Abstract
The present invention relates to a new type protection device for shredders which comprises a paper number detecting device mounted at the paper inserting passage of the shredder, a warning device mounted on the shredder and a controlling device in line connection with the paper number detecting device and the warning device respectively, mounted in the shredder and in line connection with the driving component of the shredder driving the shredder blades, preferably the protection device further comprises an insert detecting device in line connection with the controlling device and mounted at the paper inserting passage, and at least one opaque shielding component mounted at the paper inserting passage and at the middle of which there is at least one slot along the length direction, the present invention controls the number of the paper to be shredded during the paper inserting stage, and shreds paper automatically only in a predetermined value range, to avoid abnormalities that result in failure of the machine such as jam and tooth breaking when the shredder is shredding many pieces of paper, so as to reduce maintenance times and cost, extend service life, and make application of shredders safer and more reliable, more convenient and simpler, then to achieve better protection of shredders.
