[0022] like Figure 2 As shown: the flip mechanism 2 includes a frame 201, a lifting frame 202, a movable clamping arm 203, a lifting mechanism 204, a clamping cylinder 205, a rotating motor 206, a worm reducer 207, a tray clamp 208 and a photoelectric sensor 209. The frame 201 includes two columns 2011 and a beam 2012 fixedly arranged between the two columns 2011. The columns 2011 are fixedly arranged on both sides of the conveyor line 1. The frame 201 is used to support other structures. The beam 2012 is placed above the conveyor line 1. The lifting mechanism 204 is fixedly arranged on the beam 2012. The lifting mechanism 204 includes a lifting cylinder 2041, a guide rod 2042 and a guide sleeve 2043. The lifting mechanism 204 is vertically fixedly installed on the beam 2012 of the frame 201. Cylinder 2041, the fixed end of the lifting cylinder 2041 is fixedly connected to the crossbeam 2012, the telescopic end of the lifting cylinder 2041 is fixedly connected to the horizontal part 2021 of the lifting frame 202, and two guide sleeves 2043 are fixedly installed on the crossbeam 2012. The two guide sleeves 2043 are respectively installed on both sides of the lifting cylinder 2041. A guide rod 2042 is provided in the sliding sleeve 2043. One end of the guide rod 2042 is fixedly connected to the horizontal part 2021 of the lifting frame 202. The sliding direction of the guide rod 2042 in the guide sleeve 2043 is parallel to the telescopic direction of the lifting cylinder 2041, which can keep the lifting frame 202 stable when moving up and down to reduce shaking. The telescopic movement of the lifting cylinder 2041 drives the lifting frame 202 to move up and down.

[0023] like Figure 3As shown: a sliding sleeve 2031 is fixedly provided on the movable clamping arm 203, and the sliding sleeve 2031 is slidably mounted on the horizontal part 2021 of the lifting frame 202, and two rollers 2032 are installed on the sliding sleeve 2031, and a roller sleeve 2033 is rotatably mounted on the roller 2032, and the roller sleeve 2033 is in rolling contact with the top surface of the horizontal part 2021, and the top end of the movable clamping arm 203 is in sliding contact with the bottom surface of the horizontal part 2021, and the movable clamping arm 203 can move laterally along the horizontal part 2021 and maintain a certain verticality with the horizontal part 2021, thereby stably clamping the tray 4.

[0024] The lifting frame 202 includes a horizontal portion 2021 and a fixed clamping arm 2022 vertically arranged with the horizontal portion 2021. The lifting mechanism 204 is connected to the horizontal portion 2021 of the lifting frame 202. The fixed clamping arm 2022 is placed at one end of the horizontal portion 2021. A movable clamping arm 203 is movably sleeved at the other end of the horizontal portion 2021. A clamping cylinder 205 is horizontally installed on the horizontal portion 2021. The fixed end of the clamping cylinder 205 is fixedly connected with the horizontal portion 2021. The telescopic end of the clamping cylinder 205 is fixedly connected with the movable clamping arm 203. When the clamping cylinder 205 is extended, the movable clamping arm 203 opens outward. When the clamping cylinder 205 is shortened, the movable clamping arm 203 is clamped inward. The fixed clamping arm 2022 is close to one side of the pallet 4 on the conveyor line 1, and the movable clamping arm 203 can move laterally along the horizontal portion 2021. The other side of the pallet 4 on the clamping conveyor line 1 is clamped by controlling the telescopic driving movable clamping arm 203 of the clamping cylinder 205, and the movable clamping arm 203 and the fixed clamping arm 2022 are used to clamp the two sides of the pallet 4 to clamp the pallet 4. At the same time, a photoelectric sensor 209 is fixedly installed on the conveying line 1, and a photoelectric sensor 209 is fixedly installed on one side of the column 2011. The specific photoelectric sensor 209 can be installed on any side of the column 2011. The photoelectric sensor 209 can sense the pallet 4. During implementation, the photoelectric sensor 209 is electrically connected to the PLC, and the PLC controls the actions of the clamping cylinder 205 and the lifting cylinder 2041 according to the signal detected by the photoelectric sensor 209. The control method and PLC circuit connection are both existing technologies known to those skilled in the art, so they are not repeated here.

