Description

Technical Field

[0001] This utility model relates to the field of spraying machine technology, and in particular to an automated acid-resistant coating spraying machine. Background Technology

[0002] A spray painting machine is a specialized coating equipment that uses spraying technology. It is widely used in the industrial and construction fields. Its function is to spray paint onto the surface that needs to be coated. With the development and widespread application of spraying technology, there are more and more types of spray painting machines. Depending on the application field and the sprayed material, spray painting machines can be divided into many types.

[0003] In the prior art, a spraying mechanism for a spraying machine, as described in patent publication number CN220072102U, includes a base. Two movable wheels are rotatably connected to both sides of one end of the base. A pusher frame is connected to one side of the upper end of the base, and a fixing point is provided at one end of the pusher frame. This invention addresses the problem that current spraying machines are generally operated manually with handheld spray guns, resulting in large spray volumes. However, current devices only have a single spraying mechanism design and do not have multiple spray pipes. Having only one spray pipe limits the coverage area and speed of spraying, especially in scenarios requiring large-area spraying, significantly reducing work efficiency. Furthermore, a single spray pipe may struggle to achieve uniform spraying, easily lowering spraying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automated acid-resistant coating spraying machine to solve the problem that the current devices only have a single design for the spraying mechanism and do not have multiple spraying pipes. Having only one spraying pipe means that the coverage area and speed of spraying will be limited, especially in scenarios that require large-area spraying, the work efficiency will be significantly reduced, and a single spraying pipe may not be able to achieve uniform spraying, which can easily reduce the spraying efficiency.

[0005] To achieve the above objectives, an automated acid-resistant coating spraying machine is provided, comprising a base frame with a shell-like opening on the top surface of the base frame. Inner plates are fixed around the inner perimeter of the base frame, and a placement box is fixed between the inner plates. A lid is provided on the top of the placement box, and two lifting rings are fixed on the top of the lid. An inlet pipe and an outlet pipe are fixed to the left and right ends of the outer side of the placement box, respectively, and both the inlet and outlet pipes extend into the interior of the placement box. Two spraying mechanisms are provided at the rear end of the outer side of the placement box. Each spraying mechanism includes a telescopic element, the lower end of which extends into the interior of the placement box. A support pipe is fixed to the top of the telescopic element, and a spray hood is fixed to the front end of the support pipe. The spray hood has a convex design, and multiple spray holes extend through its outer side.

[0006] According to the aforementioned automated acid-resistant coating spraying machine, a drive motor is fixed at the center of the right end of the outer side of the placement box, a rotating rod is rotatably connected to the inner side of the placement box, the output end of the drive motor passes through the inner side of the placement box and is fixedly connected to the outer side of the rotating rod through a coupling, and multiple stirring rods are fixedly arranged on the outer side of the rotating rod.

[0007] According to the aforementioned automated acid-resistant coating spraying machine, a placement groove extends through the outer front end of the placement box, a placement plate is fixed inside the placement groove, and multiple graduated grooves are provided at the center of the outer front end of the placement plate.

[0008] According to the aforementioned automated acid-resistant coating spraying machine, upper sleeve rods are provided at both ends of the inner side of the bottom frame, and lower sleeve rods are embedded in the inner side of the bottom end of the upper sleeve rods. The bottom end of the lower sleeve rods extends through to the bottom side of the bottom frame, and a support block is fixed at its bottom.

[0009] According to the automated acid-resistant coating spraying machine, the bottom frame is fixed with brackets on all four sides, and the brackets are rotatably connected with casters.

[0012] According to the automated acid-resistant coating spraying machine, the placement plate is entirely transparent.

[0013] The above solution offers the following advantages: A drive motor rotates the rotating rod and stirring rod, ensuring uniform mixing of the acid-resistant solution and preventing sedimentation from affecting the coating quality. The device is then moved to the spraying area via casters at the bottom. For fixation, the lower sleeve can be manually pulled out, and support blocks stabilize the device, preventing movement during spraying. Next, the valves on the two telescopic lower pipes are opened, allowing the acid-resistant solution to flow into the branch pipe under gravity or pressure, and then spray out through the spray nozzles of the spray hood. The convex design of the spray hood, combined with a multi-hole spray structure, expands the spray coverage area and improves uniformity. Adjusting the relative height of the telescopic upper and lower pipes changes the spray angle and range to suit different workpiece requirements. Finally, the transparent placement plate and surface scale groove facilitate real-time observation of the remaining solution level, allowing for timely replenishment.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-5This utility model discloses an automated acid-resistant coating spraying machine, comprising a base frame 1 with a shell-like opening on its top surface. Inner plates 2 are fixed around the inner perimeter of the base frame 1, and a placement box 3 is fixed between the inner plates 2. A lid 4 is provided on the top of the placement box 3, and two lifting rings 5 ​​are fixed to the top of the lid 4. An inlet pipe 6 and an outlet pipe 7 are fixed to the left and right ends of the outer side of the placement box 3, respectively, and both the inlet and outlet pipes 6 and 7 extend into the interior of the placement box 3. Two spraying mechanisms are provided at the rear end of the outer side of the placement box 3. Both spraying mechanisms include telescopic elements, with the lower end of the telescopic elements extending into the interior of the placement box 3. A support pipe 8 is fixed to the top of the telescopic element, and a spray hood 9 is fixed to the front end of the support pipe 8. The spray hood 9 has a convex design, and multiple spray holes extend through its outer side. In the prior art, this type of device currently only has a single design for the spraying mechanism and does not... Having multiple spray pipes is problematic because having only one spray pipe limits the coverage area and speed of spraying, especially in scenarios requiring large-area spraying, which significantly reduces work efficiency. Furthermore, a single spray pipe may struggle to achieve uniform spraying, further lowering efficiency. To address this, two spraying mechanisms can be installed at the rear of the outer side of the placement box 3. First, an acid-resistant solution is introduced into the placement box 3 through the inlet pipe 6. Then, the valves 23 at the top of the inlet pipe 6 and the outlet pipe 7 are closed. Next, the casters 20 are used to move the entire device to the designated position. Then, the valves 23 at the top of the two telescopic downpipes 21 are opened, allowing the acid-resistant solution introduced into the placement box 3 to flow through the two branch pipes 8 into the spray hood 9, where it is finally sprayed out. This dual spraying mechanism improves spraying efficiency and achieves automation.

