[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The particle screening device for plastic processing is provided with a screening frame component group. At present, a screening machine is often used to screen plastic particles. However, after the existing screening machine is assembled, when the position of the blanking guiding mechanism needs to be adjusted again, it needs to be disassembled again. The guiding mechanism is not easy to adjust and cannot be quickly adjusted according to the position of the blanking collection container. In the corresponding designed screening frame component group, there are multiple sets of screening frame component groups. The multiple sets of screening frame component groups are stacked. The screening mesh plates in each layer of the screening frame component group are replaced and adjusted according to the particle sizes to be screened in each layer. Between the multiple layers of screening frame component groups, the upper mounting ring is connected to the lower mounting ring of the upper layer of the screening frame component group through bolts, and the lower mounting ring is connected to the upper mounting ring of the lower layer of the screening frame component group through bolts. The lower mounting ring in the bottom layer of the screening frame component group is connected to the main frame of the screening machine through bolts. The main frame contacts the ground, and a vibration motor is installed in the main frame. Screening is completed through the vibration of the vibration motor. After the overall screening machine is assembled, when the position of the discharge channel needs to be adjusted according to the position of the collection container, the discharge channel is controlled to rotate. The discharge channel will drive the rotating cylinder to rotate. The rotating cylinder rotates through the upper bearing ring and the lower bearing ring, so that the position of the discharge channel can be adjusted. This overall design can easily adjust the position of the blanking guiding mechanism without re-disassembling the structure of the screening machine, which greatly simplifies the adjustment process and saves time and labor.

[0015] 2. The particle screening device for plastic processing is provided with an anti-falling component group. A guiding mechanism is required to facilitate the fixing of the mouth of the storage sack to ensure that the mouth of the sack will not slip. In the corresponding designed anti-falling component group, after the mouth of the sack is sleeved on the discharge end of the discharge channel, by rotating the two hoop members, then making the ends of the two hoop members away from the vertical shaft contact, and then making the bolt connecting member connected to the two hoop members through threads. At this time, the rubber pads in the two hoop members will clamp the mouth of the sack and the outside of the discharge end of the discharge channel. At this time, the mouth of the sack will be clamped on the discharge port. Due to the clamping of the anti-falling component group, the mouth of the sack will not fall from the discharge end, avoiding the risk of the mouth of the sack slipping during the loading process, thus ensuring the smooth collection of materials.

[0030] Working principle: At present, a screening machine is often used to screen plastic particles. However, after the screening machine of the prior art is assembled, when the position of the feeding guiding mechanism needs to be adjusted again, it needs to be disassembled again. The guiding mechanism is not convenient to adjust and cannot be quickly adjusted according to the position of the feeding and collecting container. In the corresponding designed screening frame component group 01, there are multiple groups of screening frame component groups 01 stacked.

At this time, the mouth of the sack will be clamped on the discharge port. Due to the clamping of the anti-falling component group 02, the mouth of the sack will not fall off from the discharge end, avoiding the risk of the mouth of the sack slipping during the loading process, thus ensuring the smooth collection of materials.
