Description

Technical Field

[0001] This application relates to the field of printing press equipment processing technology, and in particular to a UV lamp drying device. Background Technology

[0002] In printing operations, the inks used after printing need to be quickly cured and dried by a drying device to ensure the quality, durability, and smooth progress of subsequent processing of the printed materials.

[0003] Currently, common drying technologies use UV lamp drying devices. Existing UV lamp drying devices typically include a chamber with an opening for the printed material to pass through. A UV lamp is installed inside the chamber. When the printed material enters the chamber through the opening, the ultraviolet light generated by the UV lamp radiates onto the surface of the printed material, causing the photosensitive components in the ink to undergo a rapid photochemical reaction within seconds, forming a cross-linked and cured structure. This gives the printed material good abrasion resistance, corrosion resistance, and gloss, ensuring that the colors are long-lasting and vibrant, and that the text and patterns are clear and firmly adhered.

[0004] However, UV lamps not only produce ultraviolet light during operation, but also typically generate infrared light. This infrared light production causes the internal temperature of the UV lamp to rise, and the accumulation of heat leads to an overall increase in the internal temperature of the lamp, reducing its lifespan. Furthermore, printed materials in high-temperature environments may deform due to overheating, resulting in a decrease in print quality and significant drawbacks. Utility Model Content

[0005] In order to improve the lifespan of UV lamps and the quality of printed products, this application provides a UV lamp drying device.

[0006] The UV lamp drying device provided in this application adopts the following technical solution:

[0007] A UV lamp drying device includes a housing with openings on opposite sides for printed materials to pass through. A lampshade is installed inside the housing, and a lamp plate is installed at the bottom of the lampshade. The lamp plate and the inner wall of the lampshade form a hot cavity. A UV lamp is installed inside the hot cavity. An air-cooling assembly is installed inside the housing, including a cold air fan installed at the top of the housing. The air outlet of the cold air fan is connected to the hot cavity via a ventilation duct. Multiple air outlets are provided on the lamp plate for air discharge.

[0008] By adopting the above technical solution, the ultraviolet rays generated by the UV lamp act on the printed matter through the lamp plate. Under the constraint of the lamp cover and the lamp plate, a large amount of heat generated by the UV lamp is accumulated inside the hot chamber. After the cold air fan is started, it draws in and pressurizes the outside cold air, and delivers it to the inside of the hot chamber through the ventilation duct. After the cold air enters the hot chamber, it comes into full contact with the heated UV lamp and absorbs the heat accumulated by the infrared light generated by the UV lamp. The heated air diffuses into the inside of the chamber through the air outlet on the lamp plate, thus forming a complete air-cooling channel. During air circulation, the heat emitted by the UV lamp is carried out to the outside of the lamp cover and the chamber, reducing the possibility of shortening the life of the UV lamp and reducing the quality of the printed matter due to excessively high internal temperature of the chamber.

[0009] Optionally, the ventilation duct includes a main air duct connected to the air outlet pipe of the air cooler, and multiple branch air ducts are connected to the main air duct. The multiple branch air ducts are evenly and equidistantly arranged along the length of the main air duct. The lampshade is connected to a connecting pipe that corresponds to each of the multiple branch air ducts. One end of the connecting pipe is connected to the hot cavity, and the other end is connected to the corresponding branch air duct.

[0010] By adopting the above technical solution, the cold air generated by the air cooler is collected through the main air duct and then distributed through multiple evenly spaced distribution pipes. The air then enters the hot cavity through the connecting pipes that correspond to the distribution pipes. This allows the cold air to enter all areas of the hot cavity evenly, ensuring that all parts of the UV lamp in the hot cavity are fully cooled and reducing the possibility of local overheating or overcooling.

[0011] Optionally, the inner wall of the lampshade has an annular cavity, and a water-cooling assembly is disposed inside the annular cavity. The water-cooling assembly includes a water-cooling coil wound inside the annular cavity. The opposite end faces of the water-cooling coil abut against the opposite inner walls of the annular cavity. A coolant tank is disposed on the housing, and an inlet pipe and a return pipe are connected to the coolant tank. A circulation pump is disposed on the inlet pipe, and the inlet pipe and the return pipe are connected to the water-cooling coil.

[0012] By adopting the above technical solution, when the UV lamp is working, the circulation pump is started, and the coolant flows from the coolant tank into the water-cooling coil through the inlet pipe. As the coolant flows inside the water-cooling coil, it absorbs the heat generated by the UV lamp inside the hot chamber. The heated coolant then flows back to the coolant tank through the return pipe to dissipate heat, thus forming a circulating water-cooling channel. Combined with the air-cooling components, this further improves the heat dissipation effect on the hot chamber and reduces the possibility of heat being transferred from inside the hot chamber to the inside of the chamber, thereby further improving the heat dissipation effect on the UV lamp.

