DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all.

[0032] Reference Figures 1-10 A UV curing machine, comprising a curing box 1 and a support 10, the curing box 1 is installed on the top of the side wall of the support 10, the conveying belt body 9 is rotatably installed on the top of the inner side wall of the support 10, a plurality of second electric telescopic rods 17 are connected to the top end of the inner wall of the curing box 1, the extending end of the second electric telescopic rod 17 is connected with the top plate 18, the outer wall of the top plate 18 is connected with the UV lamp tube 27, and the outer wall of the UV lamp tube 27 is provided with a reflective mechanism.

[0033] As a technical optimization scheme of the present application, the reflecting mechanism comprises the first reflecting sheet 22 and the second reflecting sheet 26, both of which are arranged in an arc shape, one first reflecting sheet 22 is rotatably installed on the outer wall of the top plate 18 through a first electric rotating rod 21, and one second reflecting sheet 26 is rotatably installed on the outer wall of the top plate 18 through another first electric rotating rod 21, and the inner wall of the first reflecting sheet 22 is provided with an enhancement mechanism. When curing operation is needed and the volume of the element is moderate, the first reflecting sheet 22 and the second reflecting sheet 26 are unfolded outwardly by rotating the first electric rotating rod 21, and different unfolding angles can adjust the reflection intensity of the first reflecting sheet 22 and the second reflecting sheet 26 due to the arc shape of the first reflecting sheet 22 and the second reflecting sheet 26. After the first reflecting sheet 22 and the second reflecting sheet 26 are unfolded, the top end of the arc surface of the first reflecting sheet 22 and the second reflecting sheet 26 can reflect the ultraviolet light emitted to the two sides of the oblique angle above the UV lamp tube 27 to the bottom of the curing box 1, and the concave part of the arc surface of the first reflecting sheet 22 can reflect the ultraviolet light to the bottom of the curing box 1, and after the ultraviolet light is reflected to the inner wall top end of the arc surface of the other first reflecting sheet 22, it is reflected to the inside of the curing box 1 through the inner wall top end of the arc surface of the other first reflecting sheet 22. The mutual reflection between the two arc surfaces of the first reflecting sheet 22 can utilize the ultraviolet light emitted by the UV lamp tube 27, improve the curing efficiency of the curing box 1, and at the same time, by elongating the second electric telescopic rod 17, the UV lamp tube 27 can be pushed downward to make the distance between the UV lamp tube 27 and the element to be cured closer, and when the element to be cured is small, high-efficiency curing of the element can be realized without increasing the irradiation efficiency of the UV lamp tube 27, prolonging the service life of the UV lamp tube 27.

