Description

Technical Field

[0001] The present invention belongs to the technical field of coating application, and specifically relates to an automated coating and drying treatment device and method. Background Art

[0002] In fields involving deck operations such as shipbuilding and maintenance, and the construction and operation of offshore engineering facilities, the coating of deck marking lines is an important task. Brushing is a common and relatively time-saving and labor-saving method. By connecting a paintbrush to a paint tank, the coating device can be manually pushed to move while the paintbrush draws on the deck.

[0003] When the existing coating device applies multiple marking lines simultaneously at a bend, due to the different coating speeds of the inner and outer circles of the bend while the paint supply speed is consistent, the coating effect is inconsistent, and it is easy to have a situation where the paint is too thick in the inner circle and there are defects in the outer circle.

[0004] Chinese Patent with the authorization announcement number CN218486455U discloses a wear-resistant and corrosion-resistant ship deck coating device. The motor drives the stirring shaft to rotate, which drives the disc to rotate, and then drives the stirring blades to rotate. Under the telescopic movement of the cylinder, the disc can be pushed to slide, driving the stirring blades to move, so that the stirring blades move and stir inside the stirring cylinder to improve the stirring effect of the paint; through the setting of rollers, it is convenient to push the coating device to move. Through the setting of brake blocks, the rollers can be braked and limited to avoid the problem of excessive movement of the coating device. Under the action of the card holes and the card blocks, the end plate can drive the brake blocks to be stably placed.

[0005] However, this technical solution still has at least the following defects: The above solution still cannot solve the coating defects or over-thick coating problems caused by the different lengths of the inner and outer circles of the marking lines at the bend during the coating process. In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides an automated coating and drying treatment device and method. By setting rollers on one side of the paintbrush and relying on the rolling of the rollers to provide the power for driving the paint delivery, the paint delivery speed is controlled by the rollers. When the rolling speed is relatively high, the paint delivery speed is increased to ensure that there are no coating defect problems with the paint. When the rolling speed is relatively low, the paint delivery speed is decreased to reduce the waste of paint.

[0018] As a preferred embodiment of the present invention, a drying unit is further included.

A heating sheet is installed at the bottom of the mounting shell, and flow guiding plates are installed at both ends of the heating sheet. A flow guiding pipe is installed inside the mounting shell, and a fan is installed at one end of the flow guiding pipe.

[0019] The present invention also discloses an automated coating and drying treatment method, and the automated coating and drying treatment method includes the following steps:

[0020] S1. During the movement, the rollers in the first coating mechanism and the second coating mechanism rotate on their own while in contact with the deck, and drive the first synchronous wheel to rotate. The first synchronous wheel drives the second synchronous wheel to rotate through a synchronous belt.

[0021] S2. The second synchronous wheel on the first coating mechanism drives the worm on the first pumping mechanism to rotate. The worm drives the worm wheel to rotate through meshing, and then the spiral plate rotates. At this time, the first pumping mechanism pumps the paint in the storage tank into the brush in the first coating mechanism through the first conduit and coats the deck.

[0022] S3. When the second synchronous wheel on the second coating mechanism rotates, it drives the third bevel gear to rotate through the folding plate. At the same time, the first coating mechanism drives the second bevel gear to rotate. The second bevel gear and the third bevel gear rotate in the same direction, causing the first bevel gear to revolve around the axis of the third bevel gear. The revolution speed of the first bevel gear is equal to half of the sum of the rotation speeds of the second bevel gear and the third bevel gear.

[0023] S4. When the first bevel gear revolves, it drives the movable block to rotate, and then the belt loop rotates. The belt loop drives the belt wheel to rotate through a belt. The belt wheel drives the worm in the second pumping mechanism to rotate, and then the spiral plate in the second pumping mechanism rotates. At this time, the paint in the storage tank enters the brush in the second coating mechanism through the second conduit and the third conduit under the action of the second pumping mechanism and coats the deck.

