Description

Technical Field

[0001] The present invention relates to the technical field of silk-covered wire processing, and specifically to a silk-covered wire cable production line and its process. Background Art

[0002] Silk-covered wire processing is a manufacturing process in which a metal conductor (such as a copper wire or an aluminum wire) is wrapped with multiple layers of insulating materials and painted to form an electromagnetic wire with a high-strength insulating layer and good mechanical properties. Silk-covered wires are mainly used in windings in electrical equipment, such as motors, transformers, electromagnetic coils, etc., to meet the requirements of high voltage, high current, and high mechanical strength.

[0003] The current silk-covered wire process is as follows:

[0004] Step 1: Wire feeding. The wire is released from the coil and automatically fed by a wire feeder at a speed of 5 - 8 meters per minute.

[0005] Step 2: Straightening. The bent wire is straightened by a straightening machine to facilitate subsequent operations.

[0006] Step 3: Painting. The first coat of paint is applied to the wire, keeping the horizontal height of the wire the same as in the straightening step.

[0007] Step 4: Wrapping. During the first painting process, it needs to be air-dried for a certain period of time, that is, the wire is exposed to the air to make the paint have a certain viscosity, and then the insulating material is wrapped around the wire, with the wire height the same as in the above steps.

[0008] Step 5: Painting. The second coat of paint is applied again on the insulating material.

[0009] Step 6: Baking. The second painting process is dried by a heat treatment device to cure the paint. The power of the heat treatment device is 20 kW, and the internal temperature of the device is maintained between 100°C and 325°C. The wire is coiled around the guide wheel seven to eight times for multiple baking processes. The entire baking process at a single point takes 40 minutes. During the second or third winding of the wire, an additional coat of paint is applied for the third painting process.

[0010] Step 7: Wire winding. The processed wire is wound together by a coil winding device at a speed of 5 - 8 meters per minute to complete the processing.

[0011] Its production process is complex, requiring multiple painting processes and multiple baking processes. Moreover, its baking time is long, affecting its processing time and greatly reducing its processing efficiency.

[0012] Since the movement of the wire is pulled by the wire-taking equipment and the rollers are used to keep the overall speed of the cable consistent, the wrapping process can adjust its speed to adapt to the pulling rate of the cable. In the painting process, due to the different types of paint, the time required for immersion is different, and the time required for multiple paint coatings is also different. Therefore, the pulling rate of the cable cannot be adjusted to adapt to the immersion time of the paint. The paint immersion time can only be controlled by changing the length of the paint. Therefore, the equipment lengths for the first, second and third coats of paint are different, including the subsequent heat treatment drying time. Different drying times will be used according to the temperature and the number of layers of paint. Therefore, the pulling rate of the cable cannot be adjusted to adapt to the time required for different processes.

[0013] The painting process of the cable in the above process is relatively cumbersome and requires multiple steps. Different insulating materials absorb paint at different speeds. Therefore, the above painting process is a fixed time and cannot be changed according to the material. Only painting equipment of different lengths can be replaced, which greatly increases the production cost. In addition, the addition of paint in the whole process requires manual processing, which greatly increases the workload of the staff. After the paint is applied, it drips directly onto the outside and cannot be recovered, resulting in waste. Summary of the invention

[0014] In order to solve the above problems existing in the prior art, the present invention provides a silk-covered wire cable production line and a process thereof, which has the advantages of adjusting the painting time and automatically adding paint to recycle the paint.

[0019] Preferably, the filter baffle is located on one end face of the adjusting plate. The filter baffle is provided with at least two filter grooves, and a number of filter holes are opened in the filter grooves. A water discharge port is further opened at the bottom of the dipping tank, and the water discharge port is the same size as the filter groove.

[0020] Preferably, the auxiliary gear is located at the edge of the adjusting plate. A through cable hole is further opened in the middle of the adjusting plate, and the cable passes through the cable hole. The diameter of the cable hole is larger than the diameter of the cable.

[0021] Preferably, the traveling assembly includes a partition plate fixed in the dipping tank and a long gear rotating in the dipping tank. An auxiliary motor is installed on one side of the long gear. Two symmetrical lead screws are rotatably connected to the partition plate. The lead screws penetrate through the adjusting plate and extend to the inner wall of the dipping tank. The lead screws are in threaded cooperation with the adjusting plate, and the other ends of the lead screws are connected with a synchronous motor, and the lead screws are driven by the synchronous motor.

