Description

Technical Field

[0001] This utility model relates to the field of label coating technology, and in particular to a label printing and coating device. Background Technology

[0002] Labels are important carriers for identifying product names, specifications, place of origin, brand and other information. They are widely used in many fields such as commodity packaging, logistics and transportation, industrial production and daily life. However, untreated labels are prone to blurring, fading or even damage during transportation, storage and use due to friction, scratches, contact with water or chemicals. Therefore, it is necessary to cover the surface of the printed label with a protective film.

[0003] In the prior art, after lamination, the label paper is usually wound into rolls for easy storage and transportation. However, during subsequent handling or use, if the operator applies improper force or uneven force when removing the whole roll of label paper from the core, excessive stress concentration can easily occur in local areas of the roll label. This unbalanced stress state can cause the entire label roll to slip relative to each other or even tilt as a whole, resulting in wrinkles, detachment and other damage between the film and the substrate at the edge of the roll, affecting the quality of the finished label. Therefore, this application proposes a label printing and lamination device. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art where uneven force is applied when removing rolls of label paper, which easily causes wrinkles and detachment between the film and the substrate, and to propose a label printing and laminating device.

[0005] The technical solution of this utility model: A label printing and laminating device includes an operating frame. Drive roller one and drive roller three for releasing label paper and film are respectively installed on the inner side of the operating frame. Drive roller two and guide roller are also installed on the outer side of the operating frame. Drive roller two is used to wind up the label paper. The laminating device also includes at least: A baffle is disposed on the outside of the second drive roller, the baffle being used to push the wound label paper away from the outside of the second drive roller; An elastic mechanism, connected to the baffle, is used to drive the baffle to move; A cutting blade for cutting label paper, wherein a fixed block is fixedly connected to the top of the cutting blade, and two sets of guide rods slide through the inside of the fixed block, and lifting blocks are fixedly connected to the outside of the two sets of guide rods; The power mechanism, connected to the lifting block, is used to control the raising and lowering of the cutting blade; The locking mechanism connects the lifting block and the elastic mechanism and is used to control the operation of the elastic mechanism.

[0006] Optionally, the elastic mechanism includes two sets of guide plates, a limiting rod, a fixed plate, and a spring. Both sets of guide plates are fixedly connected to the outer side of the baffle. The limiting rod slides through the interior of the guide plate and is fixedly connected to the inner side of the operating frame. The fixed plate is fixedly connected to the end of the limiting rod away from the operating frame. The spring is fixedly connected between the guide plate and the fixed plate.

[0007] Optionally, the power mechanism includes a cylinder, two sets of recessed frames, and a second limiting rod. The cylinder is installed inside the operating frame, and the output end of the cylinder is connected to the lifting block. Both sets of recessed frames are fixed to the inside of the operating frame. The two ends of the second limiting rod are fixed to the inner wall of the recessed frame, and the second limiting rod slides through the lifting block.

[0008] Optionally, the engaging mechanism includes an L-bar, an inclined block, and a Z-plate. The L-bar is fixed to the outside of the lifting block, the inclined block is fixed to the end of the L-bar away from the operating frame, and the Z-plate is fixed to the outside of the guide plate. The Z-plate and the inclined block are in contact with each other.

[0009] Optionally, a reciprocating mechanism is provided around the fixed block. The reciprocating mechanism is used to drive the fixed block to reciprocate laterally when the fixed block moves up and down, so that the cutting blade rubs back and forth to cut the label paper.

[0017] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 and Figure 2 As shown, the present invention proposes a label printing and laminating device, including an operating frame 1. The inner side of the operating frame 1 is respectively equipped with a drive roller 2 and a drive roller 4 for releasing label paper and film. The drive roller 2 releases the unlaminated label paper. The outer side of the operating frame 1 is also equipped with a drive roller 3 and a guide roller 5. The drive roller 3 is used to wind up the label paper. The drive roller 2 releases the label paper, while the drive roller 3 rewinds it. When the label paper is transferred from the drive roller 2 to the path of the drive roller 3, the drive roller 4 releases the wound film. With the limiting effect of the guide roller 5, the film located outside the drive roller 4 adheres to the label paper, thereby achieving label lamination. It should be noted that the drive rollers 2, 3, and 4 are all conventional technologies in existing laminating devices and are mature technologies, which will not be elaborated further.

[0021] As one implementation method, such as Figure 3 , Figure 4 and Figure 5 As shown, the laminating device includes a baffle 6 disposed outside the drive roller 3. There is a certain gap between the drive roller 3 and the baffle 6, so that the drive roller 3 will not touch the baffle 6 when it rotates. The baffle 6 is used to push the wrapped label paper away from the outside of the drive roller 3. When the baffle 6 is pushed to move away from the operating frame 1, the label paper wrapped outside the drive roller 3 can be moved synchronously, so that the force is more even when the laminated label paper is removed, and wrinkles, detachment and other damages are avoided between the film and the substrate at the edge of the roll. An elastic mechanism is connected to the baffle 6 and is used to drive the baffle 6 to move. The elastic mechanism not only supports the baffle 6, but also provides power for the movement of the baffle 6.

