Abstract

The invention discloses a manufacturing method of an impact-resistant food packaging tin, and relates to the technical field of food packaging tin processing, in particular to the manufacturing method of the impact-resistant food packaging tin, which comprises the following steps: 1, selecting an aluminum plate or an aluminum alloy plate; 2, punching the aluminum plate and the aluminum alloy plate into an aluminum wafer or an aluminum alloy wafer by adopting a punching machine; 3, drawing and shaping: drawing the aluminum wafer and the aluminum alloy sheet into a cylinder through a drawing die; 4, fixing and forming: fixing through an arch bottom forming die, and punching wedged shapes which are mutually matched on the peripheries of the sides, close to each other, of the inner cylinder and the outer cylinder; 5, reinforcing ribs are poured in the gap between the inner cylinder and the outer cylinder; and 6, welding and edge sealing are conducted on the gap between the inner cylinder and the outer cylinder through the aluminum alloy circular ring. The tank body is of a double-layer structure, and the reinforcing ribs are poured in the gaps of the double layers, so that the fireproof and heat-insulating performance of the tank body is improved while the tank body has compression impact resistance.

Description

technical field [0001] The invention relates to the technical field of food packaging jar processing, in particular to a method for manufacturing an impact-resistant food packaging jar. Background technique [0002] Food needs to be packaged during the process of processing, transportation, storage, sales, and consumer use. Food packaging containers usually refer to packaging containers that are in direct contact with food, that is, inner packaging containers. Foods that are packaged (usually in a processing plant) using packaging containers or packaging materials are called packaged foods, and existing food packaging containers are often cans. [0003] However, when the existing food packaging cans are used for transportation, due to the low strength of the tank body, the food packaging cans often appear deformed during transportation and use. Good protection effect, and the existing food packaging cans have poor fireproof and heat insulation effects, so we propose a manu...