[0025] A drive motor 10 is fixed at the center of the right side of the outer side of the placement box 3. A rotating rod 11 is rotatably connected to the inner side of the placement box 3. The output end of the drive motor 10 passes through the inner side of the placement box 3 and is fixedly connected to the outer side of the rotating rod 11 through a coupling. Multiple stirring rods 12 are fixed in an array on the outer side of the rotating rod 11. The drive motor 10 is used to rotate the rotating rod 11 and the stirring rods 12 to facilitate the stirring of the acid-resistant solution and achieve a uniform effect.

[0026] The outer front end of the placement box 3 has a placement groove 13, and a placement plate 14 is fixed inside the placement groove 13. Multiple scale grooves 15 are opened at the center of the outer front end of the placement plate 14. By opening scale grooves 15 at the outer front end of the placement plate 14, it is easy to observe the remaining amount of acid-resistant solution inside the placement box 3, so as to replenish it in time and also to make it easy to determine the spraying capacity.

[0027] Both ends of the inner side of the bottom frame 1 are provided with upper sleeve rods 16. The lower sleeve rod 17 is embedded in the inner side of the bottom end of the upper sleeve rod 16. The bottom end of the lower sleeve rod 17 extends through to the bottom side of the bottom frame 1, and a support block 18 is fixed at its bottom. By setting the upper sleeve rod 16, the lower sleeve rod 17 and the support block 18, the lower sleeve rod 17 can be inserted outward when the device stops, so that the two support blocks 18 can be used to support the device.

[0028] The base frame 1 is fixed with brackets 19 on all four sides. The brackets 19 are rotatably connected with casters 20 to facilitate the movement of the whole device. Both telescopic elements include a telescopic lower tube 21. A telescopic upper tube 22 is embedded in the inner side of the top of the telescopic lower tube 21. The telescopic upper tube 22 is fixed to the bottom side of the support tube 8. By setting the telescopic lower tube 21 and the telescopic upper tube 22, it is easy to change the overall height of the support tube 8 and the spray hood 9.

[0029] The inlet pipe 6, the outlet pipe 7, and the top of the telescopic lower pipe 21 are all equipped with valve bodies 23 to facilitate the flow of acid-resistant solution. The placement plate 14 is transparent to facilitate the observation of the remaining amount.

[0030] Working principle: First, the acid-resistant solution is injected into the placement box 3 through the inlet pipe 6. Then, the valves 23 on the inlet pipe 6 and the outlet pipe 7 are closed to ensure the solution is stored in a sealed manner. The drive motor 10 drives the rotating rod 11 and the stirring rod 12 to rotate, so that the acid-resistant solution is mixed evenly and to avoid sedimentation affecting the spraying quality. Next, the device is moved to the area to be sprayed by the universal wheels 20 at the bottom. When it needs to be fixed, the lower sleeve rod 17 can be manually pulled out, and the support block 18 is used to stabilize the device and prevent it from moving during the spraying process. Then, the valves on the two telescopic lower pipes 21 are opened. The acid-resistant solution flows into the branch pipe 8 under gravity or pressure, and then is sprayed out through the spray holes of the spray hood 9. The spray hood 9 adopts a convex design and is combined with a multi-hole spray structure to expand the spray coverage area and improve uniformity. By adjusting the relative height of the telescopic upper pipe 22 and the telescopic lower pipe 21, the spray angle and range can be changed to adapt to the needs of different workpieces. Finally, the transparent placement plate 14 and the surface scale groove 15 facilitate real-time observation of the remaining solution and timely replenishment. After spraying, the residual solution can be discharged through the liquid outlet pipe 7 for easy cleaning and maintenance.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
