Problems solved by technology
[0002] In the medium and high density fiberboard production line, before the slab enters the continuous hot press, there is a discarded board outlet for pumping out waste fibers, and a high-power fan equipment is required at the outlet to pump the waste fibers to the material storage In consideration of integrated management and safety factors, most of the existing production lines use bus control for the fan equipment at the discharge port and the fans in other links, that is, to start and close at the same time, but the fan at the discarded board discharge port The effective working time is different from that of fans and other equipment in other links, resulting in the idling of the fan at the discarded board outlet and wasting energy consumption, or requiring complex operations from the control terminal of the production line to individually close and open the discarded board outlet. fan; therefore, the prior art lacks a method that can both integrate and control the fan at the outlet of the discarded plate at the same time

The invention discloses an abandoned plate discharging opening fan control system which comprises a PLC. The PLC comprises a first output positive electrode and a first output negative electrode. A first control loop is connected between the first output positive electrode and the first output negative electrode. The first control loop comprises a relay KA1, a knob switch SQ1, a moving-combining switch SB1 and a moving-disconnecting switch SB2. A coil first end of the relay KA1 is connected with the first output negative electrode. A coil second end of the relay KA1 is connected with a first contact of a first end of the knob switch SQ1. The moving-combining switch SB1 and the moving-disconnecting switch SB2 are connected in series. The moving-combining switch SB1 and a first pair of contacts in a main contact head of the relay KA1 are connected in parallel. Accordingly, a self-locking switch is formed.
Description
technical field [0001] The invention relates to the field of electrical control, in particular to a fan control system for a discarded board discharge port.
