[0002] Tinplate typically refers to a metallic material made by plating a thin layer of tin onto the surface of cold-rolled low-carbon steel sheets. It possesses excellent sealing properties, corrosion resistance, and ductility, making it commonly used to manufacture various packaging containers such as food cans, beverage cans, and gift boxes. To enhance the aesthetics of the packaging containers and clearly convey product information to consumers, the tinplate used for making these containers is usually printed. After printing, the tinplate needs to undergo drying and cooling processes.
[0003] Chinese patent document CN217047926U discloses a high-efficiency cooling device for tinplate printing. This device uses bearings to rotate a lever, allowing the operator to easily flip the tinplate sheet using a handwheel, enabling a fan to continuously cool both ends of the sheet. However, this cooling device requires manual operation and is unsuitable for continuous production. Utility Model Content
[0004] The purpose of this invention is to provide a cooling device for tinplate printed products, which aims to solve the problem that existing high-efficiency cooling devices for tinplate printing require manual operation and cannot be used in continuous production operations.

[0008] An induced draft fan is mounted on the top plate, with its lower end located at the air inlet.
[0009] An air guide box is installed on the second side cabinet, with its upper end connected to the air outlet of the induced draft fan and its lower end connected to the air duct.
[0010] An exhaust fan is installed on the top plate, with its lower end located at the air intake.
[0011] Optionally, multiple induced draft fans are distributed at intervals along the length of the second side cabinet; the number of air guide boxes is the same as the number of induced draft fans.

[0019] Beneficial effects:
[0020] This utility model provides a cooling device for tinplate printed products. By setting a top plate above the circulating chain, installing an exhaust fan on the top plate, and installing an air guide box on the second side cabinet below the top plate, when the cooling device is working, the exhaust fan can guide the air used to cool the tinplate printed products through the air guide box into the air duct in the second side cabinet, and then blow it out through the cold air outlet, thereby cooling the tinplate printed products carried by the iron sheet carrier on the circulating chain.

