[0061] When the fourth motor 702 rotates, the first-layer turntable 704, the second-layer turntable 706 and the supporting column rotate together, and a transparent glass door is formed on one side of the mounting frame 701.

[0062] The sealing member 8 includes a support frame 801, a first swing roller 802, a second swing roller 803 and a third swing roller 804.

[0066] The blanking box 6 will have an arc during the rotation process. Since the diameter of the third swing roller 804 is larger than the diameter of the blanking box 6, the top surface of the blanking box 6 can be sealed during the rotation.

[0067] Working principle: When the first motor 102 drives the conveyor belt 101 to rotate, the waste on the conveyor belt 101 falls into the cavity 201 along the path of the conveyor belt 101. At this time, the waste with a small area will fall from the circulation space into the active chamber 403, and the waste with a large area will fall on the cutting knife 203 on the support plate 202. The first cylinder 302 pushes the lower pressure plate 303, which first contacts the waste and then squeezes the waste towards the cutting knife 203, so that the large area of ​​waste is cut. The cut waste also falls from the circulation space into the active chamber 403.

[0068] The waste material that falls into the movable chamber 403 is pushed by the second cylinder 404 to push the push plate 405, which carries the waste material to the first roller 408 and the second roller 409. At this time, the second motor 406 drives the first roller 408, and the third motor 407 drives the second roller 409. The first roller 408 and the second roller 409 both rotate, and the waste material enters from one end of the moving space. The extrusion blocks on the first roller 408 and the second roller 409 crush the waste material. Finally, the waste material is transferred out from the other end of the moving space according to the rotation direction of the first roller 408 and the second roller 409.

[0069] Since the connection between the movable chamber 403 and the receiving chamber 503 is inclined, the waste after secondary crushing can fall into the receiving chamber 503 along the inclined path. Small-sized waste will pass through the receiving chamber 503 and the through hole 507 and fall into the receiving groove 601.

[0070] The third cylinder 504 pushes the pressing plate 506, which extends into the through slot. The fourth cylinder 505 moves the third cylinder 504 up and down, so that the pressing plate 506 can compress the waste. The waste is squeezed into the through hole 507 and finally falls into the plastic bag on the receiving slot 601. When the plastic bag is filled with a certain amount of waste, the fourth motor 702 is driven, and the first and second turntables 704 and 706 rotate, which can drive the movement of the discharge box 6 to discharge the waste in the plastic bag.

[0071] During the movement, the two fifth motors 805 simultaneously drive the first swing roller 802 and the second swing roller 803 to rotate, so that the sealing belt rotates on the outer walls of the first swing roller 802, the second swing roller 803 and the third swing roller 804, and the sealing belt on the third swing roller 804 seals the plastic bags in the discharge box 6 to complete the packaging. After completion, the fifth cylinder 703 pushes the connecting plate 705 and pushes the discharge box 6 upward, so that the discharge box 6 can be taken out, realizing the integration of loading, crushing, compression, discharge and packaging, which can improve the crushing quality and crushing efficiency.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
