[0014] (III) Beneficial Effects

[0015] This utility model provides a belt replacement device for an annular belt scale, which has the following beneficial effects:

[0016] 1. This annular belt scale belt replacement device, through the setting of fixed components and moving components, in use, rotates the rotating block, which drives the locking pin to move. The locking pin moves and is pulled out from inside the locking block. After being pulled out, the servo motor is started, and the servo motor rotates, which drives the threaded rod to rotate. The rotation of the threaded rod causes the moving rod to move on the threaded rod, and the movement of the moving rod drives the moving frame to move, so that the moving frame separates from the roller. Thus, the belt body can be replaced without the need for the operator to disassemble the roller, reducing the difficulty and complexity of manual intervention and reducing the labor intensity of maintenance personnel.

[0017] 2. The belt replacement device for this annular belt scale, through the setting of the push component, causes the hydraulic rod to retract during replacement, making the belt body loose and facilitating replacement. After replacement, the hydraulic rod pushes the moving block to move, which in turn moves the roller, straightening the belt body. This ensures that the belt is in the correct position and tension during installation, avoiding installation errors caused by belt slackness or twisting, thereby ensuring the normal operation of the belt scale.
