The invention relates to a binding
machine for office supply bills and documents, of which the structure is a
moving frame consisting of an upper moving plate, a lower moving plate, and a first guide rod, a second guide rod and a third guide rod which are arranged between the upper moving plate and the lower moving plate; the
moving frame is arranged in a rack and is provided with an upper press riveting
scalding head module, a
punching module, a
conductive rubber module and a lower press riveting
scalding head module; the rack is provided with a working panel, a
punching press riveting upper and lower moving module, a binding
pipe in-place detecting module, a binding
pipe conveying and pressing head releasing module and a pressing head component
self locking mechanism. The binding
machine is good in intelligentization, artificial participation is less, residual materials are convenient to take, the residual materials in a feeding working module can be automatically discharged, each working module of the whole
machine is reasonably stressed in the whole
binding process, and the pressing head module is not subjected to a
binding force, such that the damage rate of the pressing head module
self locking mechanism is greatly reduced, and the binding machine more meets the office requirements.
