Description

Technical Field

[0001] This utility model belongs to the field of die-cutting technology, specifically relating to a novel asynchronous die-cutting device for adhesive tape. Background Technology

[0002] In the tape production and processing industry, the cutting process is a crucial step determining product quality, production efficiency, and meeting diverse market demands. Traditional tape cutting die technology has evolved over a long period, resulting in several relatively mature models. Synchronous rotary dies are an improvement on fixed dies. They mount the die on a rotating shaft, which rotates synchronously with the tape's conveyor speed. This ensures that the cutting point remains relatively stationary relative to the tape during cutting, achieving more precise cuts. Synchronous rotary dies improve cutting quality and production efficiency to a certain extent, and are particularly suitable for tape products requiring high cutting precision, such as electronic tapes and medical tapes. However, synchronous rotary dies also present some insurmountable problems. Firstly, the die assembly is typically a single, fixed design, with the number and spacing of the blades predetermined during manufacturing, making flexible adjustments impossible based on actual production needs. If tape products with different spacings are required, custom-made dies are necessary, increasing equipment investment and inventory management costs. On the other hand, the rotating shaft and die assembly of synchronous rotating die-cutting molds are usually an integrated structure, making the installation and disassembly process more complicated. When the die-cutting mold wears out or needs to be replaced, it takes a lot of time and manpower, affecting the continuity of production. Utility Model Content

[0003] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a novel asynchronous die-cutting device for adhesive tape. This device aims to solve the problem that in existing synchronous rotating dies, the rotating shaft and die-cutting assembly are usually an integrated structure, which makes the installation and disassembly process complex. When the die-cutting wears out or needs to be replaced, it requires a lot of time and manpower, affecting the continuity of production.

[0004] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a novel asynchronous die-cutting device for adhesive tape, including a mounting base, a rotating shaft, and die-cutting assemblies. The mounting bases are symmetrically distributed on both sides of the rotating shaft and are detachably connected to the rotating shaft. Multiple sets of die-cutting assemblies are equidistantly distributed on the outside of the rotating shaft. Each die-cutting assembly includes a die holder and a blade. The die holder is a disc-shaped structure and is sleeved on the outside of the rotating shaft. The blade is fixed on the outside of the die holder. Dimension lines are provided on the outer wall of the rotating shaft.

[0005] Preferably, the mounting base has a connecting shaft protruding from its surface facing the rotation axis.

[0006] Preferably, the connecting shaft has a mounting groove, and the end of the rotating shaft has a protruding mounting block that is adapted to the mounting groove.

[0007] Preferably, the connecting shaft is externally mounted with mounting bolts, and the mounting block has threaded holes, with the mounting bolts being adapted to the threaded holes.

[0008] Preferably, an inner groove is horizontally formed on the outer wall of the rotating shaft, and a slider is protruding from the inner wall of the tool holder, the slider being slidably installed with the inner groove.

[0009] Preferably, a fixing bolt is installed on the tool holder, the fixing bolt threaded through the slider, and the inner wall of the inner groove has multiple insertion holes, the end of the fixing bolt being adapted to the insertion holes.

[0010] Preferably, the multiple insertion holes are arranged in a straight line along the inner wall of the inner groove.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention offers flexible and adjustable cutting dimensions. Through the sliding engagement of the slider inside the cutter holder with the inner groove on the rotating shaft, and the fixing method of the fixing bolts and insertion holes, operators can easily adjust the position of the die assembly on the rotating shaft according to different production needs, thereby flexibly changing the cutting dimensions and the spacing between the die assemblies. Unlike traditional synchronous rotating die assemblies, it eliminates the need for custom-made dies of different specifications, greatly improving the equipment's versatility and flexibility, meeting diverse market demands, and reducing equipment investment and inventory management costs.

[0012] The mounting base and rotating shaft are detachably connected. The mounting block and mounting slot provide positioning, while the mounting bolts and threaded holes ensure easy and quick installation and removal of the rotating shaft. When the die-cutting mold wears out or needs replacement, simply unscrew the mounting bolts and remove the rotating shaft to replace or maintain the die-cutting mold assembly. This significantly saves time and manpower, improving production continuity and efficiency. Attached Figure Description

[0016] 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.

