Technical Field

[0001] This utility model relates to the field of cable production technology, specifically an annealing device for cable production. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. They have many uses, mainly for control installation, equipment connection, and power transmission, and are a common and indispensable item in daily life. Annealing is an important step in the cable manufacturing process. The current annealing method for cables mostly involves winding the cables into a bundle and then placing them in an annealing furnace for heating. This method makes the cables prone to sticking together due to heat during annealing, which is not convenient for subsequent processing. Furthermore, the annealing furnace does not isolate air and lacks a nitrogen filling mechanism, making the cables prone to oxidation after contact with air, affecting conductivity, flexibility, and subsequent quality.

[0003] Based on this, an annealing device for cable production is now provided, which can eliminate the drawbacks of existing technical solutions. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] In this embodiment, as Figures 1-6As shown, an annealing device for cable production includes a housing 102 for annealing cables 101. The housing 102 has drive devices (not shown) on both sides for conveying the cables 101. One end of the cable 101 extends into the housing 102 via a cleaning mechanism 200 to perform the annealing operation. A support plate 103 is fixedly installed on one side of the housing 102, and a partition 104 is fixedly installed inside the housing 102, dividing the housing 102 into a preheating chamber 10. 5. Annealing chamber 106 and nitrogen generating chamber 107: The upper end of the support plate 103 is fixedly equipped with a cleaning mechanism 200 for wiping the surface of the cable 101 to improve annealing efficiency. The annealing chamber 106 is equipped with an annealing mechanism 300 for uniformly heating the cable 101. The annealing temperature can be controlled at 300~500℃ according to the actual situation. The nitrogen generating chamber 107 is equipped with a nitrogen filling mechanism 400. The nitrogen flow rate can be controlled at 5~10L / min to supply nitrogen to the preheating chamber 105 and the annealing chamber 106 to prevent the cable 101 from oxidizing.

[0027] The cleaning mechanism 200 includes symmetrically arranged vertical plates 201. A fixed plate 202 and a sliding plate 203 are arranged between the two vertical plates 201. The fixed plate 202 is fixedly connected to the vertical plates 201. The sliding plate 203 is located above the fixed plate 202. A groove 204 is opened on the opposite side of the two vertical plates 201. A slider 205 is slidably arranged inside the groove 204. The slider 205 is connected to the vertical plates 201 by several bolts, which facilitates the adjustment of the position of the slider 205 and the sliding plate 203 and facilitates the replacement or disassembly of the cleaning brush 206. The sliding plate 203 is fixedly connected to the slider 205. A cleaning brush 206 is installed on the opposite side of the fixed plate 202 and the sliding plate 203 to facilitate wiping the impurities on the surface of the cable 101 and avoid reaction or adhesion to the surface of the cable 101 at high temperatures, which would affect production efficiency.

[0028] Among them, such as Figure 2 - Figure 6As shown, the annealing mechanism 300 includes several annealing cylinders 301 rotatably disposed inside the annealing chamber 106. A spiral heating wire 302 is arranged axially inside each annealing cylinder 301. The heating wire 302 is fixed inside the annealing cylinder 301 to avoid component interference. The heating wire 302 is electrically connected to the controller 109. Temperature monitoring gauges are installed inside both the annealing cylinder 301 and the preheating chamber 105 for real-time temperature monitoring. Hollow buffer cylinders 303 are symmetrically arranged at both ends of the annealing cylinder 301. The buffer cylinders 303 are fixedly disposed inside the housing 102. Transmission gears 304 are fixedly installed on the outer wall of each annealing cylinder 301. Adjacent transmission gears 304 mesh with each other. All gears are made of high-temperature resistant alloy steel to avoid the effects of high temperatures. One of the transmission gears 304 has a drive gear 305 meshing on one side. The drive gear 305 is fixedly connected to the output end of the drive motor 306, which is fixed inside the housing 102. Compared with the traditional static annealing cylinder arrangement, this annealing cylinder 301 can achieve uniform heating. Several bearing rings 307 are rotatably arranged on the outer side of the annealing cylinder 301 to provide support. The bearing rings 307 are connected to the inner wall of the housing 102 through connecting rods, allowing the cable 101 to pass through the spiral middle for annealing. It can also ensure the uniformity of heat in the annealing cylinder 301 during rotation, and transfer its heat to the preheating chamber 105 to preheat the cable 101, thereby making reasonable use of its heat and saving resources.

