System features

1. Positive-displacement conveying device can realize conveying and computing powder, easy centralized control, increasing degree of automation and satisfying requirements against environmental protection of modern enterprises. Our advanced IPC+PLC centralized control system allows operators to store complex formulations with a single click. This ensures full-link monitoring of the production process while providing real-time statistical analysis of energy consumption and material usage, empowering facility managers with actionable data to optimize daily operations.

2. Compact conformation, little space usage, tridimensional conveying direction. By utilizing a highly adaptable spatial footprint, this tube chain auto feeding conveying system integrates directly into existing facility layouts without requiring extensive structural modifications, preserving your valuable floor space for other critical machinery.

3. Flanges between inlet and outlet are airtight, then there is no need to install filter. When conveying powder, it can be feed in air and can assure that there is no dust spread into environment. This completely sealed design is crucial for maintaining a pristine workspace, protecting operators from airborne particulates, and minimizing material waste during transit from the storage silos to the extrusion lines.

4. Powder is conveyed smoothly along the lines almost with none inside movement; therefore, there is little dilapidation against materials, slow curve conveying make little material granule into scraps. Preserving the physical integrity of your PVC powder and sensitive additives ensures consistent extrusion performance and significantly reduces the rejection rate of the final manufactured plastic products.

5. According to different feeding conditions, distance between inlets can exceed 10m. This extensive reach provides exceptional flexibility for large-scale operations, allowing for the strategic placement of bulk bag unloading stations and dosing equipment far from the primary extruder if the plant layout dictates such an arrangement.

6. Chain wheel has been under hardening with minimum abrasion. The core silos and critical contact surfaces are constructed from industrial-grade stainless steel. Combined with these hardened chain wheels and specialized wear-resistant surface treatments, the system significantly reduces equipment wear, lowering long-term maintenance costs and extending the overall operational lifespan of the conveying network.

7. Special transfer dish with extremely low coefficient friction and stable delivery capacity. This ensures that even challenging or sticky materials flow consistently without bottlenecking, maintaining a steady, reliable feed rate to the PVC extruder for uninterrupted production cycles.

8. all our tube chain conveyors use our own computer program for different parts such as conveying line and curve parts to maintain necessary static friction and pullup and providing precise data to reach to low noise and little abrasion. The operational acoustic footprint is kept to an absolute minimum, creating a more comfortable and compliant auditory environment for plant workers who spend hours on the factory floor.

9. three dimension to convey: horizontal, inclining and vertical mix. This multi-directional capability eliminates the need for multiple independent transfer mechanisms, streamlining the entire material handling architecture into one cohesive, highly efficient network that navigates around existing infrastructure.

Advanced Dosing and Automated Unpacking

To complement the core conveying mechanism, the system is equipped with high-precision weighing sensors and an anti-bridging design, including pneumatic knockers and flow-assist air bowls. This guarantees that multiple powders and auxiliary materials are accurately measured and mixed according to exact formulations. Furthermore, we provide customized automated unpacking and feeding stations for bulk bags and standard 25KG sacks. These stations connect directly with the tube chain conveyor, establishing a dust-free, environmentally conscious workshop from the very source of material introduction.