[0022] Preferably, a support column is fixed at the bottom inside the dipping tank, and a paint filtering block is installed on the support column. The support column is located between the adjusting plate and the partition plate, and the cable passes through the paint filtering block.

[0023] Preferably, the conduit is divided into two ends connected to the dipping tank. One end is located between the support column and the adjusting plate, and a second one-way valve is provided at the connection here. A first one-way valve is provided at the other connection. A water suction pipe is installed on the paint pump, and the water suction pipe extends to the bottom of the paint storage tank. The first one-way valve allows the liquid to flow from the conduit into the dipping tank and communicate with it, and the second one-way valve allows the liquid to flow from the dipping tank into the conduit and communicate with it.

[0024] Preferably, the light curing device includes a curing box body, a condenser tube and a power supply bin. The condenser tube and the power supply bin are both installed in the curing box body. A light source mounting block is further fixed on the curing box body, and a heat dissipation port is opened at the light source mounting block. The power supply bin is installed in the light source mounting block, and a light source is installed on the power supply bin. An adjusting reflector, a lower reflector and an upper reflector are arranged in the condenser tube. The adjusting reflector is located below the power supply bin, the lower reflector is located on the side of the adjusting reflector, and the upper reflector is located above the adjusting reflector and close to the power supply bin. The opposite end faces of the lower reflector and the upper reflector are both arc-shaped.

[0025] Preferably, a contact cylinder is further fixed to the top of the dipping tank. A trigger rod is slidably arranged in the contact cylinder. A hollow floating block is arranged at the bottom of the trigger rod. Contact switches are arranged at the top and bottom inside the contact cylinder. A tank cover is hinged to the top of the dipping tank. Support wheels are fixed to both sides of the dipping tank. A plurality of [objects] are fixed to the bottom of the dipping tank. The paint storage cylinder is located between two opposite sides.

[0026] The production process of a silk-covered wire cable production line is as follows:

[0027] S1: Wire release. The wire is released from the coil and automatically released by a wire release machine. The wire speed is controlled at 10 - 15 meters per minute.

[0028] S2: Straightening. The wire released during the wire release process is straightened by a straightening machine to facilitate subsequent operations. The position of the wire is at the same horizontal position as the wire release process, that is, the height is the same, and the wire speed remains unchanged.

[0029] S3: Wrapping. The straightened wire is horizontally inserted into a double-layer wrapping device. When double-layer wrapping, the wrapping directions of the inner and outer layers are opposite. The wrapping speed is 10 - 20 meters per minute. The wrapping material is an insulating material (such as glass fiber). The wire is directly wrapped. The thickness of the insulating material wrapping is 0.02 mm - 0.4 mm, and the number of wrapping layers is 1 - 2 layers.

[0030] S4: Dipping. The wrapped wire enters the paint cylinder. The temperature of the paint cylinder is maintained at 25°C - 40°C to ensure that the paint is in a viscous state. The wire directly passes through the paint cylinder. The wire speed remains unchanged, the same as the wire release speed above, and the height is the same as the wrapping height. The paint directly penetrates into the insulating material and is coated on the surface of the insulating material. The thickness of the paint coating is 0.04 mm - 0.1 mm. The painting process can be completed by one dipping. The wire is exposed after the paint drops two centimeters.

[0031] S5: Curing. After the wire dipping is completed, it enters the light curing equipment while keeping its height unchanged. Light source direct irradiation is used for curing. One of ultraviolet (UV) or visible light is used as the light source. The wavelength of the UV light is 320 - 400 nanometers, and the wavelength of the visible light is 400 - 500 nanometers. The light intensity range is 100 - 500 mW / cm². The temperature inside the curing equipment is maintained at 20°C - 40°C. The light irradiation causes a chemical reaction (free radical polymerization) in the paint, making it cure rapidly. The light exposure time is 10 - 60 seconds.

[0032] S6: Wire winding. The cured wire is wound together by a coil wire winding equipment. The position of the wire winding is at the same height as the wire release position, and the wire speed is also controlled at 10 - 15 meters per minute to complete the processing.

