Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing consumables, and in particular to an automatically unsealed toner cartridge. Background Technology
[0002] Most toner cartridges on the market currently use a completely sealed toner supply compartment to prevent the developer toner from becoming ineffective due to moisture, leakage, or contamination. This also facilitates storage and transportation, effectively extending shelf life. Therefore, most toner cartridges use a manually opened toner supply compartment. Before installing the cartridge, the sealing film must be manually pulled open. To facilitate opening the sealing film, an outlet for manually pulling the sealing film must be provided on one side of the toner supply compartment. A specially designed sealing plug is also needed to prevent developer toner leakage and contamination or moisture-induced developer toner ineffectiveness after opening. Additionally, a sealing film outlet must be provided at the corresponding position on the end cap of the manually opened side. Therefore, the relevant components of this end cap must be carefully designed to avoid or bypass this outlet to prevent interference.
[0003] Meanwhile, as an important component of office and printing equipment, the need to manually unseal the toner cartridge before use is cumbersome and inconvenient. Although various instructions, tips, and error-proofing measures have been thoughtfully added, a significant proportion of cartridges are still installed into the equipment without being fully unsealed or with incomplete unsealing, resulting in printed failures and seriously affecting printing quality and work efficiency. Therefore, it is necessary to design an automatically unsealing toner cartridge. Utility Model Content
[0004] To address the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a toner cartridge toner cartridge that automatically opens as the toner cartridge is used, simplifying the cumbersome operation before installing the toner cartridge while retaining the advantages of a fully sealed toner cartridge.
[0005] To achieve the above objectives, this utility model provides the following solution: An automatically unsealed toner cartridge includes a toner cartridge for loading toner, a toner outlet on the toner cartridge, a stirring rod assembly driven by gears inside the toner cartridge inside the toner cartridge, a sealing film on the toner outlet, a stirring blade for stirring toner on one side of the stirring rod assembly, and a plurality of fixing posts on the stirring rod assembly, wherein the sealing film and the stirring blade are sequentially mounted on the fixing posts.
[0006] Furthermore, in this invention, the powder outlet is located on one side of the powder hopper, and the outer periphery is a welding surface for connecting the sealing membrane. The sealing membrane is connected to the welding surface by a welding device.
[0007] Furthermore, the stirring rod assembly of this utility model includes shaft holes and through holes on both sides of the powder hopper, a roller body that rotates at a fixed point is installed on the shaft holes and through holes, a gear connecting groove for installing a gear is provided on one end of the roller body at the through hole, and an installation plane for setting a fixing post is provided on one side of the roller body.
[0008] Furthermore, the fixing post in this utility model is mushroom-shaped.
[0009] Furthermore, the sealing film and stirring blades of this invention are provided with snap holes for fastening onto the fixing post.
[0010] In summary, the advantages of this utility model over the prior art are: This invention features a simple structure. A sealing film automatically opens from the toner cartridge's toner supply compartment during use, allowing the toner outlet to open and dispense toner. This process eliminates the need for manual opening of the sealing film. Furthermore, because it's not manually opened, the sealing film can be wound around the stirring rod assembly, without affecting the toner dispensing effect. There's no need to leave an outlet for removing the sealing film, and the side cover components don't need to be designed to avoid or bypass this outlet, allowing for a more compact internal space. This solution offers various advantages for both the sealing and opening of the toner cartridge. The sealing structure is simple and easy to design, requiring no obstruction of other components. Opening is manual and thorough, resulting in significant improvements in printing quality and work efficiency. Attached Figure Description

Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 4The present invention preferably provides an automatically unsealed toner cartridge, including a toner cartridge 1 for loading toner, a toner outlet 11 provided on the toner cartridge 1, a stirring rod assembly 2 driven by gears inside the toner cartridge 1 provided inside the toner cartridge 1, a sealing film 3 sealed on the toner outlet 11, a stirring blade 4 for stirring toner provided on one side of the stirring rod assembly 2, and a plurality of fixing posts 5 provided on the stirring rod assembly 2, the sealing film 3 and the stirring blade 4 being sequentially installed on the fixing posts 5. The toner outlet is sealed with a sealing film welded using welding equipment. The sealing film is welded around the toner outlet. When subjected to external force, the weld on the sealing film will detach. Therefore, a stirring rod assembly is installed. One end of the sealing film is connected to the stirring rod assembly via a fixing post. The stirring rod assembly is connected to the gears inside the toner cartridge. Therefore, when the gears inside the toner cartridge rotate, they will drive the stirring rod assembly to rotate. The fixing post can then drive the sealing film to wrap around the stirring rod assembly and simultaneously pull the sealing film, causing it to detach from the toner outlet, opening the toner outlet and allowing the toner to flow out. During the rotation of the stirring rod assembly, the stirring blades, which are also installed on the fixing post, will also rotate, making the toner dispensing smoother.
[0013] In this invention, the powder outlet 11 is located inside the powder hopper 1, and its outer periphery forms a welding surface for connecting the sealing membrane 3. The sealing membrane 3 is connected to the welding surface by a welding device. Common specialized welding devices are thermal welding devices or laser welding devices. After the welding surface is welded to the sealing membrane, the welded sealing membrane can be removed by pulling it from one end with external force.
[0014] The stirring rod assembly 2 of this invention includes shaft holes 21 and through holes 22 on both sides of the powder hopper 1. A roller body 23 with fixed-point rotation is mounted on the shaft holes 21 and through holes 22. A gear connecting groove 24 for mounting a gear is provided on one end of the roller body 23 at the through hole 22. A mounting plane 25 for mounting a fixing post 5 is provided on one side of the roller body 23. The shaft holes and through holes are used to position the shaft body for fixed-point rotation. The through hole is for mounting a gear at one end of the roller body. This mounting is achieved through the gear connecting groove. The gear on one side of the roller body can connect with the gear inside the toner cartridge, thereby allowing the roller body to rotate. The mounting plane is a flat surface on one side of the roller body for mounting the fixing post and for ensuring smooth and secure installation of the sealing film and stirring blades.
[0015] The fixing post 5 described in this invention is mushroom-shaped. This shape makes it difficult for the sealing film and stirring blade to fall out after they are installed.
[0016] In this invention, the sealing membrane 3 and the stirring blade 4 are provided with snap holes 31 for fastening onto the fixing post 5. During installation, the snap holes of the sealing membrane are first inserted into the fixing post, and then the stirring blade is inserted into the fixing post, pressing the sealing membrane between them and tightening it.
[0017] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
