Description
Technical field
The utility model relates to technical field of mechanical equipment, and particularly a kind of photo-electric prevents the device of belt deviation.
Background technology
Belt deviation is the frequent produced problem of belt feeder.For preventing belt deviation, be generally provided with vertical roll type deviation switch at the two ends of belt.During belt deviation, belt touches the edger roll of deviation switch, and edger roll is deflected, and deviation switch carries out reporting to the police or shutting down according to the difference of edger roll deflection angle.Visible, vertical roll type deviation switch relies on belt directly to contact performance directive function with edger roll.
Belt and edger roll directly contact and must produce friction, when belt edge is impaired, can produces larger shock continuously by opposite roller, easily cause edger roll to damage.After edger roll damages, because edger roll and deviation switch are one, just have to change deviation switch.The frequent replacing of deviation switch not only increases the material cost of company, also increases maintenance maintenance work capacity.
Utility model content
The purpose of this utility model is that overcoming existing belt feeder deviation switch changes the defect frequent, maintenance maintenance work capacity is large, thus provides a kind of device without the need to frequently changing deviation switch.
To achieve these goals, the utility model provides the device that a kind of photo-electric prevents belt deviation, comprising: multiple photoelectric switch group, combined aural and visual alarm; Described multiple photoelectric switch group is arranged on multiple positions of the close belt of belt feeder respectively; Each position is provided with two photoelectric switch groups: the first photoelectric switch group and the second photoelectric switch group; Described first photoelectric switch group is between the edge line and the edge line of cylinder of belt, and it is connected with described combined aural and visual alarm; The line of centers of described second photoelectric switch group overlaps with the edge line of cylinder, and it is connected with the pull switch of belt feeder.
In technique scheme, the photoelectric switch in described photoelectric switch group and the plane at belt place are at a distance of 50mm ~ 100mm.
The utility model has the advantage of:
1, the utility model efficiently solves and prevents belt deviation from relying on deviation switch edger roll directly to contact with belt, rub at present, and the problem that the edger roll rapid wear produced, deviation switch are frequently changed.
2, the utility model utilize the limit function of photoelectric switch and spacing time the characteristic that directly do not contact with belt; the position of originally installing vertical roll type deviation switch at belt feeder installs two groups of photoelectric switchs side by side; and connect combined aural and visual alarm and pull switch respectively; while realizing the warning of belt deviation two-stage, shutdown effect; owing to there is no direct contact friction; damage can not be caused to photoelectric switch and belt, thus greatly save Master Cost and the manual maintenance expense of company.

Detailed description of the invention
Now the utility model will be further described by reference to the accompanying drawings.
With reference to figure 1 and Fig. 2, photo-electric of the present utility model prevents the device of belt deviation from comprising: multiple photoelectric switch group, combined aural and visual alarm; Described multiple photoelectric switch group is arranged on multiple positions of belt feeder respectively, as belt feeder installs the position of vertical roll type deviation switch originally; Each position is provided with two photoelectric switch groups: the first photoelectric switch group 21 and the second photoelectric switch group 22; Described first photoelectric switch group 21 is between the edge line and the edge line of cylinder 1 of belt 3, and it is connected with combined aural and visual alarm; The line of centers of described second photoelectric switch group 22 overlaps with the edge line of cylinder 1, and it is connected with the pull switch of belt feeder.
Below the parts in device of the present utility model are described further.
The plane at the photoelectric switch in described photoelectric switch group and belt 3 place keeps certain distance, and as the preferred implementation of one, this distance is 50mm ~ 100mm.
Prevent in the device of belt deviation in photo-electric of the present utility model, two photoelectric switch groups in a position form the monitoring of two-stage sideslip to belt deviation.When belt deviation and when touching the photosignal that the first photoelectric switch group 21 sends, the combined aural and visual alarm that the first photoelectric switch group 21 connects starts to report to the police; When belt deviation is serious; first touch the photosignal that the first photoelectric switch group 21 sends; the combined aural and visual alarm that first photoelectric switch group 21 connects is reported to the police; touch the photosignal that the second photoelectric switch group 22 sends again; second photoelectric switch group 22 shutdown signal gives the pull switch of the belt feeder be connected, and belt feeder is shut down.
Device of the present utility model has good economic benefit, and before not using the utility model, a belt feeder changes deviation switch 20 group of-100 group every year.After using the utility model, need not change throughout the year.Remarkable in economical benefits.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted.Although be described in detail the utility model with reference to embodiment, those of ordinary skill in the art is to be understood that, the technical solution of the utility model is modified or equivalent replacement, do not depart from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
