The transmission system adopts large spiral angle helical gear transmission, low noise, enhance the strength of gear, improve the transmission stability of gear.All transmission gear adopt 40CrMnTi alloy steel,processed with grinding,hardening.With closed spray lubrication device,lubrication oil level is kept consistent and ensure the transmission accuracy of the machine in long term running. Each unit is electrical separated and equipped with alarm bell,and the alarm is continuously warning while machine separating or uniting to ensure operator's safety.Clutch motor with constant torque clutch,cushioning misoperation when each unit collides with each other. Each unit is pneumatic locked when closed and equipped with total locking device,which can integrated each unit with the bottom rail locking.Main motor cannot start and run when cylinder is not locked,while locked cylinder cannot open when main motor is running.After the separation of each unit,the transmission system is automatically brake and keep the gear in its original position. Each unit has automatically zeroing system,which can be adjusted to the correct size by testing a small amount of paperboard to reduce the waste of cardboard. The whole machine has beautiful looking and soft color.Modular design allows to add or subtract units at will. This machine lead edge feeding,printing,slotting,die cutting units spare parts processing technology. ------------ Side wallboard casting--artificial ageing treatment--force plane--adjustable cast iron planes--Integral precision machining of large machining center--quality inspection--in stock :-------------------- Gear:Forge--rough turn--hardening and tempering--finish turning--hobbing--heat treatment--fine grinding inner hole and surface--High precision gear grinder gear grinding processing--special gear tester test--quality inspection--in stock :()------------------------.
