Description

Technical Field

[0001] The invention relates to the technical field of masterbatch processing, in particular to a raw material mixing device for masterbatch manufacturing. Background Art

[0002] Masterbatch, also known as color seed, is a new type of colorant for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. Masterbatch is composed of pigment or dye, carrier and additive as the basic elements. It is an aggregate made by uniformly attaching an extraordinary amount of pigment to the resin. Its coloring power is higher than the pigment itself. During processing, a small amount of masterbatch is mixed with uncolored resin to achieve the coloring resin or product with the designed pigment concentration.

[0003] The production and processing of masterbatches generally includes processes such as mixing, extrusion, and pelletizing. The existing masterbatch mixing processing is mostly carried out by mixing and stirring with stirring blades in a mixing barrel. However, since the stirring blades are mostly fixedly connected, some materials will adhere to the inner wall of the mixing barrel during the processing. If the materials adhered to the inner wall of the mixing barrel cannot be handled in time, the mixing ratio of the masterbatch raw materials will be inaccurate, affecting the quality of the masterbatch. Summary of the invention

[0004] The purpose of the present invention is to provide a raw material mixing device for masterbatch manufacturing, so as to solve the problem in the prior art that during the mixing process of the masterbatch raw materials, materials may adhere to the inner wall of the stirring device, resulting in inaccurate mixing ratio of the masterbatch raw materials and affecting the quality of the masterbatch.

[0006] The technical principle of this scheme is: the material is poured into the mixing barrel through the feeding port through the feeding mechanism on the equipment frame, and then the driving mechanism is used to control the baffle to block and close the feeding port. The stepper motor is started, and the stepper motor drives the square rod to rotate in the mixing barrel, and the square rod drives the square tube and the connecting rod to rotate. During the rotation process, the connecting rod is affected by the centrifugal force and slides out of the square tube, and the square tube and the connecting rod stir and mix the material in the mixing barrel.

[0007] During the material mixing process, by adjusting the rotation speed of the stepper motor and controlling the distance of the connecting rod extending out of the square tube, the scraper on the connecting rod can scrape and clean the inner wall of the mixing cylinder and the conical cylinder to prevent the material from adhering to the inner wall of the mixing cylinder and the conical cylinder.
