[0002] Currently, whether it's a domestic or foreign warping machine, the monitoring and adjustment of the PIV value for warp head flatness is done manually. This process presents the following problems:
[0003] 1. Manual operation, relying on the naked eye to monitor the flatness of the pan head, will produce a large error.
[0004] 2. The time required for manual operation is uncertain, resulting in a significant waste of time during the production process.
[0005] 3. Current warping machines cannot dynamically control the PIV value by adjusting the yarn separating needle in real time, and cannot make timely adjustments when errors occur.
[0006] 4. Current warping machines cannot automatically adjust the yarn separating needles, requiring manual shutdown and operation, which cannot meet the requirements of automated warping processes. Utility Model Content

[0026] Please see Figures 1 to 5 As shown, this utility model discloses an automatic yarn separating needle adjustment device for a warping machine, which works in conjunction with the warping machine frame 100 and a PLC controller. The automatic yarn separating needle adjustment device 200 is set at the front end of the warping machine head position 101 on the warping machine frame 100. It includes two yarn separating needle assemblies 1, two support plates 2, a yarn separating needle angle control mechanism 3, a yarn separating needle horizontal movement mechanism 4, and a fixed base plate 5. The two yarn separating needle assemblies 1 are respectively fixed above the corresponding support plates 2, and the adjacent ends of the two support plates 2 are pivotally connected to each other.
[0027] The yarn separating needle angle control mechanism 3 includes a first support frame 31, an opening and closing control servo motor 32, an opening and closing control ball screw 33, two first sliders 34, and a platform base 35. The opening and closing control servo motor 32 is fixed on the platform base 35 through the first support frame 31. One end of the opening and closing control ball screw 33 is connected to the opening and closing control servo motor 32. The middle part of the opening and closing control ball screw 33 passes through the two first sliders 34 and is threadedly connected to the two first sliders 34. The threads on the two first sliders 34 are in opposite directions. The top of each first slider 34 is fixedly connected to the corresponding support plate 2. The yarn separating needle angle control mechanism 3 is used to adjust the opening and closing angle of the two yarn separating needle components 1.
[0028] The yarn separating needle horizontal movement mechanism 4 is mounted on the fixed base plate 5 and includes a second support frame 41, a horizontal movement control servo motor 42, a horizontal movement control ball screw 43, and two second sliders 44. The horizontal movement control servo motor 42 is fixed to the fixed base plate 5 via the second support frame 41. One end of the horizontal movement control ball screw 43 is connected to the horizontal movement control servo motor 42, and the middle part of the horizontal movement control ball screw 43 passes through the two second sliders 44 and is threadedly connected to the two second sliders 44. The threads on the two second sliders 44 have the same direction. The yarn separating needle horizontal movement mechanism 4 is used to adjust the horizontal position of the two yarn separating needle assembly 1.
[0029] The opening / closing control servo motor 32 and the horizontal movement control servo motor 42 are respectively electrically connected to the PLC controller.
[0030] In a preferred embodiment, the automatic yarn separating needle adjustment device further includes a warp head flatness scanner 6. The warp head flatness scanner 6 is mounted on a scanner base 7, which is slidably connected to a transverse sliding rail 8. The transverse sliding rail 8 is mounted above the warp head mounting position 101 of the warping machine frame 100. The warp head flatness scanner 6 is electrically connected to the PLC controller. The warp head flatness scanner 6 is used to monitor whether the warp head is flat during the warping process.
[0031] In a preferred embodiment, the flatness scanner 6 is a laser rangefinder.
[0032] In a preferred embodiment, the transverse sliding track 8 is a rodless cylinder, the scanner base 7 is fixedly connected to the slider of the rodless cylinder, and the rodless cylinder is electrically connected to the PLC controller.
[0033] In another embodiment of this utility model, the working process is as follows:
[0034] 1. Once the warping is completed, warping begins. As the yarn begins to wind onto the warp head, the warp head flatness scanner 6 in the automatic yarn separating needle adjustment device 200 starts operating: the rodless cylinder receives the power-on signal from the PLC controller and then pushes the scanner base 7 to perform a cyclical movement at a preset speed to ensure that the laser rangefinder can maintain a uniform speed and vertically scan the warp head.
[0035] 2. The head flatness scanner 6 continuously scans during the head warping process and feeds back the distance measurement information to the PLC controller. Since horizontal movement takes time, the PLC controller will calculate the distance between the laser rangefinder and the head at the same time as the multiple distance measurement information collected in one movement scan, and compare whether the distance is equal when moving to the leftmost, rightmost and center points (there may be a slight error).
[0036] 3. If the above-mentioned point data error is large, the PLC controller will automatically adjust the yarn separating needle angle control mechanism 3 and the yarn separating needle horizontal movement mechanism 4. If yarn separating needle angle adjustment is required, the yarn separating needle angle control mechanism 3 will be activated: the opening and closing control servo motor 32 will receive feedback information from the PLC controller and drive the opening and closing control ball screw 33 to rotate, thereby adjusting the angle of the two yarn separating needle assemblies 1. If yarn separating needle horizontal position adjustment is required, the yarn separating needle horizontal movement mechanism 4 will be activated: the horizontal movement control servo motor 42 will receive feedback information and drive the horizontal movement control ball screw 43 to rotate, thereby adjusting the horizontal position of the yarn separating needle assembly 1 along with the platform base 35.
[0037] In other words, the device of this invention can use the above-mentioned automatic adjustment method to continuously monitor and self-adjust the flatness of the warp yarn until the warping is completed and output a high-quality product.
[0038] In summary, the beneficial effects of this utility model are as follows:
[0039] This invention features a yarn separating needle angle control mechanism and a yarn separating needle horizontal movement mechanism located below the yarn separating needle assembly. These mechanisms automatically adjust the angle and horizontal position of the yarn separating needle assembly, thereby controlling the yarn draft and ensuring high product quality. This also lays the foundation for continuous warping production and automated adjustment. Furthermore, it can be used in conjunction with a warp head flatness scanner and a lateral movement track to monitor warp head flatness using a precise laser rangefinder. Through real-time monitoring and feedback of warp head flatness, the angle and horizontal position of the yarn separating needle are automatically adjusted, significantly reducing warp head flatness errors.
