Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting tapes, in particular to a composite tape used in the production of acetate cloth. Background Art

[0002] Currently, in industrial production, acetate cloth is a type of cloth-based fiber tape with an adhesive surface on one side, typically used to bond objects like relays, and a fabric surface on the other. To accommodate the structural dimensions of the object being bonded, the acetate cloth typically requires die-cutting, such as punching or cutting.

[0003] In the related art, punching positions and edges are first marked on the acetate cloth, and then the punching positions of the acetate cloth are punched using a circular knife of a die-cutting machine, and the edges of the acetate cloth are cut using an outer frame knife.

[0004] Regarding the above-mentioned related technologies, due to the soft texture of acetate cloth, acetate cloth is prone to failure phenomena such as fuzz, round hole deformation, and fiber cutting during the die-cutting process, resulting in defective products. Therefore, there is a problem of low production yield of acetate cloth.

[0005] In view of this, it is indeed necessary to provide a technical solution for the above-mentioned problems by providing a composite tape for use in acetate cloth production. Utility Model Content

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0020] The following is combined with Figure 1-2 , further details of this application are given.

[0021] The present application provides a composite tape for use in the production of acetate cloth, which adopts the following technical solution:

[0022] Reference Figure 1 and Figure 2 The composite tape includes a base film 1, an acetate cloth 2, a reinforcing strip 3 and a silicone tape 4. The acetate cloth 2 is used as the base material of the tape, with one side of the acetate cloth 2 being the adhesive surface and the other side being the fabric surface. When producing the acetate cloth 2 of corresponding specifications according to the requirements of the object to be adhered, the base film 1 is bonded to the adhesive surface of the acetate cloth 2, serving as a carrier of the acetate cloth 2, forming an isolation layer between the adhesive surface of the acetate cloth 2 and external objects, reducing the adhesion between the adhesive surface of the acetate cloth 2 and external objects, thereby making the movement of the acetate cloth 2 more convenient. The reinforcing strip 3 is placed on the fabric surface of the acetate cloth 2, and the reinforcing strip 3 covers the punching position of the acetate cloth 2. The number of the reinforcing strips 3 is configured according to the punching position of the acetate cloth 2, with the extension direction of the long side or wide side of the acetate cloth 2 as the starting direction, and each row of punching positions along the starting direction corresponds to a reinforcing strip 3. The silicone tape 4 is placed on the side of the acetate cloth 2 close to the reinforcing strip 3, with the adhesive surface of the silicone tape 4 facing the fabric surface of the acetate cloth 2. The silicone tape 4 adheres and fixes the reinforcing strip 3 to the surface of the acetate cloth 2, restricting the relative movement of the reinforcing strip 3 and the acetate cloth 2, making the connection between the reinforcing strip 3 and the acetate cloth 2 tighter.

[0023] When the acetate cloth 2 is die-cut, the reinforcing strip 3 is bonded and fixed to the punching position of the acetate cloth 2 through the silicone tape 4. The reinforcing strip 3 can make the surface of the acetate cloth 2 more compact, make the fibers of the acetate cloth 2 easier to cut, and reduce the generation of burrs. At the same time, the reinforcing strip 3 can also increase the hardness near the circular hole of the acetate cloth 2, reduce the deformation of the circular hole of the acetate cloth 2, and thus increase the yield of the acetate cloth 2.

