Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and particularly to a production process and equipment for cross-linked polyethylene insulated cables. Background Art

[0002] Cross-linked polyethylene insulated cables are widely used for power transmission and distribution. They are characterized by using specially treated polyethylene as the insulating material. By chemical or physical methods, cross-linked structures are formed between polyethylene molecules, thereby greatly improving the thermal stability, mechanical strength, and environmental stress cracking resistance of the material.

[0003] In the production process of cross-linked polyethylene insulated cables, the cooling step is an essential part. After the cable is extruded and formed at high temperature, it is necessary to reduce the temperature through water cooling or other cooling methods to ensure the physical properties of the material and the smooth progress of subsequent processing steps. However, this process will cause water droplets to remain on the surface of the cable, which is a potential factor affecting the quality of the cable, because the residual moisture may cause a decrease in electrical performance or affect subsequent processing steps.

[0004] Currently, one of the common methods to remove the residual water droplets on the cable surface is to use the sponge absorption technology. This method wipes the surface of the cable by passing it through a device containing water-absorbing materials (such as sponges) to achieve the purpose of removing moisture. However, this method has certain limitations. As the sponge continuously absorbs water and gradually becomes saturated inside, if the accumulated water in the sponge is not discharged in time, not only can it no longer effectively remove the water droplets on the cable surface, but it may also cause the cable surface to be re-attached with water droplets, reducing the treatment effect of the residual moisture, and thus affecting the overall quality of the cable. Summary of the Invention

In addition, in the description of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0035] First Embodiment

[0036] Please refer to Figures 1 to 6 , the present invention provides a cross-linked polyethylene insulated cable production device, including a base 101, a feeding roller 102, a winder 103, a cooling tank 104, a water scraping ring 105, two sliding blocks 106, two sponge pads 107, two water squeezing plates 108 and a driver 109. The winder 103 is arranged on one side of the base 101, the feeding roller 102 is arranged inside the base 101, the cooling tank 104 is arranged at the bottom of the base 101, the water scraping ring 105 is arranged on one side of the feeding roller 102, the cable passes through the water scraping ring 105, the two sliding blocks 106 are arranged on both sides of the cable, the two sponge pads 107 are respectively arranged on the two sliding blocks 106, and the driver 109 is used to drive the two sliding blocks 106 to move.

[0037] In this embodiment, the winder 103 is arranged on one side of the base 101, and its function is to automatically wind the processed cable to ensure that the cable can be neatly stored after all processing steps, which is convenient for subsequent transportation and use. The feeding roller 102 is located inside the base 101 and is responsible for providing the initial placement point of the cable to be processed and supporting the smooth entry of the cable into the cooling tank 104. The cooling tank 104 is arranged at the bottom of the base 101 and is mainly used to quickly cool the cable just extruded and formed at high temperature to stabilize the physical properties of the material and ensure the quality of subsequent processing.

[0038] A water scraping ring 105 is provided on one side of the feeding roller 102, and the cable needs to pass through this water scraping ring 105. The purpose of the water scraping ring 105 is to initially remove the water droplets formed on the cable surface due to cooling and reduce the moisture residue. To further improve the drying effect, the device is also equipped with two sliding blocks 106. These two sliding blocks 106 are respectively located on both sides of the cable and can be flexibly adjusted in position to adapt to cables of different specifications. A sponge pad 107 is provided on each sliding block 106, and these sponge pads 107 are in direct contact with the cable surface to effectively absorb the remaining moisture. At the same time, the presence of two water squeezing plates 108 is to periodically squeeze the sponge pads 107 to drain the accumulated moisture and maintain the water absorption capacity of the sponge.

[0039] Finally, the entire system is controlled by a driver 109. The function of this driver 109 is to drive the two sliding blocks 106 to move, so that the sponge pads 107 are close to the water squeezing plates 108 to squeeze out the excess moisture, and then reset to continue absorbing the water on the cable. This design not only improves the automation level of cable production, but also greatly enhances the processing efficiency and product quality, and solves the problem that it is difficult to completely remove the residual moisture in the traditional method.

