Description

Technical Field

[0001] The present invention relates to the technical field of vertical greening, and in particular to a vertical greening printing method, a greening circulation system and a greening science popularization and guidance system. Background Art

[0002] As the scale of cities continues to expand, urbanization has become one of the most significant trends in contemporary society. A large amount of natural ecological space has been occupied by cities, resulting in the continuous compression of urban green space, and the fracture and fragmentation of urban ecosystems have become more and more obvious. As an important part of the urban ecosystem, urban green space is closely related to the quality of life, health and happiness index of urban residents. In the current fast-paced modern life, people living in cities have a stronger desire to return to natural ecology and an increasing demand for green life. However, limited urban space makes the construction of flat public green space face the challenge of insufficient space, especially in high-density urban areas. Against this background, my country's urban greening construction is gradually paying attention to the expansion of vertical green space. Traditional vertical greening technology is mainly achieved through roof gardens and terraces, while new vertical greening technology effectively expands the green space of building facades through the innovation of supporting structures, which helps to improve the level of urban greening and promote the improvement of urban ecological environment. Vertical greening, as a greening method widely used in cities, has been proven to effectively absorb exhaust gas emitted by motor vehicles, adsorb suspended particles in the air, regulate air humidity, block direct sunlight, reduce the urban heat island effect, and reduce noise, thus playing a significant ecological benefit.

[0003] In view of this, it is particularly urgent to carry out research on new vertical greening technologies in order to give full play to its technical advantages and further expand urban green space. However, despite the many advantages of vertical greening technology, traditional vertical greening practices still face some challenges - frequent maintenance and management are required, resulting in high operating costs. In addition, in order to meet the needs of vertical greening, it may be necessary to transform and reinforce the existing building structure or attached structure, which not only increases the project cost, but also may affect the stability and safety of the structure. However, due to the long-term limitations of wall size and sunlight conditions, the growth environment of plants in vertical greening is restricted, which may lead to poor plant growth and thus affect the ecological effect of vertical greening. In addition, the species adaptability and community stability of plants in vertical greening are usually low. In order to ensure the landscape effect, it may be necessary to frequently change plant species. Therefore, constructing a vertical greening community with both good landscape effects and ecological functions, while meeting the requirements of low cost and easy maintenance, is an important scientific and technological problem faced in the current development of vertical greening technology.

[0004] With the improvement of global environmental protection awareness, the concept of urban green landscape construction has also shifted from a single aesthetic orientation to a greater focus on ecological sustainability, emphasizing the construction of natural habitats, aiming to improve the resistance of plant communities, species diversity, and reduce maintenance costs. On this basis, the present invention aims to propose an innovative landscape design concept that should follow the laws of nature, maintain ecological balance, and maximize economic and environmental benefits, so as to promote innovation and sustainable development of urban greening technology.

[0005] In the context of an era of material abundance, a single vertical plant display wall is facing the risk of being marginalized. The design of traditional plant display and guidance systems mostly adopts a flat layout or independent setting. Although this design is intuitive and easy to understand, it often lacks integration and interactivity with the surrounding environment, making it difficult for people to achieve a truly immersive experience and experience the charm of nature while enjoying the green ecology. At present, the combination of domestic display systems and guidance systems is mostly a hard combination, and problems often occur in a certain link of guidance or display. Although the addition of green elements is considered, it is often just a simple placement of some green plants or decorations, lacking a deep integration with the display content and guidance functions. This results in the green elements playing only a decorative role in the system, and failing to give full play to their ecological and popular science value. Moreover, when introducing plants into the display and guidance system, ensuring the long-term survival and good growth state of the plants is an important issue, but traditional maintenance methods often rely on manual management and maintenance, and it is difficult to ensure the continued health of the plants. In this process, the audience can often only passively accept information and cannot deeply understand the characteristics and value of plants, which limits the educational function and appeal of the display and guidance system. Therefore, it is particularly important to develop a new green ecological device that integrates popular science display and guide functions. This device should not only have the aesthetics and ecology of traditional plant displays, but also focus on harmonious coexistence with the surrounding environment. Through innovative design concepts and advanced technical means, people can not only appreciate the green ecology, but also gain a deep understanding of plant knowledge and feel the power of nature. Summary of the invention

[0006] In order to overcome the problem that the existing vertical greening system requires frequent maintenance and management, the present invention provides a vertical greening printing method, a greening circulation system and a greening science popularization and guidance system.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 This is a flow chart of the vertical greening printing method provided by the present invention. DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] like Figure 1 As shown, the present invention provides a vertical greening printing method.

