The automation of the lunch box machine and its devices are briefly introduced as follows:

1. Work flow: paper sucking → brake paper → rapid paper feeding → heating → entering molding mold → stable molding → finished product → finished product automatic stacking. Because the whole machine uses the air valve control, so must start the air pump first before the work and has certain air pressure condition.

2. Feeding system: the paper must be placed in the paper slot in a relatively smooth way, and the upper part of the paper slot is provided with a content detection device, which requires the paper to have a certain amount of reserves. If the paper is short, it will give an alarm automatically, and the machine will stop automatically when it is lower than the content level limit.

3. Safety protection device: In order to prevent accidents, an infrared protection controller is set at the bottom of the forming mold of the working table. When there is foreign matter, the forming mold cannot drop and an alarm signal is sent.

4. Operation mode: The lunch box machine is fully automatic. When the stacking height of paper in the paper slot is greater than the required value, the machine can press the start button under normal condition and the machine can work fully automatically.

5. Record and output: The product quantity can be preset and displayed at any time.
