PTFE tape numerical control film drawing machine

Abstract

The invention discloses a PTFE tape numerical control film drawing machine which comprises a film drawing machine body; the film drawing machine body comprises an unwinding device, a heating and stretching device, a high-temperature shaping device, a thickness measuring device and a winding device; a locating shaft is arranged on one side of the heating and stretching device; two layers of rollingshafts are arranged in the high-temperature shaping device, and are connected through a tape; a second motor is arranged at the upper end of the high-temperature shaping device; a second driving shaft is arranged at the lower end of the second motor; a first fan is arranged at the lower end of the second driving shaft; a double-head motor is arranged at the lower end of the inner wall of the high-temperature shaping device; second fans are arranged at the two ends of the double-head motor; and a plurality of heat dissipation holes are formed in the high-temperature shaping device. By using the closed type high-temperature shaping device, the heating time of the tape is lengthened, and the problems that the production efficiency is low and the production quality is poor due to the fact that the continuous heating efficiency on a PTFE tape is low when a common tape drawing machine machines the PTFE tape are solved.

Description

technical field [0001] The invention relates to a film stretching machine, in particular to a PTFE raw material belt digitally controlled film stretching machine, which belongs to the technical field of stretching machines. Background technique [0002] With the development of various social affairs and undertakings, in response to the country's spirit of encouraging independent innovation of small and medium-sized enterprises, there are many shortcomings in the existing slitting equipment that can produce PTFE raw material tapes. The existing raw material tape stretching machines are long-distance Segmented equipment, the grease distance is short, resulting in insufficient time for degreasing, which seriously affects product quality; the shaping part is only 1 meter long, the belt setting time is not enough, the shrinkage rate of the belt is 5% to 10%, and the belt is deformed due to shrinkage. Loss; Segmented independent heating consumes a lot of energy; the raw material b...

[0002] With the development of various social affairs and undertakings, in response to the country's spirit of encouraging independent innovation of small and medium-sized enterprises, there are many shortcomings in the existing slitting equipment that can produce PTFE raw material tapes. The existing raw material tape stretching machines are long-distance Segmented equipment, the grease distance is short, resulting in insufficient time for degreasing, which seriously affects product quality; the shaping part is only 1 meter long, the belt setting time is not enough, the shrinkage rate of the belt is 5% to 10%, and the belt is deformed due to shrinkage. Loss; Segmented independent heating consumes a lot of energy; the raw material belt is stretched for a long distance in one step, it is easy to break the belt, resulting in large loss, and the width and thickness of the stretched product are uneven; and the number of stretched belts is small, and the production low efficiency

[0003] Due to the high temperature resistance of the raw material belt, the general raw material belt stretching machine needs to continuously heat the PTFE raw material belt when processing the PTFE raw material belt, which leads to low production efficiency and low production efficiency. The quality is poor, and there will be wire drawing between the traditional single-axis split raw material belts during the winding process, which will affect the quality of the product
