Description

Technical Field

[0001] The utility model relates to the technical field of plate turning machines, in particular to a plate turning machine for marble processing. Background Art

[0002] When processing marble into finished products, it needs to go through many processes. When completing these processes, the marble slab needs to be flipped over. The flipping machine is a device for flipping the marble slab. The flipping machine fixes the marble slab through a clamping mechanism, and then rotates it 180° through a rotating mechanism to achieve the flipping of the slab.

[0003] According to a marble processing flipping machine with publication number CN213059059U, it includes a frame, and a loading conveying system, a flipping mechanism, and a unloading conveying system arranged on the frame from left to right; the flipping mechanism includes a rotating shaft, a motor arranged outside the frame for driving the rotation of the rotating shaft, and a pair of clamping assemblies symmetrically arranged along the axis of the rotating shaft. When in use, the upper end surface of the lower clamping plate of the pair of clamping assemblies is flush with the conveying belt, and the marble slab moves to the clamping plate under the action of the conveying belt and the conveying mechanism on the clamping plate, and then the reduction motor of the conveying mechanism is turned off, and the cylinder is started to make the clamping plate of the clamping assembly stably clamp the marble slab, and then the motor is turned on, and the motor drives the rotating shaft to rotate so that the marble slab is turned over. After the flipping is completed, the clamping plate located at the bottom is flush with the conveying belt at one end of the unloading conveying system by adjusting the two cylinders of the clamping assembly, and then the reduction motor on the lower clamping plate is turned on, so that the marble slab after flipping is transferred to the unloading conveying system for the next processing operation.

[0004] The above patent mentioned that the marble slab moves to the clamping plate under the action of the conveyor belt and the transmission mechanism on the clamping plate, then the reduction motor of the transmission mechanism is turned off, the cylinder is started, the clamping plate of the clamping assembly stably clamps the marble slab, and then the motor is turned on, and the motor drives the shaft to rotate so that the marble slab is turned over. After the flipping is completed, the two cylinders of the clamping assembly are adjusted to make the clamping plate at the bottom flush with the conveyor belt at one end of the unloading conveying system. Since the transmission belt is located on both sides of the clamping plate, due to the limitation of the transmission belt, the clamping plate can only flip the marble slab that is smaller than the size of the clamping plate, which makes the application range of the flipping machine small and inconvenient to use.
