Trapezoidal Roofing sheet rool forming machine is a common type among tile-making machines. After being roll-formed, the surface of the trapezoidal color steel tile is galvanized and coated with a colored layer, which not only provides anti-corrosion performance but also has a certain decorative effect. Its wave shape is trapezoidal, with right angles or approximately right angles formed between adjacent wave crests and troughs, which is significantly different from arc-shaped color steel tiles.The trapezoidal design can enhance the structural strength of the sheet itself. The width of the material is approximately 914-1450mm, and the thickness usually ranges from 0.3mm to 0.8mm.
Trapezoidal roof tile making machine adopts a split-type forming process, and is equipped with a film coating device at the feeding port. This combined design has clear pertinence and optimization value in terms of technical implementation and practical application. Among them, the split-type forming process decomposes the traditional integrated roll forming process into multiple independently operating modules to complete step by step. Specifically, each step-by-step roll forming unit of the equipment is responsible for specific links in the forming process of the trapezoidal cross-section, such as pre-bending, edge folding or shaping. Through such step-by-step operations, it is possible to flexibly adjust parameters such as the roll forming angle and pressure of each module, so as to adapt to the production needs of trapezoidal color steel tiles with different specifications of wave height, wave distance and plate thickness. It not only reduces the overall equipment debugging time caused by product specification switching, but also avoids problems such as wrinkling and cracking of the plate during the forming process by dispersing the roll forming stress. At the same time, the independent design of a single module also facilitates later maintenance and replacement, reduces the overall failure rate of the equipment, and is especially suitable for small-batch and multi-specification customized production scenarios.
The film coating device installed at the feeding port works as follows: when the steel plate enters the equipment from the unwinding rack, the film coating device will synchronously attach the protective film (mostly PE film or composite film) tightly to the surface of the plate through the pressing roller. Since the film coating operation is completed before forming, it can effectively prevent the surface coating of the plate from being scratched or stained due to friction and extrusion during subsequent roll forming and handling. This is particularly important for color-coated steel plates with high decorative requirements. Meanwhile, the device is equipped with a tension control system, which can accurately adjust the pressure according to the thickness of the plate and the material of the protective film, ensuring that the film coating process is smooth without bubbles or deviation, and will not affect the flatness of the base material and the subsequent forming accuracy.
From the perspective of production, this combined design of split forming and feeding port film coating not only enhances the equipment's adaptability to multi-specification products, but also reduces the subsequent processes of manual decontamination and repair through the film coating link, improving the overall production efficiency. From the perspective of products, the step-by-step forming ensures the structural accuracy of the trapezoidal cross-section, such as the verticality of wave crests and the flatness of wave troughs, while the pre-coating film prolongs the surface integrity of the products during storage and transportation. Ultimately, it achieves a dual improvement in production flexibility and product quality protection.
Trapezoidal roof sheet rool forming machine adopts a arch structure, and its components are connected with nuts to ensure greater stability during the operation of the machine. The speed of the stand structure is approximately 25-40 meters per minute.
Trapezoidal Roofing sheet rool forming machine adopts a stand-type structure, and all components are connected with high-strength nuts. This connection method can significantly improve the overall structural stability of the equipment, effectively suppressing vibration and displacement caused by rolling force during operation, and ensuring uniform force on the plates and stable dimensional accuracy in the forming process. Regarding the operating speed of the equipment, it is approximately 25-40 meters per minute. This speed parameter is coordinated with the stability of the stand structure - the stable machine body reduces production interruptions caused by vibration, providing a basic guarantee for continuous and efficient forming processing.
Trapezoidal roof tile making machine is also equipped with a servo tracking cutting structure. This structure, relying on the precise positioning and dynamic response capabilities of the servo system, can complete the cutting operation of the formed color steel tiles while the equipment is continuously running. Its core feature is that when the cutting mechanism performs the cutting action, the main forming machine does not need to stop and remains in a stable operating state.
This design, through the real-time position tracking and speed matching of the servo motor, ensures that the cutting action is completely synchronized with the conveying speed and forming rhythm of the color steel tiles. It not only avoids production interruptions caused by stopping for cutting, reduces energy loss and mechanical impact from equipment start-ups and shutdowns, but also significantly improves overall production efficiency. At the same time, it ensures the flatness and dimensional accuracy of the cutting edges, making it particularly suitable for large-scale production scenarios with high requirements for production capacity and processing consistency.
