Adhesive tape pasting device

Abstract

The invention provides an adhesive tape pasting device. The adhesive tape pasting device comprises an adhesive tape pulling roller and a vacuum communication mechanism. The outer contour of the adhesive tape pulling roller is a column. A plurality of adhesive tape carrying faces are arranged on the radial outer surface of the adhesive tape pulling roller. Each adhesive tape carrying face is provided with a plurality of holes. An adhesive tape can be sucked on the adhesive tape carrying faces of the adhesive tape pulling roller. A first end face is arranged at one axial end of the adhesive tapepulling roller and is provided with a plurality of air holes. The holes formed in each adhesive tape carrying face correspondingly communicate with one air hole. The vacuum communication mechanism isprovided with a second end face. The second end face is provided with a first matched connection opening and a second matched connection opening. Axial force is applied to correspondingly paste the second end face on the first end face. The adhesive tape pulling roller can rotate relative to the vacuum communication mechanism, so that the first matched connection opening communicates with part ofthe air holes, and the second matched connection opening communicates with the rest of the air holes. By adoption of the adhesive tape pasting device, the control accuracy of the size of the adhesivetape can be improved, the adhesive tape pasting efficiency is improved; and adhesive tape pasting device is simple in structure, reliable in motion and convenient to operate and maintain.

Description

technical field [0001] The invention relates to a processing equipment for roll materials, in particular to a gluing device. Background technique [0002] see figure 1 , an existing gluing device 10a, which is used for affixing a single adhesive paper 50a to a substrate 20a. In the existing gluing method, the conveying direction of the adhesive tape 500a (pointed by the arrow M50a in the figure) is perpendicular to the moving direction of the substrate 20a (pointed by the arrow M20a in the figure). Specifically, a single glued paper 50a is a rectangle with a set length L and width W. In this adhesive tape conveying direction 50a perpendicular to the substrate 20a, the length L of a single adhesive tape 50a is determined by cutting the adhesive tape 500a at an appropriate position by adjusting the tape pulling mechanism. Since the gumming mechanism adopts a reciprocating motion to pull glue, there are problems such as glue pulling, slow glue preparation, many mechanism par...

AI Technical Summary

Problems solved by technology

Since the gumming mechanism adopts a reciprocating motion to pull glue, there are problems such as glue pulling, slow glue preparation, many mechanism parts, and relatively complicated structure; in addition, because the adjustment of the length L of a single gummed paper 50a is by adjusting the cylinder stroke and scale display, there are problems such as insufficient precision, cumbersome actions, and long time consumption
