Description

A kind of turning machine with floating buffer device

technical field

The utility model relates to a steering conveyor, in particular to a turning machine with a floating buffer device.

Background technique

The turning machine is a steering mechanism on the product conveyor line, which is used to change the state of the product on the conveyor, for example, through its operation, the product can be turned from horizontal to vertical to enter the next process flow. When the flap starts and stops, an impact will be generated, so the characteristics of this gap flip movement require static positioning and dynamic buffering. In the prior art, a positioning pin is installed at the bottom of the power output head, and a rubber vibration isolating ring is embedded in the positioning hole, and the positioning pin is used for static positioning, and the rubber vibration isolating ring is used to solve the problem of buffering small impacts. However, the compression deformation of the rubber vibration isolation ring is limited, the rubber is also prone to aging and failure, and the cushioning force is small, while the positioning pin shaft is not rigid enough and is easily deformed after being impacted. The impact is damaged, and problems such as positioning deviation or failure occur, which cause the receiving end of the turning machine to be upturned and block the product, causing the steering to fail or the turning machine to stop running, which seriously affects the effective operation rate of the production line.
