The marking machine has various structures, which may differ in structure due to different production design conditions or application to different construction objects and different raw materials. The marking machine generally needs to have paint (melt) bucket, marking bucket (spray gun), guide rod, controller and other devices, and configure various power-assisted drive carriers as required.

Engine: Most marking machines are powered by engines, and some are powered by batteries. If the engine is used, its power is about 2, 5HP to 20HP, but it is best to be an internationally renowned brand, such as the American Briggs & Stratton, and the Japanese Honda. The advantages are self-evident: stable performance and easy to purchase parts Determines the operating performance of the entire device; if the battery is used as power, the time that can be run per charge must also be considered, preferably not less than 7 hours (about a day of work).

Air compressor: For the marking machine that relies on air to spray (not hydraulic spray), it is also the main part that affects the performance of the whole machine. Like engines, you should consider buying products equipped with internationally renowned brands of air compressors. The larger the emissions, the better, but there must be a certain limit.

Paint (melt) bucket: It has two main functions: First, it holds paint. In this sense, its capacity will affect the number of fillings and the progress of the operation. Another function that many users overlook is that the container is also a pressure container. It is pressurized by an air compressor to become a pressurized "air tank" which becomes the driving force for marking. In this sense, it The tightness, safety, and corrosion resistance should be considered by the user. The better buckets are made of stainless steel, and some products also meet the American ASME standard.
