- The transmission gear system adopts automatic circulating lubrication to maintain smooth operation.
Printing Unit
- The printing roller is manufactured from seamless steel tube with surface polishing and hard chrome plating.
- The printing cylinder and transmission system are dynamically balanced to maintain stable operation.
- The transmission shaft and gear connection adopt keyless locking structure to maintain printing accuracy.
- The gap adjustment of the paper feeding roller, embossing roller, anilox roller and rubber roller adopts self-locking adjustment structure.
- The printing phase adopts planetary gear adjustment with electric digital 360° adjustment, which can be adjusted during machine operation or stop.
- The printing plate cylinder supports quick phase adjustment.
- The pneumatic brake system maintains the original gear position during unit separation or adjustment.
- The anilox roller adopts hard chrome plating with optional mesh selection according to printing requirements.
- The ink circulation system uses a pneumatic diaphragm pump to provide stable ink supply.
- The printing registration accuracy can reach ±0.5 mm according to operating conditions.
Slotting Unit
- The slotting unit supports adjustment according to different corrugated board thicknesses including 3 ply, 5 ply and 7 ply board.
- The rear slotting knives can be adjusted synchronously for convenient operation.
- The main gear adopts keyless connection to maintain long-term slotting accuracy.
- The slotting knives use ground tooth profiles with sharp cutting edges.
- Slotting accuracy can reach ±1 mm according to operating conditions.

FAQ
What is the difference between a flexo printer slotter and a flexo printer slotter die cutter?
A flexo printer slotter mainly performs flexographic printing and slotting operations, while a flexo printer slotter die cutter additionally includes a die cutting unit for cutting special carton shapes.
Why is chain feeding used in a semi automatic flexo printer slotter?
Chain feeding provides stable cardboard transportation and positioning, which helps maintain consistent printing and slotting accuracy during production.
What tpes of corrugated board can be processed by this machine?
The machine is suitable for processing 3 ply, 5 ply and 7 ply corrugated cardboard sheets according to machine configuration.
Is a semi automatic flexo printer slotter suitable for small carton factories?
Yes. This type of machine is commonly used by small and medium carton manufacturers that require printing and slotting functions with flexible production requirements.
How accurate is the printing registration of this machine?
The printing registration accuracy can reach approximately ±0.5 mm under suitable operating conditions and proper machine adjustment.
What factors should be considered when choosing a flexo printer slotter?
Customers should consider working width, printing colors, feeding method, production volume, carton size range and required functions such as die cutting or folding.
Can this machine produce different carton sizes?
