Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0021] Reference Figure 1-Figure 3 A polyphenylene sulfide modified masterbatch screening device comprises a box body 1 and a sealing plug 3. Two inclined screens 14 and an inclined plate 11 are fixedly installed in the box body 1. The two screens 14 are arranged in an eight-shaped shape. A feed hopper 6 is fixedly connected to the upper surface of the box body 1. A circular hole connected to the feed hopper 6 is opened on the box body 1. A servo motor is fixedly arranged on the lower inner wall of the box body 1. A rotating shaft 12 is fixedly connected to the driving end of the servo motor. Each screen 14 and the inclined plate 11 are rotatably connected to the rotating shaft 12. A moving component is arranged at the upper end of the rotating shaft 12. The moving component comprises a reciprocating screw rod 15 fixedly arranged at the upper end of the rotating shaft 12. A fixed sleeve 8 is threadedly connected to the reciprocating screw rod 15. A sealing cover plate 7 is connected to the fixed sleeve 8 through two support rods 16. A knocking component is arranged inside the box body 1.

[0022] The knocking assembly includes a plurality of knocking rods 9 arranged in an eight-shaped shape, each of which is connected to the inner wall of the box body 1 through a torsion spring 10, and a moving block 4 with a T-shaped cross section is slidably installed in the box body 1, and a first spring 5 is sleeved on the moving block 4, one end of the first spring 5 is fixedly connected to the moving block 4, and the other end of the first spring 5 is fixedly connected to the outer surface of the box body 1, each knocking rod 9 is in contact with the surface of the moving block 4, and an extrusion rod 13 is fixedly connected to the rotating shaft 12, and the cross section of the extrusion rod 13 is circular, and the cylindrical extrusion rod 13 can effectively prevent the accumulation of raw materials on the surface.

[0023] As the extrusion rod 13 rotates along with the rotating shaft 12, the moving block 4 is squeezed. As the moving block 4 and the box body 1 slide relative to each other, the first spring 5 is deformed, and the moving block 4 squeezes each knocking rod 9. The knocking rod 9 rotates relative to the box body 1 at the same time. Since one end of the torsion spring 10 is fixedly connected to the knocking rod 9 and the other end is fixedly connected to the inner wall of the box body 1, the torsion spring 10 is deformed at the same time. After each knocking rod 9 rotates, it will knock on the two screens 14 respectively. The screens 14 vibrate to facilitate the raw materials to pass through the screens 14 quickly, which is beneficial to improving the efficiency of raw material screening.

[0024] A slide groove is provided on the inner wall of one side of the box body 1, and a limit rod 17 is slidably arranged in the slide groove. The limit rod 17 is fixedly connected to the fixed sleeve 8, and the limit rod 17 can limit the moving trajectory of the fixed sleeve 8 to prevent the fixed sleeve 8 from swinging. The cross-sections of the fixed sleeve 8 and the sealing cover plate 7 are both isosceles trapezoidal, which can effectively prevent the accumulation of raw materials on their surfaces. The box body 1 is connected to the box door through multiple bolts, and a transparent observation window 2 is fixedly arranged on the box door. The screening of the raw materials can be intuitively seen through the transparent observation window 2 made of transparent glass. After taking out the sealing plug 3, the discharge port will be exposed to the outside, and the screened raw materials on the inclined plate 11 can be discharged through the discharge port.

[0025] In the utility model, when in use, a large amount of raw materials are put into the feed hopper 6, and the servo motor works at the same time, the servo motor drives the rotating shaft 12 to rotate, and then drives the reciprocating screw rod 15 to rotate together. In the initial state, the sealing cover plate 7 and the inner wall of the feed hopper 6 are in close contact (such as the attached Figure 2 As shown, during the rotation of the reciprocating screw 15, the fixed sleeve 8 will move up along the reciprocating screw 15. Since one end of each support rod 16 is fixedly connected to the fixed sleeve 8 and the other end is fixedly connected to the sealing cover plate 7, the sealing cover plate 7 will move up in the feed hopper 6, and the gap between the sealing cover plate 7 and the feed hopper 6 will gradually become larger, and the raw material will pass through the through hole from the gap and fall onto the screen 14 above. When the fixed sleeve 8 subsequently moves down to the initial position, the gap between the sealing cover plate 7 and the feed hopper 6 will gradually become smaller, avoiding too much raw material being put into the box body 1 per unit time, and effectively avoiding the phenomenon of accumulation and blockage during the feeding process. The raw materials are screened through the two screens 14 in turn, and the screening accuracy is high and the effect is good, which is beneficial to the screening of polyphenylene sulfide modified masterbatch.

[0026] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
