Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1 to 4, a circular knitting machine ring frame for facilitating yarn replacement includes an upper ring frame 1 and a lower ring frame 2. A plurality of fixing rods 3 are arranged on the upper annular frame 1, and the upper annular frame 1 and the lower annular frame 2 are fixedly connected through the fixing rods 3.

The side wall of the lower annular frame 2 is fixedly provided with a plurality of fixing devices, and each fixing device comprises a connecting column 4, a protective column 5 and a plurality of supporting columns 6. One end of the connecting column 4 is fixedly connected with the lower annular frame 2, the upper end of the connecting column 4 is fixedly provided with the stand column 7, the side wall of the stand column 7 is symmetrically and fixedly provided with two rotary drums 8, the rotary drums 8 are sleeved with the yarn roll, and the rotary drums 8 can support the yarn roll. The one end that stand 7 was kept away from to rotary drum 8 is equipped with separation blade 9, and one side of separation blade 9 sets firmly bolt 10, and the one end of rotary drum 8 is equipped with the slot, inserts bolt 10 in the slot, and separation blade 9 supports in one side of yarn book, and it is fixed with the yarn book, makes the yarn book can not separate with rotary drum 8.

Three mounting holes are formed in the protective column 5 and the connecting column 4, a connecting groove is formed in the middle of the supporting column 6, a bearing 13 is sleeved on the connecting groove, and the outer edge of the bearing 13 is fixedly connected with the side wall of the mounting hole. The supporting column 6 on the connecting column 4 can be propped against the lower part of the yarn coil to generate a supporting force for the yarn coil, so that the yarn coil is not easy to shake.

One end of the connecting column 4, which is far away from the lower annular frame 2, is hinged with the protective column 5, a guide groove is arranged on the connecting column 4, and a tension spring 12 is arranged in the guide groove. The tension spring 12 can generate a tension force on the protective column 5, so that the protective column 5 can drive the supporting columns 6 to move, the three supporting columns 6 on the protective column 5 can be abutted against the side wall of the yarn roll, and the yarn roll can be more stable when rotating. When the diameter of the yarn roll is reduced due to the fact that the yarn on the yarn roll is reduced, the tension spring 12 can pull the protection column 5, the support column 6 on the protection column 5 can be attached to the surface of the yarn roll continuously, one side of the yarn roll is supported, and the yarn roll cannot shake.

The one end of rotary drum 8 sets firmly the slider 11 of T shape, and one side of slider 11 is cylindrically, and one side of slider 11 is pegged graft on rotary drum 8, and rotates with rotary drum 8 and is connected. When the yarn coil rotates, the yarn coil can be driven to rotate together, so that the yarn coil can normally complete yarn feeding work.

Two vertical sliding grooves are symmetrically formed in the upright post 7, and the sliding block 11 is located in each sliding groove and is in sliding fit with each sliding groove. When the diameter of yarn book reduces, rotary drum 8 can drive yarn book downstream under the effect of gravity, makes support column 6 on spliced pole 4 can support the lower extreme at yarn book all the time, makes yarn book more stable.

The support column 6 is sleeved with an anti-slip sleeve 17, the anti-slip sleeve 17 is elastic, and the surface of the anti-slip sleeve 17 is rough. The anti-slip sleeve 17 can generate resistance to the yarn, so that the yarn on the yarn coil can be tensioned when being pulled out, and the processing of the yarn is facilitated.

The lower extreme of spliced pole 4 sets firmly mounting bracket 14, sets firmly a plurality of fixed blocks 15 on the mounting bracket 14, and the lower extreme of fixed block 15 is equipped with godet wheel 16, and godet wheel 16 rotates with fixed block 15 to be connected. The yarn on the yarn roll passes through the godet wheel 16, and the godet wheel 16 guides the yarn, so that the yarn can move to a processing part of the large circular machine, and the processing of the yarn is facilitated.
