[0002] The guide and conveying system of an air-jet loom plays an important role in ensuring fabric quality, improving production efficiency, reducing weft tension unevenness and weft shrinkage, improving loom stability and energy saving and environmental protection, etc. However, the current guide and conveying assembly still has some deficiencies when in use.

[0003] Chinese Patent Application No. 202323576875.X discloses a guide and conveying assembly for an air-jet loom, which comprises a base. First sliding grooves are formed in the middle of the upper side wall on one side near the front side position and on one side near the rear side position. The two first sliding grooves are mirror-image opposite. A protection block is installed on the middle of the upper end of one side wall of the base. A double-shaft motor is installed on the middle of the inner side wall bottom of the protection block. In the present application, the two output ends of the double-shaft motor drive two driving gears to rotate synchronously clockwise or counterclockwise, thereby driving two driven gears to rotate. Two groups of support shafts support and limit the two groups of driven gears. The two groups of driven gears drive two lead screws to rotate synchronously, thereby driving the first shafts connected between the two movable seats, the first mounting seat installed on the upper side wall and the two movable rear beams to move, thereby stretching the tension.