[0040] The water scraping ring 105 includes a ring body 110, a hydrophobic layer 111, a liquid outlet 112 and a support member 113. The support member 113 is slidably arranged on one side of the base 101. The ring body 110 is arranged on the support member 113. The hydrophobic layer 111 is arranged on the ring body 110. The liquid outlet 112 is fixed at the bottom of the ring body 110.

[0041] The ring body 110, as the main structural component of the water scraping ring 105, bears all other components. It is installed on the support member 113 to ensure that the entire water scraping ring 105 can stably contact the cable, and at the same time allows necessary adjustments to adapt to cables of different diameters. To improve the water removal efficiency, a hydrophobic layer 111 is provided on the ring body 110. This layer of material has good hydrophobic properties, can effectively reduce the water adhesion, and helps to guide the water to the designated position to avoid secondary pollution of the cable surface. The liquid outlet 112 is fixed at the bottom of the ring body 110 and is used to discharge the collected moisture or cleaning liquid. By reasonably arranging the position of the liquid outlet 112, it can be ensured that the moisture removed from the cable surface can quickly leave the working area and prevent the moisture from reattaching to the cable, thus ensuring the cable drying effect.

[0042] The support member 113 includes a first magnetic plate 114, a second magnetic plate 115, a support rod 116, and a rotating head 117. The first magnetic plate 114 is slidably disposed on the base 101. The second magnetic plate 115 is connected corresponding to the first magnetic plate 114. The support rod 116 is fixedly connected to the first magnetic plate 114. The rotating head 117 is rotatably disposed on the support rod 116. The annular body 110 is fixed to the rotating head 117.

[0043] The support member 113 is composed of a first magnetic plate 114, a second magnetic plate 115, a support rod 116, and a rotating head 117. The first magnetic plate 114 is slidably disposed on the base 101, enabling the entire wiper ring 105 to be finely adjusted in the horizontal direction for precise alignment with the cable path. The second magnetic plate 115 is connected corresponding to the first magnetic plate 114, enhancing the structural stability and adjustment accuracy. One end of the support rod 116 is fixed to the first magnetic plate 114, and the other end is connected to the rotating head 117, which not only provides support in the vertical direction but also enables flexible adjustment of the angle of the wiper ring 105 through the rotating head 117. The annular body 110 is directly fixed to the rotating head 117, ensuring that it can rotate or tilt as needed to maintain the best contact state with the cable.

[0044] The water squeezing plate 108 includes two wedge-shaped blocks 118, an adjusting screw 119, an adjusting motor 120, and a support platform 121. The support platform 121 is slidably disposed on one side of the base 101. The two wedge-shaped blocks 118 are slidably disposed on the support platform 121. The adjusting screw 119 has two sections of opposite threads. The adjusting screw 119 is threadedly connected to the two wedge-shaped blocks 118. The output end of the adjusting motor 120 is connected to the adjusting screw 119.

[0045] The support platform 121 is slidably disposed on one side of the base 101, which not only provides a stable installation foundation for the water squeezing plate 108 but also gives it a certain degree of position adjustment flexibility, enabling it to be finely adjusted according to actual production requirements. The two wedge-shaped blocks 118 are slidably disposed on the support platform 121, such a design allows the wedge-shaped blocks 118 to move flexibly on the support platform 121 to adapt to the extrusion requirements of the sponge pad 107 in different thicknesses or states.

