[0029] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-6 In the embodiment of the present application, a large circular weaving machine anti-winding mechanism comprises a large circular machine 1, and a winding mechanism 2 is arranged below the large circular machine 1; the winding mechanism 2 comprises two side vertical plates 21, and a transmission roller 22 is movably connected between the two side vertical plates 21 through bearings; one side of the transmission roller 22 is provided with a protection assembly 24, and the protection assembly 24 comprises two sliding blocks 243 arranged at two ends of an auxiliary roller 23; the sliding block 243 is connected with the auxiliary roller 23 in a matched mode, and the sliding block 243 is slidably connected in a sliding groove 242;

[0031] A sliding plate 245 is arranged outside the sliding block 243; a convex shaft is welded on one side of the sliding plate 245 away from the sliding block 243, and a threaded cylinder 246 is sleeved on the convex shaft;

[0032] A connecting rod 249 is further fixed between the two side vertical plates 21, and a clamping seat 2410 is fixed at both ends of the connecting rod 249; a micro switch 241 is fixed on one side of the clamping seat 2410, and a transmitter 2411 is fixed at the bottom of the clamping seat 2410; the transmitter 2411 is electrically connected with a controller for controlling the opening and closing of a winding motor.

[0033] By adopting the above technical scheme, when the cloth is wound between the transmission roller 22 and the auxiliary roller 23 during the winding process of the cloth, the thickness of the cloth is increased due to the winding of the cloth on the transmission roller 22, so that the gap between the transmission roller 22 and the auxiliary roller 23 is increased, at this time, the sliding block 243 at both ends of the auxiliary roller 23 pushes out the sliding plate 245, and the sliding plate 245 slides outward along the sliding groove 242 after the compression spring 244 is compressed.

[0034] When the auxiliary roller 23 touches the micro switch 241, the micro switch 241 circuit is turned on, the transmitter 2411 transmits a signal, and the controller receives the signal and quickly controls the motor to stop working; the cloth winding is effectively prevented from being excessively wound to cause large-area damage.

[0035] The sliding plate 245 is slidably connected in the sliding groove 242; the spring 244 is clamped on the threaded cylinder 246 at the end away from the sliding plate 245, the threaded cylinder 246 is internally threadedly connected with the screw rod 247; the screw rod 247 is connected with the side stand 21 through the bearing with seat 248 at one end.

[0036] Normally, the spring 244 has a pushing force on the sliding plate 245, ensuring the tightness of the transmission roller 22 and the auxiliary roller 23, thereby facilitating the transmission of the woven fabric; the spring 244 can be self-adaptively adjusted according to the thickness of the fabric;

[0037] The spring force of the spring 244 can be adjusted by rotating the screw rod 247 to adjust according to the fabric of different thicknesses.

[0038] In the embodiment, a cross bar 211 is welded between the two side stands 21, and a fixed block 210 is fixed on the cross bar 211; the fixed block 210 is installed on the rotating table 4; the rotating table 4 is fixed on the base 5.

[0039] The rotating table 4 can make the winding mechanism 2 rotate the woven fabric with the large circular machine 1.

[0040] In the embodiment, the base 5 has three extension arms, and a stand is welded on each extension arm, and a protective cover 3 is fixed outside the stand; the protective cover 3 has an opening for the operator to enter.

[0041] In the embodiment, the transmission roller 22 is installed at one end with a driving motor, and the driving motor is fixed outside the side stand 21, and the other end of the transmission roller 22 penetrates into the cavity of the other side stand 21 and is installed with a pulley 27;

[0042] The pulley 27 is provided with two, and the other pulley 27 is installed on the connecting cover 29; the two pulleys 27 are drivingly connected through the belt 28; the connecting cover 29 is convexly arranged and is connected with the supporting arm 25 through a bearing.

[0043] By adopting the above technical scheme, when the transmission roller 22 and the auxiliary roller 23 transmit the woven fabric, the rotation of the connecting cover 29 is realized under the cooperation of the two pulleys 27 and the belt 28;

[0044] Since the two connecting covers 29 are clamped with the winding roller 26, the rotation of the winding roller 26 can be realized, and the winding of the fabric can be realized; the two ends of the winding roller 26 are fixed with the two connecting covers 29 through bolts; thus, the disassembly of the wound winding roller 26 is facilitated.

[0045] The working principle of the utility model is: when using, the large circular machine 1 weaves the cloth, the well-woven cloth extends downward, passes between the transmission roller 22 and the auxiliary roller 23, and then is wound on the winding roller 26 for winding; when the transmission roller 22 and the auxiliary roller 23 transmit the well-woven cloth, the rotation of the connecting cover 29 is realized under the cooperation of the two pulleys 27 and the belt 28; the winding roller 26 is clamped between the two connecting covers 29; thus the rotation of the winding roller 26 can be realized, and the cloth can be wound.

[0046] In the process of winding the cloth, if the cloth is wound between the transmission roller 22 and the auxiliary roller 23, because the cloth is wound on the transmission roller 22, the thickness increases, the gap between the transmission roller 22 and the auxiliary roller 23 increases, at this time, the sliding block 243 at the two ends of the auxiliary roller 23 outwardly jacks up the sliding plate 245, and the compression spring 244 slides outward along the sliding groove 242.

[0047] When the auxiliary roller 23 touches the micro switch 241, the micro switch 241 circuit is turned on, the transmitter 2411 emits a signal, and the controller receives the signal and rapidly controls the motor to stop working; the situation that the cloth is excessively wound and large area damage occurs can be effectively avoided.
