Description

Variable damping rotating body device of pneumatic logistics transmission system

Technical Field

The utility model belongs to the transmission bottle transmission equipment in the medical appliance, in particular to a variable damping rotator device of a pneumatic logistics transmission system.

Background

The workstation and the diverter of the pneumatic logistics conveying system both comprise a rotator structure used for switching the direction of a pipeline or carrying a conveying bottle. The rotating body is a common direct current motor. The speed is reduced by the worm gear, the synchronous gear and the synchronous belt to drive the shaft of the rotating body. During the rotation of the rotating body, the encoder counts the rotation of the shaft of the rotating body, when the set value is counted, the motor is powered off, and the system considers that the rotating body rotates to the set direction. Because the motor moves axially, the gap between the shaft and the gear, the elasticity of the synchronous belt, the friction force is sealed between the rotating body and the top bottom plate, and the friction force is not uniform due to the problems of structure, assembly error and the like. When the rotating shaft rotates towards a certain direction, the friction force provided by the sealing ring can be rapidly reduced, and the rotating body can continue to slide for a certain distance under the action of inertia and even rebound. This results in the rotator not being aligned with the target direction in such a situation, and the pins and the ends of the pins, the bottom plate, and the edge of the rotator are jammed. Causing equipment damage or system failure. In actual use, the synchronous wheel only has slightly larger key slot clearance, and once the clearance is enlarged in the rotating process, the synchronous wheel needs to be replaced, so that waste is caused.
