Application and operating principle
To meet the requirements of aluminum tube and effectively separate contents inside and aluminum it is necessary to spray a stable chemical protective layer on the inner wall of the aluminum tube. Usually，the coating material is epoxy resin. Thus the machine is called internal lacquering machine.
Germ tubes from annealing oven fed into the tube slot and then are pushed into the 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 tube 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 tube. Thus each tube 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, tubes are sent to curing oven.
- 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 tubes adopt modified structures, to ensure steady conveying process and easy detachment.
- The main motor is made in Taiwan, and the frequency converter is 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 tube should be sprayed. If the tube 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.
