[0036] A warp knitting machine with a high-stability yarn break alarm function comprises: a warp knitting machine body 1, an infrared transmitter 2, an infrared receiver 3 and a shock-absorbing connector 4.

[0037] The main body 1 of the warp knitting machine is formed with two support plates 11 with mounting planes in contact with the ground and a fan for providing partial power to the yarn. The purpose of the support plate 11 is to support the entire device, and the fan is to provide power to the yarn. The fan providing power to the yarn is a prior art and will not be elaborated. The mounting planes of the two support plates 11 are both inner surfaces. The infrared transmitter 2 is mounted on the mounting plane. The infrared receiver 3 is mounted on the mounting plane.

[0038] The shock-absorbing connector 4 is used to connect the infrared transmitter 2 and the infrared receiver 3 to the mounting surface through the shock-absorbing connector 4. Thus, the infrared transmitter 2 and the infrared receiver 3 can greatly reduce the frequency of vibration through the shock-absorbing connector 4, so that the laser beam is more stable and the detection effect is improved. The infrared transmitter 2 and the infrared receiver 3 form a sensing straight line, and the sensing straight line is on one side of the yarn; the sensing straight line is located in the air outlet direction of the fan; the infrared receiver 3 is used to control the warp knitting machine body 1 to stop when the yarn is broken, and an alarm is set on the support plate 11, and the alarm sounds an alarm when the machine stops. When the yarn is broken, the fan will blow the yarn outward, and then the yarn will float between the infrared transmitter 2 and the infrared receiver 3, and the infrared receiver 3 can have an unstable reception situation, so this is a signal of yarn breakage, and then the warp knitting machine stops at this time.

[0039] Specifically, the shock-absorbing connector 4 includes: a mounting shell 41, a plurality of connecting plates 42, and a plurality of shock-absorbing pads 43. The mounting shell 41 is used to mount the infrared transmitter 2 and the infrared receiver 3. The shock-absorbing pad 43 is located between the two connecting plates 42 and between the mounting shell 41 and the connecting plate 42. The mounting shell 41, the plurality of connecting plates 42, and the plurality of shock-absorbing pads 43 are connected and fixed in sequence.

[0040] Specifically, a position-avoiding chamber 411 is formed in the installation shell 41 ; and openings 5 ​​are formed in both the connecting plate 42 and the shock-absorbing pad 43 .

[0041] Specifically, a slot 412 is formed in the installation shell 41; an inserting portion 421 is formed on the connecting plate 42 abutting against the installation shell 41; and the inserting portion 421 is inserted into the slot 412. The inserting portion 421 and the slot 412 are inserted and connected by interference fit.

[0042] Specifically, a stopper 422 is formed on the connecting plate 42 ; the stoppers 422 of the connecting plates 42 abut against each other in sequence in a direction away from the mounting shell 41 ; and the inner wall surface of the through opening 5 of the shock-absorbing pad 43 abuts against the stopper 422 .

[0043] Specifically, the connecting plate 42 and the shock-absorbing pad 43 are both provided with a socket 6; the shock-absorbing connector 4 also includes a bottom plate 9; the bottom plate 9 abuts against the connecting plate 42; a plurality of the connecting plates 42, a plurality of the shock-absorbing pads 43 and the bottom plate 9 are penetrated by a bolt, and the bolt is threadedly connected and fixed to the support plate.

[0044] Specifically, a rubber ball 7 is disposed in the avoidance chamber 411 ; after the rubber ball 7 is inserted into the avoidance chamber 411 , the rubber ball 7 abuts against the avoidance chamber 411 to form a shape matching the avoidance chamber 411 .

[0045] Specifically, the openings 5 ​​of the plurality of connecting plates 42 and the openings 5 ​​of the plurality of shock absorbing pads 43 form a shock absorbing chamber 51; a hollow rubber block 8 is arranged in the shock absorbing chamber 51, and the hollow rubber block 8 is filled with liquid. A piston 81 is arranged on the hollow rubber block 8, and the piston 81 is used to seal and open the inside of the hollow rubber block 8 for easy water injection and drainage.

[0046] Specifically, a groove 431 is formed on the shock-absorbing pad 43 ; the shape of the groove 431 is similar to the edge profile of the through opening 5 of the shock-absorbing pad 43 ; and the groove 431 is connected to the insertion hole 6 .

[0047] The purpose of the plurality of shock-absorbing pads 43 is to form a shock-absorbing area between the support plate 11 and the mounting shell 41, so as to reduce the vibration frequency of the mounting shell 41. The rubber ball 7 and the hollow rubber block 8 are used for further shock absorption, and the purpose of the groove 431 on the shock-absorbing pad 43 is to create a gap for shock absorption, so that the shock-absorbing pad 43 can be squeezed during installation, and the deformation degree of the shock-absorbing pad 43 is increased, so as to achieve more shock absorption.
