At this time, the gear 71 is separated from the rack 21, and the magnetic field of the L-shaped rod 791 will adsorb the iron sheet 792, thereby limiting the placement plate 7 and the bottom plate 74 that have rotated 180°; When the placement plate 7 moves to the top of the first rubber pad 31, and the placement groove 72 is located above the positioning groove 311, and the storage information data disk is located at the upper end of the positioning groove 311 and the opening of the positioning groove 311 is blocked, then the air pump 11 is started, and the control valve on the corresponding air pipe 34 is opened, so that the gas in the corresponding first groove 38, the plurality of first holes 32 and the plurality of third holes 39 is extracted along the air pipe 34, the main pipe 35 and the connecting pipe 36, thereby generating negative pressure in the first groove 38, the plurality of first holes 32 and the plurality of third holes 39, and under the action of the negative pressure, the storage information data disk enters the positioning groove 311, so that the storage information data disk is positioned and clamped for installation; It can realize automatic correction and positioning placement of the storage information data disk, effectively avoid the phenomenon that the storage information data disk is placed with the substrate facing up, effectively reduce the probability of information leakage due to the information not being eliminated, with high security, effectively reduce working time and efficiency, and effectively ensure the subsequent information material crushing elimination effect; Then, the third motor 84, the second screw rod 82 and the slider 81 are used to move the first electric push rod 8, the movable rod 76, the support arm 75, the bottom plate 74 and the placement plate 7 forward to their original positions, and the bottom plate 74 and the placement plate 7 are rotated back to their original positions with the assistance of the gear 71 and the rack 21, and then the first electric push rod 8, the movable rod 76, the support arm 75 and the limiting frame 4 are used to reattach the two placement plates 7; Then, the first motor 53 is started to drive the first screw rod 52 to rotate. Since the first screw rod 52 is connected to the moving column 5 through a ball nut pair, the rotation of the first screw rod 52 causes the moving column 5 to move left and right, thereby causing the mounting plate 55 and other components to move left and right, thereby causing the outer cylinder 6 to move directly above the first rubber pad 31 on which the information data disk is placed. Then, the second electric push rod 56 is started to drive the housing 61, the circular plate 62, the outer cylinder 6 and other components to move downward, thereby causing the corresponding first rubber pad 31 and the cylinder 3 to be inserted into the outer cylinder 6, and causing the information data disk adsorbed on the first rubber pad 31 to contact the grinding wheel 65. Then, the second motor 64 is started to drive the grinding wheel 65 to rotate, and the second electric push rod 56 is used to move the rotating grinding wheel 65 downward to grind the information recording layer composed of magnetic materials on the disk storing information data, thereby completing the pulverization elimination of the information material, effectively reducing the probability of incomplete elimination due to block fragments produced by crushing and other methods, effectively reducing the probability of information leakage, etc., with high security, and effectively ensuring the subsequent pulverization elimination effect of information materials.

However, magnetic waste chips are generated during the crushing and elimination operation and are in a splashing state, resulting in a high probability that the magnetic waste chips will randomly splash to the outside and cause pollution, which results in a high probability of interference with subsequent elimination operations.

[0023] In order to solve the above problems, Figure 1 , Figure 2 , Figure 3 , Fig.10 , Fig.11 , Fig.13 and Fig.14 As shown, a second hole 33 extending to the lower end of the first rubber pad 31 and located on the inner side of the first hole 32 is formed downwardly at the bottom end surface of the positioning groove 311, and a mounting carrier is provided for the rubber column 37 through the second hole 33. A mounting groove 371 located on the inner side of the third hole 39 and connected with the lower end of the second hole 33 is formed on the upper end surface of the round body, and the mounting groove 371 is formed. The mounting groove 371 provides a mounting space for components such as a moving plate 376, and the rubber column 37 is arranged in the second hole 33. The disk after the crushing is eliminated is ejected through the rubber column 37. The push rod 374 extending from the lower end into the mounting groove 371 is mounted on the middle part of the lower end of the rubber column 37. The push rod 374 is used to make the rubber column 37 move up and down. The moving plate 376 slidably connected to the mounting groove 371 is set on the lower end of the push rod 374. The moving plate 376 is used to provide a mounting carrier for the push rod 374 and other components. The magnetic block 377 is then mounted on the lower end of the moving plate 376. The second electromagnet 378 located directly below the magnetic block 377 and arranged to repel the magnetic block 377 is set on the bottom end of the inner part of the mounting groove 371. The magnetic block 377 and the second electromagnet 378 are used in conjunction with each other to make the moving plate 376 move upward. The limit plate 373 located in the installation groove 371 is slidably connected to the outer end of the top rod 374, and the elastic member 375 is limited to be installed through the limit plate 373, and the elastic member 375 located on the outer side of the top rod 374 is set between the lower end of the limit plate 373 and the upper end of the movable plate 376, and the movable plate 376 is moved down and returned to its original position through the elastic member 375. The elastic member 375 can be a spring, and the inner wall surface of the installation groove 371 is recessed outward to form a slot, and the slot provides an installation space for the limiter, and then the limiter attached to the upper end of the limit plate 373 is assembled to the slot, and the installation between the limit plate 373 and the installation groove 371 is restricted by the limiter, and the limiter can be a retaining spring 372; An annular electromagnet 63 attached to the lower end of the circular plate 62 is set on the outer end of the outer cylinder 6. The annular electromagnet 63 is used to generate a magnetic field, and an inner cylinder 66 located outside the grinding wheel 65 is installed on the inner wall of the outer cylinder 6. The magnetic waste chips generated by grinding are adsorbed by the inner cylinder 66. Then, a second rubber pad 67 whose lower end surface overlaps with the lower end surface of the outer cylinder 6 and whose upper end is connected to the lower end of the inner cylinder 66 is set on the inner wall of the outer cylinder 6. The second rubber pad 67 is used to prevent the inner cylinder 66 from colliding with the first rubber pad 31. The other ends of multiple first columns 68 arranged in a circular structure and equidistantly installed on the outer end of the inner cylinder 66 all pass through the outer cylinder 6 and are connected to the inner wall of the annular electromagnet 63. The multiple first columns 68 are used in combination to magnetize the inner cylinder 66 and form magnetism.