[0033] Compared with the prior art, the present invention provides a silk-covered wire cable production line and process thereof, which has the following beneficial effects:

[0034] 1. The silk-covered cable paint coating equipment can drive the lead screw to rotate through a synchronous motor, and can drive the adjustment plate to move in parallel through a threaded arrangement, so as to change the size of the chamber formed between the adjustment plate and the paint immersion tank. If other conditions remain unchanged, the smaller the chamber, the shorter the overall immersion length of the cable. Therefore, the immersion length of the cable can be controlled according to the material of the different silk-covered wires, so as to control the time and degree of immersion. In conjunction with the subsequent light-curing process, the paint can be directly cured without the need for multiple painting procedures, which greatly shortens the production length and process of the silk-covered wire. In addition, no bending is required during the entire process, which reduces the damage to the cable stress caused by bending.

[0035] 2. The silk-covered cable paint coating equipment can discharge the paint by arranging the filter groove and the drain port so that the filter groove and the drain port overlap each other. The paint is filtered through the filter holes on the filter groove, which can prevent the dirt generated when the cable is dipped in paint from entering the paint storage tank and causing the paint pump to be blocked. In addition, each time the equipment is started and shut down, the next filter groove will be used for filtering, without the need to frequently replace the filter net, and the filter holes on the filter groove can be effectively prevented from being blocked.

[0036] 3. The silk-covered cable paint coating equipment can trigger the paint pump to start and add paint again when the paint level leaks below the cable hole. During the addition of new paint, it will impact the paint immersion tank, which is equivalent to stirring it to make the paint flow, which can effectively avoid the precipitation of paint and make the concentration of the upper and lower layers of the paint differ greatly, affecting the silk thread's absorption of paint. Leakage will accelerate the consumption of paint in the paint immersion tank. Increasing the frequency of adding paint by the paint pump can make the concentration of the paint in the paint immersion tank more uniform.

[0037] 4. The silk-covered wire paint photocuring equipment, through the setting of new process, does not need painting operation before its winding process, which shortens the whole process and saves the production time of silk-covered wire. Moreover, it only needs one painting operation, and in conjunction with its photocuring process, it effectively avoids multiple painting operations, and the overall energy consumption of the photocuring process is greatly reduced. At the same time, since the drying procedure of paint curing is reduced and the photocuring process as a whole only takes a short time to complete the curing, it also greatly improves the overall production efficiency. Moreover, the wire does not need to be bent in the whole process, and the overall horizontal movement shortens the processing length of the wire on the one hand, and avoids the phenomenon of softening of the cable and affecting its bending stress due to multiple bending on the other hand.

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0050] As Figure 1-8As shown, the dipping equipment includes a dipping tank 10 into which paint can be injected. The paint can be water-based paint. A tank cover 11 is installed on the dipping tank 10. A paint device is provided at the bottom of the dipping tank 10. An adjusting device is also installed in the dipping tank 10. The top of the dipping tank 10 is hinged with a tank cover 11. Support wheels 101 are fixed on both sides of the dipping tank 10 to support the cable so that it can enter the dipping tank 10 horizontally. A number of 12 are fixed at the bottom of the dipping tank 10. A paint storage cylinder 22 is arranged between two opposite 12. A number of buttons are provided on the front end face of the dipping tank 10 to control the entire equipment. The adjusting device includes an adjusting plate 30 and a traveling component. The adjusting plate 30 slides inside the dipping tank 10. The adjusting plate 30 is located between the connections of the two side conduits 20.

