Non-woven fabric cutting device

Abstract

The invention discloses a non-woven fabric cutting device. The non-woven fabric cutting device is characterized in that a rack is provided with an unwinding mechanism, a length counter, cloth guide rollers, a liftable cutting assembly and a winding mechanism in sequence from left to right; the liftable cutting assembly is composed of a triangular frame, a chain belt, a double-gear shaft, a liftingdriving device and a transmission chain belt, the left end of the bottom side of the triangular frame is movably connected to the rack through a pin shaft, a cutting blade is arranged on the triangular frame, and the cloth guide rollers are arranged on the two sides of the cutting blade; the lifting driving device drives the double-gear shaft to rotate through the transmission chain belt; the chain belt is connected with the double-gear shaft, springs are arranged at the two ends of the chain belt, and the chain belt is connected with the left end of the bottom side of the triangular frame through the spring at the left end and is connected with the rack through the spring at the right end. The non-woven fabric cutting device is simple in structure, convenient to use, high in cutting precision and suitable for cutting fabric with different sizes.

Description

technical field [0001] The invention relates to the field of non-woven fabric production equipment, in particular to a non-woven fabric cutting device. Background technique [0002] Non-woven fabrics are also called non-woven fabrics, and their manufacturing process is different from the traditional textile process. The biggest feature of non-woven fabrics is that no spinning is required, and the manufacturing process is similar to the papermaking process. After the non-woven fabric is manufactured, it is usually further processed to make the non-woven fabric into non-woven parts of the desired shape. One of the most common methods for deep processing of non-woven fabrics is to slit non-woven fabrics, that is, while using pressure rollers to draw non-woven fabrics, the non-woven fabrics are cut into non-woven fabrics through a cutting die that reciprocates up and down. Spinning parts. If the non-woven fabric is pulled by the pressure roller, there may be slippage between ...

AI Technical Summary

Problems solved by technology

The non-woven fabric is pulled by the pressure roller, and there may be slippage between the non-woven fabric and the pressure roller, which will affect the positioning accuracy of the non-woven fabric cutting

In addition, the slitting die and the pressure roller that reciprocate up and down are not linked, which will also affect the positioning accuracy of the non-woven fabric slitting

Usually, the interval between non-woven parts is increased to make up for the lack of positioning accuracy. This method will generate a large amount of leftovers, resulting in increased costs.
