Problems solved by technology

[0004] 1. The plastic granule manufacturing machine performs mixing, kneading, and conveying processes through the twin-shaft extruder 3. In view of the length-to-diameter ratio of the conventional twin-shaft extruder 3, which is about 77 cm in diameter, the twin-shaft extruder 3 has a diameter of about 77 cm. The length of the shaft extruder 3 is about 4 m, and the viscosity of the thermoplastic polyurethane resin is about 100,000 cps. Therefore, the motor of the biaxial extruder 3 needs to output a high torque of at least 200 horsepower, and has a power of more than 150 kilowatts. The shortcomings of high power and high power consumption. In addition, in view of the different reaction levels of raw materials, the viscosity of thermoplastic polyurethane resins is also different. Therefore, the energy waste of the twin-screw extruder 3 is caused, which is not environmentally friendly. In addition, If the user increases the rotational speed of the twin-screw extruder 3 in order to increase the output, the thermoplastic polyurethane resin will be output before it has fully reacted, resulting in defective products, which also makes it difficult for the plastic pellet manufacturing machine in terms of output and quality. Taking into account, very environmentally friendly

[0005] 2. The output port of the quantitative mixer 2 will often be blocked by material accumulation, which will increase the pressure in the quantitative mixer 2, which will easily lead to accidents such as pipe bursts, and further make the finished product defective

[0006] 3. To manufacture various plastic pellets, parameters must be adjusted according to the physical requirements of the product. However, the plastic pellet manufacturing machine adopts a continuous process. Therefore, each continuous process must be completed for each parameter during the test process. Therefore, repeat The continuous process will greatly increase the waste of energy and resources
