Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a spraying device capable of uniformly spraying paint. Background Technology

[0002] Marine pipeline coating is a key process for protecting marine equipment. By spraying corrosion-resistant materials such as epoxy resin and polyurethane, a dense protective layer is formed on the pipeline surface, effectively resisting the erosion of seawater, salt spray, and chemical media. Surface treatment and primer application are required before coating to ensure adhesion, while the topcoat provides long-lasting protection and color identification. This technology extends pipeline lifespan, reduces maintenance costs, and ensures safe ship operation, making it an indispensable and crucial aspect of marine engineering.

[0003] Chinese patent CN205599404U discloses a pipeline anti-corrosion spraying device, including a storage tank. The top left and right sides of the storage tank are vertically fixed to the same inverted concave frame. A first electric push rod is vertically fixed downwards at the top center of the inverted concave frame. The lower end of the push rod of the first electric push rod is vertically fixed to the top center of a spray pipe. Multiple equidistant atomizing nozzles are vertically fixed downwards at the bottom of the spray pipe. This spraying device uses a speed-regulating motor that rotates slowly. A stirring rod on the drive shaft stirs the anti-corrosion material in the storage tank, preventing sedimentation or stratification. Furthermore, the drive pulley on the drive shaft of the speed-regulating motor drives a follower pulley to rotate via a belt. The follower pulley, through a bearing, drives a movable rod to rotate, thereby causing the pipe to rotate at a low speed, ensuring the completeness and efficiency of the subsequent spraying process.

[0004] The spraying device described in the aforementioned patent document uses second electric push rods rotatably mounted on both sides of an inverted concave frame, with the movable end of the pipe clamp fixed at the output end of the second electric push rod. During operation, the second electric push rod drives the movable end of the pipe clamp to move horizontally, thus clamping both ends of the pipe. However, existing pipe clamping devices cannot effectively fix the ends of pipes with large diameters. Therefore, a spraying device capable of uniformly spraying paint is proposed. Utility Model Content

[0005] To address the aforementioned problems, a spraying device capable of uniformly applying paint is provided. This device utilizes a bidirectional threaded rod to rotate, causing two sets of sliding blocks to move closer or further apart, which in turn synchronously move the support rods closer or further apart. This allows for adjustment of the distance between the two sets of support rods, resolving the issue that the fixed structure of the spraying device cannot be adjusted according to the diameter of the pipe fittings.

[0006] To address the problems of the prior art, this application provides a spraying device capable of uniformly spraying paint, including a support, a fixed bracket disposed inside the support near one side edge, a movable bracket disposed inside the support and capable of moving along the X-axis, and an inner support mechanism disposed on the corresponding side of the fixed bracket and the movable bracket and capable of rotation. The inner support mechanism includes a rotating frame, and a rotating shaft is horizontally disposed at the center of one side of the rotating frame. The rotating shaft is rotatably installed inside the fixed bracket and the movable bracket.

[0007] On the other side of the rotating frame, there are two sets of slides that can move closer to or further away from each other. On one side of the slides, there is a horizontally fixed support rod that can contact the inner wall of the pipe.

[0008] One end of the rotating frame is fixed with a third servo motor, and the output end of the third servo motor is equipped with a rotatable bidirectional threaded rod. The slide is threadedly connected to the bidirectional threaded rod.

[0009] As one technical solution of this application, the rotating frame has sliding grooves for limiting the position on two corresponding sides;

[0010] The slide block has symmetrical sliders on both sides that can slide and engage with the slide groove.

[0011] As one technical solution of this application, a vertical plate is fixed at the bottom of the support near the side of the movable bracket;

[0012] The bottom of the fixed bracket is fixed with a first servo motor, and the output end of the first servo motor is connected to a rotatable lead screw. The end of the lead screw away from the first servo motor is rotatably mounted on the upright plate. The movable bracket has a threaded hole near the center of the bottom that can be threadedly connected to the lead screw.

[0013] As one technical solution of this application, two sliding rods for limiting are symmetrically fixed on the side of the bottom of the fixed bracket near the lead screw, and the end of the sliding rod away from the fixed bracket is fixed to the upright plate; the movable bracket is provided with a limiting hole on the side near the threaded hole, which can slide and cooperate with the sliding rod.

[0014] As one technical solution of this application, the top of the support is provided with a first slide that can move along the X-axis direction, and the top of the first slide is provided with a second slide that can move along the Y-axis direction.

