Description

Technical Field

[0001] The utility model relates to the technical field of personal care product manufacturing equipment, in particular to a bottle bottom coding mechanism. Background Art

[0002] In current personal care products, bottles are often used for packaging. For example, shampoo, shower gel and other care products need to be packaged in bottles. In order to let consumers know the production and manufacturing of the products, information such as the date is often sprayed on the bottles to meet market regulations and consumer information transparency requirements.

[0003] In order to prevent the traceability code from affecting the aesthetics of the bottle, the factory often sprays it on the bottom of the bottle. For the sake of aesthetics, the shape of the bottle is often not a regular shape. Some bottles have a slope on one side or a taper on the whole. This results in a smaller contact area between the conveyor belt of the clamping mechanism and the bottle during transportation, resulting in unstable clamping and tilting of the bottle during transportation, thus affecting the spraying effect of the date.

[0004] The utility model is made based on the above situation. Utility Model Content
