DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0024] Example 1

[0025] A molding cooling device for cable production, such as Figure 1-Figure 4 As shown, it includes a box body 1 and guide rollers 2; the box body 1 is rotatably connected to a plurality of guide rollers 2;

[0026] It also includes a partition 4, a connecting pipe 101, a water spray plate 102, a circulation pipe 103, a water pump 104, a hollow pipe 105 and a baffle 107; the box body 1 is tilted with the left side lower and the right side higher; the box body 1 is fixedly connected with the partition 4, and a water delivery trough 12 is formed between the partition 4 and the box body 1; the box body 1 is connected with a plurality of pipe groups, and the pipe groups are located between two adjacent guide rollers 2; each pipe group is composed of two connecting pipes 101; all the connecting pipes 101 in the same pipe group are connected to a hollow water spray plate 102; Each water spray plate 102 is provided with a plurality of water spray holes 1021; a water leakage groove 11 is provided at the left end of the box body 1; a circulation pipe 103 is fixedly connected to the box body 1, and one end of the circulation pipe 103 is connected to the water leakage groove 11, and the other end of the circulation pipe 103 is connected to the box body 1; a water pump 104 is fixedly connected to the box body 1, and the water pump 104 is connected to the circulation pipe 103; a hollow pipe 105 is fixedly connected to the box body 1, and the hollow pipe 105 is connected to the water delivery groove 12; a baffle 107 is connected to the left end of the box body 1, and the baffle 107 is fixedly connected to the partition 4.

[0027] The water spray plate 102 is arranged in an arc shape, so that the water spray holes 1021 are distributed in an arc shape, increasing the gap between the water spray holes 1021 and the cable body 3, and thus when the water spray plate 102 is close to the cable body 3, the cable body 3 is prevented from covering the water spray holes 1021, thereby reducing the water spraying effect.

[0028] It also includes a siphon tube 106 ; each connecting pipe 101 is connected to a siphon tube 106 that is arranged obliquely, and the siphon tube 106 is located above the partition plate 4 .

[0029] It also includes a telescopic column 13; the telescopic ends of several telescopic columns 13 are fixedly connected to the box body 1, and then the height of the box body 1 is adjusted by the telescopic column 13 to adapt to cable production lines of different heights.

[0030] It also includes a limiting plate 1011; the baffle 107 is detachably connected to the limiting plate 1011; the limiting plate 1011 is provided with a plurality of grooves 1071. When the thick cable is cooled, the limiting plate 1011 is disassembled and replaced so that the number of the grooves 1071 corresponds to the thick cable, thereby improving the adaptability of the limiting plate 1011.

[0031] The left end of the box body 1 is fixedly connected to the end plate 14, which blocks the water falling from the baffle 107 and the limit plate 1011 to prevent the water from splashing around when it falls into the leaking trough 11.

[0032] Each guide roller 2 is provided with a plurality of water inlet holes 21. Since the guide roller 2 is in contact with the high-temperature cable body 3 at all times, the temperature of the guide roller 2 is relatively high. By providing the water inlet holes 21, cooling water is allowed to enter the guide roller 2 from the water inlet holes 21 to cool the guide roller 2.

[0033] The partition 4 is made of heat-insulating material to prevent the heat in the cooling water on the upper side of the partition 4 from being transferred to the cooling water in the water delivery trough 12 , thereby improving the cooling efficiency of the cooling water in the water delivery trough 12 on the cable body 3 .

