Abstract

The utility model discloses a knitting needle for a full-automatic computerized flat knitting machine, comprising a front needle bar and a rear needle bar with different thicknesses and connected into a whole, wherein a step is formed at the connecting position of the front needle bar and the rear needle bar; a needle hook and a needle tongue which is matched with the needle hook are formed at the front end of the front needle bar; a needle heel and a needle tail are formed at the rear end of the rear needle bar; a bulge is arranged on the front needle bar between the step and the needle tongue; and the bulge and the needle tongue are positioned at the same side on the front needle bar. When a coil is raised by the needle tongue and falls on the step where the front bar and the rear needle bar are connected, shifting phenomenon occurs; the shifting is blocked by the additionally arranged bulge, while another knitting needle runs along the original path, and the next coil can not be hooked by the needle hook, therefore, redundant thread heads can not appear, and further, the yield of knitted fabric is greatly improved.

Description

The full-automatic computer cross weaving needle

Technical field

The utility model relates to the computer flat knitting machine assembly, a kind of improved full-automatic computer cross weaving needle of more specifically saying so.

Background technology

Knitting needle, a kind of main loop-forming element on the flat machine is made through machining by steel wire or steel band, is used for yarn being woven into coil and making coil string cover connect into knitted fabric.

Use the cross weaving needle of many knitting needles such as Chinese patent CN00246057.2 in the market, it comprises knitting needle front portion of being made up of bar 3 before pinhock 1, needle latch 2, the pin and the knitting needle rear portion of being made up of bar behind the pin 4, pin heel 5, backshank 6, and the thin form of coupling specification is stipulated at anterior ratio and the knitting needle rear portion of adopting of knitting needle.

Above-mentioned knitting needle has individual defective in the middle of the practical application, two knitting needles are located at respectively on needle plate triangular in shape two central planes of cross section, after the knitting needle pinhock 1 on the central plane wherein is woven into yarn one coil 7, choose by needle latch 2 and to fall the step place that bar 3 links to each other with bar 4 behind the pin before the pin, connect into knitted fabric by this coil 7 of the past of knitting needle pinhock 1 hook on another central plane and last coil 7 string covers again, needle latch 2 is chosen coil 7 and can be occurred being shifted after falling bar 3 before the pin and step place that bar 4 behind the pin links to each other in the middle of the real work, coil 7 is upwards sliding as shown in Figure 1, knitting needle on another central plane is still according to original track walking, its pinhock can be walked next coil 7 by hook, so unnecessary the end of a thread can occur, the knitted fabric that comes out has just become substandard products.

The utility model content

The purpose of this utility model is to overcome and has defective on the prior art knitting needle structure and cause weaving the high deficiency of defect rate, and a kind of full-automatic computer cross weaving needle this defective, that reduced the knitted fabric defect rate that remedies is provided.

In order to achieve the above object, the utility model is to realize by following purpose: a kind of full-automatic computer cross weaving needle, comprise and connect before the pin that thickness integratedly do not wait bar behind the bar and pin, the bar junction forms a step behind preceding bar of pin and the pin, the needle latch that the bar front end forms a pinhock and matches with pinhock before described pin, rod rear end forms a pin heel and a backshank behind described pin, it is characterized in that, form a projection before described pin on the bar between described step and described needle latch, this projection and described needle latch are positioned at homonymy on the preceding bar of pin.When needle latch coil is chosen and the displacement situation to be occurred behind bar and the step place that bar behind the pin links to each other before falling pin, the projection that this displacement is set up is kept out, another knitting needle is walked according to original track, its pinhock just can not walked next coil by hook, and this coil is colluded away in assurance, just unnecessary the end of a thread can not occur, make the knitted fabric yield rate promote greatly.

As preferably, described projection to described needle latch before pin the distance between the pin joint on the bar greater than the length of needle latch.If instead the projection to described needle latch before pin the distance between the pin joint on the bar less than the length of needle latch, the zone of action that projection will limit needle latch, cause another knitting needle defective, lose more than gain, therefore will guarantee the zone of action that projection does not limit needle latch, the distance between the pin joint on the bar must be greater than the length of needle latch before pin to described needle latch for projection.

As preferably, described height of projection is less than described shoulder height.The height of projection is too high, and coil just is not easy to be chosen by needle latch and falls.

Beneficial effect: when needle latch coil is chosen and the displacement situation to be occurred behind bar and the step place that bar behind the pin links to each other before falling pin, the projection that this displacement is set up is kept out, another knitting needle is walked according to original track, its pinhock just can not be hooked to next coil, just unnecessary the end of a thread can not occur, make the knitted fabric yield rate promote greatly.

Description of drawings

Fig. 1 is the woven condition schematic diagram of original technology knitting needle;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is a woven condition schematic diagram of the present utility model.

Among the figure: 1-pinhock, bar before the 2-needle latch, 3-pin, bar behind the 4-pin, the heel of 5-pin, 6-backshank, 7-coil, 8-projection.

The specific embodiment

Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.

Embodiment 1: as shown in Figure 2, a kind of full-automatic computer cross weaving needle, comprise and connect before the pin that thickness integratedly do not wait bar 4 behind the bar 3 and pin, bar 4 junctions form a step behind preceding bar 3 of pin and the pin, the needle latch 2 that bar 3 front ends form a pinhock 1 and match with pinhock 1 before pin, bar 4 rear ends form pin heel 5 and one backshank 6 behind pin, form a projection 8 before pin on the bar 3 between described step and needle latch 2, and this projection 8 is positioned at homonymy on the preceding bar 3 of pin with needle latch 2.The projection 8 to needle latch 2 before pin the distance between the pin joint on the bar 3 greater than the length of needle latch 2.Projection 8 height are less than described shoulder height.

Use: as shown in Figure 3, two knitting needles are located at respectively on needle plate triangular in shape two central planes of cross section, after the knitting needle pinhock 1 on the central plane wherein is woven into yarn one coil 7, choose by needle latch 2 and to fall the step place that bar 3 links to each other with bar 4 behind the pin before the pin, again by knitting needle pinhock 1 hook on another central plane in the past this coil 7 connect into knitted fabric with last coil 7 string covers.

Needle latch 2 is chosen coil 7 and can be occurred being shifted after falling bar 3 before the pin and step place that bar 4 behind the pin links to each other in the middle of the work, the projection 8 that this displacement is set up is kept out, another knitting needle is walked according to original track, its pinhock 1 just can not be hooked to next coil 7, just unnecessary the end of a thread can not occur, make the knitted fabric yield rate promote greatly.
