Maintenance and Care Precautions for Stone Paving Rubber Rollers
Rubber rollers are widely used in textile, papermaking, leather, packaging and other equipment for pressing rubber rollers, as well as in industries such as metallurgy, mining, printing, dyeing, chemical fiber, and papermaking for traction rubber rollers. They have excellent elasticity and mechanical strength, and good alkali resistance. Since the internal structure of newly cast rubber rollers is not yet stable, using them immediately can easily reduce their lifespan. Therefore, the maintenance of Shipa rubber rollers is very important. Below are the precautions to take during use:
1. Before Printing
Check for foreign objects between the rollers, ensure the rubber rollers are intact, and that the pressure between the rollers is uniform and consistent. Confirm normal conditions and clean thoroughly before proceeding with printing.
2. During Printing
Shipa rubber rollers should always maintain good contact during operation, with uniform and consistent force. Regardless of the width of the printed product, the entire rubber surface of the roller should be lubricated with ink oil; depending on the amount of ink accumulation between the rollers, the ink volume should be adjusted in a timely manner to ensure printing quality.
To prevent the ink from drying too quickly, which would reduce the viscosity of the rubber rollers and cause skin formation on the surface, the amount of drying oil added to the ink should be controlled to prevent issues with ink transfer and uneven ink application during operation.
3. After Printing
Timely separate the rollers from each other and from the printing plate to relieve pressure and prevent deformation of the rubber surface due to static pressure. Clean the residual ink from the surface of the rubber rollers promptly to prevent drying, which can lead to ink clumps, ink films, and dirt floating on the rubber surface (especially ink clumps on both ends of the nylon rollers), which can damage the smoothness of the rubber surface during operation, and in severe cases, cause pitting and flaking.
4. Cleaning the Rubber Rollers
Shipa rubber rollers must be cleaned with a special cleaning agent before and after printing to maintain a smooth surface for future use.
If cleaning is not done in a timely manner, ink can adhere to the micro-pores on the surface of the rubber rollers, trapping paper fibers and dirt. If the downtime is too long, the ink film can cause the contact surfaces of the two rollers to stick together, and when restarted, it can tear the rubber surface, rendering the rubber roller unusable.
Inadequate cleaning can lead to glazing, which reduces ink affinity and transfer capability, and can even cause ink removal issues. Glazing increases the hardness of the rubber roller surface, decreases elasticity, and accelerates wear, leading to pitting and cracking on the rubber surface, causing flaking and affecting printing quality.
