Ⅰ. Product Overview

The PVC ceiling strip production line is an automated continuous production system that integrates raw material processing, extrusion molding, cooling and shaping, traction cutting and stacking packaging. This production line takes PVC resin as the main raw material. Through precise blending and high-temperature melt extrusion, the material is formed into a preform with specific decorative patterns through a specially designed mold. Subsequently, the parlet enters the vacuum shaping table for negative pressure adsorption and circulating water cooling, quickly fixing the cross-sectional shape and obtaining a smooth surface. It is then stably conveyed to the CNC cutting unit by a multi-segment synchronous traction machine and precisely cut to the set length. Finally, the sorting and packaging are completed through the automatic stacking device. The entire line adopts an intelligent control system to achieve closed-loop regulation of process parameters. It features low energy consumption, stable operation, low noise, and high yield rate. It can efficiently produce moisture-proof, fire-resistant, and diverse styles of PVC decorative lines, which are widely used in indoor and outdoor ceiling and wall decoration projects.

Ⅱ. MACHINE FEATURES

1. Conical Twin Screw Extruder:
This advanced extruder employs specially engineered screw profiles tailored to different polymer formulations, ensuring thorough and homogeneous micro-foam melt plasticization while delivering high-output, stable extrusion performance. Driven by internationally renowned AC frequency converters, it maintains precise and consistent rotational speed, enabling seamless synchronization between the main extruder and downstream auxiliary equipment for continuous, high-quality production.

2. Vacuum Calibrating Table:
Equipped with a high-capacity turbo cooling system, this unit provides rapid and uniform heat dissipation to achieve optimal dimensional stability and surface finish. Designed with modular flexibility, the vacuum calibrating table is available in customizable lengths—such as 4m or 6m configurations—to accommodate diverse mold specifications and meet specific customer requirements for product geometry and cooling efficiency.

3. Tractor Machine:
Incorporating a specialized lifting mechanism, this haul-off unit ensures smooth and steady material traction throughout the production process. Engineered for durability and operational reliability, it delivers strong, consistent pulling force while maintaining precise alignment with the extruder output, thereby preventing deformation or tension-related defects in the final product.

4. Cutting Machine:
The cutting system features fully synchronized movement with the haul-off unit, enabling accurate and clean cuts at preset lengths through automated control. Integrated with an efficient dust collection and recycling device, it maintains a clean working environment while minimizing material waste, supporting both productivity and workplace safety in continuous operation.

Ⅲ. Features and Advantages

This production line integrates multiple high-end configurations and innovative designs, meeting the demands of large-scale production with outstanding performance and efficient economy. Its core drive adopts ABB brand frequency converters to ensure stable and reliable operation throughout the full-speed range. The control circuit adopts Schneider brand contactors to ensure electrical safety during long-term and frequent start-stop operations. The temperature control system is equipped with Omron's high-precision PID temperature controller, achieving precise regulation within ±1℃ and significantly enhancing process stability.

In terms of energy efficiency, the production line has achieved a minimum comprehensive energy consumption of only 25 kilowatts per hour by optimizing the transmission design and thermal management strategy, which can save 25% to 30% of energy compared with similar equipment. The dedicated PVC ceiling strip screw equipped, combined with the intelligent infrared tracking flow stabilizing device, effectively solves the problem of extrusion flow fluctuation, enabling the addition amount of calcium carbonate filler to reach up to 300 parts per 100 parts of resin (300 PHR), significantly reducing the cost of raw material formula.

This production line features high speed and high output. Its production efficiency can reach more than twice that of ordinary WPC/PE profile production lines, while simultaneously reducing the comprehensive costs of labor, electricity and management. The extrusion speed and traction speed are coordinated and regulated by ABB frequency converters to achieve power optimization and convenient speed regulation. The online heat transfer unit supports the immediate formation of surface patterns, further simplifying the subsequent processes. While achieving highly automated operation, the entire machine maintains an excellent economic positioning, making it particularly suitable for large-scale investment and continuous production scenarios.

Ⅳ. Production Line Flow

This production line adopts a full-process integrated design. Starting from raw material preparation, it achieves precise measurement and high-speed mixing of PVC resin, fillers and additives through an automatic mixing system, and then enters the conical twin-screw extruder through vacuum feeding. Under the action of the screw structure specially optimized for PVC ceiling strips and the multi-stage temperature control system, the materials are fully plasticized and microfoamed to achieve homogenization. 

Then, they are extruded into shape through the flat die head and enter the vacuum shaping table for negative pressure cooling and shaping. Subsequently, the profiles are smoothly conveyed to the CNC cutting unit through a synchronous traction machine for fixed-length cutting, and can be integrated with online printing or hot stamping decoration processes as required. 

The final product is packaged after being automatically stacked and organized. The entire line adopts core components of international brands such as ABB, Schneider, and Omron, combined with infrared tracking flow stabilization and PID intelligent temperature control technology. While achieving a packing ratio of up to 300 parts, it maintains an ultra-low energy consumption of at least 25 kilowatts per hour, saving 25% to 30% energy compared to traditional production lines and increasing production efficiency by more than double. It has truly achieved an organic combination of high stability, low production cost and large-scale continuous production.
