Abstract
Description
Technical Field
[0001] This utility model relates to the field of curing technology, and in particular to a gravure printing curing device. Background Technology
[0002] Gravure curing is a crucial step in the gravure printing process, using a specific curing device to rapidly dry the ink on the surface of the printed material. As the core equipment for this process, the gravure curing device must be coordinated with the speed of the printing production line and the characteristics of the printing materials to ensure uniform and efficient curing. Among various gravure curing technologies, UV curing is widely used due to its advantages such as fast curing speed, low energy consumption, and good environmental friendliness; its core equipment is the UV curing device. This device uses UV lamps to emit ultraviolet light, irradiating the UV ink on the surface of the printed material. This causes the photoinitiator in the ink to be excited, generating free radicals or cations, thus promoting the instantaneous curing of the ink.
[0003] However, UV curing equipment suffers from significant interference from impurities during actual operation. The printing production environment typically contains impurities such as paper fibers, ink particles, and dust, which can easily enter the UV curing equipment along with the printed materials. Since UV lamps generate high temperatures during operation, and components such as reflectors and cooling systems need to be kept clean to ensure UV reflection efficiency and heat dissipation, impurities adhering to these critical components can cause a series of problems: impurities on the UV lamp surface hinder UV transmission, reducing curing energy and resulting in incomplete curing and a sticky surface; when the reflector is covered by impurities, UV reflectivity decreases, further weakening the curing effect, and uneven energy distribution may lead to localized overheating or insufficient curing of the printed material; when the cooling system (such as heat sinks and fans) is blocked by impurities, heat dissipation efficiency decreases, potentially causing UV lamp damage due to overheating, shortening equipment lifespan, and increasing maintenance costs. Therefore, this application proposes a gravure printing curing device to solve the above problems. Utility Model Content
[0004] The main purpose of this invention is to provide a gravure printing curing device that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A gravure printing curing apparatus includes a UV curing device. Two pneumatic drive devices are symmetrically fixedly installed at both ends of the UV curing device. Two dust collection components are symmetrically fixedly installed at both ends of the UV curing device. Two movable dust collection hood assemblies are movably installed at both ends of the UV curing device. The movable dust collection hood assemblies are simultaneously fixedly installed on the pneumatic drive devices and the dust collection components.
[0007] Preferably, the pneumatic drive device consists of a cylinder assembly and a U-shaped mounting bracket. The U-shaped mounting bracket is fixedly installed at the lower end of the piston rod of the cylinder assembly. Two fitting through holes are symmetrically opened on the lower side wall of the U-shaped mounting bracket. The cylinder assembly is fixedly installed at one end of the UV curing device.
[0008] Preferably, the dust collection assembly is located between two adjacent pneumatic drive devices. The dust collection assembly consists of a dust collection device body and a connecting corrugated pipe. The upper part of the connecting corrugated pipe is fixedly inserted into the dust collection device body, and the dust collection device body is fixedly installed at one end of the UV curing device.
[0009] Preferably, the mobile vacuum hood assembly consists of a vacuum hood body and an intercepting protective net. The intercepting protective net is fixedly installed on the lower inner wall of the vacuum hood body, and an insertion through hole is provided on the upper inner wall of the vacuum hood body. The vacuum hood body is fixedly sleeved on the lower part of the connecting corrugated pipe through the insertion through hole.
[0010] Preferably, four mounting screws are symmetrically fixedly installed on the upper end of the vacuum hood body on the mobile vacuum hood assembly.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] By installing pneumatic drive devices, dust collection components, and mobile dust collection hood components at both ends of the UV curing equipment, the main body of the dust collection device can effectively remove impurities such as paper fibers, ink particles, and dust from the printing production environment through the dust collection hood. This prevents these impurities from entering the UV curing equipment and adhering to key components such as UV lamps, reflectors, and cooling systems. This ensures the ultraviolet transmittance of the UV lamps and the reflection efficiency of the reflectors, ensuring sufficient and uniform curing energy. It also prevents problems such as incomplete curing, sticky surfaces, or localized overheating of printed materials. At the same time, it maintains the heat dissipation efficiency of the cooling system, reducing the possibility of UV lamp damage due to overheating, extending the equipment's lifespan, and reducing maintenance costs. The pneumatic drive device can move the mobile dust collection hood component up and down, flexibly adjusting the distance between the dust collection hood and the printed materials to adapt to printing materials of different thicknesses and ensure effective dust collection.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a gravure printing curing apparatus includes a UV curing device 1. Two pneumatic drive devices 2 are symmetrically fixedly installed at both the front and rear ends of the UV curing device 1. Two dust collection components 3 are symmetrically fixedly installed at both the front and rear ends of the UV curing device 1. Two movable dust collection hood assemblies 4 are movably installed at both the front and rear ends of the UV curing device 1. The movable dust collection hood assemblies 4 are simultaneously fixedly installed on the pneumatic drive devices 2 and the dust collection components 3. By setting the pneumatic drive devices 2, dust collection components 3, and movable dust collection hood assemblies 4 at the front and rear ends of the UV curing device 1, the dust collection device body 8 can effectively remove paper fibers, ink particles, dust, etc., from the printing production environment through the dust collection hood body 10. Impurities are removed to prevent them from entering the UV curing equipment 1 and adhering to key components such as the UV lamps, reflectors, and cooling system. This ensures the UV transmittance of the UV lamps and the reflectivity of the reflectors, guaranteeing sufficient and uniform curing energy. This prevents problems such as incomplete curing, sticky surfaces, or localized overheating of printed materials. At the same time, it maintains the heat dissipation efficiency of the cooling system, reducing the risk of UV lamp damage due to overheating, extending the equipment's lifespan, and lowering maintenance costs. The pneumatic drive device 2 can move the mobile dust collection hood assembly 4 up and down, flexibly adjusting the distance between the dust collection hood body 10 and the printed materials to adapt to printing materials of different thicknesses and ensure effective dust collection.
