A kind of yarn type jacquard warp of pressing
The present invention relates to a kind of warp knitting machine, especially a kind of yarn type jacquard warp of pressing, belongs to Weaving device field.
Press yarn type jacquard warp to refer to Jacquard jacquard attachment and yarn pressing mechanism, and yarn pressing mechanism can press yarn processing to Jacquard yarn, make fabric there is few sley bar Raschel looms of three-dimensional pattern effect.
The loop-forming element of pressure yarn type jacquard warp in the market have groove pin, nook closing member, knocking-over bit, sinker, sley bar, Jacquard sley bar and schlagblech.The sley bar of common this machine has Jacquard jacquard guide bar before being arranged as schlagblech, has chaining ground sley bar and inlaid thread ground sley bar after schlagblech.In machine running process, schlagblech moves up and down, and gauze broche line pressure is not made below latch needles to its lopping, and Jacquard sley bar is only made side direction transverse motion.Chaining ground sley bar after schlagblech and inlaid thread ground sley bar are not only made side direction transverse motion and are also moved back and forth.When schlagblech presses down, pendulum after sley bar needs, abdicates space, and when schlagblech rises, sley bar forward swing, can be hooked to yarn, then lopping while guaranteeing groove pin backswing.All sley bars after schlagblech need to move back and forth, and the machine serious vibration that is in operation, has limited the raising of machine operating speed like this.Its sley point of sley bar swing drives yarn swing together, produces like this tension force inequality of yarn, not only makes grey cloth cloth cover effect bad, but also easily occurs broken yarn phenomenon and reduced production efficiency.
The guide bar shogging mechanism of this class machine is all controlled by the floral disc of the decorative pattern mechanism of different model.Weak point: the ground organizational form of flower type is single, changes ground and need to change floral disc during organizational form, reorientates location inaccurate after dismounting again.Moreover the replacing time is long, operative employee's working strength is larger.The requirement on machining accuracy of floral disc itself is high, and price comparison is expensive, so the limitation of causing to the variation of flower type.
Cam in the transmission mechanism employing closed fuel tank of this class machine loop-forming element and connecting rod are controlled.Wherein cam link transmission mechanism, between cam and driven member is that line or point contact, and pressure is large, easy to wear, noise is large, inertia is large, and transmission speed is low, and has very large impact when motion, greatly reduce establishment speed and the stability of machine, cannot be suitable for braiding at a high speed, and processing and manufacturing difficulty, accuracy is low.
Because above structure cannot break through, press the speed of service of yarn type jacquard warp all lower, conventionally at 250-300 rev/min.
Summary of the invention
For solving the problem of above-mentioned existence, the invention provides a kind of yarn type jacquard warp of pressing, not only transmission mechanism all adopts eccentric rod gear, and all sley bars only do horizontal transverse motion, and traversing by servomotor control, and stable drive, the speed of service are fast.
The present invention is achieved through the following technical solutions, a kind of yarn type jacquard warp of pressing, it is with yarn pressing device and Jacquard jacquard guide bar, the transmission mechanism of described yarn pressing device and groove pin transmission mechanism, nook closing member transmission mechanism, knocking-over bit transmission mechanism all adopt eccentric ratio transmission mechanism control, similar machine adopts cam and connecting rod in closed fuel tank to control in the market, and the board speed of service is just difficult to improve like this.The eccentric rod gear of schlagblech of the present invention, groove pin, nook closing member, knocking-over bit is by the eccentric actuation movement being arranged on fuel tank main shaft, and eccentric is wherein eccentric cam or eccentric crankshaft.
The Jacquard jacquard guide bar of the pressure yarn type jacquard warp of technique scheme, is arranged on before schlagblech, and wherein Jacquard jacquard guide bar plays jacquard weave effect.Its ground sley bar, forms ground function of organization, jointly completes the braiding knitting cycle of fabric.
Further: press the jacquard guide bar of yarn type jacquard warp only to do transverse movement, schlagblech does pressure yarn motion up and down reciprocatingly, chaining ground sley bar after its schlagblech and inlaid thread ground sley bar are also only made transverse motion, because transmission mechanism makes to obtain Rational Arrangement with guide chase comb position by accurate calculating, in guide chase comb position, both reserved that schlagblech presses down, the rising space, the chaining sley bar energy lopping while having guaranteed again groove pin backswing after schlagblech.Machine is in operation to vibrate and reduces, and machine operating speed improves.Secondly, sley bar is only made transverse motion, and the yarn on its sley point is the state in even tension just, and grey cloth cloth cover is effective, is not prone to broken yarn phenomenon, improves through compiling efficiency.
Further limit: described all sley bars are all moved by its transverse reciprocating of servomotor control that is arranged on a side, traversing accurate, simple to operation.The all sley bars of servomotor control do transverse movement, and the ground organizational form variation of flower type, without again changing adjustment.
Adopt said structure, make to press the speed of service of yarn type jacquard warp to be improved, at least can reach 650 revs/min, high through compiling efficiency, ground organizational form variation.
