Specifically, the moving direction of the substrate is as follows: the coating material is drawn to the outer side of a tension roller 12 from bottom to top through a feeding roller set 11, drawn to the lower side of an upper feeding roller 13 around the tension roller 12, drawn to the upper side of a coating roller 15 along the bottom of the upper feeding roller 13, pressed to be attached to the surface of the coating roller 15 by a pressing roller 16 from the upper side of the coating roller 15, rotated to suck the coating material in a coating groove 14 and reversely coated on the base material, then drawn to the outer side of a discharge roller 19, finally drawn to a boosting roller 20 around the discharge roller 19, and drawn to the next process through the boosting roller 20. The tension roller 12 is driven by a magnetic powder brake, and can output a certain braking force according to a set value when working; the power-assisted roller 20 is driven by a motor and can output a certain braking force according to a set value when working; the tension roller 12 arranged at the front section of the coating roller 15 and the power-assisted roller 20 arranged at the rear section of the coating roller 15 provide braking force, so that the tension of the base material during operation is increased, the phenomenon that the base material is not tightly attached to the surface of the coating roller 15 when the front section is overfed or the rear section is slowly conveyed to cause gluing is avoided, and the coating quality is prevented from being influenced due to uneven coating. Moreover, the pressing roller 16 presses the base material, so that the base material can be driven to directly contact and attach with the coating roller 15, and the tension of the base material can be increased to a certain degree to enable the attachment to be tighter. Meanwhile, the comma scraper 17 scrapes off the over-thick coating layer on the surface of the coating roller 15, so as to ensure that the coating layer on the substrate is uniformly distributed; the gap between the comma scraper 17 and the coating roller 15 can be adjusted through the scraper gap adjusting mechanism 18, so that the thickness of the coating layer on the surface of the coating roller 15 can be adjusted, and the production requirement standard can be met. The utility model discloses a contrary mode of scribbling, complete machine tension operation, the tape transport is stable, and coating distribution is even, guarantees coating quality, and adjustable coating thickness.

Further, the scraper gap adjustment mechanism 18 includes a guide rail 181, a slide table 182, an adjustment screw 183, and a micrometer 184; the guide rail 181 is fixed on the frame 10, the sliding table 182 is slidably connected to the guide rail 181, the comma scraper 17 and the micrometer 184 are respectively disposed on the sliding table 182, the adjusting screw 183 is used for driving the sliding table 182 to slide, and the adjusting screw 183 is provided with a rotation stopping member 185.

Specifically, both ends of the comma scraper 17 are provided with the scraper gap adjusting mechanisms 18, and both ends of the comma scraper 17 are distributed on the corresponding sliding tables 182. When the gap between the comma scraper 17 is adjusted, the comma scraper 17 moves towards the coating roller 15 side by rotating the adjusting screw 183, moves to a limit position and stops, and corrects the zero position of the dial indicator to enable the pointer of the dial indicator to point to the zero position. Then the adjusting screw 183 is adjusted in the opposite direction to retract to a proper position, and the number of the dial indicator is the retraction gap. The calculation formula of the finished thickness and the scraper gap after coating and baking is as follows: gap thickness glue solid content = finished thickness. After the gap adjustment is completed, the rotation stopping piece 185 fastens the adjusting screw 183 to prevent the looseness from generating errors.

Further, a lifting cylinder 141 and a guide post 142 are arranged at the bottom of the coating material tank 14, a linear bearing 101 is arranged on the frame 10, the guide post 142 is arranged in the linear bearing 101 in a penetrating manner, and the lifting cylinder 141 drives the coating material tank 14 to lift. The pneumatic lifting function of the coating tank 14 is realized, and the liquid level is convenient to adjust.

Further, an overflow port 143 is provided in the coating tank 14. When the liquid level in the paint tank 14 is too high, automatic overflow is started.

Further, the swaging roller 16 includes a first pinch roller 161 and a second pinch roller 162, a fixing adjusting plate 163 is connected to both ends of the first pinch roller 161 and the second pinch roller 162, and the fixing adjusting plate 163 is connected with a pinch roller lifting device 164 to drive the first pinch roller 161 and the second pinch roller 162 to lift. The first pressing wheel 161 and the second pressing wheel 162 are respectively pressed on the base materials at two sides of the coating roller 15, so that the base materials are more tightly attached to the surface of the coating roller 15 and the tension of the base materials is larger, and the coating is uniform; and through the lift of pressing material running roller 16, can adjust the machine and avoid substrate joint department more convenient and fast.

Further, a height adjuster 165 is provided on the fixing adjustment plate 163. The device is used for adjusting the height of the pressing roller 16 and controlling the fit tightness between the pressing roller 16 and the coating roller 15 so as to adapt to the coating requirements with different thicknesses.
