Abstract

A punching and binding machine comprises a punching mechanism and a binding mechanism located in the front and rear part of a body. The punching mechanism includes a plurality of punchers which can be driven to travel transversely to punch paper placed on a paper holder. Beneath the paper holder there is a support element incorporated with an eccentric rod for adjustment of distance between position to be punched and edge of paper. The binding mechanism makes use of a sliding board and a shifter holder to open clipping element of a binding ring placed on a fixing plate on its upper casing by a shifter for binding of the papers. It has a sliding board sliding in the sliding slots on the left and right body elements, and a stopping element to adjust sliding interval in order to control the size of clipping element opening opened by the shifter for binding with binding ring of different diameter.

A punching and binding machine to punch papers by transverse feeding of punchers and then bind such papers with a binding ring, comprising

a body composed of a left body element and a right body element, having a knob, a pull lever and a control lever at their appropriate positions on a side of the right body element, a stop plate extended upwards from the back of the body, a movable adjusting board mounting on the stop plate, a seat portion formed on the back of the adjusting board and movably fixed on the stop plate by means of a fixing bolt, and a plurality of punching marks located beneath the stop plate for aligning of papers;
a punching mechanism located in the rear part of the body, incorporated with a linking gear on the body and engaging with a lower gear below a control cam in connection with an upper gear for engaging with a rack beneath a feeder block with a plurality of vertical puncher control levers to push a plurality of punchers arranged in parallel, each positioned in a slot below a fixing plate, having a bent portion at a side of its rear end and an arched cutter at its front end, and having a paper holder in front of the punchers incorporated with a support element having an eccentric rod in it so that by rotation of the knob, the distance between the position to be punched and the edge of papers can be controlled, and a upper cover to cover the punching mechanism;
a binding mechanism having a sliding slot and two fixing holes on the left body element, and a sliding slot and two fixing holes on the right body element for installation of a sliding board, a support rod and a transmission shaft, in which the sliding board has a positioning element at one end and another positioning element at another end, each of the positioning elements has an oblique slot at the front end for holding of a tab extended from an end of the shifter holder, and to position the positioning elements in the sliding slots on the left and right body elements, a rack is located at the lower end of each positioning element to engage with a sector gear at each end of the transmission shaft which is extended to outside of the right body element to connect a control lever, the shifter holder has a plurality of L-like shifters, a passing slot and positioning slot are designed below the sliding slot of the left body element for fixing of a stopper element by means of a round head bolt in order to permit the stopper element to slide forwards or backwards in the passing slot and the sliding slot, and an upper casing is used to cover the binding mechanism with a plurality of long slots at appropriate positions for passing of the shifters, and a fixing plate extended vertically upwards from the back end of each long slot for holding of a binding ring.
