Abstract
The utility model relates to a needle picking device of a computer hosiery knitting machine, comprising a needle picking base, a needle picking rotary shaft, a needle picking rod, a needle picking bolt, a needle picking guidance plate and a spring; wherein, the needle picking rotary shaft is levelly and rotationally connected at the upper end of the needle picking base; the back end of the needle picking rod is vertically and rotationally connected on the needle picking rotary shaft through the needle picking bolt; the front end of the needle picking rod is provided with a needle picking neck; the needle picking rod goes through the needle picking guidance plate which is provided with a step needle picking stroke groove; the needle picking base is connected with a middle position of the needle picking rod near the needle picking rotary shaft through the spring; the needle picking neck is in the shape of a step and the width of the bottom surface of the step is exactly the thickness of a stitch; the opposite side of the needle picking neck is of an arc shape; the needle picking rod is in soft touch rather than hard touch with the stitch in the needle picking process to prevent the stitches from being broken. The needle picking device accurately picks up only one needle once and is high in needle picking precision with needle picking power which comes from the reciprocating rotation of a needle barrel.
Description
Technical field
The utility model belongs to the computer stocking technical field, and particularly needle device is chosen in the computer stocking braiding.
Background technology
When hosiery machine is followed with undertoe in knit sock, syringe is done the rotating reciprocating motion and is woven, and only need the pin number of half to weave, both sides have a pin will withdraw from braiding so whenever make a round trip, withdraw from the pin of braiding and finish, choose needle device and must accurately the pin that withdraws from braiding be provoked by choosing needle device.Rise cam is driven by external impetus can be along the upper and lower vertical motion in syringe edge, and the rise cam that moves upward the then position of deactivating moves downward and then enters the operating position.Rise cam in working order, directly the stitch in the contact movement severs stitch easily, and motion is inconvenient, precision is difficult to control, breaks down easily.
Summary of the invention
The technical problems to be solved in the utility model is: had needle device now and severed stitch easily, inflexible technical problem of moving, the technical problem that the withdrawal of needle precision is not high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: needle device is chosen in the computer stocking braiding, it is characterized in that: comprise and choose the pin pedestal, choose the pin rotating shaft, needle-pick bar is chosen the pin bolt, choose needle guide plate and spring, choose the pin rotating shaft and horizontally rotate to be connected and choose pin pedestal upper end, the needle-pick bar rear end vertically is rotatably connected on and chooses on the pin rotating shaft by choosing the pin bolt, and the needle-pick bar front end is provided with chooses the pin draw-in groove; Needle-pick bar passes chooses the needle guide plate, chooses the needle guide plate and is provided with the step-like needle stroke groove of choosing, and the needle-pick bar middle part connects by spring near the position of choosing the pin rotating shaft chooses the pin pedestal.
As a kind of improvement of the present utility model, the described pin draw-in groove of choosing is step-like, and the width of step bottom surface is the thickness of a stitch just, and it is circular-arc choosing pin draw-in groove offside.
It comprises that is also chosen a pin adjustable plate, and this chooses the pin adjustable plate is a skewback, is arranged side by side with choosing the needle guide plate, regulates and chooses pin in the position of choosing on the needle guide plate.
Choose also to be provided with on the pin pedestal and choose the pin push rod, choose the pin push rod and be positioned at and choose pin rotating shaft one side, adjust needle-pick bar horizontal direction position.Choose the elongation of pin push rod, promote needle-pick bar and horizontally rotate, choose the pin draw-in groove away from the workspace.
When choosing needle device work, the pin draw-in groove of choosing of needle-pick bar front end blocks the stitch on the syringe in the rotation, under the effect of syringe rotary torsion, the stitch of motion drives needle-pick bar and rotates in the horizontal direction, needle-pick bar raises when stroke groove on the needle guide plate rotates in the horizontal direction according to the stroke of setting along choosing, so just, the stitch on the syringe is raised, stitch is also rotating away from the needle-pick bar front end simultaneously, when stitch is lifted to the height of middle corner angle, stitch also just breaks away from needle-pick bar automatically, needle-pick bar is got back to initial position under the effect of spring, finish and once choose the pin process.
Because spring action, needle-pick bar is not hard the contact with stitch in choosing the pin process, but soft contact prevents from stitch is severed.Simultaneously the utility model is only chosen a pin at every turn, and it is accurate to choose pin, and it is higher to choose the pin precision, chooses the reciprocal rotation of pin power resources in syringe.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, choose to be provided with above the pin pedestal 1 and choose pin rotating shaft 2, choose pin rotating shaft 2 by bolt 3 needle-pick bar 4 rear ends that are rotationally connected, needle-pick bar 4 both can have been done to horizontally rotate also can do up and down and rotated with respect to choosing pin pedestal 1.The middle part of needle-pick bar 4 is provided with aperture 5 near the position of choosing pin rotating shaft 2, and aperture 5 connects the spring upper end, and the spring lower end is fixed on chooses on the pin pedestal 2.Needle-pick bar 4 passes chooses needle guide plate 6, chooses the step-like needle stroke groove 7 of choosing is set on the needle guide plate 6, and needle-pick bar 4 is according to choosing the route motion that needle stroke groove 7 is set.Also be provided with one side by side and choose pin adjustable plate 8 with choosing needle guide plate 6, this chooses pin adjustable plate 8 can adjust needle-pick bar 4 in the position of choosing on the needle guide plate 6.The needle-pick bar front end is provided with chooses pin draw-in groove 4a, and this chooses pin draw-in groove 4a is step-like, and the bottom width of step is a stitch thickness.The offside 4b that chooses the pin draw-in groove is circular-arc.
Choose also to be provided with on the pin pedestal and choose the pin push rod, this is chosen the pin push rod and is controlled by cylinder, can promote needle-pick bar and rotate in the horizontal direction, when not needing to choose pin work, chooses the elongation of pin push rod and promotes the needle-pick bar rotation, makes the needle-pick bar front end away from the knitting needle stitch.
As shown in Figure 5, when choosing needle device and enter the workspace, stitch 110 on the syringe is just chosen pin draw-in groove 4a by the front end of needle-pick bar and is blocked, under the effect of syringe revolving force, stitch 110 drives the needle-pick bar horizontal movement, because the restriction that the motion of needle-pick bar also will be chosen the needle guide plate, so needle-pick bar moves upward along choosing the needle guide plate in horizontal movement, knitting needle is provoked, and the height of corner angle 111 has so just been finished and has once been chosen pin in sending into.
As shown in Figure 6, D is the high-order pin that withdraws from braiding, and C is the pin that low level is in woven condition, and first row is for choosing first reciprocal pin of pin program from the bottom up, and second row is second reciprocal pin, until the 16 back and forth.One of the every rotation of syringe is back and forth chosen the every limit of needle device and is just provoked 1 pin, and each reciprocal every limit just has 1 pin to withdraw from braiding, finishes until choosing the pin program.
