Description

Technical Field

[0001] The utility model belongs to the technical field, and particularly relates to a production device for flame-retardant polyamide filaments. Background Technique

[0002] A production device for flame-retardant polyamide filaments is an industrial machine specifically designed for producing polyamide filaments with flame-retardant properties. It usually integrates high-precision machinery and control systems to ensure the quality, uniformity, and flame-retardant performance of the filaments.

[0003] At present, after the production of flame-retardant polyamide filaments is completed, winding is required. However, the winding machines of most devices cannot be adjusted according to the size of the winding disc, and workers need to replace the winding machine, which delays time, results in low production efficiency, and increases the labor of workers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a production device for flame-retardant polyamide filaments. By setting a winding assembly, specifically when a worker sleeves a winding disc on the surface of the second rotating shaft, the second rotating shaft drives the fourth telescopic rod and the limiting plate to move into the second rotating shaft under the pushing pressure, so that the winding disc can be smoothly sleeved. Subsequently, the worker rotates the knob clockwise to drive the threaded rod to move, so that the moving plate presses against the inner ring of the winding disc to fix it, and then starts the second motor to work for winding, solving the problem that after the production of flame-retardant polyamide filaments is completed, winding is required, but the winding machines of most devices cannot be adjusted according to the size of the winding disc, and workers need to replace the winding machine, which delays time, results in low production efficiency, and increases the labor of workers.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a production device for flame-retardant polyamide filaments, including a spraying assembly. A traction assembly is arranged on the left side of the spraying assembly, and a winding assembly is arranged on the left side of the traction assembly. The winding assembly includes a third support plate. A fourth support plate is fixedly connected to the front of the top of the third support plate. A second motor is fixedly connected to the front of the fourth support plate. A second rotating shaft is rotatably connected inside the second motor, and the front of the second rotating shaft is fixedly connected to the output end of the back of the second motor;

[0007] Furthermore, a first notch is opened inside the second rotating shaft. A threaded rod is threadedly connected to the inner wall of the first notch. A knob is fixedly connected to the back of the threaded rod. Four second notches are opened on the outer surface of the second rotating shaft. The four second notches are arranged in a circumferential array. The parts contacted by the inner walls of the four second notches are the same. A moving plate is contacted with the inner wall of the second notch. A fourth telescopic rod is fixedly connected to the front and back of the bottom of the moving plate, and the two fourth telescopic rods are connected with the same parts.

[0008] Further, a second spring is fixedly connected to the top of the fourth telescopic rod. The bottom of the second spring is fixedly connected to a third telescopic rod. The inner wall of the third telescopic rod is slidably connected to the outer surface of the fourth telescopic rod. The bottom of the third telescopic rod is fixedly connected to a limiting plate. The bottom of the limiting plate contacts the outer surface of the threaded rod. Since the movement of the threaded rod will drive the limiting plate and the third telescopic rod to move outward of the second rotating shaft, the inner ring of the winding disc will be squeezed to fix the winding disc on the outer surface of the second rotating shaft.

[0009] Further, the traction assembly includes a first support plate. Both the front and the back of the top of the first support plate are fixedly connected to second support plates. A first rotating shaft is rotatably connected to one side of the two second support plates close to each other. A chute is formed inside the first support plate. A first motor is fixedly connected to the front of the second support plate located on the front side. The front of the first rotating shaft is fixedly connected to the output end of the back of the first motor. Starting the first motor drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first telescopic rod to slide in the groove line on the surface of the first rotating shaft.

[0010] Further, two groove lines, one clockwise and one counterclockwise, are formed on the outer surface of the first rotating shaft. The two groove lines are arranged in a staggered and intersecting manner. A first telescopic rod is slidably connected in the two groove lines. A first spring is fixedly connected to the right side inside the first telescopic rod. When the first spring drives the first telescopic rod to expand and contract and the first rotating shaft continues to rotate, the first rotating shaft will fall into the counterclockwise groove line. At this time, the first telescopic rod continues to slide in the counterclockwise groove line under the resilience of the first spring.

