Description

Technical Field

[0001] The invention belongs to the technical field of road marking machines, and in particular relates to a fully automatic road tracking hot-melt road marking machine. Background Art

[0002] Thermoplastic road marking machines, core equipment for modern road marking, utilize a scraping and molding process using high-temperature, molten powdered paint (200°C). Their application quality directly impacts the durability and safety of road traffic signs. With the advancement of intelligent technology, fully automatic road-tracking thermoplastic road marking machines have evolved into comprehensive solutions integrating intelligent navigation, automatic trajectory tracking, thermoplastic spraying, and precision control systems. These machines are widely used in road marking applications across highways, urban road networks, parking lots, and other locations.

[0003] In existing technologies, pavement pretreatment in traditional construction processes relies entirely on manual cleaning, which not only increases labor costs but also forms an interface weakening layer due to pollutants such as residual particulate matter and floating impurities on the road surface, resulting in a decrease in the adhesion of the markings and a serious shortening of the marking service life. In addition, not only is it inconvenient to perform real-time manual cleaning, but the impurities removed from cleaning can easily affect the position of adjacent freshly marked lines, causing damage to the markings. More notably, the bumps in the equipment caused by road impurities can cause the marking bucket to vibrate, causing the markings to fluctuate, directly affecting the visual continuity of road safety signs.

[0004] Therefore, it is necessary to invent a fully automatic road tracing hot melt marking machine to solve the above problems. By constructing a closed-loop construction system of "detection-cleaning-marking", it can fundamentally solve the common industry problems existing in traditional processes, such as unstable construction quality, high dependence on manual labor, and difficulty in optimizing comprehensive costs.

[0016] Technical effects and advantages of the present invention: 1. The present invention uses a positioning column inserted through the inner wall of the positioning groove to move horizontally, so that the two ends of the connecting rod are respectively rotatably connected to the positioning rod fixed on the top of the rotating plate, so that the moving frame drives the two rotating plates to rotate synchronously in the same direction while moving. The blower fixed on one side of the positioning frame works, so that the blower blows air obliquely downward to the ground through the setting of the connecting pipe for cleaning. The two rotating plates are oriented so that the dust and impurities blown up move in the direction guided by the rotating plates, which not only cleans the ground in real time and reduces labor costs, but also allows the cleaned impurities to be cleaned in a targeted manner to avoid contaminating the adjacent markings that have just been marked. At the same time, real-time cleaning is carried out before marking to avoid the formation of an interface weakening layer of ground stains, thereby improving the adhesion of the markings and increasing the service life of the markings, and significantly reducing human intervention, thereby improving construction quality and efficiency. It is an ideal choice for intelligent road construction. 2. The present invention sequentially meshes multiple positioning gears, so that the positioning shaft fixed at the bottom of the positioning gear passes through the positioning platform and drives the multiple limit platforms to rotate, so that the cleaning brushes fixed at the bottom of the multiple limit platforms rotate and clean, so that stubborn mud and other lumps stuck on the ground can be fully cleaned. The intercepting rod fixed at the bottom of the fixed frame isolates floating impurities that accidentally enter, avoiding contamination during the marking operation, improving the adhesion of the marking, and increasing the convenience of using the fully automatic road tracing hot melt road marking machine. 3. The present invention drives the second drive gear to rotate through the output end of the third motor fixed at the bottom end of the support frame, so that the two first drive gears and the second drive gear respectively drive the two first hot melt stirring shafts and the second hot melt stirring shafts to rotate, and by controlling the operation of the solenoid valve fixed on one side of the storage barrel, the liquid level in the mixing barrel is always kept stable, and the speed of the second hot melt stirring shaft is higher than that of the first hot melt stirring shaft, so that the material is fully mixed before spraying, and the material is stored in a divided barrel manner to avoid the hidden danger of uneven material stirring caused by a storage barrel with an excessively large diameter, thereby increasing the storage capacity of the material.
