Description

Technical Field

[0001] This utility model relates to the field of engineering plastics preparation technology, and in particular to a screening device for engineering plastics preparation. Background Technology

[0002] Engineering plastics are plastics used as engineering materials and to replace metals in the manufacture of machine parts. They possess excellent comprehensive properties, including high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation, allowing for long-term use in harsh chemical and physical environments. During the preparation process, materials of different sizes need to be sieved as needed for subsequent processing.

[0003] As shown in application number CN202320673945.4, an engineering plastic preparation screening device includes: a base plate, a waste bin, four columns, and two support plates mounted on the upper surface of the base plate; a screening cylinder supported on the top of the four columns; and a rotating rod rotatably mounted between the two support plates. This utility model's engineering plastic preparation screening device uses a rotary motor to drive the rotating rod to rotate counterclockwise, which, in conjunction with spiral blades, propels the engineering plastic within the screening cylinder cavity, completing the screening of engineering plastics of different sizes and specifications.

[0004] In the above-mentioned screening process, a large amount of material is screened through the screening holes at the bottom of the screening cylinder, which may cause the screening holes to become clogged, affecting work efficiency and results. Utility Model Content

[0005] To address the problem that screening mesh may become clogged by materials, this invention provides a screening device for the preparation of engineering plastics.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] Example 1, combined with Figure 1 Explanation:

[0025] A screening device for preparing engineering plastics includes: a vibrating base 1, a screening seat 2, a drive shaft 3, a screening box 4, a screening screen cover 5, and a drive motor 6. The screening seat 2 is rotatably mounted on the vibrating base 1, the drive shaft 3 is rotatably mounted on the screening seat 2, multiple screening boxes 4 are provided, and multiple screening boxes 4 are fixedly mounted on the drive shaft 3. The screening screen cover 5 is fixedly mounted on the screening box 4, and the drive motor 6 is fixedly mounted on the screening seat 2. The output end of the drive motor 6 is fixedly mounted on the drive shaft 3.

[0026] With this configuration, the drive motor 6 drives the drive shaft 3 to rotate, causing the material inside the screening box 4 on the drive shaft 3 to move. The screening screen 5 screens the material, and the screening seat 2 collects the screened material. Rotating the screening box 4 causes the screening screen 5 to rotate, separating the screening screen 5 from the material and reducing the possibility of clogging the screening holes. The screening seat 2 is mounted on the vibrating base 1, and the vibrating base 1 vibrates the screening seat 2, improving screening efficiency and reducing the possibility of clogging the screening screen 5.

[0027] Example 2, based on Example 1, combined with... Figure 2 Explanation:

[0028] The drive shaft 3 includes a shaft body 7, a sealing plate 8, and a support ring 9. The shaft body 7 is rotatably mounted on the screening seat 2 and is fixedly connected to the output end of the drive motor 6. Two sets of sealing plates 8 are provided and fixedly mounted on the shaft body 7. Multiple sets of support rings 9 are provided and fixedly mounted on the shaft 7. The support rings 9 are fixedly mounted between two sets of sealing plates 8 and have through holes. The screening box 4 is fitted onto the sealing plates 8 and the support rings 9. A feed inlet 11 is provided on the end face of the shaft body 7. A through groove 10 is provided on the shaft body 7 between the sealing plate 8 and the support ring on one side of the feed inlet 11. The shaft 7 is inclined, and the feed inlet 11 is inclined upward.

[0029] In this configuration, the shaft 7 is rotatably mounted on the screening seat 2, and the screening box 4 is fixed in place by the cooperation of the sealing plate 8 and the support ring 9. The sealing plate 8 is installed at both ends of multiple screening boxes 4 to seal and prevent material leakage. Adjacent screening boxes 4 are connected by the support ring 9 to facilitate material transfer. The through hole on the support ring 9 is much larger than the material volume, allowing the material to pass through smoothly. The material is loaded through the feed port 11 on the shaft 7 and enters the screening box 4 through the through groove 10. The rotating drive shaft 3 drives the screening screen 5 to rotate. The inverted screening screen 5 prevents the screening holes from clogging and improves working efficiency.

