Description

Technical Field

[0001] The present invention belongs to the field of mechanical equipment, relates to the field of vulcanization equipment, and particularly relates to a vulcanization production line for cable production. Background Art

[0002] In the process of cable production, the extruded cable must go through a cooling and shaping stage to ensure the stability of its shape and size. Immediately afterwards, the cable enters the vulcanization stage, which is crucial because it can transform the rubber substances in the cable insulation layer and protective layer from a linear structure into a three-dimensional cross-linked structure, greatly enhancing the heat resistance and electrical performance of the cable. During the vulcanization process, the cross-linking bonds formed between rubber molecular chains further enhance the core performance indicators of the cable such as tensile strength, abrasion resistance, tear resistance, and elasticity, comprehensively optimizing the overall performance of the cable.

[0003] Currently, cable vulcanization operations are usually completed by installing long-distance vulcanization pipes in the factory building. The cable needs to be threaded into the vulcanization pipe, and then sulfides such as vulcanization gas are injected into the pipe for continuous vulcanization treatment. However, in order to ensure that the cable has sufficient vulcanization reaction time in the vulcanization pipe, the length of the vulcanization pipe is designed to be relatively long, which makes the cable threading process time-consuming and laborious. To ensure the smooth movement of the cable in the vulcanization pipe and reduce friction and wear with the pipe wall, guide wheels are also installed in the vulcanization pipe. Although these guide wheels help the cable move smoothly, they make the inner wall of the vulcanization pipe uneven, thus increasing the difficulty of cable threading. Therefore, in actual operation, tools such as rigid rods often need to be used to assist the cable threading work, which undoubtedly reduces the overall operation efficiency. Summary of the Invention

[0004] The present invention is to solve the technical problem of low efficiency caused by the inconvenient threading of the cable along the vulcanization pipe, and provides a vulcanization production line for cable production. After the docking pipe is pushed into the vulcanization pipe to form a passage, it is convenient for the cable to be threaded, and the cable threading path is shortened, ensuring that the cable threading is simple and efficient. Moreover, after the docking pipe is pulled out, the cable movement path and vulcanization time are guaranteed.

[0005] The technical solution adopted by the present invention is: to provide a vulcanization production line for cable production, including a casing provided with a cabinet door, in which an odor sensor, a smoke sensor and a vulcanization tube are arranged; the two ends of the vulcanization tube are hermetically assembled with covers, and a heating belt is arranged on the outer wall of the vulcanization tube; a pressure sensor, a temperature sensor are arranged in the vulcanization tube, and a guide wheel group is arranged in a lifting manner. There are gaps between the guide wheels on both sides of the guide wheel group and the covers respectively. Two butting pipes slide on the guide wheel group. The two butting pipes respectively penetrate through the covers and the casing coaxially and are hermetically and slidably installed with the covers and the casing; a limiting member is arranged on one side of the butting pipe located inside the vulcanization tube, and a butting ring is hermetically assembled with a flange at one end of the butting pipe located outside the vulcanization tube, and a sealing ring is arranged on the inner ring wall of the butting ring.

[0006] When introducing the cable into the vulcanization tube, the butting pipes are butted and communicated inside the vulcanization tube to form a complete passage. After the cable passes through the two butting pipes, the butting pipes are pulled out from the vulcanization tube, so that the cable is completely exposed inside the vulcanization tube. By adjusting the position of the guide wheel group, the cable is supported, and the butting ring on the butting pipe is in sealed contact with the cable through the sealing ring on its inner ring wall, so that the inside of the butting pipe and the vulcanization tube is in a closed environment. After injecting vulcanization gas into the vulcanization tube and heating the vulcanization tube through the heating belt, vulcanization conditions are formed inside the vulcanization tube and the butting pipe. As the cable moves, vulcanization operation is carried out on the cable, and the vulcanization reaction time is controlled by controlling the moving speed of the cable to ensure the vulcanization effect. At the same time, the pressure sensor and temperature sensor inside the vulcanization tube monitor the vulcanization conditions, and the vulcanization tube and the interface position between the vulcanization tube and the butting pipe are located inside the casing. The odor sensor and smoke sensor inside the casing monitor the environment inside the casing, and timely disposal is carried out after leakage occurs inside the vulcanization tube to ensure the use safety.

[0007] To further optimize the technical solution, the cover is hermetically assembled with the vulcanization tube by a flange. A through hole is coaxially arranged on the cover, and the two butting pipes are hermetically and slidably installed with the through hole respectively, and a sealing ring is arranged in the through hole, and the sealing ring is in sealed contact with the butting pipe.

[0008] The through hole coaxially opened on the cover allows the butting pipe to move along the vulcanization tube. The sealing ring arranged in the through hole ensures the sealing performance of the butting pipe moving along the cover and the sealing performance of the assembly of the butting pipe and the vulcanization tube, and ensures the stability of the cable vulcanization environment.

