Enclosed doctor blade systems (sometimes called chambered doctor blade) are designed to improve print quality, productivity, andreduce ink usage and solvent emissions in the workplace.It has a wide range of application scenarios and can carry a variety of printing liquids. Let's learn about the JCTPRINT chamber doctor blade system.
Benefits of having a doctor blade chamber
Makes the ceramic anilox roller mesh evenly filled, it makes the prints look great and eliminates the problem of color enhancement by increasing the printing speed of the old rubber pressure roller printing system, allowing more ink to pass through as the speed increases.Stable printing quality, submission work efficiency and cost saving.
Scope of application
Applicable industries: printing (flexo printing, gravure printing), varnishing, coating, compounding.
Applicable liquid: water-based ink, UV ink, solvent ink, varnish, glue.
Applicable speed:≤400m/min
Advantages of JCTPRINT
Exclusive design for customers
When we design the angle, we will formulate a reasonable angle according to the customer's circular anilox roller. Whether the squeegee angle matches or not is related to the cleanliness of the squeegee and the service life of the squeegee. The straightness of the squeegee is a key parameter in the manufacture of squeegee doctor blades. Our straightness is 0.03mm per meter. This parameter is a reflection of the final performance of material quality, processing and heat treatment.
Increase work efficiency
Equipped with a high-pressure cleaning system, adopts a sliding installation method, and an ingeniously designed airtight chamber turning mechanism, which can easily realize the 90° turning of the airtight chamber, quick cleaning, and improved work efficiency
Precisely adjusted wear reduction
The contact pressure of the doctor blade is controlled by the air bag, which is easy to adjust, which can reduce the wear rate of the ceramic roller, and at the same time ensure the printing effect and safety. The system is equipped with a constant-voltage power-off protection valve to ensure that the airbag works under constant internal pressure.
Selected raw materials
Thick aluminum alloy material is selected, and the doctor blade cavity and doctor blade holder are made of aluminum extrusion
mold, which is light in weight, good in appearance, high in precision, nickel-plated on the knife holder, and corrosion-resistant.
Master Printing Details
Equipped with segment fine-tuning function, it can adapt to the printing needs of different details on a piece of paper. The scraping method is that only the lower scraper is available, ink is fed into the middle of the ink chamber, ink is automatically discharged from both sides, and there is no internal pressure to ensure uniform ink flow. In addition, the system also has an ink return tank to effectively prevent ink from leaking out.
Application Scenario
It is the preferred choice for many customers to improve printing quality and work efficiency
