Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, in particular to a publication UV curing printing device and a printing method with energy-saving effect. Background Art

[0002] UV curing (Ultraviolet Curing) is a technology that uses ultraviolet (UV) radiation to instantly harden materials such as coatings, inks, or adhesives. Its principle is to use ultraviolet rays to excite photoinitiators to produce free radicals or cations, thereby initiating polymerization reactions of monomers or prepolymers, and quickly converting liquid materials into solids. Compared with traditional thermal curing technology, UV curing has the advantages of fast curing speed, high energy efficiency, and strong environmental protection. No solvent is required during the UV curing process, which can significantly reduce the emission of volatile organic compounds (VOCs) and is more environmentally friendly. This technology is widely used in printing, electronic component packaging, optical fiber coating and other fields. In particular, in publication printing, UV curing technology has become a mainstream process because it can achieve high-quality and high-speed curing effects.

[0003] However, traditional UV curing systems often use mercury lamps as their light source, which suffer from high energy consumption, short lifespan, and high heat generation, making them difficult to meet the stringent energy conservation and environmental protection demands of modern industry. Furthermore, when the mercury lamp is fully illuminated, it radiates uniformly regardless of the print format. This fixed illumination pattern results in significant energy waste, especially on smaller print formats, where this problem is particularly severe. Summary of the Invention

[0009] Preferably, the light emitting area of ​​each light source module in the light source module array is 50-100 mm, and the combination of multiple light source modules covers a total area of ​​200-400 mm; The partition driving circuit adopts PWM pulse width modulation technology to adjust the output power of the light source module. The power output of each light source module can be dynamically adjusted according to the printing speed and coverage.

[0010] Preferably, a UV curing printing method for publications with energy-saving effect comprises the following steps: S1. Adjust the ink. Supply ink to the printing cylinder through the ink supply module. Use the built-in viscosity sensor and heating module to adjust the ink viscosity. Dynamically adjust the ink supply speed to match the cylinder speed to ensure uniform ink coating. S2.

After printing is completed, the ink coverage of the printed product is monitored in real time through the coverage sensor, and the ink supply is dynamically adjusted according to the coverage data; S4, dynamic UV curing, uses an LED-UV light source array to dynamically control the light emitting area according to the printing format, activating only the light source in the target area; a multi-layer reflective mask focuses the scattered UV light energy to the target area, and air cooling is used to maintain a stable curing chamber temperature; S5, energy-saving control, monitors the printing task status in real time through the energy-saving control module, and reduces the power of each module during short shutdowns or format switching; S6, quality inspection, using online detection devices to detect the ink adhesion status after curing, and dynamically adjust the ink supply or curing light source power according to the test results; S7, data recording and optimization, records the ink flow, curing power and coverage data during the printing process, and optimizes the printing parameters of the next batch based on historical data.

[0011] Preferably, in step S1, the viscosity sensor monitors the ink viscosity in real time and adjusts the output power of the heating module through the PID control algorithm to control the ink viscosity within the range of 50-200 mPa·s and the ink temperature is adjusted to 20-40°C.

The present invention provides a UV curing printing device and printing method for publications with energy-saving effects. The invention has the following beneficial effects: 1. This invention uses a zoned control design for the LED-UV light source array to dynamically adjust the light-emitting area according to the printing format, activating only the light source in the target printing area, thereby avoiding energy waste caused by lighting the light source across the entire printing area. At the same time, the multi-layer reflective light shield, through a high-reflectivity coating and optimized geometric design, concentrates scattered light on the target area, increasing UV light energy utilization to 85%-95%.

The ink supply module of this invention uses a viscosity adjustment unit to monitor and adjust ink viscosity and temperature in real time, ensuring that the ink maintains appropriate fluidity (viscosity range of approximately 50-200 mPa·s, temperature range of approximately 20-40°C). This ensures uniform ink application, reduces waste, and improves printing quality. Furthermore, the printing module uses a servo motor-driven fine-tuning mechanism to rapidly adjust the roller gap (accommodating paper thicknesses of 0.05-0.5 mm). Combined with high-speed roller operation (1-3 m / s), this meets the requirements of high-precision and high-efficiency printing. The high-efficiency light source curing in the UV curing module further increases production speed, allowing printed products to enter subsequent processes without long waiting times.

