Description

Technical Field

[0001] The utility model relates to the field of printing consumables, in particular to an external tool for toner filling and filtering of a toner cartridge. Background Art

[0002] The basic structure of a toner cartridge is generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. According to the different photosensitive materials, it can be basically divided into three types: OPC drum (organic photoconductive material), toner cartridge (Se selenium) and ceramic drum (a-si ceramic). From the perspective of life, the life of OPC drum is relatively short, generally only about 3,000 pages, and of course the price is also the cheapest. The life of Se drum is about 9,000 pages, and the life of a-si drum can reach 90,000 pages, and the price is naturally rising accordingly.

[0003] After searching, the current Chinese patent announcement number is: CN 220357429 U, which provides an external toner cartridge filling and filtering tool. This patent fills the powder bin with powder after installation, so that the toner can be filtered and dispersed before entering the powder bin, avoiding the agglomerated or granular toner from entering the powder bin. Through this powder filling and filtering device, the toner can be filtered and dispersed in a double layer to ensure the filtering and dispersion effect.

[0004] Although the above patent can perform double-layer filtering and breaking up of carbon powder to ensure the filtering and breaking up effect, the above-mentioned external tool for toner cartridge filling and filtering still has the following problems: the carbon powder first falls on gear one, and then the carbon powder is dispersed to the teeth through the arc-shaped landslide protrusion, and the teeth of gear one and the teeth of the tooth ring crush the carbon powder against each other, and the carbon powder is crushed by the teeth, which easily causes the non-agglomerated carbon powder to be squeezed together, and then the carbon powder is squeezed into blocks, which causes poor treatment effect of the carbon powder, etc.

[0005] In view of the above problems, an external toner cartridge filling and filtering tool is proposed. Utility Model Content

[0006] The utility model aims to provide an external tool for toner filling and filtering of a toner cartridge, which solves the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a toner cartridge powder filling and filtering external tool, comprising a toner cartridge, a powder filling tube is arranged on the top of the toner cartridge, a discharge tube is inserted into the inside of the powder filling tube, a tank body is fixedly installed on the top of the discharge tube, a sealing cover is threadedly connected to the top of the tank body, a rotating shaft is rotatably connected to the inside of the sealing cover, a crank is fixedly installed on the upper end of the rotating shaft, a filter screen is fixedly installed inside the tank body, and a crushing piece is fixedly installed on the surface of the rotating shaft.

[0008] By adopting the above technical solution, the rotating shaft and the crank are rotated to make the crushing sheet rotate on the filter net, and the filtered carbon powder is dispersed to prevent the carbon powder from agglomerating.

[0009] As a further description of the above technical solution: a valve is fixedly installed on the discharge pipe.

[0010] By adopting the above technical solution and setting the valve, it is convenient to control the discharge amount of carbon powder.

[0011] As a further description of the above technical solution: the sealing cover is provided with a groove, and the shape of the groove is a triangular groove.

[0012] By adopting the above technical solution and providing the groove, the friction force when the sealing cover is rotated can be increased, thereby facilitating the rotation of the sealing cover.

[0013] As a further description of the above technical solution: a disc is fixedly sleeved on the surface of the rotating shaft, the disc is rotatably connected inside the sealing cover, a protrusion is fixedly installed on the top of the disc, the protrusion is arranged in an inclined shape, a limiting rod is fixedly installed inside the sealing cover, and a movable plate is slidably connected on the surface of the limiting rod.

[0014] By adopting the above technical solution and setting the limiting rod, it is convenient to limit the movable plate, so that the movable plate can only move horizontally, thereby preventing the movable plate from swinging.

[0015] As a further description of the above technical solution: a baffle is fixedly installed on one end of the limiting rod, a spring is movably sleeved on the limiting rod, two ends of the spring are respectively fixedly connected to the movable plate and the side opposite to the baffle, a knocking ball is fixedly installed on one side of the movable plate, the knocking ball contacts the inner wall of the sealing cover, a connecting rod is fixedly installed on the movable plate, a fixed rod is fixedly installed on the bottom of the connecting rod, and a roller is rotatably connected to the bottom of the fixed rod.

[0016] By adopting the above technical solution, the knocking ball knocks the inside of the sealing cover, so that the sealing cover and the tank body shake, which makes it easier to shake the carbon powder inside the tank body, and makes it easier for the carbon powder to pass through the filter screen.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] 1. The utility model provides an external toner cartridge toner filling and filtering tool, which first filters the toner through a filter, then rotates the rotating shaft and the crank to rotate the crushing piece on the filter, and disperses the filtered toner to prevent the toner from agglomerating, thereby preventing the agglomerated toner from entering the interior of the toner cartridge to the greatest extent.

[0019] 2. The utility model provides an external toner cartridge filling and filtering tool, which uses a knocking ball to knock the inside of the sealing cover to shake the sealing cover and the tank body, thereby facilitating the shaking of the carbon powder inside the tank body, thereby facilitating the carbon powder to pass through the filter screen to prevent the filter screen from being blocked.

[0028] Combination Figure 1-Figure 4 The utility model discloses an external tool for filling and filtering toner cartridges, comprising a toner cartridge 1, a powder filling tube 2 is arranged on the top of the toner cartridge 1, a discharge tube 3 is inserted into the inside of the powder filling tube 2, a tank body 5 is fixedly installed on the top of the discharge tube 3, a sealing cover 6 is threadedly connected to the top of the tank body 5, a rotating shaft 7 is rotatably connected to the inside of the sealing cover 6, a crank 8 is fixedly installed on the upper end of the rotating shaft 7, a filter screen 11 is fixedly installed inside the tank body 5, and a crushing piece 10 is fixedly installed on the surface of the rotating shaft 7.

[0029] Rotate the sealing cover 6 and remove it from the tank body 5, pour the carbon powder into the tank body 5, install the sealing cover 6 onto the tank body 5, filter the carbon powder through the filter 11, rotate the rotating shaft 7 and the crank 8, rotate the crushing piece 10 on the filter 11, and disperse the filtered carbon powder to prevent the carbon powder from agglomerating, thus avoiding the agglomerated carbon powder from entering the interior of the toner cartridge 1 to the greatest extent.

[0030] A valve 4 is fixedly installed on the feeding pipe 3 .

[0031] The sealing cover 6 is provided with a groove 9 which is in the shape of a triangular groove.

[0032] A disc 12 is fixedly sleeved on the surface of the rotating shaft 7, and the disc 12 is rotatably connected inside the sealing cover 6. A protrusion 13 is fixedly installed on the top of the disc 12, and the protrusion 13 is arranged in an inclined shape. A limiting rod 19 is fixedly installed inside the sealing cover 6, and a movable plate 14 is slidably connected to the surface of the limiting rod 19.

[0033] A baffle 18 is fixedly installed at one end of the limiting rod 19, and a spring 20 is movably sleeved on the limiting rod 19. Both ends of the spring 20 are fixedly connected to the opposite sides of the moving plate 14 and the baffle 18 respectively. A knocking ball 21 is fixedly installed on one side of the moving plate 14, and the knocking ball 21 contacts the inner wall of the sealing cover 6.
