Automatic PE plastic cast film slitting machine and technology

Abstract

The invention provides an automatic PE plastic cast film slitting machine and technology. A base, an installing frame, an unreeling shaft, a tensioning mechanism, a slitting mechanism, a winding mechanism and a drive mechanism are included. The automatic PE plastic cast film slitting machine is provided, and the following problems that a, when a cast film slitting machine is adopted for slitting acast film, an unreeling shaft and a reeling shaft rotate at the same time under the action of a motor, the cast film is likely to wrinkle and roll when not slit, consequently, uneven cutting or inclination can happen after cast film slitting, and the slitting effect is influenced; and b, according to cast films with different required sizes, different cutter devices commonly need to be replaced for the existing slitting machine, accordingly, the needed-specification cast film is adjusted, consequently, slitting devices different in specification need to be manufactured, cost is high, and efficiency is low, wherein the problems exist in the PE plastic cast film slitting process.

Description

technical field [0001] The invention relates to the technical field of PE plastic cast film production, in particular to an automatic PE plastic cast film slitting machine and a slitting process. Background technique [0002] Cast film is a kind of non-stretched and non-directional flat extrusion film produced by melt casting and quenching. There are two ways of single-layer casting and multi-layer co-extrusion casting. The speed is fast, the output is high, the transparency, gloss, and thickness uniformity of the film are excellent, and the cast film has excellent heat sealing performance and excellent transparency. It is one of the main packaging composite substrates and is used for production High-temperature cooking film, vacuum aluminized film, etc., the market is extremely optimistic. [0003] At present, the following problems exist in the slitting process of PE plastic cast film: a. When using a cast film slitter to cut the cast film, the unwinding shaft and the rew...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an automatic slitting machine for PE plastic cast film, which can solve the following problems in the slitting process of PE plastic cast film: a. When using the cast film slitting machine to cut the cast film, The unwinding shaft and the winding shaft rotate simultaneously under the action of the motor, and the cast film is prone to wrinkles and film shrinkage when it is not slit, so that the cast film will be cut unevenly or skewed after slitting, which will affect the slitting effect; b .According to the cast film of different requirements, the existing slitting machine generally needs to replace different cutter devices to adjust the required specifications of the cast film. This often requires the manufacture of different specifications of the slitting device, and its cost high, low efficiency
