[0003] Hemp raw materials have relatively coarse and hard fibers with a low degree of fiber splitting, which makes it easy for hemp slivers to run on the combing needles, failing to achieve the functions of combing and stretching, and causing serious blockage of hemp fibers. This severely affects product quality and yield, and makes it difficult to retract, stretch, and pull the hemp slivers. Utility Model Content
[0004] The purpose of this invention is to provide an improved structure for the floating needles of a flax spinning drawing frame, in order to solve the problems raised in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved structure for floating needles in a flax spinning drawing frame, comprising a combing plate and a worktable. A distance adjustment mechanism is provided at the bottom of the combing plate. The distance adjustment mechanism includes a support rod. The support rod is fixedly connected to the bottom of the combing plate, and a first fixing block is fixedly connected to the top of the support rod. A first sliding groove is formed inside the first fixing block, and a first slide rail is fixedly connected inside the first sliding groove. A first slider is slidably connected to the outer wall of the first slide rail, and a feeding shaft is fixedly connected to one side of the first slider. One side of the first fixing block... A support plate is fixedly connected to the side, and a first motor bracket is fixedly connected to both sides of the support plate. A first motor is fixedly connected to the inner side of the first motor bracket. The output shaft of the first motor is fixedly connected to a first motor shaft via a coupling. The outer wall of the first motor shaft is connected through one end of the support plate. A ball screw is fixedly connected to one end of the first motor shaft. One end of the ball screw is rotatably connected to the inner side of the support plate. A ball nut is movably connected to the outer wall of the ball screw. A connecting rod is fixedly connected to the outer wall of the ball nut. The bottom of the connecting rod is fixedly connected to the top of the first slider.
[0006] As a preferred technical solution, there are two first fixing blocks, and the two first fixing blocks are symmetrically arranged with the vertical center line of the feeding axis as the axis of symmetry.
[0007] As a preferred technical solution, a second fixing block is fixedly connected to the top of the workbench, and a second sliding groove is provided inside the second fixing block.
[0008] As a preferred technical solution, a second slide rail is fixedly connected inside the second slide groove, and a second slider is slidably connected to the outer wall of the second slide rail. The top of the second slider is fixedly connected to the bottom of the comb plate.
[0009] As a preferred technical solution, connecting plates are fixedly connected to both sides of the workbench, and an electric push rod is fixedly connected to one side of the connecting plate. One end of the electric push rod is fixedly connected to one side of the comb plate.
[0010] As a preferred technical solution, the top of the workbench is provided with a retraction and traction mechanism, which includes a fixed plate. The fixed plate is fixedly connected to the top of the workbench, and a rotating shaft is rotatably connected to the inner side of the fixed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the setting of a distance adjustment mechanism, can achieve the function of adjusting the distance between the feed shaft and the comb plate. During use, by starting the first motor to drive the feed shaft to move, the feed shaft is adjusted to a suitable position, so that the distance between the feed shaft and the comb plate is reduced, the uncontrollable stretching zone is reduced, which is conducive to the comb needles piercing the hemp strip. It can avoid the situation that the comb plate cannot effectively grasp the fiber due to the inability to adjust the distance between the feed shaft and the comb plate, resulting in incomplete combing and insufficient straightening and parallelism of the fiber, thus ensuring the combing effect of the device.
[0015] 2. This utility model, through the setting of the take-up and release traction mechanism, can facilitate the take-up and release traction of hemp strips. During use, by starting two second motors to drive the take-up and release drum to rotate, the hemp strips are taken up and released. The number of teeth of the first gear is changed from 36 teeth to 32 teeth, keeping the original comb box transmission speed unchanged, reducing the feeding speed, and keeping the number of needle plate strikes unchanged. The principle of slow feeding and fast combing is used to improve the floating needle problem, making the device highly practical. Attached Figure Description

Connecting plates 9 are fixedly connected to both sides of the worktable 4. An electric push rod 10 is fixedly connected to one side of the connecting plate 9. One end of the electric push rod 10 is fixedly connected to one side of the comb plate 1. A retraction and release traction mechanism 3 is provided at the top of the worktable 4.
[0026] When this device is needed, the distance between the feed shaft 206 and the comb plate 1 needs to be adjusted according to the actual situation. The distance adjustment mechanism 2 is used to adjust the distance between the comb plate 1 and the feed shaft 206. Then, the hemp strip needs to be wound and pulled. The wound and pulled mechanism 3 is used to wound and pull the hemp strip. During the wound and pulled process, two electric push rods 10 are activated, so that the two electric push rods 10 wound and released at the same time, and the comb plate 1 began to move back and forth. During the movement, the second slider 8 slides in the second slide rail 7, which makes the movement of the comb plate 1 more stable and smooth. Through the wound and pulled mechanism 3 and the feeding of the feed shaft 206, the combs on the comb plate 1 comb the hemp strip, thus completing the work.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a distance adjustment mechanism 2 is provided at the bottom of the comb plate 1. The distance adjustment mechanism 2 includes a support rod 201. The support rod 201 is fixedly connected to the bottom of the comb plate 1. A first fixing block 202 is fixedly connected to the top of the support rod 201. A first sliding groove 203 is opened inside the first fixing block 202. A first slide rail 204 is fixedly connected inside the first sliding groove 203. A first slider 205 is slidably connected to the outer wall of the first slide rail 204. A feeding shaft 206 is fixedly connected to one side of the first slider 205. A support plate 207 is fixedly connected to one side of the first fixing block 202. A first motor bracket 208 is fixedly connected to both sides of the support plate 207. The inner side of the first motor bracket 208 is fixedly... A first motor 209 is connected, and the output shaft of the first motor 209 is fixedly connected to a first motor shaft 210 via a coupling. The outer wall of the first motor shaft 210 is connected through one end of the support plate 207. A ball screw 211 is fixedly connected to one end of the first motor shaft 210. One end of the ball screw 211 is rotatably connected to the inner side of the support plate 207. A ball nut 212 is movably connected to the outer wall of the ball screw 211. A connecting rod 213 is fixedly connected to the outer wall of the ball nut 212. The bottom of the connecting rod 213 is fixedly connected to the top of the first slider 205. There are two first fixing blocks 202, and the two first fixing blocks 202 are symmetrically arranged with the vertical center line of the feed shaft 206 as the axis of symmetry.
