Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hot melt marking machines, and in particular to a self-propelled marking paint scraping and rolling integrated machine. Background Technology
[0002] Hot melt road marking machine is the core equipment used for hot melt road marking on highways. It needs to be used in conjunction with a hot melt kettle to effectively improve construction efficiency and reduce labor intensity. Its functions include adjusting the thickness and width of the markings to support different scenario needs. Hot melt road marking machines can be divided into two types according to the driving method: dual-wheel electric drive type and hand-push type. Its core components include material bucket, bead box, control system and walking mechanism. Some models integrate stepless speed regulation system to adapt to complex construction environments.
[0003] When using a hot-melt road marking machine, the hot-melt paint is heated and melted, and then flows to one side. If the hot-melt paint is only smoothed by self-flow or by hand, the thickness is prone to appearing as "wavy" or "piled up". At the same time, 5% to 10% of the paint is left in the paint, which forms pinholes and hollows when cooled. After self-flowing, the paint does not fit well into the microscopic surface of the road. To address this, a self-propelled road marking paint scraping and rolling integrated machine is proposed. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a self-propelled road marking paint scraping and rolling integrated machine to solve the above-mentioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A self-propelled road marking paint leveling and rolling integrated machine includes a traveling base plate, a hot melt paint tank on the traveling base plate, a discharge pipe on one side of the hot melt paint tank, a collection box fixedly installed on one side of the traveling base plate, a side adjustment block fixedly installed on one side of the collection box, a flow component on the side adjustment block, an adjusting scraper movably installed on the side adjustment block, a fixing plate fixedly installed on one side of the traveling base plate, a mounting bracket mounted on the fixing plate via a lifting component, a pressure roller rotatably mounted on the mounting bracket, a height synchronization component between the pressure roller and the adjusting scraper, and a thickness measuring component mounted on the mounting bracket.
[0007] Preferably, the flow assembly includes an adjustment groove formed on the side adjustment block, a flow hole is formed on one inner wall of the adjustment groove, a bottom inclined groove is formed on the bottom inner wall of the adjustment groove, and the adjustment scraper is located in the adjustment groove.
[0008] Preferably, limit grooves are provided on both inner walls of the adjustment groove, limit blocks are fixedly installed on both sides of the adjustment scraper, the limit blocks are slidably installed in the limit groove, and the bottom of the adjustment scraper is provided with an arc-shaped bottom.
[0009] Preferably, the lifting assembly includes a telescopic cylinder fixedly mounted on a fixed plate, and the output end of the telescopic cylinder is fixedly connected to the top of the mounting bracket.
[0010] Preferably, the height synchronization component includes a set of synchronization drive blocks fixedly installed between the mounting bracket and the adjusting scraper.
[0011] Preferably, the thickness measuring component includes a displacement rod fixedly mounted on a mounting bracket, and the displacement rod is provided with displacement scale.
[0012] Preferably, a side baffle plate is fixedly installed on the side of the side adjusting block, and the pressure roller is located inside the side baffle plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the self-propelled road marking paint scraping and rolling integrated machine is equipped with an adjustable scraper. The heated paint will flow out from the flow hole and flow onto the ground along the inclined groove at the bottom. The adjustable scraper scrapes the flowing paint horizontally, and the paint is in a relatively flat state after scraping. The pressure roller can squeeze out the air inside the paint, making it less likely to have air bubbles. At the same time, the squeezing can make the paint contact the ground better and the adhesion strength is high.
[0014] The lifting component is set up so that the telescopic cylinder drives the pressure roller to move. The height synchronization component is set up so that the pressure roller and the adjusting scraper are adjusted synchronously and are at the same height position after adjustment. This can achieve the effect of scraping and rolling, and can adjust the thickness of the marking paint. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Refer to Figure 1-4 A self-propelled road marking paint leveling and rolling integrated machine includes a walking placement base plate 1, a hot melt paint tank 2 on the walking placement base plate 1, and a feeding pipe 3 on one side of the hot melt paint tank 2. After hot melt paint is added into the hot melt paint tank 2 and heated, it can form flowing paint, which then pushes the entire walking placement base plate 1. The bottom of the walking placement base plate is equipped with moving wheels to achieve self-propelled movement. In actual use, a motor can be added to the moving wheels to drive the movement, which can reduce the pushing intensity of personnel. A collection box 4 is fixedly installed on one side of the walking placement base plate 1, and a side adjustment block 5 is fixedly installed on one side of the collection box 4. A flow component is provided on the side adjustment block 5, and an adjusting scraper 9 is movably installed on the side adjustment block 5. A fixed plate 13 is fixedly installed on one side of the walking placement base plate 1, and a mounting bracket 15 is installed on the fixed plate 13 through a lifting component. A pressure roller 16 is rotatably installed on the mounting bracket 15, and a height synchronization component is provided between the pressure roller 16 and the adjusting scraper 9. A thickness measuring component is provided on the mounting bracket 15.
