[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 A multi-angle adjustable air knife dryer includes an air knife 15. A connecting block 2 is fixedly mounted on the top of the air knife 15. A concave seat 21 is rotatably mounted on the outer side of the connecting block 2. A second rotating shaft 144 and a first rotating shaft 143 are fixedly mounted on the front and rear sides of the connecting block 2, respectively. A first through hole and a second through hole are respectively opened on the front and rear sides of the concave seat 21. The front side of the second rotating shaft 144 passes through the first through hole and is connected to a worm gear 22. A worm 23 is meshed on the top of the worm gear 22. A handwheel 24 is fixedly mounted on the left side of the worm 23. Two sets of support sleeves 25 are evenly rotated and sleeved on the outer side of the worm 23. The two sets of support sleeves 25 are evenly fixed on the front side of the concave seat 21, supporting the rotation of the worm 23 through the support sleeves 25. The first rotating shaft 143... The rotating part is located in the second through hole. The connecting block 2 is supported by the first rotating shaft 143. The rotating handwheel 24 drives the worm gear 23 to rotate, which in turn drives the worm wheel 22 to rotate. The worm wheel 22 drives the connecting block 2 to rotate via the second rotating shaft 144. The connecting block 2 drives the air knife 15 to tilt at an angle. A horizontal adjustment component is placed on the top of the concave seat 21. A vertical adjustment component is placed on the outside of the horizontal adjustment component. A valve 16 is connected to the front of the air knife 15. The air inlet of the valve 16 is connected to a diversion pipe 17. The air inlet of the diversion pipe 17 is connected to a high-pressure blower 18. The high-speed airflow generated by the high-pressure blower 18 is input into the air knife 15 through the diversion pipe 17 and the valve 16, and is sprayed out by the air knife 15 to dry the surface of the material.

[0020] The lateral adjustment assembly includes a second guide rail 13. A first convex groove is formed at the bottom of the second guide rail 13, and a first sliding groove is formed through the top of the first convex groove. A first convex block 141 is evenly slidably disposed within the first convex groove, and a first threaded hole is formed at the top of the first convex block 141. A second bolt 14 is slidably disposed within the first sliding groove, and the bottom of the second bolt 14 passes through the first sliding groove and is screwed into the first threaded hole. An anti-slip ring 142 is fixedly disposed at the bottom of the bolt head of the second bolt 14, and the anti-slip ring 142 is fixedly disposed on the outer ring of the bolt screw of the second bolt 14. The bottom of the anti-slip ring 142 is in contact with the top of the second guide rail 13. An air knife 15 is fixedly disposed. At the bottom of the first convex block 141, the air knife 15 is located at the bottom of the second guide rail 13. After loosening the second bolt 14, the first convex block 141 can be moved left and right by pulling the second bolt 14. The first convex block 141 drives the air knife 15 at the bottom of the connecting block 2 to move left and right through the concave seat 21. When the left and right position of the air knife 15 is determined, the second bolt 14 can be tightened, thereby driving the anti-slip ring 142 to fit tightly with the second guide rail 13. The friction between the two is used to fix the position of the air knife 15. The longitudinal adjustment component includes the first guide rail 1, and a set of first guide rails 1 are opened on opposite sides of the two sets of first guide rails 1. The device has two convex grooves, each containing a slidable second convex block 19. Each of the two sets of second convex blocks 19 has a set of second threaded holes on its opposite sides. Each of the two sets of first guide rails 1 has a third through hole evenly spaced on its opposite sides. A first bolt 12 is rotatably installed in the third through hole and screwed into the second threaded hole. Each of the front and rear sides of the first guide rail 1 has a set of support feet 11 fixedly installed. The outer wall of each support foot 11 has a fixing lug 111 fixedly installed. Bolts are used to pass through the fixing lugs 111 and screw into the threaded holes on the material conveyor, thus fixing the device to the material conveyor. A second guide rail 13 is fixedly installed on each of the two sets of second convex blocks. Between 19, after unscrewing the first bolt 12, the second guide rail 13 can be moved up and down along the second convex groove of the first guide rail 1. The second convex block 19 assists the second guide rail 13 in moving up and down stably. When the second guide rail 13 moves up and down, it will drive the bottom air knife 15 to move up and down. When the second threaded hole on the second convex block 19 is aligned with the third through hole at different positions on the first guide rail 1, the first bolt 12 can be screwed through the third through hole and the second threaded hole to fix the position height of the second guide rail 13, thereby completing the position height adjustment of the air knife 15. The second guide rail 13 is located between the two sets of first guide rails 1.

[0021] Working principle: The device is fixed to the material conveyor by bolts through the fixing lug 111 and threaded into the threaded hole. High-speed airflow generated by the high-pressure blower 18 flows through the diverter pipe 17 and valve 16 into the air knife 15, where it dries the material surface. Closing valve 16 stops the airflow from the air knife 15. Turning handwheel 24 rotates the worm gear 23, which in turn rotates the worm wheel 22. The worm wheel 22, via the second rotating shaft 144, rotates the connecting block 2, causing the air knife 15 to tilt. Loosening the second bolt 14 allows the first convex block 141 to move left and right by pulling it. The first convex block 141, via the concave seat 21, moves the air knife 15 at the bottom of the connecting block 2. Move the air knife 15 left and right. Once the left and right position of the air knife 15 is determined, tighten the second bolt 14 to make the anti-slip ring 142 and the second guide rail 13 fit tightly together. Use the friction between the two to fix the position of the air knife 15. After unscrewing the first bolt 12, the second guide rail 13 can be moved up and down along the second convex groove of the first guide rail 1. The second convex block 19 assists the second guide rail 13 to move up and down stably. When the second guide rail 13 moves up and down, it will drive the air knife 15 at its bottom to move up and down. When the second threaded hole on the second convex block 19 is aligned with the third through hole at a different position on the first guide rail 1, the first bolt 12 can be screwed through the third through hole and the second threaded hole to fix the position height of the second guide rail 13, thereby completing the position height adjustment of the air knife 15.
