Description

Technical Field

[0001] This application relates to the field of polyamide production. Specifically, it relates to a twisting device for high flame-retardant polyamide production. Background Art

[0002] Polyamide fiber, scientifically named polyamide fiber, is the general term for polymers with repeating amide groups in the main molecular chain when used as fibers. Internationally, it is called nylon or nylon. Since Jinzhou Chemical Fiber Factory is the first synthetic polyamide fiber factory in China, it is named "polyamide" in China.

[0003] The patent document with the publication number CN114672903B discloses a twisting device for polyamide fiber spinning, belonging to the technical field of spinning and twisting. To solve the problems that most existing twisting devices have complex structures, complicated spinning wire traction methods, which easily cause the twisted wire to bend and the wire body to be unsmooth, thus easily resulting in uneven twisted wires, and the traction direction and traction angle of most twisting devices are always in a fixed state, and the toughness of various spinning wires is different; through the continuous twisting of four groups of spinning wires, the twisting process of the spinning wires is completed, and the winding mechanism winds the twisted spinning wires. By intermittent twisting, the smoothness of twisting is improved, making the twisting more uniform, and the twisting process remains upright.

[0004] In the above application document, the elastic force of the connecting spring can be used to spontaneously adjust the angle of the traction strip plate. The rounded end of the L-shaped arc pulling groove can reduce the friction force of the spinning wire. According to the toughness of the spinning wire, through the cooperation of the guiding mechanism and the traction mechanism, it is convenient to adjust the overall traction angle and traction direction of the device. However, after twisting is completed and winding is carried out, it is easy to produce uneven winding, which is not conducive to later use. Utility Model Content

[0023] Refer to Figure 1-Figure 4 , this embodiment provides a twisting device for the production of high flame-retardant polyamide fiber, including a bottom plate 1, which serves as the basic support structure of the entire twisting device and provides a stable installation platform for other components. The upper end of the bottom plate 1 is fixedly connected with a C-shaped plate 2. A through hole 3 is opened at the upper end of the C-shaped plate 2. A winding device is arranged at the upper end of the C-shaped plate 2. The winding device includes two fixed blocks 41. A reciprocating screw rod 42 is rotatably connected between the two fixed blocks 41. A connecting block 43 is threadedly connected to the outer wall of the reciprocating screw rod 42. The upper end of the connecting block 43 is fixedly connected with a guide sleeve 44. The outer wall of one of the fixed blocks 41 is fixedly connected with a motor 45. The output end of the motor 45 is fixedly connected with the reciprocating screw rod 42.

[0024] A chute 46 is opened at the upper end of the C-shaped plate 2. The bottom of the connecting block 43 is fixedly connected with a slide bar 47. The bottom of the slide bar 47 is slidably connected inside the chute 46, which is used to guide and limit the movement path of the slide bar 47.

[0025] A winding roller 48 is arranged at the upper end of the C-shaped plate 2, which is the component for finally collecting the polyamide fiber.

[0026] When the above-mentioned equipment is used in practice, after the nylon yarn is twisted, it is wound up, and the nylon yarn is passed through the inside of the guide sleeve 44 and wound around the outer wall of the winding roller 48 for winding. The motor 45 is started to drive the reciprocating screw rod 42 to rotate, and then the connecting block 43 threadedly connected to its outer wall will move back and forth left and right. At the same time, the sliding rod 47 at the bottom of the connecting block 43 will slide inside the slide groove 46, thereby ensuring the stability of the connecting block 43 when moving, so as to ensure that the nylon yarn is evenly wound around the outer wall of the winding roller 48 after twisting.
