Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] combine Figure 1 to Figure 8 As shown, a weft insertion transmission mechanism includes a camshaft 1 on which an eccentric block 13 is arranged, and the weft insertion transmission mechanism also includes a transmission arm 5 , a special-shaped bearing 6 and a swing box 2 . One end of the transmission arm 5 is connected to the eccentric block 13 on the camshaft 1, and the other end of the transmission arm 5 is connected to the special-shaped bearing 6 through the gland 7. The central axis d1 of the transmission arm intersects the central axis a of the camshaft and forms a shape less than 90 degrees angle α. The outer ring surface of the special-shaped bearing 6 is provided with two connecting shafts 61, the two connecting shafts 61 are arranged obliquely relative to the center of the special-shaped bearing 6, the central axes c of the two conne...

The invention relates to a wefting insertion transmission mechanism for a rapier loom. The wefting insertion transmission mechanism comprises a cam shaft, a transmission arm, a special-shape bearing and a swing box, wherein an eccentric block is arranged on the cam shaft, one end of the transmission arm is connected with the eccentric block on the cam shaft, and the other end of the transmission arm is connected with the special-shape bearing through a gland; two connection shafts are arranged on the outer ring surface of the special-shape bearing and inclined relative to the center of the special-shape bearing; the swing box is in an annular shape, and a positioning shaft is arranged at the periphery of the swing box; and the special-shape bearing is arranged in the swing box and is in running fit with the swing box through the two connection shafts. The eccentric block on the cam shaft of the wefting insertion transmission mechanism is connected with the special-shape bearing through the transmission arm, the transmission arm is inclined relative to the eccentric block, the special-shape bearing is arranged in the swing box and is in running fit with the transmission arm and the swing box at two different angles respectively, and thus the cam shaft converts a circular motion into front-back swing conforming to the motion law of a rapier transmission wheel in a short distance.
Description
technical field [0001] The invention relates to the technical field of textile machinery, in particular to a weft insertion transmission mechanism for a rapier loom. Background technique [0002] Chinese Patent No. CN85104954 disclosed on January 7, 1987 a mechanism for controlling the movement of the weft insertion rapier in a shuttleless loom. The front and rear rotation of a large gear that controls the rapier belt is generated by a variable pitch cam screw. The screw rod is axially intersected with a sliding piece that moves back and forth along a constrained linear track, and the sliding piece is equipped with a device that engages with the screw teeth of the screw rod and makes it rotate, and the device includes several pairs of opposite sliding blocks. The mechanism for controlling the movement of the weft insertion rapier is complex in structure, bulky, and not easy to install; moreover, the friction between the various parts is severe, resulting in increased noise a...
