Description

Plate chain conveyor chain return carrier roller drawing mechanism

Technical Field

The utility model relates to a plate chain conveyor, in particular to a pull mechanism for a chain returning carrier roller of the plate chain conveyor.

Background

Some plate chain conveyors are compact in structure, when the plate chain conveyor is not high and is integrally thin, maintenance personnel cannot enter the rack to replace and maintain a chain returning carrier roller in the plate chain conveyor, the plate chain needs to be removed for maintenance, and the maintenance mode wastes time and labor and also influences the normal work of equipment. For example, the utility model patent document with publication number CN101077738 discloses a reciprocating plate chain conveyor for a fixed container inspection system, which comprises a driving device, a head wheel device, a frame and a tail tensioning device. The frame is connected with the head wheel device and the tail tension device, and the power of the driving device is transmitted to the head wheel device. Chain wheels are arranged on two sides of a transmission shaft of the head wheel device and the transmission shaft of the tail tensioning device, and a traction chain is embedded in each chain wheel. The structure is characterized in that the traction chain is arranged in an upper bracket and a lower bracket which are connected with the frame and are arranged in parallel. The whole tensioning process of the traction chain ensures that the lengths of the traction chain at the upper chain and the lower chain are equal, thereby realizing the free reciprocating transmission of the plate chain conveyor. In the above conveyor, the traction chain is provided with a bedplate, and each section of traction chain and the bedplate can be designed into a whole independently. By adopting the structure, the upper chain and the lower chain in the plate chain conveyor have the same length, the upper bracket is parallel to the lower bracket, the traction chain is tensioned in the whole process, the difference of loose edges and tight edges does not exist, and the plate chain conveyor cannot generate 'chain stacking' when running in the reverse direction. The traction chain is horizontally cut into the lower bracket under the traction of the head wheel device or is horizontally cut into the tail wheel by the lower bracket, the traction force borne by all chain links in a transmission period is basically unchanged, and the transmission direction is changed only by the change of the rotation direction of the driving device, so that the plate chain conveyor can freely reciprocate. Above-mentioned technical scheme just has the bearing roller on the lower carriage and changes the difficult problem.
