The filter cleaning device 6 uses a filter screen 63 to filter and intercept lumps in the powder raw material. When using the powder feeder, the sealing cap 4 is opened to add powder raw material into the storage tank 3. At this time, the filter cleaning device 6 can filter and intercept the lumps in the powder raw material. Then, the air pump inside the controller is started by pressing button 2 on the controller surface, and the powder raw material inside the storage tank 3 is then delivered to the designated location through the powder feeding pipe 5. During the powder feeding process, the sealing cap 4 can be opened to add powder to the storage tank 3 without stopping the machine.

[0027] Figures 1 to 6The filter cleaning device 6 shown includes bolts 61, a fixing plate 62, a filter screen 63, a motor 64, a rotating rod 65, a connecting plate 66, a spring 67, and a cleaning brush 68. Bolts 61 are inserted into one side of the fixing plate 62 to be threadedly fixed to the storage tank 3. One side of the filter screen 63 is connected to the fixing plate 62, and the size of the filter screen 63 is adapted to the size of the storage tank 3. The motor 64 is located in the middle area of ​​the filter screen 63, and the output end of the motor 64 is connected to the rotating rod 65. The connecting plate 66 is located on the side of the rotating rod 65 away from the motor 64. The two ends of the spring 67 are connected to the connecting plate 66 and the cleaning brush 68, respectively. The bristles of the cleaning brush 68 are in contact with the filter screen 63, and the size of the cleaning brush 68 is adapted to the size of the filter screen 63.

[0028] Figures 1 to 6 When using the filter cleaning device 6, the filter screen 63 is moved so that it is inside the storage tank 3. Then, the bolt 61 is rotated so that it passes through the fixing plates 62 fixed on both sides of the filter screen 63 to secure it to the storage tank 3. While the filter screen 63 is filtering clumps from the powder raw material, the motor 64 fixed at the upper end of the filter screen 63 is started. The output end of the motor 64 rotates through the rotating rod 65 fixed by the coupling. The rotating rod 65 then drives the connecting plate 66 fixed on one side to rotate. At this time, the connecting plate 66 rotates through the coupling. The spring 67, which is fixed to the cleaning brush 68, drives the cleaning brush 68 to move on one side of the filter screen 63. The spring 67 ensures that the bristles of the cleaning brush 68 are in close contact with the filter screen 63. Then, the cleaning brush 68 cleans the holes of the filter screen 63. By using the filter cleaning device 6, the clumps in the powder raw material can be filtered and intercepted, and the filter screen 63 can be cleaned, so that the filter screen 63 can be used for a long time. This prevents the clumps of powder raw material from entering the powder feeding pipe 5 and causing blockage, thereby improving the performance of the powder feeder.

[0029] Figures 1 to 6A limiting rod 69 is fitted inside the spring 67 shown. One side of the limiting rod 69 is connected to the cleaning brush 68, and the other side slides with the connecting plate 66. By fitting the limiting rod 69 inside the spring 67, with one side fixedly connected to the cleaning brush 68 and the other side slidingly connected to the connecting plate 66, the shape of the spring 67 is restricted, preventing the spring 67 from bending under force and affecting its use. A reinforcing plate 610 is provided on the side of the fixing plate 62 near the filter screen 63. One side of the reinforcing plate 610 is connected to the filter screen 63 to improve the connection strength between the fixing plate 62 and the filter screen 63. The fixed connection between the reinforcing plate 610 and the filter screen 63 and the fixing plate 62 improves the connection strength between the reinforcing plate 610 and the filter screen 63, preventing deformation at the connection point from affecting the use of the filter screen 63. A guide block 611 is provided on the side of the motor 64 away from the filter screen 63. The guide block 611 guides the powder material reaching the upper end of the motor 64 to detach. By fixing the motor 64 to the upper end of the guide block 611, the powder material reaching the upper end of the motor 64 is guided, so that the powder material can quickly detach from the upper end of the motor 64.

