Maintenance Procedures For Aluminum Rollers

Aluminum guide rollers, also known as aluminum alloy guide rollers, are made of excellent aluminum alloy materials, which are suitable for printing, packaging, plastics, papermaking, fiberglass, pharmaceutical, electronic batteries, textiles and other machinery industries and various coil processing industries. Aluminum alloy guide rollers are also used in their respective printing work, and the aluminum guide roller products produced are all roller products like aluminum rollers. You can see at a glance the difference between aluminum rollers and mirror rollers. The higher the hardness, the better the quality. High hardness is often a prerequisite for durability.
In addition, the difference between mirror rollers and aluminum guide rollers is also reflected in the materials used to make them.
The molds are made of various specifications, and the tubular aluminum guide rollers have a high-strength stiffener structure. Precision equipment and special tools are used for surface finishing, so that the surface is smooth, the coaxiality reaches 0.02mm, the whole axis is balanced and corrected by the computer within 2g, and the special process of the shaft end of the aluminum guide roller of the packaging machine and the imported bearing make it easy to run at high speed. According to the different requirements of the industry, its surface can also be specially treated: sandblasting, anilox, Teflon and special hardening HV700, which makes it have good scratch resistance, wear resistance and long service life.
The customizable aluminum guide roller has the advantages of high strength, low resistance, light weight, flexible rotation, wear resistance and corrosion resistance, and bright stainless steel surface. It is especially suitable for printing, packaging, film, papermaking, medicine, plastics, electronic batteries and other precision machinery industries, as well as various coil processing industries.

The structure of aluminum guide rollers can be roughly divided into:
(1) Hollow aluminum roller: inner bearing structure, the bearing is installed in the bearing holes at both ends.
(2) Shaft aluminum roller: The two ends of the roller body are combined with the steel shaft or stainless steel shaft end to form an integrated structure.
(3) Aluminum roller with water: cooling or heating liquid enters and exits from both sides and circulates in the roller body.

Maintenance procedures and steps of aluminum guide rollers:
1) Aluminum guide roller glazing self-protection: remove the glass layer on the surface of the rubber roller to maintain superior surface roughness.
2) Aluminum guide roller decalcification self-protection: During the printing process, the hydrophilic function of the rubber roller often breaks out, resulting in serious water running and ink rolling of the ink roller, which is easy to lead to consequences when printing web. This is often caused by calcification of the rubber rollers. In printing, calcium comes from paper and water, and calcium is deposited on ink and water rollers every day. Therefore, calcium removal is an indispensable self-care process in printing.
3) Clean and comfortable color change of aluminum guide roller: in the process of color change from dark color to light color in printing and spot color printing, it is often clean and hard, and the color change time is long, which reduces the efficiency of the printing machine and forms the addition of scrap rate; Moreover, the unclean will accumulate on the rubber surface, increasing the surface roughness of the rubber roller. That's why we emphasize starting care every day, cleaning and cleaning every time. Maintenance of aluminum guide rollers: In order to prevent the influence of temperature on the rubber rollers and maintain the excellent shape of the rubber of the idler seat, special maintenance of the idler rollers is required.
4) Ink hardening and self-protection: the hard roller in printing is prone to dry ink accumulation in the case of frequent discoloration, and every time the ink roller is cleaned, because the hard roller is not as clean as the soft roller, it is necessary to clean the dead ink on the hard roller to prevent the hard roller from affecting the life of the soft roller and the color recovery.
5) Recovery of the current colloid: After the rubber roller is used for a period of time, it is necessary to restore the hardness and elasticity of the current rubber, and clean the impurities such as ink, paper powder, and paper wool accumulated on the rubber roller. The recycled rubber roller can have the printing performance of the new rubber roller.

Advantages of aluminum guide rollers:
1) The aluminum guide roller is extruded by excellent aluminum alloy, with nine stiffeners and a wall thickness of 5cm, which can play a reinforcing role. Surface treatments include ordinary oxidation, hard oxidation, PTFE, etc. According to the user's requirements, its rigidity and wear resistance are ensured. Advanced balancing and correction are introduced, enabling the balance to reach 2g. Using imported precision processing equipment, tools and measuring tools,
The surface roughness and coaxiality of the manufactured rolls can reach 0.8 and 0.02 mm, and the reasonable shaft head connection method can easily and freely operate, and it will not be deformed at any running speed. Aluminum guide rollers have the characteristics of high strength, low resistance, corrosion resistance, light weight, stable rotation and no rust.
2) The frosted surface of the aluminum guide roller is finished with precision equipment and special tools to make the surface smooth and the coaxiality reaches 0.02mm. The whole shaft is balanced and corrected by the computer within 2g, and the special process of the shaft end is matched with the imported bearing, so that it can run easily and at high speed.
Depending on the requirements of the industry, its surface can also be treated with special treatments: sandblasting, anilox, Teflon and special hardening treatments, which make it have good scratch resistance and abrasion resistance.
3) The aluminum guide roller and its processing technology, comprising a hollow aluminum tube matrix, wherein: the two ends of the aluminum tube matrix are provided with grooves, an aluminum block matching the size of the groove is arranged in the groove, the aluminum block is fixed in the groove, and the aluminum block is provided with a coaxial through hole with the aluminum tube base. According to the different requirements of strength, aluminum tube substrates with different inner diameters can be selected.
Since the overall strength of the aluminum guide roller is mainly guaranteed by the wall thickness of the aluminum block, the wall thickness of the aluminum tube matrix of the aluminum guide roller of the same strength will be thinner, so the weight is lighter and the material is saved.
