Other industries: such as logistics, warehousing and other fields, used to make labels and signs; The rollers of the existing PP film self-adhesive lamination mechanism cannot adjust their length according to the width of the material, which limits its application range. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides a PP film self-adhesive lamination mechanism, which effectively solves the problem that the rollers of the existing PP film self-adhesive lamination mechanism cannot adjust their length according to the width of the material, thus limiting their application range.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a PP film self-adhesive lamination mechanism, comprising a worktable, with support legs fixedly installed at the four corners of the bottom of the worktable, a support frame fixedly installed at the top of the worktable, two support arms fixedly installed on the upper part of one side of the support frame, a linear slide rail fixedly installed between the two support arms, a support column driven at the bottom of the linear slide rail, a support plate fixedly installed at the bottom of the support column, a cylinder fixedly installed in the middle of the bottom of the support plate, a hollow strip fixedly installed at the transmission end of the cylinder, and movable frames slidably installed at both ends inside the hollow strip, with the two movable frames close to each other. Each end cap is rotatably mounted on one side. Four inserts are fixedly mounted on the side of each end cap that is close to each other. A roller body is located between the two end caps. Each end of the two roller bodies has four slots. Eight inserts are inserted into the four slots. Sliders are fixedly mounted on both sides of the eight inserts. Sliders are slidably mounted inside the slides on the inner walls of both sides of the eight slots. A drive motor is fixedly mounted at the bottom inside the roller body. A transmission component is provided at the output end of the drive motor. The transmission component is connected to the two end caps. When the drive motor is running, it outputs power to the two end caps through the transmission component.
[0005] Preferably, limit rods are fixedly installed at both ends of the top of the hollow strip, and limit sleeves are fixedly installed on both sides of the top of the support plate, with the two limit rods inserted into the inside of the two limit sleeves.
[0006] Preferably, the transmission assembly includes a driving bevel gear, which is fixedly installed at the output end of the drive motor. A driven bevel gear is meshed with one side of the surface of the driving bevel gear. A shaft is fixedly installed in the middle of the driven bevel gear. Threaded rods are fixedly installed at both ends of the shaft. Rotating frames are rotatably installed at the ends of the two threaded rods that are far apart from each other. All four ends of the two rotating frames are fixedly connected to the inner wall of the roller body.
[0007] Preferably, the surface of the threaded rod is threaded with threaded sleeves, and support rods are fixedly installed on the upper and lower parts of the two threaded sleeves. One end of the four support rods is fixedly connected to the side of the two end caps that are close to each other.
[0008] Preferably, sliding sleeves are fixedly installed on both sides of the two threaded sleeves, and sliding rods are inserted between the interiors of the two sliding sleeves on the same side. Fixed heads are fixedly installed at both ends of the two sliding rods, and one end of each of the four fixed heads is fixedly connected to the inner wall of the roller body.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator places the material on the top of the workbench and coats it, then starts the drive motor to drive the active bevel gear to rotate. When the active bevel gear rotates, it drives the shaft to rotate through the driven bevel gear. When the shaft rotates, it drives the two threaded rods to rotate along the two rotating frames. When the two threaded rods rotate, they drive the two threaded sleeves to move back to back. When the two threaded sleeves move back to back, they both drive the sliding sleeves to slide along the surface of the sliding rod, which increases the stability of the two threaded sleeves when they move. When the two threaded sleeves move back to back, they both drive the two end caps to move back to back through the two support rods. When the two end caps move back to back, they both drive the insert to extend outward along the inside of the slot. When the insert moves, it drives the slider to slide along the inside of the groove, which increases the stability of the insert when it moves. Thus, the roller body can be lengthened.
