Description

Technical Field

[0001] The present invention relates to the technical field of product die-cutting, specifically to the die-cutting processing technology for L-shaped products. Background Art

[0002] In mobile phone accessory die-cut parts, L-shaped products often appear, such as battery cover dispensing mylar, anti-stamping mylar and other products. Such L-shaped products are often discharged in an upright manner in the roll material drawing; however, this processing method results in low material utilization rate, and thus high product processing cost. Therefore, there is an urgent need to find a processing technology that can improve the material utilization rate and reduce the product processing cost. Summary of the Invention

[0003] In view of the above problems, the present invention provides a die-cutting processing technology for L-shaped products, which enables two L-shaped products to be processed and formed in a unit area, improving the material utilization rate and reducing the product processing cost.

[0004] The die-cutting processing technology for L-shaped products is characterized in that: the material is processed and formed into two groups of buckled L-shaped products in a unit area through the form of high and low knives, and then the two groups of L-shaped products are independently output from the production line through different bottom films, and then the two bottom films are independently wound up for subsequent operations.

[0005] It is further characterized in that:

[0006] The material is sequentially provided with a material composite layer, an upper bottom film, and a lower bottom film from top to bottom, and the die mold is provided with a high knife and a low knife; the high knife is specifically a die mold that punches downward through the material composite layer and the upper bottom film, and the low knife is specifically a die mold that punches downward through the material composite layer. The formed L-shaped product corresponding to the high knife flows out from the relatively lower part of the production line through the lower bottom film, and the formed L-shaped product corresponding to the low knife flows out from the relatively upper part of the production line through the upper bottom film;

[0007] When the tool bodies corresponding to the high knife and the low knife are different tool bodies, the high knife and the low knife are sequentially arranged along the advancing direction of the material, and the spacing distance therebetween is one step distance;

[0008] When the tool bodies corresponding to the high knife and the low knife are the same tool body, the corresponding cutting edges are downwardly convex cutting edges in a buckled form, and the downward convex cutting edge of the high knife is relatively lower than that of the low knife;

[0009] The cutting edges of the high knife and the low knife corresponding to the short sides of the L-shaped product are respectively arranged on both sides of the width direction of the material composite layer and are arranged facing each other. The cutting edges of the high knife and the low knife corresponding to the long sides of the L-shaped product are respectively arranged at the sequential positions along the material belt direction of the material composite layer, and there is a waste area in the middle. There is a spacing distance between the end of the long side of each L-shaped product and the inner end of the short side of the buckled L-shaped product, and the spacing distance ensures the waste discharging operation;

[0010] The material composite layer is successively provided with a release film, a double-sided adhesive layer, a mylar layer, a marla tape layer, and a protective film from top to bottom.

[0011] When the exposed end of the short side of the L-shaped product has a sharp corner and there cannot be a convex point structure, the cutting edges of the high knife and the low knife extend outward corresponding to the short side of the L-shaped product, and the cut area is larger than the corresponding boundary position of the short side of the L-shaped product.

[0012] A boundary punching die is arranged behind the high knife and the low knife on the production line. The cutting edge of the boundary punching die is arranged corresponding to the short side edges of two L-shaped products, so that the shape of the exposed end of the short side of the L-shaped product meets the design requirements.

[0013] Before the L-shaped product is separated from the production line through the bottom film, the waste materials cut out are discharged.

[0014] The upper bottom film and the lower bottom film are the same bottom film.

[0015] After adopting the present invention, the L-shaped products are arranged in a butting layout corresponding to the width space of the material, so that two L-shaped products can be processed in a unit area, improving the material utilization rate and reducing the processing cost of the products.

[0017] Figure 2 It is a schematic diagram of the punching of the die corresponding to this process;

[0018] Figure 3 It is a schematic diagram of the L-shaped product formed by the processing of the present invention. Detailed Embodiments

[0019] The die-cutting processing technology of the L-shaped product: The material is processed into two groups of butting L-shaped products in a unit area through the form of high and low knives, and then the two groups of L-shaped products are independently output from the production line through different bottom films, and then the two bottom films are independently wound up for subsequent operations.

[0020] During specific implementation, see Figures 1 - 3, from top to bottom, the material is sequentially provided with a material composite layer, an upper base film 6, and a lower base film 7. The material composite layer is sequentially provided with a release film 1, a double-sided adhesive layer 2, a mylar layer 3, a mylar tape layer 4, and a protective film 5 from top to bottom. Among them, the thickness of the release film 1 is 0.03 mm, the thickness of the double-sided adhesive layer 2 is 0.1 mm, the thickness of the mylar layer 3 is 0.05 mm, the thickness of the mylar tape layer 4 is 0.06 mm, the thickness of the protective film 5 is 0.075 mm, and the upper base film 6 and the lower base film 7 have the same thickness of 0.044 mm;

[0021] The die cutter is provided with a high knife 10 and a low knife 20. The high knife 10 is specifically a die cutter that punches downward through the material composite layer and the upper base film 6. The low knife is specifically a die cutter that punches downward through to the protective film 5. The formed L-shaped product corresponding to the high knife 10 flows out from the relatively lower part of the production line through the lower base film 7, and the formed L-shaped product corresponding to the low knife 20 flows out from the relatively upper part of the production line through the upper base film 6;

[0022] The knife bodies corresponding to the high knife 10 and the low knife 20 are the same knife body, and the corresponding cutting edges are downward convex cutting edges in a butting form. The cutting edge of the high knife 10 is relatively lower than the cutting edge of the low knife 20;

[0023] The cutting edges corresponding to the high knife 10 and the low knife 20 of the butted L-shaped product 100 are arranged as follows: The cutting edges of the high knife 10 and the low knife 20 corresponding to the short side 101 of the L-shaped product 100 are respectively arranged on both sides of the width direction of the material composite layer and are arranged facing each other. The cutting edges of the high knife 10 and the low knife 20 corresponding to the long side 102 of the L-shaped product 100 are respectively arranged at sequential positions along the tape direction of the material composite layer, and there is a waste area 103 in the middle. There is a gap distance between the end of the long side 102 of each L-shaped product 100 and the inner end of the short side 101 of the butted L-shaped product 100. The gap distance ensures the waste discharging operation.

[0024] During specific implementation, when the exposed end shape of the short side 101 of the L-shaped product 100 is a sharp angle and there cannot be a convex point structure, the cutting edges of the high knife 10 and the low knife 20 extend outward corresponding to the short side of the L-shaped product 100, and the formed surface area is larger than the corresponding boundary position of the short side of the L-shaped product 100;

[0025] At the back of the production line corresponding to the high knife 10 and the low knife 20, a boundary punching die 30 is provided. The cutting edge of the boundary punching die 30 is arranged corresponding to the edges of the short sides 101 of the two L-shaped products 100, so that the exposed end shape of the short side 101 of the L-shaped product 100 meets the design requirements;

[0026] Before the L-shaped product 100 is separated from the production line through the base film, the cut waste is discharged.

[0027] The principle is as follows: The L-shaped products are arranged in a butting layout corresponding to the width space of the material, so that two L-shaped products can be processed in a unit area, improving the material utilization rate and reducing the processing cost of the products.
