Automatic cutting device for plastic spiral tube

Abstract

The invention discloses an automatic cutting device for a plastic spiral tube. The device comprises a rack, a supporting traction module and a cutting module. The supporting traction module comprises:a guiding limiting unit for guiding a pipe to the cutting module and limiting lateral movement of the pipe; a traction unit, comprising: a traction roller for driving the pipe forward and a tractionpower source; and a clamping unit, comprising a clamping roller and a movable power source disposed on two sides of the pipe and being opposite to the traction roller. The cutting module is a rotary cutting structure. The device can conveniently process an ordinary plastic tube into a spiral tube. The device has characteristics of simple structure, low investment, low energy consumption, high production efficiency and low cost, and has good use and promotion value.

Description

technical field [0001] The invention relates to the field of automatic processing equipment for plastic products, in particular to an automatic cutting device for plastic spiral tubes. Background technique [0002] The plastic spiral tube has two main uses: one is to replace the traditional rubber tube, as a protective cover for wires and cables, it has the functions of wear resistance, anti-static, anti-ultraviolet, etc. It can not only prolong the service life of the internal products, but also improve the aesthetics; The second is used as a resin introduction tube in the vacuum infusion process of the fiber-reinforced resin-based composite material industry. At present, most plastic spiral pipes are made by hot spiral shaping extrusion process. The equipment used includes extruder, sheath winding machine and high temperature shaping furnace. The process is generally to melt and extrude plastic particles into thin sheet The strip is then wound onto the mandrel, and after ...

Problems solved by technology

[0006] However, the above-mentioned cutting mechanism needs to rotate the pipe, and when the length of the pipe is large, it needs to arrange the pressing mechanism in multiple sections continuously, otherwise the cutting error will be large, and the structure of the pressing mechanism of each section is more complicated, and the manufacturing cost is higher.
