Description

Technical Field

[0001] The present application relates to the technical field of jacquard machines, and in particular to a driving structure of a jacquard machine. Background Art

[0002] Conventional jacquard machines do not have a separate drive motor. The power of the entire mechanical system comes from the loom, and the power of the loom is input to the jacquard machine through mechanical connections such as right-angle gearboxes, drive shafts, and connectors. As customers currently have higher and higher requirements for the fineness of fabrics, especially for the weaving of ultra-high warp density fabrics, the power looms required by jacquard machines can no longer meet the needs; or when two jacquard machines are installed in parallel on one loom, the loom can only meet the power requirements of one jacquard machine, and the other jacquard machine needs an additional power source. In order to solve this problem, it is necessary to provide power to the jacquard machine separately.

[0003] Since the speed of the servo motor is too high (1500-2000rpm, the speed required for jacquard is about 200rpm), the conventional practice is to use a planetary gear reducer or a homemade reducer. For example, the patent with the publication number CN112899847A discloses a power transmission and reduction mechanism of a servo motor direct-driven jacquard machine, which is installed between the jacquard machine and the servo motor through a reduction structure to achieve motor reduction and torque increase. The reducer is composed of a multi-stage gear combination, and there is a gear gap, which will also cause vibration and noise during operation. Conventional motor and reducer solutions all use shaft-to-shaft connection, resulting in a longer equipment length and higher manufacturing and transportation costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, one of the purposes of the present application is to provide a jacquard machine driving structure, which has the advantages of low manufacturing and transportation costs.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0006] A jacquard machine driving structure comprises a frame, the frame is provided with a wall panel, the wall panels are two and arranged oppositely, the frame is provided with a low-speed motor, and the low-speed motor is arranged between the two wall panels.

[0007] By adopting the above technical solution, during use, since the low-speed motor is arranged between the two wall panels, it occupies less space and has lower transportation costs. In addition, the torque of the low-speed motor is larger and no reducer is required, so the manufacturing cost is lower.

[0008] In a preferred example, the present application can be further configured as follows: the low-speed motor includes a rotor, and both ends of the rotor correspond to and are connected to the main transmission shafts on both sides one by one.

[0009] By adopting the above technical solution, the rotor is connected to the main transmission shafts on both sides, so that the kinetic energy loss of the transmission chain can be reduced and the noise can be reduced.

[0010] In a preferred example, the present application can be further configured as follows: the rotor is hollow, and the main transmission shaft passes through the rotor and is connected to the rotor.

[0011] By adopting the above technical solution, the connection between the main transmission shaft and the motor is made more convenient.

[0012] In a preferred example, the present application can be further configured as follows: the spacing between the wall panels on both sides of the low-speed motor is equal.

[0013] By adopting the above technical solution, since the distance between the axis of the rotor and the wall plates on both sides is equal, the forces on both sides of the main transmission shaft are consistent or basically the same, and the elastic torsional deformation of the main transmission shaft is consistent or basically the same.

[0014] In a preferred example, the present application can be further configured as follows: a detection component for detecting the rotation speed is provided on the frame.

[0015] By adopting the above technical solution, the existence of the detection member makes it possible to detect the rotation speed of the main transmission shaft, so that it can be adapted to the loom speed.

[0016] In a preferred example, the present application can be further configured as follows: the detection element is an encoder.

[0017] In a preferred example, the present application can be further configured as follows: the encoder and the main transmission shaft are coaxially connected.

[0018] By adopting the above technical solution, the encoder is coaxially connected to the main transmission shaft with high precision, and the rotation speed of the jacquard machine is matched with the loom in real time to ensure synchronous operation of the equipment.

[0021] The present application is further described in detail below in conjunction with the accompanying drawings.

[0022] Reference Figure 1, is a jacquard machine driving structure disclosed in the present application, including a frame 1, a wall panel 2 is provided on the frame 1, the wall panels 2 have two and are arranged opposite to each other, a mounting frame 3 is provided on the frame 1, and is used to install a low-speed motor. In this embodiment, the low-speed motor adopts a permanent magnet high-torque motor, which has the characteristics of low speed and high torque, and other motors with the above characteristics can also be used. The low-speed motor includes a rotor, and the low-speed motor is at an equal distance from the two wall panels 2. More specifically, the center of the rotor is at an equal distance from the wall panels 2 on both sides.

[0023] The rotor is hollow, and the main transmission shaft 4 passes through the rotor and is fixedly connected to the rotor. The frame 1 is also provided with a detection member 5 for detecting the rotation speed of the main transmission shaft 4. The detection member 5 is an encoder, and the encoder and the main transmission shaft 4 are coaxially connected.

[0024] The main transmission shaft 4 is rotatably connected to the wall panel 2, and driving wheels 6 are fixedly connected to both ends of the main transmission shaft 4. Both wall panels 2 are rotatably connected to transmission wheels 7. The driving wheel 6 on the main transmission shaft 4 and the transmission wheel 7 on the corresponding wall panel 2 are driven by a chain. Two groups of lifting knives of the jacquard machine are respectively hung on both sides of the transmission wheel 7. The rotation of the transmission wheel 7 drives the two groups of lifting knives to reciprocate in a straight line, thereby driving the needle selection component to work to form an opening.

[0025] The implementation principle of this embodiment is: by fixing the low-speed motor on the frame 1 and locating it in the middle position of the two wall panels 2, the low-speed motor drives the main transmission shaft 4 to rotate, and the main transmission shaft 4 drives the transmission wheel 7 to rotate, and the transmission wheel 7 drives the knife lifting work.

[0026] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
