Among them, first adjusting assembly 100 is used for adjusting the relative position of second adjusting assembly 200 and road marking machine main body 000, and second adjusting assembly 200 is used for adjusting the direction of coating extrusion cutter head 001.

[0036] Specifically, first adjusting assembly 100 is fixedly connected with road marking machine main body 000, provides stable support, and is connected with second adjusting assembly 200 through the adjusting end, allows second adjusting assembly 200 to carry out position adjustment in a specific range. First adjusting assembly 100 can realize the adjustment of height direction or transverse direction through sliding or rotating, changes the relative position of coating extrusion cutter head 001 and road marking machine main body 000.

[0037] Further, through the combined design of first adjusting assembly 100 and second adjusting assembly 200, the embodiment realizes the double adjustment function of coating extrusion cutter head 001 position and direction, significantly improves the adaptability and operation convenience of the equipment. In addition, the design simplifies the installation process of coating extrusion cutter head 001, improves the working efficiency and marking quality of road marking machine.

[0038] It is worth mentioning that the connection mode of first adjusting assembly 100 and road marking machine main body 000 can be screw connection, slide rail connection or other quick disassembly and assembly forms, to adapt to different equipment installation demands. Second adjusting assembly 200 can adopt multi-degree-of-freedom activity design, for example, hinged or spherical hinge structure, to enhance the flexibility of coating extrusion cutter head 001 direction adjustment. The shape of coating extrusion cutter head 001 can be selected as trapezoidal, fan-shaped or other geometric shapes according to operation demand.

[0039] Please refer to Figures 1-3In a possible implementation, the first adjusting assembly 100 includes an adjusting support 110 and a fixing support 120. The adjusting support 110 is arranged at one end of the driving member 210 away from the head assembly, and one end of the adjusting support 110 is connected with the road marking machine body 000 for adjusting the opening size of the paint outlet; one end of the fixing support 120 is fixedly connected with the road marking machine body 000, and opposite sides of the fixing support 120 are sleeved with the adjusting support 110 for fixedly mounting the adjusting support 110.

[0040] Specifically, the fixing support 120 is connected with the road marking machine body 000 by bolts, welding or other fixing manners, and provides stable mounting and guiding functions. The adjusting support 110 is sleeved on the two sides of the fixing support 120 and can slide or stretch along the axial direction of the fixing support 120, so as to realize the adjustment of the opening size of the paint outlet. The movable end of the adjusting support 110 is connected with the driving member 210, and the head assembly can be further driven to realize the control of the opening and closing state.

[0041] Further, the present embodiment provides a stable support structure and efficient adjusting function through the combination of the fixing support 120 and the adjusting support 110. The accurate control of the paint flow is realized through the movement of the adjusting support 110, and the operation performance and operation adaptability of the equipment are enhanced. In addition, the design structure is simple and convenient for maintenance and replacement.

[0042] It is worth noting that the geometric shape of the fixing support 120 can be designed as a rectangle, a cylinder or other adaptive structure forms to meet the installation requirements of different equipment spaces. The material of the adjusting support 110 can be selected as an aluminum alloy, a stainless steel or a high-strength engineering plastic to balance the lightweight and durability requirements of the equipment. The adjusting mode can be adjusted as a threaded rotation type or an electric sliding rail type according to the application scene to improve the operation efficiency and adjusting accuracy.

[0043] Please refer to Figures 1-3 In a possible implementation, the installation structure of the extrusion head 001 of the road marking machine, the adjusting support 110 is connected with the road marking machine body 000 through threads, and the other end of the adjusting support 110 is movably connected with the second adjusting assembly 200.

[0044] Specifically, one end of the adjusting support 110 is fixedly connected with the road marking machine body 000 through threads, and the other end is connected with the second adjusting assembly 200 through a movable connection manner. The threaded connection part of the adjusting support 110 can adjust the accurate position in the height direction by rotating, for example, by changing the number of thread rotation, so that the adjusting support 110 moves in the height direction, thereby realizing the accurate control of the height of the extrusion head 001. The movable connection part can be a hinged or spherical hinge structure, which ensures that the second adjusting assembly 200 flexibly adjusts the direction of the extrusion head 001 within a certain range.

[0045] In actual use, the design of the adjusting support 110 facilitates the operator to quickly adjust the position and direction of the coating and extruding tool head 001 to adapt to different marking line widths and thicknesses, while ensuring the stability of the coating and extruding tool head 001. The flexibility of the movable connection further enhances the adaptability of the device in complex working environments.

[0046] Further, the present embodiment realizes the dual functions of height adjustment and flexible direction adjustment of the adjusting support 110 through the combination of threaded connection and movable connection. The high-precision characteristics of threaded connection make the adjustment process of the adjusting support 110 more stable, avoiding the inconvenience and inaccuracy problems caused by traditional fixed structures.

