BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic circular knitting machine, which is a kind of textile machine. More particularly, the circular knitting machine is in contact with each other by forming symmetrically inclined portions on both sides of the finger tip of the needle tip device driven by each series of control systems by software. Can rotate the cylinder in both directions to select the knitting needles to form a variety of patterns, simplifying the internal configuration of the needle needle case to prevent deformation of each limiting jaw gap due to internal friction when the finger flows up and down It relates to an electronic circular knitting machine.

Knitting machine is a device which knits a cylinder jack disposed in a cylinder groove around a cylinder with various types of knitting needles required by an electronic signal input to a computer, and knits it without permission. The knitting machine can be classified into a flat knitting machine and a circular knitting machine.

Conventional flat knitting machines are mainly intended for the production of fabrics, and in contrast to the normal knitting structure when finishing the sleeve end or the rubber end of the body in the sweater section, the rib knitting structure of the wrinkled form is well adopted. Two body structures were adopted. However, the flat knitting machine of such a structure had a problem of very low productivity. In order to solve such a problem with the conventional flat knitting machine, in recent years, a circular knitting machine in which a cylinder, a cam, etc. are continuously rotated at high speed is used.

1 is an overall schematic view showing a knitting function of a general circular knitting machine, FIG. 2 is a structural diagram showing an operating state of a general push-in type needle tip device, FIG. 3 is a perspective view showing a needle tip device according to the prior art, and FIG. 4 is a schematic side cross-sectional view showing a prior art needle device.

Circular knitting machine according to the prior art, as shown schematically in Figure 1, a plurality of upper cams (not shown) and a slope 187, a drive provided in the upper portion of the cylinder 180 that rotates in one direction And a motor 145 ', a lower cam 181, and the like.

 On the outer circumferential surface of the cylinder 180, a plurality of cylinder grooves 182 are formed along its major axis, and the knitting needle 185 is arranged to be swingable between each cylinder groove 182, and the knitting needle 185 The lower end of the cylinder jack 183 is arranged to contact. In addition, the lower cam 181 of the cylinder is fixedly arranged at a predetermined interval along the circumference at the lower portion of the cylinder 180, a plurality of upper cams are installed at the upper end of the cylinder 180 is arranged at a predetermined interval, A road 187 for guiding the seal 186 is provided.

Brief description of the knitting principle of the circular knitting machine is as follows.

When each knitting needle 185 on the rotating cylinder 180 is pushed upwards vertically with the aid of the cylinder jack 183 by the lower cam 181, the knitting needle 185 is raised above the cylinder 180 as a result. It protrudes. The loop of the thread 186 is made by giving the thread 186 drawn out of the bobbin 188 to the hook of the protruding needle 185. Then, one stitch Stich is formed by lowering the knitting needle 185 downward by the upper cam. Therefore, by selecting whether or not to move the knitting needle 185 up and down, it is possible to control the process to proceed to the next knitting process without stitching or stitching, it is possible to knit the desired knitted fabric.

In order to operate the knitting needle 185 as described above, the cylinder jack 183 is vertically disposed to contact the lower portion of the knitting needle 185. Then, the coupling between the cylinder jack 183 and the lower cam 181 is performed by using the needle tip 160 which operates according to the information output from the control unit 170 having a storage device storing the knitting procedure. By selectively performing, the up / down movement of the knitting needle 185 is controlled.

On the other hand, the needle tip device 160 is a device that accurately selects the needle 185 for high-speed rotation according to a pattern, and is greatly lifted up type (Lift-up Type) according to a driving method of a finger on the cylinder jack 183. ) And Push-in Type. The lift-up type is a method in which the butt needle 185 is driven by raising the butt 184 along the finger slope of the needle tip device 160. The push-in type pushes the finger of the needle tip device 160 by the butt 184. It is a method of driving the needle by contacting or detaching from.
