Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding machine technology, specifically a pneumatic vacuum feeding machine. Background Technology

[0002] A pneumatic vacuum conveyor, also known as a vacuum conveyor, is a dust-free, closed-pipe conveying device that uses vacuum suction to transport granular and powdery materials. It utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipe, which in turn drives the powdery materials to move, thus completing the conveying of the powder.

[0003] Existing pneumatic vacuum feeders transport powder through pipelines during operation. However, during storage, the powder is prone to becoming damp and clumping, causing it to get stuck in the conveying pipeline and blockage the pipeline. This affects the normal feeding of subsequent powder. Furthermore, the conveying pipeline requires continuous manual handling for feeding. If the pipeline is not manually handled, it will tilt inside the hopper and be pulled out by the weight of the external pipeline, making it impossible to continue feeding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pneumatic vacuum feeder, which solves the problem that powder materials are prone to becoming damp and clumping, causing clumped powder materials to get stuck in the conveying pipe, resulting in blockage of the conveying pipe and requiring continuous manual feeding.

[0006] Preferably, a limiting frame is provided at both the front and rear of the fixed tube, and a first rotating frame is fixedly connected to the opposite side of each of the two limiting frames, with a threaded cylinder rotatably connected inside the first rotating frame.

[0007] Preferably, the threaded cylinder has a first threaded rod internally threaded, and the front and rear of the fixed cylinder are both fixedly connected to a second rotating frame, the interior of which is rotatably connected to the first threaded rod.

[0010] Preferably, the front part of the clamping plate has a threaded opening for use with the second threaded rod.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a pneumatic vacuum feeder, including a vacuum feeder body 1 and a feeding hose 2 connected to the vacuum feeder body 1. The feeding hose 2 is equipped with a valve. One end of the feeding hose 2 is connected to a fixed pipe 3, which is a metal rigid pipe. One end of the fixed pipe 3 is connected to a feeding hopper 4. A fixed frame 5 is fixedly connected to the fixed pipe 3. A fixed cylinder 6 is fixedly connected to one side of the fixed frame 5. A motor 7 is fixedly connected inside the fixed cylinder 6. The motor 7 is a servo motor, electrically connected to an external power source, and controlled by a control switch. The output shaft of the motor 7 is fixedly connected to a rotating rod 8 through a coupling. One end of the rotating rod 8 passes through the fixed cylinder 6 and the fixed pipe 3 in sequence and extends into the inside of the feeding hopper 4. The fixed pipe 3 and the fixed cylinder 6 are respectively provided with a rotating port for cooperating with the rotating rod 8. A rotating sleeve 9 is fixedly connected to the surface of the rotating rod 8 and located inside the feeding hopper 4. Several rotating blades 10 are fixedly connected to the surface of the rotating sleeve 9.

[0024] Furthermore, in order to facilitate the adjustment of the length of the limiting frame 11, limiting frames 11 are provided at the front and rear of the fixed tube 3. A first rotating frame 12 is fixedly connected to the opposite side of the two limiting frames 11. A threaded cylinder 13 is rotatably connected inside the first rotating frame 12. A first threaded rod 14 is threadedly connected inside the threaded cylinder 13. A second rotating frame 15 is fixedly connected to the front and rear of the fixed tube 6. The interior of the second rotating frame 15 is rotatably connected to the first threaded rod 14.

[0025] Furthermore, in order to facilitate clamping and fixing the limiting frame 11 to the material barrel, a sliding groove 18 is provided at the top of the inner cavity of the limiting frame 11. A sliding block 19 is slidably connected inside the sliding groove 18. A clamping plate 17 is fixedly connected to the bottom of the sliding block 19. The two inner cavities of the limiting frames 11 are rotatably connected to a second threaded rod 16 through a bearing. One end of the second threaded rod 16 passes through the clamping plate 17 and extends to the outside of the clamping plate 17. A threaded opening is provided at the front of the clamping plate 17 to cooperate with the second threaded rod 16.

[0026] In use, the fixing tube 3 is inserted into the powder in the material bucket, and then the two limiting frames 11 are swung upward to flip them to the top. By rotating the limiting frames 11, the threaded cylinder 13 is rotated, and the first threaded rod 14 extends out from the threaded cylinder 13, increasing the length of the threaded cylinder 13 and the first threaded rod 14. The limiting frames 11 are then extended to the top of the material bucket, and the limiting frames 11 are placed on the inner wall of the material bucket. By rotating the handle, the second threaded rod 16 is rotated, and the second threaded rod 16 will drive the clamping plate 17 to move. The clamping plate 17 will move closer to the limiting frames 11, so that the limiting frames 11 and the clamping plate 17 are clamped on the inner wall of the material bucket. The two limiting frames 11 suspend the fixing tube 3 through the threaded cylinder 13 and the first threaded rod 14, and the fixing tube 3 is stably inserted into the powder in the material bucket.

[0027] The vacuum feeder body 1 is evacuated to a vacuum state. Then, the valve is opened and the powder in the bucket is fed through the feed hose 2, fixed pipe 3 and feed hopper 4. The powder is drawn into the vacuum feeder body 1 through the fixed pipe 3 and feed hose 2. At the same time, the motor 7 drives the rotating rod 8 to rotate. The rotating rod 8 drives the rotating sleeve 9 to rotate. The rotating sleeve 9 drives multiple rotating blades 10 to rotate. The multiple rotating blades 10 rotate the powder entering the feed hopper 4, breaking up the clumps of powder and feeding it onto the feeder body. After the vacuum feeding in the vacuum feeder body 1 is completed, the valve is closed and the powder is discharged through the opening at the bottom of the vacuum feeder body 1.