[0035] Please see Figures 1 to 6 This utility model provides a cooling device for tinplate printed products. This cooling device can be used in conjunction with existing tinplate printed product drying lines and is located downstream of the drying line. Specifically, the cooling device includes a first side cabinet 1, a second side cabinet 2, a top plate 5, an exhaust fan 6, an air guide box 7, and an exhaust fan 8.
[0036] The first side cabinet 1 and the second side cabinet 2 are arranged opposite each other. A circulating chain 3 is rotatably positioned between the first side cabinet 1 and the second side cabinet 2, and each link of the circulating chain 3 is equipped with a sheet metal carrier 4 for supporting tinplate sheets. It should be noted that the circulating chain 3 and the sheet metal carrier 4 are basic components of a tinplate printing production line, and their structure can be referenced in Chinese Patent Document CN211000459U. It is understood that when the cooling device for tinplate printing products provided by this utility model is used in conjunction with the drying line, the circulating chain 3 can be simultaneously arranged on both the drying line and the cooling device, thereby allowing the tinplate printing products to be immediately transported to the cooling device for cooling after being dried by the drying line. To transfer the tinplate sheets to the sheet metal carrier 4, a transition conveyor belt 14 needs to be provided at the input end of the circulating chain 3. The structure of the transition conveyor belt 14 can be referenced in Chinese Patent Document CN211000459U.
[0037] Furthermore, the second side cabinet 2 is equipped with an air duct, and the side of the second side cabinet 2 facing the first side cabinet 1 has multiple cold air outlets 201; the cold air outlets 201 are connected to the air duct. The top plate 5 is fixedly mounted above the first side cabinet 1 and the second side cabinet 2, and the top plate 5 is equipped with an air inlet 501 and an exhaust outlet 502. The exhaust fan 6 is mounted on the top plate 5, and the lower end of the exhaust fan 6 is used for air supply and is located at the air inlet 501, while the upper end of the exhaust fan 6 has an air intake for drawing in air at normal ambient temperature in the workshop. The air guide box 7 is mounted on the second side cabinet 2, and the upper end of the air guide box 7 is connected to the air outlet at the lower end of the exhaust fan 6, while the lower end of the air guide box 7 is connected to the air duct; the exhaust fan 8 is mounted on the top plate 5, and the lower end of the exhaust fan 8 is located at the exhaust outlet 502.
[0038] When the cooling device is working, the air intake at the top of the induced draft fan 6 draws in air at normal ambient temperature (i.e., cold air) from the workshop. The induced draft fan 6 then introduces the air into the air guide box 7, and through the air guide box 7, the air is guided into the air duct in the second side cabinet 2. Finally, it is blown out through the cold air outlet 201, thereby cooling the tinplate printed products carried by the iron sheet carrier 4 on the circulating chain 3. This cooling of continuously conveyed tinplate printed products can be achieved without manual intervention, meeting the needs of continuous production of tinplate printed products. Simultaneously, the exhaust vent 502 on the top plate 5, in conjunction with the exhaust fan 8, can promptly extract the hot air formed after absorbing heat from the tinplate during the cooling process, preventing the accumulation of hot air in the conveying space of the circulating chain 3 and ensuring the cooling effect on the tinplate printed products is not affected.
[0039] For example, the induced draft fan 6 can be a CF-11 type multi-blade centrifugal induced draft fan, but is not limited to this type. The exhaust fan 8 can be a T35-11 type axial flow exhaust fan, but is not limited to this type.
[0040] like Figure 3 As shown, in an optional embodiment, multiple exhaust fans 6 are spaced apart along the length of the second side cabinet 2; the number of air guide boxes 7 is the same as the number of exhaust fans 6, with each exhaust fan 6 equipped with one air guide box 7. In this embodiment, the spaced distribution of multiple exhaust fans 6 can form multi-point air supply along the length of the second side cabinet 2. Combined with their respective corresponding air guide boxes 7, air can be guided into the air ducts within the second side cabinet 2, avoiding uneven airflow distribution at different locations within the air duct due to distance differences when a single exhaust fan 6 supplies air. This ensures that the cold air blown from the cold air outlet 201 is more evenly distributed between the first side cabinet 1 and the second side cabinet 2, thereby guaranteeing a stable cooling effect for tinplate printed products on different sheet metal carriers 4. Moreover, when one of the exhaust fans 6 malfunctions, only the malfunctioning exhaust fan 6 needs maintenance; therefore, the cooling device can continue to operate without affecting the production efficiency of tinplate printed products.
[0041] In this invention, the length direction of the circulating chain 3 is parallel to the length directions of the first side cabinet 1 and the second side cabinet 2.
[0042] like Figures 1 to 3 ,as well as Figure 5 As shown, in an optional embodiment, multiple exhaust fans 8 are spaced apart along the length of the second side cabinet 2; an exhaust hood 9 is fixedly installed below the top plate 5; the number of exhaust hoods 9 is the same as the number of exhaust fans 8, and the top of the exhaust hood 9 has an opening 901 communicating with the exhaust port 502. In this embodiment, multiple exhaust fans 8 are spaced apart along the length of the second side cabinet 2, which can realize multi-point synchronous exhaust and avoid the problem of hot air accumulation and reduced cooling effect caused by the limited exhaust coverage of a single exhaust fan 8.
[0043] Similarly, when one of the exhaust fans 8 malfunctions, only the malfunctioning exhaust fan 8 needs to be maintained, and the production efficiency of tinplate printed products will not be affected.
[0044] like Figures 1 to 3 ,as well as Figure 5 As shown, in an optional embodiment, the upper part of the exhaust hood 9 is conical, which can converge and guide the airflow during the exhaust process. When the exhaust fan 8 draws hot air through the exhaust hood 9, it can reduce the diffusion and retention of hot air in the exhaust hood 9, thereby effectively expelling the hot air from the conveying space of the circulation chain 3, and thus ensuring the cooling effect of the tinplate printed products.
[0045] like Figures 1 to 5 As shown, in an optional embodiment, an exhaust pipe 10 is fixedly fitted onto the upper end of the exhaust fan 8; the exhaust end of the exhaust pipe 10 is located outside the workshop. By directly exhausting hot air to the outside of the workshop through the exhaust pipe 10, the hot air can be prevented from being re-dissipated into the workshop, thus avoiding an increase in the workshop's ambient temperature, while ensuring that the workshop has enough air to meet the cooling requirements of the printed products.
[0046] like Figure 1 , Figure 5 as well as Figure 6 As shown, in an optional embodiment, the cooling device for the tinplate printed products further includes an air distribution plate 11; the air distribution plate 11 is fixedly mounted above the first side cabinet 1 and the second side cabinet 2, and the air distribution plate 11 is located between the upper and lower sides of the circulating chain 3; multiple air outlets 111 are spaced apart on the air distribution plate 11, and each air outlet 111 includes multiple air outlets 111 spaced apart along the length direction of the circulating chain 3; the cold air outlet 201 is located below the air distribution plate 11.
[0047] In the above embodiments, the air distribution plate 11 can divert and guide the cold air blown out of the cold air outlet 201. Specifically, when the cold air is discharged from the cold air outlet 201 below the air distribution plate 11, it will first come into contact with the air distribution plate 11, and then be evenly dispersed through the multiple air outlets 111 on the air distribution plate 11. This avoids the problem of excessively strong or weak local wind force caused by concentrated airflow when the cold air is blown out directly, thereby ensuring a consistent cooling effect for tinplate printed products.
[0048] like Figure 6 As shown, in an optional embodiment, the air distribution plate 11 is provided with air guide plates 12 between each row of air outlets 111; the length direction of the air guide plates is parallel to the length direction of the circulating chain 3. Specifically, the air guide plates 12 near the first side cabinet 1 are inclined towards the first side cabinet 1, while the air guide plates 12 near the second side cabinet 2 are inclined towards the second side cabinet 2, thereby further optimizing the distribution and guidance of the cold air and avoiding the problem of excessively strong or weak local wind force due to concentrated airflow when the cold air is blown out.
[0049] like Figure 2 As shown, as an extension, a curtain 13 is hung downwards on the top plate 5. The curtain 13 is located outside the first side cabinet 1. The curtain 13 can cooperate with the air guide box 7 to form a wind barrier, which can prevent some of the cold air from spreading outside the cooling device, so that the cold air acts more concentratedly on the surface of the tinplate printed products, providing a cooling effect for the printed products. As an example, the curtain 13 can be a transparent PVC curtain.
[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
