Description

Technical Field

[0001] The utility model relates to the technical field of hot-melt marking line scribing, in particular to an automatic scribing device for hot-melt marking lines. Background Technique

[0002] The automatic scribing device for hot-melt marking lines is an advanced tool designed specifically for road marking construction. This device precisely heats the hot-melt paint to an appropriate temperature and uses a precise mechanical device to evenly and smoothly lay the paint on the road surface, thereby creating clear and durable road markings. Its core components include an efficient heating system, a stable paint storage tank, a precise pumping system, an intelligent control system, and a fine scribing nozzle, etc.

[0003] Using an automatic scribing device can not only significantly improve the efficiency of road marking construction but also ensure the quality of the markings, such as uniformity and adhesion, thus greatly reducing the errors and high costs that may be brought by manual operations. Due to its excellent durability and outstanding night-time reflective effect, hot-melt markings have been widely used in various scenarios such as urban roads, highways, and parking lots.

[0004] However, in the actual use process, whether it is manual or mechanical observation methods, there are certain limitations. Manual observation highly depends on the experience and concentration of the operator and is extremely vulnerable to factors such as fatigue, line-of-sight limitations, and subjective judgments, resulting in deviations in the markings. Although mechanical observation can reduce human errors to a certain extent, its flexibility is insufficient. When facing complex or irregular road conditions, it may not be able to make accurate judgments and adjust the scribing direction. In addition, the existing observation deviation structures often lack the ability of real-time adjustment. Once a deviation is found, manual intervention is often required, which will undoubtedly reduce the operation efficiency and increase costs. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an automatic scribing device for hot-melt marking lines, which can effectively solve the problems put forward in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An automatic scribing device for hot-melt marking lines includes a support base, a material bucket, moving wheels, a feeding pump, and connecting pipes. The material bucket is installed on one side of the upper end of the support base through a support frame. The feeding pump is installed on the other side of the upper end of the support base.

[0008] A U-shaped frame is provided on the side wall of the support base, and a scribing head is installed on the frame of the U-shaped frame. The scribing head is connected to the feeding pump through a conveying hose, and road surface scribing is realized through the scribing head;

[0009] An installation frame is installed inside the U-shaped frame, and a laser is installed at the bottom of the inner frame of the installation frame. A transparent plate is installed inside the installation frame, and scales are provided on the transparent plate. The position of the scribing head is adjusted through the laser and the scales to make the scribing accurate.

[0010] As a further preferred embodiment of the present invention, the support frame is installed on the support base through bolts, and the moving wheels are fixed on the support frame through bolts. The material bucket is fixed to the support frame through a clamp, bolts and an anti-slip ring;

[0011] As a further preferred embodiment of the present invention, the feeding pump is installed on the support base through bolts, and the U-shaped frame is fixed on the support base through bolts, nuts and anti-slip gaskets. The connecting pipe is communicated with the discharge port on the side wall of the material bucket, and the conveying hose is communicated with the feeding port of the scribing head;

[0012] As a further preferred embodiment of the present invention, side blocks are provided at the lower end of the installation frame, and the installation frame is fixed on the U-shaped frame through bolts.

[0014] As a further preferred embodiment of the present invention, the transparent plate is placed on the inner retaining strips of the installation frame, and the transparent plate is adhesively connected to the installation frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, during the process of improving the scribing operation accuracy, we adopt advanced laser technology. Through the real-time comparison of the precise light projected by it with the fine scales on the transparent plate, the operator can quickly and accurately adjust the position of the scribing head based on these clearly visible reference points. This innovative design greatly enhances the accuracy and consistency of the scribing operation, ensuring that each marking line can achieve the best effect.

[0017] In order to cope with various complex road surface conditions, we specially design an installable inclined frame. This design allows the operator to flexibly adjust the inclination angle of the scribing device according to actual needs, so as to ensure the best scribing effect under various road conditions. At the same time, the application of the transparent plate not only ensures the clear readability of the scales, but also effectively avoids the scale displacement caused by factors such as vibration through its stability, further enhancing the stability of the scribing.

[0018] In addition, we have introduced the design of a U-shaped frame to reinforce the scribing head and optimize the operator's observation and adjustment experience. This design not only stabilizes the position of the scribing head but also enables the operator to more intuitively observe the state of the scribing head and make fine adjustments when necessary. In this way, we have further improved the precision of scribing, ensuring that the clarity, adhesion, and width consistency of the marking lines all meet high standards.

[0019] Regarding the movement and positioning of the equipment, we have adopted an efficient mobile wheel system. This system endows the equipment with excellent flexibility and rapid response capabilities, enabling the operator to easily move the equipment to the designated position and accurately position it. This not only improves the operation efficiency but also reduces unnecessary waiting time, providing strong support for the safety and smoothness of road traffic.

