Description

Technical Field

[0001] This application relates to the field of cable production equipment technology, and in particular to a warm water crosslinking reel for cables. Background Technology

[0002] In wire and cable manufacturing, the warm water crosslinking process is mainly used for insulation layer processing to meet the safe operation requirements of wires and cables under long-term energization, ambient temperature fluctuations, and harsh outdoor conditions, and to avoid accidents such as leakage and short circuits caused by insulation layer performance failure.

[0003] The commonly used warm water crosslinking process is as follows: First, molten insulating polymer material is coated onto the conductor core through an insulating extrusion process, forming a preliminary insulating structure. Then, the entire core, wound on a take-up reel, is transferred to a constant-temperature warm water tank. The water temperature is strictly controlled between 86-90℃, and a circulating heating system continuously maintains a stable temperature. The core is then immersed in the warm water for a set time (usually determined by the core specifications and insulation thickness, typically 2-8 hours). In actual production, the take-up reel, as the core transfer and immersion device, is mainly made of metal or high-strength engineering plastics, possessing good load-bearing strength and core winding capacity to meet the requirements of core transfer safety and production efficiency.

[0004] Most existing coils lack permeable holes in their bottom area and along their sides. Even those with a few permeable holes often have insufficient permeability due to their small size and uneven distribution. When the entire coil of wire is immersed in a warm water tank, the water cannot penetrate the coil structure to reach the inside of the wire. It can only contact the wire on the surface of the coil, while the wire in the middle and inner layers of the coil remains in a "semi-closed" state, unable to fully contact the warm water. This results in differences in the degree of cross-linking reaction of the insulation material in different areas of the wire, causing a significant drop in product qualification rate, increasing production costs and production cycle, and even posing a major safety hazard due to insulation failure during subsequent use, leading to short circuits, leakage, and other safety accidents. Utility Model Content

[0005] The purpose of this application is to provide a warm water crosslinking reel for cables to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a hot water crosslinking reel for cables, including a cylindrical body, a shaft cylinder, and two side baffles. The cylindrical body has a plurality of first water passage holes on its side wall. The shaft cylinder is coaxially fixed inside the cylindrical body, and a water passage channel is formed between the outer side wall of the shaft cylinder and the inner side wall of the cylindrical body. The first water passage holes communicate with the water passage channel. The two side baffles are respectively fixed at both ends of the cylindrical body. The diameter of the side baffles is larger than the diameter of the cylindrical body. The side baffles have shaft holes that communicate with the inside of the shaft cylinder. The end face of the side baffles near the cylindrical body has a radially extending water passage groove that communicates with the water passage channel so that water can enter the water passage channel from the water passage groove when the cable core is wound on the cylindrical body.

[0007] Furthermore, the side baffle is provided with multiple water passage grooves, which are evenly spaced along the circumference of the side baffle.

[0008] Furthermore, the side baffle is provided with a raised structure, which protrudes from the end face near the cylinder to the end face away from the cylinder; on the end face near the cylinder, the raised structure forms a recessed part, which forms a water passage groove; on the end face away from the cylinder, the raised structure forms a raised rib.

[0009] Furthermore, the side baffle forms a water passage area between two adjacent water passage grooves, and the water passage area is provided with multiple second water passage holes.

[0010] Furthermore, multiple second water passage holes are evenly spaced along the radial direction of the side baffle in the water passage area.

[0011] Furthermore, the multiple first water passage holes are divided into multiple water passage hole groups, and the multiple water passage hole groups are evenly spaced along the circumference of the cylinder. Each water passage hole group includes multiple first water passage holes that are evenly spaced along the axial direction of the cylinder.

[0012] Furthermore, a hanging hole is provided on the end face of the side baffle relative to the water passage trough. The hanging hole extends radially along the side baffle and is connected to the water passage trough.

[0013] Furthermore, a reinforcing rib is provided at the location of the hanging hole in the water passage, and the reinforcing rib has an opening for the hanging hole to communicate with the water passage.

[0014] Furthermore, the shaft cylinder includes a main cylinder section and a fixing part that is detachably connected to both ends of the main cylinder section along the axial direction. The fixing part is fixed on the side of the cylinder body opposite to the side baffle, and the diameter of the fixing part is larger than the diameter of the shaft hole, so as to fix the shaft cylinder inside the cylinder body.

