Aluminum guide rollers are devices used in industrial production to guide and support the movement of materials or products. The following is an introduction to the basic use of aluminum guide rollers:
1) Installation position selection: First, determine the installation position of the aluminum guide roller to ensure that its position is appropriate and meets the process requirements. Typically, aluminium guide rollers are installed at the turn of the conveyor line or where the material needs to be guided.
2) Installation and fixation: Fix the aluminum guide roller in the appropriate position, usually by bolts or other fixing devices to install it on the bracket of the conveyor line or machine. Make sure the installation is secure and avoid shaking or shifting during use.
3) Adjust the angle and position: Adjust the angle and position of the aluminum guide roller according to the actual needs to ensure that it can accurately guide the material or product. In general, the angle of the aluminum guide roller should match the direction of the conveyor line and be appropriately away from the movement path of the material or product.
4) Keep it clean: Regularly inspect and clean the aluminum guide rollers to make sure there is no accumulation of debris or dirt on their surface. Cleaning maintains the smoothness of the surface of the guide rollers, reduces frictional resistance, and prolongs service life.
5) Regular lubrication: Regular lubrication is carried out on the bearings or rolling parts of the aluminum guide rollers as needed to ensure their normal operation and reduce friction loss. Choose the appropriate lubricant and lubricate it according to the manufacturer's recommendations.
6) Monitor the operation: regularly check the operation of the aluminum guide roller, including whether the bearing is normal, whether the guide roller has abnormal noise or vibration, etc. Identify and address problems in a timely manner to avoid failures that impact production.
7) Pay attention to the operation: When using the aluminum guide roller, pay attention to the operation to avoid fingers or clothing being caught in the guide roller to avoid injury. At the same time, make sure that there is no debris accumulation around the guide rollers for proper operation.

Maintenance measures for aluminum guide rollers:
1) Aluminum alloy guide roller varnishing maintenance: remove the glass layer on the surface of the rubber roller to maintain good surface roughness.
2) Decalcification maintenance of aluminum guide roller: During the printing process, the hydrophilicity and ink absorption of rubber roller often decrease, resulting in serious water and ink ingress of the ink roller. It is easy to cause problems in the printing field and the silk screen, which is often caused by the calcification of the rubber roller. In printing, calcium comes from paper and water, and calcium is constantly deposited on ink and water rollers every day. Therefore, decalcification is an essential maintenance procedure in printing.
3) Cleaning and maintenance of aluminum alloy guide roller discoloration: during the printing process, when the dark color changes to light color and the spot color changes, it is often difficult to clean, and the discoloration time is long, which reduces the efficiency of the printing machine and increases the rejection rate; And if it is not cleaned, it will accumulate on the rubber surface, reducing the surface roughness of the rubber roller. Therefore, we emphasize that maintenance should start every day, and every cleaning must be cleaned.
4) Aluminum guide roller idling maintenance: In order to prevent the influence of temperature on the rubber roller and keep the rubber of the idle seat in good condition, the dry running ink roller needs special care and maintenance.
