[0001] The present invention belongs to the technical field of food packing machines, and particularly relates to a dish packing machine. Background Art

[0002] A rice packing machine is a device used for packing rice, which is widely used in the catering field.

[0003] The invention patent with the application number CN202311103002.9 discloses a rice packing machine, including a frame. A rice loading tank and a number of weighing modules are installed on the frame. A bracket is connected to the weighing module, and a rice distributing tank is connected to the bracket. A number of rice distributing tanks are located below the rice loading tank. Two opening and closing hoppers are rotatably connected to the lower end of the rice distributing tank, and an opening and closing mechanism is connected between the two opening and closing hoppers; A transverse movement mechanism is also installed on the frame, and a clamping mechanism for clamping rice bags is installed on the transverse movement mechanism. A sealing mechanism for sealing rice bags is installed on the frame. The sealing mechanism is on one side corresponding to the transverse movement mechanism, and a bag discharging mechanism is arranged at the lower part of the frame. The present invention provides a rice packing machine that can accurately quantitatively fill and automatically seal rice bags.

[0004] However, the above-mentioned rice packing machine requires manual placement of rice bags and cannot achieve fully automated rice packing. Moreover, the above-mentioned rice packing machine can only be used for packing rice and cannot be used for packing dishes. Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a dish packing machine that does not require manual operation.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A dish packing machine includes a frame. An input material bin, a dish weighing unit, a dish temporary storage unit, a dish bag sealing unit, a dish bag fixed suction mechanism, and a dish bag conveyor belt are sequentially installed on the frame from top to bottom. A dish bag clamping unit, a dish bag flipping suction mechanism, and a dish bag storage bin are also installed on the frame. When the dish bag flipping suction mechanism flips to the horizontal position, it is directly below the dish bag storage bin. When the dish bag flipping suction mechanism flips to the vertical position, it is directly opposite to the dish bag fixed suction mechanism. The dish bag clamping unit is located between the dish bag fixed suction mechanism and the dish bag flipping suction mechanism.

[0008] Pour the prepared dishes into the feeding bin, and the feeding bin conveys the dishes to the dish weighing unit at a uniform speed for weighing by the dish weighing unit. After the dishes in the dish weighing unit reach the set value, pour the dishes into the dish temporary storage unit. At this time, the bag flipping and sucking mechanism sucks and holds one bag at the bottom of the bag storage bin, and the bag flipping and sucking mechanism flips to a position directly opposite the bag fixing and sucking mechanism. The bag clamping unit clamps both ends of the bag, and the bag fixing and sucking mechanism sucks the other side of the bag opening, so that the bag is opened. At this time, the dish temporary storage unit opens, and the dishes fall into the bag. After all the dishes in the dish temporary storage unit fall into the bag, the bag sealing unit clamps and heats the opening of the bag to complete bag sealing. After sealing, the bag falls onto the bag conveyor belt, and the packed dishes are automatically output.

[0009] The feeding bin of the present invention conveys the dishes, the dish weighing unit conducts accurate weighing, and the dish temporary storage unit temporarily stores the dishes to prepare for dish packing. The bag flipping and sucking mechanism can automatically suck and transfer the bag to a determined position, and when the bag clamping unit clamps both ends of the bag, the bag flipping and sucking mechanism and the bag fixing and sucking mechanism open the bag opening. The dishes in the dish temporary storage unit fall into the bag, and after packing, the bag sealing unit automatically seals the bag. The whole process of conveying, weighing, temporary storage, bag taking, bag clamping, bag opening, packing, bag sealing and output of the present invention is automated without manual operation. The bag flipping and sucking mechanism of the present invention can automatically take out the bag in the bag storage bin and flip the bag to a determined position, avoiding the operation of manual bag placement.

