Screen changer for plasticized steel strapping lines

The screen changer is the core equipment for the production line of plastic steel strapping to realize efficient, stable and low-cost production. During the production of strapping, there may be some impurities in the plastic melt, such as incompletely melted plastic particles, dust, etc. The automatic screen changer can effectively filter out these impurities for the subsequent molding of strapping. The automatic screen changer can effectively filter out these impurities and provide clean, impurity-free plastic melt for the subsequent strapping molding process, thus ensuring the quality of the strapping with better strength, toughness and appearance quality.

Core Functions and Advantages

Impurity filtration and quality assurance

In the production of plastic steel strapping, the plastic melt may be mixed with unmelted particles, dust and other impurities. The screen changer intercepts the impurities through the precision screen to ensure the purity of the melt and avoid the problems of insufficient strength and surface defects caused by the impurities. For example, a screen changer with a dual-column, 4-chamber design can be flushed 100% automatically to continuously filter out impurities and improve the appearance and mechanical properties of the product.

Increased production stability and efficiency

The screen changer monitors the status of the screen in real time and triggers the screen changing mechanism automatically when it is clogged, avoiding production interruptions caused by the accumulation of impurities. For example, the PLC-controlled continuous backwashing screen changer can realize screen changing without stopping, ensuring continuous operation of the production line and increasing production efficiency by more than 20%.

Automation and Intelligent Control

Modern screen changers are equipped with an intelligent control system that can preset screen changing parameters (e.g., pressure thresholds, time intervals) to realize fully automatic operation. For example, the automatic mesh changer moves the mesh belt through the melt pressure without the need for an additional power unit, reducing manual intervention and the risk of operational errors.

Energy Saving and Environmentally Friendly Design

The powerless screen changer design utilizes the melt's own pressure to drive the screen changer, which reduces energy consumption; the water-cooled sealing technology prevents material leakage and reduces raw material waste. For example, by optimizing the structure of a certain type of screen changer, energy consumption is reduced by 15% compared with traditional equipment, while avoiding environmental pollution in production.

Automatic screen changer is suitable for the production of baling tape of many plastic raw materials, such as PP, PE, etc. It can also be applied to the production process of baling tape of different specifications and types, with strong versatility and adaptability. It has significant advantages in improving production efficiency, ensuring product quality and reducing maintenance costs, etc. It is an indispensable and important equipment for modernized baling band production.
