Description

Technical Field

[0001] This utility model relates to the field of dyeing, and in particular to an automated dyeing device for steel pipes. Background Technology

[0002] Construction sites use a lot of steel pipes, such as for edge protection, entrance and exit passages, and scaffolding. To enhance warning and signage, different colors of paint are usually painted at equal intervals on the steel pipes, such as the common red and white alternating colors.

[0003] Traditional steel pipe dyeing methods involve workers manually applying dye with brushes. This method is not only inefficient but also makes it difficult to control the dyeing effect and finished product quality. Furthermore, the paint has a pungent odor, and long-term exposure can damage workers' health, posing significant drawbacks. Therefore, the applicant proposes an automated steel pipe dyeing device that can automatically complete the dyeing process, improving dyeing efficiency and ensuring product quality. Utility Model Content

[0004] To solve the technical problem of automatic dyeing of steel pipes, this utility model provides an automated dyeing device for steel pipes.

[0005] This utility model is achieved using the following technical solution: an automated steel pipe dyeing device, comprising a housing, on which are mounted:

[0006] A conveyor belt is installed inside the housing and is used to transfer steel pipes. A positioner is installed on the conveyor belt and is used to carry the steel pipes.

[0007] A dyeing roller is movably mounted on the upper surface of the conveying housing. The dyeing roller can move up and down, and a paint box is provided below the dyeing roller.

[0008] A drive wheel is disposed above the dyeing roller. The drive wheel is used to drive the steel pipe to rotate and can move up and down.

[0009] The above technical solution uses a conveyor belt and a positioner to transfer and transport steel pipes. The drive wheel drives the steel pipes and dyeing rollers to rotate through friction. When the dyeing rollers rotate, the paint in the paint box is transferred to the steel pipes, thus completing the dyeing process.

[0010] As a further improvement to the above solution, the positioner includes a base and an arc-shaped support plate. The base is fixedly installed on the conveyor belt, while one end of the arc-shaped support plate is movably engaged inside the base. An ejector spring is also provided between the arc-shaped support plate and the base.

[0011] With the above technical solution, the ejector spring will push the arc-shaped support plate upward to lift the steel pipe. At the same time, when the steel pipe is under pressure, it can also move downward by compressing the ejector spring.

[0012] As a further improvement to the above solution, the dyeing rollers are arranged in pairs, and a connecting frame is rotatably connected to the end of each dyeing roller. A telescopic rod is connected to the lower part of the connecting frame, and the lower end of the telescopic rod is fixedly connected to the paint box. The paint box is fixedly installed on the housing.

[0013] With the above technical solution, when the dyeing roller moves downward, the telescopic rod shortens, allowing the lower end face of the dyeing roller to contact the paint in the paint box.

[0014] As a further improvement to the above solution, a hydraulic lifting shaft is also provided at one end of the conveyor belt, and an installation plate is fixedly connected to the upper end of the hydraulic lifting shaft, on which a dyeing motor is fixedly installed.

[0015] As a further improvement to the above solution, two drive wheels are provided, and a drive shaft is provided between the two drive wheels, and the drive shaft and the drive wheels are fixedly connected.

[0016] As a further improvement to the above solution, a pulley is also installed on the drive shaft. The pulleys are arranged in pairs, and the two pulleys are connected by a belt drive. The other pulley is installed on the output shaft of the dyeing motor.

[0017] As a further improvement to the above solution, a bracket is also fixedly installed below the mounting plate. The bracket is sleeved on the outside of the drive shaft, and the bracket and the drive shaft are rotatably connected by a plane bearing. A limit wheel is also rotatably connected below the bracket.