[0010] As a preferred embodiment of the present invention, the feeding bin includes a feeding hopper fixed to the top of the frame. An inclined feeding trough is provided at the bottom of the feeding hopper. A feeding driving mechanism is installed at one end of the feeding trough. The output end of the feeding driving mechanism is connected to a feeding screw. The feeding screw is arranged obliquely along the feeding trough. The higher end of the feeding trough is provided with a discharge port, and the discharge port is located above the dish weighing unit.

[0011] The feeding trough is inclined. When the feeding driving mechanism drives the feeding screw to rotate, the dishes are conveyed from the lower end of the feeding trough to the higher end, and then conveyed into the dish weighing unit. When the dishes are conveyed from low to high, the soup will not flow into the dish weighing unit, thus avoiding the situation that the dishes in the dish weighing unit contain more soup.

[0012] As a preferred embodiment of the present invention, a soup tank is provided at the bottom of the feeding trough. A number of soup filtering holes communicating with the soup tank are provided at the bottom of the feeding trough. A liquid pump is installed on the soup tank, and the outlet of the liquid pump is located above the dish weighing unit. The soup flows from the filtering holes into the soup tank, and the liquid pump separately conveys the soup into the dish weighing unit. When the feeding driving mechanism and the liquid pump work synchronously, it can ensure that the solid dishes and the soup are always conveyed into the dish weighing unit according to the set ratio, ensuring the stable ratio of the dishes with soup in each food bag.

[0013] As a preferred embodiment of the present invention, the dish weighing table unit includes a dish weighing device installed on the frame. A support frame is installed on the dish weighing device. One end of the support frame close to the dish temporary storage unit is rotatably connected with a turning and weighing hopper. A turning connecting rod is fixed on the rotating shaft of the turning and weighing hopper. A turning air cylinder is connected between the other end of the turning connecting rod and the other end of the support frame. When the dish weight reaches the set value, the turning air cylinder pushes the turning connecting rod to rotate, and the turning connecting rod drives the turning and weighing hopper to tilt at a certain angle, and the materials in the turning and weighing hopper are poured into the dish temporary storage unit. The dish weighing unit can automatically weigh and transfer the dishes.

[0014] As a preferred embodiment of the present invention, the dish temporary storage unit includes a blanking lifting air cylinder installed on the frame. A blanking hopper is connected to the piston rod of the blanking lifting air cylinder. The upper part of the blanking hopper is a blanking open section, and the lower part of the blanking hopper is a blanking closing section; the dish temporary storage unit further includes a horizontally arranged baffle air cylinder installed on the frame. The piston rod of the baffle air cylinder is connected with a sealing baffle for sealing the lower opening of the blanking closing section.

[0015] Before the dish weighing unit pours the dishes into the blanking hopper, the baffle air cylinder pushes out the sealing baffle, and the sealing baffle blocks the opening of the blanking closing section. When the food bag turning suction mechanism and the food bag fixing suction mechanism pull open the opening of the food bag, the baffle air cylinder drives the sealing baffle to retract, and the dishes fall into the food bag. When the dish weighing unit pours the dishes into the blanking hopper, the blanking open section can prevent the dishes from spilling. When opening the opening of the blanking closing section to add the dishes into the food bag, the blanking closing section can gather the dishes to prevent the dishes from spilling.

[0016] As a preferred embodiment of the present invention, the food bag sealing unit includes a food bag forward sealing air cylinder and a food bag reverse sealing air cylinder arranged in opposite directions and installed on the frame. The piston rod of the food bag forward sealing air cylinder is connected with a food bag forward sealing heating block.

The other end of the food bag reverse guide rod is connected with a food bag reverse sealing heating block. The food bag forward sealing air cylinder and the food bag reverse sealing air cylinder are both located on the side of the food bag forward sealing heating block away from the food bag reverse sealing heating block.

