Description

Technical Field

[0001] The utility model relates to the technical field of vacuum capping machines, in particular to a tightening structure for bottle capping. Background Art

[0002] Vacuum capping machine is a kind of equipment used for vacuum capping of glass bottles and tinplate screw caps. It is widely used in bottle packaging products. By sealing the bottles in a vacuum chamber, it ensures that there is no air in the bottles, thereby improving the shelf life of the products in the bottles.

[0003] During the use of the vacuum capping machine, in order to facilitate the fixation of the glass bottles, a lower mold base is usually required, such as the lower mold base provided in a vacuum capping machine proposed in Chinese patent CN214243745U; during use, the lower mold base is replaced to adapt to glass bottles of different specifications and sizes to load the glass bottles, but after the lower mold base is loaded with the glass bottles, there will be a slipping problem during the capping process; for this reason, the workshop has made improvements to the lower mold base, and designed a rebound component on the lower mold base. When the rebound component is under pressure, the rebound component will tighten the glass bottle in the lower mold base, thereby improving the fixing effect of the glass bottle; in order to cooperate with the use of the rebound component, it is necessary to design a tightening structure to realize the pressure action of the rebound component.
