Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire processing, in particular to a processing device and method of halogen-free low-smoke ultraviolet irradiation cross-linked polyolefin insulated energy-saving wire. BACKGROUND

[0002] With the rapid development of power engineering, rail transportation, building wiring and other fields, the safety performance, environmental protection requirements and energy-saving characteristics of the wire are put forward more stringent standards. The halogen-free low-smoke ultraviolet irradiation cross-linked polyolefin insulated wire gradually becomes the mainstream product to replace the traditional PVC wire because of its advantages of halogen-free flame retardant, low smoke and toxicity, excellent insulation performance and energy-saving current-carrying, and the optimization and upgrading of its processing technology and equipment have become the core direction of the industry

[0003] At present, the ultraviolet irradiation cross-linking technology has been widely used in the production of polyolefin insulated wire, and its core principle is to activate the cross-linking initiator in the insulation material by ultraviolet light to promote the formation of three-dimensional network structure of polyolefin molecules, thereby improving the comprehensive performance of the wire. However, the existing processing device and method still have many problems to be solved in practical application: first, the surface of the wire blank is easy to attach dust, oil stains and other impurities left over from the extrusion molding process before entering the irradiation link. These impurities not only affect the irradiation penetration efficiency of ultraviolet light, but also may form defects inside the insulation layer, resulting in a decrease in the insulation stability of the wire and increasing the safety hazards in the later use process; second, the traditional irradiation device usually uses ultraviolet lamp columns with fixed angles for irradiation, which is difficult to achieve uniform irradiation of the wire insulation layer in 360 degrees, and may cause insufficient cross-linking degree in local areas, resulting in large fluctuations in the performance indicators such as mechanical strength and heat deformation temperature of the wire; third, the irradiation device with rotation function usually drives multiple irradiation cylinders at the same speed, which cannot form a dynamic differential irradiation field, resulting in uneven distribution of irradiation energy and difficult to further optimize the cross-linking reaction effect, thereby restricting the improvement of the energy-saving current-carrying characteristics of the wire. SUMMARY

[0004] The purpose of the present application is to provide a processing device and method of halogen-free low-smoke ultraviolet irradiation cross-linked polyolefin insulated energy-saving wire to solve the problems raised in the background art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a processing device of halogen-free low-smoke ultraviolet irradiation cross-linked polyolefin insulated energy-saving wire, comprising a protective shell, an ultraviolet irradiation assembly is installed in the interior of the protective shell, a driving assembly is installed in the interior of the protective shell, a cleaning assembly is installed on one side of the protective shell, and a gas purification and exhaust device is installed on the top of the protective shell.

[0009] Preferably, the cleaning component includes an assembly block and a rotating ring. One side of the assembly block is connected to a cleaning cylinder, and a cleaning brush is installed inside the cleaning cylinder. Four snap-fit ​​pins are fixedly installed on the side of the assembly block away from the cleaning cylinder. A transmission gear ring four is fixedly installed on the outer side of the rotating ring. The rotating ring is rotatably mounted on one side of the protective shell. Four snap-fit ​​grooves are opened on one side of the rotating ring, and the four snap-fit ​​pins are snap-fitted into the four snap-fit ​​grooves. The transmission gear ring four is fixedly installed on the outer side of the rotating ring, and the outer side of the transmission gear ring four meshes with the outer side of the drive gear four. A protective cover is fixedly installed on one side of the protective shell, and the protective cover covers the outer side of the transmission gear ring four and the drive gear four.

[0010] Preferably, the gas purification and discharge device includes a processing box, which is fixedly installed on the top of the protective shell. The bottom of the processing box is connected to an air suction hood, which is located inside the protective shell. A connecting box is fixedly installed on one side of the processing box. Two air suction pipes are symmetrically connected to one side of the connecting box. The ends of the two air suction pipes away from the connecting box extend through the side wall of the processing box into the interior of the processing box. Air suction holes are opened on the side walls of the two air suction pipes.

