Description

Technical Field

[0001] The utility model relates to a trimming device for loom weaving, belonging to the technical field of loom weaving. Background Art

[0002] A loom is a machine used to make fabrics by weaving or knitting yarns or other slender materials. Looms can be divided into manual looms and automatic looms. Modern looms have achieved automation and intelligence, and can automatically monitor parameters such as the color, weight, and strength of fabrics, and achieve better fabric quality and higher efficiency through automatic adjustment. After the production of textiles is completed, many textiles have problems such as frayed edges, and thus need to be trimmed.

[0003] There is a trimming device for loom weaving with the patent number CN220643412U. When using this device, the staff pulls out one end of the fabric roll and places it on the workbench, smooths it out, and then starts the first cylinder on the top of the fixed plate. The output end of the first cylinder pushes the lower pressing plate, so that the lower pressing plate presses down on the fabric to fix the fabric and prevent the fabric from shifting during cutting. A long strip trimming hole is opened in the middle of the lower pressing plate to facilitate the cutting saw blade to cut the fabric and cut the excess frayed edges on both sides of the fabric. There are balls at the bottom of the lower pressing plate, so that the fabric can be pulled forward while being positioned and cut. A second cylinder is fixed at the bottom of the workbench. The staff starts the second cylinder, and the output end of the second cylinder pushes the first motor upward. The output end of the first motor drives the cutting saw blade to rotate, so that the cutting saw blade exposes from the side cutting groove to cut the side of the fabric. However, when using this device, although the cutting saw blade can be lifted and lowered, it is also difficult to adjust the position, and thus it is difficult to perform trimming according to the width of the woven fabric, and the cutting size cannot be adjusted during continuous cutting; moreover, the winding structure used in this device is relatively fixed, and it is difficult to quickly disassemble and replace the winding roller after winding, which is not conducive to the disassembly and packaging of the wound fabric.
