[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 6 As shown in this embodiment, a driving device for picking up and placing square lunch boxes includes a rotating pot support plate 1, a steel wire rope 2, a food box rack 3, a main connecting rod 4, a secondary connecting rod 5, and a square steel rotating shaft 6. A wok placement position 7 is provided in the middle of the rotating pot support plate 1. There are two food box racks 3, which are located on both sides of the wok placement position 7. One end of the secondary connecting rod 5 is hinged to the rotating pot support plate 1, and the other end of the secondary connecting rod 5 is hinged to the upper end of the food box rack 3. The square steel rotating shaft 6 is located in front of the rotating pot opening support plate 1. One end of the main connecting rod 4 is fixed on the square steel rotating shaft 6, and the other end of the main connecting rod 4 is hinged to the middle of the vegetable box frame 3. The upper end of the rotating pot opening support plate 1 is hinged with opening and closing pull plates 8 on both sides. The outer side of the opening and closing pull plates 8 is connected to the steel wire pull rope 2. The inner side of the opening and closing pull plates 8 is equipped with opening and closing bearings 9. The vegetable box frame 3 is provided with opening and closing holes 10, and the opening and closing bearings 9 are located in the opening and closing holes 10.

[0027] During the cooking process, the steel wire rope 2 pulls the opening and closing rotating plate 8 to rotate outward at a certain angle. The opening and closing bearing 9 on the inner side of the opening and closing rotating plate 8 pulls the two food box racks 3 outward within the opening and closing hole 10 on the food box rack 3. The square food box that was originally held by the two food box racks 3 will fall into the rotating pot opening rack 1 to wait for heating and cooking.

[0028] When the cooking is finished and the square lunch box needs to be removed, the steel wire rope 2 pushes the opening and closing rotating plate 8 back to the middle of the rotating pot mouth support plate 1. The opening and closing bearing 9 no longer clamps the outside of the opening and closing hole 10, so that the food box racks 3 on both sides of the square lunch box can move closer to the middle and clamp the square lunch box. Then the square steel rotating shaft 6 rotates, and the main connecting rod 4 pulls the food box rack 3 off the rotating pot mouth support plate 1. Due to the restriction of the secondary connecting rod 5, the food box rack 3 will change from an inclined state to a horizontal state, straightening the inclined square lunch box and removing it.

[0029] An opening and closing guide rivet 11 is fixed at the upper end of the rotary pot mouth support plate 1. An opening and closing arc-shaped guide groove 12 is provided on the opening and closing pull rotary plate 8. The opening and closing guide rivet 11 moves in the opening and closing arc-shaped guide groove 12. The opening and closing guide rivet 11 serves as a structure to guide the opening and closing pull rotary plate 8 to rotate, ensuring the trajectory of the opening and closing pull rotary plate 8.

[0030] A stainless steel tension spring 13 connects the two food container holders 3. Without the restriction of the opening and closing bearing 9, the stainless steel tension spring 13 will bring the two food container holders 3 together to hold the square food container.

[0031] A stainless steel rotating tube 14 is connected between the secondary connecting rods 5. A hollow guide sleeve 15 is fixed at the upper end of the food container rack 3. The hollow guide sleeve 15 is sleeved on the stainless steel rotating tube 14. The hollow guide sleeve 15 can slide on both ends of the stainless steel rotating tube 14 to guide the food container rack 3 to be stably clamped on both sides of the square food container.

[0032] An electric push rod 16 is installed below the rotating pot rim plate 1. A rotating push-pull component 17 is hinged to the drive end of the electric push rod 16. A push-pull main drive connecting rod 18 is hinged between the front end of the rotating push-pull component 17 and the square steel rotating shaft 6. The electric push rod 16 provides the power to pick up and put down the square lunch box. When the rotating push-pull component 17 is driven to move forward, the square steel rotating shaft 6 is rotated through the hinge of the push-pull main drive connecting rod 18, thereby driving the main connecting rod 4 to pull the food box rack 3 back onto the rotating pot rim plate 1 and place the square lunch box. When the rotating push-pull component 17 is driven to move backward, the square lunch box is picked up and removed.

[0033] The detachment push-pull component 17 is equipped with a deep groove ball bearing 19. The electric push rod 16 is swung forward with a pull wire hanger 20. The deep groove ball bearing 19 is inserted into the pull wire hanger 20. The end of the steel wire rope 2 that is far from the opening and closing pull plate 8 is fixedly connected to the pull wire hanger 20. When the detachment push-pull component 17 is pushed forward, the deep groove ball bearing 19 is inserted into the pull wire hanger 20. While rolling and contacting, it pushes the pull wire hanger 20 to swing forward, thereby pulling down the steel wire rope 2, which in turn causes the opening and closing pull plate 8 to swing outward.

[0034] A hatch 21 is provided in front of the rotating pot support plate 1. The lower end of the hatch 21 is hinged to the outer equipment. A hatch connecting rod 22 is hinged between the middle of the hatch 21 and the main connecting rod 4. When the main connecting rod 4 drives the food container rack 3 to move out, the hatch 21 is controlled to flip downward around the outer equipment through the hatch connecting rod 22, and the food container rack 3 moves out with the square food container. When the main connecting rod 4 drives the food container rack 3 to retract, the hatch 21 is also controlled to flip upward around the outer equipment through the hatch connecting rod 22, so as to realize the cooking with the door closed.

[0035] A diffuse reflection photoelectric sensor 23 is installed between the hatch 21 and the square steel rotating shaft 6. The diffuse reflection photoelectric sensor 23 is used to sense whether there is a square lunch box on the food box rack 3.

[0036] The upper inner side and the lower inner side of the food container rack 3 are integrally formed with food container rack hooks 24. The food container rack hooks 24 on the four corners can be used to hook the square food container for easy removal and placement.

[0037] It should be stated that the above specific embodiments are merely preferred embodiments of the present invention and the technical principles applied thereto. Within the scope of the technology disclosed in the present invention, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of the present invention.
