[0002] A jacquard machine is a textile machine used to weave jacquard fabrics. It can control the rise and fall of the warp threads through a complex mechanical structure to form exquisite patterns and designs on the fabric. Jacquard machines are mainly used to weave fabrics with complex patterns, such as silk, brocade, and decorative fabrics. It controls the rise and fall of the warp threads and interweaves them with the weft threads to form various patterns. It is widely used in clothing, home textiles, handicrafts and other fields.

The axis of the connecting shaft 34 is fixedly connected to a rotating column 35 rotatably connected to the diversion tube 18.

[0030] It should be noted that: the positioning column 49 enables the sealing ring 36 to fit tightly against the end of the air duct 19, thereby improving the sealing of the air duct 19, so that after the wind is generated, it can only enter the air duct 19 through the air hole 37.

[0031] In the embodiment of the present invention, please refer to Figure 2 and Figure 3 The elastic member 5 shown in the figure includes a sliding block 50 sleeved on the outer side of the rotating shaft 7, the sliding block 50 is slidably connected to the support plate 2, and a second spring 51 is fixedly connected to the sliding block 50, and the end of the second spring 51 is fixedly connected to a support plate 52 fixedly connected to the support plate 2.

[0032] It should be noted that the design of the second spring can make the tensioning roller swing up and down, and then the tension of the wire harness can be dynamically adjusted through the action of the second spring 51, thereby improving the smoothness of the wire harness transportation.

[0033] Working principle: The wire harness of the jacquard machine passes through the bottom end of the positioning roller 3, then is wound around the end of the tensioning roller 4, and then passes through another set of positioning rollers 3 to the needle threading position of the jacquard machine. In this solution, each set of tensioning blocks 12 is provided with a number of wire harness grooves, which limit the wire harness. When adjusting the tension, the first motor 32 is controlled to start. After the first motor 32 is started, the rotating frame 33 is driven to rotate, and the wind wheel 28 is driven to rotate by the rotation of the rotating frame 33. The rotation of the wind wheel 28 generates wind power, which is transported to the docking pipe 29 through the wind hood 26, and then transported to the connecting pipe 24 through the docking pipe 29. The wind power is then transported to the diversion pipe 18 through the connecting pipe 24. When the wind power enters the diversion pipe 18, at this time, the wind will enter the air delivery pipe 19 connected to the air delivery hole 37, and then the air delivery pipe 19 will deliver the wind to the inside of the air inlet pipe 20, and then pass through the connecting cover 10 and the air inlet hole 22 to allow the wind to enter the air inlet pipe 8, and then deliver the wind to the air delivery pipe 9 through the air inlet pipe 8, and deliver the wind to the inside of the multiple sets of sleeves 14 through the air delivery pipe 9, thereby increasing the air pressure inside the sleeves 14, and the moving block 15 is moved by the action of the air pressure, and the movement of the moving block 15 will drive the moving rod 16 to move, and then the movement of the moving rod 16 causes the multiple sets of tensioning blocks 12 to move outward at the same time, and the movement of the tensioning block 12 increases the tension of the wiring harness wound around the outer side of the tensioning block 12; When the tensioning force needs to be reduced, the first motor 32 is controlled to rotate in the reverse direction. The reverse rotation of the first motor 32 generates suction inside the docking tube 29. At this time, suction is also generated inside the docking tube 29. The action of the suction causes the moving block 15 to drive the moving rod 16 to move in the opposite direction, thereby causing the multiple sets of tensioning blocks 12 to move closer to the axis at the same time, thereby reducing the tension of the wiring harness. Furthermore, after one set of tensioning blocks 12 is adjusted, the second motor 41 is started. After the second motor 41 is started, the drive shaft 42 is driven to rotate. The rotation of the drive shaft 42 drives the rotating column 35 to rotate, and then drives the connecting shaft 34 to rotate. The rotation of the connecting shaft 34 drives the sealing ring 36 to rotate. The rotation of the sealing ring 36 switches the position of the air delivery hole 37, and then adjusts the position of the other set of tensioning blocks 12, thereby adjusting the tension of the other set of wiring harnesses. After the position of the air delivery hole 37 is determined, the motor is controlled to rotate forward or reverse according to the required tension of the wiring harness. After the motor rotates forward, the wind wheel 2 8 generates wind force when it rotates forward, and then the wind force is blown into the inside of the sleeve 14, so that the moving block 15 drives the moving rod 16 to move, and then the tensioning block 12 moves outward, thereby increasing the tension. When the motor is controlled to reverse, the wind wheel 28 reverses to generate suction inside the sleeve 14, thereby causing the moving block 15 and the moving rod 16 to move in opposite directions, and then the tensioning block 12 moves closer to the axis. At this time, the tension is reduced. Through the rotation of the second motor 41, the air delivery hole 37 is connected to different air delivery pipes 19 in sequence, thereby controlling the tension of different tensioning blocks 12, and then separately controlling and adjusting the wiring harnesses wound around the outer sides of different tensioning blocks 12; It should be noted that the rotation of the rotating column 35 drives the rotating block 43 to rotate, and the rotation of the rotating block 43 causes the ball 47 to rotate. During the rotation of the ball 47, the action of the first spring 45 enables the ball 47 to correspond to different rolling grooves 48 in sequence. The action of the ball 47 and the rolling groove 48 can limit the position of the rotating block 43, and then limit the position of the rotating column 35, thereby ensuring the stability of the connecting shaft 34 and the sealing ring 36. In addition, multiple sets of positioning posts 49 are provided on the outside of the sealing ring 36. Through the action of the multiple sets of positioning posts 49, the sealing ring 36 can be closely fitted to the top end of the shunt pipe 18, thereby ensuring that the sealing ring 36 can seal the air duct 19 other than the air duct 19 connected to the air duct hole 37, and ensure that the multiple sets of different tensioning blocks 12 linearly distributed on the prismatic column 6 can be controlled and adjusted separately; It is also worth noting that a sliding block 50 is provided on the outer side of the rotating shaft 7, and the sliding block 50 is connected to the support plate 2 through a second spring 51 and a support plate 52. Therefore, during the jacquard process, the rotating shaft 7 will swing up and down due to the pulling of the wire harness, and the tension of the wire harness can be dynamically adjusted through the action of the second spring 51, thereby improving the smoothness of the wire harness transportation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
