Description

Technical Field

[0002] There are many kinds of bottle-shaped products in the medical device, food, daily chemical and other industries. These bottle-shaped products need to convey the formed bottle body during the production process. When conveying the bottle body, the bottle body is placed above the conveyor belt and driven by the conveyor belt to be transported. Since the bottle body has a certain height and a high center of gravity, a clamping structure for firmly supporting the bottle body is required to prevent the bottle body from tipping over on the side of the conveyor belt during bottle conveying. The lateral clamping structure is used to firmly clamp and support the bottle body to ensure that the bottle body remains upright and is stably conveyed by the conveyor belt.

[0003] The clamping structure on the top of traditional conveyor belts is mostly a rigid clamping structure, which clamps and supports the bottle body through a rigid clamping block structure. However, in actual production, packaging bottles often have various shapes and specifications. The clamping groove formed by the rigid clamping block has a fixed size and can only clamp bottles of specific specifications. When clamping bottles of non-standard specifications, the bottle body is easily deformed and damaged due to the squeezing of the clamping block. It is difficult to stably clamp and support packaging bottles of various shapes and specifications. It has high limitations in use and lacks certain versatility and flexibility of use.