[0030] Figures 1 to 6 The storage tank 3 shown is equipped with a support and positioning device 7 inside. The support and positioning device includes a support ring 71, which is located inside the storage tank 3 and below the filter screen 63 to support the filter screen 63. When the filter screen 63 is placed inside the storage tank 3, the support ring 71 fixed inside the storage tank 3 supports the lower end of the filter screen 63, thus eliminating the need for the operator to support the filter screen 63 with one hand. This makes it easier to fix the filter screen 63 inside the storage tank 3. By using the support and positioning device, the filter screen 63 can be quickly supported and positioned, making it convenient for the operator to subsequently fix the filter screen 63 with bolts 61, thereby facilitating the subsequent use of the filter cleaning device 6.

[0031] Figures 1 to 6The support ring 71 shown has a through hole 72 on its surface. A positioning post 73 is provided on the side of the filter screen 63 away from the fixing plate 62. The positioning post 73 penetrates the through hole 72 on the surface of the support ring 71 to position the filter screen 63. When the filter screen 63 is supported by the support ring 71, the positioning post 73 fixed on one side of the filter screen 63 penetrates the through hole 72 on the surface of the support ring 71 to quickly position the filter screen 63 on the support ring 71. This allows the fixing plate 62 to be aligned more quickly with the threaded groove on the storage tank 3, facilitating the subsequent fixing of the fixing plate 62 and the filter screen 63 with bolts 61. The positioning post 73 is smaller on the side away from the filter screen 63 to make it easier for the positioning post 73 to penetrate the through hole 72 on the surface of the support ring 71. By making the positioning post 73 smaller on the side away from the filter screen 63, it is easier for the positioning post 73 to penetrate the support ring 71 to position the filter screen 63, thereby improving the effectiveness of the positioning post 73.

[0032] Working Principle: When using the powder feeder, open the sealing cover 4 to add powder raw materials into the storage tank 3. At this time, use the filter cleaning device 6 to filter and intercept any lumps in the powder raw materials. Then, activate the air pump inside the controller via button 2 on the controller surface. This allows the powder raw materials inside the storage tank 3 to be delivered to the designated location through the powder feeding pipe 5. During the powder feeding process, the sealing cover 4 can be opened to add powder to the storage tank 3 without stopping the machine. When using the filter cleaning device 6, move the filter screen 63 so that it is inside the storage tank 3. Then, rotate the bolt 61 so that it passes through the fixing plates 62 fixed on both sides of the filter screen 63 and is threadedly fixed to the storage tank 3. While the filter screen 63 is filtering the lumps in the powder raw materials, start the motor 64 fixed at the upper end of the filter screen 63. The output end of the motor 64 rotates through the rotating rod 65 fixed by the coupling. The rotating rod 65 then drives the connecting plate 66 fixed on one side to rotate. At this time, the connecting plate 66 rotates through the connecting plate 66 and... The cleaning brush 68 is fixed by a spring 67, which drives the cleaning brush 68 to move on one side of the filter screen 63. The spring 67 ensures that the bristles of the cleaning brush 68 are in close contact with the filter screen 63. Then, the cleaning brush 68 cleans the holes of the filter screen 63. By using the filter cleaning device 6, the clumps in the powder material can be filtered and intercepted, and the filter screen 63 can be cleaned, so that the filter screen 63 can be used for a long time. This prevents the clumps of powder material from entering the powder feeding pipe 5 and causing blockage, thereby improving the performance of the powder feeder.

[0033] When the filter screen 63 is placed inside the storage tank 3, the support ring 71 fixed inside the storage tank 3 supports the lower end of the filter screen 63. At this time, the positioning post 73 fixed on one side of the filter screen 63 passes through the through hole 72 on the surface of the support ring 71 to quickly position the filter screen 63 on the support ring 71. Then, when the filter screen 63 is fixed, the operator does not need to support the filter screen 63 with one hand, making it easier to fix the filter screen 63 inside the storage tank 3. By using the support and positioning device, the filter screen 63 can be quickly supported and positioned, and then it is convenient for the operator to use bolts 61 to fix the filter screen 63, thus facilitating the subsequent use of the filter cleaning device 6.
