Description

[Technical field]

[0001] The invention relates to the technical field of plastic bottle processing, in particular to the technical field of environmentally friendly and recyclable plastic bottle scraping equipment. [Background technology]

[0002] Multilayer barrier bottles are a common type of bottles produced by hollow blow molding machines. In order to better isolate oxygen or moisture to improve the quality preservation effect of multilayer barrier bottles on the liquid in the bottle, the middle layer of the multilayer barrier bottles currently used is generally EVOH or PA. In order to ensure the sealing of multilayer barrier bottles using EVOH or PA as the middle layer, the mouth of the multilayer barrier bottle must be scraped flat first, so that the middle layer of EVOH or PA material is exposed from the bottle mouth, and then the bottle mouth is sealed with sealing resin. At present, the mouth of the multilayer barrier bottle blow-molded by the hollow blow molding machine is manually scraped. This manual scraping operation method not only has high labor intensity for workers, but also has low work efficiency. [Summary of the invention]
