Description

Technical Field

[0001] The present application relates to the technical field of three-dimensional label manufacturing, and in particular to a three-dimensional label manufacturing process, equipment and label thereof. Background Art

[0002] Three-dimensional labels are a type of label that uses three-dimensional design to enhance visual hierarchy and touch. They are widely used in product packaging, brand logos, exhibition displays and other scenarios. They use light and shadow, concave and convex textures or perspective effects to attract attention. They are easier to remember than flat labels and enhance user interaction. At the same time, the multi-layer structure can also distinguish between primary and secondary information.

[0003] At present, three-dimensional labels include main fonts and secondary fonts. The main fonts are generally designed with concave and convex designs, and the secondary fonts are generally smaller and thinner. In the production process of three-dimensional labels, the corresponding substrate is first selected. The substrate is generally made of film, synthetic paper or coated paper, and then UV glue is printed on the surface of the substrate. After that, the electrochemical aluminum foil and the substrate are pressed together through the laminating equipment to combine the UV glue with the electrochemical aluminum foil, and then the UV glue and the electrochemical aluminum foil layer are cured by UV lamps, so that the secondary font and the main font are displayed on the surface of the substrate. Finally, the main font hot stamping area is processed twice through a embossing mold to form a concave and convex three-dimensional effect.

[0004] However, this production method will cause the secondary font to appear broken and the font to be incompletely displayed. In addition, the three-dimensional sense of the protruding part of the main font is weak, making it difficult to achieve a prominent and eye-catching effect. Summary of the invention

[0005] In order to improve the three-dimensional effect of a three-dimensional label, the present application provides a three-dimensional label manufacturing process, equipment and label thereof, which can make the secondary font display complete.

[0006] In the first aspect, the present application provides a three-dimensional label manufacturing process, which adopts the following technical solution: 1. A three-dimensional label manufacturing process, comprising the following steps: S1: Substrate treatment: corona treatment and primer coating on the substrate surface; S2: Cold stamping laser material: Cold stamping laser material on the treated substrate surface; S3: Digital printing four colors: The outer frame and the inner bottom layer are painted by a digital printing press; S4: Printing the first varnish: Apply the first varnish to the main font, the secondary font and the inner frame through a UV printer; S5: Printing the second varnish: Apply the second varnish to the main font, the secondary font and the inner frame that have been varnished for the first time; S6: Surface reverse oil: Apply reverse oil to the inner bottom layer and the outer frame surface; S7: Three-dimensional embossing: The main font and inner frame are pressurized by embossing mold.

[0007] By adopting the above technical solution, the present application not only pressurizes and protrudes the main font and the inner frame, but also covers the protruding parts with the first synergistic varnish and the second synergistic varnish, which can increase the protruding thickness of the main font and the inner frame. The bright light can also enhance the visual level, thereby further improving the three-dimensional sense of the protruding part. Moreover, under the matte contrast of the inner bottom layer, the bright parts of the main font and the secondary font can be further highlighted. The matte touch of the inner bottom layer and the smooth touch of the main font and the secondary font can enhance the texture.

[0008] This application uses the colors of the main font, secondary font and inner frame as the base color, and then uses a digital printing machine to color the inner bottom layer, so that the main font, secondary font and inner frame appear. Compared with the prior art, the material of the main font color is glued to the substrate through a cold stamping process. In this way, since the secondary font is smaller and thinner, the material pasted on the secondary font is easier to be peeled off during the process of peeling off the excess material after the material is pasted, so that the secondary font is more likely to be broken and incomplete. The present application reduces the peeling after pasting, so that the secondary font is displayed complete.

[0009] Compared with the prior art, which requires three steps to stick the inner bottom layer, outer frame and fonts to the paper through the cold stamping process, the present application can simplify the steps and complete it in two steps. At the same time, it can also be more flexible and can meet the needs of more complex designs or designs with finer lines.

[0010] Preferably, in the step of printing the first varnish, the nozzle applies the varnish to the main font, the secondary font and the outer layer of the inner frame, and then the sprayed varnish is cured by a UV lamp assembly.

[0011] By adopting the above technical solution, when the nozzle is coating varnish, the UV lamp assembly irradiates the varnish at the same time, so that the varnish can be cured quickly and the dispersion of the varnish can be reduced.

