Description

Technical Field

[0001] This application relates to the field of polyamide filament production. Specifically, it relates to a drawing and shaping device for polyamide filaments. Background Art

[0002] Polyamide filament is a kind of textile fabric, with various types such as monofilament, ply yarn, and special yarn. Compared with the gloss of real silk fabric, the gloss of polyamide filament fabric is relatively poor. In daily life, polyamide filament fabrics are mainly used to make sportswear, scarves, etc. After polyamide filaments are produced, they need to be drawn, stretched, and shaped. In the related technology of drawing and shaping devices for polyamide filaments, the drawing and stretching structure is relatively simple. On the one hand, the drawing and stretching rollers are fixedly arranged, and the positions of the drawing and stretching rollers cannot be adjusted, so the force of drawing and stretching cannot be adjusted. On the other hand, the structure of the drawing and stretching rollers is relatively simple. When drawing and stretching, the polyamide filaments are prone to displacement on the surface of the drawing and stretching rollers. When drawing and stretching multiple polyamide filaments, the situation of multiple polyamide filaments winding around each other easily occurs, which is not conducive to the simultaneous drawing and shaping of multiple polyamide filaments, and the practicability is relatively low.

The two first connecting blocks 131 are respectively slidably connected inside the two connecting through grooves 113. The two first connecting blocks 131 are respectively threadedly sleeved on the rod bodies of the two first threaded rods 120.

[0028] Please refer to Figure 1-4 , the limiting assembly 200 includes a second stretching roller 210 and an elastic member 220. The second stretching roller 210 is slidably connected to the connecting plate 110. A sliding groove 114 is opened on the plate body of the connecting plate 110. The two connecting through grooves 113 are symmetrically arranged on both sides of the sliding groove 114. One end of the second stretching roller 210 is rotatably provided with a second connecting block 211. The second connecting block 211 is slidably connected inside the sliding groove 114. A limiting slide rod 212 is arranged on the lower surface of the second connecting block 211. The limiting slide rod 212 is slidably inserted into the inside of the plate body of the connecting plate 110.

[0029] In this embodiment, a second threaded rod 230 is rotatably arranged on the upper surface of the second connecting block 211. The second threaded rod 230 rotatably penetrates through the top end of the sliding groove 114, and a second rotating handwheel 231 is arranged at the top end of the second threaded rod 230.

[0030] Specifically, a third connecting block 232 is threadedly sleeved on the rod body of the second threaded rod 230. The third connecting block 232 is slidably connected to the inside of the sliding groove 114. A limiting roller 240 is rotatably connected to the block body of the third connecting block 232. The limiting roller 240 is located above the second stretching roller 210, and the limiting roller 240 is rotatably attached to the second stretching roller 210.

[0031] In this application, the second stretching roller 210 is connected to the elastic member 220. The elastic member 220 is connected to the connecting plate 110. The second connecting block 211 is connected to the top end of the elastic member 220. The bottom end of the elastic member 220 is fixedly connected to the bottom wall of the sliding groove 114.

[0033] Specifically, the working principle of the draw setting device for nylon filaments: During use, the second rotating handwheel 231 and the second threaded rod 230 can be rotated. The second threaded rod 230 drives the third connecting block 232 to move upward, and then drives the limiting roller 240 to move upward. Then, the nylon filaments can be passed through below the two first stretching rollers 130 and above the second stretching roller 210. The nylon filaments can be arranged inside the limiting grooves 300. Then, the second threaded rod 230 is rotated to drive the limiting roller 240 to move downward, so that the limiting roller 240 is rotatably attached to the second stretching roller 210, and then the nylon filaments are sealed inside the limiting grooves 300. Then, the two first rotating handwheels 121 and the two first threaded rods 120 can be rotated. The two first threaded rods 120 can drive the two first stretching rollers 130 to move upward or downward, and then adjust the distance between the first stretching roller 130 and the second stretching roller 210, and then adjust the force of traction and stretching setting. The second connecting block 211 can compress the elastic member 220 downward, and the elastic member 220 can contract, and then the second stretching roller 210 can move downward, and then it is not easy to cause the nylon filaments to break due to excessive force of traction and stretching setting. By rotating the first threaded rod 120, the force of traction and stretching setting can be adjusted. Through the plurality of limiting grooves 300, a plurality of strands of nylon filaments can be traction-stretched. The nylon filaments are not likely to be wound around each other inside the limiting grooves 300, which is beneficial to simultaneously perform draw setting on multiple strands of nylon filaments, and the practicability is relatively high.
