[0025] In this embodiment, during the rotation of the conveyor belt 23, the transmission through hole 24 on the conveyor belt 23 moves accordingly. As the transmission through hole 24 moves, the two first transmission gears 21 and the two second transmission gears 27 are driven to rotate. During the rotation of the two first transmission gears 21, the two driven gears 20 are driven to rotate. During the rotation of the two driven gears 20, one of the squeezing rollers 19 is driven to rotate. As one of the squeezing rollers 19 rotates, the auxiliary gear 22 rotates and drives the other squeezing roller 19 to rotate. The rotation of the two second transmission gears 27 can drive the crushing roller 26 to rotate. By setting two An extrusion roller 19 can extrude the molten material into a molten plate. By setting the first transmission gear 21 and the second transmission gear 27, the extrusion roller 19 and the crushing roller 26 can be driven to rotate during the operation of the conveyor belt 23.

[0026] Embodiment 3 according to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a cooling chamber 29 is fixedly installed at the top of the processing table 1 and near the middle position, and two fixed boxes 30 are installed through the top of the cooling chamber 29. Fans 33 are fixedly installed inside the two fixed boxes 30. A fixed groove 31 is opened on one side of the two fixed boxes 30. Filter plates 32 are inserted into the two fixed grooves 31. The internal size of the fixed groove 31 is the same as that of the filter plate 32. A handle 34 is fixedly installed on one side of the two filter plates 32.

[0027] In this embodiment, when the molten plate enters the cooling chamber 29, the fan 33 in the fixed box 30 applies continuous flowing air to the molten plate. The flowing air quickly takes away the heat of the molten plate, so that the molten plate is quickly cooled. By setting the filter plate 32, dust in the air can be effectively prevented from falling onto the molten plate. By setting the handle 34, the extraction and installation of the filter plate 32 can be facilitated.

[0028] The use method and working principle of the device are as follows: the staff starts the conveyor belt 23. During the rotation of the conveyor belt 23, the transmission through hole 24 on the conveyor belt 23 moves along. As the transmission through hole 24 moves, the two first transmission gears 21 and the two second transmission gears 27 are driven to rotate. During the rotation of the two first transmission gears 21, the two driven gears 20 are driven to rotate. During the rotation of the two driven gears 20, one of the squeezing rollers 19 is driven to rotate. As one of the squeezing rollers 19 rotates, the auxiliary gear 22 rotates and drives the other squeezing roller 19 to rotate. The rotation of the two second transmission gears 27 can drive the crushing roller 26 to rotate. The molten material is squeezed by the two squeezing rollers 19 to become a plate-shaped molten plate, which falls onto the conveyor belt 23 and moves under the action of the conveyor belt 23. After entering between the two guide plates 3, its edge is squeezed toward the middle and continues to move, so that the molten plate becomes a regular shape and is flattened by the roller 9 in the subsequent movement. The flattening treatment is performed so that the molten plate becomes a molten plate of regular shape and equal thickness after leaving the guide plate 3. When the molten plate enters the cooling chamber 29, the fan 33 in the fixed box 30 applies continuous flowing air to the molten plate. The flowing air quickly takes away the heat of the molten plate, so that the molten plate is quickly cooled. The cooled material plate enters under the crushing roller 26 driven by the conveyor belt 23 and is crushed under the rotation of the crushing roller 26. The material particles after the processing are collected under the guidance of the guide plate 28 and subsequently crushed. When the thickness of the molten plate needs to be changed, the fixed sleeve 15 is moved to separate the fixed sleeve 15 from the fixed cylinder 14, and then the adjusting cap 17 is rotated to control the adjustment rod 5 to rotate. The adjusting rod 5 drives the adjusting gear 6 to rotate during the rotation, and drives the adjusting tooth plate 7 to move up and down during the rotation of the adjusting gear 6, thereby controlling the first mounting plate 8 to move up and down, thereby realizing the adjustment of the height of the flattening roller 9 from the conveyor belt 23, thereby achieving the purpose of controlling the thickness of the molten plate.