[0020] We focus on the overall layout and delicate design of the equipment. Through reasonable layout and optimized structural design, we ensure the smooth transmission of the hot melt material and the uniformity of spraying. This design makes the scribing operation more efficient and stable, laying a solid foundation for building a safe and smooth road traffic environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Such as Figure 1 - Figure 4As shown in the figure, an automatic line marking device for hot melt road markings is carefully designed and incorporates multiple key components to achieve efficient and precise line marking functions. The main body of the device is firmly supported by a support base 1. On one side of its upper end, a material bucket 3 is firmly installed through a support frame 2 (fastened by bolts). This material bucket 3 is used to store hot melt road marking materials. On the other side of the support base 1, a feeding pump 5 is installed (also fixed by bolts). This pump extracts the materials in the material bucket 3 through a connecting pipe 6 (tightly connected to the discharge port on the side wall of the material bucket 3). In addition, at the four corners of the lower end of the support base 1, moving wheels 4 are installed, facilitating the flexible movement and positioning of the device. These moving wheels 4 are also installed on the support base 1 structure by bolts.

[0028] To achieve precise line marking operations, a U-shaped frame 8 is specifically provided on the side wall of the support base 1. This frame is not only structurally stable (fixed to the support base 1 by bolts, nuts, and anti-slip gaskets), but also undertakes the important task of installing the line marking head 9. The line marking head 9 is connected to the feeding pump 5 through a conveying hose 7, ensuring that the hot melt material can be smoothly transported to the line marking head 9, and then leaving clear road markings on the road surface.

[0029] To improve the accuracy of line marking, an installation frame 10 is also cleverly integrated inside the U-shaped frame 8. At the bottom of this frame, a laser 11 is installed (fixed by bolts and equipped with rubber rings to ensure stability and sealing). At the same time, a transparent plate 12 is inlaid inside the frame, and detailed scales 13 are engraved on the plate. This design enables the operator to accurately adjust the position of the line marking head 9 based on the comparison between the light projected by the laser 11 and the scale 13 plate, thus achieving a line marking accuracy of millimeter level.

[0030] The installation frame 10 adopts an inclined design, and its inclination angle can be adjusted between zero degrees and sixty degrees according to needs to adapt to the line marking requirements under different road surface conditions. In addition, the width of the installation frame 10 is also carefully designed to ensure that it matches the width of the spraying area of the line marking head 9, further improving the uniformity and aesthetics of the line marking.

[0031] The transparent plate 12 is cleverly placed on the inner retaining strip of the installation frame 10 and is tightly combined with the frame through adhesive connection, ensuring both the clear visibility of the scale 13 and avoiding displacement caused by vibration and other reasons.

[0032] Through its delicate design and reasonable layout, this automatic line marking device for hot melt road markings realizes efficient and precise line marking operations, providing a strong guarantee for the safety and smoothness of road traffic.

[0033] Working process: The operator pours the hot melt marking material into the material bucket 3 and ensures that it is filled to an appropriate level. Check whether the connections of all components are tight, including the feeding pump 5 and the connecting pipe 6, the conveying hose 7 and the marking head 9, etc., to ensure no leakage. Use the moving wheels 4 to move the equipment to the position where marking is required and make fine adjustments to ensure stability. Turn on the power of the feeding pump 5, and the pump starts to work, sucking the hot melt marking material from the material bucket 3 through the connecting pipe 6. The material is transmitted through the conveying hose 7 to the marking head 9, ready for marking.

[0034] According to the road conditions and marking requirements, the operator adjusts the tilt angle of the mounting frame 10 and the position of the marking head 9 within the U-shaped frame 8 to achieve the best marking effect. Turn on the heating function of the marking head 9 to make the hot melt material reach an appropriate fluidity and adhesion. Push the equipment or control the equipment to move along the predetermined route, and the marking head 9 will evenly spray the hot melt material on the road surface to form a clear marking.

[0035] The operator compares the light projected by the laser 11 with the scale 13 on the transparent plate 12 to observe in real time whether the marking position is accurate. If any deviation is found, immediately adjust the position of the marking head 9 within the U-shaped frame 8 or use the moving wheels 4 for fine adjustment to ensure the marking accuracy. Regularly check the marking quality and the material supply situation to ensure the continuous and stable progress of the marking operation.

[0036] After completing the marking task, turn off the power of the feeding pump 5 and the marking head 9, and disconnect the connections of all components; clean the components such as the material bucket 3, the connecting pipe 6, the conveying hose 7, and the marking head 9 to remove the residual hot melt material. Move the equipment to a safe area for storage, ready for the next use.

[0037] During observation and adjustment: Before starting the marking, observe whether the light projected by the laser 11 is aligned with the scale 13 on the transparent plate 12 to ensure the accurate initial position. During the marking process, continuously observe the position, width, and uniformity of the hot melt material sprayed by the marking head 9 on the road surface. At the same time, use the laser 11 and the scale 13 plate for position correction to ensure the marking accuracy. If any problems such as the deviation of the marking position or inconsistent width are found, immediately stop the marking operation. Solve the problem by adjusting the position of the marking head 9 within the U-shaped frame 8, the tilt angle of the mounting frame 10, or using the moving wheels 4 for fine adjustment. After the adjustment is completed, conduct a marking test again to verify the adjustment effect. After the marking is completed, conduct a comprehensive inspection of the marking quality. This includes aspects such as the clarity, adhesion, and width consistency of the marking. If any unqualified points are found, they should be repaired or re-marked in a timely manner.