[0017] The forward vegetable bag sealing cylinder and the reverse vegetable bag sealing cylinder act simultaneously. The forward vegetable bag sealing cylinder drives the forward vegetable bag sealing heating block to extend, the reverse vegetable bag sealing cylinder pushes the reverse vegetable bag guide rod to extend, and the reverse vegetable bag guide rod pushes the reverse vegetable bag sealing heating block to extend. The forward vegetable bag sealing heating block and the reverse vegetable bag sealing heating block clamp and heat the opening of the vegetable bag from opposite directions to achieve automatic sealing of the vegetable bag.

[0018] Both the forward vegetable bag sealing cylinder and the reverse vegetable bag sealing cylinder are located on the side of the forward vegetable bag sealing heating block away from the reverse vegetable bag sealing heating block, so that the space between the forward vegetable bag sealing heating block and the reverse vegetable bag sealing heating block is not blocked, ensuring that the dishes can smoothly fall into the vegetable bag through this space.

[0019] A forward vegetable bag sealing guide plate is fixed on the piston rod of the forward vegetable bag sealing cylinder. The reverse vegetable bag guide rod passes through the forward vegetable bag sealing guide plate, and the forward vegetable bag sealing heating block is installed on the forward vegetable bag sealing guide plate. A reverse vegetable bag sealing guide plate is fixed on the piston rod of the reverse vegetable bag sealing cylinder. A vegetable bag sealing guide rod is fixed on the frame. The vegetable bag sealing guide rod passes through the reverse vegetable bag sealing guide plate, and the reverse vegetable bag guide rod is fixed on the reverse vegetable bag sealing guide plate. A vegetable bag sealing guide sleeve is also fixed on the frame. The reverse vegetable bag guide rod passes through the vegetable bag sealing guide sleeve. The forward vegetable bag sealing heating block and the reverse vegetable bag sealing heating block can be reliably guided during the moving process, ensuring reliable sealing of the vegetable bag.

[0020] As a preferred solution of the present invention, the vegetable bag clamping unit includes a vegetable bag clamping lifting cylinder installed on the frame. A vegetable bag clamping support is connected to the piston rod of the vegetable bag clamping lifting cylinder. Vegetable bag clamping adjustment cylinders are installed at both ends of the vegetable bag clamping support, and a vegetable bag clamping jaw cylinder is installed on the piston rod of the vegetable bag clamping adjustment cylinder. The rice bag clamping lifting cylinder drives the rice bag clamping support to move to a determined height position. According to the size of the rice bag, the vegetable bag clamping adjustment cylinder moves the vegetable bag clamping jaw cylinder to a determined position so that the distance between the two vegetable bag clamping jaw cylinders adapts to the size of the vegetable bag. The vegetable bag clamping jaw cylinder clamps both ends of the vegetable bag, facilitating the opening sides of the vegetable bag to be pulled apart by the vegetable bag flipping suction mechanism and the vegetable bag fixing suction mechanism.

[0021] As a preferred solution of the present invention, the vegetable bag fixing suction mechanism includes a vegetable bag fixing suction telescopic cylinder installed on the frame. A vegetable bag fixing suction frame is connected to the piston rod of the vegetable bag fixing suction telescopic cylinder. A number of vegetable bag fixing suction cups for sucking one side of the vegetable bag are installed on the vegetable bag fixing suction frame. The vegetable bag fixing suction cups are located on the side of the vegetable bag clamping jaw cylinder away from the vegetable bag flipping suction frame. The vegetable bag fixing suction telescopic cylinder pushes out the vegetable bag fixing suction frame, and a number of vegetable bag fixing suction cups on the vegetable bag fixing suction frame reliably suck one side of the vegetable bag.