[0024] S5. When the brushing path encounters a smaller bend, the second coating mechanism located in the inner circle of the bend has a small moving radius, resulting in a low rotation speed of the roller, while the roller on the first coating mechanism in the middle still maintains a high rotation speed, enabling the first bevel gear to still maintain a considerable revolution speed, and then the spiral plate rotates and pumps the paint, avoiding insufficient pumping pressure caused by too low a speed of the spiral plate during use and being unable to transport the paint.

[0025] S6. The second coating mechanism located in the outer circle of the bend has a large moving radius, resulting in a high rotation speed of the roller, causing the rotation speed of the spiral plate in the second coating mechanism in the outer circle to increase, thereby increasing the transported paint and avoiding brushing defects caused by insufficient paint supply when the moving speed of the second coating mechanism in the outer circle increases.

[0026] S7. The painted paint is heated under the action of the heating sheet. At the same time, the fan blows the hot air generated by the heating sheet towards the deck. The escaping hot air diffuses under the action of the deflector and further dries the deck.

[0027] The present invention has the following beneficial effects compared with the prior art:

[0028] In the present invention, a roller is provided on one side of the brush, and the power for driving the paint delivery is provided by the rolling of the roller, so that the delivery speed of the paint is controlled by the roller. When the rolling speed is relatively high, the paint delivery speed is increased to ensure that there are no coating defects. When the rolling speed is relatively low, the paint delivery speed is decreased to reduce the waste of paint.

[0029] In the present invention, a speed control mechanism is provided to control the speed of driving the paint delivery, so as to avoid the situation that the paint delivery is not obvious due to the relatively low rolling speed of the inner ring when passing through a narrow bend, and thus coating defects occur.

[0051] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0052] Embodiment 1

[0053] As Figures 1 to 13 shown, an automated coating and drying treatment device includes a base frame 100. A coating unit is provided at the bottom of the base frame 100. The coating unit includes a first coating mechanism and a second coating mechanism. The second coating mechanism is located on both sides of the first coating mechanism. One end of the first coating mechanism and the second coating mechanism are respectively provided with a first pumping mechanism and a second pumping mechanism, and the first pumping mechanism and the second pumping mechanism have the same structure. The first pumping mechanism includes a sleeve 400, and a spiral plate 401 is installed inside the sleeve 400. The first pumping mechanism is used to supply materials to the first coating mechanism, and the second pumping mechanism is used to supply materials to the second coating mechanism;

[0054] A speed regulating mechanism is arranged between the first coating mechanism and the second coating mechanism, and the speed regulating mechanism is used to increase the lower limit of the rotation speed of the spiral plate 401 in the second pumping mechanism.

[0055] As Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 11 shown, in the specific implementation manner, the structures of the first coating mechanism and the second coating mechanism are the same. The first coating mechanism includes a mounting block 200. A roller 201 is installed at the bottom of the mounting block 200. A brush 202 is installed on one side of the mounting block 200. The sleeve 400 in the first pumping mechanism is embedded and connected to the brush 202. First transmission components are installed on both sides of the mounting block 200, and the first transmission components are used to transmit the power of the roller 201 to the speed regulating mechanism. In this setting, the top of the brush 202 can be set to a hollow state, which is convenient for the paint to penetrate into the brush 202 and move downward along the brush 202.

[0056] As Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 11 shown, further, the first transmission component includes a first synchronous pulley 203, a synchronous belt 204, and a second synchronous pulley 205, and the first synchronous pulley 203, the synchronous belt 204, and the second synchronous pulley 205 are meshed with each other. The first synchronous pulley 203 is connected to the roller 201;

