Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to a feeding mechanism used for cutting knitted trousers. Background Art

[0002] There are many types of knitted trousers on the market. They are popular among people because of their low price and durability. Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. Knitted fabrics are ideal materials for clothing because of their superior properties such as softness, breathability, comfort and good elasticity.

[0003] Knitted fabrics usually need to be cut during the production process, and a feeding structure is required for cutting. When the existing feeding mechanism needs to be refilled, it is necessary to first release the fixing of the feed roller, and then manually remove the feed roller that has been processed from the installation slot, disassemble it, and then move the feed roller to be processed to insert its two ends into the installation slot respectively, so that the feed roller is installed on the machine body to complete the refilling. This refilling method is carried out manually, which is very time-consuming and labor-intensive, and it is not convenient to refill the machine body. For this reason, we propose a feeding mechanism for cutting and processing knitted trousers. Utility Model Content
