Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic masterbatch production technology, and in particular to a plastic masterbatch screening device. Background Technology
[0002] Screening of plastic masterbatch is a crucial step in the manufacturing process of plastic products. Its purpose is to separate particles of different sizes within the plastic masterbatch to obtain masterbatch particles that meet production requirements. Screening separates larger or smaller particles from the plastic masterbatch, ensuring the desired particle size. This prevents problems such as particle clogging, incomplete mixing, deformation, or damage during subsequent production processes. Plastic masterbatch may contain impurities or foreign objects, such as metals, sand, and fibers, which can affect subsequent production processes and product quality. Screening effectively removes these impurities and foreign objects, improving the purity of the masterbatch. Proper screening can control the particle size of the masterbatch within a small range, thereby shortening processing time and improving processing efficiency. The size and uniformity of the masterbatch particles directly affect the quality and performance of the final product. Correct screening ensures the quality and uniformity of the masterbatch, thus improving product quality. Therefore, screening of plastic masterbatch is a vital step in manufacturing high-quality plastic products and plays a significant role.
[0003] However, the production process of plastic masterbatch produces masterbatch of both large and small sizes. To obtain the final suitable masterbatch, multiple screenings are required. This results in a large number of screening devices, a large floor space required, and consequently, increased production costs.

A second motor 5 is provided at the other end of the rotating shaft 52.
[0025] Specifically, a pair of jackets 11 are symmetrically arranged on the side of the first separating tank 1. A first telescopic rod 12 is provided at the other end of the jacket 11. A telescopic seat 13 is coaxially provided at the other end of the first telescopic rod 12. A first motor 2 is provided at the other end of the telescopic seat 13. Plastic masterbatch is added into the first separating tank 1. The first separating tank 1 is clamped and fixed by the jackets 11. The two first motors 2 drive the first telescopic rod 12 to extend and retract in the same direction inside the telescopic seat 13, causing the jackets 11 to vibrate, thereby causing the first separating tank 1 to vibrate. A second separating tank 4 is coaxially arranged on the bottom surface of the first separating tank 1. A fixing hole 46 is provided at the center of the bottom surface of the second separating tank 4. A rotating shaft 52 is provided inside the fixing hole 46. A second motor 5 is provided at the other end of the rotating shaft 52. The rotating shaft 52 is fixed through the fixing hole 46, and the top surface of the rotating shaft 52 is flush with the top of the inner bottom surface of the second separating tank 4, sealing the bottom surface of the second separating tank 4. The second motor 5 drives the upgraded motor 51 to rotate, causing the second separating tank 4 to rotate.
[0026] Multiple first support rods 21 are evenly arranged on the bottom surface of the first motor 2. A first support plate 3 is arranged on the bottom surface of the first support rods 21. A second support plate 6 is arranged on the bottom surface of the second motor 5. The second support plate 6 is parallel to the first support plate 3. Support frames 61 are arranged on both sides of the top surface of the second support plate 6. The top of the support frame 61 is connected to the bottom surface of the first support plate 3.
[0027] Specifically, the first motor 2 is fixed by the first support plate 3, and the second support plate 6 and the first support plate 3 are connected and fixed by the support frame 61.
[0028] The first support plate 3 is provided with a through hole 31. The size of the through hole 31 is larger than the size of the first separation tank 1, and the center of the through hole 31 coincides with the center of the first separation tank 1.
[0029] Specifically, the bottom surface of the first separation tank 1 is inside the through hole 31 when it vibrates.
[0030] The bottom of the first separation tank 1 is provided with a screening plate 14, and a plurality of first screening holes 15 are evenly provided on the screening plate 14; the bottom of the screening plate 14 is provided with a guide tube 16, which is located inside the through hole 31, and the bottom surface of the guide tube 16 is flush with the bottom surface of the first support plate 3.
[0031] Specifically, through the vibration of the first separation tank 1, the masterbatch with a top size larger than the first screening hole 15 is isolated on the screening plate 14. The other masterbatch, under the vibration of the first separation tank 1, passes through the first screening hole 15 and enters the guide tube 16, and is then passed into the interior of the screening tank 42 through the guide tube 16.
[0032] The second separation tank 4 has a screening tank 42 coaxially arranged inside. The size of the screening tank 42 is larger than that of the first separation tank 1. Multiple second screening holes 43 are evenly arranged on the side of the screening tank 42. Multiple second screening holes 43 are also evenly arranged on the bottom surface of the second separation tank 4 on the outside of the screening tank 42. The size of the second screening holes 43 is smaller than that of the first screening holes 15.
[0033] Specifically, the rotation of the second separation tank 4 causes the masterbatch inside the screening tank 42 to rotate as well, throwing out the smaller masterbatch from the second screening hole 43 on the screening tank 42 and discharging it from the second screening hole 43 on the bottom surface of the second separation tank 4, leaving the masterbatch of the correct size inside the screening tank 42.
[0034] The second separating tank 4 has a pair of discharge holes 44 on the inner bottom surface of the screening tank 42. The discharge holes 44 are equipped with a sealing plate 45 inside.

The other end of the second telescopic rod 53 is equipped with an upgrade motor 51. The side of the upgrade motor 51 fits the side of the second motor 5. The top surface of the upgrade motor 51 is connected to the top surface of the second support plate 6.
[0035] Specifically, by upgrading the motor 51 to drive the sealing plate 45 to rise and fall, the qualified masterbatch inside the screening tank 42 is discharged, and the second support plate 6 provides support for the upgraded motor 51.
[0036] The bottom surface of the second separation tank 4 is provided with a discharge pipe 41 on the outside of the screening tank 42.
[0037] Specifically, the masterbatch inside the screening tank 42 is separated from the masterbatch discharged from the second screening hole 43 by the discharge pipe 41. The side of the discharge pipe 41 is frustum-shaped. The masterbatch discharged from the second screening hole 43 is dispersed outward through the side of the discharge pipe 41, thus separating the two types of masterbatch.
[0038] During use, the masterbatch is added into the first separating tank 1, and the first motor 2 is started to drive the first separating tank 1 to vibrate, isolating the larger masterbatch inside the first separating tank 1 inside the jacket 11, and extracting the masterbatch remaining inside the first separating tank 1; the smaller masterbatch enters the screening tank 42, and the second motor 5 is started to drive the second separating tank 4 to rotate, discharging the smaller masterbatch inside the screening tank 42 from the second screening hole 43. Then the upgrade motor 51 is started to open the bottom of the screening tank 42, and the suitable masterbatch inside the screening tank 42 is taken out from the discharge pipe 41. After two screenings, the masterbatch of the appropriate size is finally obtained.
