Description

Technical Field

[0001] The invention belongs to the technical field of cable production, and in particular relates to a cable production molding device. Background Art

[0002] Cables are usually made of several or several groups of wires (at least two wires in each group) twisted together like ropes. Each group of wires is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. Cables have the characteristics of being powered inside and insulated outside.

[0003] Uneven temperature in the cable production tank will have a significant impact on the quality of the cable's plastic insulation and sheath extrusion. During the cable production process, temperature control is crucial to ensure the quality of the cable. If the temperature in the tank is uneven, it will cause the following major problems:

[0004] Impact on the melting and fluidity of plastics: Uneven temperature may cause differences in the melting and fluidity of plastics, which in turn affects the uniformity and consistency of the cable. If the temperature in certain areas is too low, the viscosity of the plastic will increase, making it difficult for the plastic to flow evenly, which may cause the cable surface to appear rough and not smooth. On the contrary, if the temperature in certain areas is too high, the viscosity of the plastic may decrease and the fluidity may increase. Although it is beneficial to improve the surface quality, too high a temperature may also cause the degradation of the plastic, thus affecting the physical and mechanical properties of the cable.

[0005] Impact on the mechanical and physical properties of the cable: Uneven temperature may also cause the mechanical and physical properties of the cable to deteriorate. For example, if the temperature is too low, the plastic may not be fully plasticized, thus affecting the cable's resistance to environmental stress cracking. On the contrary, if the temperature is too high, the plastic may decompose, thus affecting the physical properties and appearance quality of the cable.

[0006] Increased production difficulty and unstable quality: Uneven temperature increases the complexity and difficulty of production, as the temperature needs to be constantly adjusted to suit the needs of different areas. This not only affects production efficiency, but may also lead to unstable quality of the final product. Especially when using materials such as polyethylene, if the temperature is not properly controlled, it may lead to increased crystallinity, which in turn affects the insulation of the cable or the cracking of the sheath in the later stage. Summary of the invention

[0007] The purpose of the present invention is to provide a cable production and molding equipment to solve the problem in the prior art that uneven temperature in the cable production water tank will have a serious impact on the quality of the cable, including the decline of surface quality, mechanical and physical properties and electrical properties.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 3As shown, the present invention provides a cable production and forming equipment, including an upper water trough 1 and a lower water trough 2, the upper water trough 1 is located above the lower water trough 2, an upper water trough bracket 11 is installed at the bottom of the upper water trough 1, the upper water trough bracket 11 is fixed on the lower water trough 2, the upper water trough 1 and the lower water trough 2 are separated by the upper water trough bracket 11, after the cooling water enters the upper water trough 1, it flows into the lower water trough 2, so that the cooling water can be quickly cooled down.

[0030] Furthermore, a first water cooling trough 3 is arranged on one side of the upper water trough 1, and a second water cooling trough 4 is arranged between the first water cooling trough 3 and the upper water trough 1. The cooling water in the first water cooling trough 3 and the second water cooling trough 4 directly flows into the lower water trough 2, thereby preventing the cooling water with higher temperature from flowing into the lower water trough 2.

[0031] Furthermore, a support frame is installed on one side wall of the lower water trough 2, and a main cooling pipe 5 is installed on the support frame. A plurality of shunt pipes 6 are installed on the main cooling pipe 5. The ends of some shunt pipes 6 are located on the inner side of the second water cooling trough 4, and the cooling water enters the second water cooling trough 4 through the shunt pipe 6 to cool the extruded cable. The water temperature in the second water cooling trough 4 is relatively high and is directly discharged into the lower water trough 2. The ends of some shunt pipes 6 are located on the inner side of the upper water trough 1, and the cooling water enters the upper water trough 1 through the shunt pipe 6. The temperature of this part of water is relatively low, and a water flow is formed in the upper water trough 1 to cool the cable, thereby avoiding the uneven cooling temperature during cable production that may affect the plastic insulation and sheath extrusion quality of the cable.

