Description
Technical field
The present invention relates to a kind of production method and device of needle entangled non-woven material with even stitches, belong to the acupuncture apparatus technical field.
Background technology
Needled punched nonwoven material is fiber reinforced, be that the pin fiber web that seamed edge such as triangle has a hook thorn carries out repeated localised puncture normally 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 and stays in the fiber web with the state of near vertical, fiber is tangled at the volley mutually and fiber web is produced certain compression, thereby made the needled punched nonwoven material of certain thickness, certain intensity.Pull-type or pressure lace curtaining formula clamping feed mechanism of the at present domestic pressure net for catching fish or birds that is used to process the eccentric wheel that generally driven through transmission mechanism by main motor without the fibroreticulate pre-needling machine of reinforcing, linkage, the needle plate that pricker is housed linkage under, the needle plate beam on the needle plate, the stripping web plate needle plate under and a holder web plate and a side that eccentric wheel drives and roller output mechanism constitute; The main needing machine overwhelming majority only joins the roller output mechanism and does not dispose clipping feed mechanism.Eccentric wheel connecting rod mechanism drives the needle plate that pricker is housed and moves up and down, reach the purpose of processed fiber web being implemented reinforcing, the stripping web plate is used to block fiber web, pricker is successfully withdrawed from from fiber web, the holder web plate works the relative distance effect that keeps between pricker and fiber web, makes pricker and fiber web keep a definite paracentesis depth.Needled punched nonwoven material has two important parameters, and promptly needling density and depth of needling rationally select for use above-mentioned two technological parameters can produce all kinds of different cultivars, the different needled punched nonwoven material that requires.So-called needling density, the theoretical acupuncture number (unit: thorn/mm that is meant that fiber web is subjected on unit are
2); So-called depth of needling is the length (unit of giving prominence to behind the pricker puncture fiber web outside fiber web: mm).Transporting velocity when at present both at home and abroad the needing machine fiber web produced of each needing machine manufacturer is by the acupuncture district all is at the uniform velocity mobile, punch frequency also is constant in normal operation in theory, but in the production of reality, existing all kinds of needing machine exists can not remain the uniform needle tracking of needled punched nonwoven material, also exist because of 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.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, has caused the inhomogeneous of drawing-off.
Summary of the invention
The objective of the invention is to keep producing the deficiency of the uniform needled punched nonwoven material of all-the-time stable needle tracking because of its structural factor has determined the needled punched nonwoven material production equipment, a kind of production method and device of needle entangled non-woven material with even stitches is provided at existing all kinds of needing machines.
The objective of the invention is to be achieved through the following technical solutions, a kind of production method of needle entangled non-woven material with even stitches, the pricker that comprises pre-needling machine and main needing machine is characterized in that in the clearance-type puncture motion of under its main driven by motor fiber web being done described production method also comprises the step motion after pricker withdraws from fiber web that fiber web is done between pre-needling machine and main needing machine stripping web plate and holder web plate.
A kind of process units of needle entangled non-woven material with even stitches, comprise pre-needling machine and main needing machine, the pressure of linkage, the needle plate that pricker is housed under the linkage, the needle plate beam on the needle plate, the stripping web plate under the needle plate and the holder web plate and a side of the eccentric wheel that pre-needling machine is driven through transmission mechanism by main motor, eccentric wheel drive is enlisted the services of pull-type or is pressed lace curtaining formula clamping feed mechanism and roller output mechanism; The roller output mechanism of the linkage of the eccentric wheel that main needing machine is driven through transmission mechanism by main motor, eccentric wheel drive, the needle plate that pricker is housed under the linkage, the needle plate beam on the needle plate, the stripping web plate under the needle plate and a holder web plate and a side is characterized in that described device also comprises the control system of being made up of Programmable Logic Controller, servo controller and touch-screen; Described main needing machine is provided with roller clamping feed mechanism, and the pressure of described pre-needling machine is enlisted the services of pull-type or pressed the roller clamping feed mechanism and the roller output mechanism of lace curtaining formula clamping feed mechanism and roller output mechanism and described main needing machine all to adopt driven by servomotor; The sensing element that is provided with on the transmission mechanism main shaft of main motor in pre-needling machine, the main needing machine connects the input of servo controller, the output servo motor termination of servo controller.
The present invention is the improvement to existing needled punched nonwoven material production method and device, it is inhomogeneous to overcome the needle tracking that the continuous motion by the acupuncture district of the puncture campaign of existing needing machine pricker clearance-type and fiber web brings, take the step motion of fiber web after pricker withdraws from fiber web, pass through computer Simulation in advance, find out nonwoven material for obtaining even needle tracking in same cloth pin mode, theoretical needle tracking under the asynchronous input state, distribution according to inhomogeneous theoretical needle tracking, the establishment corresponding control programs, the acupuncture drop point site of crossing thin or overstocked place is adjusted, make the theoretical needle tracking under this stepping amount be tending towards even, then by clipping feed mechanism of configuration and roller output mechanism, to input, output mechanism configuration servomotor, under the effect of control program, implement the gap output of control, reach the even of web surface needle tracking, for solve former needing machine in continuous output procedure when pricker is not also extracted out from fiber web, the acupuncture district with export the draw problems that fiber web between towing point can be subjected to brute force.Evenly the output movement of needle tracking needing machine is implemented stepping control, implement Synchronization Control with the main motor of acupuncture campaign simultaneously, driven by servomotor after pricker withdraws from fiber web and indentation stripping web plate working surface, output movement finishes when pricker falls back on peak and begins next acupuncture motion cycle.Input motion and output movement are synchronous, and with the minimum tension of guaranteeing transfer movement and the accurate control of stepping amount, the present invention is applicable to thorn under the single needle plate, goes up thorn; The crosspointer plate stings down, upward thorn, dystopy are stung thorn, coordination intersection thorn, coordination; Make up acupuncture etc., help improving the quality of needled punched nonwoven material, have remarkable economic efficiency.
