Description

Technical Field

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

[0002] During the production of cables, the extruded cables must go through a cooling and shaping stage to ensure the stability of their shape and size. Next, the cables will enter the vulcanization stage, which is crucial because it can transform the rubber material in the cable insulation layer and protective layer from a linear structure to a three-dimensional cross-linked structure, greatly improving the heat resistance and electrical properties of the cable. During the vulcanization process, the cross-linked bonds formed between the rubber molecular chains further enhance the core performance indicators of the cable, such as tensile strength, wear resistance, tear resistance and elasticity, and comprehensively optimize the overall performance of the cable.

[0003] At present, cable vulcanization operations are usually completed by setting up long-distance vulcanization tubes in the factory. The cable needs to be inserted into the vulcanization tube, and then sulfides such as sulfide gas are injected into the tube for continuous vulcanization treatment. However, in order to ensure that the cable obtains sufficient vulcanization reaction time in the vulcanization tube, the length of the vulcanization tube is designed to be relatively long, which makes the cable threading process time-consuming and laborious. In order to ensure the smooth movement of the cable in the vulcanization tube and reduce friction and wear with the tube wall, the vulcanization tube is also equipped with guide wheels. Although these guide wheels help the cable move smoothly, they make the inner wall of the vulcanization tube no longer flat, thereby increasing the difficulty of cable threading. Therefore, in actual operation, it is often necessary to use tools such as hard rods to assist the cable threading work, which undoubtedly reduces the overall operation efficiency. Summary of the invention

[0004] The present invention aims to solve the technical problem of low efficiency caused by the inconvenience of cable threading along the vulcanizing tube, and provides a vulcanizing production line for cable production. After the butt-joint tube is pushed into the vulcanizing tube to form a passage, it is convenient for cable threading and shortens the cable threading path, ensuring that the cable threading is simple and efficient, and after the butt-joint tube is pulled out, the cable moving 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, an odor sensor and a smoke sensor arranged in the casing and a vulcanization tube supported; both ends of the vulcanization tube are sealed with covers, and a heating belt is arranged on the outer tube wall of the vulcanization tube; a pressure sensor and a temperature sensor are arranged in the vulcanization tube, and a guide wheel group is arranged for lifting, and the guide wheels on both sides of the guide wheel group are respectively provided with gaps between the guide wheels and the covers, and two butt-joint tubes are slidably arranged on the guide wheel group, and the two butt-joint tubes respectively coaxially penetrate the covers and the casing, and are sealed and slidably installed with the covers and the casing; a limiting member is arranged on one side of the butt-joint tube located in the vulcanization tube, and one end of the butt-joint tube located outside the vulcanization tube is sealed with a butt-joint ring by means of a flange, and a sealing ring is arranged on the inner ring wall of the butt-joint ring.

[0006] When the cable is introduced into the vulcanizing tube, the butt-jointed tubes are butt-jointed and connected in the vulcanizing tube to form a complete passage. After the cable passes through the two butt-jointed tubes, the butt-jointed tube is pulled out from the vulcanizing tube so that the cable is completely exposed in the vulcanizing tube, and the position of the guide wheel group is adjusted to support the cable, and the butt-jointed ring on the butt-jointed tube is sealed with the cable through the sealing ring on its inner ring wall, so that the butt-jointed tube and the vulcanizing tube are in a closed environment. After the vulcanizing gas is filled into the vulcanizing tube and the vulcanizing tube is heated by the heating belt, the vulcanizing conditions are formed in the vulcanizing tube and the butt-jointed tube. The cable is vulcanized as the cable moves, 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 the temperature sensor in the vulcanizing tube monitor the vulcanization conditions, and the vulcanizing tube and the interface position of the vulcanizing tube and the butt-jointed tube are located in the casing. The environment in the casing is monitored by the odor sensor and the smoke sensor in the casing, and timely disposal is carried out after leakage occurs in the vulcanizing tube to ensure safety in use.

[0007] To further optimize the technical solution, the cover is sealed and assembled with the vulcanizing tube by means of a flange, a through hole is coaxially arranged on the cover, the vulcanizing tube and the through hole are sealed and slidably installed, and a sealing ring is arranged in the through hole, and the sealing ring is sealed and abutted against the vulcanizing tube.

