The working mode and principle are as follows:

the first step is as follows: the working personnel adds liquid coating into the coating pool 21, turn on the blower 32, the air after pressurizing flows into the air intake manifold 28, switch on the gas delivery pipe 31, make the gas add into air intake manifold 28, the mixed air and gas after pressurizing enter the heating pipe 29, squirt from a pack of flame holes, the working personnel switch on the shutoff valve on the air supply hose 44, the gas squirts through the metal ignition pipe 45, the working personnel light the gas that the metal ignition pipe 45 squirts with the lighter, the working personnel stretch the metal ignition pipe 45 into the hollow embossing roller 19 after lighting, light the gas that a pack of flame holes squirt squirts, close the shutoff valve on the air supply hose 44 after lighting up; a group of fire-spraying holes of the heating pipeline 29 are towards the inner wall of the hollow embossing roll 19 at the gap between the second feeding pressing roll 38 and the hollow embossing roll 19 for fire-spraying heating, cooling water is continuously added to the bottom of the hollow embossing roll 19 through the water inlet pipeline 24, the hollow embossing roll 19 is prevented from being overhigh in temperature, the cooling water stored at the bottom in the hollow embossing roll 19 is continuously pumped out through the water pump 33, and the cooling water is prevented from overflowing the hollow embossing roll 19.

The outer wall of the hollow embossing roller 19 is engraved with patterns to be embossed, the hollow embossing roller 19 is driven to rotate by the first chain driving motor 41, the hollow embossing roller 19 drives the coating roller 20 to rotate when rotating, the coating roller 20 coats the liquid coating in the coating pool 21 on the outer wall of the hollow embossing roller 19, the tablecloth 100 is subjected to heating embossing on the hollow embossing roller 19,

the tablecloth 100 enters the printing station through the fourth feeding roller 37 and the second feeding press roller 38, and after printing is finished, the tablecloth 100 is sequentially fed into the next station through the first discharging roller 17 and the second discharging roller 18.

The second step is that: film coloring device begins the during operation, oil circulation electric heater 68 is started, the conduction oil constantly heats conduction oil heating roller 64, tablecloth 100 loops through tablecloth feed roller 61, coloring press roller 62 and discharge roller 63 get into next station, the staff installs the coloring cloth winding drum on coloring raw material roll installation pole 66, then install waste cloth recycling drum 102 on waste recovery pole 67, the coloring cloth 101 that coloring cloth winding drum took out passes through tensioning pole 65 and conduction oil heating roller 64 in proper order, it is retrieved with its winding by waste cloth recycling drum 102 at last, tablecloth 100 and coloring cloth 101 are together through between coloring press roller 62 and conduction oil heating roller 64, the pigment on coloring cloth 101 adheres on the decorative pattern of tablecloth 100 under the extrusion of coloring press roller 62 and the heating of conduction oil heating roller 64, accomplish the coloring to tablecloth 100.

the third step: finished tablecloth 100 output by the discharge roller 63 sequentially passes through the second tablecloth feed roller 81 and the third tablecloth feed roller 85 and is finally output between the pair of finished product discharge rollers 87, when the tablecloth 100 is conveyed, the transmission shaft 82 is driven to rotate by the motor, the transmission shaft 82 drives the first rocker 83 to rotate, the first rocker 83 drives the driving rod 84 to reciprocate back and forth, the driving rod 84 drives the second rocker 86 to swing back and forth by taking the rotating shaft of the third tablecloth feed roller 85 as the center, and as shown in fig. 2, the tablecloth 100 is folded and stacked on the supporting plate 102. When the third cloth feeding roller 85 rotates, the first roller driving chain wheel 88 is driven to rotate, the first roller driving chain wheel 88 drives the second roller driving chain wheel 89 to rotate through a chain, the second roller driving chain wheel 89 drives one finished product discharging roller 87 to rotate, and the other finished product discharging roller 87 is a pressing roller, so that the smoothness of cloth output is guaranteed. The swing range of the second swing arm 86 is increased or decreased by adjusting the driving lever connecting shaft 90 to be mounted in the different driving lever connecting shaft fixing holes 91.
