Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to a cooling device for a plastic production line. Background Art

[0002] In the production process of the plastic extruder, the plastic particles are first heated to make them present a viscous flow state, and then, under pressure, they are made to pass through a discharge die with a certain shape to become a plastic product with a cross-section similar to the discharge die shape. Since the plastic product is still in the plastic stage just after being extruded from the plastic extruder, it is necessary to cool it so that the plastic product is cooled and shaped to obtain the desired plastic finished product. In the prior art, since water has a large specific heat capacity and is easy to exchange heat with hot plastic products, and the chemical properties of water are stable, water cooling is mostly used for cooling plastic particles. However, after the plastic product passes through the plastic extruder, it is directly cooled by flushing with water, which causes the flowing water to easily flush the plastic product that has not been fully shaped and deform it, causing damage to the plastic product. Therefore, we propose a cooling device for a plastic production line to solve the above problem. Utility Model Content