[0011] Further, a second telescopic rod is fixedly connected to the left side of the first spring. The outer surface of the second telescopic rod is slidably connected to the inner wall of the first telescopic rod. A traction disc is fixedly connected to the left side of the second telescopic rod. A traction block is fixedly connected to the outer surface of the traction disc. A slider is fixedly connected to one side of the traction disc close to each other. The bottom of the slider is slidably connected to the inner wall of the chute. The first telescopic rod drives the traction disc to reciprocate on the surface of the first rotating shaft. The traction disc will not rotate under fixation. The reciprocating movement of the traction disc drives the slider to reciprocate in the chute. After passing through the traction silk thread, it can be wound.

[0012] Further, the spraying assembly includes a workbench. Two first support plates are fixedly connected to the left side of the top of the workbench. A first roller is rotatably connected to one side of the two first support plates corresponding to each other. A first spraying frame is arranged above the first roller. The front and the back of the first spraying frame are fixedly connected to one side of the first support plates corresponding to each other. A second roller is arranged above the first spraying frame. The front and the back of the second roller are rotatably connected to one side of the first support plates corresponding to each other. A hair dryer is arranged above the second roller. The front and the back of the hair dryer are fixedly connected to one side of the first support plates corresponding to each other. It starts to work after passing through the top of the third roller and winding around the top of the second roller through the guiding frame. At this time, the first spraying frame and the second spraying frame spray the flame retardant liquid on the silk thread.

[0013] Further, two guiding frames are arranged on the right side of one of the two support plates. The two guiding frames are horizontally arranged up and down. The bottoms of the two guiding frames are fixedly connected to the top of the workbench. Two support plates II are arranged on the right side of the two guiding frames.

[0014] Further, the bottoms of the two support plates II are fixedly connected to the top of the workbench. A roller III is rotatably connected to the corresponding sides of the two support plates II. A spraying frame II is arranged above the roller III. The front and back of the spraying frame II are fixedly connected to the corresponding sides of the support plates II. At this time, the spraying frame I and the spraying frame II spray the flame retardant liquid on the silk thread. Through the adjustment and rotation of the front and back positions of the silk thread by the roller I and the roller III, it is ensured that all surfaces of the silk thread are evenly sprayed with the flame retardant liquid.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting the winding assembly in the utility model, specifically when the staff sleeved the winding disc on the surface of the rotating shaft II, the rotating shaft II drove the telescopic rod IV and the limiting plate to move into the rotating shaft II under the pushing pressure, so that the winding disc was smoothly sleeved. Subsequently, the staff rotated the knob clockwise to drive the threaded rod to move, so that the moving plate produced a mortgaging effect on the inner ring of the winding disc to fix it. Then, the motor II was started to work for winding. The adjustable operation adapted to most winding discs, reduced the number of staff and the replacement of winding machines, greatly improved the work efficiency, and reduced the labor force of the staff.

[0017] 2. By setting the traction assembly in the utility model, specifically when the motor I drives the rotating shaft I to move, the two intersecting groove lines drive the telescopic rod I to reciprocate. The reciprocating movement of the telescopic rod I drives the traction block and the slider to move together. In this way, under the action of the traction disc, the silk thread will be evenly wound on the winding disc, avoiding the situation of the silk thread being wound in a pile and knotted, and reducing the unnecessary labor force.