[0015] An electric telescopic component is longitudinally fixed to the upper end face of one side of the second slide, and a spraying mechanism for uniformly spraying the surface of the pipe is installed at the output end of the electric telescopic component.

[0016] As one technical solution of this application, the spraying mechanism includes a fixed base fixed to the output end of the electric telescopic component, and a connecting part for conveying paint into the fixed base is provided on the top of one side of the fixed base.

[0017] On the other side of the mounting base is an atomizing nozzle for evenly spraying the paint inside the mounting base onto the surface of the pipe fitting.

[0018] As one technical solution of this application, a storage box for storing paint is fixed on the upper surface of the second slide.

[0019] As a technical solution of this application, a delivery pump is fixed on the upper surface of the second slide near the side of the storage box, and the output end of the delivery pump can extend into the interior of the storage box to extract the paint.

[0020] The two sides of the output end of the delivery pump are connected to flexible hoses that can communicate with the connection part.

[0021] The advantages of this utility model compared to the prior art are:

[0022] This application utilizes the rotation of a bidirectional threaded rod to move two sets of slides closer together or further apart, thereby synchronously moving the support rods closer together or further apart. This allows for adjustment of the distance between the two sets of support rods, solving the problem that the fixed structure of the spraying device cannot be adjusted according to the diameter of the pipe fittings.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figures 1-7 As shown, a spraying device capable of uniformly spraying paint includes a support 1, a fixed bracket 2 disposed inside the support 1 near one side edge, a movable bracket 7 disposed inside the support 1 and capable of moving along the X-axis, and an inner support mechanism 25 disposed on the corresponding side of the fixed bracket 2 and the movable bracket 7 and capable of rotation. The inner support mechanism 25 includes a rotating frame 251, and a rotating shaft 253 is horizontally disposed at the center of one side of the rotating frame 251. The rotating shaft 253 is rotatably installed inside the fixed bracket 2 and the movable bracket 7.

[0033] On the other side of the rotating frame 251, there are two sets of slides 26 that can move closer to each other or further away from each other. On one side of the slides 26, there is a horizontally fixed support rod 261 that can contact the inner wall of the pipe.

[0034] One end of the rotating frame 251 is fixed with a third servo motor 254. The output end of the third servo motor 254 is equipped with a rotatable bidirectional threaded rod 255. The slide block 26 is threadedly connected to the bidirectional threaded rod 255.

[0035] A second servo motor 24 is fixed to the side of the fixed bracket 2 away from the rotating frame 251. The output end of the second servo motor 24 is fixedly connected to the rotating shaft 253. When the second servo motor 24 is started, it drives the rotating shaft 253 to rotate, which in turn drives the rotating frame 251 to rotate. A third servo motor 254 drives the bidirectional threaded rod 255 to rotate. When the bidirectional threaded rod 255 rotates clockwise, it can drive the threaded slide blocks 26 on it to move closer together. When the two sets of slide blocks 26 move closer together, they will simultaneously drive the support rods 261 to move closer together. At this time, the distance between the two support rods 261 becomes smaller, so that the two support rods 261 can cooperate to fix the pipe with a smaller diameter. Conversely, when the bidirectional threaded rod 255 rotates counterclockwise, it can drive the two sets of threaded slide blocks 26 on it to move away from each other. At the same time, the slide blocks 26 will drive the two support rods 261 to move away from each other. At this point, the distance between the two support rods 261 increases, allowing them to work together to secure the larger diameter pipe. This effectively solves the problem that the spraying device cannot be adjusted according to the pipe diameter.

[0036] See Figure 6 As shown, the rotating frame 251 has corresponding sliding grooves 252 on its two sides for limiting movement.

[0037] The slide block 26 has symmetrical sliders 262 on both sides that can slide and engage with the slide groove 252.

[0038] To ensure the stability of the slide block 26, grooves 252 are provided on the corresponding sides of the rotating frame 251. When the slide block 26 moves, the slider 262 on the slide block 26 can slide along the grooves 252, effectively preventing the slide block 26 from shifting during movement.

[0039] See Figure 1 , Figure 2 and Figure 4 As shown, a vertical plate 11 is fixed to the side of the bottom of the support 1 near the movable bracket 7;

[0040] The bottom of the fixed bracket 2 is fixed with a first servo motor 21. The output end of the first servo motor 21 is connected to a rotatable lead screw 22. The end of the lead screw 22 away from the first servo motor 21 is rotatably mounted on the upright plate 11. The movable bracket 7 is provided with a threaded hole 71 near the bottom that can be threadedly connected to the lead screw 22.

