Material cutting device and method of cloth rolling equipment

Abstract

The invention relates to the technical field of cloth rolling, in particular to a material cutting device and method of cloth rolling equipment. The material cutting device comprises two rotary side plates, two transitional rollers, a material cutting driving mechanism, a long cutter and a cutter driving mechanism. The two transitional rollers are arranged in parallel at an interval. The materialcutting driving mechanism can drive the rotary side plates to rotate so that the transitional rollers can be moved to the position above a driving wind-up roller. The long cutter is arranged between the two rotary side plates and located between the two transitional rollers. The cutter driving mechanism can drive the long cutter to rotate so that the cutting edge can be upwards cocked relative tothe transitional rollers in a protruding mode, and in this way, the cloth material passing the transitional rollers can be cut off. The long cutter can cut off the cloth material in the width direction at a time, the speed is high, the efficiency is high, and the cutting notch is flat and straight. The material cutting device and the driving wind-up roller are arranged coaxially in an integrated mode, work independently and do not affect each other, the layout is compact, and the occupied space of the equipment is small.

Description

Technical field [0001] The present invention relates to the technical field of cloth winding devices, in particular to a material cutting device and a material cutting method of a cloth winding device. Background technique [0002] The winding device is generally a post-processing device for equipment such as non-woven fabric production and cloth printing. When enough fabric is wound on one winding shaft, the next empty winding shaft needs to be replaced to continue work; in order to adapt to automatic production, the existing winding machine has a design for automatic roll change, such as the application publication number The Chinese patent for CN 107892197A discloses a winding machine, which includes an automatic roll changing device, a pre-rolling device, a cutting device, and a winding and unwinding device. The cutting device drives the cutting knife to move from one side of the cloth to the other through a knife seat. Cut on one side. In order to make the cut straight, the...

Problems solved by technology

When enough fabric is wound up on one winding shaft, it is necessary to replace the next empty winding shaft to continue working; in order to adapt to automatic production, the existing winding machine is designed for automatic roll changing, as shown in the application publication number The Chinese patent of CN 107892197A discloses a winding machine, including an automatic roll changing device, a pre-rolling device, a cutting device, and a winding and unloading device, wherein the cutting device drives the cutting knife to move from one side of the cloth to the other through the knife seat. Cutting on one side, in order to make the cut straight, the cloth needs to be suspended or decelerated during cutting, which is inefficient and has a certain adverse effect on the front equipment; the layout of the components of the equipment is scattered and the integration is low, so it needs Occupies a large layout space, and the movement arc of each device is large during the roll change process, which limits the speed of its automatic roll change
