Maintenance of carton die cutting machine

With the improvement of the quality of paper printing and packaging products, the automatic flat-bed die cutting machine has been more and more widely used in the paper packaging and printing industry. However, due to the lack of maintenance knowledge of operators, the machine has more failures, which directly affects the normal operation of production and increases production costs. Not only disrupted the production arrangement plan, but also had a great impact on the delivery time. In order to further improve the operation technology of the automatic flat-bed die-cutting machine, carry forward the new technology of the die-cut machine, and improve the modern operation level, we now summarize some maintenance points and knowledge of the automatic flat-bed die cutting machine for peer Exchange and sharing.

First, operators should pay attention to dust and clean. In actual production, a large amount of waste paper edges and paper wool will be generated when die-cutting the carton. If it is not careful, it will enter the chain transmission part, the die-cutting part moving platform and some rotary motion parts, and may block the photoelectric detection head, etc , Causing malfunctions. Therefore, the cleaning of the body of the die-cutting machine must be placed first, and then the machine can be operated without problems.

Second, the oil change of the die-cutting machine. The main action of the die-cutting machine is that the main motor drives the slide bar and the pulley, and then drives the four pairs of elbow bars to move. It can reach 6000 sheets per hour in high-speed work. Without good lubrication and cooling, it is very troublesome. Lubrication and maintenance are divided into daily warranty, weekly warranty and monthly warranty, as follows:

Daily lubrication

1. Lubricate the side gauges, gears, cam stroke bearings, pressure rod movements, feeder head cams and direction joints.

2. The main chain is lubricated, and the automatic lubrication device maintains the oil level and oil number.

Weekly lubrication

1. Add oil and butter to the front regulation device.

2. Add oil to the front gauge and cam, add chain oil to the test gauge drive chain, and add grease to the spring.

3. Add oil to the lifting cam of the Feida part, add butter to the spring.

4. Add chain oil to the drive chain of Feida Department.

5. SS type waste opening and closing mechanism is lubricated with oil.

6. Add oil to the upper template tightening device.

7. SS type cleaning and reciprocating movement parts: A: spring plus butter, B: axle joint plus engine oil

8. Add oil to the dental row.

9. Add butter to the paper feed cam unit.

10. Add oil to the paper alignment section before the paper collection section.

11. Add oil to the left and right paper aligning devices in the take-up section.

12. Add oil to the pressure regulating chain.

13. Wipe the body at least twice a week to remove dust.

Monthly lubrication

1. Grease the clutch.

2. Add oil to the cam device of the second home block; add butter to the spring.

3. Add grease to the sprocket tensioner in the take-up section.

4. Add SS to the guide shaft of SS type cleaning and reciprocating moving parts.

5. SS type waste opening and closing mechanism is lubricated and greased.

other

1. The main transmission room is lubricated and the engine oil can be changed at most once every six months, depending on the clarity of the window oil.

2. Lubrication of angle splitter, once every six months.

3. Lubricate the air compressor and add it once every three months.

Maintaining the machine is something every operator must do. Because the maintenance of the machine is not good, firstly, it will increase the maintenance cost and increase the company's expenditure; secondly, it will cause great damage to the machine, resulting in a shortened service life of the machine; Machine failure will definitely affect the operator's mood and delivery deadline.

Finally, the common faults of the die-cutting machine should be eliminated in time. Mechanically, the common failure of the automatic flat-bed die-cutting machine is the platform slant phenomenon. In this case, most of the foreign objects fall into the die-cutting place. Generally, you should take the position of dragging the two deed blocks under the shaft, and at the same time, rotate the platform to the upper limit point. At this time, detect the relative position with the upper net platform to ensure the distance between the four angles of the moving platform and the upper net platform (where the die cutting board is placed). This will solve the problem. The electrical faults are: Because the central control system of the automatic die-cutting machine uses a programmable logic controller (PLC), the main detection point electrical switch and output action are all based on this, and the PLC's internal program is a ladder logic diagram.
