Description

A kind of anti-deviation head roll for belt feeder

Technical field

The utility model relates to a kind of head roll, belongs to load transfer device field.

Background technology

Existing head roll adopts cylindrical design, and belt feeder often occurs the phenomenon of sideslip and not easily regulates in the process of running, causes the damage that belt is often subject in various degree, reduces the service life of belt, increase productive costs.

Summary of the invention

The purpose of this utility model is: provide a kind of anti-deviation head roll for belt feeder, cylindrical design is adopted to solve existing head roll, the phenomenon of sideslip is often there is and not easily regulates in belt feeder in the process of running, cause the damage that belt is often subject in various degree, reduce the service life of belt, increase the problem of productive costs.

Scheme of the present utility model is as follows: a kind of anti-deviation head roll for belt feeder, comprise head roll body, the surperficial car of described head roll body has decorative pattern, and head roll body is drum organization, and the diameter in the middle of head roll body is greater than the diameter at two ends.

The tapering of described head roll body is 0.5 °.

The decorative pattern of described head roll body surface is the screw-type decorative pattern gone out along the circumferencial direction car of head roll body.

Along head roll body circumferencial direction at least car have two screw-type decorative patterns.

Circumferencial direction car along head roll body has two screw-type decorative patterns, and two screw-type decorative patterns are uniformly distributed along the length direction of head roll body.

The utility model compared with prior art, major advantage is drum organization by head roll body design, effectively prevent belt deviation, simultaneously at head roll surface car decorative pattern, while increase belt drive friction force, also effectively play the effect of deviation rectifying leather belt, prevent belt deviation further, increase belt service life, cost-saving.

Accompanying drawing explanation

Fig. 1 is main TV structure schematic diagram of the present utility model.

Detailed description of the invention

For making the technical solution of the utility model more clear, below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail,

With reference to Fig. 1, a kind of anti-deviation head roll for belt feeder is provided, comprises:

Head roll body 1, the surperficial car of described head roll body 1 has decorative pattern 2, and head roll body 1 is drum organization, and the diameter in the middle of head roll body 1 is greater than the diameter at two ends.

Preferably, the tapering of head roll body 1 is 0.5 °.

Preferably, the decorative pattern 2 on head roll body 1 surface is the screw-type decorative pattern gone out along the circumferencial direction car of head roll body 1.

Further preferably, along head roll body 1 circumferencial direction at least car have two screw-type decorative patterns.

Further preferably, circumferencial direction car along head roll body 1 has two screw-type decorative patterns, and two screw-type decorative patterns are uniformly distributed along the length direction of head roll body 1, setting like this, while increasing the driving friction force that belt is subject to, the driving friction force that belt is subject to is comparatively even, and belt is sideslip not easily.
