DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Next, in combination with the attached Figure 1-2 A further detailed description will be made of the specific implementation manners of the present utility model.

[0020] In this embodiment, through Figure 1-2 As shown, the present utility model includes an operating table 1, a fixed mold 3 is arranged at the middle position of the top of the operating table 1, support frames 4 are arranged at both ends of the top of the operating table 1, a support plate 5 is fixedly installed on the support frames 4, a first cylinder 6 is fixed at the middle position of the support plate 5, the output end of the first cylinder 6 is fixed with a movable mold 7, a discharging assembly is arranged inside the operating table 1, and a material receiving assembly cooperating with the discharging assembly is arranged on the operating table 1. After the first cylinder 6 drives the movable mold 7 to descend into the fixed mold 3 to complete stamping, the discharging assembly pushes out the stamped aluminum foil lunch boxes, and the material receiving assembly collects and stacks the stamped aluminum foil lunch boxes to improve work efficiency.

[0021] In this embodiment, through Figure 1-2 As shown, the discharging assembly includes a fixed plate 8 slidably disposed in the moving die 7. A plurality of limiting rods 9 are fixed on the fixed plate 8. Each limiting rod 9 is slidably disposed on the lower plate 10. Each limiting rod 9 penetrates through the lower plate 10. A spring 11 is disposed on the outer ring of each limiting rod 9. One end of each spring 11 is fixed on the fixed plate 8, and the other end of each spring 11 is fixed on the lower plate 10. The lower plate 10 is fixed on the output end of the second cylinder 12. The second cylinder 12 is fixed in the operating table 1. When the moving die 7 descends to punch the aluminum foil in the fixed die 3, the moving die 7 descends to squeeze the fixed plate 8, and the fixed plate 8 descends to squeeze the spring 11, and then the punching is completed. After the punching is finished, the spring 11 drives the fixed plate 8 to reset, and the second cylinder 12 pushes the lower plate 10 to drive the fixed plate 8 to push out the punched aluminum foil lunch box, so that the upper side surface of the fixed plate 8 is aligned with the horizontal plane of the operating table 1.

[0022] In this embodiment, through Figure 1-2 As shown, a limiting plate 13 is fixed in the operating table 1. The limiting plate 13 is located in the fixed die 3. The limiting plate 13 is the lowest position for the fixed plate 8 to descend, avoiding the fixed plate 8 continuing to descend and causing huge pressure on the lower plate 10, thereby damaging the second cylinder 12.

[0023] In this embodiment, through Figure 1-2 As shown, the material receiving assembly includes a push plate 14. A rotating column 15 is rotatably installed on both sides of the push plate 14. The two rotating columns 15 are respectively fixed on a rotating plate 16. The middle positions of the lower sides of the two rotating plates 16 are respectively fixed on the output ends of a second motor 17. The two second motors 17 are both fixed on the operating table 1. A stacking assembly is installed on the operating table 1. When the punched aluminum foil lunch box is pushed out to the upper side surface of the operating table 1, the second motor 17 drives the rotating plate 16 to rotate, and the rotating plate 16 drives the rotating column 15 to rotate, thereby driving the push plate 14 to move. At this time, the push plate 14 pushes the aluminum foil lunch box away from the fixed plate 8 and pushes it into the stacking assembly.

[0024] In this embodiment, through Figure 1-2As shown, two clamping plates 18 are slidably mounted on the push plate 14. The two clamping plates 18 are fixedly connected by a fixing block 19. A chute 20 matching the fixing block 19 is formed on the operating table 1. The clamping plates 18 are slidably arranged on the chute 20 through the fixing block 19. The movement track of the push plate 14 is an elliptical track. Pushing the aluminum foil lunch box will cause position deviation. When the push plate 14 moves, it drives the clamping plates 18 to move. The clamping plates 18 can only move in the front-back direction along the chute 20 through the cooperation of the fixing block 19 and the chute 20. Therefore, when the push plate 14 drives the clamping plates 18 to move, the clamping plates 18 move back and forth along the chute 20, while the push plate 14 moves in the left-right direction, ensuring that the clamping plates 18 can push the aluminum foil lunch box straight and smoothly enter the stacking component.

