Description

Technical Field

[0001] The invention relates to the technical field of laminating machines, in particular to a laminating machine for processing rubber pads. Background Art

[0002] Rubber pads are resistant to oil, acid and alkali, cold and heat, and aging. They can be directly cut into sealing gaskets of various shapes and are widely used in various fields. In order to further enhance the durability of rubber pads, improve the wear resistance of rubber pads, and make them waterproof, dustproof, and easy to clean and maintain, rubber pads are usually laminated. During the laminating process of rubber pads, laminating machines are usually used for laminating.

[0003] Laminating machine is a special equipment for paper, board and film mounting. It is pressurized by rubber roller and heating roller together to form a paper-plastic product.

[0004] Specifically, laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. The coating laminating machine includes three parts: gluing, drying, and hot pressing. It has a wide range of applications and stable and reliable processing performance. It is a widely used laminating equipment in China. The pre-coating laminating machine, without gluing and drying parts, is not only suitable for laminating large quantities of printed products, but also for laminating small quantities and scattered printed products such as automated desktop office systems.

[0005] The laminating machine in the prior art, such as the Chinese patent with the authorization announcement number CN217346711U and the name of a regenerated rubber laminating device, discloses a regenerated rubber laminating device in the above patent, which relates to the technical field of regenerated rubber production devices, including a laminating processing box, a controller body is fixedly installed on the top of the laminating processing box, a closed door is rotatably connected to the front of the laminating processing box, an automatic laminating mechanism is arranged in the inner cavity of the laminating processing box, and a deodorizing mechanism is arranged on the top of the laminating processing box. In the above patent, by pre-laying the rubber pad on the top of the horizontal working plate, and then connecting the end of the protective film on the outer surface of the material shaft roller body to the left end of the rubber pad, the control screw drive structure body works to drive the material shaft roller body to rotate and move right, so that the protective film is unfolded to the top of the rubber pad, that is, the function of automatic laminating is realized, the production efficiency of rubber is improved, and the efficiency of the device is increased.

[0006] In the prior art, there is a Chinese patent with the authorization announcement number CN214324508U, entitled "A Fully Automatic Laminating Machine". The patent discloses a fully automatic laminating machine, including a base, a control box bolted to the top of the base, a workbench bolted to the top of the control box, a mounting seat bolted to the top of the workbench, a rotating roller arranged between the mounting seats, a conveyor belt sleeved on the surface of the rotating roller, the rotating rollers are connected by a conveyor belt transmission, and a fixing plate is bolted to the front and rear sides of the top of the base. The patent can effectively make the plastic film and paper stick together and avoid bubbles between the plastic film and paper by setting the rotating roller, conveyor belt, smoothing roller, rubber pad and motor, thus solving the problem that the laminating effect of the laminating machine currently used in paper production is poor, so that the plastic film and paper cannot be effectively stuck together and bubbles are easily formed between the plastic film and paper.

[0007] Laminating machines such as those in the above-mentioned patents can achieve laminating operations to a certain extent. According to the above-mentioned patents, after the rubber pad completes the laminating operation, it is necessary to press the rubber pad after lamination. By squeezing the rubber pad, not only can the interface bubbles be eliminated, but also the interface bonding strength between the film and the rubber pad can be significantly improved. And after the rubber pad completes the laminating operation, it needs to be transferred to another die-cutting device for die-cutting operations. At this time, it is necessary to transfer the process between two independent sets of equipment. During the transmission process, it will not only affect the work efficiency, but also when the rubber pad after lamination runs under the die-cutting equipment, it needs to be repositioned and calibrated, and the multiple devices are controlled by independent systems, which will further increase the production cost. It can be seen that how to complete the film cutting operation on a single device during the extrusion of the rubber pad that has completed the lamination operation is a technical problem that needs to be solved urgently.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: when working, the servo cylinder drives the carrying box to move downward, and the downward movement of the carrying box will first drive the extrusion unit to abut against the rubber pad body, and as the carrying box continues to move downward, it will drive the extrusion unit to continue to abut against the rubber pad body. When the extrusion unit reaches the maximum limit, the carrying box continues to move downward, which will cause the extrusion unit and the carrying box to move in the opposite direction, that is, with the carrying box as a reference, the extrusion unit drives the unlocking part to move upward, and the locking part is driven to slide out of the cutting unit through the unlocking part. At this moment, the cutting unit will slide downward quickly to cut the film on the outside of the rubber pad body. Since the extrusion unit is still in the state of extruding the rubber pad body at this moment, the rubber pad body can be kept in a stationary state when the cutting unit is cutting, and the cutting quality of the film can be further improved.