[0012] In the second aspect, the present application provides a three-dimensional label using the following technical solution: The invention comprises a substrate, a laser layer is cold-stamped on the surface of the substrate, an outer frame is printed on the surface of the laser layer, an inner bottom layer is printed in the middle of the surface of the laser layer, an inner frame is reserved between the outer frame and the inner bottom layer, a main font is reserved in the middle of the inner bottom layer, and secondary fonts are reserved at the top and the bottom of the inner bottom layer respectively; the outer layers of the inner frame, the main font and the secondary font are printed with a first varnish layer and a second varnish layer in sequence respectively, and the inner frame and the main font protrude outwards.

[0013] By adopting the above technical solution, the contents of the main font and the secondary font in the inner frame are more prominent against the backdrop of the outer frame and the inner bottom layer. The main font is located in the middle and protrudes outward. With the assistance of bright light, the main font is more prominent, thereby enhancing the three-dimensional sense of the label, attracting the user's attention and strengthening the user's memory. The main font is the product name. After the user remembers the product name, the product's popularity can be improved. The second most eye-catching thing is the secondary font located at the top and bottom of the main font. The secondary font is a further description of the product, which enhances the user's further understanding of the product.

[0014] Preferably, the outer side of the outer frame and the inner bottom layer are respectively coated with a reverse oil layer.

[0015] By adopting the above technical solution, the reverse oil reacts with the base oil to form a matte texture, so that the outer frame and the inner bottom layer form a matte area, and at the same time, a frosted touch can be produced.

[0016] In a third aspect, the present application provides a three-dimensional label manufacturing device using the following technical solution: It includes an organism, a mounting frame is slidably connected to the top of the organism, a nozzle assembly is arranged at one end of the bottom surface of the mounting frame, a UV lamp assembly is arranged at the other end of the bottom surface of the mounting frame, the UV lamp assembly includes a first UV lamp unit, a second UV lamp unit and a third UV lamp unit, the light irradiated by the first UV lamp unit is aimed at the bottom of the output end of the nozzle assembly, the light irradiated by the second UV lamp unit is irradiated directly below, and the light irradiated by the third UV lamp unit is away from one end of the nozzle assembly.

[0017] By adopting the above technical solution, when the nozzle assembly is printing, the light irradiated by the first UV lamp unit can be aimed at the varnish just sprayed, so that the light irradiated by the first UV lamp unit can fix the varnish just sprayed in time, and when the varnish just sprayed is blown by the wind or shaken, the dispersion of the varnish just sprayed can be reduced. Afterwards, when the nozzle assembly moves along the printing direction to print the next point, the light of the second UV lamp unit continues to irradiate the varnish sprayed from the previous printing point, and the varnish fixed by the first UV lamp unit is cured. When the nozzle assembly continues to move along the printing direction, the light of the third UV lamp unit continues to irradiate the varnish baked by the second UV lamp unit. When printing, the nozzle assembly moves at a faster speed. Under the action of the third UV lamp unit, the varnish can be further irradiated, reducing the situation where the varnish is not completely cured due to the faster movement of the second UV lamp unit.

[0018] Preferably, the UV lamp assembly includes a shell and two first reflectors, the shell is mounted on the bottom surface of the mounting frame at one end away from the nozzle assembly, the two first reflectors are mounted on the bottom surface of the shell in parallel with each other, the first reflectors are tilted, and the tilt direction of the first reflectors is from top to bottom toward the printing direction, and the first UV lamp unit is arranged between the two first reflectors.

[0019] By adopting the above technical solution, under the action of the first reflector, the path of the light irradiated by the first UV lamp unit can be guided, so that the light irradiated by the first UV lamp unit is gathered at the bottom of the output end of the nozzle assembly, so that the light of the first UV lamp unit can better irradiate the varnish just sprayed.

[0020] Preferably, the UV lamp assembly includes two second reflectors, which are relatively parallelly mounted on the bottom surface of the shell away from one end of the first reflector, the second reflectors are tilted, and the inclination direction of the second reflectors is from top to bottom in the opposite direction of printing, the second UV lamp unit is arranged between the first reflector and the second reflector, and the third UV lamp unit is arranged between the two second reflectors.