[0022] As a preferred embodiment of the present invention, the vegetable bag flipping and sucking mechanism includes a vegetable bag flipping cylinder installed on the frame. A vegetable bag flipping frame is rotatably connected to the frame. A vegetable bag flipping connecting rod is fixed on the vegetable bag flipping frame. The piston rod of the vegetable bag flipping cylinder is rotatably connected to the other end of the vegetable bag flipping connecting rod. A first-stage vegetable bag extending cylinder is installed on the vegetable bag flipping frame. The piston rod of the first-stage vegetable bag extending cylinder is connected to a second-stage vegetable bag extending cylinder. The piston rod of the second-stage vegetable bag extending cylinder is connected to a vegetable bag flipping and sucking frame. A number of vegetable bag flipping suction cups for sucking the other side of the vegetable bag are installed on the vegetable bag flipping and sucking frame. When the vegetable bag flipping and sucking frame is flipped to the horizontal position, it is directly below the vegetable bag storage bin. When the vegetable bag flipping and sucking frame is flipped to the vertical position, it is directly opposite the vegetable bag fixing and sucking mechanism.

[0023] The piston rods of the first-stage vegetable bag extending cylinder and the second-stage vegetable bag extending cylinder extend in sequence, so that a number of vegetable bag flipping suction cups on the vegetable bag flipping and sucking frame can suck the lowermost vegetable bag in the vegetable bag storage bin. The vegetable bag flipping cylinder drives the vegetable bag flipping frame to flip by 90°, so that the vegetable bag can be flipped to the position directly opposite the vegetable bag fixing and sucking mechanism. At this time, the vegetable bag clamping unit clamps both ends of the vegetable bag, and the vegetable bag fixing and sucking mechanism sucks the other side of the vegetable bag, so that the opening of the vegetable bag can be opened. The vegetable bag flipping and sucking mechanism of the present invention can automatically suck the vegetable bag and flip the vegetable bag to the packing position without manual operation.

[0024] As a preferred embodiment of the present invention, the vegetable bag storage bin includes a vegetable bag dropping opening provided on the frame. Vegetable bag baffles are provided around the vegetable bag dropping opening. A supporting bottom edge for supporting the vegetable bag is left between the vegetable bag baffle and the edge of the vegetable bag dropping opening. The supporting bottom edge supports a number of stacked vegetable bags, so that when the lowermost vegetable bag is sucked out, the rest of the vegetables will not be pulled out. A number of stacked vegetable bags are placed in the vegetable bag storage bin. A number of vegetable bag flipping suction cups on the vegetable bag flipping and sucking frame suck and pull out the lowermost vegetable bag, and the rest of the vegetable bags are supported by the supporting bottom plate.

[0025] The beneficial effects of the present invention are as follows:

[0026] The feeding bin of the present invention conveys the vegetables. The vegetable weighing unit weighs accurately. The vegetable temporary storage unit temporarily stores the vegetables to prepare for packing the vegetables. The vegetable bag flipping and sucking mechanism can automatically suck and transfer the vegetable bag to a determined position, and when the vegetable bag clamping unit clamps both ends of the vegetable bag, the vegetable bag opening is opened by the vegetable bag flipping and sucking mechanism and the vegetable bag fixing and sucking mechanism. The vegetables in the vegetable temporary storage unit fall into the vegetable bag and are automatically sealed by the vegetable bag sealing unit after packing. The whole process of conveying, weighing, temporarily storing, taking the bag, clamping the bag, opening the bag, packing, sealing and output of the present invention is automated without manual operation. The vegetable bag flipping and sucking mechanism of the present invention can automatically take out the vegetable bag in the vegetable bag storage bin and flip the vegetable bag to a determined position, avoiding the operation of manual bag placement.

Detailed implementation manners

[0045] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0047] As Figures 1 to 17As shown in the figure, the dish packing machine of this embodiment includes a frame 1. On the frame 1, a feeding bin 2, a dish weighing unit 3, a dish temporary storage unit 4, a dish bag sealing unit 5, a dish bag fixed suction mechanism 6, and a dish bag conveyor belt 11 are installed in sequence from top to bottom. A dish bag clamping unit 8, a dish bag flipping suction mechanism 7, and a dish bag storage bin 12 are also installed on the frame 1. When the dish bag flipping suction mechanism 7 flips to the horizontal position, it is directly below the dish bag storage bin 12. When the dish bag flipping suction mechanism 7 flips to the vertical position, it is directly opposite to the dish bag fixed suction mechanism 6. The dish bag clamping unit 8 is located between the dish bag fixed suction mechanism 6 and the dish bag flipping suction mechanism 7.

