[0018] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0019] Please refer to Figures 1-3, A wire and cable length measurement device, including a device frame 1. The inner side of the device frame 1 is rotatably connected with a frame shaft 2. A counting wheel 3 is arranged on the frame shaft 2. An encoder 4 is arranged on the device frame 1, and the encoder 4 is electrically connected to the counting wheel 3. The inner surface of the device frame 1 is rotatably connected with a rotating shaft 5 through a driving mechanism. A clamping rod 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A plurality of groups of wire grooves 7 are arranged on the outer surface of the clamping rod 6. A flexible pressing mechanism is arranged on the device frame 1.

[0020] Through the above technical solution, during the process of measuring the length of the wire and cable by this device, the cable passes through the wire grooves 7 on the surface of the clamping rod 6 and is placed on the counting wheel 3. The rotation of the counting wheel 3 will drive the coding disk inside the encoder 4 to rotate. Then, this mechanical movement is converted into an electrical signal through a photoelectric detector. The electrical signal is then processed and analyzed to achieve accurate measurement of the cable length. During this process, the driving mechanism and the flexible pressing mechanism can cooperate to stabilize the transmission trajectory of the cable, reducing shaking and deviation.

[0021] Specifically, the driving mechanism includes a motor 8 fixedly installed on the device frame 1. The output end of the motor 8 is fixedly connected with a driving wheel 9.

[0022] Through the above technical solution, when the motor 8 drives the driving wheel 9 to rotate, it will drive the driven wheel 11 to rotate through the transmission of the conveyor belt 10, and finally make the rotating shaft 5 rotate.

[0023] Specifically, the outer surface of the driving wheel 9 is slidably connected with a conveyor belt 10. One end of the inner side of the conveyor belt 10 far from the driving wheel 9 is slidably connected with a driven wheel 11, and the inner surface of the driven wheel 11 is fixedly connected with one end of the rotating shaft 5.

[0024] Through the above technical solution, the motor 8, the driving wheel 9, the conveyor belt 10 and the driven wheel 11 together form a transmission system, and the transmission wrap angle in this transmission system is greater than 120 degrees.

[0025] Specifically, the flexible pressing mechanism includes a displacement shaft 12 slidably connected to the inner side of the device frame 1. The outer surface of the displacement shaft 12 is rotatably connected with a clamping lever 13.

[0026] Through the above technical solution, the displacement shaft 12 can slide up and down along the inner side of the device frame 1 to adjust the distance from the rotating shaft 5.

[0027] Specifically, a plurality of groups of adapter rubber sleeves 14 are arranged on the outer surface of the clamping lever 13. A perforation 15 is arranged on the outer surface of the clamping lever 13.

[0028] Through the above technical solution, the adapter rubber sleeve 14 has the flexible characteristics of rubber. Its quantity is the same as that of the wire grooves 7 and the width is the same. At the same time, each adapter rubber sleeve 14 is just directly opposite to the corresponding wire groove 7 below.

[0029] Specifically, a fixed shaft 16 is fixedly connected to the top of the inner wall of the device frame 1 , and the outer surface of the fixed shaft 16 is movably inserted into the through hole 15 , and a spring 17 is movably sleeved on the outer surface of the fixed shaft 16 .

[0030] Through the above technical solution, the through holes 15 are designed near both ends of the displacement shaft 12 , and the fixed shaft 16 can pass through the through holes 15 , allowing the displacement shaft 12 to slide and displace along the fixed shaft 16 .

[0031] Working principle: During the measurement of wires and cables, the rotation of the meter wheel 3 will drive the encoder disk inside the encoder 4 to rotate, and then the photoelectric detector will convert this mechanical movement into an electrical signal. This electrical signal is then processed and analyzed to determine the rotation distance or number of turns of the meter wheel 3, thereby achieving accurate measurement of the cable length. During this process, the cable is allowed to pass through the wire groove 7 opened on the surface of the clamping rod 6, and in the process of the fixed axis 16 passing through the through hole 15, the shift axis 12 is moved to slide up along the fixed axis 16. During this process, the spring 17 is compressed. After the cable has stably passed through the wire groove 7, the hand is released. Under the elastic reset action of the spring 17, the shift axis 12 will be pushed down, thereby linking the clamping rod 13 to move down until the adapter rubber sleeve 14 is against the cable with elastic force. Since the cable is effectively constrained and positioned in the flexible extrusion, its length is not easy to change during the transmission process, thereby reducing the measurement error caused by factors such as cable stretching, contraction or twisting, and Unlike the rigid extrusion mechanism, the flexible pressing mechanism uses a flexible force to resist the cable, avoiding cable damage caused by excessive extrusion, such as insulation damage, conductor deformation, etc. This flexible pressure can ensure that the cable maintains its original structure and performance while being squeezed, and the height of the shift shaft 12 can be automatically adjusted according to the specifications and materials of the cable to meet the extrusion requirements of different cables. In the process of cable transmission and metering length, the motor 8 can be turned on to drive the drive wheel 9 to rotate, and the conveyor belt 10 can be linked to the transmission wheel 11 to rotate synchronously, and finally the rotating shaft 5 and the ferrule rod 6 are rotated. During this rotation process, the rotating shaft 5 provides a dynamic support and guiding effect for the cable, so that the cable can maintain a stable transmission path and speed. This stability helps to reduce the vibration and deviation of the cable during transmission, ensure the accuracy of measurement, and enable the cable to be evenly stressed when passing through the extrusion mechanism, avoiding local wear caused by single-point contact or excessive extrusion.

[0032] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
