The second fixing screw 5 fixes the sinker triangle 2 on the fixed ring 1 when tightened; and when the second fixing screw 5 is rotated and tightened, it drives the sinker triangle 2 to move in the radial direction of the fixed ring 1 to fine-tune the position of the sinker triangle 2 in the radial direction of the fixed ring 1, so that the end face of the first fixing screw 4 is against the inner wall of the protruding retaining ring 11 of the fixed ring 1, so that the central axis of the sinker triangle 2 coincides with the central axis of the fixed ring 1 and the syringe 110, so that the central axis of the circular ring formed by the multiple sinker triangles 2 coincides with the central axis of the fixed ring 1 and the central axis of the syringe 110. The sinker 130 is arranged on the sinker triangle 2.

[0050] It is not difficult to find from the above content that the sinker triangle installation structure of the circular knitting machine of the present embodiment is provided with a fixing ring, a sinker triangle, an adjusting gasket, a first fixing screw and a second fixing screw. The fixing ring is provided with a protruding retaining ring, the sinker triangle is provided with a threaded hole, the first fixing screw is engaged with the threaded hole, a plurality of adjusting gaskets are sleeved on the first fixing screw, a plurality of sinker triangles are arranged in a circular ring shape on the fixing ring, the second fixing screw is passed through the first fixing hole of the sinker triangle to fix the sinker triangle on the fixing ring, and the second fixing screw is used to make the first fixing screw and the protruding retaining ring abut against each other when tightened. The sinker cam installation structure of the large circular knitting machine of the present embodiment, when installing and assembling the sinker cam, first use the first sinker cam as a reference by using adjusting gaskets of different thicknesses, rotate the second fixing screw, and drive the sinker cam to move in the radial direction of the fixing ring, so that the end face of the first fixing screw is in contact with and abuts against the protruding retaining ring of the fixing ring; then the remaining sinker cams can be directly installed on the fixing ring using the number of adjusting gaskets used by the reference block, and the first fixing screw is in contact with and abuts against the protruding retaining ring of the fixing ring, so that the central axis of the circular ring formed by the sinker cam is coincident with the central axis of the needle cylinder and the fixing ring, without the need for repeated measurement operations, saving assembly time and improving work efficiency; when cleaning the yarn fluff in the needle cylinder sinker area during daily maintenance, the sinker cams can be removed one by one for cleaning, and after cleaning, they can be installed in the same way, which is convenient and quick.

[0051] Optional, such as Figure 4 , Figure 6 As shown, in the sinker cam installation structure of the circular knitting machine in this embodiment, the top end of the first fixing hole 21 of the sinker cam 2 is in an outwardly expanding cone shape.

[0052] The second fixing screw 5 includes a cylindrical section 51 and a conical head 52 .

[0053] The outer diameter of the cylindrical section 51 of the second fixing screw 5 is smaller than the aperture of the first fixing hole 21 of the sinker triangle 2, and the conical head 52 is eccentrically arranged at the top of the cylindrical section 51, that is, the central axis of the conical head 52 is offset from the central axis of the cylindrical section 51 by a certain distance.

The conical head of the second fixing screw abuts against the conical section at the top of the first fixing hole. When the second fixing screw is rotated and tightened, the conical head pushes the sinker triangle to move outward in the radial direction of the fixing ring, so that the end face of the first fixing screw contacts and abuts against the inner side face of the protruding retaining ring, so that the central axis of the sinker triangle coincides with the central axis of the fixing ring.

[0055] Furthermore, the sinker cam mounting structure of the circular knitting machine in this embodiment further includes: a locking screw 61 and a locking washer 62.

[0056] The sinker triangle 2 is provided with a second fixing hole 22 . The second fixing hole 22 is a step-shaped elongated hole. The elongated hole is arranged along the mirror image of the fixing ring 1 .

When the first fixing screw 4 abuts against the inner wall of the protruding retaining ring 11, the arc end face of the first fixing screw 4 is in complete contact with the arc inner wall of the protruding retaining ring 11, ensuring that the central axis of the sinker triangle 2 coincides with the central axis of the fixing ring 1 and the needle cylinder 110.

[0061] Optionally, in the sinker cam installation structure of the circular knitting machine in this embodiment, the sinker cam 2 is provided with a limiting protrusion 23 and a limiting groove 24 on the opposite side walls.

[0063] Optionally, in the sinker triangle mounting structure of the circular knitting machine in this embodiment, the adjusting gasket 3 has a variety of different thickness specifications, such as adjusting gaskets 3 with thicknesses of 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, and 1.0 mm.

[0064] If the diameter of the needle cylinder of the circular knitting machine is different, the distance between the needle cylinder and the fixed ring will change. By adjusting the number and specifications of the adjusting gaskets, the sinker cam can be installed on the circular knitting machine with different needle cylinder diameters, which facilitates the installation and use of the sinker cam 2 on the circular knitting machine with different needle cylinder diameters.

[0065] Furthermore, in the sinker triangle installation structure of the circular knitting machine in this embodiment, a limiting pin 12 is provided on the top surface of the fixing ring 1.

[0066] A limiting hole 25 is provided on the bottom surface of the sinker triangle 2 , and the diameter of the limiting hole 25 is slightly larger than the outer diameter of the limiting pin 12 .

[0067] When installing the sinker triangle 2, the limiting pin 12 of the fixing ring 1 is inserted into the limiting hole 25 of the sinker triangle 2, so that the sinker triangle is quickly positioned on the fixing ring, and then the sinker triangle is positioned and locked by the second fixing screw and the locking screw.
