[0035] In this embodiment, when the packaged plastic bags need to be inspected during the conveying process, the controller 114 is first opened, and the distance threshold (the distance between the detection end of the distance sensor 214 and the top of the conveying belt 112) is set according to the actual situation, and the packaged plastic bag seal qualified photos (i.e. the photos of the packaged plastic bag seal) are stored in the storage module. Then, the defective product box is placed directly below the discharge hole 221, and then the distance sensor 214 is started by the controller 114. The distance sensor 214 started in cooperation with the mounting plate 213 measures the distance between the detection end and the top of the conveying belt 112, and transmits the measured distance data to the controller 114 in the form of an electrical signal. The controller 114 compares the received distance data with the previously set distance threshold. When the received distance data of the controller 114 is the same as the previously set distance threshold, the controller 114 does not start the servo cylinder 202. When the received distance data of the controller 114 is different from the previously set distance threshold (i.e. there is a packaged plastic bag passing directly below the distance sensor 214), the controller 114 directly starts the servo cylinder 202. The servo cylinder 202 started in cooperation with the U-shaped frame 201 and the frame 203 drives the first servo motor 206, the vacuum pump 208, the counterweight 207 and the mounting plate 213 to vertically move downward. The first servo motor 206 vertically moving downward drives the suction cup 209, the first electric valve 210 and the second electric valve 211 to vertically move downward. When the suction cup 209 vertically moves downward, the controller 114 directly starts the vacuum pump 208, the first electric valve 210 and the industrial camera 205. The vacuum pump 208 started in cooperation with the frame 203, the hose 212 and the started first electric valve 210 extracts the air in the suction cup 209. When the continuously moving downward suction cup 209 contacts the packaged plastic bag passing directly below, the continuously moving downward suction cup 209 with the air extracted inside will suck the packaged plastic bag. Then, the controller 114 drives the sucked packaged plastic bag to vertically move upward in cooperation with the servo cylinder 202 and the above-mentioned components. Then, the controller 114 closes the first electric valve 210 and then closes the vacuum pump 208. When the packaged plastic bag vertically moves upward and cannot move any more, the controller 114 directly closes the servo cylinder 202, and the industrial camera 205 started in cooperation with the rectangular hole 204 takes a photo of one side of the seal of the packaged plastic bag, and transmits the taken seal photo to the controller 114 in the form of an electrical signal. The controller 114 compares the received seal photo with the previously stored seal qualified photo. When the received photo of the controller 114 is different from the previously stored seal qualified photo (i.e. it means that the seal of the packaged plastic bag is unqualified), the controller 114 starts the servo cylinder 202.The plastic bag is sucked and packaged, and then the controller 114 starts the second electric valve 211, and the second electric valve 211 is matched with the suction cup 209 to put down the packaged plastic bag, and then the controller 114 starts the servo electric cylinder 202 and the second servo motor 216, and the servo electric cylinder 202 is matched with the above-mentioned components to drive the suction cup 209 to move vertically upward, and the second servo motor 216 is matched with the double-hole frame 215 to drive the threaded rod 217 to rotate, and the threaded rod 217 is matched with the round rod 218 and the sliding plate 219 to drive the rubber strip 220 to move horizontally, and at the same time, the horizontally moving rubber strip 220 and the sliding plate 219 are matched with the discharge hole 221 to discharge the packaged plastic bag from the conveying mechanism 1 and drop it into the defective product box, and when the photo received by the controller 114 is the same as the stored sealing qualified photo (i.e. the packaged plastic bag is sealing qualified), the controller 114 starts the first servo motor 206, and the first servo motor 206 is matched with the frame 203 and the suction cup 209 to drive the packaged plastic bag to rotate 180 degrees, and then the industrial camera 205 takes a photo of the other sealing of the packaged plastic bag and transmits the photo to the controller 114, and when the other sealing of the packaged plastic bag is qualified (i.e. both sealings of the packaged plastic bag are qualified), the controller 114 uses the cooperation of the above-mentioned components to put down the packaged plastic bag without starting the second servo motor 216, and when the other sealing of the packaged plastic bag is unqualified, the controller 114 operates according to the above-mentioned operation steps to discharge the packaged plastic bag into the defective product box, i.e. the quality inspection of the packaged plastic bag is completed, and then the operation according to the operation steps is performed.

[0038] The whole mechanism achieves the following effects and working principles:

[0039] In the preparation stage, the controller 114 is first connected with the external power supply, then the controller 114 is connected with the driver 115, then the driving motor 113 is connected with the controller 114, then the two electric push rods 107 are both connected with the controller 114, then the servo electric cylinder 202 is connected with the controller 114, then the industrial camera 205 is connected with the controller 114, then the first servo motor 206 and the second servo motor 216 are both connected with the controller 114, then the first electric valve 210 is connected with the controller 114, and finally the second electric valve 211 is connected with the controller 114;

