Abstract

The utility model belongs to a cutting tool which is especially suitable for cutting paper sheets. A sector wheel is fixed on a cutting rotary element, and a cutter is driven by the cutting rotary element to move up and down along a guiding rail; simultaneously, the sector wheel drives a pressing plate through a tension element to move up and down along a guiding key under the action of an elastic element so as to realize the linking operation of pressing and cutting paper. A gear wheel which is rotatablely assembled on the lateral face of a pushing element moves along a rack bar fixed on the lateral face of a work bench so as to drive the pushing element to advance or retreat along a scale. The utility model can also exactly cut the flaky plastic, lumber, hide, insulative material, etc. The utility model has the advantages of simple structure, and labor-saving, safe, fast and convenient operation.

Description

The interlock guillotine

The utility model relates to a kind of guillotine, and it is particularly suitable for the processing of cutting of paper.

Commercially available cutting

The paper machine, all adopt the screw mandrel transmission or manually come platen and push away paper, operation easily, platen is also unbalanced, paperboard and inaccurate weak point when pushing away paper, disclosed paper cutter among the novel patent ZL00251296.3 of China is characterized in that realizing behind the platen cut paper again by cam that there be the structure weak point also inconvenient than complex operations in it.

The utility model purpose is to avoid above-mentioned the deficiencies in the prior art, and a kind of quick, laborsaving, safe ready cut paper guillotine accurately again is provided.

The purpose of this utility model is achieved in that

In Cutter apron, cut the commentaries on classics part and be fixed with sectional wheel, an end of flexible element has been fixed on the sectional wheel right side, flexible element by sectional wheel and pulley after, the other end is fixed on the pressing plate, is provided with elastic component between pressing plate and the Cutter apron, and pressing plate just moves up and down along feather key when cutting the rotation of commentaries on classics part, be assemblied in the cutting knife that cuts on the commentaries on classics part simultaneously and also move up and down, realized the combined operation of platen cut paper by guide rail.Impeller one side that is installed on the workbench is equipped with gear, and gear matches with the tooth bar that is fixed on the workbench ipsilateral, and impeller is just advanced and retreat than equilibrium before and after tooth bar and scale accurately when transmitting gear.

Further specify as follows below in conjunction with accompanying drawing:

Fig. 1 is the front view after embodiment removes the Cutter apron protecgulum;

Fig. 2 is that Fig. 1 removes cutting knife, cuts the front view that changes part and cut depression bar;

Fig. 3 is the partial sectional view of Cutter apron at Fig. 2 position A-A:

Fig. 4 is the vertical view of embodiment;

Fig. 5 is the partial sectional view of B-B among Fig. 4.

In diagram, workbench 18 upper forepart vertical fixing have Cutter apron 5, be fixed with macro-axis 15 on the Cutter apron 5, little axle 9, guide rail 4, guide 8, fixed pulley 10 sliding fitting on the little axle 9, the back side is fixed with cutting of sectional wheel 13 changes part 12 upper ends and is equipped with and cuts depression bar 6, cutting commentaries on classics part 12 middle parts fits on the macro-axis 15 with sectional wheel 13 concentric hole cunnings, cutting knife 17 upper right quarters are fixed with axis 16 sliding fitting over and cut in commentaries on classics part 12 bottom holes, be equipped with movable pulley 2 on the pulley spindle 3 that cutting knife 17 upper left quarters are fixed, movable pulley 2 is sliding again to be fitted between two guide rails 4, one end of flexible element 11 is fixed on fan-shaped right flank with hold-down screw 14, flexible element 11 is by the outer round recessed of sectional wheel 13, after passing the outer round recessed of movable pulley 10 again, its other end is fastened on the position, middle and upper part of pressing plate 19, pretension is equipped with several elastic components 7 between pressing plate 19 tops and Cutter apron 5 inner top surfaces, and the some groove cunnings in pressing plate 19 back fit in corresponding some the vertical feather keys 8.Drive to cut and change part 12 and be pressed in when rotating on the macro-axis 15 when cutting depression bar 6, just drive axis 16 pulling cutting knife doors and move up and down between two guide rails 4, flexible element 11 also spurs pressing plate 19 and moves up and down along feather key simultaneously.So just be laborsaving, realize the combined operation of disposable platen cut paper again quickly to the cutting of sheet cut material 20.Impeller 24 is equipped with in the back on workbench 18, scale 23 sliding fitting in the groove of impeller 24 lower left quarters, and scale 23 is fixed on the left side, workbench 18 back, pinion stand 26 is fixed on the left surface of impeller 24, gear 22 is fixed on the middle part of gear shaft l and sliding simultaneously fitting in the pinion stand 26, handwheel 27 is fixed on gear shaft 1 left end, be fixed with the tooth bar 21 that matches with gear 22 in left side, workbench 18 back, also just drive impeller 24 during with regard to driven gear 22 27 the time and slide when changing hands wheel along pre-and-post equalization in tooth bar 21 and the scale 23, transverse plane is provided with downward some boss C before the impeller 24, boss C stretches in some grooves on corresponding workbench 18, long paper phenomenon when so just having avoided pushing away paper fully, thus realized that scale accurately pushes away the paper operation again easily.Cutting depression bar 6 hand-holding parts should be suitably crooked.On sectional wheel 13 relative positions of the right, Cutter apron 5 back, be equipped with resilient pin 28, when cutting the edge of a knife when being up to the extreme higher position, the bullet pin is with regard in the corresponding hole on the automatic insertion sectional wheel, cutting knife 17 is not fallen, play the security insurance effect, only need resilient pin pulled out and to begin processing when putting paper when work well.

The utility model optimum implementation is:

Elastic component is four on a tapered spring, spring should have certain precompression when installing, flexible element is a high-test chain, feather key adopts two, the boss of below, the same plane of impeller front end adopts four, the corresponding workbench upper groove of boss also is four, cuts the depression bar hand-holding part and is bowed downward to 160 °.
