Fig. 1 is a schematic structural view of a nylon tension roller provided by an embodiment of the present invention.

Reference numerals:

1. a rolling body; 2. fixing a lock cap; 3. a carrier roller shaft.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail with reference to the accompanying drawings. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a nylon tension roller, including: the device comprises a rolling body 1, a roller carrier shaft 3, a fixed lock cap 2, a bearing seat, a bearing, a fixed pin and a support; the rolling body 1 is made of nylon 66, and the roller carrier shaft 3 is made of steel; the roller carrier shaft 3 comprises a first shaft body and a second shaft body, and the outer diameter of the first shaft body is larger than the inner diameter of the second shaft body; deep holes are formed in the middle parts of two ends of the rolling body 1, through holes are formed in the middle parts of the side surfaces of the rolling body, the inner diameters of the deep holes are larger than those of the through holes, and the inner diameters of the deep holes are larger than the outer diameter of the fixed lock cap 2; the first shaft body is arranged in the through hole in an interference fit mode, external threads are arranged at two ends of the first shaft body, and the roller carrier shaft 3 is fixed in the through hole of the rolling body through threaded connection by using a fixed lock cap 2; key grooves are formed in two ends of the first shaft body, fixing pins are arranged in the key grooves and are used for preventing the fixing lock cap 2 from loosening; the inner rings of the two bearings are respectively and coaxially sleeved at two ends of the second shaft body, the inner rings of the two bearings are coaxially sleeved on the two bearing seats, and the bearing seats are welded on the support.

Further, the bearing is a deep groove ball bearing.

The rolling body 1 is made of nylon 66, so that the belt can be prevented from being scratched by a carrier roller, the nylon 66 is stable in chemical performance, is not easy to react and deteriorate with the outside, and has a protective effect on the belt; the tensioning carrier roller is added on the loose edge of the belt conveyor, so that the initial tension of the belt conveyor is increased, and the driving wheel can obtain larger effective tension. The length of the carrier roller shaft 3 is between the width of the belt and the length of the support,

when the tension carrier roller is installed, the installation position of the tension carrier roller is properly adjusted so as to obtain enough initial tension, and simultaneously, the phenomenon that the friction force between the rolling body 1 and the belt is too large and generates heat to cause the belt to be seized with the rolling body 1 due to too large tension force of the belt is avoided.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
