Description

Technical Field

[0001] The present application relates to the technical field of jacquard machines, and in particular to a direct-drive structure of a jacquard machine with a large number of needles. Background Art

[0002] At present, in the jacquard weaving industry, the number of needles per jacquard machine is limited by insufficient driving force and material deformation, and the upper limit of the number of needles per machine is about 30,000, which cannot be increased indefinitely. For example, in order to obtain a jacquard opening of 40,000 needles on a loom, the conventional practice is to install two 20,000-needle jacquard machines side by side on top of a loom. The disadvantage of this is that the integration of the two devices is not high and the volume is larger. Utility Model Content

[0003] In view of the shortcomings of the prior art, one of the purposes of the present application is to provide a direct-drive structure for a large-needle-count jacquard machine, which has the advantages of high integration and smaller size.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] A direct drive structure of a large needle number jacquard machine comprises a frame, the frame is provided with a wall panel, the wall panels are two, the frame is also provided with a driving motor, the driving motors are two and correspond to the two wall panels one by one, and the driving motor is located on one side of the corresponding wall panel.

[0006] By adopting the above technical solution, by installing two drive motors on a jacquard machine with a large number of needles and driving it through two drive motors, the integration level can be effectively improved. At the same time, compared with the method of connecting multiple motors in parallel, the volume is smaller, and the two motors can also provide sufficient torque to solve the problem of insufficient motor driving force.

[0007] In a preferred example, the present application can be further configured as follows: the distance between the driving motor and the wall panel is no more than 300 mm.

[0008] By adopting the above technical solution, the distance between the motor and the wall panel is small, so the distance between the motor and the transmission wheel installed on the wall panel is small, so the influence of the torsional elastic deformation of the transmission shaft on the transmission wheel is reduced.

[0009] In a preferred example, the present application can be further configured as follows: a transmission shaft is installed on the rotor of one driving motor, and the transmission shaft extends to the rotor of another driving motor and is fixedly connected to the rotor.

[0010] By adopting the above technical solution, the two motors jointly provide power, so that the degree of synchronization is better.

[0011] In a preferred example, the present application can be further configured as follows: the driving motor is arranged on a side of the corresponding wall panel away from the other wall panel.

[0012] By adopting the above technical solution, the distance between the two motors is relatively large, and the elastic torsional deformation of the transmission shaft can buffer the angular difference between the two motors.

[0013] In a preferred example, the present application can be further configured as follows: it also includes a speed measuring component, and the speed measuring component is used to detect the rotation speed of the transmission shaft.

[0014] By adopting the above technical solution, the existence of the speed measuring component makes it possible to monitor the rotation speed.

[0015] In a preferred example, the present application can be further configured as follows: there are two speed measuring parts corresponding to the two ends of the transmission shaft.

[0016] By adopting the above technical solution, the rotation speeds at both ends of the transmission shaft are detected, thereby further reducing the probability of production problems caused by excessive angle differences caused by the drive motor. At the same time, the rotation speed of the jacquard machine is matched with the loom in real time to ensure synchronous operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, the drive motors 3 are permanent magnet high torque motors. The two drive motors 3 correspond to the two wall panels 2. The drive motors 3 are arranged on the outside of the wall panels 2. The distance between the drive motors 3 and the wall panels 2 is not more than 300 mm, and is 300 mm in this embodiment.

[0021] Both ends of the transmission shaft 4 pass through the corresponding wall panels 2 and are rotatably connected to the wall panels 2. A driving wheel for shaking the transmission wheel is installed on the transmission shaft 4. The rotor of the driving motor 3 located on both sides of the wall panels 2 is fixedly connected to the transmission shaft 4. A speed measuring part 5 is also provided on the frame 1. In this embodiment, the speed measuring part 5 is a rotary encoder, and the speed measuring part has two speed measuring parts for detecting the rotation speed of the two ends of the transmission shaft 4.

[0022] The implementation principle of this embodiment is: in use, the transmission shaft 4 is driven to rotate by two driving motors 3, and the driving wheel is driven to rotate by the transmission shaft 4, and the transmission wheel is driven to rotate by the driving wheel. Since the distance between the motor and the transmission wheel is small, the influence of the elastic torsional deformation of the transmission shaft 4 on the operation can be effectively reduced.

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.