[0024] When in use, the information storage data disk is first automatically corrected and positioned on the corresponding first rubber pad 31 by means of the third motor 84, the second screw rod 82, the slider 81, the first electric push rod 8, the movable rod 76, the support arm 75, the bottom plate 74, the placement plate 7, the gear 71, the rack 21 and the first electromagnet 73. Then, the information storage data disk is positioned and clamped by means of the air pump 11, the air pipe 34, the first groove 38, the first holes 32 and the third holes 39. Then, the second electric push rod 56 is used to drive the housing 61, the circular plate 62, the outer cylinder 6 and other components to move downward, so that the corresponding first rubber pad 31 and the cylinder 3 are inserted into the inner cylinder 66, and the storage information data disk adsorbed on the first rubber pad 31 is brought into contact with the grinding wheel 65, and then the second motor 64, the grinding wheel 65 and the second electric push rod 56 are used to crush and eliminate the information recording layer composed of the magnetic material on the storage information data disk; At the same time, the circuit of the annular electromagnet 63 is turned on, so that the annular electromagnet 63 generates a magnetic field, and the magnetic field of the annular electromagnet 63 and the plurality of first columns 68 magnetize the inner cylinder 66 and generate magnetism, and the magnetism of the inner cylinder 66 will adsorb the magnetic waste chips generated by the crushing elimination, so as to collect the magnetic waste chips formed by the crushing elimination, effectively reduce the probability of magnetic waste chips randomly splashing to the outside due to grinding and causing pollution, effectively reduce the probability of interference with subsequent elimination operations, and effectively ensure the crushing elimination effect of information materials; After the information material on the disk is crushed, the second electric push rod 56 is first used to drive the housing 61, the circular plate 62, the outer cylinder 6 and other components to move upward, thereby separating the inner cylinder 66 from the cylinder 3 and the first rubber pad 31, and then the air pump 11 is closed, and the control valves on the two air pipes 34 are opened, so as to eliminate the negative pressure of the magnetic disk after the crushing, and then the circuit of the corresponding second electromagnet 378 is connected. Since the second electromagnet 378 and the magnetic block 377 are arranged to repel each other, a repulsive force is generated between the second electromagnet 378 and the magnetic block 377, and under the action of the repulsive force, the magnetic block 377 and the moving plate 376 move upward along the mounting groove 371, and compress the elastic member 375, so that the elastic member 375 generates an elastic force; The upward movement of the moving plate 376 will cause the push rod 374 to move upward, thereby causing the rubber column 37 to move upward, and contact the eliminated disk and exert an upward thrust, thereby lifting the eliminated disk from the positioning groove 311, and then taking the eliminated disk out, thereby realizing convenient material retrieval of the eliminated disk, effectively reducing the probability of obstacles to the removal operation of the eliminated disk due to factors such as restrictions between the eliminated disk and the positioning groove 311, effectively reducing working time and efficiency, and effectively ensuring the pulverization elimination effect of information materials; Embodiment 3: An air pump 11, an air pipe 34, a first groove 38, a plurality of first holes 32, a plurality of third holes 39, a main pipe 35 and a connecting pipe 36 are used to position and clamp the storage information data disk, and then the second motor 64 and the grinding wheel 65 are used to crush and eliminate the information material of the clamped storage information data disk, and the annular electromagnet 63, a plurality of first columns 68 and an inner cylinder 66 are used to collect the generated magnetic waste chips by adsorption, and then the collected magnetic waste chips are directly cleaned after the elimination operation is completed. However, the magnetic waste chips generated in the crushing elimination operation are prone to be in the form of flakes, resulting in a high probability of incomplete elimination of the magnetic waste chips, resulting in a high probability of information leakage.

The piston 5031 is used to provide a mounting carrier for the round rod 503 on the one hand, and to lift the collected magnetic waste chips on the other hand. The third rubber pad 504 connected to the recovery cylinder 506 is installed on the upper end of the recovery cylinder 506, and the third rubber pad 504 is used to prevent the outer cylinder 6 from directly colliding with the recovery cylinder 506.

[0026] When in use, the information storage data disk is first automatically corrected and positioned on the corresponding first rubber pad 31 by means of the third motor 84, the second screw rod 82, the slider 81, the first electric push rod 8, the movable rod 76, the support arm 75, the bottom plate 74, the placement plate 7, the gear 71, the rack 21 and the first electromagnet 73. Then, the information storage data disk is positioned and clamped by means of the air pump 11, the air pipe 34, the first groove 38, the first holes 32 and the third holes 39. Then, the second electric push rod 56 is used to drive the outer shell 61, the circular plate 62, the outer cylinder 6 and other components to move downward, so that the corresponding first rubber pad 31 and the cylinder 3 are inserted into the inner cylinder 66, and the storage information data disk adsorbed on the first rubber pad 31 is brought into contact with the grinding wheel 65. Then, the second motor 64, the grinding wheel 65 and the second electric push rod 56 are used to crush and eliminate the information recording layer composed of magnetic materials on the storage information data disk. At the same time, the annular electromagnet 63, the plurality of first columns 68 and the inner cylinder 66 are used to adsorb the magnetic waste chips generated by the crushing elimination.
