[0049] In the automatic meal distribution section, the XZ-axis rotary clamping structure 8 at the lunch box loading station 5 on the lunch box 24 picks up the lunch box 24 from the lunch box 24 warehouse 3 regularly and intermittently at a predetermined time interval and transfers it to the conveyor line 1. The lunch box 24 is conveyed by the conveyor line 1 and passes through the discharge hoppers of different dish storage and discharging devices 2 at certain intervals. An automatic positioning device is arranged beside the conveyor belt at the discharge hopper. The automatic positioning device is equipped with a position sensor. When it detects the lunch box 24, it controls the operation of the automatic positioning device. By extending the output end of the cylinder, the L-shaped baffle 12 is extended, so that the lunch box 24 touches the L-shaped baffle 12 and then stops below the discharge hopper, that is, the lunch box 24 enters the "C"-shaped structure through the notch on the "C"-shaped structure and is located below the discharge hopper; an object monitoring sensor is arranged at the discharge port of the dish storage and discharging device 2. When it detects that the lunch box 24 reaches below the discharge port, according to the requirements of the order, the discharge hopper starts to open to select for discharging and meal distribution; after discharging, after a set fixed time, the automatic positioning device retracts the L-shaped baffle 12. The stopped conveyor belt starts to run. After multiple operations, the lunch box 24 is meal-distributed in sequence; due to the existence of the automatic positioning device, the lunch box 24 can be reasonably located below the discharge hopper, thus ensuring that each dish is put in the appropriate position. After meal distribution is completed, the XZ-axis rotary clamping structure 8 on the lunch box cover loading station picks up the lunch box cover from the lunch box cover warehouse 4 and transfers it to the conveyor line 2. Through the same operation of another automatic positioning device, the position sensor detects the lunch box 24, manipulates the L-shaped baffle to extend, and the XZ-axis rotary clamping structure 8 can correctly place the lunch box cover on the lunch box 24. Then, through the positioning of the automatic positioning device in the same way, the lunch box cover is pressed by the elongation of the first cylinder at the capping station to drive the pressing plate to press. During passing through each operation, the automatic positioning device effectively ensures that the lunch box 24 stops, enabling the operation to be carried out successfully. The meal distribution process is completed, and the ordered dishes are meal-distributed and boxed. Then the lunch box 24 is lifted by the clamping device and lowered to the automatic packaging section.

[0050] In the automatic packaging part, the packaging bag 61 is placed in the bag feeding bin 62 of the bag feeding device 6. One side of the packaging bag 61 is pressed by the spring push plate 16, and the other side is rolled by the roller 65 to extract the packaging bag 61 from the bag feeding bin 62. At this time, the second vacuum suction cup of the bag holding device clamps the extracted packaging bag 62, and the bag holding bin 64 slides to the conveyor line 1 by sliding on the fourth bracket. First, the bag holding device is activated to open the packaging bag 61, and then the clamping device clamps the lunch box 24 with the lunch box cover from the conveyor line 1 and puts it into the packaging bag. The automatic sealing device is translated to the opening of the packaging bag 61 and descends to press and heat-seal the opened packaging bag 61. The sealing treatment with moderate spacing and small heat-sealing area is adopted, which is easy to tear and will not cause damage. After the heat sealing action is completed, the bag holding device is triggered to release the second vacuum suction cup, and the packaging bag 61 falls and slides down to the platform 63, which can be taken by people, so that the takeaway meal preparation and packaging are completed.

[0051] The entire process can complete the automated meal preparation and packaging process for takeout without human intervention. Through the above design, the production line can realize the automated meal preparation and packaging process for takeout, greatly improving efficiency and reducing the errors and impacts that may be caused by human factors. At the same time, due to the high degree of automation, the accuracy and consistency of the sealing process can be ensured, thereby ensuring the quality and safety of food.

[0052] This production line mainly realizes the processes of loading lunch boxes 24, putting food into lunch boxes 24, putting lunch box lids on lunch boxes 24, pressing lunch box lids, putting packaging bags, opening packaging bags, clamping lunch boxes 24 with lunch box lids into packaging bags, and heat-sealing packaging bags, so as to realize the automatic meal preparation and packaging of food. The whole process does not require human intervention. At the same time, it reduces operating costs. Automated operation can save labor costs, improve operational efficiency, and avoid errors and waste. By realizing the automated packaging process, efficiency and quality are greatly improved, that is, the tightness of the sealing is improved, and the errors and impacts that may be caused by human factors are reduced. At the same time, various special needs can be met, such as beautiful packaging, and ultimately the quality and safety of food must be ensured. The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model.
