Beneficial effects of the present invention：When needing curtain to transfer in use, ropewinder discharges traction rope, and pipe crimping is in gravity
Lower rotation is fallen, and traction rope is rolled up on pipe crimping, meanwhile, the curtain rolled up on pipe crimping is gradually spread out；When needing to pack up on curtain,
Ropewinder tightens traction rope, drives convolution to turn while traction rope is taken off from pipe crimping, under the action of the rotating force, curtain
The gradual volume of cloth finally realizes that curtain winding, the present invention are abandoned in the prior art using spool on pipe crimping while being promoted
Technical solution, structure novel, and disclosure satisfy that large-scale or ultra-large type projection screen requirement.
The weight of common overwind screen of dynamoelectric projection, pipe crimping and curtain is to influence the unfavorable factor of curtain face planarization：Volume
The weight of pipe and curtain is applied on pipe crimping, is made pipe crimping that the sagging flexure in middle part due to gravity be presented, is led to an act face out-of-flatness, even
When pipe crimping bending is excessive, winding curtain will produce an act face fold, and irreversible damage is caused to curtain.
And the weight of the underwind screen of dynamoelectric projection of this programme, pipe crimping and curtain is changed into the favorable factor in act face.Pipe crimping
It is disposed on the lower end in act face, curtain face can be tightened because of the weight of pipe crimping, and the dead weight in curtain face itself is also advantageous that in the flat of curtain face
On whole, therefore the effect of the two is all to keep act face more smooth.Meanwhile the weight of pipe crimping and the curtain face being wrapped on pipe crimping, meeting
Power is tightened to traction rope application, so that traction rope is tightly wrapped ropewinder, to make transmission system stable working state.
