Description

Technical Field

[0001] The invention relates to the technical field of wire and cable manufacturing, in particular 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. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulating cores, and their respective coatings, total 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 the development of society, people's requirements for wires and cables are getting higher and higher, and the application of a cable sheath drying device is becoming more and more extensive. Therefore, the demand for a cable sheath drying device 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 trough, followed by a blow-drying process to ensure product quality; however, the existing blow-drying device has a fixed size of an annular air outlet duct, which makes it unable to flexibly adapt to the drying needs of cables of different specifications. For thinner cables, an overly large air outlet may cause the airflow to be too dispersed, resulting in low drying efficiency, and may even fail to completely dry the moisture on the cable surface; on the other hand, for thicker cables, an overly small air outlet may limit the amount of airflow, resulting in an unsatisfactory drying effect and increasing the energy consumption of the equipment. Summary of the invention

[0004] The object of the present invention is to provide a cable sheath drying device, which is used to solve the problem that when the existing device dries the cable sheath, the annular air outlet pipe has a fixed size and cannot adapt to different cable specifications. The thin cable has a low drying efficiency due to the large air outlet, and the thick cable has a small air outlet that limits the airflow, which affects the drying effect and increases energy consumption.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cable sheath drying device, comprising a bracket, two air inlet assemblies arranged on the bracket and spaced apart, and an annular blow dryer arranged on the bracket, wherein the two air inlet assemblies are both connected to the annular blow dryer, and the annular blow dryer comprises two elastic outer air ring tubes arranged in a relative manner, a first air inlet joint connected to the outer side of the elastic outer air ring tube, a plurality of first air outlet holes arranged on the inner side of the elastic outer air ring tube and spaced apart, two elastic inner air outlet ring tubes arranged in a relative manner, and a second air inlet joint connected to the outer side of the elastic inner air outlet ring tube. The air outlet pipe is connected with the air inlet pipe of the elastic force inner side, and the air inlet pipe is connected with the air inlet pipe of the elastic force inner side. The air outlet pipe is connected with the air inlet pipe of the elastic force inner side, and the air inlet pipe is connected with the air inlet pipe of the elastic force inner side. The air outlet pipe is connected with the air inlet pipe of the elastic force inner side, and the air outlet pipe is connected with the air inlet pipe of the elastic force outer side, and the ...

[0007] Furthermore, the bracket includes a fixed frame, two vertical plates connected to the lower side of the fixed frame and arranged at intervals, a bottom plate connected to the lower sides of the two vertical plates, ear plates respectively connected to both sides of the bottom plate, and a plurality of mounting holes provided on the ear plates, the two first electric push rods, two Y-shaped joints and 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 vertical plate.

[0008] Furthermore, the inner wall of the elastic outer air outlet ring tube is provided with two sliding grooves arranged at intervals, and the interior of the sliding groove is slidably matched with a sliding block connected to the outer side of the elastic inner air outlet ring tube.

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

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

[0011] Compared with the prior art, the present invention has the following beneficial effects: When performing a blow-drying process on the cable sheath, the present invention combines the coordinated work of two first electric push rods, two second electric push rods, two elastic outer air ring tubes, two elastic inner air ring tubes, etc., so that the size of the air outlet ring tube composed of the two elastic outer air ring tubes and the two elastic inner air outlet ring tubes can be flexibly adjusted to meet the blow-drying requirements of cable sheaths of different specifications; thereby, the device solves two major problems faced by traditional blow-drying devices: on the one hand, for thin cables, the problem of low blow-drying efficiency caused by excessively large air outlets is avoided; on the other hand, for thick cables, the disadvantage that too small air outlets may limit airflow, thereby affecting the blow-drying effect and increasing energy consumption is overcome. By adjusting the size of the annular blow dryer, the device can achieve efficient blow-drying of cable sheaths of different specifications, thereby improving operating efficiency and blow-drying quality.

An electric push rod 6 and two second electric push rods 7 are started, and the two first electric push rods 6 work together to drive the two elastic outer air ring tubes 2 to move away from or close to 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 mode. In this adjustment, the two ends of the elastic inner air ring tube 3 slide outward or retract inward at one end of the inner part of the elastic outer air ring tube 2, thereby adjusting the inner diameter of the air outlet ring tube composed of the two elastic outer air ring tubes 2 and the two elastic inner air outlet ring tubes 3 to meet the needs of drying cable sheaths of different specifications; after the adjustment is completed, the air compressor is started, and the dry compressed air passes through the two inlets The air component 1 respectively enters into the interior of two elastic outer air ring tubes 2 and two elastic inner air ring tubes 3, and blows out through multiple first air outlet holes 19 and multiple second air outlet holes 20 to dry the moisture on the surface of the cable sheath passing through; thus, the device solves the 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 too small air outlets may limit airflow, thereby affecting the drying effect and increasing energy consumption. By adjusting the size of the annular dryer, the device can achieve efficient drying of cable sheaths of different specifications, thereby improving operating efficiency and drying quality.

