自動式拋丸機（Automatic Shot Blasting Machine）是一種用于表面處理的機械設備，它主要通過噴射高速金屬顆粒或磨料來清理、腐蝕和強化工件表面。其工作原理包括以下幾個關鍵步驟：

　　An automatic shot blasting machine is a mechanical equipment used for surface treatment, which mainly cleans, corrodes, and strengthens the surface of workpieces by spraying high-speed metal particles or abrasives. Its working principle includes the following key steps:　　工件進料：工件被放置在拋丸機的工作室中，可以手動放置或通過輸送系統進行自動輸送。

　　Workpiece feeding: The workpiece is placed in the studio of the shot blasting machine and can be manually placed or automatically conveyed through the conveying system.

　　準備工作：在開始拋丸之前，需要對工件進行一些準備工作，如清潔表面，遮蓋不需要處理的部分等。

　　Preparation work: Before starting shot blasting, some preparation work needs to be done on the workpiece, such as cleaning the surface, covering the parts that do not need to be treated, etc.

　　拋丸噴射：拋丸機內部有一個拋丸噴射系統，通過電動機驅動噴丸輪高速旋轉。在噴丸輪上安裝有刀片，噴丸材料（例如鑄鋼彈丸、鋼砂等）被刀片甩離，形成高速運動的彈丸流。

　　Shot blasting: The shot blasting machine has an internal shot blasting system that drives the shot blasting wheel to rotate at high speed through an electric motor. A blade is installed on the shot peening wheel, and the shot peening material (such as cast steel pellets, steel sand, etc.) is thrown away by the blade, forming a high-speed projectile flow.

　　彈丸沖擊：高速運動的彈丸流被通過噴嘴噴射到工件表面上，彈丸與工件表面碰撞產生沖擊力，將表面的污垢、氧化層、油漆等物質剝離或清除。

　　Bullet impact: The high-speed projectile flow is sprayed onto the surface of the workpiece through a nozzle, and the projectile collides with the workpiece surface to generate an impact force, stripping or removing surface dirt, oxide layer, paint and other substances.

　　彈丸收集和循環：拋丸機會在機器底部設置一個彈丸收集系統，將使用過的彈丸通過輸送裝置收集起來，然后通過清潔分級設備進行篩選和清潔，并再次送回噴丸系統進行循環使用。

　　Bullet collection and circulation: The shot blasting machine sets up a bullet collection system at the bottom of the machine, collects used bullets through a conveying device, and then screens and cleans them through cleaning and grading equipment, and sends them back to the shot blasting system for recycling.

　　除塵處理：為了避免產生大量粉塵污染環境，拋丸機通常還會配備除塵設備，通過吸塵系統將產生的粉塵和廢氣進行處理和凈化。

　　Dust removal treatment: In order to avoid generating a large amount of dust pollution to the environment, shot blasting machines are usually equipped with dust removal equipment, which processes and purifies the generated dust and exhaust gas through a vacuum system.

　　通過以上工作步驟，自動式拋丸機可以高效地清理和處理工件表面，達到提高工件質量、增加附著力和延長工件使用壽命的目的。

　　Through the above work steps, the automatic shot blasting machine can efficiently clean and treat the surface of the workpiece, achieving the goal of improving the quality of the workpiece, increasing adhesion, and extending the service life of the workpiece.
