Distance-adjustable fixed-distance point-breaking type cutting device for plastic film cutting

Abstract

The invention discloses a distance-adjustable fixed-distance point-breaking type cutting device for plastic film cutting. The distance-adjustable fixed-distance point-breaking type cutting device comprises a machine base. A transmission window fixing base is arranged at the other end of the top of the machine base. A plastic film channel is arranged at the top of the transmission window fixing base. A plurality of conveying rollers are movably mounted in the plastic film channel. A transmission motor of the conveying rollers is arranged in the plastic film channel. A motor fixing base is fixedly mounted at the upper end of the plastic film channel. A motor is fixedly mounted at one end of the motor fixing base. A rotary disc is mounted at a transmission shaft of the motor and fixedly mounted through a replacement bolt. A circular groove is formed in one wall of the rotary disc. According to the distance-adjustable fixed-distance point-breaking type cutting device, through the design ofa pressing block, plastic films are pressed during cutting, so that the tension between the plastic films is stable, and cutting is more stable; and through the arrangement of a first connecting rodand a second connecting rod, the distance of cutting points of the plastic films can be set at will, and convenience and rapidness are achieved.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a fixed-distance point-breaking type incision device with adjustable distance for plastic film incision. Background technique [0002] The plastic film is processed at the end, for the convenience of the user in the follow-up use, the plastic film is processed with a point-break type cutter to form a cut that is easy to tear on the plastic mold, and in the subsequent use process, Facilitates the separation of plastic films. [0003] The existing point-off incision mechanical equipment is convenient for cutting the tangent point of the plastic film at different distances. Most of them are controlled by the speed of the motor. The speed control of the motor is different from the control of the mechanism. Changes, voltage or physical reasons, the position and direction of the tangent point change, it may occur that when the plastic film is cut, the tension between the plastic film...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that the cutting point position of the cutting machine in the related technology is prone to shift, and the tension between the plastic films is too large or too small, resulting in uneven cutting and too small cutting stroke
