Abstract
A punching and binding machine, particularly a machine to punch and bind papers at high speed, comprises including a punching unit and a binding unit adapted for independent operation. The punching unit has an upper clamp element and a lower clamp element for use in punching operations and the binding unit incorporates an adjustment mechanism for selecting the use of either an iron binding ring or a plastic binding ring of appropriate diameter for binding of papers of different thicknesses.
Claims6
A punching and binding machine comprising:
- a base having a back section, a stepped seat with a plurality of ring number indications and steps formed on a right front portion thereof, a slot formed at a left side thereof, a positioner movably fixed to a screw rod, a plurality of punching marks and a paper dust collecting drawer;
- an operation mechanism removably fixed to the back section of said base, said operation mechanism including a right fixing block and a left fixing block, each of said fixing blocks comprising a fixing board and an outer casing;
- a punching unit including a horizontal seat provided with a plurality of passing holes each of which is adapted to receive a puncher control rod inserted horizontally therein, a positioning spring plate located beneath each puncher control rod, a puncher installed below a front end of each puncher control rod for controlling the number of punchers in operation, each of said punchers being arranged vertically on a lower block beneath the horizontal seat and being connected to the horizontal seat by means of a pin so that each puncher can be displaced toward the lower block in response to movement of the horizontal seat, said horizontal seat having a bent lower front end defining a movable upper clamp element, said lower block having a bent front side defining a fixed lower clamp element which is adapted to be engaged by the lower front end of the movable upper clamp element upon upward and downward movement of the horizontal seat, said horizontal seat being mounted within a guide slot formed in each of said fixing boards by a respective side projecting plate and by a feeding lever movably mounted outside the left fixing block which is connected to a gear at each side of a feeding rod, said feeding rod being engaged with a rack at each end of the horizontal seat in order to cause displacement of the horizontal seat downward by moving said feeding lever, and consequently shifting the puncher control rods downward to cause the respective punchers to punch papers placed below the lower block, said punchers are then returned to their original positions under the force of a spring positioned at each side of the horizontal seat;
- and
- a binding unit including a plurality of shifting rods carried by a fixing seat, a lower board, a pushing board upon which said fixing seat is mounted and an upper board, said upper and lower boards being fixed to the left and right fixing blocks of the operation mechanism respectively, said binding unit being driven by eccentric cams each of which is carried by the operation mechanism and is formed with a guide slot for receiving a respective end of a guide rod secured to said pushing board such that rotation of said cams causes shifting of said pushing board and displacement of said fixing seat and shifting rods.