[0046] The design of the adjusting screw 119 is ingenious. It has two sections of opposite threads and is threadedly connected to the two wedge blocks 118. The advantage of this design is that when the adjusting screw 119 rotates, it can drive the two wedge blocks 118 to move towards or away from each other simultaneously, thereby precisely controlling the pressure magnitude and range on the sponge pad 107. The adjusting motor 120 serves as the power source, and its output end is directly connected to the adjusting screw 119. By the forward and reverse rotation of the motor, the rotation of the adjusting screw 119 is achieved, and further the purpose of automatically adjusting the distance between the wedge blocks 118 is realized, greatly improving the operation efficiency and accuracy.

[0047] The wedge block 118 has a plurality of overflow holes 122, and the plurality of overflow holes 122 are distributed on the wedge block 118.

[0048] Each wedge block 118 is provided with a plurality of overflow holes 122, and these overflow holes 122 are evenly distributed on the surface of the wedge block 118. The existence of the overflow holes 122 is to enable the water extruded from the sponge pad 107 to be quickly discharged, avoiding water retention around the wedge block 118 causing secondary pollution or affecting the extrusion effect. In addition, the design of the overflow holes 122 can also help reduce the friction between the wedge block 118 and the sponge pad 107, extend the service life of the sponge pad 107, and ensure that each extrusion can efficiently remove the saturated water in the sponge.

[0049] The driver 109 includes a driving cylinder 123, a connecting block 124, two connecting rods 125, and an elastic member 126. The driving cylinder 123 is fixed on the base 101, the connecting block 124 is connected to the output end of the driving cylinder 123, one ends of the two connecting rods 125 are respectively rotatably connected to the two support platforms 121, the other ends of the two connecting rods are rotatably connected to the connecting block 124, and the elastic member 126 is arranged between the driving cylinder 123 and the connecting block 124.

[0050] The driving cylinder 123 provides the power source for the entire driving system. The output end of the driving cylinder 123 is connected to the connecting block 124. When the driving cylinder 123 expands and contracts, it can drive the subsequent components to perform corresponding actions through the connecting block 124. The connecting block 124, as the core transmission component, not only connects the output end of the driving cylinder 123 but also is rotatably connected to the two support platforms 121 through the two connecting rods 125 respectively. One ends of these two connecting rods 125 are respectively connected to the support structures of the wedge blocks 118 on the two support platforms 121, and the other ends are rotatably connected to the connecting block 124. Such a design enables the action of the driving cylinder 123 to be effectively transmitted to the support platform 121, thereby simultaneously driving the two sliding blocks 106 to approach or move away from the water squeezing plate 108. The elastic member 126 is used to reset the connecting block 124, so as to facilitate the support platform 121 to return to the position close to the cable.

[0051] The driver 109 further includes an auxiliary rod 127 and an auxiliary absorbent cotton 128. The auxiliary rod 127 is fixedly connected to the connection block 124 and is located on one side of the connection block 124. The auxiliary absorbent cotton 128 is arranged on the auxiliary rod 127.

[0052] The auxiliary rod 127 is directly fixed on one side of the connection block 124. The auxiliary absorbent cotton 128 is arranged on the auxiliary rod 127, which provides additional water absorption protection for the cable. When the connection block 124 approaches the cable to push the support platform 121 away from the cable, the auxiliary rod 127 approaches the cable, and absorbs the moisture on the cable through the auxiliary absorbent cotton 128, so that the winder 103 can operate continuously to continuously drive the cable to be dried, improving work efficiency.

[0053] The cross-linked polyethylene insulated cable production equipment further includes a dryer, which is arranged on one side of the auxiliary rod 127.

[0054] The dryer includes a diversion pipe 130, an air outlet ring 131, a heating unit 132 and a side flow pipe 133. The diversion pipe 130 is sleeved on the cable. The air outlet ring 131 is fixed on one side of the diversion pipe 130. The heating unit 132 is arranged on one side of the air outlet ring 131. The side flow pipe 133 is communicated with the diversion pipe 130, and the air outlet holes of the side flow pipe 133 are arranged corresponding to the auxiliary absorbent cotton 128.

