Multi-cutting type synthetic leather cutting device and cutting manufacturing process thereof

Abstract

The invention discloses a multi-cutting type synthetic leather cutting device and a cutting manufacturing process thereof. The multi-cutting type synthetic leather cutting device comprises a base, side supporting plates, a top plate, a multi-cutting mechanism and an operation table top. According to the multi-cutting type synthetic leather cutting device and the cutting manufacturing process thereof provided by the invention, two cutting modes are achieved; in the first mode, when the width of synthetic leather is not larger than the cutting width of a middle cutting knife, the middle cutting knife can be directly driven by a telescopic rod to conduct downward cutting; and in the second mode, when the width of the synthetic leather is larger than the cutting width of the middle cutting knife, the middle cutting knife is driven by the telescopic rod to conduct downward cutting and then reset, longitudinal floating plates are driven to move downwards on the inner sides of side supporting plates, then side moving blocks are driven to move downwards, finally, side cutting knives downwards cut the two sides of the synthetic leather, and cutting is completed, so that the two cutting modes are formed, using is more flexible, and cutting can be conducted on the synthetic leather with different widths.

Description

technical field [0001] The invention relates to a multi-cut synthetic leather cutting device and a cutting and manufacturing process thereof. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. It is usually made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. It is very similar and has a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather. It needs to be cut during the production process, but the existing synthetic leather has different widths. When cutting is required, it is often necessary to replace different lengths. The cutting blade is for cutting, and the replacement of the cutting blade is cumbersome. The replacement of the cutter head requires the operator to be very careful, otherwise it will rub the operator's hands and other parts, causi...

The replacement of the cutter head requires the operator to be very careful, otherwise it will rub the operator's hands and other parts, causing certain safety hazards. In addition, frequent replacement reduces production. Efficiency, very inconvenient to use