[0020] After the cutting unit completes a cutting operation on the rubber pad body, the servo cylinder will drive the carrier box upward. During the process of the servo cylinder driving the carrier box to slide upward, the reset mechanism drives the locking member to lock the cutting unit again.

Instead, when the carrier box drives the cutting unit to complete the cutting operation and then moves upward to reset, the fixing of the cutting unit is realized passively, which greatly improves the working efficiency of the laminating machine and further saves costs.

[0021] By moving the carrier box downward and upward, it is possible to squeeze the rubber pad body after laminating and then complete the cutting operation. There is no need to transport the rubber pad body after the laminating operation to a cutting device for cutting, which can improve the working efficiency of the laminating machine and also save costs. And because there is no need to transport the rubber pad body to a cutting device, not only is the procedure saved at this moment, but there is also no need to fix the rubber pad body again, which can improve the cutting quality to a certain extent.

[0022] Furthermore, in the present invention, during the process of the carrier box driving the cutting unit to complete the cutting operation on the film and then moving upward to reset, the intermittent linkage mechanism drives the power rod to rotate, and the conveyor roller drives the conveyor belt to move, so as to convey the rubber pad body after the laminating operation, which greatly improves the working efficiency of the laminating machine. And during this process, there is no need for an additional driving source to drive the conveyor belt to rotate. Instead, when the carrier box drives the cutting unit to complete the cutting operation on the film and then moves upward to reset, the rotation of the conveyor belt is realized passively, and the rubber pad body after the laminating operation can be conveyed to a predetermined position. Therefore, not only can it save energy consumption, but also reduce the coordinated control between procedures, and further save costs while reducing the occurrence of mistakes, with better effects.

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1-17 , the present invention provides a technical solution: a film laminating machine for processing a rubber pad body, which includes a conveying frame 1 and a processing frame 2 installed on the conveying frame 1. Specifically, a plurality of support members are provided on both the processing frame 2 and the bottom of the conveying frame 1, so as to improve the stability of the film laminating machine during operation. The film 4 can be a polyurethane (PU) film 4, a polyvinyl chloride (PVC) film 4, etc., and can be selected according to the working needs. The film 4 is installed on the processing frame 2 through a carrying roller 3, a guide roller assembly and a winding roller 5, and a conveyor belt 10 for conveying the rubber pad body 9 is provided on the conveying frame 1 through a plurality of conveying rollers 17. Preferably, an installation groove 8 adapted to the rubber pad body 9 is provided on the conveyor belt 10, and the rubber pad body 9 is installed on the conveyor belt 10 through the installation groove 8 to improve the stability of the rubber pad body 9 during transportation.

[0044] Among them, a bearing box 6 is vertically slidably connected to the processing frame 2 through a servo cylinder 7, which provides power for the vertical sliding of the bearing box 6. Preferably, limiting rods are fixedly connected to both sides of the bearing box 6, and limiting grooves adapted to the limiting rods are formed on the side wall of the processing frame 2, wherein the limiting rods are slidably connected in the limiting grooves to improve the stability of the vertical sliding of the bearing frame.

[0045] Among them, an extrusion unit 11 is arranged inside the bearing box 6, and the film 4 is arranged between the extrusion unit 11 and the conveyor belt 10. Therefore, when the bearing box 6 receives the downward power generated by the servo cylinder 7, it will drive the extrusion unit 11 to move downward to perform an extrusion operation on the film 4 covered on the rubber pad body 9, reducing the gaps, air bubbles, etc. between the film 4 and the rubber pad body 9. At the same time, after the extrusion unit 11 extrudes between the rubber pad body 9 and the film 4, it can also significantly improve the interfacial bonding strength between the film 4 and the rubber pad body 9, with better effects. And a cutting unit is slidably connected inside the bearing box 6, wherein the shape of the cutting unit is the same as that of the rubber pad body 9, so as to meet the cutting operation of the film 4. A locking member 14 is arranged between the cutting unit and the bearing box 6. Specifically, when the cutting operation is not required, the cutting unit is locked by the locking member. At this moment, the cutting unit is located inside the bearing box 6 and does not contact the film 4. When the locking member 14 moves away from the cutting unit, the cutting unit will quickly slide downward to cut the film 4 outside the rubber pad body 9 to meet the working requirements.

