[0024] Next, with reference to the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0025] As Figures 1 - 3A coating and ink scraping structure of a coating machine shown in the figure includes a frame 10. A coating roller 20 is rotatably arranged on the frame 10. A pressure roller is arranged on one side of the coating roller 20. A channel for the PCB board to pass through is arranged between the coating roller 20 and the pressure roller. Ink scraping structures 30 are respectively arranged at both ends of the coating roller 20 on the frame 10.

[0026] On the basis of the above structure, the ink scraping structure 30 includes a mounting plate 31 and an ink scraping plate 32. The mounting plate 31 is fixedly connected to the frame 10. The ink scraping plate 32 is fixedly arranged on the mounting plate 31, and the ink scraping part of the ink scraping plate 32 abuts against the end of the PCB board.

[0027] On the basis of the above structure, the ink scraping plate 32 includes a horizontal section and an inclined section. The included angle between the horizontal section and the inclined section is an obtuse angle. The horizontal section is fixedly connected to the mounting plate 31, and the inclined section forms the ink scraping part.

[0028] On the basis of the above structure, the ink scraping plate 32 is horizontally movably arranged on the mounting plate 31. Specifically, a first chute 33 is opened on the mounting plate 31, a second chute 34 communicating with the first chute 33 is opened on the horizontal section of the ink scraping plate 32, and a positioning member 35 for locking the mounting plate 31 and the ink scraping plate 32 is arranged through the first chute 33 and the second chute 34.

[0029] On the basis of the above structure, the outer shapes of the first chute 33 and the second chute 34 are in a runway shape, and the first chute 33 and the second chute 34 are arranged vertically. The design that the outer shapes of the first chute 33 and the second chute 34 are in a runway shape and are vertical allows the ink scraping plate 32 to be adjusted in two directions of the x-axis and the y-axis, and can better adapt to the requirements of ink scraping.

[0030] On the basis of the above structure, the positioning member 35 is a bolt. The screw part of the bolt passes through the first chute 33 and the second chute 34 and is locked and fixed by a nut. When adjustment is needed, loosen the nut, and the movement of the screw part of the bolt in the first chute 33 and the second chute 34 can be realized.

[0031] On the basis of the above structure, an ink trough 40 is further opened on the frame 10. The ink trough 40 is located below the coating roller 20 and the ink scraping structure 30 and is used for receiving the dripping and scraped ink. A drain hole 41 is opened at the bottom of the ink trough 40. In this way, the dripping and scraped ink is centrally collected through the ink trough 40 and discharged in time through the drain hole 41.

[0032] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
