Description

Technical Field

[0001] This application relates to the technical field of laminators, and more specifically, to a rubber roller pressing adjustment mechanism and a laminator containing the same. Background Technology

[0002] A laminating machine is a device used for laminating documents. It uses symmetrically arranged upper and lower rubber rollers to squeeze the document to be laminated and the laminating film to achieve lamination. The pressure between the upper and lower rubber rollers plays a crucial role in the quality of lamination. When laminating different products, the pressure between the upper and lower rubber rollers needs to be adjusted to adapt to different lamination requirements.

[0003] To adjust the pressure of the upper and lower pressure rollers, existing technologies include adjustment structures in laminators, such as patent document application number 202123044543.8, which discloses a laminator with a pressure adjusting screw assembly. The structure includes a laminator body, a rubber roller mechanism on the laminator body, an upper rubber roller and a lower rubber roller, and a pressure adjusting structure on the rubber roller mechanism. The pressure adjusting structure includes a connecting hook for connecting to the rubber roller mechanism and a pressure adjusting screw assembly for adjusting pressure. One end of the connecting hook is connected to the upper rubber roller, and one end of the pressure adjusting screw assembly passes through the connecting hook and is threadedly connected to the laminator body away from the rubber roller mechanism. The device includes an adjusting screw and a pressure spring. The adjusting screw has a screw-in nut portion and a connecting screw portion. The connecting screw portion passes through the end of the connecting hook away from the glue roller mechanism and is threadedly connected to the body of the sealing machine. An adjustment groove is formed on the end face of the connecting screw portion away from the screw-in nut portion. Although this structure can adjust the pressure between the upper and lower glue rollers, its adjustment position is located on the base of the sealing machine. When adjustment is needed, the entire sealing machine must be flipped over to expose the adjustment groove located at the bottom, which is inconvenient to operate. In addition, its clamping force relies solely on the elastic pushing action of the pressure spring on the clamping part of the connecting hook. Therefore, this force has a certain elastic deformation range and cannot maintain the stability after pressure adjustment. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, this application provides a rubber roller pressing adjustment mechanism that does not require flipping the machine body, and allows for adjustment of the pressure between the upper and lower rubber rollers directly by operating the control panel on the upper outer side of the machine body. The adjustment is convenient and the pressure adjustment is stable.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a rubber roller pressing and adjusting mechanism, which includes a rubber roller mechanism and a pressing and adjusting mechanism disposed in the machine body. The rubber roller mechanism includes an upper rubber roller and a lower rubber roller. The pressing and adjusting mechanism includes an adjusting plate, a fixing plate, and an elastic element. The adjusting plate includes a horizontally arranged pressure plate and a vertically arranged operating plate connected to the pressure plate. The pressure plate is used to press the upper rubber roller from the top. The lower end of the operating plate is provided with adjusting teeth, and the upper part of the operating plate extends out of the outer side of the machine body. The fixing plate is fixed to the bottom plate of the machine body. The fixing plate is provided with a rack. The adjusting teeth are used to engage in the groove between two adjacent teeth on the rack. The elastic element is connected between the adjusting plate and the bottom plate.

[0006] By adopting the above structure, this application adjusts the pressure of the pressure plate on the upper glue roller by adjusting the position of the adjusting teeth on the rack, thereby adjusting the pressure between the upper and lower glue rollers. This adjustment method can ensure the accuracy of pressure adjustment. In addition, this application also sets an elastic element between the operating plate and the base plate. This elastic element can pull the operating plate to make the connection between it and the rack more secure, and it is not easy for the operating plate to detach from the fixed plate. Furthermore, this application extends the upper part of the operating plate out of the outer side of the machine body. When adjustment is needed, it can be adjusted directly by acting on this extended part without flipping the sealing machine, so the operation is more convenient and faster.

[0007] Furthermore, a support plate for supporting the upper and lower rubber rollers is fixed on the base plate, and the two ends of the upper and lower rubber rollers are mounted on the support plate through bearings. With this structure, the adjusting plate can slide along the side wall of the support plate during the process of pulling or pushing by the force application part, and it is not easy to deviate, so that precise meshing can be achieved between it and the rack on the fixed plate.

