Embodiment 1

[0030] This embodiment discloses a power supply misplacement circuit for a corrugated cardboard printing machine.

[0031] refer to figure 1 , figure 1 The dotted line in the middle indicates linkage, for example: the dotted line of SA1 indicates that the key selector switch has two normally open contacts, which act at the same time; another example: SB2 and HL1 are connected together by a dotted line, which means that the main power indicator HL1 is connected with the main power indicator. The power start button SB2 is assembled together, called the button with light, one starts, one indicates, and the indicator light will be on after pressing the start. like figure 1 As shown, the circuit structure of this embodiment is as follows:

[0032] The nodes 1, 3, 5, 7, 9, 11, and 13 distributed between the L terminal and the N terminal are the connection points between the two circuit components; the circuit components include: the power start-stop key selection switch SA1, whic...

Abstract

The invention relates to the technical field of industrial control of a printing machine, and discloses a power supply mis-placing circuit of a corrugated board printing machine. By the power supply mis-placing circuit, sequent starting and stopping of various types of power supplies is solved, and energization and outage due to accidental operation are prevented. A circuit between an L end and anN end is divided into a ring branch, a general power supply indication branch, a general power supply starting branch, a servo power supply indication branch and a servo power supply starting branch,a constituent component comprises a power supply starting-stopping key selection switch, a general power supply AC contactor, a general power supply starting button, a servo power supply AC contactor, a servo power supply stop button, a servo power supply starting button, a ring alarm, a general power supply indication lamp and a servo power supply indication lamp, the power supply starting-stopping key selection switch is provided with two normally-open contacts in linkage, the general power supply AC contactor is provided with three normally-open contacts in linkage and a coil, the generalpower supply starting button is provided with two normally-open contacts in linkage, the servo power supply AC contactor is provided with two normally-open contacts in linkage and a coil, and thus, the circuit between the L end and the N end is divided into seven nodes.

Description

technical field [0001] The invention relates to the technical field of printing machine industrial control, in particular to a power supply misplacement circuit for a corrugated cardboard printing machine. Background technique [0002] With the development of corrugated cardboard printing machines, high-definition printing machines with servo shaftless transmission instead of gear transmission have become an industry development trend. [0003] The electrical control of the full-servo shaftless drive corrugated cardboard high-definition printing machine is quite complicated, including power supply, control power supply, servo power supply and other types of power supplies. For the safety of the equipment and the needs of the control system, various power supplies need to be started in a certain order or stop. [0004] In the actual production process, it is necessary to prevent power outages and shutdowns caused by human misoperations from affecting production and damaging ...