[0055] The diversion pipe 130 is designed to be sleeved on the cable. This design enables hot air to directly act on the cable surface, achieving an efficient and uniform heating effect. The diversion pipe 130 not only plays a guiding role, but also can concentrate heat, avoid energy loss, and improve thermal efficiency.

[0056] The air outlet ring 131 is fixed on one side of the diversion pipe 130. By blowing hot air evenly onto the cable surface, the air outlet ring 131 can effectively evaporate any remaining moisture. In order to ensure that the temperature of the hot air is appropriate and has sufficient intensity, the heating unit 132 is arranged on one side of the air outlet ring 131. The heating unit 132 is responsible for generating and maintaining the required high temperature to ensure that the hot air can quickly and thoroughly dry the cable surface.

[0057] The side flow pipe 133 is communicated with the diversion pipe 130, and the air outlet holes are specially designed corresponding to the position of the auxiliary absorbent cotton 128. The purpose of this design is to use hot air to further enhance the drying effect of the auxiliary absorbent cotton 128. Through the hot air discharged from the side flow pipe 133, it can not only help evaporate the moisture absorbed by the auxiliary absorbent cotton 128, but also prevent the problem of secondary pollution caused by increased humidity.

[0058] Second Embodiment

[0059] Please refer to Figure 7 , the present invention also provides a production process for cross-linked polyethylene insulated cables, including:

[0060] S201 Start the take-up reel 103 to drive the cross-linked polyethylene insulated cable to be cooled through the cooling tank 104 for cooling;

[0061] Start the take-up reel 103, which is arranged on one side of the base 101 and is responsible for smoothly pulling and passing the cable formed by high-temperature extrusion through the cooling tank 104. The cooling tank 104 is located at the bottom of the base 101, and its function is to quickly reduce the temperature of the cable, stabilize the physical properties of the material, and provide guarantee for subsequent processing.

[0062] S202 Remove the moisture on the cable surface through the water scraping ring 105;

[0063] When the cable passes through the cooling tank 104, it will pass through a specially designed water scraping ring 105. This water scraping ring 105 can not only initially remove the water droplets formed on the cable surface due to cooling, but also be equipped with a hydrophobic layer 111 and a liquid outlet 112 to improve the water removal efficiency and prevent the moisture from adhering to the cable surface again.

[0064] S203 The cable absorbs the residual moisture on the cable surface through two sponge pads 107;

[0065] The cable will pass through the position where sponge pads 107 are respectively arranged on both sides. These two sponge pads 107 are installed on the sliding block 106 and can be flexibly adjusted according to the specific specifications of the cable, closely fitting the cable surface to effectively absorb any residual moisture.

[0066] S204 After the sponge pads 107 are used for a preset time, start the driver 109 to drive the two sliding blocks 106 to slide, so that the sponge pads 107 approach the water squeezing plate 108 to squeeze water, and at the same time the take-up reel 103 stops moving;

[0067] When the sponge pads 107 work continuously for a period of time, in order to prevent the effect from being affected by water absorption saturation, the system will automatically start the driver 109. The driver 109 drives the sponge pads 107 on the sliding block 106 to move towards the water squeezing plate 108 through controlling components such as the connecting block 124 and the connecting rod for squeezing and draining water. During this process, the take-up reel 103 temporarily stops moving to ensure that the sponge pads 107 can fully drain the accumulated water inside.

[0068] S205 After the water squeezing is completed, the water squeezing plate 108 resets, and the take-up reel 103 continues to move.

[0069] Once the sponge pad 107 completes the water squeezing process, the water squeezing plate 108 will automatically reset, releasing the pressure on the sponge pad 107. Subsequently, the coiler 103 resumes operation, continues to pull the cable forward, and enters the next cycle or undergoes further processing (such as drying). This step ensures the continuity and stability of the entire production process, improving the overall production efficiency and product quality.

[0070] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand the implementation of all or part of the above processes, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