[0025] like Figure 4As shown: a worm reducer 207 and a rotary motor 206 are fixedly installed at the lower ends of the fixed clamp arm 2022 and the movable clamp arm 203, respectively. The output shaft of the rotary motor 206 is connected to the input shaft of the worm reducer 207, and the output end of the worm reducer 207 is connected to the tray clamp 208. The chuck 2081 of the tray clamp 208 is placed on the inner side between the fixed clamp arm 2022 and the movable clamp arm 203. The tray clamp 208 includes a chuck 2081, a rotating shaft 2082, a sensor block 2083 and a proximity switch 208. 4, one end of the rotating shaft 2082 is fixedly connected to the clamping plate 2081, the rotating shaft 2082 of one tray clamp 208 passes through the fixed clamping arm 2022 and is connected to the output end of the worm reducer 207 fixedly installed on the fixed clamping arm 2022, and the rotating shaft 2082 of the other tray clamp 208 passes through the movable clamping arm 203 and is connected to the output end of the worm reducer 207 fixedly installed on the movable clamping arm 203. The movable clamping arm 203 contracts and clamps the tray 4, relying on the tray placed on the fixed clamping arm 2022 and the movable clamping arm 203. The clamps 208 clamp the two sides of the pallet 4. After clamping the pallet 4, when the lifting mechanism 204 lifts the lifting frame 202 to make the pallet 4 leave the conveyor line 1, the rotating motor 206 drives the two pallet clamps 208 to rotate synchronously through the worm reducer 207, driving the pallet 4 to flip; the rotating shaft 2082 passes through the output end of the worm reducer 207, and a sensing block 2083 is fixedly sleeved. Two proximity switches 2084 are fixedly installed on the worm reducer 207. The two proximity switches 2084 are arranged relatively around the rotating shaft 2082. The proximity switch 2084 detects the rotation angle of the rotating shaft 2082 by detecting the sensing block 2083. The rotation angle of the rotating shaft 2082 is the rotation angle of the tray 4 clamped by the tray clamp 208. The two proximity switches 2084 are arranged relatively around the rotating shaft 2082. The sensing block 2083 on the rotating shaft 2082 rotates 180° around the rotating shaft 2082 to switch between the two proximity switches 2084. The proximity switch 2084 is electrically connected to the PLC, and the PLC detects and controls the rotation angle of the tray 4 through the proximity switch 2084.

[0026] Working principle: the pallets 4 transported from the outdoor storage area are placed on the conveyor line 1 at intervals in sequence. The conveyor line 1 transports the pallets 4 forward. When passing through the first flipping mechanism 2, the pallet 4 moves to the position of the photoelectric sensor 209 of the first flipping mechanism 2. The photoelectric sensor 209 triggers the transmission of an electrical signal to the PLC to start the flipping program. The PLC first controls the movable clamping arm 203 to contract and clamp the pallet 4. Then the lifting cylinder 2041 drives the lifting frame 202 to rise, lifts the pallet 4 away from the conveyor line 1, and raises it a certain distance so that the pallet 4 does not interfere with the conveyor line 1 when it is flipped. After rising into place, the PLC controls the rotating motor 206 to start. The two rotating motors 206 rotate synchronously to drive the pallet clamp 208 to rotate. During rotation, the induction block 2083 set on the rotating shaft 2082 moves from one proximity switch 2084 to another proximity switch 2084. When the second proximity switch 2084 is triggered, it indicates that the tray 4 has been flipped 180°. At this time, the PLC controls the rotating motor 206 to stop, and the PLC controls the lifting cylinder 2041 to descend. After it descends into place, it controls the movable clamping arm 203 to release the tray 4, that is, the first flipping of the tray 4 is completed. The flipped tray 4 continues to be conveyed forward along the conveyor line 1 to invert the accumulated water and drain it. When passing through the cleaning mechanism 3, the rotating roller brush 301 brushes off the surface pollutants, adhered dust, broken paper packaging, etc., and then it is transported to the second flipping mechanism 2 by the conveyor line 1. Similarly, after the photoelectric sensor 209 of the second flipping mechanism 2 senses that the tray 4 is in place, it performs another flipping action. Its overall control method and action logic are the same as those of the first flipping mechanism 2. At this time, the tray 4 is flipped again and placed upward for use in the subsequent packaging process.
