Description

Technical Field

[0001] The invention relates to the field of production machinery, in particular to an equally divided distance adjusting device. Background Art

[0002] In the field of production machinery, such as filling machinery, packaging machinery and other assembly line operations, the products conveyed from the previous process assembly line are generally close to each other, but due to the needs of subsequent processes, such as the filling process, due to the separation setting of the filling head, the conveyed bottle body needs to be set to a spacing that matches the filling head. Although there is a disc-type distance adjustment device, that is, a disc is set on the conveyor line, and notches matching the bottle body are set at intervals on the disc, the purpose of distance adjustment is achieved by controlling the spacing between adjacent notches. The assembly line set up in this distance adjustment method has faster speed and higher efficiency, but this disc-type adjustment device is more suitable for cylindrical bottles, and its adaptability has certain limitations. Moreover, the accuracy of this type of distance adjustment device is relatively poor. When filling, due to accuracy reasons, the filling head touches the bottle body when it is extended, which will not only cause the bottle body to tip over and affect the working stability of the entire assembly line, but also cause damage to the filling head, which requires shutdown for maintenance, affecting the entire processing and production process.
