The invention relates to the technical field of computer hard disks, and discloses a hard disk crushing device capable of automatically adjusting the demagnetizing speed based on the crushing speed. The hard disk crushing device comprises a magnetic separator roller; a crushing device body and a demagnetizing device are arranged in the magnetic separator roller; an electromagnet is arranged in thedemagnetizing device; a connecting shaft is connected to the lower part of the electromagnet; a threaded rod is connected to the lower part of the connecting shaft; a sliding block is arranged on thethreaded rod; a movable demagnetizer is connected to the sliding block; the top end of the threaded rod is connected with a driving gear; and a rotating gear is arranged below crushing device body. According to the hard disk crushing device, the rotating gear is arranged below the crushing device body, and the rotating gear is connected together with the driving gear through a chain belt, and when the crushing device rotationally crushes and drives the rotating gear to rotate, the rotation of the driving gear is synchronously realized through the chain belt, so that the movement demagnetization of the movable demagnetizer indirectly connected with the driving gear is realized .
Description
technical field [0001] The invention relates to the technical field of computer hard disks, in particular to a hard disk shredding device that automatically adjusts the degaussing speed based on the shredding speed. Background technique [0002] The computer hard disk is the main storage device of the computer. Most of the software required for the normal operation of the computer is stored on the hard disk. It is composed of one or more aluminum or glass discs, and the discs are covered with ferromagnetic materials. . [0003] In today's highly developed informatization, for people whose hard disk contains sensitive information, if they directly discard or resell the hard disk, it is very easy to cause important data leakage. To completely delete, the hard disk needs to be completely shredded to ensure that the data in the hard disk can no longer be read, thus giving birth to the development of hard disk shredders. [0004] However, if you only use a hard disk shredder to...