[0018] As a further improvement to the above solution, a recycling rack is provided inside the housing and below the conveyor belt.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention uses a conveyor belt and a positioner to transfer steel pipes. By controlling the overall downward movement of the mounting plate, the drive wheel, steel pipe, and dyeing roller are brought into close contact. Then, the drive wheel is controlled to rotate, and the drive wheel drives the steel pipe and dyeing roller to rotate together through friction. When the dyeing roller rotates, it can automatically transfer the paint in the paint box to the steel pipe, automatically completing the dyeing process. The rotation of the steel pipe can make the paint spread evenly and improve the dyeing effect. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Please combine Figures 1-6 This embodiment of an automated steel pipe dyeing device includes a housing 1, on which two conveyor belts 2 are mounted for transferring steel pipes. To ensure the steel pipes remain stably on the conveyor belts 2, several positioners 3 are installed on the conveyor belts 2 in actual use. Each positioner 3 includes a base 31, an arc-shaped support plate 32, and an ejector spring 33. Specifically, the base 31 is fixedly mounted on the conveyor belt 2, and the upper surface of the arc-shaped support plate 32 is arc-shaped to facilitate support of the steel pipe, with its lower end engaging inside the base 31. An ejector spring 33 is also provided between the arc-shaped support plate 32 and the base 31. Under the action of the ejector spring 33, the upper end of the arc-shaped support plate 32 extends out of the base 31.

[0030] To dye the steel pipe, dyeing rollers 4 are provided. In this embodiment, a section of steel pipe needs to be intermittently dyed red. Therefore, three sets of dyeing rollers 4 are provided. Each set includes two rollers, and the two dyeing rollers 4 in each set are connected by a connecting frame 5. The dyeing rollers 4 and the connecting frame 5 are rotatably connected.

[0031] Additionally, a telescopic rod 6 and a paint box 7 are installed below the connecting frame 5. The telescopic rod 6 is a spring-loaded type, with an internal spring that automatically shortens when compressed. The upper end of the telescopic rod 6 is fixedly connected to the connecting frame 5, and the lower end is fixedly connected to the paint box 7. That is, the two dyeing rollers 4, the connecting frame 5, and the telescopic rod 6 are all installed inside the paint box 7.

[0032] As the conveyor belt 2 moves the steel pipe, it stops when it reaches the position of the dyeing roller 4. As explained above, the dyeing rollers 4 are arranged in pairs, side-by-side. Therefore, the steel pipe needs to stop between the two dyeing rollers 4. Since the height of the steel pipe is higher than the dyeing roller 4 at this point, a drive wheel 8 is provided to ensure sufficient contact between the steel pipe and the dyeing roller 4.

[0033] First, the drive wheel 8 can rotate, and through friction, it drives the steel pipe to rotate. Additionally, the drive wheel 8 can move up and down. When moving downwards, it can push the steel pipe downwards, ensuring full contact between the steel pipe and the dyeing roller 4.

[0034] Specifically, the drive wheels 8 are arranged in pairs, with a drive shaft 9 connecting each pair of drive wheels 8; that is, the drive wheels 8 and drive shaft 9 are fixedly connected. Additionally, a hydraulic lifting shaft 13 is installed at one end of the conveyor belt 2. A mounting plate 10 is fixedly connected to the upper end of the hydraulic lifting shaft 13, and a dyeing motor 11 is fixedly installed on the top of the mounting plate 10. To enable the dyeing motor 11 to drive the drive wheels 8, pulleys 12 are also provided. The pulleys 12 are arranged in pairs, connected by a belt drive. During installation, one pulley 12 is fixedly mounted on the drive shaft 9, and the other pulley 12 is mounted on the output shaft of the dyeing motor 11. Therefore, when the dyeing motor 11 is started, it will drive the drive shaft 9 and the drive wheels 8 to rotate together through the engagement of the pulleys 12.

[0035] In addition, a bracket 14 is fixedly installed on the lower end face of the mounting plate 10. The bracket 14 is sleeved on the outside of the drive shaft 9 and is rotatably connected to the drive shaft 9 through a plane bearing. The bracket 14 provides connection and support for the drive shaft 9.

[0036] In summary, when the steel pipe moves to the position of the dyeing roller 4, the conveyor belt 2 pauses. At this time, supported by the arc-shaped support plate 32, the height of the steel pipe is higher than that of the dyeing roller 4. Then, the hydraulic lifting shaft 13 drives the mounting plate 10 to move downward as a whole. The mounting plate 10 drives the drive shaft 9 and drive wheel 8 to move downward through the bracket 14. When the drive wheel 8 moves downward, it drives the steel pipe downward, so that the top of the steel pipe is in contact with the drive wheel 8, and the lower end face is in contact with the dyeing roller 4.

