[0026] As Figures 1-3 shown, the structure of the yarn feeding frame in the utility model is similar to the existing yarn feeding frame structure, such as the patent disclosed in a kind of braiding machine's yarn feeding frame with publication number CN218145006U, the main improvement point of the utility model is that yarn is conveniently sleeved on yarn feeding frame, improve the efficiency of winding on;When the utility model needs to install yarn roll on yarn feeding frame, start motor 62 to work, motor 62 drives winding rod 63 to rotate, winding rod 63 is supported by support block 61, winding rod 63 pays off wire to first pull rope 64, a plurality of support bars 8 on the outer wall of first pull rope 64 slide down by their own gravity, the both ends of support bar 8 slide with the inner wall of first sliding groove 11, first sliding groove 11 limits support bar 8, so that it will not produce rotation, until a plurality of support bars 8 are gathered below middle frame 3, at this time, a plurality of yarn rolls can be sleeved on the outermost layer of a plurality of yarn drum supporting rods 9, after the outermost layer of a plurality of yarn drum supporting rods 9 is sleeved with yarn roll, start motor 62 to reverse, make first pull rope 64 pull the outermost support bar 8, drive the sleeved yarn roll to rise, when the outermost support bar 8 and the adjacent support bar 8 between the lower layer are straightened by first pull rope 64, it can stop rising, and the yarn roll is sleeved on the next layer of yarn drum supporting rod 9, and so on, until all the yarn drum supporting rods 9 are sleeved with yarn roll, without using lifting tool, improve the efficiency of yarn installation, and increase safety;Wire sleeve is installed on wire guide plate 5, the wire of yarn roll on yarn drum supporting rod 9 passes through wire sleeve to wire.

[0027] The motor 62 in the above can be purchased in the market, which belongs to a mature technology and has been fully disclosed, so the description is not repeated here. The motor 62 is provided with a power connection line, and it is electrically connected with the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that can play a control role.

[0028] As shown in Figure 1 The two ends of the side frame 4 are provided with second sliding grooves 12, and the two ends of the wire outlet guide plate 5 are respectively connected with the inner walls of the two second sliding grooves 12. The adjusting unit 6 further includes two groups of second pull ropes 65 fixedly connected with the winding rod 63. The two groups of second pull ropes 65 are respectively arranged in the two side frames 4 and are fixedly connected with the plurality of wire outlet guide plates 5. When the winding rod 63 rotates, the winding rod 63 winds or unwinds the second pull rope 65, thereby driving the plurality of wire outlet guide plates 5 to ascend or descend. The two ends of the wire outlet guide plate 5 slide in the second sliding groove 12, and the second sliding groove 12 limits the wire outlet guide plate 5 from rotating, so that after the single-layer bobbin support rod 9 is sleeved with the yarn roll, the yarn can be directly threaded into the wire sleeve installed on the wire outlet guide plate 5, and then the wire outlet guide plate 5 ascends synchronously after the yarn roll is lifted by the ascending yarn bobbin support rod 9, so that the yarn can be threaded into the wire sleeve at a low position, which is convenient to use.

[0029] As shown in Figure 1 The upper surface of the top frame 2 is provided with a plurality of guide wheels 7, and the second pull rope 65 is slidably connected with the guide wheel 7. When the second pull rope 65 is wound or unwound, it slides with the guide wheel 7, and the guide wheel 7 guides the second pull rope 65 to reduce friction and wear.

[0030] As shown in Figure 1 One end of each of the two groups of second pull ropes 65 is fixedly connected with the outer wall of the winding rod 63. The two groups of second pull ropes 65 distributed in a staggered manner do not interfere with each other during winding, thereby avoiding the phenomenon of entanglement.

[0031] As shown in Figures 1-3 The two ends of the support strip 8 and the two ends of the wire outlet guide plate 5 are fixedly connected with pulleys 10. The pulleys 10 at the two ends of the support strip 8 are respectively slidably connected with the inner walls of the two first sliding grooves 11, and the pulleys 10 at the two ends of the wire outlet guide plate 5 are respectively slidably connected with the inner walls of the two second sliding grooves 12. The pulleys 10 make the support strip 8 and the wire outlet guide plate 5 have smaller friction when moving, thereby facilitating sliding.

[0032] As shown in Figure 4As shown, the guide wheel 7 comprises two inclined rods 71, the two inclined rods 71 are rotationally connected with a rotating wheel 72, the middle part of the rotating wheel 72 is provided with a circular groove 73, the second pull rope 65 is slidingly connected with the inner wall of the circular groove 73; the inclined rods 71 support the rotating wheel 72, the circular groove 73 and the second pull rope 65 are tangent to the sliding part of the top frame 2, the second pull rope 65 slides in the circular groove 73, and the circular groove 73 limits the second pull rope 65 so that it cannot be separated.

[0033] As shown in Figure 1 , 2 , the height of the wire outlet guide plate 5 adjacent to the supporting strip 8 is lower than the height of the supporting strip 8; the supporting strip 8 is staggered with the adjacent wire outlet guide plate 5, so that a space is left between the two adjacent wire outlet guide plates 5 to facilitate the pulling of the yarn on the yarn drum supporting rod 9.

[0034] As shown in Figure 1 , 3 , the lower end of the first pull rope 64 is fixedly connected with the inner bottom surface of the middle frame 3, and the lower end of the second pull rope 65 is fixedly connected with the inner wall bottom surface of the side frame 4; the lower ends of the first pull rope 64 and the second pull rope 65 are fixed, so that the first pull rope 64 and the second pull rope 65 can be tightened by winding of the winding rod 63, thereby improving the stability of the supporting strip 8 and the wire outlet guide plate 5.

[0035] In this embodiment, the steps are as follows: when it is necessary to install yarn rolls on the yarn feeding frame, the motor 62 is started to work, the motor 62 drives the winding rod 63 to rotate, the winding rod 63 is supported by the supporting block 61, the winding rod 63 pays out the first pull rope 64 and the second pull rope 65, the multiple supporting strips 8 on the outer wall of the first pull rope 64 slide downward by their own gravity, and the multiple wire outlet guide plates 5 on the outer wall of the second pull rope 65 slide downward by their own gravity, until the multiple supporting strips 8 and the multiple wire outlet guide plates 5 are gathered below the middle frame 3 and the side frame 4 respectively, at this time, multiple yarn rolls can be respectively sleeved on the multiple yarn drum supporting rods 9 on the uppermost layer, after the multiple yarn drum supporting rods 9 on the uppermost layer are sleeved with the yarn rolls, the yarn on the yarn rolls is threaded to the wire sleeve installed on the wire outlet guide plate 5, the motor 62 is reversed to drive the first pull rope 64 to pull the uppermost supporting strip 8 and the second pull rope 65 to pull the uppermost wire outlet guide plate 5, so as to drive the sleeved yarn roll to ascend, when the first pull rope 64 is straightened between the uppermost supporting strip 8 and the adjacent supporting strip 8 below it, the ascending is stopped, and a yarn roll is sleeved on the next layer of yarn drum supporting rod 9, and so on, until all the yarn drum supporting rods 9 are sleeved with yarn rolls.

[0036] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For the ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
