[0038] An inner disk 11 is installed in the first sealing plate 10. The inner disk 11 is rotatably sealed and connected to the first sealing plate 10, and a driving device for driving the inner disk 11 to rotate is arranged on the first sealing plate 10.

[0039] The driving device includes a second gear ring 12 concentrically fixed on the inner disk 11 , a second motor 14 is fixed on the first sealing plate 10 , a second gear 13 is concentrically fixed on the output shaft of the second motor 14 , and the second gear 13 meshes with the second gear ring 12 .

[0040] The inner plate 11 is provided with a long groove 15 , in which a plug strip 19 is inserted in a sliding and sealing manner. An elastic member is fixed to the lower end of the plug strip 19 , and the lower end of the elastic member is fixedly connected to the lifting plate 17 , and the lifting plate 17 is fixedly connected to the connecting rod 36 . The elastic member includes two elastic sheets 18 .

[0041] After the lifting plate 17 is located in the long groove 15, the lifting plate 17 is in sealing contact with the groove wall of the long groove 15. After the elastic member is located in the long groove 15, the elastic member is in sealing contact with the groove wall of the long groove 15.

[0042] Specifically, the upper ends of the two elastic sheets 18 are fixedly connected to the lower ends of the inserting strips 19 , and the lower ends of the two elastic sheets 18 are fixedly connected to the upper end of the lifting plate 17 .

[0043] A slide 16 is fixed to the lower end of the inner plate 11 , and the elastic member and the lifting plate 17 are slidably arranged in the slide 16 .

[0044] The lower end of the inner disk 11 is provided with a driving assembly capable of driving the connecting rod 36 to move up and down. The driving assembly includes a first motor 20 fixed to the lower end of the inner disk 11, a reciprocating screw 21 is coaxially fixed to the output shaft of the first motor 20, and the reciprocating screw 21, the connecting rod 36 and the balls in the connecting rod 36 constitute a ball screw pair.

[0045] An inverted U-shaped inner plate 26 is fixed in the water tank 22. Specifically, the inner plate 26 is fixed in the water tank 22 by a fixing rod 27. A first one-way valve 29 and a second one-way valve 30 are respectively fixedly and sealedly installed in the openings at the middle positions of the two vertical parts of the inner plate 26, and the opening in which the second one-way valve 30 is installed is connected to a pipeline, and the pipeline is connected to a spray assembly at the upper end of the hopper 3.

[0046] Specifically, the spray assembly includes an annular tube 33 located above the hopper 3, the annular tube 33 is fixedly connected to the outer wall of the hopper 3 through a third fixing member 34, and a plurality of nozzles 35 are evenly distributed and fixedly connected to the lower end of the annular tube 33, and the water sprayed from the nozzles 35 can flush the inner wall of the hopper 3.

[0047] The pipeline includes a first pipeline 31 and a second pipeline 32. One end of the second pipeline 32 is connected to the annular pipe 33, and the other end of the second pipeline 32 is connected to the first pipeline 31. The first pipeline 31 is connected to an opening in which a second one-way valve 30 is fixedly sealed and installed.

[0048] The paste mixing machine 1 conveys the lead paste to the hopper 3, and adds lignin and humic acid to the lead paste in the hopper 3 to increase the capacity of the negative electrode plate in a low temperature environment. After adding lignin and humic acid to the lead paste in the hopper 3, the pneumatic motor is started, and the cooperation of the first gear 8 and the first gear ring 6 causes the scraper 7 to rotate, thereby stirring the lead paste in the hopper 3.

[0049] The first motor 20 is started, and the first motor 20 drives the reciprocating screw 21 to rotate, thereby causing the connecting rod 36, the lifting plate 17, the elastic member and the inserting strip 19 to move upward. When the lifting plate 17 is located in the long slot 15, the second motor 14 is started, and the second motor 14 causes the inner disk 11 to rotate through the second gear 13 and the second gear ring 12. During the rotation of the inner disk 11, the connecting rod 36, the lifting plate 17, the elastic member and the inserting strip 19 rotate. When the inner disk 11 rotates, the inserting strip 19 and the elastic member can stir the lead paste in the hopper 3. After the heating plate 4 is started, the heating plate 4 can heat the lead paste in the hopper 3.

