[0002] In the field of warp knitting machine technology, yarn clamping and cutting are key aspects affecting production efficiency and product quality. Traditional warp knitting machines use a weft selection carriage to place the yarn onto a chain clamping device and then use the chain to transport the yarn. However, yarn cutting is mostly done manually or with a separately controlled cutting device, which is inefficient, labor-intensive, and costly. Furthermore, during the cutting process, the yarn may shift due to the shaking of the equipment, making it difficult to cut effectively. Summary of the Invention

A second spring 34 is pressed between the first protrusion 311 and the second protrusion 331. The second spring 34 realizes the reset of the rotating bent plate 33.

[0020] In addition, the first frame 01 is symmetrically provided with a first movable port 011 for the movement of the electric cylinder connecting plate 053, and a second movable port 012 for the movement of the adjustment system 4 is provided between the first movable ports 011 on both sides. The second movable port 012 is provided with a limiting support frame 013 for supporting the adjustment system 4 on the side wall surface below the thread cutting assembly 2. Both the first frame 01 and the second frame 02 are provided with a chain 03, a drive system 05, and a thread clamping assembly 1. Both the first frame 01 and the second frame 02 are symmetrically provided with chain drive blocks 04 for cooperating with the chain 03 for transmission. Both are located on one side of the frame of the first frame 01 and the second frame 02 and are equipped with infrared monitoring probes 06 for monitoring the yarn. The second frame 02 is symmetrically provided with a third movable port 021 for the movement of the electric cylinder connecting plate 053. The infrared monitoring probes 06 are used to monitor whether the thread clamping assemblies 1 on both sides are clamping the yarn.

[0021] Furthermore, the drive system 05 includes servo electric cylinders 051, which are symmetrically and vertically arranged below the first movable port 011 and the third movable port 021. A piston rod mounting head 052 is mounted on the piston rod at the output end of the servo electric cylinder 051. Electric cylinder connecting plates 053 are horizontally mounted on the piston rod mounting heads 052 on both sides. A slider connecting plate 054 is vertically connected to the front side of the electric cylinder connecting plate 053. The slider connecting plate 054 is mounted on sliders 055 on both sides. The sliders 055 slide and cooperate with the slide rail 056. A first pusher plate 057 is provided on the top of the slider connecting plate 054. First pusher rollers 0571 are rotatably arranged evenly along the horizontal direction on the first pusher plate 057. The first pusher rollers 0571 are used to squeeze the wire clamping assembly 1.

[0022] In addition, the clamping block 13 is rotatably mounted on the clamping seat 12 by the torsion spring 14, and the torsion spring 14 realizes the reset of the clamping block 13, so that the clamping block 13 presses the yarn onto the clamping seat 12.

[0023] Meanwhile, the wire cutting assembly 2 includes a blade engagement arm 21, a blade arm 22, and a third spring 23. The blade engagement arm 21 is vertically mounted on the wire cutting mounting block 111. The blade arm 22 is rotatably engaged with the blade engagement arm 21 in the middle. A third spring 23 is provided between the blade arm 22 and the blade engagement arm 21 to press and reset the rotated blade arm 22.

[0024] The blade arm 22 has a limiting part 224 at the bottom for being pushed by the adjustment system 4, a fourth protrusion 222 on the middle side wall of the blade arm 22, a blade mounting groove 223 at the top of the blade arm 22, a blade 221 for cutting yarn is installed in the blade mounting groove 223, the blade 221 is used to cut yarn, and a disc spring 24 is provided between the blade arm 22 and the clamping seat mounting plate 112.

[0025] Furthermore, the bottom side wall of the blade engagement arm 21 is connected to a third protrusion 211, and the two ends of the third spring 23 are respectively sleeved on the third protrusion 211 and the fourth protrusion 222. The top of the blade engagement arm 21 is pressed and installed with a double blade holder 213 by a blade pressure plate 212. The blade 221 rotates into the double blade holder 213. The double blade holder 213 has symmetrical blades 2132 on both sides. The double blade holder 213 has a slot 2131 between the two blades 2132 for the blade 221 to move in. The sharp blades 2132 on both sides of the double blade holder 213 work with the blade 221 to ensure that the yarn is completely cut.

[0026] Meanwhile, the adjustment system 4 includes a pressure roller 41, which is rotatably mounted on the electric cylinder connecting plate 053. A support plate 43 is rotatably mounted below the pressure roller 41. The support plate 43 rotates through a rotating seat 42 mounted on the first frame 01. One end of the upper surface of the support plate 43 is pressed against by the pressure roller 41, and the other end is rotatably mounted with a support roller 431. A limiting support frame 013 is pressed against the bottom of the support plate 43 to prevent the front end of the support plate 43 from falling.

