The utility model patent of CN206397411U discloses a kind of electric rolling door of energy saving, and plane scroll is equipped in reel
Spring, the effect of plane scroll spring are to keep switch door curtain laborsaving.When putting down door curtain, the elongated change of the hanging portion of door curtain
Weight, spool turns drive plane scroll spring tightening, and elastic force increases, the gravity of door curtain hanging portion and plane scroll spring
Elastic force is in equilibrium state, its gravitional force is converted into the elastic potential energy of plane scroll spring during roller shutter decline；Open door
When curtain, door curtain rises, and hanging portion gravity reduces, and reel drives plane scroll spring to follow diastole, and elastic force reduces, door curtain
The elastic force of the gravity of hanging portion and plane scroll spring is still in equilibrium state, in door curtain uphill process, plane scroll spring
Elastic potential energy be converted into the gravitional force of roller shutter, as long as door curtain door roller during raising and lowering overcomes and door curtain guide rail
Between frictional force, therefore door roller being capable of energy saving.General rolling screen door will stay certain length in guide rail after opening
It is interior, that is, there is the roller shutter of certain length to keep hang, is not wrapped on reel all.In order to keep sagging length appropriate,
Reach optimal energy saving effect, just must apply certain torsion to plane scroll spring after the installation is completed in reel, make
The stress for obtaining roller shutter keeps balance.The existing method for applying torsion is to be grasped using more people with the method that hand has spool turns in arms
Make, since the installation site of reel is higher, this method is time-consuming and laborious.

Specific embodiment
As shown in Figs 1-4, the embodiments of the present invention, including supporting plate 1, guide rail 2, spool 3, reel 4, roller shutter 5, volume
Door machine 6, limiter 7 and torsional spring 8；The supporting plate 1 is divided into above door opening on the wall of two sides, and guide rail 2 is divided into door opening two
Side, 3 both ends of spool are fixedly connected with supporting plate 1, and 4 sets of reel are rotatablely connected outside spool 3 with it, and reel 4 is equipped with for pacifying
Fill the screw 9 of roller shutter 5；The roller shutter 5 is hinged by the curtain sheet 10 of multiple strips and is connected in series, and the upper end of the roller shutter 5 is logical
It crosses screw 9 to be mounted on reel 4, roller shutter 5 can be wrapped on reel 4 and can slide up and down along guide rail 2；The door roller 6 is set to
On the supporting plate 1 of 3 one end of spool, which is equipped with controller（It is not drawn into figure）；The limiter 7 is for controlling roller shutter 5
Raising and lowering is automatically stopped position, and the limiter 7 and the transmission connection of door roller 6 and controller are electrically connected；The torsional spring 8
It covers and is attached in reel 4 in spool 3；Adjustment wheel 11, anti-lever 12 and anti-dynamic pin 13 are equipped in the reel 4；The adjustment wheel
It 11 and the rotation connection of spool 3 and cannot slide axially on spool 3, excircle is equipped with several opening radial counterbores outwardly
14, for the torsion of uniformly adjustment torsional spring 8, the along the circumferential direction spaced set of counterbore 14；The anti-lever 12 is set to adjustment wheel 11
Radial outside, the anti-lever 12 are fixedly connected with spool 3；The anti-dynamic pin 13 and counterbore 14 match, which is inserted into
It is located at one end outside counterbore 14 and can lean against in anti-lever 12 after counterbore 14；It is set on the reel 4 of 11 corresponding positions of the adjustment wheel
There are 3 flutings 15, it is the torsion for adjusting torsional spring 8 for convenience that 3 flutings 15, which are arranged,；4 inner wall of one end and reel of the torsional spring 8
It is fixedly connected, the other end is fixedly connected with adjustment wheel 11；One end of the reel 4 is equipped with driven sprocket 16, the driven sprocket 16
Door roller 6 is connected by chain-drive mechanism 17；It further include adjustment bar 18, the adjustment bar 18 may pass through fluting 15 and inject counterbore 14
Interior, the diameter of diameter and counterbore 14 matches.
Working principle is：When the torsion of discovery torsional spring 8 and the weight mismatch of roller shutter 5, need to increase the torsion of torsional spring 8
When, it first closes roller shutter 5 and exposes fluting 15, bar 18 will be adjusted pass through fluting 15 and inject in the counterbore 14 of adjustment wheel 11 to tightening torsional spring
8 direction rotation adjustment wheel 11, since roller shutter 5 is hung on reel 4, reel 4 will not be rotated and then, and 11 rotation of adjustment wheel, which drives, to be turned round
Spring 8 rotates, its torsion just changes after torsional spring 8 rotates, and the anti-dynamic pin 13 leaned against in anti-lever 12 at this time can follow adjustment wheel
11 are rotated away from anti-lever 12, remove anti-dynamic pin 13, inject in the counterbore 14 nearest from anti-lever 12, back unclamp adjustment bar 18
Afterwards, adjustment wheel 11 can turn round under the action of 8 torsion of torsional spring, lean against anti-dynamic pin 13 again in anti-lever 12, then remove adjustment
Bar 18 converts counterbore 14 and continues to rotate adjustment wheel 11 to the direction for tightening torsional spring 8, then removes anti-dynamic pin 13, injects from anti-lever 12
In nearest counterbore 14, lean against anti-dynamic pin 13 again in anti-lever 12 after unclamping adjustment bar 18 further back, repeatedly
Torsional spring 8 is gradually tightened, to increase the torsion of torsional spring 8；When reducing the torsion of torsional spring 8, as long as adjustment is taken turns 11 toward phase negative side
To rotation.
It is laborsaving that the effect of torsional spring 8 is to enable to switch rolling screen door, functions as " the plane introduced in background technique
Scroll spring ", when door roller 6 puts down roller shutter 5 with the rotation of movable reel 4, the elongated change weight of the hanging portion of roller shutter 5, reel 4 is rotated
Torsional spring 8 is driven to tighten, elastic force increases, and the gravity of 5 hanging portion of roller shutter and the elastic force of torsional spring 8 are in equilibrium state, under roller shutter 5
Its gravitional force is converted into the elastic potential energy of torsional spring 8 during drop；When door roller 6 is with 4 rotating opening roller shutter 5 of movable reel, roller shutter 5
Rise, hanging portion gravity reduces, and reel 4 drives torsional spring 8 to follow diastole, and elastic force reduces, the gravity of 5 hanging portion of roller shutter
With the elastic force of torsional spring 8 still in equilibrium state, in 5 uphill process of roller shutter, the elastic potential energy of torsional spring 8 is converted into the gravity of roller shutter 5
Potential energy, as long as the door roller 6 during raising and lowering of roller shutter 5 overcomes the frictional force between roller shutter 5 and guide rail 2, switch
Roller shutter 5 is relatively labor-saving, being capable of energy saving.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
