[0015] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.
[0016] Please refer to Figures 1-5 A kind of high-efficiency coating device of flame-retardant high-temperature rope, the technical scheme presented in the utility model, including rack 1, rack 1 is fixedly provided with unwinding mechanism 2 and drying mechanism 3, rack 1 is fixedly provided with dip coating box 4;First-stage penetration mechanism, it includes two first extrusion rollers 11 rotationally arranged in dip coating box 4, the interval of two first extrusion rollers 11 is 1.2 times of the diameter of rope body;Second-stage penetration mechanism, it includes two second extrusion rollers 12 rotationally arranged in dip coating box 4, the interval of two second extrusion rollers 12 is same with the diameter of rope body;Third-stage penetration mechanism, it includes two third extrusion rollers 13 rotationally arranged in dip coating box 4, the interval of two third extrusion rollers 13 is 0.8 times of the diameter of rope body;Dip coating box 4 is fixedly arranged between unwinding mechanism 2 and drying mechanism 3 of rack 1, first extrusion roller 11, second extrusion roller 12, third extrusion roller 13 are all in liquid in dip coating box 4, flame-retardant high-temperature rope body is first unwound through unwinding mechanism 2, then passes between two first extrusion rollers 11, then passes between two second extrusion rollers 12, finally passes between two third extrusion rollers 13 to complete dip coating, then passes from drying mechanism 3 to complete drying, when flame-retardant high-temperature rope is in the middle of advancing and passes between two first extrusion rollers 11, is slightly extruded the surface of rope body by two first extrusion rollers 11, so that surface layer fiber gap is reduced, and part of air is discharged, when flame-retardant high-temperature rope leaves first extrusion roller 11, the elastic resilience of rope body, fiber gap restores and generates micro suction, and dip coating liquid is absorbed into shallow layer gap, when flame-retardant high-temperature rope passes two second extrusion rollers 12, the force of two second extrusion rollers 12 extruding rope body increases, and middle layer limiting gap is compressed, and residual air is discharged, when flame-retardant high-temperature rope leaves second extrusion roller 12, middle layer fiber resilience generates stronger suction, and dip coating liquid is further penetrated into the weaving structure of flame-retardant high-temperature rope, when flame-retardant high-temperature rope passes third extrusion roller 13, extrusion degree reaches maximum, and flame-retardant high-temperature rope deep layer fiber gap is completely opened, when leaving third extrusion roller 13, the elastic recovery of flame-retardant high-temperature rope further absorbs dip coating liquid, and through multistage penetration, the penetration rate of dip coating liquid can be greatly increased.
[0017] Specifically, the first, second and third penetrating mechanisms are arranged in a V shape towards the inside of the dip coating; as shown in the figure, the first, second and third penetrating mechanisms are arranged in an inverted V shape, and the secondary arrangement can increase the moving path of the fire-retardant high-temperature rope in the dip coating box 4, thereby increasing the contact time of the rope body with the coating liquid and further increasing the penetration efficiency. Figure 3
[0018] Specifically, the middle part of each first, second and third extrusion roller 11, 12 and 13 is fixedly provided with a rubber sleeve 20, and the two ends of each rubber sleeve 20 are fixedly provided with a limiting block 19; the fire-retardant high-temperature rope passes through the corresponding rubber sleeves 20, and the limiting block 19 and the rubber sleeve 20 are made of oil-resistant rubber material with a Shore hardness of 60°, which can balance the elasticity and wear resistance. When the first, second and third extrusion rollers 11, 12 and 13 rotate, the rubber sleeves 20 extrude the fire-retardant high-temperature rope, while avoiding damage to the fire-retardant high-temperature rope. During the movement of the fire-retardant high-temperature rope, each limiting block 19 can prevent the rope body from shifting off the rubber sleeve 20.
[0019] Specifically, two spiral grooves 18 are formed on each first, second and third extrusion roller 11, 12 and 13, and the spiral direction of each spiral groove 18 is towards the rubber sleeve 20; the rubber sleeve 20 is fixedly arranged at the middle position of the first, second and third extrusion rollers 11, 12 and 13, and the spiral grooves 18 are located on both sides of the rubber sleeve 20.

When each spiral groove 18 rotates, it can stir the liquid in the dip coating box 4 to prevent the liquid from stratifying due to sedimentation. At the same time, since the spiral grooves 18 are towards the rubber sleeve 20, part of the liquid can be pushed towards the rubber sleeve 20 when the spiral grooves 18 rotate, thereby guiding the liquid to continuously collide with the rope body and increasing the penetration ability of the liquid.
[0020] Specifically, two limiting rods 7 are rotatably arranged on the side of the dip coating box 4 close to the unwinding mechanism 2; the two limiting rods 7 are rotatably arranged at the middle position of the side wall of the dip coating box 4, and the middle position of the two limiting rods 7 is aligned with the middle position of the rubber sleeve 20. The distance between the two limiting rods 7 is slightly greater than the diameter of the fire-retardant high-temperature rope. The two limiting rods 7 can align the fire-retardant high-temperature rope passing through the dip coating box 4 from the unwinding device, thereby preventing the rope body from shifting.
[0021] Specifically, two liquid removing rollers 8 are rotatably arranged in the dip coating box 4, and two scrapers 9 are fixedly arranged in the dip coating box 4; when the fire-retardant high-temperature rope after dip coating comes out of the dip coating liquid, it will pass through the two liquid removing rollers 8, and the excess liquid on the fire-retardant high-temperature rope is squeezed out through the extrusion of the two liquid removing rollers 8, so as to avoid liquid waste and facilitate subsequent drying; the scrapers 9 are located on both sides of the fire-retardant high-temperature rope close to the first extrusion roller 11, and the scrapers 9 abut against the liquid removing rollers 8 one by one, the liquid adhered to the liquid removing rollers 8 is scraped off by the scrapers 9, and the liquid flows into the dip coating box 4 again.
