[0016] like Figures 1 to 5As shown, the present invention is a production equipment of a reinforced mining rubber sheathed cable, including a mounting base plate 1, a vertical plate 4 is provided on the mounting base plate 1, one end of the vertical plate 4 is fixed on the mounting base plate 1, a mounting through hole is provided on the other end of the vertical plate 4, a rotating bearing 5 is provided inside the mounting through hole, the outer ring of the rotating bearing 5 is fixed on the inner side surface of the mounting through hole, a rotating tube 2 is provided on the inner ring of the rotating bearing 5, one end of the rotating tube 2 is fixed on the rotating bearing 5, a rotating disk is provided on the other end of the rotating tube 2, a wire passing hole is provided in the middle of the rotating disk, the end of the rotating tube 2 is fixed on the outer side surface of the wire passing hole, a mounting shell 21 is provided on the rotating disk, a slider 23 is provided inside the mounting shell 21, the slider 23 is slidably connected in the mounting shell 21, and the slider 23 slides in the radial direction of the rotating disk, and the slider 23 and the mounting shell 21 are close to the middle of the rotating disk. A spring 22 is provided on one end of the mounting shell 21, one end of the spring 22 is fixed on the slider 23, and the other end of the spring 22 is fixed on the inner side surface of the mounting shell 21. A fixing rod is provided on the end of the slider 23 facing the outer side of the mounting shell 21, one end of the fixing rod is vertically fixed on the slider 23, and a flame-retardant layer reel 20 is provided on the other end of the fixing rod. A mounting ring 10 with a U-shaped cross-section is provided on the outer side of the fixing rod. The mounting ring 10 is fixed on the mounting base plate 1, and the mounting ring 10 and the turntable are concentrically arranged. An annular airbag 12 is provided inside the mounting ring 10, and the outer surface of the annular airbag 12 is fixed on the inner side surface of the mounting ring 10. A roller 24 is provided on the fixing rod, and the roller 24 is tightly arranged on the annular airbag 12. An adjusting mechanism for adjusting the volume of the annular airbag 12 according to the change in the diameter of the cable core 25 is provided on the outer side of the mounting ring 10.

[0017] The working principle of the above technical solution is: The diameter change of the cable core 25 is monitored by the adjustment mechanism. For example, when the diameter of the cable core 25 of a certain section becomes larger (especially for large-diameter cables, the diameter change is more obvious), the adjustment mechanism controls the annular airbag 12 to expand, that is, the expanded annular airbag 12 will squeeze the roller 24 downward, and the roller 24 will drive the slider 23 to move downward, that is, the downward moving slider 23 will drive the flame retardant layer reel 20 to move downward, so that the flame retardant layer that is tightened during the winding process becomes relatively loose, and the diameter of the cable core is relatively large, that is, the relatively loose flame retardant layer is wound around the cable core 25, and the degree of winding will not be too tight, that is, there will be no occurrence of the flame retardant layer being wound around the cable core 25 due to the cable. Cable bending causes collapse; when the diameter of the cable core 25 of a certain section becomes smaller, the volume of the annular airbag 12 decreases, that is, the spring 22 drives the roller 24 to move upward, that is, the flame retardant layer drum 20 moves upward, so that the flame retardant layer is relatively tight, that is, the relatively tight flame retardant layer is wrapped around the cable core 25 with a relatively small diameter, and the degree of winding is relatively tight, so the tightness after winding meets the design requirements (it is not difficult to understand that the winding tightness of the flame retardant layer does not need to be controlled too accurately, so in this technical solution, the flame retardant layer drum 20 is not considered. As the winding time becomes longer, the flame retardant layer becomes thinner, which affects the winding density).

[0018] That is, the structure provided in the present technical solution can adjust the tightness of the flame retardant layer winding according to the change of the cable core diameter. That is, when performing annular winding, the tightness of the winding can be compensated and adjusted by adjusting the tightness of the flame retardant layer, thereby improving the production effect of the rubber sheathed cable.

[0019] In an practicable manner, it also includes a driving wheel 8, a driven wheel 6, a driving belt 9 and a rotating motor 7. The driven wheel 6 is arranged on the rotating tube 2, the driving wheel 8 is arranged on the output shaft of the motor, the driving belt 9 is wound around the driving wheel 8 and the driven wheel 6, and the rotating motor 7 is fixed on the mounting base plate 1. The rotating motor 7 drives the rotating shaft and the rotating disk 3 to rotate, and then drives the flame retardant layer reel 20 to rotate, thereby achieving the purpose of annular winding of the flame retardant layer. Of course, the flame retardant layer reel 20 should be arranged on the winding reel 19. This is a prior art, and reference can be made to the winding mechanism or device of the annular product, and no further elaboration will be made here.

