AI Technical Summary
Traditional cable sheath cooling methods lead to rapid shrinkage, cracking, and plastic deformation of the sheath, and high-temperature cables are prone to deformation when in contact with pulleys.
Design a cable sheath surface cooling device, which uses a pre-cooling device for atomized spray cooling, combined with upper and lower rollers for shaping and cooling, to avoid direct contact with pulleys.
This reduces the plastic deformation of the cable sheath, ensuring that the cable is not subjected to compressive deformation during the cooling and shaping process, thereby improving the cooling effect and shaping quality.

[0002] In the cable production process, the cable sheath needs to be cooled and shaped after extrusion molding. The traditional cooling method mainly uses water tank immersion cooling. However, these traditional cooling methods have the following disadvantages:

[0025] Referring to Figure 1 and Figure 2 The cable sheath surface cooling device shown in the figure comprises a water cooling tank 1, a water inlet pipe 2, an overflow pipe 3 and a water outlet pipe 4 are installed outside the water cooling tank 1, the height of the overflow pipe 3 is lower than that of the water inlet pipe 2, a valve 41 is installed on the water outlet pipe 4, and the water outlet pipe 4 is installed at a position close to the bottom of the water cooling tank 1, so as to facilitate emptying the water in the water cooling tank 1 and cleaning the water cooling tank. A first shaft (not shown) is arranged at a position close to both ends in the inside of the water cooling tank 1, an upper roller body 5 is rotatably installed on the first shaft, rotation is supported by a bearing, and part of the upper roller body 5 is exposed to the outside of the water cooling tank 1. A plurality of second shafts (not shown) are arranged in the inside of the water cooling tank 1, a lower roller body 6 is rotatably installed on the second shaft, rotation is supported by a bearing, and the height of the lower roller body 6 is lower than that of the overflow pipe 3. A recess 121 is processed at the top of the water cooling tank 1, a precooling device 7 is installed at the recess 121, and the cooled cable enters from the precooling device 7.
[0026] In the above technical solution, the extrusion molded cable sheath first enters the precooling device 7, is pre-cooled by atomized water vapor, and then enters the water cooling tank through the transition of the upper roller body 5.
[0027] The advantage of such design is that it avoids plastic deformation of the cable caused by direct contact with the upper roller body.
[0028] During the cooling period, the water inlet pipe is kept in the water inlet state all the time, ensuring that the water temperature of the cooling water is maintained at 30-50 degrees Celsius.
[0029] Referring to Figure 1 As shown, the surfaces of the upper roller body 5 and the lower roller body 6 are both provided with annular grooves 8, and the cooled cable is positioned in the annular grooves 8.
[0030] The annular grooves 8 are used to position the movement of the cable, ensuring the accurate position of the cable.
[0031] Referring to Figure 2 As shown, the pre-cooling device 7 includes a water tank 71, two upper and lower notches (not shown) are formed on the side of the water tank 71, and an upper water plate 72 and a lower water plate 73 are welded at the notches, the inner cavities of the upper water plate 72 and the lower water plate 73 are both in communication with the water tank 71, the cooled cable passes between the upper water plate 72 and the lower water plate 73, and atomizing nozzles 74 are provided on the corresponding surfaces of the upper water plate 72 and the lower water plate 73; a pump water pipe 75 is connected to the outside of the water tank 71, a water pump (not shown) is installed at the end of the pump water pipe 75, and the lower water plate 73 is fixed in the notch.
[0032] In the above technical solution, the cable passes between the upper water plate 72 and the lower water plate 73, and the atomized water vapor sprayed by the atomizing nozzles 74 contacts the surface of the cable to complete the pre-cooling of the sheath.
[0033] Due to the limited space, the atomized water vapor sprayed upward condenses after contacting the upper water plate 72, and the atomized water vapor sprayed downward condenses after contacting the lower water plate 73.
[0034] Referring to Figure 2 As shown, the upper surface of the lower water plate 72 is a slope 772 that inclines downward toward the water cooling tank 1, and a water baffle 773 is provided on the side of the lower water plate 72.

[0036] Referring to Figure 2 As shown, the upper and lower atomizing nozzles 74 are opposite to each other, and the positions of the atomizing nozzles correspond to the annular grooves.
[0037] Such opposite layout can make the contact efficiency of the atomized water vapor with the cable higher.
[0038] Referring to Figure 1As shown, a frame plate 133 is arranged in the middle of the water cooling tank 1, and multiple fans 134 are installed on the surface of the frame plate 133, with the fans 134 blowing air downwards.
[0039] Fan 134 can cool the cooling water in water-cooled tank 1.