[0015] Furthermore, the fixing part is provided with a shaft through hole, which communicates with the interior of the main cylinder part. The shaft through hole includes a first hole and a second hole that are connected in sequence. The second hole communicates with the interior of the main cylinder part, and the diameter of the first hole gradually increases from the inside to the outside along the axial direction.

[0016] The beneficial effects of the technical solution provided in this application include at least the following: This application utilizes a water-passing groove and a first water-passing hole. When the wire core is wound on the cylinder, water can flow through the water-passing groove into the water-passing channel, and then penetrate through the first water-passing hole to the inner side of the wound wire core, forming a three-dimensional water-permeable structure in both the radial and transverse directions. This allows warm water to fully penetrate all areas of the wire core, thereby improving the uniformity of the cross-linking reaction of the wire core and increasing the product qualification rate.

[0021] Example Please see Figures 1-2 A warm water crosslinking reel for cables includes a cylindrical body 100, a shaft cylinder 200, and two side baffles 300. The cylindrical body 100 has a plurality of first water passage holes 110 on its side wall. The shaft cylinder 200 is coaxially fixed inside the cylindrical body 100, and a water passage channel 120 is formed between the outer side wall of the shaft cylinder 200 and the inner side wall of the cylindrical body 100. The first water passage holes 110 communicate with the water passage channel 120. The two side baffles 300 are respectively fixed at both ends of the axial direction of the cylindrical body 100. The diameter of the side baffles 300 is larger than the diameter of the cylindrical body 100. The side baffles 300 have shaft holes 310 that communicate with the inside of the shaft cylinder 200. The end face of the side baffles 300 near the cylindrical body 100 has a radially extending water passage groove 320 that communicates with the water passage channel 120 so that water can enter the water passage channel 120 from the water passage groove 320 when the cable core is wound on the cylindrical body 100.

[0022] In this embodiment, as Figure 1 , Figure 2 As shown, the cylinder 100 has a cylindrical structure and is supported by high-strength metal or engineering plastic as the main load-bearing component, so that the cable core can be wound on the side wall of the cylinder 100. The inside of the cylinder 100 is a hollow structure, and multiple first water passage holes 110 are opened on its side wall, so that water can pass through the first water passage holes 110 to penetrate the side wall of the cylinder 100. The shaft cylinder 200 is the central support component of the disc. It can be made of the same material as the cylinder 100. The shaft cylinder 200 has a cylindrical structure, is coaxially arranged with the cylinder 100 and fixed inside the cylinder 100. The shaft cylinder 200 is for the transfer shaft of the production line to pass through. Its inner diameter is adapted to the diameter of the transfer shaft of the production line, and the outer diameter of the shaft cylinder 200 is smaller than the inner diameter of the cylinder 100. This forms a water passage 120 between the outer wall of the shaft cylinder 200 and the inner wall of the cylinder 100. The water passage 120 is connected to the first water passage hole 110 on the side wall of the cylinder 100, thus forming a channel through which water can penetrate laterally.

[0023] The side baffle 300 is a circular disc structure, and its material can be the same as that of the cylinder 100. The diameter of the side baffle 300 is larger than the outer diameter of the cylinder 100. The two side baffles 300 are fixed at both ends of the cylinder 100 in the axial direction, and the side baffles 300 and the cylinder 100 are coaxially arranged so that the side baffles 300 can limit the wire core wound on the cylinder 100. The center of the side baffle 300 is provided with a shaft hole 310. The inner diameter of the shaft hole 310 matches the inner diameter of the shaft cylinder 200 and is completely connected to the inside of the shaft cylinder 200 for fitting the transfer shaft. A water passage groove 320 is opened on the inner end face of the side baffle 300 (i.e. the end face close to the cylinder 100). The water passage groove 320 extends radially along the side baffle 300 and is connected to the water passage channel 120. Its outer end can extend to the edge of the side baffle 300, thereby forming a radial channel for water to enter the interior from the outside of the disc.

