Description

Technical Field

[0001] The invention relates to a road marking line forming system that automatically forms a road marking line through high-pressure gas. Background Art

[0002] In order to regulate the driving of vehicles on the road in a more orderly manner, it is necessary to construct and draw indicator lines on the surface of various roads. For the drawing of road indicator lines, it is often necessary to melt the relevant materials on site and quickly apply the materials to the surface of the road while maintaining high temperature. This marking process often requires the use of a marking machine.

[0003] Road marking machines are widely used in pavement construction to mark various restrictions, guidelines, and warnings on flat surfaces, including roads, highways, parking lots, plazas, and runways. With their speed, efficiency, and accuracy, road marking machines have played a significant role in urban planning and highway construction, significantly reducing both construction time and investment.

[0004] Most existing road marking machines use a spraying mechanism, applying paint to the road surface as the machine moves forward. However, the high impact of spraying paint can easily cause paint splashing, which not only wastes resources but also creates a messy road marking, affecting the aesthetics of the marking process. Furthermore, existing road marking machines are not suitable for use in cold weather, as the low temperatures outdoors can easily cause the paint to solidify, severely hindering the spraying process. Therefore, a road marking line forming system that uses high-pressure gas to automatically form the road marking line has emerged. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art and to provide a road marking line forming system that is automatically formed by high-pressure gas.

[0006] A road marking line forming system that automatically forms road marking lines using high-pressure gas includes a forming device installed inside a marking box. The forming device includes a housing. The upper surface of the marking box is provided with a feeding pipe that extends into the interior of the marking box and communicates with the housing. The surface of the marking box is provided with a discharge port corresponding to a discharge trough on the outer shell surface. A pressure roller group is provided below the discharge trough. The pressure roller group consists of a heated roller and a driven roller that are interconnected.

[0007] An inner roller is provided inside the shell, and an outer roller is wrapped around the outer wall of the inner roller. Several extrusion holes are provided on the surfaces of the inner roller and the outer roller. The inner roller is connected to a negative pressure adsorption device, and the outer roller is connected to the discharge trough through a discharge channel.

[0008] As a further improvement, a high-pressure chamber is fixed on the outer wall of the marking box, and the air outlet end of the high-pressure chamber extends to above the driven roller. If special road sections require reflective beads to be sprayed on the road marking lines, reflective beads can be directly added to the high-pressure chamber of the box. The high-pressure chamber will evenly spray the reflective beads on the road marking lines during operation.

[0009] As a further improvement, the shell consists of an outer protective shell and a cover plate screwed onto the side wall of the outer protective shell. During maintenance, the cover plate can be rotated in the opposite direction for removal.

[0010] As a further improvement, the heating roller is driven by an external motor, and the heating roller is driven by the motor. When the heating roller rotates, it drives the driven roller to rotate, and the driven roller plays a role in shaping and cooling. Due to the high viscosity of the road marking material, a sheet indicator line can be formed between the outer roller and the inner roller. The sheet indicator line flows from the discharge channel to the gap between the heating roller and the driven roller and rolls out. During the rolling out process, the heating roller heats the adhesive surface of the sheet indicator line, and the driven roller cools, cools down, and shapes the other side of the sheet indicator line, and cools the surface of the sheet indicator line through the high-pressure chamber, while spraying reflective beads.

[0011] As a further improvement, a gap is left between the driven roller and the heating roller, and the sheet indicator line rolls out from the gap, one side of it is heated, and the other side is shaped to prevent the road indicator line from sticking to debris and dust or causing uneven marking due to the surface not being completely dry after laying.

[0012] As a further improvement, the gap between the driven roller and the heating roller is equal to the thickness of the discharge channel, and the distance of the gap is equal to the thickness of the sheet indicator line, which can effectively ensure that the surface of the sheet indicator line is completely fitted with the pressure roller group, making the processing of the surface of the sheet indicator line more uniform and improving the laying effect.

[0013] As a further improvement, the marking box is installed on a marking trolley to facilitate marking work of the staff.

[0014] As a further improvement, the shell is cylindrical in shape.

[0015] Beneficial effects:

[0016] This device is different from traditional road marking machines. It avoids the use of paint spraying. Instead, the material shaping work is completed in the marking box. After the material is shaped, it forms a sheet indicator line. The sheet indicator line is then adhered to the ground through heating, which completely solves the shortcomings of splashing, waste and mess in the spraying process. At the same time, it is not affected by environmental factors, ensuring that the road indicator line is shaped when it is adhered to the ground, avoiding slow solidification of the material or the indicator line not being completely dry and sticking to debris and dust, resulting in uneven marking, thereby improving the beauty and neatness of the marking operation.

