Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal and sorting devices, in particular to an impurity removal and sorting device for plastic particles. Background Art

[0002] For the processed plastic particles, the particle size is difficult to determine, and there are impurities mixed in the plastic particles. Therefore, before the actual application of the plastic particles, a linear vibrating screening machine will be used to remove impurities and sort the plastic particles.

[0003] The linear vibrating screening machine is equipped with a screening frame consisting of a frame and a screen to screen the plastic particles. However, some plastic particles will be lost during the vibration screening process.

[0004] The main reason for the above problems is that there are no screening holes on the surface of the frame. Therefore, when plastic particles accumulate on the surface of the frame under the action of vibration, the frame cannot screen the plastic particles, resulting in plastic particles or impurities accumulating on the frame. Over a long period of time, it is easy to cause pollution to the internal environment of the linear vibration screening machine. There is no device to block the frame and the screen, so it is impossible to avoid the accumulation of plastic particles or impurities on the frame. To address the above problems, we propose a plastic particle impurity removal and sorting device. Utility Model Content

The linear vibration screening machine, when in use, feeds plastic particles into the interior of the linear vibration screening machine body 1 through the feeding port 102, and at this time, plastic particles of different particle sizes are accumulated on a group of screening frames 2 located at the uppermost end of the interior of the linear vibration screening machine body 1, and then the vibration motor 301 is turned on to make the linear vibration screening machine body 1 vibrate as a whole, thereby making the plastic particles of different particle sizes on the screening frames 2 vibrate, so that under the action of vibration, the plastic particles of different particle sizes can be sorted, and the impurities mixed in the plastic particles can also be separated from the plastic particles under the action of vibration screening, so as to achieve the purpose of impurity removal, and the plastic particles of different particle sizes are discharged through different discharge hoppers 103.

The frame 201 is used to assist the connection between the screen 202 and the linear vibration screening machine body 1.

[0033] A limiting mechanism is provided at the inner top of the top cover 101. Through the limiting mechanism, the plastic particles on the screen 202 will not accumulate on the frame 201 under the action of vibration, thereby reducing the loss of plastic particles. The limiting mechanism includes a limiting plate 401. One end of the two groups of limiting plates 401 is rotatably connected to the inner top of the top cover 101. The limiting plate 401 is rotatably connected to the inner top of the top cover 101 through a hinge.

One end of the connecting rod 4032 is rotatably connected to the top end face of the fixed seat 4031, and the other end of the connecting rod 4032 is threadedly sleeved on the outer wall of the adjusting screw 402.
