Description

Technical Field

[0001] This invention relates to the field of wire production technology, specifically to a wire coating light curing device. Background Technology

[0002] Silk-covered wire is a type of electromagnetic wire in which natural silk or fiber filaments (such as nylon, polyester fiber, natural silk, self-adhesive filaments, etc.) are wrapped around the conductor as an insulation layer.

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

[0004] Step 1: Wire release. The wire is released from the coil automatically by the wire release machine.

[0005] Step 2: Straighten the wire by using a straightening machine to make subsequent operations easier;

[0006] Step 3: Applying paint, applying the first coat of paint to the wires;

[0007] Step 4: Wrapping. During the first coat of paint, the wires need to be allowed to air dry for a certain period of time, which means exposing the wires to the air so that the paint has a certain stickiness. Then, wrap the insulating material around the wires.

[0008] Step 5: Apply a second coat of paint to the insulating material;

[0009] Step Six: Baking. The second coating process is dried using heat treatment equipment to cure the paint. The wire is wound around the guide wheel seven to eight times and undergoes multiple drying processes. The wire is coated with an additional layer of paint during the second or third winding process, and then undergoes a third coating process.

[0010] Step 7: Winding up the wires. The processed wires are wound together using a coil winding device to complete the processing.

[0011] Its production process is complex, requiring multiple painting processes and multiple drying processes. Moreover, its drying time is long, which affects its processing time and greatly reduces its processing efficiency.

[0012] In the above processing, the drying process of the paint is carried out by heating wire, which consumes a lot of energy. Moreover, the drying process requires eight turns and eight drying steps to meet the production requirements of the silk-covered wire. In addition, the wire needs to be bent during the winding process. The multiple bending of the wire during the production process will damage its pressure resistance and bending stress, resulting in a reduction in the quality of the wire after production. Summary of the Invention

[0013] To address the aforementioned problems in the prior art, this invention provides a UV curing device for silk-covered wire paint, which has the advantage of enabling rapid curing of paint.

[0014] To achieve the above-mentioned goal of rapidly curing paint, the present invention provides the following technical solution: including an equipment housing, a focusing tube fixed inside the equipment housing, a light source mounting block fixed on the upper surface of the equipment housing, and a light source assembly and a reflector assembly disposed inside the equipment housing;

[0015] The light source assembly is disposed within the light source mounting block, and its light-emitting part is obliquely positioned to emit a beam of light at an angle. Furthermore, a light-shielding group is also disposed within the light source assembly.

[0016] The light-shielding assembly includes an extension plate, and at least two light-shielding plates are slidably disposed inside the extension plate. The two opposing light-shielding plates attract each other to achieve a light-shielding effect.

[0017] The reflective components are all disposed inside the focusing tube, and include an adjustable reflector, an upper reflector, and a lower reflector. The adjustable reflector rotates inside the focusing tube at an angle of 10°-30°. The upper and lower reflectors slide inside the focusing tube, and the opposite end faces of the upper and lower reflectors are both arc-shaped.

[0018] The focusing tube is divided into two parts, each with a cross-section of two semicircles. The two parts are combined to form a hollow cylindrical structure. Slide rails are provided at the connection points of the two ends of the focusing tube. The upper reflector and the lower reflector are located within the slide rails.

[0019] The upper reflector is located on the upper slide rail, and the lower reflector is located on the lower slide rail. The opposite end faces of the upper and lower reflectors are both arc-shaped.

[0020] By adjusting the settings of the reflector, upper reflector, and lower reflector, the light can be reflected at least three times. When the light shines directly on the cable, it can illuminate the upper part of the cable. By adjusting the settings of the reflector, the light reflected by the upper reflector will illuminate the upper part of the cable again, and the light reflected by the lower reflector will illuminate the lower part of the cable again, thus completing the segmented and comprehensive illumination of the cable paint.

[0021] An adjustment block is fixed to the front side of the equipment housing. An adjustment shaft is rotatably connected inside the focusing tube. The adjustment shaft passes through the equipment housing and into the adjustment block. One end of the adjustment shaft is connected to the adjustment reflector, and the other end is fixed with a worm gear. A worm is also rotatably connected inside the adjustment block. The worm passes through the adjustment block to the outside. An adjustment knob is fixed to the outside part of the worm. The worm and the worm gear cooperate with each other.

[0022] Preferably, the light source assembly includes a power supply compartment installed inside the light source mounting block, a light source emitting block is provided at the bottom of the power supply compartment, the bottom of the light source emitting block is inclined, a light source inner groove is provided on its bottom end face, a plurality of light sources are provided at the bottom of the light source inner groove, and the light source emitting block is located inside the focusing tube.