[0022] Furthermore, the flow assembly includes an adjustment groove 6 formed on the side adjustment block 5, a flow hole 7 formed on one inner wall of the adjustment groove 6, a bottom inclined groove 8 formed on the bottom inner wall of the adjustment groove 6, an adjustment scraper 9 located in the adjustment groove 6, limit grooves 11 formed on both inner walls of the adjustment groove 6, limit blocks 12 fixedly installed on both sides of the adjustment scraper 9, the limit blocks 12 slidingly installed in the limit grooves 11, and an arc-shaped bottom 10 formed at the bottom of the adjustment scraper 9. The heated hot melt coating enters the collection box 4 from the feed pipe 3 and finally flows out from the flow hole 7, flowing along the bottom inclined groove. The paint flows onto the ground through the groove 8. The adjustable scraper 9 is located on one side of the inclined groove 8 at the bottom, which can adjust the thickness of the flowing paint. The bottom of the adjustable scraper 9 is equipped with an arc-shaped bottom 10, which can scrape the flowing paint horizontally. After scraping, the paint is in a relatively flat state and will not be wavy. Behind the adjustable scraper 9, there is a pressure roller 16. The pressure roller 16 can squeeze the paint, and the air inside the paint will be squeezed out, making it less likely to have air bubbles. At the same time, the squeezing can make the paint contact the ground better and have high adhesion strength.
[0023] Furthermore, the lifting assembly includes a telescopic cylinder 14 fixedly mounted on the fixed plate 13. The output end of the telescopic cylinder 14 is fixedly connected to the top of the mounting bracket 15. The height synchronization assembly includes a set of synchronous drive blocks 17 fixedly mounted between the mounting bracket 15 and the adjusting scraper 9. When it is necessary to adjust the thickness of the coating, the telescopic cylinder 14 is activated to drive the mounting bracket 15 to move. The synchronous drive blocks 17 can synchronously drive the adjusting scraper 9 to move upward synchronously. The adjusting scraper 9 and the pressure roller 16 are at the same height position, which can achieve smoothing and rolling.
[0024] Furthermore, the thickness measuring component includes a displacement rod 18 fixedly mounted on the mounting bracket 15. The displacement rod 18 is provided with a displacement scale 19. By observing the indicated position of the fixed plate 13 on the displacement rod 18 while adjusting the height, the adjusted paint thickness can be known, making the adjustment more precise. A side blocking plate 20 is fixedly mounted on the side of the side adjusting block 5. The pressure roller 16 is located inside the side blocking plate 20. When the paint is scraped or rolled, the side is blocked, preventing collapse and ensuring that the marking paint is relatively neat.
[0025] In use: A hot melt paint box 2 is placed on the walking base plate 1. The heated hot melt paint enters the collection box 4 through the feed pipe 3 and finally flows out through the flow hole 7. The adjustable scraper 9 can adjust the thickness of the flowing paint. The bottom of the adjustable scraper 9 is equipped with an arc-shaped bottom 10, which can scrape the flowing paint horizontally. After scraping, the paint is in a relatively flat state and will not be wavy. The pressure roller 16 can squeeze the paint, and the air inside the paint will be squeezed out. At the same time, it can make better contact between the paint and the ground. When it is necessary to adjust the thickness of the paint, the telescopic cylinder 14 is activated to drive the mounting bracket 15 to move. The synchronous drive block 17 can synchronously drive the adjustable scraper 9 to move upward. The position of the adjustable scraper 9 and the pressure roller 16 is at the same height, which can achieve smoothing and rolling, which is convenient to use.
