[0010] Preferably, the packaging mechanism includes a belt conveyor mechanism three, rollers, a camera four, a hot-melt horizontal sealing assembly, a hot-melt vertical sealing assembly, a belt conveyor mechanism four, and a straight blade; both belt conveyor mechanism three and belt conveyor mechanism four are mounted on frame four, with the output end of belt conveyor mechanism three located at the input end of belt conveyor mechanism four. Guide plate two is fixed to frame four and located at the input end of belt conveyor mechanism three and the output end of belt conveyor mechanism two. Above belt conveyor mechanism three, frame four has two roller groups arranged at intervals along the conveying direction. Each roller group consists of two rollers arranged at intervals, and the two aligned rollers in the two roller groups are synchronously driven by drive assembly two.

[0011] The present invention discloses a leafy vegetable processing method using a multifunctional leafy vegetable processing device, which is as follows:

[0012] Connect the inlet of the water inlet pipe to the water storage tank via a water pump, and connect the outlet of the water outlet pipe to the collection tank via a solenoid valve. When the solenoid valve is closed, the water pump operates, drawing water from the storage tank through the inlet pipe, various delivery pipes, and each nozzle into the cleaning tank, filling it to a preset depth. The air pump delivers air to the cleaning tank through the main pipe and various exhaust pipes, creating bubbles in the water within the tank. Simultaneously, water from the storage tank is pumped to each nozzle and sprayed out. Place the two support frames on the ground and remove them for placement. The film roll is placed on the placement shaft, and limiting cylinders are placed at both ends of the film roll on the placement shaft. Then, the two ends of the placement shaft are placed in the U-shaped grooves opened on the two support frames. The two ends of the film roll are limited by the two limiting cylinders. The film roll is pulled out and covered on the guide plate two. Then, the two sides of the film are attached together and pass through the two roller gaps of one roller group, the two horizontal sealing heating aluminum block gaps of the hot melt horizontal sealing assembly, and the two roller gaps of another roller group in sequence, so that each roller group clamps the two sides of the attached film together.

[0013] Leafy greens are placed at preset time intervals at the input end of conveyor belt 1, with the roots of the greens facing the circular blades. Camera 1 identifies the cutting position of the green roots, and conveyor belt 1 starts working, transporting the greens to below the pressing block. Conveyor belt 1 then pauses to perform the cutting operation. After the cutting operation is completed, conveyor belt 1 resumes working, transporting the cut greens to below the scissor assembly. Translation mechanism 2 drives drive motor 2 to move the electric gripper along the direction perpendicular to the conveying direction of conveyor belt 1 and closer to the greens, so that the cut greens are positioned between the two gripping blocks of the electric gripper. Then, the yellowing leaf removal operation is performed. At the same time, new greens placed on conveyor belt 1 are transported... The vegetables are fed to the bottom of the pressing block for root cutting. With the intermittent conveying of conveyor belt one, each leafy vegetable on conveyor belt one completes root cutting and yellow leaf removal before being sent to the washing box for washing. After washing, they are sent to the draining board for draining, and then sent to conveyor belt two. When the weighing device detects that the total weight of the leafy vegetables on conveyor belt two exceeds the preset weight, conveyor belt two operates for a preset time, conveying these leafy vegetables into the film on guide plate two. Some leafy vegetables are located within the film attached to both sides of conveyor belt three, and then they are packaged into sealed film bags.

[0014] Preferably, the root cutting process is as follows:

[0015] The translation mechanism drives the translation plate to move the circular blade along the vertical conveyor direction and towards the leafy vegetable, aligning the circular blade with the root-cutting position of the leafy vegetable identified by the camera. Simultaneously, the lifting mechanism drives the pressure block to descend, bringing it into contact with the leafy vegetable and applying pressure within a preset range. Then, the controller controls the drive motor to rotate the circular blade, and the translation mechanism drives the translation plate to move the circular blade a preset distance in the opposite direction of the conveyor direction. The rotating circular blade cuts the root of the leafy vegetable, and the cut root enters the U-shaped guide plate through the opening. Then, the drive motor stops rotating the circular blade, and the translation mechanism drives the translation plate to move the circular blade first along the vertical conveyor direction and away from the leafy vegetable, and then moves it back to its original position in the same direction as the conveyor direction. The cut root inside the U-shaped guide plate slides to the ground.

