Abstract

The invention belongs to the field of machinery, and relates to tunnel self-adhesive type waterproof plate/waterproof and drainage plate adhesive tape production equipment, which comprises an extrusion device used for melting and plasticizing to form a continuous body and a forming device used for making the continuous body into a tape material; the downstream end of the forming device is sequentially provided with an edge cutting device used for trimming the edge of the tape material, a point broken line machining device used for manufacturing point broken lines on the tape material in the width direction and a slitting device used for slitting the tape material into a plurality of tapes in the width direction; the forming device comprises a rack; a first forming roller and a second forming roller are arranged on the rack and are arranged in parallel; a plurality of first hook-shaped grooves are arranged on the surface of the first forming roller; a plurality of second hook-shaped grooves are formed in the surface of the second forming roller; and a first press fit gap is formed between the first forming roller and the second forming roller. Hook-shaped structures can be machinedon the two faces of the adhesive tape, the requirement for manufacturing of the integrally-formed adhesive tape is met, and the production efficiency is high due to continuous production.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a production equipment of an adhesive tape, in particular to a production equipment of an adhesive tape for a tunnel self-adhesive waterproof board / drainage board. Background technique [0002] Adhesive tape is a kind of waterproof board, drainage board or anti-drainage board used in the tunnel, with a surface hook structure. The traditional adhesive tape is woven from nylon, and then looped on the surface, the process is relatively complicated. The Chinese invention patent with the publication number CN210087351U discloses an adhesive tape for tunnel self-adhesive drainage board, including a base layer, a plane of the base layer is provided with a hook surface, and the hook surface includes several densely arranged on the base layer. A plastic shaping hook, the plastic shaping hook is umbrella-shaped, and is provided with several hook parts, and the hook parts are arc-shaped and bend tow...