[0013] Optionally, each of the connecting pipes is detachably connected to the corresponding air distribution pipe via a connecting flange. One end of the water-cooled coil is detachably connected to the water inlet pipe via a liquid inlet connector, and the other end is detachably connected to the water return pipe via a liquid outlet connector. The lampshade is detachably connected to the inside of the housing via a connecting assembly. An inspection door is hinged to the outer surface of the housing.

[0014] By adopting the above technical solution, when the UV lamp needs maintenance or the internal components of the lamp cover malfunction, the worker first opens the maintenance door, then removes the connecting flange between the connecting pipe and the air distribution pipe, and separates the inlet and outlet water pipes from the water cooling coil through the liquid inlet and outlet connectors. Finally, the lamp cover and UV lamp are removed as an independent module through the connecting assembly. This achieves a detachable connection between the lamp cover and UV lamp inside the box, which facilitates the worker's maintenance and replacement of damaged parts and improves the convenience of worker operation.

[0015] Optionally, the connecting assembly includes connecting blocks disposed on opposite sides of the lampshade, a guide groove is provided on the inner side wall of the housing to slide with the connecting blocks, a receiving groove is provided inside the connecting blocks, a plug-in post is slidably connected in the receiving groove, a plug-in groove is provided on the inner side wall of the guide groove to plug into the plug-in post, a retaining spring is provided in the receiving groove, the elastic force of the retaining spring drives the plug-in post to insert into the plug-in groove, and a driving member is provided on the lampshade to drive the plug-in post to retract into the receiving groove.

[0016] By adopting the above technical solution, when installing the lampshade, the worker first uses the driving component to retract the plug into the receiving groove, then aligns the connecting block with the guide groove and inserts it. When the connecting block moves to the end of the guide groove, the driving component is canceled, and the spring is tightened to drive the plug into the plug groove, forming a locking structure, which fixes the lampshade inside the housing. Finally, the worker connects the air-cooled component and the water-cooled component to the lampshade.

[0017] When the lamp cover needs to be disassembled for maintenance, the drive unit drives the plug to disengage from the plug slot and retract into the receiving slot. With the sliding guidance of the guide slot, the worker can pull the lamp cover out of the housing, achieving quick disassembly of the lamp cover.

[0018] Optionally, the driving component is a pull rope, one end of which extends into the receiving groove and is disposed on the plug post, and the other end is provided with a pull ring. The lampshade is provided with a hook that engages with the pull ring. When the pull ring is hooked on the hook, the pull rope pulls the plug post to extend into the receiving groove.

[0019] By adopting the above technical solution, when disassembling the lampshade, the worker only needs to pull the pull ring to hook it onto the hook. At this time, the pull rope overcomes the elasticity of the clamping spring and pulls the plug-in post back into the receiving groove, releasing the locking relationship between the plug-in post and the plug-in groove. When installing the lampshade, remove the pull ring on the hook, and the clamping spring automatically pushes the plug-in post to pop out and insert into the plug-in groove, completing the stable installation of the lampshade. The setting of the driving component further simplifies the lampshade disassembly and assembly process and improves the convenience of worker operation.

[0020] Optionally, a handle is provided on the outer surface of the lampshade.

[0021] By adopting the above technical solution, when disassembling the lampshade, workers can more easily pull the lampshade out of the box along the guide groove by holding the handle and using the support and force points of the handle.

[0022] Optionally, the access door may be made of a transparent material.

[0023] By adopting the above technical solution, workers can directly observe the working status of the UV lamps and the operation of the air-cooled and water-cooled components through the inspection door, which facilitates taking measures to repair and handle the problem in advance and avoids the escalation of equipment failure.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application, by setting up air-cooling and water-cooling components, achieves heat dissipation of the UV lamp through the synergistic effect of the air-cooling and water-cooling components during the operation of the UV lamp, thereby reducing the possibility of shortening the life of the UV lamp and reducing the quality of printed materials due to excessive internal temperature of the cabinet.

[0026] 2. This application, by setting up connecting components, driving components, connecting flanges, liquid inlet connectors, and liquid outlet connectors, allows workers to first open the maintenance door when the UV lamp needs maintenance or when internal components of the lamp cover malfunction. Then, the connecting flange between the connecting pipe and the air distribution pipe is removed, and the inlet and outlet water pipes are separated from the water-cooling coil via the liquid inlet and outlet connectors. Finally, the lamp cover and UV lamp are removed as an independent module using the connecting components. This achieves a detachable connection between the lamp cover and UV lamp inside the housing, facilitating maintenance and replacement of damaged components and improving the ease of operation for workers.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a UV lamp 24 drying device.

