[0033] like Figure 1-13As shown, a machine needle assembly of a machine needle butler includes a machine needle assembly, wherein the machine needle assembly includes a needle clamp base 1, a needle clamp assembly 2 and a driving mechanism 3, the needle clamp assembly 2 is arranged above the needle clamp base 1, the needle clamp assembly 2 has a longitudinally arranged needle groove 21, a machine needle puller 4 is arranged between the bottom of the needle clamp assembly 2 and the needle clamp base 1, the middle part of the machine needle puller 4 is pivotally connected to the needle clamp base 1, the needle clamp base 1 has an active plane 11 for the machine needle puller 4 to move, and the machine needle puller 4 can move the needle groove 21 The lower needle opening is closed, a needle removal groove 41 is provided on the needle puller 4, and a lower needle groove 15 that passes through the movable plane from top to bottom is provided on the movable plane 11. The needle removal groove 41 is provided at the front of the needle puller 4, and the rear of the needle puller 4 is connected to the driving mechanism 3. The rear end of the needle puller 4 is connected to the output end of the driving mechanism 3 through the tension spring 5. A reset spring 6 is also provided between the needle puller 4 and the needle clamp base 1. The reset spring 6 and the tension spring 5 exert forces on the needle puller 4 in opposite swing directions.

[0034] The driving mechanism 3 drives the needle puller 4 to switch between the lower needle opening and of the needle groove 21. The needle clamp base 1 is also provided with a connecting seat 12 and a blocking part 13 which are higher than the active plane on both sides of the active plane. The connecting seat 12 and the blocking part 13 limit the swinging angle of the needle puller 4 and ensure that the needle removal groove 41 is aligned with the lower needle opening or the lower needle groove 15 of the needle groove 21.

[0035] The lower part of the needle clamp assembly 2 is fixedly connected to the connecting seat 12, and a gap is left between the bottom surface of the needle clamp assembly 2 and the movable plane for setting the machine needle puller 4; the machine needle puller 4 has different top surface heights on both sides of the needle removal groove 41, and a gap is left between the lower side of the top surface and the bottom surface of the needle clamp assembly 2; the height difference of the top surfaces on both sides of the needle removal groove 41 is about 0.5mm; when the needle removal groove 41 corresponds to the lower needle opening, the higher side of the top surface on both sides of the needle removal groove 41 is close to the lower needle groove 15, and the lower side of the top surface is away from the lower needle groove 15.

[0036] When the utility model is working, the driving mechanism 3 drives the eccentric arm to rotate to the farthest end of the pick, and the eccentric arm will drive the tension spring 5 to pull the front part of the needle puller 4 from the side of the blocking part 13 to the connecting seat 12. When the needle removal groove 41 is aligned with the lower end of the needle groove 21, the needle at the lower end of the needle groove 21 automatically falls into the needle removal groove 41; at this time, the eccentric arm rotates to the nearest end of the needle puller, and the tension spring is reset and relaxed. At the same time, the reset spring of the needle puller moves the front part of the needle puller 4 from the connecting seat 12 to the side of the blocking part 13. When the needle removal groove 41 is aligned with the lower needle groove 15, the needle is inserted.

[0037] Since the height difference of the top surfaces of the needle puller 4 on both sides of the needle removal groove 41 of the utility model is about 0.5mm, and the high-speed sewing machine needle is a high-precision item, and the surface smoothness of the needle is very high, during the research and development, the research and testing showed that the needle puller groove is 2.0mm, and the heights of the pullers on both sides are made different. Looking from the front to the front, the left side is 2.0mm high and the right side is 1.5mm high. When the needle puller moves with the needle, the lower side of the puller will not form an angle with the lower needle mouth of the needle groove, thereby avoiding damage to the needle and needle jam.

[0038] Furthermore, the utility model is provided with an anti-stuck slot hole 14 on the movable plane 11, and the anti-stuck slot hole 14 is located below the rear end of the lower needle opening of the needle slot 21. The anti-stuck slot hole 14 is connected with the lower needle slot 15 to form a P-shaped needle slot. In the machines currently on the market, due to improper operation by the administrator when replenishing the needle, the machine needle falls vertically into the needle group slot, causing the needle to be stuck and the needle group to be removed. The structure of the utility model effectively solves this problem. If there is improper operation, the machine needle will fall from the slot hole 14, and will not remain vertically in the needle group slot to cause the needle to be stuck or the needle group to be removed.

[0039] Furthermore, the needle clamp assembly 2 of the utility model includes a needle clamp 22 and a needle clamp 23, which are fixedly connected to each other to form the needle groove 21 between the two needle clamps. A needle pressing piece 24 is placed in the needle groove 21, and a longitudinal guide groove 25 is provided on the side wall of the needle clamp 23. A connecting block 26 is provided on one side of the needle pressing piece 24, and the connecting block 26 is located in the guide groove 25. The connecting block 26 is connected to a counterweight block 27, and the counterweight block 27 is located on the outside of the needle clamp 23; a counterweight block handle 28 is fixedly connected to the counterweight block 27.

[0040] The utility model opens a groove on the left side of the needle clamp 2 and uses a combination of an internal needle presser and an external counterweight block, which fully saves space. In this way, the height of the needle presser is greatly reduced, so that a single needle group slot can store more machine needles; a counterweight block operating handle is added on the side to facilitate operation and installation.

[0041] Furthermore, the utility model fixes the needle clamp base 1 and the driving mechanism 3 on both sides of a connecting plate 7, and a needle clamp base inclination adjustment structure is arranged between the needle clamp base 1 and the connecting plate; the inclination adjustment structure includes an adjustment seat 8, the adjustment seat 8 is fixedly connected to the connecting plate 7, the needle clamp base 1 is hinged to the adjustment seat 8, and an angle adjustment screw is arranged at the hinge.

[0042] There are many types of machine needles on the market, with great differences in thickness, length and width. Our newly improved adjustable needle assembly can adjust the inclination of the needle clamp and cooperate with the pressure block to move the center of gravity of the needle forward, so that the needle and the needle clamp base are parallel. It is suitable for various different machine needles, has good versatility and smoother needle removal.