[0016] 3. This invention utilizes UV ink, eliminating the organic solvents found in traditional inks. This eliminates volatile organic compound (VOC) emissions and significantly reduces environmental pollution. Furthermore, the ink supply module incorporates a coverage sensor that monitors ink usage in real time and dynamically adjusts ink supply based on coverage, minimizing ink waste and improving resource efficiency. This environmentally friendly design ensures the device fully complies with modern environmental standards and is particularly suitable for large-scale applications in the publication printing industry.

[0017] 4. The UV curing module's intelligent temperature control system uses air cooling to effectively maintain the curing chamber temperature at 40-60°C, preventing high-temperature damage to printed paper and excessive wear of equipment components. Furthermore, the low-friction ceramic nanocoating on the printing cylinder significantly reduces operating resistance and mechanical wear, significantly extending the equipment's service life while ensuring reliability during long-term operation.

[0020] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see the attached Figure 1 -Attached Figure 5 The embodiment of the present invention provides a publication UV curing printing device with energy-saving effect, comprising: Ink supply module 1, used to store and deliver UV ink to the printing cylinder, and has ink viscosity and temperature regulation; Printing module 2, including multiple high-precision printing rollers with a low-friction nano-coating on the surface, suitable for paper of different thicknesses and materials; UV curing module 3, including LED-UV light source array 31, multi-layer reflective light shield 32 and intelligent temperature control system 33. LED-UV light source array 31 can dynamically adjust the light emitting area according to the printing format. Multi-layer reflective light shield 32 is used to focus light energy. Intelligent temperature control system 33 works by air cooling. The transmission module 4 adopts a chain conveying structure and is driven by a servo motor to convey printed materials; Energy-saving control module 5, used to dynamically manage the energy consumption of each module, capable of standby mode and real-time power adjustment; The control and monitoring module 6 is used to centrally control and monitor the operating status of the equipment, and can be remotely operated and abnormal alarms.

[0022] Specifically, the device adopts a zone-controllable LED-UV light source array to dynamically adjust the light-emitting area according to the printing format, activating only the light source in the target area, effectively avoiding the energy waste caused by lighting the light source of the entire format. Combined with the high reflectivity design of the multi-layer reflective light mask, the scattered light is concentrated and reflected to the target area, greatly improving the utilization rate of UV light energy to 85%-95%. In addition, the intelligent temperature control system in the UV curing module maintains the temperature of the curing chamber at 40-60°C, avoiding the impact of high temperature on equipment and paper. The roller surface of the printing module is coated with a low-friction ceramic nano-coating, which significantly reduces the running resistance and equipment wear, ensuring that the device has good stability and durability while operating efficiently.

[0023] UV curing module 3 includes: The light source module array consists of multiple independent light source modules, each of which covers a certain curing area and is equipped with a high-power UVLED chip, a heat dissipation substrate and an optical lens group; Partition drive circuit, used to independently control the switch state and output power of each light source module. Each light source module is connected to the central control system through an independent drive circuit; The central control system receives external input task parameters and data from sensors through an embedded processor, and dynamically adjusts the activation state and output power of the light source module according to the printing format and curing requirements; The sensor unit, including a format detection sensor, a coverage sensor and a speed sensor, is used to monitor the printing format width, UV ink coverage and printing speed in real time, and transmit the monitoring data to the central control system.

[0024] The light emitting area of ​​each light source module in the light source module array is 50-100mm, and the combination of multiple light source modules covers a total area of ​​200-400mm; The partition drive circuit uses PWM pulse width modulation technology to adjust the output power of the light source module. The power output of each light source module can be dynamically adjusted according to the printing speed and coverage.

