[0030] In order to better understand the technical scheme of the utility model, the following more detailed elaboration is carried out in combination with the embodiment.

[0031] The warp knitting machine yarn feeding depth adjusting mechanism, including support 10 and rotatably arranged on the swing shaft 30 of support 10, support 10 is equipped with along the horizontal direction setting shaft hole 11, swing shaft 30 is arranged in shaft hole 11, swing shaft 30 along the horizontal direction setting.In the warp knitting machine, the guide bar holder 60 is fixedly installed on the swing shaft 30, the guide bar holder 60 swings synchronously with the swing shaft 30, a plurality of guide bars are installed on the guide bar holder 60, and the guide bar swings together with the guide bar holder.

[0032] In this invention, a bearing 50 and an adjusting sleeve 20 are provided between the hole wall of the shaft hole 11 and the swing shaft 30. The adjusting sleeve 20 is fitted over the swing shaft 30 and can be rotated relative to the swing shaft 30. The bearing 50 is fitted over the adjusting sleeve 20 and includes an inner ring and an outer ring that can rotate relative to each other. The outer ring is installed in the shaft hole 11, and the inner ring is fitted over the adjusting sleeve 20. In this invention, the circle containing the outer wall 201 of the adjusting sleeve is not concentric with the circle containing the inner wall 202 of the adjusting sleeve. An adjusting wall is formed between the outer wall 201 and the inner wall 202 of the adjusting sleeve, which can adjust the height of the swing shaft 30. Because the circle containing the outer wall 201 and the inner wall 202 of the adjusting sleeve are not concentric, the thickness of the adjusted wall gradually changes. The difference in thickness corresponds to the adjustable height value of the swing shaft 30. When the thicker wall portion is located at the lower part of the shaft hole 11, the pendulum shaft 30 is raised; when the thicker wall portion is located at the upper part of the shaft hole 11, the pendulum shaft 30 sinks. An adjustment slot 21 is provided on the adjustment sleeve 20, extending from one end of the adjustment sleeve 20 to the other, penetrating from the outer wall 201 to the inner wall. By providing the adjustment slot 21, the entire adjustment sleeve 20 can contract under radial force, thereby allowing the adjustment sleeve 20 to tightly grip the pendulum shaft 30. This utility model also includes a locking sleeve 40, which is fitted onto the adjustment sleeve 20 at the position where it extends out of the shaft hole 11, corresponding to the adjustment slot 21. The locking sleeve 40 is provided with a locking member 42 for locking the locking sleeve 40 onto the pendulum shaft 30. By operating the locking member 42, a radial force can be applied to the adjustment sleeve 20, causing the adjustment sleeve 20 and the pendulum shaft 30 to swing together during operation.

[0033] In a preferred embodiment of this invention, the adjusting slit 21 is strip-shaped, specifically elongated, with both ends of the adjusting sleeve 20 extending from the shaft hole 11. The adjusting slit 21 is positioned at the point where the adjusting sleeve 20 extends out of the shaft hole 11. In a preferred embodiment of this invention, there are multiple adjusting slits 21 arranged circumferentially around the adjusting sleeve 20. In a preferred embodiment of this invention, the multiple adjusting slits 21 are divided into two groups, with the two groups distributed at both ends of the adjusting sleeve 20 along its axial direction. In a preferred embodiment of this invention, each group of adjusting slits 21 includes four adjusting slits, which are evenly distributed circumferentially around the adjusting sleeve 20.

[0034] During installation, a plurality of adjusting sleeves 20 and locking sleeves 40 are provided on one of the pendulum shafts 30. The multiple adjusting sleeves 20 ensure the horizontal support of the pendulum shaft 30. In a preferred embodiment of this invention, the adjusting sleeves 20 are provided with indicator scales 22, which are arranged circumferentially around the adjusting sleeves 20. A reference mark is provided on the bracket 10. By observing the relative position of the indicator scales 22 and the reference mark, the rotation angle of the adjusting sleeves 20 can be determined, ensuring that the rotation angles of all adjusting sleeves 20 are the same, thus guaranteeing the horizontality of the pendulum shaft 30.

[0035] In a preferred embodiment of this invention, the locking element 42 is a bolt or screw; in this embodiment, it is a bolt. In another preferred embodiment, the locking sleeve 40 has an adjustment notch 41 extending from the inner wall to the outer wall of the locking sleeve 40. Bolts are inserted at both ends of the locking sleeve 40 corresponding to the adjustment notch 41. By tightening the bolts, the adjustment notch 41 can be enlarged or reduced, thereby tightening or loosening the locking sleeve 40.

[0036] The scope of protection of this utility model is not limited to this embodiment. Any similar modifications made to it are considered to be within the scope of protection of this utility model.
