Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-6 shown, a transmission mechanism of a thread rack pushing device of a textile machine includes a main shaft 1, an active synchronous pulley 2 is sleeved on the main shaft 1, the active synchronous pulley 2 is connected with a driven synchronous pulley 21 through a belt, a driven shaft 3 passes through the driven synchronous pulley 21, an eccentric sleeve 4 is arranged on the driven shaft 3, the eccentric sleeve 4 is connected with a first connecting rod 5, the first connecting rod 5 is connected with a first joint 51, and further includes a rocker arm plate 6 connected with the thread rack pushing device, the rocker arm plate 6 is rotatably arranged on a mounting bracket 61, and the first joint 51 is rotatably connected with the rocker arm plate 6; an eccentric sleeve 4 is also arranged on the main shaft 1, the eccentric sleeve 4 is connected with a second connecting rod 7, the second connecting rod 7 is connected with a second joint 71, and the second joint 71 is directly rotatably connected with the thread rack pushing device; a driven pulley 8 is further arranged on the main shaft 1, the driven pulley 8 is connected with a driving pulley 81 through a belt, and the driving pulley 81 is connected with a gearbox 82; the main shaft 1 is connected with a manual wheel 9 through a bevel gear structure 91.

[0025] By adopting the above technical solutions, in the present utility model, the main shaft 1 can be manually rotated through the manual wheel 9 or electrically rotated through a motor. Among them, the eccentric sleeve 4, the second connecting rod 7 and the second joint 71 arranged on the main shaft 1 can realize the swinging of the thread rack pushing device, and the reciprocating translational movement of the thread rack pushing device can be realized through the eccentric sleeve 4, the first connecting rod 5, the first joint 51 and the rocker arm plate 6 arranged on the driven shaft 3. Moreover, by arranging the active synchronous pulley 2 and the driven synchronous pulley 21, specifically, the diameter of the driven synchronous pulley 21 is larger than that of the active synchronous pulley 2, so that the driven shaft 3 can rotate at a reduced speed relative to the main shaft 1, and the translational movement of the thread rack pushing device can be decelerated, so that the change of the textile pattern can be realized.

[0026] As a specific embodiment of the improvement, the eccentric sleeve 4 includes an eccentric core sleeve 41 eccentrically sleeved on the driven shaft 3, an eccentric outer sleeve 42 sleeved outside the eccentric core sleeve 41, and a bearing sleeve 43 located between the eccentric core sleeve 41 and the eccentric outer sleeve 42.

Bearing seats 31 are provided on both sides of the driven shaft 3 where the eccentric sleeve 4 is located.

[0027] By adopting the above technical solution, since the eccentric core sleeve 41 is eccentrically arranged on the driven shaft 3, the eccentric sleeve 4 can drive the first connecting rod 5 to move up and down. Among them, the eccentric core sleeve 41 is set as a split positioning core sleeve 44 and a fastening core sleeve 45. During installation, first install the positioning core sleeve 44 on the driven shaft 3, and then fasten the fastening core sleeve 45 to the positioning core sleeve 44 through fasteners such as screws, so as to achieve the connection stability between the positioning core sleeve 44 and the driven shaft 3. And by providing the bearing sleeve 43, the rotational friction of the eccentric outer sleeve 42 is reduced, making the transmission efficiency higher. The setting of the positioning ring groove 46 on the positioning core sleeve 44 is to realize the positioning installation of the bearing sleeve 43, and the fastening clamp 48 is installed in the positioning groove 47. The setting of the fastening clamp 48 is to firmly position the bearing sleeve 43 on the positioning core sleeve 44.
