The scraper group 8 includes a scraper adjusting mechanism 9 provided on the front side of the scraper group 8 and located between the side plates 2 for adjusting the position of the scraper group 8 .

[0040] The working principle of the present invention is as follows: when the ceramic film passes through the pressure roller 4 and the coating roller 3, the driving cylinder 22 can adjust the height of the pressure roller 4, thereby adjusting the distance between the pressure roller 4 and the coating roller 3; the height of the coating material trough 5 can be adjusted by the height adjustment mechanism 6, so that the coating in the coating material trough 5 and the coating roller 3 can be separated and coated; the scraper group 8 can be adjusted to move forward and backward, up and down, and rotate through the scraper adjustment mechanism 9, so that the scraper group 8 can freely control the coating thickness and position of the coating roller 3, and has strong applicability.

[0042] The working principle of the height adjustment mechanism 6 driving the coating material trough 5 to rise and fall is as follows: when the height of the coating material trough 5 needs to be adjusted, the hand wheel is turned to drive the rotating wheel rod 61 to rotate, thereby driving the worm gear 62 fixed on the rotating wheel rod 61, and the worm wheel 64 meshing with the worm gear 62 rotates accordingly, thereby driving the rotating rod 63 to rotate. Since the rack rod 68 slidingly arranged in the driving block 65 is meshed with the gear 67 rotatably arranged in the rotating groove 66, and the gear 67 is sleeved and fixed on the rotating rod 63, the rotation of the rotating rod 63 will drive the rack rod 68 to move up and down in the driving block 65, and then drive the coating material trough 5 to rise and fall through the fixed sleeve plate 69.

[0043] Combined with Figure 3 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10As shown, the scraper adjustment mechanism 9 includes a rotating rod 91 rotatably arranged at the front part of the side plate 2, a mounting rod 92 fixed between the side plates 2 is arranged on the upper side of the rotating rod 91, a scraper height adjustment unit 93 is arranged on the rotating rod 91, and a scraper shaft 94 is connected to the top end of the scraper height adjustment unit 93 in a lifting manner.

A rack rod 937 meshing with the gear 933 is provided in the driving block 931 for sliding up and down, and the top of the rack rod 937 is sleeved and fixed with the scraper shaft 94.

[0044] The working principle of the scraper height adjustment unit 93 for adjusting the height of the scraper group 8 is as follows: when the height of the scraper group 8 needs to be adjusted, the hand wheel is turned to drive the rotating wheel rod 2 934 to rotate, and the worm 2 935 sleeved and fixed on the rotating wheel rod 2 934 rotates accordingly, thereby driving the worm wheel 2 936 meshing with the worm 2 935 to rotate, and the worm wheel 2 936 drives the rotating rod 2 91 to rotate. When the rotating rod 2 91 rotates, it drives the gear 2 933 sleeved and fixed thereon to rotate in the rotating groove 2 932, thereby driving the rack rod 2 937 meshing with the gear 2 933 to move up and down in the driving block 2 931, and the rack rod 2 937 drives the scraper shaft 94 to move, thereby adjusting the height of the scraper group 8.

[0045] Combined with Figure 8 , Attachment Fig.11 As shown, a scraper angle adjustment unit 95 is provided on the scraper shaft 94, and a fixed plate 96 is connected to the top of the scraper angle adjustment unit 95.

[0046] The working principle of the scraper angle adjustment unit 95 for changing the horizontal angle of the scraper group 8 is as follows: the cylinder 2 953 is driven to work, and the telescopic shaft of the cylinder 2 953 is telescopically moved. Since the scraper seat 951 is rotatably set on the scraper shaft 94, and the telescopic shaft end of the cylinder 2 953 is hinged to the front end of the scraper seat 951, the cylinder 2 953 drives the scraper seat 951 to rotate on the scraper shaft 94, thereby driving the fixed plate 96 to rotate, so that the scraper group 8 connected to the fixed plate 96 can realize the change of the horizontal angle and adjust the docking position with the coating roller 3.

[0047] Combined with Figure 7 , Attachment Figure 8 , Attachment Fig.12 , Attachment Fig.13 , Attachment Fig.14 and attached Fig.15 As shown, a pair of movable grooves are reserved on the fixed plate 96, and a scraper group 8 is slidably connected in the movable grooves.

The rear end of the propulsion shaft 975 is fixedly set on the connecting plate at the front end of the scraper group 8, and the rod bodies at the front and rear ends are both sleeved A pair of rotating blocks 977 are connected, and rotating arms 978 are rotatably provided between the adjacent rotating blocks 977 on the same side, and a transmission rod 979 is connected between the front and rear rotating arms 978. The crank 973 is fixedly connected to the rotating arm 978 on the same side, and a matching gear 9710 meshing with the inner gear ring seat 974 is rotatably provided on the transmission rod 979. A worm 9711 is provided at the rear end of the matching gear 9710, and a worm 9712 matching with the worm 9711 is sleeved and fixed in the middle of the propulsion shaft 975. The outer walls of the worm 9711 and the worm 9712 are both provided with thread grooves that mesh with each other and surround each other.

Since a transmission rod 979 is rotatably provided between the front and rear rotating arms 978, and a matching gear 9710 meshing with the inner gear ring seat 974 is rotatably provided on the transmission rod 979, the matching gear 9710 rotates on the transmission rod 979 with the gear ring inside the inner gear ring seat 974, and the worm 1 9711 arranged at the rear end of the matching gear 9710 cooperates with the worm 2 9712 in the middle of the propulsion shaft 975, driving the propulsion shaft 975 to move slowly forward and backward, and the rear end of the propulsion shaft 975 is fixed on the connecting plate at the front end of the scraper group 8, thereby driving the scraper group 8 to move slowly forward and backward, adjusting the distance between it and the coating roller 3, so that the thickness of the ceramic film coating can be changed according to demand. Compared with conventional propulsion mechanisms such as cylinders and electric push rods, the planetary gear deceleration moving unit 97 can control the scraper group 8 to move slowly back and forth, and accurately control the thickness of the ceramic film coating.
