Description

Technical Field

[0001] The utility model relates to the technical field of silk fabric processing, in particular to a cutting device for silk fabric processing. Background Art

[0002] China is the first country in the world to raise silkworms and reel and weave silk. China has made it radiate brilliant light in clothing, economy, art and culture, and has made silk clothes spread all over the world. The process of weaving raw silk as warp and weft to make silk fabrics is silk weaving. The production processes of various silk fabrics are different, and can be roughly divided into raw weaving and cooked weaving. Raw weaving means that the warp and weft are made into fabrics without refining and dyeing, which is called grey silk. The grey silk is then refined and dyed into finished products. During the silk fabric processing, it needs to be cut into the required length. Therefore, we have introduced a cutting device for silk fabric processing.

The utility model utilizes the hydraulic cylinder to drive the rack plate to move, and at the same time drives the gear to rotate, and the guide rack can be extended and retracted back and forth to continuously collect the cut silk fabrics, avoiding the staff from collecting by hand and improving the safety of the staff. The existing technology has the following problems: 1. When using the existing silk fabric cutting device, the fabric needs to be manually laid flat on the conveying component, which may cause wrinkles on the silk fabric, resulting in poor quality of the cut product; 2. When using the existing silk fabric cutting device, the fabric will be offset when it is pulled from the roller to the bottom of the cutting knife, that is, the end of the silk fabric is not parallel to the fabric roller, resulting in tilted broken edges when cut.

This structure can fix the roller and automatically align it to the center to ensure that the roller is located in the middle of the base. Then, the end of the processed silk fabric is pulled out to the gap between the flattening roller and the base. The motor is started to drive the flattening roller to rotate to pull the silk fabric and slowly transport it away from the roller. This structure can straighten the silk fabric and prevent the silk fabric from deviating, causing the cut edge to be tilted. BRIEF DESCRIPTION OF THE DRAWINGS
