Description

Technical Field

[0002] In the processing and production process of highly flame-retardant radiation cross-linked low-smoke halogen-free cable insulation layer, it is usually necessary to cool the insulation material by water cooling. The patent with announcement number CN212303193U discloses a highly flame-retardant radiation cross-linked low-smoke halogen-free insulation material cooling equipment for cable production. The equipment is provided with a first pulley and a second pulley so that the cable can smoothly enter the water in the second cooling box for cooling; and by installing a water pump in the first cooling box and providing a second water outlet pipe at the bottom of the second cooling box, the recycling of cooling water is realized; in addition, a wastewater filter box is configured at the bottom of the first cooling box, and a first filter plate and a second filter plate are installed inside to achieve multi-stage filtration of cooling water, ensure clean water quality, and reduce environmental pollution.

[0003] Nevertheless, the above-mentioned highly flame-retardant radiation cross-linked low-smoke halogen-free cable insulation material cooling device still has some problems in practical application. Specifically, when the insulation material passes through the first cooling box, due to its relatively fixed travel path, it is easy to cause the water temperature around the insulation material to rise rapidly, thereby affecting the cooling effect. In order to obtain a better cooling effect, the moving speed of the insulation material has to be reduced, but this will directly affect the production efficiency. In view of this, the utility model aims to provide a highly flame-retardant radiation cross-linked low-smoke halogen-free cable insulation layer cooling device with better cooling effect.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figures 1 to 3According to an embodiment of the utility model, a radiation cross-linked cable insulation layer cooling device is provided, which comprises a cooling water trough 1, a pressing component 2 and a driving component 3, wherein the cooling water trough 1 is suitable for containing cooling water; the pressing component 2 is configured to press the cable insulation layer 4 into the cooling water in the cooling water trough 1; the driving component 3 is configured to drive the pressing component 2 to rotate back and forth so that the cable insulation layer 4 swings back and forth in the cooling water.

[0022] In the radiation cross-linked cable insulation layer cooling device with the above structure, when the cable insulation layer 4 passes through the cooling water tank 1, the pressing component 2 is pressed into the cooling water to achieve water cooling. At this time, the pressing component 2 is driven to rotate back and forth by the driving component 3, thereby driving the cable insulation layer 4 to swing back and forth, constantly changing the travel path of the cable insulation layer 4. At the same time, the reciprocating rotation of the pressing component 2 increases the flow of cooling water. In this case, the cooling effect of the cable insulation layer 4 can be ensured without reducing the moving speed of the cable insulation layer 4.

[0023] In this exemplary embodiment, the pressing component 2 includes a pressing plate 20, a fixing plate 21, a connecting shaft 22 and a first pulley 23. The fixing plate 21 is fixedly arranged on the top of the cooling water tank 1. The pressing plate 20 is arranged in the cooling water tank 1. One end of the connecting shaft 22 is fixed to the pressing plate 20, and the other end of the connecting shaft 22 is rotatably connected to the fixing plate 21. A pair of first pulleys 23 are arranged at the bottom of the pressing plate 20, and the cable insulation layer 4 passes through the grooves of the wheel surfaces of the two first pulleys 23. In this way, when the cable insulation layer 4 passes through the pressing component 2, it will be restricted in the groove of the first pulley 23, so that the cable insulation layer 4 will not be separated from the pressing plate 20 of the pressing component 2. At the same time, the setting of the first pulley 23 can also reduce the resistance of the cable insulation layer 4 when passing through the pressing component 2, so that the cable insulation layer 4 moves more smoothly. In addition, by using two spaced first pulleys 23 to support the cable insulation layer 4, the length of the cable insulation layer 4 in the cooling water can be increased, thereby extending the path of the cable insulation layer 4 in the cooling water and further improving the cooling effect. Of course, as long as the cable insulation layer 4 can be pressed into the cooling water of the cold water tank and the movement of the cable insulation layer 4 is not restricted, there is no particular limitation on the specific structural form of the pressing member 2 .

[0024] In this exemplary embodiment, the pressing component 2 further includes a limiting roller 24, and a pair of limiting rollers 24 are respectively arranged at the positions corresponding to the two first pulleys 23 at the bottom of the pressing plate 20, and the limiting rollers 24 are rotatably connected to the pressing plate 20. The limiting rollers 24 can further limit the position of the cable insulation layer 4 on the pressing plate 20, so that during the swinging process of the pressing component 2, the cable insulation layer 4 is not easy to be separated from the groove of the first pulley 23, ensuring that the cable insulation layer 4 moves smoothly in the cooling water.

[0025] In order to realize the reciprocating rotation of the pressing component 2, in the present exemplary embodiment, the driving component 3 includes a motor 30, a reciprocating screw 31, a slider 32, a rotating shaft 33 and a slide bar 34. The housing of the motor 30 is fixed on the fixed plate 21, the reciprocating screw 31 is fixed to the output shaft of the motor 30, the slider 32 is threadedly connected to the reciprocating screw 31, the rotating shaft 33 is rotatably connected to the slider 32, one end of the slide bar 34 is fixed to the connecting shaft 22, and the other end of the slide bar 34 is movable through the rotating shaft 33. When it is necessary to drive the pressing component 2 to reciprocate, the motor 30 is started, and the motor 30 drives the reciprocating screw 31 to rotate, so that the slider 32 and the rotating shaft 33 reciprocate on the reciprocating screw 31, the rotating shaft 33 rotates on the slider 32, and the slide bar 34 slides on the rotating shaft 33 and swings around the axis of the connecting shaft 22. When the slide bar 34 swings, it drives the connecting shaft 22 to reciprocate, and finally realizes the reciprocating rotation of the pressing component 2. Of course, as long as it can drive the pressing component 2 to rotate back and forth, there is no particular limitation on the specific structural form of the driving component 3.

[0026] In this exemplary embodiment, a second pulley 5 is provided on each of the front and rear sides of the top of the cooling water trough 1, and the cable insulation layer 4 passes through the grooves on the wheel surfaces of the two second pulleys 5. By providing a second pulley 5 on each side of the top opening of the cooling water trough 1, the cable insulation layer 4 rolls in contact with the second pulley 5 when passing through the cooling water trough 1, thereby avoiding direct sliding contact between the cable insulation layer 4 and the cooling water trough 1, and reducing the wear of the cable insulation layer 4 during the cooling process.

[0027] In this exemplary embodiment, the bottom of the cooling water tank 1 is fixedly connected to the bottom plate 6 through the connecting column 7, and a circulating cooling assembly 8 is arranged between the bottom plate 6 and the cooling water tank 1. The circulating cooling assembly 8 includes a fan 80, a cooling pipe 81, a return pipe 82 and a water pump 83. The cooling pipe 81 is spiral, one end of the cooling pipe 81 is connected to the left side of the bottom of the cooling water tank 1, and the other end of the cooling pipe 81 is connected to the water inlet end of the water pump 83. The water outlet end of the water pump 83 is connected to the right side of the bottom of the cooling water tank 1 through the return pipe 82, and the exhaust side of the fan 80 is arranged opposite to the cooling pipe 81. By arranging the circulating cooling assembly 8, during the cooling process, the cooling water flows in the circulation channel formed by the cooling water tank 1, the cooling pipe 81, the water pump 83 and the return pipe 82, and the fan 80 performs air cooling on the cooling pipe 81, so that the circulating flow cooling of the cooling water can be achieved, so that the water in the cooling water tank 1 is kept at a relatively low temperature, thereby improving the cooling effect of the cable insulation layer 4.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
