Embodiment 3

(19) The central control display 1 is started after connecting to the power supply, trigger the first infrared sensor 201 by the hand or an object, after the first infrared sensor 201 receiving the signal, the central control display 1 records the weight of the garbage in the compression and hot-melting bin 3 as G0, at the same time, controls the first motor 203 to open the induction rotating cover 202 and last for 5 s, then put garbage into the garbage putting bin 2.

(20) During the garbage entering the hydraulic bin 301, a signal is sent to the central control display 1 by the second infrared sensor 204 in the garbage putting bin 2 after sensing the passage of the garbage, the central control display 1 counts up by 1, and reads the readings of the electronic scale 306 and records it as G1.

(21) The second motor 304 is started, and the second motor 304 controls the compression plate 302 to reciprocate by controlling the hydraulic cylinder 303. After a compression is completed, the central control display 1 reads the readings of the electronic scale 306 and records it as G2.

(22) The ratio of mass change before and after compression x=(G1?G2)/(G1?G0), if x=7%, which is greater than the preset value x0, such as x0=5%, it is determined that the recently put garbage is mixed with large amount of wet garbage, and the garbage classification is not standardized, an alarm of the non-standard garbage classification is further sent out by the central control display 1. A water storage pipe and a drainage valve are communicate with the bottom of the compression and hot-melting bin 3, after receiving the alarm, the drainage valve is opened to drain out the liquid compressed out from the wet garbage mixed in; under normal circumstances, the garbage classification is standardized, since the system is mainly for dry garbage collection and processing, there is no need to open the drain valve.

(23) Continue to put garbage, and compress the garbage by the hydraulic cylinder 303. When the garbage put in reaches a predetermined number, such as 6 times, or the level transducer 309 detects that the garbage reaches the set level height, the central control display 1 activates the electrically heated coils 305 to start heating. When the temperature of the electrically heated coil 305 reaches a predetermined temperature, such as 160? C., the garbage bag in the hydraulic bin 301 undergoes hot-melting and shrinkage, and the garbage in the garbage bag is maintained in a compressed state without rebounding. the central control display 1 controls the third motor 308 to open the first discharge valve 307, so that the garbage enters the packing bin 4 from the compression and hot-melting bin 3, and the count of the garbage bags put in is cleared.

(24) In the packing bin 4, the packing bag 411 is extended from the bag box 401, and laid in the vacuum chamber 412, so that the garbage bags (that is compressed garbage and melted garbage bags) from the compression and hot-melting bin 3 are directly wrapped by the packing bag 411. the vacuum pump 413 is controlled to rotate reversely to inflate the vacuum chamber 412, at this time, the gap between the packing bag 411 with garbage and the vacuum chamber 412 is enlarged, and the air in the packing bag 411 is squeezed out, so that the packing bag 411 more densely wraps the garbage inside. If the vacuum pump 413 provides too much gas and the pressure is too high, the decompression valve 417 is opened to prevent the packing bag 411 extending from the bag box 401 from being displaced or broken.

(25) Start the packing machine 402 to pack the compressed garbage, the fourth motor 408 and the sixth motor 410 are controlled by the central control display 1 to respectively drive the first pushing rod 403 and the second pushing rod 407 to move horizontally perpendicular to each other at different heights, so as to tighten the packing bag 411, and finally the packing bag 411 is closed at a fixed corner, during this process, the vacuum pump 413 continually to inflate to ensure the excess air in the packing bag 411 is squeezed out.

(26) The vacuum pump 413 stops working.

(27) Subsequently, the first heating wire 404 and the second heating wire 406 simultaneously heats and melts the fixed corner, then the fifth motor 409 is started to drive the cutter 405 between the first heating wire 404 and the second heating wire 406 to cut the closed position, the garbage packing is completed.

(28) The central control display 1 controls the seventh motor 416 to start operation, the second discharge valve 414 is opened and the packing bag 411 containing compressed garbage falls on the lifting platform 501 located in the forwarding bin 5.

(29) The central control display 1 controls the vacuum pump 413 to rotate forward, the vacuum chamber 412 is vacuumized, so that the packing bag in the bag box 401 is sucked into the vacuum chamber 412 and clings to the inner wall of the vacuum chamber 412, thereby completing laying the packing bag for the next garbage packing.

(30) At the same time, the eighth motor 506 is started, the chain 504 is driven by the gear 503 to rotate a full turn, the chain connecting rod 502 moves synchronously with the chain 504. When the chain connecting rod 502 moves from bottom to top, it drives the sliding groove 507 to drive the lifting platform 501 to move upward; when the chain connecting rod 502 located upward moves from left to right, the lifting platform 501 does not move, the chain connecting rod 502 only moves in the sliding groove 507 from left to right, which pushes the packing bag 411 located on the lifting platform 501 to move from left to right and fall into the garbage can 7; when the chain connecting rod 502 moves from top to bottom, it drives the sliding groove 507 to drive the lifting platform 501 to move downward; when the chain connecting rod 502 located downward moves from right to left, the lifting platform 501 does not move, the chain connecting rod 502 only moves horizontally in the sliding groove 507 of the lifting platform 501, at this point, the chain 504 has completed one turn, the chain connecting rod 502 and the lifting platform 501 both return to the original position and complete the transfer of the garbage on the lifting platform 501 to the garbage can 7.

(31) Finally, it should be noted that the above description is only some embodiments of the disclosure, and is not used to limit the disclosure. Although the disclosure is described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some of the technical features.
