Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to environmentally friendly printing equipment which integrates offset printing and digital printing. Background Art

[0002] During offset printing, a lot of waste gas will be generated, which will pollute the entire workshop, endanger the health of employees, and cause the workshop's environmental protection to fail to meet standards. However, the existing offset printing equipment does not have centralized waste gas collection and treatment equipment, making it difficult to effectively collect waste gas.

[0003] An environmentally friendly printing device that integrates offset printing and digital printing with authorization announcement number CN213261618U discloses a spray plate and a third fixed frame. The waste gas generated during the printing operation of the printing device body is sucked into the interior of the first fixed frame through a vacuum pump. The spray plate sprays out the neutralizing liquid inside the water tank, so that the neutralizing liquid can fully contact the waste gas, and most of the sulfide or acidic substances in the waste gas can be purified to achieve harmless treatment and discharge of the waste gas. The device is provided with a third fixed frame, and the purified humid air is dried by the third fixed frame to prevent the staff from working in a humid environment for a long time and affecting their health.

[0004] The above-mentioned device can clean up a large amount of waste gas generated by the printing machine during the printing process, which is helpful for protecting the air environment. However, during the purification process, the above-mentioned device makes the waste gas contact with the sprayed liquid by spraying, which will cause insufficient contact and affect air purification. In view of this situation, the utility model proposes a new solution. Utility Model Content

[0007] The atomizing device comprises an atomizing cylinder, the other end of the atomizing cylinder is fixedly connected with a tail cylinder, and the bottom end of the tail cylinder is connected with a collecting tank for collecting liquid.

[0008] Preferably, a top frame is fixedly connected to the bottom end of the air inlet, the top frame is communicated with the inside of the air inlet, and the air inlet is rotatably connected to the paddles between the inner walls on both sides, wherein a motor for driving the paddles is installed on the outside of the air inlet.

[0012] Preferably, an exhaust port is provided near the top of the tail cylinder, and the cooling plates are all copper plates.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The environmentally friendly printing equipment that integrates offset printing and digital printing uses an atomizing cylinder with a concave bottom and a resistance wire to achieve uniform heating and atomization of droplets, improving the quality and stability of atomization. In addition, the setting of the water inlet pipe and the water diffuser allows the water source to enter the atomizing cylinder evenly, further optimizing the atomization effect. This design allows the waste gas to contact the treatment liquid in large quantities and evenly, improving the quality of waste gas treatment.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Traditional offset printing is based on ink and uses a lot of organic solvents, which causes a certain degree of environmental pollution. Digital printing uses liquid ink, which reduces the use of chemical substances and reduces the impact on the environment. Therefore, digital printing has the advantage of environmental protection. At present, some printing equipment manufacturers have begun to launch equipment that integrates offset printing and digital printing. These equipment combine the high speed and high quality characteristics of offset printing with the personalized and variable data characteristics of digital printing. They usually use environmentally friendly inks such as water-based inks and UV inks, and reduce the use of chemical substances in the printing process, reducing the emission of wastewater and exhaust gas, but still have certain exhaust gas pollution.

[0022] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: an environmentally friendly printing device integrating offset printing and digital printing, comprising an air inlet 1, both ends of the top of the air inlet 1 are fixedly connected with a filter 5, and the other end of the filter 5 is provided with an atomizing device 6;

[0023] The atomizing device 6 comprises an atomizing tube 601 , the other end of which is fixedly connected to a tail tube 7 , and the bottom end of the tail tube 7 is connected to a collecting tank 8 for collecting liquid.

[0024] To ensure the smooth implementation of this embodiment, it is necessary to understand that a top frame 4 is fixedly connected to the bottom end of the air inlet 1, the top frame 4 is communicated with the inside of the air inlet 1, and is rotatably connected to the paddle 2 between the inner walls on both sides of the air inlet 1, wherein a motor 3 for driving the paddle 2 is installed on the outside of the air inlet 1.

[0025] To ensure the smooth implementation of this embodiment, it is necessary to understand that the bottom of the atomizer tube 601 is recessed, and a resistance wire 10 capable of heating is provided at the recessed portion. A water inlet pipe 11 connected to the inside of the atomizer tube 601 is fixedly connected to the top of the atomizer tube 601, and a water dispersion sheet is fixedly connected to the bottom of the water inlet pipe 11.

[0026] To ensure the smooth implementation of this embodiment, it is necessary to understand that a plurality of cooling plates 13 are fixedly connected to the top of the tail cylinder 7. The cooling plates 13 extend from the top of the tail cylinder 7 to the connection between the atomizing cylinder 601 and the tail cylinder 7. A cooling fan 9 is installed on the top of the cooling plates 13.

[0027] To ensure the smooth implementation of this embodiment, it should be understood that one end of the filter 5 is screwed to one end of the atomizing tube 601 , and the collecting tank 8 is also screwed to the bottom end of the tail tube 7 .

[0028] In order to ensure the smooth implementation of this embodiment, it should be understood that an exhaust port 12 is provided near the top of the tail cylinder 7 and the cooling plates 13 are all copper plates.

[0029] This device integrates multiple components such as an air inlet 1, a filter 5, an atomizing device 6, and a tail cylinder 7, which together provide support for waste gas cleaning during the printing process.

[0030] First, the air inlet 1 is connected to the interior through the top frame 4, ensuring the stability of the airflow direction. The wind propeller 2 rotates between the inner walls on both sides of the air inlet 1 and is driven by the motor 3, making the air flow more uniform and efficient. This design helps the exhaust gas to be evenly sucked into the device.

[0031] The atomizing device 6 is another core component, which includes an atomizing tube 601 and a tail tube 7, wherein the bottom of the atomizing tube 601 is recessed and provided with a resistance wire 10 for heating. This design enables the droplets to be evenly heated during the atomization process to achieve an atomization effect, thereby improving the atomization effect and stability. The provision of the water inlet pipe 11 and the water dispersion sheet enables the water source to evenly enter the atomizing tube 601, further optimizing the atomization effect. Under this condition, the exhaust gas can be in large quantities and evenly contact with the treated liquid, thereby improving the quality of exhaust gas treatment. The design of the tail tube 7 is equally important. It is fixedly connected to a plurality of cooling plates 13 on the top. These cooling plates 13 extend from the top of the tail tube 7 to the connection between the atomizing tube 601 and the tail tube 7. When the atomized gas enters the tail tube 7, it can quickly liquefy and drip downward after contacting the cooling plates 13, thereby collecting the waste liquid. In summary, the cooling fan 9 further accelerates the cooling process, improves the cooling efficiency of the equipment, and improves the liquefaction efficiency. Other components such as the filter 5 and the collecting tank 8 also play an indispensable role. The filter 5 is used to filter impurities in the air and filter the exhaust gas generated during the printing process of the printer. The collecting tank 8 is used to collect the waste liquid generated after the exhaust gas purification during the printing process to avoid pollution to the environment. The screw connection method of these components not only ensures the stability and reliability of the equipment, but also makes the disassembly and maintenance of the equipment more convenient and quick. The exhaust port 12 is located near the top of the tail cylinder 7, which helps to discharge the treated exhaust gas out of the equipment, thereby reducing the pollution to the indoor air. The cooling plate 13 is a copper plate with good thermal conductivity, which can quickly export heat and improve the cooling efficiency of the equipment.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