[0008] Furthermore, the pressure plate is provided with a slot facing downwards, which is used to hook onto the bearings at both ends of the upper glue roller; by using this slot, a stable pressing of the film-coating roller can be achieved, and misalignment is not easily caused.

[0009] Furthermore, the bearing is provided with a radial annular groove, and the retaining groove engages with the radial annular groove. This structure allows the adjusting plate to be limited within the radial annular groove, preventing axial displacement and ensuring the stability of the pressing position and the locking force.

[0010] Furthermore, the fixing plate is provided with inclined extending reinforcing ribs, which are arranged opposite to the rack; this structure can improve the stability of the fixing plate's position during the pushing and pulling process of the adjusting plate, making it less prone to shaking or displacement, thereby improving the accuracy of the meshing position.

[0011] Furthermore, a first hook is provided at the bottom of the operating plate, and a second hook is provided on the corresponding base plate. The elastic element has hooks at both ends, so that the two ends of the elastic element are respectively hooked to the first hook and the second hook. With this structure, the elastic element can be firmly connected between the base plate and the adjusting plate, which can provide sufficient elastic pulling force during the pushing and pulling process of the adjusting plate and achieve stable engagement with the rack on the fixed plate.

[0012] Furthermore, a set of pressure adjustment mechanisms is symmetrically arranged at both ends of the upper glue roller in the axial direction. With this structure, both ends of the upper glue roller can be adjusted to maintain the balance of pressure adjustment between the entire upper glue roller and the lower glue roller, thus ensuring the sealing quality.

[0013] This application also provides a laminator that includes the roller pressing adjustment mechanism described above. With this laminator, the pressure adjustment between the upper and lower rollers can be achieved by pushing and pulling the force application part directly from above the machine body, without needing to flip the laminator, making operation convenient. Furthermore, since this application achieves pressure adjustment and stabilization through rack and pinion engagement, the pressure is more stable compared to the simple spring-assisted push of existing technologies.

[0025] As attached Figure 1-8The diagram illustrates a rubber roller pressing and adjusting mechanism according to this application. This mechanism includes a rubber roller mechanism and a pressing and adjusting mechanism disposed within a machine body 1. The rubber roller mechanism includes an upper rubber roller 2 and a lower rubber roller 3. The pressing and adjusting mechanism includes an operating plate, a fixing plate 5, and an elastic element 6. The operating plate includes a horizontally arranged pressure plate 401 and a vertically arranged operating plate 402 connected to the pressure plate 401. The pressure plate 401 is used to press the upper rubber roller 2 from above. The lower end of the operating plate 402 is provided with adjusting teeth 403, and the upper part of the operating plate 402 extends outward from the outer side of the machine body 1. The fixing plate 5 is fixed to the base plate 7 of the machine body 1. The fixing plate 5 is provided with a rack 501, and the adjusting teeth 403 are used to engage in the grooves between two adjacent teeth on the rack 501. The elastic element 6 connects the operating plate and the base plate 7. Specifically, the body 1 of the sealing machine of this application includes an outer shell and a base 7 connected thereto. At least one set of upper and lower adhesive rollers 2 and 3 are provided, and they are arranged parallel to each other vertically. The elastic element 6 is connected between the adjusting plate 4 and the base plate 7, so that the adjusting plate 4 has a downward pressing force on the upper adhesive roller 2, making the upper adhesive roller 2 tightly adhere to the lower adhesive roller 3. The rack 501 on the fixed plate 5 is fixed to the base plate 7 and remains stationary. The adjusting teeth 403 on the operating plate 402 are used to engage in the grooves between two adjacent teeth on the rack 501 on the fixed plate 5. The operating plate 402 has elastic deformation capability. By pushing and pulling the portion of the operating plate 402 extending outside the base 1, the adjusting teeth 403 cooperate with the operating plate 402, bypassing the teeth on the rack 502 and entering... In adjacent grooves, the adjusting tooth 403 moves up and down relative to the rack 501. When the adjusting tooth 403 moves upward, the pressure plate 401 relaxes its pressure on the upper glue roller 2 through the elastic element 6. When the adjusting tooth 403 moves downward, the pressure plate 401 strengthens its pressure on the upper glue roller 2 through the elastic element 6, thereby adjusting the pressure between the upper glue roller 2 and the lower glue roller 3. Limiting blocks are provided at both the upper and lower ends of the rack 501 on the fixed plate 5. The limiting blocks are used to prevent the adjusting tooth 403 from jumping off the rack 501 and to limit the maximum and minimum pressure of the pressure plate 401 on the upper glue roller. The upper part of the operating plate 402 of this application is always located on the upper outer side of the machine body 1. Therefore, when adjusting the pressure, it is not necessary to flip the sealing machine. The pressure can be adjusted directly through this external part.