[0032] Furthermore, end covers 41 are provided at the tops of the first water-cooling trough 3 and the second water-cooling trough 4. The relative temperature of the cables in the first water-cooling trough 3 and the second water-cooling trough 4 is relatively high, thereby avoiding the generation of more water vapor to evaporate into the working environment.

[0033] See also Figure 3 As shown, an annular water pipe 31 is provided in the first water cooling tank 3, and a plurality of first cooling pipes 32 are connected to the side wall of the annular water pipe 31. The first cooling pipes 32 are arranged in a ring shape. The extruded cable passes through the annular water pipe 31. The cooling water cools the cable from the annular water pipe 31 and the plurality of first cooling pipes 32, thereby improving the cooling efficiency.

[0034] Furthermore, a support roller 33 is provided in the first water-cooling tank 3. The support roller 33 is connected to the support roller bracket. When the cable moves, it is located at the upper end of the support roller 33, and the support roller 33 supports the cable.

[0035] Furthermore, a limiting ring 34 is provided on one side of the supporting roller 33, and the cable is limited by the limiting ring 34 to prevent the cable from making a large horizontal displacement when passing through the upper water tank 1, so that the cable movement is more stable, thereby making the cable cooling more uniform.

[0036] Reference Figure 4As shown, in this embodiment, a pressing mechanism 7 is provided in the upper water tank 1, and the pressing mechanism 7 is used to extrude the cable into plasticity, thereby preventing the cable surface from being rough and uneven.

[0037] Furthermore, the pressing mechanism 7 is installed on a bracket 8, and the bracket 8 is installed in the upper water tank 1. The bracket 8 supports the pressing mechanism 7. A spoiler mechanism 9 is provided on the pressing mechanism 7. When the cable passes through the pressing mechanism 7, the spoiler mechanism 9 is provided with power. The cooling water in the upper water tank 1 is stirred by the spoiler mechanism 9, so that the water temperature in the upper water tank 1 is more uniform, avoiding the temperature in some areas of the cable being too high, resulting in a decrease in the viscosity of the plastic, and further affecting the uniformity and consistency of the cable.

[0038] Furthermore, a plurality of fixing holes 81 are arranged on the bracket 8, and a pressing mechanism 7 is installed through the fixing holes 81. A plurality of pressing mechanisms 7 are provided, and each pressing mechanism 7 is located between two adjacent diversion pipes 6. A spoiler mechanism 9 is provided between two adjacent diversion pipes 6. The cooling water flowing out of the diversion pipe 6 is stirred by the spoiler mechanism 9, so that the water temperature in the lower water tank 2 is more uniform.

[0039] like Figure 5-Figure 6 As shown, the pressing mechanism 7 includes a pressing bracket 71, and a strip hole 711 is set at the bottom of the pressing bracket 71. The strip hole 711 is used to pass through the bracket 8. The pressing bracket 71 moves on the bracket 8 through the strip hole 711, which facilitates the adjustment of the position of the pressing bracket 71 on the bracket 8.

[0040] The adjusting holes 712 are perpendicular to the strip holes 711. A lower pressing roller bracket 74 is installed with a bolt through the adjusting holes 712 on one side. A lower pressing roller shaft 73 is installed on the lower pressing roller bracket 74 through a bearing seat. The lower pressing roller shaft 73 is installed with a lower pressing roller 72. An annular groove structure is provided in the middle of the lower pressing roller 72. A U-shaped hole is provided on the lower pressing roller bracket 74 for convenient adjustment of the horizontal position of the lower pressing roller bracket 74, and then the horizontal position of the lower pressing roller 72 is adjusted. The height of the lower pressing roller bracket 74 in the vertical direction is adjusted through the adjusting holes 712, and then the height of the lower pressing roller 72 in the vertical direction is adjusted. By adjusting the horizontal and vertical positions of the lower pressing roller 72, the lower pressing roller 72 supports the cable. By replacing the lower pressing roller 72 with a groove structure of different sizes, it can be adjusted according to the diameter of the cable so that the outer surface of the cable fits more closely to the inner wall of the groove structure.

