[0040] Working principle: When the device starts working, the zinc alloy raw material is first placed on the first conveyor belt 3. The first conveyor belt 3 transports the zinc alloy raw material to the inside of the rectangular frame 24 and the storage frame 31 through the fixed L-shaped plate 4. During this period, the transmission rod 12 needs to be driven by the motor 11 to rotate, and the transmission rod 12 drives the storage frame 31 to rotate, and aligns the opening of one of the storage frames 31 with the opening at the top of the circular frame 1. The motor 11 is stopped, and then the operator moves the elastic handle 34 upwards, and the elastic handle 34 drives the movable plate 32 to move upwards. The movable plate 32 drives the spring 8 to stretch, and the movable plate 32 drives the sealing plug 37 to move upwards through the elastic rope 36. The elastic plate 38 will limit the moving distance of the sealing plug 37, which is convenient for zinc The alloy raw material is transported to the inside of the rectangular frame 24 and the storage frame 31. After the zinc alloy raw material is currently placed in the rectangular frame 24 and the storage frame 31, water is poured into the rectangular frame 24 and the storage frame 31 containing the zinc alloy raw material. The operator loosens the elastic handle 34, and the elasticity of the spring 8 drives the movable plate 32 to move to the initial position. The movable plate 32 is sealed with the inside of the rectangular frame 24 through the sealing ring 10, and the rectangular frame 24 and the storage frame 31 are connected by the connecting rod 42 and the convex plate 43. The first magnet strip 35 and the second magnet strip 41 connect the rectangular frame 24 and the storage frame 31, and then the motor 11 is started. The motor 11 drives the storage frame 31 to rotate through the transmission rod 12, and the above operation is repeated to transfer the zinc alloy raw material and Water is poured into the adjacent storage frames 31 and rectangular frames 24. When the three storage frames 31 and rectangular frames 24 are all filled with zinc alloy raw materials, the first conveyor belt 3 will no longer be placed with zinc alloy raw materials. The zinc alloy die-castings will be placed on the first conveyor belt 3, and the zinc alloy die-castings will be placed in turn on the adjacent fixed L-shaped plates 4. The first conveyor belt 3 drives the zinc alloy die-castings to be transported through the fixed L-shaped plates 4. During this period, the motor 11 is started, the motor 11 drives the transmission rod 12 to rotate, and the transmission rod 12 drives the storage frame 31 to rotate, and the first grinding plate 25, the second grinding plate 26 and the third grinding plate 30 are aligned with the opening at the top of the circular frame 1, and the zinc alloy die-castings will enter the adjacent first grinding plate 25, the second grinding plate 2 6 and the third grinding plate 30, when the zinc alloy die-casting is placed, the first conveyor belt 3 is closed, and the upper electric telescopic rod 15 is started.

The upper baffle 19 will block the opening at the top of the circular frame 1 and close the upper electric telescopic rod 15, and then start the motor 11, the motor 11 drives the transmission rod 12 to rotate, the transmission rod 12 drives the storage frame 31 to rotate, the storage frame 31 drives the rectangular frame 24 to rotate through the connecting rod 42 and the convex plate 43, and the storage frame 31 drives the first grinding plate 25 and the second grinding plate 26 to rotate through the support rod 27.The first grinding plate 25 drives the supporting plate 28, the fixing column 29 and the third grinding plate 30 to rotate, and the zinc alloy die-casting between the first grinding plate 25, the second grinding plate 26 and the third grinding plate 30 will move during the rotation, and the surface of the zinc alloy die-casting will contact the first grinding plate 25, the second grinding plate 26, the third grinding plate 30 and the arc-shaped grinding plate 23 respectively, so as to comprehensively grind the surface of the zinc alloy die-casting, and the zinc alloy raw material inside the rectangular frame 24 and the storage frame 31 will be fully in contact with water during the rotation, and the water will clean the zinc alloy raw material, so as to facilitate subsequent processing. When the device completes the processing of the zinc alloy raw material and the zinc alloy die-casting, it is necessary to drain the water inside the storage frame 31 and the rectangular frame 24 first, and first start the upper electric telescopic rod 15, and the upper electric telescopic rod 15 drives the upper through the connecting plate 17, the arc plate 18 and the fixing rod 16 The baffle 19 moves, and the upper baffle 19 moves away from the opening at the top of the round frame 1. The motor 11 rotates the storage frame 31 and the rectangular frame 24 to the opening at the top of the round frame 1. The operator takes out one of the limit plugs 44 at the rear end of the transmission rod 12 and moves the movable plate 32 upward. The movable plate 32 drives the sealing plug 37 to move through the elastic rope 36. The water inside the rectangular frame 24 and the storage frame 31 will flow out through the holes on the storage frame 31 and the transmission rod 12. The filter screen 40 prevents the zinc alloy raw material from flowing out with the water. Then the electric telescopic rod 15 below is started. The electric telescopic rod 15 below drives the lower baffle 19 to move through the connecting plate 17, the arc plate 18 and the fixed rod 16.
