[0037] Furthermore, an adjustment plate 24 is fixedly installed on the outside of the cross bar 10, and the adjustment plate 24 is fan-shaped. A guide groove 25 is opened on the side of the adjustment plate 24 away from the cross bar 10, and the guide groove 25 is wavy. Guide blocks 26 are fixedly installed above the No. 1 rolling piece 12 and the No. 2 rolling piece 14, and the guide blocks 26 and the guide grooves 25 are slidably matched.

[0038] Furthermore, blades 15 are fixedly installed on the outside of the No. 1 rolling piece 12 and the No. 2 rolling piece 14, the bottoms of the No. 1 rolling piece 12 and the No. 2 rolling piece 14 are both arc-shaped, and protrusions 16 are fixedly installed on the bottoms of the No. 1 rolling piece 12 and the No. 2 rolling piece 14.

[0039] Working principle: The ceramic slurry mixed with the adhesive and the additive is poured into the interior of the casting box 2 through the feed port 4, and flows to the top of the equipment body 1 through the discharge port 5. The scraper 3 can scrape the ceramic slurry above the equipment body 1 flat.

[0040] During this process, when the ceramic slurry flows out through the discharge port 5 inside the casting box 2, it will pass through the filter screen 6. The filter screen 6 filters the agglomerated part of the ceramic slurry, so that the agglomerated slurry will not fall into the equipment body 1. The feed pipe 28 is in contact with the upper surface of the equipment body 1. The feed pipe 28 opens in the direction of the scraper 3, and the electric push rod 29 is connected to the external power supply. The electric push rod 29 drives the feed pipe 28 to move left and right under the casting box 2 through the plate 30, so that when the ceramic slurry flowing out of the discharge port 5 falls on the top of the equipment body 1, the feed pipe 28 can allow the ceramic slurry to be more evenly applied to the equipment body 1, which is beneficial to improving the effect of ceramic casting.

[0041] At the same time, the plate 30 drives the cross plate 21 to move, and the cross plate 21 can drive the slider 19 to reciprocate inside the slide groove 20 along the length direction of the slide groove 20, and the slider 19 drives the connecting rod 18 to move inside the movable groove 17, thereby driving the No. 1 support plate 11 to rotate around the cross bar 10. When the slider 19 and the connecting rod 18 move to the left, the No. 1 rolling piece 12 can be driven to swing to the right through the No. 1 support plate 11. At this time, under the action of the No. 2 support plate 13, the cross plate 21 pushes the No. 2 rolling piece 14 to swing left around the cross bar 10 through the push plate 23. When the connecting rod 18 rotates to the right, the No. 1 rolling piece 12 swings to the left. At this time, the No. 2 rolling piece 14 swings to the right, and the No. 1 rolling piece 12 and the No. 2 rolling piece 14 swing alternately, so that the ceramic raw material between the No. 1 rolling piece 12 and the No. 2 rolling piece 14 can be kneaded to separate the agglomerated raw pulp. Under the action of the blade 15, the separation efficiency of the agglomerated raw pulp can be improved.

[0042] At the same time, the No. 1 rolling piece 12 and the No. 2 rolling piece 14 can contact the filter 6 when swinging, and squeeze the filter 6 to move downward. The filter 6 drives the mounting frame 7 to slide downward along the column 8. At this time, the spring 9 is deformed by the force. With the cooperation of the protrusion 16, the agglomerated pulp filtered above the filter 6 can be beaten to crush the pulp. At the same time, it can prevent the agglomerated pulp from clogging the filter holes opened on the filter 6, which is beneficial to ensure the filtering effect of the filter 6. When the No. 1 rolling piece 12 and the No. 2 rolling piece 14 are separated from the filter 6, the filter 6 can be driven to reset upward under the elastic force of the spring 9.

[0043] Furthermore, the No. 1 rolling piece 12 and the No. 2 rolling piece 14 can drive the guide block 26 to move synchronously when swinging. Under the action of the adjusting plate 24, the guide block 26 slides inside the guide groove 25, thereby driving the No. 1 support plate 11 to slide inside the groove 27. At the same time, the No. 2 support plate 13 can slide inside another group of grooves 27. The No. 1 rolling piece 12 and the No. 2 rolling piece 14 approach or move away from each other, squeezing the agglomerated pulp, which is beneficial to further improve the crushing effect of the agglomerated pulp.
