In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the structures involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] Example:

[0024] See also Figure 1-5 The utility model provides a technical solution: a flame retardant polyurethane resin dry coating equipment for fabric processing, comprising a shell 1, a coating structure 3 is installed on the right side of the front end of the shell 1, a feeding roller 4 is installed on the right side of the coating structure 3, a hot chamber 2 is arranged on the left side of the front end of the shell 1, a cooling chamber 7 is arranged below the hot chamber 2, the feeding roller 4 feeds the fabric 13 into the coating structure 3, the hot chamber 2, the cooling chamber 7 and the discharging roller 9 in sequence, the fabric 13 passing through the hot chamber 2 is respectively installed with a drying structure 5 on the left and right sides, and the fabric 13 passing through the cooling chamber 7 is respectively installed with an air cooling structure 8 on the left and right sides, the coated fabric 13 is heated and dried by the heat generated by the drying structure 5, and the air cooling structure 8 is installed on the left and right sides. Excessive heat will cause the flame retardant polyurethane resin to expand, and then the flame retardant polyurethane resin will more easily penetrate into the gap of the fabric cloth 13, and then the heat will be quickly taken away by the air cooling structure 8 of the cooling chamber 7, and the moisture will also be taken away. The rapid temperature loss will also cause the flame retardant polyurethane resin that penetrates into the fabric cloth 13 to shrink, and then the flame retardant polyurethane resin and the fabric will be more tightly combined, which is conducive to using the principle of thermal expansion and contraction to make the combination effect of the flame retardant polyurethane resin and the fabric better, and is conducive to greatly reducing the shedding between the flame retardant polyurethane resin and the fabric. At the same time, through the heating structure 5 in the hot chamber 2 and the air cooling structure 8 in the cooling chamber 7, the moisture of the flame retardant polyurethane resin coating on the fabric cloth 13 can be quickly lost, thereby improving the quality of the fabric coating;

[0025] A conveying structure 6 is provided between the hot chamber 2 and the cooling chamber 7 , and the fabric cloth 13 is conveyed from the hot chamber 2 into the cooling chamber 7 through the conveying structure 6 .

[0026] Among them, a paint tube 10 is installed inside the coating structure 3, and the bottom of the paint tube 10 is discharged through the bottom nozzle through the pressurizing structure. The direction of the nozzle corresponds to the fabric cloth 13. The pressurizing structure can use a pump to pressurize the paint, and then the flame retardant polyurethane resin is combined with the fabric cloth 13 through the nozzle.

[0027] A scraping structure 11 is installed on the left side of the coating structure 3 , and the flame retardant polyurethane resin on the fabric 13 is scraped and leveled by the scraping structure 11 , so that the flame retardant polyurethane resin coating is evenly combined with the fabric 13 .

[0028] Among them, an electric heating plate 14 is installed in the heating structure 5. The electric heating plate 14 has a built-in resistance wire to generate heat by doing work. The current passes through the resistance wire in the electric heating plate 14 to release heat by doing work, and then the heat passes through the heating structure 5 to the corresponding fabric cloth 13 that has completed the coating.

[0029] Among them, multiple fans 15 are evenly installed inside the air cooling structure 8, and the air flow directions of the fans 15 are all toward the fabric cloth 13. By starting the multiple fans 15 in the air cooling structure 8, the air flow is accelerated to rapidly reduce the temperature of the fabric cloth 13, and then the temperature of the flame retardant polyurethane resin coating also rapidly reduces.

[0030] The discharging roller 9 is located below the coating structure 3 , and the discharging roller 9 assists the fabric cloth 13 in discharging.

[0031] A scraper 12 is provided at the bottom of the leveling structure 11 , and the flame-retardant polyurethane resin on the fabric 13 is leveled by the scraper 12 .

[0032] The working principle of the embodiment of the utility model is as follows: the fabric cloth 13 is passed through the coating structure 3, the heat chamber 2, the cooling chamber 7 and the discharging roller 9 of the device, the coating in the coating tube 10 is pressurized by the pressurizing structure, and then the flame retardant polyurethane resin is combined with the fabric cloth 13 through the nozzle, and the flame retardant polyurethane resin on the fabric cloth 13 is scraped flat by the scraper 12 of the flattening structure 11, so that the flame retardant polyurethane resin coating is flat, and the coated fabric cloth 13 is heated and dried by the heat generated by the drying structure 5, and the hot drying structure passes the current through the resistance wire in the electric heating plate 14 to do work and release heat, and then the heat passes through the drying structure 11. The structure 5 corresponds to the coated fabric 13. The heat will cause the flame-retardant polyurethane resin to expand, and the flame-retardant polyurethane resin will penetrate into the gaps of the fabric 13 more easily. The heat will be quickly taken away by the air-cooling structure 8 of the cooling chamber 7. By starting multiple fans 15 in the air-cooling structure 8, the temperature of the fabric 13 will drop rapidly by accelerating the air flow, and the temperature of the flame-retardant polyurethane resin coating will also drop rapidly, and moisture will also be taken away. The rapid temperature loss will also cause the flame-retardant polyurethane resin that penetrates into the fabric 13 to shrink, and the flame-retardant polyurethane resin and the fabric will be more tightly bonded.