[0026] Using the above structure, this application adjusts the pressure of the pressure plate 401 on the upper glue roller 2 by adjusting the position of the adjusting tooth 403 on the rack 501, thereby adjusting the pressure between the upper glue roller 2 and the lower glue roller 3. This adjustment method can ensure the accuracy of pressure adjustment. In addition, this application also provides an elastic element 6 between the operating plate 402 and the base plate 7. The elastic element 6 can pull the operating plate 402 to make the connection between it and the rack more stable, and it is not easy for the operating plate 402 to detach from the fixed plate 5. Furthermore, this application extends the upper part of the operating plate 402 out of the outer side of the machine body 1. When adjustment is required, it can be adjusted directly by acting on the extended part without flipping the sealing machine, so the operation is more convenient and faster.

[0027] As attached Figure 1-4 and Figure 8 As shown, a support plate 8 for supporting the upper rubber roller 2 and the lower rubber roller 3 is fixed on the base plate 7 of this application. The two ends of the upper rubber roller 2 and the lower rubber roller 3 are mounted on the support plate 8 through bearings 9. The support plate 8 can effectively limit and support the position of the upper rubber roller 2 and the lower rubber roller 3 relative to each other. More specifically, the support plate 8 is provided with inclined reinforcing plates on the left and right sides, and a mounting plate connected to the reinforcing plates is provided on the bottom surface. The support plate 8 is fixedly connected to the base plate 7 through mounting holes on the mounting plate. An L-shaped bent plate is also provided on the side. The bent plate and the inclined reinforcing plate form a side wall for the operating plate 402 to slide against. This allows at least three adjacent side walls of the part of the operating plate 402 with the adjusting teeth 403 to abut against the corresponding side walls on the support plate 8. With this structure, the operating plate 402 can slide along the side wall of the support plate 8 by pulling or pushing the upper end of the operating plate 402, thereby obtaining effective support. The running trajectory is not easy to deviate, and precise meshing can be achieved with the rack on the fixed plate 5.

[0028] As attached Figure 4 and Figure 6 As shown, the pressure plate 401 of this application is provided with a slot 404 facing downwards. The slot 404 is used to hook onto the bearings 9 at both ends of the upper glue roller 2. Specifically, the pressed part on the bearing 9 of the upper glue roller 2 is a round shaft structure, and the contour of the corresponding slot 404 is exactly matched with the outer diameter of the round shaft. So after the two are hooked and locked, a stable pressing can be achieved on the film-coating roller, and they are not easy to slip or misalign.

[0029] As attached Figure 3-4As shown, the bearing 9 described in this application is provided with a radial annular groove 901, and the slot 404 engages with the radial annular groove 901. Specifically, the bearing 9 is rotatably sleeved on the shaft of the rubber roller. Two axially parallel radial annular grooves 901 can be provided on the bearing 9 at each end of the upper rubber roller 2 in the axial direction. The radial annular groove 901 at the outer end is used to engage with the slot 404 of the operating plate 402, and the radial annular groove 901 at the inner end engages with and supports the support plate 8. The radial annular groove 901 forms limiting blocks for the pressure plate 401 on both sides along the thickness direction of the slot 404 in the axial direction. This allows the operating plate to engage with the slot 404 after it engages with the radial annular groove 901. 402 is axially limited within the radial annular groove 901 to prevent axial displacement and ensure the stability of the pressing position and the locking force. A notch is provided on the support plate 8 at the position for engaging with the radial annular groove 901 on the upper rubber roller 2, and the two are engaged from the notch. A through hole adapted to the outer diameter of the radial annular groove 901 is provided on the support plate 8 at the position for engaging with the radial annular groove 901 on the lower rubber roller 3. The bearing 9 here can be set as a split structure, that is, two parts located on the inner and outer sides in the thickness direction of the support plate 8. The two parts can be screwed together on the left and right sides in the thickness direction of the support plate 8 by means of threaded connection. The two ends of the rubber roller can be rotated and fitted into the axial through hole of the bearing 9.