[0035] Reference Figure 1 and Figure 2 A UV lamp 24 drying device includes a housing 1. The housing 1 has openings 101 on opposite sides for printed materials to pass through. A lampshade 2 is installed on the housing 1. A handle 21 for easy gripping by workers is fixedly connected to the outer surface of the lampshade 2. A light-transmitting plate 22 is installed at the bottom of the lampshade 2. The light-transmitting plate 22 and the inner wall of the lampshade 2 form a heat cavity 23. A UV lamp 24 is installed inside the heat cavity 23. The ultraviolet rays generated by the UV lamp 24 act on the printed materials entering the housing 1 to dry the printed materials.

[0036] Reference Figure 1 and Figure 2 The housing 1 is equipped with an air-cooled component 3 and a water-cooled component 4. Under the constraints of the lamp cover 2 and the lamp plate 22, a large amount of heat generated by the UV lamp 24 is stored inside the hot cavity 23. The air-cooled component 3 and the water-cooled component 4 achieve dual heat dissipation for the UV lamp 24.

[0037] Reference Figure 1 and Figure 2The air-cooled assembly 3 includes a cooler 31 fixedly installed on the top of the housing 1. The cooler 31 is connected to the hot chamber 23 through a ventilation duct. Specifically, the ventilation duct includes a main air duct 32 connected to the air outlet of the cooler 31. Multiple branch air ducts 33 are connected and installed on the main air duct 32. The multiple branch air ducts 33 are evenly spaced along the length of the main air duct 32. The upper surface of the lamp cover 2 is connected and installed with connecting pipes 34 corresponding to the multiple branch air ducts 33. One end of the connecting pipe 34 is connected to the hot chamber 23, and the other end is connected to the corresponding branch air duct 33 through a connecting flange 35. Multiple air outlets 221 for air outlet are opened on opposite sides of the lamp panel 22 along the length.

[0038] After the air cooler 31 is started, it draws outside cold air into the main air duct 32, which then distributes the air through multiple evenly arranged distribution pipes 33 and enters the hot chamber 23 through the connecting pipe 34. This allows the cold air to enter all areas of the hot chamber 23 evenly. After entering the hot chamber 23, the cold air comes into full contact with the heated UV lamp 24 and absorbs the heat accumulated by the infrared light generated by the UV lamp 24. The heated air diffuses into the cabinet 1 through the air outlet 221 on the lamp plate 22, thus forming a complete air-cooling channel. During air circulation, the heat emitted by the UV lamp 24 is carried out to the outside of the lamp cover 2 and the cabinet 1, reducing the possibility of shortening the life of the UV lamp 24 and reducing the quality of printed products due to excessively high internal temperature of the cabinet 1.

[0039] Reference Figure 2 and Figure 3 The inner circumferential sidewall of the lampshade 2 is provided with an annular cavity 25. The water-cooling assembly 4 includes a water-cooling coil 41 wound inside the annular cavity 25. The water-cooling coil 41 is serpentine. The opposite end faces of the water-cooling coil 41 respectively abut against the opposite inner sidewalls of the annular cavity 25. A coolant tank 42 is fixedly installed on the top of the housing 1. A water inlet pipe 43 and a water return pipe 44 are connected and installed on the coolant tank 42. A circulation pump 45 is installed on the water inlet pipe 43. The water inlet pipe 43 is connected to the water inlet of the water-cooling coil 41 through the liquid inlet connector 411. The water return pipe 44 is connected to the liquid outlet of the water-cooling coil 41 through the liquid outlet connector 412.

[0040] Simultaneously with the start of the air cooler 31, the circulation pump 45 is activated. Coolant flows from the coolant tank 42 into the water-cooling coil 41 through the inlet pipe 43. As the coolant flows inside the water-cooling coil 41, it absorbs the heat generated by the UV lamp 24 inside the hot cavity 23. The heated coolant then flows back to the coolant tank 42 through the return pipe 44 to dissipate heat, thus forming a circulating water-cooling channel. Combined with the air-cooling component 3, this further improves the heat dissipation effect on the hot cavity 23 and reduces the possibility of heat being transferred from the hot cavity 23 to the housing 1, thereby further improving the heat dissipation effect on the UV lamp 24.

[0041] Reference Figure 1 and Figure 3To facilitate the maintenance of the lamp cover 2 and UV lamp 24, the lamp cover 2 is detachably connected to the inside of the housing 1 via the connecting assembly 5. The outer surface of the housing 1 is hinged with an inspection door 102, which is made of transparent material so that workers can observe the inside of the housing 1.

