涂布機主要用于薄膜、紙張等的表面涂布工藝。這種機器是在卷好的基材上涂上一層具有特定功能的膠水、涂料或油墨，然后晾干，卷起來。

The coating machine is mainly used for surface coating processes of thin films, paper, etc. This type of machine is to apply a layer of adhesive, coating or ink with specific functions on a rolled substrate, then air dry and roll it up.

　　對于涂布機來說，常見的故障主要3種：

For coating machines, there are three common malfunctions:

　　1、涂布機傳動部件磨損，如涂布機干燥機軸頭磨損、卷繞輥軸承室磨損等。傳統的修復方法包括堆焊、熱噴涂、電刷鍍等，但都有一定的缺點，如堆焊會使零件外觀達到很高的溫度，形成變形或裂紋，嚴重時會導致軸開裂。

1. The transmission components of the coating machine are worn, such as the shaft head of the coating machine dryer and the bearing chamber of the winding roller. Traditional repair methods include welding, thermal spraying, brush plating, etc., but they all have certain drawbacks. For example, welding can cause the appearance of parts to reach high temperatures, forming deformation or cracks, and in severe cases, it can lead to shaft cracking.

　　2、正極重量分布不均。涂布機使用時間長了會出現正極重量分布不均，出現薄的現象中間和薄邊，影響生產進度。影響涂層均勻性的因素很多，包括材料、漿料粘度、漿料均勻度、基板厚度均勻度；設備、刮刀與涂布輥徑向圓度、軸向平整度、刮刀與涂布輥安裝平行度等。

2. The weight distribution of the positive electrode is uneven. Over time, the coating machine may experience uneven weight distribution of the positive electrode, resulting in thin edges and edges, which can affect production progress. There are many factors that affect the uniformity of coatings, including materials, slurry viscosity, slurry uniformity, and substrate thickness uniformity; Equipment, scraper and coating roller radial roundness, axial flatness, scraper and coating roller installation parallelism, etc.

　　3、涂布機混凝土基礎損壞。布機由于腐蝕、老化等因素的影響，會損壞混凝土底座等部位，導致緊固設備的螺栓松動，影響生產。傳統的混凝土澆筑方式進行處理會延長修復時間，企業難以接受。高分子復合材料很好的解決了這個問題，材料本身的抗沖擊和抗壓強度遠遠大于目前的混凝土材料。

3. The concrete foundation of the coating machine is damaged. Due to factors such as corrosion and aging, the fabric machine can damage the concrete base and other parts, resulting in loose bolts for fastening equipment and affecting production. The traditional method of pouring concrete for treatment will prolong the repair time, which is difficult for enterprises to accept. Polymer composite materials have effectively solved this problem, as their impact resistance and compressive strength are far greater than those of current concrete materials.
