Description

Technical Field

[0001] This invention relates to the field of fiber spinning technology, and in particular to an adsorption-type filament impurity removal device. Background Technology

[0002] When producing fiber filaments through melt spinning, the molecular structure changes during high-temperature heating, and some bonds break, leading to the generation of impurities. These impurities must be removed in time to ensure the quality of the filaments; otherwise, a lot of lint will be generated in subsequent processes. The existing method is to remove impurities and gases by using a suction fan. However, for a large number of bundled filaments, the impurities will be trapped inside by the suction fan alone, resulting in an unsatisfactory impurity removal effect.

[0003] To address this, an improved technology has been proposed for an impurity removal device in nylon filament production, comprising a base plate and a suction port of a blower. This improved technology utilizes a working motor to rotate a threaded shaft, causing a threaded sleeve to move a plastic paddle along a connecting groove. As the plastic paddle moves, it separates the nylon filaments one by one, preventing a large number of nylon filaments from being bundled together and the impurities trapped within them from being sucked away by the suction port of the blower, thus improving work efficiency. However, in actual use, the movement of the plastic paddle can easily cause wear on the fiber filaments, and its actual dispersing effect is limited.

[0004] In conclusion, in order to better remove impurities from filament bundles, it is necessary to improve and optimize the structure of the filament impurity removal device. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 4 This invention provides an adsorption-type filament impurity removal device: a housing 1, a negative pressure station, and a filter box. The upper wall of the housing 1 is rotatably connected to a top cover 2 via a hinge. The upper wall of the top cover 2 and the lower wall of the housing 1 are respectively provided with adsorption devices for evacuating air from the housing 1. The adsorption devices include a first adsorption hood 3 and a second adsorption hood 8, which are respectively fixedly connected to the upper wall of the top cover 2 and the lower wall of the housing 1. The first adsorption hood 3 is used to adsorb between the first rotating shaft 5 and the second rotating shaft 6, and the second adsorption hood 8 is used to adsorb between the second rotating shaft 6 and the third rotating shaft 7. The first adsorption hood 3 and the second adsorption hood 8 are respectively connected to the filter box and the negative pressure station via a first adsorption tube 4 and a second adsorption tube 9. When the filament bundle passes through the housing 1, it is adsorbed and impurities are removed from the inside of the housing 1 through the negative pressure station via the first adsorption tube 4, the first adsorption hood 3, the second adsorption tube 9, and the second adsorption hood 8. During the adsorption process, the filament bundle is filtered by the filter box. The two adsorption processes (one top and one bottom) make the impurity removal more thorough.

[0027] A filament splitter is provided on the inner wall of the housing 1 near the left end for dispersing long filament bundles. The filament splitter includes a guide plate 15 and a multi-component filament rod 16. The guide plate 15 is fixedly connected between the inner front wall and the inner rear wall of the housing 1 and near the left end of the housing 1. The multi-component filament rod 16 is fixedly connected to the upper wall of the guide plate 15 in a front-to-back distribution. The upper end of the guide plate 15 is arc-shaped in frontal view, and the multi-component filament rod 16 is cylindrical. During the initial operation, the long filament bundle is manually separated to hang multiple single filaments between the multi-component filament rod 16 for splitting. After splitting, it is pulled backward. As long as the long filaments are not broken, there is no need to manually split them again. The arc shape and the cylindrical shape are to reduce the wear on the surface of the long filaments.

[0028] Two sets of first rotating shafts 5, second rotating shafts 6, and third rotating shafts 7 are rotatably connected to the inner wall of the housing 1 from left to right. These shafts are arranged vertically. A drive assembly for driving rotation is provided between the shafts and the housing 1. The drive assembly includes a fixed plate 10 and three motors 11. The fixed plate 10 is fixedly connected to the rear wall of the housing 1, near the lower wall. The three motors 11 are arranged horizontally and fixedly connected to the upper wall of the fixed plate 10. The three motors 11 are vertically aligned with the shafts 5, 6, and 7 respectively. The lower set of shafts 7 is connected to the three sets of motors 11 via two sets of synchronous pulleys 12 and synchronous belts 13. The two sets of first rotating shafts 5, the two sets of second rotating shafts 6, and the two sets of third rotating shafts 7 are connected via two sets of gears 14. Multiple monofilaments pulled out from the splitter pass through the two sets of first rotating shafts 5, the two sets of second rotating shafts 6, and the two sets of third rotating shafts 7, and are kept in a relaxed state beforehand. The three sets of motors 11 rotate at the same speed, so that the rotation speeds of the two sets of first rotating shafts 5, the two sets of second rotating shafts 6, and the two sets of third rotating shafts 7 are kept sequential. The pre-set relaxed state is maintained in subsequent production. The relaxed state of the monofilaments after splitting makes it easier to separate impurities.

[0029] The outer walls of one end of the two sets of first rotating shafts 5, second rotating shafts 6 and third rotating shafts 7 located inside the housing 1 are all fixedly connected with rollers 17 for conveying long filament bundles. The long filament bundles between the rollers 17 on the first rotating shaft 5 and the rollers 17 on the second rotating shaft 6, and between the rollers 17 on the second rotating shaft 6 and the rollers 17 on the third rotating shaft 7 are all in a relaxed state. All sets of rollers 17 are rubber wheels. The outer walls of the two sets of rollers 17 that are opposite each other abut against each other. Inside the housing 1, the movement of the filament bundle does not rely on the winding machine that collects the filament bundle at the rear end, but on the traction caused by the relative rotation of the two sets of rollers 17.

[0030] Working principle: During initial operation, the long filament bundle is manually separated by hanging multiple monofilaments between multiple groups of wire rods 16 for separation. After separation, the filaments are pulled backward. As long as the long filaments are not broken, manual separation is not required. The arc and cylindrical shapes are to reduce wear on the surface of the long filaments. The multiple monofilaments pulled out from the separator pass between two sets of first rotating shafts 5, two sets of second rotating shafts 6, and two sets of third rotating shafts 7, and are kept in a relaxed state beforehand. The three sets of motors 11 rotate at the same speed, so that the rotation speeds of the two sets of first rotating shafts 5, two sets of second rotating shafts 6, and two sets of third rotating shafts 7 are kept sequential. The pre-set relaxed state is maintained in subsequent production. The relaxed state of the separated monofilaments makes it easier to separate impurities. When the separated monofilaments pass through the box 1, they are adsorbed and removed from the inside of the box 1 by the negative pressure station through the first adsorption tube 4, the first adsorption hood 3, the second adsorption tube 9, and the second adsorption hood 8. During the adsorption process, the filaments are filtered by the filter box. Through two adsorption processes, one above and one below, the removal of impurities is more thorough.

[0031] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. 。