[0021] By adopting the above technical solution, under the action of the second reflector, the first reflector and the second reflector converge the light of the second UV lamp unit at the bottom, and at the same time, can also diffuse it to increase the irradiation range of the second UV lamp unit, and the two second reflectors can guide the route of the light irradiated by the third UV lamp unit, thereby converging the light irradiated by the third UV lamp unit at one end away from the nozzle assembly, so that the light of the third UV lamp unit can better irradiate and cure the varnish.

[0022] Preferably, fins are installed on the top surface of the shell.

[0023] By adopting the above technical solution, the heat dissipation surface area is increased under the action of the fins, so that the contact between the air and the heat source is more complete, thereby improving the heat exchange efficiency, accelerating the heat transfer, and then improving the heat dissipation effect of the top surface of the shell, thereby reducing the temperature of the UV lamp assembly.

[0024] Preferably, a mounting groove is opened at one end of the fin near the top surface of the shell, a heat dissipation pipe is installed on the top surface of the shell, the heat dissipation pipe is adapted to be inserted into the mounting groove, one end of the heat dissipation pipe is connected to a water inlet pipe, and the other end of the heat dissipation pipe is connected to a water outlet pipe.

[0025] By adopting the above technical solution, water flows into the heat dissipation pipe from the water inlet pipe, then flows through the heat dissipation pipe cavity, and finally flows out from the water outlet pipe. Under the action of the water flow, the water flow absorbs the heat on the top surface of the outer shell, thereby reducing the temperature of the outer shell and further reducing the temperature of the UV lamp assembly.

[0026] Preferably, an exhaust fan is installed on the side wall of the housing.

[0027] By adopting the above technical solution, under the action of the exhaust fan, the exhaust fan can increase the air circulation, so that the heat on the fins can be quickly removed from the heat source area. At the same time, the exhaust fan can also accelerate the air flow, thereby improving the heat exchange efficiency between the fins and the air, and can quickly dissipate the heat of the fins, and then quickly dissipate the heat of the top surface of the shell and the UV lamp assembly.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application not only pressurizes and bulges the main font and the inner frame, but also covers the bulging parts with the first efficiencies varnish and the second efficiencies varnish, which can increase the bulging thickness of the main font and the inner frame, and the bright light can also enhance the visual level, thereby further improving the three-dimensional sense of the bulging parts, and under the matte contrast of the inner bottom layer, the bright parts of the main font and the secondary font can be further highlighted, and the frosted touch of the inner bottom layer and the smooth touch of the main font and the secondary font can enhance the texture.

[0029] This application uses the colors of the main font, secondary font and inner frame as the base color, and then uses a digital printing machine to color the inner bottom layer, so that the main font, secondary font and inner frame appear. Compared with the prior art, the material of the main font color is glued to the substrate through a cold stamping process. In this way, since the secondary font is smaller and thinner, the material pasted on the secondary font is easier to be peeled off during the process of peeling off the excess material after the material is pasted, so that the secondary font is more likely to be broken and incomplete. The present application reduces the peeling after pasting, so that the secondary font is displayed complete.

[0030] 2. When the nozzle assembly is printing, the light irradiated by the first UV lamp unit can be aimed at the varnish just sprayed out, so that the light irradiated by the first UV lamp unit can fix the varnish just sprayed out in time. When the varnish just sprayed out is blown by the wind or shaken, the dispersion of the varnish just sprayed out can be reduced. Afterwards, when the nozzle assembly moves along the printing direction to print the next point, the light of the second UV lamp unit continues to irradiate the varnish sprayed out of the previous printing point, and the varnish fixed by the first UV lamp unit is cured. When the nozzle assembly continues to move along the printing direction, the light of the third UV lamp unit continues to irradiate the varnish baked by the second UV lamp unit. When printing, the nozzle assembly moves at a faster speed. Under the action of the third UV lamp unit, the varnish can be further irradiated, reducing the situation where the varnish is not completely cured due to the faster movement of the second UV lamp unit.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses a three-dimensional label manufacturing process.

[0039] Reference Figure 1 , a three-dimensional label manufacturing process, comprising the following steps: S1: Substrate treatment: Select a corresponding substrate. In the embodiment of the present application, the substrate is paper. The surface of the paper is subjected to corona treatment to increase the surface tension of the paper and enhance its adhesion. Afterwards, a primer is applied to the surface of the corona-treated paper to further enhance the adhesion of the paper. At the same time, it can also reduce the subsequent penetration of the laser layer into the paper.

