Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for a braiding machine, in particular to a feeding mechanism for a braiding machine. Background Art

[0002] The feeding mechanism of the yarn braiding machine is an important part of the yarn braiding machine. It is mainly responsible for feeding the yarn into the braiding mechanism to ensure that the yarn can be continuously and stably supplied to the braiding process.

[0003] The existing yarn knitting machine feeding mechanism is relatively loose when the yarn is fed due to its elasticity. When the yarn is loose, the tension will decrease, resulting in the yarn being unable to maintain a stable tension state during the feeding process. If the tension is too small, the yarn will deviate due to gravity or external interference before entering the knitting area, and will not be able to accurately enter the predetermined knitting area. Utility Model Content

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0020] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0021] This embodiment mainly describes a feeding mechanism of a knitting machine, which is as follows:

[0022] like Figure 1-4 As shown, a feeding mechanism of a braiding machine comprises a base 1, a fixing plate 2 is fixedly installed on the left side of the upper end of the base 1, a fixing rod 3 is fixedly installed on the upper side of the right end of the fixing plate 2, a fixing cylinder 4 is fixedly installed on the right end of the fixing rod 3, a yarn 5 is movably connected to the outer surface of the fixing cylinder 4, four supporting legs 6 are fixedly installed on the upper end of the base 1, a supporting frame 7 is fixedly installed on the upper ends of the four supporting legs 6, the supporting frame 7 is arranged in a U shape, an adjusting component 8 is arranged on the left side of the upper end of the supporting frame 7, a guide pressure wheel 9 is fixedly installed in the middle of the adjusting component 8, a fixing frame 10 is fixedly installed on the right side of the upper end of the supporting frame 7, and a driving component is arranged on the left end of the fixing frame 10 11. A feed roller 12 is fixedly installed at the right end of the driving assembly 11. The axis lines of the fixed cylinder 4 and the feed roller 12 coincide. The yarn 5 is movably connected to the feed roller 12. The yarn 5 on the fixed cylinder 4 is unwound and wound on the feed roller 12. The guide pressure wheel 9 can apply a certain pressure to the yarn 5 to make it fit more closely on the feed roller 12, reducing the shaking and loosening of the yarn 5 during the transmission process. The guide pressure wheel 9 can ensure that the yarn 5 is transported from the fixed cylinder 4 to the feed roller 12 according to the predetermined path, avoiding the yarn 5 from deviating from the track during the transmission process. The rotating feed roller 12 provides a stable transmission platform for the yarn 5. Compared with feeding directly from the fixed cylinder 4, the rotation of the feed roller 12 can ensure that the yarn 5 maintains continuity and stability during the transmission process, reducing the loosening and winding of the yarn 5.

[0023] The opposite surfaces of the support legs 6 are fixedly mounted with a stabilizing plate 13, which forms a more stable structure by connecting the two support legs 6. This structure can effectively prevent the support legs 6 from shaking or tilting due to uneven force or external force during use, thereby improving the stability of the entire device or structure.

[0024] A guide plate 14 is fixedly installed on the right part of the fixed frame 10, and a guide hole 15 is opened at the right end of the guide plate 14. Usually, a guide plate 14 and a guide hole 15 are provided. The yarn 5 passes through the guide hole 15 to ensure that the yarn 5 moves along a predetermined path during the transmission process, avoids the yarn 5 from deviating from the predetermined trajectory, and enables the yarn 5 to accurately enter the weaving area.

[0025] like Figure 3 As shown, the adjustment component 8 includes a fixed block 81, two fixed blocks 81 are provided, and the opposite surfaces of the two fixed blocks 81 are movably connected with a rotating shaft 82, the front end of the rotating shaft 82 is fixedly installed with a first servo motor 83, and the outer surface of the rotating shaft 82 is fixedly installed with two adjustment plates 84, and the opposite surfaces of the two adjustment plates 84 are fixedly installed with a connecting rod 85, and the guide pressure wheel 9 is fixedly connected to the connecting rod 85. The first servo motor 83 drives the rotating shaft 82 to rotate clockwise, thereby driving the adjusting plate 84 to rotate and drive the guide pressure wheel 9 to apply pressure to the yarn 5.

[0026] like Figure 4 As shown, the driving assembly 11 includes a second servo motor 111, and a driving shaft 112 is fixedly installed at the output end of the second servo motor 111. The driving shaft 112 and the feeding roller 12 are fixedly connected. The second servo motor 111 is fixedly connected to the left end of the fixed frame 10. The driving shaft 112 is driven to rotate by the second servo motor 111, thereby driving the feeding roller 12 to rotate.

[0027] When in use, the yarn 5 on the fixed cylinder 4 is unloaded and wound around the feeding roller 12. The first servo motor 83 drives the rotating shaft 82 to rotate clockwise, thereby driving the adjusting plate 84 to rotate and driving the guide pressure wheel 9 to apply pressure to the yarn 5. The guide pressure wheel 9 can apply a certain pressure to the yarn 5 to make it fit more closely on the feeding roller 12, reducing the shaking and relaxation of the yarn 5 during the transmission process. The guide pressure wheel 9 can ensure that the yarn 5 is transported from the fixed cylinder 4 to the feeding roller 12 along a predetermined path, avoiding the yarn 5 from deviating from the track during the transmission process. The driving shaft 112 is driven to rotate by the second servo motor 111, thereby driving the feeding roller 12 to rotate. The rotating feeding roller 12 provides a stable transmission platform for the yarn 5. Compared with feeding directly from the fixed cylinder 4, the rotational movement of the feeding roller 12 can ensure that the yarn 5 maintains continuity and stability during the transmission process, and reduce the relaxation and entanglement of the yarn 5. A guide plate 14 and a guide hole 15 are usually provided. The yarn 5 passes through the guide hole 15 to ensure that the yarn 5 moves along a predetermined path during the transmission process, avoids the yarn 5 from deviating from the predetermined trajectory, and enables the yarn 5 to accurately enter the weaving area.
