Description

Foam rubber sheet

Technical Field

The utility model relates to a foam rubber sheet.

Background

The foam rubber sheet is made by using EVA or PE foam as a base material, coating solvent type (or hot melt type) pressure-sensitive adhesive on one surface or two surfaces of the base material and then compounding release paper.

Before the foam rubber sheet is adhered, the release paper needs to be completely removed at one time, and then the foam rubber sheet is adhered to the corresponding part of the product, or the corresponding part of the product is adhered to the foam rubber sheet. The technical problem with this type of operation is that: when the release paper is completely torn off, an operator brings the foam rubber sheet close to and partially contacts with the corresponding part of the product, the foam rubber sheet is partially adhered to the corresponding part of the product, the corresponding part of the foam rubber sheet is not completely aligned with the corresponding part of the product, and the foam rubber sheet needs to be adjusted; if the foam rubber sheet is torn off from the product and then pasted again, the viscosity of the foam rubber sheet is influenced, and the combination of the foam rubber sheet and the product is not firm.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: how to design the foam rubber sheet to give an operator an opportunity to adjust the relative position of the foam rubber sheet and a product before the foam rubber sheet is completely attached to the product.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a bubble cotton film, includes the bubble cotton, set up at the viscose layer on bubble cotton surface, attached to from type paper on the viscose layer, bubble cotton film is a mouthful font, and the type paper that leaves of mouth font includes fine rule, small area from type part and large tracts of land from type part, and small area is from type part and large tracts of land from type part and is split by first tearing the trace and form, the fine rule sets up on large tracts of land is from type part, and the fine rule is outstanding the large tracts of land from type part.

According to above-mentioned technical scheme, the operator tears at first to pull the small size from the type part, makes the small size break away from the type part and breaks away from the foam rubber piece, and breaks away from the type part with the large tracts of land because of the existence of first tearing the trace. Afterwards, the foam rubber sheet is close to the position of the product to be adhered, an operator can adhere the adhesive layer exposed on the small-area release part with the product, and the large-area release part which is not torn off can be contacted with the product. Because the small area that adheres with the product is from the viscose layer area of type part is little, consequently, the operator discovers the position that needs to adjust the bubble cotton film, can adjust. After the foam rubber sheet is aligned with the corresponding position of a product, an operator presses one finger to press the original small area from the upper side of the type part, the other finger pulls the protruded large area from the thin line of the type part, the thin line is pulled, the large area from the type part is separated from the foam rubber sheet along with the large area, the viscose layer of the foam rubber sheet is completely exposed, and the operator presses the whole foam rubber sheet again, so that the foam rubber sheet is accurately and firmly combined with the product.

Drawings

The invention will be further explained with reference to the drawings:

FIG. 1 is a schematic view of a foam film;

fig. 2 is a schematic diagram of the release paper after the small-area release part is torn off.

The symbols in the drawings illustrate that:

10. soaking cotton;

20. release paper; 21. a thin wire; 22. a small-area release part; 23. a large-area release part; 24. a first tear score; 25. second tear marks.

Detailed Description

Referring to fig. 1, the foam film comprises foam 10, an adhesive layer disposed on the surface of the foam, and release paper 20 attached to the adhesive layer.

The foam rubber sheet is in a shape of a square, and correspondingly, the adhesive layer and the release paper 20 are in a shape of a square.

Like figure 1, the type paper 20 of mouth font includes that fine rule 21, small area leave type part 22 and large tracts of land from type part 23, and small area leaves type part and large tracts of land and draws trace 24 to cut apart by first tearing to form from type part, the fine rule setting is on large tracts of land is left type part, and the fine rule is outstanding large tracts of land and is left type part, and convenient to use person obtains the fine rule.

The number of the first tearing marks 24 is two, the two first tearing marks are parallel, and the small-area release part 22 is positioned between the two first tearing marks.

The connection between the thin line 21 and the large-area release part 23 may be any one of the methods in the prior art, for example, the thin line is flat and adhered to the large-area release part 23 by glue, or the release paper 20 has a double-layer structure, and the thin line 21 is clamped in the interlayer of the large-area release part 23 when the release paper is produced.

The head end of the thin line 21 starts from the head end of the large-area release part 23, the tail end of the thin line ends at the tail end of the large-area release part, and the thin line is located at the outer edge of the large-area release part. So design, be convenient for reveal the large tracts of land from type part 23 from the foam rubber piece through pulling the fine rule.

A second tear mark 25 is provided at a corner of the large-area release part 23. In operation, as shown in fig. 2, the operator first tears the small-area release portion 22. And then, the foam rubber sheet is close to the position of the product to be adhered, and an operator adheres the adhesive layer exposed at the small-area release part with the product or enables the un-torn large-area release part to be in contact with the product. The operator adjusts the position of the foam rubber sheet to align the foam rubber sheet with the corresponding position of the product. Then, the operator presses the top of the foam rubber sheet with one finger, the pressing position is located right above the original small-area release part 22, and the other finger pulls the thread 21, so that the large-area release part 23 is separated from the foam rubber sheet along with the small-area release part. In the process of pulling the thin line 21, at four corners of the large-area release part 23, corresponding four second tearing pull marks 25 are torn, the large-area release part 23 is divided into five parts, the five parts are connected in series by the thin line at the outer edge of the large-area release part 23, and the thin line is pulled to completely tear off the large-area release part 23 just because the thin line is connected in series with the five parts. The design of the second tear mark 25 enables the operator to smoothly tear off the five parts of the large-area release part 23 one by one through the thin line 21. Then, the operator presses the whole foam rubber sheet, and the foam rubber sheet is accurately and firmly combined with the product.

As an option, the two sides of the foam rubber sheet are provided with adhesive layers, and each adhesive layer is provided with the release paper 20.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
