Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below In conjunction with specific implementation mode, the utility model is expanded on further.

As shown in Figure 1, carrier band conveying anomaly alarming device, is installed in a rack 10, rotates and set in the rack 10 It is equipped with a directive wheel 20, multiple positioning columns 21 are distributed along the circumference on the circumferential surface of the directive wheel 20, positioning column 21 can be plugged into In pocket on carrier band, to form the positioning to carrier band.The warning device include the baffle 30 being oppositely arranged and substrate 40, with And for making the baffle 30 to the close elastic component 70 of the circumferential surface of the directive wheel 20, the baffle 30 is close to the directive wheel 20 settings, the substrate 40 are arranged far from the directive wheel 20, and the side of the baffle 30 is provided with a guide groove 31, the other side is set Have a moving contact 50, the side of the baffle 30 towards the circumferential surface of the directive wheel 20, the width of the guide groove 31 with The width of the directive wheel 20 is adapted, i.e. the width of guide groove 31 is equal or slightly larger than the width of directive wheel 20, the guiding Positioning column 21 on the circumferential surface of directive wheel 20 described in 31 face of slot.Under natural conditions, the slot bottom of guide groove 31 is in elastic component 70 The lower holding of one or more positioning columns 21 on directive wheel 20 of effect abuts, if guide groove 31 is straight-line groove, only has one A positioning column 21 is abutted with the holding of the slot bottom of guide groove 31, at least can be there are two positioning column 21 if guide groove 31 is curved groove It is abutted with the holding of the slot bottom of guide groove 31, it is straight-line groove that slot 31 is preferably directed in the present embodiment.The elastic component 70 is spring, institute At least one end for stating spring is fixedly connected with the baffle 30 or the substrate 40.The substrate 40 is fixed at the rack On 10 and static contact 60 is which is provided with, the moving contact 50 and the static contact 60 are arranged in an alarm circuit, preferably baffle 30 and substrate 40 be made of insulating material, the preferably described alarm circuit includes buzzer 80.Under normal circumstances, carrier band is being oriented to Wheel 20 leads the guide groove 31 passed downwardly through on baffle 30, and moving contact 50 is not in contact with static contact 60 at this time, when carrier band starts When being detached from from directive wheel 20, being detached from part cannot pass through from guide groove 31, and can be by baffle 30 to far from directive wheel 20 Direction jacks up, and to which baffle 30 is moved to substrate 40, and then moving contact 50 is driven to be moved to static contact 60, and finally so that dynamic touch First 50 and static contact 60 contact, alarm circuit connect, the buzzer 80 being arranged on alarm circuit sends out alarm, to remind worker Carrier band conveying exists abnormal.

As being further improved for said program, one end of the baffle 30 is hinged with the rack 10, and setting in this way makes Overall structure more simply with it is compact.If baffle 30 is moved with being oppositely oriented wheel 20 with the state of 40 keeping parallelism of substrate always, It then needs that two guide posts are at least arranged, with for being oriented to the movement of baffle 30, this scheme can make overall structure Relative complex and occupied space.

As being further improved for said program, the static contact 60 be one pass through the substrate 40 and with the substrate 40 bolts being threadedly coupled are detached from directive wheel 20 convenient for adjusting the spacing between static contact 60 and moving contact 50 to ensure to carry When moving contact 50 can normally be contacted with static contact 60.

The advantages of basic principles and main features and the utility model of the utility model have been shown and described above, for For those skilled in the art, it is clear that the present invention is not limited to the details of the above exemplary embodiments, and without departing substantially from this In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the utility model is by institute Attached claim rather than above description limit, it is intended that will fall within the meaning and scope of the equivalent requirements of the claims All changes are embraced therein.

In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiment being appreciated that.
