Modularized punching and bookbinding machine and piercing die group for punching and bookbinding machine

Abstract

The invention relates to a modularized perforating book binding machine and a perforating pattern assembly used for the perforating book binding machine. The perforating book binding machine comprises a driving device, at least a perforating pattern assembly and a main body. The perforating pattern assembly comprises an upper die fixed seat, a lower die fixed seat, two joining components and two elastic components. A plurality of piercing heads is arranged in the upper die fixed seat, is contacted with the upper die fixed seat, and then the driving device drives the upper die fixed seat. The lower die fixed seat is provided with at least a through hole for the piercing head passing through. The joining component is respectively connected at the both ends of the upper die fixed seat and the lower die fixed seat. The elastic components are respectively supported and leaned at the both ends of the upper die fixed seat and the lower die fixed seat. The main body is provided with two projecting blocks which are used for supporting the both ends of the lower die fixed seat, thereby when being disassembled, the driving device only is required to be disassembled, the whole pattern assembly of the perforating pattern assembly can be taken out. The disassembly steps are simpler than the traditional perforating book binding machine, and the required take time also can be reduced.

Description

technical field [0001] The invention relates to a punching and binding machine for loose-leaf paper and a punching module used for the punching and binding machine, in particular to a punching mechanism of a modular loose-leaf paper punching and binding machine and a punching module for punching and binding the machine. Punching module for hole binding machines. Background technique [0002] Present conventional loose-leaf paper punching and binding machines usually include a punching mechanism and a binding mechanism. As far as the punching mechanism is concerned, it includes an input rod, a transmission shaft, a plurality of gears, a plurality of racks, a punch plate, a punch guiding device and a plurality of springs. The input rod is used for receiving an external force. The transmission shaft is connected to the input rod, and is used for driving the gear, the rack and the punch plate by the transmission of the external force. The rack is fixed on the punch plate. Th...

Problems solved by technology

[0003] The disadvantage of the punching mechanism of the conventional loose-leaf paper punching and binding machine is that the input rod, the transmission shaft, the gear, the rack, the punch plate, the punch guide and The springs and other components are packed in bulk in the punching and binding machine, so if it is necessary to repair or replace the punch plate for disassembly and assembly, all the components must be disassembled and assembled one by one, which is very time-consuming
