Description

Technical Field

[0001] This utility model relates to the technical field of label die-cutting equipment, specifically a label tape die-cutting pressure control device. Background Technology

[0002] In the label tape manufacturing industry, die-cutting is a crucial step in ensuring product quality and production efficiency. Currently, there are two main types of label tape die-cutting pressure control devices on the market. One type uses a fixed pressure setting, where a fixed pressure value is set based on experience before production, and the pressure remains constant throughout the entire production process. The other type requires manual pressure adjustment after stopping the machine. When operators find the die-cutting effect unsatisfactory or change materials, they need to stop the production line and adjust the pressure by adjusting mechanical parts (such as nuts, screws, etc.).

[0003] However, these traditional methods have many drawbacks. Because the materials used in label tape production are widely available, their physical properties, such as thickness, hardness, and flexibility, vary significantly. Furthermore, different batches of labels have vastly different requirements in terms of shape, size, and precision. When the material thickness changes, the fixed-pressure device cannot adapt, easily resulting in labels not being cut properly or being over-cut, leading to material waste and substandard product quality. For manually adjustable pressure devices, the operation is cumbersome and time-consuming, requiring machine shutdown for each adjustment, severely impacting production efficiency. To enable real-time adjustment of die-cutting pressure during production, thereby improving product quality and production efficiency, we propose a label tape die-cutting pressure control device.

[0017] Beneficial effects

[0018] This invention provides a label tape die-cutting pressure control device. Compared with the prior art, it has the following advantages:

[0019] 1. This label features a die-cutting pressure control device. A drive motor rotates two sets of crankshafts synchronously. Through linkage transmission and sliding column limiting, the top plate and upper template move up and down for die-cutting. During the die-cutting process, the operator can start and adjust the motor in real time. Through the transmission of drive gears, driven gears, threaded sleeves, and adjusting screws, the die-cutting pressure is adjusted to achieve the best die-cutting effect. This allows for real-time adjustment of die-cutting pressure during production, improving product quality and production efficiency.

[0020] 2. This label tape die-cutting pressure control device uses a lifting motor to drive a bidirectional screw to rotate, controlling the two sets of moving blocks to move closer or further apart, thereby raising and lowering the lower template and adjusting the label tape tension to ensure it always fits the lower template, preventing gaps from affecting the die-cutting quality.

[0021] 3. This label tape die-cutting pressure control device uses the elastic force of the second spring on the connecting frame during the die-cutting process to keep the pressure roller tightly against the surface of the label tape. As the label tape conveying pressure roller rotates, any possible warping edges are flattened to ensure product quality. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a label tape die-cutting pressure control device, including a workbench 1, a lower template 17 slidably connected to the inner wall of the workbench 1, several sets of sliding columns 4 fixedly connected to the top of the workbench 1, a top plate 15 slidably sleeved on the outside of the sliding columns 4, an installation cover 27 fixedly connected to the bottom of the top plate 15, an upper template 19 provided at the bottom of the installation cover 27, a die-cutting component for die-cutting the label tape installed on the workbench 1, a lifting component for driving the lower template 17 to rise and fall, and a flattening component for flattening the label tape installed on the workbench 1;

[0031] The die-cutting assembly includes a mounting frame 3, which is fixedly connected to the top of the worktable 1. Two sets of crankshafts 8 are rotatably mounted on the mounting frame 3. Several sets of connecting rods 14 are hinged to the top of the top plate 15. The upper ends of the connecting rods 14 are rotatably connected to the crankshafts 8. A drive motor 9 is fixedly mounted on the mounting frame 3. The output end of the drive motor 9 is fixedly connected to one set of crankshafts 8. The front ends of the two sets of crankshafts 8 are fixedly connected to pulleys 7. A belt is tensioned between the two sets of pulleys 7. An adjustment mechanism for adjusting the die-cutting pressure is installed on the mounting cover 27.