[0046] And an unlocking portion 15 is arranged between the extrusion unit 11 and the locking member 14. The unlocking portion 15 is used to enable the locking member 14 to slide out of the cutting unit, that is, to unlock the cutting unit. At this moment, the cutting unit will quickly slide downward to cut the film 4 outside the rubber pad body 9 to meet the working requirements.

[0047] Specifically, in the present invention, the upward and downward movement of the bearing box 6 driven by the servo cylinder 7 can be specifically divided into two working positions.

[0048] The first working station: When the servo cylinder 7 drives the carrier box 6 to slide downward, during the process of the extrusion unit 11 extruding the film 4 covered on the rubber pad body 9, after the unlocking part 15 unlocks the locking piece 14 for limiting the cutting unit, the cutting unit cuts the film 4 outside the rubber pad body 9 after film covering. During the above working process, the servo cylinder 7 drives the carrier box 6 to move downward. During the downward movement of the carrier box 6, it will first drive the extrusion unit 11 to abut against the rubber pad body 9. As the carrier box 6 continues to move downward, it will drive the extrusion unit 11 to continuously abut against the rubber pad body 9. When the extrusion unit 11 reaches the maximum limit and the carrier box 6 continues to move downward, a reverse movement will occur between the extrusion unit 11 and the carrier box 6, that is, with the carrier box 6 as the reference object, the extrusion unit 11 drives the unlocking part 15 to move upward, and the locking piece 14 is driven by the unlocking part 15 to slide out of the cutting unit where it is located. At this moment, the cutting unit will quickly slide downward to cut the film 4 outside the rubber pad body 9. Since the extrusion unit 11 is still in the state of extruding the rubber pad body 9 at this moment, it can improve the state of the rubber pad body 9 being stationary during the cutting by the cutting unit, and further improve the cutting quality of the film 4.

[0049] Among them, a reset mechanism 16 is also provided between the processing frame 2 and the carrier box 6. The reset mechanism 16 can drive the cutting unit to be passively fixed by the locking piece 14 to facilitate subsequent cutting operations on the film 4 again, and operate in a cycle. In the second working station, after the cutting unit completes a cutting operation on the rubber pad body 9, at this time, the servo cylinder 7 will drive the carrier box 6 to move upward. When the servo cylinder 7 drives the carrier box 6 to slide upward, the reset mechanism 16 drives the locking piece 14 to lock the cutting unit again. At this moment, after the reset mechanism 16 drives the cutting unit to be fixed by the locking piece 14 again, the extrusion unit 11 is also in the original state to facilitate the cutting operation on the next rubber pad body 9. At the same time, during this process, there is no need to actively set a driving source to drive the cutting unit to reset, but the cutting unit is passively fixed by driving the carrier box 6 to drive the cutting unit to complete the cutting operation and then move upward to reset, which greatly improves the working efficiency of the laminating machine and further achieves the effect of cost saving. Then repeat the above actions and run in a cycle.

[0050] Specifically, through the downward and upward movement of the carrier box 6, it is possible to extrude the rubber pad body 9 after film covering and complete the cutting operation, without transporting the rubber pad body 9 after the film covering operation to the cutting equipment for cutting, which can improve the working efficiency of the laminating machine and also achieve the effect of cost saving. And since there is no need to transport the rubber pad body 9 to the cutting equipment, at this moment, not only is the program saved, but there is also no need to fix the rubber pad body 9 again, thus to a certain extent, it can achieve the effect of improving the cutting quality.

