Description

Technical Field

[0001] This utility model relates to the field of traction device technology, specifically a filament traction device for flame-retardant fiber processing. Background Technology

[0002] Flame-retardant fiber is a type of fiber material with flame-retardant properties, typically produced by adding flame retardants to the fiber surface or interior, or through special manufacturing processes. Flame-retardant fibers possess properties such as fire resistance, fireproofing, and flame retardancy, effectively slowing the spread of flames and improving the flame retardancy rating of materials. They are widely used in fire-retardant materials, protective clothing, building materials, and other fields to enhance product safety and fire resistance.

[0003] In the production and processing of flame-retardant fibers, a traction device is needed to guide and pull the fiber bundle. Currently, when the fiber bundle becomes taut, the guiding component in contact with it adheres tightly to the bundle, which can easily cause damage or even breakage during movement, affecting the device's effectiveness. Therefore, improvements are needed. Utility Model Content

[0022] Please see Figure 1 , Figure 4 The adjusting mechanism 9 includes a motor 91. A positive and negative screw 92 is fixedly connected to the outer side of the output end of the motor 91. A support seat 93 is rotatably sleeved on the outer side of the positive and negative screw 92 via bearings. The support seat 93 is fixedly connected to the base plate 1. The support seat 93 is designed to provide rotatable support for the positive and negative screw 92.

When the support roller 10 is subjected to force, it can move vertically accordingly, which can avoid the filament bundle from breaking or being damaged when supporting it.

[0024] When the height of the support roller 10 needs to be adjusted, the motor 91 is started.
