Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch material strip shaping, in particular to a masterbatch material strip shaping mechanism after extrusion. Background Art

[0002] 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 tinting power is higher than the pigment itself.

[0003] When processing masterbatch, the masterbatch strips are first extruded through an extruder, followed by water cooling, drying, and finally pelletizing to obtain the masterbatch. During extrusion cooling, if no shaping treatment is performed, the edge of the masterbatch is easily flattened, resulting in a non-cylindrical structure of the masterbatch, which affects the shape of the masterbatch. At present, shaping is generally performed through two rollers with semicircular grooves, one of which is a fixed roller and the other can be raised and lowered. However, if two masterbatch strips of different specifications are extruded at the same time, only two separate shaping mechanisms can be installed, and the operation must be performed twice, which is inconvenient. At the same time, the shaping mechanism is generally installed above the cooling pool through a mounting frame, and the heights of the two shaping mechanisms cannot be the same, which also occupies additional space and greatly increases the installation requirements. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
