The application discloses a full-automatic hydraulic four-side rotary plate splicing machine, and belongs to plate processing equipment. The machine comprises a rack, a four-side rotary workbench driven by a turbine speed reducer and supported by bearings, an electric switch door lock actuator and a door lifting oil cylinder arranged between the workbench and an intermediate support, a pressing module and an extrusion module arranged above the workbench, the extrusion module comprising a side pressing oil cylinder and a side pressing plate, a rolling slide group of the workbench driven by a first air cylinder, a roller sleeve anti-skid sleeve for realizing plate transfer, and a discharging module arranged on the inner side of the rack and driven by a second air cylinder, a screw rod and a screw rod motor to drive multiple sets of elastic telescopic blocks to elastically extend and retract to discharge, wherein the telescopic blocks comprise a shell, a spring and a telescopic plate, and a sliding block and a guide slide rail are in sliding cooperation to limit deviation and ensure accurate and smooth discharging action. The machine can realize full processes of automatic plate feeding, four-side rotary positioning, hydraulic extrusion plate splicing and automatic discharging, has high automation degree and plate splicing precision, is stable in operation, and can improve processing efficiency and product quality.

The swing assembly comprises a motor and a first crank in transmission connection with the motor, a connecting shaft is arranged at the other end of the first crank, the connecting shaft and the first crank are arranged in a non-coaxial mode, one end of a push rod is rotatably arranged on the connecting shaft in a sleeving mode, the other end of the push rod is used for being hinged to a swing frame, and the swing assembly further comprises an induction assembly installed on a base. After a stop instruction is received, the motor drives the connecting shaft to rotate to a stop position, so that the induction assembly is triggered, the motor is shut down, and when the connecting shaft is located at the stop position, the push rod and the first crank are collinear, that is, the torque on the first crank in the acting force direction of the push rod is zero. Therefore, when the seat part is in a shutdown state, the impact load generated by sitting of a user cannot act on the motor, so that the service life of the motor is prolonged.

The invention discloses a kicking type sudden stop rear mixing roller reversing device of an open mill. The kicking type sudden stop rear mixing roller reversing device comprises a moving module, a speed reducing module and a reverse rotating module. The moving module comprises a frame body arranged on the machine body and a flange located on the inner side of the frame body, and the flange can be controlled to carry the second gear and the second roller body to be away from the first roller body. The reverse rotation module is used for driving the first roller body and the second roller body to rotate in the second direction. The invention relates to the technical field of open mill equipment, roller body separation, inertia deceleration and automatic reverse rotation are integrated, after a machine body suddenly stops, a moving module firstly separates two roller bodies, and continuous extrusion is avoided; and the speed reduction module automatically brakes the driven roller to prevent the foreign matters from being continuously drawn in. Manual intervention is not needed in the whole process, and the risk of secondary injury is avoided. The two roller bodies are separated firstly and then reversed, the impact load is relieved in the separation process, and equipment parts are effectively protected.