[0057] The speed regulating mechanism includes a first bevel gear 307, a second bevel gear 308, and a third bevel gear 309, and the first bevel gear 307 is meshed with the second bevel gear 308 and the third bevel gear 309. The second bevel gear 308 is fixedly connected to the second synchronous pulley 205 in the first coating mechanism. A speed sensor 315 is installed at the bottom of the speed regulating mechanism, and the speed sensor 315 is used to measure the rotation speeds of the second bevel gear 308 and the third bevel gear 309. A distance adjusting mechanism is installed between the third bevel gear 309 and the second synchronous pulley 205 in the second coating mechanism, and the distance adjusting mechanism is used to adjust the distance between the second coating mechanism and the first coating mechanism. In this setting, when the roller 201 rotates on its own when it contacts the deck, it drives the first synchronous pulley 203 to rotate. The first synchronous pulley 203 drives the second synchronous pulley 205 to rotate through the synchronous belt 204. The first bevel gear 307 in the speed regulating mechanism is meshed with the second bevel gear 308 and the third bevel gear 309, so that the revolution speed of the first bevel gear 307 is half of the sum of the rotation speeds of the second bevel gear 308 and the third bevel gear 309.

[0058] Embodiment 2

[0059] As Figure 4 ,Figure 5 As shown, in the specific implementation manner, the distance adjustment mechanism includes a slide bar 314 fixedly installed at the bottom of the base frame 100. A fixed cylinder 300 is fixedly installed on the slide bar 314. A fixed plate 301 is fixedly installed on one side of the fixed cylinder 300. The third bevel gear 309 is rotatably connected to the fixed plate 301. A sleeve 313 is movably sleeved on the slide bar 314. A connecting plate 312 is fixedly installed on one side of the sleeve 313. A rotating disk 311 is rotatably installed on the connecting plate 312. A folding plate 310 is installed between the third bevel gear 309, the rotating disk 311, and the second synchronous wheel 205 of the second coating mechanism. In this setting, when the distance between the first coating mechanism and the second coating mechanism changes, the folding plate 310 undergoes an adaptive change to meet the distance change between the first coating mechanism and the second coating mechanism while ensuring the power transmission between the second synchronous wheel 205 and the third bevel gear 309.

[0060] As Figure 8 、 Figure 9 shown, further, the speed regulation mechanism further includes a fixed ring 303. A fixed block 302 is fixedly installed at the top of the fixed ring 303. The fixed block 302 is fixedly connected to the base frame 100. Symmetrically distributed movable blocks 304 are movably installed inside the fixed ring 303. A rotating shaft 306 is fixedly installed on the movable block 304. The first bevel gear 307 is movably connected to the rotating shaft 306. A second transmission assembly is provided between the speed regulation mechanism and the second pumping mechanism. The second transmission assembly includes a belt ring 305. The belt ring 305 is fixedly installed on the side surface of the movable block 304. A belt 502 is meshed with the belt ring 305. One end of the belt 502 is meshed with a belt pulley 501. The belt pulley 501 is rotatably installed on a support plate 500. The support plate 500 is fixedly connected to the base frame 100. In this setting, when the first bevel gear 307 revolves, it drives the movable block 304 to rotate, thereby causing the belt ring 305 to rotate. The belt ring 305 drives the belt pulley 501 to rotate through the belt 502.

[0061] As Figures 10 - 12 shown, further, one end of the spiral plate 401 inside the sleeve 400 is provided with a worm gear 402. A worm 403 is meshed with one side of the worm gear 402. The two ends of the worm 403 in the first pumping mechanism are rotatably connected to both sides of the mounting block 200 in the first coating mechanism and are fixedly connected to the second synchronous wheel 205 on its side surface. One end of the worm 403 in the second pumping mechanism is fixedly connected to the belt pulley 501, and both ends of the worm 403 are rotatably installed on a fixed frame 404. The top of the fixed frame 404 is fixedly installed at the bottom of the base frame 100. In this setting, the deceleration effect of the worm gear 402 and the worm 403 reduces the rotation speed of the spiral plate 401, preventing excessive rotation speed from causing waste of the coating material and playing a labor-saving role at the same time.

