Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing equipment technology, and in particular to a cable sheath cooling and shaping device. Background Technology

[0002] During cable production, the sheath is heated and plasticized in the extruder and then tightly wrapped around the cable core. At this time, the sheath temperature is very high, and it is in a molten or semi-molten state. It must be cooled in a timely and uniform manner to set its shape and achieve the required mechanical properties, electrical properties, and appearance quality.

[0003] A search revealed that patent CN214820759U states that "This utility model applies to the field of cable production technology, providing a cable cooling and shaping device. The cooling and shaping device includes: a housing; a cooling component disposed on the housing for cooling and shaping the cable; and a heat dissipation component disposed on the housing for dissipating heat and cooling the cooling water. The cooling component includes: a circulating water cooling component; and an ice-cooling component disposed on the circulating water cooling component for rapidly cooling the water flow to improve the cable cooling and shaping rate and effect. The cable to be cooled and shaped is placed in the circulating water cooling component and the cooling water circulates, while the ice-cooling component further cools the water flowing to the circulating water cooling component." The water flow in the component rapidly cools and lowers the temperature. Under the action of the flowing low-temperature water, the cable to be cooled and formed is rapidly and efficiently cooled and formed. The water returning to the box is cooled and lowered by the heat dissipation components, keeping its temperature at a low level to ensure the cooling effect on the cable during subsequent use. This device cools and lowers the temperature of the cooling water, thereby enabling the cable to form quickly. However, the heat exchange efficiency between the flowing water and the cable is low, requiring a long water tank to meet the cooling requirements. It occupies a lot of space, and the degree of contact between the upper and lower surfaces of the cable and the water is different. Moreover, when the water flow rate is slow, a temperature gradient is easily formed around the cable, causing the sheath to deform or become eccentric due to uneven cooling and contraction.

[0004] To address this issue, we provide a cable sheath cooling and shaping device. Utility Model Content

[0005] The purpose of this invention is to provide a cable sheath cooling and shaping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable sheath cooling and shaping device, comprising a frame and a housing, wherein a water guide pipe is provided on the inner wall of the housing, a diversion pipe is provided on the outer side of the water guide pipe, and a nozzle is provided on the outer side of the diversion pipe; a water storage tank is provided at the bottom of the housing, and a water pump is provided on one side of the water storage tank, the outlet of the water pump being connected to the water guide pipe; a guide wheel for supporting and guiding the cable is also provided inside the housing; and a drain plate is provided at the bottom of the housing to allow the sprayed cooling water to flow back to the water storage tank.

[0007] Preferably, the water storage tank is provided with a first heat dissipation plate on its outer side, and the water storage tank is connected to the outer shell through a guide channel.

[0008] Preferably, the guide channel has an inverted trapezoidal structure.

[0009] Preferably, it further includes a cooling pool disposed on one side of the outer casing, wherein a limiting wheel is provided at one inner end of the cooling pool and a second heat dissipation plate is provided on the outer side of the cooling pool.

[0010] Preferably, the water guide pipe is provided in two sets.

[0011] Preferably, the diversion pipes are evenly distributed on the outside of the water guide pipe, and the nozzles are arranged laterally on the outside of the diversion pipes.

[0012] Preferably, a control panel is provided on the outer side of the housing.

