When high-pressure airflow is introduced into the inner side of the bending tube, the air outlet end of the bending tube sprays air onto the fan blades on both sides of the driving disk, causing the driving disk to rotate clockwise. When the weft thread is located inside the wire groove in the middle of the driving disk, a slider is provided on its upper side, and the bottom of the slider provides a limiting effect on the weft thread, so that the weft thread passes between the slider and the wire groove. When the rotating disk rotates under the drive of the high-speed airflow, it will carry the weft thread to the right side port of the weft guide drum of the air jet loom. At the same time, the slider is provided, and the distance between the bottom of the slider and the inner side of the wire groove can be adjusted by a threaded rod to meet the transportation requirements of weft threads of different diameters, so as to avoid the situation where the friction between the wire groove and the weft thread is too large, resulting in wire breakage, or the friction between the wire groove and the weft thread is too small, resulting in loose thread, thereby improving the applicability of the utility model.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-5 , a mixed weft introduction device for an air jet loom comprises a mounting plate 1, a support 6 is fixedly mounted on the right side of the mounting plate 1, and a weft guide drum 7 of the air jet loom is fixedly mounted on the support 6; a second rotating shaft 74 is rotatably mounted inside the weft guide drum 7 of the air jet loom, and a driving disk 75 is fixedly mounted on the second rotating shaft 74. A wire groove 76 is opened in the middle of the driving disk 75, and a plurality of fan blades 77 are equidistantly mounted on both sides of the driving disk 75. A slide groove 78 is opened on the upper side of the weft guide drum 7 of the air jet loom, and a slider 710 is slidably mounted inside the slide groove 78. A sealing cover 79 is fixedly mounted on the upper side of the slide groove 78, and a threaded rod 712 is screwed through the sealing cover 79. The lower end of the threaded rod 712 is rotatably connected to the slider 710. Bending tubes 713 are fixedly mounted on both sides of the weft guide drum 7 of the air jet loom, and the inner end of the bending tube 713 is bent toward the right side port of the weft guide drum 7 of the air jet loom.

[0033] In this embodiment, there are three groups of drive disks 75 and bent tubes 713 correspondingly provided. The outer ends of the three bent tubes 713 are connected to each other with a through tube 714, and an arc tube 715 is connected between the through tubes 714 on both sides. An air pump 8 is provided on the upper side of the support 6, and the air pump 8 is fixedly installed on the right side of the mounting plate 1. An air bleed pipe 9 and an air supply pipe 10 are installed on the air pump 8, and the air supply pipe 10 is connected to the arc tube 715.

[0034] Through the above structure, by starting the air pump 8, air is sucked in from the port of the air guide pipe 9, and the air is input into the bending pipe 713 through the air supply pipe 10, the arc tube 715 and the through pipe 714. Finally, a high-speed airflow is generated at the inner end of the bending pipe 713, and the high-speed airflow blows onto the fan blades 77 on the side of the driving disk 75, thereby driving the driving disk 75 to rotate at high speed inside the weft guide drum 7 of the air jet loom to perform the guide work.

[0035] In this embodiment, a notch 71 is provided at the left end of the weft thread guide drum 7 of the air jet loom. A first rotating shaft 72 is rotatably mounted inside the notch 71 , and a guide plate 73 is fixedly mounted on the first rotating shaft 72 .

[0036] Through the above structure, the setting of the guide plate 73 serves as a guide for the weft yarn on the weft yarn reel 3 to be transported to the weft yarn guide drum 7 of the air jet loom.

[0037] In this embodiment, the bottom of the slider 710 is located inside the wire groove 76 and the side of the slider 710 does not contact the inner wall of the wire groove 76 . A gasket 711 is installed at the bottom of the slider 710 .

[0038] The above structure reduces friction loss between the slider 710 and the inner side of the wire groove 76.

[0039] In this embodiment, a rotating torsion rod is fixedly mounted on the upper end of the threaded rod 712 .

[0040] The above structure facilitates the rotation of the torsion bar to drive the threaded rod 712 to rotate, thereby driving the slider 710 to move up and down, so as to change the distance between the bottom of the slider 710 and the inner side of the wire groove 76.

[0041] In this embodiment, a lug plate 2 is fixedly mounted on the side of the mounting plate 1 , and a mounting hole is formed on the lug plate 2 .

[0042] Through the above structure, the mounting plate 1 can be screwed onto the main frame of the air-jet loom through the mounting lugs 2 .

[0043] In this embodiment, a rotating rod 4 is provided on the lower side of the support 6 , a weft reel 3 is sleeved on the outer wall of the rotating rod 4 , and a limit buckle cover 5 is installed on the outer end of the rotating rod 4 .

[0044] Through the above structure, the rotating rod 4 provides a placement position for the weft reel 3. By removing the limiting buckle cover 5, the entire weft reel 3 can slide out from the side end of the rotating rod 4. This arrangement facilitates the replacement of the weft reel 3.

[0045] In the present invention, when in use, the air pump 8 is started, and air is sucked in through the air duct 9. The high-speed airflow flows into the bending tube 713 through the air delivery pipe 10, the arc tube 715 and the through tube 714. Finally, a high-speed airflow is generated at the inner end of the bending tube 713. The high-speed airflow acts on the fan blade 77, and the fan blade 77 drives the driving disk 75 to rotate instantaneously, driving the weft thread to be delivered to the right port of the weft thread guide drum 7 of the air jet loom. When the device is used to guide weft threads of different diameters, it is necessary to adjust the distance between the bottom of the slider 710 and the inner side of the wire groove 76 according to the actual production situation. To prevent the weft thread from loosening or breaking during threading, the specific adjustment process is to rotate the rotating torsion bar at the upper end of the threaded rod 712 to drive the threaded rod 712 to rotate, and the threaded rod 712 drives the slider 710 connected to the bottom end to slide inside the slide groove 78, so that the distance between the bottom of the slider 710 and the inside of the wire groove 76 changes. When the weft thread breaks during transportation, the distance between the bottom of the slider 710 and the inside of the wire groove 76 is appropriately adjusted. When the weft thread becomes loose during transportation, the distance between the bottom of the slider 710 and the inside of the wire groove 76 is appropriately reduced.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

Therefore, it is intended that all changes that fall within the meaning and range of equivalents of the claims are included in the present invention.
