Description

Technical Field

[0001] The present invention belongs to the technical field of plastic lunch boxes, and particularly relates to an automatic reverse lunch box collection device. Background Art

[0002] Plastic lunch boxes have outstanding barrier properties. On the premise that the thickness of the plastic lunch box is sufficient, they can basically completely block gases and moisture. Therefore, plastic lunch boxes are often used to make lunch boxes. Plastic lunch boxes not only meet the national food container hygiene standards, but more importantly, they conform to the international environmental protection trend and bring great convenience to people. Currently, plastic lunch boxes are all rapidly produced and manufactured through production lines, and the last process of production is to collect the plastic lunch boxes.

[0003] At the same time, due to their light weight, durability, easy cleaning and other characteristics, plastic lunch boxes are widely used in the modern catering industry. Raw material preparation is the first step in plastic lunch box production, mainly including the procurement, inspection and storage of the required raw materials; the raw materials are usually plastic materials such as polypropylene (PP) and polyethylene (PE), and it is necessary to ensure that they meet the production requirements, such as purity, viscosity, stability, etc.; according to the product formula and process requirements, the raw materials are proportioned in a certain ratio, and the raw materials are heated and stirred by a kneader to make them evenly mixed and reach a certain viscosity. Injection molding is the core step in plastic lunch box production. The molded plastic lunch box needs to go through a cooling process to solidify it and make it have a certain strength and hardness. In order to improve the durability and aesthetics of plastic lunch boxes, surface treatment is usually required. After the plastic lunch boxes are produced, quality inspection needs to be carried out on the plastic lunch boxes, and defective products are removed from the produced products; during the production process, defective products are often generated due to problems with raw materials, production processes, equipment or operations, and these defective products cannot enter the market.