[0012] Preferably, each of the three irradiation tubes (I, II, and III) has an exhaust port II on its outer side, and each of the transparent glass covers has an exhaust port I inside. Each of the exhaust ports I has a reflective arc plate fixedly installed on its outer side.

[0013] Preferably, the bottom of the protective shell is fixedly equipped with two support legs, which are symmetrically installed on both sides of the bottom of the protective shell.

[0014] A method for using a processing apparatus for halogen-free, low-smoke ultraviolet irradiation cross-linked polyolefin insulated energy-saving wires includes the following steps:

[0015] S1: The produced wire passes through the cleaning component on one side of the protective shell and the ultraviolet irradiation component inside the protective shell, and then extends out through the other end of the protective shell and is pulled by the external traction component. When the wire passes through the cleaning brush inside the cleaning cylinder, the cleaning brush can clean the dust and impurities on the outside of the cable.

[0016] S2: Then turn on the ultraviolet lamp columns inside irradiation cylinder one, irradiation cylinder two and irradiation cylinder three. The ultraviolet lamp columns emit ultraviolet rays, which can irradiate the wires passing through irradiation cylinder one, irradiation cylinder two and irradiation cylinder three through the light-transmitting glass cover. This activates the ultraviolet crosslinking initiator in the wire insulation material, which causes the polyolefin molecular chains to generate active free radicals. The free radicals drive the chemical bonding between molecules, which transforms the originally linearly arranged polyolefin molecules into a stable three-dimensional network structure. This improves the mechanical properties, heat distortion temperature and insulation stability of the wire insulation layer, while ensuring the energy-saving current-carrying characteristics of the wire.

[0017] S3: Then start the drive motor. The output of the drive motor can drive the three drive gears, the two drive gears and the one drive gear to rotate. This, in turn, drives the three transmission gear rings, the two transmission gear rings and the one transmission gear ring to rotate. This, in turn, drives the three irradiation tubes, the two irradiation tubes and the one irradiation tube to rotate. This, in turn, drives the internal ultraviolet lamp column to rotate, so as to achieve uniform irradiation of the insulation layer at 360 degrees.

[0018] S4: Then start the negative pressure pump. The negative pressure pump can extract the gas inside the treatment chamber through the connecting box and two suction pipes to create a negative pressure inside the treatment chamber. The harmful gases generated by the ultraviolet lamp columns inside irradiation tubes three, two, and one irradiation tube irradiating the wires will be discharged through exhaust port one and exhaust port two. The discharged gas will enter the interior of the treatment chamber through the suction hood, and then be filtered and adsorbed through the primary fiber filter layer, activated carbon adsorption layer, modified activated carbon layer, and fragrance cotton layer. Then the negative pressure pump will extract the treated gas through the suction pipe and connecting box, and then discharge it into the air through the exhaust pipe.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: by turning on the ultraviolet lamp columns inside the first, second, and third irradiation tubes, the ultraviolet lamp columns emit ultraviolet rays, which can irradiate the wires passing through the first, second, and third irradiation tubes through the light-transmitting glass cover, activating the ultraviolet light crosslinking initiator in the wire insulation material, causing the polyolefin molecular chains to generate active free radicals, driving the free radicals to initiate the chemical bonding between molecules, transforming the originally linearly arranged polyolefin molecules into a stable three-dimensional network structure, improving the mechanical properties, heat deformation temperature and insulation stability of the wire insulation layer, while ensuring the energy-saving current-carrying characteristics of the wire;