[0040] S2: Cold stamping laser material: The main font 13, the secondary font 14 and the inner frame 12 are of the same color. The color of the selected laser material is consistent with the color of the main font 13, the secondary font 14 and the inner frame 12. First, brush UV glue on the treated paper surface, and then press the laser material and the UV glue together. Combine the UV glue and the laser material, and then irradiate with a UV lamp to cure the UV glue. After the UV glue is cured, it is firmly bonded to the laser material.

[0041] S3: Four-color digital printing: The outer frame 11 and the inner bottom layer 15 are colored by a digital printing machine, so that the remaining uncolored parts are the main font 13, the secondary font 14 and the inner frame 12, thereby showing the main font 13, the secondary font 14 and the inner frame 12. At the same time, the background pattern on the inner bottom layer 15 can also be printed, so as to complete the drawing of the font and pattern of the label and complete the design content on the label surface. Compared with the prior art, the inner bottom layer 15, the outer frame 11 and the font are respectively glued to the paper through the cold stamping process, which is divided into three steps. The present application can simplify the steps and can be completed in two steps. At the same time, it can also be more flexible and can meet the needs of more complex designs or designs with thinner lines.

[0042] S4: Printing the first varnish: The printed label is transported to the UV printer, and the nozzle applies varnish to the main font 13, the secondary font 14 and the outer layer of the inner frame 12. The UV lamp assembly 3 then solidifies the sprayed varnish to complete the first coating of the enhanced varnish. Under the effect of the enhanced varnish, the high-gloss varnish can expand the printing color gamut, enhance the reflectivity of the metallic ink, and improve the smooth feel.

[0043] S5: Printing the second varnish: After the label of the first efficiencies varnish is completed, the second varnish is applied by UV printer. The second varnish is applied to the outer layer of the main font 13, the secondary font 14 and the inner frame 12, covering the outer side of the first efficiencies varnish. Under the effect of the second efficiencies varnish, the reflectivity of the main font 13, the secondary font 14 and the inner frame 12 can be enhanced, making the metal texture sharper, and improving the hardness of the main font 13, the secondary font 14 and the inner frame 12. After friction, scratches can be reduced, and the service life of the label can be extended. At the same time, the tactile difference between the main font 13, the secondary font 14 and the inner frame 12 can be improved, and the reflectivity and smooth feel of the metallic ink can be further enhanced.

[0044] S6: Surface reverse oil: After the second synergistic varnish is applied to the label, reverse oil is applied to the inner bottom layer 15 and the outer surface of the outer frame 11. The reverse oil reacts with the bottom base oil to form a matte texture. The bright texture of the main font 13, the secondary font 14 and the inner frame 12 is contrasted with the matte texture of the inner bottom layer 15 and the outer frame 11. The alternation of bright and matte textures can further highlight the main font 13 and the secondary font 14. At the same time, the contrast between smooth and matte touch can enhance the user experience.

[0045] S7: Three-dimensional embossing: The main font 13 and the inner frame 12 are pressurized by an embossing mold to make the main font 13 and the inner frame 12 protrude, thereby forming a concave-convex three-dimensional effect, thereby distinguishing primary and secondary information, and focusing the user's sight on the content in the inner frame 12. The protrusion of the main font 13 and the blessing of bright light enhance the three-dimensional effect of the main font 13, making the main font 13 more attractive to the user's sight, and at the same time, it is easier to be remembered, thereby enhancing the user's sense of interaction.

[0046] S8: Die cutting: Cut the label into the finished shape.

[0047] The present application not only pressurizes and protrudes the main font 13 and the inner frame 12, but also covers the protruding parts with the first synergistic varnish and the second synergistic varnish, which can increase the protruding thickness of the main font 13 and the inner frame 12. The bright light can also enhance the visual level, thereby further improving the three-dimensional sense of the protruding parts. Moreover, under the matte contrast of the inner bottom layer 15, the bright parts of the main font 13 and the secondary font 14 can be further highlighted. The frosted touch of the inner bottom layer 15 and the smooth touch of the main font 13 and the secondary font 14 can enhance the texture.