[0016] Preferably, the process of removing yellow leaves is as follows:

[0017] ① Camera 2 identifies the location of yellow leaves on the leafy greens. If no yellow leaves are detected, the controller first controls the electric gripper to clamp the leafy greens, then controls drive motor 2 to drive the electric gripper to rotate the leafy greens 90°. Next, the controller controls the electric gripper to release the leafy greens, and then controls drive motor 2 to rotate the electric gripper 90° again. If yellow leaves are detected, translation mechanism 3 drives lifting mechanism 2 to move the electric suction cup above the yellow leaves. Lifting mechanism 2 drives the electric suction cup to descend, making the electric suction cup adhere to the yellow leaves. The controller controls the electric suction cup to hold the yellow leaves, and lifting mechanism 2 drives the electric suction cup to raise the held yellow leaves to a preset height 1. Drive component 1 drives the rotating blade to... The blade rotates towards the fixed blade edge to cut off the yellow leaves that have been sucked in. Drive component one drives the rotating blade to its original position. Translation mechanism three drives lifting mechanism two to move the electric suction cup and the cut yellow leaves to their original position. The controller controls the electric suction cup to release the yellow leaves, which fall to the ground. The controller controls the electric gripper to clamp the leafy greens. The controller controls drive motor two to drive the electric gripper to rotate the leafy greens 90°. The controller controls the electric gripper to release the leafy greens and controls drive motor two to drive the electric gripper to rotate 90°. ② Repeat step ① until the leafy greens are rotated back to their original position. Translation mechanism two drives drive motor two to move the electric gripper back to its original position, completing the removal of yellow leaves.

[0018] Preferably, the cleaning process is as follows:

[0019] The air bubbles generated by the exhaust holes of each exhaust pipe rise to the surface of the leafy greens and the gaps between the leaves and burst, generating local micro-jet streams and shock waves at the moment of bursting. These shock waves impact the dirt on the surface of the leafy greens and the gaps between the leaves. At the same time, water in the water tank is pumped to each nozzle by a water pump and sprayed out through each nozzle to form jets. The rising air bubbles drive the water flow to form turbulence, which, together with the jets sprayed from each nozzle, cleans the leafy greens. In addition, the jets sprayed from each nozzle generate directional thrust, pushing the leafy greens away from the conveyor mechanism in the cleaning tank. When the ultrasonic sensor detects that the leafy greens have moved to the front of the first baffle, the lifting mechanism drives the first baffle to descend to a preset height of two. The controller controls the drive motor to drive the L-shaped scooping plate to rotate upward by a preset angle of one, scooping out the leafy greens. The leafy greens fall onto the guide plate under their own gravity and then onto the drain plate. Then, the controller controls the drive motor to drive the L-shaped scooping plate to rotate downward to its original position, and the lifting mechanism drives the first baffle to rise to its original position.

[0020] Preferably, the draining process is as follows:

[0021] When camera three detects that the leafy greens have fallen onto the drain plate, the controller controls drive motor four to drive the rotating shaft, which in turn drives each cam to rotate. Each cam causes the drain plate to vibrate up and down, shaking off the water from the leafy greens. As the drain plate vibrates up and down, the leafy greens move to the lower end of the drain plate. At the same time, camera three detects the moisture content of the leafy greens. When the moisture content of the leafy greens drops to a preset moisture content range, the controller controls drive motor four to stop driving the rotating shaft to rotate and controls drive motor five to drive baffle two to rotate downwards by a preset angle two. The leafy greens fall along baffle two onto conveyor mechanism two.