[0008] The through hole coaxially opened on the cover allows the butt joint tube to move along the vulcanizing tube. A sealing ring is arranged in the through hole to ensure the sealing of the butt joint tube along the cover, as well as the sealing of the assembly of the butt joint tube and the vulcanizing tube, and to ensure the stability of the cable vulcanization environment.

[0009] To further optimize the technical solution, the limiting member includes a clamp clamped on the butt tube, and an annular connecting groove is opened on the outer tube wall of the butt tube, the clamp is arranged in the connecting groove, and the outer wall surface of the clamp protrudes from the outer tube wall of the butt tube.

[0010] The clamp is tightly clamped in the connecting groove on the butt tube, and the outer wall surface of the clamp protrudes from the outer tube wall of the butt tube, thereby preventing the butt tube from slipping off the cover and ensuring the reliability of use. The connecting groove prevents the clamp from detaching from the butt tube and ensures the assembly strength of the clamp.

[0011] To further optimize the technical solution, the casing is provided with docking interfaces that match the two butt joints, the two butt joints are respectively slidably assembled with the docking interfaces, and sealing flanges are provided on the inner and outer sides of each docking interface, the butt joints are slidably assembled with the sealing flanges, and sealing rings are provided in the sealing flanges, and the sealing rings are sealingly abutted against the butt joints.

[0012] A docking port for the butt tube to move is provided on the casing, and sealing flanges are installed on the inner and outer sides of the docking port. The butt tube moves along the sealing flange, and the sealing ring on the sealing flange is in sealing contact with the butt tube, thereby ensuring the sealing of the butt tube and the casing and enhancing the sealing effect.

[0013] To further optimize the technical solution, the guide wheel group includes a straight rod arranged in the vulcanizing tube, the straight rod is raised and lowered in the vulcanizing tube by means of a driving member, and the pressure sensor and the temperature sensor are both arranged on the straight rod; a plurality of circular brackets are arranged on the straight rod along the length direction, and the guide wheel is rotatably mounted on the bottom of the circular bracket; the two butt-jointed tubes are both arranged in the circular bracket and abut against the guide wheel.

[0014] The guide wheel assembly is mainly composed of a straight rod, and a circular bracket supports the guide wheel. The straight rod drives the guide wheel to rise and fall synchronously. By placing the pressure sensor and temperature sensor on the straight rod, it is convenient to disassemble and maintain them, thus ensuring flexibility of use.

[0015] To further optimize the technical solution, the driving member includes a telescopic cylinder assembled on the top of the outer wall of the vulcanizing tube, the output end of the telescopic cylinder is sealed and penetrates into the vulcanizing tube, 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 rise and fall, and adjusts the position of the wheel body to support the butt-jointed pipe or the cable inserted into the vulcanized pipe. The lifting and lowering control of the guide wheel is accurate and simple.

[0017] To further optimize the technical solution, the connecting member includes a flat plate arranged in the vulcanizing tube, the flat plate is fixedly mounted to the output end of the telescopic cylinder, and the flat plate is detachably mounted with the aid of a guide rail assembly and a straight rod.

[0018] The flat plate is detachably mounted with the guide rail assembly and the straight rod, so that the straight rod can be easily installed and disassembled, and the circular bracket, wheel body, pressure sensor and temperature sensor on the straight rod can be maintained and guaranteed, thereby ensuring the reliability of use and improving the flexibility of use.

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

[0020] The circular bracket consists of an "n"-shaped frame body and a supporting shaft, with a simple structure and flexible use.

[0021] To further optimize the technical solution, a notch matching the support shaft is provided at the bottom of the frame, and both ends of the support shaft protrude from the side walls of the frame 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 tightening and fixing the support shaft on the frame body with a locking nut, the assembly operation is simple and the use is flexible and efficient.

[0023] To further optimize the technical solution, a support ring is mounted on one side of the butt-joint pipe outside the vulcanized pipe, a support foot is arranged on the support ring, and a support wheel is rotatably mounted on the support foot.

