Electric coiling spacing detection device

Abstract

The invention discloses an electric winding limit detecting device with correct positioning and safety and reliability. The electric winding limit detecting device comprises a core tube. The core tube is provided with an opening; a core tube plug and a core tube rotator are arranged inside the two ends of the core tube respectively; one end of the core tube is movably arranged in a left end cover through the core tube plug; and the other end of the core tube is connected with an output shaft of a synchronous machine arranged in a vibration reduction motor cabinet through the core tube rotator. A switch mounting seat is also fixed on the vibration reduction motor cabinet on the lower end of the core tube rotator; and an upper limit detecting switch and a lower limit detecting switch are respectively arranged inside the switch mounting seat. The electric winding limit detecting device has the advantages that the device overcomes the defect of incorrect positioning of the upper and lower limit detecting switches due to easy displacement, thereby ensuring the correct position of the upper and lower limits for a winding object; and simultaneously the safety performance of the whole limit detecting device is reliably guaranteed and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to a limit detection device for detecting the position of winding objects in an electric shutter. Background technique [0002] As we all know, electric roller blinds used for winding screens, curtains and other winding objects are equipped with a controller and a limit detection device. The structure of the limit detection device usually includes: a screw fixedly connected to the output shaft of the motor, The screw rod is provided with a travel nut through the thread, and the upper and lower limit detection switches are respectively arranged on both sides of the screw rod, and the positions of the upper and lower limit detection switches can be adjusted. The controller that runs the motor is connected. During production debugging, adjust the relative positions of the upper and lower limit detection switches and the stroke nut, so that the stroke between them and the stroke nut corresponds to the upper and lower strokes of windi...

AI Technical Summary

Problems solved by technology

The disadvantage of this limit detection device is: the position of the upper and lower limit detection switches is easy to move due to the vibration in the process of transportation and handling, so that it is different from the actual upper and lower limit positions of winding objects such as screens or curtains. Corresponding, resulting in inaccurate positioning; serious damage to the electric roller shutter
