Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing technology, specifically to a cable sheath drying device. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible covering layers, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors. They are wire products used to transmit electrical energy, information, and realize electromagnetic energy conversion. With social development, people's requirements for wires and cables are getting higher and higher, and the application of cable sheath drying devices is becoming more and more widespread. Therefore, the demand for cable sheath drying devices is growing.

[0003] Currently, in the manufacturing process of wires and cables, an important step after extruding the cable sheath is to cool it through a cooling water tank, followed by drying to ensure product quality. However, existing drying devices have fixed-size annular air outlets, which makes them unable to flexibly adapt to the drying needs of cables of different specifications. For thinner cables, an excessively large outlet may cause the airflow to be too dispersed, resulting in low drying efficiency and possibly failing to completely dry the moisture on the cable surface. On the other hand, for thicker cables, an excessively small outlet may limit the airflow, resulting in unsatisfactory drying effects and increased energy consumption of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a cable sheath drying device to solve the problems of existing devices drying cable sheaths, which cannot adapt to different cable specifications due to the fixed size of the annular air outlet. Thin cables have low drying efficiency due to the large air outlet, while thick cables have airflow restricted due to the small air outlet, which affects the drying effect and increases energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable sheath drying device, comprising a support, two air inlet components arranged at intervals on the support, and an annular dryer arranged on the support. Both air inlet components are connected to the annular dryer. The annular dryer includes two elastic outgoing air ring pipes arranged opposite each other, a first air inlet connector connected to the outer side of the elastic outgoing air ring pipes, a plurality of first air outlet holes arranged at intervals on the inner side of the elastic outgoing air ring pipes, two elastic inner air outlet ring pipes arranged opposite each other, and a second air inlet connector connected to the outer side of the elastic inner air outlet ring pipes. The system includes an air connector, multiple second air outlets spaced apart inside the elastic inner air outlet ring tube, two first electric push rods and two second electric push rods mounted on a bracket. The output ends of the two first electric push rods are respectively connected to one end of the two first air inlets, and the output ends of the two second electric push rods are respectively connected to one end of the two second air inlets. Both the elastic outer air outlet ring tube and the elastic inner air outlet ring tube are hollow structures. The two ends of the elastic inner air outlet ring tube are respectively slidably fitted with the inner walls of the two elastic outer air outlet ring tubes. The air inlet assembly is connected to the first air inlet connector and the second air inlet connector.

[0006] Furthermore, the air intake assembly includes a pressure regulator connected to the bracket, a connecting pipe and an air pipe respectively connected to both ends of the pressure regulator, a Y-type connector connected to one end of the air pipe, and two branch pipes connected to the Y-type connector. One end of each of the two branch pipes is connected to the outer wall of the first air intake connector and the second air intake connector respectively. The Y-type connector is connected to the bracket.

[0007] Furthermore, the bracket includes a fixed frame, two upright plates connected to the lower side of the fixed frame and spaced apart, a base plate connected to the lower side of the two upright plates, ear plates connected to both sides of the base plate respectively, and multiple mounting holes provided on the ear plates. The two first electric push rods, the two Y-type connectors and the two second electric push rods are all connected to the outer wall of the fixed frame, and the air pressure regulator is connected to the upright plates.

[0008] Furthermore, the inner wall of the elastic outgoing air ring tube is provided with two spaced-apart sliding grooves, and the sliding grooves are slidably fitted with sliders connected to the outer side of the elastic inner air ring tube.

[0009] Furthermore, a sealing ring is provided between one end of the elastic outward air ring tube and the elastic inner air ring tube.

[0010] Furthermore, both the elastic outer air ring tube and the elastic inner air ring tube are made of PVC.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] This invention, when drying cable sheaths, combines the coordinated operation of two first electric push rods, two second electric push rods, two elastic outward air ring tubes, and two elastic inner air ring tubes. This allows for flexible adjustment of the size of the air ring tubes (comprising the two elastic outward air ring tubes and the two elastic inner air ring tubes) to suit the drying needs of cable sheaths of different specifications. Furthermore, this device solves two major problems faced by traditional drying devices: firstly, for thin cables, it avoids the problem of low drying efficiency caused by excessively large air outlets; secondly, for thick cables, it overcomes the drawback of excessively small air outlets potentially restricting airflow, thus affecting drying effect and increasing energy consumption. By adjusting the size of the ring dryer, this device can achieve efficient drying of cable sheaths of different specifications, improving work efficiency and drying quality.

