A fourth switch valve 68 and a third one-way valve 69 are arranged on the third pipe 67. The auxiliary component can control the working of the feeding component and the efficiency-enhancing component.

[0059] The using process of the present invention is as follows: When producing photovoltaic silver paste, the liquid raw materials are added to the mixing box 2 through the hopper 12, and then the powder raw materials are added to the storage tank 3;

[0060] Next, the switch valve 2 62 is closed, the switch valve 3 64 is opened, the switch valve 4 68 is opened, and then the motor 8 is controlled to work, the motor 8 drives the reciprocating screw 10 to rotate, the reciprocating screw 10 rotates to drive the chain 19 to rotate, the chain 19 rotates to drive the rotating shaft 4 to rotate, the rotating shaft 4 rotates to drive the stirring rod 5, the scraping bar 6, the scraping rod 7 and the synergistic component to rotate inside the mixing box 2, so that the stirring and mixing work can be carried out, wherein the reciprocating screw 10 can also make the sliding seat 11, the base rod 58 and the piston three 57 move up and down when rotating, and the activity When the piston 57 moves downward, the outside air can enter the box 2 56 through the pipe 3 67 and the one-way valve 3 69. When the piston 57 moves upward, the air in the box 2 56 can enter the lower half of the box 1 42 through the three-way pipe 59, the pipe 2 63 and the one-way valve 2 65. In this way, the box 1 42 can be continuously filled with air. In this way, the pressure in the lower half of the box 1 42 will increase, and the air cushion 53 will be inflated and increased. When the pressure in the lower half of the box 1 42 exceeds the threshold of the safety valve 49, the safety valve 49 will automatically close. The first box 42 is opened automatically, and then the pressure in the lower half of the box body 1 is released, so that the piston 2 43, the reciprocating rod 44, the moving frame 45 and the tooth plate 46 can be instantly pushed upward. At the same time, the spring 47 is compressed, and the tooth plate 46 moves upward, which can make the gear 41, the rotating shaft 39 and the spiral blade 40 rotate several times. The spiral blade 40 rotates several times to transport the powdered raw material to the right, so that the powdered raw material can fall into the mixing box 2. When the pressure is released, the piston 2 43, the reciprocating rod 44, the moving frame 45 and the tooth plate are rebounded by the spring 47. 46 moves downward to reset, and the excess air in the upper half of the box body 2 56 returns to the lower half through the one-way valve 1 50, and at the same time the air cushion 53 is inflated and becomes larger, so that the material can be added once at the moment of pressure release. Since air is continuously filled into the box body 1 42 at this time, the material can be added once every period of time, so that the material can be added to the mixing box 2 intermittently, which can avoid the phenomenon that too much material is added at one time and the mixing quality is reduced, and at the same time, it can also avoid the phenomenon that the rotating shaft 4 cannot rotate due to too much dry material;

[0061] When adding materials intermittently, the rotating shaft 1 4 will also drive the stirring rod 5, the scraper bar 6, the scraper rod 7 and the synergistic component to rotate inside the mixing box 2, so that the materials can be continuously stirred and mixed. In addition, the gear 41 is connected to the rotating shaft 39 through a one-way bearing, so the rotating shaft 39 will not rotate when the tooth plate 46 moves downward;

[0062] After the powder material is added, control the opening of the second switching valve 62, close the third switching valve 64 and the fourth switching valve 68. Then, control the motor 8 to continue rotating. In this way, the first rotating shaft 4 still drives the stirring rod 5, the scraping strip 6, the scraping rod 7 and the efficiency enhancement component to rotate inside the mixing tank 2. The difference is that under the action of the first pipeline 60, the piston 57 moves up and down, which can make the air in the second box body 56 and the first rotating shaft 4 circulate. Furthermore, the first piston 24, the push rod 25, the connecting rod 22 and the slider 20 move up and down. Since the outer frame 28 and the first U-shaped rod 27 are connected through a sealed bearing, and the pressing rod 29 and the second U-shaped rod 30 are connected through a sealed bearing, they can move relative to each other. When the slider 20 moves up and down, the pressing rod 29 and the outer frame 28 can move telescopically. When moving telescopically, the two dial plates 31, the two second rotating shafts 32 and the four dial rods 36 move reciprocally. Moreover, the convex block 35 is slidably embedded in the spiral groove 33 and the convex block 35 cannot move. When moving reciprocally, the two second rotating shafts 32 will also rotate on their own axes, thereby driving the four dial rods 36 to rotate. In this way, when the efficiency enhancement component rotates with the first rotating shaft 4, the dial plates 31 in the efficiency enhancement component will move reciprocally, and the second rotating shafts 32 and the dial rods 36 will rotate on their own axes. In this way, when mixing and pulping, the effect of stirring and mixing can be enhanced. Moreover, when the first piston 24 moves up to a certain extent, the pulp can be sucked into the first rotating shaft 4. When the first piston 24 moves down, the sucked pulp can be squeezed out. In this way, the pulp can be turned over, thereby avoiding the phenomenon of insufficient stirring and mixing;

[0063] After the pulping is completed, place a container for receiving materials at the bottom of the discharge pipe 13, and then open the first switching valve 14, so that the pulp can be discharged through the discharge pipe 13.

[0064] The above are only the preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection required by the present invention.
