Description
Technical field
The utility model relates to a kind of shredder, specifically a kind of shredder with threshold device.
Background technology
Shredder in the market; in order to prevent that user's tatter amount excessive (surpass specified number too many) from causing resistance to cross ambassador's travelling gear and damaging and cause the machine can't operate as normal; this is fatal to shredder, mostly has following two kinds of methods of employing to carry out overload protection traditionally:
1, motor stall mode: utilize the acrotorque (or power) of restriction motor itself to protect.When promptly designing the intensity of gear is slightly larger than the maximum outputting torsion of motor, even the user is put paper amount over range, it also is motor stall (motor can't rotate), travelling gear does not still sustain and can damage, but shortcoming is not too to be suitable for use on the big machine of tatter amount, and the shredded paper speed of specified paper amount is slow partially, and efficient is low.
2, current sampling Protection Code: promptly press the used electric current of specified tatter amount as benchmark, putting the electric current of paper amount when exceeding specified tatter amount as the user will be greater than reference current, utilize the mode of electronics to allow machine stop by force then to reach the purpose of protection travelling gear, but shortcoming is: A, the current sampling Protection Code is too accurate, because movement and power train more complicated in the structure of shredder, the error rate of adding motor itself is than higher, whole movement is difficult to do consistently, therefore use the electric current sampling method, also just be difficult to guarantee the shredded paper number of shredder, when assembling as movement because burr or other factors make resistance bigger than normal, reference current is not done corresponding the raising and actual tatter amount will be occurred and do not reach specified tatter amount so, inefficiency (being defective work), production line is only done over again and is readjusted so, has also just improved the cost cost undoubtedly; B, in order to guarantee user's safety, in case the continuous constriction of paper inlet is behind the machine overload protection; take out remaining paper not a duck soup; that can only be to hope paper heave a sigh not have certain muscle power, for these deficiencies that exist, is that designer and user wish to be solved always.
