In the advertising industry, graphic cutting machines are frequently used core equipment, widely applied for the precise cutting of materials such as KT boards, PVC boards, acrylic, stickers, photo films, self-adhesive paper, and reflective films. To maintain high precision and efficiency during long-term operation, regular maintenance and cleaning are essential. So, do advertising graphic cutting machines need cleaning? And how should they be cleaned scientifically? The following content will explain this in detail.

Why do we need to clean advertising packaging cutting machines?

1. To ensure cutting/printing accuracy: Accumulated dust and material debris (especially after cutting) can interfere with the normal operation of sensors, leading to inaccurate machine positioning and material waste.

2. To prevent material scratches: Hard objects or debris adhering to the rollers can scratch expensive inkjet printing materials or self-adhesive materials during paper feeding.

3. To avoid inkjet printer printhead clogging: Environmental dust is one of the main causes of printhead clogging in inkjet printers. Keeping the machine clean, especially the printhead carriage and platform area, is crucial.

4. To maintain mechanical performance: Dirt on the guide rails and lead screws accelerates wear, affects the smoothness of machine movement, and in the long run, can lead to decreased accuracy or even damage.

5. To prevent static electricity and electrical malfunctions: Excessive dust accumulation can cause short circuits or other electrical problems on circuit boards.

Which areas need cleaning and how should they be cleaned?

The power must be disconnected before cleaning!

Optical sensors

Location: Typically located near the pressure roller, it is a small, usually transparent component containing an LED and a receiver.

Reason for Cleaning: It is responsible for reading the material's markers (positioning points) and detecting material boundaries. If covered in dust, the machine will be unable to recognize these markers, resulting in errors such as "marker not found."

Method: Use an airbag or blower to remove surface dust. Gently wipe the sensor surface with a cotton swab dampened with a small amount of industrial alcohol or electronic cleaner. Never wipe directly with a cloth to avoid leaving fibers.

Feed rollers and pressure rollers

Location: The main metal shaft and rubber rollers inside the machine.

Reason for cleaning: They are in direct contact with the material surface. Adhesive residue and material debris on them can cause slippage during feeding or scratch the back of the material.

Method: Use a non-woven or soft cloth dampened with a small amount of water or alcohol. Rotate the rollers by hand while wiping the entire surface with the cloth until all stains are removed. For stubborn adhesive residue, use a specialized adhesive remover, but be sure to ensure it does not corrode the rubber rollers.

Guide rails and lead screws

Location: The metal rod of the moving cutter head.

Why clean it: Dust mixed with old lubricating oil forms sludge, hindering movement and accelerating wear.

Method: First, remove larger dust and debris with a soft-bristled brush or hair dryer. Then thoroughly clean the guide rails and leadscrew with a non-woven cloth dampened with alcohol or a specialized guide rail cleaner.

Key Step: After cleaning and thorough drying, a thin, even layer of specialized guide rail lubricant must be applied. Never use ordinary machine oil, as it will attract more dust and may damage components.

Cutting head

Location: Moving carriage section.

Reason for cleaning: Sticker residue tends to accumulate around the cutter head; the printhead holder may be stained with ink or contaminated with dust.

Method: Cutter: Carefully remove all debris around the cutter head with a small brush. Photo printer: Gently wipe the bottom of the carriage with a non-woven cloth dampened with cleaning solution, being careful not to directly contact the printhead.

Work surface

Use a vacuum cleaner or air gun to remove dust and debris. Regularly unclog the suction holes with a fine needle to ensure smooth vacuum suction.

Depending on the frequency of use and the environment, the cleaning cycle can be referenced as follows:

In addition, a comprehensive maintenance should be performed every 3 to 6 months, including guide rail lubrication, vacuum system inspection, and tool head cleaning and calibration.

Regular cleaning is not an option, but a necessary step to ensure the long-term stable operation of machines.

Spending just ten minutes cleaning can keep equipment in optimal condition for extended periods, creating more efficient and precise productivity for your business.
