The key to the PET bottle recycling washing line machine is the removal rate of impurities. The impurities include environmental pollutants, other materials attached to the original plastic products, and heterogeneous substances. The higher the purity, the more high-quality products can be produced, and the lower the manufacturing cost and production loss of its products.
1. The drum screening machine ensures the separation of materials from other sundries: removing stones, wood chips, and small metals.
2. The stripper is mainly used to peel off the label paper on the surface of the PET bottle, especially the PVC or PS label applied on the PET bottle. Through the cooperation of the movable knife and the fixed knife, the label on the bottle body is peeled off together, and the difference between wind and gravity is used to separate the bottle body and the label, preserve the integrity of the bottle and the bottleneck, and reduce the loss of bottle top material.
3. The washing line is equipped with automatic material sorting machine and color sorting machine, which can greatly reduce the investment of human resources and greatly improve production efficiency, so as to truly realize a highly automated clean recycling production line.
4. The sorting system is the sorting and screening of the bottle body before crushing, screening out a small amount of foreign matter remaining in each unit at the front end (including heterogeneous bottles, heterochromatic bottles, a small amount of label scraps, metal reactants, garbage, etc.), and buffering The system is one of the means of large-capacity production adjustment, which is very important to the stability of process control. The location of its setting requires a deep understanding of the key points of the process. Manual sorting is a re-inspection and a way to ensure quality.
5. The crushing system adopts wear-resistant design to ensure the continuous operation of the system for a long time.
6. The hot cleaning effectively removes the residual glue, oil stains and some small impurities on the surface of the bottle flakes, which is very important to the life of the product filter assembly and product quality.
7. The high-speed centrifugal cleaning system applies the corresponding blade strike force to different materials at a suitable rotation speed to achieve the ideal cleaning effect.
8. The drum of the cleaning tank is designed for strong pressure underwater cleaning to remove residual impurities.
9. It can be equipped with corresponding centrifugal dehydration and hot air drying system according to the moisture content set by the production requirements.
10. The entire line is automatically controlled, and the units of the system are associated with each other, and it has a predictive function for possible abnormal situations.