[0024] In practice, after the insulation extrusion process is completed, the pre-formed insulated wire core is evenly wound along the outer wall of the cylinder 100. The two side baffles 300 act as limiters to prevent the wire core from falling off from both ends of the cylinder 100 during the winding process. After the wire core is wound, the transfer shaft connects the reel to the production line transfer equipment through the shaft hole 310 in the center of the side baffle 300 and the shaft cylinder 200 located inside the cylinder 100. The transfer equipment slowly immerses the reel with the wire core wound into a constant temperature water tank with a temperature of 86-90℃ until the reel is completely submerged, so that the top of the side baffle 300 is below the water surface. Then, the soaking time is set according to the wire core specifications. The circulating heating system of the warm water tank maintains a stable water temperature, providing conditions for the cross-linking reaction of the insulation material.

[0025] During the soaking process, the warm water first comes into contact with the outer edge of the side baffle 300, flows towards the center along the water groove 320 on the inner end face of the side baffle 300, and enters the water passage 120 between the shaft cylinder 200 and the cylinder 100. The warm water that enters the water passage 120 then passes through multiple first water passage holes 110 on the side wall of the cylinder 100 and evenly penetrates into the inside of the wire core wrapped on the outside of the cylinder 100, ensuring that the water flow continuously and evenly contacts all the wire cores of the inner layer, middle layer and surface layer.

[0026] The aforementioned structure, by providing a water channel 320 on the side baffle 300 and a first water passage hole 110 on the side wall of the cylinder 100, allows water to flow through the water channel 320 into the water passage channel 120 during the winding of the wire core on the cylinder 100. Water then permeates through the first water passage hole 110 to the inner side of the wound wire core, forming a radial and transverse three-dimensional permeable structure. This allows warm water to fully penetrate all areas of the wire core, effectively preventing the phenomenon of a qualified surface layer but an unqualified inner layer, thereby improving the uniformity of the cross-linking reaction of the wire core and further increasing the product qualification rate. Simultaneously, the three-dimensional permeable structure increases the contact area between warm water and the wire core, effectively improving the heat exchange efficiency between the insulation material and warm water, further shortening the soaking time required for the cross-linking reaction, shortening the production cycle, and indirectly reducing the company's time costs.

[0027] In the specific structure of the side baffle 300, the side baffle 300 is provided with multiple water passage grooves 320, which are evenly spaced along the circumference of the side baffle 300.

[0028] In this embodiment, as Figure 1 As shown, the number of water passage troughs 320 can be determined according to the specifications of the side baffle 300. Taking eight water passage troughs 320 as an example, these multiple water passage troughs 320 are radially and evenly distributed along the circumference of the side baffle 300, so that the central angle between two adjacent water passage troughs 320 is 45°, thereby allowing water to flow evenly into the water passage channel 120 from the circumference of the side baffle 300. Furthermore, the water passage troughs 320 can be rectangular or trapezoidal, with the opening slightly wider than the bottom, thus facilitating water flow.

[0029] In the above structure, multiple water channels 320 are evenly spaced along the circumference, allowing warm water to enter simultaneously from multiple points along the circumference of the side baffle 300. This avoids water flow deviation caused by a single or local water channel 320, ensuring that the warm water around the coil can be evenly distributed to the water channel 120, providing equal amounts of warm water contact to all areas of the wire core, especially the wire cores wound at different circumferential positions on the cylinder 100, further improving the uniformity of the crosslinking reaction.

[0030] The side baffle 300 is provided with a protruding structure, which protrudes from the end face near the cylinder 100 to the end face away from the cylinder 100; on the end face near the cylinder 100, the protruding structure forms a recessed part, which forms a water passage groove 320; on the end face away from the cylinder 100, the protruding structure forms a rib 330.

[0031] In this embodiment, as Figure 1As shown, the side baffle 300 has multiple protruding structures. These protruding structures extend from the inner end face of the side baffle 300 to the outer end face, and are arranged radially and evenly at intervals along the circumference of the side baffle 300. The number of these protruding structures is the same as the number of water passage grooves 320. The protruding structures extend radially along the side baffle 300. Specifically, on the inner end face of the side baffle 300, when the protruding structure protrudes towards the outer end face, it forms an outwardly recessed portion on the inner end face, which constitutes the water passage groove 320. Correspondingly, on the outer end face of the side baffle 300, the protruding structure forms an outwardly protruding rib 330. In the production of the side baffle 300, the side baffle 300 and the protruding structures are integrally formed using high-strength metal or reinforced engineering plastic through stamping, injection molding, or milling to ensure the structural integrity of the recessed portion and the rib 330, without any seams, and to avoid cracking due to local stress when immersed in warm water.

