DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] The reciprocating assembly includes an electric push rod 25, which is arranged in a mounting groove 26. The mounting groove 26 is arranged on both side surfaces of the feed box 21. One end of the piston rod of the electric push rod 25 is connected to an adjusting block 27. The adjusting block 27 is arranged on both side surfaces of the mounting frame 24. It reciprocates through the screen 23 and screens the raw materials.
[0030] First, titanium dioxide or wollastonite is transported into the feed box 21 through the feed port 22, and then the electric push rod 25 is extended and retracted, and the electric push rod 25 drives the adjustment block 27 to move back and forth, and the adjustment block 27 drives the mounting frame 24 to move back and forth, and the mounting frame 24 drives the screen 23 to move back and forth. The reciprocating movement of the screen 23 can screen the titanium dioxide or wollastonite, and the screen 23 separates large particles of titanium dioxide or wollastonite from small particles of titanium dioxide or wollastonite. The small particles of titanium dioxide or wollastonite enter the mixing bin 5 through the feeding port 8 and are mixed.
[0031] In one specific embodiment, see Figure 3 , Figure 5 as well as Figure 6 A pair of roller structures 1 for crushing the large-particle raw materials after screening is arranged at the bottom of the feed box 21. The pair of roller structures 1 include a crushing box 101. The crushing box 101 is arranged on one side of the bottom of the feed box 21. A feeding port 103 is arranged on one side of the feed box 21. A first crushing roller 108 and a second crushing roller 109 are symmetrically arranged in the crushing box 101. A transmission component for driving the first crushing roller 108 and the second crushing roller 109 to rotate in opposite directions is arranged on the surface of one side of the crushing box 101, so as to crush the large-particle raw materials.
[0032] Specifically, the transmission assembly includes a first gear 110 and a second gear 113. The first gear 110 is arranged on one side of the first crushing roller 108, and the second gear 113 is arranged on one side of the second crushing roller 109. The first gear 110 is meshed with the second gear 113. The first crushing roller 108 is also connected to a drive motor 111 located on one side of a transmission box 112. The transmission box 112 is arranged on one side surface of the crushing box 101, so that the first crushing roller 108 and the second crushing roller 109 can rotate in opposite directions.
[0033] After the large particles of titanium dioxide or wollastonite are screened, the electric push rod 25 contracts to drive the mounting frame 24 to move, and the mounting frame 24 drives the screen 23 to move, and the screen 23 moves to push the large particles of titanium dioxide or wollastonite, and the large particles of titanium dioxide or wollastonite enter the crushing box through the drop port 103, and the first crushing roller 108 is driven to rotate by the driving motor 111, and the first crushing roller 108 drives the first gear 110 to rotate, and the first gear 110 drives the second gear 113 to rotate, and the second gear 113 drives the second crushing roller 109 to rotate, and the first crushing roller 108 and the second crushing roller 109 rotate in opposite directions to crush the large particles of titanium dioxide or wollastonite.
[0034] In the present application, a collecting hopper is arranged in the pulverizing box 101 at the lower side of the first pulverizing roller 108 and the second pulverizing roller 109, and the pulverized titanium dioxide or wollastonite is centrally transported to the collecting hopper. A conveying pipe 102 is arranged at the bottom of the pulverizing box 101, and the conveying pipe 102 is connected to the mixing bin 5, so that the pulverized titanium dioxide or wollastonite can be centrally transported to the mixing bin 5 for mixing.
[0035] In one specific embodiment, see Figure 3-Figure 5 The top rods 28 are symmetrically arranged on both sides of the mounting frame 24, which can push the sealing plate 104 to move. The sealing plate 104 is arranged in the feed box 21 on one side of the drop port 103. The sealing plate 104 is movably arranged on one side of the feed box 21 to seal the drop port 103 to prevent small particles of raw materials from entering the crushing box.
[0036] When the electric push rod 25 contracts, it drives the mounting frame 24 to move, and the mounting frame 24 drives the push rod 28 to move. When the push rod 28 contacts the sealing plate 104, as the mounting frame 24 moves, the push rod 28 drives the sealing plate 104 to move, and the sealing plate 104 is separated from the blanking port 103. At the same time, as the mounting frame 24 moves, large particles of titanium dioxide or wollastonite enter the crushing box 101 through the blanking port 103.
[0037] Specifically, a guide rod 105 is provided on the surface of one side of the sealing plate 104, and one end of the guide rod 105 is movably provided in a sleeve 107.

The movement of the sealing plate 104 can drive the guide rod 105 to move in the sleeve 107, and the movement of the guide rod 105 compresses the reset spring 106. When the large-particle titanium dioxide or wollastonite is conveyed, the mounting frame 24 resets and moves. At this time, the reset spring 106 drives the guide rod 105 to reset and move, and the guide rod 105 drives the sealing plate 104 to reset and move, and the sealing plate 104 automatically seals the blanking port 103.
[0038] In this application, please refer to Figure 2 The stirring structure 3 includes a stirring shaft 32, which is connected to a stirring motor, and a stirring blade 31 is arranged on the stirring shaft 32, and a scraper 33 is arranged at the bottom of the stirring shaft 32. Specifically, the scraper 33 can be a concave structure, which can fit with the bottom and side wall of the mixing bin 5. The rotation of the stirring shaft 32 drives the scraper 33 to rotate, which can mix the raw materials and scrape off the raw materials adhering to the inner wall of the mixing bin 5.
[0039] In order to support the mixing bin 5, a support frame 7 is arranged at the bottom of the mixing bin 5. Specifically, the support frame 7 can be set to 3 groups and arranged in a triangular support. A discharge pipe 6 is also arranged at the bottom of the mixing bin 5, and a reagent input pipe 4 is arranged on one side of the top of the mixing bin 5 to facilitate the input of reagent raw materials and the output of mixed paint.