[0034] When in use, first connect the external pump to the hollow tube 105, then start the water pump 104 to add cooling water into the box 1 through the circulation tube 103 until the water level 1001 submerges the guide roller by 25-60 cm, then manually use tools to put one end of the cable body 3 composed of multiple copper cores and extruded high-temperature rubber layers onto the guide roller 2 in the box 1, and pull it to the right to fix it on the external conveyor. It should be noted that at this time, the cable body 3 is composed of a copper core and an extruded high-temperature rubber layer; Subsequently, the external conveyor is controlled to convey the multiple cable bodies 3 to the right in the box 1 under the guidance of the guide roller 2, and then the cooling water cable bodies 3 in the box 1 are conveyed to the right, and the cooling water flowing to the left in the box 1 cools the cable bodies 3. The water pump 104 is controlled to allow the cooling water to enter the box 1 and then flow back through the circulation pipe 103, so that the cooling water in the box 1 is in a state of flowing to the left. Since the box 1 is inclined with the left lower and the right higher, the cooling water in the box 1 is in a state of being higher on the left and lower on the right, thereby preventing the cooling water from flowing out from the right end of the box 1.

[0035] At the same time, the external pump is controlled to start, and the cooling water is input into the water tank 12 through the hollow pipe 105, so that high-pressure cooling water is formed in the water tank 12. Then, the high-pressure cooling water in the water tank 12 passes upward through the connecting pipe 101 and enters the water spray plate 102, and finally sprays upward from the water spray hole 1021, so that the cooling water sprays and cools the cable body 3 in the middle, thereby improving the cooling efficiency of the cable body 3 in the middle.

[0036] Since the density of hot water is smaller and the density of cold water is larger, the hot water moves upward while the cold water sinks, so that the cold water in the box body 1 is distributed in the bottom area near the partition 4. Therefore, the cold water in the bottom area near the partition 4 is pumped upward through the siphon tube 106 under the action of the water pressure difference, passes through the connecting pipe 101 and enters the water spray plate 102, and finally sprays upward from the water spray hole 1021, so that the temperature distribution of the cooling water in the box body 1 is relatively uniform, and the cooling efficiency of the cable body 3 is further improved.

[0037] As the cable body 3 moves to the right, the high-temperature rubber layer extruded from the surface of the cable body 3 will form an oil film on the surface of the water flow after just contacting the cooling water, thereby contaminating the cooling water. Therefore, in the process of the cooling water flowing to the left in the box body 1, the left end of the flow of the cooling water is blocked by the baffle 107 and the limit plate 1011, so that the cooling water in the box body 1 passes through the baffle 107 and the limit plate 1011 and flows down from the leakage groove 11 into the circulation pipe 103 in a waterfall shape, so that the cooling water can take away the oil film in time, so that the cooling water can remain in a relatively clean state.

[0038] Since the end of the cable body 3 will be slightly bent when entering the box body 1, and thus the cable body 3 will bend after cooling and shaping, therefore, a groove 1071 is provided on the limiting plate 1011, so that after entering the box body 1, the cable body 3 enters the box body 1 through the groove 1071 and contacts the cooling water, so that the cable body 3 is in a relatively straight state and contacts the cooling water in the box body 1, so that the cable body 3 remains in a straight state for cooling and shaping.

[0039] Example 2

[0040] On the basis of Example 1, Figure 1-Figure 3 and Figure 5 As shown, it also includes a cover plate 108 and a round tube 109 ; the left end of the box body 1 is fixedly connected to the cover plate 108 ; the cover plate 108 is fixedly connected to the round tube 109 .

[0041] It also includes a camera 1010 ; at least four cameras 1010 are fixedly connected to the box body 1 .

[0042] The external suction pump is connected to the circular tube 109. When the thicker cable body 3 is cooled, the surface area of ​​the cooling water in contact with the cable body 3 is large, so that the temperature of the cooling water just in contact with the cable body 3 is close to its boiling point. Then part of the cooling water at the left end of the box 1 will evaporate into steam. The drifting steam will bring potential safety hazards to the electrical equipment in the production workshop. Therefore, during the cooling process, the external suction pump is controlled to start, and the circular tube 109 is used to suck the upper left end of the box 1 to promptly remove the generated steam, thereby improving production safety.

[0043] During the cooling process of the cable body 3, the length of the box 1 is usually long, so that personnel cannot always pay attention to the state changes of the cable body 3. Therefore, a camera 1010 is set on the box 1 to monitor the state of the cable body 3 in real time, so that the cable body 3 always remains straight.

[0044] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
