Description

Improved layered winding pipe core

Technical Field

The utility model relates to a membrane class goods technical field specifically is an improvement laminar rolling tube core.

Background

In the circular layer rolling, the tube core and the first layer and the second layer of the material rolling are folded due to the thickness difference, and the fold extends from the tube to cause great loss.

In order to eliminate the gap between the innermost layers of the tubes and to avoid the poor folding caused by the extrusion of the gap during the stacking of the inner layers, a series of methods are applied to reduce the poor material caused by the gap between the tubes, so that an improved layered winding tube core is urgently needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an improvement laminar rolling tube core to the laminar rolling product of proposing in solving above-mentioned background art, for eliminating the pipe core inlayer space, it is bad to lead to the fold because of the space extrusion when avoiding the inlayer storehouse, uses a series of methods, reduces because of the bad problem of the pipe core space aroused material.

In order to achieve the above purpose, the utility model provides a following technical scheme: an improved layer type winding pipe core comprises a pipe core body, wherein the pipe core body is in a hollow cylinder shape, foam is arranged on the outer surface of the pipe core body, and the foam is a compressive material;

the outer surface of the tube core body is provided with an opening groove, and the left and right heights of the inside of the opening groove are different;

the outer surface of the tube core body is provided with a slope, and the left height and the right height of the slope surface are different.

Preferably, the material of the tube core body is PE material.

Preferably, the thickness of the tube core body material is 0.4-16 mm.

Preferably, the foam is closed-cell single-sided foam viscose, and the thickness of the foam is 0.02-0.1 mm.

Preferably, the width of the open groove is 0.005-1 mm, and the depth of the open groove is 0.1-10 mm.

Preferably, the width of the slope is 5-50 mm, and the depth of the slope is 0.001-0.5 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

1. by the tube core body of the three improved technical schemes, each group is rolled for 400 meters, the following results are obtained, the blank tube core differential failure rate is 10%, the foam tube core differential failure rate is 7%, the groove tube core differential failure rate is 5%, the slope tube core differential failure rate is 2%, and the four schemes use the slope tube core differential rate as the lowest, so the slope tube core rolling effect is the best.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

an improved layer type winding pipe core comprises a pipe core body 1, wherein the pipe core body 1 is in a hollow cylinder shape, foam 2 is arranged on the outer surface of the pipe core body 1, and the foam 2 is a compressive material;

an opening groove 3 is formed in the outer surface of the tube core body 1, and the left and right heights of the inside of the opening groove 3 are different;

the outer surface of the tube core body 1 is provided with a slope 4, and the left and right heights of the surface of the slope 4 are different.

Further, the tube core body 1 is made of PE material.

Further, the thickness of the material of the tube core body 1 is 0.4-16 mm.

Furthermore, the foam 2 is made of closed-cell single-sided foam cotton glue, and the thickness is 0.02-0.1 mm.

Furthermore, the width of the open groove 3 is 0.005-1 mm, and the depth of the open groove 3 is 0.1-10 mm.

Further, the width of the slope 4 is 5-50 mm, and the depth of the slope 4 is 0.001-0.5 mm.

The working principle is as follows: one is through directly rolling up the material on the surface of tube core body 1, its two are through pasting the bubble celloidin on tube core body 1 surface, because the bubble cotton has compressibility, make the material fold loss that the segment difference that can eliminate the thickness and cause arouses, it is three through coming in and going out the one end of material in the open groove 3, thereby fix the material, because the inside left and right sides height of recess is different, make the material when the rolling second circle, both can eliminate the offset space, it is four through offering the tube core body 1 surface spraying one deck gluing agent of slope 4, fix the material from this, because the slope is highly different about, consequently when the material rolling is to the second circle, can eliminate the offset space.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