[0018] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6 As shown, the present utility model is a production device for flame-retardant polyamide filaments, including a spraying assembly 1. A traction assembly 2 is arranged on the left side of the spraying assembly 1, and a winding assembly 3 is arranged on the left side of the traction assembly 2. The winding assembly 3 includes a third support board 311. The front surface of the top of the third support board 311 is fixedly connected with a fourth support board 314. The front surface of the fourth support board 314 is fixedly connected with a second motor 313. The inside of the second motor 313 is rotationally connected with a second rotating shaft 312. The front surface of the second rotating shaft 312 is fixedly connected with the output end of the back surface of the second motor 313;

[0030] A notch one is formed inside the second rotating shaft 312. A threaded rod 316 is threadedly connected to the inner wall of the notch one. A knob 315 is fixedly connected to the back of the threaded rod 316. Four notch twos are formed on the outer surface of the second rotating shaft 312. The four notch twos are arranged in a circumferential array. The components contacted by the inner walls of the four notch twos are the same. A moving plate 321 is contacted with the inner wall of the notch two. Both the front and back of the bottom of the moving plate 321 are fixedly connected with a fourth telescopic rod 319. The connecting parts of the two fourth telescopic rods 319 are the same.

[0031] The top of the fourth telescopic rod 319 is fixedly connected with a second spring 320. The bottom of the second spring 320 is fixedly connected with a third telescopic rod 318. The inner wall of the third telescopic rod 318 is slidably connected with the outer surface of the fourth telescopic rod 319. The bottom of the third telescopic rod 318 is fixedly connected with a limiting plate 317. The bottom of the limiting plate 317 contacts the outer surface of the threaded rod 316. When the staff sleeved the winding disc on the surface of the second rotating shaft 312, the second rotating shaft 312 drives the fourth telescopic rod 319 and the limiting plate 317 to move towards the inside of the second rotating shaft 312 under the pushing force, so that the winding disc can be smoothly sleeved. Subsequently, the staff rotates the knob 315 clockwise to drive the threaded rod 316 to move, so that the moving plate 321 produces a mortgaging effect on the inner ring of the winding disc for fixation. Then, the second motor 313 is started to work for winding. The adjustable operation adapts to most winding discs, reduces the number of staff and the replacement of winding machines, greatly improves the work efficiency, and reduces the labor force of the staff.

[0032] The traction assembly 2 includes a first support plate 211. Both the front and back of the top of the first support plate 211 are fixedly connected with a second support plate 216.

The front of the first rotating shaft 213 is fixedly connected to the output end of the back of the first motor 212.

[0033] Two groove lines, one clockwise and one counterclockwise, are formed on the outer surface of the first rotating shaft 213. The two groove lines are arranged in an alternating and intersecting manner. A first telescopic rod 218 is slidably connected in the two groove lines. A first spring 220 is fixedly connected to the right side of the inner wall of the first telescopic rod 218.

[0034] On the left side of the first spring 220, a second telescopic rod 219 is fixedly connected. The outer surface of the second telescopic rod 219 is slidably connected to the inner wall of the first telescopic rod 218. On the left side of the second telescopic rod 219, a traction disc 217 is fixedly connected. On the outer surface of the traction disc 217, a traction block 221 is fixedly connected. On the side of the traction disc 217 close to each other, a slider 215 is fixedly connected. The bottom of the slider 215 is slidably connected to the inner wall of the chute 214. When the first motor 212 drives the first rotating shaft 213 to move, the two intersecting groove lines drive the first telescopic rod 218 to reciprocate. The reciprocating movement of the first telescopic rod 218 drives the traction block 221 and the slider 215 to move together. In this way, under the action of the traction disc 217, the silk thread will be evenly wound on the winding disc, avoiding the situation of the silk thread being piled up and knotted, and reducing unnecessary labor force.

[0035] The spraying assembly 1 includes a workbench 111. On the left side of the top of the workbench 111, two first support plates 112 are fixedly connected. On the corresponding sides of the two first support plates 112, a first roller 113 is rotatably connected. Above the first roller 113, a first spraying frame 114 is arranged. The front and back of the first spraying frame 114 are fixedly connected to the corresponding sides of the first support plates 112. Above the first spraying frame 114, a second roller 115 is arranged. The front and back of the second roller 115 are rotatably connected to the corresponding sides of the first support plates 112. Above the second roller 115, a hair dryer 120 is arranged. The front and back of the hair dryer 120 are fixedly connected to the corresponding sides of the first support plates 112.

