Back-cutting rewinding equipment

Abstract

The invention discloses back-cutting rewinding equipment which comprises a nicking tool, a finished product winding shaft and a waste winding shaft, wherein the nicking tool is used for cutting off back paper along the central symmetric line in the length direction without touching adhesive paper, the finished product winding shaft is used for collecting cut-off back paper and the adhesive paper,and the waste winding shaft is used for collecting transparent films separated from the back paper and the adhesive paper. The finished product winding shaft is composed of a shaft core and a baffle plate at one shaft end, the baffle plate is provided with an annular tapered surface capable of conveniently guiding the back paper and the adhesive paper to enter the finished product winding shaft, and one sides of the back paper and the adhesive paper abut against the baffle plate for rewinding; a blind hole is formed in the center of the baffle plate, the shaft core is inserted into the blind hole to be matched with the blind hole, and the depth of the blind hole is half of the value obtained by subtracting the width of the back paper or the adhesive paper from the axial length of the shaftcore; and the shaft core is provided with an openable limiting rod capable of applying elastic pressure to the shaft core, when the limiting rod is in a closed state, the shaft core and the baffle plate are limited and fixed, and a separating path is provided for the shaft core when the limiting rod is opened and closed. By adopting the back-cutting rewinding equipment, separation and collectionof coiled materials with different layers can be facilitated, and meanwhile, specific coiled materials are cut off, so that the efficiency and the quality of cutting and collecting are guaranteed.

Description

technical field [0001] The invention relates to the field of rewinding and cutting, in particular to a back cutting and rewinding device. Background technique [0002] In the field of rewinding and cutting, there is no mature back-cutting and rewinding equipment on the market. The original paper is divided into three layers, the upper layer-backing paper, the middle layer of gummed paper, and the lower layer of transparent film. A back cutting and rewinding equipment needs to solve the following technical difficulties: 1. It can cut through the back paper of raw paper without damaging the gummed paper. 2. Separate the adhesive paper from the transparent film, rewind the back-cut adhesive paper, and discard the transparent film after rewinding. 3. Rewinding needs to ensure the flatness and tightness and the distance from both ends of the shaft core. 4. The rewinding length needs to be precise, and the setting can be adjusted.
