Preferably, said secondary nip rolls group is made up of one group of high hardness friction roller, to reduce the damage of traction to tow, increases the friction roller life-span, reduces the winding of tow pair roller.Friction roller is by synchronous machine drives, in order to improve speed of response.
Preferably, said main nip rolls group is made up of another group high hardness friction roller, and with drawing the treatment tub group of tow between major and minor nip rolls group, main nip rolls group is also by synchronous machine drives.
Preferably, design and installation has said tension force inspection to survey the ∕ shock absorber between said secondary nip rolls group and main nip rolls group.
Preferably, the detection deflector roll of installing on the ∕ shock absorber is surveyed in said tension force inspection, when detecting tension force; Can be along with the variation crank motion of tension force size; With the variation of buffering tension force, reduce control system to performance demands such as signal resolution, speed of response, cost-cutting; And avoid or reduce the generation of concussion, make the tow smooth running.The detection of tension force and buffering also can be realized by two devices respectively.
Preferably, said wind-up roll is rotated by motor-driven, tow is drawn from main nip rolls group, and tow is carried out rolling.
Preferably, design and installation has said tension force detection/shock absorber between said main nip rolls group and wind-up roll, is used to detect the tension force size cases of the tow between main nip rolls group and the wind-up roll, and tow tension has been changed buffer action.
Preferably, tenslator is installed in the appropriate location, and the signal that tension force detection/shock absorber is sent carries out computing, sends to the drive motor of secondary nip rolls group and wind-up roll, causes the drive motor velocity variations, to change tension force.
Description of drawings
Accompanying drawing 1 is the scheme drawing according to the structure of a preferred embodiment of traction that is used for the tow arrangement of the utility model and tenslator.
Description of drawings: let off roll 1, secondary nip rolls group 3, tension force Jian Ce ∕ shock absorber 4, main nip rolls group 5, wind-up roll 6.
The specific embodiment
Below in conjunction with accompanying drawing the content of the utility model is described, following description only is exemplary and indicative, and the protection domain to the utility model does not have any restriction.
As illustrating structure according to the preferred embodiment of the traction that is used for tow arrangement of the utility model and tenslator, it comprises let off roll 1, secondary nip rolls group 3, tension force Jian Ce ∕ shock absorber 4, main nip rolls group 5, wind-up roll 6, tenslator.
As shown in Figure 1, in the design and installation of the one or both ends of let off roll 1 damping is arranged, through straightforward procedure such as spring or weight let off roll 1 is applied damping, can realize having tension force when tow unreels, lower cost is arranged again.3 design and installations of secondary nip rolls group are after let off roll 1, and the tow on the traction let off roll 1 tentatively imposes tractive force to the tow on the let off roll 1, and tow is drawn from let off roll 1 uniformly.Secondary nip rolls group 3 is made up of one group of friction roller, by synchronous machine drives.Main nip rolls group 5 is designed to one group of friction roller, and with drawing the treatment tub group of tow between major and minor nip rolls group, main nip rolls group 5 is by synchronous machine drives.The detection deflector roll of installing on the tension force detection/shock absorber 4; When it detects tension force, can be along with the variation crank motion of tension force size, with the variation of buffering tension force; Reduce control system to performance demands such as signal resolution, speed of response; Cost-cutting, and avoid or reduce the generation of concussion, make the tow smooth running.Design and installation has tension force Jian Ce ∕ shock absorber 4 between secondary nip rolls group 3 and main nip rolls group 5, is used to detect the tension force size cases of the tow between secondary nip rolls group 3 and the main nip rolls group 5, and tow is played buffer action.Wind-up roll 6 is drawn tow, and tow is carried out rolling by the drive motor drives rotation from main nip rolls group 5.Design and installation has tension force detection/shock absorber 4 between main nip rolls group 5 and wind-up roll 6, is used to detect the tension force size cases of the tow between main nip rolls group 5 and the wind-up roll 6, and tow is played buffer action.Tenslator is installed in the appropriate location; The signal that tension force detection/shock absorber 4 is sent carries out computing, sends to the drive motor of secondary nip rolls group 3 and wind-up roll 6, causes the drive motor velocity variations; To change tension force; When detecting tension force greater than setting tension force, send signal secondary nip rolls group 3 is quickened or wind-up roll 6 decelerations, tension force reduces thereupon; Vice versa.
