Description

Technical Field

[0001] This utility model relates to the technical field of side-spraying devices, specifically a UV printing side-spraying device. Background Technology

[0002] UV side-printing devices are a technology for printing patterns, text, or logos on the edges or sides of materials. Unlike normal downward-facing printing, its main structure involves placing the printhead base plate on its side, with the bottom of the printhead facing the side of the object, thus achieving side printing. In terms of ink path design, it employs a multi-stage ink path protection and continuous ink supply system to ensure uninterrupted ink printing over large areas and allows for ink refilling without stopping the machine. The environmentally friendly UV ink used is highly adaptable to various materials, providing excellent adhesion and visual effects on both penetrating and non-penetrating surfaces.

[0003] Existing UV printing side-spraying devices are widely used, but the spray plate in existing devices is usually fixed, which may result in uneven spraying. In addition, fixing the spray plate in existing devices is not convenient. Therefore, a UV printing side-spraying device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a UV printing side spraying device to solve the problems of inconvenient fixing of the spray plate and uneven spraying in the existing devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A UV printing side-spraying device includes a spray box and side nozzles symmetrically mounted on the top of the spray box. A base plate is fixedly connected to the outside of each side nozzle and to the top of the spray box. A protective box is fixedly connected to the top of the base plate. A rotary joint is fixedly connected to the center of the top of the base plate inside the protective box. A connecting pipe communicating with the rotary joint is fixedly connected to the outside of the rotary joint. An air pump communicating with the rotary joint is fixedly connected to the end of the connecting pipe away from the rotary joint. An adsorption plate is fixedly connected to the top of the rotary joint. Multiple adsorption holes communicating with the rotary joint are opened on the top of the adsorption plate. A sealing ring is fixedly connected to the top of the adsorption plate outside each adsorption hole. A spray plate is positioned above the sealing ring. A driving assembly is installed at the bottom of the adsorption plate, and a protective assembly is installed outside the driving assembly.

[0007] Preferably, the connecting pipe passes through the base plate and is fixedly connected to the base plate, and the air pump is fixedly connected to the bottom end of the base plate.

[0008] Preferably, the side nozzle is horizontally aligned with the spray plate, and the top of the sealing ring is tightly fitted with the bottom of the spray plate.

[0009] Preferably, the drive assembly includes a first gear fixedly connected to the outer side of the top of the rotary joint, a second gear meshing with the outer side of the first gear, and the output shaft of a rotary motor fixedly connected to the bottom end of the second gear.

[0010] Preferably, the rotating motor is fixedly connected to the bottom end of the base plate, and the output shaft of the rotating motor passes through the base plate and is rotatably connected to the base plate.

[0011] Preferably, the protective component includes a fixing ring fixedly connected to the outside of the adsorption plate, a telescopic tube fixedly connected to the bottom end of the fixing ring, a bottom ring fixedly connected to the bottom end of the telescopic tube, and a spring provided on the outside of the telescopic tube.

[0012] Preferably, the top end of the spring is fixedly connected to the bottom end of the fixed ring, the bottom end of the spring is fixedly connected to the top end of the bottom ring, and the bottom end of the bottom ring is tightly fitted with the top end of the base plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a rotary joint, connecting pipe, air pump, adsorption plate, adsorption hole, sealing ring, spray plate and driving assembly, when using the device, the spray plate is placed on the top of the adsorption plate. At this time, the air pump sucks away the air between the sealing ring and the spray plate, thereby adsorbing and fixing the spray plate. The next step is to start the driving assembly. The rotating motor at the bottom of the base plate rotates and drives the rotary joint, adsorption plate and spray plate to rotate. This design makes it easier to fix the spray plate and allows the spray plate to rotate during spraying, so that the side of the spray plate is sprayed more evenly.

[0015] 2. In this utility model, through the protective components, fixing ring, telescopic tube, bottom ring and spring, when the device is in use, because the spring at the bottom end of the fixing ring always presses the bottom ring to extend the telescopic tube, and makes the bottom end of the bottom ring fit tightly with the top end of the base plate, the telescopic tube can protect the drive component and its connecting components, and prevent ink from entering the inside of the telescopic tube and adhering to the first gear, second gear and other components, causing them to jam.