[0022] Furthermore, such as Figure 5 and Figure 6As shown, the laminating device also includes a cutting blade 7 for cutting label paper. When the cutting blade 7 moves downward, it contacts the film, thereby cutting the film. A fixing block 8 is fixedly attached to the top of the cutting blade 7. Two sets of guide rods 9 slide through the interior of the fixing block 8. The fixing block 8 and the guide rods 9 support the cutting blade 7, and the fixing block 8 can drive the cutting blade 7 to move laterally along the outside of the guide rods 9, thereby adjusting the cutting direction of the cutting blade 7. Lifting blocks 10 are fixedly attached to the outside of the two sets of guide rods 9. A power mechanism, connected to the lifting block 10, is used to control the lifting and lowering of the cutting blade 7. The power mechanism provides the cutting blade 7 with the power to move up and down. The power mechanism drives the lifting block 10 to lift and lower, and when the lifting block 10 lifts and lowers, it drives the fixing block 8 to lift and lower through the guide rods 9. The lifting and lowering of the fixing block 8 ultimately drives the cutting blade 7 to lift and lower. When the cutting blade 7 descends, it cuts the film. It should be noted that the cutting blade 7 is made of zirconium oxide, which has extremely high hardness and a smooth and sharp surface, making it suitable for the cutting scenarios required in this embodiment.

[0023] Furthermore, such as Figure 6 As shown, the locking mechanism in the laminating device is connected between the lifting block 10 and the elastic mechanism to control the operation of the elastic mechanism. In the initial state, the elastic mechanism is in a deformation and energy storage state. When the lifting block 10 descends to a certain height, the locking mechanism will release the control of the elastic mechanism, and the elastic mechanism will release its elastic potential energy, thereby pushing the baffle 6 to move, so that the baffle 6 will cause the wrapped label paper to detach from the outside of the drive roller 2 3, making it easier for the operator to pick it up.

[0024] As one implementation method, such as Figure 4 and Figure 5 As shown, the elastic mechanism includes two sets of guide plates 11, a limiting rod 12, a fixed plate 13, and a spring 14. The elastic mechanism is described in detail below: Both sets of guide plates 11 are fixedly connected to the outer side of the baffle 6. The limiting rod 12 slides through the interior of the guide plate 11. The guide plate 11 moves along the outer side of the limiting rod 12, driving the baffle 6 to move. The limiting rod 12 is fixedly connected to the inner side of the operating frame 1. The fixed plate 13 is fixedly connected to the end of the limiting rod 12 away from the operating frame 1. The spring 14 is fixedly connected between the guide plate 11 and the fixed plate 13. In the initial state, under the obstruction of the locking mechanism, the spring 14 is in a stretched deformation state. When the locking mechanism releases the limiting of the guide plate 11, the spring 14 will release elastic potential energy, thereby pulling the guide plate 11 to move away from the operating frame 1. The movement of the guide plate 11 will drive the baffle 6 to move, causing the baffle 6 to push the label roll away from the outer side of the drive roller 3. It should be noted that the label roll will not completely detach from the outer side of the drive roller 3, so there is no risk of the label roll falling to the ground.

[0025] Furthermore, such as Figure 5 and Figure 6 As shown, the power mechanism includes a cylinder 15, two sets of recessed brackets 16, and a limiting rod 17. The power mechanism is described in detail below: The cylinder 15 is installed on the inner side of the operating frame 1, and the operating frame 1 supports the cylinder 15. The output end of the cylinder 15 is connected to the lifting block 10. When the cylinder 15 is running, it will drive the lifting block 10 to move vertically. Both sets of the recessed frames 16 are fixed to the inner side of the operating frame 1. The two ends of the second limiting rod 17 are fixed to the inner wall of the recessed frame 16. The second limiting rod 17 slides through the lifting block 10. At this time, the lifting block 10 will move stably along the outer side of the second limiting rod 17 to prevent the lifting block 10 from shaking.