[0047] It is worth noting that the threaded connection part of the adjusting support 110 can be replaced by a sliding rail type guide mechanism or a quick locking device to improve the adjustment efficiency and assembly convenience. The movable connection part can adopt an elastic coupling or a ball structure to further improve the direction adjustment range and adjustment accuracy. In addition, the material of the adjusting support 110 can be selected from stainless steel, carbon steel or high-strength composite materials to meet the strength and corrosion resistance requirements of different use scenarios.

[0048] In one possible embodiment, a mounting structure of a coating and extruding tool head 001 of a road marking machine, the adjusting support 110 is internally provided with a tensioning member 111, one end of the tensioning member 111 is fixedly connected with the road marking machine body 000, the other end of the tensioning member 111 abuts against the adjusting support 110, and the tensioning member 111 is used to provide pre-stress for the adjusting support 110.

[0049] Specifically, the adjusting support 110 is internally designed with a tensioning member 111 for providing continuous pre-stress during adjustment. One end of the tensioning member 111 is connected with the road marking machine body 000 by welding or bolt fixation, and the other end abuts against the supporting surface of the adjusting support 110. When the position of the adjusting support 110 changes, the tensioning member 111 absorbs external force through its elastic deformation and provides restoring force, so that the adjusting support 110 always remains stable during adjustment.

[0050] The tensioning member 111 can adopt a resilient spring, a gas spring or a spiral spring design, and its elastic parameters (such as stiffness or elastic coefficient) can be flexibly configured according to the use scenario of the adjusting support 110. The presence of pre-stress not only improves the anti-vibration performance of the adjusting support 110, but also effectively prevents errors caused by vibration of the coating and extruding tool head 001 during operation.

[0051] Further, the present embodiment provides reliable prestress support for the smooth adjustment of the adjusting support 110 by arranging the tensioning member 111, significantly improving the stability and accuracy of the coating and extrusion tool bit 001 adjustment. The elastic recovery characteristics of the tensioning member 111 can maintain the reliability of the system for a long time, while reducing the maintenance frequency of the equipment.

[0052] It is worth noting that the tensioning member 111 can be replaced by other forms of elastic elements, such as rubber elastic bodies or wave springs, to adapt to more complex working environments. The installation method of the tensioning member 111 can be designed as an embedded structure, or can be simplified by an external form to facilitate replacement and maintenance. The material of the tensioning member 111 can be selected from high-temperature-resistant and corrosion-resistant materials, such as stainless steel or special alloys, to extend its service life.

[0053] Please refer to Figure 3 In one possible implementation, the mounting structure of the coating and extrusion tool bit 001 of the road marking machine, the tensioning member 111 is a rebound spring, one end of the rebound spring is fixedly connected with the road marking machine body 000, and the other end is abutted with the adjusting support 110.

[0054] Specifically, the rebound spring as a form of the tensioning member 111 has one end fixed on the road marking machine body 000 by welding or bolt method, and the other end abuts with the bottom support surface of the adjusting support 110. The elastic recovery force generated by the rebound spring during the movement of the adjusting support 110 can provide continuous upward support force for the adjusting support 110, thereby improving the stability and reliability of the adjustment process.

[0055] In actual application, the specifications of the rebound spring can be selected according to the stress condition of the adjusting support 110 to have different elastic coefficients and turns. For example, in the scene of large line thickness, a spring with stronger stiffness can be selected to enhance the support effect, while in the scene of thin line, a softer spring can be selected to ensure the adjustment sensitivity.

[0056] Further, by using the rebound spring, the present embodiment introduces a simple and efficient elastic support scheme in the structure of the adjusting support 110, significantly enhancing the reliability and durability of the adjustment system. The rebound spring can maintain good elastic performance for a long time, and its structure is simple, easy to replace and maintain.

[0057] It is worth noting that the rebound spring can be replaced by other forms of elastic elements, such as coil springs, gas springs or multi-layer composite elastic sheets, according to actual needs. The position design can be embedded or external according to the space layout for easy operation. The material of the rebound spring can be selected from carbon steel, stainless steel or galvanized alloy to improve its corrosion resistance and fatigue resistance.

[0058] Please refer to Figure 3In a possible implementation, the mounting structure of the squeegee head 001 of the road marking machine comprises a fixed support 120 and an adjusting support 110. The opposite sides of the fixed support 120 are sleeved with the adjusting support 110, so that the adjusting support 110 can extend and retract along the axial direction of the fixed support 120.

[0059] Specifically, the two sides of the fixed support 120 are designed with guide grooves or rails, which are sleeved with the guide structure of the adjusting support 110 to form a stable sliding guide fit. The adjusting support 110 can slide along the axial direction in the guide rail of the fixed support 120 through manual operation or a driving device, so as to realize accurate adjustment of the position of the squeegee head 001.

[0060] In order to ensure the stability of the sliding process, the surface of the guide rail can be provided with a lubricating layer or a ball bearing to reduce friction and improve the adjustment efficiency. The fixed support 120 is fixedly connected with the main body 000 of the road marking machine through bolts or welding, so as to ensure the stability of the entire adjusting mechanism.

