Two Tips of Corrugated Sun Wheel

Usually, the corrugated sun wheel will be manufactured from polyurethane and rubber, each possessing unique characteristics. Specifically, polyurethane (PU) sun wheels offer exceptional durability and abrasion resistance, making them particularly suitable for environments involving high chemical corrosion. Rubber sun wheels excel in noise reduction and shock absorption, rendering them especially well suited for use on uneven surfaces. You can select the suitable material for the leading paper feeding wheel (corrugated sun wheel) according to your actual corrugator carbon manufacturing conditions.

Apart from the material and types of corrugated sun wheel (like standard sun wheel, and sun wheel with bearing house or seat), it’s also important for you to choose the suitable sun wheel hardness, which determines the tightness of the fit between the sun wheel and the aluminum core. Excessive softness leads to accelerated wear, while excessive hardness can easily damage the corrugated sun wheel material, thereby hastening its aging (do not blindly pursue high hardness).

‍Installation and Inspection

Although Sunhong’s high quality corrugated sun wheels feature a carefully engineered hardness design that effectively resolves slippage issues during the paper feeding process of corrugators, while their smooth, bubble free, and burr free surfaces help prevent paper defects caused by excessive pressure from the no crush sun wheels, you must also remain mindful of other potential factors that could shorten the service life of these sun wheels or lead to their damage.

Firstly, the standardized installation procedure for the corrugated sun gear serves as the foundation for ensuring its stable, longterm operation.

• Ensure the tension is adjusted to the appropriate level to avoid overstretching the corrugated sun wheel.

• Ensure the correct installation orientation of the non-cursh sun wheel. Please install the corrugated sun wheel oriented in the direction of paper travel of the powered feeding line, and in the direction opposite to the corrugator paper travel of the non-powered line.

• Ensure directional consistency among all sun wheels located on the same shaft; otherwise, uneven pressure and tension will result in skewed or jammed paper.

Furthermore, to avoid a second shutdown, the paper feed test must be performed after the corrugated sun wheel installation. By performing a no load run, you can observe whether the paper feeds smoothly and check for any slipping, jamming, or misalignment.

• Skewed Paper Exit — Verify that the contact surface between the corrugated sun wheel and the cardboard is level; ensure no foreign objects are lodged in the mechanism.

• Lateral Drift — Ensure the sun wheel is installed horizontally and that the shaft is precisely aligned.

• Excessive Noise — Check for excessive tightness or looseness between the shaft and the bearing.

Regular inspection of the corrugated sun wheel is also essential.

• Ensure that the sun wheel operates smoothly and promptly remove any foreign objects.

• Select an appropriate lubricant based on the specific type recommended in the operating manual, and apply it to the corrugated sun wheel.

• Inspect the non crushing sun wheel for signs of wear; check its surface for scratches or cracks, and measure its thickness to verify uniformity. If the thickness has decreased by more than 10%, replacement is recommended.
