[0002] A loom is a mechanical device used to make fabrics. The weft yarns and warp yarns are interwoven together through the fabric mechanism on the loom to form fabrics of different types and patterns. During the operation of the loom, some irregular or loose edges will be produced. These edges usually do not meet the required size and quality standards, so the woven fabric must be trimmed.

[0003] Patent publication number CN219568210U discloses a trimming device for a loom. By setting an adjustment mechanism, personnel can adjust the height of the trimming mechanism conveniently, thereby reducing the limitations of the device. The trimming device for a loom can increase the support area and friction between the pillar and the ground by setting a support mechanism, thereby improving the support stability of the pillar and ensuring the normal trimming operation of the trimming device. The device has a simple structure and strong practicality.

[0004] When the above-mentioned and similar technical solutions are used to cut woven fabrics, different design requirements require the woven fabrics to be cut into different shapes. When the woven fabrics need to be cut into multiple shapes, it is often necessary to use different cutting devices to cut the woven fabrics, or after the first round of cutting is completed, use other shaping equipment to shape the cut edges of the woven fabric into other shapes, which is a cumbersome operation.

[0024] like Figure 2-Figure 3 As shown, the inner wall of the top relative to one end of the vertical plate 4 is rotatably connected with a rotating plate 603, and the outer wall of one end of the rotating plate 603 is fixedly connected with a plurality of blocks 604, the top and bottom outer walls of the blocks 604 are fixedly connected with a vertical rod 605, the cross bar 607 is slidably sleeved on the circumferential outer wall of the vertical rod 605, and the top and bottom outer walls of the cross bar 607 are fixedly connected with a return spring 606 sleeved on the outer wall of the vertical rod 605, the top outer wall of the vertical plate 4 is fixedly connected with a top plate 601, and the bottom outer wall of the top plate 601 is fixedly connected with a hydraulic cylinder 602, and the first gear plate 8 is fixedly connected to one of the rotating plates 603.

[0025] It should be noted that when it is necessary to trim the woven fabric, the hydraulic cylinder 602 is started to squeeze the cross bar 607 downward at the same time and drive the entire cross bar 607 to descend. At this time, the first cutting plate 608 or the second cutting plate 609 below can trim the woven fabric placed on the top of the support table 2. After the trimming is completed, as the hydraulic cylinder 602 is recovered, the cross bar 607 will be reset under the action of the reset spring 606, thereby achieving the effect of rapid trimming. When the trimming style needs to be changed, the entire cross bar 607 can be driven to rotate by rotating the limit assembly 5, and the position of the first cutting plate 608 and the second cutting plate 609 can be adjusted, thereby achieving the effect of rapid change of the trimming style.

[0026] like Figure 4 As shown, the fixing assembly 7 includes a plurality of fastening springs 701 , and the fastening springs 701 are respectively fixedly connected to the top and bottom outer walls of both ends of the crossbar 607 , and the bottom outer walls of the fastening springs 701 are fixedly connected with fastening plates 702 .

[0027] It should be noted that when the crossbar 607 descends for cutting, the fastening plate 702 will first contact the braid and, under the action of the fastening spring 701, compress the braid to prevent the braid from twisting and tangling during the cutting process.

[0029] It should be noted that when rotating the rotating rod 501, the limiting plate 502 can be inserted into the top of the rotating rod 501, thereby achieving a limiting and fixing effect on the rotating rod 501, so that the first cutting plate 608 and the second cutting plate 609 can remain in a face-down state to facilitate cutting.

[0031] It should be noted that when the rotating rod 501 is rotated and drives the cross bar 607 to rotate, as the first cutting plate 608 and the second cutting plate 609 are changed, under the action of the first toothed disc 8 and the second toothed disc 9, the rotating base 302 can rotate at the same time and adjust the cutting groove to a state matching the first cutting plate 608 and the second cutting plate 609, which is more convenient for cutting.

[0032] like Figure 1-Figure 2 As shown, the outer wall of the rotating base 302 is a circular structure, and the rotating base 302 is matched with the outer wall of the other side of the supporting platform 2.

[0033] Working principle: when it is necessary to trim the woven fabric, the hydraulic cylinder 602 is started to squeeze the cross bar 607 downward at the same time and drive the entire cross bar 607 to descend. At this time, the first cutting plate 608 or the second cutting plate 609 below can trim the woven fabric placed on the top of the support platform 2. After the trimming is completed, as the hydraulic cylinder 602 is recovered, the cross bar 607 will be reset under the action of the reset spring 606. When the rotating rod 501 is rotated and the cross bar 607 is driven to rotate, as the first cutting plate 608 and the second cutting plate 609 are changed, under the action of the first toothed disc 8 and the second toothed disc 9, the rotating base 302 can rotate at the same time and adjust the cutting groove to a state matching the first cutting plate 608 and the second cutting plate 609. When the cross bar 607 descends for cutting, the fastening plate 702 will first contact the woven fabric and, under the action of the fastening spring 701, the woven fabric will be pressed.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
