[0012] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0013] Embodiment 1:

[0014] like Figure 1 , Figure 2As shown, the utility model discloses a cable winding device, including a frame 1, a winding roller 3 and a power mechanism 2 arranged on the frame 1, the power mechanism 2 is connected to the winding roller 3 by transmission, a length measuring mechanism 4 is arranged on the frame 1 in front of the winding roller 3, the length measuring mechanism 4 includes two vertical plates 41 arranged on the frame 1, a first guide roller 42, a second guide roller 43, and a third guide roller 44 are arranged between the two vertical plates 41, and the first guide roller 42, the second guide roller 43, and the third guide roller 44 are connected to the vertical plates 41 by transmission. The first guide roller 42, the second guide roller 43 and the third guide roller 44 are used to tension the cable 7 to be wound, a stopper 47 is arranged on the side of one end of the first guide roller 42, and two induction switches 48 are arranged at intervals on the corresponding vertical plate 41 on the same side. During the rotation of the first guide roller 42, the stopper 47 passes between the two induction switches 48; a controller and a display are also included, the controller is used to record the number of times the stopper 47 passes between the induction switches 48 and convert it into length, and the display is used to display the length value.

[0015] The power mechanism 2 can be a combination of a motor 55 and a reducer, and the reducer finally drives the winding roller 3 to rotate to increase the winding force. The cable 7 to be wound passes between the three guide rollers, such as the cable 7 passes between the first guide roller 42 and the second guide roller 43, and then passes between the first guide roller 42 and the third guide roller 44. In this process, the cable 7 is tensioned so that the cable 7 partially fits the surface of the first guide roller 42. During the transportation process, the cable 7 and the first guide roller 42 move synchronously. The above process not only completes the tensioning of the cable 7, but also completes the length measurement of the cable 7. When the cable 7 drives the first guide roller 42 to rotate, the block 47 at the end of the first guide roller 42 also moves in a circle with the first guide roller 42. When the block 47 rotates with the first guide roller 42 and passes through the two induction switches 48 once, it means that the block 47 and the first guide roller 42 rotate one circle. The induction switch 48 is a photoelectric induction, specifically an existing commercially available product. The induction switch 48 transmits the number of times the block 47 passes and the number of turns of the first guide roller 42 to the controller, and the circumference of the first guide roller 42 is pre-entered in the controller. According to the number of turns, the controller can calculate the length of the cable 7 passing through the first guide roller 42 and transmit the signal to the display for display. The display and controller are not shown in the figure.

[0016] The first guide roller 42, the second guide roller 43, and the third guide roller 44 are arranged in contact with each other on the surface. An arc groove 45 is arranged on the surface of the first guide roller 42, the second guide roller 43, and the third guide roller 44, and the positions of the arc grooves 45 correspond to each other. The diameter of the arc groove 45 matches the diameter of the cable 7 to be wound. The diameter of the arc groove 45 matches the diameter of the cable 7 to be wound, which means that the diameter of the cable 7 to be wound is equal to or slightly larger than the diameter of the arc groove 45, so that the circumferential side wall of the cable 7 to be wound is in contact with the arc groove 45 on the first guide roller 42, the second guide roller 43, and the third guide roller 44, and a certain pressure and friction force are generated to ensure that the cable 7 to be wound can run synchronously with the first guide roller 42, thereby improving the accuracy of length measurement. At the same time, the design of the arc groove 45 can synchronize the transmission between the cable 7 to be wound and the first guide roller 42, and always keep it in a radial cross section, further improving the measurement accuracy.

[0017] A rubber layer 46 is compounded in the arc groove 45. The design of the rubber layer 46 can effectively increase the friction between the arc groove 45 of the first guide roller 42, the second guide roller 43, and the third guide roller 44 and the cable 7 to be wound, and also make the arc groove 45 adapt to the cable 7 to be wound with a slightly larger diameter, improve the synchronization of the operation of the cable 7 and the first guide roller 42, and make the length measurement more stable.

[0018] A guide mechanism 5 is provided on the frame 1 between the winding roller 3 and the length measuring mechanism 4. The guide mechanism 5 includes a screw rod 51 and a guide rod 52. The screw rod 51 is parallel to the guide rod 52. The axial direction of the screw rod 51 is parallel to the axial direction of the winding roller 3. A slider 53 is provided on the screw rod 51 and the guide rod 52. A screw hole is provided on the slider 53 to match the screw rod 51. A guide hole is provided on the slider 53 to match the guide rod 52. A motor is provided on the frame 1 at one end of the screw rod 51. The motor is connected to the screw rod 51 in a transmission manner. A guide ring 54 is provided on the slider 53. The cable 7 to be wound passes through the guide ring 54. In order to make the cable 7 to be wound on the winding roller 3 more uniformly, the guide mechanism 5 reciprocates the cable 7 entering the winding roller 3. The motor is a servo motor 55, which realizes reciprocating and alternating rotation, so that the slider 53 reciprocates on the guide rod 52 and the screw rod 51. The guide ring 54 has an internal opening for the cable car to pass through, and the inner wall of the guide ring 54 is as smooth as possible to reduce the friction between the guide ring and the cable 7 and avoid damage to the cable 7.

[0019] Two limiting rollers 6 are arranged on the frame 1 between the metering mechanism and the guide mechanism 5. The axial direction of the limiting roller 6 is arranged vertically. The limiting roller 6 is rotatably connected to the frame 1, and the cable 7 to be wound passes between the two limiting rollers 6. Since the amplitude of the reciprocating motion of the cable 7 driven by the guide mechanism 5 is determined according to actual needs, it needs to match the length of the winding roller 3. However, when the movement amplitude is too large, it is easy to cause the cable 7 to move out of the arc groove 45, or the edge of the arc groove 45 will cause indentation to the cable 7, affecting the quality of the cable 7. Therefore, two limiting rollers 6 are used to limit the angle between the cable 7 and the first guide roller 42 to avoid damage to the cable 7 and improve product quality.
