[0016] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] Please see Figure 1-8 The present invention provides a technical solution: Automatic calibration device for electronic jacquard machines, including Transmission device 2 is located on one side of mounting plate 1. Transmission device 2 includes a first chain 21 and a transmission seat 22. The first chain 21 is driven to rotate by a motor. The transmission seat 22 is driven to rotate by the first chain 21. A lifting rod 23 is provided on one side of the transmission seat 22. The rotation of the transmission seat 22 drives the lifting rod 23 to move up and down. The swing seat 3 is located at the bottom of the lifting rod 23. The swing seat 3 includes a mounting seat 31, a cylinder 32 is provided at the top of the mounting seat 31, an adjusting seat 35 is provided at the bottom of the mounting seat 31, a driving mechanism 33 is provided on one side of the adjusting seat 35, and the output end of the cylinder 32 is fixedly connected to the top of the adjusting seat 35. The connecting beam 4 is located inside the adjusting seat 35. The connecting beam 4 includes a housing 41. The inner cavity of the housing 41 is movably connected to a rotating shaft 42. The two ends of the rotating shaft 42 are provided with a fourth gear 46. The housing 41 contains a second motor 44. The output end of the second motor 44 is provided with a third gear 45. The bottom outer edge of the third gear 45 is meshed with a second gear 43. The second gear 43 is fixed to the outside of the rotating shaft 42. Control seats 34 are located in the inner cavity of adjustment seats 35, and there are at least two of them. A lifting knife 5 is provided at the bottom of the control seats 34. The control seats 34 include a fixed seat 341. A swing plate 342 is movably connected to the inner cavity of the fixed seat 341. The angle of the swing plate 342 is adjusted by driving the drive mechanism 33. A rack 346 is provided at the top of the fixed seat 341. The top of the rack 346 meshes with the outer edge of the fourth gear 46.

[0018] In this embodiment, please refer to Figure 3-4 The transmission seat 22 includes a transmission plate 221 and a first sprocket 222. The outer side of the first sprocket 222 meshes with the inner wall of the first chain 21. Multiple electromagnetic seats 224 are arranged on one side of the transmission plate 221, and the distances between the center points of the multiple electromagnetic seats 224 and the transmission plate 221 are all different. The lifting rod 23 includes an outer sleeve rod 231, and a metal column 232 is arranged on one side of the outer sleeve rod 231. When the electromagnetic seats 224 are energized, the metal column 232 attracts the electromagnetic seats 224. An inner sleeve rod 233 is movably connected to the inner cavity of the outer sleeve rod 231. The swing seat 3 has a drive mechanism inside for driving the outer sleeve rod 231 to move up and down. In this embodiment of the device, when the height of the lifting knife is adjusted, or when the requirements of the processed fabric are different, the connection between the electromagnetic base 224 and the metal column 232 is disconnected by stopping the power supply to the electromagnetic base 224. At this time, the outer sleeve rod 231 is moved up and down by rotating the transmission plate 221 and driving the device including the motor and cylinder, so that the overall length of the lifting rod 23 changes and the position of the metal column 232 is adjusted. When the metal column 232 corresponds to the accurately calibrated electromagnetic base 224, the metal column 232 is connected to the electromagnetic base 224 by energizing it, so that the travel distance of the outer sleeve rod 231 changes and the travel distance of the lifting knife 5 is changed.

[0019] In this embodiment, please refer to Figure 5 , Figure 7 The drive mechanism 33 includes a first motor 331, the output end of which is fixedly connected to a second sprocket 332. Two second chains 333 are arranged on the outer side of the second sprocket 332, and a third sprocket 334 is arranged on one end of the inner wall of the second chain 333. The third sprocket 334 and the second sprocket 332 are both fixedly connected to the swing plate 342 through a connecting rod 345. In this embodiment, the first motor 331 provides power to control the rotation of the second sprocket 332, which in turn drives the second chain 333 to rotate. The second chain 333 drives the third sprocket 334 to rotate, and the rotation is transmitted through the connecting rod 345. This allows the swing plates 342 arranged in multiple control seats 34 to rotate simultaneously, adjusting the angle of the swing plates 342, thereby adjusting the tilt angle of multiple lifting blades 5 at the same time.

[0020] In this embodiment, please refer to Figure 3-4The inner cavity of the outer sleeve rod 231 has the same number of positioning slots 234 as the electromagnetic seats 224. One side of the inner sleeve rod 233 is provided with a positioning block 235 connected by a spring, and the two sides of the positioning block 235 are rounded. The distance between the center point of the multiple electromagnetic seats 224 and the center point of the transmission plate 221 is the same as the spacing between the multiple positioning slots 234. In this embodiment, when the outer sleeve rod 231 moves, it enters the inner cavity of the positioning slot 234 through the positioning block 235, which can cause the movement of the outer sleeve rod 231 to stop. Since the spacing between the positioning slots 234 is the same as the center spacing between the multiple electromagnetic seats 224 and the transmission plate 221, the metal column 232 can be positioned more accurately and quickly to the position of the electromagnetic seat 224 when the outer sleeve rod 231 moves.