[0041] A threaded hole 71 is horizontally opened near the bottom of the movable bracket 7 to engage with the lead screw 22. When the first servo motor 21 drives the lead screw 22 to rotate, the lead screw 22 can drive the movable bracket 7 to move horizontally through the threaded hole 71, so as to adjust the distance between the movable bracket 7 and the fixed bracket 2, thereby enabling the movable bracket 7 and the fixed bracket 2 to fix pipes of different lengths.

[0042] See Figure 1 , Figure 2 and Figure 4 As shown, two sliding rods 23 for limiting are symmetrically fixed on the side of the bottom of the fixed bracket 2 near the lead screw 22. The end of the sliding rod 23 away from the fixed bracket 2 is fixed on the upright plate 11. The movable bracket 7 has a limiting hole 72 on the side near the threaded hole 71 that can slide with the sliding rod 23.

[0043] To ensure the stability of the movable support 7, a limiting hole 72 is provided on the side of the movable support 7 near the threaded hole 71, which can slide with the slide rod 23. When the movable support 7 moves, it moves along the central axis of the slide rod 23 through the limiting hole 72, allowing the slide rod 23 to engage with the limiting hole 72 to restrict the movement of the movable support 7. This prevents the movable support 7 from shifting during movement and effectively ensures its stability.

[0044] See Figure 1 , Figure 2 and Figure 3 As shown, the top of the support 1 is provided with a first slide 3 that can move along the X-axis, and the top of the first slide 3 is provided with a second slide 4 that can move along the Y-axis.

[0045] An electric telescopic component 42 is longitudinally fixed on the upper end face of one side of the second slide table 4, and a spraying mechanism 5 for uniformly spraying the surface of the pipe is installed at the output end of the electric telescopic component 42.

[0046] A second electric slide rail 31 for driving the second slide 4 is fixed to the upper surface of the first slide 3. The bottom of the second slide 4 is slidably disposed with the second electric slide rail 31, allowing the second electric slide rail 31 to drive the second slide 4 to move along the Y-axis. At this time, the second slide 4 can drive the electric telescopic member 42 on one side to move synchronously, and then the electric telescopic member 42 drives the spraying mechanism 5 installed at the output end to move synchronously. Then the output end of the electric telescopic member 42 extends downward, causing the electric telescopic member 42 to drive the spraying mechanism 5 to move upward until the spraying mechanism 5 descends to one side of the pipe. A first electric slide rail 12 for driving the first slide 3 is fixed to the top of the support 1, and the bottom of the first slide 3 is slidably disposed with the first electric slide rail 12. When the spraying mechanism 5 sprays paint on the surface of the pipe, the first electric slide rail 12 can drive the first slide 3 to move at a uniform speed along the X-axis, so that the spraying mechanism 5 can evenly spray paint onto the surface of the pipe.

[0047] See Figure 3 As shown, the spraying mechanism 5 includes a fixed base 51 fixed to the output end of the electric telescopic member 42, and a connecting part 53 for conveying paint into the fixed base 51 is provided on the top of one side of the fixed base 51.

[0048] On the other side of the mounting base 51, there is an atomizing nozzle 52 for evenly spraying the paint inside the mounting base 51 onto the surface of the pipe.

[0049] When the electric telescopic component 42 moves the fixed base 51 downwards to one side of the pipe, the atomizing nozzle 52 on the fixed base 51 atomizes the paint, ensuring that the paint is evenly sprayed onto the surface of the pipe. This avoids the problem of uneven paint spraying.

[0050] See Figure 1 , Figure 2 and Figure 3 As shown, a storage box 6 for storing paint is fixed to the upper surface of the second slide 4.

[0051] By fixing the storage box 6 to the upper surface of the second slide 4, the paint can be stored inside the storage box 6.

[0052] See Figure 3 and Figure 7 As shown, a delivery pump 61 is fixed on the side of the upper end of the second slide 4 near the storage tank 6. The output end of the delivery pump 61 can extend into the interior of the storage tank 6 to extract the paint.

[0053] The two sides of the output end of the delivery pump 61 are connected to flexible hoses 62 that can communicate with the connection part 53.

[0054] When the spraying mechanism 5 is in operation, the delivery pump 61 starts, drawing paint from the storage tank 6 through its output end. The storage tank 6 then delivers the drawn paint to the hose 62 at the output end, and the hose 62, through the connector 53, delivers the paint into the fixed base 51. This ensures that the delivery pump 61, hose 62, and connector 53 stably supply paint to the spraying mechanism 5.

[0055] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
