Through automated control and data recording, the meter measuring device provides an efficient and reliable solution for cable production, making it an indispensable key piece of equipment in modern cable production lines.
[0030] However, traditional metering wheels are usually fixed on the equipment and cannot be moved flexibly, making it difficult to adjust their position when the working environment or cable specifications change. Furthermore, since the metering wheel and its supporting structure are heavy, they need to be disassembled or tools are required when moving them, which is cumbersome and time-consuming. At the same time, the lateral distance adjustment between the metering wheel and the clamping wheel usually relies on manual operation and lacks a quick adjustment mechanism, making it difficult to adapt to cables of different diameters.
[0031] To address the aforementioned problems, this application proposes a cable length measuring device. The embodiments of this application will be further described below with reference to the accompanying drawings.

The rear idler assembly, the front guide wheel 111 assembly, the rear guide wheel 112 assembly, the front idler assembly, and the rear idler assembly are all mounted on the worktable 110. The front idler assembly and the rear idler assembly are symmetrically arranged at both ends of the worktable 110, and the front idler assembly and the rear idler assembly are also symmetrically arranged at both ends of the worktable 110. The front idler assembly and the rear idler assembly are both located between the front guide wheel 111 assembly and the rear guide wheel 112 assembly. The worktable 110 is mounted on an electric lifting rod. The sliding mechanism includes a first drive motor. The structure includes a first drive mechanism, a second drive mechanism, a first slider 117, a second slider, and a slide rail 118. A control device is connected to the first drive mechanism, the second drive mechanism, and the electric lifting rod, respectively. The slide rail 118 is mounted on the worktable 110 and is positioned between the front and rear roller assemblies. Both the first slider 117 and the second slider are slidably mounted on the slide rail 118. The pressure roller shaft 132 seat 131 is mounted on the first slider 117, and the meter wheel shaft seat 121 is mounted on the second slider.

[0033] It should be noted that the pressure roller 130 is sleeved on the pressure roller shaft 132 and connected to the first slider 117 through the pressure roller shaft 132 seat 131. It moves on the slide rail 118 with the first slider 117. The cable measuring roller 120 is sleeved on the measuring roller shaft and connected to the second slider through the measuring roller shaft seat 121. It moves on the slide rail 118 with the second slider. This method of adjusting the lateral position of the pressure roller 130 and the cable measuring roller 120 can effectively shorten the adjustment time and improve production efficiency.
[0034] It should be noted that the independent adjustment of the pressure wheel 130 and the cable measuring wheel 120 is achieved through the combination of the slide rail 118, the slider, and the drive mechanism, resulting in a simple structure and high adjustment accuracy. The vertical adjustment of the worktable 110 is achieved through the electric lifting rod, further expanding the applicability of the device. The combination of the rotary encoder 123 and the electronic counter 124 enables accurate measurement and data recording of the cable length, improving metering accuracy and traceability. Integrating the control of the sliding mechanism and the electric lifting rod into one system simplifies the operation process.
[0035] In this application, the lateral position adjustment of the pressure wheel 130 and the measuring wheel is achieved through a sliding mechanism, the vertical position adjustment of the worktable 110 is achieved through an electric lifting rod, and the accurate measurement of the cable length is achieved through a rotary encoder 123 and an electronic counter 124. The front guide wheel 111 assembly and the rear guide wheel 112 assembly guide the cable into and out of the measuring device to ensure smooth cable operation. The front and rear support roller assemblies are symmetrically arranged at both ends of the worktable 110 to support the cable and reduce friction. The rotary encoder 123 is fixedly connected to the measuring wheel shaft and measures the rotation angle of the measuring wheel. The electronic counter 124 is electrically connected to the rotary encoder 123 and calculates the cable length and displays it in real time. The control device drives the first slider 117 to move laterally on the slide rail 118 through the first drive mechanism. The control device is also used to drive the second slider to move laterally on the slide rail 118 via the second drive mechanism, and to control the raising and lowering of the electric lifting rod. The lateral position of the pressure roller 130 and the measuring wheel can be quickly and accurately adjusted by setting up the sliding mechanism, and the vertical position of the pressure roller 130 and the cable measuring wheel 120 can be adjusted by setting up the electric lifting rod, making the cable length measuring device adaptable to cables of different diameters and types, improving the equipment's versatility. The combination of the rotary encoder 123 and the electronic counter 124 ensures high accuracy in cable length measurement and reduces errors. The symmetrical arrangement of the roller mechanism and guide wheel assembly ensures smooth cable operation and reduces vibration and sway. The integrated design of the control device allows operators to easily adjust the positions of the pressure roller 130, the measuring wheel, and the worktable 110 via the control panel. This application can be flexibly used on different production lines or equipment, improving the equipment's versatility and utilization, and effectively improving operational convenience and measurement accuracy.

The distance between the two guide wheels 111 can be adjusted according to the cable diameter to ensure close contact between the cable and the guide wheels 111, improving the versatility of the device and adapting to the production needs of various cable specifications. The guide wheels 111 are installed on the worktable 110 through the first moving hole, and their positions can be flexibly adjusted to ensure that the contact pressure between the cable and the guide wheels 111 is moderate, reducing friction and wear of the cable during operation and extending the cable's service life.
