[0029] Refer to Figures 1-6 , a protective gas automatic adjustment device, including a connecting pipe 1, a filtering pipe 2 and an adjusting block 3. The filtering pipe 2 and the adjusting block 3 are both communicated with the connecting pipe 1. An adjusting rod 4 is arranged on the surface of the adjusting block 3, and through holes of different sizes are arranged on the surface of the adjusting rod 4. A filter cartridge 8 is arranged inside the filtering pipe 2. A cleaning rod 13 is arranged inside the filtering pipe 2. Brush hairs 15 are arranged on the surface of the cleaning rod 13. A collecting cylinder 6 is arranged at the bottom of the filtering pipe 2. A motor 7 is fixedly installed at the top of the filtering pipe 2. The output shaft of the motor 7 rotates through the top of the filtering pipe 2 and is fixedly connected to the filter cartridge 8. During use, the protective gas passes through the filtering pipe 2 from the connecting pipe 1, and then the adjusting block 3 and the adjusting rod 4 adjust the passing amount of the protective gas. The filter cartridge 8 inside the filtering pipe 2 is used to filter impurities in the protective gas. At the same time, a cleaning rod 13 is arranged inside the filtering pipe 2, and the filter cartridge 8 can rotate under the action of the motor 7. Therefore, relative rotation can occur between the filter cartridge 8 and the cleaning rod 13. Furthermore, the brush hairs 15 on the cleaning rod 13 can clean the filter cartridge 8, reducing the situation where the protective gas cannot adjust the passing amount due to blockage. After the brush hairs 15 clean the impurities filtered on the filter cartridge 8, they will directly fall into the collecting cylinder 6, and the collecting cylinder 6 is used for unified collection, facilitating centralized treatment. The adjusting rod 4 can slide vertically in the adjusting block 3, so that the through holes of different sizes on the adjusting rod 4 are communicated with the adjusting block 3, thereby facilitating the control of the output amount of the protective gas.

[0030] Furthermore, the connecting pipe 1 includes a first pipe 101, a second pipe 102 and a third pipe 103. The first pipe 101 and the second pipe 102 are arranged on both sides of the filtering pipe 2, and both the first pipe 101 and the second pipe 102 are communicated with the filtering pipe 2. The second pipe 102 is inserted into the filtering pipe 2, and its port is in contact with the filter cartridge 8. Through holes are arranged on the surface of the adjusting block 3, and both sides of the adjusting block 3 are communicated with the second pipe 102 and the third pipe 103 respectively.

[0031] Further, the bottom of the collection cylinder 6 is threadedly connected to the filter tube 2. A connection block 9 is fixedly installed inside the filter tube 2. The connection block 9 is of an annular structure. A second connection frame 17 is fixedly installed on the inner wall of the connection block 9. A tapered block 10 is arranged on the surface of the second connection frame 17. A fixing rod 19 is fixedly installed at the bottom of the tapered block 10. The fixing rod 19 slidably penetrates through the second connection frame 17. A first spring 18 is sleeved on the surface of the fixing rod 19. A fixing block is fixedly installed at the bottom end of the fixing rod 19. Two ends of the first spring 18 are respectively fixedly connected to the fixing block and the second connection frame 17. By providing the connection block 9 and the tapered block 10, when the collection cylinder 6 is installed into the filter tube 2, it will push against the fixing rod 19, and the fixing rod 19 will drive the tapered block 10 to move upward, so that a certain gap is maintained between the tapered block 10 and the inner wall of the connection block 9, thus facilitating the impurities cleaned down to directly fall through the gap. When it is necessary to clean the collection cylinder 6, the collection cylinder 6 needs to be disassembled. During this process, in order to enable the protective gas to flow normally and not escape from the bottom of the filter tube 2, at this time when the collection cylinder 6 is disassembled, the entire tapered block 10 and the fixing rod 19 will slowly move downward under the restoring force of the spring until the outer wall of the tapered block 10 contacts the inner wall of the connection block 9, thereby achieving sealing, and further preventing the protective gas from escaping from the bottom. Therefore, the collection cylinder 6 can be directly disassembled.

[0032] Further, a first connection frame 11 is fixedly installed on the surface of the collection cylinder 6. A round block is rotatably connected to the surface of the first connection frame 11. By providing the first connection frame 11 and the round block, when the collection cylinder 6 is installed, the round block can be used to contact the fixing rod 19, thereby achieving the purpose of jacking up the fixing rod 19, enabling the fixing block to drive the tapered block 10 to move upward, and further facilitating the creation of a gap between the tapered block 10 and the connection block 9 for the impurities to fall.

[0033] Further, two bolts 12 are threadedly penetrated through the top of the filter tube 2. A cleaning rod 13 slidably penetrates through the bolts 12. A limiting block 16 is fixedly installed on the surface of the cleaning rod 13. Limiting grooves are evenly opened at the top ends of the bolts 12. By providing the cleaning rod 13 and the brush bristles 15, the rotating filter cylinder 8 can be cleaned. The cleaning rod 13 can rotate a certain angle in the bolts 12, and then the cleaning rod 13 is pushed downward to engage the limiting rod on the surface with the limiting grooves on the bolts 12, thereby achieving fixation, and further facilitating the contact of the brush bristles 15 on the other side with the filter cylinder 8.