[0016] Please see Figure 1-2A cable sheath drying device includes a bracket, two air inlet components 1 arranged at intervals on the bracket, and an annular dryer arranged on the bracket. Both air inlet components 1 are connected to the annular dryer. The annular dryer includes two elastic outgoing air ring pipes 2 arranged opposite to each other, a first air inlet connector 4 connected to the outside of the elastic outgoing air ring pipes 2, a plurality of first air outlet holes 19 arranged at intervals on the inner side of the elastic outgoing air ring pipes 2, two elastic inner air outgoing air ring pipes 3 arranged opposite to each other, a second air inlet connector 5 connected to the outside of the elastic inner air outgoing air ring pipes 3, a plurality of second air outlet holes 20 arranged at intervals on the inner side of the elastic inner air outgoing air ring pipes 3, and two first electric... Push rod 6 and two second electric push rods 7, the output ends of the two first electric push rods 6 are respectively connected to one end of the two first air inlet connectors 4, and the output ends of the two second electric push rods 7 are respectively connected to one end of the two second air inlet connectors 5. The elastic outgoing air ring tube 2 and the elastic inner air ring tube 3 are both hollow structures. The two ends of the elastic inner air ring tube 3 are respectively slidably engaged with the inner walls of the two elastic outgoing air ring tubes 2. The air intake assembly 1 is connected to the first air inlet connector 4 and the second air inlet connector 5; the air intake assembly 1 is connected to an external air compressor; in the cable sheath drying process, for cable sheaths of different specifications, the size of the ring dryer is first adjusted. During adjustment, the controller commands the two second electric push rods 6 and 7 to adjust the size of the ring dryer. One electric actuator 6 and two second electric actuators 7 are activated. The two first electric actuators 6 work together to drive the two elastic outgoing air ring tubes 2 to move away from or towards each other. At the same time, the two second electric actuators 7 also drive the two elastic inner air ring tubes 3 to move in the same pattern. During this adjustment, the two ends of the elastic inner air ring tube 3 slide outward or retract inward at one end inside the elastic outgoing air ring tube 2, thereby adjusting the inner diameter of the air ring tube formed by the two elastic outgoing air ring tubes 2 and the two elastic inner air ring tubes 3 to adapt to the drying needs of cable sheaths of different specifications. After the adjustment is completed, the air compressor is started, and the dry compressed air passes through two inlets. The air assembly 1 enters the interior of two elastic outgoing air ring tubes 2 and two elastic inner air ring tubes 3 respectively, and is blown out through multiple first air outlets 19 and multiple second air outlets 20 to dry the moisture on the surface of the cable sheath. Thus, this device solves two major problems faced by traditional drying devices: on the one hand, for thin cables, it avoids the problem of low drying efficiency caused by excessively large air outlets; on the other hand, for thick cables, it overcomes the disadvantage that excessively small air outlets may restrict airflow, thereby affecting the drying effect and increasing energy consumption. By adjusting the size of the ring dryer, this device can achieve efficient drying of cable sheaths of different specifications, improving work efficiency and drying quality.

[0017] The air intake assembly 1 includes a pressure regulator 8 connected to a bracket, a connecting pipe 12 and an air pipe 9 respectively connected to both ends of the pressure regulator 8, a Y-type connector 10 connected to one end of the air pipe 9, and two branch pipes 11 connected to the Y-type connector 10. One end of each branch pipe 11 is connected to the outer wall of the first air intake connector 4 and the second air intake connector 5 respectively. The Y-type connector 10 is connected to the bracket. The pressure regulator 8 facilitates the adjustment of the air pressure during the drying process. The connecting pipe 12 enables connection to an external air compressor. The air compressor generates dry and pressurized air. Compressed air is transmitted to the air pipe 9 via the connector 12, and then guided into the interior of the Y-connector 10. At the Y-connector 10, the air is split and transported through two branch pipes 11. One airflow enters the elastic outgoing air ring pipe 2 through the first air inlet connector 4, while the other airflow flows into the elastic inner air ring pipe 3 through the second air inlet connector 5. This ensures that the dry compressed air can be efficiently and evenly distributed to the elastic outgoing air ring pipe 2 and the elastic inner air ring pipe 3, providing sufficient power for the subsequent drying operation of the cable sheath.

