Description

TECHNICAL FIELD

[0001] The utility model relates to cable processing field, concretely relates to a novel device that improves surface quality defect of umbilical cable electric unit insulating sheath. BACKGROUND

[0002] In the production process of PE insulation and sheath of umbilical cable electric unit, the cooling link is one of the key steps to ensure product quality. However, the existing cooling device and cooling method have many problems, which seriously affect the surface quality of the product. In the cooling process, the cooling water flows in the cooling tank and flows to the recovery device, which will produce the phenomenon of splashing water. Once these splashing water contacts the surface of the insulation and sheath, it will cause the local cooling speed to be too fast. Due to the inconsistent cooling speed of different parts, the sheath surface will have different shrinkage degrees, thus forming traces similar to water drop lines and producing pits, which greatly damages the surface quality of the insulation and sheath. This quality problem will lead to customer complaints, seriously affecting the market reputation of the product and the economic benefits of the enterprise. In order to solve the above-mentioned quality problem caused by water drop lines in the cooling process, the industry has tried some traditional solutions. One common method is to control the cooling process, that is, to use warm water for cooling in the first-stage cooling water tank. The principle is to reduce the difference in cooling speed by increasing the water temperature, thereby reducing the surface quality problem caused by the local cooling speed being too fast. Another method is to add laundry detergent to the cooling water to reduce the cooling water flow rate through the foaming action of the laundry detergent to prevent water splashing. However, these traditional solutions have obvious shortcomings. First of all, the above-mentioned methods often require reducing the production speed, which greatly affects the production efficiency and reduces the production capacity of the enterprise. Secondly, when reducing the cooling water flow rate, the water surface will drop, and for large-sized core wires, the cooling will be uneven, and even the cooling water on the surface of the core wire may be too little, causing the surface of the core wire to be exposed, thereby affecting the cooling effect and quality of the product. Thirdly, the warm water cooling method requires an additional heating system in the first-stage cooling water tank to heat the water, which not only increases the equipment cost but also increases energy consumption, resulting in rising production costs. Finally, when using laundry detergent, it is difficult to control the amount of laundry detergent. If the amount of laundry detergent is too small, it cannot achieve the expected effect of preventing water splashing. If the amount is too large, it will cause excessive foaming, and the excessive foam will accumulate at the die opening, causing lines on the surface of the core wire, further affecting the surface quality of the product. SUMMARY

[0003] The problem to be solved by the utility model is to provide a novel device for improving the surface quality defect of the insulating sheath of the umbilical cable electric unit to prevent the water splashing onto the surface of the insulating sheath of the umbilical cable electric unit to be cooled, causing surface quality problems of the product.

[0004] The utility model discloses a technical scheme that solves the above problems, which is a novel device for improving surface quality defects of umbilical cable electrical unit insulating sheath, comprising: a liquid return groove; a cooling tank containing cooling liquid; a separation support plate arranged between the liquid return groove and the cooling tank, the upper end of the separation support plate being provided with a cooling port, the cooling liquid in the cooling tank being able to flow out of the cooling port and fall into the liquid return groove under the action of gravity, the cooling port being used for allowing the umbilical cable electrical unit insulating sheath to be cooled to pass through and enter the cooling liquid in the cooling tank; and a splash-proof mechanism arranged between the liquid return groove and the umbilical cable electrical unit insulating sheath to be cooled, the splash-proof mechanism being used for absorbing splashes generated due to the cooling liquid falling from the cooling port into the liquid return groove to prevent the splashes from splashing onto the surface of the umbilical cable electrical unit insulating sheath to be cooled.

[0005] When the umbilical cable electrical unit insulating sheath is cooled, the cooling is mainly achieved by means of the cooling water in the cooling tank. By accurately concentrating the position of the cooling water flowing out at the cooling port, the cooling liquid can be effectively drained in an orderly manner, avoiding many problems caused by the disordered flow of the cooling water. Moreover, the faster water circulation at this position is beneficial to the rapid solidification of the surface of the umbilical cable electrical unit insulating sheath and improves the consistency of the surface. However, when the cooling liquid falls from the cooling port into the liquid return groove, splashes are inevitably generated. If these splashes splash onto the surface of the umbilical cable electrical unit insulating sheath to be cooled, it is very likely to cause serious quality problems. Because during the cooling process, if the part contacting the splashes is partially solidified in advance, the uniformity of the whole will be damaged, thereby causing surface quality problems and affecting the performance and service life of the product. In order to avoid such situations, the splash-proof mechanism is arranged between the liquid return groove and the umbilical cable electrical unit insulating sheath to be cooled, which can efficiently absorb the splashes generated due to the cooling liquid falling from the cooling port into the liquid return groove, ensure that the umbilical cable electrical unit insulating sheath to be cooled remains dry during the cooling process and is not disturbed by the splashes, thereby guaranteeing the surface quality of the product.

