Description

Technical Field

[0001] This utility model relates to the technical field of self-luminous road markings, and in particular to a mixing device for self-luminous two-component road marking paint. Background Technology

[0002] Self-luminescent two-component road marking paint is a special type of road marking paint. It not only possesses the wear resistance and weather resistance of traditional marking paints, but also has the ability to glow in the dark, greatly improving nighttime driving safety. This paint typically consists of two components that need to be mixed in a specific ratio during application and then applied using specialized equipment such as a two-component marking machine. As a mixture, it's impossible to mix exactly what you need; generally, more is mixed than used. However, the excess may separate or contain sediment or particles that settle during subsequent uses. Existing equipment cannot fully agitate the paint at the bottom, often resulting in uneven mixing.

[0003] Chinese Patent Publication No. CN222841881U, authorized on May 9, 2025, discloses a mixer for producing self-luminous road marking paint. The mixer includes a support base with support arms extending upwards from both sides of its top. A mixing hopper is rotatably connected between the two support arms via bearings. A stirring assembly, located inside the support base, is used to mix the self-luminous road marking paint. A drive unit, located on one side of the support base, is connected to the stirring assembly for driving its rotation. The drive unit includes a drive section and a connecting section. This application, through the lifting assembly and drive unit, allows the connecting arm to be disconnected from the swing arm during the later stages of material discharge from the discharge pipe. This lifts the mixing hopper, concentrating the material and directing it towards the discharge direction. This ensures sufficient discharge of the self-luminous road marking paint from the mixing hopper, preventing large accumulations at the bottom and material waste. However, this invention has the drawback of insufficient stirring and uneven mixing. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of insufficient stirring and uneven mixing in the existing technology, and provides a mixing device for self-luminous two-component road marking paint that provides more sufficient stirring and more uniform mixing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mixing device for self-luminous two-component road marking paint includes: The mixing frame has an open top surface and an arc-shaped side cross-section of its inner bottom surface. A discharge port is provided at the lowest point of the bottom of the mixing frame, and the discharge port is connected to the interior of the mixing frame. There are two rotating rods, both placed inside the mixing frame. The rotating rods run in a front-to-back direction, and the distances between the two rotating rods and the left and right ends of the mixing frame are equal. One end of the rotating rod passes through the inner wall of the mixing frame and is placed outside the mixing frame. A rotating motor is provided on the end of the rotating rod placed outside the mixing frame. The rotating shaft of the rotating motor is fixedly connected to one end of the rotating rod. The other end of the rotating rod is placed on the other side inside the mixing frame and is rotatably connected to the mixing frame. A conveyor belt is wrapped around the outer surface of two rotating rods. The inner surface of the conveyor belt is engaged with the outer surface of the rotating rods. The conveyor belt rotates by driving the rotating rods to rotate via a rotating motor. The mixing rods are arranged in several groups, with each group containing several mixing rods. The mixing rods are perpendicular to the outer side of the conveyor belt, with one end of each mixing rod engaging with the conveyor belt. Each group of mixing rods is evenly distributed front to back, and the length of each group corresponds to the side cross-sectional shape of the bottom surface of the mixing frame. The other end of each mixing rod contacts the bottom surface of the mixing frame, and the longest mixing rod in each group contacts the left and right sides of the mixing frame during its running trajectory.

[0006] When using it, first pour the raw materials into the mixing frame, then turn on the rotating motor. The rotating rod will drive the conveyor belt to start rotating, allowing the mixing rod to touch the bottom and mix the materials, expanding the mixing area and reducing the areas that cannot be mixed. Finally, the mixed materials are released from the discharge port, achieving the purpose of more thorough mixing and more uniform mixing.

The support rod is engaged with the stirring rod through the cooperation of the slots and locking blocks. The slots and locking blocks facilitate the fixing of the stirring rod to the support rod.

[0010] Preferably, a flexible strip is provided on one end of the conveyor belt of the mixing rod. The angle between the flexible strip and the mixing rod is less than 90°, and the angle between the flexible strip and the mixing rod is consistent with the running direction of the rotating conveyor belt. The flexible strip is fixedly connected to the mixing rod, and the outer end of the flexible strip on the mixing rod contacts the inner bottom surface of the mixing frame. The flexible strip can extend the mixing length of the mixing rod without damaging or interfering with the mixing frame, and the angle between the flexible strip and the mixing rod increases the toughness of the flexible strip.

[0011] Preferably, a support strip is provided on the outer side of the mixing frame. The support strip wraps around the outer side of the mixing frame, is perpendicular to the outer side of the mixing frame, and is fixedly connected to the mixing frame. The support strip provides a support for the mixing frame to be lifted.

[0012] Preferably, the outer surface of the support strip is provided with two connecting tubes, which are symmetrically distributed front and back. The internal channels of the connecting tubes are parallel to the direction of the support strip, and the connecting tubes are fixedly connected to the support strip.
