DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See also Figure 1-Figure 4 ,

[0040] A three-warp tang loom with fixed and rotating combined weft insertion includes a drive cabinet 1 and a sword wheel 22 rotatably mounted on the drive cabinet 1 through an output shaft 21. A sword belt 23 is wound on the sword wheel 22. In this embodiment, the sword belt 23 is slidably arranged in a guide rail 26. The guide rail 26 guides and directs the sword belt 23. On the one hand, it prevents the sword belt 23 from detaching from the sword wheel 22 to ensure the stability of weft insertion. On the other hand, it also increases the "rigidity" of the sword belt 23.

[0041] like Figure 1 As shown, an active cone 4 is rotatably arranged in the driving cabinet 1, and the active cone 4 is driven to rotate by the input shaft 3, and the input shaft 3 is the power shaft of the loom;

[0042] The driven cone 5 is rotatably arranged in the driving cabinet 1 through the driven shaft 12. In the present invention, a partition 2 is fixedly installed in the driving cabinet 1, and the partition 2 divides the internal space of the driving cabinet 1 into a power cavity and a transmission cavity. The active cone 4 and the driven cone 5 are both rotatably arranged in the power cavity.

[0043] In addition, a power transmission mechanism is provided between the active cone 4 and the driven cone 5, and the power transmission mechanism is used to transmit the power of the active cone 4 to the driven cone 5;

[0044] In the present invention, the power transmission mechanism includes a rubber wheel 6, a bearing 7 and a nut 8. Figure 2As shown, the edges of the active cone 4 and the driven cone 5 on opposite sides are parallel to each other, the rubber wheel 6 is rotatably arranged between the active cone 4 and the driven cone 5, and the rubber wheel 6 is rotatably mounted on the nut 8 through the bearing 7;

[0045] Furthermore, the nut 8 is threadedly connected to the screw rod 9, the screw rod 9 is rotatably arranged in the drive cabinet 1, and one end of the screw rod 9 extends to the outside of the drive cabinet 1 and is fixedly connected to the adjustment button 10, and a limit rod 11 is also inserted in the nut 8, and the limit rod 11 is fixedly installed in the drive cabinet 1;

[0046] Turning the adjusting knob 10 can rotate the screw rod 9, and the rotation of the screw rod 9 drives the nut 8 to move. By adjusting the nut 8 and the rubber wheel 6 to different positions, the power transmission ratio between the active cone 4 and the driven cone 5 can be controlled, thereby controlling the rotation speed of the driven cone 5.

[0047] In this embodiment, the rotation speeds of the input shaft 3 and the active cone 4 remain unchanged, and the speed of the driven cone 5 can be controlled by adjusting the position of the rubber wheel 6 in an infinitely adjustable manner.

[0048] In the present invention, if Figure 2 and Figure 4 As shown, a reciprocating swing mechanism is provided between the driven shaft 12 and the output shaft 21, and the reciprocating swing mechanism is used to drive the output shaft 21 to swing back and forth;

[0049] Specifically, the reciprocating swing mechanism includes a driving bevel gear 13, a driven bevel gear 14, a vertical shaft 15, a rotating arm 16, a connecting rod 17, a sector gear plate 18, a central shaft 19 and a driving gear 20. The driving bevel gear 13 is fixedly mounted on the end of the driven shaft 12, and the outer wall of the driving bevel gear 13 is meshed with the driven bevel gear 14. The driven bevel gear 14 is rotatably mounted in the driving cabinet 1 through the vertical shaft 15.

[0050] A rotating arm 16 is fixedly installed at the center of the top of the driven bevel gear 14, and the end of the rotating arm 16 is rotatably connected to a connecting rod 17, and the end of the connecting rod 17 is rotatably installed on a sector-shaped toothed plate 18, and the sector-shaped toothed plate 18 is rotatably installed in the drive cabinet 1 through a central shaft 19. The outer wall of the sector-shaped toothed plate 18 is meshed with a driving gear 20, and the driving gear 20 is fixedly installed on an output shaft 21, and the output shaft 21 is rotatably installed in the drive cabinet 1;

