The straight tracking of the belt may be compromised by the type of conveyed material, especially when this material is sticky and thereby adheres easily to the belt surface.
In this case, material is also deposited on the return rollers that support the belt, adding an irregular addition of scale to the roller itself.
As a consequence, not only wear and tear of the belt occurs, but forces are brought into play to move the belt away from its correct track.
Return rollers with spaced rubber rings contribute largely to eliminating the build up of scale that forms in certain conditions on the belt surface.
The rings are pointed, assembled at intervals, in the central part of the roller, where they have the scope to break up the scale which normally is present at the belt centre; meanwhile flat rings mounted in groups at the extremities of the belt, support and protect the belt edges, also in cases of limited belt wandering.
Joyroll roller use high precision ERW welded steel pipe from famous brand pipe manufacturers, steel pipe ovality directly affect the radial runout of rollers and the rotating friction resistance, the inside and outside burr will effect the roller dynamic and static balance. The pipe we choose are special pipe just for roller, with small straigthness, small out of roundness, uniform wall thickness, and removing inside and outside deburring of pipe, its quality is higher than the national standard GB/T 13792-13792. The roller body is cut by fully automatic CNC cutting machine, ensure that the length of the roller body with high precision and small tolerance, and after shot blasting cleaning machine, to ensure that the coating adhesion, automotive pipe double end hole boring machine guarantee the roller concentricity.
Shaft is one of a major part of the roller, Joyroll rollers are all made of the high precision cold-drawn round bar, has good corrosion resistance, high strength and hardness, guarantee the quality and the service life of the roller. Chamfering and circlip groove are machined by CNC lathe, precise positioning of circlip groove effectively reduces the roller axial movement.
Bearing house is made of high quality cold-rolled steel plate, finished after many stamping molding, high precision, smooth and no burr, tolerance standard ISO M7. Bearing house and steel pipe welded together by special welding equipment, welding ends at the same time, guarantee the concentricity of roller, and matches by the Japanese panasonic welder, welding high strength, beautiful welding seam.
Bearing is the heart of the roller, high quality bearing can improve the roller service life. Our company all adopt domestic famous brand deep groove ball bearings with large clearance, also can choose a higher quality imported bearings. The bearing double seal, dust-proof and water-proof. Fill the lithium base grease, continued lubrication, maintenance free, working condition -40°C to 180°C.
Joyroll roller use the non-contact labyrinth seal structure, a complex formed between inner and outer seals, bending, precision of labyrinth channel, the material of sealing is nylon 6 or POM, and filled with high quality lithium grease, dustproof and waterproof.