[0023] Preferably, the light-shielding group is located on both sides of the light source emitting block, and includes an extension plate. The extension plate has a light-shielding plate groove inside, and several electromagnets are provided on both end faces of the extension plate. The electromagnets are electrically connected to an external switch through wires.

[0024] Preferably, at least two light-shielding plates are slidably disposed inside the light-shielding plate groove. The number of light-shielding plates is even and they are symmetrically arranged. A limit rod is also fixed inside the light-shielding plate groove. The limit rod passes through all the light-shielding plates. The light-shielding plates slide on the limit rod. The light-shielding plates and the limit rod are connected together by a spring.

[0025] Preferably, the focusing tube also has a sliding groove, in which a sliding rod and a brush block are slidably disposed. The brush block is fixed on the sliding rod, which has a handle. The bottom of the brush block has bristles.

[0026] Preferably, heat dissipation vents are provided on both sides of the light source mounting block, and a cooling fan is provided inside the heat dissipation vents.

[0027] Preferably, support wheels are also installed on both sides of the equipment housing, with the cable located on the support wheels and at the center of the focusing tube.

[0028] Compared with the prior art, the present invention provides a UV curing device for silk-covered wire paint, which has the following beneficial effects:

[0029] 1. This wire coating UV curing equipment, by adjusting the settings of the reflectors, upper reflector, and lower reflector, allows light to be reflected at least three times. When the light shines directly on the cable, it can illuminate the upper part of the cable. By adjusting the settings of the reflectors, the light reflected can illuminate the lower part of the cable. The light reflected by the upper reflector will illuminate the upper part of the cable again, and the light reflected by the lower reflector will illuminate the lower part of the cable again, thus completing the segmented and comprehensive illumination of the cable coating. The reflection settings can increase the utilization rate of light and greatly reduce the energy consumption of the light source.

[0030] 2. This wire coating UV curing equipment uses mirror-like curved surfaces on both the upper and lower reflectors to reflect light. The curved surfaces create a focusing effect on direct light, converging it along the center line of the upper reflector's length. This avoids the problem of light being partially blocked by the cable and then reflecting off it, preventing it from reaching the cable. Furthermore, because the width of the upper and lower reflectors is much larger than the cable's diameter, the arc of the focused light hitting the cable is greater than a certain degree, ensuring that the light reaches every part of the cable.

[0031] 3. This wire coating UV curing equipment allows for adjustment of the reflector angle via a rotary knob. This adjustment causes different reflection angles when light hits the reflector. Rotating the reflector clockwise increases the distance between the upper and lower reflectors and the previous two sections of reflection. This increases the indirect irradiation length and thus the indirect irradiation time, while keeping the overall irradiation time relatively constant. Since different paint materials consume different amounts of oxygen in their oxygen inhibition reaction, the time required to generate peroxy free radicals also varies. Therefore, the reflector angle can be adjusted to suit different paints. Attached Figure Description

[0040] 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.

[0041] like Figure 1-7 As shown, the device includes a housing 10, inside which a focusing tube 20 is fixed. A light source mounting block 101 is also fixed on the upper surface of the housing 10. A light source assembly and a reflector assembly are provided inside the housing 10. Heat dissipation vents 102 are provided on both sides of the light source mounting block 101. A cooling fan is provided inside the heat dissipation vents 102 for cooling the power supply compartment 30.

[0042] The reflective components are all housed inside the focusing tube 20, which includes an adjustable reflector 40, an upper reflector 41, and a lower reflector 42. The adjustable reflector 40 rotates within the focusing tube 20 at an angle of 10°-30°. The upper reflector 41 and the lower reflector 42 slide within the focusing tube 20. The focusing tube 20 is divided into two parts, each with a semi-circular cross-section. The two parts combine to form a hollow cylindrical structure with a relatively smooth interior, providing a certain mirror effect for additional light focusing. Slide rails 201 are provided at the ends of the focusing tube 20, and the upper reflector 41 and the lower reflector 42 are located within the slide rails 201. By setting up the focusing tube 20, the light generated by the diffused light source can be concentrated, increasing the curing effect of the paint. It can also isolate a certain amount of dust, preventing it from affecting the curing paint and causing defects such as blistering and cracking after curing.

[0043] The upper reflector 41 is located on the upper slide rail 201, and the lower reflector 42 is located on the lower slide rail 201. The opposite end faces of the upper reflector 41 and the lower reflector 42 are both arc-shaped. The arc-shaped surfaces of the upper reflector 41 and the lower reflector 42 are both mirror-shaped and used to reflect light. Their arc-shaped design can produce a certain focusing effect on the direct light, causing the light to converge at the center line of the length direction of the upper reflector 41. This avoids the problem that the light cannot continue to shine on the cable after being partially blocked by the cable. Moreover, since the width of the upper reflector 41 and the lower reflector 42 is much larger than the diameter of the cable, the arc of the light generated after the direct light is focused on the cable is greater than 180 degrees, ensuring that the light can shine on every part of the cable.