[0024] The embodiments of the present invention provide a vertical greening printing method, a greening circulation system, and a greening science popularization and guidance system. The landscape greening and local endemic plants in the city are integrated into the vertical display wall to beautify the urban environment while enhancing the service function of the urban ecosystem. In order to solve the problems of growth sustainability, maintenance and management faced by vertical greening, the present invention proposes an innovative method, that is, by collecting and transforming natural resources in the city and the metabolites of plants on the vertical plant wall, to achieve the optimization of the plant growth environment and the ecological improvement of the urban space.

[0025] The first is to collect plant metabolites. During the growth of the vertical plant wall, plants produce oxygen, carbon dioxide, water vapor, organic matter, etc. through metabolic activities such as photosynthesis and respiration. These metabolites can be collected and analyzed through a closed or semi-closed growth environment combined with gas collection and analysis equipment. Secondly, the dust absorption function of the plant is evaluated. Plant leaves have the ability to absorb dust and particulate matter in the air. The dust absorption effect of the plant can be estimated by measuring the amount of dust on the surface of the leaves or regularly cleaning the surface of the leaves. Although it may be complicated to directly "collect" the particles absorbed by the plant, its dust absorption effect can be estimated by measuring the amount of dust on the surface of the leaves or regularly cleaning the surface of the leaves. In terms of soil fertility conversion monitoring, the soil sensors widely used in modern agricultural technology can monitor key parameters such as nutrient content (such as nitrogen, phosphorus, potassium, etc.) and pH value in the soil in real time, so as to understand the changes in soil fertility. Through reasonable fertilization and soil management measures, the conversion and maintenance of soil fertility can be promoted, thereby providing a better growth environment for plants. Finally, the collection of plant substances and environmental substances is integrated, integrating the plant's own material collection method with the device's own collection of environmental substances (such as moisture, minerals, temperature, etc.) to form a comprehensive environmental control and resource recovery system. For the collection of substances such as moisture, minerals and temperature in the environment, the existing technology is quite mature. For example, the use of humidity sensors and automatic irrigation systems can accurately control the water supply required by plants; the mineral content of the soil can be quickly analyzed by soil testing instruments, and the fertilization plan can be adjusted according to the results; the temperature sensor is used to monitor the temperature of the plant growth environment to ensure that it is within the appropriate range.

