[0028] The following will specifically describe the preferred embodiments of the present utility model in conjunction with the drawings. The drawings constitute a part of this application and are used together with the embodiments of the present utility model to explain the principles of the present utility model, rather than to limit the scope of the present utility model.

[0029] A powder lifting and feeding device in this embodiment relates to the technical field of powder production. A push plate 210 is provided opposite to the hopper 120, and the hopper 120 moves intermittently relative to it. The push plate 210 can level the powder in the hopper 120 one by one, so that the volume of the powder stored in each hopper 120 is kept consistent, realizing accurate feeding.

[0030] Please refer to Figures 1 to 6 , a powder lifting and feeding device in this embodiment includes: a bucket elevator assembly 100 and a leveling assembly 200. The bucket elevator assembly 100 can lift equal-volume powders one by one with the hopper 120 to realize the regulation of the feeding amount. The leveling assembly 200 can level the protruding powder on the hopper 120 to fix the volume of the hopper 120 and improve the accuracy of the feeding amount.

[0031] The bucket elevator assembly 100 includes a rotatable annular transmission member 110 and buckets 120 for containing powder materials. The two ends of the annular transmission member 110 are respectively connected to a lower position and a higher position. The annular transmission member 110 is connected to a plurality of buckets 120. The buckets 120 can scoop up the powder materials, and the annular transmission member 110 can drive the buckets 120 to move intermittently, transporting the buckets from the lower position to the higher position to achieve feeding into the tank body at the higher position.

[0032] The leveling assembly 200 includes a movable push plate 210. The push plate 210 is precisely adapted to the opening of the bucket 120. The push plate 210 can level the excess powder materials protruding on the bucket 120 to ensure that the volume of the powder materials contained in the bucket 120 reaches a constant standard volume. Regardless of how much powder material the bucket 120 loads from the powder pile, the push plate 210 will correct the amount of powder material for each feeding, avoiding feeding deviation caused by uneven powder material accumulation or overloading, making the loading amount of the bucket 120 constant, and achieving precise control of the feeding amount.

[0033] In some embodiments, please refer to Figure 3 and Figure 4 , the bucket 120 is inclined relative to the outer side. During the process of the bucket 120 scooping up the powder materials, the protruding powder materials can slide down along the inclined surface, thereby preventing excessive powder material accumulation and reducing the workload of the push plate 210.

[0034] The inclination angle of the push plate 210 is the same as that of the bucket 120, and the push plate 210 can closely fit the surface of the opening of the bucket 120. When the push plate 210 moves, it can more effectively level the protruding powder materials in the bucket 120, reduce the frictional resistance between the push plate 210 and the bucket 120, ensure that the powder materials are evenly and quickly pushed back into the bucket 120, and achieve the purpose of precisely controlling the volume of the bucket 120.

[0035] In some embodiments, please refer to Figure 5 and Figure 6 , the leveling assembly 200 further includes a linear drive member 220. The output end of the linear drive member 220 is fixedly connected to the push plate 210, and the fixed end of the linear drive member 220 is connected to the frame. The linear drive member 220 can push the push plate 210 to perform precise linear movement. The linear drive member 220 can accurately control the displacement distance and speed of the push plate 210 to ensure that the push plate 210 can reach the predetermined position in each working cycle and match the opening height of the bucket 120. With the automatic control of the linear drive member 220, it is possible to avoid insufficient or excessive pushing caused by human or mechanical errors, thereby ensuring the accuracy of each feeding amount. The leveling action can be automatically executed according to the preset program of the system to ensure that each leveling action is carried out at the correct time to meet the continuity requirements of the production line.

[0036] In the specific implementation process, the linear drive 220 can be a cylinder. The cylinder uses compressed air as the power source to push the piston rod to form a linear motion, thereby driving the push plate 210 to move linearly.

[0037] The linear drive 220 can be a hydraulic cylinder. The hydraulic oil drives the piston rod to generate a linear motion, thereby driving the push plate 210 to move linearly.

[0038] The linear drive 220 can be an electric push rod. The electric push rod realizes linear motion through a motor-driven screw or gear system. The electric push rod can precisely control its stroke and speed through an electric control system, driving the push plate 210 to move linearly.

[0039] The linear drive 220 can be a combination of a ball screw and a stepper / servo motor. The stepper motor or servo motor drives the ball screw to rotate, and the rotational motion of the screw is converted into a linear motion of the nut, driving the push plate 210 to move linearly.

[0040] In some embodiments, please refer to Figure 6 , the leveling assembly 200 further includes a sensing unit 230 disposed opposite to the hopper 120. The sensing unit 230 is electrically connected to the linear drive 220. When the hopper 120 reaches the designated position, the sensing unit 230 is automatically triggered. After the sensing unit 230 is triggered, the linear drive 220 can be started to drive the push plate 210 to level the protruding powder in the hopper 120.

[0041] In the specific implementation process, the sensing unit 230 is a photoelectric sensor. The photoelectric sensor detects the presence of an object by emitting and receiving light beams. When the hopper 120 approaches, the light beam is blocked or reflected, thereby triggering the sensor to act.

[0042] The sensing unit 230 is an inductive sensor: The inductive sensor can detect the metal hopper 120 and detect the approach of the hopper 120 by sensing the change in the magnetic field.

