Description

Technical Field

[0001] The utility model relates to the field of adhesive tape processing devices, in particular to an adhesive tape uniform gluing device. Background Art

[0002] Adhesive tape is composed of two parts: base material and adhesive. It connects two or more unconnected objects together by bonding. A layer of adhesive is coated on its surface.

[0003] Existing roll-type tapes generally adopt a matching structure of a pressure roller and a winding roller, such as Chinese patent CN202321057600.2, to achieve uniform coating of glue. However, for sheet tapes, this structure generally uses flat tapes to cut predetermined shapes and then stack them. However, this structure may cause glue to overflow from the sides of the sheet tape. Utility Model Content

[0004] The main purpose of the utility model is to provide a device for uniformly applying glue to a tape, aiming to improve the existing tape coating structure, thereby achieving uniform coating of the adhesive layer and better bonding effect, and at the same time, there will be no glue overflow when the sheet tapes are stacked on each other.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a device for uniformly gluing an adhesive tape, comprising:

[0006] A movable frame, the movable frame comprising a base, a horizontal movable device arranged on the base, and a vertical movable device arranged on the horizontal movable device, the vertical movable device being provided with a positioning seat, and the horizontal movable device and the vertical movable device being capable of driving the positioning seat to move horizontally or vertically;

[0007] The glue applicator is arranged on the positioning seat. The glue applicator includes a main body and a spray hole arranged on the main body. The upper end of the spray hole is connected to the glue supply device, and the lower end of the spray hole is arranged on the lower wall of the positioning seat for supplying glue to be coated on the belt body.

[0008] In the actual design of the technical solution of the utility model, the positioning seat is driven by the moving frame to move the glue applicator. When the sheet moves to the top of the glue applicator, the nozzle sprays a predetermined amount of glue, and then the anti-adhesive film is attached in the next process, thereby realizing the assembly of the sheet tape. The precise gluing of the glue applicator can effectively reduce the problem of glue overflow, and effectively improve the shear force of adhesion of some tapes with higher requirements; at the same time, the existing processing method of controlling the thickness and uniformity of the glue by the pressure roller is changed, and the processing stability is effectively improved;

[0009] The spray holes can also be understood as glue guns arranged at multiple intervals, thereby achieving uniform gluing. BRIEF DESCRIPTION OF THE DRAWINGS