[0026] The core of this vertical greening method lies in the "printing"-like system described below. The system captures natural resources in the urban environment through resource collection devices, such as rainwater (rainwater collection is achieved by setting up a rainwater collection system using the top and ground of the device, including a rainwater collection surface, a filtration device and a water storage facility. Rainwater enters the primary filtration pool through the drainage pipe, and after removing large particles, it enters the multi-stage filtration system {such as sand filtration, activated carbon filtration, etc.} to ensure clean water quality.), carbon dioxide in the air (carbon dioxide in the air will be collected by chemical absorption or physical adsorption {such as using activated carbon, molecular sieves and other materials} or biological fixation {such as microalgae cultivation}. The implementation method is to set up a special collection device to capture and enrich carbon dioxide through air circulation. For example, in a plant cultivation system, carbon dioxide in the air is absorbed by photosynthesis and converted into organic matter, etc.), plant debris (such as fallen leaves, flowers, rotten leaves, etc.) and waste printing paper, etc. These resources are converted into a growth medium suitable for plant growth through a series of "collection, processing, and reorganization" steps. For example, rainwater continues to be purified through a multi-stage filtration system to ensure that the water quality meets irrigation standards; depending on the collection method, carbon dioxide may need to be further processed to remove impurities or convert it into a form that is more easily absorbed by plants (such as conversion into a carbonate solution); plant residues are decomposed and converted into nutrients and fertilizers that are easily absorbed by plants in suitable environmental conditions (by regulating the physical environment to promote microbial activity and accelerate the decomposition of residues, including regulating temperature, humidity and pH); the treatment of waste materials includes steps such as purification, crushing, screening, fiber separation and drying (for example, the waste "printing paper" mentioned above is crushed into fine particles or fibrous materials using a mechanical crusher after removing impurities and foreign matter. The crushed materials are screened to remove materials that do not meet the size requirements, followed by fiber separation to extract fibers, and finally dried {the crushed and processed materials usually contain a high amount of moisture, and the moisture content needs to be reduced through the drying process for subsequent use or storage}). The treated waste materials are mixed with other organic wastes {such as humus, biochar, etc.} in a certain proportion to form a new growth medium. During the mixing process, an appropriate amount of microbial agents can be added to promote the decomposition of organic matter and the release of nutrients. ) Inside the device, pretreated rainwater, carbon dioxide (such as converted into carbonate solution) and reconstituted growth medium are mixed. By controlling temperature, humidity, light, pH value and other conditions, microbial activity and chemical reactions are promoted, making the nutrients in the medium more balanced and easier to be absorbed by plants. And placed in a degradable film suitable for plant growth (natural or synthetic degradable materials such as PLA and PBS are selected, and processed into a shape and size suitable for plant growth through injection molding, film blowing and other processes.) and organic coatings. Specifically, a layer of organic coating containing growth medium and nutrients is coated on the surface of the membrane material.Organic coatings should have good air permeability and water retention, and organic silicone coatings, silicate coatings, and resins are selected to promote the growth of plant roots and the absorption of nutrients. The growth medium contained in the organic coating here can be the aforementioned recombined growth medium, or it can be an additional growth medium for easy implementation. Create a "printing carrier" suitable for plant growth. Then proceed to the "printing" step. During the printing process, the system uses a print nozzle to "print" the treated growth medium and collected plant seeds (note here: the plants originally selected are cold-resistant, moisture-resistant and aesthetically pleasing plants, so they also have long-term growth characteristics during the growth process to ensure the collection of metabolites and seeds. The selection of plant seeds takes into account the local climatic conditions and ecological environment to ensure that the plants can thrive on the vertical surface) layer by layer on the vertical surface. To achieve the function of "printing" the growth medium and nutrients layer by layer on the vertical surface, the principles of additive manufacturing (such as 3D printing) and automated spraying technology can be used for reference. However, it should be noted that the "printing" here is not printing in the traditional sense, but refers to applying materials layer by layer to the vertical surface. The design of the nozzle takes into account the growth needs and spatial layout of different plants, ensuring that the plants can grow according to the predetermined pattern and density. For example, a vertical 3D printer can be used, or a customized device based on the transformation of an existing 3D printer. At the same time, the system will automatically adjust the operation of the nozzle according to changes in environmental parameters, such as light intensity, temperature and humidity, and control the movement trajectory and spraying speed of the spray gun by a computer, so that accurate layer-by-layer application can be achieved. An industrial-grade automatic sprayer can be used, equipped with an adjustable spray gun and a control system. Ensure the accuracy and efficiency of the printing process. In this embodiment, the cultivation medium is composed of a growth medium, a degradable membrane material, and an organic coating with good air permeability and water retention. In terms of material selection, the cultivation medium uses an environmentally friendly and degradable material, which not only has good water retention and air permeability, but also can effectively absorb and transform harmful substances in the environment. After that, the printed "print carrier" (i.e., the formed "print paper") is placed behind the plant grown in the previous period, allowing the plant to self-replace and the life cycle of the vertical plant wall is extended and the maintenance and maintenance costs of the vertical plant wall are saved. The "printing carrier" here refers to the object to be printed before the printing operation is performed, and the "printing paper" here refers to the printing carrier obtained after the printing operation is performed, which includes the growth medium and plant seeds.

[0027] The vertical greening printing method is used for vertical greening, and the vertical greening includes a plant wall for plant growth, which includes the following steps: collecting natural resources in the urban environment, collecting plant seeds on the plant wall; processing the collected natural resources and reorganizing them into growth media; coating the surface of a degradable membrane material suitable for plant growth with an organic coating having air permeability and water retention; using the entirety of the membrane material and the organic coating as a printing carrier, and printing the mixed growth medium and the collected plant seeds layer by layer onto the printing carrier through a printing nozzle to form printing paper.

[0028] The related expressions of plant wall and vertical plant wall in this application correspond to the vertical display wall here. The reason for expressing them as plant wall and vertical plant wall is to facilitate a better understanding of their maintenance and their life cycle.