[0034] As a technical optimization scheme of the present application, the enhancement mechanism comprises the first auxiliary sheet 23 and the second auxiliary sheet 24, the first auxiliary sheet 23 is rotatably installed at the inner wall bottom end of the first reflecting sheet 22 through a second electric rotating rod 25, the second auxiliary sheet 24 is rotatably installed at the inner wall top end of the first auxiliary sheet 23 through another second electric rotating rod 25, and the first auxiliary sheet 23 and the second auxiliary sheet 24 are arranged in an arc shape. When the first reflecting sheet 22 and the second reflecting sheet 26 are unfolded, the first auxiliary sheet 23 and the second auxiliary sheet 24 will bear a part of the heat generated by the irradiation of the UV lamp tube 27 when they are not rotated, which can prevent the inner wall of the first reflecting sheet 22 and the second reflecting sheet 26 from being directly irradiated at a high temperature, affecting the reflection efficiency; when the element is too small, Figure 7As shown, by rotating the first auxiliary sheet 23 to the inner wall of the first reflective sheet 22 through the second electric rotating rod 25, the distance between the UV lamp tube 27 and the first reflective sheet 22 can be shortened, and the second auxiliary sheet 24 can be unfolded upward, the second auxiliary sheet 24 can further reflect the excess ultraviolet light obliquely upward and through the top of the arc surface of the first reflective sheet 22 to the bottom of the curing box 1, improving the reflection efficiency of the top of the arc surface of the first reflective sheet 22, and the combination of the second auxiliary sheet 24 and the first auxiliary sheet 23 can also absorb a large amount of direct heat of the UV lamp tube 27, which can prevent the temperature of the first reflective sheet 22 from being too high after long-time direct irradiation; when the temperature of the second auxiliary sheet 24 and the first auxiliary sheet 23 is high, such as Figure 6 As shown, the first auxiliary sheet 23 can be unfolded outward, and the second auxiliary sheet 24 can be retracted, at this time the first auxiliary sheet 23 bears the heat from the UV lamp tube 27, while the second auxiliary sheet 24 can be gradually cooled after being shielded by the first auxiliary sheet 23, and after the second auxiliary sheet 24 is cooled, the first auxiliary sheet 23 can be rotated upward, and the second auxiliary sheet 24 can shield the first auxiliary sheet 23, which can improve the reflection efficiency while preventing the temperature of the first reflective sheet 22 from being too high under direct irradiation of the UV lamp; when the element is too large, such as Figure 8 As shown, the first reflective sheet 22 is unfolded outward, the first auxiliary sheet 23 is unfolded downward, and the second auxiliary sheet 24 is unfolded downward, the first reflective sheet 22, the first auxiliary sheet 23 and the second auxiliary sheet 24 form an irregular arc surface, the second auxiliary sheet 24 can reflect the ultraviolet light obliquely upward to the top of the opposite first reflective sheet 22, and the first reflective sheet 22 reflects downward, while the second auxiliary sheet 24 reflects part of the ultraviolet light to the side wall of the element to be cured, improving the curing efficiency; after the curing work is completed, such as Figure 9 As shown, the first reflective sheet 22 and the second reflective sheet 26 can be rotated inward and retracted through the first electric rotating rod 21, so as to wrap the UV lamp tube 27 and prevent dust, and by adjusting the first auxiliary sheet 23 and the second auxiliary sheet 24, the first reflective sheet 22 and the second reflective sheet 26 can be wrapped more tightly, further improving the dust prevention efficiency.

[0035] As a technical optimization scheme of the present application, the outer wall bottom of the top plate 18 is connected with a plurality of third electric telescopic rods 19, the fixed end of the third electric telescopic rod 19 extends to the top end of the outer wall of the top plate 18, the extending end of the third electric telescopic rod 19 is fixed with a cleaning brush 20, and the cleaning brush 20 can contact the inner wall of the corresponding first reflective sheet 22 and second reflective sheet 26. The extension and shortening of the third electric telescopic rod 19 can clean the inner wall of the first reflective sheet 22 and the second reflective sheet 26 before the first reflective sheet 22 and the second reflective sheet 26 are adjusted. When brushing is not needed, the third electric telescopic rod 19 can be retracted, the cleaning brush 20 can be extended and attached to the bottom end of the outer wall of the top plate 18, so that the cleaning brush 20 does not affect the reflection efficiency of each first reflective sheet 22 and second reflective sheet 26, and the reflective sheet is cleaned before the curing operation starts. Dust will fall on the surface of the conveyor belt body 9 and be transported out by the conveyor belt body 9, and dust will not adhere to the surface of the element to be cured.

[0036] As a technical optimization scheme of the present application, the inner wall of the top end of the curing box 1 is provided with a first electric telescopic rod 12 between two adjacent UV lamp tubes 27 and at the side of the two end UV lamp tubes 27, and the extending end of the bottom of the first electric telescopic rod 12 is connected with a blocking plate 13. When the element to be cured is small, the blocking plate 13 can be extended by the first electric telescopic rod 12, and the two blocking plates 13 can be used to block the two sides of the UV lamp tube 27 to prevent heat loss. When the blocking plate 13 is not needed, the blocking plate 13 can be retracted by the first electric telescopic rod 12, so that the blocking plate 13 does not affect the unfolding of the reflective sheet.

