Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a plastic particle vibrating screen. Background Art

[0002] Plastic particles refer to granular plastics, which are widely used in fields such as clothing production, construction engineering, and agricultural tools. In particular, recycled plastic particles not only fully improve the recycling rate of plastics, but are also very environmentally friendly. Plastic particles can be enhanced by adding special substances to improve the properties of the plastic particles themselves. For example, plating metals such as chromium and nickel on the surface of ABS plastic particles can improve the durability of ABS plastic and be used to make various handles or shells. When processing plastic particles, a unidirectional vibration method such as horizontal left and right shaking vibration is often used to screen the plastic particles. However, plastic particles under this vibration method usually move more in the horizontal direction and lack a certain vibration in the vertical direction, which makes the vibration screening efficiency of plastic particles low. When vibrating and screening plastic particles, since the screen holes of the vibrating screen are pre-fixed, it is often difficult to clean up the plastic particles in time when they are stuck in the screen holes, causing the plastic particles to pass through the screen holes in time to complete the screening, thereby affecting the screening effect of the plastic particle vibrating screen. Therefore, a plastic particle vibrating screen is needed.

[0003] The existing patent document with technical announcement number CN220719973U provides a plastic particle vibration screening device, which relates to the field of plastic particle production technology, including a screening device body and a servo motor. A lifting column is fixedly installed on the top of the screening device body, and a support plate is fixedly installed on the top of the lifting column. A feeding port is installed inside the support plate. A servo motor is installed inside the screening device body, and a lifting screw is fixedly installed on the output shaft of the servo motor. An internal threaded slider is installed on the surface of the lifting screw. The utility model pours the plastic particles into the interior of the screening frame through the feeding port through the servo motor and the lifting screw, and the rotation of the servo motor can rotate the lifting screw, and the rotation of the lifting screw can make the screening frame rock back and forth, and the up and down rocking of the screening frame can rock the plastic particles poured into the screening frame, thereby completing the screening of the plastic particles. However, the CN220719973U technology cannot effectively improve the cleaning effect of the device during operation, and cannot effectively improve the controllability of the device's material discharge, and cannot improve the efficiency of the device's screening. Therefore, a plastic particle vibrating screen is urgently needed. Utility Model Content
