Description

Technical Field

[0001] The utility model specifically relates to an anti-winding roller structure of a regenerated polyester fiber winding device, belonging to the technical field of polyester fiber processing. Background Technique

[0002] The production process of polyester fiber spinning is as follows: the polyester melt is extruded in a filamentous form from the fine holes of the spinneret plate of the spinneret assembly, contacts the cooling air blown by the ring blowing device and solidifies into a filament bundle. The filament bundle is bundled by an oiling roller and a gathering roller. After each spinning position is bundled respectively, they are gradually gathered into a flat and neat silk sheet, which is pulled by a tractor and sent to a winding device for winding. Due to the uncontrollability of the regenerated polyester fiber raw materials, when the completed filament bundle is wound, broken filaments and pulp blocks are likely to appear. The head filaments and pulp blocks are very easy to wind around the winding device. If not processed in time, it will affect the quality of the polyester fiber roll; in severe cases, it will lead to the scrapping of the entire polyester fiber roll; therefore, it is necessary to prevent the winding device from winding. The existing anti-winding structures for polyester fibers, such as the anti-winding roller tractor for polyester fiber production disclosed in the Chinese patent authorization publication number: CN215481448U, set a scraping device on the side of the traction roller away from the filament bundle, automatically scraping off the broken filaments wound around the roller, effectively reducing the occurrence of broken filament winding around the roller phenomenon, and ensuring the continuity of polyester fiber production. This structure realizes the peeling of broken filaments through the cooperation of the scraper and the traction roller, but this structure can only process the broken filaments wound on the traction roller, the processing method is relatively lagging, and the processed broken filaments are easily re-entrained inside the filament bundle. Summary of the Utility Model

[0003] To solve the above problems, the utility model proposes an anti-winding roller structure of a regenerated polyester fiber winding device, which uses a metal pressure roller to scrape up the broken filaments. During the scraping process, it can remove static electricity from the entire filament bundle, and at the same time directly perform double-sided broken filament removal on the filament bundle to ensure the smoothness of the entire filament bundle winding.

[0004] The anti-winding roller structure of the regenerated polyester fiber winding device of the utility model includes:

[0005] A guiding roller group, the guiding roller group is arranged at the front end of the winding device, and the guiding roller group includes a first guiding roller and a second guiding roller that are arranged in a vertically staggered and rotating manner on the frame;

[0008] When the winding equipment winds the polyester fiber tow, first wind the fiber tow from the first guide roller to the second guide roller. The fiber tow passes through the guide bin channel. One metal pressing roller presses against the upper surface of the fiber tow, and the other metal pressing roller presses against the lower surface of the fiber tow. As the winding equipment winds up, the fiber tow rubs against the metal pressing roller, and the broken filaments and pulp blocks on the fiber tow can be scraped up. Blocked by the metal pressing roller, the broken filaments and pulp blocks can be guided between the two wire - removing rollers. The anti - wire motor drives one of the wire - removing rollers to rotate, and drives synchronously through the belt to make the two wire - removing rollers rotate towards each other; the broken filaments and pulp blocks pass through the wire - removing rollers and are collected into the material receiving bin. And because one of the wire - removing rollers is close to the fiber tow, for the broken filaments that are not collected, through the cooperation of this wire - removing roller and the metal pressing roller, they are collected inside the material receiving bin.

[0009] Further, the radial cross - section of the metal pressing roller is a cam structure, and the protruding part of the metal pressing roller faces the side of the fiber tow; both ends of the metal pressing roller are provided with ends fixed to the material receiving bin, and internal screw holes are formed on the ends, and a grounding wire is screwed on the internal screw holes; adopting the cam structure can improve the peeling efficiency of the broken filaments and pulp blocks on the fiber tow, and the metal pressing roller is grounded through the grounding wire to eliminate the frictional static electricity on the fiber tow.

[0010] Further, the outer surface of the wire - removing roller is a reticulated structure or a tooth - groove structure; through the reticulated structure or the tooth - groove structure, the broken filaments can be clamped between the wire - removing rollers.

[0011] Further, a brush is fixed to the lower part of the wire - removing roller close to the fiber tow, and the brush is attached to the wire - removing roller; in order to prevent the broken filaments scraped off by the wire - removing roller from approaching the fiber tow, by setting the brush as a safety part, when the wire - removing roller is wound with broken filaments and passes through the brush, the brush can scrape the broken filaments off the wire - removing roller, and the broken filaments are collected inside the material receiving bin.

[0012] Further, a cloth feeding groove is formed in the upper part of the guiding bin channel, and a cover plate is hinged on the cloth feeding groove. The cover plate is magnetically attracted to the guiding bin channel. When it is necessary to wind the fiber bundle from the first guiding roller to the second guiding roller, first open the cover plate to enable the fiber bundle to smoothly pass through the guiding bin channel. Then, close the cover plate.

[0013] Further, the material receiving bin is provided with a discharge chute; a discharge door is hinged to the material receiving bin at the discharge chute; the discharge door is engaged with the material receiving bin through a locking pin. The material receiving bin needs to regularly discharge broken filaments and pulp blocks. First, separate the locking pin from the pin seat, open the discharge door, and discharge the broken filaments and pulp blocks from the material receiving bin. After the discharge is completed, cover the discharge door again and limit and lock the discharge door through the locking pin.

[0014] Further, negative pressure extraction heads are fixed to the inner top of the upper material receiving bin and the inner lower part of the guiding bin channel. The negative pressure extraction heads are connected to a negative pressure source, and the broken filaments lifted are attracted by the negative pressure source to make the broken filaments separate from the fiber bundle; the separation efficiency of the broken filaments and the fiber bundle is improved, and it can prevent the separated broken filaments from re - adhering to the fiber bundle. The broken filaments are guided by a metal pressing roller and introduced into two wire removing rollers. The broken filaments are continuously pulled out by the two wire removing rollers and sent into the material receiving bin.

[0015] Compared with the prior art, the anti - entanglement roller structure of the regenerated polyester fiber winding equipment of the present utility model uses two groups of anti - entanglement roller units to remove broken filaments and pulp blocks on both sides of the fiber bundle. During the removal process, the metal pressing roller is attached to the fiber bundle, and the broken filaments are scraped up by the friction between the metal pressing roller and the fiber bundle, thereby realizing the separation of the fiber bundle and the broken filaments. At the same time, when the fiber bundle passes through the metal pressing roller, it can remove static electricity from the fiber bundle, and the separated broken filaments and pulp blocks are sent into the inner side of the material receiving bin by the meshing rotation of the two wire removing rollers, ensuring the smoothness of the entire filament winding.
