Description

Technical Field

[0001] This utility model relates to the field of paper lamination technology, and in particular to a removable support shaft module and a lamination machine. Background Technology

[0002] To enhance the gloss of printed paper and prevent ink from blurring after printing, some papers printed with various patterns or colors require a plastic film coated with adhesive to be heated and bonded together, forming a paper-plastic composite laminated product. This laminated paper not only improves the gloss and durability of the printed material but also extends its lifespan. A laminating machine is required for this lamination process.

[0003] During the gluing process, existing gluing mechanisms typically use a gluing roller and a support roller. The paper passes through the gap between the support roller and the gluing roller, and the glue on the gluing roller coats the paper. After a certain period of use, if a different glue is used, the glue on the surface of the support roller needs to be cleaned to prevent sticking. Existing support rollers are fixed inside the gluing machine by a transmission mechanism, which requires unscrewing a large number of screws when disassembling, which is extremely inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a detachable support shaft module and a gluing machine to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A removable support shaft module includes a glue-passing roller and a support module that cooperates with the glue-passing roller. The support module includes a support roller that is spaced apart from the glue-passing roller and a support seat that movably supports the support roller. The glue-passing roller is equipped with a first drive gear, and the support roller is equipped with a second drive gear that meshes with the first drive gear. The support module also includes a bottom lifting mechanism that drives the support seat to move longitudinally closer to or away from the glue-passing roller.

[0007] Furthermore: the bottom lifting mechanism includes a longitudinally arranged support rod, the top of which is connected to a support base, and the support rod is capable of longitudinal movement.

[0008] Furthermore, the bottom lifting mechanism also includes a drive seat, which has a guide hole for the longitudinal movement of the support rod.

[0009] Furthermore, the bottom lifting mechanism also includes a rotating shaft that can rotate, a drive cam is sleeved on the rotating shaft, and a drive plate is installed at the bottom of the support rod, with the drive cam and drive plate in rolling cooperation.

[0010] Furthermore: a drive handle is fitted onto the outer end of the rotating shaft.

[0011] Furthermore, a compression spring and a tension spring are provided between the support base and the drive base, and the elastic force of the compression spring can drive the support base to approach the rubber roller.

[0012] A gluing machine includes a support shaft module and a pair of spaced-apart guide plates. A gluing roller and a support roller are respectively installed between the two guide plates. The guide plates are formed with disassembly grooves for the support rollers to pass through. There are two support rollers, which are installed at intervals on the top of a support base.

[0013] Furthermore: the support roller includes a roller shaft and a roller body sleeved on the roller shaft, the support seat is formed with a concave rotating groove, the roller shaft rotates in the rotating groove, and a pull ring is installed at the outer end of the roller shaft.

[0014] Furthermore: the roller is provided with a bearing seat, and the support seat is formed with a bearing groove for installing the bearing seat, and the bearing groove is connected to the rotating groove.

[0015] Furthermore: the guide plate is equipped with a longitudinally arranged, rotating adjusting rod, the drive seat is formed with an adjusting hole for the adjusting rod to move through, and the bottom of the adjusting rod is connected to the drive plate.

[0016] The beneficial effects of this utility model are as follows: the glue roller and the support roller achieve synchronous rotation through the meshing transmission of the first drive gear and the second drive gear; when disassembly is required, the bottom lifting mechanism can drive the support seat to move longitudinally closer to or away from the glue roller, the second drive gear installed on the support roller can be separated from the first drive gear, and since the support seat provides movable support for the support roller, the support roller can be pulled out from the support seat, and the support roller can be separated from the glue roller. After being pulled out, the support roller can be cleaned. Disassembly can be achieved without removing screws, which is more efficient and facilitates subsequent installation.

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1-3 As shown, a detachable support shaft module includes a glue-coating roller 11 and a support module 1 that cooperates with the glue-coating roller 11. The support module 1 includes a support roller 13 that is spaced apart from the glue-coating roller 11 and a support seat 22 that movably supports the support roller 13. The glue-coating roller 11 is equipped with a first drive gear 12, and the support roller 13 is equipped with a second drive gear 17 that meshes with the first drive gear 12. The support module 1 also includes a bottom lifting mechanism 2 that drives the support seat 22 to move longitudinally closer to or away from the glue-coating roller 11.

[0031] The glue-coating roller 11 and the support roller 13 rotate synchronously through the meshing transmission of the first drive gear 12 and the second drive gear 17. When disassembly is required, the bottom lifting mechanism 2 can drive the support seat 22 to move longitudinally closer to or away from the glue-coating roller 11. The second drive gear 17 installed on the support roller 13 can be separated from the first drive gear 12. Since the support seat 22 provides movable support for the support roller 13, the support roller 13 can be pulled out from the support seat 22. The support roller 13 can be separated from the glue-coating roller 11. After being pulled out, the support roller 13 can be cleaned. Disassembly can be achieved without removing screws, which is more efficient and facilitates subsequent installation.

[0032] Furthermore, the bottom lifting mechanism 2 includes a longitudinally arranged support rod 21, the top of which is connected to the support base 22, and the support rod 21 is capable of longitudinal movement. The bottom lifting mechanism 2 also includes a drive base 25, which has a guide hole 26 for the longitudinal movement of the support rod 21. A guide sleeve 27 is installed in the guide hole 26, and the support rod 21 can move axially along the guide hole 26 with the guide sleeve 27 installed, so as to drive the support base 22 installed on the top of the support rod 21 to move up and down. The second drive gear 17 installed on the support roller 13 can be disengaged or engaged with the first drive gear 12. After disengagement, the support roller 13 can be directly pulled out from the support base 22 for direct disassembly and cleaning; after cleaning, the support roller 13 is put back into the support base 22, and then the support base 22 is raised. The second drive gear 17 installed on the support roller 13 can engage with the first drive gear 12 for transmission and continue gluing, greatly improving the efficiency of disassembly and cleaning.

