Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and in particular relates to a reflector structure for a banknote printing lamp. Background Technology

[0002] The reflector of a banknote printing lamp is an important component of printing equipment, typically used in banknote printing machines or other similar devices. It ensures uniform light distribution and enhances the focusing effect of the light source. Its main function is to effectively guide the light to the required area, improving the efficiency and quality of lighting and avoiding light waste. Through the principles of reflection and refraction, the reflector optimizes the light output of the lamp, ensuring that the entire working area is adequately illuminated. Especially when performing fine printing or pattern recognition, it can guarantee higher accuracy and clarity.

[0003] Existing reflectors for banknote printing lamps still present several problems during use. For example, traditional reflectors employ a single curvature design, resulting in low light reflectivity and uneven ink curing, affecting printing quality and efficiency. Furthermore, the thickness design of traditional reflectors is often inadequate, making them prone to deformation at high temperatures and impacting printing accuracy. Therefore, we provide a reflector structure for banknote printing lamps to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a reflector structure for a banknote printing lamp. By combining efficiency-enhancing components and protective components, it solves the problems of low light reflectivity and easy deformation of the reflector due to high temperature in the existing banknote printing lamp reflector, which affects printing accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a reflector structure for a banknote printing lamp, including a mounting frame, with a cover body fixedly connected to one side of the mounting frame; an efficiency-enhancing component is provided on the surface of the cover body, comprising a main reflective area on one side of the cover body surface, a micro-reflective area on the other side of the cover body surface, and a compensation reflective area on one side of the mounting frame surface, thereby improving the reflectivity of the banknote printing lamp light; a protective component is provided on the surface of the mounting frame, comprising a connecting flange layer fixedly connected to the surface of the mounting frame, a reinforcing layer fixedly connected to one side of the cover body, and a main body layer fixedly connected to the surface of the cover body, thereby preventing the cover body from deforming due to high temperature.

[0007] The present invention is further configured such that a positioning hole is provided on one side of the inner cavity of the cover, and an installation hole is provided on one side of the inner cavity of the mounting bracket.

[0008] The present invention is further configured such that the surface of the cover is coated with a high reflectivity coating, and the surface roughness Ra of the high reflectivity coating is ≤0.8μm.

[0009] The present invention is further configured such that the flatness of the connecting flange layer is ≤0.05mm and the coefficient of thermal expansion is 8.6×10⁻⁶. -6 / ℃.

[0010] The present invention is further configured such that the material of the cover is a honeycomb reinforcing rib, and the inner cavity of the honeycomb reinforcing rib is provided with an array of heat dissipation holes.

[0011] The present invention has the following beneficial effects.

[0012] 1. This utility model, by setting up efficiency-enhancing components, significantly improves the reflectivity of the banknote printing lamp light through the synergistic effect of the main reflective area, micro reflective area, and compensating reflective area. This ensures that the light uniformly covers the entire printing area. The main reflective area is responsible for large-area light reflection, the micro reflective area further optimizes the light distribution through a fine reflective surface design, and the compensating reflective area fills the light gap between the main reflective area and the micro reflective area, ensuring that the light uniformly covers the entire printing area. This not only improves the light utilization efficiency but also makes the ink curing more uniform, thereby improving printing quality and efficiency.

