Technical Field

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

[0002] Knitted fabrics are divided into two categories according to the weaving method: weft knitted fabrics and warp knitted fabrics. Weft knitted fabrics are often made of low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., and are woven on various weft knitting machines using plain needle structure, variable plain needle structure, rib plain needle structure, double rib plain needle structure, jacquard structure, terry structure, etc. With the advancement of science and technology and the development of society, my country's textile industry has developed rapidly, and with it the rapid development of textile equipment. In the process of textile fabric processing and production, textile fabrics need to be cut frequently.

[0003] However, a cutting device without a cutting positioning function will cause slight displacement of the fabric at the moment the cutter contacts the fabric, resulting in uneven cuts on some fabrics and reduced cutting quality. Therefore, a textile fabric cutting device is proposed. Utility Model Content

The same clamping plate 812 is fixed to the bottom of the multiple vertical rods 811, which squeezes the top rod 808 inward. When one end of the top rod 808 is in contact with the arc groove, the telescopic rod 805 can be pressed down, and the telescopic rod 805 drives the connecting plate 810 and the clamping plate 812 to move downward. When the top rod 808 moves to the position of the positioning hole 809, the second spring 807 pushes the top rod 808 outward, causing it to pop out from the positioning hole 809 to fix the telescopic rod 805. When the clamping plate 812 is in contact with the fabric and the fabric is fixed, the telescopic rod 805 can be stopped from being pressed, replacing the traditional fixing method of bolts and pressure plates, which can improve the efficiency of pressing the fabric.

[0028] Working principle: Before processing, first lay the fabric to be cut flat on the top of the workbench 1, and then adjust the positions of multiple clamping structures 8 according to the specifications of the fabric, pull the pin 803 upwards to adjust the position of the clamping structure 8 by pushing the slider 801, and after the position adjustment is completed, squeeze the top rod 808 inward, and when one end of the top rod 808 fits with the arc groove, the telescopic rod 805 can be pressed down, and the telescopic rod 805 drives the connecting plate 810 and the clamping plate 812 to move downward. When the top rod 808 moves to the position of the positioning hole 809, the second spring 807 pushes the top rod 808 outward, causing it to pop out from the positioning hole 809 to fix the telescopic rod 805. After the fabric is fitted and fixed, you can stop pressing the telescopic rod 805, and then start the cylinder 5 to drive the knife holder 6 to move down to cut the fabric. The knife holder 6 drives the mounting plate 701 to move down, and the mounting plate 701 then drives the slide bar 702 and the positioning plate 706. The positioning plate 706 will first fit with the fabric. After the positioning plate 706 fits with the fabric, it will drive the slide bar 702 to move up, and the slide bar 702 will then drive the limiting ring 704 to move up. When the cutter fits with the fabric and cuts, the limiting ring 704 fits with the bottom of the mounting plate 701, and the slide bar 702 stops moving upward, and the fabric is squeezed and fixed at the moment of cutting, which can effectively prevent the fabric from shifting during cutting and ensure the flatness of the incision.