[0018] The bracket includes a fixed frame 13, two upright plates 14 connected to the lower side of the fixed frame 13 and spaced apart, a base plate 15 connected to the lower side of the two upright plates 14, ear plates 16 connected to both sides of the base plate 15, and multiple mounting holes on the ear plates 16. Two first electric push rods 6, two Y-type connectors 10, and two second electric push rods 7 are all connected to the outer wall of the fixed frame 13, and a pneumatic pressure regulator 8 is connected to the upright plates 14. The fixed frame 13 facilitates the installation and fixing of the two first electric push rods 6, the two Y-type connectors 10, and the two second electric push rods 7. The two upright plates 14 support and fix the fixed frame 13 while facilitating the installation of the pneumatic pressure regulator 8. The two ear plates 16 and their multiple mounting holes facilitate the installation of the device into the production line.

[0019] The inner wall of the elastic outward air ring tube 2 is provided with two spaced-apart sliding grooves 17. The sliding grooves 17 are slidably fitted with sliders 18 connected to the outer side of the elastic inner air ring tube 3. When the elastic inner air ring tube 3 slides inside the elastic outward air ring tube 2, the sliders 18 connected to the outer side of the elastic inner air ring tube 3 slide inside the sliding grooves 17, thereby limiting the elastic inner air ring tube 3 as it slides outward inside the elastic outward air ring tube 2, preventing the elastic inner air ring tube 3 from detaching from the elastic outward air ring tube 2.

[0020] A sealing ring 21 is provided between one end of the elastic outgoing air ring pipe 2 and the elastic inner air ring pipe 3; the sealing ring 21 improves the sealing performance between one end of the elastic outgoing air ring pipe 2 and the elastic inner air ring pipe 3.

[0021] Both the elastic outward air ring tube 2 and the elastic inward air ring tube 3 are made of PVC, which facilitates the extension and retraction of the elastic inward air ring tube 3 within the elastic outward air ring tube 2.

[0022] Working Principle: In the cable sheath drying process, for cable sheaths of different specifications, the size of the annular dryer is first adjusted. During adjustment, the controller commands two first electric push rods 6 and two second electric push rods 7 to start. The two first electric push rods 6 work together to drive the two elastic outgoing air ring tubes 2 to move away from or towards each other. At the same time, the two second electric push rods 7 also drive the two elastic inner air ring tubes 3 to move in the same pattern. In this adjustment, the two ends of the elastic inner air ring tube 3 slide outward or retract inward at one end inside the elastic outgoing air ring tube 2, respectively. The slider 18 connected to the outside of the elastic inner air ring tube 3 slides in the groove 17, thereby adjusting the inner diameter of the air ring tube formed by the two elastic outgoing air ring tubes 2 and the two elastic inner air ring tubes 3 to adapt to the drying needs of cable sheaths of different specifications. After adjustment, the air compressor is started to dry and compress the air. Air is transmitted through the connector 12 to the air pipe 9, and then guided into the interior of the Y-connector 10. At the Y-connector 10, the air is split and transported through two branch pipes 11. One airflow enters the elastic outgoing air ring pipe 2 through the first air inlet connector 4, while the other airflow flows into the elastic inner air ring pipe 3 through the second air inlet connector 5 and is blown out through multiple first air outlets 19 and multiple second air outlets 20, drying the moisture on the surface of the cable sheath. Thus, this device solves two major problems faced by traditional drying devices: on the one hand, for thin cables, it avoids the problem of low drying efficiency caused by excessively large air outlets; on the other hand, for thick cables, it overcomes the disadvantage that excessively small air outlets may restrict airflow, thereby affecting the drying effect and increasing energy consumption. By adjusting the size of the ring dryer, this device can achieve efficient drying of cable sheaths of different specifications, improving work efficiency and drying quality.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
