[0002] Rolling is a process of passing a metal material between one or more pairs of rotating rollers to reduce its thickness and increase its length or width at the same time. For non-ferrous metals (such as copper, aluminum and their alloys), rolling can improve the mechanical properties of the material, such as strength and hardness, and can produce very thin and uniform products. Spraying refers to the technology of using specific equipment to atomize paint or other surface treatment agents and then spray them onto the surface of the workpiece to form a protective film or decorative layer.

[0019] 1. This device is equipped with a flipping mechanism.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] The present invention will be further described below in conjunction with the embodiments.

[0039] See also Figure 1 , Figure 2 and Figure 4The flipping mechanism 2 includes a bracket 21 fixedly connected to the upper surface of the base 1, the bracket 21 is symmetrically fixedly connected to a placing table 22, a fixed plate 23 is fixedly connected to the middle of the bracket 21, a rotating shaft 24 is horizontally rotatably connected to the middle of the fixed plate 23, a plurality of levers 25 are fixedly connected to the side of the rotating shaft 24 at equal intervals, the two placing tables 22 are provided with a plurality of notches 26, the notches 26 and the levers 25 match each other, a first motor 27 is fixedly connected to the side of the fixed plate 23, the output end of the first motor 27 is fixedly connected to one end of the rotating shaft 24, and a limit assembly 28 for preventing the metal sheet from deflecting when flipping is arranged on the upper surface of the lever 25.

[0040] During specific work, when spraying the rolled metal sheet, first place the metal sheet on the upper surface of the right placement table 22, so that the left side of the metal sheet contacts the limiting protrusion of the right placement table 22, and then start the spraying mechanism 3 to spray the upper surface of the metal sheet. After the spraying is completed, the first motor 27 drives the rotating shaft 24 to rotate clockwise, so that the lever 25 rotates clockwise to the top of the metal sheet on the right placement table 22, and then the limiting assembly 28 is used to clamp the side of the metal sheet. Finally, the first motor 27 drives the rotating shaft 24 to rotate counterclockwise again. At this time, the rotating shaft 24 drives the metal sheet to flip from the right placement table 22 to the left placement table 22 through the lever 25, so that the metal sheet can be flipped 180 degrees, and the unsprayed lower surface is flipped upward.

[0041] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The limiting assembly 28 includes a receiving groove 283 opened on the upper surface of the lever 25, a screw rod 284 is rotatably connected inside the receiving groove 283, a movable tooth 282 is threadedly connected to the outer side of the screw rod 284, the movable tooth 282 is slidably connected to the lever 25, and a fixed tooth 281 is fixedly connected to the end of the lever 25 away from the rotating shaft 24.

[0042] The screw 284 extends from one end away from the fixed tooth 281 to the inside of the cavity of the rotating shaft 24, and the extended end of the screw 284 is fixedly connected to a worm gear 285. The cavity of the rotating shaft 24 is rotatably connected to a transmission shaft 287, and the outside of the transmission shaft 287 is fixedly connected to multiple worms 286. The worms 286 correspond to the worm gears 285 one by one, and the worms 286 are meshed with the worm gears 285. The rotating shaft 24 is fixedly connected to one end away from the first motor 27 with a second motor 288, and the output end of the second motor 288 is fixedly connected to the transmission shaft 287.

[0043] During specific operation, the first motor 27 drives the rotating shaft 24 to rotate clockwise, so that the lever 25 rotates clockwise to above the metal plate on the right side placement table 22. At this time, the fixed teeth 281 and the movable teeth 282 are inserted into the notch 26 of the right side placement table 22, and then the second motor 288 drives the transmission shaft 287 to rotate. The transmission shaft 287 drives the worm 286 and the worm wheel 285 to drive the screw 284 to rotate. The rotating screw 284 drives the movable teeth 282 to move in the direction close to the fixed teeth 281, so that the movable teeth 282 and the fixed teeth 281 are clamped on both sides of the metal plate, thereby fixing the metal plate.

