Description
Technical field
The present invention relates to a kind of knitting mechanism of warp knitting machine, particularly relate to a kind of many combs and press the Schlagblech moving device in the knitting mechanism of yarn type warp knitting machine.
Background technology
For warp knitting machine with schlagblech; The pressure yarn stage of control schlagblech is the traverse and the speed of depression phases; Especially pressing yarn speed is to satisfy the key of pressing yarn process requirement, assurance product quality, is pressing under the situation that the yarn degree of depth is dark and the pressure yarn time is short, if press yarn speed less; The yarn that then is positioned at the groove pin pinhock can not in time be pressed down on the open stem, so that can not satisfy and press the yarn process requirement and cause quality accident.
The Schlagblech moving device of existing pressure yarn type warp knitting machine; Like Chinese invention patent ZL200810156904.8; Name is called the disclosed a kind of structure of prospectus of fall plate moving apparatus of warp knitting machine; It comprises the fuel tank main shaft and the schlagblech of warp knitting machine; Said fuel tank main shaft is through identical transmission mechanism driven in common schlagblech motion more than two groups, and every group of transmission mechanism is in series by conjugate cam mechanism, first planar pivot four-bar mechanism, second planar pivot four-bar mechanism and slide block mechanism.This Schlagblech moving device; Because schlagblech relies on the appearance profile of conjugate cam to satisfy at the pressure yarn rate request of pressing the yarn stage fully; Pressing under the situation that the yarn degree of depth is dark and the pressure yarn time is short like this, the moving displacement curvilinear motion on the conjugate cam profile is very steep, and its speed and accelerating curve exist discontinuous or sudden change; And pressing the yarn stage bigger by the traverse of the telecontrol equipment of conjugate cam driving; Therefore there is great impact in this Schlagblech moving device when motion, greatly reduces the braiding speed and the stability of machine, can't adapt to braiding at a high speed.
Chinese invention patent ZL98118606.8; Name is called the prospectus with chopper bar bed warp knitting machine and also discloses a kind of Schlagblech moving device; This device is in series by a crank and rocker mechanism and a parallel-crank mechanism; Schlagblech is installed on the connecting rod of parallelogram, and whole device is through be with by the fuel tank main shaft drives synchronously.The Schlagblech moving device of this structure; On the one hand; In when braiding because schlagblech presses down and the average speed in two stages of rising equates basically and press yarn speed less; So pressing under the situation that the yarn degree of depth is dark and the pressure yarn time is short, the yarn that is positioned at the groove pin pinhock can not in time be pressed down on the open stem, presses the yarn process requirement thereby can not satisfy; On the other hand; Because the connecting rod of the parallel-crank mechanism in this telecontrol equipment is done translation, also does translation when schlagblech presses down, schlagblech can and interfere between each sley bar of its back when braiding like this; Therefore on such warp knitting machine; Generally take the part sley bar motionless, the structural configuration of schlagblech back sley bar swing can be swung to dodge schlagblech each sley bar of schlagblech back and is avoided interference when schlagblech presses down; But; Because the oscillating motion of each sley bar needs corresponding separately sley bar pendulous device and accomplishes; Therefore the complex structure of this Schlagblech moving device, especially the sley bar number is 18 when above, because this part swing sley bar quantity is many in multi-bar warp knitting machine; Weight is big, therefore can not adapt to braiding at a high speed.
Summary of the invention
It is bigger in the pressure yarn speed of pressing the yarn stage that the technical problem that the present invention will solve provides a kind of not only schlagblech; Thereby press the yarn process requirement than dark with pressing to satisfy under the situation of yarn time than weak point in the pressure yarn degree of depth; And whole device the time do not have impact in motion, can adapt to high speed and weave and multi-bar warp knitting machine Schlagblech moving device simple in structure.
For solving the problems of the technologies described above, the present invention adopts a kind of like this multi-bar warp knitting machine Schlagblech moving device, comprises connecting rod, is fixedly mounted on the schlagblech fairlead on the warp knitting machine frame, and the schlagblech mount pad that is slidingly connected with said schlagblech fairlead; The upper end of said schlagblech mount pad and the lower end of said connecting rod are rotationally connected, and the lower end is fixedly connected with schlagblech, and this Schlagblech moving device also comprises eccentric wheel, eccentric bushing connecting rod, fork, first connecting rod, second connecting rod and rotating shaft; Said eccentric wheel is fixedly mounted in the said rotating shaft; One end of said eccentric bushing connecting rod is sleeved on the said eccentric wheel, and the right-hand member of the other end and said first connecting rod is rotationally connected, and the shaft of this eccentric bushing connecting rod and the upper end of said fork are rotationally connected; The lower end of said fork is installed on the warp knitting machine frame rotationally; The right-hand member of said second connecting rod and the left end of said first connecting rod are rotationally connected, and the upper end of left end and said connecting rod is rotationally connected, and the shaft of this second connecting rod is installed on the warp knitting machine frame rotationally; Said rotating shaft is installed in rotationally on the warp knitting machine frame and is driven through synchronizing wheel, synchronous belt drive mechanism by the fuel tank main shaft of warp knitting machine and rotates.
The lower end of said fork and the shaft of second connecting rod are installed on the warp knitting machine frame through bearing pin respectively rotationally.
After adopting such structure; Because the plane eight-bar linkage that the present invention is made up of eccentric wheel, rotating shaft, eccentric bushing connecting rod, fork, first connecting rod, second connecting rod, connecting rod, schlagblech fairlead, schlagblech mount pad through the fuel tank main shaft drives is realized the rectilinear motion up and down reciprocatingly of schlagblech; When motion; The average speed of schlagblech in the process of pressing down is bigger; Can satisfy well press the yarn degree of depth dark with the pressure yarn process requirement of pressing under the shorter situation of yarn time, guaranteed fabric quality on the open stem thereby yarn in the groove pin pinhock can in time be pressed down to; Because whole telecontrol equipment of the present invention mainly is made up of linkage, therefore when motion, do not have impact again, greatly reduce the vibration and noise of warp knitting machine, improved the speed and the stability of warp knitting machine running, can adapt to braiding at a high speed better; And, because schlagblech the time is made rectilinear motion up and down reciprocatingly in braiding, interfere with each sley bar that is positioned at its back pressing down Shi Buhui; Therefore telecontrol equipment of the present invention need not baroque sley bar pendulous device; Make the simple in structure of this telecontrol equipment, install and easy to maintenance that cost is low.In addition; The pressure yarn speed of schlagblech is easy to adjust among the present invention, only needs to change fork and a position that is rotationally connected of eccentric bushing connecting rod shank in the crank and rocker mechanism that is made up of eccentric wheel, rotating shaft, eccentric bushing connecting rod and fork, and the coupler-point curve shape promptly changes; Thereby can adjust schlagblech easily and press down the average speed ratio with ascent stage; Thereby can be applicable to different warp knitting machine types better, to satisfy its different pressure yarn rate request, applicability is strong.
