[0040] In one embodiment, as shown in the figure, the first height sensor 49 and the second height sensor 50 are respectively provided on the fourth connecting plate 37, and an indicator light 51 is provided on one side of the second frame 2. The first height sensor 49 and the second height sensor 50 check the height range of the floating stick at intervals, perform self-inspection, and eliminate external forces such as equipment. The indicator light 51 has the function of lighting up an alarm.
[0041] The above embodiment discloses a self-feedback linkage line speed regulating device. When in use, the third motor speed control panel 11 controls and adjusts the running speed of the third motor 10, thereby controlling the rotation speed of the third linkage roller 9, and the fourth motor speed control panel 15 controls and adjusts the running speed of the fourth motor 14, thereby controlling the rotation speed of the fourth linkage roller 13. The remaining first linkage rollers 3 are driven by the first chain 4 through the first motor 5, and the second linkage rollers 6 are driven by the second chain 7 through the second motor 8. The speed matching settings of the first motor 5 and the third motor 10 are the same, and the speed matching settings of the second motor 8 and the fourth motor 14 are the same, that is, when the speed of the fourth motor 14 is determined, the speed matching of the second motor 8 is the same as that of the fourth motor 14, thereby achieving a stable linkage line speed state. The upper half of the first frame 1 is measured by the front-stage linkage line speed measuring instrument 17 and displayed on the front-stage linkage line speed display panel 12. The upper half of the second frame 2 is measured by the rear-stage linkage line speed measuring instrument 18 and displayed on the rear-stage linkage line speed display panel 16. Set the preset range of the percentage difference of the front and rear linkage line speeds. For example: the percentage difference of the front and rear linkage line speeds is 5%, set the speed adjustment and speed display panel of the fourth motor 14, and the fourth motor 14 is displayed on the fourth motor speed control panel 15, so that it drives the fourth linkage roller 13 to move. When the rear linkage line speed measuring instrument 18 measures the speed of the rear linkage line, the rear linkage line speed measuring instrument 18 measures the actual speed of the half part, and the front linkage line speed measuring instrument measures the actual speed of the half part, the set speed of the fourth motor 14 is recorded at this time. (Due to kinetic energy loss, the fourth motor 14 ≠ the actual speed of the half-component measured by the rear-stage linkage linear speed measuring instrument 18), that is, the lowest point of the floating rod height, the actual speed of the half-component measured by the rear-stage linkage linear speed measuring instrument 18 reaches 105% of the actual speed of the half-component measured by the front-stage linkage linear speed measuring instrument 17, and the set speed of the fourth motor 14 at this time is recorded (due to kinetic energy loss, the fourth motor 14 ≠ the actual speed of the half-component measured by the rear-stage linkage linear speed measuring instrument 18), that is, the highest point of the floating rod height, thereby determining the preset control range of the positionable floating rod height.
[0042] When the front and rear speed difference percentage exceeds the preset range requirement (at this time the height range of the floating rod 48 is also out of tolerance), the positionable floating rod 48 provides feedback, and the fourth motor 14 adjusts the speed so that the height range of the floating rod 48 reaches the previous height preset range (the preset range of the front and rear speed difference percentage can be set to 5%), and the indicator light 51 turns red to alarm and perform speed adjustment; when the front and rear speed difference percentage is within the preset requirement range, but does not meet the more stringent standard range requirements, the speed measuring instrument measures the speed and feeds back to the motor, and the motor adjusts the speed to meet the more stringent standard requirement range (the more stringent standard requirement range can be set to 1%), and the indicator light 15 turns yellow to alarm and perform speed adjustment, and the front and rear speed difference percentage meets the more stringent standard range requirements, the indicator light 15 is green and qualified, and no speed adjustment is performed.
[0043] The speed measuring instrument continuously measures the front and rear speed difference in real time and records it, and calculates the front and rear speed difference percentage. If the height range of the floating rod 48 exceeds the previous height preset range, the feedback method is the positionable floating rod 48 feedback, because the positionable floating rod has sensitive feedback and responds quickly, but the accuracy is low. When the preset range is exceeded, a quick response is required, but when the front and rear speed difference percentage is within the preset requirement range, it does not meet the more stringent standard range requirements. At this time, the feedback method is the speed measuring instrument, which measures the speed and feeds it back to the motor, and the motor adjusts the speed to meet the more stringent standard requirement range. The feedback adjustment requires calculation, so the response speed is slow, but the accuracy is high. The height range of the floating rod is checked by the first height sensor 49 and the second height sensor 50 at intervals for a period of time, and self-checks to eliminate external forces such as equipment.
[0044] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
