Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a cleaning scraper with stable connection. Background Art

[0002] The toner cartridge of a general printer is composed of a toner bin, a waste toner bin, a photosensitive drum, a charging roller, a magnetic roller or a developing roller, a toner scraper and a cleaning scraper. These components are combined to form a toner cartridge, which is installed inside the printer for developing images. The photosensitive drum, charging roller and cleaning scraper are installed in the plastic shell of the waste toner bin. The cleaning scraper is tangent to the surface of the photosensitive drum and has a certain pressure. When the photosensitive drum rotates with the toner remaining on the surface, it is scraped into the waste toner bin by the cleaning scraper.

[0003] However, when the blade of the cleaning scraper is not lubricated enough or there is too much toner remaining on the surface of the photosensitive drum, the friction between the cleaning scraper and the photosensitive drum will be too great. During the rotation of the photosensitive drum, the cleaning scraper will bend and deform, causing the printer to jam, make abnormal noises, leak waste toner, or print large areas of blackened paper, affecting the normal use of the printer.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0022] like Figure 1-5 As shown, a cleaning scraper with stable connection comprises a blade body 1 and a blade holder assembly; one end of the blade body is a blade edge, and the other end of the blade body is a blade body mounting end;

[0023] The tool holder assembly comprises a lower bracket and an upper pressing frame;

[0024] The lower bracket includes an outer plate 2 and a lower plate 3 vertically fixedly connected to the outer plate, the upper press frame includes an inner plate 4 and an upper plate 5 vertically fixedly connected to the inner plate, the knife body is located between the lower plate and the upper plate, and the blade of the knife body monomer is located on the outside of the knife holder assembly; a plurality of hook structures are provided between the knife body and the lower plate;

[0025] The installation end of the blade body monomer is in contact with the inner plate, the inner plate is in contact with the outer plate, and two sides of the blade body monomer are bonded to the upper plate and the lower plate.

[0026] Thus, during installation, glue is applied to the lower plate, the blade body is placed on the lower plate of the lower bracket, hooked with the lower plate through the hook structure, glue is applied to the upper end of the blade body, the upper plate is placed on the blade body, and the inner plate is fitted with the outer plate, the lower end of the inner plate is inserted between the installation end of the blade body and the outer plate, and the connection between the blade body and the blade holder assembly is completed. After that, the cleaning scraper is installed in the plastic shell of the printer, and the blade edge of the blade body is tangent to the surface of the photosensitive drum with a certain pressure.

[0027] The anti-deformation capability of the blade body monomer can be improved by disposing the lower bracket and the upper pressing frame in a transverse T-shaped structure.

[0028] During implementation, a plurality of upper rib plates 6 are fixed between the upper plate and the inner plate at intervals to improve strength.

[0029] During implementation, a plurality of lower rib plates 7 are fixed between the lower plate and the outer plate at intervals to improve strength.

[0030] During implementation, the hook structure includes a plurality of hooks 8 fixedly mounted on the lower end of the blade body, and the lower plate is provided with hook holes 9 for hooking with the hooks.

When the blade body is subjected to an outward force, the hooks can be transmitted to the lower plate, thereby improving the anti-flipping and anti-bending capabilities of the blade body.

[0031] During implementation, lower mounting holes 10 are provided on both sides and the middle of the lower end of the outer plate, and upper mounting holes 11 are provided on both sides and the middle of the upper end of the lower plate and the upper plate, so as to facilitate installation.

[0032] Specifically, the distance between the upper plate and the blade edge of the blade body is smaller than the distance between the lower plate and the blade edge of the blade body, so as to better press down the blade body to prevent it from being completely deformed.

[0033] Specifically, a slot is provided on the blade body monomer for the hook, a connecting column is welded in the slot, and the connecting column is welded to the hook to complete the connection between the hook and the blade body monomer.

[0034] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