[0037] As a technical optimization scheme of the present application, two insertion holes 14 are formed at one end of the outer wall of the blocking plate 13, the two insertion holes 14 face the feeding port of the conveyor belt body 9, and the two insertion holes 14 can be inserted with arc-shaped limiting pieces 16. When the element to be cured is too small, the two arc-shaped limiting pieces 16 can be inserted into the insertion holes 14, and the limiting piece 16 on the outer wall of one of the blocking plates 13 can be combined with the limiting piece 16 on the outer wall of the other blocking plate 13 on the adjacent side to form an opening for limiting and guiding the element, preventing the element from being offset on the surface of the conveyor belt body 9 when it is too small, and also improving the blocking effect of the blocking plate 13 by cooperating with the blocking plate 13, reducing heat loss, and isolating the UV lamp tubes 27 into independent spaces without affecting each other.

[0038] As a technical optimization scheme of the present application, the bottom end of the two side walls of the curing box 1 is provided with an air vent 15, the inner wall of the air vent 15 is fixed with a filter screen, and the inner wall of the air vent 15 is provided with an electric valve. The opening and closing of the air vent 15 can be realized by opening and closing the electric valve. When the curing work of the curing box 1 is completed, the electric valve can be opened to ensure the gas flowability in the curing box 1, thereby preventing the high concentration of ozone in the curing box 1 from causing damage to the human body. At the same time, the filter screen can filter the flowing gas. It should be noted that during the curing process, the ozone concentration in the curing box 1 will continue to rise under the irradiation of the ultraviolet light of the UV lamp 27. When the concentration reaches a certain level, it will cause damage to the human body. After the air flowability is enhanced, the ozone in the curing box 1 will be discharged into the atmosphere, and the total amount of ozone in the curing box 1 is much smaller than the total amount of ozone in the air. At room temperature, the stability of ozone is poor and can be decomposed into oxygen, thereby being discharged into the air without affecting the ozone concentration in the air, thereby not damaging the human body. However, if the ozone concentration in the curing box 1 is too high and the temperature is high, the ozone will be discharged from the inlet and outlet of the curing box 1. During the discharge period, the ozone concentration is still high. At this time, if the workers inhale, it will affect the human body. If the workers inhale for a long time, it will cause symptoms such as sore throat, nosebleed, and chest tightness.

[0039] As a technical optimization scheme of the present application, the curing box 1 is connected with a conduit 2 at the top end of the outer wall, the other end of the conduit 2 is connected with an air pump 3, and the conduit 2 is connected with the air inlet of the air pump 3. The filter 4 is installed on the top end of the outer wall of the side of the curing box 1 close to the air pump 3, and the filter 4 is communicated with the air outlet of the air pump 3.

[0040] As a technical optimization scheme of the present application, the top of the support 10 is provided with a baffle 6 at both ends of the side edge, the top end of the baffle 6 is provided with a plurality of grooves 7, and the heating pipe 5 is installed between the two corresponding grooves 7 at the same end. The two ends of the heating pipe 5 are downwardly extended and connected with the side wall of the support 10.

[0041] As a technical optimization scheme of the present application, a hose is mounted at the outer bottom end of the filter 4, the other end of the hose is communicated with the heating pipes 5 at both ends respectively, and a plurality of flow-through openings 8 are formed at the outer wall bottom end of the heating pipes 5. When the air pump 3 is started, the air pump 3 sucks out the gas in the curing box 1 through the conduit 2, and then the gas is transported to the inside of the heating pipes 5 through the hose at the outer wall bottom end of the filter 4 after being filtered by the filter 4, and is discharged through the flow-through openings 8 at the outer wall bottom end of the heating pipes 5, so that the flowability of the gas in the curing box 1 can be improved, the damage to the human body caused by the excessively high ozone concentration can be prevented, the heat in the curing box 1 can be recycled, the hot air blown out through the flow-through openings 8 can be used to preheat the elements to be cured and blow away the dust adhered to the outside of the elements to be cured, in addition, the heating pipes 5 are arranged at both ends of the conveyor belt body 9, so that the elements can be preheated and secondarily cured before and after curing; and the baffle 6 can prevent the dust from adhering to the side wall of the element to be cured during actual use.