[0051] In the embodiment provided by the present invention, a power rod 19 is fixedly connected to one of the conveying rollers 17, wherein the multiple conveying rollers 17 are connected by transmission through the synchronous components in the prior art, that is, when one of the conveying rollers 17 rotates, it will drive multiple groups of conveying rollers 17 to rotate, so as to realize the movement of the conveyor belt 10, and to convey the rubber pad body 9 after the laminating operation is completed. And the reset mechanism 16 is connected to the power rod 19 by transmission through the intermittent linkage mechanism 18, that is, the servo cylinder 7 drives the carrying box 6 to move upward and downward, which will produce two different states for the conveyor belt 10.

[0052] First, when the servo cylinder 7 drives the carrying box 6 to move downward, the intermittent linkage mechanism 18 will not drive the power rod 19 to rotate, and the multiple groups of conveying rollers 17 will not rotate, so the conveyor belt 10 is in a stationary state.

[0053] Second, when the servo cylinder 7 drives the carrying box 6 upwards and drives the locking member 14 to lock the cutting unit again through the reset mechanism 16, the intermittent linkage mechanism 18 drives the power rod 19 to rotate, so that the conveyor belt 10 rotates to convey the rubber pad body 9 after the film lamination is completed and cut. Therefore, in the above operation process, the carrying box 6 drives the cutting unit to complete the film 4 and resets upwards, and the intermittent linkage mechanism 18 drives the power rod 19 to rotate, and the conveyor belt 10 is driven to move through the conveying roller 17, so that the rubber pad body 9 after the film lamination is completed can be conveyed, which greatly improves the working efficiency of the laminating machine. And in this process, no additional driving source is required to drive the conveyor belt 10 to rotate. Instead, the conveyor belt 10 is passively rotated during the upward reset stroke after the cutting unit is driven by the carrying box 6 to complete the cutting operation of the film 4. The rubber pad body 9 after the lamination operation is completed can be transported to a predetermined position. Therefore, it can not only save energy, but also reduce the coordination and control between programs, thereby saving costs and reducing the occurrence of errors, with better results.

[0054] In the embodiments provided by the present invention, specifically, the extrusion unit 11 includes an extrusion block 111, where the extrusion block 111 can be made of materials such as rubber and silica gel. The extrusion block 111 is slidably connected to the carrier box 6 through a connecting rod 112, which can improve the stability when the extrusion block 111 slides relative to the carrier box 6. Moreover, a plurality of positioning springs 113 are arranged between the extrusion block 111 and the carrier box 6, and the elastic force of the positioning springs 113 drives the extrusion block 111 to be located below the carrier box 6. Therefore, in the original state, the elastic force of the positioning springs 113 drives the extrusion block 111 to be located below the carrier box 6. During the working process, when the servo cylinder 7 drives the carrier box 6 to move downward, at this moment, the carrier box 6 drives the extrusion block 111 to move downward together. Then, the extrusion block 111 will first come into contact with the rubber pad body 9. After that, as the carrier box 6 continues to move downward, it will drive the extrusion block 111 to continuously contact the rubber pad body 9. When the extrusion block 111 can no longer move downward, as the carrier box 6 continues to move downward, at this moment, taking the carrier box 6 as a reference, the extrusion block 111 will drive the connecting rod 112 to move upward to facilitate subsequent operations.

