Description

Technical Field

[0001] The invention belongs to the technical field of die cutting, and in particular relates to a device for preventing non-rebound of foam with glue on one side and a processing method thereof. Background Art

[0002] Foam is a material made of foamed plastic particles. It is a high molecular polymer with many small pores. The solid phase is a polymer matrix, and the small pores are filled with gas. It has many outstanding properties, such as flame retardancy, wear resistance, heat resistance, cold resistance, cushioning, sound absorption, shockproof, and sealing, such as excellent resistance to compression deformation, ultra-high resilience, impact resistance, and elastic durability. It is widely used in various precision products for shockproof and other purposes.

[0003] Normally, foam needs to be used in conjunction with double-sided tape when in use. Because the double-sided tape is sticky, it can play a fixing role, and the foam is soft and can play a role in shockproof, cushioning or sealing. When the two are used together, the glue will not move after fixing, which can better realize the advantages of the foam.

[0004] Existing technologies such as Figure 1 to Figure 5 As shown, a first material feeding mechanism 1, a double-sided adhesive waste discharge mechanism 2, a foam feeding mechanism 8, a cutting die 4-1, a first contour waste discharge mechanism 5 and a finished product winding mechanism 15 are sequentially arranged along the moving direction of the material belt, and a plurality of rolling and laminating mechanisms 16 are arranged on the material belt;

[0005] When die-cutting the foam glue, the foam at the edge will often not rebound easily and become thinner. This is mainly due to the fact that when die-cutting the foam, Figure 5 As shown, the blade 17 is 30 degrees, and when it is squeezed from the foam surface to the double-sided tape, the edge of the foam will be wrapped to the position of the double-sided tape, causing the two to stick together, resulting in Figure 4 As shown in the figure, the foam can no longer rebound, the product is unqualified and the cost is increased. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a device for preventing non-rebound of foam with glue on one side and a processing method thereof.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0014] Furthermore, the first contour waste discharge mechanism includes a first contour waste discharge roller and a first contour waste discharge roller driving motor drivingly connected to the first contour waste discharge roller, and the first contour waste discharge mechanism is used to discharge waste cut by the first cutting die.

[0015] Furthermore, the sealing tape feeding mechanism includes a sealing tape feeding roller and a sealing tape feeding drive motor transmission-connected to the sealing tape feeding roller. The sealing tape feeding mechanism feeds out the sealing tape, and sequentially adheres to each other from top to bottom to form a composite layer structure of "sealing tape-second auxiliary material release film-double-sided tape-first auxiliary material release film".

[0024] Compared with the prior art, the present invention has the following benefits:

[0025] (1) The first cutting die of the present invention has a smaller size than the product, and the second cutting die has a larger size than the product, so that the glue is shrunk inward and the foam is expanded outward. In this way, when the foam is punched, the glue will not stick to the edge of the foam. After the edge of the foam is squeezed and punched by the cutting die, it will rebound within a certain period of time according to its own characteristics.

[0026] (2) When the present invention is used to produce products, the thickness of the foam can rebound to a suitable size, thereby improving the quality of the product, reducing costs, and increasing productivity. BRIEF DESCRIPTION OF THE DRAWINGS