[0033] Specifically, the bottom lifting mechanism 2 also includes a rotatable rotating shaft 3, on which a drive cam 31 is fitted. A drive plate 32 is mounted on the bottom of the support rod 21, and the drive cam 31 and drive plate 32 are in rolling engagement. When the rotating shaft 3 rotates, the drive cam 31 rotates. When the protruding part of the drive cam 31 faces downward, it drives the drive plate 32 mounted on the bottom of the support rod 21 to descend. At this time, the support seat 22 connected to the support rod 21 descends synchronously, thereby separating the second drive gear 17 from the first drive gear 12. Disengaging from the transmission, the support roller 13 can then be detached from the support seat 22 without the need for screws, thus greatly improving efficiency.

[0034] A compression spring 28 is sleeved on the support rod 21 between the support base 22 and the drive base 25. The elastic force of the compression spring 28 can drive the support base 22 to approach the glue roller 11. The compression spring 28 can drive the support rod 21 to rise elastically as a whole. When the rotating shaft 3 rotates, the drive cam 31 rotates. When the protrusion of the drive cam 31 faces upward, the drive plate 32 will not be subjected to the force of the drive cam 31. At this time, it will be subjected to the elastic force of the compression spring 28 and rise as a whole. The second drive gear 17 installed on the support base 22 maintains meshing with the first drive gear 12 to achieve paper glue application.

[0035] The bottom lifting mechanism 2 also includes a tension spring connected to the drive plate 32 at the bottom. The top of the tension spring is fixed. When the drive plate 32 is not subjected to the force of the drive cam 31, the tension spring can drive the drive plate 32 to lift elastically, so that the support seat 22 installed on the top of the support rod 21 can maintain support for the support roller 13.

[0036] Furthermore, a drive handle 33 is sleeved on the outer end of the rotating shaft 3. By swinging the drive handle 33, the rotating shaft 3 can rotate, and the drive cam 31 rotates to drive the drive plate 32 to descend, so that the support module 1 descends as a whole.

[0037] In one embodiment, the bottom lifting mechanism 2 further includes a lever module, which includes a fulcrum shaft and a lever component mounted on the fulcrum shaft. The driving end of the lever component extends outward and is connected to a driving handle. The driven end of the lever component cooperates with the driving plate 32. The driven end of the lever component is located at the top of the driving plate 32. When the driven section of the lever component is driven to swing vertically downward by the driving handle, the support module 1 can be lowered as a whole. At this time, the support roller 13 can be removed from the support seat 22 to complete disassembly and cleaning.

[0038] A gluing machine includes a removable support shaft module and a pair of spaced-apart guide plates 30. A gluing roller 11 and a support roller 13 are respectively installed between the two guide plates 30. Each guide plate 30 has a through-hole groove 29 for the support roller 13 to pass through. There are two support rollers 13, spaced apart and installed on top of a support base 22. The through-hole groove 29 allows the support roller 13 to be directly removed during disassembly. The two support rollers 13 form an arc-shaped support structure. After passing through the first support roller 13, the paper continues to pass through the second support roller 13. The two support rollers 13 simultaneously support the paper, increasing the contact area between the paper and the gluing roller 11. During gluing, some gravure paper can be coated with more glue, increasing the coating area and ensuring the quality of the gluing process, preventing localized glue shortages in the glued paper.

[0039] In addition, one or two support rollers 13 can be installed depending on the actual situation of the product.

[0040] Specifically, the support roller 13 includes a roller shaft 14 and a roller body 15 sleeved on the roller shaft 14. The support base 22 is formed with a concave rotating groove 23, within which the roller shaft 14 rotates. A pull ring 36 is installed at the outer end of the roller shaft 14. A bearing seat 16 is sleeved on the roller shaft 14, and the support base 22 is formed with a bearing groove 24 for mounting the bearing seat 16. The bearing groove 24 communicates with the rotating groove 23. When the support roller 13 rotates via the roller shaft 14, the bearing seat 16 rotates and engages with the bearing groove 24, while the roller shaft 14 rotates and engages with the rotating groove 23. Thus, the support base 22 provides rotatable and movable support for the support roller 13, preventing it from becoming fixed. During disassembly, the support roller 13 can be easily separated from the support base 22, greatly improving the efficiency of disassembly and assembly.

[0041] Furthermore, the guide plate 30 is equipped with a longitudinally arranged, rotatable adjusting rod 34, and the drive seat 25 is formed with an adjusting hole 35 through which the adjusting rod 34 moves. The bottom of the adjusting rod 34 is connected to the drive plate 32. The adjusting hole 35 is a threaded hole, and the adjusting rod 34 is formed with an external thread structure that engages with the threaded hole. When the adjusting rod 34 is rotated, it will engage with the adjusting hole 35 of the drive seat 25, and the height of the adjusting rod 34 can be adjusted. When the protruding part of the drive cam 31 is facing upward, the drive plate 32 will not be subjected to the force of the drive cam 31, but will be subjected to the tension of the tension spring. The drive plate 32 is elastically lifted, and the second drive gear 17 installed on the support seat 22 remains engaged with the first drive gear 12. Then, the adjusting rod 34 is rotated to drive the drive plate 32 to rise. The drive plate 32 and the support seat 22 can be kept at the same height to prevent the compression spring 28 from loosening and to ensure that the support roller 13 located on the support seat 22 can maintain engagement with the glue roller 11 to stably apply glue to the paper.
