To move, the frame yarn arm is installed on the hollow support shaft through the guide mechanism, one end of the push component is movably connected with the moving cam, and the other end of the push component is fixedly connected with the corresponding frame yarn arm so that when the moving cam is relative to the hollow support shaft When moving in the direction, the frame yarn arm moves radially relative to the hollow support shaft under the guidance of the guide mechanism.

Further provided is a structural form of the push assembly, the push assembly includes a cam guide rod and a cam roller, one end of the cam guide rod is fixedly connected with the corresponding frame yarn arm, and the cam roller is installed on the cam guide At the other end of the rod, the moving cam is provided with a pushing slope, and the cam roller abuts against the pushing slope.

Further, in order to make the pushing assembly move stably in the radial direction of the hollow support shaft and avoid sliding, the pushing slope of the moving cam is provided with guide grooves that are slidingly matched with the cam rollers.

Further, in order to adjust the expansion or contraction amplitude, frequency and strength, the power part is a cylinder, and the piston rod of the cylinder is connected with the push rod; the manufacturing cost of the cylinder is low, the environment is clean, and the operation is reliable.

A structural form of the guide mechanism is further provided, the guide mechanism includes a radial guide rod and a guide rod installation plate, the guide rod installation plate is installed on the hollow support shaft, and the radial guide rod is fixedly connected to the corresponding frame On the yarn arm, the radial guide rods are slidably fitted in the corresponding guide rod mounting discs.

A connection structure between the push rod and the moving cam is further provided and at the same time, the connection structure does not hinder the movement of the moving cam relative to the hollow support shaft, the hollow support shaft is provided with a cam movement groove, and the push rod The pin shaft is connected with the moving cam, and the pin shaft is inserted in the cam moving groove.

After adopting the above technical solution, the power part of the present invention moves, and when the push rod moves axially relative to the hollow support shaft, the moving cam also moves axially relative to the hollow support shaft, thereby causing the push assembly to move radially at the same time. The frame yarn arm moves radially along the hollow support shaft under the action of the guide assembly (expands or contracts inwards at the same time), so that the frame yarn covered on the frame yarn arm expands or contracts inwards, making the frame The yarn is fluffed and straightened, so as to meet the needs of winding, avoid the phenomenon of frame yarn breakage during the winding process, improve its production efficiency, and reduce the labor intensity of workers.
