Embodiment Construction

[0041] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] A PLC control system for plastic floor vulcanizing machine, including fuse, PLC, touch screen, pressure sensor, A / D conversion module, control relay, AC contactor, thermal overload relay, temperature controller, transistor driver board and switch power supply,

[0043] The fuse is used for short-circuit protection of the control system. All devices that use single-phase power supply are powered through the fuse (mainly PLC, thermostat, switching power supply), and the power is taken from phase A.

[0044] Touch screen, connected to PCL through RS485 communication, to realize parameter setting, data monitoring and PLC I / O monitoring;

[0045] PLC is the hear...

Abstract

The invention discloses a PLC (Programmable Logic Controller) control system of a plastic floor vulcanizing machine and a control method thereof. The PLC control system of the plastic floor vulcanizing machine comprises a fuser, a touch screen, a PLC, a pressure sensor, an A / D (Analogue to Digital) conversion module, a control relay, an alternating current contactor, a thermal overload relay, a temperature controller, a transistor drive panel and a switch power supply. Original relay control is replaced by the PLC, the control method is disclosed, and the purposes of stabilizing the control system and preventing the contactor from being subjected to fusion welding are realized.

Description

technical field [0001] The invention relates to the field of plastic floor production equipment, in particular to a PLC control system for a plastic floor vulcanizing machine and a control method thereof. Background technique [0002] At present, the main production process of the existing plastic floor is to crush the plastic block into fine powder → mix the plastic powder and stone powder in a certain proportion and stir evenly → put the mixed powder on the mold for the first pressing → press into a block The plastic block is unloaded and cooled (the size depends on the mold) → spread the pressed semi-finished product with the required pattern, wood grain and other pattern paper for pressing → press the semi-finished product with the pattern for the second time → unload and cool after pressing →After cleaning, ordinary paint, flame retardant paint treatment (completed by a special production line)→cut into small pieces according to the required size→chamfering, deburring t...
