Embodiment 1

[0017] Referring to Fig. 3~4, the reed width increasing device of the weft insertion mechanism of the invention rapier loom mainly consists of a sector gear 1, an intermediate gear pair, a shaft gear 7 and a sword wheel 8. A sword belt 9 is arranged on the sword wheel 8, and a sword head 10 is arranged on the sword belt 9. The intermediate gear pair mainly consists of intermediate wheel 2, transmission gear I 4, transmission gear II 6 and shaft 5. The intermediate wheel 2 is installed on the optical axis section of the shaft gear 7 through the rolling bearing I 3, the shaft gear 7 is coaxial with the sword wheel 8, the transmission gear I 4 and the transmission gear II 6 are installed on the shaft 5 through the shaft sleeve 11 and the rolling bearing II 12, The sector gear 1 meshes with the intermediate wheel 2, the intermediate wheel 2 meshes with the transmission gear I 4, and the transmission gear II 6 meshes with the shaft gear 7.

Embodiment 2

[0020] Referring to Figures 5-6, in this embodiment, the intermediate gear pair in Embodiment 1 is changed from the intermediate gear 2, the transmission gear I 4, the transmission gear II 6 and the shaft 5 to a dual gear I 13, a dual gear II 14 and axis 5. Dual gear 13 is mounted on the optical axis section of shaft gear 7 through rolling bearing I 3 , and dual gear II 14 is mounted on shaft 5 through rolling bearing II 12 . The sector gear 1 meshes with the pinion in the dual gear I 13, the large gear in the dual gear I 13 meshes with the small gear in the dual gear II 14, and the large gear in the dual gear II 14 meshes with the shaft gear 7 meshing.

[0021] When the weft insertion mechanism moves, the sector gear 1 swings back and forth accordingly, and the swing motion of the sector gear 1 is transmitted to the dual gear I 13, and the dual gear I 13 transmits the swing motion to the dual gear II 14, and the dual gear II 14 transmits the swing motion to the shaft gear 7...

Abstract

The invention involves a reed space-increasing device of gripper loom weft insertion device, it includes fan gear (1), axle gear (7) and gripper-transmitting wheel (8), the axle gear (7) and the gripper-transmitting wheel (8) are coaxial, it is characterized by: a middle gear pair is added between said fan gear (1) and axle gear (7), the fan gear (1)is engaged with the middle gear pair, and the middle gear pair is engaged with the axle gear (7). The invention uses the middle gear pair driven by fan gears, so increases the swiveling speed of axle gear many times, that is the invention can increase the working strokes of gripper belt and gripper head of gripper wheel and realized the increasing of gripper loom reed space.

Description

technical field [0001] The invention relates to a weft insertion mechanism of a rapier loom, in particular to a reed width increasing device for the weft insertion mechanism of a rapier loom. The invention belongs to the technical field of looms of textile machinery. Background technique [0002] In the prior art, in order to adapt to the requirements of the reed width from narrow width to wide width on the rapier loom, the usual practice is to install the end element of the weft insertion mechanism - the sector gear 1 and the shaft gear 7 coaxial with the sword wheel. To adjust the number of teeth (as shown in Figures 1 and 2), is to increase the number of teeth of the sector gear, reduce the number of teeth of the shaft gear coaxial with the sword wheel, increase the rotation angle of the sword wheel, and increase the movement stroke of the sword belt. Due to the limited adjustment range of the number of gear teeth, the reed width of existing rapier looms is limited, gene...