[0025] In this embodiment, through Figure 1-2 As shown, the stacking component includes an aggregate chute 21 formed on the operating table 1. The end of the aggregate chute 21 is provided with an aggregate frame 22 fixed to the operating table 1. A lifting plate 23 that can move up and down is arranged in the aggregate frame 22. A slot is formed on the aggregate frame 22. The lifting plate 23 passes through the aggregate frame 22 and is slidably arranged on the aggregate frame 22 through the slot. An aggregate plate 24 is slidably arranged on the lifting plate 23. A pull plate 25 is fixed on the aggregate plate 24. A handle 26 is fixed on the pull plate 25. The upper side opening of the aggregate chute 21 is long, and the lower side outlet is narrow, which can align the aluminum foil lunch box entering the aggregate chute 21 and make the aluminum foil lunch box enter the aggregate frame 22. The aluminum foil lunch box enters the aggregate frame 22 and lands on the aggregate plate 24. When a certain number of aluminum foil lunch boxes are stacked on the aggregate plate 24, the staff can pull the pull plate 25 and the aggregate plate 24 through the handle 26 to take away the aluminum foil lunch box.

[0026] In this embodiment, through Figure 1-2 As shown, two threaded rods 27 are arranged on the operating table 1. One of the threaded rods 27 is fixed to the output end of a third motor 28, and the other threaded rod 27 is rotatably mounted on the operating table 1. Synchronous wheels 29 are fixed on both threaded rods 27. The two synchronous wheels 29 are both connected by a synchronous belt 30. The lifting plate 23 is threadedly connected to the two threaded rods 27. A threaded groove meshing with the threaded rods 27 is formed on the lifting plate 23. When the third motor 28 operates, it drives one threaded rod 27 to rotate. This threaded rod 27 drives the other threaded rod 27 to rotate through the cooperation of the synchronous wheels 29 and the synchronous belt 30. The two threaded rods 27 rotate to drive the lifting plate 23 to move, and the lifting and lowering of the lifting plate 23 is controlled by controlling the forward and reverse rotation of the third motor 28.

[0027] In this embodiment, through Figure 1-2As shown, an infrared sensor 31 is installed on the inner side wall of the aggregate frame 22. The selected signal is the E3JK-R4M1 infrared sensor. The infrared sensor 31 is installed at a position above the aggregate frame 22, and the vertical distance from the upper side of the lifting plate 23 at the initial position is the height of an aluminum foil lunch box.

[0028] When the present utility model is in use, first, the first cylinder 6, the second cylinder 12, the second motor 17, the third motor 28, and the infrared sensor 31 are all connected to an industrial industrial control computer through wires. The first cylinder 6 is controlled to drive the moving die 7 to punch the aluminum foil in the fixed die 3, and then the punched aluminum foil lunch box is pushed out by the discharging assembly. Then, the second motor 17 is controlled to drive the push plate 14 to push the aluminum foil lunch box into the aggregate groove 21 and slide onto the aggregate plate 24 in the aggregate frame 22. When the aluminum foil lunch box blocks the infrared sensor 31, information is transmitted to the industrial industrial control computer. The industrial industrial control computer sets the time for the infrared sensor 31 to be blocked to five seconds. After more than five seconds, the third motor 28 is controlled to drive the lifting plate 23 to descend a set distance (the distance can be 5 cm) so that the infrared sensor 31 is no longer blocked. The aggregate plate 24 is close to the lower opening of the aggregate groove 21, which can prevent the aluminum foil lunch box from flipping in the air when entering the aggregate frame 22, thus causing the stacked aluminum foil lunch boxes to be placed unevenly.

[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
