Abstract
Description
Technical Field
[0001] This utility model relates to an impurity separation system for plastic particles. Background Technology
[0002] Plastic granules are the basic raw material of the plastics industry. Their diversity and wide range of uses make them an indispensable material in modern production. The production process of plastic granules mainly includes four core stages: pretreatment (sorting, crushing, and washing), extrusion granulation, cooling and pelletizing, and packaging. During the production process, impurities inevitably get mixed into the plastic granules. The impurities in plastic granules mainly include metal shavings, dust, and other high-melting-point polymers. These impurities will cause a series of problems during injection molding, so they must be removed.
[0003] The existing process for removing impurities from plastic granules must be carried out sequentially in different devices, which is quite cumbersome. Because the plastic granules must be fed and discharged multiple times between devices, the processing speed is slow, which is both time-consuming and labor-intensive. In addition, the purchase of different devices requires a lot of money, resulting in high processing costs. Furthermore, the placement of different devices occupies a lot of space, resulting in low space utilization. Further improvements are needed. Utility Model Content

[0031] The material distribution assembly 62 also includes a first discharge hopper 628 fixed to the bottom of the top frame 2 and located below the first guide hopper 622, with the bottom opening of the first guide hopper 622 connected to the top opening of the first discharge hopper 628.

[0034] The material distribution assembly 62 also includes a detachable baffle 627 that is fixed between the two side plates 625 and surrounds the material distribution roller 624.
[0035] A plastic granule impurity separation system further includes a Y-shaped distributor 8 fixed upside down on the top of the top frame 2 and a feed hopper 4 located above the Y-shaped distributor 8. The two discharge ports of the Y-shaped distributor 8 are respectively located above the top opening of the discharge hopper 3, and the bottom opening of the feed hopper 4 is connected to the feed port of the Y-shaped distributor 8.
[0036] Working principle:
[0037] Plastic granules are added to the feed hopper 4 and then fall into the discharge hopper 3 through the two openings of the Y-shaped distributor 8. Under the action of the two guide troughs 53 in the diversion mechanism 5, the plastic granules are divided into two batches. At the same time, each first vibration motor 54 needs to be activated to ensure the continuous movement of the plastic granules. Each batch of plastic granules slides down the guide trough 53 into the deceleration groove 612 in the deceleration assembly 61 of the screening mechanism 6 on the same side. During this process, the extension and retraction ends of the two electric cylinders 71 in the control valve 7 can be driven to extend outward or inward as needed to move the valve plate 72 closer to or away from the deceleration groove 612, thereby reducing or increasing the gap between the valve plate 72 and the deceleration groove 612, thus regulating the flow rate of the plastic granules sliding down onto the deceleration groove 612. At the same time, each second vibration motor 613 needs to be activated to ensure the continuous movement of the plastic granules.
[0038] The air outlets of several suction hoods 614 fixed at the opening above the deceleration groove 612 are all connected to the dust removal system. After the dust removal system is started, the dust mixed in the plastic particles in the deceleration groove 612 will be sucked into the dust removal system through each suction hood 614, and then the impurities and dust will be separated.
[0039] Plastic particles leaving the lower end of the deceleration trough 612 fall to the edge near the top opening of the first guide hopper 622 and the top opening of the second guide hopper 623. Then, the distributing motor 626 in the distributing assembly 62 is started to rotate its rotating shaft, which in turn drives the distributing roller 624 to rotate towards the lower edge of the deceleration trough 612, thereby moving the plastic particles towards the lower edge of the deceleration trough 612. Plastic particles with a particle size within the normal range will rotate through the gap between the lower edge of the deceleration trough 612 and the distributing roller 624 to the top of the second guide hopper 623, and then fall into the second guide hopper 623. They then gather in the receiving hopper 63 and are discharged outward through the second discharge hopper 64. Large particles of impurities mixed in with the plastic particles and unable to pass through the gap will slowly fall into the first guide hopper 622 and be discharged outward through the first discharge hopper 628. This completes the impurity separation process of the plastic particles.
[0040] This invention enables continuous separation of different impurities within the same equipment, eliminating the need for plastic particles to be transferred between equipment multiple times. This avoids multiple feeding and discharging operations, simplifying the operation process and accelerating the processing speed to achieve time and labor savings. Furthermore, it saves money on equipment purchases, reducing processing costs, and also saves space occupied by the equipment, thus improving space utilization.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