[0044] By adjusting the settings of reflector 40, upper reflector 41, and lower reflector 42, light can be reflected at least three times. When the light shines directly onto the cable, it illuminates the upper part of the cable. The light reflected by reflector 40 illuminates the lower part of the cable. The light reflected by upper reflector 41 illuminates the upper part of the cable again, and the light reflected by lower reflector 42 illuminates the lower part of the cable again, thus completing the segmented and comprehensive illumination of the cable paint. The reflection settings increase light utilization and significantly reduce energy consumption of the light source. Segmented illumination through reflection divides the curing process into multiple stages. During free radical photocuring, oxygen inhibits the curing reaction. Oxygen inhibition (OX) occurs when oxygen reacts with photo-induced reactive free radicals to generate stable peroxy free radicals, thus terminating the polymerization reaction. Prolonged, continuous irradiation at the same location continuously consumes oxygen for the reaction, leading to an oxygen-inhibited state both inside and outside the cable, preventing effective curing and resulting in insufficient curing. Segmented curing, on the other hand, rapidly consumes oxygen on the paint surface during the first irradiation, allowing the reaction to continue through un-irradiated areas, forming a protective film that isolates oxygen. When the un-irradiated areas are irradiated again, the oxygen content inside the cable paint is significantly reduced, resulting in a better and more complete curing reaction.

[0045] An adjusting block 104 is fixed to the front of the equipment housing 10. An adjusting shaft 401 is rotatably connected inside the focusing tube 20. The adjusting shaft 401 passes through the equipment housing 10 and into the adjusting block 104. One end of the adjusting shaft 401 is connected to the adjusting reflector 40, and the other end is fixed with a worm gear 402. A worm 403 also rotates inside the adjusting block 104. The worm 403 passes through the adjusting block 104 to the outside. An adjusting knob 404 is fixed to the outside part of the worm 403. The worm 403 cooperates with the worm gear 402. By rotating the adjusting knob 404, the angle of the adjusting reflector 40 can be adjusted. The angle at which light is reflected onto the adjustable reflector 40 varies. When the adjustable reflector 40 is rotated clockwise, the distance between the two ends of the upper reflector 41 and the lower reflector 42 and the previous two sections of reflection increases. With a small change in the overall illumination time, the indirect length of the indirect illumination is increased, thereby increasing the indirect illumination time. Since different paint materials consume different amounts of oxygen in their oxygen inhibition reaction, the time for generating peroxy free radicals also varies. Therefore, the angle of the adjustable reflector 40 can be adjusted to suit different paints.

[0046] The light source assembly is housed within the light source mounting block 101, with its light-emitting portion angled to emit a beam of light at an oblique angle. The light source assembly also includes a light-shielding group. The light source assembly includes a power supply compartment 30 installed inside the light source mounting block 101. A light source emitting block 31 is located at the bottom of the power supply compartment 30. The bottom of the light source emitting block 31 is angled, and its bottom end face has a light source inner groove 311. Several light sources are arranged at the bottom of the light source inner groove 311. The restriction of the light source inner groove 311 allows the light sources to illuminate a straight line and reduces diffuse scattering. The light source emitting block 31 is located inside the focusing tube 20. The light-shielding group is located on both sides of the light source emitting block 31 and includes an extension plate 312. A light-shielding plate groove 3122 is formed inside the extension plate 312, and several electromagnets 3121 are arranged on both end faces of the extension plate 3122. The electromagnets 3121 are electrically connected to an external switch via wires. At least two light-shielding plates 3123 are slidably arranged inside the light-shielding plate groove 3122 to block light. The plates 3123 are evenly and symmetrically arranged. A limiting rod 3124 is fixed in the light-shielding plate groove 3122. The limiting rod 3124 passes through all the light-shielding plates 3123. The light-shielding plates 3123 slide on the limiting rod 3124. The light-shielding plates 3123 and the limiting rod 3124 are connected together by a spring. The energization and de-energization state of the electromagnets 3121 is controlled by an external control element. When the power supply compartment 30 is started, all the electromagnets 3121 are energized, attracting the light-shielding plates 3123 and compressing the springs, so that the entire inner groove 311 of the light source is exposed. The individual electromagnets 3121 can be de-energized by the external control element. Under the action of the spring, the light-shielding plates 3123 on both sides abut together, thereby achieving the effect of light shielding. The length of the entire wire harness is controlled by the light shielding effect, so that the length of light shining on the cable is also shortened. This allows control over the time required for the paint to be irradiated, so as to adapt to the different curing times required by different paints.