[0009] To further optimize the technical solution, the limiting member includes a hoop tightened on the butting pipe, and an annular connecting groove is opened on the outer wall of the butting pipe, and the hoop is arranged in the connecting groove, and the outer wall surface of the hoop protrudes from the outer wall of the butting pipe.

[0010] The hoop is fastened in the connection groove on the butt joint pipe, and the outer wall surface of the hoop protrudes from the outer pipe wall of the butt joint pipe, thereby preventing the butt joint pipe from slipping off the cover, ensuring the reliability of use, and the connection groove prevents the hoop from detaching from the butt joint pipe, ensuring the assembly strength of the hoop.

[0011] To further optimize this technical solution, the machine shell is provided with docking ports that match the two butt joint pipes. The two butt joint pipes are respectively slidably assembled with the docking ports, and sealing flanges are provided on both the inner and outer sides of each docking port. The butt joint pipes are slidably assembled with the sealing flanges, and sealing rings are provided inside the sealing flanges. The sealing rings are in sealing contact with the butt joint pipes.

[0012] A docking port for the movement of the butt joint pipe is opened on the machine shell. Sealing flanges are installed on both the inner and outer sides of the docking port. The butt joint pipe moves along the sealing flange, and the sealing ring on the sealing flange is in sealing contact with the butt joint pipe, thereby ensuring the sealing performance of the assembly of the butt joint pipe and the machine shell and enhancing the sealing effect.

[0013] To further optimize this technical solution, the guide wheel group includes a straight rod disposed inside the vulcanization pipe. The straight rod is vertically arranged in the vulcanization pipe by means of a driving member, and both the pressure sensor and the temperature sensor are disposed on the straight rod; a plurality of loop brackets are arranged along the length direction on the straight rod, and the guide wheels are rotatably mounted at the bottom of the loop brackets; both butt joint pipes are disposed inside the loop brackets and are in contact with the guide wheels.

[0014] The guide wheel group takes the straight rod as the main body, the loop brackets support the guide wheels, the straight rod drives the guide wheels to lift synchronously, and by arranging the pressure sensor and the temperature sensor on the straight rod, it is convenient for disassembly, installation and maintenance, ensuring the flexibility of use.

[0015] To further optimize this technical solution, the driving member includes a telescopic cylinder assembled on the top of the outer pipe wall of the vulcanization pipe. The output end of the telescopic cylinder penetrates into the vulcanization pipe in a sealed manner, and the output end of the telescopic cylinder is fixedly installed with the straight rod by means of a connecting member.

[0016] The telescopic cylinder drives the straight rod to lift, adjusting the position of the wheel body so as to support the butt joint pipe or the cable penetrating into the vulcanization pipe. The lifting control of the guide wheel is accurate and simple.

[0017] To further optimize this technical solution, the connecting member includes a flat plate disposed inside the vulcanization pipe. The flat plate is fixedly installed with the output end of the telescopic cylinder, and the flat plate is detachably installed with the straight rod by means of a guide rail assembly.

[0018] The detachable installation of the flat plate and the straight rod by means of the guide rail assembly facilitates the installation and disassembly of the straight rod, enabling maintenance guarantees for the loop brackets, wheel bodies, pressure sensors and temperature sensors, etc. on the straight rod, ensuring the reliability of use and improving the flexibility of use.

[0019] To further optimize this technical solution, the loop-shaped bracket includes an "n"-shaped frame body. A support shaft is detachably assembled at the bottom of the frame body, and a guide wheel is rotatably assembled on the support shaft.

[0020] The loop-shaped bracket is composed of an "n"-shaped frame body and a support shaft, with a simple structure and flexible use.

[0021] To further optimize this technical solution, a notch matching the support shaft is provided at the bottom of the frame body. Both ends of the support shaft protrude from the side walls of the frame body respectively and are threadedly connected with locking nuts.

[0022] By pushing the support shaft on the wheel body into the notch on the frame body and using the locking nut to tighten and fix the support shaft on the frame body, the assembly operation is simple, and the use is flexible and efficient.

[0023] To further optimize this technical solution, a support ring is sleeved on one side of the butt joint pipe outside the vulcanizing pipe. Support feet are provided on the support ring, and support wheels are rotatably installed on the support feet.

