This invention relates to the field of material handling technology, and specifically discloses an adjustable material handling robot.

A sliding seat is slidably connected to the inner side of the base, and a movable frame is fixedly connected to the top of the sliding seat.

This controls the positive rotation of the drive wheel, driving the track to move upwards at a speed exactly the same as the downward speed of the workpiece, forming a relatively stationary state where the track moves upwards and the workpiece moves downwards, thus counteracting the downward displacement of the workpiece.

The boxes are accelerated through the friction drive of the speed pursuit rollers in the module until the boxes contact the front blocking plate and move synchronously with the module. Since multiple interval modules are fixed at equal intervals on the chain, the boxes conveyed by the interval modules are finally forced to be separated into completely equal intervals, which is more reliable than single adjustment mode.

It includes a permanent magnet synchronous motor and a traction sheave assembly. The permanent magnet synchronous motor has an output shaft fixed to its end, and the traction sheave assembly includes a traction sheave disc sleeved and fixed to the outer wall of the output shaft. This thin traction machine with a split-type inductive encoder uses the rotation of the traction sheave disc to cause a piston plate entering the upper semi-circular rotation area to slide against the inner side of the semi-circular force-applying plate, triggering the clamping column to extend the steel wire rope for physical clamping and synchronous transmission along the same line. When entering the lower semi-circular rotation, the piston plate and clamping column automatically reset to release the clamp. Thus, through the anti-slip mechanism of upper semi-circular rotation triggering – area clamping – lower semi-circular rotation release, physical clamping replaces simple friction transmission, completely eliminating the risk of slippage. Furthermore, clamping and release are automatically completed with the rotation of the traction sheave disc, requiring no additional control system, which conforms to the passive safety design concept of elevators.