[0015] The air intake assembly 1 includes an air pressure regulator 8 connected to the bracket, a connecting pipe 12 and an air pipe 9 respectively connected to both ends of the air pressure regulator 8, a Y-type joint 10 connected to one end of the air pipe 9, and two branch pipes 11 connected to the Y-type joint 10, one end of the two branch pipes 11 is respectively connected to the outer wall of the first air intake joint 4 and the second air intake joint 5, and the Y-type joint 10 is connected to the bracket; the air pressure during the blow-drying process is conveniently adjusted by the air pressure regulator 8; the connecting pipe 12 is connected to an external air compressor; the dry and compressed air generated by the air compressor The compressed air is transmitted to the air pipe 9 through the connecting pipe 12, and then guided to the inside of the Y-type joint 10, where it is split and transported through two branch pipes 11, wherein one airflow enters the elastic outer air ring tube 2 through the first air inlet joint 4, and the other airflow flows into the elastic inner air outlet ring tube 3 through the second air inlet joint 5; this ensures that the dry compressed air can be efficiently and evenly distributed to the elastic outer air ring tube 2 and the elastic inner air outlet ring tube 3, providing a sufficient power source for the subsequent drying operation of the cable sheath.

[0016] The bracket includes a fixed frame 13, two vertical plates 14 connected to the lower side of the fixed frame 13 and arranged at intervals, a bottom plate 15 connected to the lower sides of the two vertical plates 14, ear plates 16 respectively connected to the two sides of the bottom plate 15, and a plurality of mounting holes provided on the ear plates 16. The two first electric push rods 6, the two Y-shaped joints 10 and the two second electric push rods 7 are all connected to the outer wall of the fixed frame 13, and the air pressure regulator 8 is connected to the vertical plate 14. The fixed frame 13 facilitates the installation and fixation of the two first electric push rods 6, the two Y-shaped joints 10 and the two second electric push rods 7.

[0017] The inner wall of the elastic outer air outlet ring tube 2 is provided with two interval-arranged slide grooves 17, and the inner sliding groove 17 is slidably matched with a slider 18 connected to the outer side of the elastic inner air outlet ring tube 3; when the elastic inner air outlet ring tube 3 slides in the elastic outer air outlet ring tube 2, the slider 18 connected to the outer side of the elastic inner air outlet ring tube 3 slides in the slide groove 17, thereby limiting the elastic inner air outlet ring tube 3 during the process of sliding outward in the elastic outer air outlet ring tube 2, preventing the elastic inner air outlet ring tube 3 from detaching from the elastic outer air outlet ring tube 2.

[0018] A sealing ring 21 is provided between one end of the elastic outer air outlet ring tube 2 and the elastic inner air outlet ring tube 3 ; the sealing ring 21 improves the sealing performance between one end of the elastic outer air outlet ring tube 2 and the elastic inner air outlet ring tube 3 .

[0019] The elastic outer air-exiting ring tube 2 and the elastic inner air-exiting ring tube 3 are both made of PVC, so that the elastic inner air-exiting ring tube 3 can be extended and retracted in the elastic outer air-exiting ring tube 2 .

[0020] Working principle: In the process of drying the cable sheath, for cable sheaths of different specifications, the size of the annular dryer is first adjusted. During the adjustment, the controller instructs the two first electric push rods 6 and the two second electric push rods 7 to start. The two first electric push rods 6 work together to drive the two elastic outer air ring tubes 2 to move away from or close to each other. At the same time, the two second electric push rods 7 also drive the two elastic inner air outlet ring tubes 3 to move in the same mode. In this adjustment, the two ends of the elastic inner air outlet ring tube 3 slide outward or retract inward at one end of the inner part of the elastic outer air ring tube 2, and the slider 18 connected to the outer side of the elastic inner air outlet ring tube 3 slides in the slide groove 17, thereby adjusting the inner diameter of the air outlet ring tube composed of the two elastic outer air ring tubes 2 and the two elastic inner air outlet ring tubes 3 to meet the needs of drying cable sheaths of different specifications. After the adjustment, start the air compressor to dry and compress. The air is transmitted to the air pipe 9 through the connecting pipe 12, and then guided to the inside of the Y-type joint 10, and is divided at the Y-type joint 10 and transported through two branch pipes 11 respectively, wherein one airflow enters the elastic outer air ring tube 2 through the first air inlet joint 4, and the other airflow flows into the elastic inner air outlet ring tube 3 through the second air inlet joint 5, and is blown out through multiple first air outlet holes 19 and multiple second air outlet holes 20, so as to dry the moisture on the surface of the cable sheath passing through; thus, the device solves the 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 too small air outlets may limit airflow, thereby affecting the drying effect and increasing energy consumption. By adjusting the size of the annular dryer, the device can achieve efficient drying of cable sheaths of different specifications, thereby improving operating efficiency and drying quality.
