The control method of the present application is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present utility model is mainly used to protect mechanical devices, so the present utility model will no longer explain the control method and circuit connection in detail.

[0039] It should be noted that the heating mechanism 3 increases the temperature inside the stirring tank body 4 through the cooperation of the fan 301, the air pipe 302, the heating box 303, the guide plate 304, and the heating tube 305, so that the resin raw material solidified on the inner cavity wall of the stirring tank body 4 due to low temperature melts and becomes fluid again, which is convenient for cleaning by scraping with a scraper.

[0040] The working principle of the above embodiment is:

[0041] (1) Before starting the equipment, sufficient catalyst is added to the inside of the feeding box 108. After the stirring tank body 4 is started, sufficient raw materials are added to the inside of the stirring tank body 4 through the feeding pipe 2. At the same time, the motor 113 is started. The motor 113 drives the rotating shaft 110 to rotate through the output shaft. The rotating shaft 110 rotates while driving the feeding box 108 to rotate counterclockwise. After the feeding box 108 rotates to a certain angle, the catalyst inside slides along the slope into the feeding pipe 109 and falls on the weighing plate 101. After a certain amount of catalyst is accumulated on the weighing plate 101, the pressure sensor 103 detects a certain pressure. When the pressure reaches the set value, the motor 113 starts again to drive the feeding box 108 back to the initial position. At the same time, the motor 113 starts again to drive the feeding box 108 back to the initial position. The electric push rod 106 is started, and the electric push rod 106 drives the connecting plate 105 to move to the right through the output shaft. The connecting plate 105 drives the weighing plate 101 to move to the right together through the support plate 104. The catalyst on the weighing plate 101 is scraped off by the inner wall of the feeding tube 109 and falls into the inside of the stirring tank body 4 through the feeding tube 109. The adding mechanism 1 weighs the weight of the catalyst put into the feeding tube 109 through the cooperation of the weighing plate 101, the reset spring 102, the pressure sensor 103, the support plate 104, the connecting plate 105 and the electric push rod 106, so that the catalyst is put into the inside of the stirring tank body 4 according to the pre-set dosage, which improves the work efficiency and reduces the labor intensity of the staff.

[0042] (2) When the weather is cold, the raw materials attached to the inner wall of the mixing tank body 4 are easily solidified, which makes it impossible for the scraper to scrape it off. At this time, the fan 301 is started, and the fan 301 conveys air to the inside of the heating box 303 through the cooperation of the air supply pipe 302. The air flows downward along the route separated by the guide plate 304, and is successively heated by the heating pipes 305 during the circulation process, thereby increasing the temperature of the air. The high-temperature air enters the inside of the mixing tank body 4, thereby increasing the temperature and adding the raw materials solidified on the closed surface, so that the solidified raw materials melt and can be scraped off by the hanging plate. The heating mechanism 3 increases the temperature inside the mixing tank body 4 through the cooperation of the fan 301, the air supply pipe 302, the heating box 303, the guide plate 304, and the heating pipe 305, so that the resin raw materials solidified on the inner wall of the mixing tank body 4 due to low temperature melt and become fluid again, which is convenient for scraping and cleaning by the scraper.
