Description

Cutter for thin sheet materials
The utility model belongs to cutting means, is mainly used in the Sealing cutting machine for packing tool, and cutting object is film, paper and fibrous flexible sheet shape composite.
Existing cutting means mainly contains following several: one, common scissor, though structure simply, cuts fabric width little (generally being no more than 80 millimeters), subtended angle is big, dangerous, thereby the scope of application is very limited.They are two years old, following cutter is fixed, the horizontal formula that moves up and down of upper slitter, though this kind form fabric width improves greatly, but the apparatus structure complexity, machining accuracy is higher, must adjust the gap of cutter up and down with a plurality of screws during use, there have slightly as adjustment to be improper, will cause the cutter concentrated wear serious or cut not wellly, and refacing of cutter must be carried out very inconvenience on grinding machine.Its three, following cutter fixes, when upper slitter moves up and down with around the axis rotary type that is parallel to fabric width, the advantage of this kind form is that fabric width is big, Installation and Debugging are simple; Because cutter tight-lipped subsides of two-edged under the effect of spring force up and down, need not use the screw adjusting play, but weak point is that following edge is easily by rounding, cause the lost of life, hinge point is many, easily vibrations have limited the raising that cuts frequency, shortcomings such as complex structure, the machining accuracy that exists above-mentioned second kind of form in addition equally is higher, the inconvenience of refacing.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved cutting means is provided, and it is not only simple in structure, installation, adjustment, easy to maintenance, and cut brisk, reliable operation.
The purpose of this utility model is achieved in that the deficiency that exists at prior art, the mounting means and the motion control mechanism of upper slitter is improved, thereby simplified structure, improve performance.The utility model is made up of upper slitter, upper slitter bearing, following cutter, supporter and upper slitter motion control mechanism.The upper slitter motion control mechanism comprises control button, motor, decelerator, eccentric wheel, driven pulley, pivot pin, pull bar, sliding sleeve, spring, dog screw and push type broach spring.The mounting means of upper slitter is a cantilevered.Each parts is assembled in the following manner: supporter is a mesa structure, and following cutter and upper slitter bearing are installed on its table top; The upper slitter bearing is the slot type structure, and dog screw is installed in respectively on its two relative cell walls with push type broach spring coaxial line ground; One end of upper slitter is anchored on the upper end of pull bar, and its other end is arranged in upper slitter bearing groove, by dog screw and the movable clamping of push type broach spring; Sliding sleeve is two, be installed on the supporter, and its axis is vertical with the table top of supporter their coaxial lines, and pull bar inserts sliding sleeve and forms hinges; Pivot pin is fastened on the lower end of pull bar, and its axis normal is in the pull bar axis, and an end of pivot pin is installed driven pulley, and the other end connects spring; Eccentric wheel is a driving wheel, and it cooperates installation with driven pulley, the output termination eccentric wheel of decelerator, its input termination motor.Because said structure, behind starter motor, pull bar drives upper slitter and makes compound motion under the effect of eccentric wheel and spring, and make up and down blade forms portable some contact in the process of cutting.
According to theoretical analysis and calculation and test, upper slitter of the present utility model is that the upper slitter blade has the 0.05-0.2 mm clearance with the starting point place that following cutter blade is positioned at drag link end with the best position of following cutter, and the upper slitter blade cuts the preceding angle of cut that is 0.5 °~3 ° in the space of beginning with following cutter blade; The rigidity of push type broach spring is 0.3~0.6kg/mm; The angle of putting the first edge on a knife or a pair of scissors of upper slitter is 30 °~60 °, and the angle of putting the first edge on a knife or a pair of scissors of following cutter is 3 °~8 °.
The utlity model has following advantage:
1, simple in structure, with existing congenerous, compare with the device of fabric width, its processing parts only is 50%, and the difficulty of processing of part and precision also greatly reduce;
2, the design feature of the mounting means of upper and lower cutter and upper slitter motion control mechanism has not only been simplified installation adjustment operation and workload (as long as the parallel cutter down that moves, just can make upper slitter and following cutter remain on best position), and help cutting the raising of frequency;
3, the choose reasonable of push type broach spring rate, it is constant that pressure at contact point is bordering on, and therefore wearing and tearing are comparatively even, but make after same period as long as transfer still operate as normal of big push type broach spring force slightly, improved service life widely;
4, the upper and lower cutter choose reasonable of angle of putting the first edge on a knife or a pair of scissors, make cut very brisk;
5, upper and lower cutter such as need are refaced, and needn't go up grinding machine, as long as with oilstone manual grinding a little, thereby have reduced maintenance time, have reduced maintenance cost;
6, cutting fabric width can reach more than 500 millimeters.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
