Specific embodiments

[0024] Reference Figures 1-4 The utility model discloses a tensioning device for coaxial cable production, it includes support frame 1, support frame 1 whole presents T shape, and the both ends of support frame 1 are equipped with the mounting groove 11, and the mounting groove 11 is fixedly connected with tensioning mechanism 2, and the both ends of support frame 1 are symmetrically set up with tensioning mechanism 2, and the middle position of support frame 1 is equipped with sliding groove 3, and sliding groove 3 is fixedly connected with sliding rod 4, and sliding rod 4 is slidably connected with sliding block 6, and the sliding rod 4 of sliding block 6 upper side is sleeved with main spring 5, and under the action of main spring 5 and sliding block 6 in use process, the downward pressure is applied to cable 9, makes it taut, and the front side of sliding block 6 is equipped with conveying mechanism 7;

[0025] Tensioning mechanism 2 includes mounting plate 21, and mounting plate 21 is equipped with guide groove 22, and guide groove 22 is obliquely arranged on mounting plate 21, and guide rod 23 is fixedly connected in guide groove 22, and moving block 24 is slidably connected on guide rod 23, and auxiliary spring 25 is sleeved on the guide rod 23 of moving block 24 lower side, and conveying mechanism 7 is installed to the front side of moving block 24 and one side of mounting plate 21, and conveying mechanism 7 includes fixed rod 71, and tension wheel 72 is rotatably connected on fixed rod 71, and fixed rod 71 and tension wheel 72 are arranged on the both sides of sliding block 6, mounting plate 21 and the outside of moving block 24, and the upper side of tension wheel 72 is equipped with cable 9 on the both ends of support frame 1, and the upper side of tension wheel 72 is located on cable 9 in the middle position of support frame 1, if the pressure that cable 9 is received at main spring 5 is too big, the cable 9 of main spring 5 both sides is taut, at this moment, the pressure of cable 9 to the both ends of support frame 1 tensioning mechanism 2 increases, under the action of auxiliary spring 25, make moving block 24 drive conveying mechanism 7 move down, relieve the pressure of cable 9, and the angle of cable 9 in horizontal direction and cable 9 in vertical direction increases simultaneously, thereby avoiding cable 9 excessive bending, can further protect cable 9.

[0026] In another embodiment, a cleaning block 8 is installed on the right end support frame 1. The cleaning block 8 has a first mounting groove 81 and a second mounting groove 82 on its lower side. The second mounting groove 82 is located on both sides of the first mounting groove 81. A cleaning cloth 83 is installed in the second mounting groove 82 by Velcro. During the production process of the cable 9, the cable core is first wrapped with an insulating material by injection molding. Then the cable core is cooled by cooling water. After the cable core is cooled, the next operation is carried out. At this time, the cable core is tightened by the tensioning mechanism 2, and the cleaning cloth 83 inside the cleaning block 8 cleans the water stains on the cable 9.

[0028] During cable production, when cable 9 is subjected to traction, it moves to the right. At this time, under the action of the main spring 5 and the slider 6, downward pressure is applied to cable 9 to tighten it. Simultaneously, under the action of the tensioning mechanism 2 at both ends of the support frame 1, the tension of cable 9 is assisted. If the pressure on cable 9 at the main spring 5 is too great, cable 9 on both sides of the main spring 5 tightens. At this time, the pressure of cable 9 on the tensioning mechanism 2 at both ends of the support frame 1 increases. Under the action of the auxiliary spring 25, the moving block 24 drives the conveying mechanism 7 to move downward to relieve the pressure on cable 9. At the same time, the angle between cable 9 in the horizontal direction and cable 9 in the vertical direction increases, thereby preventing excessive bending of cable 9 and further protecting cable 9.