[0032] In the above structure, by simultaneously forming the water channel 320 and the rib 330 with the same raised structure, there is no need for additional processing of the water channel or the addition of reinforcing components. This reduces the processing steps of the side baffle 300, lowers manufacturing costs, and avoids problems such as water leakage or weakening of strength that may occur when splicing multiple components. The rib 330 of the side baffle 300, which is opposite to the end face of the cylinder 100, is distributed radially, effectively dispersing the radial tension generated when the wire core is wound, improving the deformation resistance of the side baffle 300, further strengthening the structural strength of the side baffle 300, and enhancing its durability.

[0033] In addition, the side baffle 300 forms a water passage area 340 between two adjacent water passage grooves 320, and the water passage area 340 is provided with a plurality of second water passage holes 341. The plurality of second water passage holes 341 are evenly spaced along the radial direction of the side baffle 300 in the water passage area 340.

[0034] In this embodiment, as Figure 1 As shown, the side baffle 300 is provided with eight water passage grooves 320. The fan-shaped area between two adjacent water passage grooves 320 forms a water passage area 340 with a central angle of 45°. Multiple second water passage holes 341 are provided in the water passage area 340. Each second water passage hole 341 is a through-hole structure extending axially along the side baffle 300. In actual operation, water can penetrate to the wire core through these second water passage holes 341. Specifically, each water passage area 340 has 3-5 second water passage holes 341 evenly spaced radially along the side baffle 300. These multiple second water passage holes 341 are arranged in a straight line to ensure that water can evenly penetrate radially to wire cores with different winding layers.

[0035] In the specific arrangement structure of the first water passage hole 110, the multiple first water passage holes 110 are divided into multiple water passage hole groups. The multiple water passage hole groups are evenly spaced along the circumference of the cylinder 100, and each water passage hole group includes multiple first water passage holes 110 that are evenly spaced along the axial direction of the cylinder 100.

[0036] In this embodiment, as Figure 1 , Figure 2 As shown, multiple sets of water passage hole groups are provided on the side wall of the cylinder 100. Each water passage hole group has multiple first water passage holes 110, and the number of first water passage holes 110 in each group is the same. The multiple sets of water passage hole groups are evenly spaced along the circumference of the cylinder 100 to ensure the symmetrical distribution of the first water passage holes 110 in each group on the circumference of the cylinder 100, thereby avoiding local dense or sparse first water passage holes 110. Furthermore, the multiple first water passage holes 110 in each set of water passage hole groups are evenly spaced along the axial direction of the cylinder 100. The number of first water passage holes 110 in each set is determined by the length of the cylinder 100 to ensure that the entire wire core winding area in the axial direction of the cylinder 100 is covered. For example, 12 sets of water passage hole groups can be provided, and each set of water passage hole groups includes 5 first water passage holes 110.

[0037] The water passage hole groups are evenly spaced along the circumference, and each water passage hole group is aligned along the axial direction. The multiple first water passage holes 110 of each water passage hole group are spaced along the axial direction of the cylinder 100, so that after the water flows in from the water passage channel 120, it can penetrate into the wire core evenly and axially through the first water passage holes 110 of each water passage hole group, further improving the consistency of the cross-linking reaction, shortening the time from when the warm water enters the reel to when it contacts the wire core, and further shortening the cross-linking soaking cycle.

[0038] In addition, a hanging hole 350 is provided on the end face of the side baffle 300 opposite to the water passage 320. The hanging hole 350 extends radially along the side baffle 300 and communicates with the water passage 320. A reinforcing rib plate 400 is provided inside the water passage 320 at the position of the hanging hole 350. The reinforcing rib plate 400 is provided with an opening 410 for communicating between the hanging hole 350 and the water passage 320.