[0051] A secondary pulley 304 is rotatably connected inside the adjusting plate 30. The secondary pulley 304 can rotate freely inside the adjusting plate 30 but cannot slide. A filter baffle 301 is detachably installed on the secondary pulley 304. Their installation method can be threaded connection or snap connection. An auxiliary gear 302 and a main pulley 305 are also rotatably connected inside the adjusting plate 30. The auxiliary gear 302 and the main pulley 305 are connected together by a rotating shaft. The main pulley 305 is connected to the secondary pulley 304 by a belt 306. A part of the auxiliary gear 302 is exposed outside the adjusting plate 30 and can be used to engage with other components. The filter baffle 301 is located on one side end face of the adjusting plate 30. At least two filter grooves 3011 are provided on the filter baffle 301, preferably two. A number of filter holes are provided in the filter grooves 3011. A drain port 307 is also provided at the bottom of the dipping tank 10. The drain port 307 is the same size as the filter groove 3011. Each installation of the filter baffle 301 will be in a fixed position, that is, one of the filter grooves 3011 is in the same position as the drain port 307. Through the settings of the filter groove 3011 and the drain port 307, when draining the paint, the filter groove 3011 and the drain port 307 can be made to coincide for drainage. The paint is filtered through the filter holes on the filter groove 3011, which can prevent the dirt generated when the cable is dipped in the paint from entering the paint storage cylinder 22 and causing the paint pump 21 to be blocked. Moreover, each time the equipment is started and stopped, the next filter groove 3011 will be used for filtration, eliminating the need for frequent replacement of the filter screen and effectively preventing the filter holes on the filter groove 3011 from being blocked.

[0052] The auxiliary gear 302 is located at the edge of the adjustment plate 30. A cable hole 303 is also provided in the middle of the adjustment plate 30. The cable passes through the cable hole 303. The diameter of the cable hole 303 is larger than the diameter of the cable. The diameter of the cable hole 303 is slightly larger than the diameter of the cable. After the cable is dipped in paint, the paint on the cable will not be directly scraped off to avoid affecting the silk thread to absorb the paint. At the same time, the paint in the paint dipping tank 10 will be brought out when the line is out, causing partial leakage. When the paint liquid level leaks below the hole of the cable hole 303, the paint pump 21 can be triggered to start and add paint again. In the process of adding new paint, the paint dipping tank 10 will be affected. Impacting the paint in the tank 10 is equivalent to stirring it, which can effectively avoid the precipitation of the paint and make the concentration of the upper and lower layers of the paint differ greatly, affecting the absorption of the paint by the silk thread. Leakage will accelerate the consumption of the paint in the paint dipping tank 10. Increasing the frequency of adding paint by the paint pump 21 can make the concentration of the paint in the paint dipping tank 10 more uniform. The leaked paint will flow into the conduit 20 through the second one-way valve 202, and there is no check valve in the paint pump 21, so it can also flow into the paint storage tank 22 through the paint pump 21 to form a cycle, and the paint volume in the paint storage tank 22 is much larger than the volume in the paint dipping tank 10.

[0053] The traveling assembly includes an isolation plate 40 fixed in the paint dipping tank 10 and a long gear 71 rotating in the paint dipping tank 10. An auxiliary motor 70 is installed on one side of the long gear 71. The auxiliary motor 70 controls the rotation of the long gear 71. The long gear 71 is meshed with the auxiliary gear 302. The auxiliary gear 302 can slide on the long gear 71. Two symmetrical lead screws 402 are rotatably connected to the isolation plate 40. The lead screws 402 penetrate the adjustment plate 30 and extend to the inner wall of the paint dipping tank 10. The lead screws 402 and the adjustment plate 30 are threadedly matched. The other end of the lead screw 402 is connected to a synchronous motor 401, which is used to drive the lead screw 402, and the synchronous motor 401 is fixed. It is fixed on an inner end face of the paint dipping tank 10, and the lead screw 402 can be driven to rotate by the synchronous motor 401. Through the threaded matching arrangement, the adjusting plate 30 can be driven to move in parallel, so as to change the size of the chamber formed between the adjusting plate 30 and the paint dipping tank 10. While other conditions remain unchanged, the smaller the chamber, the shorter the overall dipping length of the cable. Therefore, the dipping length of the cable can be controlled according to the material of the different silk-covered wires, so as to control the time and degree of dipping. In conjunction with the subsequent light-curing process, the paint can be directly cured without the need for multiple painting procedures, which greatly shortens the production length of the silk-covered wire. In addition, no bending is required during the entire process, thereby reducing the damage to the cable stress caused by bending.

