III. Equipment Working Process

Lightweight materials such as waste EPE pearl cotton, bubble films and foam scraps are automatically and uniformly fed by a 5-meter extended and 800mm widened PVC conveyor belt, stably transporting fluffy materials to the feeding port. Then the materials enter the forced feeder, where the 11KW power and thickened feeding teeth compact and push the materials at a constant speed, completely solving the problem of light material slipping and idling. The materials enter the main machine of the 377-150 EPE pearl cotton pelletizer, where the 377mm large-diameter compression structure compacts and exhausts the materials, and the high-frequency heat-treated screw and barrel of the main machine complete the first melting and plasticization. The 60KW electromagnetic heating and four groups of independent heating rings perform segmented constant temperature control throughout the process to ensure full and uniform material melting. The initially melted melt enters the 150-type auxiliary machine for secondary refining and homogenization, and the 380mm mesh machine head effectively filters fine impurities and stabilizes discharging pressure. Finally, uniform material strips are extruded, and high-quality recycled particles with regular appearance and qualified purity are produced after cooling, air drying, pelletizing and screening. The whole process operates automatically and linkage without multi-person duty.

1. FAQ

Q1: Do large pieces of whole pearl cotton need to be torn and crushed in advance?

A: No need. The 377-150 EPE pearl cotton pelletizer is equipped with a large-diameter compression feeding structure and forced feeding system, which can directly feed whole, large and stacked fluffy pearl cotton materials without pre-cutting, tearing or pretreatment. It saves the investment of front-end crushing equipment, simplifies the production line process, and reduces labor costs and equipment occupation space.

Q2: Why are pearl cotton particles made by ordinary pelletizers prone to bubbling and hollowing?

A: Pearl cotton is extremely light and fluffy with large internal gaps. Ordinary equipment has no large-diameter compression and compaction structure, so materials wrap a lot of air during feeding. In addition, single temperature control and short plasticization time lead to unremoved air, resulting in hollowing, bubbling and holes after cooling. In contrast, this equipment adopts the process of front forced compaction and exhaust + two-stage extrusion + multi-section temperature control, which can fully discharge internal air of materials and realize thorough plasticization, producing full and dense finished particles.

Q3: Is the equipment prone to wear and failure during long-term continuous production?

A: No. The core spiral blades, screws and barrels are all made of high-frequency heat-treated reinforced materials, with hardness and wear resistance far exceeding ordinary accessories. Matched with thickened frame and stainless steel protective structure for dust and slag prevention, the equipment operates stably. With normal maintenance, it can realize 24-hour uninterrupted mass production for a long time with extremely low failure rate and low operation and maintenance costs.