[0017] This device uses negative pressure adsorption to remove air from the material during the shaping process, ensuring the effect and aesthetics of the material after shaping, while improving the marking quality. Reflective beads can be added at any time during the marking process, without the need for manual spraying after marking or mixing them with the material before marking. This greatly reduces the process steps and labor workload of workers in the marking work, and helps to improve the efficiency of the marking operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown as a specific embodiment of the present invention, a road marking line forming system that is automatically formed by high-pressure gas includes a cover plate 1, a heating roller 2, a driven roller 3, a high-pressure chamber 4, a shell 11, an injection pipe 12, an outer roller 13, an inner roller 14, and a discharge channel 15.

[0024] A road marking line forming system that automatically forms road markings using high-pressure gas includes a forming device installed inside a marking box. The forming device includes a housing 11. A material injection pipe 12 is provided on the upper surface of the marking box. The injection pipe 12 extends into the interior of the marking box and communicates with the housing 11. A discharge port is provided on the surface of the marking box, corresponding to a discharge trough on the outer shell surface. A pressure roller group is provided below the discharge trough. The pressure roller group consists of a heated roller 2 and a driven roller 3 that are interconnected.

[0025] An inner roller 14 is provided inside the shell 11, and the outer wall of the inner roller 14 is wrapped with an outer roller 13. The surfaces of the inner roller 14 and the outer roller 13 are provided with a plurality of extrusion holes. The inner roller 14 is connected to a negative pressure adsorption device, and the outer roller 13 is connected to the discharge trough through the discharge channel 15.

[0026] A high-pressure chamber 4 is fixed on the outer wall of the marking box, and the air outlet end of the high-pressure chamber 4 extends to above the driven roller 3. If special road sections require reflective beads to be sprayed on the road marking lines, reflective beads can be directly added to the high-pressure chamber 4 of the box. The high-pressure chamber 4 will evenly spray the reflective beads on the road marking lines during operation.

[0027] The housing 11 is composed of an outer protective shell and a cover plate 1 screwed onto the side wall of the outer protective shell. During maintenance, the cover plate 1 can be rotated in the opposite direction for removal.

[0028] The heating roller 2 is driven by an external motor. When the heating roller 2 rotates, it drives the driven roller 3 to rotate. The driven roller 3 plays the role of shaping and cooling. Due to the high viscosity of the road marking material, a sheet indicator line can be formed between the outer roller 13 and the inner roller 14. The sheet indicator line flows from the discharge channel 15 to the gap between the heating roller 2 and the driven roller 3 and rolls out. During the rolling out process, the heating roller 2 heats the adhesive surface of the sheet indicator line, and the driven roller 3 cools, cools down and shapes the other side of the sheet indicator line, and cools the surface of the sheet indicator line through the high-pressure chamber 4, while spraying reflective beads.

[0029] There is a gap between the driven roller 3 and the heating roller 2, and the sheet indicator line rolls out from the gap, one side of it is heated and the other side is shaped to prevent the road indicator line from sticking to debris and dust or causing uneven marking due to the surface not being completely dry after laying.

[0030] The gap between the driven roller 3 and the heating roller 2 is equal to the thickness of the discharge channel 15, and the distance of the gap is equal to the thickness of the sheet indicator line, which can effectively ensure that the surface of the sheet indicator line is completely fitted with the pressure roller group, making the processing of the surface of the sheet indicator line more uniform and improving the laying effect.

[0031] The marking box is installed on the marking trolley to facilitate the marking work of the staff.

[0032] The housing 11 is cylindrical in shape.

[0033] During use, the marking material is continuously injected from the injection pipe. The material enters the shell due to the extrusion effect, and then enters the surface of the inner roller from the extrusion hole on the outer roller. Due to the effect of negative pressure adsorption, the excess air in the material is sucked out to form a sheet indicator line. The sheet indicator line flows out from the discharge channel to between the heating roller and the driven roller. The heating roller heats the adhesive surface of the sheet indicator line to ensure the adhesive effect, and the driven roller shapes the other side of the sheet indicator line.

[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, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0035] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of the present invention. In other words, equivalent changes and modifications made according to the scope of the present invention and the contents of the specification should still fall within the scope of the present invention.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
