Technical Field

[0001] The utility model relates to the technical field of demoulding equipment, in particular to a demoulding device for processing disposable lunch boxes. Background Art

[0002] Disposable fast food boxes have shifted from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes were eliminated because they were not resistant to high temperatures and the production process caused damage to the environment. They were replaced by plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degradable lunch boxes, etc. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, simple production and relatively low cost, so it has become the mainstream material for manufacturing disposable fast food boxes. PP polypropylene has mechanical and thermal properties and is suitable for meal packaging. Plastic disposable lunch boxes use injection molds in production. After the injection mold is completed for the disposable fast food box, it needs to be manually taken out of the mold cavity and placed on the conveyor belt for transportation to the next processing step, which consumes manpower and physical strength.

[0004] The above patent discloses a demoulding device for processing disposable lunch boxes, which realizes the demoulding of the disposable lunch boxes by driving the suction cup to move up, down, left and right, and cooperating with the provided negative pressure pump to provide suction power. However, it still has some shortcomings:

[0005] The method of using only a suction cup to suck and move the disposable lunch box for demoulding is prone to cause the entire lunch box mold to move when the lunch box mold and the disposable lunch box are tightly pressed together, resulting in ineffective separation and unsatisfactory demoulding stability.
