Before the tipping bucket 64 flips over, one side thereof is attached to the end face of the paper lunch box inlet conveyor belt 5, and the paper lunch box located in the positioning groove 9 is pushed over by the pushing cylinder and directly placed on the tipping bucket 64, and then the tipping bucket 64 is driven to flip by the flipping cylinder 65. After flipping, it can be pushed to the paper lunch box inlet conveyor belt 5 by the pushing box rod 100 and further pushed to the paper lunch box inlet mechanism 7 at the carton opening entrance of the carton discharge position 2 for operation.

[0025] The paper lunch box inlet mechanism 7 includes a positioning guide plate 71, a baffle plate 72 that moves up and down, a third push plate 73 that moves forward and backward, and a plug plate 74 that is telescopic along the end surface of the paper lunch box inlet conveyor belt 5. The plug plate 74 is driven by an insertion cylinder 75. The third push plate 73 is installed on a sliding seat of a third linear motion module 50. The baffle plate 72 is driven by a positioning cylinder to move up and down. The positioning guide plate 71 is mounted on one side of the paper lunch box inlet conveyor belt 5. A limit plate 76 is provided on one side of the paper lunch box inlet conveyor belt 5 close to the carton discharge position 2. The limit plate 76 is connected to the positioning guide plate 71. A limiting groove is formed between the plates 71, and a guiding bend at one end of the positioning guide plate 71 is used to guide the paper lunch box into the limiting groove. When the paper lunch box is delivered to the entrance of the carton by the paper lunch box feeding conveyor belt 5, it is placed on the extended plug plate 74, and the front end of the plug plate 74 is connected to the entrance of the carton. The baffle 72 is moved down by the positioning cylinder to position the paper lunch box, and then the paper lunch box placed horizontally at the entrance of the carton is pushed into the carton by the third push plate 73. The subsequent paper lunch boxes are transported in this way in turn, and the cartons are appropriately moved down layer by layer at the carton discharge position 2 according to the number of layers to be arranged of the paper lunch boxes.

[0026] The structure of the carton discharge position 2 includes an upper and lower movable slot 21 for carton surrounded by a fence, and a pallet 22 that can be lifted up and down is arranged at the bottom of the upper and lower movable slot 21 for carton, and the pallet 22 slides along a vertical guide rail, and also includes a belt arranged around it, which is driven by a servo motor, and the pallet 22 is connected to the belt, so that the servo motor can control the lifting and lowering of the pallet 22, and the carton is placed on the pallet 22 to match the paper lunch box entry position that needs to be boxed, and when the paper lunch box is pushed into the carton to stack the first layer, the servo motor can drive the pallet 22 to move down, so that the second layer of the paper lunch box is aligned with the end face of the paper lunch box entry conveyor belt 5 for conveying in the original way of paper lunch box installation, and after the second layer of paper lunch boxes are stacked in the carton, if necessary, the carton can be moved down to stack the third layer of paper lunch boxes, and the pallet 22 can also be arranged to be flippable, and after the pallet is flipped, the filled cartons are sent to the rollers arranged in sequence for output.

[0027] Among them, the structural principles of the first linear motion module 30, the second linear motion module 40, and the third linear motion module 50 are roughly the same, mainly including a guide rail, a sliding seat sliding on the guide rail, and a surrounding belt. The belt is controlled by a servo motor, and the sliding seat is connected to the belt, so that the servo motor can control the sliding seat to reciprocate linearly along the guide rail.

[0028] Finally, the paper lunch box packing machine is provided with a PLC control system and a plurality of photoelectric position sensors. The PLC control system controls various motors, solenoid valves and other controlled components, and then controls the accurate operation of the first, second and third linear motion modules. At the same time, the speed of the paper lunch box conveyor belt 4 and the paper lunch box inlet conveyor belt 5 can also be controlled, so that each mechanism can complete precise movements.

[0029] The working principle of the paper lunch box packing machine is as follows: after the paper lunch box is output to the positioning groove 9 through the paper lunch box conveyor belt 4, its direction is to be horizontally placed along the carton opening, and the piston rod of the pushing cylinder can push the paper lunch box in the positioning groove 9 out of the positioning groove 9 and push it onto the paper lunch box inlet conveyor belt 5 and locate it at the paper lunch box flipping mechanism 6. If flipping is required, it can be flipped through the flipping bucket 64 of the paper lunch box flipping mechanism 6. After flipping, it is pushed into the paper lunch box inlet conveyor belt 5 by the pushing box rod 100 and is limited by the limiting groove and transported to the paper At the entrance position of the box opening, the paper lunch box is pushed into the carton through the paper lunch box feeding mechanism 7 at the entrance position of the carton opening. After the conveyed paper lunch boxes are stacked in the carton for one layer, the carton drops to the height of one paper lunch box at the carton discharge position 2 and continues to stack the second layer. When stacking above the second layer, the insert plate extends out and is inserted into the carton, making the pushing of the paper lunch box smoother and more reliable, thereby filling the carton. Of course, the specifications of the inner cavity of the carton and the specifications of the paper lunch box need to be accurately calculated and matched, so that there will be no large gaps in the paper lunch boxes after packing.

[0030] By adopting the above technical scheme, the paper lunch box can be placed in the paper lunch box feeding trough 8, pushed to the paper lunch box conveyor belt 4 by the first push plate 10, and then pushed into the positioning groove 9 by the second push plate 20. The pushing cylinder pushes the paper lunch box in the positioning groove 9 into the input end of the paper lunch box box-entering conveyor belt 5 and reaches the position of the paper lunch box flipping mechanism 6. At this time, whether the paper lunch box flipping mechanism 6 is enabled depends on the specifications of the paper lunch box and the carton. When the paper lunch box flipping mechanism 6 needs to be enabled, the paper lunch box is flipped 90 degrees, and then the paper lunch box is positioned at the opening of the carton through the paper lunch box box-entering mechanism 7 and the horizontally placed paper lunch boxes are pushed into the carton one by one. In this way, the purpose of flipping the paper lunch box to adjust the position of the paper lunch box to adapt to the specifications of the carton is achieved, thereby greatly improving the adaptability of packing and work efficiency.
