Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, and in particular to a feeding structure for a screw feeder. Background Technology

[0002] Screw feeders are a type of continuous conveying equipment widely used in industrial production, primarily for the uniform feeding of powdery, granular, and small lump materials. Their working principle involves the rotation of spiral blades, which propels the material forward along the spiral grooves, thus achieving continuous material conveying. Due to their simple structure, convenient operation, and good sealing performance, screw feeders are widely used in industries such as chemical, metallurgical, building materials, and food processing.

[0003] However, existing screw feeders still have certain defects. For example, the screw blades are usually wrapped inside the feeding pipe, which makes it difficult for traditional cleaning and maintenance methods to directly contact the blade surface. As a result, after the equipment has been running for a period of time, material residues tend to accumulate on the blades, affecting the conveying efficiency. Secondly, there is usually no filter component installed inside the feed hopper, which allows impurities in the material to enter the feeding pipe, thereby affecting the quality of the subsequent processed products. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding structure for a screw feeder that allows the pipe cover to be opened, making it convenient for workers to clean and maintain the screw blades, thereby improving the performance.

The outer surface of the connecting shaft 16 is rotatably connected to a U-shaped frame 17. The outer surface of the feeding pipe 1 is fixedly connected to a support seat 26. The outer surface of the support seat 26 is provided with a through hole 27 to facilitate the installation of this device on the equipment. The outer surface of the buckle seat 10 is provided with a buckle groove 28. The inner surface of the buckle groove 28 is adapted to the U-shaped frame 17 to facilitate the closing of the pipe cover 5. The outer surface of the limiting block 13 is rotatably connected to the fixed box 11 to limit the rotation of the threaded rod 12. The outer surface of the internal hexagonal sleeve 14 is rotatably connected to the fixed box 11. The outer surface of the connecting slider 15 is slidably connected to the fixed box 11 to limit the movement of the connecting slider 15. The first motor is electrically connected to an external power source.

[0030] A second motor 18 is fixedly connected to the right surface of the feed hopper 7. A rotating shaft 19 is fixedly connected to the output end of the second motor 18. A cam block 20 is fixedly connected to the outer surface of the rotating shaft 19. A limiting groove 21 is provided on the inner surface of the feed hopper 7. A sliding rod 22 is fixedly connected to the inner surface of the limiting groove 21. A spring 23 is provided on the outer surface of the sliding rod 22. A moving block 24 is slidably connected to the outer surface of the sliding rod 22. A filter screen 25 is fixedly connected to the outer surface of the moving block 24. The outer surface of the rotating shaft 19 is rotatably connected to the feed hopper 7. There are two cam blocks 20, which are symmetrically distributed. The upper surface of the filter screen 25 is in contact with the cam blocks 20 to facilitate the shaking of the filter screen 25. The inner surface of the limiting groove 21 is adapted to the moving block 24. The outer surface of the filter screen 25 is slidably connected to the feed hopper 7 to limit the movement of the filter screen 25. The second motor 18 is electrically connected to an external power source.

[0031] Working principle: During operation, material is poured into the feed hopper 7, and then the second motor 18 and the first motor 8 are started. Under the action of the second motor 18, the rotating shaft 19 drives the cam block 20 to rotate, thereby repeatedly squeezing the filter screen 25 under the action of the spring 23. Finally, under the action of the moving block 24, the filter screen 25 is shaken up and down along the slide rod 22. At this time, the material poured into the feed hopper 7 will be filtered by the filter screen 25 and then sent into the feed pipe 1. Then, under the action of the first motor 8, the falling material is transported to the discharge pipe 6 by the spiral blades 9 for discharge. When the spiral blades 9 need to be cleaned and maintained, simply use the hexagonal handle to turn the internal hexagonal sleeve 14, driving the threaded rod 12 to the limit block 13. Under the action of the position, the connecting slider 15 moves upward, which can drive the U-shaped frame 17 to disengage from the inside of the slot 28. Then, the U-shaped frame 17 is flipped with the connecting shaft 16 as the axis, which can release the restriction on the pipe cover 5. Subsequently, with the cooperation of the fixed seat 2 and the flipping seat 4, the pipe cover 5 is flipped with the fixed column 3 as the axis, which can expose the spiral blade 9 inside the feeding pipe 1 for cleaning and maintenance. After cleaning, the pipe cover 5 is flipped again with the fixed column 3 as the axis to close it with the feeding pipe 1. Then the U-shaped frame 17 is flipped. When the U-shaped frame 17 corresponds to the slot 28, the internal hexagonal sleeve 14 is rotated in the opposite direction to make the U-shaped frame 17 snap into the slot 28, thereby completing the closure of the feeding pipe 1 and the pipe cover 5 for material conveying.
