Before kneading the toners, they need to go through multiple stirring and mixing processes. However, when multiple toners are mixed simultaneously, it is easy to have uneven melting during the kneading process due to different specifications and sizes and the lack of pre - heating treatment after mixing, which will affect the quality of the products. Therefore, the existing kneading machines cannot pre - heat the toners before kneading, and it is easy to have the problem of insufficient melting. Summary of the Utility Model

[0023] The following will be combined with the drawings and embodiments to detail the implementation manner of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Figures 1 - 3 This is an embodiment of the present utility model. When producing products of different colors, the multi - mixing process of color powder becomes one of the key conditions for the product. Before the color powder is kneaded, it needs to go through multiple stirring and mixing processes. However, when multiple color powders are mixed simultaneously, it is easy to have uneven melting during the kneading process due to different specifications and sizes and the lack of pre - heating treatment after mixing, which will affect the quality of the product. Therefore, the existing kneading machines cannot pre - heat the color powder before kneading the color powder, and it is easy to have the problem of insufficient melting. Based on the above existing problems, the inventor elaborates a color powder pre - heating and kneading device, which first uniformly pre - heats the color powder when the color powder initially enters the kneading bin 1. During the pre - heating process, the laying plate 25 is used to spread the color powder placed on the material passing plate 21, avoiding the problem of poor pre - heating effect caused by the stacking of color powder when it enters from the feeding port 4, enhancing the uniform heating of the color powder on the material passing plate 21, and the laying plate 25 can make the agglomerated color powder disperse, facilitating the subsequent mixing operation after the pre - heating of the color powder and increasing the processing effect of the color powder.

[0026] A toner preheating and kneading device described in this solution is specifically provided with a kneading bin 1. Inside the kneading bin 1, there is a preheating member 2 and a mixing member 3 arranged at the lower end of the preheating member 2. An inlet 4 is opened on the kneading bin 1, and the inlet 4 establishes an introduction channel for toner particles to the preheating member 2. An outlet 5 is opened on the kneading bin 1 at the lower end of the mixing member 3. The outlet 5 is eccentrically opened on the bottom plate of the kneading bin 1, and the structure of the kneading bin 1 at the opening position of the outlet 5 is arranged to be rotatable.

[0027] The preheating member 2 includes a material passing plate 21. A number of overflow holes 22 are opened on the material passing plate 21. A heating pipe 23 is installed inside the material passing plate 21. A central shaft 24 is installed at the center position of the material passing plate 21. A laying plate 25 is installed on the central shaft 24. The laying plate 25 can cause the agglomerated toner to be in a dispersed state. The laying plate 25 rotates synchronously with the central shaft 24. The inlet 4 is eccentrically opened on the kneading bin 1. A driving motor is installed on the top plate 36 of the kneading bin 1. The driving motor is coaxially connected to the central shaft 24. The controller controls the opening and closing time of the driving motor. The material passing plate 21 is connected to the central shaft 24 through a rolling bearing.

[0028] The mixing component 3 includes a backing plate 31 disposed at the upper end of the discharging opening. A notch 32 adapted to the discharging opening 5 is formed in the backing plate 31, and the size of the notch 32 is smaller than that of the discharging opening 5. A mixing plate 33 is installed at the upper end of the backing plate 31. A material passing channel 35 opposite to a plurality of mixing openings 34 is arranged at the upper end of the mixing plate 33. A top plate 36 is installed at the upper end of the material passing channel 35. A central shaft 310 is installed at the central position on the top plate 36. The central shaft 310 rotates synchronously with the central shaft 24. A feeding opening 37 adapted to the size of the mixing opening 34 is formed in the top plate 36. A plurality of mixing openings 34 are formed in the mixing plate 33, and the side walls of the mixing openings 34 are all cut into rounded corners. There is a gap between the mixing plate 33 and the backing plate 31. A ring plate 39 is installed on the bottom surface of the top plate 36. A ring groove adapted to the ring plate 39 is formed in the backing plate 31, and the height of the ring plate 39 is greater than the depth of the ring groove. A leveling brush 312 is installed on the side wall of the mixing opening 34 of the mixing plate 33, and the length of the leveling brush 312 extending towards the backing plate 31 is less than the height of the ring plate 39 protruding from the ring groove. When the driving electric appliance starts to rotate under the drive of the controller, first, the laying plate 25 rotates on the material passing tray 21 to level the material. At the same time, the whole mixing component 3 rotates except for the backing plate 31, and the toner gradually moves from the top plate 36 to the mixing plate 33 through the material passing channel 35 and finally drops onto the backing plate 31 through the mixing opening 34. However, due to the thickness of the toner, the distance between the backing plate 31 and the mixing plate 33 will become saturated. After that, the toner will accumulate on the mixing plate 33 and enter or overflow from the mixing opening 34 as the mixing plate 33 rotates. Thus, the side wall of the mixing opening 34 will produce a scraping effect on the toner, thereby achieving color mixing between different types of toner and finally achieving preheating and mixing operations before the mixing process. When discharging is required after a preset time, the position of the discharging opening 5 is manually adjusted so that the position of the discharging opening 5 is adapted to the position of the notch 32, thereby achieving the discharging purpose.

[0029] Scrapers 38 are installed between adjacent feeding openings 37 on the top plate 36. The scrapers 38 are arranged on the top plate 36 in a conical shape. They connect two feeding openings 37. The inclined surface of the scraper 38 extends towards the feeding opening 37 and is connected to the side wall of the feeding opening 37. Installing the scraper 38 at the lower end of the material passing tray 21 can evenly disperse the toner falling from the material passing tray 21 on the top plate 36. At the same time, the inclined surface of the scraper 38 extends towards the feeding opening 37 and is connected to the side wall of the feeding opening 37. Thus, the toner falling from the material passing plate is dispersed by the scraper 38 and guided along the inclined surface of the scraper 38 into the feeding opening 37. Thereby, the toner is dispersed along the material passing channel 35 onto the mixing plate 33, enhancing the uniformity of the toner amount in a plurality of mixing openings 34 on the mixing plate 33.

The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common general knowledge in the art. Moreover, the present utility model is mainly used to protect mechanical devices. Therefore, the control mode and circuit connection of the present utility model will not be explained in detail.
