[0002] Toner is a powdered substance used for pigments or laser printing. Toner raw materials can be obtained by crushing them. During production, the toner raw materials need to be added to the air flow mill so that the toner raw materials can be fully crushed in the air flow mill. When adding raw materials to the air flow mill, the raw materials are usually directly added to the air flow mill through a dosing device. The dosing device consists of a connecting pipe and a closing cover that can close the connecting pipe. It has a simple structure and can quickly feed the toner raw materials into the air flow mill, making it easy to use.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing dosing device adds carbon powder raw materials, it is necessary to use a carbon powder raw material measuring device to determine the volume and weight of the added carbon powder before adding. There are many pre-steps and it is inconvenient to use, resulting in low adding efficiency. At the same time, it requires a high level of experience from the adding operator. Utility Model Content

[0015] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0016] See Figure 1As shown, the technical solution adopted in this specific embodiment is: a quantitative dosing device for carbon powder processing raw materials, including a dosing tube 1 and an inclined conveying tube 2 arranged on the bottom side wall of the dosing tube 1 and connected to the dosing tube 1, a closure cover 4 is movably engaged with the top of the dosing tube 1, and a quantitative dosing device 6 is provided in the dosing tube 1, and the quantitative dosing device 6 includes an inner core 61 fixedly arranged on the inner wall of the dosing tube 1, and a left arc-shaped plate 63 is provided on the outer side of the inner core 61 with an outer wall that is in contact with the inner wall of the dosing tube 1 and is slidably connected. A right curved plate 62 is provided on the other side of the outer wall of the addition tube 1 and is slidably connected. A connecting bracket 67 is provided between the inner wall of the left curved plate 63 and the right curved plate 62 and the outer wall of the inner core 61, and an addition port 64 is formed between the bottom of the left curved plate 63 and the right curved plate 62. The carbon powder raw material is put into the quantitative addition device 6 and filled with it for single quantitative addition. When in use, the bottom end of the inclined conveying tube 2 is connected to the side wall of the air flow mill. When the carbon powder raw material needs to be added, it is opened. Open the closing cover 4, and the carbon powder raw material can be fed into the inclined conveying pipe 2 through the adding pipe 1 and introduced into the air flow mill for adding carbon powder raw material. When adding carbon powder raw material, first pull the left curved plate 63 and the right curved plate 62 apart to make them slide along the inner wall of the adding pipe 1 under the restriction of the inner core 61 and the connecting bracket 67, and then close the adding port 64 at the bottom of the two and open the top of the two. Then, the carbon powder raw material can be added into the left curved plate 63 and the right curved plate 62 through the openings at the top of the two. The carbon powder is continuously added between the formed cavities until they are full, and then the left arc plate 63 and the right arc plate 62 can be pulled in the opposite direction to reclose the top of the left arc plate 63 and the right arc plate 62, and the bottom adding port 64 is opened. At this time, the carbon powder raw material in the cavity formed by the left arc plate 63 and the right arc plate 62 can be added and sent into the inclined conveying pipe 2. Each time, the carbon powder is quantitatively added to the volume of the cavity. There is no need to use a measuring device to measure before adding. There are fewer pre-steps, quantitative addition is convenient, and the operating experience requirement is low.

[0017] An expansion platform plate 3 is also provided between the top end of the adding tube 1 and the closing cover 4, which is conducive to placing the carbon powder raw material container on the expansion platform plate 3 when adding, eliminating the need to run up and down to take the material, making the adding process smoother;

[0018] The bottom of the inner wall of the adding pipe 1 is provided with an arc block 5 for guiding the carbon powder raw material, which is conducive to guiding the falling carbon powder raw material through the arc surface of the arc block 5 so that it can fully enter the inclined conveying pipe 2 to avoid residue;

[0019] A reset spring 65 is provided between the outer wall of the top of the left curved plate 63 and the right curved plate 62 and the inner wall of the adding pipe 1. After the left curved plate 63 and the right curved plate 62 are pulled apart, they can be released and the elastic force of the reset spring 65 can be used to restore them to their original state without the need to pull them back in the opposite direction, making it easier and more convenient to use.

[0020] The tops of the left curved plate 63 and the right curved plate 62 are both provided with handles 66 , which are helpful for the user to better transmit the force of the hand through the handles 66 , thereby making it easier to pull the plates apart.

[0021] Working principle of the present invention: When the present invention is used, the bottom end of the inclined conveying pipe 2 is connected to the side wall of the airflow mill. When it is necessary to add carbon powder raw materials, the closing cover 4 is opened, and the carbon powder raw materials can be fed into the inclined conveying pipe 2 through the adding pipe 1 and introduced into the airflow mill for adding carbon powder raw materials. When adding carbon powder raw materials, first pull the left arc plate 63 and the right arc plate 62 apart to both sides, so that the two slide along the inner wall of the adding pipe 1 and under the restriction of the inner core 61 and the connecting bracket 67, and then close the adding ports 64 at the bottom of the two and open the tops of the two, and then the carbon powder raw materials can be added. Add carbon powder into the cavity formed by the left arc plate 63 and the right arc plate 62 through the openings at the top of the two, continue adding to fill it up, and then pull the left arc plate 63 and the right arc plate 62 in the opposite direction to reclose the top of the left arc plate 63 and the right arc plate 62, and open the bottom adding port 64. At this time, the carbon powder raw material in the cavity formed by the left arc plate 63 and the right arc plate 62 can be added and sent into the inclined conveying pipe 2. Each time, a quantitative amount of carbon powder is added to the volume of the cavity. There is no need to use a measuring device to measure before adding. There are few pre-steps, quantitative addition is convenient, and low operating experience is required.
