Description

Technical Field

[0001] The invention relates to the technical field of silk-covered wire production, in particular to a silk-covered wire paint light-curing device. Background Art

[0002] Silk-covered wire is a kind of electromagnetic wire, whose conductor is wrapped with natural silk or fiber silk (such as nylon, polyester fiber, natural silk, self-adhesive silk, etc.) as an insulating layer.

[0003] Today's silk covered wire process is as follows: Step 1: Paying off the wire, releasing the wire from the coil, and automatically paying it off through a pay-off machine; Step 2: Straighten the bent wire using a straightening machine to facilitate subsequent operations; Step 3: Painting: Apply the first coat of paint on the wire; Step 4: Wrapping. During the first coat of paint, the wire needs to be naturally 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; Step 5: Paint, apply a second coat of paint on the insulation material; Step 6: Baking: The second coat of paint is dried by heat treatment equipment to solidify the paint. The wire is wound seven to eight times with a guide wheel and dried multiple times. The wire is painted once more during the second or third coat of paint, and then the third coat of paint is applied. Step 7: Winding up the wires. Wind the processed wires together through the coil winding equipment to complete the processing.

[0004] The production process is complicated, requiring multiple painting processes and multiple drying processes, and the drying time is long, which affects the processing time and greatly reduces the processing efficiency.

[0005] In the above processing, the paint is dried by heating the wire, which consumes a lot of energy. In addition, the drying process requires eight turns of winding 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 destroy its pressure resistance hardness and its bending stress, resulting in reduced wire quality after production.

[0014] Preferably, a slide groove is provided in the focusing tube, a slide rod and a brush block are slidably provided in the slide groove, the brush block is fixed on the slide rod, a handle is provided on the slide rod, and bristles are provided at the bottom of the brush block.

[0015] Preferably, heat dissipation openings are provided on both sides of the light source mounting block, and heat dissipation fans are provided in the heat dissipation openings.

[0016] Preferably, support wheels are installed on both sides of the equipment box, and one of the primary end faces of the equipment box is provided with an equipment box, the size of which is consistent with the slide rail, wherein the cable is located on the support wheels and at the center of the focusing tube.

[0017] Compared with the prior art, the present invention provides a silk-covered wire paint light curing device, which has the following beneficial effects: 1. The silk-covered wire paint light curing equipment can reflect light at least three times by adjusting the settings of the reflector, the upper reflector and the lower reflector. When the light is directly irradiated onto the cable, it can illuminate the upper part of the cable. By adjusting the light reflected by the reflector, it 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, completing the segmented and comprehensive irradiation of the cable paint. The reflection setting can increase the utilization rate of light and greatly reduce the energy consumption of the light source.

[0018] 2. The silk-covered wire paint light-curing equipment has an upper reflector and a lower reflector with mirror-shaped curved surfaces for reflecting light. The curved surface setting can produce a certain focusing effect on direct light, so that the light is gathered toward the center line of the length direction of the upper reflector, which can avoid the problem that the light cannot continue to shine on the cable after being blocked by the cable. Moreover, since the width of the upper reflector and the lower reflector is much larger than the diameter of the cable, the arc of the light generated after the direct light is focused and shining on the cable is greater than degrees, ensuring that the light can shine on every position of the cable.

[0019] 3. The silk-covered wire paint light curing equipment can adjust the angle of the adjusting reflector by rotating the adjusting knob, so that the reflection angle produced by the light irradiating the adjusting reflector is different. When the adjusting reflector is rotated clockwise, the distance between the two ends of the upper reflector and the lower reflector and the previous two sections of reflective irradiation can be increased. When the overall irradiation time changes little, the indirect length of the indirect irradiation is increased, thereby increasing the indirect irradiation time. Since different paint materials consume different amounts of oxygen in the oxygen inhibition reaction, the time for generating peroxyl free radicals is also different, so the angle of the adjusting reflector 40 can be adjusted to adapt to different paints.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-7As shown, it includes an equipment box 10, a focusing tube 20 is fixed inside the equipment box 10, a light source mounting block 101 is also fixed on the upper end surface of the equipment box 10, a light source assembly and a reflective assembly are arranged in the equipment box 10, heat dissipation ports 102 are also arranged on both sides of the light source mounting block 101, and a heat dissipation fan is arranged in the heat dissipation port 102 for dissipating the heat from the power supply compartment 30.

[0024] The reflective components are all arranged in the focusing tube 20, which includes an adjustable reflector 40, an upper reflector 41 and a lower reflector 42, wherein the adjustable reflector 40 rotates in the focusing tube 20, and its rotation angle is 10°-30°. The upper reflector 41 and the lower reflector 42 slide in the focusing tube 20. The focusing tube 20 is divided into two parts, and its cross-section is two semicircular. The two parts are combined to form a hollow cylindrical setting. The interior is relatively smooth and has a certain mirror effect for additional focusing effect. Slide rails 201 are provided on the end faces of the two ends of the connecting part of the focusing tube 20. The upper reflector 41 and the lower reflector 42 are located in the slide rails 201. Through the setting of the focusing tube 20, the light generated by the full scattering of the light source can be gathered together to increase the curing effect of the paint. It can also isolate a certain amount of dust to prevent it from affecting the paint being cured and causing defects such as bulging and cracking of the paint after curing.

