Description

Technical Field

[0001] The utility model relates to the technical field of AGV, and particularly relates to an AGV auxiliary feeding and discharging transmission mechanism. Background Art

[0002] In the warehousing industry, in order to facilitate the transportation of items to designated positions, AGV carriers are usually used. When the AGV carrier delivers the items to the designated position, in order to assist the items in feeding and discharging, a transmission mechanism is usually installed on the AGV carrier to transmit the items. The existing transmission mechanism usually consists of a fixed frame and a conveyor belt.

[0003] For example: The utility model with the application number CN202222541670.7 discloses an AGV transportation transmission structure, which specifically includes a guiding vehicle body. A storage device is arranged above the guiding vehicle body. The storage device includes a plurality of axles arranged horizontally. A transmission component for driving the axles to rotate is arranged inside the guiding vehicle body. One of the pulleys includes two belt discs, and the other pulley includes a rotating disc. One of the belt discs and the rotating disc are close to each other and a speed reduction mechanism is arranged between them. The AGV transportation transmission structure provided by the utility model, through the arrangement that a storage device is arranged above the guiding vehicle body and a transmission device for driving the storage device to transport is arranged inside the guiding vehicle body, and the transmission device is connected to the connecting shaft between the wheels, when the guiding vehicle body moves to transport products, the wheels roll and drive the storage device to transport products through the action of the transmission device.

[0004] However, for the current traditional transmission mechanism, during the long-term use of the conveyor belt, since the transmission mechanism is constantly in contact with various items, it is easy for impurities on the items to adhere to the conveyor belt, increasing the frictional resistance during the transmission process, reducing the transmission efficiency of the conveyor belt, and at the same time, the attached dust is also easy to cause wear on the surface of the conveyor belt, making it inconvenient to use. Summary of the Utility Model

[0005] In view of this, the present utility model provides an AGV auxiliary feeding and discharging transmission mechanism, which has a cleaning brush and a cleaning scraper capable of automatically cleaning the dust adhering to the surface of the conveyor belt during the process of transporting articles. As the conveyor belt drive shaft rotates, it will drive the cooperation of the first pulley and the second pulley to drive the transmission rotating shaft to rotate, and drive two control worm wheels engaged therewith to rotate through two control worms. During the rotation of the control worm wheels, the cleaning brush will be driven to rotate through the fixed rotating shaft to clean the dust outside the conveyor belt. During the rotation of the transmission rotating shaft, the first bevel gear will be driven to rotate, and the reciprocating screw will be driven to rotate through the engaged second bevel gear. During the rotation of the reciprocating screw, the guiding slider will be driven to reciprocate in the mounting frame, and during the reciprocating movement of the mounting frame, the cleaning scraper will be driven to reciprocate to scrape the stubborn dirt remaining on the conveyor belt.
