Description

Technical Field

[0001] The utility model relates to a hot end spraying device for a glass bottle and can, belonging to the technical field of glass production. Background Art

[0002] The main structure of glass is composed of Si-O covalent bonds, which determines that the mechanical properties of glass are brittle behavior, that is, there is no obvious macroscopic plasticity before breaking. In addition, there are a large number of microcracks on the surface and inside of the glass, which are very likely to expand under the action of external forces and environmental media, thus destroying the glass. In order to improve the strength of glass bottles and reduce friction between bottles, the outer surface of the glass bottles can be sprayed to enhance.

[0003] Glass bottle spraying can be divided into cold-end spraying and hot-end spraying. Cold-end spraying is generally performed by spraying the surface of the glass bottle with a spray gun during or after the annealing process of the glass bottle. For example, CN202010025696.9 discloses a cold-end spraying device and application for glass bottles and cans. Hot-end spraying of glass bottles and cans is a process of spraying specific materials on the surface of glass products through thermal spraying equipment. Generally, the outer surface of the glass bottle needs to be sprayed online at the hot end before the glass bottle enters the annealing kiln. For example, CN202020202494.2 discloses a hot-end spraying device for glass bottles, and CN202022747427.1 discloses a hot-end spraying device for beer bottles in a glass factory.

[0004] However, the existing hot-end spraying equipment for glass bottles mainly focuses on the stability of the glass bottles during the spraying process, but does not pay attention to the spraying uniformity, controllability and environmental protection. Summary of the invention