[0048] Pour the prepared dishes into the feeding bin 2. The feeding bin 2 evenly conveys the dishes into the dish weighing unit 3 for weighing by the dish weighing unit 3. After the dishes in the dish weighing unit 3 reach the set value, they are poured into the dish temporary storage unit 4. At this time, the dish bag flipping suction mechanism 7 sucks a dish bag at the bottom of the dish bag storage bin 12 and flips to a position directly opposite to the dish bag fixed suction mechanism 6. The dish bag clamping unit 8 clamps both ends of the dish bag, and the dish bag fixed suction mechanism 6 sucks the other side of the dish bag opening, so that the dish bag is opened. At this time, the dish temporary storage unit 4 opens, and the dishes fall into the dish bag. After all the dishes in the dish temporary storage unit 4 fall into the dish bag, the dish bag sealing unit 5 clamps and heats the opening of the dish bag to complete the bag sealing. After sealing, the dish bag falls onto the dish bag conveyor belt 11, and the packed dishes are automatically output.

[0049] The feeding bin 2 of the present invention conveys the dishes, the dish weighing unit 3 accurately weighs them, and the dish temporary storage unit 4 temporarily stores the dishes to prepare for dish packing. The dish bag flipping suction mechanism 7 can automatically suck and transfer the dish bag to a determined position. When the dish bag clamping unit 8 clamps both ends of the dish bag, the dish bag opening is opened by the dish bag flipping suction mechanism 7 and the dish bag fixed suction mechanism 6. The dishes in the dish temporary storage unit 4 fall into the dish bag, and after packing, the dish bag is automatically sealed by the dish bag sealing unit 5. The whole process of conveying, weighing, temporarily storing, taking the bag, clamping the bag, opening the bag, packing, sealing the bag, and outputting of the present invention is automated and does not require manual operation. The dish bag flipping suction mechanism 7 of the present invention can automatically take out the dish bag in the dish bag storage bin 12 and flip the dish bag to a determined position, avoiding the operation of manually placing the bag.

[0050] Specifically, the feeding bin 2 includes a feeding hopper 21 fixed to the top of the frame 1. An inclined feeding trough 22 is provided at the bottom of the feeding hopper 21. A feeding drive mechanism 23 is installed at one end of the feeding trough 22. The output end of the feeding drive mechanism 23 is connected to a feeding screw 24. The feeding screw 24 is arranged obliquely along the feeding trough 22. The higher end of the feeding trough 22 is provided with a discharge port 25, and the discharge port 25 is located above the dish weighing unit 3.

[0051] The feeding drive mechanism 23 is a motor and a reducer. The feeding chute 22 is inclined. When the motor drives the reducer to operate and the reducer drives the feeding screw 24 to rotate, the dishes are conveyed from the lower end of the feeding chute 22 to the higher end, and then conveyed into the dish weighing unit 3. When the dishes are conveyed from low to high, the soup will not flow into the dish weighing unit 3, thus avoiding the situation that the dishes in the dish weighing unit 3 contain too much soup.

[0052] Furthermore, a soup trough 26 is arranged at the bottom of the feeding chute 22. A plurality of soup filtering holes 27 communicating with the soup trough 26 are arranged at the bottom of the feeding chute 22. A liquid pump is installed on the soup trough 26, and the outlet of the liquid pump is located above the dish weighing unit 3. The soup flows from the soup filtering holes 27 into the soup trough 26, and the liquid pump conveys the soup to the dish weighing unit 3 separately. When the feeding drive mechanism 23 and the liquid pump work synchronously, it can ensure that the solid dishes and the soup are always conveyed into the dish weighing unit 3 according to the set ratio, ensuring the stable ratio of the soup contained in the dishes loaded in each food bag.

