Detailed Implementation
[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0012] Depend on Figure 1 and Figure 2 The present invention includes a cleaning box 1, with a water box 2 fixedly installed at the bottom of the cleaning box 1 and communicating with it. The lower part of the cleaning box 1 has a V-shaped structure. Exhaust pipes 3 are fixedly installed at the upper parts of both ends of the water box 2. Exhaust fans 4 are installed in the middle of the two exhaust pipes 3. Two gauze holes 5 are symmetrically provided on both sides of the upper part of the cleaning box 1. Several air inlets 8 are opened on the top of the cleaning box 1. Protective nets 9 are installed inside the air inlets 8. Three pairs of cleaning shafts 6 are equidistantly rotatably installed in the upper part of the interior of the cleaning box 1. The surfaces of the three pairs of cleaning shafts 6 are all covered with protective nets. The cleaning box 1 is equipped with a soft brush bristle 7. The bottom two sides of the cleaning box 1 are fitted with lint absorbent components 10. An operation port 26 is provided on one side of the cleaning box 1. The yarn can be effectively passed through the two yarn holes 5 and between the three pairs of cleaning shafts 6 through the operation port 26, so that the soft brush bristle 7 comes into contact with the yarn. A sealing plate 27 is bolted to the upper part of the operation port 26. A drain pipe 28 is installed at the bottom of the water box 2. A valve 29 is installed on the upper part of the drain pipe 28. A water inlet pipe 30 is installed on the other side of the water box 2.
[0013] Each of the two lint wet adsorption components 10 includes a pair of rotating shafts 11. Each pair of rotating shafts 11 is rotatably installed inside the cleaning box 1 and the water box 2, respectively. Both ends of the rotating shafts 11 are fixedly installed with sprockets 12. A chain 13 is installed between two adjacent sprockets 12 on each pair of rotating shafts 11. A filter screen 14 is installed between two chains 13 on each pair of rotating shafts 11. One end of the two rotating shafts 11 located inside the water box 2 extends movably through to the outside of the water box 2 and is fixedly connected to a sprocket 2 15. A chain 2 16 is installed between two sprockets 2 15. The rotating shafts 11, sprockets 12, chains 13 and filter screen 14 are all made of stainless steel, so that the two lint wet adsorption components 10 can effectively rotate and get wet, so that lint can adhere to them.
[0014] Specifically, the yarn is passed through the inside of the two yarn holes 5 and through the three pairs of cleaning shafts 6, so that the cleaning brush bristles 7 come into contact with the yarn. The cleaning shafts 6 drive the cleaning brush bristles 7 to rotate, thereby cleaning the lint on the surface of the yarn and causing the lint to disperse inside the cleaning box 1. At the same time, the two sprockets 15 and the chain 16 cause the two shafts 11 inside the water box 2 to rotate. The rotation of the two shafts 11 inside the water box 2 will drive the two filters 14 to rotate in a circle through the shafts 11, sprockets 12 and the chain 13. The rotation of the two filters 14 will pick up water from inside the water box 2, thus making the surface of the filters 14 wet. The two exhaust fans 4 are activated to draw outside air into the cleaning box 1 through the air inlet 8. The air is then drawn into the water box 2 and discharged through the exhaust pipe 3. During the air circulation, lint adheres to the surface of the filter screen 14. The rotation of the filter screen 14 causes the adhered lint to mix into the water inside the water box 2, thereby achieving effective cleaning of the lint.
[0015] A dual-shaft motor 17 is installed on one side of the cleaning box 1. One output end of the dual-shaft motor 17 is fixedly connected to the end of one of the rotating shafts 11 inside the cleaning box 1. A bevel gear 18 is fixedly installed on the other output end of the dual-shaft motor 17. A bevel gear 19, which meshes with bevel gear 18, is rotatably installed on one side of the cleaning box 1 via a connecting shaft. A bevel gear 20 is fixedly installed on the top of the connecting shaft. One end of each of the three pairs of cleaning shafts 6 extends movably through to the outside of the cleaning box 1 and is fixedly installed with a meshing gear 21. A bevel gear 22 is fixedly installed at the shaft center on one side of one of the gears 21 on each of the three pairs of cleaning shafts 6. An adjusting shaft 23 is rotatably installed on one side of the cleaning box 1. Three bevel gears 24 are fixedly installed on the surface of the adjusting shaft 23. The three bevel gears 24 mesh with the three bevel gears 22 respectively. A bevel gear 25, which meshes with bevel gear 20, is fixedly installed on one end of the adjusting shaft 23, thereby enabling transmission.
[0016] Specifically, by starting the dual-output shaft motor 17, one of the rotating shafts 11 inside the cleaning box 1 is rotated. The rotation of the rotating shaft 11 causes the two filter screens 14 to rotate in circles through the two sprockets 15 and the chain 16. At the same time, the start of the dual-output shaft motor 17 will drive the rotation of bevel gear 6 25 through bevel gear 1 18, bevel gear 2 19 and bevel gear 3 20. The rotation of bevel gear 6 25 will drive the adjustment shaft 23 and the three bevel gears 5 24 to rotate. The rotation of the three bevel gears 5 24 will drive the three bevel gears 4 22. The rotation of the three bevel gears 4 22 will cause the three cleaning shafts 6 to rotate through the three pairs of meshing gears 21, so that the cleaning brush 7 can clean the lint on the surface of the yarn.
[0017] This yarn cleaning device features a lint sweeping and wet lint adsorption treatment structure. The lint sweeping structure cleans the surface of the conveyed yarn of lint, while the wet lint adsorption treatment structure adsorbs the cleaned and scattered lint, thus effectively ensuring the cleaning effect of the yarn lint. At the same time, this yarn cleaning device has a simple structural design, is convenient and easy to use, and has stable and reliable cleaning operation. Its performance can meet the yarn cleaning needs of circular knitting machines.
