Weft inserting mechanism of sample loom

Abstract

The invention relates to a weft inserting mechanism of a sample loom, which is used for introducing weft yarn into a warp yarn weaving port for filling warp blends to form a cloth sample. The weft inserting mechanism comprises a rapier head (1), a rapier (4), a guide wheel (3), a rapier seat (5), a guide wheel support seat (2), a rigid support seat (9), a linear bearing sliding block (11), a linear guide rail (12), a cantilever bracket (13), a right wall board (10), a servo motor (6), a synchronous belt pulley I (7), a synchronous belt pulley support seat (14), a synchronous belt pulley II (15) and a synchronous belt (8), wherein two ends of the rapier (4) are fixed to the rapier seat (5) by the guide wheel (3); the rapier seat (5) is arranged on the linear bearing sliding block (11); the linear guide rail (12) is arranged on the cantilever bracket (13); one end of the cantilever bracket (13) is arranged on the rigid support seat (9); the synchronous belt pulley I (7) is arranged on an output shaft of the servo motor (6); the synchronous belt pulley support seat (14) and the synchronous belt pulley II (15) are arranged at the other end of the cantilever bracket (13); and the synchronous belt (8) is connected with the rapier seat (5). The invention improves the weaving speed, simultaneously avoids the use of compressed air and solves the problems that an air cylinder is easy to damage and the cloth cover is polluted.

Description

(1) Technical field [0001] The invention relates to a sample loom, in particular to a weft insertion mechanism of the sample loom. It is used to introduce the weft yarn into the warp yarn mouth, and weave the sample fabric through the interweaving of the warp and weft yarns. It belongs to the technical field of textile machinery. (2) Background technology [0002] The weft insertion mechanism is one of the five key mechanisms of the sample loom. Through this mechanism, the weft yarn is introduced into the warp yarn mouth, and the warp and weft are interwoven to form a cloth pattern. At present, due to the short width and slow speed of the sample looms, most of them adopt the cylinder weft insertion mechanism. The rapier head is installed at the front end of the piston rod of the cylinder, and the piston rod of the cylinder is stretched and contracted by the reversing of the solenoid valve, so as to achieve the purpose of weft insertion. . In actual use, the cylinder weft...