[0013] 2. This utility model effectively prevents the reflector from deforming due to high temperatures by setting up protective components, including a connecting flange layer, a reinforcing layer, and a main body layer. The connecting flange layer has high flatness and a low coefficient of thermal expansion, ensuring the stability and durability of the installation. The reinforcing layer enhances the structural strength of the reflector through a honeycomb-shaped reinforcing rib design, while the array of heat dissipation holes further improves heat dissipation efficiency and prevents high temperature accumulation. The main body layer ensures the stability of the reflector in high-temperature environments through a high-reflectivity coating and reasonable material selection. This multi-protection design not only extends the service life of the reflector but also ensures the accuracy and reliability of the printing equipment during long-term operation.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Please see Figures 1-4 This utility model relates to a reflector structure for a banknote printing lamp, including a mounting frame 1, with a cover 2 fixedly connected to one side of the mounting frame 1. The surface of the cover 2 is provided with an efficiency-enhancing component, which includes a main reflection area 3 on one side of the cover 2, covering a 70° reflection angle and optimizing the light spot concentration through the radius of curvature; micro-reflection areas 4 on the other side of the cover 2, corresponding to 18° and 47° angles respectively, eliminating edge light attenuation; and a compensation reflection area 5 on one side of the mounting frame 1, providing 84° wide-angle coverage to compensate for optical path offset caused by installation errors. The efficiency-enhancing component... The components improve the reflectivity of the banknote printing lamp light; the surface of the mounting bracket 1 is provided with protective components, including a connecting flange layer 6 fixedly connected to the surface of the mounting bracket 1, the connecting flange layer 6 is made of 9.0mm stainless steel, which can provide a stable mounting reference; a reinforcing layer 7 fixedly connected to one side of the cover 2, the reinforcing layer 7 is made of 5.0mm titanium alloy, which can suppress high temperature deformation; and a main body layer 8 fixedly connected to the surface of the cover 2, the main body layer 8 is made of 2.8mm aluminum alloy, which can ensure the rigidity of the foundation. The protective components prevent the cover 2 from deforming due to high temperature.

[0024] Example 2

[0025] Please see Figures 1-4Based on Example 1, a positioning hole 9 is provided on one side of the inner cavity of the cover 2, and a mounting hole 10 is provided on one side of the inner cavity of the mounting bracket 1. The positioning hole 9 and the mounting hole 10 are 5mm and 6mm in size, respectively, which can be adapted to standard brackets, so that the cover 2 and the mounting bracket 1 form a snap-on quick-release structure, which can improve the installation efficiency. The surface is coated with a high reflectivity coating with a surface roughness Ra≤0.8μm. The high reflectivity coating reduces the energy loss of the UV light source. Combined with the secondary focusing design of the micro-reflection zone 4, the energy consumption of ink curing is reduced. The flatness of the connecting flange layer 6 is ≤0.05mm, and the coefficient of thermal expansion is 8.6×10. -6 / ℃, the flatness of the connecting flange layer 6 is ≤0.05mm, which can ensure a precise fit with the equipment bracket and prevent UV light leakage. Combined with the titanium alloy edge reinforcement layer 7, the high temperature deformation is reduced. The material of the cover 2 is honeycomb reinforcing ribs, and the honeycomb reinforcing ribs have an array of heat dissipation holes in their inner cavity.

[0026] The working principle of this utility model is as follows: The light emitted by the UV light source first illuminates the main reflective area 3 on the surface of the cover 2. The main reflective area 3, through an optimized radius of curvature design, concentrates and reflects the light onto the banknote printing area, ensuring the concentration of the light spot and the uniform distribution of the light. The micro reflective area 4 is located on the other side of the surface of the cover 2, with oblique angle designs of 18° and 47° respectively, to further refine the reflection and focus of the light, eliminate the attenuation of light at the edges, and ensure uniform coverage of the light in the entire printing area. The compensation reflective area 5 is located on one side of the surface of the mounting frame 1, designed with an 84° wide-angle coverage, mainly used to compensate for the optical path offset caused by installation errors. Through the reflection effect of the compensation reflective area 5, it is ensured that the light can still accurately cover the banknote printing area even under installation deviation, avoiding light waste or offset.

[0027] The protective components, through the synergistic action of the connecting flange layer 6, the reinforcing layer 7, and the main body layer 8, ensure the stability of the enclosure 2 in high-temperature environments. The connecting flange layer 6 is made of stainless steel, providing a stable installation reference. The reinforcing layer 7 is made of titanium alloy, which suppresses high-temperature deformation. The main body layer 8 is made of aluminum alloy, which ensures the rigidity of the foundation. The honeycomb reinforcing rib structure of the enclosure 2 and its internal heat dissipation hole array further improve heat dissipation efficiency, prevent high temperature accumulation, and ensure that the enclosure 2 will not deform due to high temperatures during long-term operation.

[0028] The high-reflectivity coating on the surface of the cover 2 has a roughness (Ra≤0.8μm) that effectively reduces the energy loss of the UV light source. Combined with the secondary focusing design of the micro-reflection area 4, the light reflection efficiency is further optimized, and the energy consumption of ink curing is reduced.
