Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a flame-retardant and durable cable. Background Art

[0002] A flame-retardant power cable refers to a cable that, under specified test conditions, when the specimen is burned and the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or afterglow can self-extinguish within a limited time. Its fundamental characteristic is that it may be damaged and unable to operate in case of a fire, but it can prevent the spread of the fire. Generally speaking, in case of a fire in the wire, the combustion can be limited to a local area without spreading, protecting various other devices and avoiding greater losses.

[0003] Existing flame-retardant and durable cables have relatively good flame retardancy, but their mechanical properties are relatively poor, they are prone to deformation, and all the cable cores are wound together, which will cause the heat generated by them to affect each other, resulting in a low service life; and in the last step of processing the cable, a protective layer is coated on the surface of the cable through a coating machine, but the existing coating machine only coats one side of the cable, which is not convenient for coating both sides of the cable synchronously. Summary of the Invention

[0004] The purpose of the present invention is to provide a flame-retardant and durable cable, and solve the following technical problems: existing flame-retardant and durable cables have relatively good flame retardancy, but their mechanical properties are relatively poor, they are prone to deformation, and all the cable cores are wound together, which will cause the heat generated by them to affect each other, resulting in a low service life; and in the last step of processing the cable, a protective layer is coated on the surface of the cable through a coating machine, but the existing coating machine only coats one side of the cable, which is not convenient for coating both sides of the cable synchronously.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A flame-retardant and durable cable includes an insulating sleeve I. Inside the insulating sleeve I, a cross-shaped support frame is provided. The support frame divides the insulating sleeve I into four equal regions. In each region, a wire core I is provided. The wire core I is coated with an insulating sleeve II. The insulating sleeve II is filled with a filler. At the center of the support frame, a wire core II is provided. The wire core II is coated with an insulating layer. The insulating sleeve I is coated with an armor layer. The armor layer is coated with an anti-corrosion sleeve. A mixed coating is coated on the anti-corrosion sleeve through a coating machine.

[0007] As a further solution of the present invention: The mixed coating is prepared by mixing a flame-retardant coating and an epoxy resin coating.

[0013] Step 3: The cable passes through the trapezoidal sleeve. Drive the lead screw to drive the trapezoidal sleeve to move from right to left. Then, during the winding process, it will move from right to left for winding. When the trapezoidal sleeve reaches the leftmost side, the abutting rod contacts the inclined block, and pushes the rubber inclined block to clamp the cable. At this time, the cable is also wound into a bundle on the winding disc, and it can be cut off, remove the winding disc, and continue to work.

[0014] As a further solution of the present invention: The coating machine includes a frame. Both sides of the frame are rotatably connected with screw rods.

The first tapered block 18 and the second tapered block 19 are adapted to the winding disc 4;

[0038] A top plate 3 is fixedly installed on the top of the frame 1. A rotary motor is fixedly installed on the top plate 3. A movable arc plate 32 is fixedly installed on the top of the rotary motor. Both ends of the movable arc plate 32 are rotatably connected with guide wheels 31. A plurality of vertical guide rollers 33 are equidistantly arranged on the movable arc plate 32. Two parallel horizontal guide rollers 34 are arranged on one side of each vertical guide roller 33. A coating barrel 35 is arranged on one side of one of the guide wheels 31. The cable passes through the coating barrel 35 and is wound on the winding disc 4. By driving the movable arc plate 32 to rotate, it is convenient to adjust the tightness of the cable transmission.

[0039] The formed cable is sequentially wound around the guide wheel 31, the vertical guide roller 33, the horizontal guide roller 34 and the guide wheel 31, passes through the coating barrel 35 and the trapezoidal sleeve 117, and then is wound on the winding disc 4.

[0040] Place the winding disc 4 on the bottom plate 2. One end of the winding disc 4 is inserted onto the second tapered block 19. Then rotate the crank 15 to drive the threaded rod 17 to rotate. The threaded rod 17 pushes the first tapered block 18 to insert into the other end of the winding disc 4 to fix the winding disc 4. Then drive the motor to drive the first gear 110 to rotate. The first gear 110 drives the second gear 111 to rotate through the chain. The first gear 110 and the second gear 111 drive the threaded rod 17 to rotate, thereby driving the lifting frame 13 to rise. And drive the first motor 14 to drive the winding disc 4 to rotate for winding. During the winding process, the formed cable passes through the coating barrel 35, and the coating barrel 35 coats the surface of the cable to form a mixed coating 700.

[0041] On the inner walls of the top and bottom of the coating barrel 35, conical sleeves 351 are fixedly installed. The two conical sleeves 351 are symmetrically arranged, and there is a gap between the two conical sleeves 351. An annular guide rail 352 is arranged on the inner wall of the coating barrel 35.

The threaded rod 17 pushes the first tapered block 18 to insert into the other end of the winding disc 4 to fix the winding disc 4. Then pass the formed cable around the guide wheel 31, the vertical guide roller 33, the horizontal guide roller 34 and the guide wheel 31 in sequence, pass through the coating barrel 35 and the trapezoidal sleeve 117, and then wind it on the winding disc 4.

[0048] Then drive the motor to drive the first gear 110 to rotate. The first gear 110 drives the second gear 111 to rotate through a chain. The first gear 110 and the second gear 111 drive the threaded rod 17 to rotate, thereby driving the lifting frame 13 to rise. And drive the motor 14 to drive the winding disc 4 to rotate for winding. During the winding process, pass the formed cable through the coating barrel 35, and the coating barrel 35 coats the surface of the cable.

[0049] Pass the formed cable through the tapered sleeve 351. Start the driving motor to rotate. The driving motor drives the driving wheel to slide on the annular guide rail 352, thereby driving the two movable spray heads 353 to rotate and spray and coat the surface of the formed cable. Through the upper and lower tapered sleeves 351, on the one hand, it plays a guiding role, and on the other hand, it can avoid the splashing of excess paint and avoid environmental pollution. At the same time, through the setting of the tapered sleeve 351 on the favorite side, it is convenient to scrape the paint on the formed cable more evenly.

[0050] Pass the coated cable through the trapezoidal sleeve 117, and drive the lead screw 112 to drive the trapezoidal sleeve 117 to move from right to left. During the winding process, it will move from right to left for winding, making the winding more beautiful and dense. When the trapezoidal sleeve 117 reaches the leftmost position, the abutting rod 114 contacts the inclined block 113, and the rubber inclined block 116 is pushed to clamp the cable. At this time, the cable has been wound into a bundle on the winding disc 4, so it can be cut off, the winding disc 4 can be disassembled, and the work can continue.
