Detailed Implementation
[0015] Please see Figure 1 and Figure 3The synchronous drive device for rotating and translating the yarn guide disc provided in this application includes a spline shaft 1, a spline sleeve 2, and a translation mechanism 3; the spline shaft 1, the spline sleeve 2, and several rollers constitute a spline pair; the translation mechanism 3 includes a worm 31, a worm wheel 32, a worm wheel shaft 33, a transmission wheel 34, and a gearbox 35; the worm 31 is fixedly mounted on the spline sleeve 2; the gearbox 35 is mounted on the worm 31 via a housing bearing 36; the worm wheel shaft 33 is mounted inside the gearbox 35 via a worm wheel shaft bearing 37 and one end extends out of the gearbox 35; the worm wheel 32 is mounted on the worm wheel shaft 33 and located inside the gearbox 35; and the transmission wheel 34 is mounted at the extended end of the worm wheel shaft 33.
[0016] in: The worm gear 31 is provided with a bearing seat 311 and a shaft hole 312; the worm gear 31 is mounted on the spline sleeve 2 through the shaft hole 312; the housing bearing 36 is mounted on the bearing seat 311. The gearbox 35 is provided with a worm hole 351; the housing bearing 36 is also mounted in the worm hole 351.
[0017] The gearbox 35 is provided with a worm gear shaft hole 352; the worm gear shaft bearing 37 is disposed in the worm gear shaft hole 352; and the worm gear shaft 33 is disposed in the worm gear shaft bearing 37.
[0018] When the spline shaft 1 rotates, the spline sleeve 2 drives the worm 31 to rotate, which in turn drives the worm wheel 32 and the transmission wheel 34 to rotate. When the spline sleeve 2 rotates, it also drives the gearbox 35 and the worm 31 to move axially. Thus, the transmission wheel 34 can perform both rotational and linear motion. By connecting the transmission wheel 34 to the yarn support plate through a transmission belt or transmission chain, the synchronous drive of the rotation and translation of the yarn support plate can be achieved.
[0019] Depending on the number of pulls on the machine head, the number of spline shaft 1, spline sleeve 2, and translation mechanism 3 can be flexibly adjusted. Figure 1 The image shows a four-part yarn unloading machine head. When unloading yarn, four yarn support plates are needed to unload the yarn together. Correspondingly, four sets of spline pairs (including spline shaft 1 and spline sleeve 2) and corresponding translation mechanisms 3 are also needed for synchronous rotation and translation. Figure 1 It includes four splined shafts 1, four splined sleeves 2, and four translation mechanisms 3; the splined shafts 1 are coaxially connected by a synchronous shaft 4 to form the main drive shaft; the splined sleeves 2, the corresponding splined shafts 1, and rollers (which can be ball bearings or cylindrical rollers) constitute a spline pair; the translation mechanisms 3 are arranged on the corresponding splined sleeves 2 according to the above connection relationship. Driving the main drive shaft to rotate enables the rotation and translation of the four yarn-supporting discs through four transmission wheels 34.

It should be noted that those skilled in the art can develop other embodiments based on this.