[0061] Further, the sleeve design of the fixed support 120 and the adjusting support 110 realizes the stability and accuracy of the position adjustment of the adjusting support 110. The sleeve structure not only improves the anti-vibration performance of the adjusting system, but also enables the squeegee head 001 to more flexibly adapt to the operation requirements of different marking lines.

[0062] It is worth noting that the guide rail design of the fixed support 120 can adopt a linear type, a curved type or other special geometric forms to meet different marking requirements. The sliding mode of the adjusting support 110 can be realized through a ball rail or a roller block to achieve higher accuracy. The material of the fixed support 120 can be selected from high-strength alloy or lightweight engineering plastic to balance light weight and durability.

[0063] Please refer to Figure 3 In a possible implementation, the mounting structure of the squeegee head 001 of the road marking machine comprises a second adjusting assembly 200. The second adjusting assembly 200 comprises a driving member 210. The fixed end of the driving member 210 is fixedly connected with the main body 000 of the road marking machine, and the driving end of the driving member 210 is fixedly connected with the squeegee head 001. The driving member 210 is used to drive the squeegee head 001 to rotate along the axial direction, so as to control the opening and closing of the squeegee edge.

[0064] Specifically, the driving member 210 in the second adjusting assembly 200 is connected with the road marking machine body 000 through its fixed end, providing a stable support basis. The driving end of the driving member 210 is connected with the coating and extruding knife head 001 through a hinge or other movable connection, which can directly drive the coating and extruding knife head 001 to realize rotation in the axial direction. The driving member 210 can be selected from a gas cylinder, an electric push rod, or a hydraulic cylinder, and the appropriate driving mode is selected according to the specific working scene. The control of the driving member 210 can be completed by hand, foot switch, or intelligent control system. The rotation or linear motion of the driving end can quickly open or close the coating outlet of the coating and extruding knife head 001, thereby realizing the opening and closing control of the coating and extruding knife head. By adjusting the output parameters of the driving member 210, the coating spraying amount, spraying angle, and the thickness and width of the marking line can be accurately controlled.

[0065] Further, the present embodiment significantly improves the flexibility and accuracy of the coating and extruding knife head 001 control by setting the driving member 210. The efficient driving function of the driving member 210 not only ensures the quick response of the coating and extruding knife head opening and closing, but also effectively avoids the problem of uneven spraying caused by manual operation, thereby improving the quality and consistency of the marking operation. In addition, the modular design of the driving member 210 facilitates maintenance and replacement, reducing equipment maintenance costs.

[0066] It is worth noting that the connection form of the driving member 210 can be selected from quick buckles, elastic couplings, or ball hinges according to actual needs to enhance the flexibility and reliability of the connection. The type of the driving member 210 can be extended to a servo motor or a stepper motor to adapt to higher precision control requirements. The connection position between the coating and extruding knife head 001 and the driving member 210 can be set to be adjustable to facilitate the adaptation of different spraying angles and widths.

[0067] Please refer to Figures 1-3 In one possible implementation, a mounting structure of a coating and extruding knife head 001 of a road marking machine, the first adjusting assembly 100, the second adjusting assembly 200, and the coating and extruding knife head 001 are all provided with several and are one-to-one mounted.

[0068] Specifically, a plurality of first adjusting assemblies 100 are respectively installed at different positions of the road marking machine main body 000, and the adjusting end of each first adjusting assembly 100 is connected with a second adjusting assembly 200. The adjusting end of each second adjusting assembly 200 is fixedly connected with a coating and extruding tool bit 001. The adjusting assembly and the coating and extruding tool bit 001 are in one-to-one correspondence, forming a multi-module structure, which can flexibly adjust the position and direction of each coating and extruding tool bit 001 according to the operation demand. This arrangement is particularly suitable for the operation demand of multi-line marking or wide-line marking. For example, when multiple parallel lines need to be drawn at the same time, each coating and extruding tool bit 001 can independently adjust the spraying width and direction to ensure the uniformity of the line width and thickness. Through the cooperative work of multiple modules, the device can quickly adapt to diversified road marking operation scenes.

[0069] Further, the embodiment realizes the dynamic adjustment capability of the line width and quantity through the modular design. The one-to-one correspondence design of the plurality of coating and extruding tool bits 001 facilitates the operator to independently control the spraying parameters of each coating and extruding tool bit 001, further improving the operation efficiency and flexibility of the road marking machine. At the same time, the modular installation structure facilitates the maintenance and replacement of the coating and extruding tool bit 001 and its adjusting assembly, significantly reducing the failure influence range of the device.

[0070] It is worth noting that the number of the first adjusting assembly 100 and the second adjusting assembly 200 can be flexibly increased or decreased according to the actual operation demand, for example, increasing the number of components when drawing wide-line marking, and reducing the number of components when narrow-line marking. The material, shape and size of each coating and extruding tool bit 001 can be independently configured to adapt to different marking requirements. In order to further improve the control precision, a separate control system can be provided for each coating and extruding tool bit 001 to realize remote or automatic adjustment function.
