Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

Example 1:

as shown in fig. 1, the utility model discloses a lifting yarn guide frame for a circular knitting machine, which comprises a mounting frame 1, wherein the mounting frame 1 is used for being mounted on a frame of the circular knitting machine, a guide groove in the vertical direction is arranged on the mounting frame 1, the section of the guide groove is annular, a strip-shaped lifting plate 2 is arranged in the guide groove, the lifting plate 2 is in sliding connection in the guide groove, a long hole 3 is arranged in the lifting plate 2, a screw rod 4 is fixed in the long hole 3, a rotating nut 5 is sleeved on the screw rod 4, a limiting hole is arranged on the mounting frame 1, the rotating nut 5 is clamped in the limiting hole, the rotating nut 5 is in rotary connection in the limiting hole, and a yarn guide hole 6 is arranged at the top of the lifting plate 2.

The lifting plate 2 preferably adopts a strip-shaped thin plate structure, the guide groove penetrates through the mounting frame 1, the outer surface of the lifting plate 2 is attached to the inner surface of the guide groove, and the lifting plate and the guide groove are in relative sliding connection. The long hole 3 sets up along the length direction of lifter plate 2, and lead screw 4 sets up in the long hole 3, and the diameter of lead screw 4 can be less than the thickness of lifter plate 2, and the diameter of rotation nut 5 should be greater than the thickness of mounting bracket 1, and when rotation nut 5 is located spacing downthehole promptly, local rotation nut 5 needs to expose in the outside of mounting bracket 1, and operating personnel can touch rotation nut 5. Wherein the width of the limiting aperture should be equal to or slightly greater than the thickness of the swivel nut 5. When the position of the yarn guide hole 6 on the lifting plate 2 needs to be adjusted, only the rotating nut 5 needs to be rotated clockwise or anticlockwise, and because the lifting plate 2 and the screw rod 4 are fixed together, the screw rod 4 cannot rotate along with the rotation of the rotating nut 5, the rotating nut 5 rotates under the condition that the rotating nut 5 is matched with the screw rod 4, and the screw rod 4 drives the lifting plate 2 to lift. When the nut stops rotating, the heights of the screw rod 4 and the lifting plate 2 can be limited.

The guide groove is annular, namely a hollow structure with a closed section, and the lifting plate 2 can pass through the guide groove.

The position of the yarn passing through the yarn guide hole 6 can be effectively changed through the adjustment, so that the angle of the yarn entering the knitting needle is changed, and the applicability of different yarns is improved.

The yarn guide tube 7 is arranged in the yarn guide hole 6, two connecting rods 8 are arranged in the middle of the yarn guide tube 7, and the connecting rods 8 are rotationally connected with the inner wall of the yarn guide hole 6. The yarn is guided by the yarn guide tube 7, and the direction of the yarn guide tube 7 can be changed under the action of the self weight and tension of the yarn, so that the stability and the reliability of yarn conveying can be realized.

An annular bulge 9 is arranged in the middle of the inside of the yarn guide tube 7, a through hole 10 is formed in the annular bulge 9, and the annular bulge 9 at the through hole 10 is in an arc surface structure.

The annular bulge 9 is arranged in the yarn guide tube 7, so that yarn is contacted with the annular bulge 9 in the conveying process and simultaneously contacted with two ends of the yarn guide tube 7, the contact area between the yarn and the yarn guide tube 7 can be effectively reduced, and the abrasion is reduced. And simultaneously, the angle adjustment and the limitation of the yarn guide tube 7 can be more convenient.
