Description

Paper core with high ecological friendly pressure resistance

Technical Field

The utility model relates to the field of novel paper cores with high pressure resistance, in particular to an ecological friendly paper core with high pressure resistance.

Background

The paper core is also a paper cylinder, and the paper core has wide application, such as a painting cylinder, a roll paper framework, a packaging cylinder and other products;

In the existing paper core, the structure is single, the compression resistance is low, and the high-pressure use cannot be met, for example, a composite paper tube disclosed in patent application number CN202221500971.9 is formed by a sealing layer, a first paper layer and an external paper layer which are sequentially covered outside the sealing layer, the sealing layer is formed by spirally winding a sealing film, and the side walls of the sealing film are mutually pressed into a whole to form a pressing part;

In the above patent, the paper core tube adopts multilayer compounding, but the paper core structure is a multilayer round structure, and when the outside pressure is large, the local compressive resistance is small, and the paper core tube is easy to dent.

Disclosure of utility model

Aiming at the problems in the prior art, the utility model aims to provide the paper core with high ecological friendly pressure resistance, the folding paper cylinder can be supported on the outer layer through the multi-layer framework structure, the bending paper plate can be supported on the inner layer, and when the external pressure is high, the two-layer framework structure can play a role in supporting the pressure in a large range, so that the pressure resistance of the whole paper core is improved.

In order to solve the problems, the utility model adopts the following technical scheme.

The utility model provides a paper core that ecological friendly compressive capacity is strong, includes first fiber container, the external surface of first fiber container is fixed with folding fiber container, folding fiber container external surface is fixed with the second fiber container, the inner surface of first fiber container is fixed with crooked cardboard, through multilayer skeleton texture, folding fiber container can support in the skin, crooked cardboard can support in the inlayer, when external pressure is big, two-layer skeleton texture can play the supporting pressure effect in a large scale, improves the compressive resistance of whole fiber core.

Further, the outer end of the folding paper cylinder is provided with a triangular corner joint which is propped against the outer surface of the second paper cylinder.

Further, the curved paperboards are uniformly distributed on the inner side surface of the first paper cylinder.

Further, the end surfaces of the bending paperboards are mutually extruded to support the first paper cylinder outwards.

Further, the second paper cylinder is made of corrugated paper and is processed by roll paper.

Further, the first paper cylinder, the folding paper cylinder, the second paper cylinder and the bending paper plate are bonded by adopting a polyvinyl acetate adhesive.

Further, the thickness of the second paper tube is two millimeters, and the thickness of the first paper tube is one millimeter.

Compared with the prior art, the utility model has the advantages that:

(1) Through multilayer skeleton texture, folding fiber container can support at the skin, and crooked cardboard can support at the inlayer, and when external pressure was big, two-layer skeleton texture can play the effect of supporting pressure in a large scale, improves the compressive resistance of whole refill.
