Double air path slip shaft slitting machine

Abstract

The invention belongs to a dual-air path slip shaft slitting machine, which includes a frame composed of side baffles (1), side wall panels (2) and main wall panels (22), and is characterized in that the air intake mechanism ( The left end of 9‑30) is equipped with shaft main body (9‑3), and multiple sets of slip rings (27) are installed on the left side of shaft main body (9‑3); slip ring pistons are installed in the cavity of piston seat (27‑6) (27‑8), the upper right end face of the differential ring piston (27‑8) is equipped with a slider (27‑10) with a slope, and the slope of the slider (27‑10) is equipped with two powerful magnets (27‑10) 9), under the strong magnet (27-9) there is an inclined-plane expansion piece (27-3); in the outer groove of the expansion piece (27-3) a beak spring (27-4) is housed; this invention solves the problem of The material tube is tightened and the tension of the film is controlled by controlling the sliding friction between the slip ring and the shaft, and the problem of tight connection between the slip ring and the ring is solved, and the production efficiency and the cutting quality of the film are improved.

Description

technical field [0001] The invention belongs to a slitting machine, in particular to a dual-air path slip shaft slitting machine. Background technique [0002] At present, film is widely used for packaging products. With the continuous improvement of packaging quality requirements, the requirements for stretching ratio of films are getting smaller and smaller, and the requirements for uniformity of winding end faces are also getting higher and higher. In order to meet the above-mentioned technical requirements, the control ability of winding film tension must be improved. At present, the slip shaft of the slitting machine is controlled by one way of air, which not only needs to control the expansion tube, but also controls the winding tension. In this way, there is a problem of the expansion of the material tube, the winding tension is too large or the winding tension is small. Yes, the tube is not tight anymore. If the tension is controlled by one way of air, the two ring...

AI Technical Summary

Problems solved by technology

If the tension is controlled by one way of air, the two rings of the mechanical expansion tube will not be tightly connected, resulting in a differential movement between the rings, which will affect the uniformity of the end face of the winding film; in addition, the internal felt is easy to Adhered sundries need to be cleaned and replaced frequently, affecting production efficiency and slitting quality