[0042] Reference Figure 3 , Figure 4 and Figure 5 The connecting component 5 includes connecting blocks 51 fixedly connected to opposite sides of the lampshade 2. The inner side wall of the housing 1 is provided with a guide groove 6 that slides with the connecting blocks 51. The guide groove 6 is parallel to the width direction of the housing 1. The connecting block 51 is provided with a receiving groove 511 in the vertical direction. A plug-in post 52 is slidably connected in the receiving groove 511. The inner side wall of the guide groove 6 near the end is provided with a plug-in groove 61 that plugs into the plug-in post 52.

[0043] Reference Figure 4 and Figure 5 When the connecting block 51 abuts against the end of the guide groove 6, the axis of the receiving groove 511 and the insertion groove 61 are on the same straight line. A clamping spring 53 is provided in the receiving groove 511. One end of the clamping spring 53 is fixedly connected to the inner side wall of the receiving groove 511, and the other end is fixedly connected to the insertion post 52. The elastic force of the clamping spring 53 drives the insertion post 52 to insert into the insertion groove 61.

[0044] Reference Figure 4 and Figure 5 The lampshade 2 is provided with a driving component corresponding to the plug-in post 52. The driving component is a pull rope 7. One end of the pull rope 7 extends into the receiving groove 511 and is fixedly connected to the plug-in post 52. The other end extends out of the connecting block 51 and is fixedly connected to the pull ring 71. The lampshade 2 is fixedly connected with a hook 72 corresponding to the two pull ropes 7. The hook 72 is hooked and engaged with the corresponding pull ring 71. When the pull ring 71 is hooked on the corresponding hook 72, the pressing spring 53 is in a compressed state. At this time, the pull rope 7 pulls the plug-in post 52 to extend into the receiving groove 511.

[0045] When the internal components of the UV lamp 24 or the lamp cover 2 malfunction and need to be disassembled, the worker opens the inspection door 102, then removes the connecting flange 35 between the connecting pipe 34 and the air distribution pipe 33, and separates the inlet and outlet water pipes 44 from the water cooling coil 41 through the liquid inlet connector 411 and the liquid outlet connector 412. Then the worker pulls the two pull rings 71, and the pull rings 71 pull the two plug pins 52 out of the plug slot 61 and retract into the receiving slot 511 through the pull rope 7. The worker hangs the pull rings 71 on the hook 72 to keep the plug pins 52 in the retracted state. Finally, with the sliding guide of the guide slot 6, the worker holds the handle 21 and pulls the lamp cover 2 out of the box 1 to achieve quick disassembly of the lamp cover 2.

[0046] When installing a fully functional lampshade 2, the worker first hangs the two pull rings 71 on the hook 72. At this time, the plug-in post 52 is inside the receiving groove 511. Then, the connecting block 51 is aligned with the guide groove 6 and inserted. When the connecting block 51 moves to the end of the guide groove 6, the pull rings 71 on the hook 72 are removed. The spring 53 automatically pushes the plug-in post 52 to pop out and insert into the plug-in groove 61, completing the stable installation of the lampshade 2. Finally, the lampshade 2 is connected to the air-cooled assembly and the water-cooled assembly 4. This realizes the detachable connection between the lampshade 2 and the UV lamp 24 inside the housing 1, which makes it easier for workers to maintain and replace damaged parts and improves the convenience of worker operation.

[0047] The implementation principle of the UV lamp 24 drying device in this application embodiment is as follows: When the UV lamp 24 is working, the air cooler 31 and the circulation pump 45 are started. The air cooler 31 draws cold air from the outside into the main air duct 32. After being split by the air distribution pipe 33, the air enters the hot chamber 23 through the connecting pipe 34. The cold air absorbs the heat accumulated by the infrared light generated by the UV lamp 24. The heated air diffuses into the chamber 1 through the air outlet 221 on the lamp plate 22, and then is discharged through the exhaust port on the outer surface of the chamber 1. In this way, a complete air-cooling channel is formed. During air circulation, the heat emitted by the UV lamp 24 is carried out to the outside of the lamp cover 2 and the chamber 1, reducing the possibility of shortening the life of the UV lamp 24 and reducing the quality of printed materials due to excessively high internal temperature of the chamber 1.

[0048] Meanwhile, under the action of the circulating pump 45, the coolant flows from the coolant tank 42 into the water-cooling coil 41 through the inlet pipe 43. As the coolant flows inside the water-cooling coil 41, it absorbs the heat generated by the UV lamp 24 inside the hot cavity 23. The heated coolant then flows back to the coolant tank 42 through the return pipe 44 to dissipate heat, thus forming a circulating water-cooling channel. Combined with the air-cooling component 3, this further improves the heat dissipation effect on the hot cavity 23 and reduces the possibility of heat being transferred from inside the hot cavity 23 to inside the housing 1, thereby further improving the heat dissipation effect on the UV lamp 24.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
