Description

Technical Field

[0001] The utility model belongs to the technical field of pulverizers, in particular to a hard disk destruction pulverizer. Background Art

[0002] A hard drive shredder is a device designed to physically destroy hard disk drives (HDDs) and solid-state drives (SSDs). Its primary purpose is to protect sensitive and confidential information by physically destroying the hard drive's storage media, rendering the data irrecoverable. A hard drive shredder typically physically destroys the hard drive's storage media, rendering the data irrecoverable. The resulting fragments are typically very small, preventing any form of data recovery.

[0003] For example, a Chinese utility model patent with announcement number CN219400489U discloses a hard disk destruction shredder. By setting a first filter and using the first filter in conjunction with the second filter, the dust generated by the shredder body when shredding the hard disk is prevented from flowing out through the feed port of the shredder body, which is convenient for use in occasions with higher environmental requirements in the future. By setting a support plate, when the staff sends the support plate into the interior of the feed frame, the support plate can block the feed frame, thereby preventing the dust inside the shredder body from flowing out through the feed frame after the installation frame is moved out of the interior of the feed frame. By setting a positioning block, the positioning block is movably mounted together with the positioning groove, thereby facilitating the positioning of the support plate.

[0004] However, when the device shreds the hard disk, it will form fragments of different sizes. These fragments need to be screened to facilitate further processing or recycling of the fragments of different sizes to ensure the effective use of resources and the treatment of electronic waste.

[0005] In summary, there is a need for a hard disk destruction shredder that can screen hard disk debris. Utility Model Content

[0030] The crushing assembly is used to crush hard disks. The crushing assembly includes two crushing rollers 6 and two symmetrically arranged conveying rollers 7. Guide plates are fixedly connected to both sides of the inner wall of the feed box 3 to ensure that the hard disk falls into the middle of the two crushing rollers 6. One end of the intermediate shaft of the two crushing rollers 6 is sleeved with two mutually meshing crushing gears 8. The other end of the intermediate shaft of the right crushing roller 6 is fixedly connected to the motor. A support block is installed at the bottom of the motor, and the back of the support block is fixedly connected to the front of the feed box 3 to ensure the normal operation of the motor. One end of the intermediate shaft of the two conveying rollers 7 is sleeved with two mutually meshing conveying gears 9. The other end of the intermediate shaft of the conveying roller 7 is rotatably connected to the front of the inner wall of the feed box 3. The outer side of the intermediate shaft of the right conveying roller 7 is connected to the outer side of the intermediate shaft of the right crushing roller 6 through a first synchronous belt drive. The surface of the conveying roller 7 is provided with an elastic rubber material, and the surface of the rubber material is provided with anti-slip grooves to facilitate the transportation of hard disks.

[0031] The screening component is used to collect the different specifications of the debris generated by the hard disk separately. The screening component includes two symmetrically arranged U-shaped frames 10 and two symmetrically arranged worms 11. The surface of the worm 11 is provided with two fixed blocks. One side of the fixed block is fixedly connected to one side of the box body 1 to ensure the normal operation of the worm 11. One side of the U-shaped frame 10 is fixedly connected to one side of the inner wall of the box body 1. The bottom of the inner wall of the U-shaped frame 10 is fixedly connected with small spring rods 12 at equal intervals. The bottom of the small spring rods 12 is fixedly connected with a pressure plate 13. The bottom of the pressure plate 13 is abutted with a return frame 14. The interior of the return frame 14 is fixedly installed with a screening box 15. The screening box 15 is a mesh box used to collect the larger particles after crushing. The hard disk slag is prepared by a double-door installation on the front of the box 1, and a handle is installed on the front of the double-door installation to facilitate the placement of the box and the removal of the screening box 15. The bottom of the return frame 14 is abutted against a top plate 16, and the bottom of the top plate 16 is fixedly connected with a support rod at equal intervals, and the bottom end of the support rod is fixedly connected with a striking plate 17. The bottom of the U-shaped frame 10 is evenly spaced with through-holes for the support rod to pass through, which ensures that the striking plate 17 can move up and down normally. The bottom of the striking plate 17 is abutted against a cam 18 at equal intervals, and the surface of the worm 11 is evenly spaced and connected to a worm gear 19. One end of the intermediate shaft of the worm gear 19 is fixedly connected to one side of the cam 18, and one end of the worm 11 is transmission connected to one end of the intermediate shaft of the crushing roller 6 through a second synchronous belt.

[0032] The implementation principle of a hard disk destruction shredder in the embodiment of the present application is as follows: start the motor, and under the action of the motor and the shredding gear 8, the two shredding rollers 6 perform shredding work. At the same time, under the action of the first synchronous belt and the conveying gear 9, the two conveying rollers 7 rotate relative to each other. When the user destroys the hard disk, he first inserts the hard disk between the two blocking plates 5 through the feed chute. The hard disk will squeeze the two blocking plates 5 to both sides, so that the hard disk abuts between the two conveying rollers 7. The two conveying rollers 7 will automatically convey the hard disk downward, so that the hard disk falls between the two shredding rollers 6 and is shredded. Before the hard disk falls into the two shredding rollers 6, under the action of the return spring rod 4, the two blocking plates 5 will move closer to each other, blocking the feed chute, avoiding the situation where fragments are ejected when the hard disk is shredded, thereby improving the safety of the device. At the same time, when destroying the hard disk, you only need to insert the hard disk downward, and the conveying roller 7 will automatically transport the hard disk downward, which is very convenient and improves the user experience of the device.

[0033] The worm 11 starts to rotate under the action of the second synchronous belt, so that the multiple worm gears 19 drive the cam 18 to rotate at the same time. During the rotation of the cam 18, the top 16 and the return frame 14 are continuously struck. When the cam 18 does not hit the strike plate 17, the pressure plate 13 squeezes the return frame 14 downward under the action of gravity and the small spring rod 12. As the cam 18 rotates continuously, the return frame 14 and the screening box 15 are continuously moved up and down to screen the debris in the screening box 15. The large-sized debris remains in the screening box 15, and the small-sized debris falls into the collecting box 2. The up and down vibration of the screening box 15 can effectively prevent the large-sized debris from blocking the screening box 15, so that the hard disk debris is screened more thoroughly, thereby improving the screening efficiency of the device. The cams 18 on both sides can strike the striking plate 17 synchronously or asynchronously, and both can achieve the up and down vibration of the screening box 15.
