Description

Technical Field

[0001] This invention relates to the field of cleaning devices, specifically to an automatic cleaning device for a mobile glue-adding hopper. Background Technology

[0002] Wrapping machines require adhesive impregnation during yarn winding. Each machine is equipped with one or more adhesive tanks. To facilitate adhesive addition to each tank, a movable adhesive-adding trolley is mounted on a long track beam. The trolley moves the adhesive hopper along the track beam to add adhesive to each tank. Since the adhesive residue adheres to the inner wall of the hopper after addition and easily dries, affecting its usability, the inner wall of the hopper needs to be scraped and cleaned periodically after addition. Because the track beam of the adhesive-adding trolley is tens or even hundreds of meters long, the trolley's travel distance is significant. If the cleaning device is directly fixed to the trolley, it will move with the trolley, and the cleaning fluid supply for the cleaning device is fixed, making it impossible to... As the adhesive is moved, acetone or alcohol is typically used for cleaning. Acetone and alcohol are highly flammable and volatile, posing a significant danger if they move with the adhesive trolley. Therefore, existing technology fixes the cleaning device to a track beam. The cleaning device includes a lifting mechanism and an electric cleaning mechanism. When the adhesive trolley moves the adhesive hopper directly under the cleaning device, the lifting mechanism lowers the electric cleaning mechanism into the hopper to scrape the inner wall. After scraping, the lifting mechanism raises the electric cleaning mechanism, and then the adhesive trolley moves the hopper away. However, as the electric cleaning mechanism rises and the cleaned hopper leaves its direct line of sight, the cleaning fluid (acetone) attached to the electric cleaning mechanism drips into the workshop, causing contamination.

[0038] Working principle of the present invention: When the glue bucket 3 needs to be cleaned, the glue adding trolley 2 drives the glue bucket 3 to move on the track beam 1, and the glue bucket drives the cleaning component to move synchronously. When the driving shaft docking pipe 35 is directly below the driving shaft 18, the glue adding trolley 2 stops moving, and the servo motor 10 is started to drive the gear 11 to rotate. The gear 11 drives the rack 15 to descend. The rack 15 drives the second side plate 13, the linear guide rail 15 and the second bottom plate 12 to descend. The linear guide rail 15 slides down on the guide rail slider 9. The second bottom plate 12 drives the motor 16, the speed reducer 17, the fixing seat 20, the rotary joint 21 and the driving shaft 18 on its upper part to descend. During this process, the motor 16 drives the output shaft of the speed reducer 17 to rotate. The speed reducer 17 drives the driving shaft 18 to rotate. The driving shaft 18 that rotates while descending docks with the driving shaft docking pipe 35. The driving shaft docking pipe 35 is inserted into the square docking hole 22. The driving shaft sealing shaft guide pipe 25 is inserted into the driving shaft docking pipe 35. During this period, when the driving shaft docking pipe 35 is inserted into the square docking hole 22, the outer chamfer 36 of the docking pipe first docks with the outer chamfer 23 of the rotating docking hole. When the driving shaft docking pipe 35 is inserted into the square docking hole 22, the 4 outer chamfers 36 of the docking pipe are inserted into the 4 inner chamfers 24 of the docking hole. In this way, the driving shaft 18 and the driving shaft docking pipe 35 form a limit connection. When the driving shaft 18 rotates, it drives the driving shaft docking pipe 35 to rotate. At the same time, when the driving shaft sealing shaft guide pipe 25 is inserted into the driving shaft docking pipe 35, the rotating outer chamfer 26 of the guide pipe is inserted into the inner chamfer 37 of the docking pipe. The above connection principle is that the inclined surface of the chamfer forms a "wedge-shaped guiding surface". Through the rotation deviation correction at one end of the docking end, it avoids the direct collision and jamming of the corners. When the rotating square docking hole 22 is sleeved on the driving shaft docking pipe 35, the rotating inner chamfer 24 of the docking hole is finally sleeved on the outer chamfer 36 of the docking pipe, forming a "hui" character shape, so that the driving shaft 18 can drive the driving shaft docking pipe 35 to rotate. The driving shaft docking pipe 35 drives the bearing inner lining sleeve fixing pipe 34, the bearing inner lining sleeve fixing pipe 34 drives the bearing inner lining sleeve 33 to rotate on the bearing 32. The bearing inner lining sleeve fixing pipe 34 drives the horizontal diversion pipe 38 to rotate. The horizontal diversion pipe 38 drives the L-shaped cleaning pipe 39. The L-shaped cleaning pipe 39 drives the L-shaped fixing plate 40 and the L-shaped scraping plate 42 to rotate. The cleaning liquid enters the driving shaft sealing shaft guide pipe 25 through the rotary joint 21, enters the driving shaft docking pipe 35 from the driving shaft sealing guide pipe 25, then enters the bearing inner lining sleeve fixing pipe 34, then enters the horizontal diversion pipe 38, and then enters the L-shaped cleaning pipe 39, and is sprayed from the spray hole 41 to the inner wall of the glue bucket 3. Cooperating with the rotating L-shaped scraping plate 42, the glue liquid on the inner wall of the glue bucket 3 is cleaned and scraped off. After the cleaning is completed, the motor 16 is turned off, and the supply of the cleaning liquid is stopped. The servo motor 10 drives the driving shaft 18 to rise, and the driving shaft 18 and the driving shaft docking pipe 35 are automatically separated. The glue adding trolley 2 drives the glue bucket 3 to leave the lower side of the driving shaft 18.
