Abstract
The utility model relates to a roller structure which is designed for concave and convex special-shaped rubber belts. The roller comprises a roller body (1) and a roller shaft (2); the roller body is fixedly arranged on the roller shaft; and both ends of the roller shaft are respectively provided with a bearing seat (4). The roller is characterized in that both ends of the surface of the roller body adopt cast rubber structural bodies (5); the middle of the surface of the roller body adopts a wear resistant steel plate (6); the wear resistant steel plate (6) is cut into a plurality of circular arc plates according to the size of the periphery of the roller body and are uniformly distributed and welded on the surface of the roller body; and a plug welding hole is processed in the wear resistant steel plate. According to the utility model, the both ends of the surface of the roller body adopt the cast rubber, the middle of the surface of the roller body adopts the wear resistant steel plate, the both ends of the surface of the roller body are in plane contact with the concave or convex pattern rubber belt so as to increase a friction force, and the wear resistant steel plate in the middle is in contact with the pattern region of the pattern rubber belt, and thus, the service life of the rubber belt can be effectively prolonged. The roller is reasonably designed and is simple to manufacture; when the service life of the rubber belt is prolonged, the integral operation quality of a rubber belt conveyor is improved and the maintenance and repair workload of equipment is reduced; and the roller is reliable to operate and is economical and practical.
Description
Technical field
The utility model relates to a kind of roller frame, particularly relates to a kind of for indent, evagination Special-shaped adhesive tape and a kind of roller frame that designs is equally applicable to normal tape.
Background technology
Belt conveyer is widely used in the industry-by-industry of the every field such as coal, chemical industry, electric power, building materials.The cylinder that adhesive tape relies on operation is for larger impact is arranged in service life of adhesive tape.Especially for indent, evagination Special-shaped adhesive tape, the structure design of cylinder concerns the in-use performance of conveyer especially.Present cylinder surface adopts the casting plastic structure usually, although can effectively increase the friction force between adhesive tape and cylinder, not wear-resisting, easily damage, affect belt work life, be unfavorable for the overall operation of belt conveyer.
Summary of the invention
The utility model is not enough for prior art, proposes a kind of improved roller frame, can effectively extend the service life of adhesive tape.
The technical scheme that the utility model adopts:
The utility model cylinder mainly is comprised of parts such as cylindrical shell, expansion set, axle, bearing seats.Cylinder surface two ends employing casting glue, the middle wear-resisting steel plate that adopts, two ends and concave or convex formula patterned rubber belt plane contact increase friction force, and middle wear-resisting steel plate contacts with the patterned rubber belt decorative pattern is regional.
The casting glue at cylinder two ends is with general casting rubber cylinder, and the wear-resisting steel plate of centre portion is to cut into the uniform drum surface that is welded in of several arc plates according to circumferential size, can make several plug welding holes according to actual size on wear-resisting steel plate.Supposing that roller tube is long is L, and in patterned rubber belt, the decorative pattern width is l, roller tube surface abrasion resistance steel plate width L1 〉=l, and two ends casting glue width is (L-L1)/2 left and right.
The beneficial effects of the utility model:
1, the utility model roller frame, casting glue, the middle wear-resisting steel plate that adopts are adopted in the drum surface two ends, two ends and concave or convex formula patterned rubber belt plane contact increase friction force, and middle wear-resisting steel plate contacts with the patterned rubber belt decorative pattern is regional, can effectively extend belt work life.
2, the utility model roller frame, reasonable in design, makes simply, when extending belt work life, improved the overall operation quality of travelling apron, reduced the equipment maintenance work capacity, and is reliable, economical and practical.
Description of drawings

Fig. 2: the cross-sectional structural representation of the utility model cylinder (in Fig. 1, A-A is to analysing and observe).
The specific embodiment
Embodiment one: referring to Fig. 1, Fig. 2, the utility model cylinder, comprise cylindrical shell 1, cylinder axle 2, cylindrical shell 1 and cylinder axle 2 fix, cylinder axle 2 two ends respectively are provided with bearing seat 4, and its improvement is: cylindrical shell 1 surperficial two ends employing casting plastic structure body 5, the middle wear-resisting steel plate 6 that adopts, described wear-resisting steel plate is to cut into the uniform drum surface that is welded in of several arc plates according to the cylindrical shell circumferential size, is manufactured with plug welding hole on wear-resisting steel plate.
Casting glue is adopted at the drum surface two ends, and travelling apron is in service, and two ends and concave or convex formula patterned rubber belt plane contact can increase friction force; In the middle of cylindrical shell, employing wear-resisting steel plate and patterned rubber belt decorative pattern zone contacts, thereby can effectively extend belt work life.
Embodiment two: referring to Fig. 1, Fig. 2, the described cylinder of the present embodiment, what they were different from embodiment one is: long at the hypothesis cylindrical shell is L, and in patterned rubber belt, the decorative pattern width is in the situation of l, width L1 〉=the l of drum surface wear-resisting steel plate, cylindrical shell two ends casting plastic structure body width is (L-L1)/2.
Described cylinder, be provided with expansion set 3 at cylinder axle and cylindrical shell joint portion, seal ring 7, described cylindrical shell fixes with the cylinder axle by expansion set 3 and seal ring 7, and coordinate with described expansion set and a cylinder axle at the outer face of expansion set 3 outside cylindrical shells to be provided with annular baffle 8, described annular baffle 8 fixes by bolt and packing ring and cylindrical shell.
Claims (3)
