Description

Double-faced adhesive tape structure for battery

Technical Field

The utility model relates to a gummed paper product technical field especially relates to a two-sided gummed paper structure for battery.

Background

Double-sided adhesive paper is including following from type layer, glue film and going up from the type layer, and traditional double-sided adhesive paper upper and lower from type layer and glue film length the same, in actual production process, need peel off type layer and glue film, because of the length the same from type layer and glue film, difficult with the glue film with from the type layer separation to take place the impaired phenomenon of glue film, not only influence production efficiency, influence the effective usable floor area of glue film moreover, increase use cost.

Disclosure of Invention

In order to overcome the problem that has double faced adhesive tape to leave the difficult separation of type layer and glue film among the prior art, the utility model aims to provide a double faced adhesive tape structure for battery conveniently from the separation of type paper and glue film, improves production efficiency, improves the effective use area of glue film, reduces use cost.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a double-sided adhesive paper structure for a battery comprises a lower release layer, a plurality of adhesive layers and a plurality of upper release layers, wherein the adhesive layers are adhered to the lower release layer, and two adjacent adhesive layers are arranged in parallel at intervals;

one go up from the type layer including last body, go up handle portion, locate the knurling layer of last handle portion and locate the recess of last handle portion, go up the body adhesion in the glue film, go up handle portion with go up body fixed connection, the recess is followed the width direction setting of last handle portion.

Furthermore, the groove is located on the bottom surface of the upper handle portion and is close to the glue layer.

Furthermore, the embossing layer is located the top surface of last handle portion, the embossing layer is kept away from last body setting.

Furthermore, go up body, last handle portion, knurling layer and recess integrated into one piece.

Further, the length of the lower release layer is greater than that of the adhesive layer.

The utility model has the advantages that: through setting up the upper release layer of taking handle portion, conveniently grab and hold the upper release layer, make things convenient for the glue film and lower release layer, go up the separation from the layer, improve production efficiency.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.

Referring to fig. 1 to 3, a double-sided adhesive paper structure for a battery of the present invention includes a lower release layer 1, a plurality of adhesive layers 2 and a plurality of upper release layers 3, wherein the plurality of adhesive layers 2 are adhered to the lower release layer 1, and two adjacent adhesive layers 2 are arranged in parallel and at an interval;

one upper release layer 3 comprises an upper body 31, an upper handle part 32, an embossing layer 33 arranged on the upper handle part 32, and a groove 34 arranged on the upper handle part 32, wherein the upper body 31 is adhered to the adhesive layer 2, the upper handle part 32 is fixedly connected with the upper body 31, and the groove 34 is arranged along the width direction of the upper handle part 32.

Specifically, in this embodiment, the lower release layer 1 is made of a whole piece of release paper, a plurality of adhesive layers 2 are adhered according to a preset number, the width of an upper release layer 3 is the same as the width of one adhesive layer 2, the length of an upper body 31 of the upper release layer 3 is the same as the length of the adhesive layer 2, an upper handle portion 32 is connected to the upper body 31 and extends in a direction away from the upper body 31, a knurling layer 33 is arranged on the upper handle portion 32 for increasing friction force, so as to facilitate grasping of the upper handle portion 32 to avoid slipping, when in use, the grasping of the upper handle portion 32 simultaneously presses down the release layer 1, so that the adhesive layer 2 and the upper body 31 are simultaneously separated from the lower release layer 1, the adhesive layer 2 separated from the lower release layer 1 is adhered to an external workpiece, then the upper handle portion 32 is grasped, so that the upper body 31 is separated from the adhesive layer 2, the separation of the upper release layer 3 and the lower release layer 1 is completed, and the, the upper handle part 32 can be bent, that is, the upper handle part 32 is folded on the top of the upper body 31, so that the storage is convenient.

From type layer 3 on through setting up upper band handle portion 32, conveniently grab and hold and go up from type layer 3, make things convenient for glue film 2 and lower from type layer 1, go up from breaking away from of type layer 3, improve production efficiency.

The groove 34 is located on the bottom surface of the upper handle portion 32 and close to the glue layer 2, and the groove 34 is close to the glue layer 2, so that the upper handle portion 32 can be conveniently bent.

The embossing layer 33 is located the top surface of the upper handle portion 32, the embossing layer 33 is far away from the upper body 31, the embossing layer 33 is of a net structure, friction force is increased, and the upper handle portion 32 is convenient to hold.

Go up body 31, go up handle portion 32, knurling layer 33 and recess 34 integrated into one piece, knurling layer 33 is through embosser suppression and is formed, and recess 34 is through shaping die cutting processing, and processing is simple, facilitates the use.

The length of the lower release layer 1 is greater than that of the glue layer 2, so that the glue layer 2 is protected from being damaged.
