Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, specifically to a high-efficiency automatic powder supply device. Background Technology

[0002] In industries such as chemical, food, and pharmaceutical, powder conveying is controlled by pipe fittings during processing, and then the flow of powder is controlled by gates, which can automatically and efficiently transfer the powder to the required scene.

[0003] In industries such as chemical, food, and pharmaceutical, airflow is often used to move powder within pipelines. Gates are used to control the flow and stop the flow. Some gates have a gate plate slightly larger than the pipe diameter for easier passage, allowing the powder to pass quickly. However, when the powder passes through the gate or stops at the gate, it can get stuck in the gap between the pipe and the gate plate, causing leakage. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a high-efficiency automatic powder feeding device, which reduces the leakage of powder when it is near the gate during the powder conveying process, thus affecting the accuracy of the feeding.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a high-efficiency automatic powder feeding device, including a conveying pipe, a square tube fixedly connected between two conveying pipes, an arc-shaped frame fixedly connected to one side of the square tube, the arc-shaped frame communicating with the square tube, a drive motor fixedly connected to one side of the arc-shaped frame, a rotating rod fixedly connected to the output end of the drive motor, baffles fixedly connected to the four mutually distant sides of the rotating rod, a fixed cylinder fixedly connected to the side of the square tube away from the arc-shaped frame, an electric push rod fixedly connected to the end of the fixed cylinder away from the arc-shaped frame, a pressure frame fixedly connected to the output end of the electric push rod, receiving grooves contacting both sides of the pressure frame, the receiving grooves being located on both sides inside the square tube, a strip groove opened on the side of the arc frame near the square tube, a spring strip inserted into the strip groove, the end of the spring strip contacting the baffle.

[0006] As a preferred technical solution of this utility model, a first air pump is fixedly connected to the upper end of the fixed cylinder. The output end of the first air pump is connected to the inside of the fixed cylinder. By setting the first air pump, the inside of the fixed cylinder is in a positive pressure state, which reduces the amount of powder entering the fixed cylinder and contacting the output end of the electric push rod.

[0007] As a preferred technical solution of this utility model, a folding cover is fixedly connected to one side of the fixed cylinder, and the other end of the folding cover is fixedly connected to one end of the pressure frame. The folding cover is located outside the output end of the electric push rod. By setting the folding cover, the contact between the powder and the output end of the electric push rod can be further reduced.

[0008] As a preferred technical solution of this utility model, an air groove is provided on the upper side of the arc-shaped frame, and a second air pump is fixedly connected to the arc-shaped frame at the air groove. An outlet groove is provided on the bottom side of the arc-shaped frame, and an outlet pipe is fixedly connected to the arc-shaped frame at the outlet groove. The bottom end of the outlet pipe is fixedly connected to and communicates with the bottom side conveying pipe. By setting the second air pump, the surface of the baffle can be cleaned, thereby promoting the powder to enter the bottom side conveying pipe from the outlet groove and the outlet pipe, thereby reducing the rotational stagnation caused by dust adhesion.

[0009] As a preferred technical solution of this utility model, a ventilation recess is provided on one side of the arc-shaped frame. The ventilation recess is located between the air groove and the outlet groove. By setting the ventilation recess, a larger gap is created between one of the baffles and the arc-shaped frame, which facilitates the guidance of dust.

