Abstract
The utility model discloses a screen tensioning device. The screen tensioning device comprises tensioning wheels and a hanging rod, wherein a screen is hung on the hanging rod, tensioning steel wire ropes on each tensioning wheel extend upwards on the two sides of the screen and are fixed to the corresponding end of the hanging rod, tensioning springs are connected between the two sides of the screen and the tensioning steel wire rope on the corresponding side respectively, and a plurality of tensioning springs are also connected between the positions on the ground at the bottom of the screen. According to the screen tensioning device, climbing operation is not needed when the screen is tensioned, man power is saved, the screen tensioning device is safe for use, the regulating effect is played at the right moment when the screen deforms in the spraying process of the screen due to the surrounding springs, the screen can be made in the smooth state all the time, and the uniformity of the produced screen is improved.
Description
Technical field
The utility model relates to tension device field, is specially a kind of screen tension device.
Background technique
Movie screen size is larger, and most screen width surpasses 10 meters, highly over 6 meters, and the surface treatment of screen generally all adopts the mode of spraying, make the uniformity of screen surface spraying reach requirement, when spraying, must, by screen tensioning, reach view picture screen all very smooth.
Traditional method is in screen, to hang up position a motorized winch batten is set, the both sides of screen respectively arrange a vertical stand that has some strength, after screen is fixed on suspension rod and is risen, staff climbs in vertical stand and with rope, screen is tightened up to both sides, working strength is larger, owing to being high-lift operation, so there is certain operating risk.
Screen, in the process of spraying, is subject to the impact of solvent, and it is large that the screen meeting of tensioning becomes, and causes tension force inadequate, and screen meeting generation fold, causes spraying effect bad, affects quality of product, even unqualified.
Model utility content
The purpose of this utility model is to provide a kind of screen tension device, the problem existing to solve prior art.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of screen tension device, it is characterized in that: include a pair of fix on the ground tighten up wheel, and suspend and the two liftable suspension rods that tighten up above taking turns, on described suspension rod, be hung with the screen naturally drooping above tightening up between wheel to two, each tightens up and on wheel, is wound with respectively tensioning wire rope, described tensioning wire rope in screen both sides, extends upward respectively and end is separately fixed at suspension rod corresponding end, between the tensioning wire rope of described screen both sides and respective side, be connected with respectively multiple tracks tension spring, described screen bottom and two is tightened up between wheel ground, place and is also connected with multiple tracks tension spring.
Described a kind of screen tension device, is characterized in that: hang on suspension rod by many groups screen hook at described screen top.
Described a kind of screen tension device, is characterized in that: described suspension rod top is also connected with multiple tracks hoisting wirerope.
The utility model tensioning screen does not need ascend operation, save artificial and safety, spring by surrounding plays corrective action while causing screen distortion in the spraying process of screen in good time, makes screen all the time in formation state, has improved the uniformity of institute's production screen.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1.A kind of screen tension device, include a pair of tightening up of fixing on the ground and take turns 1, and suspend with two tighten up wheel 1 top liftable suspension rod 2, on suspension rod 2, be hung with the screen 3 naturally drooping above tightening up between wheel 1 to two, each tightens up on wheel 1 and is wound with respectively tensioning wire rope 4, tensioning wire rope 4 in screen 3 both sides, extends upward respectively and end is separately fixed at suspension rod 2 corresponding end, between screen 3 both sides and the tensioning wire rope 4 of respective side, be connected with respectively multiple tracks tension spring 5, screen 3 bottoms and two are tightened up between wheel 1 ground, place and are also connected with multiple tracks tension spring 6.Hang on suspension rod 2 by many groups screen hook 7 at screen 3 tops.Suspension rod 2 tops are also connected with multiple tracks hoisting wirerope 8.
