Description

Technical Field

[0001] The invention relates to the field of knitting equipment, more specifically, to a core upper disc of a double-sided circular knitting machine. Background Art

[0002] Circular knitting machine, scientifically known as circular weft knitting machine (or circular weft knitting machine), has developed rapidly due to its multiple loop forming systems (called yarn feeding paths or loop forming paths in enterprises, referred to as paths), high speed, high output, fast shape change, good fabric quality, few processes and strong product adaptability.

[0003] When the circular knitting machine cooperates with the yarn guide to supply yarn, the yarn guide cannot automatically detect the yarn knots on the yarn surface, which can easily lead to quality degradation, failure or thread breakage of the finished product.

[0004] Therefore, there is an urgent need for a double-sided circular knitting machine core upper disc that can effectively remove yarn knots on the yarn surface. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a double-sided circular knitting machine core upper disc to solve the defect that when the large circular knitting machine in the prior art cooperates with a yarn guide to supply yarn, the yarn guide cannot automatically detect the yarn knots on the yarn surface, which easily leads to the quality reduction, failure or breakage of the finished product.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] A double-sided knitting circular machine core upper plate, whose structure includes an upper plate base, a needle cylinder body arranged on the upper surface of the upper plate base, an air cavity ring located on the upper surface of the needle cylinder body, a storage frame horizontally mounted on the upper surface of the air cavity ring and a yarn guide connected to the air cavity ring, the yarn guide includes a mounting seat, a yarn guide plate arranged on the upper surface of the mounting seat, a roller arranged on the side of the mounting seat, a yarn smoothing structure located below the roller and connected to the side of the mounting seat, a transfer frame located on the surface of the yarn smoothing structure and matched therewith, and a branch pipe used to connect the transfer frame with the air cavity ring, the yarn smoothing structure includes a threading post with a double-ring structure and a hollow structure inside, a mesh plate arranged on the adjacent surface of the threading post and the transfer frame, and a smoothing plate arranged on the inner ring surface of the threading post.

[0008] As a further solution of the present invention, the inner ring surface of the threading post is provided with a plurality of holes.

[0009] As a further solution of the present invention, an adhesive layer is laid in the inner cavity of the threading column to achieve adsorption and fixation of the yarn knot.

[0010] As a further solution of the present invention, the scraping plate is installed in a staggered manner at the inner ring position of the threading column, and its end surface is provided with a soft serration structure for scraping off the yarn knots on the surface of the yarn.

[0011] As a further solution of the present invention, a suction pump is provided inside the storage frame for collecting the yarn knot impurities after being cleared in cooperation with the yarn guide.

[0012] Advantageous Effects of the Invention

[0013] Compared with the traditional double-sided circular knitting machine core upper disc, the present invention has the following beneficial effects:

[0014] When the yarn passes through the yarn guide plate, contacts the roller and passes through the threading column, the yarn knots on the surface of the yarn can be removed under the contact of the stroke plate arranged inside the threading column and the high-speed operation of the yarn. The removed yarn knots pass through the holes arranged at the inner ring position of the threading column and enter the interior of the threading column. Under the action of the suction force of the storage frame, these yarn knots are collected in the storage frame.

[0015] The present invention makes further improvements to the yarn guide, so as to realize the removal of yarn knots on the surface of the yarn, and to collect the removed yarn knots in a centralized manner, thereby improving the quality of the knitted finished product.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 4 As shown, the present invention provides a technical solution for the heart upper plate of a double-sided circular knitting machine:

[0025] As shown in the figure, a double-sided circular knitting machine core upper plate, the structure of which includes an upper plate base 1, a needle cylinder body 2 arranged on the upper surface of the upper plate base 1, an air cavity ring 3 located on the upper surface of the needle cylinder body 2, a storage frame 4 horizontally mounted on the upper surface of the air cavity ring 3 and a yarn guide 5 connected to the air cavity ring 3, the yarn guide 5 includes a mounting seat 51, a yarn guide plate 52 arranged on the upper surface of the mounting seat 51, and a roller 53 arranged on the side of the mounting seat 51. , a yarn-winding structure 54 located below the roller 53 and connected to the side of the mounting seat 51, a transfer frame 55 located on the surface of the yarn-winding structure 54 and cooperating therewith, and a branch pipe 56 for connecting the transfer frame 55 with the air cavity ring 3. The yarn-winding structure 54 includes a threading column 541 with a double-ring structure and a hollow structure inside, a mesh plate 542 arranged on the adjacent surface of the threading column 541 and the transfer frame 55, and a winding plate 543 arranged on the inner ring surface of the threading column 541.
