Description

Technical Field

[0001] The invention belongs to the field of die-cutting technology, and in particular relates to a die-cutting device for narrow double-sided adhesive products and a use method thereof. Background Art

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, and then elastomeric pressure-sensitive adhesive or resin-based pressure-sensitive adhesive is evenly coated on the above base material. It is composed of three parts: base material, adhesive, and release paper (film). Die-cutting is to form customized parts of different sizes of materials through precision processing and cutting according to the predetermined shape. When die-cutting double-sided tape products within a width of 1-3MM, there will be displacement and the waste will take away the product.

[0003] The product shifts during the manufacturing process. The reason for the shift is that the product is too narrow and there is no support on the carrier film. The reason why the waste takes the product away during waste discharge is that the double-sided adhesive layers stick to each other after the material is processed, or the pulling force of the waste due to the small product discharge is greater than the supporting force of the product on the carrier film, causing the product to be taken away by the waste.

[0004] Existing technology is used when discharging waste. Figure 6 As shown, after the material is punched, the double-sided adhesive layers stick to each other, and some products are easily taken away when the waste is discharged. Summary of the invention

[0012] A second upper mold, comprising a second upper mold body and a second cutting line provided on the second upper mold body; and

[0013] A second lower mold, which is used to fix the material to allow the second upper mold to perform punching;

[0014] Wherein, after the first knife line is punched, the first waste discharge component removes the waste, and after the second knife line is punched, the second waste discharge component removes the waste, so as to obtain a narrower double-sided adhesive product.

[0015] Furthermore, the first knife line includes:

[0016] The first section is in the shape of a straight line section and protrudes from the first upper mold body;

[0017] A second section, which is vertically connected to one end of the first section and protrudes from the first upper mold body;

[0018] A third section, which is vertically connected to one end of the first section and protrudes from the first upper mold body; and

[0019] The fourth section has two parts, and the fourth sections are respectively located at both ends of the second section and the third section to separate two adjacent products and protrude from the first upper mold body;

[0020] The second knife line is in the shape of a straight line segment and protrudes from the second upper mold body;

[0021] The first section has the same length as the second knife line, and the first section,

[0022] The lengths of the second section, the third section, and the fourth section protruding from the first upper mold body are the same and equal to the length of the second knife line protruding from the second upper mold body;

[0023] The position of the second knife line punching is between the second section and the third section and is parallel to the first section.

[0024] Furthermore, the first die-cutting assembly also includes a first punching machine, and the first upper mold and the first lower mold are installed on the first punching machine.

[0025] Furthermore, the second die-cutting assembly also includes a second punching machine, and the second upper mold and the second lower mold are installed on the second punching machine.

[0026] Furthermore, the feed assembly includes a material feed roller and a material feed roller drive motor drivingly connected to the material feed roller, and the material fed by the feed assembly is a "cover film-double-sided adhesive-carrier film" that is adhered to each other.

[0027] Furthermore, the first waste discharge assembly includes a first waste row roller and a first waste row roller driving motor drivingly connected to the first waste row roller.

[0028] Furthermore, the second waste discharge assembly includes a second waste row roller and a second waste row roller driving motor drivingly connected to the second waste row roller.

[0029] Furthermore, the flattening and winding assembly includes a finished product winding roller and a finished product winding drive motor connected to the finished product winding transmission, which is used to roll up the narrower double-sided adhesive product after the second knife line is punched.

[0031] The present invention also provides a method for using a die-cutting device for narrow double-sided adhesive products, which is implemented by using the above-mentioned die-cutting device for narrow double-sided adhesive products. The method for using is as follows:

[0032] S1: the feeding assembly delivers a material of the "cover film-double-sided adhesive tape-carrier film" structure, and the first cutting line punches the material to obtain a preliminary punched product;

[0033] S2: material jump distance, the first waste discharge component discharges the waste material after the first knife line punching;

[0034] S3: the material jump distance, the second knife line punches the preliminary punched product, the material jump distance, the second waste discharge component discharges the material waste after the second knife line punching, and obtains a narrower double-sided adhesive product;

[0035] S4: the flattening and winding component performs finished product winding processing on the narrow double-sided adhesive product obtained in S3, and the process is completed.

[0036] The working principle of the present invention is as follows:

[0037] It should be noted that the present application sets up two punching machines, and the punching method of the original single punching machine is performed on the two punching machines. At this time, the combination of the first knife line and the second knife line is the knife line on the original punching machine.

[0038] It should be noted that the first knife line performs the first punching of the material and does not punch out a formed product. Therefore, when the first row of waste components is discharged, a relatively large part of the waste is removed, and the part of the material that has not been punched out will not stick to it. Then the second knife line continues to punch out a complete product. Since the product is obtained after the second knife line is punched out, only the end of the material that has not been punched out away from the product will be discharged during the waste discharge. When the punching is completed at one time, there will not be waste on both sides of the product, which is easy to stick to and take away the product.

[0039] It should be noted that the fourth section is the distance between two adjacent products, and the length is adjusted according to the actual required products.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) This application changes the original one-time punching and forming product into two-time punching and forming, and the product area is discharged twice to avoid the risk of the glue area of ​​the product area being carried away by the waste area.

[0042] (2) The present application has a simple structure and can be completed by simply adding a punching machine to the original production line, and has strong applicability.

[0043] (3) This application saves material usage and improves the yield rate. BRIEF DESCRIPTION OF THE DRAWINGS
