[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, plastic film, elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive. During the production process of the tape, a roller bonding machine is required to squeeze and fix the anti-adhesive tapes at both ends.

[0003] The patent with application number 202320471544.0 discloses a corrugated paper bonding roller mechanism, including a machine base, a roller is arranged in the machine base, a first rotating shaft is fixedly installed on the roller, the first rotating shaft can be rotatably installed on the machine base, a second rotating shaft can be rotatably installed in the machine base, a plurality of connecting seats distributed in a circumferential array are fixedly installed on the second rotating shaft, and pads are fixedly installed at the ends of the connecting seats, and the pads are located at the lower end of the roller. A triangular pyramid is arranged on one side of the roller, one corner of the triangular pyramid abuts against the roller, and connecting pieces are fixedly installed at both ends of the triangular pyramid, and the ends of the connecting pieces are fixedly connected to the machine base, and also includes a power mechanism, which drives the first rotating shaft and the second rotating shaft to rotate, and can synchronously drive the roller and the pad to rotate, the paperboard is located between the roller and the pad and the paperboard is squeezed, and the surface of the roller is adhered to a colloid, and when the roller rotates, the triangular pyramid abuts against the roller, so that the triangular pyramid can scrape off the colloid on the surface of the roller.

[0004] The roller bonding machine in the above technical solution can only deliver glue from one side, which cannot meet the requirements of preparing mesh double-sided adhesive. At the same time, since the position of the scraper remains constant, the residual amount of glue cannot be adjusted during the rolling process. Therefore, when extruding materials of different thicknesses, the amount of glue on the material is too little or too much, and the rolling bonding effect is poor. Utility Model Content

The air pressure mechanism includes an air pump 3 fixed to the side wall of the mounting frame 1 and an air pipe 5 arranged at both ends of the air pump 3. The two air pipes 5 are fixedly connected to the two ends of the glue coating box 7, and a hollow cavity 19 is provided at both ends of the glue coating box 7.
