Variable frequency paper shredder

Abstract

The invention discloses a variable frequency paper shredder. The variable frequency paper shredder comprises a conveying belt; a pulverizer device is arranged at the bottom of the conveying belt; a variable frequency motor is arranged at the bottom of the conveying belt; a hot air blower is arranged in the pulverizer; an inductor is arranged on the inner wall of a paper outlet; a hydraulic expansion device is arranged on one side of the inductor; a moving rod is arranged at one end of the telescopic expansion device; a screening plate is arranged at the bottom of the moving rod; a rotating rod is arranged at the bottom of the screening plate; a fixing button is arranged on one side of the rotating rod; the rotating rod is connected with the screening plate through the fixing button; a control panel is arranged on one side of the pulverizer device; the variable frequency motor can control the paper scrap cutting frequency of the paper shredder; the hot air blower can clean paper scraps which are adsorbed on a cutting blade and the inner wall of the paper shredder; lager paper scraps which are not pulverized completely can be pulverized secondarily; the paper scrap falling frequency can be controlled by the size of the opening of the rotating plate; the overall device is simple in structure, and the paper scrap recovery rate is high.

Description

technical field [0001] The invention relates to a paper shredder, in particular to a frequency conversion paper shredder. Background technique [0002] A paper shredder is a machine used to shred paper, but the shredders currently on the market are all ordinary single-slice shredding structures, the shredding is not thorough, the shredded paper is uneven, the shredding effect is poor, and it cannot be automatically Feeding requires manual feeding, which is slow and tiring, resulting in low crushing efficiency. Moreover, after shredding, the inner wall of the shredder in the prior art will absorb a lot of shredded paper, which cannot be used , lead to waste of raw materials, and also reduce efficiency, and the shredders on the market cannot adjust the shredding speed of the shredder, and the frequency cannot be well controlled and changed, which will waste a lot of time, material resources and resources. financial resources. Contents of the invention [0003] The technica...