[0032] In use, the label tape is laid flat on the upper surface of the lower template 17 and conveyed by the conveyor structure. The height of the lower template 17 can be adjusted by the lifting component, thereby adjusting the tension of the label tape to a certain extent, so that the label tape always adheres to the surface of the lower template 17 and prevents the label tape from affecting the die-cutting quality due to a certain gap between the label tape and the lower template 17. The drive motor 9 is started, and the two crankshafts 8 rotate synchronously under the action of the pulley 7. Through the transmission of the connecting rod 14 and the limiting action of the sliding column 4, the rotation of the crankshaft 8 is converted into the up and down movement of the top plate 15, which drives the mounting cover 27 and the upper template 19 to move up and down. The label tape is die-cut by the upper template 19. According to the actual die-cutting effect, the operator can adjust the distance between the upper template 19 and the mounting cover 27 in real time during the die-cutting process through the adjustment mechanism, thereby adjusting the distance between the upper template 19 and the lower template 17, which is to adjust the die-cutting pressure to achieve the best die-cutting effect. This allows for real-time adjustment of the die-cutting pressure during the production process, improving product quality and production efficiency. During the die-cutting process, the label tape may stick to the upper template 19, which may cause some labels to curl up after die-cutting. The flattening component can flatten any curled edges to ensure product quality.

[0033] The adjustment mechanism includes a drive gear 26, which is rotatably connected to the bottom of the inner cavity of the mounting cover 27. Several sets of threaded sleeves 30 are rotatably connected to the bottom of the inner cavity of the mounting cover 27. A driven gear 31 is fixedly sleeved on the outside of the threaded sleeve 30. The driven gear 31 meshes with the drive gear 26. Several sets of adjusting screws 32 are fixedly connected to the top of the upper template 19. The adjusting screws 32 slide through the mounting cover 27 and are threadedly connected to the threaded sleeves 30. An adjusting motor 10 is fixedly installed on the top of the top plate 15. The output end of the adjusting motor 10 is fixedly connected to the drive gear 26.

[0034] When the adjusting motor 10 is started, it drives the drive gear 26 to rotate, which in turn causes the driven gear 31 to rotate. This causes the threaded sleeve 30 to rotate, and under the action of the adjusting screw 32, the upper template 19 moves up and down, thereby adjusting the distance between the upper template 19 and the mounting cover 27.

[0035] The sliding column 4 is fitted with a first spring 5. The bottom of the first spring 5 is fixedly connected to the top of the worktable 1, and the top of the first spring 5 is fixedly connected to the bottom of the top plate 15. The top of the sliding column 4 is fixedly connected to a limit block 11.

[0036] When the upper template 19 moves downward, the first spring 5 can reduce the collision force between the upper template 19 and the lower template 17, play a certain buffering role, and extend the service life of the device. The limiting block 11 is used to limit the position of the top plate 15 and prevent the top plate 15 from disengaging from the sliding column 4.

[0037] The lifting assembly includes several sets of fixed blocks 18, which are fixedly connected to the bottom of the lower template 17. Two sets of moving blocks 21 are slidably connected to the bottom of the inner cavity of the worktable 1. The bottom of the fixed block 18 is provided with a first inclined surface, and the top of the moving block 21 is provided with a second inclined surface that matches the first inclined surface. A power mechanism that drives the two sets of moving blocks 21 to move is installed on the worktable 1.

[0038] The power mechanism includes a lifting motor 12, which is fixedly installed on the right side of the workbench 1. A bidirectional screw 28 is rotatably connected to the inner wall of the workbench 1. The bidirectional screw 28 is threaded through the moving block 21. The output end of the lifting motor 12 is fixedly connected to the bidirectional screw 28.

[0039] The lifting motor 12 is started, which drives the bidirectional screw 28 to rotate, causing the two sets of moving blocks 21 to move closer or further apart. Under the interaction of the first inclined plane and the second inclined plane, when the two sets of moving blocks 21 move further apart, the lower template 17 moves upward. When the two sets of moving blocks 21 move closer together, the lower template 17 moves downward. By controlling the lifting and lowering of the lower template 17, the tension of the label tape can be adjusted to a certain extent, so that the label tape always adheres to the surface of the lower template 17, preventing the die-cutting quality from being affected by a certain gap between the label tape and the lower template 17.

