Description

Technical Field

[0001] The utility model relates to the field of seal equipment, in particular to a composite rubber character belt. Background Art

[0002] The seal mold is the main component of the seal. In order to save costs and improve production efficiency, the current seal molds generally use composite rubber molds. The rubber mold is easy to make. You only need to fix the rubber on the character belt, and then heat the rubber through the mold. First, vulcanize the rubber so that the rubber forms a shape corresponding to the mold. After cooling, the rubber character belt is completed. Finally, it is cut into the rubber molds to be used. This method is suitable for batch production of rubber molds. In order to increase production capacity, a composite rubber character belt structure that can improve production efficiency is needed. Utility Model Content

[0003] The present invention aims to solve the technical problems mentioned in the above background technology and proposes the following technical solutions:

[0004] A composite rubber character belt comprises a cloth belt, two rubber character belts and two rubber anti-slip layers. The cloth belt is annular in structure. Concave areas are symmetrically provided at both ends of the outer side of the cloth belt. The size of the concave areas corresponds to the size of the rubber character belts. The two cloth belts and rubber character belts are symmetrically placed in the concave areas. The two rubber anti-slip layers are provided on the inner side of the cloth belt. The positions of the rubber anti-slip layers correspond to the positions of the rubber character belts.

[0005] Preferably, the rubber lettering strip is interference fit with the recessed area.

[0006] Preferably, the surface of the rubber anti-slip layer has an uneven structure.

[0007] Preferably, a plurality of through holes are provided in the recessed area.

[0008] Preferably, one side of the rubber anti-slip layer has anti-slip textures.

[0009] The beneficial effects of the utility model are:

[0010] 1. The utility model designs the cloth belt into an annular structure, and prevents the rubber character belt from being in the concave area at the upper and lower ends of the cloth belt. When stamping, two pieces of character belt can be stamped at the same time, thereby improving the efficiency of stamping.

[0011] 2. By providing a rubber anti-skid layer on the inner wall of the rubber character belt, the problem of preventing the rubber character belt from slipping when cutting the rubber character belt can be solved.

[0012] 3. By setting through holes in the recessed area, a metal plate with an uneven surface can be inserted into the middle of the tape during embossing. During the vulcanization process, the rubber in the recessed area will move from the through hole to the metal plate under the action of the mold, and a rubber anti-slip layer will be formed after cooling, which can reduce the use of raw materials and reduce costs.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The connection methods described in the terms "fixed connection" and "fixed arrangement" include but are not limited to "welding", "riveting", "adhesion" and "threaded connection". The terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device.

[0020] The directions or positional relationships indicated by terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0021] Example 1

[0022] Reference Figure 1-2 A composite rubber character belt comprises a cloth belt 1, two rubber character belts 2 and two rubber anti-slip layers 3. The cloth belt 1 is a ring structure. Recessed areas 1-1 are symmetrically arranged at both ends of the outer side of the cloth belt 1. The size of the recessed areas 1-1 corresponds to the size of the rubber character belts 2. The two cloth belts 1 and the rubber character belts 2 are symmetrically placed in the recessed areas 1-1. The two rubber anti-slip layers 3 are arranged on the inner side of the cloth belt 1. The position of the rubber anti-slip layer 3 corresponds to the position of the rubber character belts 2.

[0023] Preferably, the rubber character strip 2 is interference fit with the recessed area 1 - 1 .

[0024] Preferably, the surface of the rubber anti-slip layer 3 has an uneven structure.

[0025] In actual operation, the rubber character tape 2 is placed in the recessed area 1-1 on the cloth tape 1, and then the cloth tape 1 is placed in the double-sided character tape mold to complete the engraving operation on the rubber character tape 2, and finally the rubber anti-slip layer 3 is pasted on the inner side of the cloth tape 1.

[0026] Example 2

[0027] Reference Figure 3-4 A plurality of through holes 4 are provided in the recessed area 1-1, and anti-slip patterns are provided on one side of the rubber anti-slip layer 3.

[0028] In actual operation, the rubber tape 2 is placed in the recessed area 1-1 on the cloth tape 1, and then a copper plate with an uneven surface is inserted into the middle of the cloth tape 1. The cloth tape 1 is then placed in a double-sided tape mold. After the rubber tape 2 is engraved, excess rubber will be squeezed into the inner side of the cloth tape from the through hole 4 and cooled and solidified on the uneven copper plate. When it is taken out of the mold, not only is the rubber tape 2 engraved, but a non-slip pad is naturally formed on the inner side of the cloth tape 1.
