Description

Technical Field

[0001] The present invention relates to an extrusion system, in particular to an extrusion system for finally extruding masterbatch particles in the process of producing masterbatch particles. Background Art

[0002] As we all know, the full name of masterbatch is masterbatch, also called color seed. It is a new type of colorant for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment to the resin. It can be called pigment concentrate, so its coloring power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration.

[0003] Masterbatch particles have many advantages. First, they make the pigment have better dispersibility in the product. During the masterbatch production process, the pigment must be refined to improve the dispersibility and coloring power of the pigment. The carrier of the special masterbatch is the same as the plastic type of the product, and has good matching. After heating and melting, the pigment particles can be well dispersed in the plastic of the product. Secondly, it is conducive to maintaining the chemical stability of the pigment. If the pigment is used directly, the pigment will absorb water and oxidize due to direct contact with the air during storage and use. After being made into a masterbatch, the resin carrier isolates the pigment from the air and moisture, so the quality of the pigment can be kept unchanged for a long time. Thirdly, it ensures the stability of the color of the product. The masterbatch particles are similar to the resin particles, which are more convenient and accurate in measurement. They will not adhere to the container during mixing, and the mixing with the resin is also more uniform, so the addition amount can be guaranteed to be stable, thereby ensuring the stability of the color of the product. Finally, it can protect the health of the operator. The pigment is generally powdery, which is easy to fly when added and mixed, and will affect the health of the operator after being inhaled by the human body. It can keep the environment clean and easy to use.

[0004] like Figure 1 As shown, the process of producing masterbatch particles in the prior art is to put the mixed material into the extrusion equipment along the feed hopper, start the motor, drive the power shaft 1 to rotate in the extrusion barrel 2, and use the spiral convex strips 3 to extrude the material, so that the material is finally extruded along the sieve holes on the sieve plate 4 to obtain the finished masterbatch particles.

[0005] To summarize the above production methods, the prior art produces masterbatch particles by simple screw extrusion, and the masterbatch particles produced generally have many disadvantages such as uneven particle density, loose internal structure of particles, and poor particle quality. Summary of the invention

[0006] The technical solution adopted by the present invention is: a masterbatch particle extrusion system, which includes a basic extrusion part, a material narrowing extrusion part, a longitudinal material extrusion part and a transverse extrusion part, the material narrowing extrusion part is connected to the basic extrusion part, the longitudinal material extrusion part is connected between the material narrowing extrusion part and the transverse extrusion part, the basic extrusion part includes an extrusion cylinder and an extrusion rod, the extrusion rod is arranged in the extrusion cylinder, a spiral extrusion sheet is arranged on the extrusion rod, the extrusion cylinder has an extrusion cylinder discharge port, the masterbatch material is placed in the basic extrusion part, the masterbatch material in the extrusion cylinder is gradually extruded from back to front through the extrusion cylinder discharge port into the material narrowing extrusion part by rotating the extrusion rod and with the help of the spiral extrusion sheet, the masterbatch material in the material narrowing extrusion part is gradually extruded into the longitudinal material extrusion part, the masterbatch material in the longitudinal material extrusion part moves downward and is extruded into the transverse extrusion part in batches, and the masterbatch material in the transverse extrusion part is extruded from the transverse extrusion part in batches to obtain masterbatch.

[0007] The beneficial effects of the present invention are as follows: first, in the present invention, the masterbatch material can be compacted and tamped for the first time through the narrowing extrusion part of the material, and then, the masterbatch material can be compacted and tamped for the second time through the longitudinal material extrusion part, and finally, the masterbatch material can be compacted and tamped for the third time through the transverse extrusion part, and finally masterbatch particles are obtained. The masterbatch material is compacted and tamped for many times during the overall production process, which can improve the material density of the finished masterbatch particles, improve the compactness of the internal structure of the finished masterbatch particles, and significantly improve the quality of the finished masterbatch particles.