[0050] Since the lifting plate 17 is in sealing contact with the groove wall of the long groove 15 after the lifting plate 17 is located in the long groove 15, and the elastic member is in sealing contact with the groove wall of the long groove 15 after the elastic member is located in the long groove 15, the lead paste can be prevented from flowing out of the long groove 15 during the upward movement of the inserting strip 19 and the elastic member, and when the inserting strip 19 and the elastic member stir the lead paste in the hopper 3.

[0051] The telescopic rod is started to move the first sealing plate 10 away from the second sealing plate 24, thereby opening the lower end of the hopper 3. After the lower end of the hopper 3 is opened, the lead paste in the hopper 3 is discharged into the plate coating machine.

[0052] When the lead paste in the lower end of the hopper 3 clumps due to equipment shutdown, the first motor 20 is started, and the lifting plate 17, the elastic member and the insert 19 can puncture and crush the agglomerated lead paste blocking the lower end of the hopper 3 during the upward movement. The second motor 14 is started, and the lifting plate 17, the elastic member and the insert 19 intermittently move upward while the inner disk 11 rotates, which can increase the crushing area of ​​the agglomerated lead paste and improve the dredging effect. After the agglomerated lead paste in the lower layer is crushed, the telescopic rod is started to move the first sealing plate 10 away from the second sealing plate 24, and the crushed lead paste in the lower end of the hopper 3 is discharged, and the agglomerated lead paste in the upper layer descends and approaches the inner disk 11, and then the lifting plate 17, the elastic member and the insert 19 continue to crush the agglomerated lead paste above the inner disk 11.

[0053] When the agglomerated lead paste blocking the lower end of the hopper 3 is punctured and crushed, when the elastic member continues to move upward through the long slot 15, when the insert 19 is blocked by the agglomerated lead paste above it, the middle parts of the two elastic sheets 18 bend and move away from each other as the lifting plate 17 continues to move upward. When the lifting plate 17 moves downward, the two elastic sheets 18 are restored. During the restoration of the two elastic sheets 18, the lead paste located at the two elastic sheets 18 can be squeezed by the two elastic sheets 18, which can improve the efficiency of crushing the lead paste.

[0054] When the hopper 3 needs to be cleaned, the scraper 7 is rotated, and the lead paste adhering to the inner wall of the hopper 3 can be scraped off when the scraper 7 rotates.

[0055] After the telescopic rod is activated, the first sealing plate 10 moves to the lower end of the water tank 22 and can seal the lower end of the water tank 22. At this time, the second sealing plate 24 is away from the water tank 22 and compresses the spring 25. After the inner plate 26 corresponds to the long groove 15, the insert 19, the elastic member and the lifting plate 17 can enter the inner plate 26 after ascending. After the insert 19, the elastic member and the lifting plate 17 enter the inner plate 26, the two ends of the insert 19, the two ends of the elastic member and the two ends of the lifting plate 17 are sealed and contacted with the two vertical parts of the inner plate 26 respectively. After the insert 19 is pressed against the straight part at the upper end of the inner plate 26, as the lifting plate 17 continues to ascend, the middle parts of the two elastic sheets 18 bend and move away from each other. Since the lower end of the straight part of the inner plate 26 is provided with a groove 28, the insert 19 can be inserted into the groove 28, and the stability of the insert 19 can be ensured when the middle parts of the two elastic sheets 18 bend and move away from each other.

[0056] After the storage cavity formed by the insert strip 19, the two elastic sheets 18, the lifting plate 17 and the two vertical parts of the inner plate 26 are connected to the opening in which the first one-way valve 29 is installed, as the lifting plate 17 continues to move upward, the volume of the storage cavity increases, and the water in the water tank 22 enters the storage cavity through the first one-way valve 29. When the lifting plate 17 moves downward, the space of the storage cavity decreases, and the water in the storage cavity enters the spray assembly after passing through the second one-way valve 30, the first pipe 31 and the second pipe 32. The water entering the spray assembly is sprayed out through the nozzle 35 and then flushes the inner wall of the hopper 3. As the lifting plate 17 moves up and down intermittently, the volume of the storage cavity increases and decreases intermittently, and the water in the water tank 22 continuously enters the spray assembly.

[0057] After the inner wall of the hopper 3 is flushed, the insert 19, the elastic member, the lifting plate 17 and the connecting rod 36 are restored, and the telescopic rod is started to restore the first sealing plate 10. After the first sealing plate 10 is restored, the second sealing plate 24 is restored under the elastic force of the spring 25.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