[0051] When the driven cone 5 rotates, the active bevel gear 13 is synchronously driven to rotate through the driven shaft 12. The rotation of the active bevel gear 13 drives the driven bevel gear 14 meshed with its outer wall to rotate. The rotation of the active bevel gear 13 drives the rotating arm 16 to rotate. When the rotating arm 16 rotates, the connecting rod 17 can pull / push the sector tooth plate 18 to make the sector tooth plate 18 swing back and forth. The reciprocating swing of the sector tooth plate 18 drives the driving gear 20 to cycle back and forth in forward and reverse rotation, and then the output shaft 21 is used to make the sword wheel 22 cycle back and forth in forward and reverse rotation. The sword wheel 22 can send out the sword belt 23 or retract the sword belt 23 by reciprocating in forward and reverse rotation.

[0052] In the present invention, through the fixed reciprocating swing mechanism and the rotating power transmission mechanism, the reciprocating rotation of the sword wheel 22 can be precisely controlled, thereby realizing the control of the movement of the sword belt 23 and the sword head. The power transmission is stable and the failure rate is low. At the same time, the overall structure is simple, compact and small in size, which realizes the lightweight and precision of the weft insertion mechanism of the loom and reduces the occupied space.

[0053] In the present invention, the power of the input shaft 3 is transmitted through the active cone 4, the power transmission mechanism and the driven cone 5. By adjusting the position of the rubber wheel 6 in the power transmission mechanism, the rotation speed of the driven cone 5 can be regulated, and then the rotation speed of the sword wheel 22 can be controlled, so that the infinite adjustment of the sword head movement speed can be achieved to meet the movement requirements of the beating mechanism.

[0054] Embodiment 2:

[0055] See also Figure 5 and Figure 6 On the basis of the first embodiment, an auxiliary wheel 24 is further provided in this embodiment. The auxiliary wheel 24 rotates synchronously and counter-rotatingly with the sword-leading wheel 22. A belly belt 25 is wound around the auxiliary wheel 24. The belly belt 25 fits with the sword belt 23 and is slidably provided together in the guide rail 26.

[0056] Thus, when the sword belt 23 is extended, the belly belt 25 is also extended, and when the sword belt 23 is retracted, the belly belt 25 is also retracted. In addition, during the movement, the belly belt 25 slides together with the sword belt 23 on the guide rail 26, cooperates with the sword belt 23, and is synchronized on the movement path. This allows the sword belt 23 to have its original flexibility while also enhancing its rigidity due to the addition of the belly belt 25, making it less likely to crack or break, thereby extending the service life of the sword belt 23. At the same time, this modification does not require material improvements to the sword belt 23, and is low in cost.

[0057] In the present invention, a slide bar is fixedly provided on the side of the belly band 25, and the slide bar is slidably provided in a slide groove 27, and the slide groove 27 is provided on the inner wall of the guide rail 26, and the sword belt 23 is pressed in the guide rail 26 by the belly band 25;

[0058] By setting the slide bar and the slide groove 27, the belly belt 25 can be effectively positioned, and then the position of the sword belt 23 is also positioned. Since the slide bar is set on the belly belt 25, there is no structural disturbance to the sword belt 23, and an ordinary sword belt 23 can be used.

[0059] like Figure 5 As shown, the auxiliary wheel 24 is rotatably mounted on the drive cabinet 1 through the secondary shaft 28, a synchronous wheel 29 is fixedly mounted on the output shaft 21, and a synchronous wheel 2 30 is fixedly mounted on the secondary shaft 28. The synchronous wheel 1 29 is meshed with the synchronous wheel 2 30. When the output shaft 21 rotates, the synchronous wheel 1 29 is also driven to rotate. The rotation of the synchronous wheel 1 29 drives the synchronous wheel 2 30 to rotate, thereby enabling the secondary shaft 28 and the auxiliary wheel 24 to rotate, and the auxiliary wheel 24 and the sword guiding wheel 22 rotate synchronously and in the opposite direction. The transmission system is simple and efficient.

[0060] In this embodiment, soft magnetic strips that attract each other can be provided on the sword belt 23 and the belly belt 25. Through the arrangement of the soft magnetic strips, the fit between the sword belt 23 and the belly belt 25 can be further improved without affecting the original functions of the sword belt 23 and the belly belt 25, and they can also be separated freely.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
