Product Description
Application and operating principle

Aluminum can internal lacquering machine is the necessary equipment for automatic aluminum can production line. To meet the requirements of aluminum cans and effectively separate contents inside and aluminum can,it is necessary to spray a stable chemical protective layer on the inner wall of the aluminum can. Usually,the coating material is epoxy resin. Thus the machine is called internal lacquering machine.

Cans are pushed into sprayer cups plate by push rod. Ferguson indexer drives the turntable and makes the cups plate come to the lacquering station. There are 6 spray guns fixed on the roller and the guns move back and forward along with the roller and swing from left to right with the can chain to finish one working cycle. Once spray guns finish a cycle, the chain passes by two cups plate, which means each spray gun sprays once every other a can. Thus each can is sprayed 3times. In addition, each spray gun can be controlled separately and set to run different programs according to client’s needs.

After the procedure, cans are sent to curing oven.

Main features

  • SIEMENS PLC ensures the precise control of each action. Ferguson indexer increases indexing accuracy. Text display is in both Chinese and English. Pressure of each spraying station can be precisely controlled by independent gas-pressure meter.
  • Reciprocating motion of the machine employs crank structure and the machine runs smoothly. The inlet and outlet of cans adopt modified structures, to ensure steady conveying process and easy detachment.
  • The main motor is made in Taiwan, and the frequency converteris reliable and convenient for controlling frequency and speed. The spray gun is a new type of spray gun which is invented by our company and guaranteed excellent in function.
  • The good self-inspection system can ensure that each can should be sprayed. If the can does not work well, the machine would stop working automatically. Text display can show instant information like production speed, spray gun running pulse data,etc.
  • Each spray gun’s operating program can be set and controlled separately to realize the best spraying effect.
  • The design of chain cup plate tracking spraying movement can save a lot of time.
