The surface of the pressure rod 2 is fixedly connected to a first screw rod 21, and the surface of the first screw rod 21 is threadedly connected to a first nut 22. A socket 23 is provided inside the pressure rod 2. A blade 24 is provided on the surface of the pressure rod 2. A connecting rod 25 is fixedly connected to the surface of the blade 24. A slide groove 26 and a screw hole 27 are provided on the surface of the connecting rod 25. A support plate 28 is fixedly connected to the surface of the side case 1. A fastener 29 is threadedly connected to the surface of the screw hole 27. A "V"-shaped opening is provided on the surface of the blade 24 to make it more convenient and quick for the blade 24 to cut the cloth body 15.

[0028] Furthermore, two groups of pressure rods 2 are provided, one group of pressure rods 2 is fixedly connected to the surface of the side case 1, and the other group of pressure rods 2 is movably connected to the outside of the side case 1. The number of pressure rods 2 in each group is two, and the cross-section of the pressure rods 2 is "L"-shaped. Each group of pressure rods 2 is arranged on both sides of the connecting rod 25. The pressure rods 2 fixed on the side case 1 are in contact with the surface of the cloth body 15. The spacing between each group of pressure rods 2 is the same and allows the blade 24 to move therebetween. When weaving or winding is completed, the group of pressure rods 2 that is movable outside the side case 1 is pressed against the cloth body 15 along the first screw 21. The two groups of pressure rods 2 are pressed against each other to achieve the effect of pressing and limiting the cloth body 15, so as to facilitate cutting by the blade 24.

[0029] Furthermore, one end of the first screw 21 is fixedly connected to the surface of the pressure rod 2, and the other end of the first screw 21 is movably connected to the surface of the socket 23. Two groups of first nuts 22 are provided, and the two groups of first nuts 22 are abutted and connected on both sides of the pressure rod 2. The cross-section of the connecting rod 25 is "T"-shaped. The two groups of pressure rods 2 are connected by the first screw 21, so that one end of the first screw 21 is fixed to the group of pressure rods 2 fixedly connected to the side chassis 1, and the other end is movably connected to the other group of pressure rods 2. At the same time, through the connection between the first screw 21 and the first nut 22, the group of pressure rods 2 that are movable outside the side chassis 1 can be limited, so that the group of first nuts 22 close to the cloth body 15 can achieve a supporting effect on the pressure rod 2, and the group of first nuts 22 close to the fastener 29 can be limited when the two groups of pressure rods 2 are abutted to squeeze the cloth body 15 more firmly.

[0030] Furthermore, the connecting rod 25 is slidably connected to the surface of the support plate 28 through the slide groove 26. The cross-section of the support plate 28 is "U"-shaped. The two ends of the support plate 28 are fixedly connected to the surface of the side chassis 1. The fastener 29 is abutted against the surface of the support plate 28. The blade 24 can cut the cloth 15 by moving the connecting rod 25. At the same time, the connecting rod 25 is moved along the surface of the support plate 28 through the support plate 28 to ensure that the cutting surface is flat. One side of the fastener 29 is in a pancake shape, and the other side is in a rod shape and is provided with threads and screw holes 27 on the surface for connection. Through the connection between the fastener 29 and the screw hole 27, the effect of limiting the connecting rod 25 when not in use can be achieved.

[0031] Furthermore, a pressing mechanism is provided on the surface of the cloth body 15, and the pressing mechanism includes a cross bar 3, both ends of which are fixedly connected to the surface of the side chassis 1, a mounting plate 31 is fixedly connected to the surface of the cross bar 3, a second screw 32 is fixedly connected to the surface of the mounting plate 31, a second nut 33 is threadedly connected to the surface of the second screw 32, and a pressure plate 34 is provided on the surface of the cloth body 15, a through hole 35 is provided on the surface of the pressure plate 34, and the cross bar 3 is fitted and connected to the surface of the cloth body 15. When the cloth body 15 is rolled up, it moves along the surface of the cross bar 3, and under the action of the cross bar 3 and the pressure plate 34, the cloth body 15 is pressed to maintain its flatness before rolling up.

[0032] Furthermore, two groups of mounting plates 31 are provided, and the two groups of mounting plates 31 are arranged at both ends of the cross bar 3, and the number of mounting plates 31 in each group is two. One end of the second screw rod 32 is fixedly connected to the surface of the mounting plate 31, and the other end of the second screw rod 32 is connected to the surface of the pressure plate 34 through the through hole 35. Under the action of the mounting plate 31, the second screw rod 32 is supported, so that the second screw rod 32 can be connected to the pressure plate 34 through the through hole 35.

[0033] Furthermore, two groups of second nuts 33 are provided, and the two groups of second nuts 33 are abutted and connected on both sides of the pressure plate 34, and the pressure plate 34 is abutted and connected on the surface of the cloth body 15. Two groups of through holes 35 are provided, and the two groups of through holes 35 are opened on both sides of the pressure plate 34. The number of through holes 35 in each group is two. Through the action of the two groups of second nuts 33, the abutment effect of the pressure plate 34 on the cloth body 15 can be achieved, and at the same time, the effect of limiting the pressure plate 34 can be achieved, thereby avoiding the situation where the pressure plate 34 squeezes the cloth body 15 excessively and causes difficulty in winding.

[0034] Working principle: After the weaving is completed or when the rapier loom is no longer wound, the first nut 22 close to the cloth body 15 is loosened through a thread to move it to the bottom of the first screw rod 21, and the movable group of pressure rods 2 is pressed against the surface of the cloth body 15 along the first screw rod 21, and then the other group of first nuts 22 is fastened and pressed against the group of pressure rods 2 through threads, and then the two groups of pressure rods 2 are pressed together to achieve the pressing limit of the cloth body 15. At this time, the fastener 29 is rotated so that it no longer presses against the support plate 28, and the connecting rod 25 is moved along the support plate 28 through the slide groove 26 to drive the blade 24 to cut the cloth body 15.

[0035] During the operation of the rapier loom, the cloth body 15 is attached to the cross bar 3 for winding. First, a group of second nuts 33 are connected to the second screw rod 32 by threads, and the two ends of the pressure plate 34 are installed on the second screw rod 32 through the through holes 35. Then, another group of second nuts 33 are connected to the second screw rod 32 by threads, so that the two groups of second nuts 33 are respectively arranged on both sides of the pressure plate 34. At this time, the position of the pressure plate 34 is adjusted to make it abut against the cloth body 15. After abutment, the two groups of second nuts 33 are again abutted against the pressure plate 34 by threads to limit it, thereby realizing the pressing of the cloth body 15 to maintain the surface flatness.