[0030] Example 3, based on Example 2, combined with Figure 3 Explanation:

[0031] The screening box 4 has an eccentric shaft hole 12, which is tangent to the inner wall of the screening box 4. The sealing plate 8 or support ring 9 is fixedly installed in the eccentric shaft hole 12. The screening box 4 has a screening groove 13, and the screening screen cover 5 is fitted onto the screening groove 13. Multiple sets of screening boxes 4 are provided, and when multiple sets of screening boxes 4 are fixedly installed on the drive shaft 3, the multiple sets of screening boxes 4 are staggered. The multiple sets of screening boxes 4 are provided with screening screen covers 5 of different screen hole sizes. The screening screen cover 5 with the smallest screen hole is fixedly installed on the screening box 4 on the side of the feed inlet 11, and the multiple sets of screening screen covers 5 are arranged from small to large.

[0032] With this configuration, the material is fixed to the support ring 9 through the eccentric shaft hole 12 on the screening box 4. The eccentric shaft hole 12 is tangent to the inner wall of the screening box 4, ensuring that the material enters the adjacent screening box 4 as much as possible through the support ring 9. The staggered arrangement of multiple screening boxes 4 can improve the balance and working efficiency of the device. The material is screened by multiple screening screens 5 arranged from small to large.

[0033] Example 4, based on Example 3, combined with Figure 4 Explanation:

[0034] The screening seat 2 includes: a seat body 14, an inclined baffle 15, and a support plate 16. The inclined baffle 15 and the support plate 16 are provided with drive shaft holes 18. The drive shaft 3 is rotatably disposed in the drive shaft hole 18. The axis of the drive shaft hole 18 is perpendicular to the inclined surface of the inclined baffle 15. The seat body 14 is provided with a rotating shaft hole 17 and a material box 19. The material box 19 is configured to cooperate with the screening box 4. The vibrating base 1 includes: a support base 20, a limiting plate 25, a vibrating motor 24, a vibrating shaft 22, and an eccentric wheel 23. The limiting plate 25 is fixedly disposed on both sides of the support base 20, and a rotating hole 26 is provided on the limiting plate 25. The rotating shaft hole 17 and the rotating hole 26 are configured to cooperate. An eccentric wheel groove 21 is provided on the support base 20, and the vibrating shaft 22 is rotatably disposed in the eccentric wheel groove 21. The vibrating motor 24 is fixedly disposed on the support base 20, and the output end of the vibrating motor 24 is fixedly disposed on the vibrating shaft 22. An eccentric wheel 23 is fixedly disposed on the vibrating shaft 22, and the eccentric wheel 23 abuts against the bottom surface of the screening seat 2.

[0035] With this configuration, the drive shaft 3 is supported by the drive shaft hole 18 on the inclined baffle 15 and the support plate 16. The inclined surface of the inclined baffle 15 abuts against the side of the screening box 4, providing support for the screening box 4. The material box 19 on the seat 14 collects the screened material. The width of the material box 19 is greater than the width of the screening screen 5, ensuring that the material does not splash into other material boxes 19 when it comes out of the screening screen 5. The seat 14 is rotatably mounted on the limiting plate 25 through the rotating shaft hole 17. The bottom surface of the seat 14 abuts against the eccentric wheel 23. The oscillating motor 24 drives the eccentric wheel 23 to rotate. The eccentric wheel 23 pushes the seat 14 to oscillate, improving the screening efficiency of the screening box 4 and reducing the possibility of clogging of the screening screen 5.

[0036] The working principle of this utility model is as follows: The drive motor 6 drives the drive shaft 3 to rotate, causing the material inside the screening box 4 on the drive shaft 3 to move. The screening screen 5 screens the material inside. The rotating drive shaft 3 drives the screening screen 5 to rotate. The inverted screening screen 5 prevents the screening holes from clogging and improves working efficiency. The support ring 9 connects the adjacent screening boxes 4. The inclined drive shaft 3 allows the material to pass through the support ring 9 into the adjacent screening box 4 for further screening. The oscillating motor 24 drives the eccentric wheel 23 to rotate, causing the eccentric wheel 23 to drive the base 14 to oscillate, improving the working efficiency of screening and reducing the possibility of screening hole clogging. This utility model has a simple structure and significant effect. It screens the material through multiple sets of screening screens 5, prevents the material from clogging the holes of the screening screens 5 through multiple sets of rotating screening boxes 4, and improves the prevention effect and screening efficiency through the oscillating base 1.
