Manufacturing method of aluminum foil and tinfoil heat preservation lunch box

Abstract

The invention relates to a manufacturing method of an aluminum foil and tin foil heat preservation lunch box, and an aluminum foil and tinfoil heat preservation lunch box manufacturing device is used and comprises a mounting bottom plate, a supporting column, a supporting frame, a conveying mechanism, a compacting mechanism and a stamping mechanism. The aluminum foil and tinfoil heat preservation lunch box manufacturing device can solve the following problems: in the manufacturing process of the the aluminum foil and tin foil heat preservation lunch box, aluminum foil and the tinfoil are difficult to be tightly attached and compacted in the conveying process, the structural toughness of the aluminum foil and tinfoil meal box in the stamping process is cannot be improved, the aluminum foil and tinfoil meal box is difficult to generate multi-position and multi-angle bending deformation through the abutting effect in the stamping forming process, the structural toughness of the aluminum foil and tinfoil heat preservation meal box cannot be further improved, and the aluminum foil and tinfoil meal box clamped in a stamping cavity is more difficult to fall off through the circumferential vibration beating effect after stamping forming is finished, and continuous stamping operation is not facilitated.

Description

technical field [0001] The invention relates to the field of lunch box preparation, in particular to a production method of an aluminum foil tin foil heat preservation lunch box. Background technique [0002] Aluminum foil lunch box is a kind of tableware that is widely used. The thickness of the aluminum foil lunch box is generally between 0.03mm and 0.20mm, which can be divided into two types: wrinkled and wrinkle-free. It can also be divided into two types: disposable and reusable. It is often called tin foil lunch box in China. In fact, it is made of 3 series or 8 series as the raw material of aluminum ingots. The production process of special equipment and mold one-time automatic cold stamping forming can improve the deformation resistance of the lunch box during transportation and storage through the double-layer design of aluminum foil and tin foil, and at the same time increase the food insulation performance to a certain extent.

Problems solved by technology

[0004] 1) Because the aluminum foil tin foil lunch box is often in the shape of a roll for the convenience of transportation and storage before stamping, it needs to be unfolded during the stamping process. Due to the influence of its own toughness, the aluminum foil tin foil often has a certain curvature after unfolding Bending, resulting in different shapes and sizes of lunch boxes punched out by different batches of lunch boxes during the stamping process, which increases the non-defective rate of lunch box preparation, and it is difficult to achieve synchronous delivery of aluminum foil and tin foil rolls Collect the remaining material on the side after the stamping is completed to reduce the labor intensity of manual operations
