[0039] Embodiment 1: A tablecloth roll is mounted on a tablecloth mounting rod 1, and the tablecloth output from the tablecloth roll is transported to a pair of flattening rollers 5 through a first raw material roller 4 for flattening. The flattened tablecloth is sequentially transported to a tensioning raw material rod 8 and a fourth raw material roller 9 through a second raw material roller 6 and a third raw material roller 7. The tablecloth output from the fourth raw material roller 9 enters between a printing press roller 2 and a coating roller 3. The printing raw material output from an extruder 27 is smeared on the outer wall of the coating roller 3, and a pattern is printed on the outer wall of the coating roller 3. Driven by the cylinder 32, the printing press roller 2 presses the tablecloth on the coating roller 3. As the printing press roller 2 and the coating roller 3 rotate, the pattern is continuously printed on the tablecloth. The printed tablecloth is sequentially transported through a first coating roller 10, a second coating roller 11, a third coating roller 12 and a fourth coating roller 13, and is transported through a first cooling air knife 2 during the transport process. 8 and the second cooling air knife 29 are air-cooled to fix the printing, and then the tablecloth is guided and transported to between the hot stamping roller 18 and the heated hot stamping roller 24 by the first hot stamping feed roller 14, the second hot stamping feed roller 15, the third hot stamping feed roller 16 and the fourth hot stamping feed roller 17. The hot stamping roll is installed on the hot stamping roll mounting rod 22. The hot stamping paper output by the hot stamping roll is guided and transported to between the heated hot stamping roller 24 and the hot stamping roller 18 by the first hot stamping guide roller 23. The hot stamping paper is located under the tablecloth. Driven by the cylinder 32, the hot stamping roller 18 moves down and presses on the heated hot stamping roller 24 to thermally transfer the hot stamping paper to the tablecloth. The hot stamped tablecloth is output in sequence by the first hot stamping discharge roller 19, the second hot stamping discharge roller 20 and the third hot stamping discharge roller 21, and is air-cooled by the third cooling air knife 30 and the fourth cooling air knife 31 during the output process. The waste paper generated after the hot stamping is transported to the waste winding roller 26 through the second hot stamping guide roller 25 for winding and collection.

[0040] After the hot stamping, the tablecloth enters the tearing edge feeding roller 41. During the conveying process, the staff tears off the edge materials on both sides of the tablecloth, and then guides it through the transfer column 47 and puts it between the edge material winding roller 42 and the edge material pressing roller 43. The edge material winding roller 42 rotates clockwise, and the edge material pressing roller 43 rotates counterclockwise. Since the edge material pressing roller 43 is a rubber roller, the friction force is increased, and the edge material is continuously pulled downward, and the edge material is continuously removed and collected in the edge material receiving box 49. After the edge material is torn off, the tablecloth is conveyed to the subsequent station along a group of tearing edge discharging rollers. When the edge material tearing system gets stuck, or edge material needs to be put in before production, the adjusting cylinder piston rod is retracted, and the edge material pressing roller 43 is away from the edge material winding roller 42, so that the distance between the edge material pressing roller 43 and the edge material winding roller 42 becomes larger, which is convenient for inspection or putting in edge material. After the inspection or putting in of edge material is completed, the adjusting cylinder piston rod is extended, and the edge material pressing roller 43 is pressed on the table cloth edge material on the edge material winding roller 42.

[0041] The tablecloth with the edges torn off is stacked on the tablecloth placement table 62, and the tablecloth is transported by the first feeding roller 53, the second feeding roller 54, the third feeding roller 55, the fourth feeding roller 56, the fifth feeding roller 57 and the sixth feeding roller 58 in sequence, wherein the first feeding roller 53 and the third feeding roller 55 are lower support rollers, the second feeding roller 54 and the fourth feeding roller 56 are upper pressure tensioning rollers, the fifth feeding roller 57 and the sixth feeding roller 58 are vertical tensioning rollers during material discharge, and the tablecloth raw material is provided with equidistant roll indentations to facilitate the subsequent tearing of the tablecloth into strips along the indentations. The tablecloth outputted by the sixth feeding roller 58 enters the reeling gap. Under the downward squeezing and rotating force of the upper discharging roller 51, the tablecloth is torn into multiple staggered strips of cloth and outputted. A part of the strips of cloth enters the upper winding roller group, and the other part of the strips of cloth enters the lower winding roller group. The first guide roller 63 plays the role of supporting the strips of cloth, and the second guide roller 59 plays the role of pressing down and tensioning the strips of cloth. The reeling roller 60 rotates, and a group of strips of cloth are arranged in sequence at equal intervals and are respectively wound on the reeling roller 60. After winding, the reeling roller 60 is removed, and a group of strips of cloth on it are removed in sequence. A pair of reeling roller groups work simultaneously, which improves the reeling efficiency. The discharging roller 51 is driven to rise or fall by the longitudinal adjustment cylinder. When the upper discharging roller 51 is raised, it can be inspected and guided to place the tablecloth. When the upper discharging roller 51 is lowered, it presses on the tablecloth on the top of the lower discharging roller 52 to reel.
