Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a waste toner box with magnetic positioning. Background Technology

[0002] The waste toner cartridge plays a crucial role in a printer. Its primary function is to collect waste toner generated during the printing process. This waste toner is usually mixed with paper scraps and other debris from the paper itself. Reusing it could scratch the drum unit, leading to decreased print quality, blurry prints, and black streaks. Therefore, the waste toner cartridge ensures a smooth printing process and maintains print quality.

[0003] The waste toner cartridge needs to be replaced after it is full to maintain the printer's waste toner collection function. Currently, the waste toner cartridge is mainly installed and removed by aligning a positioning pin with a positioning hole on the printer. However, this method often results in misalignment of the positioning hole during replacement, making the process time-consuming and laborious. It can also lead to loose connections, causing toner leakage and contaminating the printer. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model proposes a waste powder box with magnetic positioning. It aims to solve the problems of inconvenient waste powder box replacement and low stability in fit.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waste powder box with magnetic positioning, comprising a waste powder hopper, a spiral powder pushing rod disposed inside the waste powder hopper, the spiral powder pushing rod passing through one side of the waste powder hopper and connected to a drive head, a magnetic positioning device and several powder box positioning posts disposed on one side of the waste powder hopper, a guide groove disposed on the upper surface of the waste powder hopper, the magnetic positioning device comprising a magnetic iron sheet, a positioning block and several iron sheet positioning posts, the positioning block being adjacent to the magnetic iron sheet, the magnetic iron sheet being provided with several positioning holes corresponding to the several iron sheet positioning posts, the iron sheet positioning posts cooperating with the positioning holes to quickly position the magnetic iron sheet, the magnetic iron sheet being fixedly installed on the waste powder hopper by screws.

[0006] Based on the above, when replacing the waste toner cartridge, the guide groove cooperates with the printing device to guide the drive head and the toner cartridge positioning post to be accurately installed in the corresponding positions on the printing device, improving replacement efficiency. The printing device is equipped with a magnetic groove that cooperates with the magnetic positioning device. The magnetic positioning device and the magnetic groove work together to attract the waste toner cartridge to the printing device, making the installation of the waste toner cartridge more stable. Furthermore, the iron plate positioning post positions the magnetic iron plate, enabling precise and quick installation of the magnetic iron plate into the designated position, preventing misalignment that could lead to incompatibility with the printing device. Simultaneously, the positioning block, in cooperation with the printing device, strengthens the restraint on the waste toner cartridge, improving installation stability.

[0007] Furthermore, the upper end of the waste powder bin is provided with a full powder monitoring hole with a sensing film, and a sensing component is provided above the sensing film.

[0008] Based on the above, when the waste toner hopper is full of waste toner, the sensing film bulges under the pressure of the waste toner, thereby prompting the sensing component to react and achieve timely replacement, thus avoiding toner clogging in the printing equipment.

[0009] Furthermore, a stop block is provided at the end of the guide groove, and the stop block is integrally injection molded with the waste powder bin.

[0010] Based on the above, when the waste toner cartridge is successfully installed on the printing device, the stop block will fit perfectly with the stop slot on the printing device. While assisting in the installation, it can also be used to determine whether the waste toner cartridge has been successfully installed on the printing device by checking whether the stop block fits perfectly with the printing device.

[0011] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0017] like Figures 1 to 4 As shown, a waste toner cartridge with magnetic positioning includes a waste toner compartment 1. A spiral pusher 2 is installed inside the waste toner compartment 1, passing through one side of the waste toner compartment 1 and connecting to a drive head 3. A magnetic positioning device 4 and several toner cartridge positioning posts 5 are also provided on one side of the waste toner compartment 1. A guide groove 6 is provided on the upper surface of the waste toner compartment 1, and a stop block 14 is provided at the end of the guide groove 6. The stop block 14 is integrally injection molded with the waste toner compartment 1. When replacing the waste toner cartridge, the guide groove 6 cooperates with the printing device to guide the drive head 3 and the toner cartridge positioning posts 5 to be accurately installed in the corresponding positions on the printing device, improving replacement efficiency. The printing device is provided with a magnetic groove that cooperates with the magnetic positioning device 4. The magnetic positioning device 4 cooperates with the magnetic groove to attract the waste toner cartridge to the printing device, thereby making the installation of the waste toner cartridge more stable.

[0018] Preferably, the magnetic positioning device 4 includes a magnetic iron sheet 7, a positioning block 8, and several iron sheet positioning posts 9. The positioning block 8 is adjacent to the magnetic iron sheet 7. The magnetic iron sheet 7 is provided with several positioning holes 10 corresponding to the several iron sheet positioning posts 9. The iron sheet positioning posts 9 cooperate with the positioning holes 10 to quickly position the magnetic iron sheet 7. The magnetic iron sheet 7 is fixedly installed on the waste toner container 1 by screws. The iron sheet positioning posts 9 position the magnetic iron sheet 7, which can accurately and quickly install the magnetic iron sheet 7 into the designated position, preventing misalignment that could cause incompatibility with the printing equipment. In addition, the positioning block 8 cooperates with the printing equipment to strengthen the limiting of the waste toner container and improve stability.

[0019] Preferably, the upper end of the waste toner hopper 1 is further provided with a full toner monitoring hole 12 with a sensing film 11, and a sensing component 13 is provided above the sensing film 11. The sensing component 13 includes a sensing rod 15, a sensing block 16, a rotating column 17, and a rotating column slot seat. The sensing block 16 is located at the lower end of the middle part of the sensing rod 15, and the sensing block 16 is arc-shaped and located above the sensing film 11. The rotating column 17 is connected to the tail end of the sensing rod 15. The rotating column slot seat includes a rotating column slot 18 and a rotating column fixing seat 19. The column body of the rotating column 17 is adapted to be installed in the rotating column slot 18, and the end of the rotating column 17 is fixed in the rotating column fixing seat 19. When the waste toner hopper 1 is full of waste toner, the sensing film 11 bulges under the pressure of the waste toner, thereby pushing the sensing component 13 to react, realizing timely replacement and avoiding toner clogging in the printing equipment.

[0020] The specific implementation of this embodiment is as follows: When replacing the waste toner cartridge, the guide groove 6 cooperates with the printing device to guide the drive head 3 and the toner cartridge positioning post 5 to be accurately installed in the corresponding position of the printing device. At the same time, the printing device is provided with a magnetic suction groove that cooperates with the magnetic suction positioning device 4. The magnetic suction positioning device 4 cooperates with the magnetic suction groove to make the waste toner cartridge adsorb onto the printing device, thereby making the installation of the waste toner cartridge more stable.
