Scraper Chain for Grain Machines (Welded Steel Chain)
The welded steel chain is also called scraper chain, and is widely used throughout the grain processing industry. It is compatible with abrasive materials, and mainly supports low speed load carrying. Additionally, it is able to work in severe environments with heavy dust and strong impacts.
This type of conveyor chain is composed of bended sidebars which are exactly the same. The sidebars are connected with each other directly without other types of link plates. The chain link can be either odd or even number. The sleeve and sidebars are welded together, which ensures simple but durable structure.
In order to make scraper chains with improved quality and extended service life, we adopt automatic welding robots to weld the bushing and sidebar together. The precision equipment guarantees uniform and stable welding quality. Meanwhile, we conduct inspections according to the Quality Control Standard of international leading roller chain manufacturers. Additionally, according to the proportion of 5%, our welded steel chain products undergo conduct destructive tests to ensure approved welding quality. Our patented high frequency induction heating treatment for the pins offers higher strength while improving the wearing resistance.

Other Material Handling Equipment:
Akodi supplies Tool Trolley For Workshop. Also, we have mobile dock ramp and Container Loading Ramp for transporting goods on and off trailers. Stationary dock ramp is also popular for warehouse dock application. Furthermore, for narrow aisle, we supply aluminum alloy lifting platform to assist the aerial cleaning or aerial maintenance job to be done more efficiently.
Automatic cleaning machine for welding gun: save time, improve efficiency, stable welding quality
In general, we are accustomed to the use of hand loosened gun mouth cleaning, finished and then screwed back. However, this approach is not safe, waste of time, and may be due to the tightness of welding will directly affect the efficiency of finished product quality.
For these reasons, Akodi developed an automatic cleaning machine for welding gun. After programming, the machine will automatically clean the gun. The process will only take less than one minute to achieve a thorough cleaning effect. However it will take up to 10 minutes for the traditional method. It will not only clean the gun nozzle by injecting oil but also cut wires.