[0024] After the butt-joint tube is pulled out from the vulcanizing tube, the support wheel is assembled to the butt-joint tube through the support feet and the support ring, so that it moves with the butt-joint tube to ensure the smoothness of pulling the butt-joint tube out of the vulcanizing tube, and supports the butt-joint tube to keep the position of the butt-joint tube stable, ensure the smoothness of the movement of the cable along the butt-joint tube and the vulcanizing tube, and ensure the vulcanization effect.

[0025] The beneficial effects of the present invention are: 1. When inserting the cable into the vulcanizing tube for vulcanization, push the two butt-jointed tubes into the vulcanizing tube to form a complete passage, and then pass the cable through the butt-jointed tubes and then through the vulcanizing tube, so that the cable can be easily threaded. After the butt-jointed tubes are pulled out of the vulcanizing tube, ensure that the cable has enough moving path, ensure the vulcanization effect, and improve the flexibility of use; 2. The sealing ring in the through hole on the cover ensures the sealing of the connection between the butt joint pipe and the vulcanizing pipe. When the cable passes 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, so that a closed space is formed in the butt joint pipe and the vulcanizing pipe. After the vulcanizing pipe is filled with sulfide such as sulfide gas, a vulcanizing environment is formed in the vulcanizing pipe and the butt joint pipe, and the temperature sensor and pressure sensor in the vulcanizing pipe monitor the vulcanizing environment to ensure the vulcanizing effect; 3. After passing through the vulcanizing tube, the butt-joint tube passes outward from the butt-joint port on the casing. Sealing flanges are installed on both the inner and outer sides of the butt-joint port. The sealing ring in the sealing flange ensures the sealing of the butt-joint tube along the sealing flange, and enhances the sealing strength of the connection between the butt-joint tube and the sealing flange. The interface between the butt-joint tube and the vulcanizing tube is located inside the casing. The smoke sensor and odor sensor in the casing monitor the environment inside the casing, so that timely operation and disposal can be carried out after the leakage of sulfide gas, etc., to ensure safety in use; 4. When the butt-joint tube is pushed into the vulcanized tube to thread the cable, it is pushed into the circular bracket and supported by the guide wheel, so that the two butt-joint tubes can be connected smoothly and stably, making the threading of the cable easy. After the butt-joint tube is pulled out of the vulcanized tube, the butt-joint tube is supported by the supporting feet and support wheels inside the butt-joint tube, and does not interfere with the lifting and lowering of the guide wheels inside the vulcanized tube to support the cable, ensuring the smooth movement of the cable and reducing the friction damage of the cable, which is flexible and safe to use.

Please see attached Figure 2 , Attachment Figure 4 , Attachment Figure 7 Two butt-jointed tubes 5 are arranged in the vulcanizing tube 2, and the two butt-jointed tubes 5 are supported by the guide wheel 4 group, that is, the two butt-jointed tubes 5 are respectively supported by the wheel body in the circular bracket 9, and the butt-jointed tubes 5 can move along the vulcanizing tube 2, and coaxially penetrate the covers 3 at both ends of the vulcanizing tube 2.

Please see attached Figure 4 , Attachment Figure 8 , the wheel bodies on both sides of the guide wheel 4 group are provided with gaps from the sealing cover 3. When the butt joint pipe 5 slides outward along the sealing cover 3, it will eventually detach from the guide wheel 4 group, so as not to interfere with the lifting and lowering movement of the guide wheel 4 group, thereby ensuring smooth use. At the same time, a limiting member is provided on the butt joint pipe 5 to prevent the butt joint pipe 5 from slipping off the sealing cover 3 with the wall surface, thereby ensuring reliability of use.