[0020] Furthermore, the output of the drive motor can drive the three drive gears, two drive gears, and one drive gear to rotate, which in turn drives the three transmission gear rings, two transmission gear rings, and one transmission gear ring to rotate, thereby driving the three irradiation tubes, two irradiation tubes, and one irradiation tube to rotate, which in turn drives the internal ultraviolet lamp columns to rotate, achieving 360-degree uniform irradiation of the insulation layer. Moreover, the different rotation speeds of the three irradiation tubes result in differential rotation of the ultraviolet lamp columns inside them, avoiding energy superposition or weak areas that may occur with fixed-angle irradiation. This not only improves the consistency of irradiation treatment but also further optimizes the cross-linking reaction effect through dynamic energy distribution, making the three-dimensional network structure more dense and uniform, thereby improving the irradiation effect.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7This invention provides a technical solution: a processing device for halogen-free, low-smoke ultraviolet irradiation cross-linked polyolefin insulated energy-saving wires, comprising a protective shell 1, an ultraviolet irradiation component installed inside the protective shell 1, and two guide cylinders 11, one end of each guide cylinder 11 being fixedly connected to the inside of the protective shell 1. An irradiation cylinder 12 is rotatably sleeved on the outer side of each guide cylinder 11 away from the protective shell 1, and an irradiation cylinder 13 is rotatably sleeved on the outer side of each irradiation cylinder 12 away from the guide cylinder 11. One end of 12 is rotatably mounted with an irradiation tube 14. Multiple ultraviolet lamp columns 35 are fixedly installed inside each of the irradiation tubes 12, 13, and 14. A light-transmitting glass cover 32 is fixedly installed inside each of the irradiation tubes 12, 13, and 14. Frame rings 29 are fitted onto the outer sides of the connection between irradiation tube 12 and 13, and between irradiation tube 23 and 14. Two fixing rods 30 are symmetrically fixedly installed on the outer side of the frame rings 29, with the end of the fixing rod 30 furthest from the frame ring 29... The protective shell 1 is internally fixedly connected, and a drive assembly is installed inside the protective shell 1. The drive assembly includes a drive motor 20, which is fixedly installed inside the protective shell 1. A rotating rod 17 is fixedly installed at the output end of the drive motor 20. A third drive gear 16, a fourth drive gear 26, two second drive gears 18, and two first drive gears 19 are fixedly installed on the outer side of the rotating rod 17. Transmission gear rings 25 are fixedly installed on the outer sides of both irradiation tubes 12, and the two first drive gears 19 mesh with the two transmission gear rings 25 respectively. Each irradiation tube 213 has a transmission gear ring 24 fixedly installed on its outer side, and two drive gears 218 mesh with the two transmission gear rings 24 respectively. The outer side of the irradiation tube 314 has a transmission gear ring 315 fixedly installed, and the outer side of the transmission gear ring 315 meshes with the outer side of the drive gear 316. A cleaning component is installed on one side of the protective shell 1, a gas purification and exhaust device is installed on the top of the protective shell 1, and a support leg 10 is fixedly installed on the bottom of the protective shell 1. There are two support legs 10, and the two support legs 10 are symmetrically installed on both sides of the bottom of the protective shell 1.

[0031] The working principle of the above technical solution is as follows: The produced wire is passed through the cleaning component on one side of the protective shell 1 and the ultraviolet irradiation component inside the protective shell 1. Then, the ultraviolet lamp columns 35 inside the irradiation tubes 12, 13, and 14 are turned on. The ultraviolet lamp columns 35 emit ultraviolet rays, which can pass through the light-transmitting glass cover 32 to irradiate the wire that has passed through the irradiation tubes 12, 13, and 14. This activates the ultraviolet crosslinking initiator in the wire insulation material, causing the polyolefin molecular chains to generate active free radicals. These free radicals drive the intermolecular chemical bonds to combine, transforming the originally linearly arranged polyolefin molecules into a stable three-dimensional network structure. This improves the mechanical properties, heat distortion temperature, and insulation stability of the wire insulation layer, while ensuring the energy-saving current-carrying characteristics of the wire. Then, the drive motor 20 is started, and the output end of the drive motor 20 can... The drive gears 16, 18, and 19 rotate, which in turn rotates the transmission gear rings 15, 24, and 25, thereby driving the irradiation tubes 14, 13, and 12 to rotate. This, in turn, drives the internal ultraviolet lamp columns 35 to rotate, achieving uniform irradiation of the insulation layer at 360 degrees. Furthermore, the different rotation speeds of the irradiation tubes 14, 13, and 12 result in differential rotation of the ultraviolet lamp columns 35 within them. This avoids energy superposition or weak areas that may occur with fixed-angle irradiation, improving the consistency of the irradiation process and further optimizing the cross-linking reaction through dynamic energy distribution. This makes the three-dimensional network structure more dense and uniform, thus enhancing the irradiation effect.

