In order to solve the problem, the warp knitting machine of the invention also uses a special looping device; for the looping device:

in the first embodiment, referring to fig. 5 to 9, the looping device includes a grooved needle 21 and a first needle seat 22 for holding the grooved needle 21, a sinker 23 and a second needle seat 24 for holding the sinker 23, a yarn guide needle 25 and a third needle seat 26 for holding the yarn guide needle 25, the grooved needle 21 includes a needle body 27 and a needle core 28 disposed in the needle body 27 and slidably connected with the needle body 27, the needle core 28 and the needle body 27 are designed as an integral type with a sliding fit, and the needle core 28 can be driven to move telescopically by up and down movement of the needle body 27 without supporting and moving the needle core 28 by an independent needle seat.

One end of the needle body 27 is provided with a needle hook 29, one end of the needle core 28 points to the needle hook 29, and the other end is connected with a transverse guide rail 210 in a sliding manner; an inverted splayed guide block 211 is horizontally connected on the guide rail 210 in a sliding way, a support rod 212 is arranged in the middle of the needle core 28, and the support rod 212 is supported by the guide block 211 and moves up and down; a sliding block 213 is arranged on the side surface of the first needle seat 22, and the sliding block 213 is connected with one side of the guide block 211 in a sliding manner; the upper end of the guide block 211 comprises a first plane 2111 at the bottom end of the inverted V shape, a first inclined surface 2112 connected with one side of the first plane 2111 and a second plane 2113 connected with the upper end of the first inclined surface 2112, and the projection length of the first inclined surface 2112 in the vertical direction is equal to the ascending distance of the needle core 28 for sealing the needle hook 29; when the yarn is laid, the supporting rod 212 is on the first plane 2111, and the needle hook 29 is in an open state; when the loop is removed, the support bar 212 is in the second plane 2113 and the needle hook 29 is closed.

An inclined sliding groove 2114 is arranged on the side of the first plane 2111 away from the first inclined surface 2112, and the sliding block 213 is arranged in the sliding groove 2114 and is connected with the sliding groove 2114 in a sliding manner; the inclination angle of the first inclined surface 2112 is larger than that of the sliding groove 2114, so that the movement of the needle core 28 can be accelerated, and the yarn can be effectively prevented from being released from the needle hook 29.

A needle hole 214 sleeved with the needle core 28 is arranged in the needle body 27, the needle hole 214 comprises an avoiding part 2141 in the middle and connecting parts 2142 at two ends, the diameter of the connecting part 2142 is slightly larger than that of the needle core 28, the diameter of the avoiding part 2141 is larger than that of the connecting part 2142, the avoiding part 2141 can reduce the contact area between the needle core 28 and the needle body 27, reduce the friction between the needle body 27 and the needle core 28 and reduce the abnormal clamping of the needle core 28; the needle body 27 is provided with a dust discharge port 215 at the lower end of the avoiding portion 2141, when the needle core 28 retracts into the needle hole 214, the lint foreign matter falls into the avoiding portion 2141 of the needle hole 214, and the dust discharge port 215 can discharge the lint deposited at the bottom of the avoiding portion 2141; the end of the avoiding part 2141 away from the needle hook 29 is inclined downwards and points to the dust outlet 215, and the inclined plane can be more beneficial to discharging the flock.

A cylinder 216 is arranged on one side of the guide rail 210 close to the first needle seat 22, a top block 217 is arranged on the side surface of the first needle seat 22, a top rod 218 connected with the cylinder 216 is arranged on the top block 217, and the top rod 218 is fixedly connected with a piston in the cylinder 216; when the first needle seat 22 ascends, the ejector rod 218 extrudes the piston of the air cylinder 216, so that air in the air cylinder 216 flows to the avoiding portion 2141 from the hose 219, and flock at the bottom of the avoiding portion 2141 is blown away from the dust exhaust port 215; a flow passage 220 is arranged in the needle body 27, an inlet end of the flow passage 220 is connected with the hose 219, the other end of the flow passage 220 is inclined downwards and points to one end of the avoiding portion 2141 far away from the needle hook 29, and the flow passage 220 enables air flow to be blown downwards in an inclined manner, so that the fluff at the bottom of the avoiding portion 2141 can enter the dust exhaust port 215 more conveniently.

The working principle of the looping device in the warp knitting machine is as follows:

during the loop knitting of the grooved-needle warp knitting machine, the second needle seat 24 controls the sinker 23 to move forward, and the needle body 27 is controlled by the first needle seat 22 to move upwards; in the process that the first needle seat 22 moves upwards, the sliding block 213 on the first needle seat 22 drives the guide block 211 to move horizontally, the supporting rod 212 on the needle core 28 moves from the second plane 2113 to the first plane 2111, so that the needle hook 29 is in an open state, when the first needle seat 22 drives the needle body 27 to continuously ascend, the supporting rod 212 moves on the second plane 2113, and the needle core 28 is located inside the needle hole 214; then the third needle seat 26 controls the yarn guide needle 25 to complete yarn laying; in the process that the first needle seat 22 moves upwards, the ejector block 217 on the first needle seat 22 simultaneously pushes the ejector rod 218 to extrude the air cylinder 216, so that air in the air cylinder 216 is compressed, then the compressed air flows into the needle body 27 through the hose 219 and is blown to the flocks at the bottom end of the avoiding portion 2141 through the flow passage 220 in the needle body 27, and the flocks at the bottom end of the avoiding portion 2141 are discharged from the dust discharge port 215; when the dust exhaust port 215 is blocked, the gas in the cylinder 216 cannot be released quickly, the air pressure in the cylinder 216 rises, when the air pressure exceeds the set value of the air pressure sensor 221, the air pressure sensor 221 transmits a signal to a controller of the warp knitting machine, and the controller sends an alarm signal to an operation display interface of the warp knitting machine to remind an operator of cleaning and maintaining in time.

When the needle is dropped and looped, the first needle seat 22 moves downwards, the sliding block 213 on the first needle seat 22 drives the guide block 211 to move horizontally in the opposite direction, the support rod 212 on the needle core 28 moves from the first plane 2111 to the second plane 2113, and the needle hook 29 is in a closed state at the moment; then the first needle seat 22 continues to drive the needle body 27 to move downwards to complete the knocking-over, at this time, the supporting rod 212 is positioned on the second plane 2113, and the needle hook 29 is in a closed state, so that the yarn can be prevented from being disengaged from the needle hook 29 during the knocking-over; when the first needle holder 22 moves downward, the plunger 218 moves downward and pulls the piston in the cylinder 216, so that the cylinder 216 is completely charged for the next cycle.
