[0020] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0021] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0022] like Figures 1 to 5 As shown, a masterbatch mixing and stirring structure includes a mixing bin 1 and a stirring mechanism 2, wherein the mixing bin 1 is provided with the stirring mechanism 2. The upper portion of the mixing bin 1 is cylindrical, and the lower portion is conical. The conical bottom of the mixing bin 1 facilitates the accumulation of materials and improves the stirring effect. The stirring mechanism 2 includes a stirring motor 21 and a rotating shaft 22. The stirring motor 21 is fixedly connected to the bin cover 11 outside the mixing bin 1. The detachable bin cover 11 facilitates the cleaning or maintenance of the components inside the mixing bin 1. A boss 111 is provided on the bin cover 11, and the stirring motor 21 is fixedly connected to the boss 111 via a flange 211. The boss 111 can enhance the deformation resistance of the bin cover 11 and prevent the stirring mechanism 2 from deforming the bin cover 11.

[0023] The rotating shaft 22 is located inside the mixing bin 1, and the upper end is fixedly connected to the output end of the stirring motor 21. The lower part of the rotating shaft 22 is provided with a scraping mechanism corresponding to the inner wall of the upper part of the mixing bin 1, and a spiral blade 221 is provided corresponding to the lower part of the mixing bin 1. The spiral blade 221 is provided with an array of through holes 222. The stirring motor 21 controls the forward and reverse rotation of the rotating shaft 22 so that the spiral blade 221 can achieve the effect of turning over the bottom material or assisting in discharging. The material passing through the through hole 222 can increase the degree of disorder of the material, which is beneficial to improving the stirring effect of the masterbatch. As the rotating shaft 22 rotates, the scraping mechanism scrapes off the residual material on the inner wall of the mixing bin 1, thereby improving the utilization rate of the material and ensuring the stirring effect.

[0024] The scraper mechanism includes a scraper 23, a fixing ring 24, and a connecting rod 241. Removable fixing rings 24 are provided at both ends of the rotating shaft 22, corresponding to the scraper 23. The ends of the scraper 23 are fixedly connected to the fixing ring 24 via the connecting rod 241. The removable scraper mechanism facilitates maintenance or replacement. The scraper 23 rotates with the rotating shaft 22 and scrapes material from the inner wall of the mixing bin 1. A plurality of evenly spaced balls 233 are provided on the side of the scraper 23 near the mixing bin 1. The balls 233 allow the scraper 23 to roll against the inner wall of the mixing bin 1, reducing friction between the scraper 23 and the mixing bin 1. Slanted surfaces 231 are provided on both sides of the scraper 23, with multiple ridges 232 extending along the length of the inclined surfaces 231. The scraper 23 scrapes material via the inclined surfaces 231, and the ridges 232 prevent material from re-adhering to the inclined surfaces 231.

[0025] A plurality of support legs 13 are provided on the circumference of the mixing bin 1, and the mixing bin 1 is kept in a stable state by the support legs 13. A plurality of silos 3 are provided on the circumference of the mixing bin 1, and a vertical pipe 31 is provided at the bottom of the silo 3. The mixing bin 1 is provided with a feed pipe 14 connected to the vertical pipe 31, and a feeding mechanism is provided in the feed pipe 14. The feeding mechanism includes a feeding motor 33 and a screw rod 331; one end of the feed pipe 14 is connected to the mixing bin 1, and the other end is fixedly connected to the feeding motor 33, and the upper part is connected to the vertical pipe 31. A screw rod 331 is provided in the feed pipe 14, and one end of the screw rod 331 is fixedly connected to the output end of the feeding motor 33. The material is temporarily stored in the silo 3, and the material enters the feed pipe 14 along the vertical pipe 31 and is fed into the mixing bin 1 along the feed pipe 14 under the action of the feeding mechanism. An air duct 34 is provided on the silo 3. The side of the air duct 34 close to the silo 3 is connected to the mixing silo 1 through multiple air holes 341 distributed in an array, and a hot air blower 342 is provided on the other side. The top of the silo 3 is provided with a freely openable top cover 32, which is provided with multiple air vents. The hot air blower 342 blows hot air towards the material in the silo 3, so that the moist gas in the silo 3 is discharged from the air vents of the top cover 32, thereby maintaining a certain degree of dryness of the material and preventing the material from sticking to the inner wall of the equipment. A discharge pipe 12 is provided at the bottom end of the mixing silo 1, and an insert plate 121 is provided on the cross section of the discharge pipe 12. The discharge flow rate of the mixing silo 1 is controlled by controlling the depth of the insert plate 121 inserted into the discharge pipe 12.

[0026] The working principle of this embodiment of the utility model is as follows: the material is initially dried in the silo 3 and then enters the mixing silo 1 under the action of the feeding mechanism. The stirring motor 21 drives the rotating shaft 22 to rotate, and the spiral blade 221 rotates with the rotating shaft 22 to stir the material in the mixing silo 1; the scraper 23 rotates with the rotating shaft 22 and scrapes the material on the inner wall of the mixing silo 1.