[0041] Furthermore, an upper pressure roller bracket 77 is installed with a bolt through the adjustment hole 712 on the other side, and an upper pressure roller shaft 76 is installed on the upper pressure roller bracket 77 through a bearing seat, and an upper pressure roller 75 is installed on the upper pressure roller shaft 76. A U-shaped hole is provided on the upper pressure roller bracket 77 to facilitate adjustment of the position of the upper pressure roller bracket 77 in the horizontal direction, thereby adjusting the position of the upper pressure roller 75 in the horizontal direction, and adjusting the height of the upper pressure roller bracket 77 in the vertical direction through the adjustment hole 712, thereby adjusting the height of the upper pressure roller 75 in the vertical direction. An annular groove structure is provided in the middle of the roller 75. The structural design of the upper pressure roller 75 is the same as that of the lower pressure roller 72. By adjusting the distance between the upper pressure roller 75 and the lower pressure roller 72, the upper pressure roller 75 squeezes the upper end of the cable and the lower pressure roller 72 squeezes the lower end of the cable, thereby plasticizing the cable. When the cable passes between the upper pressure roller 75 and the lower pressure roller 72, the upper pressure roller 75 is driven to rotate, the upper pressure roller shaft 76 is driven to rotate, and the spoiler mechanism 9 is driven to rotate, so that the cooling water is stirred by the spoiler mechanism 9.

[0042] Furthermore, a fixing foot 78 is provided on one side of the press bracket 71, and the fixing foot 78 is L-shaped. Through holes are provided at both ends of the fixing foot 78. One end of the fixing foot 78 is connected to the press bracket 71 by bolts, and the other end of the fixing foot 78 is connected to the fixing hole 81 of the bracket 8 by bolts, so that the press bracket 71 is fixed to the bracket 8, which facilitates the adjustment of the position of the press bracket 71 on the bracket 8. The position of the press bracket 71 can be adjusted according to the position of the shunt pipe 6, so that the press bracket 71 is located between the two shunt pipes 6.

[0043] Furthermore, the spoiler mechanism 9 includes a fixing frame 91 and a spoiler cover 92. The fixing frame 91 is installed at both ends of the upper pressure roller shaft 76. The length of the upper pressure roller shaft 76 is greater than the width of the pressing bracket 71, so that the fixing frame 91 is located on the outside of the pressing bracket 71. The spoiler cover 92 is configured to be hemispherical, and a groove is provided in the hemispherical shape. The cooling water is continuously stirred by the spoiler cover 92, and the hemispherical spoiler cover 92 scoops out part of the cooling water and then flows into the upper water tank 1, thereby improving the cooling efficiency of the cooling water in the upper water tank 1, making the cable cooled more evenly, thereby improving the mechanical and material properties of the cable.

[0044] The working principle of the present invention is as follows: the cable extruded from the outer sheath first enters the first water-cooling trough 3, the cable is cooled by the first cooling pipe 32, and after being limited by the support roller 33 and the limit ring 34, it enters the second water-cooling trough 4 for cooling, further reducing the temperature of the cable, and the cooling water in the first water-cooling trough 3 and the second water-cooling trough 4 is discharged into the lower water trough 2 for recovery, and the cable then enters the upper water trough 1, and the cable is extruded and plasticized by the cooperation of the upper pressure roller 75 and the lower pressure roller 72, so that the surface of the cable is more uniform and smooth, and the phenomenon of bulging is avoided, thereby improving the mechanical and material properties of the cable. At the same time, due to the friction between the cable and the upper pressure roller 75, the upper pressure roller shaft 76 is driven to rotate, and the spoiler mechanism 9 is driven to rotate, and the fixing frame 91 and the spoiler cover 92 are rotated, and part of the cooling water is fished out and then flows into the upper water trough 1, thereby improving the cooling efficiency of the cooling water in the upper water trough 1, making the cable cooling more uniform, thereby improving the mechanical and material properties of the cable, and the spoiler mechanism 9 does not need to provide additional power, while making the cooling water temperature more uniform, reducing the processing cost.
