[0023] The present application is further described in detail below in conjunction with the accompanying drawings.
[0024] Reference Figure 1-Figure 3, is a jacquard machine disclosed in the present application, comprising a frame 1, on which a motor and a transmission mechanism are provided, the transmission mechanism comprising a main transmission shaft 2 and a swing assembly 3. In the present embodiment, the motor is a servo motor, which is mounted on the frame 1, the main transmission shaft 2 is rotatably connected to the frame 1, and is arranged in the middle position of the frame 1, and the motor is used to drive the main transmission shaft 2 to rotate.
[0025] There are two groups of swing assemblies 3, which are respectively arranged on both sides of the main transmission shaft 2. The swing assembly 3 includes a transmission arm 31, a swing arm 32, a swing shaft 33, a pull rod 35 and a connecting arm 34. One end of the transmission arm 31 is eccentrically connected to the main transmission shaft 2, and the other end is hinged to the swing arm 32. The swing shaft 33 is rotatably connected to the frame 1, and the swing arm 32 is connected to the swing shaft 33 to drive the swing shaft 33 to rotate. There are multiple pull rods 35 and connecting arms 34, and the connecting arms 34 and pull rods 35 correspond to each other. The connecting arm 34 is fixedly connected to the swing shaft 33. The pull rod 35 is provided with a secondary arm 351, and there are two secondary arms 351 that are arranged opposite to each other. The connecting arm 34 is provided with a connecting groove 341, and the secondary arms 351 are located on both sides of the connecting groove 341 and are connected to the connecting arm 34 through a connecting rod passing through the connecting groove 341. The spacing between the pull rod 35 and the swing shaft 33 gradually decreases along the axis of the swing shaft 33, that is, the connection point between the pull rod 35 and the connecting arm 34 gradually approaches the swing shaft 33. In this embodiment, the connecting rod is a bolt. The connecting arm 34 is provided with multiple limiting concave surfaces 342, and the spacing between adjacent limiting concave surfaces 342 is equal. The corresponding pull rods 35 located on both sides of the main transmission shaft 2 are connected with a broach.
[0026] The implementation principle of this embodiment is: the motor drives the main transmission shaft 2 to rotate, and the rotation of the main transmission shaft 2 drives the transmission arm 31 to swing, thereby causing the swing arm to swing. During the swinging of the swing arm, the connecting arm 34 swings, thereby driving the pull rod 35 to move up and down, thereby driving the broach to move up and down.
