And the pressing part is extruded into the groove by the convex teeth, so that the pressing part is bent and deformed while being extruded in the groove. The utility model has the advantages that paper fibers in the pressing part can be more easily combined together, so that a plurality of layers of paper in the pressing part can be more firmly combined, and the pressing effect is improved.

Description

Technical Field

[0001] The utility model relates to a paper roll sealing device which fixes the paper tail of a paper roll on the outer peripheral surface of the paper roll in a mechanical pressing manner. Background Art

[0002] The mechanical pressing paper roll sealing device is equipped with a clamping piece for clamping the outer circumference of the paper roll. Two mutually opposing engaging surfaces of the clamping piece are pressed on the outer circumference of the paper roll to form a pressing part that makes several layers of paper combine into one and no longer loose, thereby fixing the paper tail of the paper roll on the outer circumference of the paper roll to complete the paper roll sealing. However, the existing mechanical pressing paper roll sealing device has the problem of poor pressing effect, and the paper is not firmly combined. Utility Model Content

[0003] The utility model aims to provide a mechanical pressing type paper roll sealing device to improve the pressing effect and make several layers of paper in the pressing part more firmly combined into one.

[0004] The utility model is realized as follows: a mechanical pressing paper roll sealing device comprises clamping parts opposite to each other, when the clamping parts are close to each other, a pressing part which makes several layers of paper combined into one and no longer loose is pressed on the outer peripheral surface of the paper roll, in particular, one side of the clamping part is provided with a convex tooth, and the other side of the clamping part is provided with a groove opposite to the convex tooth, when the clamping parts are close to each other, the convex tooth squeezes the pressing part into the groove, so that the pressing part is squeezed in the groove and bends and deforms at the same time.

[0005] The utility model has the advantage that the structure in which the protruding teeth and the grooves on the clamping piece are opposite to each other enables the pressing part of the paper roll to bend and deform while being squeezed in the groove, thereby making it easier for the fibers of the paper to be combined together, making the several layers of paper in the pressing part more firmly combined, and improving the pressing effect.

[0013] To facilitate understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described. The purpose of providing these embodiments is to make the present invention more thoroughly understood.

[0014] See also Figure 1 , Figure 2 The mechanical pressing paper roll sealing device is provided with clamping parts facing each other, wherein the clamping part 1 on one side is provided with a convex tooth 2, and the clamping part 3 on the other side is provided with a groove 4 facing the convex tooth 2. When the clamping parts 1 and 3 are close to each other, as shown in FIG. Figure 3 , Figure 4 As shown, a pressing portion 6 is formed on the outer peripheral surface of the paper roll 5 to combine several layers of paper into one piece and no longer loose. When the clamping parts 1 and 3 are brought closer to each other, the protruding teeth 2 squeeze the pressing portion 6 into the groove 4, so that the pressing portion 6 is squeezed in the groove 4 and bends and deforms, thereby making it easier for the fibers of the paper to be combined together, so that the several layers of paper in the pressing portion 6 are combined more firmly, and the pressing effect is improved.

[0015] The clamping parts can be brought closer to each other by the clamping parts 1 and 3 on both sides moving relative to each other at the same time, or the clamping part on any one side can be fixed and the clamping part on the other side can be brought closer to it.

[0016] Figures 5 to 7 Three different shapes of the protruding teeth 2 and the recessed grooves 4 are listed. Figure 8 and Fig. 9 Furthermore, two exemplary embodiments are shown. Figure 8 The protruding teeth 2 of the embodiment shown are integral along the width direction of the clamping piece. Fig. 9 The protruding teeth 2 of the illustrated embodiment are arranged at intervals along the width direction of the crimping member.

[0017] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of protection of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.

Claims

1. A mechanical pressing paper roll sealing device, comprising clamping parts facing each other, when the clamping parts are close to each other, a pressing part is formed on the outer peripheral surface of the paper roll to combine several layers of paper into one and no longer loose, wherein: One side The clamping piece on one side is provided with a convex tooth, and the clamping piece on the other side is provided with a groove opposite to the convex tooth. When the clamping pieces are close to each other, the convex tooth squeezes the pressing part into the groove, so that the pressing part is squeezed in the groove and bends and deforms.
