Description

Technical Field

[0001] This utility model relates to a varnishing device for tinplate printing, and particularly to a printing varnishing device with an air purification function. Background Technology

[0002] Varnishing involves applying (or spraying / printing) a layer of colorless, transparent coating to the surface of printed materials. After drying, it protects the material and enhances its gloss. A thin, uniform, transparent, glossy layer is formed on the surface of the printed material after leveling, drying, calendering, and curing. This process enhances the smoothness of the substrate surface and protects the printed image, serving as a finishing touch. Tinplate printing involves printing patterns onto a tin-plated sheet. It primarily utilizes the physical property of water and ink repulsion, using printing pressure to transfer the image from the printing plate onto the tin-plated sheet via a blanket. This is based on the principle of offset lithography.

[0003] Existing varnishing equipment for tinplate printing processes may generate harmful gases, such as formaldehyde and inhalable particulate matter, during the coating and drying processes. These harmful gases can be released into the production workshop, affecting the health of workers. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned technical problems, this utility model provides a printing and varnishing device with air purification function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a printing and varnishing device with air purification function, including a coating and varnishing mechanism and a drying mechanism. The drying mechanism is located after the coating and varnishing mechanism. The coating and varnishing mechanism and the drying mechanism share a conveying mechanism. It also includes an air purification mechanism. The air purification mechanism shares the same conveying mechanism with the coating and varnishing mechanism and the drying mechanism, and the air purification mechanism is located after the drying mechanism. The air purification mechanism includes a shell, a heating tube, an air purification layer, and a fan. The heating tube, the air purification layer, and the fan are all located inside the shell. The air purification layer includes, from bottom to top, activated carbon cloth, a first filter screen, and a second filter screen. The fan is located at the top of the shell and communicates with the interior of the shell. The heating tube is located below the air purification layer. The bottom of the shell has a conveying channel. The heating tube is located at the top of the conveying channel. The conveying mechanism passes through the conveying channel.

[0006] The conveying mechanism includes a conveyor belt that passes through the conveying channel.

[0007] The first filter is a HEPA (High Efficiency Particulate Air Filter), and the second filter is an activated carbon granular filter. The HEPA filter is made of stacked borosilicate microfibers, similar to paper, and can remove fine particulate matter from the air. The activated carbon granular filter has the highly efficient adsorption properties of activated carbon, capable of removing volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, and other airborne pollutants, providing excellent purification.

[0008] The beneficial effects of this utility model are as follows: The printing and varnishing equipment of this utility model, with an air purification function, has a heating tube located at the top of the conveyor channel, which heats the conveyor channel. After drying, the printed tinplate is further heated upon entering the conveyor channel, improving the drying effect. Simultaneously, the heating also promotes the volatilization of formaldehyde carried by the printed tinplate, achieving two benefits at once: improving both air purification and drying effects. In the air purification layer, the activated carbon cloth has excellent adsorption performance, is thin, and has good air permeability. Placing the activated carbon cloth at the bottom layer achieves initial filtration, directly filtering the generated industrial waste gas and facilitating easy replacement at a low cost. The first and second filters are respectively HEPA filters and activated carbon granular filters. The HEPA filter removes fine particulate matter from the air; the activated carbon granular filter has the highly efficient adsorption performance of activated carbon, removing volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, and other air pollutants, resulting in excellent purification.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 As shown, this utility model discloses a printing and varnishing device with air purification function, comprising a coating and varnishing mechanism 100 and a drying mechanism 200. The drying mechanism 200 is located after the coating and varnishing mechanism 100, and the coating and varnishing mechanism 100 and the drying mechanism 200 share a conveying mechanism. This utility model also discloses a printing and varnishing device with air purification function, further comprising an air purification mechanism 300. The air purification mechanism 300 shares the same conveying mechanism with the coating and varnishing mechanism 100 and the drying mechanism 200, and is located after the drying mechanism 200. The conveying mechanism is responsible for conveying the tinplate printed material, which has completed all color registration. The conveying mechanism first conveys the tinplate printed material to the coating and varnishing mechanism 100, where varnish is applied to the surface of the tinplate printed material. Subsequently, the tinplate printed material moves with the conveying mechanism to the area below the drying mechanism 200 for drying. After drying, the tinplate printed material is then conveyed by the conveying mechanism to the air purification mechanism 300.

[0016] like Figure 2-3 As shown, the air purification mechanism 300 includes a housing 1, a heating tube 2, an air purification layer, and a fan 3. The heating tube 2, the air purification layer, and the fan 3 are all located inside the housing 1. The air purification layer includes, from bottom to top, an activated carbon cloth 4, a first filter screen 5, and a second filter screen 6. The fan 3 is located at the top of the housing 1 and communicates with the interior of the housing 1. The heating tube 2 is located below the air purification layer. The bottom of the housing 1 has a conveying channel 7. The heating tube 2 is located at the top of the conveying channel 7, and the conveying mechanism passes through the conveying channel 7.

[0017] Preferably, the conveying mechanism includes a conveyor belt 8 that passes through the conveying channel 7.

[0018] Preferably, the first filter 5 is a HEPA filter and the second filter 6 is an activated carbon granule filter.

[0019] The working principle of this utility model of a printing and varnishing device with air purification function is as follows:

[0020] The conveyor mechanism is responsible for transporting the tinplate prints, which have already undergone all color registration. The conveyor mechanism first transports the tinplate prints to the coating and varnishing unit 100, where varnish is applied to the surface of the tinplate prints. Then, the tinplate prints move along with the conveyor mechanism to the drying unit 200 for drying. After drying, they undergo calendering and curing to complete the varnishing process. The drying unit 200 is responsible for drying the coated tinplate prints. After drying, the tinplate prints are then transported by the conveyor mechanism to the air purification unit 300. The heating element 2 in the air purification unit 300 is located at the top of the conveyor channel 7, thus heating the conveyor channel 7. The dried tinplate prints are further heated after entering the conveyor channel 7, improving the drying effect. Simultaneously, the heating also promotes the volatilization of formaldehyde contained in the tinplate prints, achieving two benefits: improving both air purification and drying efficiency. The air purification layer, from bottom to top, includes activated carbon cloth 4, a first filter 5, and a second filter 6. The activated carbon cloth is made by attaching powdered activated carbon to a non-woven substrate using a binder. It has excellent adsorption performance, is thin, and has good air permeability. This invention places the activated carbon cloth at the bottom layer for initial filtration, directly filtering industrial waste gas and facilitating easy replacement at a low cost. The first filter 5 and the second filter 6 are respectively HEPA filters and activated carbon granular filters. The HEPA filter is made of stacked borosilicate microfibers, similar to paper, and can remove fine particulate matter from the air. The activated carbon granular filter has the highly efficient adsorption performance of activated carbon, removing volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene, and other air pollutants, resulting in excellent purification.
