A discharge port 19 is provided at the bottom of the buffer cavity 12, and the bottom of the discharge port 19 is connected to a material bag 20. When the air inlet 13 sucks in the weft yarn, it is inevitable to suck in waste materials. The waste materials can enter the material bag 20 and are cleaned regularly. The air blowing pipe 21 is obliquely arranged in the side wall of the air cavity 28 from the air inlet valve 14 to the buffer cavity 12 at the rear of the air cavity 28. A buffer pad 22 is arranged between the rear end of the buffer cavity 12 and the inner wall of the operation box 27, and a bracket 29 is provided at the connection between the bottom of the air cavity 28 and the inner wall of the operation box 27. An air pump 24 is provided at the bottom of the operating box 27, and the air pump 24 is connected to the connector 16 on the side of the air inlet valve 14 through the air pipe 23. The longitudinal inner diameter of the inner cavity of the air cavity 28 is smaller than the longitudinal inner diameter of the inner cavity of the buffer cavity 12. A weft yarn traction device 11 is installed in the operating box 27 provided on one side of the frame 2. When the jet device 1 sprays the weft yarn, the weft yarn traction device 11 can absorb the thread end in time, and then the scissors 31 cut the weft yarn, which can prevent the weft yarn from curling during the weft beating process and improve the beauty of the woven fabric. An air inlet valve 14 and a plug 15 are provided in the weft yarn traction device 11. The plug 15 moves up and down in the air inlet valve 14 to control the opening and closing of the air inlet valve 14.

When the device is weaving, the weft is fed through the jet device 1, and the warp is fed through the upper and lower heald frames 4. At the same time, the weft traction device 11 cooperates with the jet device 1 to avoid curling of the weft. The overall operation of the device requires less manpower, has high efficiency, and improves the appearance of the weaving sample.

[0030] When the device is used, the weft on the creel 10 enters the jet device 1 from the weft accumulator 9, and when the warp enters from the upper and lower heald frames 4, the weft is ejected through the jet device 1. At the same time, the cylinder 18 in the weft traction device 11 controls the plug 15 to move up through the connecting rod 17, and the air inlet valve 14 is connected with the connector 16. The air pump 24 takes air into the blowing pipe 21 through the connector 16, and a negative pressure is formed in the air cavity 28 and the buffer cavity 12. The suction port 13 sucks the weft head sprayed from the jet device 1, and the beating mechanism 6 beats the weft. The scissors 31 cut the weft that has been beaten, and the beating mechanism 6 is reset. When the scissors 31 cut the weft in the weft traction device 11, the plug 15 has moved down to block the air inlet valve 14. When the weft is ejected from the blowing device 1 again, the above actions are repeated until the weaving sample is completed.