[0029] Among them, such as Figure 4 and Figure 5 As shown, the nitrogen charging mechanism 400 includes a nitrogen generator 401 and a pump 402. The nitrogen generator 401 has an existing structure. The nitrogen gas in the nitrogen generator 401 is divided into two paths by a three-way pipe through the pump 402. One path is discharged through a branch pipe 404 in the preheating chamber 105, and the other path enters the annealing cylinder 301 through a vent in the annealing chamber 106, ensuring the normal operation of the mechanism. A three-way pipe is fixedly installed at the output end of the pump 402, and two gas pipes 403 are connected to the three-way pipe. One end of one of the gas pipes 403 extends into the preheating chamber 105 and is connected to several branch pipes 404. One end of the other gas pipe 403 extends into the annealing chamber 106 and is connected to the bearing ring 307. The nitrogen generator 401 supplies nitrogen to the annealing cylinder 301 and the preheating chamber 105, so that the preheating and annealing processes are in a nitrogen environment, preventing oxidation of the cable 101 surface. One-way valves are installed on the gas pipes 403 to avoid gas backflow.

[0030] Among them, such as Figure 2 As shown, the surface of the housing 102 has several openings 108 to facilitate the transmission of cables 101.

[0031] Among them, such as Figure 1 and Figure 2As shown, a controller 109 is fixedly installed on one side of the housing 102. The controller 109 is connected to the electrical components of the device to facilitate the transmission of commands and control of the device's operation.

[0032] Among them, such as Figure 5 As shown, the preheating chamber 105 is equipped with a conveying roller assembly. The conveying roller assembly consists of a support and several conveying rollers fixed on the support. The conveying roller assembly can be electrically driven or not driven, depending on the actual environment, to facilitate the movement of the conveying cable 101.

[0033] Example 2

[0034] The difference from Example 1 is that, as in Example 2, ... Figure 5 As shown, the outer side of the annealing cylinder 301 is covered with a heat insulation cylinder 308 to prevent rapid heat loss and to prevent high temperature from affecting gear meshing and transmission.

[0035] Among them, such as Figure 5 and Figure 6 As shown, several vent holes are provided at the connection between the annealing cylinder 301 and the support ring 307. A vent groove is provided on the inner side of the support ring 307. The vent holes are evenly distributed along the inner wall of the annealing cylinder 301. The vent groove is connected to the vent holes to avoid uneven nitrogen delivery and facilitate the delivery of nitrogen to the interior of the annealing cylinder 301 through the vent holes. A graphite sealing ring structure is provided on the outer side of the support ring 307 to prevent air leakage.

[0036] During use, one end of the cable 101 is first cleaned by the cleaning brush 206 between the cleaning mechanism 200, the fixing plate 202 and the sliding plate 203 to remove impurities from its surface, ensuring the annealing effect. The cable 101 enters the preheating chamber 105 and is conveyed to the annealing cylinder 301 by the feeding roller group. Several cables 101 pass through multiple rotating annealing cylinders 301. The drive motor 306 drives the annealing cylinders 301 to rotate synchronously through gear transmission. The spiral heating wire 302 inside achieves a uniform heating effect and avoids local overheating. At the same time, the nitrogen filling mechanism 400 injects nitrogen into the preheating chamber 105 and the annealing cylinder 301 through the branch pipe 404 to reduce oxygen contact and prevent oxidation. After annealing, the cable 101 enters the subsequent cooling or processing process.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
