[0002] Plastic particles have a wide range of applications. In daily life, recycled particles can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and various plastic products. In the clothing industry, they can be used to make clothing, ties, buttons, and zippers. In terms of building materials, unqualified plastic particles need to be screened out during processing to facilitate subsequent manufacturing.

[0003] Patent No. CN218196273U discloses a screening mechanism for a plastic particle screening device, including a screening box, the inner wall of the screening box is slidably connected to a No. 1 screening plate and a No. 2 screening plate, the inner wall of the screening box is fixedly connected to an inclined side plate, the bottom of both sides of the inner wall of the screening box is provided with a reset assembly, and the bottom of the inclined side plate is fixedly connected to a No. 1 bump, a No. 2 bump and a telescopic rod. Through the coordinated use of a connecting assembly, a mounting screw hole, a connecting screw, a No. 1 screening plate, a No. 2 screening plate, a cam, a dual-axis motor, a No. 1 bump, a No. 2 bump, a cam, a rotating shaft and a reset assembly, the particle size within the three ranges can be screened respectively, the plastic particles remaining on the surface of the No. 1 screening plate are larger, the plastic particles remaining on the surface of the No. 2 screening plate are medium in size, and the smaller plastic particles will be screened to the surface of the inclined side plate, so as to realize the screening of plastic particles of different sizes.

[0004] In the prior art, during screening, plastic particles roll down onto the No. 1 sieve plate and the No. 2 sieve plate in turn, and are screened into plastic particles of different sizes by the sieve plates with different mesh sizes, and then separated and collected. However, in actual use, the sieve holes of the sieve plate may become clogged after working for a long time. In the event of blockage, the plastic particles cannot be effectively screened when they fall on the sieve plate, and are thus directly collected. This results in the collected plastic particles being of non-uniform size, and the plastic particles need to be screened again, or used directly, which results in a decrease in the quality of the finished product, thereby affecting the progress of the work.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0031] During operation, in the prior art, during screening, the plastic particles roll down to the No. 1 screening plate and the No. 2 screening plate in turn, and are screened into plastic particles of different sizes by the screening plates with different mesh sizes, and then are separated and collected. However, in actual use, the screening holes of the screening plates may be blocked after working for a long time. In the case of blockage, the plastic particles cannot be effectively screened when they fall on the screening plates, and are directly collected, which results in the non-uniform size of the collected plastic particles, so that the plastic particles need to be screened again, or directly used, resulting in a decrease in the quality of the finished product, which in turn affects the progress of the work. In order to prevent such incidents from occurring, first, the plastic particles enter the machine body 1 through the feed bin 21 in the feed assembly 2 for screening. During screening, the plastic particles are first screened by the first filter plate 6, which is set as an inclined surface. During the screening process, the plastic particles continue to slide down and are screened during the sliding process. After the screening is completed by the first filter plate 6, The plastic particles slide onto the second filter plate 7. The aperture of the second filter plate 7 is smaller than that of the first filter plate 6, and the plastic particles can be subdivided. When the plastic particles are screened by the second filter plate 7, the screened plastic particles will fall on the discharge conveyor belt 8 just below the second filter plate 7, and the unscreened plastic particles will continue to slide until they fall on the re-feeding conveyor belt 9 at the tail end of the second filter plate 7. At this time, the re-feeding conveyor belt 9 works to convey the plastic particles to the feed bridge 5 on the side wall of the feeding cylinder 5. 6, and then slide from the feed bridge 56 into the feed barrel 5. After the plastic particles enter the feed barrel 5, the feed shaft 57 rotates to drive the feed blades 53 to bring the plastic particles to the top of the feed barrel 5. After reaching the top, the plastic particles are discharged from the discharge bridge 52 at the discharge port 55, and then slide from the discharge bridge 52 to the feed bin 21, and then enter the body 1 through the feed bin 21 for repeated screening, until all the plastic particles to be classified are screened, and the unqualified plastic particles are screened out for processing.

[0033] During operation, first, the plastic particles are put into the feed bin 21 from the feeding port 22, and then guided by the feeding blades 24 in the feed bin 21 to avoid the plastic particles being poured in at one time, which reduces the screening effect. The plastic particles conveyed by the feeding cylinder 5 can enter the feed bin 21 from the feeding port 11 again to achieve repeated screening.

[0034] like Figure 3As shown, the first filter plate 6 and the second filter plate 7 are rotatably connected to the side wall of the body 1; a vibration unit is provided at one end of the first filter plate 6 and the second filter plate 7 away from the side wall of the body 1; the vibration unit includes a vibration box 10; a vibration groove 101 is provided in the vibration box 10; a vibration column 102 is fixedly connected in the vibration groove 101; the vibration column 102 is driven to vibrate by a driving force; a vibration block 103 is fixedly connected at one end of the vibration column 102 away from the vibration groove 101; the end of the vibration block 103 away from the vibration column 102 abuts against the bottom of the first filter plate 6 and the second filter plate 7;

[0035] During operation, when filtering, in order to prevent plastic particles from clogging the first filter plate 6 and the second filter plate 7, a vibration unit is arranged underneath them, which includes a vibration box 10. When screening, the vibration column 102 in the vibration box 10 is driven to vibrate. During vibration, the vibration block 103 is used to drive the first filter plate 6 and the second filter plate 7 to vibrate continuously, so that the plastic particles stuck in the holes can be vibrated down to avoid clogging.

