Description

Technical Field

[0001] This utility model relates to the field of cloth wheel processing technology, and in particular to a scraper for applying slurry to cloth wheels. Background Technology

[0002] When making fabric wheels, a layer of adhesive paste needs to be applied to the fabric to improve the bonding effect between the fabric pieces after winding. A common method for applying adhesive paste is to directly pass the moving fabric through the adhesive paste. However, as the fabric moves, the adhesive paste will drip onto other areas, and it is also inconvenient to control the thickness of the paste application. After winding, the fabric roll is prone to having an elliptical structure or a structure with raised parts. Utility Model Content

[0003] This utility model provides a scraper for applying slurry using a cloth wheel, which overcomes the shortcomings of the prior art and solves the problems existing in slurry coating, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A scraper for applying slurry using a cloth wheel includes a transversely arranged pipe with a discharge port. A guide tongue is welded to the discharge port, and the root of the guide tongue is tangent to the outer circumference of the pipe. An inlet pipe is welded upward to the outer circumference of the pipe, and a flange is provided at the upper end of the inlet pipe. End rings are welded to both ends of the pipe, and end caps are fixed to the end rings by bolts. A threaded sleeve is welded to the outer wall of the end cap, and a screw rod is threadedly connected inside the threaded sleeve. A turntable is fixed to the outer end of the screw rod by a pin, and an inner disc is welded to the inner end of the screw rod. An outer ring is fitted around the outer circumference of the inner disc, and a constraint ring is welded to the end of the outer ring. The constraint ring is fitted onto the screw rod, and a movable disc is fixed to the constraint ring by screws. The movable disc moves within the pipe.

[0005] Furthermore, a sealing ring is provided between the end cap and the end ring.

[0006] Furthermore, an outer circumferential ring is welded to the outer end of the moving disk, and the outer circumference of the outer circumference abuts against the inner circumference of the tube body.

[0007] Furthermore, a scraper ring is welded to the inner end of the moving disk, and the inner end of the scraper ring has a blade-shaped structure.

[0008] Furthermore, a collection hopper with a V-shaped cross-section is provided directly below the discharge port. End plates are welded to both ends of the collection hopper, and connecting plates are welded to the outer walls of the end plates. A strip hole is opened on the connecting plate, and a connecting screw is inserted into the strip hole. The connecting screw is threaded to the end cap, and the inner end of the end cap on the connecting screw abuts against the outer wall of the connecting plate.

[0009] The advantages of the above technical solution are: This utility model has a discharge port with a certain opening size, and during the coating process, the slurry is guided by the guide tongue, so that the slurry is uniformly discharged to be evenly coated on the upper side of the cloth.

[0010] Secondly, it is convenient to adjust the width of the discharge port according to the width of the cloth, so as to adapt to the coating operation of slurry on cloths of different widths. Furthermore, the position of the moving disc can be adjusted, and the scraper ring on it can be used to scrape and clean the inner wall of the tube.

[0011] Thirdly, after coating is completed, the slurry can be collected through a collection hopper to prevent it from flowing out and causing waste. Attached Figure Description

[0017] like Figures 1-4 As shown, a scraper for applying slurry using a cloth wheel includes a transversely arranged pipe body 1 with a discharge port 22. A guide tongue 23 is welded to the discharge port 22, and the root of the guide tongue 23 is tangent to the outer periphery of the pipe body 1. An inlet pipe 10 is welded upwards to the outer periphery of the pipe body 1. A flange 11 is provided at the upper end of the inlet pipe 10. End rings 12 are welded to both ends of the pipe body 1, and end caps 13 are fixed to the end rings 12 by bolts. The end caps 13 are connected to the end rings 12. A sealing ring is provided. A threaded sleeve 14 is welded to the outer wall of the end cap 13. A lead screw 15 is threadedly connected inside the threaded sleeve 14. A turntable 16 is fixed to the outer end of the lead screw 15 by a pin. An inner disc 25 is welded to the inner end of the lead screw 15. An outer ring 26 is fitted around the outer circumference of the inner disc 25. A constraint ring 27 is welded to the end of the outer ring 26. The constraint ring 27 is fitted onto the lead screw 15 and a movable disc 28 is fixed to the constraint ring 27 by screws. The movable disc 28 moves within the pipe body 1. An outer circumferential ring 29 is welded to the outer end of the movable disc 28, and the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the outer circumference of the inner circumference of the outer circumference of the pipe body 1. A scraper ring 30 is welded to the inner end of the movable disc 28. The inner end of the scraper ring 30 has a blade-shaped structure.

[0018] A collection hopper 20 with a V-shaped cross-section is provided directly below the discharge port 22. End plates 21 are welded to both ends of the collection hopper 20. A connecting plate 18 is welded to the outer wall of the end plate 21. A strip hole 19 is provided on the connecting plate 18. A connecting screw 17 passes through the strip hole 19. The connecting screw 17 is threaded to the end cap 13. The inner end of the end cap on the connecting screw 17 abuts against the outer wall of the connecting plate 18.

[0019] In this embodiment, the tube 1 is fixed to the mounting bracket in a horizontal arrangement, while the cloth passes underneath it. In addition, the feed pipe 10 is connected to the slurry supply tank through a hose. Furthermore, during the coating process, the cloth moves along its length.

[0020] Preparations before operation: First, adjust the position of the moving disc 28 inside the tube 1 according to the width of the cloth. During adjustment, the screw 15 is rotated by the turntable 16. When it rotates, it will drive the moving disc 28 to move. During the movement, the scraper ring 30 on it scrapes off the slurry on the inner wall of the tube 1 to prevent the slurry residue from blocking the movement of the moving disc 28.

[0021] Secondly, loosen the connecting screw 17 and rotate the collection hopper 20 to one side to prevent the presence of the collection hopper 20 from affecting the coating of the slurry and the passage of the cloth. After rotation, fix the collection hopper 20 again by tightening the connecting screw 17. Of course, when rotating, the slurry in the collection hopper 20 can be cleaned first before rotating.

[0022] During the slurry application process, the fluid slurry is injected into the pipe 1, resulting in a certain amount of slurry inside the pipe 1. The slurry then flows through the outlet 22 and along the guide tongue 23 to the upper side of the cloth. As the cloth passes through the guide tongue 23, its lower end scrapes the slurry evenly, thus ensuring the uniformity of the slurry thickness after coating.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