[0027] Furthermore, the support plate 43 abuts against the pusher connecting plate 44, and the pusher connecting plate 44 is vertically slidably fitted on the reset frame 45. The reset frame 45 is installed below the chain drive block 04 at the top of the first frame 01. The pusher connecting plate 44 includes a sliding plate 441, which is slidably fitted on the reset frame 45. A second pusher plate 442 is horizontally fixedly connected to the top of the sliding plate 441. Second pushers 443 are evenly arranged and rotatably mounted on the second pusher plate 442. The second pushers 443 are used for... At the compression limiting part 224, the reset frame 45 includes an upper mounting plate 451, which is installed at the bottom of the chain drive block 04. Slide rods 452 are symmetrically and vertically arranged at the bottom of the upper mounting plate 451. Slide plate 441 is slidably fitted on slide rods 452. Each slide rod 452 is fitted with a first spring 453. The top of the first spring 453 abuts against the upper mounting plate 451, and the bottom of the first spring 453 abuts against the slide plate 441. The first spring 453 ensures that the push wheel connecting plate 44 can descend and reset.

[0028] In this embodiment, when the yarn is transferred to the warp knitting machine, the yarn is clamped by the clamping assembly 1 on the first frame 01 and the second frame 02. The piston rod is extended by the servo electric cylinder 051, so that the piston rod mounting head 052 cooperates with the electric cylinder connecting plate 053 to drive the slider connecting plate 054 to cooperate with the slider 055 to slide vertically on the slide rail 056. This causes the first push roller plate 057 to contact the clamping assembly 1 on both sides. The first push roller 0571 presses the clamping block 13, causing the clamping block 13 to rotate and press the torsion spring 14, so that the clamping block 13 and the clamping seat 12 are opened to facilitate the weft selection device for feeding the yarn to place the yarn on the clamping assembly 1 on both sides.

[0029] When the weft selection device places the yarn onto the clamping components 1 on both sides, the yarn will come into contact with the rising pressing components 3 during its descent. During this process, the yarn presses down on the rotating bending plate 33, causing the rotating bending plate 33 to rotate downwards. The second spring 34 compresses and contracts. As the yarn descends, the yarn no longer presses down on the rotating bending plate 33, placing it below the rotating bending plate 33. The rotating bending plate 33 is no longer restricted by the yarn, and the second spring 34 releases its elastic potential energy, thereby resetting the rotating bending plate 33 and holding it in place by the limiting head 32. At this point, after the yarn is placed, the infrared monitoring probe 06 detects the placed yarn and immediately begins to automatically cut the yarn, commanding the drive system 05 to descend and perform the cutting work.

[0030] After the drive systems 05 on both sides are reset, the piston rod of the servo electric cylinder 051 on the first frame 01 continues to contract and descend to cut the yarn. After the electric cylinder connecting plate 053 descends, it drives the pressing assembly 3 to descend synchronously, so that the yarn is pressed down by the rotating bending plate 33, ensuring that the yarn is located between the blade engagement arm 21 and the blade arm 22. The electric cylinder connecting plate 053 descends, so that the pressure roller 41 presses down on the support plate 43. The support plate 43 rotates on the rotating seat 42, thereby lifting the support roller 431 on one side, so that the support roller 431 pushes the sliding plate 441 upward. The sliding plate 441 slides on the sliding rod 452, and causes the first spring 453 to contract. The second push roller plate 442 rises, and the second push roller 443 squeezes the limiting part 224, so that the yarn cutting assembly 2 cuts the yarn.

[0031] After the limiting part 224 is pressed upward, the blade arm 22 rotates and the third spring 23 is compressed. The blade 221 rotates into the slot 2131 and works with the blade part 2132 to cut the yarn. This ensures that the yarn is always cut between the blade arm 22 and the blade engagement arm 21 after the pressing assembly 3 is pressed down, and that the yarn will not come out of the cutting position due to shaking.

[0032] In this invention, the automatic clamping and release of yarn is achieved through the cooperation of the yarn clamping assembly 1 and the drive system 05, resulting in high operational efficiency, reduced manual intervention, and lower labor intensity. Under the control of the adjustment system 4, the yarn cutting assembly 2, through the coordinated action of the blade 221 and the cutting edge 2132 of the double blade holder 213, ensures that the yarn is accurately and thoroughly cut, avoiding yarn waste or uneven ends. The yarn pressing assembly 3 automatically presses down after the yarn is placed, ensuring that the yarn is always between the blade engagement arm 21 and the blade arm 22 before cutting, preventing cutting failure caused by yarn shaking, improving the reliability of the system. Furthermore, the work of clamping and cutting yarn can be completed by the drive system 05 alone, ensuring the synchronization and consistency of the clamping and cutting actions.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
