Detailed Description

The technical solution is described in detail with reference to specific embodiments below.

As shown in fig. 1, the present invention is a screw lifting rivet pressing mechanism for a bookbinding machine, and the present embodiment is a basic implementation structure of the present invention, and two sets of screw lifting mechanisms are adopted to respectively complete a punching function and a rivet pressing function. The base is provided with a driving motor 1 and a punching rotating wheel 11, and the output shaft of the driving motor is a worm 1-1 which is connected with the punching rotating wheel 11 through a worm gear. The perforating rotary wheel 11 is rotatably arranged on the base 3 and can not lift and move relative to the base. The inner hole of the punching runner is provided with a thread which is in threaded connection with a punching screw. The top end of the punching screw 10 is connected with a punching rotation limiting block 6 which limits the punching screw to be incapable of rotating. The punching rotating wheel is in toothed connection with the pressure riveting rotating wheel 4, the pressure riveting rotating wheel is rotatably arranged on the base, and the pressure riveting rotating wheel cannot lift and move relative to the base. The inner hole of the pressure riveting rotating wheel is provided with threads which are in threaded connection with the pressure riveting screw rod 5. The top end of the pressure riveting screw is fixedly connected with a pressure riveting rotation limiting block which limits the screw to be incapable of rotating. The spiral directions of the punching screw and the pressure riveting screw are the same, the rotating directions are opposite, and the lifting directions of the punching mechanism and the pressure riveting mechanism are opposite. The drilling rotation limiting block is fixed at one end or sleeved on the drilling screw rod and the pressure riveting screw rod, and the other end of the drilling rotation limiting block is connected with the rack, the base or other parts to limit the drilling screw rod and the pressure riveting screw rod to be incapable of rotating and only capable of lifting relative to the base. The punching rotating wheel and the pressure riveting rotating wheel are in tooth joint or are in belt transmission, the spiral directions of the punching screw and the pressure riveting screw are in the same direction during tooth joint, and the spiral directions of the punching screw and the pressure riveting screw are opposite during belt transmission.

In the operation process, the driving motor rotates to push the punching rotating wheel connected with the motor output worm to rotate, the punching rotating wheel pushes the pressure riveting rotating wheel to rotate, and the pressure riveting screw is connected with the rotating wheel in a threaded mode. Because the punching screw rod and the riveting screw rod are limited from rotating, relative lifting movement is generated.