[0020] Specifically, the pneumatic drive device 2 consists of a cylinder assembly 5 and a U-shaped mounting bracket 6. The U-shaped mounting bracket 6 is fixedly installed at the lower end of the piston rod of the cylinder assembly 5. Two fitting through holes 7 are symmetrically opened on the lower side wall of the U-shaped mounting bracket 6. The cylinder assembly 5 is fixedly installed at one end of the UV curing device 1. The dust collection assembly 3 is located between two adjacent pneumatic drive devices 2. The dust collection assembly 3 consists of a dust collection device body 8 and a connecting corrugated pipe 9. The upper part of the connecting corrugated pipe 9 is fixedly inserted into the dust collection device body 8. The dust collection device body 8 is fixedly installed at one end of the UV curing device 1. The movable dust collection hood assembly 4 consists of a dust collection hood body 10 and an intercepting protective net 11. The intercepting protective net 11 is fixedly installed on the lower inner wall of the dust collection hood body 10. An insertion through hole 12 is opened on the upper inner wall of the dust collection hood body 10. The dust hood assembly 4 is fixedly fitted to the lower part of the connecting bellows 9 through the insertion through hole 12. Four mounting screws 13 are symmetrically fixedly installed on the upper end of the dust hood body 10. The four mounting screws 13 are located on both sides of the insertion through hole 12. The dust hood body 10 is tightly attached to the lower end of the U-shaped mounting frame 6. The mounting screws 13 pass upward through the fitting through hole 7. A fixing nut 14 is installed on the mounting screw 13, and the fixing nut 14 is located at the upper end of the lower side wall of the U-shaped mounting frame 6. The UV curing equipment 1 is installed behind the gravure printing equipment. The table surface on which it is installed must be a flat plane. This flat plane can fit tightly with the bottom of the UV curing equipment 1, thereby sealing the bottom of the UV curing equipment 1 and effectively preventing external paper fibers, ink particles, dust and other impurities from entering the equipment from the gaps under the UV curing equipment 1.
[0021] After the UV curing equipment 1 is started, the UV lamps inside emit ultraviolet light. When the gravure printed product is conveyed to the UV curing equipment 1 along with the production line, the ultraviolet light irradiates the ink on the surface of the gravure printed product, causing the photoinitiator in the ink to be excited and generate free radicals or cations, which promotes the ink to cure instantly, completing the curing operation. At this time, the cylinder assembly 5 of the pneumatic drive equipment 2 adjusts the extension and retraction of its piston rod according to the thickness of the gravure printed product, driving the U-shaped mounting frame 6 to move up and down. The U-shaped mounting frame 6 drives the dust collection hood body 10 of the moving dust collection hood assembly 4 to move up and down synchronously through the mounting screw 13 and the fixing nut 14, so as to adjust the distance between the dust collection hood body 10 and the gravure printed product to ensure that it can adapt to products of different thicknesses. At the same time, the main body 8 of the vacuuming assembly 3 is activated, generating suction. The suction is transmitted to the main body 10 of the movable vacuum hood assembly 4 through the connecting corrugated pipe 9. The main body 10 of the vacuum hood begins to remove paper fibers, ink particles, dust and other impurities from the printing production environment. During the process of being sucked in, the impurities first pass through the interception and protection net 11. The interception and protection net 11 initially intercepts larger impurities to prevent them from entering the connecting corrugated pipe 9 and the main body 8 of the vacuuming assembly and causing blockage. Subsequently, impurities that meet the suction conditions enter the main body 8 of the vacuuming assembly through the connecting corrugated pipe 9 and are collected and processed. Throughout the process, the connecting corrugated pipe 9 flexibly extends and retracts with the up and down movement of the main body 10 of the vacuum hood to ensure that the vacuuming function is continuously effective.
[0022] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
