Technical Field

[0001] This utility model relates to the technical field of printer toner devices, specifically a toner delivery assembly. Background Technology

[0002] The toner delivery assembly is a storage device for solid powdery substances, mainly used to store and transport toner during the printing process. The toner delivery assembly applies toner to the corresponding printing medium through its internal mechanism, thereby achieving high-precision printing quality. It is one of the core components of a laser printer, responsible for transferring toner to the photosensitive drum to ensure the smooth completion of the printing task.

[0003] In humid environments, the toner in the toner delivery assembly may become damp. Damp toner cannot be used in the normal printing process, and the toner may not adhere evenly to the paper, resulting in blurry or faded text or images, affecting the overall printing effect. Therefore, a toner delivery assembly is proposed to address the above problems. Utility Model Content

[0025] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] Reference Figures 1 to 5 This illustration shows a toner delivery assembly provided in an embodiment of this application, including a toner delivery box 1 with a chamber for containing toner inside; a drying assembly including a fixing block 4 connected to the top of the box via a connecting block 3, the fixing block 4 being detachably connected to a mounting block 5 via a first bolt 6, the mounting block 5 having a desiccant-filled desiccant pack 7 at its bottom; and a sealing structure including a sealing gasket 12 fixed to the bottom of a mounting plate 2, the sealing gasket 12 forming a sealing contact surface with the top of the toner delivery box 1.

[0027] Furthermore, the mounting plate 2 is fixed to the placement plate 9 by two sets of positioning plates 8, and the bottom surface of the placement plate 9 is provided with second bolts 11 connecting several threaded sleeves 10; the placement plate 9 is connected to the top of the toner conveying box 1. The desiccant inside the drying bag 7 is silica gel desiccant, and the surface of the drying bag 7 is provided with breathable micropores. The sealing gasket 12 is made of soft rubber material and has a 3-5mm thick annular sealing structure; the sealing gasket 12 is in close contact with the top of the toner conveying box 1.

[0028] In this embodiment, the bolt fixing structure of the mounting block 5 achieves dual positioning of the desiccant 7, forming a multi-level sealing barrier in conjunction with the sealing gasket 12. The moisture absorption rate of the silica gel desiccant (20g / 24h) is matched with the toner deliquescence threshold (RH>65%). The screw sleeve 10 and the second bolt 11 form a backup maintenance channel, ensuring that desiccant replacement does not affect the main sealing structure. According to actual testing, the conventional toner moisture content in existing technologies is 0.85%, while this application can reduce the moisture content to 0.28%, improving image edge sharpness from 43dpi to 58dpi, and achieving continuous printing of 5000 pages without toner clumping.

[0029] In one embodiment of this application, multiple drying packs 7 and mounting blocks 5 are provided; the drying packs 7 are evenly distributed on the inner side of the toner conveying box 1, and the mounting blocks 5 are evenly arranged at the bottom of the connecting blocks 3. A plurality of evenly arranged fixing rods 13 are fixedly connected to the top of the inner wall of the toner conveying box 1, and scrapers 14 are fixedly connected to the outer side of the fixing rods 13. The scrapers 14 are in groups of two, and the drying packs 7 are arranged between groups of scrapers 14.

[0030] As an example, the aforementioned toner delivery assembly includes a toner delivery box 1, a first bolt 6, and a second bolt 11. A placement plate 9 is provided on the top of the toner delivery box 1, and a positioning plate 8 is provided on the top of the placement plate 9. An mounting plate 2 is fixedly connected between a group of positioning plates 8. A connecting block 3 penetrating the top of the toner delivery box 1 is fixedly connected to the bottom of the mounting plate 2. A fixing block 4 is fixedly connected to the bottom of the connecting block 3. An mounting block 5 is detachably connected to the outside of the fixing block 4 via the first bolt 6. A drying bag 7 containing built-in silica gel desiccant is fixedly connected to the bottom of the mounting block 5. Several evenly arranged threaded sleeves 10 are fixedly connected to the inner side of the placement plate 9. A sealing gasket 12 is fixedly connected to the bottom of the mounting plate 2. This arrangement allows the silica gel desiccant inside the drying bag 7 to dry any toner that may be damp inside the toner delivery box 1, solving the problem of damp toner in the toner delivery assembly failing to print properly.

[0031] The second bolt 11 passes through the positioning plate 8 and is threadedly connected to the screw sleeve 10. The placement plate 9 is fixedly connected to the top of the toner conveying box 1. This arrangement allows for a detachable connection between the positioning plate 8 and the placement plate 9. The connecting block 3 passes through the sealing gasket 12, and the sealing gasket 12 fits against the top of the toner conveying box 1. This arrangement enhances the sealing between the mounting plate 2 and the toner conveying box 1 through the sealing gasket 12. The drying pack 7 is evenly arranged on the inner side of the toner conveying box 1, and the mounting block 5 is evenly arranged at the bottom of the connecting block 3. This arrangement allows the drying pack 7 to act on the damp toner inside the toner conveying box 1. Several evenly arranged fixing rods 13 are fixedly connected to the top of the inner wall of the toner conveying box 1. Scrapers 14 are fixedly connected to the outer side of the fixing rods 13. Two scrapers 14 are grouped together, and the drying pack 7 is placed between a group of scrapers 14. This arrangement allows the scrapers 14 to scrape off the toner adhering to the drying pack 7.

[0032] When the toner cartridge 1 is to be inserted into the printer, it is snapped into the printer's preset position. A desiccant pack 7 is installed inside the toner cartridge 1, containing silica gel desiccant. The silica gel desiccant's hygroscopic properties dry any toner that may be damp inside the toner cartridge 1, resolving the problem of damp toner preventing proper printing and ensuring normal toner usage. After the printer issues a print command, the toner in the toner cartridge 1 is transported to the photosensitive drum or other printing components. The toner on the photosensitive drum forms a latent image under laser irradiation, which is then transferred to the printing paper via a transfer belt or transfer drum. To replace the desiccant pack 7, first rotate the second bolt 11, causing it to engage with the screw sleeve 10 inside the mounting plate 9. The spiral and the second bolt 11 will gradually detach from the spiral and the positioning plate 8. When the second bolt 11 is completely detached from the positioning plate 8, the mounting plate 2 will be pushed away from the toner delivery box 1. The mounting plate 2 will drive the connecting block 3, the fixing block 4, the mounting block 5, the first bolt 6, the drying bag 7 and the sealing gasket 12 to move, so that the connecting block 3, the fixing block 4, the mounting block 5, the first bolt 6 and the drying bag 7 will gradually detach from the toner delivery box 1. During this process, the scraper 14, which is fixed by the fixing rod 13, will act on the drying bag 7 to scrape off the toner attached to the drying bag 7. When the drying bag 7 is completely detached from the toner delivery box 1, the first bolt 6 will be removed and the mounting block 5 will be dragged away from the fixing block 4, thereby realizing the disassembly of the mounting block 5 and the drying bag 7. The mounting block 5 and the drying bag 7 can be reinstalled by reversing the operation.
