Description

Technical Field

[0001] This utility model relates to the field of material supply device technology, and more specifically, to a fully automatic powder quantitative feeding device. Background Technology

[0002] Feeding devices are widely used in many industrial production and material handling fields. Their main function is to supply materials to the corresponding equipment or production process in a uniform, quantitative, continuous or intermittent manner according to the set requirements. Based on their different feeding principles, they can be roughly divided into two types: gravity feeding and mechanical power feeding. Gravity feeding is only suitable for some liquids, granules or powders with good flowability, while mechanical power feeding can be used in various occasions.

[0003] When operators feed powdered materials into processing equipment, they often use a quantitative feeding device to accurately control the amount of material fed each time. However, in actual use, although the existing quantitative feeding devices have basic quantitative functions, they generally use a quantitative container for quantitative feeding. The volume of the quantitative container is usually fixed, which makes it impossible for operators to adjust the amount of material fed. Therefore, it is necessary to improve the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 7 As shown, this utility model provides a fully automatic powder quantitative feeding device, including a feeding box 1. A hopper 2 is fixedly connected to the right side of the upper surface of the feeding box 1. A feeding block 3 located below the hopper 2 is movably connected to the inner surface of the feeding box 1. A movable block 4 is movably connected to the right side of the inner surface of the feeding block 3. The right end of the movable block 4 passes through the feeding block 3 and extends to the right side of the feeding block 3. A cylinder 5 located to the right side of the feeding block 3 is fixedly connected to the outer surface of the movable block 4. An L-shaped plate 6 is fixedly connected to the bottom end of the right surface of the feeding block 3. Movable shafts 7 are movably sleeved on both the front and rear sides of the lower surface of the L-shaped plate 6. There are two movable shafts 7. The top ends of the two movable shafts 7 pass through the L-shaped plate 6 and extend above the fixed block 10. Gears 8 are fixedly sleeved on the outer surfaces of the two movable shafts 7. A drive rod is fixedly sleeved on the upper side of the outer surfaces of the two movable shafts 7. 9. The inner surface of the driving rod 9 is movably connected to the cylinder 5. Fixing blocks 10 are fixedly connected to both the front and rear sides of the outer surface of the L-shaped plate 6. A motor 11 is fixedly installed on the rear surface of the fixing block 10. A double-threaded screw 12 is fixedly sleeved at the other end of the output shaft of the motor 11. The front end of the double-threaded screw 12 passes through the fixing block 10 and extends to the front side of the fixing block 10. A toothed block 13 is threadedly sleeved on the outer surface of the double-threaded screw 12. The outer surface of the toothed block 13 meshes with the outer surface of the gear 8. When the operator starts the motor 11, the double-threaded screw 12 will start to rotate and cause the two toothed blocks 13 to start to move towards each other. During this process, the two movable shafts 7 will start to rotate under the drive of the toothed blocks 13. At the same time, the inner surface of the driving rod 9 will drive the cylinder 5, causing the cylinder 5 and the moving block 4 to start to move to the left.

[0024] The right surface of the feeding block 3 is fixedly connected to a sealing plate 31. The right end of the sealing plate 31 passes through the L-shaped plate 6 and the feeding box 1 and extends to the right side of the feeding box 1. The upper surface of the sealing plate 31 is movably connected to the top of the inner surface of the feeding box 1. The upper surface of the toothed block 13 is movably connected to a limiting block 14. The bottom end of the limiting block 14 is fixedly connected to the outer surface of the L-shaped plate 6. A feeding port 15 is opened on the left side of the bottom end of the inner surface of the feeding box 1. A limiting plate 16 located on the left side of the feeding port 15 is fixedly connected to the bottom end of the inner surface of the feeding box 1. The size of the feeding port 15 is the same as the size of the inner surface of the feeding block 3. The limiting plate 16 plays a positioning role for the entire feeding block 3. When the left surface of the feeding block 3 contacts the right surface of the limiting plate 16, the bottom end of the feeding block 3 will be aligned with the feeding port 15.

[0025] The second motor 17 is fixedly installed on the rear side of the left surface of the feeding box 1. The other end of the output shaft of the second motor 17 is fixedly sleeved with a single threaded screw 18 located above the first motor 11. The right end of the single threaded screw 18 passes through the feeding box 1 and the feeding block 3 in sequence and extends to the right surface of the feeding box 1. The outer surface of the single threaded screw 18 and the inner surface of the feeding block 3 are threadedly sleeved. When the operator starts the second motor 17, the single threaded screw 18 will start to rotate. At this time, the feeding block 3 will be driven by the rotation of the single threaded screw 18 and will start to move left and right along the inner surface of the feeding box 1.

