Description
Technical field
The present invention relates to the looping mechanism in a kind of bearded needle warp knitting machine knitting mechanism, particularly relate to the presser in looping mechanism.
Background technology
Existing warp knitting machine is divided into groove pin warp knitting machine, latch needle warp knitting and bearded needle warp knitting machine.For bearded needle warp knitting machine, what its knitting needle used is crochet hook, crochet hook is in lopping motion process, after sley bar completes its pad yarn, realize before lasso and knocking over, must push the pin notch portion of crochet hook, by strain, crochet hook pin mouth is sealed, to avoid yarn to slip in crochet hook pin mouth, thereby make the yarn on crochet hook realize smoothly lasso.The mechanism of pushing the distortion of crochet hook pin mouth on bearded needle warp knitting machine is presser.
The parts that push crochet hook in presser are pressing pieces, and pressing piece is the final Motor execution part of presser, and its motion requires to have forms of motion and a motion large young waiter in a wineshop or an inn aspect.In pressing piece and crochet hook contact process, namely push in crochet hook process and should keep in touch certain hour.From the forms of motion of pressing piece is required, extreme position in motion rests for some time, so, the forms of motion of pressing piece requires as linear reciprocating motion and has the motion in certain hour to rest in a limit of sports record position (position of turning back) of pressing, and only has instantaneous dwell (turning back at once) in another limit of sports record position.The motion size requirements of pressing piece is mainly the traverse of linear reciprocating motion, generally in 10～20mm left and right.
As shown in Figure 3, the presser of existing bearded needle warp knitting machine adopts plane eight-bar linkage to realize pressing action, it utilizes coupler-point curve characteristic on primary crank linkage to control the motion of pressing piece, this mechanism is complex structure not only, and pressing piece do not rest process in limit of sports record position, cannot meet the motion requirement of pressing piece, therefore, the effect of pressing is undesirable, has snagging, has greatly affected the quality of fabric.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of not only simple in structure, and pressing piece has in limit of sports record position the process of resting, thereby can guarantee the presser of the bearded needle warp knitting machine of fabric quality.
For solving the problems of the technologies described above, the present invention adopts a kind of like this presser of bearded needle warp knitting machine, comprise pressing piece, pressing swing arm and be arranged on rotationally the fuel tank main shaft in warp knitting machine fuel tank, described pressing piece is fixedly mounted on the upper end of described pressing swing arm, the lower end of described pressing swing arm is fixedly connected with the lopping balance staff of warp knitting machine looping mechanism, and this presser also comprises eccentric wheel, eccentric bushing connecting rod, triangle rocking bar and connecting rod; Described eccentric wheel is fixedly mounted on described fuel tank main shaft, the lower end of described eccentric bushing connecting rod is sleeved on described eccentric wheel, the lower end of the upper end of eccentric bushing connecting rod and described triangle rocking bar is rotationally connected, the upper end of described triangle rocking bar and the lower end of described connecting rod are rotationally connected, the shaft of described triangle rocking bar and the frame of warp knitting machine are rotationally connected, and the shaft of the upper end of described connecting rod and described pressing swing arm is rotationally connected.
As a kind of preferred embodiment of the present invention, described pressing piece is provided with oval hole, and the upper end of described pressing swing arm is provided with screw, and described pressing piece is fixedly mounted in described pressing swing arm by the screw that penetrates oval hole and be screwed into described screw.
In the present invention, between the lower end of described eccentric bushing connecting rod and described eccentric wheel, be provided with bearing, the lower end of this eccentric bushing connecting rod is contained on described eccentric wheel through described bearing holder (housing, cover).
Adopt after said structure, the present invention has following beneficial effect:
The present invention passes through by eccentric wheel, first group of crank and rocker mechanism that eccentric bushing connecting rod and triangle rocking bar form with by triangle rocking bar, second group of double rocker mechanism series connection that connecting rod and pressing swing arm form, and utilize two groups of linkages to be co-located near the relation in dead-centre position, be that pressing piece is when limit of sports record position, connecting rod and triangle rocking bar are similar to conllinear, therefore, when moving to extreme position, pressing piece have the motion in certain hour to rest, like this when sley bar completes pad yarn before realizing lasso and knocking over to crochet hook, pressing piece has completed the extruding to crochet hook pin notch portion, by strain, crochet hook pin mouth is sealed, make the yarn on crochet hook can realize smoothly lasso, thereby avoided snagging, guaranteed fabric quality.
The position of pressing piece of the present invention in pressing swing arm can be finely tuned by oval hole and screw, thereby guaranteed better the pressing effect of pressing piece on the whole fabric width of machine.
Presser of the present invention is easy to adjust, only needs by adjusting the long relation of bar in two groups of linkages, can make the pivot angle scope of movement output part pressing swing arm meet better the motion traverse requirement of pressing piece.
Presser of the present invention adopts the planar linkage mechanism of two-stage series connection, and simple in structure, cost is low, and can be applicable to higher running speed.
