[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 One embodiment provided by this utility model: A mixing device for producing erasers. The mixing motor 2, the auger conveyor cylinder 14 and the mounting motor 17 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. The device includes a mixing cylinder 1, a mixing component installed inside the mixing cylinder 1, a mixing motor 2 installed on the top surface of the mixing cylinder 1, a feeding cylinder 3 installed on the upper surface of the mixing cylinder 1, a dispersing component provided on the top surface of the inner wall of the mixing cylinder 1, and a feeding component installed at the lower end of the mixing cylinder 1. The stirring assembly includes a rotating shaft 4, and the outer surface of the rotating shaft 4 is provided with a first stirring blade 5 and a second stirring blade 6; The dispersing assembly includes a connecting column 11, with a trapezoidal ring 20 installed at the lower end of the connecting column 11. A first stirring blade 5 and a second stirring blade 6 are sequentially installed on the left and right sides of the rotating shaft 4. An inclined plate 7 is installed on the top surface of both the first stirring blade 5 and the second stirring blade 6. An inclined groove 8 is formed inside the inclined plate 7, and a guide block 9 is installed on the outer surface of the inclined plate 7. Two stirring rollers 10 are fixedly connected to the lower surfaces of both the first stirring blade 5 and the second stirring blade 6. In use, the feed cylinder 3 is first used to feed the material, which then enters the mixing drum 1 through the feed cylinder 3. The stirring motor 2 is then started, driving the rotating shaft 4 to rotate. The rotating shaft 4 then drives the first stirring blade 5 and the second stirring blade 6 to rotate. The inclined plate 7 and the inclined groove 8 guide and convey the rotating material, which is conveyed from inside the inclined groove 8. The guide block 9 also guides and conveys the material.

[0019] The connecting column 11 is installed on the top surface of the inner wall of the mixing drum 1, and the trapezoidal ring 20 is fixedly connected to the connecting column 11. The mixing roller 10 is set to stir during the stirring process following the rotating shaft 4. When the feeding cylinder 3 feeds material, the material is fed onto the outer surface of the trapezoidal ring 20, and then the trapezoidal ring 20 can guide and convey the material evenly, thereby avoiding the accumulation of material in one place. This setting, through the cooperation of the stirring component and the dispersing component, can guide and stir the material inside the mixing drum 1 at the same time as dispersing and feeding, so that the material inside the mixing drum 1 is stirred more evenly.

[0020] The feeding assembly includes a feeding pipe 12, which is installed on the lower surface of the mixing drum 1. An acceleration pipe 13 is installed at the lower end of the feeding pipe 12, and a support plate 16 is installed on the upper surface of the acceleration pipe 13. A motor 17 is installed on the back of the support plate 16, and a rotating column 18 is installed through the interior of the support plate 16 at the output end of the motor 17. A contact block 19 is installed on the outer surface of the rotating column 18. A auger conveyor cylinder 14 is installed at the lower end of the acceleration pipe 13, and a discharge pipe 15 is installed at the lower end of the auger conveyor cylinder 14. A drive motor is installed on the right side of the auger conveyor cylinder 14. When the mixing drum 1 begins to discharge material, the material will flow from the inside of the feeding pipe 12 and then continue to flow through the acceleration pipe 13. At this time, the size of the acceleration pipe 13 is larger than that of the feeding pipe 12, thereby accelerating the feeding speed. Simultaneously, the mounting motor 17 is started, and the forward and reverse rotation of the mounting motor 17 drives the rotating column 18 and the contact block 19 to rotate synchronously. At this time, the contact block 19 will abut against the outer surface of the feeding pipe 12, which can prevent the material inside the feeding pipe 12 from blocking and accelerate the feeding of the material. Then the material flows into the inside of the auger conveyor drum 14. At this time, the drive motor drives the auger conveyor drum 14 to transport the material inside, so that the material can be evenly discharged through the discharge pipe 15. This setting can make the material discharge speed faster and avoid blockage during the feeding process through the feeding component.

[0021] Working principle: When using this device, the operator first connects it to an external power source to provide power. Then, the feed cylinder 3 is filled with material, which enters the mixing drum 1 through the feed cylinder 3. The mixing motor 2 is then started, driving the rotating shaft 4 to rotate. The rotating shaft 4 then drives the first mixing blade 5 and the second mixing blade 6 to rotate. The inclined plate 7 and the inclined chute 8 guide and convey the rotating material, which is then conveyed from inside the inclined chute 8. The guide block 9 also guides and conveys the material. Simultaneously, the mixing roller 10 stirs the material as it follows the rotating shaft 4. When the feed cylinder 3 is filled with material, it is fed onto the outer surface of the trapezoidal ring 20, which then guides and conveys the material evenly, preventing material from accumulating in one place. When the mixing drum 1 begins to discharge material, the material will flow from the inside of the feeding pipe 12 and then continue to flow through the acceleration pipe 13. At this time, the size of the acceleration pipe 13 is larger than that of the feeding pipe 12, thereby accelerating the feeding speed. Simultaneously, the installation motor 17 is started. The forward and reverse rotation of the installation motor 17 drives the rotating column 18 and the contact block 19 to rotate synchronously. At this time, the contact block 19 will abut against the outer surface of the feeding pipe 12, which can prevent the material inside the feeding pipe 12 from blocking the material and accelerate the feeding of the material. Then the material flows into the inside of the auger conveyor drum 14. At this time, the drive motor drives the auger conveyor drum 14 to transport the material inside, so that the material can be evenly discharged through the discharge pipe 15. The above is the working principle of this utility model.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
