Improved structure of ceramic yarn feeding wheel

The present invention relates to an improved structure of a ceramic yarn feeding wheel, and more particularly to a ceramic member for providing a yarn winding, wherein the upper end yarn guiding portion, the intermediate yarn guiding portion and the lower end yarn guiding portion are integrally sintered, not only It is easy to manufacture, the manufacturing precision and quality are easy to control, and the tension in the middle of the ceramic part is enhanced to withstand the stress, so that the middle part of the ceramic part can be effectively supported in the middle of the yarn feeding process, and the yarn guiding portion and the intermediate guide are inserted into the upper end of the ceramic piece. The yarn portion is set such that the diameter of the upper end portion is larger than the diameter of the lower end portion, and the yarns wound around the periphery of all the ceramic parts can be automatically moved down in order to achieve the purpose of smooth yarn feeding, and at the same time, the ceramic pieces can be obtained by using the upper and lower plastic parts. The support is fixed, not only the yarn guide is smooth, but the yarn storage function can be completely flawless, and the function of the practical ceramic yarn feeding wheel is achieved.

The general ceramic yarn feeding wheel structure comprises an upper wheel cover and a lower wheel cover. The yarn feeding wheel is rotatably disposed under a frame body by a central shaft, and a yarn feeding column is arranged around the yarn feeding wheel. In the group, the yarn feeding column group comprises a plurality of circular ceramic columns, and the outer edge of each of the circular ceramic column storage yarn segments protrudes slightly outward, and the yarn is guided along the outer edge of the storage yarn segment when the yarn is fed. The yarn guiding section begins to slide down and is sequentially wound down the yarn storage section on the ceramic column before the yarn is discharged.

The above ceramic yarn feeding wheels still have the following disadvantages in actual use:

1. The roundness of the circular ceramic column is known, and the precision is difficult to grasp during the firing process.

2. It is known that the radial stress in the middle part of the circular ceramic column is quite fragile, and there are often breaks. When the yarn is wound around the yarn feeding wheel for storage, the problem of ceramic column fracture occurs. The yarn feeding operation is huge and needs to be improved.