[0042] In use, the third electric telescopic rod 19 is controlled to be telescoped, the first and second reflective sheets 22 and 26 corresponding to the cleaning brush 20 are brushed by the cleaning brush 20, the cleaning brush 20 is retracted after brushing to adhere to the inner wall bottom end of the top plate 18, so as not to affect the reflective effect of the first and second reflective sheets 22 and 26, the conveyor belt body 9 and the air pump 3 are started, the electric valve in the air hole 15 is closed, and the UV lamp tube 27 is started, the element to be cured is placed on the surface of the conveyor belt body 9, the dust brushed off by the cleaning brush 20 is transported to the outside of the curing box 1 by the conveyor belt body 9, and the element to be cured is transported into the curing box 1.

[0043] The first and second reflective sheets 22 and 26 are unfolded by the first electric rotating rod 21, the top end of the arc surface of the first reflective sheet 22 can reflect the ultraviolet light emitted to the two sides of the inclined angle above the UV lamp tube 27 to the bottom of the curing box 1 after unfolding, the recessed part of the arc surface of the first reflective sheet 22 can reflect the ultraviolet light to the bottom of the curing box 1, and the ultraviolet light reflected by the inner wall bottom end of the arc surface of the first reflective sheet 22 to the inner wall top end of the arc surface of the other first reflective sheet 22 is reflected to the inside of the curing box 1 through the inner wall top end of the arc surface of the other first reflective sheet 22, the mutual reflection between the arc surfaces of the two first reflective sheets 22 can utilize the ultraviolet light emitted by the UV lamp tube 27, the curing efficiency of the curing box 1 is improved, and the service life of the UV lamp tube 27 is prolonged, and when the first and second auxiliary sheets 23 and 24 are not rotated, the first and second auxiliary sheets 23 and 24 can bear part of the heat generated by the irradiation of the UV lamp tube 27, so that the temperature of the inner wall of the first reflective sheet 22 is not too high, and the reflective efficiency is not affected.

[0044] When the size of the element is moderate, for example, Figure 6As shown, the second auxiliary sheet 24 will be the first to rise in temperature, and will expand outward, and the first auxiliary sheet 23 will contract, at which time the first auxiliary sheet 23 will be subjected to heat from the UV lamp tube 27, and the second auxiliary sheet 24 will be shielded by the first auxiliary sheet 23 and will gradually cool down. After the second auxiliary sheet 24 cools down, it can rotate the first auxiliary sheet 23 upward, and the second auxiliary sheet 24 will shield the first auxiliary sheet 23. Since the size of the element is moderate, the reflection of one of the second auxiliary sheet 24 or the first auxiliary sheet 23 during the alternating heat dissipation process can still ensure the curing efficiency, so that the reflection efficiency can be improved while preventing the reflector from being directly irradiated by the UV lamp and being affected by the high temperature to affect the reflection efficiency.

