Description

Technical Field

[0001] The utility model relates to the technical field of melting devices, in particular to a melting device for hot-melt road marking paint. Background Art

[0002] Thermoplastic road marking paint is a kind of paint applied on the road to mark road markings. Road markings are a kind of safety mark and a silent "language" in highway traffic. Thermoplastic road marking paint is a solid powder at room temperature. During construction, the paint needs to be melted.

[0003] At present, when hot-melt marking paint is melted, after the existing cylinder is stirred, a large amount of paint is easily adhered to the inner wall of the cylinder and cannot be discharged, which easily causes waste of paint. When the temperature inside the cylinder drops, it is also difficult to clean the cooled paint. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a hot melt marking paint melting device, which overcomes the deficiencies of the prior art and effectively solves the problem in the prior art that after stirring, a large amount of paint is easily adhered to the inner wall of the cylinder and cannot be discharged, which easily causes waste of paint, and when the temperature inside the cylinder drops, it is not easy to clean the cooled paint.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hot melt marking paint melting device comprises a cylinder, a top cover is connected to the top of the cylinder, and a cover plate is hinged on the outer wall of one side of the top cover, a servo motor is installed on the top of the top cover, and the output shaft of the servo motor is connected to a stirring mechanism, the stirring mechanism comprises a stirring rod, a telescopic assembly symmetrically fixed to the two ends of the stirring rod wall and a scraper arranged on both sides of the stirring rod, the telescopic assembly comprises a fixed cylinder, a telescopic spring connected to the fixed cylinder and an insertion rod inserted in the fixed cylinder.

[0007] By opening the cover, the raw materials of the paint and water are added into the cylinder. After the cover is closed, the output shaft of the servo motor drives the connected stirring rod to rotate, and the heater increases the water temperature in the cylinder to fully stir and mix the raw materials of the paint and the warm water. During the stirring process, the stirring rod drives the scraper to scrape the inner wall of the cylinder to prevent the paint from adhering to the inner wall and accumulating. During the discharge process, the servo motor drives the stirring rod to rotate slowly, so that the scraper slowly scrapes the inner wall of the cylinder, thereby scraping the paint on the inner wall of the cylinder downwards.

[0008] Preferably, the annular outer wall of the cylinder is fixed with support blocks distributed at equal distances, and the bottoms of the support blocks are fixed with support rods, and the bottoms of the support rods are fixed with a base.

[0009] The height of the cylinder is supported and fixed by the support blocks, support rods and base.

[0010] Preferably, a discharge pipe is plugged and fixed at the bottom of the cylinder, and a control valve is installed on the discharge pipe.

[0011] The paint in the cylinder is discharged through a discharge pipe with a control valve.

[0012] Preferably, an annular groove is provided at the bottom of the annular outer wall of the cylinder, and an annular heater is installed in the annular groove.

[0013] The temperature inside the cylinder is increased by the installed heater.

[0014] Preferably, the scraper bar is adapted to the specifications of the inner wall of the cylinder, and connecting pipes are fixed to both ends of the outer wall of the scraper bar on one side close to the stirring rod.

[0015] The rotation of the stirring rod drives the two scraping bars to rotate in the cylinder, thereby scraping the paint on the inner wall of the cylinder downward, which is beneficial to full utilization of the paint in the cylinder and also beneficial to cleaning the inner wall of the cylinder.

[0016] Preferably, one end of the insertion rod is connected and fixed to one end of the telescopic spring, and the other end of the insertion rod is plug-fitted to the connecting pipe.

[0017] The expansion and contraction of the expansion spring facilitates the plugging and connection of the plug rod and the connecting pipe, thereby facilitating the replacement and cleaning of the scraper strip.

[0018] The beneficial effects of the utility model are:

[0019] The cover is opened, the raw materials of the paint and water are added into the cylinder, and after the cover is closed, the output shaft of the servo motor drives the connected stirring rod to rotate. During the stirring process, the stirring rod drives the scraper to scrape the inner wall of the cylinder, thereby preventing the paint from adhering to the inner wall and accumulating. During the discharging process, the servo motor drives the stirring rod to rotate slowly, so that the scraper slowly scrapes the inner wall of the cylinder, thereby scraping the paint on the inner wall of the cylinder downwards, which effectively solves the problem in the prior art that after stirring, a large amount of paint is easily adhered to the inner wall of the cylinder and cannot be discharged, which easily causes waste of paint, and when the temperature in the cylinder drops, it is not easy to clean the cooled paint.
