A kind of be with steel pipe as roller roller skin, there is following problem in it: the one, support roller device is long and narrow face contact with contacting of adhesive tape, long-term use roller skin is easily worn out, make the roller skin with the axle decentraction, easy scratch adhesive tape, and adhesive tape accounts for the value of whole piece belt feeder nearly 1/3rd, loss is serious.The 2nd, the bearing felt of support roller device adopts the nylon 1010 seal ring to seal, and sealing property is not strong.At first, the sealed nylon circle can expand and shrink under the situation of being heated and catching a cold, and when expanded by heating, seal ring is in the swelling state with contacting of axle, makes seal ring be worn.When shrinking, produce the gap between the contact surface of seal ring and ram axle bearing and axle when catching a cold.The generation in gap causes the leakage of butter.Secondly, seal ring is to adopt labyrinth seal, can only prevent dust, can not waterproof, and glassware for drinking water has flowing power, can flow in the gap of seal ring, makes moisture can enter in the sealed chamber, on bearing, makes bearing generation corrosion.The leakage of butter and the corrosion of bearing cause bearing to rotate dumb and stuck phenomenon.Particularly use in the south of many high temperature, rainy water, it is impaired to make that more bearing quickens, and the roller skin is more easy to wear.The 3rd, roller skin itself does not possess the function of cleaning and aligning correction, belongs to consumable accessory.
Another kind is to utilize spring as the roller skin, as Chinese patent 200520052579.2 disclosed " the anti-deviation grooving support roller device of left-hand and right-hand spring ".This spring-loaded idler device in use spring is easy to generate fracture, its reason is: the inhomogeneous spring that makes of convey materials produces the breaking force repeatedly that lateral pressure, torsion and spring move back and forth simultaneously in the operation grooving, make spring be in the lateral deformation pressured state for a long time, produce metal fatigue, so that fracture easily.
Summary of the invention
It is good to the purpose of this invention is to provide a kind of resistance to abrasion, the permanent roller and the support roller device that are used for belt conveying equipment of long service life.
Realize that the technical scheme that above-mentioned purpose adopts is:
Permanent roller of the present invention comprises anchor shaft and by the cylindrical shell of bearing installation on anchor shaft, is fixed with wear-resisting spring on the surface of cylindrical shell.
Further:
The outer end of described cylindrical shell is provided with rib;
The sealing of described bearing is to adopt O RunddichtringO and outside framework oil seal to cooperate with the nylon 1010 seal ring between the anchor shaft at bearing two ends and bearing seat to carry out inside and outside sealing.
Support roller device of the present invention, comprise support, the roller group is housed on the support, the roller group is made up of the side roller that the middle roller and the bilateral symmetry of by-level setting is obliquely installed, each roller adopts the permanent roller of the invention described above, drum surface is fixed with wear-resisting spring respectively, is that the wear-resisting spring rotation direction on the side roller of described symmetry is opposite at least.
The present invention is owing to be fixed with wear-resisting spring on the surface of permanent roller cylindrical shell, the roller cylindrical shell contacts with belt by wear-resisting spring, their contact surface is significantly smaller than the contact surface of common support roller device cylindrical shell itself and belt, wear resisting property is for greatly improving, be common support roller device 50-70 doubly, the idler roll skin is difficult for worn out, and it is concentric to make that idler roll skin and axle remain, and is difficult for the scratch adhesive tape.The sealing of roller bearings is to adopt outside framework oil seal and O RunddichtringO to seal, and has well like this prevented entering of dust and water, and lubricating oil can not reveal yet, and has guaranteed the service life of bearing, has also prolonged the service life of support roller device.Because the outer end of roller tube is provided with rib, brings into operation from belt feeder and just well to have limited the impetus of belt deviation, thereby prevent the sideslip of belt.And the opposite wear-resisting spring of fixing on the roller cylindrical shell of rotation direction, the function that poly-middle correction is arranged and clean.
