[0025] This utility model provides, for example Figures 1-4 The automatic oil weighing and feeding integrated control system for plastic production shown includes a mixing tank 2 mounted on a base frame 1. The mixing tank 2 includes a tank body and a tank cover. A rotating shaft 8 is rotatably mounted on the tank cover. A connecting sleeve 6 is fixedly connected to the top of the tank cover. The connecting sleeve 6 surrounds the outside of the rotating shaft 8. A motor 5 is fixedly connected to the top of the connecting sleeve 6. The rotating shaft 8 is fixedly connected to the drive shaft of the motor 5. The motor 5 drives the rotating shaft 8 to rotate.

[0026] A column 3 is fixedly connected to the base frame 1, and a slide block 4 is slidably mounted on the column 3. The motor 5 is fixedly connected to the slide block 4. In actual use, an electric cylinder is installed on the column 3 to drive the motor 5, the rotating shaft 8, and the barrel cover to move up and down through the slide block 4, so as to facilitate the addition of crushed material into the barrel.

[0027] The top of the mixing tank 2 is equipped with a weighing hopper 7, which is filled with white oil and equipped with weighing equipment, including a weight sensor and a solenoid valve, to achieve automatic weighing of the white oil, integrating oil weighing, mixing and feeding into one unit.

[0028] A square tube 14 is fixedly connected to the outer wall of the rotating shaft 8. The square tube 14 is inclined, and the end away from the rotating shaft 8 is inclined downward. A telescopic rod 15 is slidably arranged inside the square tube 14. A scraper 16 is fixedly connected to the end of the telescopic rod 15 away from the square tube 14. The scraper 16 is L-shaped and can simultaneously scrape and clean the bottom and side walls of the mixing tank 2. A rotating sleeve 10 is arranged above the mixing tank 2. The rotating sleeve 10 surrounds the outside of the rotating shaft 8. An air hole is opened on the rotating shaft 8. The rotating sleeve 10 is always connected to the inner cavity 9 through the air hole. An inner cavity 9 is opened inside the rotating shaft 8. The rotating sleeve 10 is connected to the square tube 14 through the inner cavity 9.

[0029] A control assembly for cooperating with the rotating sleeve 10 and performing air extraction and suction is provided above the mixing tank 2. The control assembly includes a cylinder 11, which is fixedly connected to the top of the mixing tank 2 and to the outer wall of the rotating sleeve 10. The cylinder 11 communicates with the rotating sleeve 10. A piston block 12 is slidably arranged inside the cylinder 11. An electric push rod 13 is fixedly connected to the cylinder 11, and the piston block 12 is fixedly connected to the telescopic end of the electric push rod 13.

[0030] During the stirring operation, the telescopic end of the electric push rod 13 is retracted, causing the piston block 12 to move away from the rotating shaft 8. This draws gas from the inside of the square cylinder 14 through the inner cavity 9, causing the telescopic rod 15 to retract and the scraper 16 to not contact the inner wall of the mixing tank 2, thus reducing wear during the stirring process. The motor 5 drives the rotating shaft 8 to rotate, and the scraper 16 and other structures are used for mixing.

[0031] Furthermore, the bottom of the mixing tank 2 is equipped with a discharge pipe (not shown in the figure) for feeding material to the granulation equipment after mixing.

[0032] During cleaning, the telescopic end of the control electric push rod 13 extends, driving the piston block 12 to move towards the rotating shaft 8, and conveying gas into the inside of the square cylinder 14 through the inner cavity 9, causing the telescopic rod 15 to extend, the scraper 16 to adhere to the inner wall of the mixing tank 2, and the motor 5 drives the rotating shaft 8 to rotate, while simultaneously scraping and cleaning the bottom and side walls of the mixing tank 2.

[0033] To improve the stability of the scraper 16 during use, a sliding channel 17 is provided at the bottom of the rotating shaft 8 for the scraper 16 to slide. The scraper 16 slides inside the sliding channel 17, thereby improving the stability of use.