[0040] Two sets of limiting strips 13 are fixedly connected to the top of the worktable 1, and a guide slope is provided at the left end of the limiting strip 13. This can limit the position of the label tape during the die-cutting process and prevent the label tape from shifting.

[0041] The flattening assembly includes a fixed frame 6, which is fixedly connected to the top of the workbench 1. A connecting plate 16 is fixedly installed on the fixed frame 6. Several sets of second springs 29 are fixedly connected to the bottom of the connecting plate 16. A connecting frame 23 is fixedly connected to the bottom of the second springs 29. A pressure roller 22 is rotatably installed on the connecting frame 23. The bottom of the pressure roller 22 abuts against the top of the lower template 17. A stabilizing mechanism is installed on the connecting plate 16 to prevent the pressure roller 22 from swaying left and right.

[0042] During the die-cutting process, the label tape may stick to the upper template 19, which may cause some labels to curl up after die-cutting. The second spring 29 makes the pressure roller 22 stick tightly to the surface of the label tape by the elastic force of the connecting frame 23. As the label tape is conveyed, the pressure roller 22 rotates and evenly presses over the surface of the label tape to flatten any curled edges and ensure product quality.

[0043] The stabilizing mechanism includes an upper connecting cover 24, which is fixedly connected to the bottom of the connecting plate 16. A lower connecting cover 25 is slidably connected to the inner wall of the upper connecting cover 24, and the bottom of the lower connecting cover 25 is fixedly connected to the top of the connecting frame 23.

[0044] This makes the pressure roller 22 and the connecting frame 23 more stable when moving up and down, and at the same time prevents the second spring 29 from being stuck by debris.

[0045] The outer surface of the pressure roller 22 is covered with an elastic rubber layer, and the surface of the elastic rubber layer is provided with several evenly distributed anti-slip patterns.

[0046] The workbench 1 is fixedly connected to the front and rear sides with support frames 2. The support frames 2 have several sets of mounting holes and shock-absorbing rubber pads at the bottom.

[0047] Working principle: In use, the label tape is laid flat on the upper surface of the lower template 17 and conveyed by the conveying structure. The lifting motor 12 is started to drive the bidirectional screw 28 to rotate, which drives the two sets of moving blocks 21 to move closer or further apart. Under the interaction of the first inclined plane and the second inclined plane, when the two sets of moving blocks 21 move away from each other, the lower template 17 moves upward. When the two sets of moving blocks 21 move closer to each other, the lower template 17 moves downward. By controlling the lifting and lowering of the lower template 17, the tension of the label tape can be adjusted to a certain extent, so that the label tape always adheres to the surface of the lower template 17, preventing the die-cutting quality from being affected by a certain gap between the label tape and the lower template 17. Start the drive motor 9, and under the action of the pulley 7, the two crankshafts 8 rotate synchronously. Through the transmission of the connecting rod 14 and the limiting action of the sliding column 4, the rotation of the crankshaft 8 is converted into the up and down movement of the top plate 15, which drives the mounting cover 27 and the upper template 19 to move up and down. The label tape is die-cut through the upper template 19. According to the actual die-cutting effect, the operator can start the adjusting motor 10 in real time during the die-cutting process to drive the drive gear 26 to rotate, so that the driven gear 31 rotates, and the threaded sleeve 30 rotates. Under the action of the adjusting screw 32, the upper template 19 moves up and down, which can adjust the distance between the upper template 19 and the mounting cover 27, thereby adjusting the distance between the upper template 19 and the lower template 17, which is to adjust the die-cutting pressure to achieve the best die-cutting effect. This allows for real-time adjustment of the die-cutting pressure during the production process, improving product quality and production efficiency. During the die-cutting process, the label tape may stick to the upper template 19, which may cause some labels to curl up after die-cutting. The second spring 29 makes the pressure roller 22 stick tightly to the surface of the label tape by the elastic force of the connecting frame 23. As the label tape is conveyed, the pressure roller 22 rotates and evenly presses over the surface of the label tape to flatten any curled edges and ensure product quality.