[0045] When the element to be cured is small, the second electric telescopic rod 17 is extended, the UV lamp tube 27 is pushed downward, and the UV lamp tube 27 is closer to the element to be cured. After the first reflector 22 and the second reflector 26 are expanded, as shown, Figure 7 As shown, the second auxiliary sheet 24 is expanded upward by the second electric rotating rod 25, the first auxiliary sheet 23 is rotated by the second electric rotating rod 25 toward the inner wall of the first reflector 22, the distance between the UV lamp tube 27 and the reflector can be shortened, and the second auxiliary sheet 24 can be expanded upward. The second auxiliary sheet 24 can further reflect the excess ultraviolet light obliquely upward and reflect it to the bottom of the curing box 1 through the top of the arc surface of the first reflector 22, thereby improving the reflection efficiency of the top of the arc surface of the first reflector 22. The first auxiliary sheet 23 can reflect the ultraviolet light of the UV lamp tube 27 to the bottom of the curing box 1, thereby enhancing the reflection efficiency of the top of the inner wall of the first reflector 22 at this time, and playing a role of auxiliary enhancement of reflection for the second auxiliary sheet 24. The first auxiliary sheet 23 and the second auxiliary sheet 24 combine to further concentrate the light for curing the smaller element. At the same time, the first electric telescopic rod 12 is extended, the blocking plate 13 is extended to the outside of the surface of the conveying belt body 9, and the two arc-shaped limiting sheets 16 are inserted into the insertion hole 14. The blocking plate 13 and the limiting sheet 16 can limit and guide the element, prevent the small element from deviating on the surface of the conveying belt body 9, and reduce the loss of heat through the blocking plate 13, and isolate the UV lamp tube 27 into independent spaces, and do not affect each other.

[0046] When the element to be cured is large, the second electric telescopic rod 17 is contracted, as shown, Figure 8As shown, the UV lamp tube 27 is moved upward, the first reflective sheet 22 is unfolded outward, the first auxiliary sheet 23 is unfolded downward, and the second auxiliary sheet 24 is unfolded downward, so that the first reflective sheet 22, the first auxiliary sheet 23 and the second auxiliary sheet 24 form an irregular curved surface. After being fully unfolded, the second auxiliary sheet 24 can reflect the ultraviolet light at an oblique angle upward to the top of the opposite first reflective sheet 22, and then the ultraviolet light is reflected downward by the first reflective sheet 22. Meanwhile, the second auxiliary sheet 24 reflects part of the ultraviolet light to the side wall with the curing element, so as to cure the side wall of the large element. After the first auxiliary sheet 23 is unfolded downward, the first auxiliary sheet 23 can reflect the ultraviolet light downward. At this time, the first auxiliary sheet 23 can reflect the ultraviolet light downward from two different angles with the first reflective sheet 22. The first auxiliary sheet 23 can enhance the reflection efficiency of the first reflective sheet 22. The first reflective sheet 22, the first auxiliary sheet 23 and the second auxiliary sheet 24 reflect the ultraviolet light from three different angles, so as to enhance the overall reflection efficiency.

[0047] Meanwhile, after the air pump 3 is started, the gas in the curing box 1 is sucked out through the conduit 2, filtered by the filter 4, and then delivered to the inside of the heating pipe 5 through the hose at the bottom end of the outer wall of the filter 4. The hot gas is blown out through the flow-through port 8 at the bottom end of the outer wall of the heating pipe 5, so as to preheat the element to be cured and blow away the dust adhered to the outside of the element to be cured. By arranging the air pump 3, the flowability of the gas in the curing box 1 can be improved, so as to prevent the ozone concentration from being too high to cause damage to the body.

[0048] When the curing work is completed, the electric valve in the air hole 15 is opened, and the air hole 15 is connected to the outside air, so as to blow away the dust in the curing box 1. Figure 9 As shown, the first reflective sheet 22 and the second reflective sheet 26 can be rotated inward and contracted by the first electric rotating rod 21, so as to wrap the UV lamp tube 27 and prevent dust. By adjusting the first auxiliary sheet 23 and the second auxiliary sheet 24, the first reflective sheet 22 and the second reflective sheet 26 can be wrapped more tightly. The element after curing can be stored in the support 10, and the element after curing can be protected from dust by the support 10 and the conveying belt main body 9, so as to prevent the element from occupying too much space.

[0049] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
