Technical Field

[0001] The utility model belongs to the technical field of coating mixing and modifying equipment, and in particular relates to a special mixing and modifying equipment for hot-melt road marking coatings. Background Art

[0002] With the emergence of market demand for road marking functionality (anti-crack performance, aging resistance, and anti-fouling performance), in the production process of hot-melt road marking paint, it is necessary to pre-process the pigments and fillers added therein with specific surface modification, or add additional liquid modifiers to the paint to give the road markings directional function after marking.

[0003] However, the hot melt paint mixers currently used in the production of hot melt road marking paint only have the function of mixing materials. For example, Chinese patent application No. 201820263603.4 discloses a paint mixer for road marking, including a bottom box, a first motor is fixedly connected to the left side of the back side of the inner wall of the bottom box, a disc is fixedly connected to the output end of the first motor, a transmission rod is fixedly connected to the right side of the front side of the disc, a light rod is fixedly connected to the bottom of the inner wall of the bottom box, the top of the light rod is fixedly connected to the top of the inner wall of the bottom box, a slip ring is slidably connected to the surface of the light rod, a transmission frame used in conjunction with the transmission rod is fixedly connected to the left side of the slip ring, the surface of the transmission rod is slidably connected to the inner wall of the transmission frame, a connecting plate is fixedly connected to the right side of the slip ring, a movable rod is fixedly connected to the front side of the connecting plate, a guide groove is provided at the bottom of the inner wall of the bottom box, and a guide groove is slidably connected inside the guide groove. The guide block is fixedly connected with a vertical plate at the top, and an oblique hole used in conjunction with a movable rod is provided on the front of the vertical plate. A connecting rod is fixedly connected with the top of the vertical plate, and the top of the connecting rod passes through the bottom box and extends to the outside of the bottom box and is fixedly connected with a mixing box. The two sides of the bottom of the mixing box are fixedly connected with a first slide bar, and a first slide groove is provided at the top of the bottom box and corresponding to the position of the first slide bar. The first slide bar is slidably connected with the first slide groove, and the top of the mixing box is fixedly connected with a second motor, and the output end of the second motor passes through the mixing box and extends to the inside of the mixing box and is fixedly connected with a rotating shaft, and both sides of the rotating shaft are fixedly connected with stirring rods, and a feed port is provided on the left side of the top of the mixing box, and a discharge pipe is connected to the bottom of the right side of the mixing box, and a valve is provided on the top of the discharge pipe. The paint mixer for road marking has the advantage of efficient mixing. For another example, Chinese patent application No. 201920408630.0 discloses a paint stirring device for a road marking vehicle, comprising a mounting base and a stirring barrel, mounting holes are provided on both ends of the outer walls of the mounting base, and side columns are welded to the outer walls on both sides of the top of the mounting base, a second fixed seat is welded to the bottom outer wall of one side of the side column, and a second motor is arranged on the top outer wall of the second fixed seat, a rotating shaft is welded to the output shaft of the second motor, and a driving bevel gear is welded to the outer wall of the rotating shaft, a driven bevel gear is welded to the middle position of the outer wall of the stirring barrel, and a tooth chain is arranged on the outer wall of the driven bevel gear and the outer wall of the driving bevel gear, a first motor is arranged on the top outer wall of the stirring barrel, and a rotating rod is welded to the output shaft of the first motor, stirring shafts distributed equidistantly are welded to the outer wall of one side and the outer walls of both ends of the rotating rod, and an inclined plate is welded to the outer wall of the other side of the rotating rod, a fixed cylinder distributed equidistantly is welded to the bottom of the outer wall of the rotating rod, and a buffer rod is inserted into the inner wall of the fixed cylinder, and a spring is welded to the outer wall of one side of the buffer rod and the inner wall of the fixed cylinder.The paint stirring device creates the effect of the stirring barrel rotating itself, which preliminarily improves the stirring effect of the paint, and uses the inclined plate to scrape off the paint attached to the inner wall of the stirring barrel to avoid the paint adhering to the inner wall of the stirring barrel and causing paint waste, and uses the convex block and the two sides of the fixed plate to swing to efficiently mix the paint.

[0004] When using existing paint mixing equipment, on the one hand, the liquid additives in the paint can only be directly poured into the mixing chamber for mixing, resulting in low mixing efficiency; on the other hand, if you want to produce high-functional hot-melt road marking paint, you need to equip it with an additional modification equipment, that is, the raw materials such as calcium carbonate, quartz sand, titanium dioxide and glass beads are surface-modified in the modifier, and then transferred to the hot-melt paint mixer to mix with the resin and other additives, which not only increases the modification cost of the color and filler, but also takes up space and consumes manpower and material resources.

[0015] A heating component is added to the bottom of the mixing bin of the original hot melt paint mixer to improve the modification effect of the pigment and filler and shorten the drying time of the modified filler.