[0029] The natural resources in the urban environment here include those produced by the plant’s own metabolism and those from the external environment.

[0030] Preferably, the growth medium contained in the organic coating may be the aforementioned recombinant growth medium, or may be an additional growth medium for ease of implementation.

[0031] The present invention provides a vertical greening printing method, which converts all collected resources into growth media through the steps of "collection, processing, and reorganization", collects plant seeds in the device, and places the two on a "printing carrier" composed of membrane materials and organic coatings. When in use, the "printing paper" is placed behind the plants grown in the previous period, that is, on the back of the vertical display wall in this embodiment. The vertical display wall is arrayed with multiple planting holes, and the plant seeds can grow to the front of the vertical plant wall through the planting holes. The growth medium is used as a part of the cultivation medium. Allowing plants to self-renew, the life cycle of the vertical plant wall is extended, and the maintenance and upkeep costs of the vertical plant wall are saved.

[0032] In order to ensure the healthy growth of plants on the vertical plane, the greening circulation system proposed in the present invention integrates the aforementioned vertical greening printing method and intelligent growth management technology. The system monitors the growth status of plants in real time through a built-in sensor network, including growth rate, nutritional status, and pest and disease status. It is planned to adopt means such as growth status monitoring, nutritional status assessment, pest and disease monitoring, and environmental regulation, and set up growth rate sensors. The system can quantify the growth rate of plants and estimate their growth rate by measuring morphological parameters such as plant height and leaf area; use soil nutrient sensors and chlorophyll meters and other equipment to quantitatively analyze the nutritional status of plants to ensure that plants obtain appropriate nutritional supply; use advanced infrared thermal imaging technology and image recognition systems to carefully inspect the surface of plants to detect early signs of pests and diseases. According to the data collected by the sensor, the system will automatically adjust the supply of light, water and nutrients to create the most suitable growth conditions and optimize the physiological state of plants.

[0033] In addition, in order to improve printing efficiency and reduce costs, the present invention also adopts modular design and the application of recyclable materials: the modular design concept allows flexible assembly and disassembly of printing modules according to specific application scenarios and needs, thereby enhancing the adaptability and convenience of the system. The use of recyclable materials in the printing process not only reduces economic costs, but also reduces the impact on the environment, which is in line with the principle of sustainable development.

[0034] Furthermore, the greening circulation system also integrates guidance and popular science display functions, adopts intelligent forms and interactive elements (such as QR codes), and sets guidance signs and information display boards on the vertical display wall. It can not only provide directional guidance for visitors and provide richer interactive information, but also popularize scientific knowledge such as the growth cycle and characteristics of plants, thereby enhancing citizens' ecological awareness and scientific literacy.

[0035] The greening circulation system proposed in the present invention also fully considers the concept of efficient utilization of energy value and energy circulation. Specifically, throughout the life cycle of the plant wall, the metabolic process of the plant will produce energy and temperature changes, which are essentially an underutilized energy source. These energy values ​​can be collected and converted by specific devices, such as thermoelectric generators (TEGs) or thermal energy collection systems, which can convert the heat generated by the plant wall into electrical energy or other forms of energy; the temperature changes of the plant wall can be used by the integrated temperature regulation system to assist in regulating the microclimate of the surrounding environment and reduce dependence on traditional air-conditioning systems or heating systems; the collected energy can also be used to support the energy needs of the plant wall itself, such as lighting, water supply and nutrient delivery systems. Through the above method, the vertical plant "printing" technology not only improves the ecological value of the plant wall, but also reduces the carbon footprint and environmental impact of the system through efficient utilization and circulation of energy, enhances the sustainability of the system, and provides an innovative solution for urban greening and energy utilization.

[0036] Thus, the vertical plant "printing" method of the present invention realizes efficient, environmentally friendly and durable urban vertical greening by integrating environmental collection, material processing and precision printing and other technical means. This method not only improves the urban greening coverage rate, but also provides strong support for the sustainable development of the city. By promoting the construction of green infrastructure, it provides an effective tool for cities to cope with climate change, resource recycling and environmental quality management. In terms of the beauty of urban streets, the innovative vertical plant "printing" method improves the urban landscape, enhances the visual appeal and aesthetic value of the city; it has both popular science education functions and can enhance the public's awareness of the importance of environmental protection and sustainable development. In terms of energy utilization, this method improves the efficiency of energy use and reduces the city's dependence on traditional energy by integrating energy collection and conversion technology. This method embodies the cross-integration of multiple disciplines such as ecology, urban planning, environmental engineering and sociology, and brings a comprehensive solution to the field of urban greening.

