Description

Technical Field

[0001] The invention relates to the technical field of circular knitting machines, and in particular to an adjustable transmission mechanism for circular knitting machines. Background Art

[0002] Needle spinning machinery is a common textile machinery equipment. In many knitting enterprises, small-diameter circular knitting machines are commonly used. Small-diameter circular knitting machines are usually divided into two types: ordinary circular knitting machines and jacquard circular knitting machines. The former weaves fabrics with simple organizational structures, while the latter can weave fabrics with multi-color jacquard structures. In the process of fabric weaving, small-diameter circular knitting machines usually use pre-designed jacquard patterns. The colored yarns of the loop forming system are padded from the weft direction onto the selected and elevated knitting needles to form loops, while the other needles that have not been selected are in a low working position waiting for other loop forming systems to select needles to form loops.

[0003] The high-precision fully automatic jacquard circular knitting machine in the prior art, when working, because the weaving of the fabric is carried out in rotation, the fabric is also rotating when it is discharged. At this time, the winding device for receiving the fabric at the bottom of the circular knitting machine also needs to rotate synchronously with the fabric. The existing winding device is generally fixedly connected to the knitting device rotating above through a transmission arm, which can not only rotate synchronously with the fabric, but also provide winding power by providing a gear set at the rotating part of the bottom, using the relative rotation of the winding device and the frame base. Therefore, the transmission arm between the winding device and the knitting device needs to bear a large load. When starting and stopping, the transmission arm is easily damaged due to the huge instantaneous impact load, and there is room for further improvement. Summary of the invention

[0005] To achieve the above-mentioned purpose, an adjustable transmission mechanism for a circular knitting machine is provided, comprising a circular knitting machine base and a middle frame, the top of the circular knitting machine base is fixedly connected to the middle frame, the lower center of the circular knitting machine base is rotatably connected to a rotating seat, the upper part of the rotating seat is fixedly connected to a material receiving frame, both ends of the upper part of the material receiving frame are fixedly connected to connecting frames, the upper part of the material receiving frame is fixedly connected to a regular octagonal frame body through two connecting frames, the upper part of the regular octagonal frame body is fixedly connected to spring shaft seats at the side positions on both sides of the two connecting frames, the upper parts of the four spring shaft seats are fixedly connected to spring slide bars, the middle parts of the four spring slide bars are slidably sleeved with connecting seats, and buffer springs are arranged on both sides of the four connecting seats; The upper parts of the four connecting seats are rotatably connected with adjusting transmission arms, and the lower parts of the inner side of the middle frame are provided with connecting transmission arms at positions corresponding to the four adjusting transmission arms, and the bottoms of the four connecting transmission arms are rotatably connected with the corresponding adjusting transmission arms.

[0006] According to the adjustable transmission mechanism for a circular knitting machine, the adjusting transmission arm includes an adjusting slide, a limiting sleeve, a limiting slide groove and a limiting bolt. The end of the limiting sleeve away from the connecting seat is rotatably connected to the connecting transmission arm, and the end of the adjusting slide away from the connecting seat is slidably connected to the limiting sleeve. A limiting slide groove is provided in the middle of the limiting sleeve, and two limiting bolts are provided at a position corresponding to the limiting slide groove in the middle of one end of the adjusting slide embedded in the limiting sleeve.

[0007] According to the adjustable transmission mechanism for a circular knitting machine, the width of the limiting slide groove corresponds to the outer diameter of the limiting bolt, and the two limiting bolts both pass through the limiting slide groove and are threadedly connected to the adjusting slide plate.

[0008] According to the adjustable transmission mechanism for a circular knitting machine, a knitting device is arranged on the inner side of the middle frame and the knitting device is an existing circular knitting machine on the market, and the tops of the four connecting transmission arms are fixedly connected to the bottom of the knitting device.

[0009] According to the adjustable transmission mechanism for a circular knitting machine, the four spring slide bars all penetrate two corresponding buffer springs and are movably sleeved with the corresponding buffer springs.
