Description
Technical field
The present invention relates to a kind of regulating device for linear speed of needle loom on needling production line, belong to the acupuncture apparatus technical field.
Background technology
Needle point method is the most general in the nonwoven material production technology, the most a kind of production method, because its processing technology is simple, flow process is short, the equipment combination is flexible, the product type that adapts to is many, the utilization field is wide, equipment investment is few, plurality of advantages such as the construction period is short are so the acupuncture production method is still the present and the future's fast development, a kind of topmost nonwoven material production technology that does not wane of containing of a specified duration.
The needle point method operation principle is to be that triangle and seamed edge have puncturing repeatedly at fiber web of hook thorn with the cross section.Hook thorn on the pricker just is with the some fibre of web surface and nexine to pass fibrage with pricker, thorn is forward because of the hook thorn during needle pickup, the fiber that is brought into breaks away from the hook thorn to be stayed in the fiber web with the state of near vertical, makes fiber tangle mutually to reach at the volley fiber web is produced certain compression.Thereby made have certain thickness, the needled punched nonwoven material of certain intensity.
Characteristics such as the nonwoven material of reinforce producing with needle point method has that transparency is good, strainability, mechanical performance are good, be widely used in multiple industries such as making geotechnological material, filtering material, architectural waterproof material, hygienic material, automotive trim, home decoration material, synthetic leather base material, felt with and live and use non-woven fabric material.Acupuncture class nonwoven material accounts for 40% of whole nonwoven material total amount.
In non-weaving cloth is produced, fabric is from entering first unit machine, and is middle through one or more unit machine, after finishing a series of physical actions, come out to become semifinished or finished goods from the last unit machine, the machine of these a series of complete uses is called production line.
At first to satisfy fabric energy stepless speed regulation in running for the transmission design of production line, and equate (promptly satisfying the requirement of Synchronous Transmission) with the speed of each unit machine.In addition, the suffered tension force of fabric also should be less and even.
At present, the mode of control production line Synchronous Transmission mainly contains following several:
(1) segmentation collective transmission refers to adopt a variable-speed motor, guarantees synchronous speed ratio with stiff transmission (major axis, gear, sprocket wheel etc.).In order to adapt to the process adjustments requirement, also can install stepless speed changing mechanism additional and carry out the trace adjusting.Because the rotary inertia and the moment of resistance of unit, front and back are all different, when driving starting, the lifting speed of a motor vehicle or parking stopper, each unit speed can not be in full accord, thereby produce the excessive or relaxation of fabric tension.
(2) multiple-unit machine packet synchronization transmission refers to that every unit machine has independent variable-speed motor transmission, and the synchronous dependence speed regulation control mechanism of each electromotor velocity is controlled automatically.Speed regulation control mechanism can be utilized the variation of fabric tension, the variation of fabric position or the variation of fabric weight, and control variable-speed motor rotating speed guarantees fabric threads speed synchronization in the production line.Wherein tension type fabric threads speed adjusting device is used in dyeing line in a large number, it is the variation that utilizes this parameter of operation fabric warp-wise tension force, convert the device of electric signal to, except playing the synchronous variable-speed effect, also have the effect that keeps the permanent tension force of fabric.
(3) many fabric guide rolls transmission of unit machine such as guide roll type drying machine in the production line can be adopted each fabric guide roll of the independent transmission of AC torque motor.This torque motor is the software feature of dependence itself, makes itself and last location organizational security hold roughly synchronous operation.
At present, the acupuncture production line that domestic many no spinning equipment enterprise produces, it is adjusted synchronously is to rely on the frequency converter motor of every unit machine to adjust manually separately, makes each unit machine linear velocity roughly the same.Each unit machine produces velocity variations because of the fluctuation of operating load, cause between each unit machine speed asynchronous, make whole production line reach technological requirement, usually electric adjustment personnel's field adjustable experience requires high especially, often identical machine is completely different because of electric adjustment personnel's difference performance, if even if the high-caliber commissioning staff of producing high-grade fabric also is difficult to really reach requirement.
Owing to determined by the operation principle of needing machine, thorn is a clearance-type at fibroreticulate puncture campaign.And the conveying haulage gear of active type determines that fiber web is continuous by the speed in acupuncture district.Like this, when pricker was not also extracted out from fiber web, the fiber web between acupuncture district and output towing point was subjected to powerful drawing-off effect.Certainly pricker has relaxed partly drafting force towards the elastic yield of outbound course, but has caused the inhomogeneous of drawing-off again from the acupuncture district to the difference of the suffered tractive force of the fiber web towing point.The result is that the mechanical and physical performance to needled punched nonwoven material exerts a certain influence.