[0028] Specifically, when this device is needed, the distance between the feed shaft 206 and the comb plate 1 needs to be adjusted according to the actual situation. At this time, the first motor 209 is started, which drives the first motor shaft 210 to start rotating. The first motor shaft 210 drives the ball screw 211 to start rotating. The ball screw 211 drives the ball nut 212 to move within the ball screw 211. The ball nut 212 drives the connecting rod 213 to start moving. The connecting rod 213 drives the first slider 205 to slide in the first slide rail 204, making the movement of the first slider 205 more stable and smooth. The first slider 205 drives the feed shaft 206 to start moving, thereby moving the feed shaft 206 to a suitable position, thereby shortening or lengthening the distance between the feed shaft 206 and the comb plate 1, thus completing the distance adjustment work.
[0029] like Figure 1 , Figure 6 and Figure 7As shown, a take-up and release traction mechanism 3 is provided on the top of the workbench 4. The take-up and release traction mechanism 3 includes a fixed plate 301. The fixed plate 301 is fixedly connected to the top of the workbench 4. A rotating shaft 302 is rotatably connected to the inner side of the fixed plate 301. A take-up and release cylinder 303 is fixedly connected to the outer wall of the rotating shaft 302. A first gear 304 is fixedly connected to one end of the rotating shaft 302. The first gear 304 is a gear with 32 teeth. A second motor bracket 305 is fixedly connected to the other side of the fixed plate 301. A second motor 306 is fixedly connected to the inner side of the second motor bracket 305. The output shaft of the second motor 306 is fixedly connected to a second motor shaft 307 through a coupling. A second gear 308 is fixedly connected to one end of the second motor shaft 307. The second gear 308 meshes with the first gear 304.
[0030] Specifically: When it is necessary to take in and pull the hemp strip, one end of the hemp strip is fixed to the take-in and pull cylinder 303 on the left side. Then, the hemp strip is passed through the comb needles on the comb plate 1. The other end of the hemp strip is fixed to the take-in and pull cylinder 303 on the right side. Then, the two second motors 306 are started at the same time, so that the two second motors 306 drive the second motor shaft 307 to start rotating. The second motor shaft 307 drives the second gear 308 to start rotating. The second gear 308 drives the first gear 304 to start rotating. The first gear 304 drives the rotating shaft 302 to start rotating. The rotating shaft 302 drives the take-in and pull cylinder 303 to start rotating. So that the two take-in and pull cylinders 303 rotate in the same direction, so that the hemp strip moves to the right side, and the hemp strip is taken in, pulled, stretched and pulled, thereby completing the take-in and pull operation.
[0031] The working principle of this utility model is as follows: When this device is needed, the distance between the feed shaft 206 and the comb plate 1 needs to be adjusted according to the actual situation. At this time, the first motor 209 is started, causing the first motor 209 to drive the first motor shaft 210 to start rotating. The first motor shaft 210 drives the ball screw 211 to start rotating. The ball screw 211 drives the ball nut 212 to move within the ball screw 211. The ball nut 212 drives the connecting rod 213 to start moving. The connecting rod 213 drives... The first slider 205 slides within the first slide rail 204, making its movement smoother and more stable. The first slider 205 drives the feed shaft 206 to move, thus moving it to a suitable position to shorten or lengthen the distance between the feed shaft 206 and the comb plate 1, thereby completing the distance adjustment. Then, the hemp strip needs to be wound up and pulled. At this time, one end of the hemp strip is fixed to the left-side winding and unwinding cylinder 303, and then the hemp strip is passed through the comb needles on the comb plate 1. Then the other end of the hemp strip... One end is fixed to the take-up and put-down drum 303 on the right side. Then, two second motors 306 are started simultaneously, causing the two second motors 306 to drive the second motor shaft 307 to rotate. The second motor shaft 307 drives the second gear 308 to rotate, the second gear 308 drives the first gear 304 to rotate, the first gear 304 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the take-up and put-down drum 303 to rotate. This causes both take-up and put-down drums 303 to rotate in the same direction, moving the hemp strip to the right and collecting the hemp strip. The hemp strip is stretched and pulled to complete the winding and pulling work. During the winding and pulling process of the hemp strip, two electric push rods 10 are activated to move the comb plate 1 back and forth. During the movement of the comb plate 1, the second slider 8 slides in the second slide rail 7, which can make the comb plate 1 move more smoothly. Through the winding and pulling mechanism 3 and the feeding shaft 206, the combs on the comb plate 1 comb the hemp strip, thus completing the work.
