Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to cooling equipment for plastic particle processing. Background Art

[0002] Plastic granules refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics and special plastics.

[0003] Plastic raw materials need to go through a specific processing flow to be plasticized and drawn into continuous plastic wires. These plastic wires are long strips in shape, which provides a basis for subsequent cooling treatment. Water cooling of these newly made plastic wires is a key step to ensure the quality of plastic particles. Water cooling can not only effectively reduce the temperature of the plastic wires, but also promote crystallization inside the plastic, thereby improving its physical properties. However, different plastic raw materials have different water absorption due to differences in their chemical structure and intermolecular forces. During the water cooling process, the time the plastic wire stays in the water needs to be adjusted according to the characteristics of the raw materials.

[0004] The existing cooling equipment for plastic particle processing can adjust the time the plastic line stays in the water by adjusting the height of different numbers of rolling shafts. However, the traditional method of adjusting the height of the rolling shaft is relatively complicated and inconvenient. Therefore, a cooling equipment for plastic particle processing is proposed to solve the above problem. Utility Model Content