[0055] In the embodiment provided by the present invention, the cutting unit includes a cutting knife 12 slidably connected inside the carrying box 6, and the shape of the cutting knife 12 is the same as that of the rubber pad body 9. A plurality of sets of power springs 121 are arranged between the cutting knife 12 and the carrying box 6. Specifically, the elastic force of the power springs 121 drives the cutting knife 12 to move downward, so that the cutting knife 12 completes the cutting operation on the film 4. Preferably, a connecting frame 13 is fixedly connected to the cutting knife 12, which is convenient for controlling the state of the cutting knife 12, that is, when the connecting frame 13 slides, it will drive the cutting knife 12 to slide together. The locking member 14 includes a locking block 141 slidably connected inside the carrying frame. Preferably, the locking block 141 can be wedge-shaped. More specifically, a positioning block 143 is fixedly connected to the locking block 141. In order to improve the stability of the locking block 141 when sliding, a fixing rod 142 is arranged between the locking block 141 and the positioning block 143. At the same time, there are two sets of locking blocks 141 and wedge-shaped locking grooves, which are respectively slidably connected to both sides of the carrying box 6. A locking spring 144 is arranged between the positioning block 143 and the carrying box 6. Preferably, the locking spring 144 is arranged between the two positioning blocks 143. A wedge-shaped locking groove adapted to the locking block 141 is formed on the connecting frame 13. The elastic force of the locking spring 144 drives the locking block 141 to be clamped in the wedge-shaped locking groove, and at this moment the cutting knife 12 is in a static state. In the embodiment provided by the present invention, the unlocking part 15 includes an unlocking block 151 fixedly connected to the connecting rod 112. An unlocking groove 152 adapted to the unlocking block 151 is formed on the positioning block 143. The unlocking block 151 and the unlocking groove 152 are intermittently abutted. When the unlocking block 151 abuts against the unlocking groove 152 and the unlocking block 151 continues to move upward, at this moment the unlocking block 151 will drive the two positioning blocks 143 to approach each other, so that the locking block 141 slides out of the wedge-shaped locking groove where it is located. At this moment, the elastic force of the power spring 121 after the unlocking restriction drives the cutting knife 12 to move downward, so that the cutting knife 12 completes the cutting operation on the film 4.

[0056] Specifically, during the above-mentioned usage process, when the servo cylinder 7 drives the bearing box 6 to move downward, at this moment, the bearing box 6 drives the extrusion block 111 to move downward together. Then, the extrusion block 111 will first come into contact with the rubber pad body 9. After that, as the bearing box 6 continues to move downward, it will drive the extrusion block 111 to continuously contact the rubber pad body 9. When the extrusion block 111 can no longer move downward, as the bearing box 6 continues to move downward, at this moment, taking the bearing box 6 as a reference, the extrusion block 111 will drive the connecting rod 112 to move upward. At this moment, the connecting rod 112 will drive the unlocking block 151 to be inserted into the unlocking groove 152 inside the positioning block 143. As the bearing box 6 continues to move downward, at this moment, the cooperation between the unlocking block 151 and the unlocking groove 152 will drive the locking block 141 to slide out of the wedge-shaped locking groove where it is located. At this moment, the power spring 121 will drive the cutting knife 12 to move downward under the elastic force after unlocking the restriction, so that the cutting knife 12 can complete the cutting operation on the film 4. The operation process is simple and convenient, meeting the working needs.