[0036] like Figure 2 and Figure 3 As shown, the side wall of the machine body 1 is fixedly connected with a guide plate 71; the guide plates 71 are provided in two groups; a feed plate 72 is fixedly connected to the side wall of the machine body 1 below the guide plates 71; a feed opening 73 is provided in the middle of the feed plate 72; the feed plate 72 is provided above the re-feeding conveyor belt 9;

[0037] During operation, the plastic particles that are not filtered by the second filter plate 7 will slide onto the guide plate 71. There are two groups of guide plates 71. After being guided by the two groups of guide plates 71, the plastic particles can slide to the discharge port 73 opened on the lower discharge plate 72, pass through the discharge port 73 to reach the re-feeding conveyor belt 9, and then be transported to the feed cylinder 5 through the re-feeding conveyor belt 9 for repeated screening.

[0038] like Figure 1 As shown, the top of the feeding cylinder 5 is fixedly connected to a feeding motor 51; the feeding shaft 57 is driven to rotate by the feeding motor 51; the side wall of the feeding bin 21 is fixedly connected to a feeding motor 25; the feeding shaft 23 is driven to rotate by the feeding motor 25;

[0040] like Figure 1 and Figure 2 As shown, the side walls of the first filter plate 6 and the second filter plate 7 are fixedly connected with a side plate 61; the side wall of the body 1 is hinged with a protective door 4;

[0041] During operation, when plastic particles are filtered, the side plates 61 can prevent the plastic particles from sliding off the two sides of the first filter plate 6 and the second filter plate 7. When the screening is finished, the protective door 4 can be opened to clean the first filter plate 6 and the second filter plate 7.

[0042] like Figure 1 and Figure 2 As shown, the body 1 is fixedly connected to the bottom of the feeding cylinder 5 with a support leg 3; the bottom of the support leg 3 is fixedly connected to a rubber pad 31;

[0043] During operation, the support legs 3 can support the machine body 1 and the feed tube 5 , and the rubber pads 31 can prevent the support legs 3 from slipping.

[0044] Working principle of the utility model: In the prior art, during screening, plastic particles roll down to the No. 1 screening plate and the No. 2 screening plate in turn, and are screened into plastic particles of different sizes by the screening plates with different mesh sizes, and then are separated and collected. However, in actual use, the screening holes of the screening plates may be blocked after working for a long time. In the case of blockage, the plastic particles cannot be effectively screened when they fall on the screening plates, and are directly collected, which results in the collected plastic particles being of non-uniform size, so that the plastic particles need to be screened again, or directly used, resulting in a decrease in the quality of the finished product, which in turn affects the progress of the work. In order to prevent such incidents from occurring, first, the plastic particles enter the machine body 1 through the feed bin 21 in the feed assembly 2 for screening. During screening, the plastic particles are first screened by the first filter plate 6, which is set as an inclined surface. During the screening process, the plastic particles continue to slide down and are screened during the sliding process. The plastic particles are screened by the first filter plate 6. After completion, the plastic particles slide onto the second filter plate 7. The aperture of the second filter plate 7 is smaller than that of the first filter plate 6, and the plastic particles can be subdivided. When the plastic particles are screened by the second filter plate 7, the screened plastic particles will fall on the discharge conveyor belt 8 just below the second filter plate 7, and the unscreened plastic particles will continue to slide until they fall on the re-feeding conveyor belt 9 at the tail end of the second filter plate 7. At this time, the re-feeding conveyor belt 9 works to convey the plastic particles to the feed conveyor belt on the side wall of the feeding cylinder 5. The plastic particles are placed on the feed bridge 56 and then slide from the feed bridge 56 into the feed barrel 5. After the plastic particles enter the feed barrel 5, the feed shaft 57 rotates to drive the plastic particles on the feed blades 53 to the top of the feed barrel 5. After reaching the top, the plastic particles are discharged from the discharge bridge 52 at the discharge port 55, and then slide from the discharge bridge 52 to the feed bin 21, and then enter the machine body 1 through the feed bin 21 for repeated screening, until all the plastic particles to be classified are screened, and the unqualified plastic particles are screened out for processing.

[0045] Among them, the plastic particles can be guided by the feeding component 2 to avoid blockage caused by excessive entry of plastic particles. First, the plastic particles are put into the feed bin 21 from the feeding port 22, and then guided by the feeding blades 24 in the feed bin 21 to avoid the plastic particles being poured in all at once, which reduces the screening effect. The plastic particles conveyed by the feeding barrel 5 can enter the feed bin 21 from the feeding port 11 to achieve repeated screening.

[0046] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
