摘要： The present invention provides a constant force multiple spring curtain winding system, including a mounting bracket fixedly connected to a wall, and a revolving drum connected to a curtain, wherein one end of the mounting bracket is connected to a rotating rod through a speed change mechanism, a constant force spring mechanism fixedly connected to the revolving drum is arranged on the rotating rod, and the rotating rod is fixedly connected to a constant force elastic piece in the constant force spring mechanism. According to the present invention, a speed of the revolving drum is adjusted by the speed change mechanism, and the rotating rod rotates at a low speed by the speed change mechanism when the revolving drum rotates at a high speed, thus ensuring that the revolving drum rotates for enough turns to meet a height of the curtain, maximizing a width of the curtain and reducing a counterweight of a lower rail of the curtain; and the requirement on the size of the curtain is met by increasing or decreasing the number of the constant force spring mechanisms, and the curtain is capable of staying at any positions. The constant force multiple spring curtain winding system is novel in structure, simple to operate, wide in application and easy to popularize.

摘要： Disclosed is a customized blinds&shades cutting apparatus. The customized blinds&shades cutting apparatus comprises a working platform. The working platform is provided with a blinds&shades fabric cutting mechanism, a blinds&shades integrated cutting mechanism and an adjustable positioning mechanism. The blinds&shades fabric cutting mechanism comprises a first base, a first motor is fixedly mounted on the first base, a connected shaft is mounted on a rotating shaft of the first motor, and a cutter knife is further movably arranged on the first base; the blinds&shades integrated cutting mechanism comprises a second base, an aligning and cutting die is arranged on the second base, a cutting groove is formed on the working platform, the second base and the aligning and cutting die, and the blinds&shades integrated cutting mechanism further comprises saw webs corresponding to the cutting grooves in position. The customized blinds&shades cutting apparatus is novel in structure and ingenious in design. The customized blinds&shades cutting apparatus with a novel structure and an ingenious conception enables to manufacture clamps, housings, lower beams and lower round pipes of blinds&shadess with different sizes and models by using the blinds&shades fabric cutting mechanism, the blinds&shades integrated cutting mechanism and the adjustable positioning mechanism to clamp and cut four profiles: a reel pipe, an upper housing, a lower beam and a lower round pipe, so that the processing efficiency is high.