[0022] Preferably, the packaging process is as follows:

[0023] Conveyor mechanisms three and four begin to operate synchronously. Simultaneously, drive assembly two drives the two rollers of each roller group to rotate relative to each other, causing the film and the leafy greens pressed in the middle of the film to be conveyed forward. As the film is conveyed forward, it pulls the film roll to rotate, releasing part of the film. Two transverse heating aluminum blocks heat the film, melting the two sides together to create a transverse seal around the leafy greens. When camera four captures the leafy greens moving to a preset position on conveyor mechanism three, conveyor mechanisms three and four stop operating. Drive assembly two stops driving the roller groups, and the two transverse heating aluminum blocks stop heating. Lifting mechanism four drives the mounting plate to lower the straight blade and the corresponding two vertical sealing heating aluminum blocks to a preset height three, causing the straight blade to embed into the straight groove and cut the film. Simultaneously, the vertical sealing heating aluminum blocks heat the ends of the two severed film segments near the straight blade to create a heat-sealing effect. Then, the vertical sealing heating aluminum blocks stop. Heating and lifting mechanism four drive the mounting plate to raise the straight blade and the corresponding two vertical sealing heating aluminum blocks to their original positions; then belt conveyor three and belt conveyor four continue to work synchronously, each drive component two continues to drive the two rollers of each roller group to rotate relative to each other, and the two horizontal heating aluminum blocks continue to heat. When camera four captures the leafy vegetable moving to the preset position on belt conveyor four, belt conveyor three and belt conveyor four stop working, each drive component two stops driving each roller group, the two horizontal heating aluminum blocks stop heating, and lifting mechanism four drive the mounting plate to lower the straight blade and the corresponding two vertical sealing heating aluminum blocks to a preset height three. Each vertical sealing heating aluminum block heats up, the straight blade cuts the film, and each vertical sealing heating aluminum block heats up, and the ends of the two cut film segments near the straight blade are heat-sealed, realizing the sealing of both sides and the two ends of the film wrapping the leafy vegetable, forming a sealed film bag, thus completing the packaging of the leafy vegetable.

[0024] The present invention has the following beneficial effects:

[0025] This invention enables the processing of leafy vegetables, including root cutting, yellow leaf removal, washing, draining, weighing, and packaging. It is multifunctional, highly intelligent, and achieves high-quality processing of leafy vegetables. Specifically, the washing mechanism, draining mechanism, weighing mechanism, and packaging mechanism are all located at the output end of the root cutting and yellow leaf removal mechanism, respectively. The high degree of integration is achieved by sequentially performing root cutting, yellow leaf removal, washing, and draining on each leafy vegetable. After these processes, the vegetables are conveyed to the weighing mechanism. When the weighing device detects that the total weight of the vegetables exceeds a preset weight, the vegetables are transferred to a film in the packaging mechanism. The hot-melt horizontal sealing component in the packaging mechanism horizontally seals both sides of the film wrapping the vegetables, causing the film to heat-melt together. The hot-melt vertical sealing component heat-melts both ends of the film wrapping the vegetables, forming a sealed film bag, thus completing the packaging of the leafy vegetables. Specifically, the root cutting and yellow leaf removal... The system uses pressure sensors to adaptively apply pressure to different varieties and sizes of leafy vegetables. Visual recognition feedback controls the translation mechanism to drive a circular blade for precise root cutting, achieving differentiated adaptive root cutting for different varieties and sizes. Visual recognition feedback also controls the translation mechanism and lifting mechanism to drive an electric suction cup to precisely position and adsorb yellow leaves. Electric grippers rotate the leafy vegetables, and a scissor assembly cuts the yellow leaves, achieving precise removal of yellow leaves from multiple sides. The washing mechanism employs a flexible air-water synergistic turbulent scrubbing method to efficiently clean the leafy vegetables while avoiding damage during the process. A water level sensor detects water turbidity and changes the water promptly, while a water level sensor limits the water level to prevent overflow. An ultrasonic sensor detects the position of the leafy vegetables for accurate removal. The draining mechanism uses visual recognition to control water usage as needed to maintain freshness standards. Attached Figure Description

