10. A process for coating thermal paper, characterized in that the coating system of thermal paper according to any one of claims 1-9 comprises the following specific steps:

pulling out one end of a substrate placed on a discharging roller (3), sequentially passing through four guide rollers (6), winding on a material collecting roller (2), and uniformly coating a heat-sensitive substance on the substrate through a conveying assembly to ensure that the heat-sensitive material coated on the substrate is uniformly distributed;

step two, the cleaning component and the dust collection component cooperate with an exhaust fan (21) to absorb impurities such as dust on two sides of the coating system, and meanwhile, the scraps and floccules on the base material are cleaned and absorbed;

step three, the impurities absorbed later can be blocked by the oily filter screen (31) and stay in the shell (20), and along with the operation of a system, the anti-blocking component can also clear the oily filter screen (31) so as to prevent the impurities from blocking filter holes on the oily filter screen (31);

and step four, the thermal paper after being uniformly coated enters a dryer (5) for drying, and finally the thermal paper is rolled up by a material receiving roller (2), and the thermal paper rolled up on the material receiving roller (2) can be taken down after the processing is finished.