[0024] After the butt joint pipe is pulled out of the vulcanizing pipe, the support wheel is assembled onto the butt joint pipe through the support feet and the support ring, so as to move along with the butt joint pipe, ensuring the smoothness of pulling the butt joint pipe out of the vulcanizing pipe, supporting the butt joint pipe, keeping the position of the butt joint pipe stable, ensuring the smoothness of the cable moving along the butt joint pipe and the vulcanizing pipe, and ensuring the vulcanizing effect.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. When preparing for vulcanization operation by threading a cable into the vulcanizing pipe, by pushing the two butt joint pipes into the vulcanizing pipe respectively to connect and communicate the pipes to form a complete path, and then making the cable penetrate through the butt joint pipe and then through the vulcanizing pipe, the cable threading is simple. After pulling the butt joint pipe out of the vulcanizing pipe, it ensures that the cable has enough moving paths, ensures the vulcanizing effect, and improves the use flexibility;

[0027] 2. The sealing ring in the through hole of the cover ensures the sealing performance of the connection between the butt joint pipe and the vulcanizing pipe. When the cable penetrates through the butt joint pipe and the vulcanizing pipe, the cable passes through the butt joint ring and is sealed and abutted by the sealing ring on the butt joint ring, forming a closed space inside the butt joint pipe and the vulcanizing pipe. After injecting vulcanizing substances such as vulcanizing gas into the vulcanizing pipe, a vulcanizing environment is formed inside the vulcanizing pipe and the butt joint pipe, and the temperature sensor and pressure sensor inside the vulcanizing pipe monitor the vulcanizing environment to ensure the vulcanizing effect;

[0028] 3. After passing through the vulcanizing pipe, the docking pipe passes outwards through the docking port on the casing. Sealing flanges are installed on both the inner and outer sides of the docking port. The sealing rings inside the sealing flanges ensure the sealing performance of the docking pipe moving along the sealing flanges, enhancing the sealing strength of the connection between the docking pipe and the sealing flanges. Moreover, the interface between the docking pipe and the vulcanizing pipe is located inside the casing. The smoke sensor and odor sensor inside the casing monitor the environment inside the casing. After the leakage of vulcanizing gas and the like, timely operation and disposal can be carried out to ensure the safety of use.

[0029] 4. When the docking pipe is pushed into the vulcanizing pipe to thread the cable, the docking pipe is pushed into the loop-shaped bracket and supported by the guide wheels, making the docking of the two docking pipes smooth and stable, simplifying the threading of the cable. After pulling the docking pipe out of the vulcanizing pipe, it is supported by the inner feet and support wheels inside the docking pipe, and does not interfere with the lifting of the guide wheels inside the vulcanizing pipe to support the cable, ensuring the smooth movement of the cable and reducing the friction and damage of the cable, making it flexible and safe to use.

The heating tape can be inductively heated by an induction heating coil according to the material of the vulcanizing pipe 2, with high efficiency;

[0053] The working principle of the vulcanization production line for cable production is as follows: When introducing the cable into the vulcanization tube 2 for vulcanization operation, first remove the docking rings 501 on the two docking pipes 5, select a docking ring 501 with a suitable inner ring diameter according to the cable specifications, and introduce the cable into the docking pipe 5 and the vulcanization tube 2 after passing the cable through one of the docking rings 501. Before the cable is introduced into the docking pipe 5, push the docking pipes 5 into the vulcanization tube 2 respectively to make the two docking pipes 5 dock and communicate. At this time, the guide wheel group in the vulcanization tube 2 is driven by the telescopic cylinder 10 to be located at the bottom of the vulcanization tube 2, and the wheel bodies of the guide wheel group support the docking pipe 5 to keep its position stable and ensure the accuracy of its docking. Then introduce the cable into the docking pipe 5, and after passing through the other docking pipe 5, make the cable penetrate the vulcanization tube 2. And after the cable passes through the other docking pipe 5, make the cable pass through the other docking ring 501, and seal and install the docking ring 501 on the flange of the docking pipe 5 respectively to seal the space in the docking pipe 5 and the vulcanization tube 2. Then pull out the docking pipes 5 from the vulcanization tube 2 respectively, so that the cable is fully exposed in the vulcanization tube 2, improving the smoothness and flexibility of cable threading and the operation efficiency. After the docking pipe 5 is pulled out, the telescopic cylinder 10 drives the wheel bodies in the vulcanization tube 2 to move up synchronously and support the cable, reducing the wear of the cable moving in the vulcanization tube 2 and ensuring the smoothness and stability of the cable movement. When starting the vulcanization operation, vulcanization gas and the like are injected into the vulcanization tube 2 and the docking pipe 5 through the joints on the vulcanization tube 2, and the heating belt heats the vulcanization tube 2, thereby providing a vulcanization environment for the cable vulcanization operation. And monitor the vulcanization environment through the temperature sensor 202 and pressure sensor 201 in the vulcanization tube 2, and control the vulcanization time of the cable in the vulcanization tube 2 by controlling the moving speed of the cable, ensuring the vulcanization effect of the cable, and by increasing the number of vulcanization tubes 2, the docking pipes 5 are hermetically connected by means of flanges to extend the moving path of the cable and control the vulcanization time of the cable. When carrying out the cable vulcanization operation, the cabinet door is closed to make the machine shell 1 in a closed space. At the same time, the odor sensor 101 and smoke sensor 102 in the machine shell 1 monitor the environmental state in the machine shell 1, and after the vulcanization gas leaks, an alarm is given in time through the controller for timely handling to ensure the safety of the vulcanization operation.