[0048] The present application uses the colors of the main font 13, the secondary font 14 and the inner frame 12 as the basic colors, and then uses a digital printing machine to color the inner bottom layer 15, so that the main font 13, the secondary font 14 and the inner frame 12 appear. Compared with the prior art, the material of the main font 13 color is adhered to the substrate through a cold stamping process. In this way, since the secondary font 14 is smaller and thinner, the material pasted on the secondary font 14 is easier to be peeled off during the process of peeling off the excess material after the material is pasted, so that the secondary font 14 is more likely to be broken and incomplete. The present application reduces the peeling after pasting, so that the secondary font 14 is displayed complete.

[0049] Also disclosed in an embodiment of the present application is a three-dimensional label, which is manufactured based on a three-dimensional label manufacturing process.

[0050] Reference Figure 1 A three-dimensional label includes a substrate. In the embodiment of the present application, the substrate is paper, a primer layer is coated on the surface of the paper, a laser layer is cold-stamped and pasted on the surface of the paper, the laser layer covers the outside of the primer layer, an outer frame 11 is printed on the surface of the laser layer, the outer frame 11 is located on the surface of the laser layer and is arranged along the outer edge, correspondingly, an inner bottom layer 15 is printed on the surface of the laser layer, the inner bottom layer 15 is located in the middle of the surface of the laser layer, a gap is reserved between the outer frame 11 and the inner bottom layer 15, the reserved gap is the inner frame 12, a space is reserved in the middle of the inner bottom layer 15, the space reserved in the middle of the inner bottom layer 15 is the main font 13, and gaps are reserved at the top and bottom of the inner bottom layer 15, respectively, and the reserved gaps are the secondary font 14, that is, after printing the outer frame 11 and the inner bottom layer 15, the remaining parts of the laser layer that appear are the inner frame 12, the main font 13 and the secondary font 14 respectively.

[0051] The outer layers of the inner frame 12, the main font 13 and the secondary font 14 are respectively printed with a first varnish layer and a second varnish layer, so that the surfaces of the inner frame 12, the main font 13 and the secondary font 14 are reflective, thereby forming a bright area, and at the same time, a smooth touch can be produced. The inner frame 12 and the main font 13 protrude outward, increasing the three-dimensionality of the inner frame 12 and the main font 13. Correspondingly, the outer sides of the outer frame 11 and the inner bottom layer 15 are respectively coated with a reverse oil layer, and the reverse oil reacts with the base oil to form a matte texture, so that the outer frame 11 and the inner bottom layer 15 form a matte area, and at the same time, a frosted touch can be produced.

[0052] Against the backdrop of the outer frame 11 and the inner bottom layer 15, the contents of the main font 13 and the secondary font 14 in the inner frame 12 are more prominent. The main font 13 is located in the middle and protrudes outward. With the help of bright light, the main font 13 is more prominent, which enhances the three-dimensional sense of the label, attracts the user's attention and strengthens the user's memory. The main font 13 is the product name. After the user remembers the product name, the popularity of the product can be improved. The second most eye-catching thing is the secondary font 14 located at the top and bottom of the main font 13. The secondary font 14 is a further description of the product, which enhances the user's further understanding of the product.

[0053] The embodiment of the present application also discloses a three-dimensional label manufacturing device, which is applied to the above-mentioned three-dimensional label manufacturing process.

[0054] Reference Figure 2 A three-dimensional label manufacturing device includes a body 2, a support frame 21 is slidably connected to the top of the body 2, the long side of the support frame 21 is parallel to the wide side of the body 2, and the support frame 21 can move back and forth along the long side of the body 2, and a mounting frame 22 is slidably connected to the support frame 21, and the mounting frame 22 can move back and forth along the long side of the support frame 21. A nozzle assembly 23 is arranged at one end of the bottom of the support frame 21, and the output end of the nozzle assembly 23 is aligned with the top surface of the body 2. Varnish is sprayed out through the output end of the nozzle assembly 23, and the printing of the first varnish layer and the second varnish layer can be completed.

