Shredder structure and working principle: shredder has two main parts "paper cutter" and "electric motor", through the belt and gear to make it closely connected together, the motor drives the belt, gear, transfer energy to the paper cutter, and the paper cutter through the rotation, with sharp metal Angle to cut the paper.
Some paper shredders on the market can choose two or more paper shredding methods. Different paper shredding method is suitable for different occasions, if it is a general office, choose segment, granular, filamentous, strip is OK. But if it is to use some of the confidential requirements of the higher occasion must use foam. At present, THE paper shredding method composed of four knives is the most advanced working method. The paper particles of the shredding paper are neat and neat, which can achieve the effect of confidentiality.
Shredder cutting principle through the blade or tool dislocation placement, in the power source will tear the paper. If the tool or blade is set with a tip, the shredding effect is segmental or granular. If the tool or blade is set without a tip, the shredding effect is strip.
Each type of motor has a limited amount of power, just like the car's rated load, marked out a shredder designer flown several indicators, so as to guarantee the machine not overworked, if the user does not press a limited amount of index operation, can appear in addition to the above mentioned: the more anxious, more want it more than a few sheets of paper, machine is overloaded work, the more serious error... In addition to the phenomenon, serious will burn the motor. Therefore, the index of limiting the number of pieces of paper is to form a code of conduct from the user's mind to actively protect the service life of the motor; In addition, good brand shredder and some safety protection, overload protection and other facilities, such as: in the placement of unsafe, the machine will be forced to stop working; Machines are shut down during periods of chronic overwork; In addition, the humidity and dust in the working environment have a great impact on the electrical components of the shredder.
Secondly, the cutting tool of the shredder is the core part, but also the most technical part.
First talk about the choice of cutting tool steel: a good tool is usually choose foreign high strength tungsten steel to manufacture, this is a good choice, but also a costly choice, some cheap machine because of the cost, can only use cheap hardness slightly worse steel, the consequence is a high failure rate and short service life;
Talk about processing technology and processing cost again: Because of the high strength tungsten steel is relatively hard, processing difficulty and the cost will be much worse than the hardness of steel high, the cost increase again, high strength tungsten steel made sharp degree and tool life can bring benefits far beyond cost reduction, machine failure rate is high reputation declined, choose cheap materials do not pay;
Then talk about the level of tool assembly: because the processing of high strength tungsten steel process is fine, high accuracy, the difficulty of assembly is high, so the manufacturers with international certification of the production process will be guaranteed;
Of course, it should also be mentioned here that no matter how good the knife is, it is necessary to avoid breaking nails, sand and other hard objects, just like human teeth, eating the occasional sand is fine, if you bite the sand every day, no matter how good the teeth will be broken. In fact, choose a good tool, you have reduced the chance of failure in half.
