through actual investigation and use experience, the paper shredder breaks paper every time from single paper to multiple paper every time in early stage, and then the paper shredder does not need staple or clip disassembly, and the paper shredder finds that the paper shredding amount of the paper shredder is greatly related to the torsion and duration time of a paper shredding knife during paper shredding, namely the larger the working current of a motor driving the paper shredding knife is, the more paper shredding amount of one time is indicated to belong to positive correlation, so that the corresponding paper shredding amount can be calculated only by recording the current and duration time during paper shredding every time, and the paper shredding barrel is accumulated to be full, and the user is prompted to empty the paper shredding barrel in a mode of suspending operation, displaying or indicating lamps or voices in an LCD (liquid crystal display) and the like, so that the operation of the user is greatly facilitated.
The theoretical workload of the motor when paper is full is equal to the sum of products of the working current of one operation and the working time length of one operation of the paper shredder, namely:
M＝∑(I n T n )
m is the theoretical workload of the motor when paper is full; i n Working current for one-time operation of the paper shredder; t (T) n The working time of one operation is long.
The sampling may be converted to electrical power;
the electric power for the motor work when paper is full is equal to the sum of the products of the working power of one operation and the working time length of one operation of the paper shredder, namely:
W＝PT n
P＝220I n
electric power is used for motor work when the W paper is full; p kneader one-time operation working power; the parameter 220 is the rated voltage 220V.
Ageing coefficient of paper shredder working part N%: the coefficient of variation in the working efficiency with time due to the accumulation of the working time length and the working portion mechanism performance degradation is N%.
Other abrupt current disturbance variable R: when encountering staples or clips and compact discs or cards, abrupt changes in current are caused, and judgment is made according to the abrupt current or the power change duration, so that the difference between the count increased and the actual generated fragments is obtained.
Thus, it follows that:
m real = Σ (I n T n )N％-R n
M real is the actual workload of the motor when the paper is full
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
