[0036] Working principle:

[0037] In the process of actual creation, in order to avoid the following defects existing in the prior art: "the existing technology of adhesive tape coating is mainly the mutual alignment of rolling brush and base material. However, the tensioning force of the surface of the base material is insufficient in this alignment contact mode, which easily leads to the problem of insufficient glue coating and pressing force, and further reduces the adhesive force of the finished adhesive tape." And the tensioning assembly 2 and the rolling brush assembly 3 are specifically proposed;

[0038] Tensioning assembly 2:

[0039] In order to improve the pre-tightening force between the rolling brush and the base material 1, we need to tension the base material 1 during conveying. Therefore, we set a pair of upper tensioning wheels 4 and a pair of lower tensioning wheels 5 at the input end and the output end of the base material 1 respectively. The upper and lower tensioning wheels press each other to tension the base material 1 on both sides while conveying the base material 1. The base material 1 in the tensioning state is easier to add pre-tightening force.

[0040] Rolling brush assembly 3:

[0041] The rolling brush assembly 3 is divided into a material feeding assembly and a brush assembly. We separate the feeding part and the brushing part from each other. The material box 14 is used to pre-store the glue material. Since the glue needs to be released slowly to uniformly act on the surface of the coating wheel 8, and then the uniform coating of the glue can be realized. Therefore, the cotton brush 15 is inserted and installed at the bottom of the material box 14. The glue flowing from the material box 14 is uniformly adsorbed on the surface of the cotton brush 15. Start the motor 12, and the motor 12 controls the rotation of the coating wheel 8 through the main shaft 9, and then the glue on the surface of the cotton brush 15 is uniformly wrapped on the surface of the coating wheel 8.

[0042] The coating wheel 8 and the base material 1 are pre-tensioned to have an extrusion arc between them. The part of brushing glue is located inside the arc. The glue on the surface of the coating wheel 8 can uniformly act on the surface of the base material 1 under the extrusion action, thereby realizing the stable glue adhesion of the base material 1 and avoiding the problem that the glue cannot be stably attached in the prior art.
