1. A floor decoration tile manufacturing system comprising:
a raw material supply unit configured to store a raw material for forming a lower sheet and a middle sheet;
a lower sheet supply unit configured to form and supply the lower sheet;
a middle sheet supply unit configured to supply the middle sheet bonded onto the lower sheet;
a main roller configured to bond the lower sheet and the middle sheet, which have been supplied;
a first sheet supply unit configured to supply a print sheet having a color or a pattern to the main roller;
a second sheet supply unit configured to supply a transparent sheet, which is bonded onto the print sheet, to the main roller; and
a control unit configured to control a tile manufacturing process through pressing the main roller by controlling driving speeds of the raw material supply unit, the lower sheet supply unit, and the middle sheet supply unit and rotation of the main roller such that the print sheet and the transparent sheet, to which the lower sheet and the middle sheet are bonded, are sequentially pressed,
wherein the control unit controls heating temperatures for the raw material, the lower sheet, the middle sheet, and tile manufacturing sections,
wherein the lower sheet supply unit and the middle sheet supply unit generate the lower sheet and the middle sheet by simultaneously compressing raw sheets received from the raw material supply unit while allowing the raw sheets to pass between two heating rollers and supply the lower sheet and the middle sheet, which have been generated, to the main roller by feeding the lower sheet and the middle sheet to a meander structure by a wire conveyor connected to a plurality of rollers provided on an upper or lower side thereof, and
wherein a laser sensor configured to measure a distance between a bottom surface, which faces the lower sheet and the middle sheet fed to the meander structure, by irradiating an infrared ray toward the lower sheet, and the middle sheet is provided on the bottom surface.