[0006] Further, the splash-proof mechanism comprises an absorbing plate and an adjusting seat, the absorbing plate is located between the bottom surface of the liquid return groove and the umbilical cable electrical unit insulating sheath to be cooled, and a water passing hole is formed in the side of the absorbing plate facing the cooling port for allowing the cooling liquid flowing out of the cooling port to fall to the bottom of the liquid return groove, and the absorbing plate is fixed to the bottom of the liquid return groove through the adjusting seat.

[0007] The absorbing plate is located between the liquid return groove and the insulating sheath of the umbilical cable electrical unit, and the water hole thereof allows the cooling liquid to fall into the liquid return groove, so that the orderly cooling liquid directly falls into the liquid return groove. When the orderly cooling liquid splashes when contacting the bottom of the liquid return groove, the splash is blocked and absorbed by the bottom of the absorbing plate, effectively preventing the splash from splashing onto the insulating sheath, thereby ensuring the product quality. The absorbing plate is fixed by the adjusting seat, and has flexible adjustment performance. The height of the absorbing plate can be adjusted according to the cooling requirements of insulating sheaths of different specifications, thereby improving the versatility of the height lifting device.

[0008] Further, the absorbing plate has a structure of two layers of spring meshes sandwiching foam cotton.

[0009] The foam cotton has excellent water absorption and buffering performance, and can quickly absorb a large amount of splash when the cooling liquid falls from the cooling port and splashes into the liquid return groove, thereby reducing the impact force of the splash. The two layers of spring meshes not only provide stable support for the foam cotton to prevent it from deforming and shifting under the impact of water flow, but also further block larger water droplets from splashing. In addition, the elastic property of the spring mesh can provide a secondary buffering effect for the splash. The combination of the three greatly enhances the ability of the absorbing plate to block and absorb the splash, thereby ensuring that the insulating sheath of the umbilical cable electrical unit is not disturbed by the splash during the cooling process and ensuring the surface quality of the product.

[0010] Further, the adjusting seat includes a base fixed to the bottom of the liquid return groove and adjusting mechanisms arranged on both sides of the base. The two sides of the absorbing plate are connected to the two sides of the base through the two adjusting mechanisms, respectively. The adjusting mechanisms are used to control the distance between the absorbing plate and the bottom of the liquid return groove. When facing different sizes and specifications of the insulating sheath of the umbilical cable electrical unit, the operator can flexibly adjust the height of the absorbing plate according to the actual needs to ensure that it is always in the best splash-proof position.

[0011] Further, the adjusting mechanism includes an outer slide rod, an inner slide rod, and a pin body. The bottom of the inner slide rod is fixed to one side of the upper end face of the base. The outer slide rod is vertically slidably connected to the outer wall of the inner slide rod, and the top thereof is fixedly connected to the absorbing plate. First pin holes are vertically and spaced apart on the side wall of the outer slide rod. Second pin holes are vertically and spaced apart on the side wall of the inner slide rod. The pin body is sequentially inserted into the first pin holes and the second pin holes to limit the vertical position of the outer slide rod. The combination of the outer slide rod, the inner slide rod, and the pin body realizes precise adjustment of the height of the absorbing plate.

[0012] Further, the base has an "H" shape, and a strong magnetic block is installed on the bottom surface of the base to be adsorbed on the bottom of the liquid return groove. This provides better structural support to ensure that the adjusting mechanism remains stable when carrying the absorbing plate and dealing with the impact of the splash, and optimizes the space layout to provide a reasonable installation position for the adjusting mechanisms on both sides. At the same time, the strong magnetic block is installed on the bottom surface of the base, so that the base can be firmly adsorbed on the bottom of the liquid return groove.
