Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vacuum feeding technology, and specifically relates to a vacuum feeding machine. Background Technology
[0002] A vacuum feeder, also known as a vacuum conveyor, is a dust-free, closed-loop pipeline conveying device that uses the suction force generated by a vacuum to transport granular and powdery materials. The vacuum feeder utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipeline, which in turn moves the powdery material, thus completing the powder conveying process. Existing vacuum feeders typically use butterfly valves for quantitative dispensing during the feeding process. However, due to the special nature of powders, they can stick to the tank wall during dispensing, leading to uneven dispensing.
[0003] In view of this, in order to solve the above problems, this utility model proposes a vacuum feeder that avoids powder sticking to the wall of the storage tank by vibration, and ensures uniform powder distribution each time by vibrating the material during dispensing. Summary of the Invention
[0004] This utility model provides a vacuum feeder that can ensure uniform powder distribution during filling by vibrating the material. Vibration also prevents powder from sticking to the walls of the storage tank. The specific solution is as follows:
[0005] A vacuum feeder includes a frame and a storage tank mounted on the frame. The top of the storage tank is connected to the vacuum feeder body. One side of the vacuum feeder body is connected to a crushing and feeding pipe via a powder feeding pipe. A cylindrical dispensing chamber is connected to the discharge port at the bottom of the storage tank. The dispensing chamber is horizontally positioned. A feeding trough communicating with the discharge port is opened on the upper side of the dispensing chamber. A discharge pipe is connected to the lower side of the dispensing chamber. A hollow rotating shaft is horizontally connected between the two ends of the dispensing chamber. One end of the rotating shaft penetrates the side wall of the dispensing chamber and extends outward. The rotating shaft is driven to rotate by a motor located outside the dispensing chamber. Multiple partitions are evenly spaced around the rotating shaft. The opposite sides of two connected partitions are flush with the two sides of the feeding trough. Two first bearings are spaced apart on the inner wall of the rotating shaft. A vibrating rod is connected between the two first bearings. The vibrating rod, with its end away from the motor, penetrates the wall of the dispensing chamber and extends outward.
[0006] Furthermore, a fixing block is provided on the side of the material distribution chamber away from the motor. The fixing block is detachably mounted on the material distribution chamber by screws, and the end of the vibrating rod on the outside of the material distribution chamber is fixedly connected to the fixing block.
[0007] Furthermore, a vibrator is provided on the outside of the storage tank.
[0008] Furthermore, a control panel is provided on one side of the frame, and the motor, vibrator, vibrator and vacuum feeder body are electrically connected to the control panel.
[0009] Furthermore, the two ends of the material distribution chamber are respectively inlaid with second bearings, and the two ends of the rotating shaft pass through the two second bearings respectively.
[0010] Furthermore, the powder delivery pipe is a detachable flexible hose structure.
[0011] The beneficial effects of this utility model are:
[0012] This utility model discloses a vacuum feeding machine. It features a hollow rotating shaft, a vibrating rod inside, multiple partitions mounted on it, and a motor driving the rotating shaft. When the vibrating rod is energized, it vibrates the dispensing area formed by the partitions, uniformly distributing the powder. The motor's rotation drives the rotating shaft, discharging the powder between the partitions through the discharge pipe, thus ensuring consistent powder dispensing volume each time. Furthermore, a vibrator mounted on the outside of the storage tank dislodges powder adhering to the inner wall of the tank, collecting it into the dispensing chamber, further guaranteeing uniform dispensing volume.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] See Figure 1-5A vacuum feeder includes a frame 1 and a storage tank 2 mounted on the frame 1. The storage tank 2 has an inverted conical structure. The top of the storage tank 2 is connected to the vacuum feeder body 3, which is a prior art structure. One side of the vacuum feeder body 3 is connected to a powder feeding pipe 4 and a crushing and discharging pipe 5, both of which are flexible hoses. A cylindrical distributing chamber 6 is connected to the discharge port at the bottom of the storage tank 2. The distributing chamber 6 is horizontally positioned. A feed trough 7 communicating with the discharge port is opened on the upper side of the distributing chamber 6. A discharge pipe 8 is connected to the lower side of the distributing chamber 6. A hollow rotating shaft 9 is horizontally connected between the two ends of the distributing chamber 6. One end of the rotating shaft 9... The rotating shaft 9 extends outward from the side wall of the material distribution chamber 6. It is driven to rotate by a motor 10 located outside the material distribution chamber 6. The rotating shaft 9 is evenly spaced around the circumference of multiple partitions 11. The opposite sides of two connected partitions 11 can be flush with the two sides of the feed trough 7. The ends of the multiple partitions 11 are in close contact with the inner wall of the material distribution chamber 6 during rotation to avoid material leakage. Two first bearings 12 are spaced apart on the inner wall of the rotating shaft 9. The two first bearings 12 are embedded in the inner wall of the cavity of the rotating shaft 9. A vibrating rod 13 is connected between the two first bearings 12. The outer diameter of the vibrating rod 13 is in contact with the inner diameter of the rotating shaft 9 to ensure its vibration force. The end of the vibrating rod 13 away from the motor 10 extends outward from the wall of the material distribution chamber 6.
[0021] A fixing block 14 is provided on the side of the dispensing chamber 6 away from the motor 10. The fixing block 14 is detachably mounted on the dispensing chamber 6 by screws. The end of the vibrating rod 13 on the outside of the dispensing chamber 6 is fixedly connected to the fixing block 14. The fixing block 14 is provided to fix the end of the vibrating rod 13 to prevent the connecting wire of the vibrating rod 13 from spinning and getting tangled during the rotation of the shaft 9.
[0022] A vibrator 15 is provided on the outside of the storage tank 2. The vibrator 15 can shake the powder adhering to the inner wall of the storage tank 2 and collect it into the distribution chamber 6.
[0023] A control panel 16 is provided on one side of the frame 1. The motor 10, vibrator 13, vibrator 15 and vacuum feeder body 3 are electrically connected to the control panel 16 respectively, which can realize the purpose of automatic dispensing.
[0024] The material distribution chamber 6 has two second bearings embedded at both ends, and the two ends of the rotating shaft 9 pass through the two second bearings respectively. The second bearings are set to reduce resistance during the rotation of the rotating shaft 9.
[0025] The preferred powder delivery pipe 4 is a detachable connecting hose structure.
[0026] The working principle of this utility model is as follows: First, the circuit control switches of the vibrator 13, vibrator 15, and vacuum feeder body 3 are activated simultaneously to make them work. The vacuum feeder body 3 is activated to form a vacuum negative pressure, which sucks the powder through the powder feeding pipe 4 and drops it into the storage tank 2 and into the distribution chamber 6. The vibration of the outer wall of the storage tank 2 by the vibrator 15 causes the powder to gather and gather into the distribution chamber 6. At this time, the opposite sides of the two connected partitions 11 are flush with the two sides of the feeding trough 7 to form an independent distribution area. As the powder continues to gather into the distribution area and is accompanied by the vibration of the vibrator 13 on the rotating shaft 9, the powder in the distribution area is vibrated and made uniform. Then the motor 10 is activated to drive the rotating shaft 9 to rotate. When the opposite sides of the two connected partitions 11 of the next group are aligned with the two sides of the feeding trough 7, the motor 10 stops and loads the new distribution area, and continues the above actions to achieve the purpose of uniform powder distribution each time.
