Description

Technical Field

[0001] This utility model relates to the technical field of toner cartridges, and in particular to a toner control scraper and a toner cartridge toner control structure. Background Technology

[0002] The magnetic roller shell of the toner cartridge is equipped with a toner control blade. The toner control blade is used to control the toner on the magnetic roller (magnetic developing roller). Currently, existing toner control blades generally consist of a blade holder and a blade mounted on the blade holder. The blade holder is made of metal with a thickness of 1.2-2.0 mm, and the blade is a PU sheet with a thickness of 1.6-2.2 mm. When manufacturing this type of toner control blade, the blade holder and the blade need to be manufactured separately first, and then assembled. The process steps are relatively complex and the production cost is relatively high. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a powder control scraper to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a powder control scraper is designed, comprising: a scraper body, wherein the scraper body is made of PE material and has a long strip-shaped structure.

[0006] Using the above technical solution, the scraper body of this technology is made of PE material. Taking advantage of the relatively hard properties of PE material, the scraper body can be directly connected to the magnetic roller shell on the drum and can meet the powder control requirements of the magnetic roller. Compared with the existing powder control scraper which consists of two parts, a blade holder and a blade, the powder control scraper of this technology has only one part. The structure is simple, the manufacturing process is more simplified, it is easy to produce and process, and it can reduce production costs.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the thickness of the scraper body is 0.1-0.3 mm. Controlling the thickness of the scraper body to 0.1-0.3 mm can save on manufacturing materials and reduce production costs.

[0009] In some embodiments, the scraper body has a rectangular structure.

[0010] In some embodiments, the thickness of the scraper body is 0.18 mm.

[0011] In some embodiments, the scraper body is provided with a row of strip-shaped mounting holes, the length direction of which is consistent with the width direction of the scraper body. When a screw passes through the strip-shaped mounting holes on the scraper body and is threaded into the magnetic roller shell of the toner cartridge, the scraper body can be fixed. The fixed position of the scraper body can be adjusted through the strip-shaped mounting holes, thereby adjusting the distance between the scraper body and the magnetic roller and adjusting the powder control effect.

[0012] According to another aspect of the present invention, a toner cartridge control structure is designed, including a magnetic roller housing, a magnetic roller rotatably connected to the magnetic roller housing, and the aforementioned scraper body, wherein the scraper body is disposed on one side of the magnetic roller and connected to the magnetic roller housing.

[0013] In some embodiments, the scraper body and the magnetic roller housing are connected by adhesive bonding.

[0014] In some embodiments, the scraper body and the magnetic roller housing are connected by a plurality of screws.

[0015] In some embodiments, the scraper body is pressed onto the magnetic roller housing by a strip pressure plate, and the strip pressure plate is fixed to the magnetic roller housing by screws. Attached Figure Description