[0037] Specifically, the greening science popularization and guidance system includes the following modules:

[0038] Main plant metabolism and seed collection module: ① Seed collection mechanism: The system is equipped with a mechanical vibration device and a wind-assisted system to promote the shedding of seeds during the maturity period of plants. The vibration device induces the seeds to separate naturally from the fruit through precisely controlled vibration frequency and amplitude. The wind-assisted system guides the fallen seeds to the designated collection area through directional airflow. ② Seed treatment: The collected seeds are initially screened and cleaned to remove impurities and immature seeds to ensure the purity and quality of the seeds. Subsequently, the seeds are dried and stored to maintain their vitality and extend their storage life. ③ Seed management: The system has seed counting and classification functions. Through high-precision counters and classification devices, it can achieve accurate management and tracking of seeds, providing convenience for subsequent planting and management. ④ Plant metabolism collection system: A multi-layer, porous, and breathable collection plate is set inside the plant wall to ensure that the water vapor, carbon dioxide and other gases released by the plants can pass through smoothly, while effectively intercepting solid substances such as plant fallen leaves and pollen. ⑤ Collection plate design: The collection plate is made of materials that are easy to disassemble and clean, which is convenient for regular cleaning and replacement to ensure collection efficiency and system hygiene. ⑥ Biological decomposition and recycling: The collected plant residues are sent to the biological decomposition device for treatment. The plant residues are converted into organic fertilizers using microbial decomposition technology to realize the resource utilization of plant metabolites. ⑦ Gas recycling: The gas generated during the biological decomposition process can be reused in the photosynthesis of the plant wall or other needs after filtration and purification, realizing the recycling of gas. ⑧ Intelligent environmental monitoring and control: Through the sensor network connected to the plant wall intelligent management system, the humidity, temperature, gas concentration and other parameters of the environment inside the plant wall are monitored in real time. According to the monitoring results, the system automatically adjusts the number, position and angle of the collection plates, as well as the working status of the biological decomposition device, to optimize the efficiency and effect of the collection and treatment process.

[0039] Environmental material collection module: This part of the device collects dust, temperature, and moisture in the environment to ensure the device's own circulation and the exchange and supply of additional materials. ① Dust and suspended matter capture: By setting an electrostatic field on the top of the device or using high-efficiency filter materials, dust and suspended particles in the air can be effectively captured. ② Solid waste conversion: The collected dust and suspended matter are compressed and solidified to be converted into organic fertilizer for use in plant walls or other recycling. ③ Organic coating technology: A layer of organic coating containing growth medium and nutrients is applied to the surface of the device. The coating should have good air permeability and water retention to promote the growth of plant roots and the absorption of nutrients. ④ Natural precipitation collection and multifunctional utilization: The structured design collects natural precipitation such as rainwater and dew, and stores it through an internal water storage system, and supplies it to the plant wall by drip irrigation or sprinkler irrigation. Excess water can be used for other functions such as cleaning and cooling to achieve efficient use of water resources. ⑤ Gaseous pollutant control: The device is equipped with high-efficiency adsorption materials such as activated carbon, biofilm, etc. to absorb harmful substances in motor vehicle exhaust and air. Through catalytic reactions, biodegradation and other methods, the absorbed harmful substances are converted into harmless substances to reduce environmental pollution. ⑥ Energy collection and conversion: The surface of the device uses high-efficiency solar panels and thermal energy collection materials to collect sunlight and environmental heat energy respectively, providing electrical energy and thermal energy for the device. ⑦ Energy collection and conversion: The device is equipped with high-precision humidity and temperature sensors to monitor the environmental humidity and temperature in real time. According to the monitoring data, the humidity and temperature inside the device are automatically adjusted to ensure that the plant wall is in the best growth state. ⑧ Noise pollution control: Sound insulation materials and noise absorption structures are used to reduce noise pollution, and part of the noise energy is converted into electrical energy through a vibration energy conversion device to provide auxiliary energy for the device.

