Description

Technical Field

[0001] The utility model belongs to the field of large circular knitting machines, and in particular relates to an adjustable yarn feeding component of a large circular knitting machine. Background Art

[0002] Circular knitting machine, scientifically known as circular weft knitting machine, has developed rapidly due to its multiple loop forming systems, high speed, high output, fast pattern change, good fabric quality, few processes and strong product adaptability.

[0003] The existing yarn feeding assembly is adjusted by opening a number of key slots at intervals in the axial direction of the yarn feeding shaft, and installing the limit disk in a key connection manner. Different key slot positions correspond to different limit disk positions. After the limit disk is installed, the yarn feeding disk is put on the yarn feeding shaft, one end of which is against the limit disk, and the other end is against the yarn feeding shaft through a locking bolt, so that the position of the yarn feeding disk is adjusted. However, this method uses a key connection, and the disassembly and assembly of the limit disk is inconvenient. The limit disk and the yarn feeding disk are separate, and the disassembly and assembly need to be divided into two steps, namely the disassembly and assembly of the limit disk and the disassembly and assembly of the yarn feeding disk. The disassembly and assembly time is long, resulting in a long time for adjusting the position of the yarn feeding disk. Utility Model Content

[0031] like Figures 1 to 6As shown, the adjustable yarn feeding assembly of the large circular knitting machine provided in this embodiment includes a yarn feeding shaft 1, a yarn feeding disk 2, a fixing sleeve 3, a bolt 4, a convex strip 5, a spring 6, and a clamping bead 7. The outer wall of the yarn feeding shaft 1 is provided with a slide groove 8 running through the upper and lower ends thereof, the inner wall of the yarn feeding disk 2 is fixed with a convex strip 5, the convex strip 5 is slidably matched with the slide groove 8, the yarn feeding shaft 1 is provided with a plurality of clamping grooves 9 at intervals along its axial direction, the clamping groove 9 is connected with the slide groove 8, a receiving groove 10 is provided inside the convex strip 5, a spring 6 is fixed in the receiving groove 10, a clamping bead 7 is fixed at the inner end of the spring 6, the clamping bead 7 is slidably matched with the receiving groove 10, and the clamping groove 9 is clamped with the clamping bead 7, a fixing sleeve 3 is fixed on the top of the yarn feeding disk 2, the fixing sleeve 3 is sleeved on the yarn feeding shaft 1, a through hole 11 is provided on the side wall of the fixing sleeve 3, a plurality of threaded holes 12 are provided on the outer wall of the yarn feeding shaft 1, the bolt 4 passes through the through hole 11 and is screwed with the threaded hole 12. The cooperation of the convex strip 5 and the slide groove 8 plays a role in positioning and guiding. The through slide groove 8 is set, and there is no obstruction when adjusting the position of the yarn feeding disc 2, and the yarn feeding disc 2 does not need to be removed from the yarn feeding shaft 1 during adjustment. The position of the yarn feeding disc 2 is fixed by the cooperation of the spring 6, the card bead 7, and the card slot 9. When adjusting, it is only necessary to loosen the bolt 4 until it leaves the threaded hole 12, and then push the fixing sleeve 3 up and down to make the yarn feeding disc 2 move up and down, the spring 6 contracts, and the card bead 7 retracts into the accommodating groove 10 until the card bead 7 moves to the next card slot 9. The spring 6 extends, driving the card bead 7 to be stuck in the card slot 9, completing the fixation of the yarn feeding disc 2, and finally tightening the bolt 4 for reinforcement. In this way, the adjustment of the position of the yarn feeding disc 2 only requires screwing the bolt 4, and then pushing the fixing sleeve 3 up and down with force. The operation is simple and the adjustment time of the position of the yarn feeding disc 2 is short. There is no need to set an additional limit plate, so there is no need to disassemble and assemble the limit plate and the yarn feeding disc 2 in steps. The fixing is performed by a combination of a clamping connection and a screw connection, thereby improving the stability of the yarn feeding disc 2 after the position is adjusted.

[0032] There are two groups of card slots 9, which are symmetrically arranged along the axis of the yarn feeding shaft 1, and two card beads 7 are symmetrically arranged along the axis of the yarn feeding disc 2. The two groups of card slots 9 of this embodiment are respectively arranged on the front and rear sides of the yarn feeding shaft 1, and the two card beads 7 are respectively arranged on the front and rear sides of the yarn feeding disc 2. The two groups of card slots 9 arranged symmetrically are combined with the two card beads 7 arranged symmetrically to improve the installation stability.

[0033] Each group of slots 9 includes a plurality of slots 9 equidistantly arranged along the axial direction of the yarn feeding shaft 1. The slots 9 equidistantly arranged can achieve precise adjustment of the position of the yarn feeding disc 2. In this embodiment, each group of slots 9 includes four slots 9, and each group of threaded holes includes four threaded holes, that is, four adjustment positions. Precise fixed adjustment is achieved by the cooperation of the card beads 7 and the slots 9 at the corresponding positions.

[0034] The threaded holes 12 are staggered with the slots 9 in the vertical direction and staggered with the slots in the circumferential direction. There are two groups of threaded holes 12, and the two groups of threaded holes 12 are symmetrically arranged along the axis of the yarn feeding shaft. The vertical line between the threaded holes 12 and the yarn feeding shaft 1 and the vertical line between the slots 9 and the yarn feeding shaft 1 are arranged perpendicular to each other. In this way, the yarn feeding disc 2 is fixed from four directions, front, back, left, and right, to ensure the stability of the yarn feeding disc 2 after the position is adjusted.

[0035] The through hole 11 is a countersunk hole, and the arrangement of the countersunk hole allows the bolt 4 to be built into the countersunk hole, thereby preventing the bolt 4 from being exposed.

[0036] The outer side wall of the fixing sleeve 3 is provided with anti-skid patterns 13. The anti-skid patterns 13 have an anti-skid effect and are more conducive to pushing the fixing sleeve 3.
