The utility model relates to the technical field of textile, and discloses a pneumatic yarn transmission mechanism, which comprises a multidirectional cylinder frame, a pneumatic transmission mechanism, a pneumatic transmission mechanism, a pneumatic transmission mechanism, a pneumatic transmission mechanism, a pneumatic transmission mechanism and a pneumatic transmission mechanism, and is characterized in that the multidirectional cylinder frame has multiple orientations and is internally used for transmitting yarn bodies; the inner transmission wheel is rotationally arranged in the multidirectional cylinder frame and is used for guiding a wire body; the inlet cover is detachably fixed at the input end of the multidirectional cylinder rack wire body; and the outlet cover is detachably fixed to the output end of the multidirectional barrel rack wire body, and two sets of clamping wheels are arranged on the inner side of the outlet cover, used for clamping the wire body and driven by gas to rotate. According to the utility model, through full-section uniform stretching, stress concentration reduction and the synergistic effect of the multidirectional cylinder frame and the pneumatic driving clamping wheel, multidirectional synchronous stretching of yarns is realized, and the clamping wheel is driven by airflow to generate relative rotation, so that the yarns are uniformly pulled in the multidirectional cylinder frame, single-point stress concentration is avoided, the problem of preferential breakage of outer-layer fibers is effectively solved, and the production efficiency is improved. The quality is obviously improved.

The utility model discloses a based on the double circle track of flexible initiative barrier formula carrier trolley of variable diameter, including chassis component, walking wheel subassembly, walking wheel power system subassembly and flexible clamping system subassembly, and walking wheel subassembly includes four walking wheels of matrix arrangement, walking wheel power system subassembly is connected with four walking wheels, is used for driving four walking wheels and walks on double circle track, flexible clamping system subassembly includes four guide wheels and guide drive system of four guide wheels are connected with opposite settings, and guide wheel can roll along the inner wall of double circle track both sides, and guide drive system can adjust guide wheel automatic keep with the inner wall of double circle track constant pressure contact according to the size between the inner wall of double circle track. Based on the double circle track of flexible initiative barrier formula carrier trolley of variable diameter, has solved the technical problem of traditional rigid structure easy to jam, derailment on the double circle track, and has high stability, strong environmental adaptability simultaneously.
