Abstract
Description
Technical Field
[0001] This utility model relates to the field of quantitative feeding equipment technology, and in particular to a powder quantitative feeding device. Background Technology
[0002] Currently, many industrial production processes require the use of powder materials, such as flour and pharmaceutical powder. These powder materials are typically fed into the production equipment via a feeding device.
[0003] Some existing quantitative conveying devices use a housing with multiple cavities to continuously convey powder in a fixed quantity by rotating. However, when the housing rotates, the powder gets stuck in the contact area between the housing and the device body, generating significant friction. This causes a lot of electrical energy to be converted into heat during conveying, which can easily damage the device. At the same time, the friction accelerates the wear and tear of the device, resulting in poor performance. Utility Model Content
[0004] This utility model discloses a powder quantitative feeding device, which aims to solve the technical problem that existing devices cause friction when conveying powder.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A powder metering feeding device includes a powder shell, a support plate fixedly connected to the lower end of the powder shell, a drive motor fixedly connected to the lower end of the support plate, a reciprocating screw fixedly connected to the output end of the drive motor, a moving plate meshing with the wall of the reciprocating screw, a sliding connection between the outer side of the moving plate and the lower right side of the powder shell, a rectangular plate slidably connected to the upper end of the moving plate, a first spring fixedly connected to the lower end of the rectangular plate, a limit plate fixedly connected to the upper end of the right inner wall of the powder shell, and a conveying shell inclinedly arranged on the right side of the powder shell.
[0007] Preferably, a support frame is fixedly connected to the lower end of the powder shell;
[0008] Preferably, the lower inner wall of the powder shell is inclined, and a vibration motor is provided inside the powder shell;
[0009] Preferably, a rod is slidably connected to the left side of the powder shell, a push plate is fixedly connected to the right side of the rod, and a second spring is sleeved on the rod wall;
[0010] Preferably, a baffle is fixedly connected to the left side of the limiting plate;
[0011] Preferably, a cover plate is rotatably connected to the upper end of the powder shell.
[0012] As can be seen from the above, the advantages of the powder quantitative feeding device provided by this utility model are: during operation, by continuously moving the upper end of the moving plate, the material can be quantitatively fed into the inside of the conveying shell. This structure will not generate excessive friction between the material and the powder, and the conveying operation can be carried out stably. Attached Figure Description

[0020] Reference Figure 1-3 A powder metering feeding device includes a powder shell 2, with a cover plate 4 rotatably connected to the upper end of the powder shell 2. Opening the cover plate 4 allows the powder to be fed into the powder shell 2. A support frame 1 is fixedly connected to the lower end of the powder shell 2 for support. A support plate 5 is fixedly connected to the lower end of the powder shell 2, and a drive motor 6 is fixedly connected to the lower end of the support plate 5. A reciprocating screw 13 is fixedly connected to the output end of the drive motor 6, enabling the drive motor 6 to drive the reciprocating screw 13 to rotate. A moving plate 7 is engaged with the rod wall of the reciprocating screw 13. The rotation of the reciprocating screw 13 causes the moving plate 7 to continuously rotate. The moving plate 7 moves up and down, and its outer side is slidably connected to the lower right side of the powder shell 2. A rectangular plate 15 is slidably connected to the upper end of the moving plate 7. The movement of the moving plate 7 drives the rectangular plate 15 to move. A first spring 16 is fixedly connected to the lower end of the rectangular plate 15. The first spring 16 provides an upward supporting force to the rectangular plate 15. A limiting plate 12 is fixedly connected to the upper end of the right inner wall of the powder shell 2. The limiting plate 12 can limit the upward movement of the rectangular plate 15. A baffle 11 is fixedly connected to the left side of the limiting plate 12. The limiting plate 12 can prevent the powder from moving to the left. A conveying shell 3 is inclinedly arranged on the right side of the powder shell 2.
[0021] During operation, the powder to be conveyed is poured into the powder housing 2. At this time, the drive motor 6 works, driving the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 causes the moving plate 7 to move up and down continuously. When the moving plate 7 is at the lower end, the powder inside the powder housing 2 enters the upper end of the moving plate 7. The rectangular plate 15 limits the powder entering the upper end of the powder housing 2. The moving plate 7 moves upward, causing the rectangular plate 15 and the powder at the upper end to move upward together, and the amount of powder is constant. When the rectangular plate 15 contacts the lower end of the limiting plate 12, When the rectangular plate 15 can no longer move up and down, it moves downward relative to the moving plate 7, compressing the first spring 16. This allows the powder at the upper end of the moving plate 7 to pass through the limiting plate 12. The upper end of the moving plate 7 is inclined, which has a certain guiding effect, allowing the powder to enter the interior of the conveying shell 3 for conveying. In this way, during operation, by continuously moving the upper end of the moving plate 7, the material can be quantitatively conveyed into the interior of the conveying shell 3. This structure will not generate excessive friction between the material and the powder, and can stably carry out the conveying operation.
[0022] Reference Figure 2 The lower inner wall of the powder shell 2 is inclined, and the powder shell 2 is equipped with a vibration motor 14, which can make the lower end of the powder shell 2 vibrate, so that the powder can move to the right and ensure the stability of material conveying.
[0023] Reference Figure 2 A rod 10 is slidably connected to the left side of the powder shell 2, and a push plate 8 is fixedly connected to the right side of the rod 10. A second spring 9 is sleeved on the rod wall of the rod 10. By pushing the rod 10, the rod 10 drives the push plate 8 to move. The push plate 8 moves at the lower end of the powder shell 2, pushing the powder to move. This ensures that the powder inside the powder shell 2 is discharged as much as possible.
[0024] Working principle: During operation, the powder to be conveyed is poured into the powder shell 2. At this time, the drive motor 6 works, driving the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 causes the moving plate 7 to move up and down continuously. When the moving plate 7 is at the lower end, the powder inside the powder shell 2 enters the upper end of the moving plate 7. The rectangular plate 15 limits the powder entering the upper end of the powder shell 2. The moving plate 7 moves upward, causing the rectangular plate 15 and the powder at the upper end to move upward together, and the amount of powder is constant. When the rectangular plate 15 contacts the lower end of the limiting plate 12... When the rectangular plate 15 can no longer move up and down, it moves downward relative to the moving plate 7, compressing the first spring 16. This allows the powder at the upper end of the moving plate 7 to pass through the limiting plate 12. The upper end of the moving plate 7 is inclined, which has a guiding effect, allowing the powder to enter the interior of the conveying shell 3 for conveying. In this way, during operation, by continuously moving the upper end of the moving plate 7, the material can be quantitatively conveyed into the interior of the conveying shell 3. This structure will not generate excessive friction between the material and the powder, and can stably carry out the conveying operation.
