[0025] See also Figure 1-Figure 6 , the utility model provides a technical solution:
[0026] See also Figure 1-Figure 6 As shown, a device for drying carton convenient for heat circulation comprises a drying box 1 and a carton 2, wherein an electric heating wire 22 is arranged inside the drying box 1, a servo motor 6 is fixedly mounted on the inner top wall of the drying box 1, a driving end of the servo motor 6 is connected to a support rod 10, a rotating rod 21 is arranged below the support rod 10, the bottom end of the rotating rod 21 is rotatably connected to the inner bottom wall of the drying box 1, a U-shaped connecting rod 7 is fixedly connected between the support rod 10 and the rotating rod 21, impellers 9 are fixedly connected to the outer walls of the support rod 10 and the rotating rod 21, an air collecting duct 11 is arranged on the periphery of the support rod 10, the bottom end of the air collecting duct 11 is located inside the carton 2, the carton 2 is located between two impellers 9, the electric heating wire 22 is located below the carton 2, and the electric heating wire 22 is located above one of the impellers 9.
[0027] The servo motor 6 drives the support rod 10 to rotate, and the support rod 10 drives the U-shaped connecting rod 7 and the rotating rod 21 to rotate together, so that the two impellers 9 rotate together. After the lower impeller 9 rotates, it will blow air upwards. After the wind blows through the heating wire 22, the heating wire 22 will heat the wind. After the wind becomes hot, it blows through the carton 2, which has the effect of heating the periphery of the carton 2. After the upper impeller 9 rotates, it generates suction upwards. After the hot air floats to the top of the air collecting pipe 11, it will be sucked into the inside of the air collecting pipe 11 by the impeller 9 in the air collecting pipe 11, and then the hot air sucked into the air collecting pipe 11 will be blown into the inside of the carton 2 through the bottom of the air collecting pipe 11, thereby realizing multi-directional drying of the carton 2.
[0028] See also Figure 3 and Figure 5 A fixing block 16 is fixedly installed on the outer wall of the U-shaped connecting rod 7, and a fan blade 17 is rotatably connected to the outer wall of the fixing block 16, and the fan blade 17 corresponds to the carton 2.
[0029] When the U-shaped connecting rod 7 rotates around the carton 2, it will drive the fan blades 17 to rotate along the carton 2. The U-shaped connecting rod 7 blows air to the outer wall of the carton 2, so that the hot air blows more evenly on the outer wall of the carton 2. The fixing block 16 is used to fix the fan blades 17 on the U-shaped connecting rod 7.
[0030] See also Figure 2-Figure 4 A fixing frame 14 is provided inside the drying box 1 , and a plurality of through holes 15 are opened in the fixing frame 14 . A plurality of partitions 23 are fixedly installed on the inner wall of the fixing frame 14 , and the carton 2 is placed on top of the plurality of partitions 23 .
[0031] The fixing frame 14 and the partitions 23 support the carton 2, and the hot air can be blown to the bottom of the carton 2 through the gaps between the multiple partitions 23, and the hot air can also be blown to the outer wall of the carton 2 through the multiple through holes 15 to prevent the fixing frame 14 from blocking the carton 2 and causing uneven drying of the carton 2.
[0032] See also Figure 2-Figure 6 A fixing ring 8 is fixedly installed on the inner wall of the drying box 1, a circular support plate 19 is arranged inside the fixing ring 8, a swivel 20 is rotatably connected between the fixing ring 8 and the circular support plate 19, the heating wire 22 is located inside the circular support plate 19, and the U-shaped connecting rod 7 is rotatably connected to the swivel 20.
[0033] The fixing ring 8 is fixed inside the drying box 1, and the circular support plate 19 is connected to the fixing ring 8 through a swivel 20, so that the fixing frame 14 and the carton 2 can be supported by the circular support plate 19, and the swivel 20 can rotate along the circular support plate 19 and the fixing ring 8 to avoid hindering the rotation of the U-shaped connecting rod 7.
