Example
[0026] Based on the existing problems of uneven raw material delivery and poor screening effect in plastic processing, the present invention provides a preferred embodiment of a raw material feeding device for plastic processing, for example... Figures 1-4 As shown: A raw material feeding device for plastic processing includes a support and fixing plate 1, a screw conveyor 3, and a vibrating screening section 4.

[0035] In this embodiment, the vibrating motor 418 drives the screening. The vibrating motors 418 on both sides are started, causing the vibrating screening box 415 to vibrate at high frequency. The raw material jumps and rolls on the first screening inclined plate 4111 and the second screening inclined plate 4112. The qualified raw material slides down the screen holes on the inclined plate and enters the collection hopper 312 through the discharge block 419 at the bottom.

[0036] Working principle: When in use;
[0037] Step 1: The raw material enters the vibrating screen box 415. The raw material to be processed enters the box through the top of the vibrating screen box 415. The vibrating motor 418 drives the screening. The vibrating motors 418 on both sides start, causing the vibrating screen box 415 to vibrate at high frequency. The raw material jumps and rolls on the first screening inclined plate 4111 and the second screening inclined plate 4112. Particle size screening and impurity discharge: qualified raw material slides down the screen holes on the inclined plate and enters the collection hopper 312 through the discharge block 419 at the bottom. Impurities such as metal particles and debris enter the collection box 417 through the rectangular opening 4113. The rectangular opening baffle 4116 can be adjusted to control whether impurities are discharged. The sliding rod 413 cooperates with the sliding cylinder 412, and the spring 414 buffers and reduces the impact on the support plate 1.
[0038] Step 2: Drive motor 315 starts, and drive motor 315 in motor mounting bracket 314 drives rotating rod 316 to rotate. Conveying spiral blade 319 rotates accordingly. Raw material in collection hopper 312 is pushed by conveying spiral blade 319 and moves along conveying box 311 and conveying pipe 317 towards sealing block 318. Raw material is discharged through conveying discharge hopper 3111 on the outer wall of conveying pipe 317 and enters subsequent processing equipment such as injection molding machine and granulator. Sealing block 318 ensures that the end of conveying pipe 317 is sealed to prevent raw material leakage and overflow.
