Description

Technical Field

[0001] This utility model belongs to the technical field of knitting equipment, and more specifically, it relates to a yarn feeding frame for a circular knitting machine. Background Technology

[0002] The circular knitting machine, also known as a circular weft knitting machine (or circular weft knitting machine), has developed rapidly due to its numerous loop-forming systems (referred to as the number of yarn feed paths or loop-forming paths in enterprises, or simply paths), high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability. In knitting production, the yarn feeder is indispensable. Its main function is to provide yarn to the circular knitting machine and ensure its normal spinning production. The yarn feeder is divided into two rows and stands vertically on both sides of the machine in a straight or circular shape. The yarn bobbins are inserted into the bobbin frame of the yarn feeder.

[0003] Based on the above, the inventors have discovered the following problems: Existing yarn feeding frames occupy a large area and cannot be moved, the overall height is not easy to adjust, and the spacing between yarns is mostly fixed, which results in wasted space when the yarn bobbin is small.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a yarn feeding frame for a circular knitting machine in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and function of the yarn feeding frame of this utility model for a circular knitting machine are achieved by the following specific technical means: A yarn feeding frame for a circular knitting machine includes a base frame. A sleeve is installed on the top of the base frame, and a main sleeve is inserted into the sleeve. A main support rod is installed on the main sleeve via an adjustment component, and a counterweight rod is installed on the top of the main support rod. A long rod is installed around the side wall of the main support rod, and a short rod is inserted into the end of each long rod. The side walls of both the long and short rods have mounting grooves, and a yarn feeding rod is installed in the mounting grooves.

[0006] Furthermore, the mounting groove is provided with a limiting groove and a sliding groove respectively. A circular block is installed at the end of the yarn feeding rod. Limiting blocks are symmetrically installed on the side wall of the circular block. Positioning blocks are provided on the side wall of the limiting blocks. Positioning holes are provided at equal intervals on the side wall of the limiting groove. The circular block is assembled and installed with the limiting groove through the limiting blocks and positioning blocks. A circular groove is opened on the back of the circular block. A spring is installed on the circular block through the circular groove and the fixing component. The size of the spring is adapted to the sliding groove.

[0007] Furthermore, the adjustment assembly includes a chamber formed on the side wall of the main support rod and a through hole formed on the side wall of the main sleeve. A protrusion is slidably installed between the inner walls of the chamber. A spring is installed on one side of the protrusion inside the chamber, and the diameter of the protrusion is adapted to the size of the through hole.

[0008] Furthermore, the inner wall of the sleeve is provided with equidistant positioning grooves, and the outer wall of one end of the main sleeve is provided with equidistant positioning strips. The sleeve is assembled and installed with the positioning strips provided on the side wall of the main sleeve through the positioning grooves. Compared with the prior art, the present invention has the following beneficial effects: Using the limiting block, positioning block, spring one, and positioning holes on the side wall of the limiting groove, when it is necessary to adjust the position of the yarn feeding rod in the mounting groove, first press spring one into the sliding groove, then insert the circular block into the mounting groove, prioritizing ensuring that the limiting block is horizontal. After inserting to a certain depth, rotate the circular block to rotate the limiting block into the limiting groove, and release the pressing force on the circular block. At this time, the positioning block on the side wall of the limiting block will match the positioning hole in the limiting groove, thereby completing the fixation. Through the above operation, the position of the yarn feeding rod can be changed at will, so that different numbers of yarn feeding rods can be installed on the yarn feeding frame. The design of the positioning groove and positioning strip allows the main sleeve to be rotated freely when it is pulled up, making this type of yarn feeding frame suitable for use at different angles and greatly improving convenience. The height of the main sleeve and the main support rod can be adjusted by using the protrusion block, spring 2 and through hole, so that the height of this type of spinning frame can be freely adjusted.
