Thermoplastic Elastomer Pelletizer with Efficient Debris Collection
During thermoplastic elastomer (TPE) pelletizing, traditional pelletizers tend to generate significant amounts of flying debris and dust, causing environmental pollution, operational hazards, and material waste. To address these issues, this project has developed a dedicated pelletizer that integrates efficient cutting with real-time debris collection, greatly improving material utilization and workplace cleanliness.
1. Project Background
During thermoplastic elastomer (TPE) pelletizing, traditional pelletizers tend to generate significant amounts of flying debris and dust, causing environmental pollution, operational hazards, and material waste. To address these issues, this project has developed a dedicated pelletizer that integrates efficient cutting with real-time debris collection, greatly improving material utilization and workplace cleanliness.
2. Equipment Design Features
Enclosed Cutting Chamber: Fully sealed design prevents debris scattering, with built-in suction ports for continuous dust and fragment collection.
Multi-Stage Separation System: Equipped with vibrating screens and cyclone separators to automatically separate pellets from debris, allowing collected scraps to be reused or processed centrally.
Intelligent Cutting Adjustment: Automatically adjusts blade speed and cutting distance based on TPE hardness and feed rate, ensuring pellet uniformity while minimizing excess debris.
Modular Easy-Clean Structure: Key contact components feature quick-disassembly design for easy cleaning and maintenance, preventing material residue and cross-contamination.
3. Key Technical Process
Feeding & Cutting: TPE strands are steadily conveyed into the cutting zone, where high-speed shearing is performed with low-temperature air cooling to reduce material sticking and thermal degradation.
Simultaneous Debris Collection: A negative pressure collection system activates during cutting, transporting debris via piping to a sealed dust container.
Pellet Screening & Packaging: Intact pellets are sorted through a vibrating screen into packaging units, while debris is automatically directed to a recycling bin, supporting closed-loop reprocessing.
4、Quality Control
Raw Material Quality Control
A strict supplier audit and raw material inspection system is established. All incoming polyethylene base resin, antibacterial agents, and modification additives are tested batch by batch. Key test indicators include Melt Flow Rate (MFR), density, effective content of antibacterial components, and limits for heavy metals and harmful substances. Only materials passing all criteria are released for production, ensuring consistency and safety from the source. Additionally, key additives (e.g., antibacterial masterbatch) undergo thermal stability testing during processing to prevent efficacy loss in subsequent high-temperature processing.
Process Quality Monitoring
Key monitoring points are set throughout the entire production process. During the compounding and pelletizing stage, temperatures, torque, and pressure in different zones of the twin-screw extruder are monitored online to ensure homogeneous dispersion of all components. In the injection molding stage, an intelligent sensor system tracks and provides real-time feedback on barrel temperature, injection pressure/speed, holding pressure, and mold temperature, ensuring process window stability. Core parameters are recorded every half hour, and the first-off appearance, dimensions, and weight of products are quickly checked every 100 cycles, enabling immediate warning and intervention for process anomalies.
