Description
Technical field
The utility model relates to radial tyre steel cord production equipment, refers to a kind of steel curtain line tension equalising control device particularly.
Background technology
At present; In the radial tyre steel cord production equipment both domestic and external; Steel curtain line tension equalising control device structure and principle are following: the frictional disk outside at steel cord rotating assembly centers on the open loop chain that the band friction block is set; One end of open loop chain links to each other with frame, and the other end connects extension spring, and the other end of extension spring links to each other with frame through regulating bolt.Elongation through regulating extension spring is adjusted the pressure between frictional disk and the friction block, and then the adjustment moment of friction is to reach the purpose of balanced steel curtain line tension.Because the rigidity of extension spring is certain; Factors such as the little and frictional heating of friction block contact area cause the fluctuation of steel curtain line tension big, and this device can not realize that steel curtain line tension real-time adaptive regulates; The balancing tension effect is relatively poor, can't guarantee the quality of production of steel cord.
Summary of the invention
The purpose of the utility model will provide a kind of steel curtain line tension equalising control device exactly, realizes the adjusting of steel curtain line tension real-time adaptive, improves the quality of production of steel cord.
For realizing above-mentioned purpose, the steel curtain line tension equalising control device that the utility model designed comprises frame, is arranged on the steel cord rotating assembly on the frame and fixed the line column.Also being provided with on the said frame can be around the tension lever of lever shaft rotation, and an end of said tension lever is provided with the movable line column of crossing, and the other end links to each other with an end of extension spring, and the other end of said extension spring links to each other with frame.The base circumference side of said steel cord rotating assembly is provided with frictional disk, and the outside of said frictional disk is around being provided with the open loop chain.One end of said open loop chain is fixed on the frame, and the other end of said open loop chain is fixed on the tension lever, and its fixing point is lever shaft and movable the mistake between the line column.The chain of said open loop chain is provided with the some friction blocks that match with frictional disk circumference side on one's body.
Further, regulate the elastic force of extension spring for ease, the other end of said extension spring is regulated bolt through first and is linked to each other with frame.One end of said open loop chain is regulated bolt through second and is linked to each other with frame, is used to adjust the pressure between frictional disk and the friction block.
As preferably, the quantity of said friction block is 3～5.
The advantage of the utility model is: the steel curtain line tension equalising control device that is designed can be realized the adjusting of steel curtain line tension real-time adaptive through the extension spring that is arranged on the tension lever on the frame and is attached thereto.When fluctuation took place steel wire tension, extension spring, tension lever and open loop chain can be adjusted thereupon accordingly, the tension force of balance steel cord again, and it is constant that tension force is kept in ± 10% scope.After the friction block wearing and tearing, can make tension force maintain original state through regulating the extension spring elongation.After friction block lost efficacy, an end that unclamps the open loop chain can be pulled down friction block and change, and was simple to operate.