[0025] Specifically, the zone-controlled LED-UV light source array is achieved through the following core technologies, involving hardware design, control logic, and sensor linkage, to ensure that the zoned activation and dynamic adjustment of the light source can accurately match printing needs: Modular light source design Array structure: The LED-UV light source array is designed to consist of multiple independent light source modules, each of which covers a certain printing format (such as 50mm or 100mm). These modules can be flexibly adapted to the total format range (200-400mm) through partitioning and combination.

[0026] Module packaging: Each light source module uses a high-power UVLED chip, which has high light intensity and long life. The module is equipped with a heat dissipation substrate (aluminum or copper) and high thermal conductivity materials to ensure thermal stability under long-term operation.

[0027] Independent drive circuit: Each module is equipped with an independent drive circuit, supporting separate lighting, shutdown and power adjustment functions.

[0028] Partition control logic Central control system: The system uses an embedded microprocessor (such as STM32, ARM chip) as the control core, and controls the switching state and output power of each light source module through PWM (pulse width modulation) technology.

[0029] Partition control circuit: Each light source module is connected to the central control system via a driver control circuit. The driver circuit receives control signals and independently switches the light source module on and off or adjusts its brightness based on task requirements. For example, only the area covered by paper will light up the corresponding light source module, while other areas will remain off to save energy.

[0030] Multi-mode operation: The control system supports multiple working modes, including: Full-format mode: Lights up all light source modules, suitable for large-format printing needs.

[0031] Dynamic partition mode: Dynamically activate the corresponding module according to the printing format.

[0032] Standby mode: When there is no task for a short period of time, the light source module is turned off or the output power is reduced to the minimum.

[0033] Sensor linkage Web detection sensor: Installing web detection sensors (such as infrared sensors or laser sensors) along the paper transport path detects paper width and position data in real time and sends this information to the central control system. The control system dynamically adjusts the activation area of ​​the light source module based on the sensor data.

[0034] Coverage sensor: The coverage sensor installed behind the printing cylinder is used to monitor the coverage of UV ink on the printed matter. If the coverage is low, the system will reduce the lighting range of the light source module or reduce the output power.

[0035] Speed ​​sensor: Detect the running speed of the printing cylinder and adjust the output power of the light source module according to the speed to keep the curing efficiency synchronized with the speed.

[0036] The inner surface of the multi-layer reflective light shield 32 is coated with a silver-based high-reflective coating with a reflectivity of not less than 95%, which is used to improve the utilization efficiency of UV light.

[0037] Specifically, the mask is designed as a multi-curved structure, which adopts a shape that combines a parabola and an ellipse, and can reflect the scattered UV light to the printing area to the greatest extent.

[0038] Silver-based high-reflective coatings, primarily made of silver (Ag), are widely used in optical and industrial applications requiring high light reflectivity. These coatings leverage silver's excellent optical properties, particularly its high reflectivity in the visible and ultraviolet ranges, to efficiently utilize light energy.

[0039] To further optimize the utilization of light energy, a sensor is embedded in the light shield to detect the efficiency of light energy reflection. When the reflection efficiency decreases, a cleaning reminder signal is issued to maintain long-term efficient operation.

[0040] The multi-layer reflective mask effectively improves the utilization efficiency of UV light and reduces the loss of unused light energy through high reflectivity coating and optimized geometric design. At the same time, it reduces the heat load of equipment operation and improves energy efficiency.

[0041] Although silver-based coatings have excellent optical properties, they are susceptible to oxidation or sulfurization. The following optimization strategies can improve their performance: Adding a dielectric protective layer (such as silicon dioxide or aluminum oxide) to prevent oxidation; Cover the coating surface with a transparent protective layer such as magnesium fluoride (MgF2) to reduce the possibility of sulfidation; Vacuum sputtering or chemical vapor deposition (CVD) processes are used to ensure coating thickness and uniformity for optimal optical performance.

[0042] The energy-saving control module 5 dynamically adjusts the power output of the ink supply module 1, the printing module 2 and the UV curing module 3 by collecting data on printing speed, printing width and curing requirements in real time.

