1. Moveable blade device.
2. Guiding roller in oven will synchronously rotates with main shaft.
3. Solenoid operated valve controlling is adopted for Anilx roller and drawing roller.
4. Automatic meter-measuring devices.
5. Key mode air shaft is used for unwinding and rewinding shafts, easy to load and unload.
four. Development of technology and efficiency products
However, in the face of the future, although it is impossible to comprehensively predict the development status of the tape industry or variety, the preconditions and planning blueprints are tightly bundled in the standard application specification of the processing application and adhesive arrangement combined with the medium. For example, new technology products automotive insulation paper (wear, light, sun, heat insulation), PVB color glass tape (color decoration, heat insulation, noise, earthquake blasting), environmentally friendly waterproof coating film (Computer drawing water ink compatible, waterproof and wearable), highway refraction film glass microbead composite tape (eye-catching refraction, temperature resistance, cold resistance, freeze resistance, acid resistance, anti-aging), digital camera waterproof high gloss photo paper (computer drawing water The development, processing and manufacturing of products such as ink compatibility, waterproof and abrasion resistance, high resolution, high reductiveness and long shelf life are all applications of media surface treatment technology. On the other hand, such as; aerospace equipment without media double-sided tape (high temperature resistant film), medical conductive tape (heart pulse electric shock and medical detector fixed), printed circuit board composite tape (high temperature, impact resistance), car Interior decorative panel (high temperature resistance, buffer safety, aesthetics), road marking tape (eye-catching, temperature-resistant, cold-resistant, freeze-resistant, acid-resistant, anti-aging), correction tape (shading, writing, ink absorption) (Sex), anti-counterfeiting and brittle tape (easy brittle, anti-counterfeiting, printing, shielding) and other products are subject to the technical transformation of the adhesive. However, if the basic structure of the two types of products is carefully summarized, the technical results formed on the basis of the adhesive application are only the technical process differences between the application process and the treatment, and the main surface function of the medium surface treatment or the adhesive is distinguished. In fact, most of the technical applications of various types of tape products are based on the application and function of adhesives.
Characteristics of several coating methods -
Stainless steel scraper
The scraper is sheared by a stainless steel sheet and pressed against the blade holder and applied to the upper (coating) rubber roller. Since the stainless steel sheet is soft, the squeegee is not very uniform, and most of the squeegee used on the anilox roll is also used for pre-scraping of the glazing coating.
Such scrapers are often made of round steel with good strength and hardness. The blade is fixed and does not rotate when the glue is scraped. The strength of the scraper is high, the hardness of the blade is small, and the pneumatic and fine adjustment mechanism can be used to adjust and control the position of the scraper. The coating amount control and the scraping precision are high, and the use is also extremely convenient. Due to its uniform squeegee, it is suitable for precise squeegee coating on smooth rolls.
This type of scraper is usually made of round rods with good strength and hardness. The round bar is required to rotate when scraping the glue. Sometimes the bar can also be scraped directly onto the substrate. The full runout error of the scraper bar is very small, and it is mostly used for the pre-squeegee coating of the glue bar coating on the light roller. When the glue is sticky, it can also be directly scraped on the substrate with a scraper as a precise scraping agent for the coating mechanism. It can also be used for coating a thicker disposable squeegee.