[0036] On the right side of the two first support plates 112, two guiding frames 118 are arranged. The two guiding frames 118 are horizontally arranged up and down. The bottoms of the two guiding frames 118 are fixedly connected to the top of the workbench 111. On the right side of the two guiding frames 118, two second support plates 116 are arranged.

[0037] The bottoms of the two second support plates 116 are fixedly connected to the top of the workbench 111. On the corresponding sides of the two second support plates 116, a third roller 117 is rotatably connected. Above the third roller 117, a second spraying frame 119 is arranged. The front and back of the second spraying frame 119 are fixedly connected to the corresponding sides of the second support plates 116.

[0038] A specific application of this embodiment is as follows: when in use, the staff inserts the winding disk from the back of the second rotating shaft 312. At this time, the movable plate 321 is pushed by the winding disk and drives the telescopic rod 4 319 to move inside the telescopic rod 318. At the same time, the telescopic rod 4 319 squeezes the spring 2 320 and drives the limit plate 317 and the telescopic rod 318 to move inside the second rotating shaft 312, so that the winding disk can be smoothly sleeved on the surface of the second rotating shaft 312. The staff turns the knob 315 clockwise to drive the threaded rod 316 to move toward the front. Since the movement of the threaded rod 316 drives the limit plate 317 and the telescopic rod 318 to move outside the second rotating shaft 312, the inner ring of the winding disk is squeezed to fix the winding disk on the outer surface of the second rotating shaft 312. At this time, the motor 2 313 is started. The winding disc will rotate with the second shaft 312 to reciprocate the winding of the silk thread passing through the traction block 221. When the winding is completed, the worker turns the knob 315 counterclockwise to make the limit plate 317 and the telescopic rod three 318 move toward the inside of the second shaft 312 under pressure. At this time, the winding disc with the winding completed can be removed. The simple, convenient and adjustable operation greatly improves the work efficiency and reduces a lot of labor for the workers. At this time, the worker passes the silk thread through the bottom of the drum 113, passes through the top of the drum 113 through the guide frame 118 and is wound on the bottom of the drum 3 117, and then passes through the top of the drum 3 117 through the guide frame 118 and is wound on the top of the drum 2 115 to start working. 14 and the spray rack 2 119 spray the flame retardant liquid on the silk thread, and the roller 1 113 and the roller 3 117 adjust and rotate the front and back positions of the silk thread to ensure that all sides of the silk thread are evenly sprayed with the flame retardant liquid. Then, when the silk thread passes through the roller 2 115 for transmission, the air dryer 120 will quickly air-dry the sprayed silk thread to ensure the smooth progress of subsequent work. When the silk thread reaches the position of the traction component 2 after spraying and air-drying, the silk thread passes through the traction block 221 inside the traction disk 217 for traction, and when the silk thread passes through the traction block 221, the staff starts the motor 1 212 to drive the rotating shaft 1 213 to rotate, and the rotation of the rotating shaft 1 213 drives the telescopic rod 1 218 to slide in the groove line on the surface of the rotating shaft 1 213. Since the groove line is staggered clockwise and counterclockwise Therefore, when the telescopic rod 218 slides to one end of the groove line, since the rotating shaft 213 is continuously rotating, the inner wall of the groove line in the clockwise direction will squeeze the telescopic rod 218 to move toward the telescopic rod 219, and the movement of the telescopic rod 218 will squeeze the spring 220. When the spring 220 drives the telescopic rod 218 to extend and retract, the rotating shaft 213 continues to rotate, causing the rotating shaft 213 to fall into the counterclockwise groove line. At this time, the telescopic rod 218 continues to slide in the counterclockwise groove line due to the rebound force of the spring 220. Therefore, the telescopic rod 218 drives the traction plate 217 to reciprocate on the surface of the rotating shaft 213. The traction plate 217 will not rotate when fixed. The reciprocating motion of the traction plate 217 drives the slider 215 to reciprocate in the slide groove 214.The silk thread after traction can be wound.,