[0043] Specifically, the energy-saving control module 5 includes a real-time monitoring unit, a power distribution unit, and a standby control unit. The real-time monitoring unit collects data such as printing speed, width, and ink coverage through embedded sensors and transmits the data to the power distribution unit.

[0044] Based on the monitoring data, the power distribution unit dynamically adjusts the power output of the ink supply module 1, printing module 2, and UV curing module 3. For example, when the coverage rate is lower than 50%, the power distribution unit proportionally reduces the light source power and the roller drive power.

[0045] When there is no printing task for a short period of time, the standby control unit reduces the equipment's energy consumption to 20%-40% of normal operating power, and uses an algorithm to predict the energy consumption required to resume the task, ensuring a quick response.

[0046] Through real-time monitoring and dynamic power allocation mechanisms, the energy-saving control module can significantly reduce the energy consumption of equipment operation, especially during printing intervals. The application of standby mode further reduces energy waste while maintaining the equipment's rapid recovery capability.

[0047] Furthermore, the control and monitoring module 6 is equipped with a touch screen and wireless connection unit. The touch screen displays the operating status, power consumption, and related parameters of each module in real time. The display interface is customizable and includes key data such as ink flow, roller speed, and curing strength.

[0048] The wireless connection unit supports remote operation and is connected to a mobile terminal or cloud management platform through the Internet of Things module, allowing users to check device status or adjust operating parameters at any time.

[0049] In addition, the control and monitoring module has a built-in historical data storage unit that can store operating parameters, energy consumption and equipment fault records for a long time, and supports data export function.

[0050] The combination of touch screen and wireless connection improves the convenience and intelligence of equipment operation; the historical data storage and analysis function provides data support for optimizing equipment operating efficiency and formulating maintenance plans, thereby improving equipment reliability and maintainability.

[0051] Please see the attached Figure 6 , a UV curing printing method for publications with energy-saving effect, comprising the following steps: S1. Adjust the ink. Supply ink to the printing cylinder through the ink supply module 1. Use the built-in viscosity sensor and heating module to adjust the ink viscosity. Dynamically adjust the ink supply speed to match the cylinder speed to ensure uniform ink coating. S2. Setting printing parameters, controlling the speed of the printing rollers through the servo motor, and adjusting the roller spacing according to the paper thickness using the automatic fine-tuning mechanism; S3. After printing is completed, the ink coverage of the printed product is monitored in real time through the coverage sensor, and the ink supply is dynamically adjusted according to the coverage data; S4, dynamic UV curing, using the LED-UV light source array 31 to dynamically control the light emitting area according to the printing format, activating only the light source in the target area; using the multi-layer reflective mask 32 to focus the scattered UV light energy to the target area, and using air cooling to maintain a stable curing chamber temperature; S5, energy-saving control, the energy-saving control module 5 monitors the printing task status in real time and reduces the power of each module during short shutdowns or format switching; S6, quality inspection, using online detection devices to detect the ink adhesion status after curing, and dynamically adjust the ink supply or curing light source power according to the test results; S7, data recording and optimization, records the ink flow, curing power and coverage data during the printing process, and optimizes the printing parameters of the next batch based on historical data.

[0052] Specifically, this method ensures that the ink is evenly applied under different environmental conditions by adjusting the ink viscosity and temperature in real time (viscosity range is approximately 50-200mPa·s, temperature range is approximately 20-40°C), thereby improving the accuracy and consistency of printing. Combined with a servo motor-driven roller fine-tuning mechanism, it can quickly adapt to paper of different thicknesses (0.05-0.5mm) and maintain high-precision printing when the roller is running at high speed (1-3m / s). The dynamic UV curing process utilizes a zoned controllable light source and an intelligent power distribution mechanism to ensure rapid curing of UV ink while reducing energy consumption. The overall process effectively reduces ink waste and optimizes energy distribution through coverage monitoring and dynamic adjustment of ink supply, achieving an efficient and energy-saving printing process.

[0053] In step S1, the viscosity sensor monitors the ink viscosity in real time and adjusts the output power of the heating module through the PID control algorithm to control the ink viscosity within the range of 50-200 mPa·s and the ink temperature to 20-40°C.