[0055] Reference Figure 2 and Figure 3A stabilizing frame 24 is fixed at one end of the bottom of the mounting frame 22. The stabilizing frame 24 and the nozzle assembly 23 are sequentially arranged along the printing direction of the long side of the machine body 2. A UV lamp assembly 3 is installed at the bottom of the stabilizing frame 24. The UV lamp assembly 3 includes a shell 31, a UV lamp group, a first reflector group and a second reflector group. The stabilizing frame 24 has a storage cavity inside, which is connected from top to bottom. The stabilizing frame 24 is provided with an opening on the side away from the mounting frame 22, and the opening is connected with the storage cavity. The shell 31 is movably inserted into the stabilizing frame 24 from the opening. The shell 31 is located in the storage cavity. Slide bars are respectively fixed at both ends of the shell 31. Correspondingly, the two inner walls of the stabilizing frame 24 are respectively provided with slide grooves for inserting the slide bars. The slide bars can move along the long sides of the slide grooves, so that the shell 31 can be installed in the stabilizing frame 24 or taken out from the stabilizing frame 24.

[0056] The first reflector group is arranged at one end of the shell 31 close to the nozzle assembly 23, and the first reflector group includes two first reflectors 32. The two first reflectors 32 are relatively and parallelly installed on the bottom surface of the shell 31. The long sides of the first reflectors 32 are parallel to the long sides of the shell 31. The first reflectors 32 are inclined. The inclination direction of the first reflectors 32 is from top to bottom toward the printing direction. The two first reflectors 32 enclose a first irradiation cavity.

[0057] Correspondingly, the second reflector group is arranged at one end of the shell 31 away from the nozzle assembly 23, and the second reflector group includes two second reflectors 33, and the two second reflectors 33 are relatively and parallelly installed on the bottom surface of the shell 31, and the long sides of the second reflectors 33 are parallel to the long sides of the shell 31. The second reflectors 33 are inclined, and the inclination direction of the second reflectors 33 is from top to bottom in the opposite direction of printing. A second irradiation cavity is reserved between the first reflector group and the second reflector group, and a third irradiation cavity is enclosed between the two second reflectors 33.

[0058] Reference Figure 2 and Figure 3 The UV lamp group is installed on the bottom surface of the housing 31, and the UV lamp group includes a first UV lamp unit 34, a second UV lamp unit 35 and a third UV lamp unit 36. The first UV lamp unit 34 is located in the first irradiation cavity, and the light at the output end of the first UV lamp unit 34 is irradiated along the inclined direction of the first reflector 32. The second UV lamp unit 35 is located in the second irradiation cavity, and the light at the output end of the second UV lamp unit 35 is irradiated directly below. The third UV lamp unit 36 ​​is located in the third irradiation cavity, and the light at the output end of the third UV unit is irradiated along the inclined direction of the second reflector 33.

[0059] When the nozzle assembly 23 is printing, the light irradiated by the first UV lamp unit 34 can be aimed at the varnish just sprayed out, so that the light irradiated by the first UV lamp unit 34 can fix the varnish just sprayed out in time, and when the varnish just sprayed out is blown by the wind or shaken, the dispersion of the varnish just sprayed out can be reduced. Afterwards, when the nozzle assembly 23 moves along the printing direction to print the next point, the light of the second UV lamp unit 35 continues to irradiate the varnish sprayed out of the previous printing point, and the varnish fixed by the first UV lamp unit 34 is cured. When the nozzle assembly 23 continues to move along the printing direction, the light of the third UV lamp unit 36 ​​continues to irradiate the varnish baked by the second UV lamp unit 35. When printing, the nozzle assembly 23 moves at a faster speed. Under the action of the third UV lamp unit 36, the varnish can be further irradiated, reducing the situation where the varnish is not completely cured due to the faster movement of the second UV lamp unit 35.

[0060] Reference Figure 4 and Figure 5 When the UV lamp assembly 3 is working, it will generate more heat, resulting in a higher temperature of the UV lamp assembly 3, and the higher temperature will affect the service life of the UV lamp assembly 3. A heat dissipation assembly 4 is arranged on the top of the shell 31. The heat dissipation assembly 4 includes fins 41. The fins 41 are fixed on the top surface of the shell 31. Under the action of the fins 41, the surface area of ​​heat dissipation is increased, so that the contact between the air and the heat source is more complete, thereby improving the heat exchange efficiency, accelerating the heat transfer, and then improving the heat dissipation effect of the top surface of the shell 31, thereby reducing the temperature of the UV lamp assembly 3.