[0046] This invention provides a multifunctional processing method for leafy vegetables, as detailed below:

[0047] The inlet of the water inlet pipe is connected to the water storage tank via a water pump, and the outlet of the water outlet pipe is connected to the collection tank via a solenoid valve. When the solenoid valve is closed, the water pump operates, pumping water from the water storage tank into the cleaning tank 2-1 through the inlet pipe, each water supply pipe 2-4, and each nozzle 2-5, so that the cleaning tank 2-1 is filled with water to a preset depth. The air pump delivers air into the cleaning tank 2-1 through the main pipe 2-10 and each exhaust pipe 2-2, forming a large number of bubbles in the water in the cleaning tank 2-1. At the same time, the water in the water storage tank is pumped to each nozzle 2-5 by the water pump and sprayed out through each nozzle 2-5. Two support frames 5-12 are placed on the ground. The placement shaft 5-13 is taken out and the film roll is placed on the placement shaft 5-13. The limiting cylinders 5-14 are placed on the two ends of the film roll on the placement shaft 5-13. Then, the two ends of the placement shaft 5-13 are placed in the U-shaped grooves opened on the two support frames 5-12. The two ends of the film roll are limited by the two limiting cylinders 5-14. The film roll is pulled out and covered on the guide plate 2 5-2. Then, the two sides (sides) of the film are attached together and pass through the gap between the two rollers 5-4 of one roller group, the gap between the two horizontal sealing heating aluminum blocks 5-8 of the hot melt horizontal sealing assembly, and the gap between the two rollers 5-4 of another roller group in sequence, so that each roller group clamps the two sides of the film that are attached together.

[0048] At preset time intervals, a leafy vegetable (transported by a conveyor or placed manually) is placed between two adjacent partitions at the input end of the conveyor belt mechanism 1-2, with the root of the vegetable facing the circular blade 1-5. Camera 1-3 identifies the cutting position of the vegetable root. The conveyor belt mechanism 1-2 then operates, transporting the vegetable to below the pressure block 1-8. The conveyor belt mechanism 1-2 pauses operation to perform the root cutting process. The root cutting process is as follows: the translation mechanism 1-7 drives the translation plate 1-4, moving the circular blade 1-5 along a direction perpendicular to the conveying direction of the conveyor belt mechanism 1-2 and closer to the vegetable, aligning the circular blade 1-5 with the cutting position of the vegetable root identified by the camera. Simultaneously, the lifting mechanism 1-9 drives the pressure block 1-8 to descend, bringing it into contact with the vegetable. The pressure is then detected by a pressure sensor. Apply pressure within a preset pressure range to the leafy vegetable. Then, the controller controls the drive motor to drive the circular blade 1-5 to rotate. The translation mechanism 1-7 drives the translation plate 1-4 to move the circular blade 1-5 a preset distance in the opposite direction to the conveyor belt 1-2. The rotating circular blade 1-5 cuts the root of the leafy vegetable. The cut root enters the U-shaped guide plate 1-6 through the opening. Then, the drive motor stops driving the circular blade 1-5 to rotate. The translation mechanism 1-7 drives the translation plate 1-4 to move the circular blade 1-5 first along the direction perpendicular to the conveyor belt 1-2 and away from the leafy vegetable, and then moves it back to its original position in the same direction as the conveyor belt 1-2. The cut root inside the U-shaped guide plate 1-6 slides to the ground (or is placed in the corresponding trash can).