[0032] In another implementation scheme, such as Figures 1-7 As shown, the cleaning assembly includes an assembly block 6 and a rotating ring 36. A cleaning cylinder 7 is connected to one side of the assembly block 6. A cleaning brush 8 is installed inside the cleaning cylinder 7. Four snap-fit ​​pins 38 are fixedly installed on the side of the assembly block 6 away from the cleaning cylinder 7. A transmission gear ring 27 is fixedly installed on the outer side of the rotating ring 36. The rotating ring 36 is rotatably installed on one side of the protective shell 1. Four snap-fit ​​grooves 37 are opened on one side of the rotating ring 36, and the four snap-fit ​​pins 38 are snap-fitted into the four snap-fit ​​grooves 37. The transmission gear ring 27 is fixedly installed on the outer side of the rotating ring 36, and the outer side of the transmission gear ring 27 meshes with the outer side of the drive gear 26. A protective cover 9 is fixedly installed on one side of the protective shell 1, and the protective cover 9 covers the outer side of the transmission gear ring 27 and the drive gear 26.

[0033] When the wire passes through the cleaning brush 8 inside the cleaning cylinder 7, the cleaning brush 8 can clean the dust and impurities on the outside of the cable, preventing the dust and impurities from partially obstructing the wire and ensuring the irradiation effect of the ultraviolet lamp column 35 inside the subsequent irradiation cylinder 3 14, irradiation cylinder 2 13, and irradiation cylinder 1 12 on the wire. In addition, the four locking posts 38 and four locking slots 37 make it easy to disassemble the assembly block 6, thereby facilitating the replacement of the cleaning cylinder 7 and the cleaning brush 8 and ensuring the cleaning effect. Furthermore, after the drive motor 20 is started, it can drive the drive gear 4 26 to rotate through the rotating rod 17, thereby driving the transmission gear ring 4 27 to rotate, which in turn drives the rotating ring 36 and the assembly block 6 to rotate, and drives the cleaning cylinder 7 and the cleaning brush 8 to rotate. The rotating cleaning brush 8 can improve the cleaning effect on the outside of the wire.

[0034] In another implementation scheme, such as Figures 1-7 As shown, the gas purification and exhaust device includes a treatment box 2, which is fixedly installed on the top of the protective shell 1. A suction hood 28 is connected to the bottom of the treatment box 2 and is located inside the protective shell 1. A connecting box 3 is fixedly installed on one side of the treatment box 2. Two suction pipes 22 are symmetrically connected to one side of the connecting box 3. The ends of the two suction pipes 22 away from the connecting box 3 extend through the side wall of the treatment box 2 into the interior of the treatment box 2. Suction holes are provided on the side walls of both suction pipes 22. A negative pressure pump 4 is connected to the bottom of the connecting box 3. An exhaust pipe 5 is connected to the exhaust end of the negative pressure pump 4. A sealing plate 21 is sealed and snapped onto one side of the treatment box 2. A fragrance-enhancing cotton layer 23, a modified activated carbon layer 39, an activated carbon adsorption layer 40, and a primary fiber filter layer 41 are fixedly installed on one side of the sealing plate 21. The fragrance-enhancing cotton layer 23 is located outside the modified activated carbon layer 39, the modified activated carbon layer 39 is located outside the activated carbon adsorption layer 40, and the activated carbon adsorption layer 40 is located outside the primary fiber filter layer 41. A handle 42 is fixedly installed on one side of the sealing plate 21. An exhaust port 31 is opened on the outside of the first irradiation tube 12, the second irradiation tube 13, and the third irradiation tube 14. An exhaust port 33 is opened inside the light-transmitting glass cover 32. A reflective arc plate 34 is fixedly installed on the outside of the exhaust port 33.

