What is Road Marking Machine?

Road marking machine is a kind of device specially used to delineate diverse traffic lines on blacktop or concrete surfaces in order to offer guidance and information to motorists and pedestrians. Regulation for parking and stopping can also be indicated by the traffic lanes. Line marking machines conduct their work through screeding, extruding, and spraying thermoplastic paints or cold solvent paints onto the pavement surface.

Some Important topics related to Road Marking Machines are:

  • Concept of Road Marking Machine
  • Types of Road Marking Machines
  • How Does Road Marking Machine Work?

Concept of Road Marking Machine

Road marking machine herein means the aggregate of hand-push type machine, self-propelled type machine, sitting type machine, thermoplastic type machine, and cold painting type machine, which is used to mark a line on the road. It is mainly used in car parks, avenues, streets, highways, etc. contributing to improving the convenience and safety of driving and walking.

Types of Road Marking Machines

Based on the different driving modes, which is also a typical classification principle, all the pavement stripe markers can be categorized into hand-push type(also called walk behind stripping machines), self-propelled typedriving-type, and truck-mounted type.

A thermoplastic pavement marking machine is a low-pressure air spraying machine with high efficiency and flexibility. It can serve long-distance and continuous line marking work. The spray thickness is adjustable and not affected by the old marking line. A hot melt kettle inside the machine plays a vital role in heating, melting, and stirring thermoplastic marking paints. The coating only needs a few minutes to harden after cooling fast from 200℃. Thermoplastic paints can be produced in any color, but when it comes to road marking, yellow and white are the most common colors.

Two-component line marking machine is high-end marking equipment that has emerged in recent years. Unlike thermoplastic marking facilities and cold paint airless pavement marking equipment which coats the road with paint film through physical drying methods such as temperature drop or solvent volatilization, the two-component marking is a new type of striping device that forms a coating film by internal chemical cross-linking.

How does Road Marking Machine Works?

First, put the paint into the thermal insulation bucket for melting, and then introduce the melted liquid thermoplastic paint into the marking hopper and keep it in a flowing status. When starting to draw the line, put the marking hopper on the road, leaving a certain gap between the marking hopper and the ground. When the marking machine moves straight forward at a constant speed, it will automatically delineate a neat marking line. The glass bead spreader can automatically and evenly spread a layer of reflective glass beads on the marking line.

Briefly, In terms of thermoplastic type machine, at first, we need to heat and mix the paint within the thermoplastic pre-heater, and then put the paint into the paint tank of thermoplastic type device, then we can drive this machine to mark line: Paint from the paint tank out, after crossed the marking shoes, ultimately falls on the road.

In terms of cold print type machines, we needn’t heat and mix the paint. Only put the paint into the paint tank of the cold paint type machine, then we can drive this machine to the marked line: Paint is pumped from the paint tank after crossing the marking shoes, ultimately falls on the road.
