Technical Field

[0001] The utility model relates to the technical field of can production, in particular to a product uniform heating mechanism in a can making and drying furnace. Background Art

[0002] The can (metal beverage container) was invented in 1959 by Ernie C. Fraze of DRT in Detroit, Ohio, USA. The can is made by processing the can lid material into a rivet, then adding a pull ring, riveting it, and adding appropriate notches to form a complete lid. During the can manufacturing process, the bottom of the can needs to be painted.

[0003] In the prior art, the Chinese patent document with application number: 201821902202.5 discloses a two-piece can drying device, including a bottom plate, the upper surface wall of the bottom plate is fixedly connected to the lower surface wall of the first support plate, the number of the first support plates is two, and the opposite surfaces of the two first support plates are rotatably connected to the first roller, the upper surface wall of the bottom plate is fixedly connected to the lower surface wall of the second support plate, the number of the second support plates is two, and the opposite surfaces of the two second support plates are rotatably connected to the second roller, one end of the second roller is sleeved with a driven wheel, and the driven wheel is connected to the driving wheel through a belt. The utility model is provided with a motor, a fan blade, a heating plate, a conveyor belt, a motor, a driven wheel, a driving wheel, a box body, a first roller, a second roller, a belt and a can body. The box body has a sealed structure to improve the drying efficiency. The can bodies are transported by the conveyor belt, can be mass-produced, and the production efficiency is improved.

[0004] However, in the above technical solution, since the motor is arranged inside the drying box, and the temperature inside the drying box is relatively high, the motor will be damaged by overheating for a long time. Secondly, the inlet and outlet ports on both sides of the drying box do not have a sealing structure, and heat will be lost to the outside of the drying box, thereby reducing the drying efficiency and effect of the cans. For this reason, we propose a product uniform heating mechanism in the can making oven to solve the above problems. Utility Model Content

[0033] A heating assembly, comprising: four motors 7, four fans 8, and a heating plate 9. The four motors 7 are fixedly mounted on the top of the drying box 2. The output shafts of the motors 7 pass through the top of the drying box 2 and are rotatably connected to the drying box 2. The fans 8 are fixedly mounted on the output shafts of the corresponding motors 7. The heating plate 9 is fixedly mounted inside the drying box 2.

[0034] The heat preservation component is arranged on the drying box 2 and is used to intercept heat from the inlet and outlet of the drying box 2.

[0035] By means of the above structure: by starting the four motors 7, the four fans 8 can be driven to rotate. At this time, the heating plate 9 is energized to release heat, and then the fan 8 can blow the heat downward to form hot air flowing inside the drying box 2, so that the cans entering the drying box 2 can be dried. Here, by arranging the motor 7 outside the drying box 2, the heat can be prevented from damaging the motor 7, which facilitates the heat dissipation of the motor 7 and realizes efficient protection of the motor 7.

[0036] As a preferred solution of the present invention, an observation window 4 is provided on the front side of the box door 3 , and the observation window 4 can facilitate personnel to observe the drying conditions of the cans entering the drying box 2 .

[0037] As a preferred solution of the present invention, through holes are provided on the left inner wall and the right inner wall of the drying box 2, and the left and right ends of the conveyor belt 5 respectively pass through the two through holes and cooperate with the through holes. By providing the through holes, the conveyor belt 5 can be easily installed and the cans can be easily moved in and out of the drying box 2.

[0038] As a preferred solution of the present invention, the insulation component includes two protective boxes 10 and two ducts 11. The two protective boxes 10 are fixedly connected to the top of the base plate 1, and the ends of the two protective boxes 10 close to each other are respectively fixedly connected to the left and right sides of the drying box 2. The protective boxes 10 are connected to the corresponding through holes. The two protective boxes 10 are respectively sleeved on the left and right ends of the conveyor belt 5. The bottom end of the duct 11 is fixedly connected to the top of the corresponding protective box 10, and the top end of the two ducts 11 is respectively fixedly connected to the left and right sides of the drying box 2. By setting the protective box 10, the through holes on both sides of the drying box 2 are wrapped, and the hot air can be drained through the duct 11 to avoid heat loss to the outside of the drying box 2, and the drying efficiency and effect of the cans can be guaranteed.

[0042] The working principle of the present invention is as follows: when in use, first connect the conveyor belt 5, the motor 7, the fan 8 and the heating plate 9 to the external power supply, then place the cans on the top of the conveyor belt 5 in turn through the right protective box 10, and then start the conveyor belt 5 to transport the cans to the inside of the drying box 2. At this time, by starting the four motors 7, the four fans 8 can be driven to rotate. At this time, the heating plate 9 is energized to release heat, and then the fan 8 can blow the heat downward to form hot air flowing inside the drying box 2, so that the cans entering the drying box 2 can be dried. Here, by arranging the motor 7 outside the drying box 2, the heat can be prevented from damaging the motor 7, which facilitates the heat dissipation of the motor 7 and realizes efficient protection of the motor 7. In addition, by arranging the protective box 10 to wrap the through holes on both sides of the drying box 2, and then by arranging the guide plate 12, the hot air inside the drying box 2 can be guided to the inside of the protective box 10 through the duct 11, so that a hot air wall can be formed inside the two protective boxes 10, thereby preventing heat from being lost to the outside of the drying box 2 and ensuring the drying efficiency and effect of the cans.