[0039] In this embodiment, as Figure 1 , Figure 2 As shown, the outer end face of the side baffle 300 is provided with a hanging hole 350, which allows the hook to be inserted into the hanging hole 350 during transportation, enabling the quick lifting and movement of the plate. The hanging hole 350 is a long groove-shaped structure, and its width is adapted to the width of commonly used industrial hooks. The hanging hole 350 is connected to the water passage 320, so that during the warm water crosslinking process, water can flow through the hanging hole 350 into the water passage 320, thereby increasing the water supply channel.

[0040] Furthermore, the reinforcing rib 400 is fixed inside the water passage 320 and located in the corresponding area of ​​the hanging hole 350 within the water passage 320. It is fixed to the wall of the water passage 320 by welding or other methods, ensuring that it forms an integral load-bearing structure with the side baffle 300 body. The reinforcing rib 400 is a rectangular sheet structure, and its edge fits seamlessly with the wall of the water passage 320, thereby preventing water leakage or accumulation of impurities at the fitting point. An opening 410 is provided at the center of the reinforcing rib 400 to facilitate the insertion of industrial hooks, which does not obstruct water permeability and enhances the structural strength of the area of ​​the hanging hole 350 through the reinforcing rib 400.

[0041] In the specific structure of the shaft cylinder 200, the shaft cylinder 200 includes a main cylinder portion 210 and a fixing portion 220 detachably connected to both ends of the main cylinder portion 210 along the axial direction. The fixing portion 220 is fixed to the side of the side baffle 300 opposite to the cylinder body 100, and the diameter of the fixing portion 220 is larger than the diameter of the shaft hole 310, so as to fix the shaft cylinder 200 inside the cylinder body 100. The fixing portion 220 is provided with a shaft through hole 221, which communicates with the inside of the main cylinder portion 210. The shaft through hole 221 includes a first hole portion 222 and a second hole portion 223 connected in sequence. The second hole portion 223 communicates with the inside of the main cylinder portion 210, and the diameter of the first hole portion 222 gradually increases from the inside to the outside along the axial direction.

[0042] In this embodiment, as Figure 2 As shown, the main cylinder 210 is a cylindrical hollow structure with an inner diameter that matches the transfer shaft and an outer diameter that is smaller than the inner diameter of the cylinder 100. This forms a water passage 120 between the outer wall of the main cylinder 210 and the inner wall of the cylinder 100. The axial length of the main cylinder 210 is the same as the axial length of the cylinder 100. The end faces of the main cylinder 210 are flush with the end faces of the cylinder 100. Both ends of the main cylinder 210 are provided with detachable connection structures, such as internal threaded holes or snap-fit ​​grooves, for assembly with the fixing part 220. The fixing part 220 can be a stepped disc structure, used to fix the shaft cylinder 200 from the outside of the side baffle 300. The end of the fixing part 220 near the main cylinder part 210 is provided with a connection structure that matches the main cylinder part 210, such as an external threaded post or a snap-fit ​​boss, so that it can be detachably connected to both ends of the main cylinder part 210. After the fixing part 220 is assembled at both ends of the main cylinder part 210, it fits against the outer end face of the side baffle 300, and the inner end face of the fixing part 220 fits tightly against the outer end face of the side baffle 300. The fixing diameter is larger than the diameter of the shaft hole 310 of the side baffle 300, forming an axial limit on the side baffle 300, thereby fixing the entire shaft cylinder 200 inside the cylinder body 100 and preventing the shaft cylinder 200 from axial displacement during transportation or soaking.

[0043] The fixing part 220 has a through hole at its center, forming a shaft passage hole 221. A second hole 223 located on the inner side of the shaft passage hole 221 communicates with the interior of the main cylinder part 210. A first hole 222 on the outer side allows the production line transfer shaft to be inserted. The axis of the shaft passage hole 221 coincides with the axis of the main cylinder part 210, ensuring that the transfer shaft passes coaxially through the shaft cylinder 200. Furthermore, the first hole 222 has a flared shape with a diameter that gradually increases from the inside to the outside along the axial direction. Compared to a traditional straight hole, this improves the centering tolerance when inserting the transfer shaft, eliminating the need for repeated position adjustments and improving overall production efficiency.

[0044] In the embodiments disclosed in this application, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this application according to the specific circumstances.

[0045] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