[0054] like Figure 7As shown in the figure, a brush plate groove 80 is further formed inside the adjusting plate 30. A brush plate 81 is detachably arranged in the brush plate groove 80 and fixedly arranged in the brush plate groove 80. The brush plate groove 80 is located on the side of the adjusting plate 30 close to the filter baffle 301. The length of the brush plate 81 is the same as that of the filter groove 3011. When the filter baffle 301 rotates, the filter groove 3011 can be driven to rotate onto the brush plate 81, and the bristles on the brush plate 81 can immediately brush off the impurities on the filter holes, thereby prolonging the service life of the filter baffle 301, further reducing the replacement frequency of the filter baffle 301, and enabling it to be used for a longer time.

[0055] A support column 50 is fixed to the bottom inside the dip painting tank 10. A paint filtering block 51 is installed on the support column 50. The support column 50 is located between the adjusting plate 30 and the isolation plate 40. The cable passes through the paint filtering block 51, and a paint spreading assembly is arranged in the paint filtering block 51 to evenly spread the paint and avoid uneven distribution of the paint on the cable due to gravity.

[0056] The paint device includes a conduit 20 and a paint storage cylinder 22. The conduit 20 is installed at the bottom of the dip painting tank 10 and is internally connected. The conduit 20 is connected to the paint storage cylinder 22 through a paint pump 21. The conduit 20 is divided into two ends and connected to the dip painting tank 10. One end is located between the support column 50 and the adjusting plate 30, and a second one-way valve 202 is arranged at the connection here. A first one-way valve 201 is arranged at the other connection. A water suction pipe 211 is installed on the paint pump 21, and the water suction pipe 211 extends to the bottom of the paint storage cylinder 22. The first one-way valve 201 and the second one-way valve 202 can only allow liquid to flow unidirectionally. The first one-way valve 201 allows liquid to only flow from the conduit 20 into the dip painting tank 10 and be connected to it, and the second one-way valve 202 allows liquid to only flow from the dip painting tank 10 into the conduit 20 and be connected to it. Both cannot flow in the reverse direction.

[0057] A contact cylinder 60 is further fixed to the top of the dip painting tank 10. A trigger rod 61 is slidably arranged in the contact cylinder 60. A hollow floating block 611 is arranged at the bottom of the trigger rod 61. Contact switches are arranged at the top and bottom inside the contact cylinder 60. After injecting paint into the dip painting tank 10, the floating block 611 will generate buoyancy. However, when the paint reaches a certain liquid level, the top of the trigger rod 61 touches the contact switch at the top inside the contact cylinder 60, and the paint pump 21 can be turned off to stop injecting paint into the dip painting tank 10. However, when the paint is used and leaks to a certain extent where its liquid level drops, the floating block 611 will drive the trigger rod 61 to move to contact the contact switch at the bottom of the contact cylinder 60 under its gravity, and the paint pump 21 can be started to continue injecting paint into the dip painting tank 10, thereby achieving the effect of automatically adding paint.

[0058] Working principle: When in use, the wrapped cable is threaded into the dipping tank 10 through the support wheel 101, passes through the adjusting plate 30, the paint filtering block 51 and the isolation plate 40, and then exits the dipping tank 10. When starting or shutting down the entire device, the auxiliary motor 70 is also started, driving the long gear 71 to rotate, which can drive the auxiliary gear 302 to rotate. The rotation of the auxiliary gear 302 drives the driven pulley 304 to rotate through the main pulley 305 and the belt 306, thereby driving the filter baffle 301 to rotate. Each time the auxiliary motor 70 starts, it rotates 90 degrees and then stops rotating. Therefore, when the device was shut down last time, the filter groove 3011 was facing the drain port 307, and when the device is started this time, the blank part of the filter baffle 301 is facing the drain port 307, which can block the drain port 307. At this time, the synchronous motor 401 can be started by the button outside the dipping tank 10, and the adjusting plate 30 is driven to translate by the lead screw 402 to make it reach the appropriate length. When the device starts, since there is no liquid in the dipping tank 10, the trigger rod 61 is always in contact with the contact switch in the contact cylinder 60. Therefore, the paint pump 21 is also started at this time, and the paint in the paint storage cylinder 22 can be injected into the dipping tank 10 through the conduit 20 from the first one-way valve 201 until the liquid level in the dipping tank 10 rises to drive the trigger rod 61 to contact the contact switch at the top of the contact cylinder 60. At this time, the paint pump 21 can be shut down, and the production line starts to drive the cable to move in the dipping tank 10 to complete the paint coating.

