Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purification structure for forming a food packaging box. Background Art

[0002] A packaging box generally consists of a box body and a box cover. Both the box body and the box cover can be processed using an automatic molding machine. The loading of the automatic molding machine requires manual operation, and in order to intuitively observe the operation of the equipment, the processed parts are directly exposed to the air. The processing process is to transport the plastic into the equipment, heat the plastic raw materials, press them into shape with a mold, and then cut them to obtain a complete plastic box cover.

[0003] When using an automatic forming machine for the packaging box cover, the plastic raw materials need to be heated and shaped, and then the heated and shaped raw materials are transported to the cutting position for cutting.

In this process, the heating and softening of the plastic will produce some pungent odors, which seriously affect the working environment. At the same time, long-term inhalation of the odor produced by the heating of the plastic will also have a certain impact on the health of the staff. Utility Model Content