[0026] Among them, a limiting rod 19 is fixedly connected to the front side of the left surface of the feeding box 1. The right end of the limiting rod 19 passes through the feeding box 1 and the feeding block 3 in sequence and extends to the right surface of the feeding box 1. The outer surface of the limiting rod 19 and the inner surface of the feeding block 3 are movably sleeved. When the single threaded screw 18 rotates and the feeding block 3 starts to move left and right, the design of the limiting rod 19 will restrict the movement direction of the feeding block 3, thereby ensuring that the feeding block 3 will not rotate under the drive of the single threaded screw 18.

[0027] The upper surface of the feeding box 1 is movably connected to a pusher plate 20 located directly above the feeding port 15. The bottom end of the pusher plate 20 penetrates the feeding box 1 and extends into the interior of the feeding box 1. A connecting post 21 is fixedly connected to the upper surface of the pusher plate 20. A top plate 22 is fixedly connected to the upper surface of the connecting post 21. Limiting posts 23 located on the front and rear sides of the pusher plate 20 are fixedly connected to the upper surface of the feeding box 1. The top end of the limiting post 23 penetrates the top plate 22 and extends above the top plate 22. The outer surface of the limiting post 23 and the inner surface of the top plate 22 are movably sleeved. The size of the pusher plate 20 is the same as the inner surface size of the feeding port 15. When the feeding block 3 is aligned with the feeding port 15, the downward movement of the pusher plate 20 will scrape off the powder adhering to the inner wall of the feeding block 3 and the moving block 4. The limiting posts 23 restrict the overall movement direction of the pusher plate 20.

[0028] The upper surface of the feeding box 1 is fixedly equipped with a No. 3 motor 24 located on the left side of the pusher plate 20. The other end of the output shaft of the No. 3 motor 24 is fixedly sleeved with a round shaft 25. The outer surface of the round shaft 25 is fixedly sleeved with a drive rod 26. The other end of the drive rod 26 is hinged with a driven rod 27. The other end of the driven rod 27 is hinged to the left surface of the top plate 22. When the operator starts the No. 3 motor 24, the round shaft 25 and the drive rod 26 will start to rotate. At this time, the other end of the drive rod 26 will drive the driven rod 27, causing the driven rod 27 to start to rotate. At the same time, the other end of the driven rod 27 will drive the top plate 22, causing the top plate 22 to move downward as a whole.

[0029] The front surface of the feeding block 3 is fixedly connected to a reference block 28, and the front surface of the moving block 4 is fixedly connected to a scale block 29. The front ends of both the reference block 28 and the scale block 29 penetrate the feeding box 1 and extend to the outside of the feeding box 1. The left surface of the scale block 29 is fixedly connected to a connecting block 30 located in front of the feeding box 1. The left end of the connecting block 30 penetrates the reference block 28 and extends to the left side of the reference block 28. The outer surface of the connecting block 30 and the inner surface of the reference block 28 are movably connected. The outer surface of the connecting block 30 is marked with a scale, and the operator can read the scale exposed on the left side of the reference block 28 to determine the maximum volume of the cavity formed by the feeding box 1, the feeding block 3, and the moving block 4 at the current moment.

[0030] Working principle and usage process of this utility model:

[0031] First, the operator starts motor 11. As motor 11 runs, the double-threaded screw 12 begins to rotate, causing the two gear blocks 13 to move towards each other under the limit of the limit block 14. Since the gear blocks 13 and gears 8 mesh with each other, the rotation of the gear blocks 13 will cause the two gears 8 to rotate in opposite directions. During this process, the inner surfaces of the two drive rods 9 will drive the cylinder 5, causing the cylinder 5 and the moving block 4 to move to the left. As the moving block 4 moves, the volume of the cavity formed by the feeding box 1, the feeding block 3, and the moving block 4 will gradually decrease until the scale of the connecting block 30 exposed on the left side of the reference block 28 meets the operator's feeding needs.

[0032] The operator then feeds the material into the hopper 2. The powder material inside hopper 2 falls under gravity into the cavity formed by the feeding box 1, feeding block 3, and moving block 4. The operator then starts motor 17. As motor 17 operates, the single-threaded screw 18 begins to rotate, causing feeding block 3 to move to the left. When feeding block 3 contacts the limit plate 16, the material between feeding block 3 and moving block 4 falls under the feeding box 1 under gravity. The operator then starts motor 3 24. As motor 3 24 runs, the circular shaft 25 and the drive rod 26 will start to rotate. At this time, the other end of the drive rod 26 will drive the driven rod 27, causing the driven rod 27 to start rotating. At the same time, the other end of the driven rod 27 will drive the top plate 22, causing the top plate 22, the connecting column 21 and the pusher plate 20 to move downward. Finally, the pusher plate 20 will scrape off the powder material attached to the inner wall of the feeding block 3 and the moving block 4, thereby completing the quantitative feeding of the powder material.
