Detailed Implementation

[0028] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0029] like Figures 1 to 4 As shown, this embodiment proposes a masterbatch screening device, including a first screening module 11, a second screening module 12 and a support frame 13. The support frame 13 is used to install the first screening module 11 and the second screening module 12, with the first screening module 11 located above the second screening module 12.

[0030] The first screening module 11 is provided with a first screen 14, a first masterbatch flow channel 15 is formed above the first screen 14, and a second masterbatch flow channel 16 is formed below the first screen 14.

[0031] The second screening module 12 is provided with a second screen 17, a third masterbatch flow channel 18 is formed above the second screen 17, and a fourth masterbatch flow channel 19 is formed below the second screen 17.

[0032] The outlet of the first masterbatch flow channel 15 is connected to the fourth masterbatch flow channel 19 through a material guide channel, and the outlet of the fourth masterbatch flow channel 19 is used to discharge waste material.

[0033] The outlet end of the second masterbatch flow channel 16 is used to transport the masterbatch to the third masterbatch flow channel 18, and the outlet of the third masterbatch flow channel 18 is used to discharge qualified masterbatch.

[0034] In this scheme, the processed masterbatch is transported to the first screen 14 through a pipeline. The aperture of the first screen 14 is larger than that of the second screen 17. Unqualified large-particle masterbatch flows into the fourth masterbatch flow channel 19 through the first masterbatch flow channel 15 and the guide channel.

[0035] The masterbatch below the first screen 14 flows into the third masterbatch flow channel 18 through the second masterbatch flow channel 16. The powder or unqualified fine particles of masterbatch in the third masterbatch flow channel 18 fall into the fourth masterbatch flow channel 19 through the second screen 17. A hopper can be set at the output of the third masterbatch flow channel 18 to store qualified masterbatch.

[0036] The bottom of the fourth masterbatch flow channel 19 is provided with an outlet for discharging unqualified waste. It can be stored in a separate waste bin or directly transported to the furnace for secondary processing through a pipeline.

[0037] The apertures of the first screen 14 and the second screen 17 in this scheme can be adjusted according to processing needs. The particle size of the qualified masterbatch is larger than the mesh size of the second screen 17 and smaller than the mesh size of the first screen 14.

[0038] This solution can remove both large and small particle sizes of masterbatch, while also saving space in the equipment.

[0039] The preset particle size range for qualified masterbatch in this scheme can be set to 3 to 5 mm. Any particle size larger than this preset particle size range is considered a larger particle size, and any particle size smaller than this preset particle size range is considered a smaller particle size.

[0040] The masterbatch screening device in this solution can also be used to screen other masterbatches using the same principle. The applicable scenarios can be expanded by replacing the first screen 14 and the second screen 17.

[0041] In one embodiment of this invention, the first screening module 11 and the second screening module 12 are both vibrating screens. The vibrating screens can be equipment from the prior art.

[0042] Furthermore, the first screen 14 and the second screen 17 are respectively arranged at an angle.

[0043] As one embodiment of this invention, a material guiding component 20 is provided between the first screening module 11 and the second screening module 12, and the material guiding component 20 has the material guiding channel.

[0044] As one embodiment of this invention, the material guiding assembly 20 includes:

[0045] A first material guiding part 21 is fixed on a first screening module 11, and a first channel 22 is provided through the first material guiding part 21.

[0046] The second material guiding part 23 is fixed on the second screening module 12, and a second channel 24 is provided through the second material guiding part 23.

[0047] The first channel 22 and the second channel 24 are connected to form the material guiding channel.

[0048] Furthermore, the lower end of the first guide section 21 can be slidably inserted into the second channel 24 in the vertical direction.

[0049] The technical advantage of this solution is that, since both the first screening module 11 and the second screening module 12 require vibration, a split design is adopted, utilizing the sliding connection between the first guide part 21 and the second guide part 23 to fully ensure the operation of the first screening module 11 and the second screening module 12.

[0050] As one embodiment of this example, the vibrating screen itself includes a housing and an elastic support member 25. The housing is mounted on the support frame 13 through the elastic support member 25. The support frame 13 is fixed with a drive assembly 26, which is used to drive the vibrating screen to vibrate in the vertical direction.

[0051] In one embodiment of this invention, the drive assembly 26 includes a mounting base 27, a motor 28, and a cam 29. The motor 28 is mounted on the support frame 13 via the mounting base 27. The cam 29 is fixed on the output shaft of the motor 28 and is used to press the bottom surface of the vibrating screen.

[0052] When the motor 28 is working, the output shaft of the motor 28 rotates, which drives the cam 29 to rotate. The cam 29 intermittently presses the bottom surface of the vibrating screen shell. Under the action of the elastic support 25, the vibrating screen vibrates.

[0053] The shell of the vibrating screen and the internal screen plate are existing technologies.

[0054] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