[0049] After the root cutting is completed, the conveyor mechanism 1-2 continues to operate, transporting the root-cut leafy vegetables to below the shear assembly 1-17. The translation mechanism 1-13 drives the drive motor 2 to move the electric gripper 1-11 along the direction perpendicular to the conveyor mechanism 1-2 and closer to the leafy vegetables, placing the root-cut leafy vegetables between the two gripping blocks of the electric gripper 1-11. Then, the yellow leaf removal process is performed. Simultaneously, new leafy vegetables placed on the conveyor mechanism 1-2 are transported to below the pressing block 1-8 for root cutting. The yellow leaf removal process... The process is as follows: ① Camera 2 1-10 identifies the location of the yellow leaves of the leafy vegetable. If no yellow leaves are detected, the controller first controls the electric gripper 1-11 to clamp the leafy vegetable, and then controls the drive motor 2 to drive the electric gripper 1-11 to rotate the leafy vegetable 90°. Then, the controller controls the electric gripper 1-11 to release the leafy vegetable, and then controls the drive motor 2 to drive the electric gripper 1-11 to rotate 90°. If a yellow leaf is detected, the translation mechanism 3 1-15 drives the lifting mechanism 2 1-16 to move the electric suction cup 1-14 to move above the yellow leaf. The lifting mechanism 2 1-16 then drives the electric suction cup 1-14 to move the suction cup 1-14 to move above the yellow leaf. Suction cup 1-14 descends, bringing the electric suction cup 1-14 into contact with the yellow leaf. The controller controls the electric suction cup 1-14 to hold the yellow leaf. Lifting mechanism 2 1-16 drives the electric suction cup 1-14 to lift the held yellow leaf to a preset height. Drive component 1 drives the rotating blade to rotate closer to the fixed blade, cutting off the held yellow leaf. Drive component 1 drives the rotating blade to return to its original position. Translation mechanism 3 1-15 drives lifting mechanism 2 1-16 to move the electric suction cup 1-14 and the cut yellow leaf back to their original positions. The controller controls the electric suction cup 1-14 to release the yellow leaves, which fall to the ground (or be placed in the corresponding trash can). The controller then controls the electric gripper 1-11 to clamp the leafy greens, and controls the drive motor 2 to drive the electric gripper 1-11 to rotate the leafy greens 90°. The controller then controls the electric gripper 1-11 to release the leafy greens, and controls the drive motor 2 to drive the electric gripper 1-11 to rotate 90°. ② Repeat step ① until the leafy greens are rotated back to their original position. The translation mechanism 2 1-13 drives the drive motor 2 to move the electric gripper 1-11 back to its original position, completing the removal of the yellow leaves.

[0050] As the conveyor belt 1-2 intermittently transports the leafy vegetables, each vegetable undergoes root cutting and yellow leaf removal before being sent to the washing tank 2-1 for washing. After washing, they are sent to the drain plate 3-2 for draining, and then to the conveyor belt 4-4. The washing process involves air bubbles generated by the vents of each vent pipe 2-2 rising to the surface of the leafy vegetables and the gaps between the leaves, bursting and generating localized micro-jet streams and shock waves that impact the dirt on the surface and between the leaves. Simultaneously, water from the storage tank is pumped to each nozzle 2-5, forming jets. The rising air bubbles create intense turbulence, which, combined with the jets from each nozzle 2-5, simulates manual washing, effectively cleaning the leafy vegetables. The flexible cleaning method of coordinated turbulent scrubbing not only cleans leafy vegetables but also avoids damage during the cleaning process. In addition, the jets sprayed from each nozzle 2-5 form a directional thrust, pushing the leafy vegetables towards the cleaning box 2-1 away from the conveyor mechanism 1-2. When the ultrasonic sensor detects that the leafy vegetables have moved to the front of the baffle 2-6 (the side of the baffle 2-6 away from the conveyor mechanism 1-2), the lifting mechanism 3 2-7 drives the baffle 2-6 to descend to a preset height 2. The controller controls the drive motor 3 to drive the L-shaped scooping plate 2-8 to rotate upward by a preset angle 1, scooping out the leafy vegetables. Under their own gravity, the leafy vegetables fall onto the guide plate 2-9 and then onto the drain plate 3-2. Then, the controller controls the drive motor 3 to drive the L-shaped scooping plate 2-8 to rotate downward to its original position, and the lifting mechanism 3 2-7 drives the baffle 2-6 to rise to its original position. In addition, during the process of removing yellow leaves, camera 21-10 also identifies dirt on the leafy vegetables. The controller then determines the level of dirtiness based on the area and thickness of the dirt, and adjusts the bubble generation frequency and jet water flow size accordingly. There are three levels of dirtiness for the leafy vegetables. The higher the level of dirtiness, the higher the bubble generation frequency and jet water flow size need to be adjusted. The bubble generation frequency is adjusted by changing the air pump power, and the jet water flow size is adjusted by changing the water pump power.

