在铸造、锻造、汽车零部件等行业，金属工件表面常残留氧化皮、锈蚀、铸造砂等杂质，若不及时清理，会影响后续加工精度与产品寿命。自动式抛丸机正是解决这一问题的“神器”——它通过高速旋转的叶轮将钢丸以“弹雨”之势喷射到工件表面，让金属工件“焕然一新”。

In industries such as casting, forging, and automotive parts, impurities such as oxide scale, rust, and casting sand often remain on the surface of metal workpieces. If not cleaned in a timely manner, it will affect the subsequent processing accuracy and product life. The automatic shot blasting machine is the "miracle tool" to solve this problem - it sprays steel shot onto the surface of the workpiece in a "rain of bullets" through a high-speed rotating impeller, making the metal workpiece "refreshed".

自动式抛丸机的核心工作原理是“动能转化+机械冲击”。叶轮在电机驱动下高速旋转（转速可达2000-3000r/min），将磨料加速至80-100m/s的速度，以扇形轨迹喷射到工件表面。高速抛出的弹丸形成扇形束，均匀地打击在工件表面上，通过机械冲击力去除氧化皮、锈蚀，从而达到清理的目的。自动式抛丸机主要由抛丸系统、输送系统、分离与回收系统三大系统协同工作。采用双叶轮或多叶轮设计的设备可实现360°无死角清理。

The core working principle of an automatic shot blasting machine is "kinetic energy conversion+mechanical impact". The impeller rotates at high speed (up to 2000-3000r/min) driven by the motor, accelerating the abrasive to a speed of 80-100m/s and spraying it onto the surface of the workpiece in a fan-shaped trajectory. The high-speed projectile forms a fan-shaped beam and hits the surface of the workpiece evenly, removing oxide and rust through mechanical impact force, thus achieving the purpose of cleaning. The automatic shot blasting machine is mainly composed of three major systems that work together: shot blasting system, conveying system, and separation and recovery system. Equipment designed with double or multiple impellers can achieve 360 ° cleaning without dead corners.

自动式抛丸机按输送方式可分为多种类型。履带式抛丸机通过履带连续输送小型工件（如汽车螺栓、螺母），适用于中小型批量工件。QPL150自动上卸料履带抛丸机实现了整个抛丸过程的完全自动化：料斗自动送料、大门自动关闭、抛丸器自动开启、清理完毕后大门自动开启、履带自动卸料。轨道台车式抛丸机适合大型工件（如发动机缸体、机床床身），可通过程序控制台车行进速度。辊道式抛丸机则擅长处理板材、型材、结构件等长尺寸工件，可实现连续通过式作业。

Automatic shot blasting machines can be divided into various types according to their conveying methods. The track type shot blasting machine continuously transports small workpieces (such as car bolts and nuts) through tracks, suitable for small and medium-sized batch workpieces. The QPL150 automatic loading and unloading track shot blasting machine achieves complete automation of the entire shot blasting process: automatic feeding of the hopper, automatic closing of the gate, automatic opening of the shot blasting machine, automatic opening of the gate after cleaning, and automatic unloading of the track. The track car type shot blasting machine is suitable for large workpieces such as engine cylinder blocks and machine tool beds, and can control the speed of the car through a program console. Roller shot blasting machines are adept at processing workpieces of equal length, such as plates, profiles, and structural components, and can achieve continuous pass through operations.

自动式抛丸机的关键优势集中在“出色、均匀、环保”三大维度。效率方面，履带式抛丸机每小时可清理800-1200件小型金属工件，替代5-8名人工。均匀性方面，通过准确控制叶轮转速、磨料类型与喷射角度，工件表面粗糙度差异可控制在Ra1.6μm以内。环保方面，抛丸机配备密封式抛丸室与除尘系统，可将粉尘浓度控制在10mg/m?以下。磨料回收率可达95%以上，大幅降低耗材成本。从汽车零部件到轨道交通装备，从火力发电设备到航天部件，自动式抛丸机已成为金属表面自动化清理的“关键利器”。

The key advantages of automatic shot blasting machines are concentrated in the three dimensions of "efficiency, uniformity, and environmental protection". In terms of efficiency, the tracked shot blasting machine can clean 800-1200 small metal workpieces per hour, replacing 5-8 manual labor. In terms of uniformity, by accurately controlling the impeller speed, abrasive type, and spray angle, the surface roughness difference of the workpiece can be controlled within Ra1.6 μ m. In terms of environmental protection, the shot blasting machine is equipped with a sealed shot blasting chamber and dust removal system, which can control the dust concentration at 10mg/m? following. The abrasive recovery rate can reach over 95%, significantly reducing the cost of consumables. From automotive components to rail transit equipment, from thermal power generation equipment to aerospace components, automatic shot blasting machines have become a key tool for automated cleaning of metal surfaces.