[0062] Example 3

[0063] As Figure 3 shown, in the specific implementation manner, a sliding mechanism is installed on the top of the base frame 100. The sliding mechanism includes an electric slide rail 101 and an electric slide table 102. Slide plates 103 are fixedly installed on both sides of the electric slide table 102. A first sliding component and a second sliding component are further provided on the top of the base frame 100. The first sliding component includes a first chute 105, and a first slider 104 is slidably installed inside the first chute 105. The mounting block 200 in the second coating mechanism is fixedly connected to the first slider 104. The second sliding component includes a second chute 107, and a second slider 106 is slidably installed inside the second chute 107. In this setting, by adjusting the electric slide rail 101 and the electric slide table 102, the first slider 104 and the second slider 106 can be driven to move.

[0064] As Figures 1 to 2 shown, further, an overhead plate 600 is fixedly installed on the top of the base frame 100. A storage tank 601 is installed on the top of the overhead plate 600. A first conduit 602 and a second conduit 603 are installed at the bottom of the storage tank 601. The first conduit 602 is connected to the sleeve 400 in the first pumping mechanism, and the second conduit 603 is connected to the sleeve 400 in the second pumping mechanism. A third conduit 604 is installed between the sleeve 400 in the second pumping mechanism and the brush 202 in the second coating mechanism. In this setting, the first pumping mechanism pumps the paint in the storage tank 601 into the brush 202 in the first coating mechanism through the first conduit 602, and the paint in the storage tank 601 enters the brush 202 in the second coating mechanism through the second conduit 603 and the third conduit 604 under the action of the second pumping mechanism.

[0065] Example 4

[0066] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 13 shown, an automatic coating and drying treatment device further includes a drying unit. Multiple groups of drying units are provided and are respectively aligned with the first coating mechanism and the second coating mechanism. The drying unit includes a mounting shell 700. The mounting shell 700 aligned with the first coating mechanism is fixedly connected to the base frame 100, and the mounting shell 700 aligned with the second coating mechanism is fixedly installed at the bottom of the second slider 106. A heating sheet 702 is installed at the bottom of the mounting shell 700, and flow guide plates 701 are installed at both ends of the heating sheet 702. A flow guide pipe 703 is installed inside the mounting shell 700, and a fan 704 is installed at one end of the flow guide pipe 703. In this setting, the painted paint is heated under the action of the heating sheet 702, and at the same time, the fan 704 blows the hot air generated by the heating sheet 702 towards the deck. The escaped hot air diffuses under the action of the flow guide plates 701 and further dries the deck.

[0067] This embodiment further includes adaptively adjusting the temperature of the heating sheet 702 in the drying unit through the rotational speed sensor 315. When the rotational speed sensor 315 detects that the rotational speed of the third bevel gear 309 decreases, it indicates that the second coating mechanism on this side is in the inner circle of the bend, and the moving speed of the roller 201 is slower, resulting in more paint accumulating on the deck. At this time, the rotational speed sensor 315 sends a signal to control the heating of the heating sheet 702 located in the inner circle of the bend to increase the drying speed.

[0068] This embodiment also provides an automated coating and drying processing method, which is implemented based on the above-mentioned automated coating and drying processing device. The implementation principle is as follows: During operation, the device as a whole is moved on the deck by manipulating the handle. During the movement, the rollers 201 in the first coating mechanism and the second coating mechanism rotate on their own while in contact with the deck, and drive the first synchronous wheel 203 to rotate. The first synchronous wheel 203 drives the second synchronous wheel 205 to rotate through the synchronous belt 204.

[0069] At this time, the second synchronous wheel 205 on the first coating mechanism drives the worm 403 on the first pumping mechanism to rotate. The worm 403 drives the worm wheel 402 to rotate through meshing, and then the spiral plate 401 rotates. At this time, the first pumping mechanism pumps the paint in the storage tank 601 into the brush 202 in the first coating mechanism through the first conduit 602 and coats the deck.

[0070] When the second synchronous wheel 205 on the second coating mechanism rotates, it drives the third bevel gear 309 to rotate through the folding plate 310. At the same time, the first coating mechanism drives the second bevel gear 308 to rotate. The co-rotation of the second bevel gear 308 and the third bevel gear 309 causes the first bevel gear 307 to revolve around the axis of the third bevel gear 309. The revolution speed of the first bevel gear 307 is equal to half of the sum of the rotation speeds of the second bevel gear 308 and the third bevel gear 309.