[0025] The upper reflector 41 is located on the upper side slide rail 201, and the lower reflector 42 is located on the lower side slide rail 201. The opposite end surfaces of the upper reflector 41 and the lower reflector 42 are both arc-shaped. The arc surfaces of the upper reflector 41 and the lower reflector 42 are both mirror-shaped and used to reflect light. The arc surface setting can make the direct light produce a certain focusing effect, so that the light is gathered toward the center line of the length direction of the upper reflector 41, which can avoid the problem that the light cannot continue to shine on the cable after being blocked by the cable. In addition, 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 and shines on the cable is greater than 180 degrees, ensuring that the light can shine on every position of the cable.

[0026] By adjusting the settings of the reflector 40, the upper reflector 41 and the lower reflector 42, the light can be reflected at least three times. When the light is directly irradiated onto the cable, the upper part of the cable can be irradiated. By adjusting the light reflected by the reflector 40, the lower part of the cable can be irradiated. The light reflected by the upper reflector 41 will irradiate the upper part of the cable again. The light reflected by the lower reflector 42 will irradiate the lower part of the cable again, completing the segmented and comprehensive irradiation of the cable paint. The reflection setting can increase the utilization rate of light and greatly reduce the energy consumption of the light source. The segmented irradiation produced by reflection can divide the curing process into multiple stages. In the free radical light curing process, oxygen will inhibit the curing reaction ( Oxygen inhibition), oxygen will react with the active free radicals generated by light to generate stable peroxy free radicals, thereby terminating the polymerization reaction of free radicals. Long-term continuous irradiation at the same place will continue to consume oxygen for reaction, resulting in oxygen inhibition inside and outside the cable, and the curing cannot be effectively completed, resulting in insufficient curing reaction and failure to meet the curing requirements. Segmented curing can quickly consume oxygen on the surface of the paint through the first irradiation to produce a reaction, and then it can end the reaction by passing through the unirradiated area, forming a protective film to isolate oxygen. When it is irradiated again, the oxygen content of the paint inside the cable paint will be greatly reduced, and its curing reaction effect will be better and the curing effect will be more sufficient.

[0027] The front side of the device box 10 is also fixed with an adjustment block 104, and an adjustment shaft 401 is rotatably connected in the focusing tube 20. The adjustment shaft 401 passes through the device box 10 to the adjustment block 104. One end of the adjustment shaft 401 is connected to the adjustment reflector 40, and the other end is fixed with a worm gear 402. A worm 403 is also rotatable in the adjustment block 104, and the worm 403 passes through the adjustment block 104 to the outside, and an adjustment knob 404 is fixed to the outside part. The worm 403 cooperates with the worm gear 402, and the angle of the adjustment reflector 40 can be adjusted by rotating the adjustment knob 404. The angle of reflection produced by the light irradiating the adjusting reflector 40 is different. When the adjusting 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 reflective irradiation can be increased. When the overall irradiation time changes little, the indirect length of the indirect irradiation is increased, thereby increasing the indirect irradiation time. Since different paint materials consume different amounts of oxygen in the oxygen inhibition reaction, the time for them to produce peroxyl free radicals is also different, so the angle of the adjusting reflector 40 can be adjusted to adapt to different paints.

[0028] The light source assembly is arranged in the light source mounting block 101, and its light emitting part is arranged obliquely to emit light beams obliquely, and a shading group is also arranged in the light source assembly. The light source assembly includes a power supply compartment 30 installed in the light source mounting block 101, and a light source emitting block 31 is arranged at the bottom of the power supply compartment 30. The bottom of the light source emitting block 31 is arranged in an inclined surface, and a light source inner groove 311 is arranged on the bottom end face thereof, and a plurality of light source lamps are arranged at the bottom of the light source inner groove 311. The light source lamps can be restricted by the light source inner groove 311 so as to illuminate a straight line and reduce the diffuse scattering condition thereof. The light source emitting block 31 is located in the focusing tube 20, and the shading group is located on both sides of the light source emitting block 31, and includes an extension plate 312, and a shading plate slide groove 3122 is provided in the extension plate 312, and a plurality of electromagnets 3121 are arranged on the end faces on both sides thereof, and the electromagnet 3121 is electrically connected to an external switch through a wire, and at least two shading plates 3123 are slidably arranged in the shading plate slide groove 3122, so as to shading The plates 3123 are an even number and are symmetrically arranged. A limiting rod 3124 is fixed in the shading plate slide slot 3122. The limiting rod 3124 runs through all the shading plates 3123. The shading plates 3123 slide on the limiting rod 3124. The shading plates 3123 and the limiting rod 3124 are connected together by a spring. The energizing and de-energizing states of the electromagnets 3121 are controlled by external control elements. When the power supply compartment 30 is started, all the electromagnets 3121 are energized, the shading plates 3123 are adsorbed and the compressed springs are compressed, so that the entire inner groove 311 of the light source is exposed. The de-energization of a single electromagnet 3121 can be controlled by external control elements. Under the action of the springs, the shading plates 3123 on both sides abut against each other, thereby achieving a shading effect. The shading effect is used to control the length of the entire wiring harness, so that the length irradiated to the cable is also shortened, thereby controlling the irradiation time of the paint, thereby achieving the purpose of adapting to the different curing times required for different paints.

