Description

Technical Field

[0002] Masterbatch, also known as color seed, is a new type of colorant specially used for polymer materials, also known as pigment preparation. Masterbatch is mainly used in plastics. It is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment into the resin. It can be called pigment concentrate, so its tinting power is higher than the pigment itself.

[0003] The existing masterbatch slitting mechanism, for example, a new masterbatch cutting device disclosed in the utility model patent with application number 202022480954.0, has a main structure including an upper plate, the right side of the upper plate is connected to the left side of the box body, an electric push rod 1 is provided inside the box body, and a mounting plate is fixedly provided at the bottom end of the electric push rod 1, and three groups of cutters are fixedly provided at the bottom end of the mounting plate; when in use, as soon as the conveyor starts working, the plastic strips produced by the die head of the previous process extruder fall on the conveyor 1 and are transported to the right side. Since the number of plastic strips passing through the baffle pair is limited, only one plastic strip is allowed to pass through the opposite side of the two baffles 1 at a time. The conveyor 1 allows the plastic strip to enter the inner side of the baffle 1, and then move to the bottom inner wall of the box body. The left end of the baffle 2 touches the right side of the plastic strip to locate the position of the plastic strip. At this time, the electric push rod 1 is started, and the cutter on the electric push rod 1 moves downward to cut the plastic strip.
