In the prior art, the second driving part 36 (or called heald box) is generally installed on top, and adopts a sprocket transmission, for example, the prior application 201410500978.4 of the present inventor adopts a scheme that has the following drawbacks: the chain transmission makes the rotational speed of the heald lifting driving mechanism unable to be further improved, and the existing heald lifting driving mechanism is installed in an upper position, the connection clearance is larger, resulting in poor stability, and meanwhile, the early assembly and the later maintenance are not facilitated, but the application adopts the heald lifting driving shaft 41 to drive the heald lifting arm 15 to move up and down, as shown in fig. 1, the driving part II 36 can be installed in a lower position (directly placed on the ground), the connection clearance is reduced, the stability is improved, the later maintenance is facilitated, meanwhile, the common weft cam transmission is adopted, and a proper transmission ratio is obtained through gears, so that the transmission speed can be greatly improved.
The transmission gear set comprises an input gear 51 fixed on the second input shaft 39, a third transmission shaft 52 rotatably connected with the box body, and a second output gear 54 fixed on the second output shaft 40, wherein a fourth transmission gear 55 meshed with the input gear 51 and a fifth transmission gear 56 meshed with the second output gear 54 are fixed on the third transmission shaft 52. Preferably, the diameter ratio among the input gear 51, the fourth transmission gear 55, the fifth transmission gear 56 and the second output gear 54 in this embodiment is 1:2:1:1.5 in order.
The power transmission route of the second driving portion 36 is as follows: external power is transmitted to the input gear 51 through the input shaft II 39, the input gear 51 transmits power to the output shaft II 40 through the transmission gear IV 55, the transmission gear V56 and the output gear II 54 in sequence, the output shaft II 40 drives the common weft cam I45 and the common weft cam II 46 to rotate, the swing block I47 and the swing block II 48 are driven to swing back and forth under the action of the connecting rod I43 through the rotation of the common weft cam I45 and the common weft cam II 46, the swing of the swing block I47 drives the heald lifting driving shaft 41 to rotate back and forth under the action of the connecting rod II 44, and the back and forth rotation of the heald lifting driving shaft 41 drives the heald frame to move up and down through the heald lifting arm 15 as shown in fig. 1. The embodiment can adjust the amplitude and frequency of the up-and-down motion of the heald frame by changing the shape or relative angle of the four common weft cams, and compared with the prior art, the embodiment replaces chain transmission by common weft cam transmission, and obtains proper transmission ratio by gears, so that the transmission speed can be greatly improved. In addition, due to the two cam transmission mechanisms and the two heald lifting driving shafts 41, the two heald frames can be driven to move up and down respectively, and the user can adjust the up-down movement amplitude and frequency of the two heald frames respectively according to actual requirements.
The motion process of the heald frame structure is as follows: the left and right moving rod 21 of the first driving part 35 is connected with the left and right moving transmission rod 14, the second driving part 36 is hinged with the first connecting plate 7 below the front heald frame 2 through one heald lifting driving shaft 41 and the heald lifting arm 15, and is hinged with the second connecting plate 8 below the rear heald frame 3 through the other heald lifting driving shaft 41 and the heald lifting arm 15, and fig. 16 and 17 are connecting structures between the heald lifting arm 15 and the heald lifting output shaft, the first connecting plate 7 or the second connecting plate 8. The first driving part 35 drives the left-right movement transmission rod 14 to move left and right, the left-right movement transmission rod 14 drives the front heald frame 2 to move left and right through the upper connecting plate 9 and the lower connecting plate 10, and the sliding rod 6 slides back and forth in the oblong hole 5 on the fixed block when the front heald frame 2 moves left and right; the second driving part 36 drives the heald lifting driving shaft 41 to rotate back and forth within a certain angle, so as to drive the heald lifting arm 15 to move up and down, and the up and down movement of the heald lifting arm 15 drives the corresponding front and back heald frames 3 to move up and down, and when the front heald frame 2 moves up and down, the chute seat 11 moves back and forth relative to the first roller 12. Since the first connecting plate 7 moves left and right in the oblong hole 5 through the sliding rod 6, the first roller 12 rolls in the sliding groove, so that the left and right movement and the up and down movement of the front heald frame 2 are not mutually influenced.
As shown in fig. 15, the lifting arm 15, the first connecting rod 43 and the second connecting rod 44 in the application all comprise a connecting block 57, two through holes are formed in the connecting block 57, a screw rod 58 penetrates through the through holes, and nuts 59 are connected to the screw rod 58 in a threaded manner on two sides of the through holes. The length of the first link 43, the second link 44 or the heald lifting arm 15 can be adjusted at any time by rotating the nut 59, the movement amplitude of the corresponding parts can be adjusted by changing the length, for example, the swing amplitude of the first swing block 47 and the second swing block 48 can be changed by adjusting the length of the first link 43, the swing amplitude of the heald lifting drive shaft 41 can be adjusted by adjusting the length of the second link 44, and the amplitude of the up-and-down movement of the front and rear heald frames 3 can be adjusted by adjusting the length of the heald lifting arm 15.
