Description

Technical Field

[0001] The utility model relates to the technical field of drafting machines, in particular to a pre-drafting machine for processing polypropylene fibers. Background Art

[0002] Drawing is the process of regularly stretching and thinning fiber aggregates (such as slivers, rovings, etc.) during spinning. The loose fiber raw materials are processed into fiber layers or slivers, and then into rovings and fine yarns. They must go through a process of gradual thinning. Therefore, almost every main spinning machine or process has a drawing effect. In the related technology, there is a drawing machine that stretches the chemical fiber products wound on the drawing wheels through a combination of multiple drawing wheels, and adjusts the stretching range through the linear speed ratio of different drawing wheel side walls.

[0003] According to the patent website, a pre-stretching machine for polypropylene fiber processing (authorization announcement CN220376855U) describes "a pre-stretching machine for polypropylene fiber processing, including a machine body, a control panel is fixedly provided on the front of the machine body, a vertical plate is fixedly provided on the top of the machine body, a plurality of stretching wheels are provided on one side of the vertical plate, and a plurality of cleaning structures are provided on one side of the vertical plate."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model provides a mounting seat, a mounting rod, a scraper, a connecting sleeve, a positioning rod and other components. When it is necessary to clean the broken wire and waste wire on the stretching wheel, the positioning rod is pulled outward. When the positioning rod is separated from the positioning hole on the mounting seat, the connecting sleeve is rotated, and the connecting sleeve drives the scraper. When the bottom of the scraper is in contact with the stretching wheel, the positioning rod is reinserted into the positioning hole to position the scraper. Then the air pump is started, which can effectively prevent the waste wire from flying in the air. However, in actual use, the device needs to manually move a single positioning rod to The scraper is pulled outward to disengage the positioning rod from the mounting seat, and the connecting sleeve is rotated, so that the scraper is turned over by the connecting sleeve, so that the bottom of the scraper is fitted with the stretching wheel. Since there are multiple scrapers, they need to be pulled out and turned over one by one manually, and they cannot be turned over synchronously, which easily increases the tediousness of the staff's work. In addition, the device collects waste silk floating in the air through an air pump, and the waste silk collected in the collection frame cannot be quickly and centrally processed, and the cover needs to be opened manually for manual cleaning. Therefore, it is necessary to improve a polypropylene fiber processing pre-stretching machine. Utility Model Content