[0040] The conveying stage, when the packaged plastic bag needs to be conveyed, at this time the conveying mechanism 1 is first moved to the appropriate position, then the height of the first flat plate 101, the second flat plate 102 and each rectangular plate 116 is adjusted by the cooperation of the two sets of supporting legs 103 and the two supporting frames 104, then the tension of the conveyor belt 112 is adjusted according to the actual situation, when the conveyor belt 112 is too tight, at this time the two electric push rods 107 are started at the same time by the cooperation of the controller 114 and the driver 115, at this time the two electric push rods 107 started at the same time will drive the two hole blocks 108 to move horizontally in the two sliding holes 105 respectively under the cooperation of the two installation grooves 106, and the two hole blocks 108 moving horizontally will drive the first transmission roller 110 to move horizontally, and the first transmission roller 110 moving horizontally will reduce the tension of the conveyor belt 112 under the cooperation of the second transmission roller 111, when the tension of the conveyor belt 112 reaches the normal use state, at this time the two electric push rods 107 are closed at the same time by the cooperation of the controller 114 and the driver 115, when the conveyor belt 112 is too loose, at this time the two electric push rods 107 are started at the same time by the cooperation of the controller 114 and the driver 115, at this time the two electric push rods 107 started at the same time will drive the first transmission roller 110 to move horizontally away from the second transmission roller 111 under the cooperation of the two installation grooves 106, the two sliding holes 105 and the two hole blocks 108, and the first transmission roller 110 moving horizontally will increase the tension of the conveyor belt 112 under the cooperation of the second transmission roller 111, when the tension of the conveyor belt 112 reaches the normal use state, at this time the two electric push rods 107 are closed at the same time by the cooperation of the controller 114 and the driver 115, then the drive motor 113 is started by the controller 114, at this time the drive motor 113 started will drive the second transmission roller 111 to rotate under the cooperation of the first flat plate 101, the second flat plate 102 and the two cylindrical holes 109, and the second transmission roller 111 rotating will drive the conveyor belt 112 to transmit under the cooperation of the first transmission roller 110 and the two hole blocks 108, then the packaged plastic bag is placed on the conveyor belt 112 in transmission, at this time the packaged plastic bag can be conveyed under the cooperation of the conveyor belt 112 in transmission;

[0041] When the quality inspection phase needs to be carried out on the packaged plastic bags in the conveying process, the controller 114 is opened first, and the distance threshold value (the distance between the detection end of the distance measuring sensor 214 and the top of the conveying belt 112) is set according to the actual situation, and the packaged plastic bag seal qualified photos (i.e. the photos of the packaged plastic bag seal) are stored in the storage module, then the defective product box is placed directly below the discharge hole 221, and then the controller 114 starts the distance measuring sensor 214, which measures the distance between the detection end and the top of the conveying belt 112 with the cooperation of the mounting plate 213, and transmits the measured distance data to the controller 114 in the form of an electrical signal.

The vacuum pump 208 is started in cooperation with the frame 203, hose 212 and first electric valve 210, and the air in the suction cup 209 is pumped out, and when the suction cup 209 continues to move downward and contacts the packaged plastic bag passing directly below, the suction cup 209 continues to move downward and absorbs the packaged plastic bag. The controller 114 drives the suction cup 209 to move vertically upward with the cooperation of the servo electric cylinder 202 and the above-mentioned components, and then the controller 114 closes the first electric valve 210 and then closes the vacuum pump 208. When the packaged plastic bag moves vertically upward and cannot move any more, the controller 114 directly closes the servo electric cylinder 202, and the industrial camera 205 is started to take a photo of one side of the seal of the packaged plastic bag with the cooperation of the rectangular hole 204, and transmits the taken seal photo to the controller 114 in the form of an electrical signal. The controller 114 compares the received seal photo with the previously stored seal qualified photo, and when the received photo is different from the previously stored seal qualified photo (i.e. the seal of the packaged plastic bag is unqualified), the controller 114 starts the servo electric cylinder 202,The plastic bag is sucked and packaged vertically downward until it contacts the conveyor belt 112, and then the controller 114 first starts the second electric valve 211, which is started in cooperation with the suction cup 209 to lower the sucked and packaged plastic bag, and then the controller 114 first starts the servo electric cylinder 202 and then starts the second servo motor 216, which is started in cooperation with the double-hole frame 215 to drive the threaded rod 217 to rotate, and the rotating threaded rod 217 is in cooperation with the round rod 218 and the sliding plate 219 to drive the rubber strip 220 to move horizontally, and at the same time, the horizontally moving rubber strip 220 and sliding plate 219 are in cooperation with the discharge hole 221 to discharge the lowered packaged plastic bag from the conveying mechanism 1 and fall into the scrap box, and when the controller 114 receives the photo and the pre-stored sealing qualified photo are the same (i.e. the packaged plastic bag sealing is qualified), the controller 114 starts the first servo motor 206, which is started in cooperation with the frame 203 and the suction cup 209 to rotate the sucked and packaged plastic bag until it rotates 180 degrees, and then the industrial camera 205 takes a photo of the other sealing of the above-mentioned packaged plastic bag and transmits the taken photo to the controller 114, when the other sealing of the packaged plastic bag is qualified (i.e. the two sealings of the packaged plastic bag are qualified), the controller 114 uses the cooperation of the above-mentioned components to lower the packaged plastic bag, and does not start the second servo motor 216, when the other sealing of the packaged plastic bag is unqualified, the controller 114 operates according to the above-mentioned operation steps to discharge the packaged plastic bag into the scrap box, i.e. the quality inspection operation of the packaged plastic bag is completed, and then the operation according to the operation steps can be performed.

[0042] Wherein, the output end of the first servo motor 206 is reversed to reset to the initial state after completing a rotation operation and before affecting the next quality inspection of the packaged plastic bag (i.e. without affecting the use of the hose 212).
