Description

Technical Field

[0001] The present invention relates to the technical field of packaging box processing, and particularly to a quick-drying device for UV ink printing of packaging boxes. Background Art

[0002] As the name implies, a packaging box is a box used to package products. It can be classified by materials, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. It can also be classified by the names of products, such as mooncake boxes, tea boxes, wolfberry boxes, candy boxes, delicate gift boxes, local specialty boxes, wine boxes, chocolate boxes, food, medicine, and health product boxes, food packaging boxes, tea packaging boxes, stationery boxes, etc. The functions of packaging boxes are to ensure the safety of products during transportation and improve the grade of products. With the rapid development of modern industry and the continuous improvement of people's living standards, the demand for packaging boxes will continue to increase, and higher requirements are also put forward for the quality of iron boxes. The increase in short-run jobs, the improvement of processing quality, and the reduction of production costs are also the market pressures and problems faced by paper box packaging enterprises. This requires the application of new technologies in the production process of iron box packaging to continuously improve the automation level of equipment, reduce the adjustment time of equipment and the auxiliary preparation time of jobs. Only by continuously adapting to the new changes in the market and meeting the requirements of different users can the competitiveness of packaging box packaging enterprises be improved.

[0003] After the existing packaging boxes are produced, decorative patterns are usually printed on the surface of the packaging boxes to keep them beautiful. Usually, UV ink is used for printing. After printing with UV ink, it is necessary to wait until the UV ink is completely dry before proceeding to the next step of processing to avoid damage to the patterns. Currently, it is usually to wait for the UV ink to cool naturally, which takes a long time and wastes a lot of time, greatly reducing the processing efficiency of the packaging boxes.

[0004] Based on this, we propose a quick-drying device for UV ink printing of packaging boxes. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Referring to Figures 1-4 , a quick-drying device for UV ink printing on a packaging box, comprising a base 1, a plurality of support rods 101 fixedly connected to the upper end of the base 1, and a drying box 2 fixedly connected to the upper ends of the plurality of support rods 101;

[0028] A drying mechanism, the drying mechanism includes a chute 3, a drying plate 4, an annular cavity 5, air spray holes 6, a vortex tube 7, a high-pressure inlet pipe 8, a hot air pipe 9, and a driving assembly. Two chutes 3 are symmetrically formed in the inner wall of the drying box 2, and a drying plate 4 is slidably connected to the inner walls of the two chutes 3. An annular cavity 5 is formed in the drying plate 4, and a plurality of air spray holes 6 are formed in the inner wall of the annular cavity 5. A vortex tube 7 is fixedly connected to the upper end of the drying box 2, a high-pressure inlet pipe 8 is fixedly connected to the upper end of the vortex tube 7, and the vortex tube 7 is communicated with the annular cavity 5 through a hot air pipe 9. The hot air pipe 9 is made of a high-temperature resistant flexible hose;

[0029] It should be noted that the aperture of the air spray holes 6 becomes smaller from left to right, and the arrangement density also becomes smaller. Thus, in the early stage, the UV ink has large fluidity and the hot air flow rate and velocity are small, avoiding blowing the UV ink to flow and causing pattern damage. In the later stage, the UV ink dries up, and the hot air flow rate and velocity are large, which can improve the drying efficiency.

[0030] A conveying mechanism, the conveying mechanism includes vertical plates 10, a rotating shaft 11, conveying rollers 12, and a conveyor belt 13. Four vertical plates 10 are fixedly connected to the upper end of the base 1. The side walls of two vertical plates 10 on the same side that are close to each other are rotatably connected to a rotating shaft 11, and a conveying roller 12 is fixedly connected to the side wall of the rotating shaft 11. The conveying rollers 12 are connected by a conveyor belt 13.

[0031] Further, place the printed packaging box on the conveyor belt 13, drive the motor 17 to rotate clockwise, drive the rotating shaft 11 to rotate, drive the conveyor roller 12 to rotate clockwise, so that the conveyor belt 13 conveys the packaging box to the right. The packaging box will enter the drying box 2 through the frame opening 28, and then pump general compressed air into the vortex tube 7 through the high-pressure air inlet pipe 8. After being converted by the vortex tube 7, the hot air will enter the annular cavity 5 through the hot air pipe 9, and then the hot air will be ejected from multiple air spray holes 6 to quickly dry the UV ink on the upper end of the packaging box, without long waiting, greatly improving the processing efficiency of the packaging box, and being able to continuously dry a large number of packaging boxes in batches, with higher efficiency.

[0032] Cooling mechanism, the cooling mechanism includes a cooling plate 14, an air inlet cavity 15, air outlet holes 16 and a cold air pipe 161. The side wall of the drying box 2 is fixedly connected with the cooling plate 14. An air inlet cavity 15 is opened in the cooling plate 14. A plurality of air outlet holes 16 are opened on the inner wall of the air inlet cavity 15. The vortex tube 7 is communicated with the air inlet cavity 15 through the cold air pipe 161.

