Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a masterbatch screening device for PE foaming plates. Background Art

[0002] PE foam board, also known as polyethylene foam board, is made of polyethylene as raw material and is foamed with carbon dioxide gas. It has a thickness of 1 mm to 20 mm, has excellent thermal stability and dimensional stability of products at high temperatures, has a suitable and soft surface, excellent microwave adaptability and degradability, excellent processability, and related properties can be adjusted according to product performance and use.

[0003] Masterbatch, also called color seed, is a new type of colorant for polymer materials. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive, so its tinting power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored PE foam sheet to achieve the coloring resin or product with the designed pigment concentration. Before processing, the masterbatch particle size varies greatly, which is easy to cause inaccurate measurement during use and needs to be screened.

[0004] The current masterbatch screening device, due to the uneven size of the masterbatch, is easy to agglomerate at high temperature, and most of them are only screened by sieves, which is not accurate and the efficiency is too low. The masterbatch with larger particles is not conducive to its full stirring during coloring, affecting the efficiency. Therefore, we propose a masterbatch screening device for PE foam board.

A driving motor 15 is bolted to one side of the stirring box 14. The output end of the driving motor 15 passes through the stirring box 14 and is connected to a stirring rod 16 for transmission. A stirring blade 17 is fixedly welded on the outer side of the stirring rod 16. By setting the stirring rod 16, the masterbatch particles in the stirring box 14 can be stirred and dispersed.

[0028] Among them, a feed port 18 is fixedly connected to one side of the mixing box 14, a discharge port 19 is fixedly connected to one side of the mixing box 14, and a discharge bin door 20 is arranged on the upper part of the discharge port 19. By setting the discharge bin door 20, mixing and discharging are convenient.

[0029] Among them, a hook 21 is provided on the outside of the mixing box 14, and a U-shaped column is fixedly connected to the top of the discharge bin door 20. By setting the hook 21, the hook 21 can be used to limit the U-shaped column on the top of the discharge bin door 20 when the masterbatch particles are discharged, so as to facilitate the discharge.

[0030] Among them, the lower end of the mixing box 14 is fixedly connected to the dust removal box 22, and a dust outlet 23 is opened at the lower end of the mixing box 14. The interior of the dust removal box 22 is slidably connected to a dust drawer 24. The interior of the dust removal box 22 is fixedly installed with a dust removal fan 25.

At the same time, the masterbatch particles in the stirring box 14 are heat-absorbed and cooled. After stirring, open the discharge bin door 20, and the discharge bin door 20 is opened through the hook 21. The silo door 20 is limited and fixed, and the vibration motor 11 is started. The mixed masterbatch particles fall onto the screen 9 through the receiving plate 10 for screening, and fall into the unloading plate 2 through the screen 9 for discharge. The masterbatch particles that do not pass through the screen 9 are discharged through the baffle 26 or returned to the mixing box 14 for secondary screening. When different specifications and sizes are required, the screen 9 can be disassembled and replaced, and the rotation angle of the screen box frame 8 can be adjusted by adjusting the angle of the rotating frame 4 through the adjusting plate 5, which is convenient for the screening work of the staff.
