DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , a cloth winding mechanism of a rapier loom of the present invention, includes a bottom plate 1 and a winding shaft 2. Two limiting plates 3 are symmetrically arranged at both ends of the winding shaft 2. Two frames 4 are symmetrically arranged at the upper end of the bottom plate 1. An empty slot is provided at the top of the frame 4. A support rod 5 is arranged inside the empty slot. A chute 14 is provided at the lower end of the empty slot. A vertical rod 13 penetrating through the chute 14 is arranged at the lower end of the support rod 5. A first motor 10 is fixedly arranged on one of the frames 4. A first rotating shaft 11 is arranged at the output end of the first motor 10. Two screw rods 12 penetrating through the vertical rod 13 are symmetrically arranged on the first rotating shaft 11. The two screw rods 12 are of a reverse thread structure. A positioning shaft 6 is rotatably arranged on the support rod 5. A driving disc 7 is fixedly arranged at one end of the positioning shaft 6. A plurality of card slots 9 are arranged on the limiting plate 3. A plurality of card slots 9 cooperating with the clamping blocks 8 are arranged on the driving disc 7. A positioning frame 15 is fixedly arranged at the upper end of the frame 4. A second motor 16 is fixedly arranged on the positioning frame 15. A second rotating shaft 17 is fixedly arranged on the second motor 16. A driving shaft 18 is fixedly arranged on the second rotating shaft 17. A plurality of meshing blocks are arranged on the circumferential side of the driving disc 7. A plurality of meshing grooves are arranged on the circumferential side of the driving shaft 18. The driving shaft 18 meshes with the two driving discs 7;

[0024] In this embodiment, when the second motor 16 is started, the second rotating shaft 17 can drive the driving shaft 18 to rotate. Through the meshing effect, the driving shaft 18 can drive the two driving discs 7 to rotate synchronously, so that the winding shaft 2 can wind the specified cloth. During this process, through the cooperation of the clamping blocks 8 and the card slots 9, the driving disc 7 can stably drive the limiting plate 3 to move;

[0025] When the winding shaft 2 needs to be disassembled, the first motor 10 is started, so that the first rotating shaft 11 can drive the two screw rods 12 to rotate. At this time, through the action of the reverse thread structure, the two vertical rods 13 can move synchronously and in opposite directions along the two screw rods 12, so that the two support rods 5 can move synchronously.