[0040] Resource collection and pretreatment module: The design of this device focuses on converting the device itself and environmental resources into growth media and nutrients suitable for plant growth through a series of pretreatment steps, and further turning them into "printing paper" suitable for plant growth. Maximize the use of resources and promote the healthy growth of plant walls. ① Resource collection mechanism: The system first collects waste generated by the device itself (such as discarded "printing paper", plant debris, etc.) and environmental resources (such as rainwater, sunlight, carbon dioxide in the air, etc.). ② Resource purification treatment: Use advanced purification technologies such as filtration, adsorption and chemical treatment to remove harmful substances and impurities to ensure the purity of resources. (For example, rainwater is filtered to remove suspended matter, and carbon dioxide in the air is purified to remove dust and other pollutants.) ③ Physical crushing process: The purified resources are physically crushed by a crusher to form fine particles or powder, which provides a basis for subsequent mixing and reorganization. ④ Mixed reorganization of medium and nutrients: The crushed particles or powder are mixed with necessary nutrients and growth regulators to form a medium suitable for plant growth. ⑤ Application of degradable membrane materials: Degradable membrane materials and organic coatings are selected as carriers of plant growth media. These materials have good environmental performance and suitable physical properties, such as air permeability and water retention, which are conducive to plant growth. ⑥ Preparation of "plant printing paper": The pretreated and reorganized medium and nutrients are evenly coated on the degradable film and organic coating to form "printing paper" suitable for plant growth. During the preparation process, the system uses strict quality control measures to monitor the pH value, nutrient content, microbial activity and other indicators of the medium to ensure that the medium can meet the growth needs of plants, and conducts environmental impact assessments on the entire resource collection and pretreatment process to ensure that its operation meets the requirements of ecological protection and sustainable development.

[0041] Application method: ⑦ Automated application: The prepared "printing paper" can be taken out of the storage area and accurately laid to the designated position through automated devices such as conveyor belts or rollers. ⑧ Fixing and laying: During the laying process, use suction cups or sticky rollers to fix the "printing paper" to ensure that it fits tightly against the plant wall or soil surface. After laying directly on the back of the plants currently growing on the plant wall, provide the plants with the medium and nutrients needed for growth. ⑨ Nutrition supply: As the plants grow and develop, the nutrients in the "printing paper" will gradually be absorbed and utilized. ⑩ Intelligent monitoring and maintenance: When the plants reach the withering period or the growth medium in the "printing paper" becomes inactive, the system can automatically detect and replace or supplement it to ensure the continued growth and health of the plant wall.

[0042] Seed and growth medium printing module: adopts an innovative layer-by-layer printing technology to achieve efficient and orderly construction of plant walls. ① Printing technology: The system adopts high-precision printing nozzle technology to accurately "print" the processed growth medium and collected plant seeds layer by layer onto the vertical surface. ② Nozzle design: There are multiple fine nozzles inside the printing module for spraying growth medium and plant seeds to ensure that each layer can be evenly covered. ③ Intelligent control system: The nozzle system realizes precise operation through the intelligent control system. According to the preset arrangement and density requirements, it automatically adjusts the spray angle, speed and frequency of the nozzle to ensure that each layer of growth medium and plant seeds is evenly distributed and meets the design requirements. ④ Consideration of plant growth needs: The system fully considers the growth needs of different plants, including light, water, nutrition, etc., as well as the rationality of spatial layout. ⑤ Printing parameter optimization: Through computer-aided design (CAD) and computer-aided manufacturing (CAM) technology, the printing parameters are optimized to meet the specific needs of different types of plants. ⑥ Printing accuracy control: The system uses high-precision sensors and actuators to monitor and adjust the growth medium and seed spraying during the printing process in real time to ensure printing accuracy. ⑦Material compatibility: The print heads and related components used in the system have a high degree of material compatibility and can handle various types of growing media and seeds. ⑧Environmental adaptability: The printing module can automatically adjust the printing parameters according to changes in environmental conditions, such as temperature, humidity, etc., to adapt to different environmental conditions.

[0043] "Printing paper" recycling and replacement module: adopts an automation and energy recycling design concept to achieve energy recycling, environmental protection of the printing process and harmonious coexistence with the environment. ①Automatic replacement mechanism: The device is equipped with a set of sophisticated mechanical systems, including "printing paper" reels, conveyor belts, guide mechanisms and automatic paper changing mechanisms.
