[0060] During operation, the operator operates the control panel 2 to accurately control the warp yarn tube 7, the weft yarn conveying part 8 and the bottom line conveying part 9 to automatically transport the warp yarn, the weft yarn and the bottom line respectively with electronic signal instructions. The first driving component 4 drives the reed device 3 to move up and down, thereby prompting the reed device 3 to adjust the change of the interval seam width of the warp yarn, and then cooperates with the second driving component 6 to drive the weft yarn hook device 5 to move left and right to adjust the supply of the weft yarn. A large supply of yarn will make the ribbon wider, and a small supply of yarn will make the ribbon narrower. It is fully automatic, and there is no need to stop for adjustment. The width of the ribbon is adjusted instantly to weave finished products of different widths. The present invention realizes automatic weaving of wide and narrow ribbons, regularly adjusts the ribbon width according to actual work needs, has high work efficiency, and meets the mass production needs of wide and narrow ribbons.

Specifically, the first connecting rod 34 and the second connecting rod 35 are respectively installed at the two ends of the reed shaft 31, the reed piece 33 is sleeved on the reed shaft 31 through the reed seat 32, the first connecting rod 34 is hinged to the first hinge seat 11 through the first hinge shaft 13, and the second connecting rod 35 is hinged to the second hinge seat 12 through the second hinge shaft 14. According to the lever principle, when the first driving component 4 synchronously drives the first connecting rod 34 and the second connecting rod 35 to move forward and backward through the transmission rod 36, with the first hinge shaft 13 and the second hinge shaft 14 as the rotation fulcrum, the first connecting rod 34 and the second connecting rod 35 drive the reed shaft 31 to adjust the up and down position, and further adjust the change of the width of the warp yarn interval seam through the different widths of the interval seams of the reed piece 33.

[0062] like Figure 2 and Figure 3As shown, the steel reed seat 32 of this embodiment is provided with a plurality of steel reed seats 32 and arranged at intervals along the length direction of the steel reed shaft 31, a mounting hole 321 is opened in the middle of the steel reed seat 32, a slot 322 is opened on the outer side of the steel reed seat 32, the slot 322 is arranged along the length direction of the steel reed seat 32 and connected with the mounting hole 321, a connecting hole 323 is opened on the outer side of the steel reed seat 32, and the central axis of the mounting hole 321 is arranged perpendicular to the central axis of the connecting hole 323. Specifically, the reed shaft 31 is stably mounted on the frame 1, and a plurality of reed parts 33 are correspondingly mounted on a plurality of reed seats 32. The plurality of reed seats 32 are arranged at intervals along the length direction of the reed shaft 31. The reed seat 32 is inserted into the reed shaft 31 through the mounting hole 321 and slides along the length direction of the reed shaft 31. The reed seat 32 is threadedly connected with the connecting hole 323 through an external screw. By shrinking the gap of the notch 322, the reed seat 32 can be clamped and fixed to the appropriate position of the reed shaft 31 according to actual work needs. The connection is stable and reliable, and loading and unloading are convenient.

Specifically, when the width of the webbing needs to change, the first connecting rod 34 and the second connecting rod 35 drive the reed shaft 31 to adjust the upper and lower positions, and then move the reed piece 33 up and down to adjust the working position. When the reed piece 33 moves up to a high position, multiple warp threads are guided by the wide gap 336 to widen the arrangement width of the multiple warp threads. At this time, the weft yarn hook device 5 moves left and right to adjust the supply of weft yarn. A large supply of weft yarn will make the webbing wider, thereby forming a wide part of the webbing; when the reed piece 33 moves down to a low position, multiple warp threads are guided by the narrow gap 338 to narrow the arrangement width of the multiple warp threads. At this time, the weft yarn hook device 5 moves left and right to adjust the supply of weft yarn. A small supply of weft yarn will make the webbing narrower, thereby forming a narrow part of the webbing. The transition gap 337 between the wide gap 336 and the narrow gap 338 helps the warp threads to pass through and move, thereby meeting the working requirements of instantaneous width changes of the webbing.

The second driving component 6 is drivingly connected to the translation member 524. Specifically, the bottom line is automatically fed through the bottom line transmission part 9, and the locking effect of the webbing is changed by adjusting the bottom line feeding speed, and then the bottom line assembly 53 is cooperated to realize automatic weaving of the bottom line. Multiple warp yarns pass through the reed device 3 and are guided and sorted along the guide plate 514, and pass through the gap between the guide plate 514 and the clamping plate 515. The clamping plate 515 is pressed and positioned on the upper surface of the multiple warp yarns, and the multiple warp yarns are sorted for stable and reliable transportation. When the reed part 33 is moved up and down to adjust the working position, the second drive assembly 6 drives the hook needle axis 521 to move left and right through the translation part 524, and then drives the weft hook needle 523 to move left and right to adjust the supply amount of the weft yarn, so as to better cooperate with the reed part 33 to adjust the arrangement width and narrowness of the warp, which is beneficial for the weaving needle 512 to interweave multiple warp yarns and weft yarns into wide and narrow belts, thereby improving weaving efficiency.
