Description

Technical Field

[0001] The utility model belongs to the technical field of masterbatch production, and in particular relates to cooling equipment for antistatic masterbatch processing. 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 known as pigment preparation. 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 a colored resin or product with a designed pigment concentration. It is mainly used in plastics. In the production process of masterbatch, the stirred plastic melt needs to be put into an extruder to extrude into strips. After cooling, the plastic strips are cut into shape by a pelletizer.

The utility model is provided with a fan and a water tank, and the masterbatch is fully cooled by air cooling and water cooling technology. Water inlet pipes are arranged on both water tanks so that water can be recycled.

[0004] However, the above utility model still has some shortcomings:

[0005] During the use of the above-mentioned utility model, the masterbatch to be cooled after cutting is poured into the condenser from the feed port for cooling. The masterbatch with higher temperature is easy to collide with each other when entering the condenser, causing it to stick together and become difficult to separate after cooling. In addition, when passing through the condenser, some of the masterbatch blocks are easy to collide with each other, enter the area where the fan is located through the pipeline, and collide with the fan blades in the fan, causing damage to the fan.
