Preparation process of heatable aluminum foil packaging lunch box

Abstract

The invention relates to a preparation process of a heatable aluminum foil packaging lunch box, which uses punch forming equipment. The punch forming equipment comprises a bottom plate, a workbench, amounting frame, a punching device and a material placing device, and the specific process flow for preparing the aluminum foil packaging lunch box by adopting the punch forming equipment is as follows: aluminum foil cutting, aluminum foil transferring, punch forming, edge pressing processing and discharging stacking; a punching device comprises a lifting air cylinder, a mounting block, a punchinghead and an edge pressing mechanism. According to the preparation process of the heatable aluminum foil packaging lunch box provided by the invention, an aluminum foil is punched and formed through the cooperation of the material placing device and the punching device, so that the flaky aluminum foil is made into a lunch box finished product, edge pressing treatment can be conducted on the lunchbox in the punching process at the same time, production equipment for edge pressing of the lunch box does not need to be additionally arranged, and in the aluminum foil moving process, the aluminum foil is guided and positioned in an air blowing mode, position deviation of the aluminum foil is avoided, and meanwhile aluminum foil deformation caused by extrusion is avoided.

Description

technical field [0001] The invention relates to the field of processing aluminum foil tableware, in particular to a preparation process for heatable aluminum foil packaging lunch boxes. Background technique [0002] Aluminum foil lunch box is a kind of tableware that is widely used. It uses 3 series or 8 series as aluminum ingot raw material, and is cold-rolled or hot-rolled into an aluminum foil parent roll with uniform thickness, smooth surface, no dust particles, and no peculiar smell. Special equipment and molds for one-time fully automatic cold stamping lunch boxes. [0003] Aluminum foil lunch boxes not only meet the national food container hygiene standards, but also adapt to the international environmental protection trend. It can be directly placed on a gas stove for heating and baked in a microwave oven without fear of danger, which brings great convenience to people. [0004] In the preparation process of aluminum foil lunch box, the most important step is to st...

AI Technical Summary

Problems solved by technology

[0005] (1) Since the material of the aluminum foil is relatively light and soft, if the aluminum foil is not positioned during the moving process, the aluminum foil will easily shift in position, which will affect the processing accuracy in the subsequent stamping process. However, if the traditional clamping, Positioning the aluminum foil by extrusion will leave indentations on the surface of the aluminum foil and even cause damage to the aluminum foil;

[0006] (2) After the aluminum foil is punched into the shape of the lunch box, it is usually necessary to press the edge of the lunch box, and it is necessary to add additional equipment dedicated to the edge to complete the edge pressing operation, which increases the input cost of the manufacturer, and due to the need Transferring the lunch box from the stamping equipment to the edge pressing equipment, the time interval between the two processes is long, which prolongs the overall working time
