In addition, the terms "first", "second", "third", "upper, lower, left, right", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present invention, unless otherwise clearly stipulated and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The utility model provides a structure of a cleaning scraper for preventing carbon powder from sticking to a roller. Figure 1 and Figure 2 As shown, further, it includes a metal knife holder 1, the structure of the metal knife holder 1 is an L-shaped structure, a blade 11 is provided at the top position of one side of the metal knife holder 1, and an existing cleaning scraper 4 is provided on one side of the metal knife holder 1. The existing cleaning scraper 4 is composed of a base frame 41 and a cleaning knife 42. A base frame 41 is provided on one side of the metal knife holder 1, and a cleaning knife 42 is adhered to the top position of the surface of the base frame 41.

[0023] like Figure 2 and Figure 5 As shown, a positioning mechanism 2 is provided on the surface of the metal tool holder 1, and the interior of the positioning mechanism 2 includes a positioning port 21, a positioning plate 22 and a protrusion 23. Positioning plates 22 are fixed on both sides of the top position of the metal tool holder 1, and protrusions 23 are fixed on the surfaces of both sides of the positioning plate 22. The surface of the protrusion 23 fits tightly with the surface of the blade 11. The surface of the blade 11 is provided with a positioning port 21, and the positioning port 21 and the positioning plate 22 are plugged into each other.

[0024] When in use, place the blade 11 to one side of the metal knife holder 1, so that the positioning port 21 is sleeved onto the surface of the positioning plate 22, quickly position and place the metal knife holder 1, and fix the metal knife holder 1 under the action of the protrusion 23, so as to realize the multifunctionality of the cleaning scraper for easy positioning and placement of the metal knife holder 1.

[0025] like Figure 4 and Figure 5As shown, a fixing mechanism 3 is provided between the metal knife holder 1 and the blade 11. The fixing mechanism 3 is composed of a perfusion component 31 and an adhesive glue 32. The metal knife holder 1 and the blade 11 are adhered with adhesive glue 32. The surface of the metal knife holder 1 is provided with a perfusion component 31. The interior of the perfusion component 31 includes a rubber sleeve 311 and a perfusion hole 312. The surface of the metal knife holder 1 is fixed with a rubber sleeve 311. The rubber sleeve 311 is located on one side of the blade 11. The surface of the metal knife holder 1 is provided with a perfusion hole 312, and the perfusion hole 312 is communicated with the rubber sleeve 311.

[0026] During use, the metal knife holder 1 and the blade 11 are glued and fixed by the adhesive 32, and then glue can be injected into the filling hole 312 through the adhesive sleeve 311 to reinforce the metal knife holder 1 and the blade 11, so that the cleaning scraper can be subjected to parallel force, stable and balanced during use.

[0027] Working principle: When in use, first of all, since the metal knife holder 1 is an L-shaped structure, it is stronger than the base frame 41. At the same time, when in use, the blade 11 can be placed on one side of the metal knife holder 1, so that the positioning port 21 is sleeved on the surface of the positioning plate 22, and the metal knife holder 1 is quickly positioned and placed, and the metal knife holder 1 is fixed under the action of the protrusion 23, so that the cleaning scraper is easy to position and place the metal knife holder 1 multifunctionally, thereby improving the convenience of positioning the cleaning scraper on the metal knife holder 1.

[0028] At the same time, during use, the metal knife holder 1 and the blade 11 are glued and fixed under the action of the adhesive 32, and then glue can be injected into the filling hole 312 through the adhesive sleeve 311 to reinforce the metal knife holder 1 and the blade 11, so that the cleaning scraper can be subjected to parallel force stably and evenly during use, thereby reducing the problem of the toner cartridge not being scraped cleanly by the cleaning scraper, resulting in bottom dust and carbon powder sticking to the roller, and finally completing the use of the cleaning scraper.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
