DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings of the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary, for explaining the utility model, and cannot be understood as limiting the utility model.

[0030] The embodiments will be described below according to the overall structure of the utility model.

[0031] A kind of color coated steel coil surface brushing baking device, as Figures 1-5 ​​As shown, including the shell 1, the shell 1 is provided with a material inlet 7 at one end, so that the steel coil can enter the shell 1 through the material inlet 7, while the other end of the shell 1 is provided with a discharge port 9, so that the baked steel coil can be discharged from the shell 1 through the discharge port 9.

[0032] Then both sides of the shell 1 are fixedly connected with connecting blocks 2, each of which is provided with a cavity 3, and the top of the shell 1 is provided with a baking device body 5, and the two ends of the baking device body 5 are connected with the cavities 3 in the connecting blocks 2 through pipes 6, so that the hot air generated by the baking device body 5 can be transported into the cavities 3 through the pipes 6, thereby providing a source of hot air for the connecting blocks 2, facilitating the baking of the steel coil. A group of connecting blocks 2 adjacent surfaces are provided with a plurality of first air outlets 4 connected with the cavities 3, so that the hot air in the connecting blocks 2 can be discharged into the shell 1 through the first air outlets 4, facilitating the provision of hot air for the steel coil in the shell 1. Both sides of the shell 1 are provided with connecting pieces 15 matched with the connecting blocks 2, and the connecting pieces 15 are provided with a plurality of air inlets 16 on the side close to the connecting blocks 2. The shell 1 is fixedly connected with a fixed block 17 on the side close to the material inlet 7, and the top of the fixed block 17 is provided with a plurality of second air outlets 18. The two sides of the fixed block 17 are connected with the corresponding connecting pieces 15 through connecting pipes 19, so that part of the hot air in the shell 1 can enter the connecting pieces 15 through the air inlets 16, and then be transported into the fixed block 17 through the connecting pipes 19, so that it can be discharged through the second air outlets 18 on the top of the fixed block 17. It is convenient to pre-bake the bottom of the steel coil when it enters the shell 1, so that the coating on the bottom of the steel coil is pre-solidified. When the coated steel coil enters the shell 1, it can contact the bottom of the material inlet 7, thereby supporting the steel coil and facilitating its stable entry into the shell 1 for omnidirectional baking. Since the bottom of the steel coil has been pre-baked, contacting the bottom of the material inlet 7 will not damage the coating, which helps to avoid damage to the coating due to friction, ensuring the integrity and aesthetics of the coating on the surface of the color-coated steel coil and improving the yield of the product.

[0033] The connecting block 2 is provided in an inverted "L" shape, which better fits the inside of the shell 1, and because the connecting block 2 is located on both sides of the shell 1, it can be located on both sides of the steel coil, facilitating better baking of the steel coil and improving the baking effect.

[0034] The connection between the connecting pipe 19 and the shell 1 is achieved through the fixing ring 20, which can increase the stability of the connecting pipe 19, so that the connecting pipe 19 can stably transport part of the hot air in the shell 1, thereby providing a source of hot air for pre-baking the steel coil. The fixing block 17 is connected to the shell 1 through a group of inclined rods 21, which increases the connection between the fixing block 17 and the shell 1, thereby improving the stability of the fixing block 17 and allowing the hot air discharged from the second air outlet 18 to be sprayed onto the surface of the steel coil, which helps to better pre-bake the bottom of the steel coil.

[0035] The first roller 8 is rotatably connected to the bottom of the inlet 7, which can reduce the friction between the steel coil and the inlet 7, thereby better ensuring the completeness of the coating on the bottom of the steel coil and avoiding damage caused by excessive friction. The second roller 10 is rotatably connected to the top and bottom of the outlet 9 through the shaft 11, so that the steel coil can pass through the middle of a group of second rollers 10 when it is discharged from the shell 1. One end of each shaft 11 is movably penetrated through one side of the shell 1 and extends to the outside to be connected with a gear 12. A group of gears 12 are engaged with each other. The fixed plate 14 is fixedly connected to one side of the shell 1, and the motor 13 is engaged with the shaft 11 at the top of the fixed plate 14. The output end of the motor 13 is connected to one end of the shaft 11. Then, the motor 13 is started to drive a group of second rollers 10 to rotate, thereby providing driving force for the movement of the steel coil, which can better discharge the baked steel coil from the shell 1. The speed of the motor 13 can also be adjusted to control the speed of the steel coil discharge, thereby better baking the steel coil.

[0036] Therefore, when using the device, the surface of the steel coil is first coated with a coating, and then the coated steel coil is transported to one end of the inlet 7. The hot air discharged from the second air outlet 18 can be used to preliminarily bake and solidify the bottom of the steel coil. When the steel coil enters the shell 1, its bottom can be in contact with the bottom of the inlet 7, thereby serving as a support to stably enter the shell 1 for omnidirectional baking. Since the bottom of the steel coil is pre-baked, the contact between the bottom of the steel coil and the bottom of the inlet 7 will not cause damage to the coating, which helps to avoid damage to the coating due to friction, thereby ensuring the integrity and aesthetics of the coating on the surface of the color-coated steel coil and improving the yield of the product.
