as to drive the rollers B206 and A201 to rotate synchronously during their sliding process, thereby tightening the leather.

[0027] In this embodiment of the invention, when the frame 205 stops sliding, the drum A201 is driven by the frame 205 to move horizontally and engage with the output gear 209. At this time, the motor 208 remains running, causing the output gear 209 to drive the driven gear 301, which is engaged with it, to rotate synchronously. The shaft 302, fixedly connected to the center of the driven gear 301, rotates at a constant speed, causing the bevel gear 303, fixedly connected to the shaft 302, to rotate synchronously. The bevel gear B304, in cooperation with the bevel gear 303, begins to drive the lead screw 305, fixedly connected to its center, to rotate synchronously. This causes the sliding sleeve 306, threaded onto the lead screw 305, to begin linear movement downwards along its connection with the sliding rod 307. This causes the pressure plate 308, fixedly connected to the sliding sleeve 306, to begin sliding towards the leather and gradually contacting it for pressing and positioning. During this process, one end of the pressure plate 308 is fixed... The connecting block 309 slides synchronously, causing the racks 3001 fixedly connected to both sides of the connecting block 309 to slide synchronously. At this time, the main gear 207 begins to rotate at a constant speed under the cooperation of the racks 3001 meshing with it, and the auxiliary gear 202 meshing with the bottom of the main gear 207 rotates synchronously. Since the size of the main gear 207 is larger than that of the auxiliary gear 202, the rack 3001 can avoid contact with the auxiliary gear 202 during its sliding process, thus avoiding interference with the rotation of the auxiliary gear 202. At this time, the main gear 207 and the auxiliary gear 202 begin to rotate in opposite directions, driving the rollers B206 and A201 fixedly connected with them to rotate synchronously, thus beginning to push the leather material clamped between rollers A201 and B206 to both sides, so that when the pressure plate 308 contacts the leather material, the leather material is in a taut state, avoiding the surface of the leather material being too loose during the imprinting, which would cause the marking to be deformed and unclear.

[0028] Please see Figure 4 as well as Figure 6Specifically, the traction assembly 4 includes a screw 401, a slide 402, a shaft 403, and a short shaft 404. The screw 401 is rotatably connected to the frame 101. The slide 402 is threaded onto the screw 401. The slide 402 is slidably connected to the shaft 403. The shaft 403 is fixedly connected to the frame 101. The short shaft 404 is rotatably connected to the slide 402. A damping rubber ring is provided at the connection between the slide 402 and the short shaft 404.

[0029] Please see Figure 4 as well as Figure 6 Specifically, a gear 405 is fixedly connected to the short shaft 404, and a cam 406 is fixedly connected to the end of the short shaft 404. The cams 406 on the same side are symmetrically arranged. The gear 405 is meshed with a rack B407, and the rack B407 is fixedly connected to the frame 101. One end of the screw 401 is fixedly connected to the output shaft of the motor A408, and the motor A408 is fixedly connected to the frame 101.

[0030] In this embodiment of the invention, when the roll A201 and roll B206 push the leather material to both sides, one end of the leather material can be pushed between the two cams 406. Then, the user starts the motor A408, which causes the screw 401 fixedly connected to the shaft of the motor A408 to start rotating at a constant speed, and causes the sliding plate 402 threaded on the screw 401 to start moving linearly along its connection with the shaft 403. At the same time, during the sliding of the sliding plate 402, the gear 405 can be driven to slide synchronously, and the gear 405 engages with the rack B407 connected to it. The material begins to roll on it. At this time, the short shaft 404, which is fixedly connected to the shaft of gear 405, rotates synchronously. Then, the short shaft 404 starts to drive the cam 406, which is fixedly connected to it, to rotate synchronously. This causes the two cams 406 to gradually come into contact with the leather. When their central axes are aligned, the two cams 406 cooperate to clamp the leather between them. At this time, the user keeps the motor A408 in the running state, so that the slide 402 continues to slide and begins to pull the leather. This is so that after the leather is imprinted, it can be pulled out of the imprinting area to avoid affecting subsequent leather imprinting.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: Components are fixed together using screws, splines, wedges, etc. This type of connection allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct. (Such as the length of bolts, keys, and wedges), and tighten them properly.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted]: Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
