[0029] Example

[0030] ReferenceFigures 1-4 As an embodiment of the present invention, a primer brushing device for the production of anti-corrosion pipes is provided, comprising: a main body unit 100 and a spraying unit 200.

[0031] The main unit 100 includes a base plate 101, a support plate 102 is provided on the base plate 101, and a paint bucket 107 is provided on one side of the base plate 101.

[0032] The spraying unit 200 includes a screw 201, a short rod 202 sleeved on the screw 201, a support plate 102 threadedly connected to the screw 201, and a hollow internal structure. A primer conveying component 203 is connected to the end of the screw 201 away from the short rod 202, and the primer conveying component 203 is connected to a paint bucket 107. A spray nozzle 204 is provided at the end of the screw 201 away from the primer conveying component 203, and the spraying direction of the spray nozzle 204 is away from the screw 201. A brush plate 205 is mounted on a short rod 202 at the axis. Multiple brush plates 205 are arranged in a circular array on the short rod 202. A drive motor 206 is fixedly mounted on the base plate 101, and the output end of the drive motor 206 is fixedly connected to the screw 201. The spraying unit 200 also includes an adjustment component 207 for adaptively adjusting the position of the brush plates 205, and a clamping component 208 for supporting the anti-corrosion pipe. Through the combination of the spraying unit 200 and the brush plates 205, efficient and uniform brushing of the inside of the pipe is achieved. The rotation of the screw 201 drives the short rod 202 and the brush plates 205 to rotate, while the nozzle 204 evenly sprays the anti-corrosion primer onto the inner wall of the pipe, ensuring uniform coverage of the anti-corrosion primer and improving the anti-corrosion effect.

[0033] According to one embodiment of the present invention, the adjustment component 207 includes a slip ring 2071, which is slidably sleeved on a short rod 202. A first rotating rod 2072 is rotatably connected to the slip ring 2071, and a second rotating rod 2073 is rotatably connected to the short rod 202. The first rotating rod 2072 and the second rotating rod 2073 are alternately arranged and rotatably connected at the middle position of the first rotating rod 2072 and the second rotating rod 2073. Limiting rods 2074 are provided at the ends of the first rotating rod 2072 and the second rotating rod 2073. A limiting frame 2075 is provided on the side of the brush plate 205 near the short rod 202. The limiting rod 2074 is located in the limiting frame 2075 and is slidably connected to the limiting frame 2075. A limiting ring 2076 is fixedly connected to the short rod 202. A first spring 2077 is sleeved on the outer surface of the short rod 202 between the limiting ring 2076 and the slip ring 2071.

[0034] According to one embodiment of the present invention, the clamping unit includes a movable rod 2081, a sliding groove 2082 is provided inside the support plate 102, the movable rod 2081 is located inside the sliding groove 2082, and multiple sliding grooves 2082 and movable rods 2081 are provided and distributed in a circumferential array. A second spring 2083 is provided inside the sliding groove 2082, and a clamping plate 2084 is provided on one side of the movable rod 2081.

[0035] According to one embodiment of the present invention, a connecting plate 209 is rotatably connected to the support plate 102, and an eccentric groove 210 is provided on the connecting plate 209. A guide rod 211 is fixedly connected to one side of the moving rod 2081, and the guide rod 211 extends into the interior of the eccentric groove 210.

[0036] According to one embodiment of this utility model, a guide groove 103 is provided on the base plate 101, and a base 104 is fixedly provided on the bottom of the support plate 102. The base 104 is located inside the guide groove 103, and the base 104 is slidably connected to the guide groove 103. The arrangement of the sliding groove 2082 and the base 104 can ensure that the support plate 102 on the base 104 can move horizontally stably. By manually rotating the connecting plate 209, the guide rod 211 moves closer to the screw 201, thereby driving the moving rod 2081 to slide in the guide groove 103 and compress the second spring 2083, thereby bringing the multiple clamping plates 2084 together and adhering one end of the pipe to be coated to the support plate 102. When the connecting plate 209 is released, the clamping plates 2084 spread outward under the restoring action of the second spring 2083, thereby clamping and fixing the pipe. At this time, the second spring 2083 is in a compressed state, providing sufficient clamping for the clamping plates 2084.

[0037] According to one embodiment of this utility model, a top rod 105 is provided on the base plate 101, and a support plate 106 is provided on the top rod 105. The top rod 105 and the support plate 106 provide auxiliary support for the pipeline, preventing the pipeline from tilting due to uneven weight distribution.

[0038] During use, place the pipe to be coated on the tray 106, then manually pull the slip ring 2071 to compress the first spring 2077, so that the brush plate 205 is close to the short rod 202 until it can be inserted into the pipe, and then put the pipe to be coated onto the screw 201. Release the slip ring 2071. Under the restoring action of the first spring 2077, the slip ring 2071 causes the first rotating rod 2072 to deflect, which in turn causes the second rotating rod 2073 to deflect simultaneously. This causes the brush plate 205 to move away from the short rod 202 until it is in contact with the inner wall of the pipe. Then, by manually rotating the connecting plate 209, the guide rod 211 moves closer to the screw 201, which in turn causes the moving rod 2081 to slide in the slide groove 2082 and compress the second spring 2083. This brings the multiple clamping plates 2084 together, bringing one end of the pipe to be coated against the support plate 102. Release the connecting plate 209. Under the restoring action of the second spring 2083, the clamping plates 2084 spread outward, thus clamping and fixing the pipe. At this time, the second spring 2083 is in a compressed state, providing sufficient clamping force for the clamping plates 2084.

[0039] Power is switched on, and drive motor 206 is started. The output end of drive motor 206 is fixedly connected to screw 201 via a coupling, driving screw 201 to rotate. The rotational motion of screw 201 is transmitted to support plate 102 through threaded connection, causing support plate 102 to move horizontally under the constraint of base 104 and guide groove 103. As screw 201 rotates, short rod 202 and brush plate 205 also rotate. Primer delivery component 203 draws anti-corrosion primer from paint bucket 107 and delivers it to spray head 204 through the hollow structure inside screw 201. Rotating spray head 204 evenly sprays anti-corrosion primer onto the rotating inner wall of pipe, forming a uniform anti-corrosion layer. While spraying with spray head 204, brush plate 205 also rotates and brushes onto the inner wall of pipe. Due to the presence of adjustment component 207, brush plate 205 can adaptively adjust its position according to the shape and size of the inner wall of pipe, ensuring that brush plate 205 is in close contact with the inner wall of pipe. This close contact allows for more even brushing and improves the anti-corrosion effect.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
