Description

Technical Field

[0001] The utility model belongs to the technical field of knitting machines, and particularly relates to a bobbin placing rack for a knitting machine. Background Technique

[0002] A knitting machine refers to a mechanical device used to weave yarn into fabric. The working principle of a knitting machine is to bend the yarn into loops and make these loops string together to form fabric. A bobbin placing rack is arranged on the knitting machine to facilitate the placement of bobbins and realize the feeding of textile silk threads.

[0003] After retrieval, a yarn bobbin placing rack is disclosed in the patent document with the patent publication number CN220976062U, which includes a threaded adjusting rod. A fixed disk is arranged above the threaded adjusting rod. A bearing is fixedly embedded in the bottom surface of the fixed disk. The inner ring of the bearing is fixedly connected to the top end of the threaded adjusting rod. An electric push rod is fixedly connected to the top of the fixed disk. First connecting rods located on the left and right sides of the electric push rod are hinged to the top of the fixed disk. The telescopic end of the top of the electric push rod is fixedly connected to a connecting plate. Second connecting rods are hinged to the left and right sides of the bottom of the connecting plate. By using the electric push rod to drive two movable clamping plates to clamp and fix the yarn bobbin, first, when placing the yarn bobbin, there is no need for manual movement, saving labor and facilitating the placement of the yarn bobbin. Second, when the yarn bobbin is unwinding and rotating, the two movable clamping plates are acted on by the electric push rod and can firmly clamp the yarn bobbin to avoid shaking, improving the stability of the yarn bobbin fixation.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. For the existing knitting machine bobbin placing rack, during use, the bobbin is erected and sleeved on the vertical rod, and the driving component is controlled to adjust the outer diameter size of the vertical rod to lock the position of the bobbin. However, it is not convenient to fix the height size of the vertical rod, not convenient to lock the positions of bobbins at different heights, reducing the applicable range and practicality of the existing knitting machine bobbin placing rack.

[0006] 2. For the existing knitting machine bobbin placing rack, during use, the position of the bobbin is limited by the vertical rod, that is, the placement of the bobbin is realized. However, it is not convenient to adjust the inclination angle of the vertical rod, not convenient to adjust the inclination angle of the bobbin according to work needs, reducing the functionality of the existing knitting machine bobbin placing rack.
