[0031] like Figures 1 to 6 As shown, an adjustable knitting circular knitting machine wire guide device provided in this embodiment includes a guide rail 1, a slider 2, a first spring 3, a first clamping bead 4, a front-rear position adjusting member 5, and a wire guide seat 6. The guide rail 1 is slidably connected with a plurality of sliders 2. A first receiving groove 7 is provided above the inside of the slider 2. A first spring 3 is fixed to the top wall of the first receiving groove 7. A first clamping bead 4 is fixed to the bottom end of the first spring 3. The first clamping bead 4 is slidably matched with the first receiving groove 7. A plurality of first clamping grooves 8 are equidistantly provided at the top of the guide rail 1 along its length direction. The first clamping bead 4 is clamped with the first clamping groove 8. The number of the first clamping grooves 8 is at least twice the number of the first clamping bead 4. A front-rear position adjusting member 5 is fixed to the top of the guide rail 1. The rear end of the front-rear position adjusting member 5 is detachably connected with the wire guide seat 6. A wire guide hole 9 is provided in the middle of the wire guide seat 6. When adjusting the position of the wire guide seat 6, it is only necessary to push the slider 2 left and right. When the slider 2 is pushed, the first clamping bead 4 retracts into the first receiving groove 7, and the first spring 3 contracts until the first clamping bead 4 moves to the next first clamping groove 8, and the first spring 3 extends, pushing the first clamping bead 4 into the first clamping groove 8 to complete the fixation. In this way, only a simple structure is needed to conveniently adjust the guide wire position to the left and right. The adjustment only requires pushing the slider 2 to the left and right, and the adjustment takes a short time. In addition, the first clamping grooves 8 arranged at equal intervals can intuitively judge the distance between adjacent guide wire positions after adjustment.

[0032] The number of first slots 8 is set to ensure the adjustability of the position of the slider 2. The front and rear position adjusting members can adjust the front and rear guide wire positions. The guide wire seat 6 is detachably connected to the front and rear position adjusting members, and the guide wire seat 6 can be replaced according to the use requirements, or the guide wire seat 6 can be removed for cleaning.

[0033] Among them, the front and rear position adjustment member 5 includes a cross arm 51, a second clamping bead 52, a second spring 53, and an adjustment rod 54. The cross arm 51 is fixed to the bottom of the guide rail 1. A slot 55 is provided inside the cross arm 51. The adjustment rod 54 is inserted into the slot 55 and slides with the slot 55. The upper and lower sides of the front end of the adjustment rod 54 are provided with second receiving grooves 56. The inner side wall of the second receiving groove 56 is fixed with a second spring 53. The outer end of the second spring 53 is fixed with a second clamping bead 52. The second clamping bead 52 slides with the second receiving groove 56. The cross arms 51 on the upper and lower sides of the slot 55 are provided with a plurality of second clamping grooves 57. The plurality of second clamping grooves 57 are equidistantly spaced along the length direction of the cross arm 51. The second clamping bead 52 is engaged with the second clamping groove 57. The second clamping grooves 57 opposite to each other on the upper and lower sides are grouped as a group and are engaged with the second clamping beads 52 on the upper and lower sides of the adjustment rod 54. When the guide wire position needs to be adjusted forward and backward, it is only necessary to push the adjustment rod 54 forward and backward. When the adjustment rod 54 is pushed, the second clamping bead 52 retracts into the second receiving groove 56, and the second spring 53 contracts until the second clamping bead 52 moves to the next second clamping groove 57, and the second spring 53 extends to push the second clamping bead 52 into the second clamping groove 57 to complete the fixation. In this way, only a simple structure is needed to conveniently realize the front and rear adjustment of the guide wire position, and the adjustment only needs to push the adjustment rod 54 back and forth, and the adjustment takes a short time.

[0034] Among them, the outer side wall of the adjustment rod 54 is provided with a plurality of scale lines 58, and the plurality of scale lines 58 are equidistantly spaced along the length direction of the adjustment rod 54. The spacing between adjacent scale lines 58 is consistent with the spacing between adjacent second card slots 57. Through the setting of the scale lines 58, the front and rear adjustment distance of the guide wire position can be intuitively judged. Specifically, it is judged by the number of scale lines 58 exposed outside the cross arm 51. For example, when the number of scale lines 58 exposed outside the cross arm 51 is one, it corresponds to the second card bead 52 being stuck in the second card slot 57 at the front end, and when the number of scale lines 58 exposed outside the cross arm 51 is two, it corresponds to the second card bead 52 being stuck in the second group of second card slots 57 from the front to the back, and so on. Ensure the precise adjustment of each guide wire position.

[0035] Among them, the rear end of the adjustment rod 54 is provided with a third card slot 10, and the front end of the guide wire seat 6 is fixed with a card block 11 engaged with the third card slot 10. Through the cooperation of the card block 11 and the third card slot 10, the guide wire seat 6 can be quickly disassembled and assembled in a card-fitting manner.

[0036] There are eight third card slots 10, which are equally spaced around the center line of the adjustment rod 54. The eight third card slots 10 are divided into four groups, each of which includes two third card slots 10 symmetrically arranged along the center line of the adjustment rod 54. A group of card blocks 11 capable of engaging with each group of third card slots 10 is fixed to the front end of the guide wire seat 6, and a group of card blocks 11 includes two card blocks 11 symmetrically arranged along the center line of the guide wire seat 6. The four groups of third card slots 10 correspond to the four orientations of the guide wire seat 6, so as to adjust the angle of the guide wire seat 6 to meet different usage requirements.

[0037] The inner wall of the wire guide hole 9 is provided with a soft brush 12. The provision of the soft brush 12 can effectively prevent dust on the silk thread from being woven into the knitted fabric, thereby improving the knitting quality of the knitted fabric.
