Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, an easy-to-roll paper core according to a preferred embodiment of the present invention includes a paper core body, the paper core body is composed of an inner layer paper 1 and an outer layer paper 2, the inner layer paper 1 spirally surrounds a plurality of turns to form a cylinder, specifically, the inner layer paper 1 can spirally surround in a clockwise direction, the outer layer paper 2 is wrapped and adhered at a joint between adjacent turns of the inner layer paper 1, and the outer layer paper 2 extends along a spiral line 3 formed between adjacent turns of the inner layer paper 1 and is wound on the outside of the cylinder to form the paper core body, and a tensile strength of the inner layer paper 1 is greater than a tensile strength of the outer layer paper 2.

When the easy-to-unwind roll paper core provided by the utility model is applied, the inner layer paper 1 and the outer layer paper 2 are rotationally formed through the paper core shaft in a belt pressing mode to form a paper core body, and the inner layer paper 1 is torn, because the surface strength of the inner layer paper 1 is different from that of the outer layer paper 2, the tensile strength of the inner layer paper 1 is high, the tensile strength of the outer layer paper 2 is low, the corner of the inner layer paper 1 is pulled to drive the inner layer paper 1 to tear the outer layer paper 2 during extraction, so that the middle of the outer layer paper 2 along the spiral line 3 is broken, the outer layer paper 1 is conveniently extracted outwards, the paper core body can be extracted in a mode of tearing the outer layer paper 2, and the operation is convenient.

On the basis of the above embodiment, the inner paper sheets 1 of adjacent circles are overlapped, and the overlapped parts are not bonded, so that the paper core body is cut to form the tearing angle 5, it should be noted that, in actual production, the paper core body is long, and needs to be cut into segments according to the length of the roll paper, and then when the paper core body is cut, the overlapped parts between the inner paper sheets 1 naturally generate raised edges, that is, the tearing angle 5.

Specifically, in the present embodiment, the overlapping width between the inner paper 1 of adjacent circles may be set to be 5mm, but the present invention is not limited to this width, and other values are within the protection scope of the present application.

On the basis of above-mentioned embodiment, inlayer paper 1 is the ivory board, and outer ply paper 2 is the sand tube paper, and the stretching resistance intensity of ivory board is greater than the stretching resistance intensity of sand tube paper, just the surface strength of ivory board is greater than the surface strength of sand tube paper, can stretch out the sand tube paper promptly when tearing the ivory board, and the sand tube paper breaks along helix 3 promptly, and because the surface strength of ivory board is greater than the surface strength of sand tube paper, when tearing the ivory board, can drive the top layer of sand tube paper simultaneously and break away from the sand tube paper, more conveniently tears.

In the above embodiment, the inside of the cylinder is provided with a tear indication arrow, and the position of the tear angle 5 is marked by the tear indication arrow to facilitate quick finding.

In the above embodiment, specifically, the outer-layer paper 2 is bonded to the inner-layer paper 1 through glue, and a gap is formed between adjacent circles of the outer-layer paper 2, so that the outer-layer paper 2 of the adjacent circles is prevented from being bonded together due to overflow of the glue and is not easy to tear.

In another embodiment, as shown in fig. 3, the inner side of the outer layer paper 2 and the outer side of the inner layer paper 1 are both covered with a film, and the outer layer paper 2 and the inner layer paper 1 on both sides of the spiral line 3 are respectively pressed with a hot-melt roller line 4 through a hot-melt roller, so that the film on the outer layer paper 2 and the film on the inner layer paper 1 are hot-melt bonded at the roller line 4, when the inner layer paper 1 is torn, the outer layer paper 2 and the inner layer paper 1 can be driven to be separated at the roller line 4, it should be noted that the connection strength of the hot-melt connection between the films is not large, and the films are easy to separate, which is a known technology.

Finally, it should also be noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
