Technical Field

[0001] The present invention relates to the technical field of diameter detection, and in particular to a diameter detection device for manufacturing electric wires and cables. Background Art

[0002] The diameter detection equipment used in wire and cable manufacturing mainly refers to the online diameter gauge, which can be used for online detection and control of the outer diameter of wires and cables. The diameter detection link is crucial to the quality of the entire cable.

[0003] In the prior art, when the cable diameter is detected, the outer surface of the cable may become rough due to defects such as pits and scratches on its surface.

[0041] The third spring 617 is arranged in an annular shape and its axis is consistent with the rotating ring 62 .

[0042] The axis centers of the side ring 61 and the rotating ring 62 are consistent, so that the cable can pass through in a straight line.

[0043] The effects achieved by this embodiment are as follows: In the prior art, the outer surface of the cable may become rough due to the influence of defects such as pits and scratches on its surface. In addition, the position of the outer surface of the cable at the probe of the detection device will also change due to different specifications and sizes of the cable. Therefore, these two factors will affect the accuracy of the cable diameter detection and its quality and safety. Compared with the prior art, through the implementation of this embodiment, the uniformity improvement mechanism 6 is set to start the heating ring 618 at the same time, and under the heat conduction effect of the heat conductive plate 619, the multiple anti-sticking plates 620 located on the outside of the cable rotate, which is equivalent to heating a circle on the outside of the cable, and can also adapt to the size of the cable. In the process of continuous routing, the surface of the cable can be continuously heated so that its surface is slightly melted and reshaped, thereby automatically enhancing the uniformity of the outer surface and timely detecting defects such as pits and scratches.

[0044] For further examples, please refer to Figure 1 , Figure 2 , Figures 8 to 10As shown, the reciprocating mechanism 7 includes an adjusting platform 75, which is fixedly connected to the top of the fixed platform 4 on one side away from the side ring 61. A pair of connecting plates 78 are fixedly connected to the top of the adjusting platform 75. The tops of the pair of connecting plates 78 are rotatably connected to pulleys 77, and the outer walls of the pair of pulleys 77 are jointly meshed and connected to a circular belt 72.

[0045] The reciprocating mechanism 7 also includes a support rod 74, the bottom of the support rod 74 is fixedly connected to the side of the adjustment platform 75 away from the circular belt 72, the top of the support rod 74 is fixedly connected to the bottom wiping cloth 71, the side of the pulley 77 away from the support rod 74 is fixedly connected to a pair of short plates 79, the outer walls of the pair of short plates 79 are connected to an elastic belt 73 for rotation together, and the side of the elastic belt 73 close to the circular belt 72 is fixedly connected to a top wiping cloth 76.

[0046] A pair of short plates 79 are arranged in opposite directions, and the sides of the short plates 79 close to each other are connected to the rotating shaft of the pulley 77.

[0047] Wherein: the elastic force of the elastic band 73 is smaller than the displacement of the short plate 79 when it rotates alternately.

[0048] The effects achieved by this embodiment are as follows: In the prior art, the air in the processing workshop is generally dusty, and when it comes to the later diameter detection process, dust may easily accumulate on the top of the cable, which will have an adverse effect on the diameter of its outer surface and other detections. Compared with the prior art, through the implementation of this embodiment, a self-reciprocating mechanism 7 is set to be able to rotate the pulley 77 under the friction between the cable and the circular belt 72, and the short plates 79 located on both sides of the pulley 77 are continuously rotated alternately, and the two ends of the elastic band 73 are continuously pulled alternately, and finally the top wiping cloth 76 can be moved slightly laterally back and forth, so that the upper surface of the cable that is prone to dust can be effectively removed, and the bottom wiping cloth 71 can ensure that the outer surface of the cable is clean and dust-free, which is beneficial to the subsequent uniformity improvement and diameter detection effect.

[0049] The complete use steps and working principle of the above embodiment are as follows: In the initial state: the U-shaped frame 67 is located on the top of the ratchet bar 68, and the first spring 611, the second spring 614, the third spring 617 and the fourth spring 621 are all in a natural relaxation state.

[0050] When in use, the staff first passes the cable to be detected through the middle of a pair of side rings 61, and uses the second spring 614 to squeeze the positioning plate 615 to contract each other, so as to center the cable at the center of the side ring 61. The cable moves in the direction away from the side ring 61 and passes through a pair of wire rollers 5. The wire rollers 5 can be pressed downward according to the size specifications of the cable itself. At the same time, the wire rollers 5 drive the U-shaped frame 67 to move downward, so that the pawl 610 is continuously squeezed and rotated, and is clamped to the bottom of the heating ring 618 until it automatically adapts to the size of the cable. The tension of the fourth spring 621 keeps the U-shaped frame 67 in the current position, that is, the cable is in the middle position of the detector 2, and the diameter is detected by the measured head 3. With the cooperation of the U-shaped frame 67 and the positioning plate 615, the outer diameter of the cable is adaptive to meet the centering detection of cables of different specifications, thereby improving the detection accuracy.

[0051] Furthermore, during the continuous inspection of the cable, the staff simultaneously starts the servo motor 612 to drive the gear 613 to rotate, and then drives the gear ring 65 and the rotating ring 62 to rotate synchronously. Since the side ring 61 remains in the threaded state at this time, the cable is also centered in the middle of the anti-sticking plate 620. When the rotating ring 62 rotates, the multiple anti-sticking plates 620 located outside the cable also rotate, and cooperate with the heater 64 to heat the heating ring 618. Under the heat conduction effect of the heat conductive plate 619, it is equivalent to heating a circle on the outside of the cable, and can also adapt to the size of the cable. In the process of continuous routing, the surface of the cable can be continuously heated so that its surface is slightly melted and reshaped, thereby eliminating minor defects such as pits and scratches, and automatically enhancing the uniformity of its outer surface.

[0052] Please refer to the above working process Figures 1 to 7 .

[0053] Furthermore, before the diameter detection, the cable must first pass through the self-reciprocating mechanism 7 so that its bottom is in contact with the bottom wiping cloth 71 and the top is in contact with the top wiping cloth 76. Then, in the process of continuous routing, the friction between the cable and the return belt 72 can continuously drive the return belt 72 to move in one direction, thereby causing the pulley 77 to rotate, and the short plates 79 arranged in opposite directions on both sides of the pulley 77 continuously rotate alternately, and then the two ends of the elastic band 73 are continuously pulled alternately through the short plates 79. Since the elastic force of the elastic band 73 is less than the displacement of the alternating rotation of the short plates 79, when the short plates 79 rotate alternately, the elastic band 73 can be driven to move back and forth laterally, and finally the top wiping cloth 76 is made to make a slight reciprocating laterally movement, which can cooperate with the bottom wiping cloth 71 to ensure that the outer surface of the cable is clean and dust-free, and the upper surface of the cable that is prone to dust is increased by lateral reciprocating friction, and the dust removal effect is good.

[0054] Please refer to the above working process Figure 1 , Figure 2 , Figures 8 to 10 .

[0056] Although embodiments of the present invention 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 invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