[0021] In this embodiment, please refer to Figure 3 A spring 223 is provided on one side of the electromagnetic base 224. Both the inner and outer sides of the electromagnetic base 224 are set at bevels. In this embodiment, when the magnetic force of the electromagnetic base 224 disappears, the metal column 232 is disengaged from the inner cavity of the electromagnetic base 224 by rotating the transmission plate 221 due to the bevel. After the height of the metal column 232 is adjusted, the transmission plate 221 is rotated again to allow the metal column 232 to re-enter the inner cavity of the electromagnetic base 224 and complete the connection.

[0022] In this embodiment, please refer to Figure 7 A brake block 343 is fixedly connected to one end of the connecting rod 345. A metal block 344 is provided on one side of the brake block 343. When the corresponding surfaces of the metal block 344 and the brake block 343 are pressed together, the connecting rod 345 cannot rotate. An electromagnet is provided inside the brake block 343. When the electromagnet is energized, it attracts the metal block 344. In this embodiment, when the electromagnet inside the brake block 343 is energized, it attracts the metal block 344 to press against one side of the brake block 343, thereby preventing the connecting rod 345 from rotating. The lifting knife 5 can be fixed at this angle to prevent the angle of the lifting knife 5 from changing during the operation of the equipment.

[0023] In this embodiment, please refer to Figure 8 The lifting blade 5 is equipped with a distance sensor to detect the height difference between the lifting blade 5 and the calibration point. The lifting blade 5 is also equipped with an angle sensor and a displacement sensor. The angle sensor detects the tilt angle of the lifting blade 5 in real time, and the displacement sensor detects the horizontal position of the lifting blade. In this embodiment, the sensors detect the height, angle, and horizontal distance of the lifting blade, which facilitates the precise adjustment and correction of the lifting blade's position to ensure that the lifting blade maintains the correct posture during operation.

[0024] In this embodiment, please refer to Figure 1The mounting plate 1 is equipped with a controller, which includes a signal processing module for receiving and processing signals from the sensor to accurately calculate the position height information of the lifting knife 5. It also includes an adjustment control module that, based on the position height information, controls the movement of the cylinder and motor to automatically adjust the height, angle, spacing and stroke distance of the lifting knife. In this embodiment, after the jacquard machine accurately grasps the position information of the lifting knife, it can automatically correct the lifting knife.

[0025] Working principle of this invention: Step 1: The distance between the lifting blade 5 and the reference point is determined by emitting a laser and measuring its reflection time using a distance sensor. An angle sensor detects the angle between the lifting blade and the measuring point. A displacement sensor detects the horizontal position of the lifting blade. These sensors transmit the blade's position information to the controller. The controller activates cylinder 32, which pushes the adjusting seat 35 up and down to adjust the height of the lifting blade. The second motor 44 is activated to control the rotation of the third gear 45. Since the third gear 45 meshes with the second gear 43, its rotation drives the second gear 43 to rotate, which in turn drives the rotating shaft 42 to rotate. This rotation, in turn, drives the fourth gear 46 to rotate. Because the top of the rack 346 meshes with the outer edge of the fourth gear 46, when the fourth gear 46 rotates… The controllable rack 346 drives the fixed base 341 to move. By controlling the rotation direction of the fourth gear 46, the control base 34 is moved, thereby adjusting the horizontal position of the lifting blades 5 and the spacing between the lifting blades 5. The first motor 331 provides power to control the rotation of the second sprocket 332. The rotation of the second sprocket 332 drives the two second chains 333 to rotate. The rotation of the second chains 333 drives the rotation of the third sprocket 334. The rotation of the third sprocket 334 drives the rotation of the connecting rod 345. Since one end of the connecting rod 345 is connected to the swing plate 342, the angle of the swing plate 342 is adjusted. The change in the angle of the swing plate 342 causes the angle of the lifting blades 5 to change. The position information of the lifting blades 5 is confirmed by the sensor, and the position, angle and height of the lifting blades 5 are adjusted by the above components to achieve automatic correction. Step 2: By stopping the power supply to the positioning slot 234, the positioning slot 234 loses its magnetism after being de-energized, thus no longer attracting the metal column 232. At this time, by controlling the rotation of the transmission plate 221, since the inner wall of the electromagnetic base 224 is set as an inclined surface, when the transmission plate 221 rotates, the electromagnetic base 224 receives a thrust and moves backward, compressing the spring 223 and causing it to deform. At the same time, through the drive device set inside the swing seat 3, the outer sleeve rod 231 is controlled to move up and down, which can change the overall length of the lifting rod 23, causing the position of the metal column 232 to change. Simultaneously, the transmission plate 221 rotates, causing the metal column 232 to interact with the remaining electromagnetic... Corresponding to seat 224, since the outer side of electromagnetic seat 224 is also set at an angle, under the action of spring 223, metal column 232 can be connected to electromagnetic seat 224. After connection, by energizing electromagnetic seat 224, electromagnetic seat 224 generates magnetic force and attracts metal column 232 together, thereby fixing metal column 232 on electromagnetic seat 224. Since multiple electromagnetic seats 224 with different center distances are provided on the surface of transmission plate 221, by controlling the connection of metal column 232 with different electromagnetic seats 224, the stroke distance of outer sleeve rod 231 can be changed, thereby changing the stroke distance of the lifting knife driven by outer sleeve rod 231.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The present invention is not limited to the above embodiments; the embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this invention is defined by the appended claims and their equivalents.