[0013] Preferably, the guide wheels are provided in at least three sets.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a ring-shaped spray system composed of water guide pipes, distribution pipes, and nozzles installed on the inner wall of the outer casing. This system enables simultaneous and uniform spray cooling of the cable sheath from all sides, effectively eliminating the temperature gradient caused by the difference in contact between the upper and lower surfaces in traditional water tank cooling. This avoids the "bamboo joint" deformation or eccentricity problems caused by uneven cooling and shrinkage of the sheath, ensuring the roundness and performance stability of the cable. The cooling pool located on one side of the outer casing provides a secondary cooling zone for the cable, allowing for staged cooling using different cooling media according to the process requirements of different sheath materials. This helps release internal stress and further optimizes the microstructure and long-term performance of the sheath. Positioning wheels ensure the correct positioning of the cable within the cooling pool. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 As shown, the cable sheath cooling and shaping device of this embodiment includes a frame 11 and a housing 12. A water guide pipe 201 is provided on the inner wall of the housing 12, and a diversion pipe 202 is provided on the outer side of the water guide pipe 201. A nozzle 203 is provided on the outer side of the diversion pipe 202. A water storage tank 205 is provided at the bottom of the housing 12, and a water pump 204 is provided on one side of the water storage tank 205. The outlet of the water pump 204 is connected to the water guide pipe 201. A guide wheel 209 for supporting and guiding the cable is also provided inside the housing 12. The bottom of the housing 12 is provided to allow the sprayed cooling water to flow back to the water storage tank 201. The 208 of the 5-inch filter plate and the frame 11 are welded with high-strength steel pipes, which have stable load-bearing capacity. The outer shell 12 is used to fix and install other components. The water guide pipe 201 is made of copper or stainless steel pipe, which has good corrosion resistance. Multiple diversion pipes 202 are welded to the outside of the water guide pipe 201 to make the spraying uniform. Water is evenly sprayed on the outside of the cable through the nozzle 203. The water storage tank 205 is a directional box used to store the coolant required for spraying. The coolant is pumped into the water guide pipe 201 through the water pump 204. The coolant after spraying is collected through the filter plate 208.

[0019] Furthermore, a first heat dissipation plate 206 is provided on the outside of the water storage tank 205. The water storage tank 205 is connected to the outer shell 12 through the guide channel 207. The first heat dissipation plate 206 cools the coolant, and the guide channel 207 collects the sprayed coolant.

[0020] Furthermore, the guide channel 207 has an inverted trapezoidal structure, which allows for better collection of coolant.

[0021] Furthermore, it also includes a cooling pool 210 disposed on one side of the outer casing 12. A limiting wheel 211 is provided at one end of the inner side of the cooling pool 210, and a second heat dissipation plate 212 is provided on the outer side of the cooling pool 210. The cooling pool 210 can perform secondary cooling on the cable to ensure complete cooling. The limiting wheel 211 can prevent the cable from deviating. The second heat dissipation plate 212 can maintain the internal temperature of the cooling pool 210.

[0022] Furthermore, the water guide pipe 201 is provided in two sets, thereby ensuring the uniformity of spray cooling through the two sets of water guide pipes 201.

[0023] Furthermore, the diversion pipes 202 are evenly distributed on the outside of the water guide pipes 201, and the nozzles 203 are horizontally distributed on the outside of the diversion pipes 202. This arrangement ensures the uniformity of spray cooling.

[0024] Furthermore, a control panel 3 is provided on the outside of the housing 12. Through the control panel 3, the water pump 204 can be started or stopped, and the power of the water pump 204 can be adjusted to meet the cooling needs of cable sheaths of different diameters and materials.

[0025] Furthermore, the guide wheel 209 is provided with at least three sets, which ensures that the cable remains stable during the cooling process.

[0026] Working Principle: During operation, the cable enters from one end of the outer casing 12 and passes through at a constant speed under the support and guidance of the guide wheel 209. Simultaneously, the water pump 204 pumps cooling water from the storage tank 205 into the water guide pipe 201. After being distributed by the diversion pipe 202, the water is sprayed onto the cable sheath surface by numerous nozzles 203, forming a uniform water curtain. The heat is quickly carried away, and the water flows through the strainer 208, collects through the guide channel 207, and finally flows back into the storage tank 205. The water, still carrying residual heat, undergoes initial cooling in the storage tank 205 through the first heat dissipation plate 206, completing one cycle. This completes the operation of the cable sheath cooling and shaping device.

[0027] Based on Embodiment 1, to meet higher-level process requirements, this embodiment adds a cooling tank 210 to the cable outlet side of the outer casing 12. The cooling tank 210 is a rectangular water tank with a second heat dissipation plate 212 on its outer side. A limiting wheel 211 is installed inside the inlet end of the cooling tank 210 to accurately position the initially cooled cable and prevent it from swinging in the cooling tank 210. Similarly, a second heat dissipation plate 212 is installed on the outer wall of the cooling tank 210 to dissipate heat from the water in the cooling tank.

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