[0029] Support wheels 103 are also installed on both sides of the equipment box 10. One of the primary end surfaces of the equipment box 10 is provided with an equipment box 105, which is consistent in size with the slide rail 201 and can be used to disassemble and install the upper reflector 41 and the lower reflector 42, so as to facilitate the replacement of upper reflectors 41 and lower reflectors 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 them reflect more times, thereby increasing the curing time. The cable is located on the support wheel 103 and at the center of the focusing tube 20.

[0030] A slide groove 202 is also provided in the focusing tube 20, and a slide rod 51 and a brush block 50 are slidably provided in the slide groove 202. The brush block 50 is fixed on the slide rod 51, and a handle is provided on the slide rod 51. Bristles are provided at the bottom of the brush block 50, and the brush block 50 can be moved by sliding the slide rod 51, so that the dirt on the surface of the lower reflector 42 and the adjustable reflector 40 can be cleaned by the bristles. When used for a long time, the paint will not be completely cured and a certain amount of debris will fall off. When the debris and dust fall on the lower reflector 42 and the adjustable reflector 40, their reflective effect will be greatly affected. Therefore, the cleaning of the brush block 50 can keep the surface of the lower reflector 42 and the adjustable reflector 40 clean. A baffle 12 is also provided in the equipment box 10, and the upper end surface of the baffle 12 is set as an inclined surface. The debris brushed off by the brush block 50 will fall into the space at the bottom of the baffle 12 for centralized processing.

[0031] Working principle: When in use, after the cable is dipped in paint, it passes in and out from the support wheel 103, and is pulled by an external wire-winding device. At the same time, it is also at the center line of the focusing tube 20. Then the equipment is turned on, the power compartment 30 is started, and the light source lamp in the light source emitting block 31 is turned on to emit parallel light, so that it first shines on the upper half of the cable, and then shines on the adjusting reflector 40. By adjusting the reflection of the reflector 40, it first shines on the lower half of the cable, and then shines on the upper reflector 41. The upper reflector 41 also reflects and shines on the upper half of the cable and the lower reflector 42. The lower reflector 42 reflects and shines on the lower half of the cable. At this time, the paint will produce a curing reaction through the irradiation of the light source, gradually solidify, form a solid, and complete the curing process of the silk covered wire.

[0032] When it is necessary to adjust the angle of the reflector 40, the worm 403 drives the worm wheel 402 to rotate by rotating the adjusting knob 404, so that the reflector 40 can be driven to rotate by the adjusting shaft 401, so as to adjust the angle of the reflector 40 and adjust the appropriate lighting interval distance. When it is necessary to adjust the lighting duration, the electromagnet 3121 can be de-energized by an external control element, so that the two shading plates 3123 are abutted together under the thrust of the spring to shield the light and shorten the overall length of the light, thereby shortening the length of the light irradiated on the cable, and thus shortening the time that the paint on the cable is exposed to light.

[0033] When the device is turned off, all the electromagnets 3121 lose power, and the shading plates 3123 all come into contact with each other to block the inner groove 311 of the light source.

[0034] In summary, the silk-covered wire paint photocuring equipment can reflect light at least three times by adjusting the settings of the reflector 40, the upper reflector 41 and the lower reflector 42. When the light is directly irradiated onto the cable, the upper part of the cable can be irradiated. The light reflected by the reflector 40 can be irradiated onto the lower part of the cable by adjusting the light reflected by the upper reflector 41. The light reflected by the lower reflector 42 can irradiate the lower part of the cable again, thereby completing the segmented and comprehensive irradiation of the cable paint. The reflection setting can increase the utilization rate of light and greatly reduce the energy consumption of the light source. The arc-shaped surfaces of the upper reflector 41 and the lower reflector 42 are both mirror-shaped settings for reflecting light. The arc-shaped settings can make the direct light produce a certain focusing effect, so that the light is gathered at the center line of the length direction of the upper reflector 41, which can avoid the light being unable to continue to irradiate the cable after being blocked by the cable after reflection. The above problem is solved, and because 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 concentrated and irradiated on the cable is greater than 180 degrees, ensuring that the light can irradiate every position of the cable; the angle of the adjustable reflector 40 can be adjusted by rotating the adjusting knob 404, so that the reflection angle generated by the light irradiating on the adjustable reflector 40 is different. When the adjustable reflector 40 is rotated clockwise, the distance between the reflective irradiation at both ends of the upper reflector 41 and the lower reflector 42 and the previous two sections of reflective irradiation can be increased. When the overall irradiation time changes little, the indirect length of the indirect irradiation is increased, thereby increasing the indirect irradiation time. Since the oxygen consumed by the oxygen inhibition reaction of different paint materials is different, the time for generating peroxyl free radicals is also different, so the angle of the adjustable reflector 40 can be adjusted to adapt to different paints.
