Mess tin forming process

Abstract

The invention discloses a mess tin forming process. The mess tin forming process comprises the steps that S1, preheating is conducted, specifically, a plastic raw material plate is fed into a preheating mechanism at first, the upper face and the lower face of the plastic raw material plate are heated so that the plastic raw material plate can reach the pressing state, and the edges of the plastic raw material plate are not heated and adsorbed through a negative pressure system; S2, pressing forming is conducted, specifically, the preheated material plate is fed into a mold set, the mold set is provided with a plurality of forming molds arranged sequentially, the mold pressing depths are gradually increased, and the preheated material plate is gradually pressed and formed; S3, cutting is conducted, specifically, a mess tin formed through pressing is fed into a cutting mold, and excess materials of the mess tin formed through pressing are cut off; and S4, collection is conducted, specifically, the mess tin of which the excess materials are cut off is sucked away to be collected through a collection mechanism, and another negative pressure system is used for adsorption during collection. The mess tin forming process has the beneficial effects that the yield is high, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a molding process of a lunch box. Background technique [0002] In the catering industry, lunch boxes are very common supplies. In the production process of lunch boxes, they are usually formed by pouring or one-step pressing with molds. Using pouring, the thickness of the pouring is not easy to grasp, and there are cases of dissatisfaction with the pouring, and the thickness of the pouring is relatively thick. , waste materials, but the one-step pressing method is not easy to grasp the pressing force. When the force is too large, it is easy to break the original material, the scrap rate is high, and the cost is also wasted. [0003] The invention provides a molding process of the lunch box, which solves the above problems more practically, perfectly and conveniently. Contents of the invention [0004] The purpose of the present invention is to overcome the disadva...