[0033] Further, the dried packaging box will move out of the drying box 2 through another frame opening 28. When it moves below the cooling plate 14, the cold air generated by the vortex tube 7 will enter the air inlet cavity 15 through the cold air pipe 161, and then the cold air will be ejected from the multiple air outlet holes 16, which can quickly cool the dried packaging box and facilitate the packaging box to quickly enter the next processing step.

[0034] The driving assembly includes a motor 17 fixedly connected to the upper end of the base 1 through a bracket. The output end of the motor 17 is fixedly connected with a first one-way bearing 18. The other end of the first one-way bearing 18 is fixedly connected with a second one-way bearing 19. One end of the rotating shaft 11 penetrates through the side wall of the vertical plate 10 and is fixedly connected with the second one-way bearing 19.

[0035] The driving assembly further includes a reciprocating lead screw 20 rotatably connected to the inner top of the drying box 2. The side wall of the reciprocating lead screw 20 is threadedly connected with the drying plate 4. An installation cavity 21 is opened in the upper end of the drying box 2. A rotating rod 22 is rotatably connected to the inner wall of the installation cavity 21. A first bevel gear 23 is fixedly connected to the side wall of the rotating rod 22. The upper end of the reciprocating lead screw 20 extends into the installation cavity 21 and is fixedly connected with a second bevel gear 24. The first bevel gear 23 is meshed with the second bevel gear 24. A driving wheel 25 is fixedly connected to the side wall of the first one-way bearing 18. One end of the rotating rod 22 penetrates through the side wall of the drying box 2 and is fixedly connected with a driven wheel 26. The driving wheel 25 is connected with the driven wheel 26 through a synchronous belt.

[0036] It should be noted that the first one-way bearing 18 and the second one-way bearing 19 are arranged in opposite directions. The output end of the motor 17 is fixedly connected to the inner ring of the first one-way bearing 18. The outer ring of the second one-way bearing 19 is fixedly connected to the inner ring of the first one-way bearing 18. The rotating shaft 11 is fixedly connected to the inner ring of the second one-way bearing 19. When the motor 17 rotates counterclockwise, the driving wheel 25 can be driven to rotate through the first one-way bearing 18, while the rotating shaft 11 does not rotate at this time. When the motor 17 rotates clockwise, the rotating shaft 11 can be driven to rotate through the first one-way bearing 18 and the second one-way bearing 19, while the driving wheel 25 does not rotate at this time.

[0037] Furthermore, when adjusting the height of the drying plate 4, by driving the motor 17 to rotate counterclockwise, the motor 17 can drive the driving wheel 25 to rotate through the first one-way bearing 18, drive the driven wheel 26 to rotate, and then drive the rotating rod 22 to rotate, drive the first bevel gear 23 to rotate, drive the second bevel gear 24 to rotate, and then drive the reciprocating lead screw 20 to rotate, driving the drying plate 4 to move up or down to adjust the height of the drying plate 4, so as to adjust the drying plate 4 to a suitable height, which is convenient to adjust the height of the drying plate 4 according to the depth of the printed pattern. The ink of the light-colored pattern is less, and the height of the drying plate 4 can be higher. The ink of the dark-colored pattern is more, and the height of the drying plate 4 can be lower, thereby avoiding uneven drying of the ink.

[0038] Both inner walls of the two sliding grooves 3 are fixedly connected with sliding rods 27, and the side walls of the sliding rods 27 are slidably connected to the drying plate 4.

[0039] Two frame openings 28 are symmetrically formed on the side wall of the drying box 2. The conveyor belt 13 is arranged to penetrate through the two frame openings 28, and a plurality of sealing strips 29 adapted to the frame openings 28 are fixedly connected to the inner wall of the drying box 2. The sealing strips 29 are made of flexible materials.

[0040] In the present invention, first, the height of the drying plate 4 is adjusted. By driving the motor 17 to rotate counterclockwise, the motor 17 can drive the driving wheel 25 to rotate through the first one-way bearing 18, drive the driven wheel 26 to rotate, and then drive the rotating rod 22 to rotate, drive the first bevel gear 23 to rotate, drive the second bevel gear 24 to rotate, and then drive the reciprocating lead screw 20 to rotate, driving the drying plate 4 to move up or down to adjust the height of the drying plate 4, so as to adjust the drying plate 4 to a suitable height.

[0041] Next, place the printed packaging box on the conveyor belt 13. The drive motor 17 rotates clockwise, driving the rotating shaft 11 to rotate, driving the conveyor roller 12 to rotate clockwise, and thus the conveyor belt 13 conveys the packaging box to the right. The packaging box will enter the drying box 2 through the frame opening 28. Then, common compressed air is pumped into the vortex tube 7 through the high-pressure air inlet pipe 8. After being converted by the vortex tube 7, the hot air will enter the annular cavity 5 through the hot air pipe 9, and then the hot air will be ejected from multiple air nozzles 6 to quickly dry the UV ink on the upper end of the packaging box.

[0042] The dried packaging box will move out of the drying box 2 through another frame opening 28. When it moves below the cooling plate 14, the cold air generated by the vortex tube 7 will enter the air inlet cavity 15 through the cold air pipe 161, and then the cold air will be ejected from multiple air outlet holes 16, which can quickly cool the dried packaging box and facilitate the packaging box to quickly enter the next processing step.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