[0034] See also Figure 6 The fixing ring 8 is provided with an annular groove 25 , the circular support plate 19 is provided with a slide groove 24 , the rotating ring 20 is located between the slide groove 24 and the annular groove 25 , and the rotating ring 20 is rotatably connected with the slide groove 24 and the annular groove 25 .
[0035] When the U-shaped connecting rod 7 rotates with the swivel 20, the swivel 20 will rotate along the slide groove 24 and the annular groove 25, and the swivel 20 is inserted into the slide groove 24 and the annular groove 25, so that the swivel 20 and the circular support plate 19 will not fall off.
[0036] See also Figure 2-Figure 4A plurality of support rods 13 are installed on the top of the circular support plate 19 , and a fixing frame 14 is fixedly installed on the top of the plurality of support rods 13 .
[0037] A plurality of supporting rods 13 hold up the fixing frame 14 and allow the bottom of the carton 2 to be suspended in the air, so that hot air can be blown to the bottom of the carton 2 through the bottom of the fixing frame 14 .
[0038] See also Figure 2-Figure 3 A nano sponge 12 is fixedly installed on the inner wall of the air collecting pipe 11, and the support rod 10 is plugged into the nano sponge 12. A wind shield 3 is arranged above the air collecting pipe 11, and the support rod 10 is plugged into the wind shield 3. Two mounting rods 18 are fixedly installed on the top of the air collecting pipe 11, and the top of the mounting rod 18 is fixedly connected to the inner top wall of the wind shield 3.
[0039] After the hot air dries the carton 2, the moisture in the carton 2 will become gaseous after being heated, and then the water vapor will be sucked into the air collecting pipe 11 together with the hot air. When the water vapor contacts the nano sponge 12, the water will remain in the nano sponge 12, and the hot air will continue to float into the carton 2 to prevent the water from being transmitted into the carton 2. The wind shield 3 blocks the hot air and water vapor. When the hot air continues to move upward and hits the wind shield 3, the hot air will gather at the top of the air collecting pipe 11, making it convenient for the impeller 9 to absorb the hot air.
[0040] See also Figure 2-Figure 3 Two fixing rods 4 are fixedly connected between the top of the circular support plate 19 and the bottom of the wind shield 3, a fixing plate 5 is fixedly installed on the inner wall of the drying box 1, the support rod 10 is rotatably connected to the fixing plate 5, and the servo motor 6 is installed on the top of the fixing plate 5.
[0041] The fixing rod 4 supports the windshield 3 so that the windshield 3 is fixed on the circular support plate 19 . The fixing plate 5 supports the servo motor 6 and separates the servo motor 6 from the hot air to prevent the hot air below from affecting the servo motor 6 .
[0042] Working principle:
[0043] The servo motor 6 drives the support rod 10 to rotate, and the support rod 10 drives the U-shaped connecting rod 7 and the rotating rod 21 to rotate together, so that the two impellers 9 rotate together. After the lower impeller 9 rotates, it will blow air upwards. After the wind blows through the heating wire 22, the heating wire 22 will heat the wind. After the wind becomes hot, it blows through the carton 2, which has the effect of heating the periphery of the carton 2. After the upper impeller 9 rotates, it generates suction upwards. After the hot air floats to the top of the air collecting pipe 11, it will be sucked into the inside of the air collecting pipe 11 by the impeller 9 in the air collecting pipe 11, and then the hot air sucked into the air collecting pipe 11 will be blown into the inside of the carton 2 through the bottom of the air collecting pipe 11, thereby realizing multi-directional drying of the carton 2.
[0044] When the U-shaped connecting rod 7 rotates around the carton 2, it will drive the fan blades 17 to rotate along the carton 2. The U-shaped connecting rod 7 blows air to the outer wall of the carton 2, so that the hot air blows more evenly on the outer wall of the carton 2. The fixing block 16 is used to fix the fan blades 17 on the U-shaped connecting rod 7.
