    Daily maintenance and maintenance of fully automatic die cutting machine
    From:Zhoushan Putuo Light Industry Machinery Factory  Date:2018/7/18 14:53:49  Onclick:194

    With the improvement of the quality of paper printing and packaging products, the fully automatic flat die cutting machine has been widely used in the paper packaging and printing industry. However, due to the lack of maintenance knowledge of the operators, the machine has more faults, which directly affects the normal operation of the production, resulting in higher production costs, which disrupts the production scheduling plan and has a great impact on the delivery date. In order to further improve the operation process of the automatic flat die cutting machine, carry forward the new technology of the die cutting machine and improve the modern operation level, the author summarizes the automatic flat die cutting machine according to the work experience in this field in these years. Some maintenance points and maintenance knowledge are shared with colleagues.

    First of all, the operator should pay attention to dust and clean. In actual production, a large amount of waste paper edge and paper hair will be produced when die-cutting the carton. If you pay attention, you will enter the chain transmission part, the die-cutting part moving platform and some rotating motion parts, and may block the photoelectric detection head, etc. , causing a malfunction. Therefore, it is necessary to put the cleaning work of the die-cutting machine in the first place, and then ensure that the machine runs without trouble.

    Second, the oil change of the die-cutting machine. The main action of the die-cutting machine is that the main motor drives the sliding rod and the pulley, and then drives the four pairs of toggles to move. It reaches 7000 sheets/hour in high-speed work. It is very troublesome without good lubrication and cooling. Lubrication maintenance is divided into daily insurance, weekly insurance and monthly insurance, etc., as shown in the following table:

    Maintaining the machine is something that every operator must do. Because the machine is not well maintained, it will increase the maintenance cost and enterprise expenses; secondly, it will cause great damage to the machine, resulting in shortened service life of the machine; the three will affect the operation and delay production. Machine failures will definitely affect the operator's mood and delivery deadlines.

    Finally, it is necessary to eliminate the common faults of the die-cutting machine in time. In terms of machinery, the common faults of the fully automatic flat die cutting machine are the platform press-slope phenomenon. In this case, the foreign matter falls into the die-cutting place. Generally, the position of the two wedges under the shaft should be taken, and at the same time, the platform is rotated to the upper limit point. At this time, the relative position of the upper platform is checked to ensure the distance between the four angles of the moving platform and the upper net platform (where the die cutting board is placed), so that the problem can be solved.

    The electrical faults are: Because the central control system of the automatic die-cutting machine adopts the programmable logic controller (PLC), the electrical switch and the output action of the main detection point are all started, and the internal program of the PLC is the ladder logic diagram. Therefore, when there is a problem in electrical, the maintenance personnel must first read the ladder logic diagram to judge and find the cause of the fault, so that the problem will be solved quickly. Whether it is a fully automatic or semi-automatic flat die cutting machine, professionals are required to refuel and maintain. It is necessary to understand the structure and performance of the machine so that one machine can be maintained.
