Abstract
The utility model discloses a pneumatic web curtain constant tension control device, wherein a tension roll is driven by a cylinder to tension into a web curtain of a web forming machine to control the tension of the web curtain in a certain range and to maintain constant. The device enables two sides of the web curtain to be evenly tensioned through adjusting the pressure of the cylinders on twoends of the tension roll. Simultaneously, the stretching of the web curtain due to long-term work can be automatically eliminated. The device guarantees that the web curtain can stably work in certaintension range.
Description
Technical field
The utility model belongs to field of textile machinery, is particularly suitable for spun-bonded non-woven production line and the spunbond composite non-weaving cloth production line lapper equipment that melts and sprays.
Background technology
At present, product line of spinning viscose and the spunbond lapper lace curtaining that melts and sprays composite production line have only the lace curtaining tensioning apparatus, but do not have the tenslator of lace curtaining.
The lapper that has only the lace curtaining tensioning apparatus, along with the lace curtaining working time increases, lace curtaining can produce certain elongation, thereby the tension force of lace curtaining is reduced.If lace curtaining is too lax, fiber be will influence and net and conveying become, also can have influence on the work of lace curtaining deviation correcting device.For effectively overcoming the relaxation problem of lapper lace curtaining, guarantee that lace curtaining can keep metastable tension force in the course of the work, become the basis of technical solutions of the utility model.
The utility model content
The problem that product line of spinning viscose and the spunbond lace curtaining that melts and sprays the composite production line lapper can relax in the course of the work, disposable tensioning lace curtaining can not guarantee that lace curtaining works steadily in the long term.The utility model technology provides a kind of mode of dynamic tension lace curtaining, can effectively overcome the relaxation problem of lapper lace curtaining, guarantee that lace curtaining can keep metastable tension force in the course of the work, lace curtaining is tensioned in lax process in time, thereby guarantees its effective work.
The technical scheme that the pneumatic lace curtaining constant tension control device of the utility model is adopted is:
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a structure principle chart of the present utility model.
Each sequence number is expressed as follows among the figure: 1. lace curtaining, 2. backing roll, 3. jockey pulley, 4. cylinder, 5. backing roll.
The specific embodiment
Each roller is pressed diagramatic way and is arranged that lace curtaining is walked around each roller and formed pneumatic lace curtaining constant tension control device.Adjust the pressure regulator valve of jockey pulley two ends cylinder pressure respectively, make lace curtaining tensioning under certain force of strain, and guarantee lace curtaining both sides tensioning unanimity.Weight and the required tension force of lace curtaining according to jockey pulley calculate required air pressure, adjust the numerical value of pressure-reducing valve.
Claims (3)
1, a kind of pneumatic lace curtaining constant tension control device is characterized in that: backing roll (2), jockey pulley (3), backing roll (5), and to walk around each roller successively by lace curtaining (1) and form, cylinder (4) is arranged at jockey pulley (3) below.
2, pneumatic lace curtaining constant tension control device according to claim 1, it is characterized in that: cylinder (4) is controlled by two independent gas circuits.
3, pneumatic lace curtaining constant tension control device according to claim 1 is characterized in that: jockey pulley (3) is driven by cylinder (4), and the cylinder pressure of roller both sides is independent adjustable.
