II. Introduction
- This machine is composed of chain feeding system, printing, slotting, electrical system and so on. It can finish the functions of printing, pressing line, slotting, cutting in one time.
- The Wall board use HT250 with hand dealing on it, make sure it will not be curve. It is processed with boring machine, make sure the processing precision and quality of the board. The board structure is solid cast iron, with thickness 35mm, have good shockproof capacity, gears use steel straight gear with 45# steel dealt with high-frequency quenching, Precision grade is more than 6, hardness is HRC52~58. The lubrication use handle pouring. The working noise is low, the strength and driving stable is good. The gap adjust of printing and feeding use wall turbine-worm and adjust the double-stand structure, any paperboard size you want to adjust, it can make sure there is no gap driving, and make the precision high.
- All the bearings are made from Haerbin, Wafangdian and such famous brand product.
- Oil box use thick steel board dealt with finish machining, make sure there is no leak of the lubrication oil.
- Use "outside adjust the turbine-worm" for adjusting low-roller gap adjust, make sure there is no center excursion of up roller and down roller.
- Electrically separate and close of the machine, with the alarm-bell attached. During the separate and close work of the machine, the alarm-bell is ringing to make sure the safety of the workers.
- After each part closed, there are pneumatic cylinder for lock. The main power cannot open if the pneumatic cylinder does not lock. And after the main power open, the pneumatic cylinder cannot open.
- The electrical operating case of printing part and slotting part are independently, very easy to operate.
1) Paperboard Feeding Part
- Chain model feeding by hand.
- The bottom slideway of the chain use hard insulation material, can reduce the running noise.
- Cotton ginning roller avoids the skip of paperboard when feeding, this helps to improve the feeding precision. All the axis use double-plate welding, and dealt with stable-balance. After processing, dealt with refining grinding, and then coating with hard chrome.
- The main electrical motor is stepless speed-adjust, it is power-save, running stable and can run in low speed.
2) Printing Part
- The printing roll is dealt with balance check, surface grinding, coating with hard chrome and dealt with polishing.
- There are front and back transport plates in the bottom of printing plate roller, this help the paperboard-press-axis to transport the paperboard smoothly during the chromatically. This helps to make the chromatically precision very good.
- 360°electrical phase with digital display adjust equipment. Precision of distinguish is 0.5mm displayed with dial. The electrical phase adjust system use planet-gear structure, when the machine not run, it can be 360°electrical adjust. The axis direction adjust of the printing-plate-roll is by hand, can be ±20mm adjusted, this can be adjusted when machine run or stop.
- Note: The microcomputer has plate-cleaning function, there is no need pneumatic orientation during the separating and closing the machine. The microcomputer can remember the exact place of the chromatically, so no need to adjust the chromatically all the time.
- Automatically ink supply system. Pneumatic inking when pneumatic up plate, can equal ink automatically. When the machine stop, it will not effect the printing effect because of the dry of the ink. The ink return pipe is one-inch steel pipe coated with hard chrome, it can return the rest ink to the ink drum timely to avoid the ink leaking.
- Pneumatic brake system, when the machine separate, it will limit the machine working, and keep the gears' place fixed.
3) Slotting Part
- Cutting and slotting base can be 360°positive and negative electrical adjusted. Use digital display tiny-adjust equipment.
- The knives can be synchronized adjusted. The adjust is very easy, and the lock is reliable, slotting precision is good. The adjust function use inner-gear drive design and wear well.
- The back electrical control switch can control front operation. During the work, if there is urgent situation, the worker in the back can control the equipment running.
