In the above, the type of the servo motor 511 is CH/V, and the type of the hydraulic cylinder 51 is SDW-98, which is a single stroke.

And those not described in detail in this specification are well within the skill of those in the art.

When the liquid film scraper is used, when the liquid film scraper scrapes a liquid film, a power supply of the servo motor 511 is firstly switched on, so that the servo motor 511 drives the worm 534 to rotate, the worm 534 drives the worm wheel 533 which is in meshing connection with the worm 534 to rotate, the worm wheel 533 drives the screw 531 to rotate, the screw 531 drives the rack block 532 to move, the rack block 532 drives the first gear 535 which is in meshing connection with the rack block, the first gear 535 drives the rotary disc 59 to rotate, the rotary disc 59 drives the adjusting plate 510 to do eccentric motion, under the movable connection of the adjusting plate 510, the adjusting plate 510 drives the sliding blocks 56 at two ends of the connecting plate 57 to slide on the limiting shaft 55, then under the rotation of the scraper 54 and the movable connection of the adjusting rod 58, the connecting plate 57 drives the adjusting rod 58 to rotate along with the movement of the connecting plate 57, so as to adjust the angle of the scraper 54, when the angle of the scraper 54 is adjusted to a proper position, the operation of the servo motor 511 is stopped, the hydraulic cylinder 51 drives the shell plate 52 to move downwards, and further drives the scraper 54 to move downwards, the distance between the scraper 54 and the conveying steel belt 4 is adjusted to be equal to the thickness distance of a film to be processed, and then under the movement of the conveying steel belt 4, the solution on the conveying steel belt 4 can be scraped into a liquid film by the lower side of the scraper 54;

further, when the film is rolled, the handle 744 is rotated, the handle 744 drives the double-thread screw 743 to rotate, the double-thread screw 743 drives the two fixing plates 741 to move, and the tooth patterns on the outer surface of the double-thread screw 743 and located on the two sides of the center are opposite, so that the moving directions of the two fixing plates 741 are opposite under the rotation of the double-thread screw 743, and the two U-shaped plates 742 are driven to move, the distance between the two U-shaped plates 742 is equal to the width of the film, and the rolled film is located between the two U-shaped plates 742, so that the film can be rolled up onto the U-shaped plates 742 in order;

further, under the rotation of the movable plate 747, the guide rods 7413 are moved upwards, the guide rods 7413 drive the two movable plates 747 to rotate respectively, because the center of the arc-shaped rod 748 and the center of the rotation of the arc-shaped rod 748 are located at the same position, the guide rod 7413 will drive the movable plate 747 to slide on the arc-shaped rod 748 under the elasticity of the spring 749, so that the upper end of the clamping plate 7411 on the movable plate 747 is disengaged from the toothed block on the second gear 7412, then the position of the guide roller 746 on the limit plate 745 is adjusted by rotating the limit plate 745 to ensure that the lower surface of the film is supported against the limit plate to ensure the tension degree of the film, after the adjustment, when the guide rod 7413 is fed, the spring 749 will make the movable plate 747 return to the original position, so that the upper end of the clamping plate 7411 on the movable plate 747 is clamped in the toothed block on the second gear 7412, so that the gear wheel 7412 is fixed, the gear wheel 7412 is prevented from rotating, and the guiding stability of the guide roller 746 on the limiting plate 745 is further ensured.
