Abstract
The utility model discloses a kind of expanding roller, comprise central shaft and sheathed roller on center shaft, described central shaft is curved, and described roller is established on center shaft by bearing holder (housing, cover), and described roller quantity is odd number.The utility model makes expanding roller greatly extend service life, and ensures the fluency that roller rotates, the phenomenons such as when avoiding occurring cloth, cloth cover parallel is crooked, tension force is unstable, ensures the normal operation of producing.
Description
Technical field
The utility model relates to mechanical field, particularly, relates to a kind of expanding roller.
Background technology
Existing expanding roller is comparatively large because roller and between centers rub, and long-time friction all impacts central shaft and roller, and the friction of roller glue face is comparatively large, can cause the phenomenons such as cloth cover parallel is crooked, tension force is unstable, and expanding roller is shorter for service life when crossing cloth.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of expanding roller, and expanding roller is extended service life greatly, and ensures the fluency that roller rotates, the phenomenons such as when avoiding occurring cloth, cloth cover parallel is crooked, tension force is unstable, ensure the normal operation of producing.
For solving the problem, the technical scheme that the utility model adopts is as follows:
Expanding roller, comprise central shaft and sheathed roller on center shaft, described central shaft is curved, and described roller is established on center shaft by bearing holder (housing, cover), and described roller quantity is odd number.
Preferably, described roller two ends are provided with bearing, and described bearing fixing sleeve is established on center shaft.
Preferably, described roller quantity is 11.
Preferably, described roller external diameter is 80-90cm.
Compared to existing technology, the beneficial effects of the utility model are: the book setting of novel middle (center) bearing makes expanding roller greatly extend service life, and ensure the fluency that roller rotates, the phenomenons such as when avoiding occurring cloth, cloth cover parallel is crooked, tension force is unstable, ensure the normal operation of producing; The setting of central shaft radian, each roller stressed even when ensureing cloth; Being fixedly installed of bearing, ensures the stability of roller position on center shaft.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model longitudinal sectional view;
Wherein, axle, 2 is roller, 3 centered by 1 is bearing.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
