Liquid leakage, the drop pipe 16 is located inside the limiting groove 15, and a throttle hole 14 is provided on the rotating disk 13 to control the falling of plastic melts of different viscosities. The throttle hole 14 is located inside the limiting groove 15, and the apertures of the throttle hole 14 are different. The lower bottom wall of the protection box 1 is fixedly connected with the drop pipe 16 to prevent the melt from directly entering the limiting groove 15 and causing leakage. The lower surface of the protection box 1 is provided with a drop port 19 for connecting to the insulation tank 8. The lower end of the drop port 19 is fixedly connected to the insulation tank 8 for storing the plastic melt to avoid cooling before transportation. The right surface of the insulation tank 8 is fixedly connected with a booster pump 18 for generating transportation pressure.
[0024] The lower surface of the protection box 1 is fixedly connected with a support block 6 for supporting the protection box 1. The lower surface of the protection box 1 is fixedly connected with a support rod 7 for supporting the protection box 1. The lower surfaces of the support block 6 and the support rod 7 are fixedly connected with a bottom plate 9 for carrying various accessories. The insulation tank 8 and the booster pump 18 are both located on the upper surface of the bottom plate 9. The upper surface of the protection box 1 is movably connected with an upper cover 2 for supporting the main motor 3. The upper surface of the upper cover 2 is fixedly connected with the main motor 3 for driving the stirring shaft 10 to rotate. The output end of the main motor 3 is fixedly connected with the stirring shaft 10. Used to drive the stirring plate 11 to rotate, the stirring shaft 10 passes through the upper cover 2 and extends to the inside of the protective box 1, the side surface of the stirring shaft 10 is fixedly connected with the stirring plate 11, which is used to heat the material evenly and avoid sticking to the inner wall, the stirring plate 11 is provided with holes to enhance the heating effect, the lower bottom wall of the protective box 1 is provided with limiting holes to avoid the deviation of the stirring shaft 10, the lower end of the stirring shaft 10 is located inside the stirring shaft 10, the front surface of the protective box 1 is fixedly connected with the feeding pipe 4 for the entry of plastic particles, and the feeding pipe 4 is connected with the protective box 1.
[0025] Working principle: First, the plastic particles to be melted are fed into the protective box 1 through the feed pipe 4, while ensuring that the throttling holes 14 on the rotating disk 13 do not correspond to the drop tube 16 to prevent the plastic particles from falling directly. Then, the heater 5 is started, which generates heat and conducts the heat to the inside of the cavity 17 through the heat pipe 12 to heat and melt the plastic particles. During the melting process of the plastic particles, the main motor 3 is started, which drives the stirring shaft 10 to rotate, and then drives the stirring plate 11 to rotate and stir inside the protective box 1. Since the stirring plate 11 is provided with holes, this helps to evenly mix and melt the plastic particles and reduce the possibility of sticking to the inner wall. The auxiliary motor 20 drives the rotating disk 13 to rotate, so that the throttling holes 14 with different apertures on the rotating disk 13 and the drop tube 16 are aligned. Corresponding to the drop pipe 16, the melted plastic liquid will flow out through the drop pipe 16 and the corresponding throttling hole 14. Since the apertures of the throttling hole 14 are different, the appropriate aperture can be selected according to the viscosity of the plastic liquid to control the flow rate and avoid splashing or bubbles caused by too fast flow or poor flow, as well as blockage of the falling channel. The melted plastic liquid flows into the insulation tank 8 through the drop port 19. The insulation tank 8 can maintain the temperature of the plastic liquid to prevent it from cooling too quickly. At the same time, the booster pump 18 can pressurize the plastic liquid in the insulation tank 8 for subsequent transportation to other process links. During the entire melting process, the sealing of the protective box 1 is ensured by the upper cover 2, the support block 6 and the support rod 7 provide stable support, and the bottom plate 9 serves as the base of the entire equipment to carry various components.
