Description

Knitting circular machine sinker triangular adjustment tool and adjustment method

Technical Field

The invention relates to tooling equipment and a using method thereof, in particular to a sinker triangular adjustment tooling and an adjustment method of a circular knitting machine.

Background

The circular knitting machine has a circular knitting machine equipped with a circular needle bed having a vertical needle path on which latch needles or compound needles can move and a circular stocking machine.

In addition to the needles, another special element called a "sinker" acts perpendicularly to the needles during the looping cycle.

The sinker serves two main functions: pulling down the already formed fabric when the needles are raised to knit a new course; supporting the fabric as the previous courses are knocked over.

The sinker has a particular shape, with two main parts: nose (upper part) and chest (lower part) can move back and forth in the horizontal direction under special triangle drive.

The sinker in the circular knitting machine moves through the track on the sinker triangle to form a loop in a matching way, so as to achieve the fabric meeting the requirements.

The relative positions of the cams of each sinker and the needle cylinder are important, and if the angles are uneven, the positions are different, so that the quality of the fabric is reduced, and the quality of the cloth is affected.

At present, the triangle of the sinker is basically adjusted by adopting a surface beating method, and a plurality of sinkers are arranged in the upper ring of the needle cylinder. The dial indicator is arranged on the needle cylinder, and the dial indicator head is arranged on the head of the sinker. The machine was slowly rocked and the dial head was observed, the maximum reading was seen and noted (recall that the set to the specified size value was first made). Continuing to shake slowly, looking at the maximum reading value of the next path, and comparing with the previous value, and adjusting to the requirement if the maximum reading value is different. And after the whole circle of adjustment is finished, the machine is further hit, and if the difference exists, the adjustment is performed again until the machine meets the requirements.

It has the following disadvantages:

1. the high points are not found well (the triangle track is a curve, and the high points only have one point), so that the reading is affected;

2. the operation is troublesome, and the time and the labor are wasted for adjusting the machine;

3. because the sinker cams are matched with the top-quality upper disc with a little clearance, the adjustment can influence the uniform distribution condition of each sinker cam.

In view of this, the present invention has been made.
