As shown in fig. 1 to 3, the enclosed-housing magnetic contact type rotary dial counting device provided by the invention comprises a fixedmounting shaft 1, an enclosedhousing 2, adial 3 and adetection piece 4. Wherein,seal shell 2 cover is established onfixed mounting axle 1 and can rotate around fixed mountingaxle 1, and wherein, fixed mounting axle 11 passes through the bearing to be fixed in one side of outside transmission device,dials 3 and the axial looks perpendicular of fixedmounting axle 1, anddials 3 and be located transmission device's top, and the incoming material direction of waiting the count object that transmits on the transmission device is unanimous, so, is located the waiting of transmission device top and counts the object and just can promote anddial 3 rotation. . Thedial 3 is arranged on the outer side wall of the closedshell 2, and thedetection piece 4 is of a protruding structure, is arranged on the inner side wall of the closed shell and corresponds to thedial 3.
It should be noted that, the correspondence here refers to how many dialing codes are provided on the outer side wall of the closedcasing 2, and how many raised detection pieces are provided on the inner side wall of the closed casing correspondingly. In one example of the present invention, the closedhousing 2 is a hollow cylindrical structure, and the outer side wall of the cylindrical structure is uniformly provided with 3 dialing codes of a plate shape or a cylindrical structure, and then, correspondingly, the inner side wall of the hollow cylindrical structure is also provided with 3 raised detection pieces, wherein each detection piece corresponds to one dialing code.
In addition, a magnetic electric contact piece 5 is fixedly arranged on the fixedmounting shaft 1, an object to be counted touches thedialing code 3 in the transmission process (namely, the dialing code is touched by the object to be counted in the transmission process), thedialing code 3 drives the closedshell 2 to rotate, so that adetection piece 4 arranged in the closedshell 2 rotates along with the closedshell 2, when thedetection piece 4 approaches the magnetic electric contact piece 5 in the rotation process, electromagnetic induction is necessarily generated between thedetection piece 4 and the magnetic electric contact piece 5, a detection signal for the object to be counted to pass through is generated through the electromagnetic induction generated between the magnetic electric contact piece 5 and thedetection piece 4, and the object to be counted can be counted according to the detection signal.
In particular, an external closed circuit is provided, to which the magnetic electrical contact strip is connected, by means of which a detection signal is generated for the passage of the object to be counted. The primary connection and disconnection of the closed loop is regarded as a detection signal for passing through an object to be counted generated by electromagnetic induction generated by the magnetic electric contact sheet and the detection sheet. Specifically, when the detection piece rotates to a position corresponding to the magnetic electric contact piece, the magnetic electric contact piece generates an electric signal for conducting the closed loop; when the detecting piece rotates to a position staggered with the magnetic electric contact piece, the magnetic electric contact piece generates an electric signal for opening the closed loop.

In addition, since the object to be counted touches the dialing code during the transmission process, namely: the object to be counted contacts with the dialing code, and the transmission speed of the transmission device is generally higher, so that the object to be counted is damaged to some extent due to the impact of inertia when contacting with the dialing code. Therefore, in the closed shell type magnetic contact type rotary dial counting device provided by the invention, the dial can be made of a few low-hardness high-wear-resistance materials, for example, the dial can be made of cast iron, babbitt alloy or bronze alloy and other materials, so that the object is prevented from being damaged when the object is contacted with the dial. Namely: the dialing code can be cast iron dialing code, babbitt alloy dialing code or bronze alloy dialing code.

The counting device provided by the invention is arranged in a gap below the conveying device, and the fixed installation shaft of the counting device is vertical to the incoming material direction of the objects to be counted conveyed by the conveying device, so that the dial can be triggered and rotated by angle steel in the conveying process. When the dial is rotated, the closed shell is driven to rotate, and as the protruding detection sheet structures are distributed on the inner side wall of the shell, the change of the magnetic electric contact sheet detection signal can be caused by the detection sheet, and the change of the signal is the detection signal with angle steel passing through.
In addition, the closed shell type magnetic contact type rotary dial counting device provided by the invention adopts a rotary structure, so that after the last dial is touched, the shell rotates, and the next dial can be pushed to the position where the angle steel passes, so that the next angle steel can be waited for passing. Through the rotary cyclic work of dial like this, send the signal that has the angle steel to pass through to the controller to just realized the cycle count of the angle steel transported on the conveyer.
According to the closed shell type magnetic contact type rotary dial counting device, the approach signal detection of the edge of the object is changed into the signal detection of the dial connecting component, so that the obtained object arrival signal is separated from the signal conversion transmission, the reliability of detection is improved, and the device is particularly suitable for counting objects with extremely small edge areas.
