保温铝卷涂料涂装是生产线的核心部分,主要设备包括辊涂机和烘道,一般采用正面或正反面涂装的工艺,根据涂布辊和传动辊的进行方向的不同,可分为顺涂和逆涂俩种工艺。
Thermal insulation aluminum coil coating is the core part of the production line. The main equipment includes roller coating machine and drying channel. Generally, the front or front and back coating process is adopted. According to the different direction of coating roller and transmission roller, it can be divided into forward coating and reverse coating processes.
保温铝卷涂装设备辊涂机是利用辊筒将涂料涂布在卷铝上的一种设备,应用较多的是双辊机和三辊机。双辊机主要由漆槽、提料辊、涂布辊、传动辊组成。工作时,将事先调整好的涂料由工作泵打入漆槽,提料辊负责将漆槽中的涂料粘起并转移到涂布辊上,涂布辊将涂料涂布在传动中的卷铝上,传动辊主要负责金属卷材的传动。
Thermal insulation aluminum coil coating equipment roller coating machine is a kind of equipment that uses roller to coat coating on aluminum coil. Double roller machine and three roller machine are widely used. The double roller machine is mainly composed of paint tank, lifting roller, coating roller and transmission roller. During operation, the paint adjusted in advance is pumped into the paint tank by the working pump. The lifting roller is responsible for gluing the paint in the paint tank and transferring it to the coating roller. The coating roller applies the paint to the aluminum coil in the transmission, and the transmission roller is mainly responsible for the transmission of metal coil.

实际操作过程中,提料辊、涂布辊、传动辊之间的相对转动速度有一定的比例。与双辊机相比三辊机多一个控制辊,控制辊是用来调节由提料辊转移到涂布辊上的涂料的量,对于准确控制涂漆量有一定的作用。如果三个辊筒之间的转动速度比例不合理,涂布出来的材料会产生横条纹和竖条纹等表面问题。一般情况下,三个辊筒的筒面线速度大小:合理控制保温铝卷三个辊筒转动速度和相互之间的比例是涂布出有良好外观涂膜的关键因素之一,三辊机主要应用在表面要求高的场合。
In the actual operation process, the relative rotation speed between the lifting roller, coating roller and transmission roller has a certain proportion. Compared with the two roll machine, the three roll machine has one more control roll. The control roll is used to adjust the amount of paint transferred from the lifting roll to the coating roll, which plays a certain role in accurately controlling the amount of paint. If the rotation speed ratio between the three rollers is unreasonable, the coated material will have surface problems such as horizontal stripes and vertical stripes. In general, the linear speed of the three rollers: reasonably controlling the rotation speed of the three rollers and the proportion between them is one of the key factors for coating a good appearance film. The three roller machine is mainly used in occasions with high surface requirements.
保温铝卷涂装后处理阶段后处理段是用来对生产出的卷铝做进一步的加工,赋予它更好的防护和装饰效果。主要有贴膜、印花、压花和压型。在这简单的说明一下:贴膜是将聚稀烃可剥落性膜压贴在面漆上,印花是在涂完面漆的金属卷上在上面印上各种花纹及图案。压花是在漆膜表面上热压出浮雕似的图案。压型就是通过阴阳纹相匹配的钢辊,被压出立体的图案。
The post-treatment section in the post-treatment stage of thermal insulation aluminum coil coating is used to further process the produced aluminum coil and give it better protection and decoration effect. There are mainly film, printing, embossing and molding. Here's a simple explanation: film pasting is to press and paste the peelable polydilute hydrocarbon film on the top coat, and printing is to print various patterns and patterns on the metal roll coated with the top coat. Embossing is the hot embossed pattern on the surface of the paint film. Pressing is to press out a three-dimensional pattern through a steel roller with matching Yin and Yang patterns.
