Description

Technical Field

[0001] The utility model relates to the technical field of jacquard shedding devices, and particularly relates to a servo-driven jacquard shedding device. Background Art

[0002] As an essential device for rapier looms and air-jet looms and other textile machines to complete jacquard weaving, the electronic jacquard head has a gradually increasing market retention in China, and there are various types of jacquard shedding mechanisms produced by domestic jacquard machine manufacturers. In the prior art, there are many transmission components and many transmission links in the jacquard shedding mechanism: during the mechanical operation process, due to too many transmission links, individual components may fail, which in turn affects the stability of the entire transmission system.

[0003] Based on this, a prior application with a publication number of CN220520746U by the applicant of the present application discloses a servo-driven jacquard shedding device, including a first swing arm, a second swing arm, a first inner and outer knife rest, a second inner and outer knife rest, a first servo motor, a second servo motor, a first transmission shaft, a second transmission shaft, and a jacquard machine main body. The first servo motor and the second servo motor are fixed on both sides of the jacquard machine main body, and the first servo motor is connected to one end of the first transmission shaft, and the second servo motor is connected to one end of the second transmission shaft. The first servo motor and the second servo motor share a servo driver or are configured with independent servo drivers, and the first servo motor and the second servo motor respectively drive the second swing arm and the first swing arm to perform synchronous relative swinging within a set angle. It adopts an independent servo drive mechanism or shares a servo driver, which can remove multiple intermediate transmission components, reduce many transmission links, and reduce the situation that individual components fail due to too many transmission links during the mechanical operation process, thereby affecting the stability of the entire transmission system. Since this servo-driven jacquard shedding device requires two servo motors to control two transmission shafts respectively, and then drive two swing arms to perform synchronous relative swinging within a set angle. However, an independent servo drive mechanism or a shared servo driver is needed to set the driving of the two motors. If a driver fails, resulting in a deviation in the swing arm amplitude, it will affect the weaving quality; and the costs of the two motors (the cost of the motors themselves and the energy consumption costs of the motors) are relatively high, and the subsequent maintenance and replacement costs are also relatively high. Content of the Utility Model

[0004] The utility model aims to solve some problems existing in the prior art. For this purpose, an object of the utility model is to propose a servo-driven jacquard shedding device that uses one motor, and this motor drives two transmission shafts to rotate through two meshing gears, and then completes the weaving work.

[0005] To achieve the above object, the utility model proposes:

[0006] A servo-driven jacquard shedding device, comprising a jacquard machine main body, wherein a motor, a first gear, a second gear, a first transmission shaft and a second transmission shaft are arranged on the jacquard machine main body. The motor is installed on one side of the top of the jacquard machine main body. One end of the output shaft of the motor is connected to the first gear. The first gear is connected to the first transmission shaft. The first gear meshes with the second gear. The second gear is connected to the second transmission shaft. A first swing arm assembly is installed on the first transmission shaft. A first tool rest is installed at the other end of the first swing arm assembly. A second swing arm assembly is installed on the second transmission shaft. A second tool rest is installed at the other end of the second swing arm assembly.

[0007] Preferably, a draw knife is arranged on the first tool rest and the second tool rest.

[0009] Preferably, the first swing arm assembly is located inside the second swing arm assembly.

[0010] The beneficial effects of the present utility model:

[0011] The present utility model uses a servo motor to drive the first transmission shaft to swing within a certain angle range. The first transmission shaft simultaneously drives the second transmission shaft to rotate in the opposite direction through two meshing gears. Under the action of the swing arm assembly, two tool rests are driven to move up and down reciprocally, and the two tool rests keep running synchronously in the opposite direction to complete the weaving process. Only one communication drive program needs to be set, and the cost investment can be reduced.

[0018] Please refer specifically to Figure 1 , a servo-driven jacquard shedding device, comprising a jacquard machine main body 100, on which a motor 1, a first gear 2, a second gear 3, a first transmission shaft 4 and a second transmission shaft 5 are arranged. The motor 1 is installed on one side of the top of the jacquard machine main body 100, one end of the output shaft of the motor 1 is coupled to the first gear 2, the first gear 2 is coupled to the first transmission shaft 4, the first gear 2 meshes with the second gear 3, the second gear 3 is coupled to the second transmission shaft 5, a first swing arm assembly 6 is installed on the first transmission shaft 4, a first knife rest 8 is installed at the other end of the first swing arm assembly 6, a second swing arm assembly 7 is installed on the second transmission shaft 5, a second knife rest 9 is installed at the other end of the second swing arm assembly 7, and a pulling knife is arranged on the first knife rest 8 and the second knife rest 9 for textile manufacturing.

[0019] As an improvement of the present utility model, the servo-driven jacquard shedding device adopts a gear transmission method to replace the original dual-motor 1 drive method. The output shaft of the motor 1 rotates to drive the first gear 2 and the first transmission shaft 4 to rotate, thereby driving the first swing arm assembly 6 to swing. Under the principle of gear meshing, the second gear 3 and the second transmission shaft 5 will rotate in the opposite direction, thereby driving the second swing arm assembly 7 to swing in the opposite direction, and at the same time driving two sets of knife rests to perform reciprocating up and down movements. The two sets of knife rests maintain synchronous operation in opposite directions to complete the weaving process. Compared with the previous dual-motor 1 drive method, the cost investment can be reduced. Only one control drive program needs to be set, and there will be no situation where the quality of the product is affected due to the failure of one driver. Since the number of electrical equipment is reduced, the maintenance difficulty can also be reduced.

[0020] In this embodiment, the motor 1 is a servo motor 1, configured with a servo driver, which can receive a communication drive program to control the operation of the motor 1.

[0021] Further, the number of the first swing arm assembly 6 and the second swing arm assembly 7 is two groups each, and they are respectively located on both sides of the jacquard machine main body 100. Specifically, each group of the first swing arm assembly 6 and the second swing arm assembly 7 is composed of a connecting plate and a swing arm. The connecting plates of the first swing arm assembly 6 and the second swing arm assembly 7 are respectively connected to the first transmission shaft 4 and the second transmission shaft 5. One end of the swing arm of the first swing arm assembly 6 is movably hinged to the connecting plate of the first swing arm assembly 6, and the other end is movably hinged to the first knife rest 8. One end of the swing arm of the second swing arm assembly 7 is movably hinged to the connecting plate of the second swing arm assembly 7, and the other end is movably hinged to the second knife rest 9.

[0022] Further, the first swing arm assembly 6 is located inside the second swing arm assembly 7.

[0023] The working principle of a servo-driven jacquard shedding device of the present utility model is described in conjunction with the accompanying drawings:

[0024] The present utility model is a set of motor 1, cooperating with two meshing gears, controlling the rotation of two transmission shafts, and ensuring synchronous movement. Specifically, the output shaft of the motor 1 rotates to drive the first gear 2 and the first transmission shaft 4 to perform reciprocating clockwise and counterclockwise rotations within a certain angle, thereby driving the first swing arm assembly 6 to perform corresponding swings within a certain angle. At the same time, the second gear 3 and the second transmission shaft 5 will rotate in the opposite direction, thereby driving the second swing arm assembly 7 to perform corresponding swings in the opposite direction within a certain angle, and at the same time driving two sets of knife rests to perform reciprocating up and down movements. The two sets of knife rests maintain synchronous operation in opposite directions to complete the weaving process.