[0053] Specifically, the dish weighing table unit includes a dish weighing device 31 installed on the frame 1. A support frame 32 is installed on the dish weighing device 31. One end of the support frame 32 close to the dish temporary storage unit 4 is rotatably connected with a tipping weighing hopper 33. A tipping connecting rod 34 is fixed on the rotating shaft of the tipping weighing hopper 33. A tipping cylinder 35 is connected between the other end of the tipping connecting rod 34 and the other end of the support frame 32. When the weight of the dishes reaches the set value, the tipping cylinder 35 pushes the tipping connecting rod 34 to rotate, and the tipping connecting rod 34 drives the tipping weighing hopper 33 to tilt at a certain angle, and the materials in the tipping weighing hopper 33 are poured into the dish temporary storage unit 4. The dish weighing unit 3 can realize the automatic weighing and transfer of the dishes.

The piston rod of the baffle cylinder 43 is connected with a sealing baffle 44 for sealing the lower opening of the blanking closing section.

[0055] Before the dish weighing unit 3 pours the dishes into the blanking hopper 42, the baffle cylinder 43 pushes out the sealing baffle 44, and the sealing baffle 44 blocks the opening of the blanking closing section. When the food bag flipping suction mechanism 7 flips and the food bag fixing suction mechanism 6 pulls open the opening of the food bag, the baffle cylinder 43 drives the sealing baffle 44 to retract, and the dishes fall into the food bag. When the dish weighing unit 3 pours the dishes into the blanking hopper 42, the blanking open section can prevent the dishes from spilling. When the opening of the blanking closing section is opened to add the dishes into the food bag, the blanking closing section can gather the dishes to prevent the dishes from spilling.

[0056] Specifically, the vegetable bag sealing unit 5 includes a vegetable bag forward sealing cylinder 51 and a vegetable bag reverse sealing cylinder 52 which are arranged on the frame 1 in opposite directions. The piston rod of the vegetable bag forward sealing cylinder 51 is connected with a vegetable bag forward sealing heating block 53. The piston rod of the vegetable bag reverse sealing cylinder 52 is connected with a vegetable bag reverse guide rod 54. The other end of the vegetable bag reverse guide rod 54 is connected with a vegetable bag reverse sealing heating block 55. Both the vegetable bag forward sealing cylinder 51 and the vegetable bag reverse sealing cylinder 52 are located on the side of the vegetable bag forward sealing heating block 53 away from the vegetable bag reverse sealing heating block 55.

[0057] The vegetable bag forward sealing cylinder 51 and the vegetable bag reverse sealing cylinder 52 act simultaneously. The vegetable bag forward sealing cylinder 51 drives the vegetable bag forward sealing heating block 53 to extend. The vegetable bag reverse sealing cylinder 52 pushes the vegetable bag reverse guide rod 54 to extend. The vegetable bag reverse guide rod 54 pushes the vegetable bag reverse sealing heating block 55 to extend. The vegetable bag forward sealing heating block 53 and the vegetable bag reverse sealing heating block 55 clamp and heat the opening of the vegetable bag from opposite directions, realizing automatic sealing of the vegetable bag.

[0058] Both the vegetable bag forward sealing cylinder 51 and the vegetable bag reverse sealing cylinder 52 are located on the side of the vegetable bag forward sealing heating block 53 away from the vegetable bag reverse sealing heating block 55, so that the space between the vegetable bag forward sealing heating block 53 and the vegetable bag reverse sealing heating block 55 is not blocked, ensuring that the dishes can smoothly fall into the vegetable bag from this space.

[0059] A vegetable bag forward sealing guide plate 56 is fixed on the piston rod of the vegetable bag forward sealing cylinder 51. The vegetable bag reverse guide rod 54 passes through the vegetable bag forward sealing guide plate 56. The vegetable bag forward sealing heating block 53 is installed on the vegetable bag forward sealing guide plate 56. A vegetable bag reverse sealing guide plate 57 is fixed on the piston rod of the vegetable bag reverse sealing cylinder 52. A vegetable bag sealing guide rod 58 is fixed on the frame 1.

