[0002] Laser printing technology uses a laser beam to quickly "project" digital graphics or documents onto a photosensitive surface. Electron discharge occurs at the location hit by the laser beam, and then due to static electricity, it attracts some fine "ink" like a magnet, and the printing effect appears.

[0003] The powder knife is an important component in the toner cartridge of a laser printer. Its function is to control the toner delivered to the developing roller to a reasonable thickness in order to control the amount of powder applied. The existing powder knife structure still has some shortcomings to a certain extent. The powder knife structure currently on the market is relatively troublesome to install, and the staff needs to turn multiple bolts to achieve its installation and fixation. This makes it impossible to stably install the grinding plate on the surface of the structure body when the powder knife structure is in use, making it inconvenient to regularly inspect and replace the grinding plate during the use of the powder knife structure; during the use of the existing laser printer, the powder outlet end of the printer will produce different degrees of vibration, which will cause the powder knife to leak powder. This makes it easy for the powder knife to leak powder when the powder knife structure is used, which is easy to affect the typing effect of the printer, and the staff also need to clean the surface of the powder knife.

[0024] During implementation, the user prevents the grinding plate 101 from being on the surface of the structural body 1, so that the grinding plate 101 drives the mounting block 202 to slide inside the guide groove 201, and the grinding plate 101 is guided under the joint action of the guide groove 201 and the mounting block 202.

When the user needs to inspect and replace the grinding plate 101, the user can remove the grinding plate 101 from the surface of the structural body 1 and inspect and replace the grinding plate 101, so as to realize the function of the powder knife structure to facilitate the installation of the grinding plate 101.

[0025] Furthermore, if Figure 3 and Figure 6 As shown, a powder leakage prevention mechanism 3 is provided on the surface of the structural body 1, and the interior of the powder leakage prevention mechanism 3 includes a buffer plate 301, a rubber plate 302 and a powder leakage prevention group 303. The powder leakage prevention group 303 is provided on the surface of the structural body 1, and the powder leakage prevention group 303 is composed of a fixed frame 3031 and a spring assembly 3032. The surface of the structural body 1 is installed with a fixed frame 3031, and the surface of the fixed frame 3031 is provided with a rubber plate 302 for preventing powder leakage. The surface of the rubber plate 302 is installed with a buffer plate 301 for shock absorption.

The inner wall of the fixed frame 3031 is installed with spring assemblies 3032 with equal intervals, and one end of the spring assembly 3032 is fixed to the surface of the buffer plate 301.

[0026] During implementation, the staff can accurately install the structural body 1 into the laser printer through the positioning installation groove 102. After the installation is completed, the powder outlet of the laser printer will be aligned with the top surface of the grinding plate 101, and the rubber plate 302 will fit the powder outlet of the laser printer at this time. The rubber plate 302 can shrink to a certain extent under the elastic force of the spring assembly 3032 inside the fixed frame 3031, so that the buffer plate 301 drives the rubber plate 302 to fit perfectly to the powder outlet of the printer.

[0027] Working principle: When in use, first place the structural body 1 at the designated position, and the user places the grinding plate 101 on the surface of the structural body 1, so that the grinding plate 101 drives the mounting block 202 to slide inside the guide groove 201, and the grinding plate 101 is guided under the joint action of the guide groove 201 and the mounting block 202. At this time, the mounting block 202 drives the anti-dropping clamp 2031 to be clamped into the anti-dropping clamping groove 2032, and the grinding plate 101 is clamped under the clamping action of the anti-dropping clamp 2031 and the anti-dropping clamping groove 2032. 101 is stably installed on the surface of the structural body 1. When the user needs to inspect and replace the grinding plate 101, the user can remove the grinding plate 101 from the surface of the structural body 1 and inspect and replace the grinding plate 101 to realize the function of the powder knife structure to facilitate the installation of the grinding plate 101, so that the grinding plate 101 can be stably installed on the surface of the structural body 1 when the powder knife structure is used, so that the powder knife structure can regularly inspect and replace the grinding plate 101 during use.

[0028] Subsequently, the appearance of the structural body 1 was adjusted to reduce the production cost. The R angle at the front end of the grinding plate 101 was changed to a flat angle to reduce the torque of the powder knife during operation. The surface of the blade of the grinding plate 101 was polished to reduce the problem of vertical stripes printed when the powder knife was used.

[0029] Subsequently, the staff can accurately install the structural body 1 into the laser printer through the positioning installation groove 102. After the installation is completed, the powder outlet of the laser printer will be aligned with the top surface of the grinding plate 101, and the rubber plate 302 will fit the powder outlet of the laser printer. The rubber plate 302 can shrink to a certain extent under the elastic force of the spring assembly 3032 inside the fixed frame 3031, so that the buffer plate 301 drives the rubber plate 302 to fit perfectly to the powder outlet of the printer. At this time, the vibration generated when the powder outlet is discharged will be damped by the spring assembly 3032 inside the spring assembly 3032. 3032 is buffered, so that the printing powder can accurately reach the grinding plate 101, so that there will be no powder leakage due to vibration, and the buffer plate 301 also has a certain buffering effect, which enhances the shock absorption effect of the rubber plate 302 and improves the anti-powder leakage function of the grinding plate 101, so as to realize the function of the powder knife structure to prevent powder leakage, so that the powder knife structure will not leak powder when used, and will not affect the typing effect of the printer, and the staff does not need to clean the powder knife, and finally completes the use of the powder knife structure.