[0051] The draining process is as follows: When camera 3-6 detects that the leafy vegetables have fallen onto the drain plate 3-2, the controller controls drive motor 4 to drive rotating shaft 3-3 to rotate each cam 3-4. Each cam 3-4 causes the drain plate 3-2 to vibrate up and down, shaking off the water from the leafy vegetables. As the drain plate 3-2 vibrates up and down, the leafy vegetables move to the lower end of the drain plate 3-2. At the same time, camera 3-6 detects the moisture content of the leafy vegetables. When the moisture content of the leafy vegetables drops to a preset moisture content range, the controller controls drive motor 4 to stop driving rotating shaft 3-3 to rotate, and controls drive motor 5 to drive baffle 2 3-5 to rotate downwards by a preset angle 2. The leafy vegetables fall along baffle 2 3-5 onto conveyor mechanism 2 4-4.

[0052] When the weighing device 4-2 detects that the total weight of the leafy vegetables on the conveyor belt 4-4 exceeds the preset weight, the conveyor belt 4-4 operates for a preset time to transport these leafy vegetables into the film on the guide plate 5-2. Some of the leafy vegetables are located within the film adhered to both sides of the conveyor belt 5-3. Then, the packaging process begins, placing these leafy vegetables into sealed film bags. The packaging process is as follows: the conveyor belt 5-3 and the conveyor belt 5-7 begin operating synchronously. Simultaneously, each drive component 2 drives the two rollers 5-4 of each roller group to rotate relative to each other, causing the film and the leafy vegetables pressed against the film to be conveyed forward. As the film moves forward... The conveyor pulls the film roll to rotate, releasing part of the film. Two transverse heating aluminum blocks heat the film, fusing the two sides together to achieve a transverse seal around the leafy vegetables. When camera 4 (5-5) captures the leafy vegetables moving to a preset position on conveyor mechanism 3 (5-3), both conveyor mechanisms 3 (5-3) and 4 (5-7) stop operating. Drive components 2 stop driving the roller groups, and the two transverse heating aluminum blocks stop heating. Lifting mechanism 4 (5-6) drives the mounting plate, lowering the straight blade 5-10 and the corresponding two vertical sealing heating aluminum blocks 5-9 to a preset height 3, causing the straight blade 5-10 to embed into the straight groove and cut the film. Simultaneously, each vertical sealing heating aluminum block 5-9 heats up, performing heat-sealing on the ends of the two disconnected film segments near the straight blade 5-10. Then, each vertical sealing heating aluminum block 5-9 stops heating, and the lifting mechanism four 5-6 drives the mounting plate to raise the straight blade 5-10 and the corresponding two vertical sealing heating aluminum blocks 5-9 to their original positions. Then, the belt conveyor three 5-3 and belt conveyor four 5-7 continue to work synchronously, and each drive component two continues to drive the two rollers 5-4 of each roller group to rotate relative to each other. The two horizontal heating aluminum blocks continue to heat up. When the camera four 5-5 captures the leafy vegetable moving to the preset position on the belt conveyor four 5-7, the belt conveyor... When structure 3 (5-3) and conveyor mechanism 4 (5-7) stop working, each drive component 2 stops driving each roller group, and the two horizontal heating aluminum blocks stop heating, the lifting mechanism 4 (5-6) drives the mounting plate to lower the straight blade 5-10 and the corresponding two vertical sealing heating aluminum blocks 5-9 to a preset height 3. Each vertical sealing heating aluminum block 5-9 heats up, the straight blade 5-10 cuts the film, and each vertical sealing heating aluminum block 5-9 heats up. The ends of the two cut film segments near the straight blade 5-10 are then heat-sealed, thereby achieving sealing on both sides and at both ends of the film wrapping these leafy vegetables, forming a sealed film bag, thus realizing the packaging of these leafy vegetables.