[0044] After the first motor 27 drives the rotating shaft 24 to rotate counterclockwise again, the rotating shaft 24 drives the metal sheet to flip from the right placement table 22 to the left placement table 22 through the lever 25. At this time, the fixed tooth 281 is completely dropped into the notch 26 of the left placement table 22, and the flipped metal sheet is sprayed through the spraying mechanism 3. Then, the transmission shaft 287 is driven to rotate by the second motor 288 again, and the transmission shaft 287 drives the worm 286 and the worm wheel 285 to drive the screw 284 to rotate. The rotating screw 284 drives the mobile tooth 282 to move in the direction close to the fixed tooth 281. Since the fixed tooth 281 is completely dropped into the notch 26 of the left placement table 22, the mobile tooth 282 that moves in this way can push the metal sheet off the left placement table 22 after spraying. Finally, the mobile tooth 282 is moved in the direction away from the fixed tooth 281 through the screw 284, so that the distance between the mobile tooth 282 and the fixed tooth 281 is greater than the width of the metal sheet.

[0045] See also Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 The spraying mechanism 3 includes a U-shaped frame 31 arranged on the upper surface of the base 1, a mounting plate 32 is arranged at the bottom of the U-shaped frame 31, connecting shafts 35 are fixedly connected at both ends of the mounting plate 32, and the two connecting shafts 35 are rotatably connected to the U-shaped frame 31, a plurality of atomizing nozzles 33 are fixedly connected to the bottom of the mounting plate 32, and a storage tank 34 is fixedly connected to the lower surface of the base 1. The storage tank 34 and the plurality of atomizing nozzles 33 are interconnected through a hose, and a stirring component 5 is arranged inside the storage tank 34 to prevent paint precipitation.

[0046] The spraying mechanism 3 also includes a connecting rod 36 arranged at one end of the connecting shaft 35, and the end of the connecting rod 36 away from the center point is fixedly connected to the connecting shaft 35, a slide groove 37 is provided on the outside of the connecting rod 36, and a slider 38 is slidably connected inside the slide groove 37, and a third motor 39 is fixedly connected to the outside of the U-shaped frame 31, and a disc 40 is fixedly connected to the output end of the third motor 39, and a side of the disc 40 away from the output end of the third motor 39 is fixedly connected to the slider 38, the disc 40 is concentrically connected to the output end of the third motor 39, and the disc 40 is eccentrically connected to the slider 38.

[0047] During specific operation, when spraying the metal sheet on the placement table 22, the paint in the storage tank 34 is transported to the atomizing nozzle 33 along the hose through the air pump, and at the same time, the disc 40 is driven to rotate by the third motor 39, and the disc 40 drives the slider 38 to rotate synchronously. Since the slider 38 slides in the slide groove 37, the third motor 39 drives the connecting rod 36 to swing back and forth, and the connecting rod 36 drives the atomizing nozzle 33 on the mounting plate 32 to swing back and forth synchronously through the connecting shaft 35, so that the paint can be evenly sprayed on the surface of the metal sheet, avoiding the situation of local excessive thickness or thinness, and reducing unnecessary overlapping spraying.

[0048] See also Figure 3 and Figure 8 The stirring assembly 5 includes a rotating shaft 51 horizontally rotatably connected to the inside of the storage tank 34, and a plurality of blades 52 are symmetrically fixedly connected to the outside of the rotating shaft 51.

[0049] A gear 53 is fixedly connected to one end of the rotating shaft 51 . A rack 54 is meshed above the gear 53 . The rack 54 is fixedly connected to the U-shaped frame 31 .

[0050] During specific operation, when the U-shaped frame 31 moves horizontally on the base 1, it drives the gear 53 to rotate through the rack 54, and the rotating gear 53 drives the rotating shaft 51 to rotate. When the rotating shaft 51 rotates, it drives the blades 52 to stir the paint in the storage tank 34. Stirring can help disperse the particles in the paint and prevent them from agglomerating, thereby ensuring the fluidity of the paint.

[0051] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The direction switching mechanism 6 includes a driving wheel 61 rotatably sleeved on the outside of the rotating shaft 24, a steel cable 63 is fixedly connected to the outside of the driving wheel 61, and one end of the steel cable 63 away from the driving wheel 61 is fixedly connected to the U-shaped frame 31. A guide wheel 62 is fixedly connected to the upper surface of the base 1, and the middle of the steel cable 63 passes through the guide wheel 62. A rotating shaft 24 is arranged on the side of the driving wheel 61. The rotating shaft 24 can drive the driving wheel 61 to rotate synchronously only when it rotates in one direction. The connecting component 66.