[0047] Support wheels 103 are also installed on both sides of the equipment housing 10, which can be used to remove and install the upper reflector 41 and the lower reflector 42, making it convenient to replace the upper reflector 41 and the lower reflector 42 of different lengths. When a longer curing time is required, the extended upper reflector 41 and the lower reflector 42 can be installed to make it reflect more times, thereby increasing the curing time. The cable is located on the support wheel 103 and is located at the center of the focusing tube 20.

[0048] The focusing tube 20 is also provided with a sliding groove 202, in which a sliding rod 51 and a brush block 50 are slidably mounted. The brush block 50 is fixed on the sliding rod 51, which is equipped with a handle. The bottom of the brush block 50 is provided with bristles. By sliding the sliding rod 51, the brush block 50 can be moved, thereby cleaning the dirt on the surface of the lower reflector 42 and the adjusting reflector 40 through the brush bristles. During long-term use, the paint may not be fully cured and some residue may fall off. When the residue and dust fall on the lower reflector 42 and the adjusting reflector 40, it will greatly affect their reflective effect. Therefore, cleaning with the brush block 50 can keep the surface of the lower reflector 42 and the adjusting reflector 40 clean. The equipment housing 10 is also provided with a baffle 12. The upper end of the baffle 12 is set with an incline. The residue brushed off by the brush block 50 will fall into the space at the bottom of the baffle 12 for centralized treatment.

[0049] Working principle: During use, after the cable is dipped in paint, it passes through the support wheel 103 and is pulled by an external cable winding device. At the same time, it is at the center line of the focusing tube 20. Then, the device is turned on, the power compartment 30 is started, and the light source in the light source emitting block 31 is turned on, which emits parallel light rays. The light rays first illuminate the upper half of the cable, and then illuminate the adjusting reflector 40. By adjusting the reflection of the reflector 40, the light rays first illuminate the lower half of the cable, and then illuminate the upper reflector 41. The upper reflector 41 also reflects the light onto the upper half of the cable and the lower reflector 42. The lower reflector 42 reflects the light onto the lower half of the cable. At this time, the paint will undergo a curing reaction under the illumination of the light source, gradually solidify, and form a solid, completing the curing process of the silk-covered wire.

[0050] When it is necessary to adjust the angle of the reflector 40, the worm gear 403 is driven by rotating the adjustment knob 404 to rotate the worm wheel 402, which in turn drives the reflector 40 to rotate through the adjustment shaft 401, thereby adjusting the angle of the reflector 40 to adjust the appropriate light interval distance. When it is necessary to adjust the light duration, the electromagnet 3121 can be de-energized by an external control element, so that the two light-shielding plates 3123 are pushed together by the spring to block the light and shorten the overall light length, thereby shortening the length of light that shines on the cable, and thus shortening the time that the paint on the cable is exposed to light.

[0051] When the device is turned off, all electromagnets 3121 are de-energized, and all light-shielding plates 3123 will come together to block the inner groove 311 of the light source.

[0052] In summary, this wire coating UV curing equipment, by adjusting the settings of reflectors 40, 41, and 42, allows light to be reflected at least three times. When light shines directly onto the cable, it illuminates the upper part of the cable. Light reflected by reflector 40 illuminates the lower part of the cable, light reflected by upper reflector 41 illuminates the upper part again, and light reflected by lower reflector 42 illuminates the lower part again, completing segmented and comprehensive coating of the cable coating. This reflection setup increases light utilization and significantly reduces energy consumption. The curved surfaces of upper and lower reflectors 41 and 42 are mirrored to reflect light. Their curved surfaces also create a focusing effect on the direct light, converging it along the center line of the upper reflector 41. This prevents light from being blocked by the cable and then reflecting back to illuminate the cable. The problem is that, since the width of the upper reflector 41 and the lower reflector 42 is much larger than the diameter of the cable, the arc of the light that is focused on the cable after direct light is focused must be greater than 180 degrees to ensure that the light can reach every part of the cable. The angle of the reflector 40 can be adjusted by rotating the adjustment knob 404, so that the reflection angle produced by the light hitting the adjustment reflector 40 is different. When the adjustment reflector 40 is rotated clockwise, the distance between the two ends of the upper reflector 41 and the lower reflector 42 and the previous two sections of reflection is increased. When the overall illumination time changes little, the indirect length of the indirect illumination is increased, thereby increasing the indirect illumination time. Since different paint materials consume different amounts of oxygen in the oxygen inhibition reaction, the time for generating peroxy free radicals is also different. Therefore, the angle of the reflector 40 can be adjusted to adapt to different paints.
