A multi-cut type synthetic leather cutting device and its cutting manufacturing process

Abstract

The invention discloses a multi-cutting synthetic leather cutting device and its cutting manufacturing process, including a base, a side support plate, a top plate, a multi-cutting mechanism and a work table; the invention realizes two modes of cutting, the first one is When the width of the synthetic leather is not greater than the cutting width of the intermediate cutting knife, the intermediate cutting knife can be directly driven to cut downward through the telescopic rod; the second is when the width of the synthetic leather is greater than the cutting width of the intermediate cutting knife, the The rod drives the middle cutting knife to cut downward, then resets, and then drives the longitudinal floating plate to move downward on the inner side of the side support plate, and then drives the side moving block to move downward, and finally the side cutting knife faces the synthetic leather downward. The two sides of the leather are cut to complete the cutting, thus forming two cutting methods, which are more flexible and can be cut for different widths of synthetic leather.

Description

technical field [0001] The invention relates to a multi-cut synthetic leather cutting device and a cutting manufacturing process thereof. Background technique [0002] Synthetic leather simulates the composition and structure of natural leather and can be used as a plastic product as a substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. It is very similar and has a certain air permeability. It is closer to natural leather than ordinary artificial leather. It needs to be cut in the production process. However, the existing synthetic leather has different widths. The cutting blade is used 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 the operator's hands and other parts will be rubbed, causing certain safety hazards. In addition, frequent replacement reduces product...

Problems solved by technology

[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, causing certain safety hazards. In addition, frequent replacement reduces production. Efficiency, very inconvenient to use