[0057] In the embodiments provided by the present invention, specifically, the reset mechanism 16 includes a wedge-shaped force-receiving block 161 fixedly connected to the connecting frame 13, and a wedge-shaped push block 162 is slidably connected to the processing frame 2. When the wedge-shaped push block 162 abuts against the wedge-shaped force-receiving block 161 and the wedge-shaped push block 162 is continuously driven to slide, the wedge-shaped push block 162 at this moment will drive the wedge-shaped force-receiving block 161 to move further upward. Furthermore, the cutting knife 12 can be driven by the connecting frame 13 to move upward to a predetermined position, and then the state of the cutting knife 12 is fixed by the locking member 14. Preferably, a reset member is provided between the wedge-shaped push block 162 and the processing frame 2. Specifically, the reset member includes a slide rod 163 fixedly connected to the wedge-shaped push block 162, and a driving frame 164 is fixedly connected to the slide rod 163. The driving frame 164 is fixedly connected to the wedge-shaped push rod through the slide rod 163. The slide rod 163 is slidably connected to the processing frame 2, and a reset spring 169 is provided between the slide rod 163 and the processing frame 2. The elastic force of the reset spring 169 drives the wedge-shaped push rod away from the wedge-shaped force-receiving block 161. A power member for driving the wedge-shaped push block 162 to slide intermittently is provided between the bearing box 6 and the processing frame 2. The power member includes a first rack 165 fixedly connected to the wedge-shaped push block 162. Specifically, the first rack 165 is fixedly connected to the driving frame 164. When the first rack 165 slides, it will drive the driving frame 164 to slide together. A rotating rod is rotatably connected to the processing frame 2. An intermittent gear 166 meshing with the first rack 165 intermittently is installed on the rotating rod, and a driving gear 168 is further provided on the rotating rod. A second rack 167 is fixedly connected to the bearing box 6, and the second rack 167 meshes with the driving gear 168. Specifically, during the upward reset stroke of the bearing box 6 driven by the servo cylinder 7, when the second rack 167 is in the meshing state with the driving gear 168, the driving gear 168 rotates to drive the rotating rod to rotate, so that the intermittent gear 166 is driven to rotate during the rotation stroke of the rotating rod. When the intermittent gear 166 meshes with the first rack 165, the intermittent gear 166 rotates to slide the first rack 165. When the first rack 165 slides, it will drive the driving frame 164 to slide together. Furthermore, the slide rod 163 can be driven to slide through the driving frame 164, so that the wedge-shaped push rod slides on the processing frame 2. At this moment, when the wedge-shaped push block 162 abuts against the wedge-shaped force-receiving block 161 and the bearing box 6 moves upward, the wedge-shaped push block 162 can drive the wedge-shaped force-receiving block 161 to move further upward. At this moment, a certain displacement will be generated between the wedge-shaped force-receiving block 161 and the bearing box 6, that is, the sliding frame will move upward inside the bearing box 6. Before the above movement, since the bearing box 6 moves upward by a certain amount, the extrusion spring 1842 will drive the extrusion block 111 to move downward. At this moment, the unlocking portion 15 will move away from the locking block 141. At this moment, under the elastic action of the locking spring 144, the locking block 141 is driven to reach a predetermined position.Therefore, when the carriage generates a displacement relative to the carrier box 6, the carriage will drive the locking block 141 to press against the locking spring 144. Until the carriage moves upward to the position of the locking groove, the elastic force of the locking spring 144 drives the locking block 141 to be clamped inside the locking groove, fixing the state of the carriage, and further fixing the state of the cutting knife 12. At the same time, during this process, when the intermittent gear 166 drives the wedge-shaped push block 162 to slide to the maximum extent, it can just make the locking block 141 be clamped in the wedge-shaped locking groove again, and a "click" sound is heard. At this moment, as the intermittent gear 166 continues to rotate, the intermittent gear 166 disengages from the first rack 165, and the elastic force of the return spring 169 drives the wedge-shaped push block 162 to return together to facilitate subsequent reuse. The above operation process can be repeated to realize the cutting operation of the cutting knife 12 and reset after the cutting operation is completed, meeting the working requirements.

