Description
The utility model relates to a kind of tension force Synchronization Control printing and dyeing joint machine, and described printing and dyeing joint machine is a kind of dyeing machine that has three padding machines at least.
In the tension force Synchronization Control of the printing and dyeing joint machine of three above padding machines, in order to control the fabric synchronous operation between each unit, so that fabric can not produce loose or phenomenon of rupture, promptly do not influence the crudy of fabric, the tension force Synchronization Control that present printing and dyeing joint machine adopts is confined to control the roll linear velocity by displacement detecting, so that the roll of each unit reaches synchronously, but there is not tension measuring device.When change in displacement, the tension force of fabric promptly produces fluctuation.For example: a kind of printing and dyeing joint machine that adopts lift speed to regulate, it mainly is made up of fabric guide roll, falling-rising roller, counterweight, sprocket wheel, chain, sensor etc., when fabric tension changes, just drive the motion together up and down of dance roller and chain, make the sprocket wheel revolution, signal is passed to displacement transducer, change the output signal of displacement transducer, regulate the rotating speed that rotating speed of motor changes roll by driver, make the linear velocity of front and back, same unit roll identical.Another kind is a tension force swing type linear velocity adjusting device, it mainly is made up of swing guide roller, lever, counterweight, sprocket wheel, chain, displacement transducer etc., after front and back roll linear velocity has elementary errors, fabric tension changes, and makes lever swing, by sprocket wheel, chain signal is passed to sensor, signal of sensor is changed, regulate rotating speed of motor by driver, thereby changed the rotating speed of a certain roll, the linear velocity of roll is identical before and after reaching.Above-mentioned two kinds of printing and dyeing joint machine are all by the linear differential of two roll shop buildings before and after the sky system of displacement is measured, and roll reaches synchronous operation before and after making, and is not the tension force of directly measuring fabric.These two kinds of structures all are to adopt the position that changes counterweight to realize to the setting of fabric tension, operation is inconvenience very, and the online tension force that is difficult for directly setting and controlling fabric, its purpose only keeps synchronously for roll before and after guaranteeing, and the required tension force difference of different fabrics, or environmental factor changes, and the required tension force of same fabric also changes, more than the tension force size can't accurately be set and control to device all, and repeatability is poor.
The purpose of this utility model provides a kind of simple in structure, can make each unit before and after roll keep synchronously, can directly measure again, online direct setting and control the tension force Synchronization Control printing and dyeing joint machine of fabric tension between each unit.
The utility model is that the technical scheme that achieves the above object is: a kind of tension force Synchronization Control printing and dyeing joint machine, have body, be packed at least one pair of the front and back roll on the body, the Drive and Control Circuit that is arranged at least one fabric guide roll between the roll of front and back and controls front and back roll action respectively, wherein, the axle head of at least one fabric guide roll is fixed with tension detecting apparatus, and one of Drive and Control Circuit of the output of tension detecting apparatus and front and back roll is joined.
Owing to be fixed with tension detecting apparatus connecting on the fabric guide roll of fabric, displacement detector in the tension force Synchronization Control before having replaced, when fabric passed the fabric guide roll operation, fabric formed certain cornerite on fabric guide roll, and the fabric tension of formation is measured through tension detecting apparatus and shown.When two breaker rolls produce the linear velocity elementary errors, the fabric tension that changes is sent into tension detecting apparatus, tension detecting apparatus is measured tension force on the one hand, control simultaneously the Drive and Control Circuit of a roll again, roll keeps synchronous operation before and after making, thereby has reached the purpose that roll before and after each unit keeps can directly measuring synchronously, again fabric tension.Simultaneously, require different fabrics for tension force, or when environmental change, when fabric tension need be changed, not deciding signal and can control tension force in the change tension detecting apparatus carried out online adjusting, setting to tension force, and repeatability is good.The utility model is owing to substituted the displacement detector in the prior art with tension detecting apparatus, and structure is simpler, compact and reasonable.
Below in conjunction with drawings and Examples the utility model is described in further detail.