[0053] Furthermore, when the water level detector detects that the turbidity of the water in cleaning tank 2-1 exceeds the preset value, all operations are suspended. The controller opens the solenoid valve, and the water in cleaning tank 2-1 flows into the collection tank through the outlet pipe until the water level sensor detects that the water level in cleaning tank 2-1 is lower than the preset water level value one. At this point, the turbid water in cleaning tank 2-1 is discharged, the controller closes the solenoid valve, and the water pump starts to pump water from the storage tank through the inlet pipe, each water delivery pipe 2-4, and each nozzle 2-5 into cleaning tank 2-1, so that cleaning tank 2-1 is filled with water at the preset depth. Then all operations continue. When the water level sensor detects that the water level in cleaning tank 2-1 exceeds the preset water level value two, the controller opens the solenoid valve, and the water in cleaning tank 2-1 flows into the collection tank through the outlet pipe until the water level in cleaning tank 2-1 drops to the preset depth. At this point, the controller closes the solenoid valve.

Next, the controller controls the electric gripper to release the leafy greens, and then controls drive motor 2 to rotate the electric gripper 90° again. If yellow leaves are detected, translation mechanism 3 drives lifting mechanism 2 to move the electric suction cup above the yellow leaves.

These shock waves impact the dirt on the surface of the leafy greens and the gaps between the leaves. At the same time, water in the water tank is pumped to each nozzle by a water pump and sprayed out through each nozzle to form jets. The rising air bubbles drive the water flow to form turbulence, which, together with the jets sprayed from each nozzle, cleans the leafy greens. In addition, the jets sprayed from each nozzle generate directional thrust, pushing the leafy greens away from the conveyor mechanism in the cleaning tank. When the ultrasonic sensor detects that the leafy greens have moved to the front of the first baffle, the lifting mechanism drives the first baffle to descend to a preset height of two.

When the moisture content of the leafy greens drops to a preset moisture content range, the controller controls drive motor four to stop driving the rotating shaft to rotate and controls drive motor five to drive baffle two to rotate downwards by a preset angle two. The leafy greens fall along baffle two onto conveyor mechanism two.

Two transverse heating aluminum blocks heat the film, melting the two sides together to create a transverse seal around the leafy greens. When camera four captures the leafy greens moving to a preset position on conveyor mechanism three, conveyor mechanisms three and four stop operating. Drive assembly two stops driving the roller groups, and the two transverse heating aluminum blocks stop heating. Lifting mechanism four drives the mounting plate to lower the straight blade and the corresponding two vertical sealing heating aluminum blocks to a preset height three, causing the straight blade to embed into the straight groove and cut the film. Simultaneously, the vertical sealing heating aluminum blocks heat the ends of the two severed film segments near the straight blade to create a heat-sealing effect. Then, the vertical sealing heating aluminum blocks stop. Heating and lifting mechanism four drive the mounting plate to raise the straight blade and the corresponding two vertical sealing heating aluminum blocks to their original positions; then belt conveyor three and belt conveyor four continue to work synchronously, each drive component two continues to drive the two rollers of each roller group to rotate relative to each other, and the two horizontal heating aluminum blocks continue to heat.
