Description

Technical Field

[0001] This invention relates to the field of steel pipe pretreatment technology, specifically to an automated steel pipe pretreatment painting equipment. Background Technology

[0002] Steel pipe pretreatment includes cleaning, rust removal, primer application, and inspection. Cleaning removes dirt, grease, and other impurities from the steel pipe surface to ensure cleanliness before coating. Rust removal uses mechanical or sandblasting methods to remove rust and scale, exposing the metal. After rust removal, the steel pipe surface should be dried and kept dry. Primer application involves applying a primer to the steel pipe surface to improve adhesion and corrosion resistance. The primer should be applied evenly without lumps or bubbles. After the primer dries, subsequent coating treatments should be performed. Finally, steel pipe surface defect detection instruments are used to inspect the surface to ensure it meets quality requirements.

[0003] Currently, in the pretreatment and painting process of steel pipes, some methods involve manual painting of the steel pipe surface, which is inefficient and increases the workload of workers. Other methods involve mechanical spraying of the steel pipe surface, but this makes it difficult to achieve uniform spraying, reducing the subsequent use effect of the painted steel pipe and causing resource waste.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3The automated steel pipe pretreatment painting equipment includes a support assembly 1. The support assembly 1 includes a working box 103 with an opening at the top and a paint storage assembly 4 located above the working box 103. A partition 105 is provided inside the working box 103. Several openings 104 are correspondingly provided on both sides of the working box 103 and on the partition 105. A feeding assembly 2 corresponding to the openings 104 is provided at one end of the working box 103. A painting assembly 3 is located inside the working box 103 between the partition 105 and the feeding assembly 2. The painting assembly 3 includes several toothed rings 301 rotatably disposed inside the working box 103. The toothed rings 301 correspond to the openings 104, and adjacent toothed rings 301 mesh with each other. A rotating ring 3 is movably provided inside the toothed rings 301. 02. The gear ring 301 has several fixed posts 303 distributed circumferentially. A rotating plate 304 is rotatably mounted on the fixed posts 303. A paint roller 307 is rotatably connected to one end of the rotating plate 304 away from the fixed posts 303. A sliding groove 305 is provided on the rotating plate 304. A sliding column 306 connected to the rotating ring 302 is slidably mounted in the sliding groove 305. An adjusting motor 308 is rotatably mounted on the rotating ring 302. A rotating threaded block 309 is rotatably mounted on the gear ring 301. One end of the adjusting motor 308 is connected to a screw 310 that is threadedly engaged with the rotating threaded block 309. A rotating rod 312 is rotatably mounted inside the working box 103. A rotating gear 311 that meshes with the gear ring 301 is provided on the rotating rod 312. The rotating rod 312 is connected to a rotating motor 313.

[0027] In this embodiment, the feeding assembly 2 enables automatic intermittent feeding of the steel pipe, and the paint storage assembly 4 enables painting of the steel pipe surface. Initially, the sliding column 306 is located at the end of the sliding groove 305 furthest from the fixed column 303, the distance between the painting rollers 307 is at its maximum, and the distance between the adjusting motor 308 and the rotating threaded block 309 is also at its maximum. When the steel pipe is positioned between the painting rollers 307, the adjusting motor 308 is energized and drives the screw 310 to rotate. The screw 310 engages with the rotating threaded block 309 via a threaded connection. The adjusting motor 308 is driven to approach the rotating threaded block 309. By approaching the rotating threaded block 309, the adjusting motor 308 causes the sliding column 306 to approach the fixed column 303. The sliding column 306, through its sliding engagement with the sliding groove 305, drives the rotating plate 304 to rotate inwards towards the gear ring 301. The rotating plate 304 drives the paint roller 307 to rotate synchronously. The paint roller 307 moves closer to each other and comes into contact with the outer wall of the steel pipe. Simultaneously, the gear ring 301 and the rotating ring 302 remain relatively stationary. The rotary motor 313 drives the rotating gear 311 to rotate via the rotating rod 312. The rotating gear 311 drives the gear ring 301 to rotate through gear meshing. The gear ring 301, in conjunction with the rotating ring 302, drives the paint roller 307 to roll around the surface of the steel pipe. The paint roller 307 performs a uniform painting operation on the surface of the steel pipe by rolling around it. It features intermittent automatic feeding, efficient and uniform painting, meeting the painting needs of steel pipes of different specifications and lengths, painting multiple steel pipes at once, stable and reliable structure, and simple and practical operation. The support assembly 1 also includes a base plate 101 located below the work box 103. The base plate 101 and the work box 103 are connected by a column 102. The bottom of the base plate 101 can also be equipped with casters to facilitate the movement of the device. The bottom of the work box 103 is provided with a cleaning port (not shown in the figure) located below the painting assembly 3. Through the cleaning port, it is convenient for the staff to clean the paint dripping into the processing box 103, thereby improving the cleanliness of the inside of the work box 103. At least three painting rollers 307 are provided between the symmetrically arranged toothed rings 301. The inner diameter of the rotating ring 302 is not less than the radius of the opening 104.

