送纸：链条推纸进料。
这是纸箱行业发展变化的另一个落脚点，代表纸箱包装的发展方向，将使纸箱生产进入专业化分工合作的新时期。
　　瓦楞纸板后加工设备是纸箱生产的重要组成部分。在经济发达地区，中小企业都在改造和加强后加工设备，把原来加工纸板的小设备去掉，按市场业务量重新配置和强化后加工设备，从根本上打破“大而全”、“小而全”的落后模式，使纸箱质量全面提高。只有这样，才能适应我国加入WTO后的市场需要。
　　由于我国产品包装长期以来只强调外销包装的质量。今后，我国同国际接轨，在经济全球化时代，内外销产品包装的质量将日趋一致。在发展后加工设备的技术、工艺、档次等方面应该引起行业的重视。例如苏州吴中三元纸盒厂是一家典型的村办小而全企业，原来加工纸箱有单面机、单机，后加工、印刷、开槽、钉箱等机器，也都是国产设备，一年产值三五百万元。老板动脑筋，把国产小设备统统处理掉，从台湾购进一台小型印刷开槽机，一台自动钉箱机，使用高档线加工的纸板，通过后加工的纸箱，质量不亚于用高档生产线生产的产品。产品质量上了档次，企业很快发展起来，产值扩大到2000多万元。这是对后加工设备投资改造的成功典型。
本纸箱机械机组开合采用电动行走(有过载保护功能)气动锁紧；
送纸辊：上轴采用压花送纸轮，下轴采用钢质压花辊，表面镀硬铬、保证纸板的顺利送入和不破坏瓦楞面纸。
印刷辊：可采用先进简便实用的勾槽挂版(可选)。装卸版时可由脚踏开关独立控制。相位调整采用不停机360度电动数字式调整，可根据误差输入数据，自动调整。
Performance of the main mechanisms:
Paper-feeding:Chain,paper pushing feeding.
Open and closing lf the unit adopts electrical walking and pneumatic locking (with overload protection function).
Paper-feeding roller:The upper axie adopts ginning paper-feeding wheel while the lower axle adopts steel ginning roller.The surface hard chromium-plating guarantees the smooth feeding of the paperboard and does not damage the corruagted cap.
Printing roller,You can adopt the advanced,convenient and practical hanging plate with hooked slots(Optional).Loading and unloading the plate can be independently controlled by the pedal switch.The phase adjusting adopts non-stop-working,360″electrical and numerical adjustment.input the data as per the error.Automaticallyadjust.
Ink circulating system
①The anilox roller adopts the steel material 220 wire or the 220 wire combined anilox roller.
②The rubber roll3er is made up of matural oil proof,acid proof and alkali proot rubber.
③Pneumatic diaphragm pump inking,automatic circulating,Automatic cleaning after adding water.
④Stop working to distribute ink.Stop working and the work lf the ink circulating system for a short time.Cleaning-free to guarantee the quality of the printed things and make the inking color showing no differdnce.
⑤Pneumatic comtrol lf the anilox and rubber rollers of the ink circulating system.Quick lifting can print more tiny script,fine pattern or color process,It can make the printed matters clear,full and round.
Slotting part(Optional)
①The slotting part can electrically adjust the phase in 360°
②Hand adjust the height of the carton,Four knives are synchronous
③Long and wide adjusting.Loading and unloading the knife disk.Upper and lower creasing.Paper-kicking knife.Creasing shaft.The pointer of the scale can be hand and combinedly moved to save time.(SYK4260,SYK4860 have this function)
Pneumatic and combined control of the whole machine which has the function of counting,alarming and operating at the back of the machine.
