A process for preparing a heatable aluminum foil packaging lunch box with application number CN202010876648.0 includes a base plate, a workbench, a mounting frame, a stamping device and a feeding device.

A notch is arranged at an angle end of one side of the angle plate 2, and one side of the notch is a movement front to avoid collision with the ring of the gear ring 5 and improve the movement range. A gear ring 5 is sleeved on the outside of the angle plate 2. The teeth of the gear ring 5 are arranged on the inner wall of the ring. The ring of the gear ring 5 is movably connected with a gear 6. The outer surface of the wheel 6 is meshed with a ruler plate 7, and the outer surface of the ruler plate 7 is fixedly connected to the outer surface of the angle plate 2. The body of the angle plate 2 is provided with a through slide groove 8, and the inner part of the slide groove 8 is movably connected with a pin rod 9. At least two pin rods 9 are provided inside each slide groove 8 to limit and guide the movement of the angle plate 2. One end of the pin rod 9 is fixedly connected to the outer surface of the mold base 1. The outer surface of the gear ring 5 is fixedly connected to a swivel 10.

The outer surface of the swivel 10 is embedded in the outer surface of the mold base 1 for rotation connection, and the outer surface of the gear ring 5 is fixedly connected to a lever 11.

[0043] In this embodiment, the gear ring 5 is driven by the lever 11 to rotate, and the gear 6 is respectively engaged with the gear ring 5 and the ruler plate 7, so that the ruler plate 7 pushes the four corner plates 2 to move synchronously. During the movement of the corner plates 2, the pin rod 9 slides inside the slide groove 8 to limit and guide the movement of the corner plates 2. At the same time, after the corner plates 2 move, a mold cavity can be formed by the space surrounded by the waist edge to facilitate the forming of the lunch box.

The outer surface of the fan 342 is fixedly connected to the inside of the ring of the frame 344. The outer surface of the frame 344 is fixedly connected to a push-pull rod 345. The push-pull rod 345 is made of an electric push rod and is electrically connected to an external control circuit. The outer surface of the push-pull rod 345 is fixedly connected to the inside of the inner cavity 341. The outer surface of the frame 344 is fixedly connected to a slide column 346. The slide column 346 is made of the same material as the frame 344. By filling the air hole 343 below, it is convenient for the punch 33 to punch the aluminum foil raw material. The outer surface of the slide column 346 is slidably connected to the inner cavity 341 and the air hole 343 respectively.

[0049] In this embodiment, when the lunch box is stuck outside the punch 33, or the mold base 1 needs to be cleaned, the output end of the push-pull rod 345 retracts to drive the square frame 344 to rise inside the inner cavity 341, thereby driving the sliding column 346 to follow the movement and slide out from the air hole 343, and then the fan 342 works to drive the air inside the inner cavity 341 to be discharged to the outside through the ring of the square frame 344 and the air hole 343, so that the stuck lunch box can be blown off and the waste chips on the mold base 1 can be cleaned, and at the same time, air heat dissipation of the mold base 1 and the angle plate 2 can be achieved on the outside.

[0055] In this embodiment, when it is necessary to control the adjustment of the angle plate 2 through the lever 11, the linear motor 442 slides along the slide rail 441. Through the cooperation of the fixed frame 445, the I-wheel 446 and the sliding sleeve 447, the lever 11 can be moved to drive the gear ring 5 to rotate, thereby driving the angle plate 2 to move, and at the same time, the connecting plate 444 pushes the sliding end of the sliding rheostat 443 to move synchronously, so as to adjust the power of the liquid pump 46 and the semiconductor refrigeration plate 43, so that the heat dissipation efficiency provided by the power is proportional to the volume of the lunch box, so as to improve the heat dissipation effect when producing lunch boxes of different specifications.
