Embodiment 1

[0020] 3 and 4, the present invention is a space crank rocker weft insertion mechanism for a rapier loom, which is mainly composed of a main shaft 1, a crank rocker mechanism, a gear pair 11, a shaft gear 10 and a sword transmission wheel 12. . The crank-rocker mechanism is mainly composed of a crank 2 , a cradle 3 , a swinging body 8 and a sector gear 9 . The end face of the crank 2 is spherical, the middle of the crank 2 is connected to one end of the main shaft 1, the shaft end of the cradle 3 is connected to the crank 2 through the rolling bearing 4, the slider 5 and the screw 6, and the two shaft ends of the swing body 8 are connected to the cradle through the rolling bearing 7. 3 is connected, the swing body 8 is fixed with a sector gear 9, the sector gear 9 meshes with the shaft gear 10, or meshes with the shaft gear 10 through the gear pair 11, the shaft gear 10 is coaxial with the sword transmission wheel 12, and the sword transmission wheel 12 is The drive parts of ...

Embodiment 2

[0025] 5 and 6, the difference between this embodiment and Embodiment 1 is that a groove is provided in the crank 2, the slider is fixedly connected in the groove with a screw 6, and the rolling bearing 4 is embedded in the slider.

Abstract

The invention involves a space crank rocker weft insertion device used for gripper loom, it includes: spindle (1), axle gear (10) and the gripper-transmitting wheel(12), the axle gear and the gripper-transmitting wheel are coaxial, the spindle is connected with a crank rocker device, the crank rocker device includes crank (2), cradle (3), pendular body (8) and fan gear (9), the crank is fixed with the spindle, axle end of cradle is connected with the crank through rolling bearing (4) and slide blocks (5), two axle ends of pendular body is connected with cradle through rolling bearing (7), the pendular body is fixed and equipped with fan gear, the fan gear is engaged with the axle gear directly, or the fan gear first is engaged with gear pair (11), then the gear pair is engaged with axle gear, the central axial trace (AA') of spindle, the rotary axial trace (EE') of cradle, the central axial trace (CC') of pendular body and the swinging centre of fan gear are intersected at same crossing point (O) in space, a included angle ( alpha ) which is bigger than zero degree is left between said rotary axial trace (EE') of cradle and central axle of spindle. The invention can adjust the stroke of gripper belt conveniently, the structure is simple and compact, and the movement is stable and reliable.

Description

technical field [0001] The invention relates to a rapier loom, in particular to a space crank rocker weft insertion mechanism for the rapier loom. It belongs to the technical field of looms of textile machinery. Background technique [0002] In the prior art, the weft insertion process of the rapier loom consists of two rapier heads that move relatively reciprocatingly along the reed width direction of the loom, and start to move from the two sides of the loom to the center of the shed of the loom. Weft yarn, and then back to the starting position on both sides, thus completing a weft insertion. Among them, the sword head is driven by the sword belt, and the sword belt is driven by the teeth on the sword transmission wheel meshing with the perforations on the sword belt, or the end of the smooth sword belt is fixed on the sword transmission wheel and driven by the sword transmission wheel. The key to the weft insertion mechanism of the rapier loom is that the uniform rotat...
