Abstract: The present disclosure belongs to the technical field of mechanical spraying, and a color change block with detection feedback as well as spraying equipment are provided. The color change block with detection feedback comprises a cleaning agent valve module, a color change micro valve module, a mixing pipe module and a turbidity detection module which are connected in sequence. A complete collinear common channel is formed among these modules, and the wall surface of the common channel is a complete plane. The turbidity detection module is further connected to the control module and used for monitoring the turbidity of a medium flowing through the common channel in real time so as to determine whether the medium in the common channel meets a cleaning requirement or not and feed a determination result back to the control module, and then the control module switches other media to form a closed-loop control.

Abstract: A gripper mechanism is provided, which relates to the technical field of grippers. The gripper mechanism includes a motor, a cylinder barrel, a piston and a guide assembly. The piston reciprocates in the cylinder barrel under the action of the motor and the guide assembly. The piston includes a piston body and a piston rod located in the piston body. Both ends of the cylinder barrel are respectively provided with cylinder heads for limiting the maximum distance and the minimum distance between the piston body and a part to be gripped. The piston rod includes a driving shaft, a cross slider coupling and a gripping head which are connected in turn. The power output by the motor is transmitted to the gripping head through the driving shaft and the cross slider coupling in turn.
