Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

A kind of carbonless copy paper coating machine of the present invention, as shown in Figure 1, it comprises successively connected paper delivery device, coating head 1, drying device, back water coating device 2, ironing device, calender 3 1. The delivery device, in order to accurately control the coating machine, also includes a microprocessor, a motor that drives the paper tape 8 to advance, and the microprocessor is electrically connected to the motor. After the paper tape 8 is sent out from the paper delivery device, Enter between the rubber rollers of the coating head 1, as shown in Figure 2, the upper side of the paper strip 8 is coated with paint, and then enters the drying device.
