Description
Technical field
The utility model relates to a kind of knitting mechanism of warp knitting machine, particularly relates to the Schlagblech moving device in a kind of knitting mechanism of pressing 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 the yarn process requirement, guaranteeing product quality; When the pressure yarn sley bar of warp knitting machine as pressing yarn merchant card sley bar quantity more than two or press the yarn sley bar to arrange under the bigger situation in space; Because the pressure yarn degree of depth that requires is dark and require to press the yarn time shorter, therefore when pressing yarn speed less and can not satisfy pressure yarn speed technological requirement the time, the yarn that then is positioned at the groove pin pinhock can not in time be pressed down on the open stem and cause quality accident.
The Schlagblech moving device of existing pressure yarn type warp knitting machine; Like Chinese invention patent ZL98118606.8, name is called the prospectus with chopper bar bed warp knitting machine and discloses a kind of Schlagblech moving device, and this device comprises the rotating shaft that is installed in rotationally on the warp knitting machine frame; Be fixedly mounted on the eccentric wheel in the said rotating shaft; The eccentric bushing connecting rod, the V-type connecting rod is pressed yarn connecting rod and fork; One end of said eccentric bushing connecting rod is sleeved on the said eccentric wheel, and an end of the other end and said V-type connecting rod is rotationally connected; The upper end of the other end of said V-type connecting rod and said pressure yarn connecting rod is rotationally connected, and the shaft of this V-type connecting rod is installed on the warp knitting machine frame rotationally; Schlagblech is fixedly mounted on the lower end of said pressure yarn connecting rod; The shaft of one end of said fork and said pressure yarn connecting rod is rotationally connected, and the other end is installed on the warp knitting machine frame rotationally; Rotating shaft is rotated by the fuel tank main shaft drives of warp knitting machine.The Schlagblech moving device of this structure is in series by a crank and rocker mechanism and a parallel-crank mechanism; 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 to cause taking place quality accident thereby can not satisfy.
Chinese invention patent ZL200810156904.8; The prospectus that name is called fall plate moving apparatus of warp knitting machine also discloses a kind of structure; 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.The Schlagblech moving device of this structure; 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.
Summary of the invention
It is bigger in the pressure yarn speed of pressing the yarn stage that the technical problem that the utility model 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 Schlagblech moving device simple in structure.
For solving the problems of the technologies described above; The utility model adopts a kind of like this fall plate moving apparatus of warp knitting machine, comprises the rotating shaft that is installed in rotationally on the warp knitting machine frame, is fixedly mounted on the eccentric wheel in the said rotating shaft; The eccentric bushing connecting rod is pressed the yarn connecting rod and first fork; One end of said eccentric bushing connecting rod is sleeved on the said eccentric wheel; The shaft of one end of said first fork and said pressure yarn connecting rod is rotationally connected, and the other end is installed on the warp knitting machine frame rotationally; Said schlagblech is fixedly mounted on the lower end of said pressure yarn connecting rod; Said rotating shaft is rotated by the fuel tank main shaft drives of warp knitting machine, and this Schlagblech moving device also comprises second fork, first connecting rod and second connecting rod; One end of said second fork and the shaft of said eccentric bushing connecting rod are rotationally connected, and the other end is installed on the warp knitting machine frame rotationally; The other end of the right-hand member of said first connecting rod and said eccentric bushing connecting rod is rotationally connected; 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 pressure yarn connecting rod is rotationally connected, and the shaft of this second connecting rod is installed on the warp knitting machine frame rotationally.
The shaft of the other end of said first fork of the utility model, the other end of said second fork and second connecting rod is installed on the warp knitting machine frame through bearing pin respectively rotationally; Said rotating shaft drives rotation by the fuel tank main shaft of warp knitting machine through synchronizing wheel, synchronous belt drive mechanism.
After adopting such structure; Because the utility model Schlagblech moving device also is provided with second fork, first connecting rod and second connecting rod; When braiding; The plane eight-bar linkage that is made up of eccentric wheel, rotating shaft, eccentric bushing connecting rod, second fork, first connecting rod, second connecting rod, pressure yarn connecting rod and first fork through the fuel tank main shaft drives is realized the rectilinear motion up and down reciprocatingly and the front and back translation 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 the whole telecontrol equipment of the utility model 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.In addition; The pressure yarn speed of schlagblech adjustment is also more convenient in the utility model, only needs to change second 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 second 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.