[0020] In one feasible manner, the inner side surface of the mounting shell 21 is symmetrically provided with ridges in the length direction, and the slider 23 is provided with grooves corresponding to the ridges, and the grooves are slidably connected to the ridges. The mounting shell 21 is a rectangular frame surrounded by four side panels, which limits the horizontal displacement of the slider 23 so that it can only move up and down.

[0021] In one practicable manner, the adjustment mechanism includes a plurality of arc-shaped push blocks 11 arranged on the side of the mounting ring 10, the arc-shaped push blocks 11 are slidably connected to the mounting ring 10, and one end of the arc-shaped push blocks 11 abuts against the annular airbag 12, and a pushing component is provided on the other end of the arc-shaped push blocks 11, and the pushing component is used to drive the arc-shaped push blocks 11 to move, thereby changing the degree of squeezing of the annular airbag 12.

[0022] Specifically, the pushing assembly includes a sliding rod 13 arranged between adjacent annular push blocks, one end of the sliding rod 13 is fixed to the side of the mounting ring 10, a wedge block 15 is provided on the sliding rod 13, and connecting rods 14 are symmetrically provided on the wedge block 15, one end of the two connecting rods 14 are fixed to the wedge block 15, and the other ends are respectively fixed to the ends of two adjacent arc-shaped push blocks 11, and an L-shaped rod 16 is also provided on the sliding rod 13, one end of the L-shaped rod 16 is fixed to the sliding rod 13, and the other end of the L-shaped rod 16 is provided with a slip ring 17, and a push rod 18 is provided inside the slip ring 17, one end of the push rod 18 contacts the surface of the cable core 25, and the other end of the push rod 18 contacts the wedge surface of the wedge block 15.

[0023] The working principle of the above technical solution is: The end of the push rod 18 is in contact with the cable core 25, so the diameter change of the cable core can be sensed. For example, when the diameter of the cable core increases, the push rod 18 is pushed to move close to the wedge block 15. Since the vertical position of the wedge block 15 is limited, the wedge block 15 will move close to the mounting ring 10 on the sliding rod 13, thereby driving the connecting rod 14 to move, and then pushing the arc push block 11 to move, thereby squeezing the annular airbag 12, and then squeezing the roller 24 and the slider 23 downward, thereby reducing the tension of the flame retardant belt. The degree of winding of the large diameter cable core 25 is compensated, and the winding tightness of the flame retardant tape is within a reasonable range. Similarly, when the diameter of the cable core 25 becomes smaller, the top rod 18 is out of contact with the wedge block 15, that is, the limit on the wedge block 15 and the arc push block 11 is lost, and the spring 22 pushes the slider 23 to move upward, making the flame retardant tape relatively tighter, thereby achieving compensation. It is not difficult to understand that the wedge block 15 should be limited on the sliding rod 13 to prevent it from rotating, and the limit can be achieved by means of ridges and grooves.

[0024] In an practicable manner, a stopper is provided on the other end of the sliding rod 13 , and the stopper and the end of the sliding rod 13 are detachably connected, and rounded head portions are provided on both ends of the top rod 18 .

[0025] In an practicable manner, the push assembly includes a distance sensor and a linear push rod. The distance sensor is fixed on the vertical plate 4 to monitor the diameter change of the cable core 25. The output end of the linear push rod is fixed on the end of the arc push block 11. The distance sensor sends an output signal to the linear push rod according to the monitored diameter change information of the cable core 25 to control the telescopic stroke of the linear push rod, thereby adjusting the volume of the annular airbag 12. In this way, the diameter of the cable core 25 is accurately monitored by electronic control and program control (existing technology), and then the expansion of the airbag volume is accurately controlled, and then the tightness of the flame retardant tape is accurately compensated and adjusted. It can be selected according to the actual processing scene and requirements. Of course, it is not understandable that the distance that the slider 23 moves up and down is relatively small, and it only adjusts the tightness of the flame retardant tape. It can be understood that when manually winding, the manually tightened flame retardant tape will be wound tighter. If the winding tape is in a relaxed state, it will also be in a relaxed state after winding.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
