When the cover plate 12 is opened, the linkage device 4 drives one end of the filter plate 13 close to the discharge port 11 to rotate towards the top of the collecting box 1, so that the air inlet and outlet pipeline 2 and the feeding pipeline 3 are positioned at the same side of the filter plate 13; when the cover plate 12 is closed, the linkage device 4 drives one end of the filter plate 13 close to the discharge port 11 to rotate towards the bottom of the collection box 1, so that the air inlet and outlet pipeline 2 and the feeding pipeline 3 are positioned at the upper side and the lower side of the filter plate 13.

The air supply device 8 is then activated to blow air so that the waste adhering to the filter plates 13 and the waste in the collection container 1 are blown out of the collection container 1 by the air flow from the discharge opening 11, avoiding the waste being blown into the feed conduit 3.
Referring to fig. 2, when the waste material is required to be collected, the power assembly 5 retracts to the output end thereof, and the linkage device 4 is driven to close the cover plate 12, the linkage device 4 drives one end of the filter plate 13 close to the discharge opening 11 to rotate towards the bottom of the collection box 1, so that the air inlet/outlet pipeline 2 and the feeding pipeline 3 are positioned at the upper side and the lower side of the filter plate 13, and then the air supply device 8 is started to suck air, so that the waste material enters the collection box 1 through the suction head 7 and the feeding pipeline 3. In this way, the waste material entering the collection box 1 is prevented from being sucked into the air supply device 8 through the air inlet and outlet pipeline 2.

In order to drive the connecting shaft 95 to move, the driving assembly 10 is further included, and one end of the connecting shaft 95 extends out of the air inlet 942 and is connected to the output end of the driving assembly 10.
In order to realize the switching among the positive pressure (blowing), negative pressure (suction) and normal pressure states of the feeding pipeline 3 and the air inlet and outlet pipeline 2 in the whole recovery system, the recovery system also comprises an air direction converter 9. Specifically, the driving assembly 10 can drive the connecting shaft 95 to perform a linear motion along the length direction of the inner cavity of the air-direction converter 9 through the output end thereof, so as to complete the contact sealing or separation between the first valve plate 96 and the air hole 911 and the air release hole 922 in the first chamber 92, and between the second valve plate 97 and the air hole 911 and the air inlet 942 in the third chamber 94. Wherein the driving assembly 10 may be selected as a cylinder.

The air flow enters the feeding pipe 3 along the suction opening of the suction head 7, flows through the collecting box 1, enters the second chamber 93 and the third chamber 94 from the transmission interface 931 along the air inlet and outlet pipe 2, enters the air supply device 8 through the air suction pipe 98 from the air outlet interface 941, flows out of the air supply device 8, enters the first chamber 92 along the air blowing pipe 99, and finally is discharged out of the converter 9 through the air discharge opening 922 to form a negative pressure loop (air suction state).
Referring to fig. 8, when the air needs to be blown, the output end of the driving assembly 10 drives the connecting shaft 95 to move towards the air release opening 922 in the first chamber 92, so that the first valve plate 96 contacts and seals the air release opening 922, and the second valve plate 97 contacts and seals the air hole 911 in the third chamber 94. The air flow enters the third chamber 94 from the air inlet 942, enters the air supply device 8 from the air outlet 941, then flows out of the air supply device 8, enters the first chamber 92 and the second chamber 93 along the air blowing pipe 99, and enters the air inlet/outlet pipe 2 through the transmission interface 931 to form a positive pressure loop (air blowing state). Wherein the arrows in fig. 7 and 8 indicate the air flow direction.
The working principle of the recovery system of the invention is as follows: when collecting waste materials, the power assembly 5 retracts to the output end thereof to drive the first rack 411 to move the closed cover plate 12, and the second rack 421 drives one end of the filter plate 13 close to the discharge port 11 to rotate towards the bottom of the collection box 1, so that the air inlet/outlet pipeline 2 and the feeding pipeline 3 are positioned at the upper side and the lower side of the filter plate 13. Then, the output end of the driving assembly 10 drives the connecting shaft 95 to move toward the air inlet 942 in the third chamber 94, so that the second valve plate 97 contacts and seals the air inlet 942, and simultaneously the first valve plate 96 contacts and seals the air hole 911 in the first chamber 92. Finally, the air supply device 8 is restarted, the air flow enters the feeding pipeline 3 along the suction port of the suction head 7, flows through the collection box 1, enters the second chamber 93 and the third chamber 94 from the transmission interface 931 along the air inlet and outlet pipeline 2, enters the air supply device 8 through the air suction pipeline 98 from the air outlet interface 941, flows out of the air supply device 8, enters the first chamber 92 along the air blowing pipeline 99, and finally discharges air out of the converter 9 through the air discharge port 922 to form a negative pressure loop (air suction state). Thus, under the influence of negative pressure, waste materials generated by the sealing and cutting station of the packaging bag are sucked into the collecting box 1 through the material suction head 7.
When the waste material is discharged, the power assembly 5 extends out of the output end thereof to drive the first rack 411 to move to open the cover plate 12, and the second rack 421 drives one end of the filter plate 13 close to the discharge opening 11 to rotate towards the top of the collection box 1, so that the air inlet/outlet pipeline 2 and the feeding pipeline 3 are positioned at the same side of the filter plate 13. Then, the output end of the driving assembly 10 drives the connecting shaft 95 to move toward the air release opening 922 in the first chamber 92, so that the first valve plate 96 contacts and seals the air release opening 922, and the second valve plate 97 contacts and seals the air hole 911 in the third chamber 94. Finally, the air supply device 8 is restarted, the air flow enters the third chamber 94 from the air inlet 942, enters the air supply device 8 from the air outlet interface 941, then flows out of the air supply device 8, enters the first chamber 92 and the second chamber 93 along the air blowing pipeline 99, and enters the air inlet/outlet pipeline 2 through the transmission interface 931 to form a positive pressure loop (air blowing state). In this way, the waste in the collection container 1 can be blown out of the collection container 1 through the discharge opening 11.
