The existing sensor switch is characterized in that a detected metal sheet is a circular iron sheet 7 (shown in figure 1) fixed on a support lug of a filter plate, and along with the appearance of adverse factors such as abrasion between the support lug of the filter plate and a rail, accumulation of assembly gaps of the support lug, flexible deformation of a support lug rail with the length of more than ten meters, errors of support lug processing precision and the like, hundreds of detected metal sheets which are ideally at the same height start to be uneven, and the height difference reaches more than 5 mm. The induction distance of the proximity sensor switch is 0-4mm, the highest detected metal sheet is taken as a reference, and a safe distance of 2mm is reserved between the sensor and the metal sheet, so that the height difference between the detected metal sheets on the hundreds of filter plates is required to be within 2mm, and the purpose cannot be realized by adjusting the height of the filter plates. Based on this, the utility model provides a from revising proximity sensor switch, under the condition that does not change the filter plate height difference, lean on the height that the regulation was detected the sheetmetal, realize the normal work of sensor, and the stroke of every turn is from revising, need not artificial intervention, reaches the purpose that 100% detected the discernment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a self-correcting proximity sensor switch solves the above-mentioned problem.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model relates to a self-correcting proximity sensor switch, which comprises a plate frame supporting beam and a washing device capable of walking on the plate frame supporting beam, wherein the washing device is provided with a sensor and an adjusting device in an inclined manner, and a flexible detected metal sheet is arranged in the adjusting device; the flexibility is detected the sheetmetal including being located inside the adjusting device the sheetmetal, and with sheetmetal fixed connection's ring, ring fixed connection is at the filter plate journal stirrup, the lower terminal surface slidable of filter plate journal stirrup sets up on the plate frame supporting beam.
Further, the cross-sectional shape of adjusting device is the C type.