[0059] During the movement of the cable, there will be a certain amount of leakage at the position where it contacts the adjusting plate 30, and the paint filtering block 51 will also scrape off the excess paint on the cable. These paints will fall and flow towards the second one-way valve 202, and flow into the conduit 20 through the second one-way valve 202 for reuse to avoid waste.

[0060] After the cable runs for a long time, due to the dual consumption of leakage and use of the paint, its liquid level will drop to a certain extent. At this time, the floating block 611 drives the trigger rod 61 to contact the bottom contact switch of the contact cylinder 60, which can start the paint pump 21 to pump the paint in the paint storage cylinder 22 into the dipping tank 10 again until the liquid level in the dipping tank 10 rises to drive the trigger rod 61 to contact the contact switch at the top of the contact cylinder 60, and the paint pump 21 will be shut down again to achieve the purpose of automatically replenishing the paint.

[0061] When the entire device is shut down, the auxiliary motor 70 has an independent power supply. The auxiliary motor 70 can be started to drive the filter baffle 301 to rotate 90 degrees, so that the filter groove 3011 faces the drain port 307. Then the paint in the dipping tank 10 will flow out, pass through the second one-way valve 202, the conduit 20 and the paint pump 21, and reflow into the paint storage cylinder 22, effectively avoiding paint volatilization and deterioration, and will be pumped out again when the device is started next time.

[0062] In summary, the silk-covered cable paint dipping equipment can drive the lead screw 402 to rotate through the synchronous motor 401, and can drive the adjustment plate 30 to move in parallel through the threaded matching setting, so as to change the size of the chamber formed between the adjustment plate 30 and the paint dipping tank 10. When other conditions remain unchanged, the smaller the chamber, the shorter the overall dipping length of the cable. Therefore, the dipping length of the cable can be controlled according to the material of different silk-covered wires to control the time and degree of dipping. In conjunction with the subsequent light-curing process, the paint can be directly cured without the need for multiple painting procedures, which greatly shortens the production length of the silk-covered wire. Moreover, the entire process does not require bending, which reduces the damage to the cable stress caused by bending. By setting the filtering groove 3011 and the drain port 307, when discharging the paint, the filtering groove 3011 can be made to overlap with the drain port 307 for discharge, and the paint can be discharged through the filtering groove 3 The filter holes on 011 filter the paint, which can prevent the dirt generated by the cable when it is dipped in paint from entering the paint storage tank 22 and causing the paint pump 21 to be blocked. In addition, each time the device is started and shut down, the next filter groove 3011 will be used for filtering, and there is no need to frequently replace the filter screen, which can also effectively prevent the filter holes on the filter groove 3011 from being blocked. When the paint level leaks below the hole of the cable hole 303, the paint pump 21 can be triggered to start and re-add paint. In the process of adding new paint, the paint dipping tank 10 will be impacted, which is equivalent to stirring it, which can effectively prevent the paint from precipitating and make the concentration of the upper and lower layers of the paint differ greatly, affecting the absorption of the paint by the silk thread. Leakage will accelerate the consumption of paint in the paint dipping tank 10. Increasing the frequency of adding paint by the paint pump 21 can make the concentration of the paint in the paint dipping tank 10 more uniform. Example 2

[0063] like Figure 9 and Figure 10 As shown, the light curing equipment includes a curing box 90, a focusing tube 91 and a power supply compartment 92, wherein the focusing tube 91 and the power supply compartment 92 are both installed in the curing box 90, a light source mounting block 901 is also fixed on the curing box 90, a heat dissipation port 902 is provided at the light source mounting block 901, the power supply compartment 92 is installed in the light source mounting block 901, a light source is installed on the power supply compartment 92, an adjustment reflector 911, a lower reflector 912 and an upper reflector 913 are arranged in the focusing tube 91, the adjustment reflector 911 is located at the lower side of the power supply compartment 92, the lower reflector 912 is located at the side of the adjustment reflector 911, the upper reflector 913 is located at the upper side of the adjustment reflector 911 and close to the power supply compartment 92, and the relative end faces of the lower reflector 912 and the upper reflector 913 are both arc-shaped.

