Description

Technical Field

[0001] The invention relates to the technical field of plate chains, in particular to an anti-jamming plate chain mechanism. Background Art

[0002] Plate chain is a chain transmission device widely used in industrial fields such as material transportation and lifting. It is usually composed of a series of interconnected chain plates and pins. The chain plates have a certain strength and shape to carry materials or withstand tension, and the pins ensure that the chain plates can rotate flexibly to achieve the circular motion of the chain. There is a risk of the plate chain being stuck during operation. The emergency stop of the plate chain causes the current of the drive motor to increase, causing the motor to burn out and causing great losses. The anti-stuck plate chain mechanism can solve the above problems.

[0003] A Chinese patent discloses an anti-stuck plate chain mechanism (authorization announcement number CN220396407U). This patented technology realizes power transmission between the driving wheel and the driven sprocket by a connecting pin. By setting the size of the first shear groove on the connecting pin, it is ensured that the driving wheel transmits appropriate power to the driven sprocket and then to the plate chain assembly. When the movement of the plate chain assembly is blocked, the connecting pin will be cut off at the first shear groove, thereby cutting off the power connection between the driving wheel and the driven sprocket, effectively preventing the plate chain mechanism from getting stuck. However, the above-mentioned anti-stuck plate chain mechanism prevents jamming by cutting off the transmission gear, but the plate chain will stop running after the transmission is cut off, affecting the stability of the plate chain transmission and the working efficiency of the plate chain. After cutting off, the transmission gear needs to be replaced. The convenience of replacement is low and the maintenance cost is high. The plate chain transition is connected by rivets, and the assembly efficiency of the plate chain is low. Therefore, those skilled in the art provide an anti-stuck plate chain mechanism to solve the problems raised in the above-mentioned background technology. Summary of the invention