[0037] The dyeing motor 11 drives the drive wheel 8 to rotate, and the drive wheel 8 drives the steel pipe to rotate through friction. To prevent the steel pipe from shifting and losing contact with the drive wheel 8 and the dyeing roller 4 during rotation, a limit wheel 15 is rotatably connected below the bracket 14.

[0038] The limiting wheels 15 are arranged in pairs, located on the left and right sides of the steel pipe respectively. In this embodiment, there are two sets of limiting wheels 15, that is, four limiting wheels 15. When the drive wheel 8 presses down on the steel pipe from the top, the limiting wheels 15 on both sides can prevent the steel pipe from jumping and disengaging from the drive wheel 8 and the dyeing roller 4.

[0039] After dyeing is complete, the dyed steel pipe needs to be removed. For temporary storage of the steel pipe, a recycling rack 16 is installed inside the housing 1, below the conveyor belt 2. After dyeing, the hydraulic lifting shaft 13 resets, causing the mounting plate 10 to move upwards. When the drive wheel 8 disengages from the steel pipe, the arc-shaped support plate 32 moves upwards under the action of the ejector spring 33, lifting the steel pipe and separating it from the dyeing roller 4. If the conveyor belt 2 continues to operate at this time, the steel pipe falls down into the recycling rack 16 below.

[0040] The implementation process and principle of an automated steel pipe dyeing device in this application embodiment are as follows:

[0041] (I): Place the steel pipe on the positioner 3, and the conveyor belt 2 will start running. This will move the steel pipe, and when the steel pipe reaches the middle of the dyeing roller 4, the conveyor belt 2 will stop (see reference). Figure 3 At this time, drive wheel 8 is directly above the steel pipe.

[0042] (II): The hydraulic lifting shaft 13 drives the mounting plate 10 to move downwards as a whole, and the drive wheel 8 moves downwards, contacting the top of the steel pipe. The drive wheel 8 continues to move downwards, pushing the steel pipe downwards, at which point the steel pipe contacts the dyeing roller 4 below. At the same time, the arc-shaped support plate 32 compresses the ejector spring 33 and retracts into the base 31. At this time, the limit wheels 15 are located on both sides of the steel pipe.

[0043] (III): Through the cooperation of the dyeing motor 11 and the pulley 12, the drive wheel 8 is driven to rotate. The drive wheel 8 drives the steel pipe to rotate through friction. Since the dyeing roller 4 is covered with paint, the paint is transferred to the steel pipe when it rotates. The dyeing of the steel pipe is completed.

[0044] Additionally, as the steel pipe moves downwards, it also presses down on the dyeing roller 4. The telescopic rod 6 below the dyeing roller 4 and connecting frame 5 also shortens, causing the dyeing roller 4 to move downwards. The bottom of the dyeing roller 4 then contacts the paint in the paint box 7. When the steel pipe rotates subsequently, friction drives the dyeing roller 4 to rotate as well. During this rotation, the dyeing roller 4 automatically transfers the paint from the paint box 7 to itself. Therefore, the paint can be transferred to the steel pipe. In other words, when the drive wheel 8 rotates, friction drives the steel pipe and dyeing roller 4 to rotate, and the dyeing roller 4 automatically transfers the paint from the paint box 7 to the steel pipe through rotation. This quickly completes the automatic dyeing of the steel pipe. The rotation of the steel pipe ensures even paint application, thus improving dyeing efficiency and effect.

[0045] (iv): After dyeing is completed, the drive wheel 8 stops rotating, and at the same time, the hydraulic lifting shaft 13 drives the mounting plate 10 to move upward as a whole. The drive wheel 8 and the steel pipe are no longer in contact. Under the restoring force of the ejector spring 33, the arc-shaped support plate 32 pushes the steel pipe upward, and the steel pipe and the dyeing roller 4 are no longer in contact. At this time, the dyed steel pipe can be taken out, or the conveyor belt 2 can be controlled to continue running so that the steel pipe automatically falls into the recycling rack 16.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