[0024] Further, refer to Figure 1 and Figure 2The reinforcing strip 3 includes a release film and several fixed hole films 32. The width of the release film is greater than the width of the fixed hole film 32. The release film is located on one side edge of the acetate cloth 2, and the edge of the release film coincides with the edge of the acetate cloth 2. The release film is located at the first row of punching positions at the starting end along the material starting direction. Several fixed hole films 32 are distributed on the surface of the acetate cloth 2 in sequence along the material starting direction. Each fixed hole film 32 corresponds to a row of punching positions. In this embodiment, the long side of the acetate cloth 2 is used as the material starting direction. There are three rows of punching positions on the acetate cloth 2 along the material starting direction, and there are correspondingly configured one release film and two fixed hole films 32. The release film is located in the first row of punching positions along the material starting direction, and the edge of the release film coincides with the edge of the acetate cloth 2. The two fixed hole films 32 correspond to the second and third rows of punching positions in sequence. When the silicone tape 4 is bonded to the surface of the acetate cloth 2, the side edge of the silicone tape 4 is aligned and bonded to the surface of the release film. The edge of the release film extends beyond the edge of the silicone tape 4, so that the edge of the silicone tape 4 is not bonded to the acetate cloth 2, which facilitates the separation of the silicone tape 4 and the acetate cloth 2. Specifically, when the acetate cloth 2 is applied to the object to be adhered, the edge of the release film is lifted from the edge of the acetate cloth 2 to separate the release film from the acetate cloth 2. Driving the release film away from the acetate cloth 2 can further drive the silicone tape 4 bonded to the release film to quickly separate from the acetate cloth 2, reducing the pulling deformation of the acetate cloth 2, thereby reducing the deformation of the acetate cloth 2, and helping to improve the yield rate of the acetate cloth 2.

[0025] Furthermore, both the base film 1 and the reinforcing strips 3 are release films. Release films are silicone release agents applied to the surface of a base film to reduce the film's surface adhesion, providing contact without adhesion or slight adhesion. They can be categorized as PE release films, PET release films, and others, depending on the substrate. In this embodiment, the base film 1 is a blue PET release film, and the reinforcing strips 3 are transparent PET release films. Specifically, a blue PET release film is used as the base film 1, and the surface of the blue PET release film is coated with a silicone oil layer. The silicone oil layer serves as a lubricating layer between the blue PET release film and the acetate cloth 2, so that the base film 1 and the acetate cloth 2 are in contact but not tightly bonded, thereby providing protection for the stickiness of the adhesive surface of the acetate cloth 2, which is beneficial to maintaining the stickiness of the acetate cloth 2, improving the stability of the adhesion between the acetate cloth 2 and the adhered object, and thus increasing the yield of the acetate cloth 2; a transparent PET release film is used as the reinforcing strip 3. The transparent PET release film can not only increase the hardness of the surface of the acetate cloth 2, making the fibers of the acetate cloth 2 easier to cut and reducing the generation of burrs, but also facilitate observation of the punching positions on the acetate cloth 2, improve the accuracy of punching, and help improve the yield of the acetate cloth 2.

[0026] Furthermore, the thickness of the reinforcing strip 3 is 25 μm, and the thickness of the base film 1 is 75 μm. During the die-cutting process, such as punching and cutting the acetate cloth 2, the die-cutting tool can easily cut through the 25 μm material. The 25 μm thickness of the reinforcing strip 3 makes punching the reinforcing strip 3 smoother, improving the efficiency of the punching process and thus increasing the yield rate of the acetate cloth 2 production. At the same time, the die-cutting tool cannot easily cut through the 75 μm material. The 75 μm thickness of the base film 1 can prevent the die-cutting tool from cutting through the acetate cloth 2 carrier, reduce the collision between the die-cutting tool and the carrier jig, extend the service life of the die-cutting tool, reduce the tool replacement time, and thus improve the production efficiency of die-cutting.

[0027] The experimental principle of the embodiment of the present application is as follows: when laminating the composite tape on the laminating machine, a blue PET release film is used as the base film 1, and the adhesive surface of the acetate cloth 2 is bonded to the base film 1. The base film 1 serves as a carrier for the acetate cloth 2, so that the acetate cloth 2 does not adhere to debris and is easy to move; on the cloth surface of the acetate cloth 2, a reinforcing strip 3 is arranged according to the distribution of the punching positions on the acetate cloth 2, a release film is placed at the first row of punching positions at the starting end of the material starting direction, and a fixed hole film 32 is placed at the other punching positions, and then the reinforcing strip 3 is fixedly bonded to the acetate cloth 2 by a silicone tape 4, thereby improving the hardness of the surface of the acetate cloth 2, making the acetate cloth 2 less likely to deform during the die-cutting process, reducing the occurrence of failures such as lint, uncut fibers, and round hole deformation, and improving the production yield of the acetate cloth 2.

Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention fall within the scope of protection of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
