Do you have this problem when designing cordless blinds?

Quelle:Qianye-Präzision Zeit:2023-3-6

When the curtain is pulled to the top it sags and when it is pulled to the bottom it springs back a certain height.

 

Qianye Spring Company has succeeded in developing this cordless blinds spring. The steps in the design of a cordless curtain spring are as follows.

  1. 1. Determining the size of the winding spring force

It is usually necessary to determine the weight of the curtain. It is usually possible to measure the force required to hold the cordless curtain at the top and to measure the force required to hold the cordless curtain at the bottom.

 

  1. Determining the spring life

It is usually necessary to determine the duration of use of the curtain. For example, a spring with a life of 8,000 strokes will not loosen or deform within the life of the spring.

 

  1. Determining the space in which the spring is to be installed

The space where the spring is to be placed, the distance between the two springs, the outer diameter of the spring, etc. should be taken into account.

 

  1. 4. Adjustment of the curtain spring after trial

This stage is usually the adjustment of the force. For example, increasing the force of the spring at the beginning or decreasing the force of the spring at the end.
