Description
Technical field
The utility model is related to non-woven cloths to fabricate field, more particularly to a kind of to be used for non-woven fabrics tension bracket.
Background technology
In the production process of non-woven fabrics, the tension of non-woven fabrics, tension bracket energy side are adjusted frequently by tension bracket is used
Just tension is fast adjusted.
Currently, the Chinese patent of 206308494 U of Publication No. CN discloses a kind of tension bracket for laminating machine, it
It is rotated including two symmetrically arranged holders, on the holder and is provided with driving member, be located between the driving member on two side stands
Rotation is provided with the first regulating roller and the second regulating roller, and first for adjusting driving member angle is provided on the holder and is adjusted
Structure is provided with regulation ring around first regulating roller, is provided on driving member for adjusting regulation ring and the first regulating roller
Between push against amount of force the second adjustment structure.When being tensioned non-woven fabrics by tension bracket, non-woven fabrics bypasses the respectively
One regulating roller and the second regulating roller, and the first regulating roller and the second regulating roller is driven to turn during being moved with non-woven fabrics
It is dynamic, non-woven fabrics is understood also by the drag effect of the first regulating roller and the second regulating roller by the interaction of power at this time, and
The non-woven fabrics made under the action of this resistance keeps smooth, when the drag size of the first regulating roller and the second regulating roller is inadequate,
By rotating the second adjustment structure, and increase the drag size between regulation ring and the first regulating roller, while slowing down the first adjusting
The rotating speed of roller, to increase the action time between non-woven fabrics and the first regulating roller, the cloth non-woven fabrics mistake of such equal length
Will be acted on by bigger when holder, so can Zhang get Geng it is tight；But if even if the first regulating roller stops operating, the
Drag size that one regulating roller and the second regulating roller apply or it is inadequate when, rotate the first adjustment structure, and drive driving member turn
Dynamic, such non-woven fabrics just changes around the angle of the first regulating roller and the second regulating roller, at the same also increase non-woven fabrics with
Gross contact area between first regulating roller and the second regulating roller, when such non-woven fabrics is by the first regulating roller and the second regulating roller
Further cloth cover can be tensioned, so that tension effects reach ideal, the then change of lap meeting in nonwoven production
There is tension reduction suddenly or non-woven fabrics both ends tension is different, this tension bracket cannot be solved effectively.
Utility model content
The purpose of this utility model is to provide a kind of automatically adjusting cloth cover by Tensity size by adjusting counterweight box weight；
It adjusts and leading screw in live-roller holder device is adjusted and then cloth cover both ends Tensity size is adjusted, to reach face tension
Stable and consistent is used for non-woven fabrics tension bracket.
The utility model includes mainly chain drive guide roller, live-roller, slideway, adjustable live-roller holder device, silk
Thick stick, counterweight box, adjustable live-roller, location nut, gear, chain, clump weight, sliding block, holder, square steel, reinforcing rib, limit
Block, bearing and bearing block.
Wherein, the upper and lower part between two symmetrical holders is respectively equipped with two groups of vertical square steel, every group of square steel
In same level.It is fixedly connected with reinforcing rib at the both ends of holder, is used to support tension bracket.It is set respectively on symmetrical holder
There is vertical slideway, limited block is fixed respectively in the top and bottom of every slideway.On holder by nut fix two it is right
The live-roller of title is equipped with bearing in live-roller.One group of bearing block is fixed on every reinforcing rib, is set between every group of bearing block
There is chain drive guide roller, distinguishes grafting gear at the both ends of every chain drive guide roller.It is led in upper and lower two chain drives
It is connected between the corresponding gear of roller by chain.Counterweight box is equipped between the both ends of chain, counterweight box is a side opening
Square casing, clump weight is placed in counterweight box.Transmission is adjusted in the fixedly adjustable section live-roller holder device on chain
Roller support device includes leading screw, location nut, adjustable live-roller, and the both ends that live-roller is adjusted are equipped with sliding block, sliding block
Be slidably connected in corresponding slideway, each sliding block is connected with leading screw respectively, location nut fix slide position, cloth cover both ends by
When power is uneven, Adjustable tension bracket one end location nut position makes adjustable live-roller one end be lifted.
When the utility model is used, it is of different sizes to bear external force according to non-woven fabrics difference grammes per square metre, suitably increase and decrease counterweight box
Weight makes adjustable live-roller in slideway centre position, and when the unexpected stress of non-woven fabrics changes, adjustable live-roller is by prolonging
Slideway slides up and down to reduce tension variation, and cloth cover is avoided to be broken or excessively relax, and winding cloth cover is caused the problems such as fold occur.
Cloth cover both ends discontinuity, tension suitable one end tension in one end is small or big, and the small or big one end of tension can be by adjusting fixed
Position nut, which changes, adjusts the live-roller end floating position, the small downward adjusting of tension, otherwise is adjusted up, it is ensured that cloth cover is whole
Tension-proof is consistent.
The utility model has the following advantages that compared with prior art：
1, when unexpected tension variation occurs in cloth cover, adjusting live-roller prolongs slideway direction and floats up and down, reduces and open suddenly automatically
Power changes the influence to cloth cover.
2, external force difference can be born according to cloth grammes per square metre difference, can suitably increases and decreases the weight of counterweight box, cloth grammes per square metre is bigger, matches
Weight box weight is smaller.
3, there is both ends tension difference in cloth cover two, can be by adjusting adjustable live-roller one end height, to make cloth cover
Tension-proof is consistent.