When the cable is vulcanized, the cable is inserted into the butt joint tube 5 through the butt joint ring 501 and passes out through the butt joint ring 501 on another butt joint tube 5. The sealing ring 6 on the butt joint ring 501 is in sealing contact with the cable to ensure the sealing of the vulcanization environment. The specifications of the butt joint ring 501 can be replaced according to the specifications of the cable to ensure the sealing of the butt joint tube 5 and the vulcanizing tube 2. The butt joint tubes 5 on multiple butt joint tubes 5 can be connected through flanges to provide the cable with a sufficiently long vulcanization path to ensure the reliability of vulcanization. Please see attached Figure 4 , Attachment Fig.10 When the cable is vulcanized in the vulcanizing tube 2, a pressure sensor 201 and a temperature sensor 202 are arranged in the vulcanizing tube 2 to monitor the vulcanization environment in the vulcanizing tube 2. The pressure sensor 201 and the temperature sensor 202 can be installed on the straight rod 8 so as to be disassembled and maintained, thereby ensuring flexibility of use. In addition, a plurality of pressure sensors 201 and temperature sensors 202 can be arranged at different positions according to use requirements to ensure accuracy of monitoring results. The pressure sensor 201 and the temperature sensor 202 also transmit detection signals to the central processor to monitor the vulcanization environment in the vulcanizing tube 2. At the same time, a heating belt is arranged on the outer tube wall of the vulcanizing tube 2 (not shown in the figure, the heating belt can be a conventional product on the market, and is arranged on the vulcanizing tube 2 in a winding and pasting manner, and the heating belt is hidden in the figure for a clear expression effect), to heat and insulate the vulcanizing tube 2 to ensure the stability of the vulcanization conditions. The heating belt can be inductively heated by an induction heating coil according to the material of the vulcanizing tube 2, and is efficient to use. The working principle of the vulcanization production line for cable production is as follows: when the cable is introduced into the vulcanization tube 2 for vulcanization operation, the butt-joint rings 501 on the two butt-joint tubes 5 are first removed, and a butt-joint ring 501 with a suitable inner ring diameter is selected according to the specifications of the cable, and the cable is passed through one of the butt-joint rings 501 and then introduced into the butt-joint tube 5 and the vulcanization tube 2. Before the cable is introduced into the butt-joint tube 5, the butt-joint tubes 5 are respectively pushed into the vulcanization tube 2 so that the two butt-joint tubes 5 are butt-jointed and connected. At this time, the guide wheel 4 groups in the vulcanization tube 2 are 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 4 groups all support the butt-joint tube 5 to keep its position stable and ensure the accuracy of its butt-joint. Then the cable is introduced into the butt-joint tube 5, and after passing through the other butt-joint tube 5, the cable passes through the vulcanization tube 2. After the cable passes through the other butt-joint tube 5, the cable passes through another butt-joint ring 501, and the butt-joint rings 501 are respectively sealed and installed on the flanges of the butt-joint tube 5 to seal the space inside the butt-joint tube 5 and the vulcanization tube 2. Then, the butt-joint pipes 5 are pulled out from the vulcanizing tube 2, respectively, so that the cables are fully exposed in the vulcanizing tube 2, thereby improving the smoothness and flexibility of the cable threading and the operation efficiency. After the butt-joint pipes 5 are pulled out, the telescopic cylinder 10 drives the wheel body in the vulcanizing tube 2 to move upward synchronously, and supports the cables, thereby reducing the wear of the cables when they move in the vulcanizing tube 2, and ensuring the smoothness and stability of the cable movement. When the vulcanization operation begins, the vulcanizing gas is injected into the vulcanizing tube 2 and the butt-joint pipes 5 through the joints on the vulcanizing tube 2, and the heating belt heats the vulcanizing tube 2, thereby providing a vulcanization environment for the cable vulcanization operation. The vulcanization environment is monitored by the temperature sensor 202 and the pressure sensor 201 in the vulcanizing tube 2, and the vulcanization time of the cable in the vulcanizing tube 2 is controlled by controlling the moving speed of the cable to ensure the vulcanization effect of the cable. The butt-joint pipes 5 can be connected by flange sealing by increasing the number of vulcanizing tubes 2, thereby extending the moving path of the cable and controlling the vulcanization time of the cable. When the cable is vulcanized, the cabinet door is closed to place the casing 1 in a closed space. At the same time, the odor sensor 101 and the smoke sensor 102 in the casing 1 monitor the environmental conditions in the casing 1, and after the sulfide gas leaks, the controller promptly issues an alarm so that timely disposal can be carried out to ensure the safety of the vulcanization operation.