[0017] This specific embodiment is a novel asynchronous die-cutting device for adhesive tape, and its structural schematic diagram is shown below. Figure 1 As shown, it includes a mounting base 1, a rotating shaft 2, and a die-cutting assembly 4. The mounting base 1 is symmetrically distributed on both sides of the rotating shaft 2. The mounting base 1 and the rotating shaft 2 are detachably connected. Multiple sets of die-cutting assemblies 4 are distributed at equal intervals on the outside of the rotating shaft 2. Multiple insertion holes are arranged in a straight line along the inner wall of the inner groove 11.

[0018] Reference Figure 3 The die assembly 4 includes a die holder 6 and a blade 8. The die holder 6 is a disc-shaped structure and is sleeved on the outside of the rotating shaft 2. The blade 8 is fixed on the outside of the die holder 6. A fixing bolt 5 is installed on the die holder 6. The fixing bolt 5 is threaded through the slider 7. The inner wall of the inner groove 11 has multiple insertion holes. The end of the fixing bolt 5 is adapted to the insertion hole.

[0019] Reference Figure 2 , Figure 4 A dimension line 12 is provided on the outer wall of the rotating shaft 2. A connecting shaft 3 protrudes from the surface of the mounting base 1 facing the rotating shaft 2. The connecting shaft 3 has a mounting groove 10, and a mounting block 15 protrudes from the end of the rotating shaft 2, which is adapted to the mounting groove 10. A mounting bolt 9 is installed on the outside of the connecting shaft 3, and a threaded hole 14 is opened on the mounting block 15, which is adapted to the mounting bolt 9. An inner sliding groove 11 is horizontally opened on the outer wall of the rotating shaft 2, and a slider 7 protrudes from the inner wall of the tool holder 6, which is slidably installed with the inner sliding groove 11.

[0020] Working principle: When using this new asynchronous die-cutting device, first align the mounting blocks 15 at both ends of the rotating shaft 2 with the mounting grooves 10 of the connecting shaft 3 on the mounting base 1, so that the mounting blocks 15 are embedded in the mounting grooves 10, achieving initial positioning of the rotating shaft 2 and the mounting base 1. Then, pass the mounting bolts 9 through the connecting shaft 3 and screw them into the threaded holes 14 on the mounting blocks 15, and securely install the rotating shaft 2 between the two mounting bases 1 through bolt connection, completing the overall installation of the device. After that, start the equipment to make the rotating shaft 2 start rotating.

[0021] Because the slider 7 on the inner wall of the cutter holder 6 is slidably installed with the inner groove 11 on the outer wall of the rotating shaft 2, the operator can push the cutter holder 6 according to the actual cutting size requirements of the tape in production, causing the slider 7 to slide within the inner groove 11, thereby changing the position of the die assembly 4 on the rotating shaft 2. The dimension line 12 on the outer wall of the rotating shaft 2 can provide the operator with a precise dimensional reference, ensuring the accuracy of the spacing adjustment of the die assembly 4. After the cutter holder 6 is moved to the appropriate position, the fixing bolt 5 is threaded through the slider 7, and its end is inserted into the corresponding insertion hole on the inner wall of the inner groove 11, thereby fixing the cutter holder 6 to the rotating shaft 2 and ensuring that the die assembly 4 will not be displaced during the rotation of the rotating shaft 2.

[0022] Driven by the rotation of the rotating shaft 2, the die-cutting assembly 4 rotates accordingly. Simultaneously, the conveyor belt is fed at a certain speed, interacting with the rotating die-cutting assembly 4, and the blade 8 cuts the conveyor belt. Parameters such as the rotation speed can be flexibly adjusted according to the actual conveyor belt feeding conditions, better adapting to the tape cutting needs of different speeds and motion trajectories, achieving efficient and precise cutting.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
