Description

TECHNICAL FIELD

[0001] The utility model relates to data security technical field more specifically, it relates to a kind of data shredding device convenient to use. BACKGROUND

[0002] Under the background that information security is increasingly important today, as a key tool to protect sensitive information, the optimization of design and function of data shredding device is particularly important, however, there are still some significant limitations in the existing data shredding device technology.

[0003] First, the most prominent problem in the prior art is the lack of effective material guiding device, most shredding devices use the simple way of directly placing data between two shredding rollers for operation, this design seems direct, but there are many drawbacks in actual use, the most obvious problem is easy to cause internal jamming, when a large amount of data is simultaneously put in or the thickness of data is uneven, it is easy to cause blockage at the entrance of shredding roller, which not only will interrupt the shredding process, reduce work efficiency, but also may cause equipment damage, more seriously, frequent jamming may force the operator to intervene the equipment operation improperly, increase safety risk, in addition, the lack of material guiding device also means that data may not be uniformly entered into the shredding roller, resulting in inconsistent shredding effect, some parts may not be fully shredded, so as to fail to meet the requirements of information security.

[0004] Secondly, another major defect in the prior art is the difficulty of equipment maintenance, this problem is mainly reflected in the design of the back disassembly plate of the equipment, the installation and disassembly process of the disassembly plate of most equipment is complicated, usually need to use special tools, this design seriously affects the daily maintenance efficiency of the equipment, for example, when paper jammed in the shredding roller needs to be cleaned or regular inspection is needed, the operator may need to spend a lot of time and effort to open the equipment, which not only increases the maintenance cost, but also may cause the equipment to be unable to be processed in time when emergency repair is needed, prolong the downtime, affect work efficiency.

[0005] In addition, some manufacturers try to solve the above maintenance problems by introducing quick disassembly mechanisms, but these solutions often sacrifice stability and safety in favor of ease of disassembly, allowing operators to perform maintenance more quickly, but they often sacrifice structural stability and safety, and these quick disassembly devices are prone to looseness, wear and even complete failure over time and frequent use. More seriously, this lack of structural stability can pose a serious safety hazard, as the device will typically generate continuous vibrations during operation, and if the disassembly plate is not securely fixed, prolonged vibrations can cause the disassembly plate to gradually loosen or even suddenly fall off during operation, which not only interrupts the shredding process, but also exposes the high-speed shredding rollers to potential harm to nearby operators. At the same time, the loosening or falling off of the disassembly plate can also cause the shredded material to leak, which defeats the purpose of using the shredding device to protect sensitive information.