[0052] The direction switching mechanism 6 also includes a slide rail 64 fixedly connected to the upper surface of the base 1, the slide rail 64 is slidably connected to the U-shaped frame 31, and a return spring 65 is also provided on the upper surface of the base 1, one end of the return spring 65 is fixedly connected to the protrusion on the upper surface of the base 1, and the other end of the return spring 65 is fixedly connected to the bottom of the U-shaped frame 31.

[0053] During specific operation, when the rotating shaft 24 rotates counterclockwise, it drives the driving wheel 61 to rotate synchronously. At this time, the driving wheel 61 reels the steel cable 63 to the outside of the driving wheel 61, and the reeled steel cable 63 moves the U-shaped frame 31 from the right side to above the left placement table 22 along the slide rail 64. Then the spraying mechanism 3 sprays the metal sheet on the left placement table 22. During the movement of the U-shaped frame 31 to the left, the reset spring 65 is compressed and accumulates force.

[0054] See also Figure 6 and Figure 7 The connecting component 66 includes a groove 661 opened on the side of the driving wheel 61, an annular ratchet 662 is fixedly connected inside the groove 661, a pawl 663 is rotatably connected to the outside of the rotating shaft 24, the pawl 663 is engaged with the ratchet 662, a metal spring 664 is fixedly connected inside the groove 661, and the metal spring 664 is tightly attached to the side of the pawl 663.

[0055] During specific operation, when the rotating shaft 24 rotates clockwise, the rotating shaft 24 drives the pawl 663 to rotate synchronously clockwise. When pushed by the elastic force of the metal spring 664, the pawl 663 is always engaged with the ratchet 662. At this time, the rotating shaft 24 will not drive the driving wheel 61 to rotate synchronously.

[0056] When the rotating shaft 24 rotates counterclockwise, the pawl 663 and the ratchet 662 are in a meshing state. Therefore, the rotating shaft 24 drives the driving wheel 61 to rotate counterclockwise synchronously. The counterclockwise rotating driving wheel 61 reels the steel cable 63 to the outside of the driving wheel 61, and the reeled steel cable 63 moves the U-shaped frame 31 along the slide rail 64 from the right side to above the placement table 22 on the left side. After spraying is completed, the pawl 663 is toggled to release the meshing state of the pawl 663 and the ratchet 662. At this time, the compressed and force-accumulating return spring 65 pushes the U-shaped frame 31 to move to the right side along the slide rail 64. When the U-shaped frame 31 moves to the right side, the driving wheel 61 is pulled to rotate outside the rotating shaft 24 by the steel cable 63. When the U-shaped frame 31 moves to the right side, the pawl 663 is released so that the pawl 663 resumes the meshing state with the ratchet 662. Finally, a new metal sheet to be sprayed is transported to the placement table 22 on the right side for spraying through the conveyor belt.

[0057] Working principle:

[0058] First, the metal sheet on the right placement table 22 is sprayed by the spraying mechanism 3. After spraying, the metal sheet is flipped over to the left placement table 22 by the flipping mechanism 2. At the same time, the spraying mechanism 3 is driven to move synchronously to the top of the left placement table 22 by the direction switching mechanism 6. Then the spraying mechanism 3 sprays the metal sheet on the left placement table 22 again. After the spraying is completed, the moving tooth 282 is controlled to move in the direction close to the fixed tooth 281. Since the fixed tooth 281 is completely dropped into the notch 26 of the left placement table 22, the moving tooth 282 that moves in this way can push the metal sheet off the left placement table 22 after the spraying is completed, and then the pawl 663 is moved to release the meshing state of the pawl 663 and the ratchet 662. At this time, the compressed and force-accumulating return spring 65 pushes the U-shaped frame 31 to move to the right along the slide rail 64. Finally, a new metal sheet to be sprayed is conveyed to the right placement table 22 for spraying by the conveyor belt.