[0027] Please see Figure 1-7 This utility model provides a technical solution:

[0028] A UV printing side-spray device includes a spray box 1 and side nozzles 2 symmetrically mounted on the top of the spray box 1. A base plate 3 is fixedly connected to the outside of the side nozzles 2 and to the top of the spray box 1. A protective box 4 is fixedly connected to the top of the base plate 3. A rotary joint 5 is fixedly connected to the center of the top of the base plate 3 inside the protective box 4. A connecting pipe 6, communicating with the rotary joint 5, is fixedly connected to the outside of the rotary joint 5. An air pump 7, communicating with the rotary joint 5, is fixedly connected to the end of the connecting pipe 6 away from the rotary joint 5. An adsorption plate 8 is fixedly connected to the top of the rotary joint 5. Multiple adsorption holes 9, communicating with the rotary joint 5, are opened on the top of the adsorption plate 8. A sealing ring 10, fixedly connected to the top of the adsorption plate 8, is provided outside the adsorption holes 9. A spray plate 11 is positioned above the sealing ring 10. A driving assembly 12 is installed at the bottom of the adsorption plate 8. A protective assembly 13 is installed outside the driving assembly 12. The connecting pipe 6 passes through the base plate 3 and is fixedly connected to it. The air pump 7 is fixedly connected to the bottom of the base plate 3. The side nozzles 2 and the spray plate 11 are horizontally aligned. The top of the sealing ring 10 is aligned with the spray plate 11. The bottom end fits tightly. The drive assembly 12 includes a first gear 121 fixedly connected to the outer side of the top of the rotary joint 5. A second gear 122 is meshed with the outer side of the first gear 121. The output shaft of the rotary motor 123 is fixedly connected to the bottom end of the second gear 122. The rotary motor 123 is fixedly connected to the bottom end of the base plate 3. The output shaft of the rotary motor 123 passes through the base plate 3 and is rotatably connected to the base plate 3. Through the provided rotary joint 5, connecting pipe 6, air pump 7, adsorption plate 8, adsorption hole 9, sealing ring 10, spray plate 11 and drive assembly 12, when using the device, the spray plate 11 is placed on the top of the adsorption plate 8. At this time, the air pump 7 sucks away the air between the sealing ring 10 and the spray plate 11, thereby adsorbing and fixing the spray plate 11. Next, the drive assembly 12 is started. The rotary motor 123 at the bottom end of the base plate 3 rotates, driving the rotary joint 5, adsorption plate 8 and spray plate 11 to rotate. This design makes it easier to fix the spray plate 11 and allows the spray plate 11 to rotate during spraying, making the side of the spray plate 11 more evenly sprayed.

[0029] The protective component 13 includes a fixed ring 131 fixedly connected to the outside of the adsorption plate 8. A telescopic tube 132 is fixedly connected to the bottom end of the fixed ring 131. A bottom ring 133 is fixedly connected to the bottom end of the telescopic tube 132. A spring 134 is provided on the outside of the telescopic tube 132. The top end of the spring 134 is fixedly connected to the bottom end of the fixed ring 131. The bottom end of the spring 134 is fixedly connected to the top end of the bottom ring 133. The bottom end of the bottom ring 133 is tightly fitted to the top end of the base plate 3. Through the protective component 13, the fixed ring 131, the telescopic tube 132, the bottom ring 133, and the spring 134, when the device is in use, the spring 134 at the bottom end of the fixed ring 131 always presses the bottom ring 133, causing the telescopic tube 132 to extend and the bottom end of the bottom ring 133 to be tightly fitted to the top end of the base plate 3. The telescopic tube 132 can thus protect the drive component 12 and its connecting components, preventing ink from entering the inside of the telescopic tube 132 and adhering to components such as the first gear 121 and the second gear 122, causing them to jam.

[0030] Workflow: Before use, power on the equipment and connect it to the external controller. When using the equipment, first start the air pump 7 and open the protective box 4. Place the spray plate 11 on top of the adsorption plate 8. At this time, the air pump 7 sucks away the air between the sealing ring 10 and the spray plate 11 through the connecting pipe 6, rotary joint 5, and adsorption hole 9, creating a negative pressure environment between the spray plate 11 and the adsorption plate 8, thereby adsorbing and fixing the spray plate 11. Next, start the drive assembly 12. The rotating motor 123 at the bottom of the base plate 3 rotates, driving the second gear 122 to rotate. Since the first gear 121 and the second gear 122 are meshed, the first gear 121 drives the rotary joint 5, adsorption plate 8, and spray plate 11 to rotate. At this time, the spray box 1 can be started, and the side nozzle 2 sprays ink onto the side of the spray plate 11. The spray plate 11 rotates slowly to spray ink. The coating is evenly applied. At the same time, the spring 134 at the bottom of the fixing ring 131 always presses the bottom ring 133, causing the telescopic tube 132 to extend and the bottom end of the bottom ring 133 to fit tightly against the top of the base plate 3. The telescopic tube 132 can thus protect the drive assembly 12 and its connecting components, preventing ink from entering the inside of the telescopic tube 132. After the spraying is completed, the air pump 7 and the rotating motor 123 can be turned off, and the protective box 4 can be opened to take out the spray plate 11. The design of the drive assembly 12 and its connecting components makes it easier to fix the spray plate 11 and allows the spray plate 11 to rotate during spraying, making the side of the spray plate 11 sprayed more evenly. The design of the protective component 13 can protect the drive assembly 12 and its connecting components, preventing ink from adhering to components such as the first gear 121 and the second gear 122, causing them to jam.