[0071] When the first bevel gear 307 revolves, it drives the movable block 304 to rotate, and then the belt loop 305 rotates. The belt loop 305 drives the belt pulley 501 to rotate through the belt 502. The belt pulley 501 drives the worm 403 in the second pumping mechanism to rotate, and then the spiral plate 401 in the second pumping mechanism rotates. At this time, the paint in the storage tank 601 enters the brush 202 of the second coating mechanism through the second conduit 603 and the third conduit 604 under the action of the second pumping mechanism and coats the deck.

[0072] When the brushing path encounters a smaller bend, the second coating mechanism located in the inner circle of the bend has a small moving radius, resulting in a low rotational speed of the roller 201. However, the roller 201 on the first coating mechanism in the middle still maintains a high rotational speed, enabling the first bevel gear 307 to still maintain a considerable rotational speed of revolution. As a result, the spiral plate 401 rotates and pumps in the coating, avoiding insufficient pumping pressure caused by too low a speed of the spiral plate 401 during use and thus being unable to transport the coating.

[0073] The second coating mechanism located in the outer circle of the bend has a large moving radius, resulting in a high rotational speed of the roller 201, causing the rotational speed of the spiral plate 401 in the second coating mechanism in the outer circle to increase, thereby increasing the amount of coating transported and avoiding brushing defects caused by insufficient coating supply when the moving speed of the second coating mechanism in the outer circle increases.

[0074] The coated paint is heated under the action of the heating sheet 702. At the same time, the fan 704 blows the hot air generated by the heating sheet 702 towards the deck, and the escaping hot air diffuses under the action of the deflector 701 and further dries the deck.

[0075] When it is necessary to brush marking lines at different distances, by adjusting the electric slide rail 101 and the electric slide table 102, the first slider 104 and the second slider 106 can be driven to move, and the second coating mechanism and the corresponding drying unit can be moved to complete the adjustment.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.

6. An automated coating and drying method, implemented based on the automated coating and drying device of claim 5, characterized in that: The automated coating and drying method comprises the following steps: S1. During the movement, the rollers (201) in the first coating mechanism and the second coating mechanism rotate while in contact with the deck, and drive the first synchronous wheel (203) to rotate. The first synchronous wheel (203) drives the second synchronous wheel (205) to rotate via the synchronous belt (204); S2, the second synchronous wheel (205) on the first coating mechanism drives the worm (403) on the first pumping mechanism to rotate, and the worm (403) drives the worm wheel (402) to rotate through meshing, thereby causing the spiral plate (401) to rotate. At this time, the first pumping mechanism pumps the paint in the storage box (601) into the brush (202) in the first coating mechanism through the first conduit (602), and the deck is coated; S3. When the second synchronous wheel (205) on the second coating mechanism rotates, the third bevel gear (309) is driven to rotate through the folding plate (310). At the same time, the first coating mechanism drives the second bevel gear (308) to rotate. The second bevel gear (308) and the third bevel gear (309) rotate in the same direction so that the first bevel gear (307) revolves around the axis of the third bevel gear (309).

When the brushing path encounters a smaller bend, the second coating mechanism located on the inner circle of the bend has a small moving radius, resulting in a low rotation speed of the roller (201), while the roller (201) on the first coating mechanism located in the middle still maintains a relatively high rotation speed, so that the first bevel gear (307) still maintains a revolution speed capable of rotating the spiral plate (401) and pumping in the paint; S6. The second coating mechanism located on the outer ring of the curve has a large moving radius, which results in a high rotation speed of the roller (201), which speeds up the rotation speed of the spiral plate (401) in the second coating mechanism on the outer ring, thereby increasing the amount of coating material transported.

8. The automated coating and drying method according to claim 7, characterized in that: The following steps are also included: S7. The applied paint is heated by the heating plate (702), and at the same time, the fan (704) blows the hot air generated by the heating plate (702) toward the deck.