Vegetable bag clamping adjustment cylinders 83 are installed at both ends of the vegetable bag clamping support 82. A vegetable bag clamping jaw cylinder 84 is installed on the piston rod of the vegetable bag clamping adjustment cylinder 83. The rice bag clamping lifting cylinder drives the rice bag clamping support to move to a determined height position. According to the size of the rice bag, the vegetable bag clamping adjustment cylinder 83 moves the vegetable bag clamping jaw cylinder 84 to a determined position so that the distance between the two vegetable bag clamping jaw cylinders 84 adapts to the size of the vegetable bag. The vegetable bag clamping jaw cylinder 84 clamps both ends of the vegetable bag, facilitating the opening of both sides of the opening of the vegetable bag through the vegetable bag flipping suction mechanism 7 and the vegetable bag fixing suction mechanism 6.

[0061] The vegetable bag fixing suction mechanism 6 includes a vegetable bag fixing suction telescopic cylinder 61 installed on the frame 1.

A number of vegetable bag flipping suction cups 77 for sucking the other side of the vegetable bag are installed on the vegetable bag flipping suction frame 76. When the vegetable bag flipping suction frame 76 is flipped to the horizontal position, it is directly below the vegetable bag storage bin 12. When the vegetable bag flipping suction frame 76 is flipped to the vertical position, it is directly opposite the vegetable bag fixing suction mechanism 6.

[0063] The piston rods of the vegetable bag first-stage extending cylinder 74 and the vegetable bag second-stage extending cylinder 75 extend in sequence, so that a number of vegetable bag flipping suction cups 77 on the vegetable bag flipping suction frame 76 can suck the lowest-layer vegetable bag in the vegetable bag storage bin 12. The vegetable bag flipping cylinder 71 drives the vegetable bag flipping frame 72 to flip 90°, so that the vegetable bag can be flipped to a position directly opposite the vegetable bag fixing suction mechanism 6. At this time, the vegetable bag clamping unit 8 clamps both ends of the vegetable bag, and the vegetable bag fixing suction mechanism 6 sucks the other side of the vegetable bag, so that the opening of the vegetable bag can be opened. The vegetable bag flipping suction mechanism 7 of the present invention can automatically suck the vegetable bag and can flip the vegetable bag to the packing position without manual operation.

[0064] A vegetable bag turnover frame position detection sensor 78 is installed on the rack 1, and a vegetable bag turnover frame induction plate 79 is fixed on the vegetable bag turnover frame 72. When the vegetable bag turnover suction frame 76 rotates to be directly below the vegetable bag storage bin 12, the vegetable bag turnover frame induction plate 79 contacts the vegetable bag turnover frame position detection sensor 78, ensuring that the vegetable bag turnover suction frame 76 can reliably suck the vegetable bag.

[0065] The vegetable bag storage bin 12 includes a vegetable bag dropping port 121 provided on the rack 1. Vegetable bag baffles 122 are provided around the vegetable bag dropping port 121, and a supporting bottom edge 123 for supporting the vegetable bag is left between the vegetable bag baffles 122 and the edge of the vegetable bag dropping port 121. The supporting bottom edge 123 supports a number of stacked vegetable bags, so that when the lowermost vegetable bag is sucked out, the rest of the vegetables will not be pulled out. A number of stacked vegetable bags are placed in the vegetable bag storage bin 12, and a number of vegetable bag turnover suction cups 77 on the vegetable bag turnover suction frame 76 suck and pull out the lowermost vegetable bag, and the rest of the vegetable bags are supported by the supporting bottom plate.

[0066] The present invention is not limited to the above optional embodiments. Any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they all fall within the protection scope of the present invention.