[0028] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 4The feeding assembly 2 includes a mounting frame 201 disposed on one side of the working box 103. Side grooves 202 are symmetrically arranged on both sides of the mounting frame 201. Supporting slide plates 203 are elastically and slidably disposed on the side grooves 202. A plurality of support rollers 204 are rotatably connected between the symmetrically arranged support slide plates 203. A wedge-shaped slide plate 206 is slidably disposed at the end of the mounting frame 201 away from the support slide plates 203. A cam 205 connected to a rotating rod 312 is movably abutted on the wedge-shaped slide plate 206. A guide rod 209 is symmetrically and inclinedly disposed on the side of the working box 103 near the mounting frame 201. The outer end of the guide rod 209 is inclined upward. A movable plate 208 is slidably disposed on the guide rod 209. A wedge-shaped slide plate 207 is disposed on the movable plate 208 and slides with the wedge-shaped slide plate 206. A spring 210 is connected between the movable plate 208 and the working box 103. An abutment plate 211 is elastically connected between the movable plate 208 and the support rollers 204.

[0029] In this embodiment, initially, the support roller 204 is at its highest point, the nearest end of the cam 205 abuts against the first wedge-shaped slide plate 206, the spring 210 is at its original length, and the abutment plate 211 is at its lowest point. When the steel pipe is placed between the support roller 204 and the abutment plate 211, the support roller 204 is subjected to force and drives the support slide plate 203 to slide downwards. The abutment plate 211 does not contact the steel pipe. The rotary motor 313 drives the cam 205 to rotate through the rotating rod 312. As the farthest end of the cam 205 approaches the first wedge-shaped slide plate 206, the first wedge-shaped slide plate 206 is subjected to force and moves downwards. The first wedge-shaped slide plate 206 pushes the movable plate 208 along the guide rod 209 towards the working box 103 by sliding with the second wedge-shaped slide plate 207. The spring 210 is subjected to force and contracts, and the distance between the movable plate 208 and the abutment plate 211 becomes smaller, so that the abutment plate 211 and the steel pipe... The pressure between the abutment plate 211 and the steel pipe gradually increases as the pipe surfaces come into contact, facilitating the abutment plate 211 to push the steel pipe towards the inside of the working box 103. As the farthest end of the cam 205 moves away from the wedge-shaped slide plate 206, the spring 210 extends and pushes the movable plate 208 away from the working box 103. The movable plate 208 drives the abutment plate 211 to move obliquely upward along the guide rod 209, reducing the pressure between the abutment plate 211 and the surface of the steel pipe, and causing the abutment plate 211 to move away from the surface of the steel pipe. The movable plate 208 pushes the wedge-shaped slide plate 206 back to its original position through the sliding cooperation between the wedge-shaped slide plate 207 and the wedge-shaped slide plate 206. This enables automatic intermittent feeding of the steel pipe, avoiding the low efficiency of manual feeding. At the same time, it enables flexible linkage between the painting component 3 and the feeding component 2, improving the practicality of the device. The mounting frame 201 is a U-shaped plate.

[0030] In one embodiment of the present invention, see Figure 1 and Figure 5The paint storage assembly 4 includes a paint storage tank 401 disposed above the work box 103. The bottom of the paint storage tank 401 is provided with a discharge port 402 corresponding to a plurality of painting assemblies 3. The bottom of the discharge port 402 is provided with a guide pipe 403, and a solenoid valve 404 is provided on the guide pipe 403.

[0031] In this embodiment, the paint storage tank 401 can temporarily store the paint, and the column 102 and the working box 103 can discharge the paint and drip it onto the surface of the steel pipe, so that the painting component 3 can evenly paint the surface of the steel pipe. The solenoid valve 404 can control the flow of the guide pipe 403, improving the practicality of the device. At the same time, when it is necessary to paint the steel pipe with two colors, two identical devices can be combined to achieve the painting operation of different colors of paint on the surface of the steel pipe, improving the applicability of the device.

[0032] In one embodiment of the present invention, see Figure 1 , Figure 2 , Figure 4 and Figure 6 The work box 103 is also equipped with a drying assembly 5. The drying assembly 5 includes a hot air blower 501 located on the top of the work box 103. The outer end of the hot air blower 501 is connected to an air guide pipe 502 that communicates with the inside of the work box 103. The air guide pipe 502 is located on the side of the partition 105 away from the painting assembly 3. The end of the air guide pipe 502 away from the hot air blower 501 is provided with an air outlet 503. The bottom of the work box 103 is provided with a plurality of exhaust ports 504, and the exhaust ports 504 correspond to the air outlets 503.

[0033] In this embodiment, the painted steel pipe is moved above the exhaust port 504, and the hot air blower 501 is powered on and blows hot air onto the surface of the steel pipe through the air guide pipe 502 and the air outlet 503. This can quickly dry the surface of the painted steel pipe, prevent the steel pipe from adhering to debris after painting, and facilitate the subsequent processing of the steel pipe.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
