The invention discloses hot rolled plate shearing equipment for rolled plates in a steel mill, and relates to the technical field of hot rolled plate shearing, the hot rolled plate shearing equipment comprises a lathe, a hydraulic cylinder is mounted in the middle of the top end of the lathe, a mounting seat is mounted at the end of an output shaft of the hydraulic cylinder, a cutter is mounted in the middle of the bottom end of the mounting seat, and a stress balance mechanism is mounted on the outer side of the cutter; a driving lead screw is rotationally mounted at the corner of one side of the side end face of the mounting seat, and a transverse moving seat is mounted on the outer side of the driving lead screw through threads. The cutter abrasion degree can be detected, the controllability of the cutter abrasion degree is effectively improved, the cutter abrasion state can be timely and effectively mastered, the stability and effectiveness of shearing work are fully guaranteed, and the cutting efficiency is improved. The shearing efficiency and the shearing quality are synchronously improved, the curling and bending phenomena of the cutter can be effectively found in time, the shearing stress balance in the cutting process is fully guaranteed, the cutting loss rate of a hot rolled plate is reduced, and the shearing quality is guaranteed while the performance of the cutter is fully exerted.

This utility model provides a paper feeder for high-strength seamless resin tube production, relating to the field of feeding equipment technology. It includes a main frame assembly; two sets of sliding components are slidably installed on the main frame assembly, with a moving component sliding at the outer end of each sliding component, and a lifting component positioned at the lower outer end of the moving component. The sliding components are directly slidably installed on the transmission rods and other components of the main frame assembly, and the moving component can be slidably installed on the sliding components. The lifting component on the moving component can achieve lifting and lowering. A rotating component installed on the moving component can pass through a bearing shaft, allowing the bearing shaft to be mounted on the rotating component to support the paper feed roller, thus achieving the feeding function of the paper feed roller. This solves the problem of needing specific equipment for lifting, the potential for unnecessary safety hazards when using ordinary hoisting equipment, and the problem of paper roll rotation and conveying jams when using the equipment's own lifting device.

The application discloses a database bidirectional data synchronization method, an electronic device and a computer program product, and belongs to the technical field of databases. The method comprises the following steps: generating target hash data based on change data of a first database, and storing the target hash data into a target sending thread of the first database; the target sending thread is any one of a plurality of sending threads in the first database; the target sending thread sends the target hash data to a target receiving thread of a second database; the target receiving thread is a receiving thread corresponding to the target sending thread in a plurality of receiving threads in the second database; the target receiving thread traverses each sending thread in the second database based on the target hash data, checks whether there is a same hash value as the target hash data, and obtains a check result; and performing data synchronization on the second database based on the change data of the first database according to the check result.
