Abstract

The invention relates to a PET bottle blank processing assembly and a PET bottle blank processing method. The PET bottle blank processing assembly comprises a mold and a reverse blowing cleaning mechanism, wherein the reverse blowing cleaning mechanism is connected with the mold; an injection molding cavity is formed in the mold, a main air hole and an injection molding hole are formed in the positions, located at the two ends of the injection molding cavity, of the mold correspondingly, and the main air hole and the injection molding hole communicate with the injection molding cavity correspondingly to form a reverse blowing channel; the reverse blowing cleaning mechanism comprises a compressed air pipeline, a control air valve and a compressed air source; and the control air valve is installed on the compressed air pipeline, one end of the compressed air pipeline is installed and in communication with the main air hole, and the other end of the compressed air pipeline is connected with the compressed air source. The PET bottle blank processing assembly and the PET bottle blank processing method have the advantages of convenience in ash removal and rapidness.

Description

technical field [0001] The application relates to the field of PET preform processing, in particular to a PET preform processing component and a PET preform processing method. Background technique [0002] With the widespread promotion and use of PET plastic bottles, based on the consideration of market capacity demand and economic benefits, the number of cavities of PET preform molds is getting bigger and bigger, and the forming cycle is getting faster and faster. However, as the production time increases, the parts on the PET mold will slowly deposit the mixture of dust and oil-water produced by the PET material due to high temperature. These mixtures are thick and viscous, and will accumulate on the exhaust channels of the parts, which will eventually block the exhaust system of the PET preform mold. [0003] The blockage of the mold exhaust channel will lead to a large amount of waste products during continuous production. The current corresponding solution is to stop ...
