DETAILED DESCRIPTION

[0022] As Figures 1-4As shown, the utility model provides a novel desktop type UV curing machine, include: frame 1, frame 1 upper end surface is equipped with conveying device 2, UV curing device 3 and guiding device 4, conveying device 2, UV curing device 3 and guiding device 4 are sequentially arranged along left and right direction, conveying device 2 includes: first support 5, conveying roller 6 and motor 7, first support 5 is fixed on frame 1 upper end surface, conveying roller 6 is rotatably arranged in first support 5, motor 7 is drivenly connected with conveying roller 6 to drive conveying roller 6 to rotate, guiding device 4 includes: second support 10 and guide rod 11, second support 10 is fixed on frame 1 upper end surface, guide rod 11 is arranged in second support 10, conveying roller 6 and guide rod 11 are parallel to each other. The conveying roller 6 and the guide rod 11 for conveying the printing support are arranged on the left and right sides of the UV curing device 3, the printing support is conveyed to the UV curing device 3 through the guide rod 11 for curing, and the cured printing support is conveyed to the conveying roller 6. Since the conveying roller 6 is provided with the motor 7 and can rotate, the speed of the printing support on the conveying roller 6 is different from the speed of the printing support on the guide rod 11. The tension of the printing support is adjusted by the conveying roller 6 and the guide rod 11, so that the printing support can remain flat during the curing process, thereby improving the curing effect of the printing support.

[0023] The UV curing device 3 includes a third support 8 and a UV curing lamp box 9. The third support 8 is fixed on the upper end surface of the frame 1, and the UV curing lamp box 9 is arranged in the third support 8. The UV curing lamp box 9 includes a lamp shade 91, a cooling assembly 92 and a light-emitting assembly 93 arranged in the lamp shade 91 from top to bottom, a bottom plate 95 located directly below the lamp shade 91, and an opening and closing assembly 94. One end of the bottom plate 95 is hinged to the lamp shade 91 and forms a curing chamber A for placing the product to be cured. The light-emitting assembly 93 is located directly above the curing chamber A. At least one heat insulation plate 96 is arranged in the lamp shade 91, and the heat insulation plate 96 and the inner surface of the lamp shade 91 form an air gap B. The UV curing lamp box 9 further includes guide grooves 97 fixed on the left and right sides of the bottom plate 95 respectively, and the horizontally arranged guide grooves 97 are in communication with the curing chamber A. A heat dissipation plate 8 is arranged directly below the bottom plate 5, and the heat dissipation plate 8 is provided with a plurality of heat dissipation holes. The arrangement of the heat dissipation plate 8 can better dissipate heat from the bottom plate 5. The guide groove 7 is used to place the product to be cured, and the product to be cured is conveyed from one side of the guide groove 7 to the curing chamber D. The cured product is conveyed out through the other side of the guide groove 7.

[0024] Preferably, the upper end of the conveying roller 6 and the upper end of the guide rod 11 are at the same height as the curing chamber A. This helps to reduce the friction of the printing support during the conveying process, improves the conveying efficiency of the printing support, and allows part of the printing support in the curing chamber A to remain in a horizontal state, thereby making the curing effect more uniform.

[0025] The cooling assembly 92 comprises a wind cooling plate 921, an air inlet pipe 922 and an air outlet pipe 923. The wind cooling plate 921 is horizontally arranged in the lampshade 91 and forms an air outlet chamber D with the top wall of the lampshade 91. The air outlet pipe D is arranged at the front end of the lampshade 91 and communicates with the air outlet chamber D. The wind cooling plate 921 forms an air inlet chamber C with the bottom wall of the lampshade 91. The air inlet pipe 922 is arranged at the front end of the lampshade 91 and communicates with the air inlet chamber C. The air outlet chamber D communicates with the air inlet chamber C. The light emitting assembly 93 is fixed below the wind cooling plate 921. The air inlet pipe 922 is connected with an electric heating fan. Hot air is sent to the air inlet chamber C and then flows to the curing chamber A to act on the product to be cured. After the hot air is used, it continues to flow to the air outlet chamber D. The fan connected with the air outlet pipe 923 sucks the hot air out, quickly reduces the accumulation of hot air in the lampshade 91, and avoids that the temperature of the lampshade 91 is too high.

[0026] The light emitting assembly 93 fixed in the air inlet chamber C comprises a lamp tube 931, a lamp holder 932 and a reflector 933. The lamp holder 932 is fixed below the wind cooling plate 921. The reflector 933 and the lamp tube 931 are sequentially fixed in the lamp holder 932 from top to bottom and are arranged downward. The lamp holder 932 is used for better gathering of light of the lampshade 91 and acting on the product to be cured in the curing chamber A, shortening the curing time of the product and improving the curing efficiency.

[0027] The opening and closing assembly 94 comprises a handle 941 and a buckle 942. The rear end of the lampshade 91 is connected with the bottom plate 95 through the buckle 942. The handle 941 is arranged at the rear end of the lampshade 91. When the UV curing lamp box 9 needs to be opened, the handle 941 is pulled upward to open the lampshade 91, the light emitting assembly 93 and the cooling assembly 92 are collectively turned upward, which is convenient for disassembling and repairing the internal parts.

[0028] Optionally, the guide rod 11 is fixed to the second bracket 10. The guide rod 11 is fixed to the second bracket 10 and is conveyed by the conveying roller 6. The print substrate generates a backward friction force relative to the stationary guide rod 11, so that the print substrate is tensioned. The print substrate is conveyed on the stationary guide rod 11, which generates a friction force, so that the conveying resistance of the print substrate is greater. However, the structure is simple and easy to operate, and the cost can be better reduced. Optionally, the guide rod 11 is rotatably arranged on the second bracket 10. A driving motor is installed on the guide rod 11, so that the guide rod 11 can rotate. When the rotating speed of the guide rod 11 and the rotating speed of the conveying roller 6 are different, the conveying direction of the print substrate is adjusted, and the print substrate is conveyed from the end with a slow rotating speed to the end with a fast rotating speed. The print substrate at both ends is also in a tensioned state. The print substrate is conveyed on the rotatable guide rod 11. The guide rod 11 not only can guide, but also can reduce the conveying resistance. However, the rotatable guide rod 11 needs to be provided with bearings at both ends, which increases the production cost.

[0029] Preferably, the base of the housing 1 is provided with four wheels 14. The wheels 14 are provided at the lower end of the housing 1 to facilitate the user in moving the product to different locations.