[0034] Further, two annular pieces 14 are sleeved on the surface of the cleaning rod 13 in a sliding manner, and a second spring 20 is sleeved on the surface of the cleaning rod 13. The two ends of the second spring 20 are respectively fixedly connected to the two annular pieces 14. The cleaning rod 13 changes its angle to make the bristles 15 at different positions contact the filter cartridge 8. When changing the angle, it is necessary to pull up the cleaning rod 13 and then press down the cleaning rod 13. For the convenience of operation, two annular pieces 14 are arranged on the cleaning rod 13. When pulling up the cleaning rod 13, the upper annular piece 14 contacts the bolt 12, compressing the spring. Then, the cleaning rod 13 is rotated. When rotating, it will drive the two annular pieces 14 to rotate synchronously. After rotating to a fixed angle, the cleaning rod 13 is released. Under the action of the spring, the cleaning rod 13 will move downward until the limiting rod is engaged with the limiting groove, enhancing the stability.

[0035] Further, connecting ears are fixedly installed on both sides of the adjusting block 3. Electric telescopic rods 5 are fixedly installed on the surfaces of the two connecting ears. The output ends of the two electric telescopic rods 5 are fixedly connected to the adjusting rod 4. By cooperating the electric telescopic rods 5 with the adjusting rod 4 to drive the sliding of the adjusting rod 4, it is convenient to automatically adjust the passing amount of the protective gas.

[0036] An adjusting device includes the above-mentioned automatic adjusting device for the protective gas.

[0037] In summary, during use, the protective gas passes through the filter tube 2 through the connecting tube 1, and then the regulating block 3 and the regulating rod 4 regulate the amount of the protective gas passing through, and the filter cartridge 8 inside the filter tube 2 is used to filter the impurities in the protective gas. At the same time, a cleaning rod 13 is provided inside the filter tube 2, and the filter cartridge 8 can be rotated under the action of the motor 7, so that the filter cartridge 8 and the cleaning rod 13 can be relatively rotated, and then the bristles 15 on the cleaning rod 13 can be used to clean the filter cartridge 8, thereby reducing the situation where the protective gas cannot adjust the amount of passing through due to blockage. The bristles 15 clean the impurities filtered out of the filter cartridge 8 and the impurities will fall directly into the collecting tube 6, and the collecting tube 6 is used to realize unified collection, which is convenient for centralized processing, and the regulating rod 4 can Slide vertically in the adjusting block 3 so that the through holes of different sizes on the adjusting rod 4 are connected with the adjusting block 3, so as to facilitate the control of the output of the protective gas. By setting the connecting block 9 and the conical block 10, when the collecting cylinder 6 is installed into the filter tube 2, it will hold up the fixing rod 19, and the fixing rod 19 will drive the conical block 10 to move upward, so that a certain gap is maintained between the conical block 10 and the inner wall of the connecting block 9, so as to facilitate the cleaned impurities to fall directly through the gap. When the collecting cylinder 6 needs to be cleaned, the collecting cylinder 6 needs to be disassembled. In this process, in order to allow the protective gas to circulate normally and not escape from the bottom of the filter tube 2, when the collecting cylinder 6 is disassembled, the entire conical block 10 and the fixing rod 19 will be under the restoring force of the spring. The fixing rod 19 and the conical block 10 are slowly moved downward until the outer wall of the conical block 10 contacts the inner wall of the connecting block 9, thereby achieving a seal and preventing the protective gas from escaping from the bottom. Therefore, the collecting cylinder 6 can be directly disassembled. By setting the first connecting frame 11 and the round block, the collecting cylinder 6 can be installed by using the round block to contact the fixing rod 19, thereby lifting the fixing rod 19, so that the fixing block drives the conical block 10 to move upward, thereby facilitating the leaving of a gap between the conical block 10 and the connecting block 9 for impurities to fall. By setting the cleaning rod 13 and the bristles 15, the rotating filter cartridge 8 can be cleaned. The cleaning rod 13 can be rotated at a certain angle in the bolt 12, and then the cleaning rod 13 is pushed downward to make the limiting rod on the surface contact with the brush 15. The limiting groove on the bolt 12 is engaged, thereby achieving fixation, and then facilitating the contact of the bristles 15 on the other side with the filter cartridge 8. The cleaning rod 13 changes its angle to achieve contact of the bristles 15 with the filter cartridge 8 at different positions. When changing the angle, the cleaning rod 13 needs to be pulled upward, and then the cleaning rod 13 needs to be pressed downward. In order to facilitate the operation, two annular plates 14 are arranged on the cleaning rod 13. When the cleaning rod 13 is pulled upward, the upper annular plate 14 contacts the bolt 12, so that the spring is compressed, and then the cleaning rod 13 is rotated. When rotating, the two annular plates 14 will be driven to rotate synchronously. After rotating to a fixed angle, the cleaning rod 13 is released. Under the action of the spring, the cleaning rod 13 will move downward until the limiting rod is engaged with the limiting groove to enhance stability.The electric telescopic rod 5 cooperates with the adjusting rod 4 to drive the sliding of the adjusting rod 4, so as to facilitate the automatic adjustment of the passing amount of the protective gas.
