DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1 and Figure 5 As shown, a spraying machine comprises: a frame 1 and a first paint spraying mechanism and a second paint spraying mechanism symmetrically arranged on the frame 1, the first paint spraying mechanism and the second paint spraying mechanism have the same structure, a flipping mechanism is arranged between the first paint spraying mechanism and the second paint spraying mechanism structure, the first paint spraying mechanism comprises: a mounting frame plate 2 arranged on the frame 1, a paint sprayer 3 and a drying box 4 are arranged in sequence on the top surface of the mounting frame plate 2, a conveying assembly is arranged at the lower part of the mounting frame plate 2, and the conveying assembly comprises: two driving shafts 11 symmetrically arranged on the inner side of the mounting frame plate 2, a conveyor belt 12 is arranged on the outer side of the two driving shafts 11, a first driving device 13 is arranged on the outer side of the mounting frame plate 2, an output end of the first driving device 13 is connected to one of the driving shafts 11, a second driving device 22 is arranged on the outer side of the mounting frame plate 2, and an output end of the second driving device 22 is connected to the driving roller 6, two matching rollers 9 are symmetrically arranged on both sides of the driving roller 6, and the driving roller 6 and the two matching rollers 9 are matched and connected by a plurality of conveying strips 10.

[0031] The flipping mechanism comprises: a fixed frame 5 arranged between the two mounting frame plates 2, a driving roller 6 is arranged on the fixed frame 5, a plurality of rotating sleeves 7 are arranged in an array on the outer peripheral side of the driving roller 6, and a plurality of supporting rods 8 are arranged in an array on the outer peripheral side of the rotating sleeve 7. After the steel plate is sprayed by the first spraying mechanism, the conveyor belt 12 will convey the previous steel plate to the top of the conveying bar 10. When the steel plate in contact with one side contacts the rotating sleeve 7, the bottom surface of the steel plate contacts the top surface of the supporting rod 8, and the second driving device 22 drives the driving roller 6 to rotate a certain angle. At this time, one of the steel plates between the two adjacent supporting rods 8 will contact the conveying bar 10 on the other side of the rotating sleeve 7. When the rotating sleeve 7 rotates, it conveys the steel plate on the conveying bar 10 to the transmission belt on the second spraying mechanism for spraying. There is no need for manual intervention in flipping, which effectively improves the double-sided spraying efficiency of the steel plate.

[0032] like Figure 4 As shown, in a preferred embodiment of the utility model, the support rod 8 is arranged between two adjacent conveying bars 10, and the support rod 8 on each rotating sleeve 7 is on the same vertical projection plane, which can ensure that the support rods 8 on the three rotating sleeves 7 form a plane, thereby stably lifting the steel plate.

[0033] like Fig. 9 As shown, in a preferred embodiment of the utility model, an air inlet cavity 20 is symmetrically arranged on the upper part of the drying box 4, and the air inlet cavity 20 is connected to the exhaust port of a hot air blower (not shown in the figure) through an air supply pipe 21. An exhaust hole 23 is arranged on the inner side of the air inlet cavity 20. The exhaust port of the hot air blower conveys hot air to the air inlet cavity 20 through the air supply pipe 21, and then blows hot air to the surface of the steel plate through the exhaust hole 23, which can accelerate the drying of the paint, improve the spraying quality and remove dust from the surface of the steel plate.

[0034] In a preferred embodiment of the utility model, two exhaust cavities 24 are symmetrically arranged on both sides of the drying box 4, and exhaust holes 25 are arranged inside the exhaust cavities 24. The exhaust cavities 24 are connected to the return air duct 26, and the other end of the return air duct 26 is connected to the air inlet of the hot air blower. By symmetrically arranging two exhaust cavities 24 on both sides of the drying box 4 and exhaust holes 25 are arranged inside the exhaust cavities 24, after the hot air blows toward the steel plate, the exhaust holes 25 will re-transport the hot air to the air inlet of the hot air blower, and the hot air blower does not need to heat the cold air again for output, so that the hot air can be used multiple times, effectively saving heating energy.

[0035] like Figure 8 and Fig. 9As shown, two assembly plates 27 are symmetrically arranged directly below the drying box 4, and a plurality of pressing wheels 28 are arranged in an array on the two assembly plates 27. Through the assembly plates 27 arranged on the bottom surface of the drying box 4 and the pressing wheels 28 arranged on the bottom surface of the assembly plates 27, when the airflow in the drying box 4 blows toward the steel plate for dust removal, a certain pressing effect can be exerted on the steel plate, effectively preventing the steel plate from being blown up and causing deflection. On the other hand, the assembly plate 27 is connected to the drying box 4 through a plurality of supporting springs 29, and the middle part of the bottom surface of the assembly plate 27 is set to a flat surface, and the two ends of the bottom surface of the assembly plate 27 are set to an arc surface, which can ensure that the steel plate passes smoothly through the bottom surface of the assembly plate 27.

[0036] like Figure 2 and Figure 6 As shown, in a preferred embodiment of the utility model, a guide assembly is arranged on the inner side of the mounting frame plate 2. Through the guide assembly arranged on the inner side of the mounting frame plate 2, the guide assembly includes: a limit plate 15 arranged on the inner side of the mounting frame plate 2, the limit plate 15 is slidably connected to two guide plates 16, the two guide plates 16 are symmetrically arranged, and the bottom surfaces of the two guide plates 16 are slidably connected to the upper surface of the conveyor belt 12, and a transmission screw 17 is arranged on the inner side of the mounting frame plate 2. The transmission screw 17 is threadedly connected to the guide plate 16, and the transmission screw 17 is rotatably connected to the mounting frame plate 2, which can correct the position state of the steel plate on the conveyor belt 12, effectively prevent the steel plate from running off on the conveyor belt 12, and improve the spraying quality. Moreover, by rotating the transmission screw 17, the width of the guide assembly can be adjusted to adapt to steel plates of different sizes, so the application range is wider and the practicality is better.

[0037] like Figure 3 and Figure 7 As shown, in a preferred embodiment of the utility model, a plurality of positioning rubber belts 14 are arranged in an array on the outer peripheral side of the conveyor belt 12, and the positioning rubber belts 14 are arranged on the outer peripheral side of the conveyor belt 12. The positioning rubber belts 14 can increase the friction between the conveyor belt 12 and the steel plate, thereby improving the stability of the steel plate during transportation. On the other hand, an elastic plate 18 is arranged on the bottom surface of the limit plate 15, and a matching wheel 19 is arranged at the bottom end of the elastic plate 18, which can assist the elastic plate 18 and the matching wheel 19 in pressing the steel plate, thereby playing a certain role in correcting the conveying route.

[0038] When the utility model is used, the steel plate is placed on the conveyor belt 12 on the first paint spraying mechanism. After the steel plate is sprayed by the paint sprayer 3 on the first paint spraying mechanism, the conveyor belt 12 will be used to transport the previous steel plate to the top of the conveying strip 10. When the steel plate on one side contacts the rotating sleeve 7, the bottom surface of the steel plate contacts the top surface of the support rod 8. The second driving device 22 drives the driving roller 6 to rotate a certain angle. At this time, one of the steel plates between the two adjacent support rods 8 will contact the conveying strip 10 on the other side of the rotating sleeve 7, that is, when a steel plate on the conveying strip 10 is lifted up by the support rod 8, the steel plate on the other side of the rotating sleeve 7 will be placed on the conveying strip 10. The rotating sleeve 7 rotates to transport the steel plate on the conveying strip 10 to the transmission belt on the second paint spraying mechanism for spraying, drying and dust removal, thereby completing the double-sided spraying process.

[0039] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
