Embodiment 1

[0016] A kind of down-pressing crimping machine for staple fiber production line provided by this embodiment, the structure is as follows: figure 1 As shown, it includes a crimping roller, a machine base 5 and a lower rocker arm 7, and a pair of crimping rollers rotating together are installed on the machine base and the lower rocker arm. The roll includes a curling roller 2 and curling rollers 4 arranged on both sides of the curling roller. The curling rollers at both ends of the curling roller are connected with the base and the lower rocker arm through a rotating mechanism. The rotating mechanism is composed of a power input transmission mechanism 1 and a heating The transmission mechanism at the input end consists of 3; the transmission mechanism at the power input end includes an inner flange 13, an outer flange 14, a bearing bush cover 15, a frame bearing bush 16, a radial load bearing 17 and an axial load bearing arranged at the end of the curling roller shaft. 18. The ...

Embodiment 2

[0020] This example provides a down-pressing crimping machine for a staple fiber production line. On the basis of Example 1, this example can make the chemical fibers heated evenly and prevent the chemical fibers from sticking to the surface of the crimping roller. On the curling roller, it is wear-resistant and has a long service life.

[0021] The composite film includes a PTFE film, one side of the PTFE film is coated with a cross-linked adhesive, and the other side of the PTFE film is sprayed with a nano solution, and the composite film is bonded to the curling roller through the cross-linked adhesive;

[0022]The mass percentage components of the cross-linked adhesive are: 4-methylcyclohexyl isocyanate: 35%, urethane: 9%, α-linolenic acid: 6%, ethoxylated bisphenol A dimethacrylate: 7%, Trimethylolpropane Trimethacrylate: 2%, Benzoyl Peroxide: 3%, Butyl Acrylate: 4%, Crosslinked Acrylate Emulsion: 5%, 2-Hydroxy-1,2 - Diphenyl ethyl ketone: 0.7%, dimethylformamide: 1%, vi...

Embodiment 3

[0025] This example provides a down-pressing crimping machine for a staple fiber production line. On the basis of Example 1, a composite film is pasted on the surface of the crimping roller, so that the chemical fiber can be heated evenly and prevent the chemical fiber from sticking to the On the curling roller, it is wear-resistant and has a long service life.

[0026] The composite film includes a PTFE film, one side of the PTFE film is coated with a cross-linked adhesive, and the other side of the PTFE film is sprayed with a nano solution, and the composite film is bonded to the curling roller through the cross-linked adhesive;

[0027] The mass percent components of the cross-linked adhesive are: 4-methylcyclohexyl isocyanate: 36%, urethane: 10%, α-linolenic acid: 7%, ethoxylated bisphenol A dimethacrylate: 8%, Trimethylolpropane Trimethacrylate: 3%, Benzoyl Peroxide: 4%, Butyl Acrylate: 5%, Crosslinked Acrylate Emulsion: 6%, 2-Hydroxy-1,2 -Diphenyl ethyl ketone: 0.8%, di...

Abstract

The invention discloses a pressing-down type crimping machine for a short fiber production line. The pressing-down type crimping machine comprises crimping rollers, an engine base and a lower swinging arm; a pair of crimping rollers, which rotate by resultant force, are mounted on the engine base and the lower swinging arm; each crimping roller comprises a crimping roller wheel and crimped rolling shafts arranged on the two sides of the crimping roller wheel; and the crimped rolling shafts at the two ends of the crimping rollers are connected with the engine base and the lower swinging arm through rotary mechanisms. By adopting the pressing-down type crimping machine, the problem of a traditional crimping machine that the service life of equipment is short when short fibers are produced is mainly solved; a self-aligning roller bearing is used as a radial loading bearing of equipment and an angular contact ball bearing is used as an axial positioning bearing, so that precision of the crimping rollers is guaranteed when the crimping machine is operated and the playing is not easy to occur; meanwhile, a bearing base mounting manner is abandoned and the bearing is internally mounted by adopting a bearing bush; and in a mounting process, the bearing bush is directly mounted on a mounting base, so that the subsequent installation and overhauling difficulties of the crimping rollers are reduced and accumulated installation errors are reduced.

Description

technical field [0001] The invention relates to a fiber crimping device, in particular to a down-pressing crimping machine for a staple fiber production line, which belongs to the technical field of chemical fiber production equipment. Background technique [0002] At present, with the increasingly fierce market competition, higher requirements are put forward for the quality of staple fibers. In the staple fiber production line, the crimping machine is the core equipment to complete the fiber crimping process, and the crimping performance of the fiber depends on the operation status of the crimping machine. The traditional staple fiber production line uses a down-press crimping machine to produce high-demand bright yarn, and its service life is only about 3 months, which not only cannot meet the fiber crimping process requirements, but also increases production costs due to the short service life. Contents of the invention [0003] The technical problem to be solved by t...
