Description

Technical Field

[0001] The present invention relates to the field of plastic products, and in particular to a device and a method for producing plastic particles for plastic recycling. Background Art

[0002] With the widespread use of plastic products, the amount of plastic waste has increased dramatically, posing a serious threat to the environment. Plastic recycling has become one of the key ways to solve this problem, and processing recycled plastics into plastic particles is an important part of the plastic recycling industry. Traditional plastic particle production equipment has gradually exposed many shortcomings in the face of the growing demand for recycled plastic processing.

[0003] The feeding device of the existing plastic recycling granule production equipment is usually simple in structure. For recycled plastic products of various shapes and sizes, there is a lack of effective crushing and pretreatment methods. In the granulation process, the heating extrusion system of the traditional equipment has defects. On the one hand, the control of the heating temperature and the extrusion pressure is not precise enough, and it is difficult to ensure that the plastic is evenly softened and formed into regular plastic strips at the appropriate temperature and pressure. On the other hand, the cutting device and the discharge port are not tightly matched. When cutting the plastic strips into granules, it is easy to produce problems such as inconsistent particle size and uneven incision, which reduces the overall quality and market competitiveness of the plastic granules. Most existing cooling devices have a single cooling method, relying only on natural cooling or simple air cooling, and the cooling speed is slow, which reduces the production efficiency of the equipment and increases the production cost.
