Splitting machine for slip shaft of double gas circuits

Abstract

The invention belongs to a splitting machine for a slip shaft of double gas circuits. The splitting machine comprises a machine frame composed of a side baffle (1), a side wall board (2) and a main water board (22). The splitting machine is characterized in that a shaft body (9-3) is installed at the left end of a gas inlet mechanism (9-30); a plurality of groups of slip rings (27) are installed at the left side of the shaft body (9-3); a slip ring piston (27-8) is installed inside a cavity of a piston seat (27-6); a sliding block (27-10) provided with an oblique face is installed on the upper portion of the right end face of the slip ring piston (27-8); two super magnets (27-9) are installed on the oblique face of the sliding block (27-10); an expansion piece (27-3) provided with an oblique face is installed under the super magnets (27-9); a pointed spring (27-4) is installed in a groove in the outer face of the expansion piece (27-3). By means of the splitting machine, the tension of a film is controlled by expanding a material pipe and controlling the sliding friction force between the slip rings and the shaft, the slip rings can be connected with one another tightly, and the production efficiency and the splitting 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
