1、刷式
1. Brush type
刷式涂布机是比较古老的涂布设备，在19世纪50年代用于使用瓷土涂料生产涂布墙壁纸。刷式涂布头有三种不同的类型：圆刷涂布头、毯辊涂布头和毯套涂布头。
The brush coating machine is a relatively old coating equipment, which was used in the 1850s to produce coated wall wallpaper with porcelain clay coating. There are three different types of brush applicator: round brush applicator, blanket roller applicator and blanket cover applicator.
2、气刀
2. Air knife
20世纪30年代气刀涂布机的出现标志现代纸张涂布工业的诞生。气刀涂布机克服了刷式涂布机的缺点，迅速被推广，涂布纸产量急剧增加。
The appearance of air knife coater in the 1930s marked the birth of modern paper coating industry. The air knife coater has overcome the shortcomings of the brush coater and has been rapidly promoted, resulting in a sharp increase in the output of coated paper.
3、刮刀式
3. Scraper type
20世纪50年代出现了刮刀式涂布机。此后刮刀涂布机技术得到了快速的发展。根据上料设备、刮刀类型和刮刀安装位置的不同，刮刀涂布头也分为许多种，如硬刃刮刀涂布机、拖刀式刮刀涂布机、软刃刮刀涂布机、喷泉式上料刮刀涂布机、短驻留刮刀涂布机、比尔刮刀涂布机、刮辊式涂布机等。

In the 1950s, a scraper coater appeared. Since then, the technology of scraper coater 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、辊式
4. Roller type
辊式涂布是用涂布辊向涂布面施以涂料，机内涂布以这种涂层机为主。涂布量可通过计量辊间压力进行调节，压力增强，涂布量减少。
Roller coating is to apply coating to the coating surface with the coating roller, and the coating machine is mainly used for internal coating. The coating amount can be adjusted by measuring the pressure between the rollers. The pressure increases and the coating amount decreases.
5、喷雾涂布
5. Spray coating
喷雾涂布技术是一种非接触涂布方式，采用可控高压喷雾技术，对纸或纸板进行单面或双面涂布。
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、帘式涂布
6. Curtain coating
多层帘式涂布机只需经过一次涂布操作，就能够赋予喷墨打印纸表面三层结构，并能够在不均匀的纸张表面上获得均匀的涂层。
The multi-layer curtain coater can endow the ink-jet printing paper with a three-layer structure after only one coating operation, and can obtain a uniform coating on the uneven paper surface.
7、狭缝式涂布
7. Slit coating
狭缝涂布头包括，涂布液储存罐；泵，用于将涂布液储存罐里的涂布液通过供给管路压送到喷嘴处；控制部，用于控制泵及喷嘴的的工作，压力检测部，用于检测管路压力，当压力达到预定压力条件时喷嘴排除涂布液。
The slit coating head comprises a coating liquid storage tank; The pump is used to press the coating liquid in the coating liquid storage tank to the nozzle through the supply pipeline; The control part is used to control the operation of the pump and nozzle, and the pressure detection part is used to detect the pipeline pressure. When the pressure reaches the predetermined pressure condition, the nozzle discharges the coating liquid.
