Abstract

A punching knife group of a bookbinding machine for a movable tool head relates to an improvement mechanism of the bookbinding machine in office equipment, and comprises a base, a lower knife die, a knife rest, a knife group limit bracket, a punching reset bracket, a knife blade limit spring plate, a reset spring, a knife blade reset guide rod, a cam, an edge distance limit plate and an regulating turn knob, wherein, the lower knife die and the knife rest are fixed on the base; the knife blade reset guide rod is fixed on the knife rest; a knife blade penetrate into the knife rest; the punching reset bracket penetrates the knife blade and the knife blade reset guide rod; the knife blade limit spring plate is buckled in a groove formed on the punching reset bracket; the cam is fixed on the base; and a hole edge distance limit plate is arranged on the knife rest. The utility model has the advantages of compact structure, simple manufacture and convenient use. According to different punching requirements, the punching knife group can be freely replaced, and meets the requirements of the different types like a rubber ring, an iron ring, a single coil and the like of bookbinding.

Description

The punching cutter group of movable carriage binder

Technical field:

The utility model relates to the improvement mechanism of the binder in the office equipment.

Technical background:

Existing text binder has multi-form needs such as cushion rubber, iron ring, unicoil, needs the punching cutter of difformity hole shape.And existing binder knife rest group mechanism and binder are fixed as one, and be so different texts bookbinding requires to need to change multi-form binder, not only time-consuming but also take cost.

Summary of the invention:

The utility model provides a kind of punching cutter group that cooperates the text binder of movable carriage group structure.

The utility model is achieved by the following technical solution: a kind of punching cutter group of movable carriage binder, its major technique feature are that it comprises base, following cutting die, knife rest, cutter group limiting bracket, punching reset cradle, blade positive stop spring plate, back-moving spring, blade reset guide bar, cam, back gauge limiting plate, regulates turn-knob; Following cutting die, knife rest are fixed on the base, and blade reset guide bar is fixed on the knife rest, and blade penetrates in the knife rest, and the punching reset cradle penetrates in blade and the blade reset guide bar; The blade positive stop spring plate buckles in the groove of punching reset cradle, and cam is fixed on the base, and knife rest is provided with hole back gauge limiting plate;

Described cutter group limiting bracket is fixed on the base, is provided with alignment pin and back-moving spring between base and cutter group limiting bracket.

The utility model compact conformation is made simple, easy to use.Can freely change according to different punching needs, adapt to multi-form bookbinding needs such as cushion rubber, iron ring, unicoil respectively.

Description of drawings:

Fig. 1, Fig. 2 are structural representation of the present utility model.

The specific embodiment:

As shown in Figure 1 and Figure 2, a kind of punching cutter group of movable carriage binder comprises base 1, following cutting die 2, knife rest 3, cutter group limiting bracket 4, punching reset cradle 5, blade positive stop spring plate 6, back-moving spring 10, blade reset guide bar 9, cam 12, back gauge limiting plate 13, regulates turn-knob 14.Following cutting die 2, knife rest 3 are fixed on the base, and blade reset guide bar is fixed on the knife rest, and blade 7 penetrates in the knife rest, and the punching reset cradle penetrates in blade and the blade reset guide bar; Moved down by the push type broach beam and to make blade finish punching, blade resets and is realized by the elastic force of back-moving spring 8.The blade positive stop spring plate buckles in the groove of punching reset cradle 5, can unload by hand, after unloading the bottom knife positive stop spring plate, can will not need the respective blade of punching to take out.Cam is fixed on the base, and knife rest is provided with the hole back gauge limiting plate 13 that can move forward and backward, and when rotating adjusting turn-knob 14, cam 12 rotates thereupon, utilizes the limit radius promotion back gauge limiting plate of cam to move forward and backward then, realizes the adjusting of text hole back gauge size.Cutter group limiting bracket 4 is fixed on the base, between base and cutter group limiting bracket, be provided with alignment pin 11 and back-moving spring 10, alignment pin can be up and down, by back-moving spring alignment pin resetted downwards, utilizes the corresponding locating hole realization cutter group of alignment pin and base and the location of frame.
