Description

Technical Field

[0001] The utility model relates to the technical field of coiled material products, in particular to a coiled material product with a tear line. Background Art

[0002] In the die-cutting electronics industry, general products are divided into sheets and coils. Coils can directly roll up the punched products, while sheets need to be cut into individual products by cutting coils. The prior art generally uses a slicer or scissors to cut. The scissors method has low production capacity and may not be cut straight. The slicer method is prone to wrinkles during the slicing process due to static electricity in the product, resulting in a high defect rate and failure to meet usage requirements. Based on the above, we propose a coil product with a tear line. Utility Model Content

[0006] The product comprises butter paper, which is bonded and fixed to the top of the material strip, and a first double-sided adhesive PSA is bonded and fixed to the front side of the top of the butter paper.

[0007] Preferably, a second double-sided adhesive PSA is bonded and fixed to the bottom of the butter paper, and the bottom of the second double-sided adhesive PSA is bonded to the top of the material tape.

[0008] Preferably, the rear side of the butter paper is integrally provided with an outer edge, the top of the outer edge is integrally provided with a first protrusion, the top left of the butter paper is integrally provided with a second protrusion, and the top right of the butter paper is integrally provided with a third protrusion.

[0009] Preferably, a first through hole is formed on the top of the butter paper, and the first through hole is aligned with the corresponding second double-sided adhesive PSA.

[0010] Preferably, the first double-sided adhesive PSA and the second double-sided adhesive PSA are both made of polypropylene and polyethylene materials through a special process.

[0011] Compared with the existing technology, the beneficial effects of the utility model are:

[0012] The utility model can directly tear off products individually by setting multiple tear lines, without the need for personnel to use scissors to cut pieces or slicers to slice pieces, which is convenient for personnel to operate, improves product quality, and can effectively reduce the defective rate of products. The product is connected to the material tape by the second double-sided adhesive PSA, so the product can be quickly peeled off the material tape, further improving the convenience of personnel operation.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1-2 A coiled product with tear lines, comprising a coiled product body, the coiled product body comprising a coil core 4, a material strip 1 is wound around the outer side of the coil core 4, a plurality of tear lines 3 are arranged on the material strip 1 at equal intervals, a same product 2 is arranged between two adjacent tear lines 3, and the product 2 is bonded and fixed to the top of the material strip 1;

[0018] Product 2 includes butter paper 202, which is bonded and fixed to the top of the material strip 1, wherein the bottom of the butter paper 202 is bonded and fixed with a second double-sided adhesive PSA203, the bottom of the second double-sided adhesive PSA203 is bonded to the top of the material strip 1, and the connection between the butter paper 202 and the material strip 1 is achieved through the second double-sided adhesive PSA203, the top of the butter paper 202 is provided with a first through hole 205, the first through hole 205 is aligned with the corresponding second double-sided adhesive PSA203, and the top front side of the butter paper 202 is bonded and fixed with a first double-sided adhesive PSA204, the first double-sided adhesive PSA204 is provided to achieve the connection between the butter paper 202 and the external installation component, wherein the first double-sided adhesive PSA204 and the second double-sided adhesive PSA203 are both made of polypropylene (PP) and polyethylene (PE) materials through a special process;

[0019] An outer edge is integrally provided on the rear side of the butter paper 202, a first protrusion 201 is integrally provided on the top of the outer edge, a second protrusion 207 is integrally provided on the left top of the butter paper 202, and a third protrusion 206 is integrally provided on the right top of the butter paper 202. The arrangement of multiple protrusions makes it convenient for personnel to peel off the butter paper 202; the utility model can directly tear off the product 2 separately by setting multiple tear lines 3, and personnel do not need to use scissors to cut pieces or slicers to slice, which is convenient for personnel to operate, improves product quality, and can effectively reduce the defective rate of product 2. In addition, the product 2 is connected to the material strip 1 by the second double-sided adhesive PSA203, so that the product 2 can be quickly peeled off from the material strip 1, further improving the convenience of personnel operation.

[0020] Working principle: When processing and producing coil products, after the coil product body is formed, multiple tear lines 3 are evenly spaced on the material strip 1 to prevent the material strip 1 from being completely broken, which is convenient for winding, and the product 2 is set between two adjacent tear lines 3. When removing the product 2, it can be directly torn from the middle of the tear line 3 to remove the product 2 individually. This method does not require personnel to use scissors to cut the pieces or slicers to slice them. The direct tearing method is convenient for personnel to operate, improves product quality, and can effectively reduce the defective rate of product 2;

[0021] When the product 2 needs to be removed from the material strip 1, since the butter paper 202 is connected to the material strip 1 through the second double-sided adhesive PSA 203, the butter paper 202 can be pulled upwards through the first protrusion 201, the second protrusion 207 and the third protrusion 206 to peel off the butter paper 202 from the material strip 1, which is convenient for personnel to operate.