[0064] By adjusting the settings of the reflector 911, the upper reflector 913 and the lower reflector 912, the light can be reflected at least three times. When the light shines directly on the cable, it can irradiate the upper part of the cable. The light reflected by adjusting the reflector 911 can irradiate the lower part of the cable. The light reflected by the upper reflector 913 will irradiate the upper part of the cable again. The light reflected by the lower reflector 912 will irradiate the lower part of the cable again, completing the segmented full irradiation of the cable paint. The reflection setting can increase the utilization rate of light, greatly reducing the energy consumption of the light source. The segmented irradiation generated by reflection can divide the curing process into multiple stages. In the free radical photopolymerization process, oxygen will inhibit the curing reaction (oxygen inhibition). Oxygen will react with the active free radicals generated by photoinitiation to form stable peroxy free radicals, thus terminating the polymerization reaction of free radicals. The long-term continuous irradiation at the same place will continuously consume oxygen for reaction, resulting in an oxygen inhibition state both inside and outside the cable, unable to effectively complete the curing, thus causing insufficient curing reaction and unable to meet the curing requirements. Segmented curing can quickly consume the oxygen on the surface of the paint through the first irradiation to produce a reaction, and then the reaction can end through the unirradiated part, forming a protective film to isolate oxygen. When it is irradiated again, the oxygen content in the paint inside the cable paint will be greatly reduced, and its curing reaction effect is better and the curing effect is more sufficient. Example 3

[0065] A production process of a silk-covered wire cable production line, and its production steps are as follows:

[0066] S1: Pay-off. The wire is released from the coil, and the wire is automatically payed off by a pay-off machine. The wire speed is controlled at 10 - 15 meters per minute;

[0067] S2: Straightening. The wire released during the pay-off process is straightened by a straightening machine to facilitate subsequent operations. The position of the wire is at the same horizontal position as the pay-off process, that is, the height is the same, and the wire speed remains unchanged;

[0068] S3: Wrapping. The straightened wire is horizontally inserted into a double-layer wrapping device. When wrapping in double layers, the winding directions of the inner and outer layers are opposite. The wrapping speed is 10 - 20 meters per minute. The wrapping material is an insulating material (such as glass fiber), and the wire is directly coated. The thickness of the insulating material coating is 0.02 mm - 0.4 mm, and the number of wrapping layers is 1 - 2 layers;

[0069] S4: Impregnation. The wrapped wire enters the paint tank. The paint tank maintains a temperature of 25°C - 40°C to ensure that the paint is in a viscous state. The wire directly passes through the paint tank, and the wire speed remains unchanged, which is the same as the above pay-off speed, and the height is the same as the wrapping height. The paint directly penetrates into the insulating material and is coated on the surface of the insulating material. The thickness of the paint coating is 0.04 mm - 0.1 mm, and the painting process can be completed by one impregnation. The wire is exposed after the paint drops two centimeters;

[0070] S5: Curing. After the wire is dipped, keep its height unchanged and enter the light curing equipment. Use direct light source for curing. Use ultraviolet light (UV) or visible light as the light source. The UV light wavelength is 320-400 nanometers, the visible light wavelength is 400-500 nanometers, and the light intensity range is 100-500 mW / cm². The internal temperature of the curing equipment is maintained at 20℃-40℃. The light irradiates the paint to produce a chemical reaction (free radicals produce polymerization), which makes it cure quickly. The light exposure time is 10-60 seconds.

[0071] S6: Wire taking-up: The solidified wire is wound together with the processed wire through the coil wire taking-up equipment. The wire taking-up position is highly consistent with the wire paying-out position, and the wire speed is also controlled at 10-15 m / min to complete the processing.

[0072] In the above process, no painting operation is required before the wrapping process, which shortens the entire process and saves the production time of the silk covered wire. Moreover, only one painting operation is required. In conjunction with the light curing process, multiple painting operations are effectively avoided, and the overall energy consumption of the light curing process is greatly reduced. At the same time, since the drying procedure of paint curing is reduced and the light curing process as a whole only takes a short time to complete the curing, the overall production efficiency is greatly improved.

[0073] In the above process, the wire does not need to be bent and moves horizontally as a whole, which shortens the processing length of the wire and avoids the phenomenon that multiple bending causes the cable to become soft and affects its bending stress.
