Problems solved by technology

[0003] In the prior art, since the distance between the two crimping knives cannot be adjusted, the crimping machine can only produce polyester staple fibers with the same degree of crimping
The crimping machine is a high-speed operation equipment, and long-term work will inevitably lead to wear and tear of the crimping wheel and the crimping knife, which will cause errors in the process width on the crimping wheel and the crimping knife
In the prior art, the positions of the crimping wheel and the curling knife are fixed, so to adjust the process width, the entire crimping wheel and the curling knife must be corrected, which not only greatly increases the maintenance time and cost, but also reduces the production efficiency

Embodiment 1

[0027] Such as figure 1 , figure 2 As shown, the novel crimping machine comprises a frame 1 and a crimping box 2, a rotatable upper crimping wheel 3 and a lower crimping wheel 4 are arranged in the crimping box 2, and an upper crimping knife 5 and a lower crimping knife are also provided in the crimping box 2 6. The lower curling knife 6 is fixed below the upper curling knife 5 through a support rod 7. A swing arm 8 is hinged in the curling box 2. The upper curling knife 5 is fixed on the lower end of the swing arm 8 through a locking bolt 9. The middle part of the swing arm 8 There is a through hole, and the side wall of the crimping box 2 is provided with an arc-shaped guide hole 10, and a positioning screw 11 is connected in the through hole, and the inner end of the positioning screw 11 is inserted into the arc-shaped guide hole 10, and the end of the positioning screw 11 has a nut. The nut is located on the outer wall of the crimping box 2.

Embodiment 2

[0036] Such as Figure 6 As shown, the difference from the first embodiment lies in the arrangement of the flow guide grooves 24, and the flow guide grooves 24 of this embodiment are arranged parallel to each other. The length direction of the guide groove 24 is consistent with the moving direction of the fiber tow, which is convenient for collection.

[0037]The bottom surface of last crimping knife 5 and following crimping knife 6 is oppositely arranged, and the gap between the two is suitable with the thickness of tow. The electric heating wire 18 can heat the upper curling knife 5, and also heat and keep warm the steam flowing through the upper curling knife 5 simultaneously. Steam is charged into the steam inlet hole 20 at the tail of the upper crimping knife 5, flows through the steam injection pipeline 19, and is ejected from the steam nozzle 22 on the bottom surface of the upper crimping knife 5 to heat and pre-size the tow passing through. There is a concave steam c...

Abstract

The invention provides a chemical staple fiber crimping machine. The chemical staple fiber crimping machine comprises a rack and a crimping box, wherein a rotatable upper crimping wheel and a rotatable lower crimping wheel are arranged in the crimping box. The chemical staple fiber crimping machine is characterized in that an upper crimping knife and a lower crimping knife are further arranged in the crimping box, the lower crimping knife is fixedly arranged below the upper crimping knife through a supporting rod, a swing arm is hinged in the crimping box, the upper crimping knife is fixed at a lower end of the swing arm through a locking bolt, a through hole is formed in a middle part of the swing arm, an arc-shaped guide hole is formed in a sidewall of the crimping box, a positioning screw is connected into the through hole, an inner end of the positioning screw is inserted into the arc-shaped guide hole, an end portion of the positioning screw is provided with a nut and the nut is located on an outer sidewall of the crimping box. By changing the distance and angle between the upper crimping knife and the lower crimping knife, the crimping pressure can be changed and the goal of controlling the crimping number is achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber processing equipment and relates to a crimping machine for chemical fiber staple. Background technique [0002] The crimping machine is an important forming tool in the production process of polyester staple fiber. The crimping machine mainly consists of two crimping wheels and two crimping knives. The crimping wheels are distributed up and down, and the crimping knife is also distributed up and down and positioned between the two crimping wheels. The pushing force generated by the crimping wheel holding the tow, and the resistance to the tow generated by the pressure between the crimping knives, the combined action of the two makes the tow gradually destabilize, resulting in bending deformation, so that the crimped structure can be formed. The number of crimps is one of the important quality indicators of chemical fiber staple fibers. Generally speaking, the thickness of the tow, the cri...