[0030] As attached Figure 2-5 and Figure 7 As shown, the fixing plate 5 described in this application is provided with an inclined reinforcing rib 502, which is disposed opposite to the rack 501. Specifically, a reinforcing rib 502 is provided on the fixing plate 5 along its length in the upper and lower directions, and the reinforcing rib 502 gradually becomes wider from top to bottom. With this structure, the stability of the fixing plate 5 in the push-pull process of the operating plate 402 can be improved, and it is not easy to shake or deviate, thereby improving the accuracy of the meshing position.

[0031] As attached Figure 4-5 As shown, the bottom of the operating plate 402 described in this application is provided with a first hook 405, and the corresponding base plate 7 is provided with a second hook 701. The elastic element 6 is a spring with hooks at both ends, so that the two ends of the elastic element 6 are respectively hooked to the first hook 405 and the second hook 701. Specifically, the elastic element 6 is a tension spring structure, and the hooks at both ends of its length direction correspond to the first hook 405 and the second hook 701 to achieve hook connection. The elastic element 6 always has an elastic elongation deformation force between the two. With this structure, the elastic element 6 can be stably connected between the base plate 7 and the operating plate 402, which can provide sufficient elastic pulling force to the operating plate 402 during the pushing and pulling process, and achieve stable engagement with the rack 501 on the fixed plate 5.

[0032] As attached Figure 6 As shown, the operating plate 402 and the adjusting tooth 403 of this application extend in the same straight line in the vertical direction; that is, their vertical extension directions are on the same straight line. With this structure, when the operating plate 402 is pushed or pulled, the adjusting tooth 403 can be pulled more directly to slide on the rack 501, so as to achieve meshing and positioning of the two at different positions and it is not easy for them to deviate.

[0033] As attached Figure 2-5 As shown, a set of pressure adjustment mechanisms is symmetrically arranged at both ends of the upper glue roller 2 in the axial direction of this application. Specifically, this application has two sets of upper and lower glue rollers, so four sets of pressure adjustment mechanisms are arranged. With this structure, both ends of the upper glue roller can be adjusted to maintain the balance of pressure adjustment between the entire upper glue roller 2 and the lower glue roller 3, and ensure the sealing quality.

[0034] As attached Figure 1-5 This application also provides a laminator, which includes the roller pressing adjustment mechanism described above. With this laminator, the pressure adjustment between the upper and lower rollers can be directly adjusted by pushing and pulling the force application part from above the machine body, without needing to flip the laminator, making operation convenient. Furthermore, since this application achieves pressure adjustment and stabilization through rack and pinion engagement, the pressure is more stable compared to the simple spring-assisted push of existing technologies.

[0035] The roller pressing adjustment mechanism described in this application uses a conventional roller structure with parallel upper and lower rollers in existing laminating machines. The main innovation lies in the pressure adjustment structure, which adjusts the pressure between the upper roller 2 and the lower roller 3 by directly acting on the upper part of the operating plate 402 extending from the upper part of the laminating machine body 1. Therefore, the adjustment process does not require flipping the laminating machine, making operation more convenient and faster. Furthermore, the roller pressing adjustment mechanism uses a combination of a rack and pinion and an elastic element 6. This structure adjusts the pressure between the upper roller 2 and the lower roller 3 by adjusting the position of the adjusting teeth 403 on the rack 501, thus maintaining stable pressure. Simultaneously, the elastic element 6 pulls the operating plate 402 to prevent excessive movement in the upper and lower directions. This structure ensures that the adjusted pressure is less prone to change and the adjusted state is more stable.
