Description

Single motor drive formula roller shutter

Technical Field

The utility model belongs to sunshade facility field, concretely relates to sunshade facility that is used for glass top surfaces such as sunshine room, daylighting top to install.

Background

The existing horizontally-running aluminum alloy foaming roller shutter mainly adopts two technical forms of 'double-motor driving + steel wire rope or steel belt traction' and 'single-motor driving + torsion spring + steel belt traction'.

The former technology of 'double motors + steel wire ropes or steel belts' is a technology of synchronously driving the curtain sheet and drawing the steel wire ropes or steel belts to wind through the simultaneous operation of two synchronous motors so as to realize the horizontal operation of the curtain sheet. The technology has the problems of high cost (two motors), large volume (two sets of motor winding devices require the volume of a cover shell to be wrapped and placed to be correspondingly increased, and the size of the cover shell is at least 300 x 300mm), and the like. In addition, the motor is subjected to a large load in a rigid traction mode of a steel wire rope or a steel belt, and the failure rate of the motor is high.

The latter technology of single motor + torsional spring + steel band is that the single motor drives the curtain sheet to be rolled up, and the reverse rotation force application torsional spring drives the flat band to tighten up the curtain sheet, so as to realize the horizontal operation of the curtain sheet. The technology also has the problems of high cost (torsion springs with different thicknesses and lengths are required to be customized in different strokes) and large volume (the volume of a cover shell which is wrapped and placed by two sets of winding devices of the motor and the torsion spring is required to be correspondingly increased, and the size of the cover shell is at least 300 x 300 mm). In addition, as the flat belt and the curtain sheet are wrapped, the flat belt and the two hard metals of the curtain sheet rub with each other during operation, and the long-term operation can cause the abrasion of the paint layer on the surface of the curtain sheet until the curtain sheet is worn, thereby influencing the service life of the roller shutter.

Meanwhile, when the single width area is relatively large (the width or the stroke is increased), the long-time up-and-down rolling operation can cause the curtain sheet to slightly deviate leftwards or rightwards, and because the two sides of the curtain sheet only have the movement clearance of less than 10mm, the slight movement can cause the curtain sheet to scratch the structure, so the curtain sheet is damaged if the curtain sheet is light, the structure is damaged if the curtain sheet is heavy, and the maintenance rate is high.
