1、刷式：刷式涂布機是古老的涂布設備，初于19世紀50年代用于使用瓷土涂料生產涂布墻壁紙。刷

1. Brush type: The brush type coating machine is an ancient coating equipment, originally used in the 1850s to produce coated wall papers using porcelain clay coatings. brush

式涂布頭有3種不同的類型：圓刷涂布頭、毯輥涂布頭和毯套涂布頭。圖1為一種早期使用的刷式涂布頭。

There are three different types of coating heads: round brush coating heads, blanket roller coating heads, and blanket sleeve coating heads. Figure 1 shows an early brush type coating head.

2、氣刀：20世紀30年代氣刀涂布機的問世標志著現代紙張涂布工業的誕生。氣刀涂布機正是克服了刷式涂布機的上述缺點，迅速被推廣，導致了涂布紙產量的急劇增加；

2. Air knife: The emergence of air knife coating machines in the 1930s marked the birth of modern paper coating industry. The air knife coating machine has overcome the above-mentioned shortcomings of brush coating machines and has been rapidly promoted, leading to a sharp increase in the production of coated paper;

3、刮刀式：20世紀50年代出現了個刮刀式涂布機專利。此后刮刀涂布機技術得到了快速的發展。根據上料設備、刮刀類型和刮刀安裝位置的不同，刮刀涂布頭也分為許多種，如硬刃刮刀涂布機、拖刀式刮刀涂布機、軟刃刮刀涂布機、噴泉式上料刮刀涂布機、短駐留刮刀涂布機、比爾刮刀涂布機、刮輥式涂布機等；

3. Scraper type: In the 1950s, a patent for a scraper type coating machine emerged. Since then, the technology of scraper coating machines has developed rapidly. According to the different feeding equipment, scraper type, and scraper installation position, the scraper coating head is also divided into many types, such as hard blade scraper coating machine, drag blade scraper coating machine, soft blade scraper coating machine, fountain type feeding scraper coating machine, short dwell scraper coating machine, Bill scraper coating machine, scraper roller coating machine, etc;

4、輥式：輥式涂布是用涂布輥向涂布面施以涂料，機內涂布以此類涂布機為主。涂布量可通過計量輥間壓力進行調節，壓力加強，涂料的通過量減少，涂布量也就減少。輥式涂布機的類型：壓榨輥式涂布頭、逆轉輥式涂布頭、傳遞輥式涂布頭、凹版輥式涂布頭；

4. Roller type: Roller type coating is a type of coating machine that uses a coating roller to apply paint to the coating surface, and the main coating machine is this type of coating machine. The coating amount can be adjusted by measuring the pressure between the rollers. When the pressure is increased, the amount of paint passing through is reduced, and the coating amount is also reduced. The types of roller coating machines include: press roller coating head, reverse roller coating head, transfer roller coating head, and concave roller coating head;

5、噴霧涂布：噴霧涂布技術是一種非接觸涂布方式，采用可控高壓噴霧技術可對紙或紙板進行單面或雙面涂布（施膠）；

5. Spray coating: spray coating technology is a non-contact coating method. Controlled high-pressure spray technology can be used to coat paper or paperboard on one or both sides (glue);

6、簾式涂布：多層簾式涂布機只需經過一次涂布操作就能夠賦予噴墨打印紙表面三層結構(底層、吸收層

6. Curtain coating: The multi-layer curtain coating machine can endow the surface of inkjet printing paper with a three-layer structure (bottom layer, absorption layer) through only one coating operation

和頂層)，并能夠在不均勻的紙張表面上獲得均勻的涂層；

And can obtain a uniform coating on uneven paper surfaces (with the top layer);

7、狹縫式涂布：狹縫涂布頭包括，涂布液儲存罐；泵，用于將涂布液儲存罐里 的涂布液通過供給管路壓送到噴嘴處；控制部，用于控制泵及噴嘴的的工作，壓力檢測部，用于檢測管路壓力，當壓力達到預定壓力條件時噴嘴排除涂布液。

7. Narrow seam coating: The narrow seam coating head includes a coating liquid storage tank; Pump, used to press the coating liquid in the coating liquid storage tank to the nozzle through the supply pipeline; The control department is used to control the operation of the pump and nozzle, and the pressure detection department is used to detect pipeline pressure. When the pressure reaches the predetermined pressure condition, the nozzle discharges the coating liquid.