[0010] Next, the operator activates the cylinder to move the hollow strip downwards. As the hollow strip moves downwards, it causes two limit rods to slide along the inside of two limit sleeves, increasing the stability of the hollow strip during downward movement. The downward movement of the hollow strip also causes two end caps to move downwards via two moving frames. These end caps, in turn, cause the roller body to move downwards, pressing down on the material. Then, the operator drives the linear guide rail to move the support column and support plate. As the support plate moves, the cylinder moves the hollow strip. The movement of the hollow strip, in turn, causes the two end caps to move via two moving frames. The movement of the end caps, in turn, causes the roller body to roll and press the coated material through the insert strip. This allows the rollers of this PP film self-adhesive laminating mechanism to quickly and easily adjust their length according to the width of the material, thus greatly increasing its applicability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Depend on Figures 1 to 5 The present invention includes a workbench 1, with support legs 2 fixedly installed at the four corners of the bottom of the workbench 1, a support frame 3 fixedly installed at the top of the workbench 1, two support arms 4 fixedly installed on the upper part of one side of the support frame 3, a linear slide rail 5 fixedly installed between the two support arms 4, a support column 6 drivenly installed at the bottom of the linear slide rail 5, a support plate 7 fixedly installed at the bottom of the support column 6, a cylinder 8 fixedly installed at the middle of the bottom of the support plate 7, a hollow strip 9 fixedly installed at the transmission end of the cylinder 8, and movable frames 12 slidably installed at both ends inside the hollow strip 9, a head 13 rotatably installed on the side of the two movable frames 12 that are close to each other, four inserts 15 fixedly installed on the side of the two head 13 that are close to each other, and a roller body 14 provided between the two head 13. Each of the two roller bodies 14 has four slots 19 at both ends, and eight inserts 15 are inserted into the four slots 19. Each of the eight inserts 15 has a slider 18 fixedly installed on both sides. Each of the eight slots 19 has a groove 17 on the inner wall of both sides, and the sliders 18 are slidably installed in the groove 17. A drive motor 16 is fixedly installed at the bottom inside the roller body 14. The output end of the drive motor 16 is equipped with a transmission component, which is connected to the two end caps 13. When the drive motor 16 is running, it outputs power to the two end caps 13 through the transmission component. Limiting rods 10 are fixedly installed at both ends of the top of the hollow strip 9, and limiting sleeves 11 are fixedly installed on both sides of the top of the support plate 7. The two limiting rods 10 are inserted into the two limiting sleeves 11.
[0021] In use, the operator places the material on the top of the workbench 1 and coats it. Then, the drive motor 16 is started to drive the transmission component to run. When the transmission component runs, it drives the two end caps 13 to move back to back. When the two end caps 13 move back to back, they both drive the insert strip 15 to extend outward along the inside of the slot 19. When the insert strip 15 moves, it drives the slider 18 to slide along the inside of the slide groove 17, which increases the stability of the insert strip 15 when it moves, thereby lengthening the roller body 14.
[0022] Next, the operator activates cylinder 8 to move the hollow strip 9 downwards. As the hollow strip 9 moves downwards, it causes the two limit rods 10 to slide along the inside of the two limit sleeves 11, increasing the stability of the hollow strip 9 during downward movement. When the hollow strip 9 moves downwards, it drives the two end caps 13 to move downwards via the two moving frames 12. The two end caps 13 then drive the roller body 14 to move downwards and press the material. Then, the operator drives the linear slide rail 5 to move the support column 6 and the support plate 7. When the support plate 7 moves, it drives the hollow strip 9 to move via cylinder 8. When the hollow strip 9 moves, it drives the two end caps 13 to move via the two moving frames 12. When the two end caps 13 move, they drive the roller body 14 to roll and press the coated material via the insert strip 15. This allows the roller of this PP film self-adhesive laminating mechanism to quickly and conveniently adjust its length according to the width of the material, thereby greatly increasing its applicability.
[0023] The transmission assembly includes a driving bevel gear 20, which is fixedly installed at the output end of the drive motor 16. A driven bevel gear 21 is meshed with one side of the surface of the driving bevel gear 20. A shaft 22 is fixedly installed in the middle of the driven bevel gear 21. Threaded rods 23 are fixedly installed at both ends of the shaft 22. Rotating frames 27 are rotatably installed at the ends of the two threaded rods 23 that are far apart from each other. The four ends of the two rotating frames 27 are fixedly connected to the inner wall of the roller body 14. Threaded sleeves 29 are threadedly connected to the surface of the threaded rods 23. Support rods 28 are fixedly installed at the upper and lower parts of the two threaded sleeves 29. One end of the four support rods 28 is fixedly connected to the side of the two end caps 13 that are close to each other. Sliding sleeves 24 are fixedly installed on both sides of the two threaded sleeves 29. Sliding rods 25 are inserted between the interiors of the two sliding sleeves 24 on the same side. Fixed heads 26 are fixedly installed at both ends of the two sliding rods 25. One end of the four fixed heads 26 is fixedly connected to the inner wall of the roller body 14.
[0024] When the drive motor 16 is running, it drives the active bevel gear 20 to rotate. When the active bevel gear 20 rotates, it drives the shaft 22 to rotate through the driven bevel gear 21. When the shaft 22 rotates, it drives the two threaded rods 23 to rotate along the two rotating frames 27. When the two threaded rods 23 rotate, they drive the two threaded sleeves 29 to move backward. When the two threaded sleeves 29 move backward, they both drive the sliding sleeve 24 to slide along the surface of the sliding rod 25, which increases the stability of the two threaded sleeves 29 when they move backward. When the two threaded sleeves 29 move backward, they both drive the two end caps 13 to move backward through the two support rods 28.