[0054] Specifically, in step S1, the UV ink is dynamically adjusted by the viscosity adjustment unit of the ink supply module 1. The ink viscosity is monitored in real time by a built-in viscosity sensor, and the viscosity range is adjusted to 50-200 mPa·s to meet different printing requirements.

[0055] Viscosity regulation is achieved through a PID control algorithm that adjusts the output power of the heating module based on sensor data, maintaining the ink temperature between 20-40°C to ensure proper ink flow and curing properties. The delivery unit is a constant-pressure pump equipped with a flow monitoring sensor, dynamically adjusting the ink supply rate to match the drum speed.

[0056] Through real-time viscosity adjustment and constant pressure ink supply design, the ink can be evenly applied at different temperatures and printing speeds, improving printing quality and reducing ink waste.

[0057] In step S2, the speed of the printing roller is adjusted to 1-3 m / s, and the roller spacing is adjusted to 0.05-0.5 mm according to the thickness of the paper.

[0058] Specifically, in step S2, a servo motor-driven fine-tuning mechanism adjusts the speed and pitch of the printing rollers. The roller speed is set between 1 and 3 m / s, depending on the paper thickness and material. The roller pitch is automatically adjusted, supporting paper thicknesses of 0.05 to 0.5 mm.

[0059] The surface of the roller is coated with a low-friction ceramic nano-coating to reduce the friction resistance of the paper during operation and ensure the smoothness of the printing process.

[0060] The precise adjustment of roller speed and spacing adapts to different printing materials, optimizes printing stability and consistency, while the low-friction coating design effectively reduces energy consumption and wear of the equipment.

[0061] In step S4, the light-emitting area of ​​the LED-UV light source array 31 is adjusted to 200-400 mm according to the printing format. The LED-UV light source array 31 includes an independent control circuit. Each light source module is activated or turned off according to the data of the format detection sensor, and the light energy utilization rate is increased to 85%-95% through the multi-layer reflective light shield 32.

[0062] Specifically, in step S4, dynamic UV curing is achieved through the LED-UV light source array 31. The light source array is designed as a partitioned controllable structure, dynamically lighting the required area according to the printing width of 200-400mm, and each light source module has an independent control circuit.

[0063] The multi-layer reflective mask 32 uses a silver-based high-reflective coating, combined with a parabolic structure with optimized curvature, to concentrate scattered light onto the target printing area, increasing light energy utilization to 85%-95%.

[0064] The heat during the curing process is controlled by the intelligent temperature control system 33. Air cooling and water cooling work together to ensure that the temperature of the curing chamber is stable at 40-60°C, avoiding paper deformation or equipment loss due to overheating.

[0065] The zoned controllable light source design and high-efficiency reflective light shield significantly improve the efficiency of UV light utilization and reduce the waste of uncured light energy. At the same time, the collaboration of the temperature control system ensures the stability of the curing process and the long-term reliability of the equipment.

[0066] In step S5, the energy-saving control module 5 dynamically allocates the power output of the ink supply module 1, the printing module 2 and the UV curing module 3 according to the drum speed, the paper width and the coverage data, and reduces the energy consumption to 20%-40% of the normal operating power when the equipment is idle.

[0067] Specifically, in step S5, the energy-saving control module 5 uses the real-time monitoring unit to collect data such as the roller speed, printing width, and ink coverage. Based on this data, the power distribution unit dynamically adjusts the power output of the ink supply module 1, the roller drive module, and the curing module. For example, when the coverage falls below 50%, the luminous power of the LED-UV light source array is reduced, and the speed of the roller drive module is lowered.

[0068] When the device has no printing tasks for a short period of time, the standby control unit reduces the power of the light source and driver module to 20%-40% of the normal operating power, and quickly increases the power when the task is resumed to avoid delays.

[0069] The energy-saving control module avoids unnecessary energy consumption by adjusting the power distribution of each module in real time, significantly reducing the overall power consumption of the device in standby mode, while ensuring the efficiency of the device's rapid resumption of operation.

[0070] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
