Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] REFERENCE Figs. 1-3The utility model provides an embodiment: a kind of deviation rectification speed stable action mechanism of cloth drawing machine unwinding mechanism, including mounting bracket 1, the outer wall of mounting bracket 1 is fixedly connected with unwinding base, the inside of mounting bracket 1 is provided with deviation rectification cylinder 2, the output end of deviation rectification cylinder 2 is fixedly connected with connecting plate one 3, the inside of mounting bracket 1 is provided with damping cylinder 4, the output end of damping cylinder 4 is fixedly connected with connecting plate two 5, the inside tail of damping cylinder 4 is provided with needle type throttle valve one 7, the inside of damping cylinder 4 is provided with needle type throttle valve two 8, the outer wall of mounting bracket 1 is provided with oil supply component, and oil supply component is used to the effect of oil supply to damping cylinder 4.

[0020] Specifically, mounting bracket 1 is installed on unwinding base, connecting plate one 3 and connecting plate two 5 are fixed with unwinding mechanism simultaneously, when needing to adjust, deviation rectification cylinder 2 is started to push connecting plate one 3 to move, and then make connecting plate one 3 push unwinding mechanism to move, since connecting plate one 3 and connecting plate two 5 are connected with unwinding mechanism, then drive connecting plate two 5 to move, when connecting plate two 5 moves, damping cylinder 4 is compressed or extended, hydraulic oil in oil reservoir 6 is under the action of pressure and enters the chamber of damping cylinder 4, the cooperation of needle type throttle valve one 7 and needle type throttle valve two 8 and since the incompressibility of hydraulic system, the movement speed of the whole mechanism depends on the speed of damping cylinder 4, so that the stable effect of the deviation rectification movement of the whole unwinding mechanism is realized.

[0021] Referring to Figs. 1-3 , oil supply component includes oil reservoir 6, and the oil outlet of oil reservoir 6 is fixedly connected to the oil inlet of damping cylinder 4.

[0022] Specifically, hydraulic oil in oil reservoir 6 flows into the chamber of damping cylinder 4 due to pressure, and flows back into oil reservoir 6 under the action of pressure, and since the incompressibility of hydraulic system, the whole operation is more stable.

[0023] Referring to Figs. 1-3 , the outer wall of connecting plate one 3 is fixedly connected with unwinding movable mechanism, and the outer wall of connecting plate two 5 is fixedly connected with unwinding movable mechanism. Connecting plate one 3 and connecting plate two 5 are in the same horizontal line. Connecting plate one 3 and connecting plate two 5 move simultaneously.

[0024] Specifically, connecting plate one 3 is moved by deviation rectification cylinder 2, and then unwinding movable mechanism is moved, since connecting plate one 3 and connecting plate two 5 are connected with unwinding movable mechanism, connecting plate one 3 moves simultaneously, and then connecting plate two 5 is moved, and then damping cylinder 4 is compressed or extended.

[0025] Working principle: when the structure needs to be used, first install the mounting bracket 1 on the unwinding base, so that the position of the deviation correction cylinder 2 and the damping cylinder 4 is fixed, then fix the connecting plate one 3 and the connecting plate two 5 on the unwinding movable mechanism, when the deviation correction mechanism needs to be used, start the deviation correction cylinder 2, the deviation correction cylinder 2 pushes the connecting plate one 3 to move, so that the connecting plate one 3 pushes the unwinding movable mechanism to move, and further drives the connecting plate two 5 to move, when the connecting plate two 5 moves, it will compress the damping cylinder 4 inward or extend the damping cylinder 4 outward, at this time, the hydraulic oil in the oil reservoir 6 enters the chamber of the damping cylinder 4 or flows into the inside of the oil reservoir 6 under the action of pressure, by adjusting the speed of the damping cylinder 4 extending and retracting, rotating the needle type throttle valve one 7 clockwise, the valve opening degree becomes smaller, at this time, the flow of hydraulic oil entering the piston front chamber of the damping cylinder 4 is reduced, and the speed of the piston extending will be reduced, if the needle type throttle valve one 7 is rotated counterclockwise, the valve opening degree increases, the hydraulic oil flow increases, and the piston extending speed will be improved, when the piston retracts, the fluid flows back from the other side of the piston through another channel, adjusting the needle type throttle valve two 8 controlling the retraction action, which will also change the channel cross-sectional area, the change of the cross-sectional area will cause the change of the fluid backflow speed, and then control the speed of the piston retracting, by adjusting the cooperation of the needle type throttle valve one 7 and the needle type throttle valve two 8 and due to the incompressibility of the hydraulic system, the movement speed of the whole mechanism depends on the speed of the damping cylinder 4, so as to realize the stable effect of the deviation correction movement of the whole unwinding mechanism.