[0058] In the embodiment provided by the present invention, specifically, the intermittent linkage mechanism 18 includes a linkage rod 181 and a transmission rod 185 rotatably connected to the processing frame 2, and the linkage rod 181 and the transmission rod 185 are transmission-connected through an intermittent linkage unit 184, and the intermittent linkage unit 184 includes a mounting rod 1841 slidably connected in the linkage rod 181. Specifically, a positioning portion is provided between the mounting rod 1841 and the linkage rod 181, so that the mounting rod 1841 can only be slidably connected to the linkage rod 181, and when the linkage rod 181 rotates, it will drive the mounting rod 1841 to rotate together. A compression spring 1842 is provided between the mounting rod 1841 and the linkage rod 181. The mounting rod 1841 is fixedly connected with a first cylinder 1843, and the first cylinder 1843 is provided with tooth grooves 1844 in a circumferential array. The transmission rod 185 is fixedly connected with a second cylinder 1845, and the second cylinder 1845 is fixedly connected with wedge-shaped teeth 1846 adapted to the tooth grooves 1844. The elastic force of the extrusion spring 1842 drives each wedge-shaped tooth 1846 to be respectively engaged in the corresponding tooth groove 1844, and the tooth groove 1844 is adapted to the wedge-shaped teeth 1846. A gear set 20 is provided between the transmission rod 185 and the power rod 19. Specifically, the gear set 20 includes a first bevel gear installed on the transmission rod 185 and a second bevel gear installed on the power rod 19, and the first bevel gear is meshed with the second bevel gear. The linkage rod 181 is fixedly connected with a transmission gear 183, and the bottom of the second rack 167 is fixedly connected with a long rack 182 through a connecting plate, and the long rack 182 meshes with the transmission gear 183. Specifically, in the present invention, when the carrying box 6 slides downward, the second rack 167 drives the long rack 182 to slide downward together, and at this moment, the linkage rod 181 is driven to rotate by the cooperation between the long rack 182 and the transmission gear 183. When the linkage rod 181 rotates, it drives the installation rod 1841 to rotate together, and then drives the first cylinder 1843 to rotate. At this moment, the wedge-shaped surface of the tooth groove 1844 on the first cylinder 1843 contacts the wedge-shaped surface of the wedge-shaped tooth 1846, so the second cylinder 1845 cannot be driven to rotate together through the wedge-shaped tooth 1846, and then the power rod 19 cannot be driven to rotate through the transmission rod 185.Conversely, when the carrier box 6 moves upward, the long rack 182 is driven to move upward together by the second rack 167. At this moment, the long rack 182 drives the linkage rod 181 to rotate through the cooperation between the long rack 182 and the transmission gear 183. When the linkage rod 181 rotates, it will drive the mounting rod 1841 to rotate together, and then be able to drive the first cylinder 1843 to rotate. At this time, the straight edge of the tooth groove 1844 abuts against the straight edge of the wedge tooth 1846. At this moment, the second cylinder 1845 is driven to rotate by the wedge tooth 1846, so that the transmission rod 185 rotates, and then the power rod 19 can be driven to rotate through the gear set 20. When the power rod 19 rotates, when one of the conveying rollers 17 is driven to rotate by the power rod 19, multiple groups of conveying rollers 17 will be driven to rotate through the synchronous component, so as to realize the movement of the conveyor belt 10. At this moment, the rubber pad body 9 after the film covering operation is conveyed, so that the conveyor belt 10 rotates to convey and discharge the rubber pad body 9 after the film covering and cutting. At this moment, there is no need for an additional drive source to drive the conveyor belt 10 to rotate, but the upward reset stroke of the carrier box 6 after driving the cutting unit to complete the cutting operation of the film 4 is used to passively realize the rotation of the conveyor belt 10, which can convey the rubber pad body 9 after the film covering operation to a predetermined position. Therefore, it can not only save energy consumption, but also reduce the coordinated control between programs, thus saving costs and reducing mistakes at the same time, and the effect is better.

[0059] Preferably, the long rack 182 can be specifically divided into a toothed part and a part without teeth. When the carrier box 6 moves downward, first, the toothed part meshes with the transmission gear 183 to drive the transmission gear 183 to rotate. When the long rack 182 slides downward for a certain stroke, at this moment, the long rack 182 disengages from the transmission gear 183 through the part without teeth and continues to move downward for a certain stroke. When the carrier box 6 needs to be reset upward, first, the part without teeth on the long rack 182 moves upward for a certain stroke, and then the toothed part meshes with the transmission gear 183. During the stroke when the long rack 182 disengages from the transmission gear 183 through the part without teeth, at this time, the carrier box 6 has also moved upward for the same stroke, that is, the pressing block 111 releases the restriction on the rubber pad body 9 to a certain extent and reduces the friction force. When the toothed part meshes with the transmission gear 183, it will drive the intermittent linkage mechanism 18 to drive the conveyor belt 10 to move, realizing the conveyance of the rubber pad body 9. During this process, it can be avoided that the rubber pad body 9 cannot be transmitted due to the large friction force between the pressing block 111 and the rubber pad body 9, further meeting the working requirements.

[0060] In the embodiments provided by the present invention, a synchronization unit 21 is arranged between the winding roller 5 and the transmission rod 185. Specifically, the synchronization unit 21 can be a belt pulley transmission member or a synchronous pulley transmission member, etc., which can realize the winding operation of the waste film 4 after cutting during the conveying process of the conveyor belt 10, facilitating the recycling of the waste film 4.

[0061] In the embodiments provided by the present invention, the guide roller assembly includes a guide roller and a pressing roller rotatably connected to the processing frame 2. The film 4 passes between the guide roller and the pressing roller, which can press the film 4 to realize the pre-pressing of the film 4 after the rubber pad body 9 is coated with the film, further meeting the working requirements. Specifically, there can be multiple groups of guide rollers and pressing rollers, which are prior art and will not be elaborated here.

[0062] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power supply.

[0063] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.
