[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, a computer instrument cable is mainly composed of a cable core, a flame retardant layer 6, a heat insulation layer 7, and a wear-resistant sheath 8 which are sequentially coated on the outside of the cable core.

[0025] Furthermore, the cable core is composed of a conductive conductor 1, three transmission conductors 2, an insulating layer 3, heat-conducting particles 4, and a cable core shielding sheath 5. The conductive conductor 1 is located at the center, and the three transmission conductors 2 are twisted around the conductive conductor 1. The insulating layer 3 is correspondingly coated on the outside of the conductive conductor 1 and the three transmission conductors 2 to insulate each other; the heat-conducting particles 4 are filled inside the cable core. In this embodiment, the heat-conducting particles 4 are graphite, which can conduct the heat generated by the conductor to the cable core shielding sheath 5 and diffuse the heat outward to the flame retardant layer 6. The flame retardant layer 6 and the heat insulation layer 7 play the role of flame retardancy and heat insulation, forming a double-layer protective structure to achieve the purpose of reducing the temperature or fire. The flame retardant layer 6 not only plays the role of flame retardancy, but also has the function of absorbing heat. In this embodiment, the flame retardant layer 6 is a halogen-free flame retardant braided rope; in this embodiment, the heat insulation layer 7 is heat insulation cotton.

[0026] like Figures 2 to 6 As shown, a computer instrument cable winding device is used in the production of the above-mentioned computer instrument cable, including a winding frame 11, a lifting mechanism 33 arranged on both sides of the winding frame 11, and a winding roller 22 arranged on the lifting mechanism 33. A winding power mechanism 44 that can drive the winding roller 22 to rotate and wind is arranged on one side of the upper end of the winding frame 11, and support components 55 that can cooperate with the lifting mechanism 33 to assist in supporting the winding roller 22 when winding are arranged on both sides of the upper end of the winding frame 11.

[0027] The winding roller 22 is arranged on the lifting mechanism 33, and is lifted and lowered by the lifting mechanism 33. When it rises to the upper limit position, the winding roller 22 will cooperate with the winding power mechanism 44, and the winding power mechanism 44 drives the winding roller 22 to rotate, so as to implement winding. During the winding process, the support assembly will slide to the bottom of the winding roller 22 and cooperate with the lifting mechanism 33 that carries the winding roller 22 to provide auxiliary support to prevent the shaking of the winding roller 22 during winding from affecting the lifting structure; after the winding is completed, the cable is cut, the support assembly is reset, and the lifting mechanism 33 drives the winding roller 22 to descend to the bottom of the winding frame 11, so that the lifting mechanism 33 is separated from the winding roller 22, and the winding roller 22 can be pushed out from one side of the winding frame 11. Compared with the prior art, this device does not require the use of lifting equipment, is easy to operate, and is easy to place and remove.

[0028] As a further improvement of this embodiment, the winding frame 11 includes two symmetrically distributed bottom frame plates 111, two symmetrically arranged connecting frame columns 112 on the two bottom frame plates 111, and two upper frame plates 113 arranged on the upper ends of the two connecting frame columns 112. Two guide grooves 1111 distributed along the left and right directions are arranged on the two bottom frame plates 111. The two guide grooves 1111 are aligned with the two supporting side plates on the winding roller 22 in the upper and lower positions and the sizes are adapted. The guide grooves 1111 play a role in providing the winding roller 22 with a directional guide when it is pushed out, so as to prevent the direction from being offset and hitting the winding frame 11 when it is pushed out.

[0029] As a further improvement of this embodiment, the lifting mechanism 33 includes two symmetrical lifting screws 331, two bearing plates 332 arranged on the two lifting screws 331, two transmission bevel gears 334 coaxially connected to the lower ends of the two lifting screws 331, two driving bevel gears 335 meshing with the two transmission bevel gears 334, a driving shaft 336 connected to the two driving bevel gears 335, and a driving motor 337 connected to the driving shaft 336. The upper ends of the two lifting screws 331 are connected to the bottoms of the two upper frames 113, and the lower ends pass through the two bottom frames 111. Furthermore, two bearing seats 333 are arranged on the two bearing seats 332, and the winding roller 22 is installed on the two bearing seats 333 through the outer end roller shaft. A motor mounting seat 338 is arranged on the front side of the front side bottom frame plate 111 of the two bottom frames 111, and the driving motor 337 is installed on the motor mounting seat 338. The two sets of lifting screw rods 331 can ensure the balance of the lifting force and improve the structural stability; the bearing seat 333 ensures the smoothness of the rotation of the winding roller 22 when winding.

[0030] As a further improvement of this embodiment, the winding power mechanism 44 includes a driving friction roller 441 and a winding motor 442 arranged on the front upper plate 113 among the two upper plates 113, and a transmission friction roller 443 arranged on the roller shaft at the outer end of the winding roller 22, and the driving friction roller 441 is located above the transmission friction roller 443 and contacts and abuts against it.

[0031] As a further improvement of this embodiment, the support assembly 55 includes two groups of support plates 551 located at the lower side of the two upper shelves 113 and sliding horizontally, each group of support plates 551 is composed of two left-right symmetrical support plates 551, and the support plates 551 are L-shaped. Four guide slides 552 are arranged on the left and right sides of the lower side of the two upper shelves 113, and the four support plates 551 are correspondingly slidably installed in the four guide slides 552. One end of the support plate 551 slides in the guide slide 552, and its end extends from the guide slide 552 to form a pushing handle, and an anti-slip sleeve is installed on the handle to facilitate pushing the support plate 551.

[0032] After the support plate 551 slides inward, it can fit with the bottom of the bearing plate 332 in the lifting mechanism 33, thereby improving the bearing capacity of the bearing plate 332 and preventing the weight of the winding roller 22 from increasing and exceeding the bearing capacity of the bearing plate 332 as the winding process deepens, thereby damaging the structure of the lifting mechanism 33.

[0033] The working principle and use process of the winding equipment:

[0034] When in use, the carrying plate 332 on the lifting mechanism 33 descends to the lower limit position, and the empty winding roller 22 is pushed into the middle from the left or right side of the winding frame 11 along the guide walking groove 1111, so that the outer end roller shaft of the winding roller 22 is located above the bearing holder 333, and then the driving motor 337 is started, and the two lifting screw rods 331 are driven to rotate synchronously through the driving shaft 336, the two driving bevel gears 335, and the two transmission bevel gears 334, so that the two carrying plates 332 rise synchronously, and after the outer end roller shaft of the winding roller 22 is clamped into the two bearing holders 333, it continues to be lifted to the upper limit position, so that the transmission friction roller 443 on the outer end roller shaft of the winding roller 22 contacts and abuts against the driving friction roller 441; in the initial state, the support plate 551 is located on the outside, and the support plate 551 is not The interference carrier plate 332 is lifted and lowered; after the carrier plate 332 rises to the upper limit position, the support plate 551 is pushed to slide in the middle so that the upper plate surface of the support plate 551 fits with the bottom of the carrier plate 332; the winding motor 442 is started, and the friction roller 441 and the transmission friction roller 443 are driven to drive the winding roller 22 to rotate to implement winding. After the winding is completed, the cable is cut, and then the support plate 551 is reset, and the drive motor 337 is started again to reverse, and the lifting screw rod 331 is driven to rotate in the opposite direction, so that the carrier plate 332 drives the winding roller 22 equipped with the cable to descend to the bottom frame plate 111, so that the two supporting side plates on the winding roller 22 are located in the guide walking groove 1111, and finally, the staff can push it out from the left or right side along the guide walking groove 1111.