[0061] The fin 41 includes a wing ray 411, which is fixed to the top surface of the shell 31, and the long side of the wing ray 411 is parallel to the long side of the top surface of the shell 31. In the embodiment of the present application, the wing ray 411 is an isosceles trapezoidal wing, and the width of the wing ray 411 at one end close to the top surface of the shell 31 is greater than the width of the wing ray 411 at one end away from the top surface of the shell 31, thereby increasing the connection area with the top surface of the shell 31 and improving the connection stability between the wing ray 411 and the top surface of the shell 31. At the same time, the force area between the wing ray 411 and the top surface of the shell 31 can be increased, and the center of gravity of the wing ray 411 can be lowered, so that when the wing ray 411 is subjected to a force, the situation of the wing ray 411 falling off from the top surface of the shell 31 can be reduced. There are multiple wing rays 411, and the multiple wing rays 411 are evenly distributed along the wide side direction of the top surface of the shell 31.

[0062] A ventilation slot 412 is provided between two adjacent wing bars 411. The ventilation slot 412 is an isosceles trapezoidal slot. The width of the outer end of the ventilation slot 412 is greater than the width of the inner end of the ventilation slot 412. Under the action of the ventilation slot 412, the air flow distribution can be optimized, the resistance of air flow can be reduced, and the heat dissipation effect of the UV lamp assembly 3 can be improved.

[0063] Reference Figure 5 The heat dissipation assembly 4 also includes a heat dissipation pipe 42. The fin 41 is provided with a mounting groove at one end near the top surface of the shell 31. The heat dissipation pipe 42 is adapted to be inserted into the mounting groove. The heat dissipation pipe 42 is fixed between the top surface of the shell 31 and the fin 41. One side of the heat dissipation pipe 42 abuts against the side wall of the top surface of the shell 31. In the embodiment of the present application, the heat dissipation pipe 42 is a curved pipe. The heat dissipation pipe 42 extends from one end of the top surface of the shell 31 to the other end of the top surface of the shell 31, and then the heat dissipation pipe 42 turns back from the other end. One end is connected to the heat dissipation pipe 42, and the heat dissipation pipe 42 is connected to the water outlet pipe 422 at the other end. Water flows into the heat dissipation pipe 42 from the water inlet pipe 421, and then flows through the cavity of the heat dissipation pipe 42, and finally flows out from the water outlet pipe 422. Under the action of the water flow, the water flow absorbs the heat on the top surface of the shell 31, thereby reducing the temperature of the shell 31, and then reducing the temperature of the UV lamp assembly 3.

[0064] Exhaust fans 43 are respectively installed on one side of the two wide sides of the shell 31. The number of exhaust fans 43 depends on the specific scenario. In the embodiment of the present application, there are four exhaust fans 43. Two exhaust fans 43 are arranged at one end of the shell 31, and the other two exhaust fans 43 are arranged at the other end of the shell 31. The exhaust fans 43 at both ends are relatively staggered. The exhaust direction of the exhaust fans 43 is consistent with the long side direction of the ventilation slots 412. Under the action of the exhaust fans 43, the exhaust fans 43 can increase the air circulation, so that the heat on the fins 41 can be quickly removed from the heat source area. At the same time, the exhaust fans 43 can also accelerate the air flow, thereby improving the heat exchange efficiency between the fins 41 and the air, and can quickly dissipate the heat of the fins 41, and then quickly dissipate the heat of the top surface of the shell 31 and the UV lamp assembly 3.

[0065] Reference Figure 3 and Figure 4 , circulation grooves are respectively opened on both sides of the stable frame 24, the number of the circulation grooves is adapted to the number of the exhaust fans 43, and the circulation grooves correspond to the exhaust fans 43 one by one. Correspondingly, a movable groove for the water inlet pipe 421 and the water outlet pipe 422 to enter and exit is opened on one side of the stable frame 24.

[0066] The two ends of the stabilizing frame 24 away from the mounting frame 22 are rotatably connected with locking blocks 241. When the shell 31 needs to be installed in the stabilizing frame 24, the side wall of the locking block 241 abuts against the outer side of the slide bar, thereby limiting the slide bar and preventing the shell 31 from sliding out of the stabilizing frame 24. When the shell 31 needs to be taken out, the locking block 241 is rotated to move the locking block 241 away from the slide bar, and an outward force is applied to the shell 31, thereby taking the shell 31 out of the opening.

[0067] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