[0035] The negative pressure pump 4 is started. The negative pressure pump 4 can extract the gas inside the treatment box 2 through the connecting box 3 and the two suction pipes 22 to create a negative pressure inside the treatment box 2. The harmful gases generated by the ultraviolet lamp columns 35 inside the irradiation tubes 14, 13, and 12 irradiating the wires will be discharged through the exhaust port 1 33 and the exhaust port 2 31. The discharged gas will enter the interior of the treatment box 2 through the suction hood 28, and then be filtered and adsorbed through the primary fiber filter layer 41, the activated carbon adsorption layer 40, the modified activated carbon layer 39, and the fragrance cotton layer 23. Then the negative pressure pump 4 extracts the treated gas through the suction pipe 22 and the connecting box 3, and then discharges it into the air through the exhaust pipe 5.

[0036] A method for using a processing apparatus for halogen-free, low-smoke ultraviolet irradiation cross-linked polyolefin insulated energy-saving wires includes the following steps:

[0037] S1: The produced wire passes through the cleaning component on one side of the protective shell 1 and the ultraviolet irradiation component inside the protective shell 1, and then extends out through the other end of the protective shell 1 and is pulled and moved by the external traction component. When the wire passes through the cleaning brush 8 inside the cleaning cylinder 7, the cleaning brush 8 can clean the dust and impurities on the outside of the cable.

[0038] S2: Then turn on the ultraviolet lamp columns 35 inside the irradiation tube 12, irradiation tube 23 and irradiation tube 34. The ultraviolet lamp columns 35 emit ultraviolet rays, which can pass through the light-transmitting glass cover 32 to irradiate the wires inside the irradiation tube 12, irradiation tube 23 and irradiation tube 34, activate the ultraviolet crosslinking initiator in the wire insulation material, promote the production of active free radicals in the polyolefin molecular chains, drive the free radicals to initiate the chemical bonding between molecules, and transform the originally linearly arranged polyolefin molecules into a stable three-dimensional network structure, improve the mechanical properties, heat deformation temperature and insulation stability of the wire insulation layer, and at the same time ensure the energy-saving current carrying characteristics of the wire.

[0039] S3: Then start the drive motor 20. The output end of the drive motor 20 can drive the drive gear 3 16, drive gear 2 18 and drive gear 1 19 to rotate, thereby driving the transmission gear ring 3 15, transmission gear ring 2 24 and transmission gear ring 1 25 to rotate, thereby driving the irradiation tube 3 14, irradiation tube 2 13 and irradiation tube 1 12 to rotate, thereby driving the internal ultraviolet lamp column 35 to rotate, so as to achieve uniform irradiation of the insulation layer at 360 degrees.

[0040] S4: Then start the negative pressure pump 4. The negative pressure pump 4 can extract the gas inside the treatment box 2 through the connecting box 3 and the two suction pipes 22 to form a negative pressure inside the treatment box 2. The harmful gases generated by the ultraviolet lamp columns 35 inside the irradiation tubes 14, 13, and 12 irradiation tubes 3 and 12 irradiating the wires will be discharged through the exhaust port 1 33 and exhaust port 2 31. The discharged gas will enter the interior of the treatment box 2 through the suction hood 28, and then be filtered and adsorbed through the primary fiber filter layer 41, activated carbon adsorption layer 40, modified activated carbon layer 39 and fragrance cotton layer 23. Then the negative pressure pump 4 extracts the treated gas through the suction pipe 22 and the connecting box 3, and then discharges it into the air through the exhaust pipe 5.
