[0013] Figure 2 It is a top view running track diagram of the horizontal cutting hair needle in the present utility model.

[0014] In the figure: 1 - horizontal cutting hair needle, 11 - yarn - hooking head, 12 - oblique cutting knife, 121 - yarn - cutting stop point, 2 - vertical knitting needle, A - first position, B - second position, C - third position, D - upper plate, D1 - first horse seat, D2 - first triangle, E - lower needle cylinder, E1 - second horse seat, E2 - second triangle, F - cylinder mouth position. Detailed Description of the Invention

[0015] As Figure 1 、 Figure 2 shown, the improved knitting needle guiding circular weft knitting machine includes a horizontal cutting hair needle 1, a horizontal needle - walking guiding mechanism, and a vertical needle - walking guiding mechanism. Its characteristics are that

[0016] At the outer - diameter end of the horizontal cutting hair needle 1, a yarn - hooking head 11 is processed by stamping. At the outer - diameter end of the horizontal cutting hair needle 1, an oblique cutting knife 12 is also processed by stamping. The inclined direction of the oblique cutting knife 12 is towards the inner - diameter direction, the cutting edge of the oblique cutting knife 12 faces the outer - diameter direction, and at one end of the oblique cutting knife 12 in the inner - diameter direction, a yarn - cutting stop point 121 protruding towards the outer - diameter direction is integrally formed by stamping. At the top edge of the inner - diameter end of the horizontal cutting hair needle 1, a tooth protruding upwards is integrally formed by stamping;

[0017] Above the upper plate D, a first horse seat D1 is suspended. The bottom surface of the first horse seat D1 is fastened with a first triangle D2 by screws. The bottom surface of the first triangle D2 is processed with a first rail groove by a numerical control milling machine. The first triangle D2 can guide the horizontal cutting hair needle 1 to perform horizontal forward / backward movement through the first rail groove;

[0018] The combination of the first horse seat D1 and the first triangle D2 forms a horizontal needle - walking guiding mechanism;

[0019] On the outer - diameter direction of the lower needle cylinder E, a second horse seat E1 is installed. The inner - diameter surface of the second horse seat E1 is fastened with a second triangle E2 by screws. The inner - diameter surface of the second triangle E2 is processed with a second rail groove by a numerical control milling machine. The second triangle E2 can guide the vertical knitting needle 2 to perform vertical up / down movement through the second rail groove;

[0020] The combination of the second horse seat E1 and the second triangle E2 forms a vertical needle - walking guiding mechanism.

[0021] As Figure 2As shown, when the horizontal cutting knife needle 1 runs to the first position A under the guiding action of the first rail groove of the first cam D2, the horizontal cutting knife needle 1 holds the yarn. Then the horizontal cutting knife needle 1 continues to run to the second position B. At this time, the vertical knitting needle 2 positions the yarn at the mouth position F of the lower cylinder E. Then the horizontal cutting knife needle 1 continues to run to the third position C. At this time, the vertical knitting needle 2 remains stationary, and the horizontal cutting knife needle 1 cuts the yarn at the third position C, completing a set of cyclic actions.
