Q: 1. What should I do if the paper feed belt frequently misaligns?

Possible causes and solutions: Uneven belt tension: Adjust both tensioning devices to ensure consistent belt tightness. Worn or sticky rollers: Clean or replace worn rollers to maintain a smooth surface. Aged or deformed belt: Inspect the belt for wear or stretching and replace promptly. Uneven equipment installation: Calibrate the equipment base using a level to ensure overall flatness.

Q: 2.How to select the appropriate paper feed belt material? What are the differences between various materials?

Polyurethane (PU) belts: Wear-resistant and anti-static, but prone to slippage. Rubber belts: High friction, low cost, suitable for standard cartons at medium to low speeds. Silicone belts: Higher cost, heat-resistant and anti-adhesive, ideal for UV printing or special coated papers. Selection Recommendations: Choose based on paper type (e.g., cardstock, corrugated paper), workshop environment (humidity, temperature), and equipment speed. Consult Yonghang for sample testing.

Q: 3.How to resolve paper feeding issues caused by slippage on the paper feed belt surface?

Clean the belt and rollers: Use alcohol to remove ink, dust, or adhesive residue from the belt surface. Increase friction: Replace with a textured belt (e.g., PJ-grooved paper feed belt) or apply anti-slip coating spray (ensure it does not affect paper quality). Adjust tension: Appropriately increase tension to avoid belts being too loose or too tight. Check paper weight: Lightweight or slippery paper requires auxiliary suction devices. (e.g., belt perforation suction to prevent paper from floating)

Question 4

4.How long is the service life of a rubber Feed Belt? What operations shorten its lifespan?

Accepted Answer

Normal lifespan: Under daily 8-hour working conditions, high-quality belts can last 1-3 years, depending on usage frequency and maintenance.

Operations that shorten lifespan:

- Prolonged operation of high-speed equipment beyond rated capacity;

- Exposure to corrosive cleaning agents or sharp objects;

- Excessively high ambient temperature and humidity (accelerates aging);

- Excessive tension causing stretching and deformation.

Maintenance Recommendations: Regularly clean the belt, avoid prolonged exposure to direct sunlight, and release tension when the machine is idle.

Question 5

5.What should I do if I encounter any quality issues?

Accepted Answer

We not only conduct quality inspections before shipment but also offer one year of after-sales service. Typically, one-piece vulcanized rubber belts can last over a year, while other synchronous(timing belts come with a three-month warranty. Should any quality issues arise, please contact us anytime for resolution.
