How to "extend life" of automatic flat die-cutting machine

With the improvement of the quality of paper printing and packaging products, automatic flat-bed die-cutting machines have been more and more widely used in the paper packaging and printing industry. However, due to the lack of maintenance knowledge of the operators, many machine failures occurred, which directly affected the normal operation of production, resulting in higher production costs, disrupting the production schedule, and having a great impact on the delivery date.

　　 First of all, the operator should pay attention to dust and clean. In actual production, a large amount of waste paper edges and paper lint will be generated when die-cutting the carton. If you don’t pay attention, it will enter the chain transmission part, die-cutting part moving platform and some rotating parts, and may block the photoelectric detection head, etc. , Causing malfunction. Therefore, the cleaning of the die-cutting machine's body must be the first priority, and then the trouble-free operation of the machine can be ensured.

　　 Next, change the oil of the die-cutting machine. The main action of the die-cutting machine is that the main motor drives the slide bars and pulleys, and then drives the four toggle bars to move. It can reach 6000 sheets per hour in high-speed work. It is very troublesome if there is no good lubrication and cooling. Lubrication maintenance is divided into daily warranty, weekly warranty and monthly warranty, as shown in the following table:

　　 Maintaining the machine is what every operator must do. Because the machine is not well maintained, it increases maintenance costs and business expenses; secondly, it causes great damage to the machine and shortens the service life of the machine; the three affect operation and delay production. Machine failure will definitely affect the operator's mood and delivery deadlines.

After 　　, the common faults of the die-cutting machine should be eliminated in time. In terms of machinery, the common failure of the automatic flat die cutting machine is the phenomenon of platform slanting. In this case, most of the foreign matter falls into the die-cutting position. Generally, the two wedge-shaped positions under the drag shaft should be adopted, and at the same time, the platform should be rotated to the upper limit point. At this time, detect its relative position to the upper net platform to ensure the distance between the four angles of the movable platform and the upper net platform (where the die-cutting board is clamped), so that the problem can be solved. Electrical faults include: Because the central control system of the automatic die-cutting machine uses a programmable logic controller (PLC), the main detection point electrical switches and output actions are all started from this, and the internal program of the PLC is a ladder logic diagram. Therefore, when there is a problem in the electrical field, the maintenance personnel must first read the ladder logic diagram to judge and find the cause of the failure, so that the problem will be solved quickly. Regardless of whether it is a fully automatic or semi-automatic flat die-cutting machine, professionals need to be refueled and maintained. It is necessary to understand the structure and performance of the machine in order to maintain a machine.
