Structure and working principle of the paper shredder
The shredder has two main components, "paper cutters" and "motors", which are tightly connected by belt and gears. The motor drives the belt and gears to transfer energy to the paper cutter, which rotates out paper with sharp metal angles.
Some mills on the market can choose two or more modes. Different pieces of paper are suitable for different occasions. If it is a general office occasion, you can choose segmented, granular, silk, strip. But if used in some high confidentiality situations, it must be foamy. The paper scraps composed of four knives is the most advanced working mode, the broken paper is neat and uniform, can achieve the effect of confidentiality.
The shredder cutting principle is to tear the paper through the dislocation of the blade or tool under the power source. If the cutter or blade has a knife tip, the paper chip effect is segmented or granular, and it is striped if the cutter or blade has no knife tip.
The Development of Automatic Paper Shredders
The first generation was mostly low noise belt drives. But after a long time of work, the belt deformation and pull up, or even break, the teeth on the belt surface are easy to wear, causing the machine to skid.
In the second generation of plastic gear transmission, it is difficult to accurately grasp the injection molding and contraction process of plastic gear, resulting in low accuracy and high noise during high-speed operation; due to the poor brittleness and toughness of plastic parts.
The third generation of metal sprocket: silent operation, low energy consumption, high efficiency cutting, cutting system parts of the perfect coordination, to achieve convincing functions.
The transmission mechanism of the fourth generation of paper shredder is a metal gear drive, which overcomes the above defects. However, due to the installation accuracy of the metal mechanism, the lubrication condition of the gear engagement position, the lubrication effect of long-term operation and other technology and maintenance are not controllable.
The fifth generation of diamond close fitting movement using alloy steel material, metal tool quenching treatment, complete CNC machine processing process, technically ensure the installation accuracy of transmission parts, wear to the minimum, ensure the stability of product quality stability, reduce the noise. Quality assurance; super all steel all metal gear, special steel hob, high quality high strength motor.
The sixth generation of high-tech multimedia series grinder, high technical content; a large number of CD, floppy disk, tape, video, etc.; Button panel with protective film to ensure forward, backward, stop, stop and other functions when full paper.
Now the seventh generation is focused on the quality of life, products in the environmental protection function and performance safety have higher requirements. Therefore, the storage box partition, motor overheating protection, overload automatic shutdown, storage box automatic power off and other functions are more and more used.
Based on meeting the multi-function and high-performance requirements, the eighth-generation paper shredder has made great progress in improving the paper shredding ability, safety level and service life.
