1. Brush type

刷式涂布機是比較古老的涂布設備，在19世紀50年代用于使用瓷土涂料生產涂布墻壁紙。刷式涂布頭有三種不同的類型：圓刷涂布頭、毯輥涂布頭和毯套涂布頭。

The brush coating machine is a relatively ancient coating equipment used in the 1850s to produce coated wall papers using porcelain clay coatings. There are three different types of brush type coating heads: circular brush coating heads, blanket roller coating heads, and blanket sleeve coating heads.

2、氣刀

2. Air knife

20世紀30年代氣刀涂布機的出現標志現代紙張涂布工業的誕生。氣刀涂布機克服了刷式涂布機的缺點，迅速被推廣，涂布紙產量急劇增加。

The emergence of air knife coating machines in the 1930s marked the birth of modern paper coating industry. The air knife coating machine overcomes the shortcomings of the brush coating machine and is quickly promoted, resulting in a sharp increase in the production of coated paper.

3、刮刀式

3. Scraper type

20世紀50年代出現了刮刀式涂布機。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。

In the 1950s, a scraper type coating machine emerged. Since then, the technology of scraper coating machines has developed rapidly. According to the different feeding equipment, scraper types, and scraper installation positions, scraper coating heads are also divided into many types, such as hard blade scraper coating machines, drag blade scraper coating machines, soft blade scraper coating machines, fountain type feeding scraper coating machines, short dwell scraper coating machines, Bill scraper coating machines, scraper roller coating machines, etc.

4、輥式

4. Roller type

輥式涂布是用涂布輥向涂布面施以涂料，機內涂布以這種涂層機為主。涂布量可通過計量輥間壓力進行調節，壓力增強，涂布量減少。

Roller coating is the process of applying paint to the coating surface using a coating roller, and this type of coating machine is mainly used for internal coating. The coating amount can be adjusted by measuring the pressure between the rollers, increasing the pressure and reducing the coating amount.

5、噴霧涂布

5. Spray coating

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，對紙或紙板進行單面或雙面涂布。

Spray coating technology is a non-contact coating method. Controlled high-pressure spray technology is used to coat paper or paperboard on one or both sides.

6、簾式涂布

6. Curtain coating

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，并能夠在不均勻的紙張表面上獲得均勻的涂層。

The multi-layer curtain coating machine can endow the surface of inkjet printing paper with a three-layer structure and obtain a uniform coating on uneven paper surfaces with just one coating operation.

7、狹縫式涂布

7. Slit coating

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。

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 section is used to control the operation of the pump and nozzle, and the pressure detection section is used to detect pipeline pressure. When the pressure reaches the predetermined pressure condition, the nozzle discharges the coating liquid.