[0010] This utility model has the following advantages: by setting a square tube and an arc frame between two conveying pipes, and forming an intermittent partition square tube by a rotating rod and a baffle, and then extending the electric push rod so that the pressure frame is on the bottom side of the baffle, thereby sealing the gap between the receiving groove and the square tube, thereby reducing material leakage and improving the feeding accuracy of powder through the pipe fittings and gate.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3The high-efficiency automatic powder feeding device shown includes a conveying pipe 1, with a square tube 2 fixedly connected between two conveying pipes 1. An arc-shaped frame 3 is fixedly connected to one side of the square tube 2, and the arc-shaped frame 3 communicates with the square tube 2. A drive motor, which is a stepper motor, is fixedly connected to one side of the arc-shaped frame 3. The drive motor drives a rotating rod 4 to rotate, thereby causing different baffles 5 to contact the inner side of the square tube 2, achieving internal sealing of the square tube 2. The output end of the drive motor is fixedly connected to the rotating rod 4, and baffles 5 are fixedly connected to the four mutually distancing sides of the rotating rod 4. A fixed baffle 5 is fixedly connected to the side of the square tube 2 away from the arc-shaped frame 3. The cylinder 6 is fixedly connected to an electric push rod 7 at one end away from the arc-shaped frame 3. The extension of the electric push rod 7 causes the pressure frame 8 to extend and be positioned on the bottom side of the baffle 5, thus blocking the gap between the inner wall of the square tube 2 and the baffle 5, reducing material leakage. The output end of the electric push rod 7 is fixedly connected to the pressure frame 8. Both sides of the pressure frame 8 are in contact with receiving grooves 9, located on both sides inside the square tube 2. The arc-shaped frame 3 has a strip groove 12 on the side closest to the square tube 2. A spring strip 13 is inserted into the strip groove 12, with its end in contact with the baffle 5. The end of the spring strip 13 is made of rubber and can be extended by contact. Figure 1 The upper and lower baffles 5 reduce the amount of powder entering the curved frame 3.

[0017] The upper end of the fixed cylinder 6 is fixedly connected to a first air pump 11. The output end of the first air pump 11 is connected to the inside of the fixed cylinder 6. By setting the first air pump 11, the first air pump 11 is inflated to make the fixed cylinder 6 a positive pressure state, thereby reducing the contact of dust with the output end of the electric push rod 7 inside the fixed cylinder 6.

[0018] The fixed cylinder 6 has a folding cover 10 fixedly connected to one side, and the other end of the folding cover 10 is fixedly connected to one end of the pressure frame 8. The folding cover 10 is located outside the output end of the electric push rod 7. By setting the folding cover 10, the contact of powder with the output end surface of the electric push rod 7 can be further reduced.

[0019] The arc-shaped frame 3 has an air groove 14 on its upper side, and a second air pump 15 is fixedly connected to the arc-shaped frame 3 at the air groove 14. The arc-shaped frame 3 has an outlet groove 17 on its bottom side, and an outlet pipe 18 is fixedly connected to the arc-shaped frame 3 at the outlet groove 17. The bottom end of the outlet pipe 18 is fixedly connected to and communicates with the bottom side conveying pipe 1. The second air pump 15 causes airflow to enter the arc-shaped frame 3 and sweeps away the powder adhering to the baffle 5, causing the adhering powder to enter the bottom side conveying pipe 1 from the outlet groove 17 and the outlet pipe 18.

[0020] Among them, a ventilation recess 16 is provided on one side of the arc-shaped frame 3. The ventilation recess 16 is located between the air groove 14 and the outlet groove 17. By setting the ventilation recess 16, air can be easily circulated.

[0021] Working principle: When the powder passes through, an arc-shaped frame 3 and a fixed cylinder 6 are set between the two conveying pipes 1. When it is necessary to stop the material, the drive motor causes one of the baffles 5 to make vertical contact with the inner wall of the square tube 2. Then, the electric push rod 7 extends to cause the pressure frame 8 to move in the receiving groove 9. The upper end of the pressure frame 8 contacts the gap between the baffle 5 and the inner wall of the square tube 2, thereby reducing the leakage of material. At the same time, the other baffles are located in the arc-shaped frame 3. The second air pump 15 provides blowing and causes the powder adhering to the baffle 5 to enter the bottom conveying pipe 1 from the outlet groove 17 and outlet pipe 18, thereby improving the accuracy of powder conveying.

[0022] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0023] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