[0043] The sensing unit 230 is a limit switch. When the hopper 120 approaches and touches the limit switch, the switch is triggered.

[0044] In some embodiments, please refer to Figure 5 , a powder lifting and feeding device further includes a vibration assembly 300. The vibration assembly 300 includes a vibrator 310. The vibrator 310 is disposed opposite to the annular transmission member 110. The vibrator 310 can vibrate the hopper 120 passing through the vibrator 310, making the powder in the hopper 120 more compact, avoiding the appearance of cavities, and further ensuring the consistency of the volume of the powder loaded in each hopper 120.

[0045] In the specific implementation process, the vibrator 310 is arranged between the leveling component 200 and the material pile. After the hopper 120 shovels up the powder in the material pile, the vibrator 310 first vibrates the area of the annular transmission member 110, making the powder in the hopper 120 more compact and shaking off some of the powder on the hopper 120. The hopper 120 that has passed through the vibrator 310 is then leveled by the push plate 210. After being leveled, the hopper 120 is farther away from the vibrator 310 and is less affected.

[0046] In some embodiments, please refer to Figure 4 , the bucket elevator assembly 100 further includes an annular housing 130 and a driving wheel 140. The annular transmission member 110 is arranged in the inner cavity of the annular housing 130. The annular housing 130 provides a closed or semi-closed working space for the annular transmission member 110 and the hopper 120, which can effectively fix and support the entire lifting system and prevent the annular transmission member 110 from shifting, shaking or falling off during operation.

[0047] The annular transmission member 110 is sleeved between the two driving wheels 140. The relative rotation of the driving wheels 140 can drive the annular transmission member 110 to rotate. The annular transmission member 110 is a chain or a belt, and the hopper 120 is connected to the annular transmission member 110 by bolts. The driving wheel 140 is rotatably connected to the annular housing 130, and the driving wheel 140 can be driven to rotate intermittently by an external motor, thereby driving the annular transmission member 110 to rotate intermittently and realizing the overall drive of the bucket elevator assembly 100.

[0048] In some embodiments, please refer to Figure 1 and Figure 4 , the annular housing 130 is provided with a feed inlet 131 and a discharge outlet 132. The feed inlet 131 is arranged below the annular housing 130 and is communicated with the inner cavity of the annular housing 130. The discharge outlet 132 is arranged above the annular housing 130 and is communicated with the inner cavity of the annular housing 130. Materials can enter the lifting system from the bottom and gradually rise as the hopper 120 moves. The discharge outlet 132 is arranged above, so that the materials are discharged from the hopper 120 after being lifted to the specified height, realizing continuous transportation from the low place to the high place and completing the lifting process of the materials.

[0049] The positions of the feed inlet 131 and the discharge outlet 132 are designed to follow the natural gravity direction of the upward transportation of the materials. The hopper 120 is gradually lifted under the drive of the annular transmission member 110. This vertical lifting method of the materials can reduce the additional power consumption and improve the transportation efficiency.

[0050] By reasonably designing the positions of the feed inlet 131 and the discharge outlet 132, it is possible to ensure that each hopper 120 is accurately loaded when passing through the feed inlet 131 and accurately unloaded when reaching the discharge outlet 132. This avoids waste of materials and excessive jitter, helps to maintain the accuracy and consistency of the feeding process, and improves the efficiency of the entire feeding process.

[0051] In some embodiments, referring to Figure 1 and Figure 2 , a powder lifting and feeding device further includes a dust suction assembly 400. The dust suction assembly 400 includes a suction pipe 410, and the suction pipe 410 communicates with the annular housing 130. Dust is easily generated during the lifting and feeding process of the powder, especially during the feeding and discharging stages. If the dust is not controlled, it will spread outside the equipment, causing pollution to the working environment. By timely sucking away the overflowing dust through the suction pipe 410, the diffusion of dust can be effectively reduced, the production environment can be kept clean, and the health hazards to the operators can be reduced.

[0052] Long-term accumulation of dust will deposit inside and outside the equipment, which may cause problems such as blockage and increased wear during equipment operation, and even affect the service life of the equipment. The dust suction assembly 400 can timely suck away the escaping dust, reduce the deposition of dust on components such as the annular transmission member 110 and the hopper 120, thereby extending the maintenance cycle and service life of the equipment.

[0053] The dust suction assembly 400 further includes a suction fan and a filter box. The suction pipe 410 is sequentially connected to the filter box and the suction fan. The suction fan can suck the dust-containing air in the annular housing 130 and enrich the dust in the filter box, which can effectively reduce the diffusion of dust and keep the production environment clean.

[0054] Working process: First, start the drive system of the bucket elevator to make the annular drive member 110 start to operate, driving the hopper 120 to intermittently move along the annular housing 130. Then, feed the powder into the annular housing 130 of the lifting device from the feed inlet 131, and adjust the powder load of each hopper 120 through the push plate 210 to ensure that the volume of each feeding is consistent. Next, the hopper 120 is gradually lifted from the lower feed inlet 131 to the upper discharge outlet 132 under the drive of the drive system. The push plate 210 can ensure the flatness and consistency of the powder in the hopper 120 and improve the accuracy of feeding.

[0055] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the present invention.
