Description

Technical Field

[0001] The utility model relates to the technical field of paper cores, in particular to a paper core for drawing paper in a business center. Background Art

[0002] The tissue paper used in business centers usually refers to paper towel products placed in public places such as office environments, conference rooms, hotel lobbies, etc. for people to easily take out to wipe their hands or faces.

[0003] During the production process, toilet paper rolls are often wrapped around the outside of a paper core, which is used to support the shape of the roll. When consumers use toilet paper rolls, most of them pull them out from the center of the roll, but the premise of this method of pulling out the paper is to remove the paper core of the roll.

[0004] The paper core in the prior art has the following problems: it is inconvenient to extract the paper core from the paper roll, and the paper core can only be removed violently, resulting in damage to the paper roll. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a paper core for withdrawing paper in a business center, which has a simple structure and can be quickly taken out without damaging the roll of paper.

[0006] The utility model discloses a paper core for paper pulling in a business center, comprising a paper core body; the paper core body is composed of an inner layer of paper, a middle layer of paper and an outer layer of paper;

[0007] The inner paper is spirally wound around several circles to form a cylinder, and the inner paper of adjacent circles is overlapped;

[0008] The middle layer of paper is spirally wound on the outside of the inner layer of paper, and the outer layer of paper is spirally wound on the outside of the middle layer of paper;

[0009] The tensile strength of the middle layer of paper is less than that of the inner layer of paper and the outer layer of paper.

[0010] As a preferred solution of the utility model, the middle layer of paper has the same width as the layer of paper.

[0011] As a preferred solution of the utility model, a tear angle is provided at one end of the cylinder.

[0012] As a preferred solution of the utility model, the inner surface of the middle layer of paper is wrapped around the outer side of the inner layer of paper by adhesive.

[0013] As a preferred solution of the utility model, the inner surface of the outer layer of paper is wrapped around the outer side of the middle layer of paper by adhesive.

[0014] As a preferred solution of the utility model, an indicator mark facing the tearing corner is arranged on the inner wall of the cylinder close to the tearing corner.

[0015] As a preferred solution of the utility model, the overlapping parts of the inner paper layers are pressed together by pressure.

[0016] As a preferred solution of the utility model, the outer layer of paper is white card or gray card, the middle layer of paper is tube paper or thin paper, and the inner layer of paper is white card paper.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the paper core body is composed of three layers of paper, namely, an inner layer of paper, a middle layer of paper and an outer layer of paper; the outer layer of paper is white card or gray card, the middle layer of paper is tube paper or thin paper, and the inner layer of paper is white card; the inner layer of paper is printed with an indication mark toward the tearing angle, which is convenient for determining the tearing direction when extracting; during production, the inner layer of paper is overlapped by 8mm, and the overlapped 8mm is not glued, which is convenient for leaving a tail when extracting, and becomes a tearing angle after sawing; the inner surface of the middle layer of paper is glued and combined with the inner layer of paper, and the inner surface of the outer layer of paper is glued The glue and middle paper are combined and rotated by the paper core shaft with the belt force. The inner layer of 8mm is not glued, and the middle paper and outer paper with glue on the inner surface form the paper core body. Since the tensile strength of the three layers of paper, the inner paper and the middle paper are different, the tensile strength of the inner paper is larger, and the tensile strength of the middle paper is lower, the outer paper is attached to the middle paper with the same width. When extracting, the tearing angle is pulled to drive the bottom paper to tear the middle paper, so that the bottom paper and the outer paper are separated, broken and pulled out, thereby realizing the tearing and extraction of the paper core, and the operation is successful.

[0028] The inner paper 1 is spirally wound around several circles to form a cylinder, and the inner paper 1 of adjacent circles is overlapped;

[0029] The middle layer of paper 2 is spirally wound around the outer side of the inner layer of paper 1, and the outer layer of paper 3 is spirally wound around the outer side of the middle layer of paper 2;

[0030] The tensile strength of the middle paper 2 is smaller than the tensile strength of the inner paper 1 and the outer paper 3 .

[0036] As a preferred solution of the utility model, the overlapping parts of the inner paper 1 are pressed together by pressure.

[0037] As a preferred solution of the utility model, the outer paper 3 is white card or gray card, the middle paper 2 is tube paper or thin paper, and the inner paper 1 is white card paper.

[0038] In this embodiment, the paper core body is composed of three layers of paper, namely, an inner paper 1, a middle paper 2 and an outer paper 3. The outer paper 3 is white card or gray card, the middle paper 2 is tube paper or thin paper, and the inner paper 1 is white card paper; the inner paper 1 is printed with an indication mark 5 toward the tearing corner 4, so as to facilitate the determination of the tearing direction when extracting. During production, the inner paper 1 is overlapped by 8 mm, and the overlapped 8 mm is not glued, so that the tail is left when extracting, and the tearing corner 4 is formed after sawing. The inner surface of the middle paper 2 is glued and combined with the inner paper 1, and the outer paper 3 is glued and combined with the middle paper 2, and the paper core shaft is rotated by belt force, and the inner layer overlapped 8 mm is not glued, and forms the paper core body with the inner surface glued middle paper 2 and the outer paper 3;
