Description

Technical Field

[0001] The utility model relates to the technical field of plastic runway paving, in particular to an adjustable plastic runway marking machine. Background Art

[0002] Road marking machines are widely used in road construction applications, marking various restrictions, guidelines, and warnings on smooth surfaces. These machines, with their speed, efficiency, and accuracy, have played a significant role in urban planning and highway construction, significantly reducing both construction time and investment. After the plastic track is laid, it needs to be marked on the plastic track. The marking machine sprays the paint on the plastic track through a spray pipe to achieve the purpose of marking. After searching, the patent with publication number CN220079690U discloses a marking machine for a plastic track. When in use, the paint is added to the inside of the cylinder through a feeding pipe, and the stirring motor is started. The stirring motor drives the rotating shaft and the stirring rod to rotate, and the paint with unbroken particles is stirred again to reduce the amount of particles in the paint. The electric push rod is controlled to extend or retract, and the angle of the nozzle is adjusted to improve the flexibility of spraying and marking. The extraction pump is started to extract the paint and spray it through the nozzle. However, it is not convenient to adjust the spray width, and the edges are prone to shallow spraying. For this reason, an adjustable plastic track marking machine is designed to facilitate adjustment of the spray width, improve the applicable range of the spray width, ensure the clarity of the marking edge, and spray smoothly.

It also includes an adjustment motor 9 fixedly mounted on the bottom of the barrel 1 and used to drive the drive shaft to rotate. Start the adjustment motor 9 to make the output shaft of the adjustment motor 9 rotate clockwise or counterclockwise. Through the cooperation of the synchronous belt 11 and the two gears 10, it is easy to drive the two baffles 8 to move to the middle or to both sides at the same time, thereby adjusting the spray line width and making the line edge clear.
