Description

Technical Field

[0001] The utility model relates to the field of vibrating screening machines, in particular to a vibrating screening machine for producing modified PC plastic particles. Background Art

[0002] The vibrating screening machine works by utilizing the reciprocating vibration generated by the excitation of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar gyratory vibration, while the lower rotating weight causes the screen surface to produce conical gyratory vibration. The combined effect causes the screen surface to produce compound gyratory vibration. The vibrating screening machine is mainly composed of a screen box, an exciter, a suspension (or support) device and an electric motor. The electric motor drives the exciter main shaft to rotate through a V-belt. Due to the centrifugal inertia force of the unbalanced weight on the exciter, the screen box vibrates. By changing the eccentric weight of the exciter, different amplitudes can be obtained.

[0003] In the prior art, modified PC plastic granules are often produced and processed using a vibrating screening machine to screen and process the materials. However, in actual use, the existing vibrating screening machine requires not only the replacement of the screen when the material needs to be screened, but also the replacement of the screen when the screen is damaged after long-term use or when the screen needs to be cleaned. However, when replacing the screen, it is necessary to open the sealing cover from the frame and then use auxiliary tools to remove the screen installed on the inner frame of the screen box by bolts. As a result, each time the screen is disassembled, the sealing cover needs to be removed first and then multiple bolts need to be removed, which is not convenient for quick disassembly and replacement of the screen and also brings inconvenience to the subsequent installation operation of the screen, which not only affects the production efficiency but also causes inconvenience to the disassembly and assembly of the screen.
