[0023] 2. The efficient multi-particle plastic powder separation device and use method, through the setting of the surround arm, when the separation component drives it to rotate, the surround arm will fit against the outer wall of the pretreatment component and rotate, thereby driving the contact block to rotate, and after driving the contact block to move to the adapter groove, the contact block can be bounced into the inner cavity of the adapter groove by the set second spring, and when the contact block is driven out of the adapter groove, the pretreatment component can be driven to vibrate, and after vibration, the multi-particle plastic powder raw materials that fall into the inner cavity of the pretreatment component can be separated and processed in conjunction with the set screen, so that a large volume of multi-particle plastic powder raw materials can remain in its inner cavity, and at the same time, through the set first spring, after the pretreatment component vibrates, it will drive it to contact with the positioning block, thereby increasing the amplitude of the vibration of the pretreatment component, thereby improving the accuracy of separation of the multi-particle plastic powder raw materials.

[0024] 3. The efficient multi-particle plastic powder separation device and use method can drive the separation component and the main gear to rotate by starting the set servo motor. After the separation component rotates, the set filter screen can be used to throw the powdered material into the inner cavity of the device body. When the main gear rotates, it will drive the main crushing roller to rotate and mesh with the sub-gear, thereby driving the sub-crushing roller to rotate. The main crushing roller and the sub-crushing roller can crush the remaining multi-particle plastic powder raw materials in the inner cavity of the separation component, thereby improving the utilization rate of the multi-particle plastic powder raw materials and achieving a better separation effect.

After being squeezed, the first spring (16) will be reset, thereby increasing the vibration amplitude of the pre-processing component (12). At this time, the powdery material contained in the multi-granular plastic powder raw material can pass through the screen (13) and fall into the inner cavity of the separation component (18), and the remaining large volume of the multi-granular plastic powder raw material can remain in the inner cavity of the pre-processing component (12); S3: When the main gear (25) rotates, it meshes with the sub-gear (27), so that the main gear (25) drives the main crushing roller (23) to rotate and drives the sub-crushing roller (24) to rotate at the same time, so that the main crushing roller (23) and the sub-crushing roller (24) can crush the multi-particle plastic powder raw material entering the inner cavity of the separation component (18), so as to improve the separation effect of the multi-particle plastic powder raw material. When the separation component (18) rotates, the powdery material can be thrown into the inner cavity of the device body (1) through the filter screen (19) by centrifugal force; S4: When the secondary gear (27) rotates, the belt (28) and the pulley (29) are started, and one of the pulleys (29) drives the second fan blade (30) in its inner cavity to rotate, so that the powder material in the inner cavity of the device body (1) is drawn out of the inner cavity of the device body (1) through the discharge pipe (31), and the powder material can be received and processed in conjunction with the receiving box (11), thereby completing the separation of multi-particle plastic powder raw materials.