[0026] Furthermore, such as Figure 5 and Figure 6 As shown, the engaging mechanism includes an L-bar 18, an inclined block 19, and a Z-plate 20. The engaging mechanism is described in detail below: The L-rod 18 is fixed to the outside of the lifting block 10. When the lifting block 10 moves, it will drive the L-rod 18 to move synchronously. The inclined block 19 is fixed to the end of the L-rod 18 away from the operating frame 1. When the L-rod 18 moves, it will drive the inclined block 19 to move synchronously. The Z-plate 20 is fixed to the outside of the guide plate 11. The Z-plate 20 and the inclined block 19 are in contact with each other. As the inclined block 19 moves down, the inclined block 19 will disengage from the contact with the Z-plate 20, that is, the inclined block 19 will disengage from the obstruction of the Z-plate 20. The spring 14 will release elastic potential energy, causing the baffle 6 to push the label roll away from the outside of the drive roller 2 3.

[0027] As one implementation method, such as Figure 7 As shown, a reciprocating mechanism is provided around the fixed block 8. When the fixed block 8 moves up and down, the reciprocating mechanism drives the fixed block 8 to move laterally in a synchronous reciprocating motion, so that the cutting blade 7 rubs back and forth to cut the label paper. When the fixed block 8 moves down, the fixed block 8 will synchronously drive the reciprocating mechanism to run. When the reciprocating mechanism runs, it will drive the fixed block 8 to move laterally in a reciprocating motion. At this time, the fixed block 8 will drive the cutting blade 7 to move laterally in a reciprocating motion. When the cutting blade 7 moves down to squeeze and cut the label paper, it will cooperate with the reciprocating friction of the label paper, thereby improving the cutting efficiency.

[0028] Furthermore, such as Figure 7 As shown, the reciprocating mechanism includes a top plate 21, a connecting rod 22, a square plate 23, and a guide groove 24. The reciprocating mechanism is described in detail below: The top plate 21 is fixed to the top of the fixing block 8. When the fixing block 8 moves down, it will drive the top plate 21 to move down. The connecting rod 22 is fixed to the side of the top plate 21 near the square plate 23. When the top plate 21 moves down, it will drive the connecting rod 22 to move down. The square plate 23 is fixed to the inner side of the operating frame 1. The guide groove 24 is opened on the side of the square plate 23 near the connecting rod 22. The connecting rod 22 is slidably disposed inside the guide groove 24. The guide groove 24 has a wave-shaped design. When the connecting rod 22 moves down, it will move laterally back and forth along the wave shape of the guide groove 24. The lateral movement of the connecting rod 22 is eventually transmitted back to the fixing block 8, causing the fixing block 8 to move laterally along the outer side of the guide rod 9. The lateral reciprocating movement of the fixing block 8 will drive the cutting blade 7 to move laterally back and forth, so that the cutting blade 7 exerts reciprocating friction on the label paper.

[0029] Furthermore, such as Figure 4 As shown, a circular plate 25 is provided around the drive roller 23. A transmission rod 26 is fixedly connected to one end of the circular plate 25 near the operating frame 1. Pressing the circular plate 25 can drive the transmission rod 26 to move towards the side plate 27. The side plate 27 is fixedly connected to the other end of the transmission rod 26 away from the circular plate 25. The side plate 27 is fixed to the outside of the baffle 6. When the transmission rod 26 moves, it will drive the baffle 6 to move through the side plate 27, which makes it easier for the operator to reset the baffle 6.

[0030] In this embodiment, drive roller 2 releases the label paper, while drive roller 3 rewraps it. As the label paper moves from drive roller 2 to drive roller 3, drive roller 4 releases the wound film. With the guidance roller 5's limiting action, the film outside drive roller 4 adheres to the label paper, thus achieving label lamination. At the end of lamination, cylinder 15 lowers lifting block 10. As lifting block 10 descends, it lowers fixed block 8 via guide rod 9. Finally, fixed block 8 descends... The cutting blade 7 will descend, cutting the film. When the fixing block 8 moves down, it will also move the top plate 21 down. The downward movement of the top plate 21 will move the connecting rod 22 down. The downward movement of the connecting rod 22 will cause it to move laterally back and forth along the wave-shaped guide groove 24. The lateral movement of the connecting rod 22 will eventually be transmitted back to the fixing block 8, causing the fixing block 8 to move laterally along the outside of the guide rod 9. The lateral reciprocating movement of the fixing block 8 will cause the cutting blade 7 to move laterally back and forth, so that the cutting blade 7 will exert reciprocating friction on the label paper, improving the cutting efficiency. Furthermore, when the lifting block 10 descends to a certain height, the lifting block 10 will synchronously drive the L rod 18 to move, and the movement of the L rod 18 will synchronously drive the inclined block 19 to move. As the inclined block 19 moves down, the inclined block 19 will disengage from the Z plate 20. The inclined block 19 will disengage from the Z plate 20, and the spring 14 will release its elastic potential energy, thereby pulling the guide plate 11 to move away from the operating frame 1. The movement of the guide plate 11 will drive the baffle 6 to move, causing the baffle 6 to push the label roll away from the outside of the drive roller 2 3.
