During the injection molding process of plastic products, nylon plastic particles need to be screened. By screening, nylon plastic particles can be separated according to particle size to ensure that the particle size of the final product is more uniform.

In addition, during the screening process, if the inclination angle is not appropriate, particles of different sizes may be mixed together, thereby reducing the screening quality. Therefore, a nylon plastic particle screening device is proposed to address the above problems. Utility Model Content

[0025] Working principle: The above-mentioned plastic particle screening device still has some problems when in use. Since the first screen plate and the second screen plate are fixed structures, the inclination angle of the screen plate cannot be adjusted. Since the inclination angle is fixed, it may not be possible to accurately control the movement trajectory and residence time of the material on the screen, thereby affecting the screening accuracy, and during the screening process, if the inclination angle is not appropriate, it may cause particles of different sizes to mix together, thereby reducing the screening quality; Therefore, a nylon plastic particle screening device is proposed to address the above problems; when the inclination angle of the second screen plate 16 is adjusted, the second motor 12 is started to rotate the second screw rod 13, and with the cooperation of the second limit rod 18, the second lifting plate 14 drives one end of the second screen plate 16 to move upward, so that the inclination angle of the second screen plate 16 can be adjusted as needed.

This movement helps the fine particles in the material to pass through the sieve holes faster, thereby Improve screening accuracy, the adjustable inclination angle helps to avoid material accumulation on the screen hole, so that the material is more evenly distributed on the screen surface, thereby improving screening efficiency. After the inclination angle of the screen plate is adjusted, when screening, after the material is put into the box 1, the third motor 30 is started to rotate the cam 31. Under the cooperation of the spring 27 and the lifting rod 28, the cam 31 drives the box 1 to shake up and down back and forth, thereby causing the first screen plate 7 and the second screen plate 16 to oscillate accordingly, so that nylon plastic particles can be screened. Under the action of the screen plate 7, large particles of nylon plastic particles are intercepted, and small and medium particles of materials pass through the mesh holes of the first screen plate 7 and fall onto the second screen plate 16. Under the action of the second screen plate 16, medium particles of nylon plastic particles are intercepted, and small particles of materials pass through the mesh holes of the second screen plate 16 and fall to the bottom of the box 1, thereby realizing multi-stage screening operation of nylon plastic particles, ensuring that nylon plastic particles of different particle sizes are accurately separated, ensuring that the particle size of the final product is uniform, and ensuring the processing quality of the product;

[0026] When feeding, the nylon plastic particles to be screened are passed into the cylinder 32 through the feed hopper 36, and the fourth motor 33 is started to make the rotating rod 34 drive the dividing plate 35 to rotate. Through the rotation of the dividing plate 35, the amount of material fed into the box 1 each time can be accurately controlled, avoiding the problem of uneven screening or decreased screening efficiency due to too much or too little material. This quantitative feeding method helps to maintain the continuity and stability of the screening process, thereby improving the overall screening efficiency. Quantitative feeding can reduce the accumulation of material on the screen and reduce the risk of screen clogging.
