Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal spraying technology, specifically a planar thermal spraying device. Background Technology
[0002] Thermal spraying is a surface engineering technology that uses a high-temperature heat source to heat coating materials to a molten or semi-molten state, then atomizes them with a high-speed airflow and sprays them onto the surface of a workpiece to form a coating with specific properties. Its core purpose is to improve the wear resistance, corrosion resistance, high-temperature resistance, insulation, conductivity, and other properties of a workpiece, or to give it a specific appearance, by preparing a functional or protective coating on the substrate surface.
[0003] During the thermal spraying process, the spraying liquid is contained in a spraying tank. By injecting medium- or high-pressure gas into the spraying tank, the spraying liquid is sprayed out of the tank to achieve the spraying operation. However, the spraying liquid may precipitate or clump inside the spraying tank, causing the spraying liquid to fail to spray out smoothly. Utility Model Content

Detailed Implementation
[0019] 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.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a planar thermal spraying device, including a mounting frame 1 and a housing 12. An adjusting rod 2 is fixedly welded to the lower inner side of the mounting frame 1. Mounting blocks 3 are slidably mounted inside both sides of the adjusting rod 2. An mounting rod 4 is fixedly welded to the lower part of the mounting blocks 3. A fixing ring 5 is fixedly welded to one side of the mounting rod 4. A spray can 6 is fitted inside the fixing ring 5. An air inlet pipe 17 is fixedly welded to one side of the upper part of the spray can 6. Medium- and high-pressure gas is supplied to the spray can 6 through the air inlet pipe 17, causing the spraying liquid in the spray can 6 to be sprayed out, achieving thermal spraying. For spraying, a rotating shaft 7 is rotatably installed on the upper middle part of the spray tank 6. Several sets of stirring rods 9 are fixedly welded to the lower outer side of the rotating shaft 7. A connecting gear 8 is fixedly welded to the upper part of the rotating shaft 7. A rack 10 is meshed with one side of the connecting gear 8. Adjusting boxes 11 are slidably installed on the outer sides of both ends of the rack 10. The adjusting boxes 11 are fixedly welded to the inner wall of the outer shell 12. When the mounting frame 1 moves back and forth, the rack 10 meshes with the connecting gear 8 and rotates, thereby driving the stirring rods 9 to rotate through the rotating shaft 7, thereby continuously stirring the spray liquid in the spray tank 6.
[0021] Mounting bracket 1 has lugs 16 fixedly welded to both sides. A first threaded rod 14 is threaded onto the inner wall of one lug 16, and the first threaded rod 14 is rotatably connected to the inner wall of the outer casing 12. A motor 13 is mounted on the outer flange of the outer casing 12, and the power end of the motor 13 is connected to the first threaded rod 14 via a coupling. A sliding rod 15 is slidably connected inside the other lug 16, with both ends of the sliding rod 15 fixedly welded to the inside of the outer casing 12. The motor 13 drives the first threaded rod 14, causing the lug 16 to move back and forth along the sliding rod 15, thus enabling the spray can 6 to reciprocate spraying the surface, ensuring complete coating. (Rear adjustment) A partition plate 23 is fixedly welded to the middle of the box 11. Second threaded rods 22 are rotatably mounted on both sides of the partition plate 23 and the inner wall of the adjusting box 11. The second threaded rods 22 are threaded into the rack 10. By rotating the second threaded rods 22 on both sides, the rack 10 moves along the inside of the adjusting box 11. Several sets of position holes 27 are opened on the upper part of the adjusting rod 2. A locking rod 28 that matches the position holes 27 is slidably mounted inside the upper side of the mounting block 3. By moving the mounting block 3 along the outside of the adjusting rod 2, the distance between the two spray cans 6 can be changed. The locking rod 28 is inserted into the corresponding position hole 27 to position the mounting block 3. The locking rod 28 is fixedly welded to a fixing plate 29. A spring 30 is fixedly welded between the fixing plate 29 and the mounting block 3. The spring 30 is sleeved on the outside of the locking rod 28. When the locking rod 28 is disengaged from the position hole 27, the spring 30 is stretched. When the locking rod 28 is aligned with the position hole 27, the spring 30 pulls the fixing plate 29, causing the locking rod 28 to automatically insert into the position hole 27, improving the ease of operation. A threaded ring 19 is installed on the internal threads of the lower side of the spray can 6. A spray head 18 is fixedly welded to the lower part of the threaded ring 19, which facilitates opening the spray can 6 for internal maintenance and replacement. A connecting frame 20 is fixedly welded to the upper side of the ring 19. A support cylinder 21 is fixedly welded to the upper part of the middle side of the connecting frame 20, which is directly opposite to the rotating shaft 7, to support and position the lower part of the rotating shaft 7. Connecting pieces 24 are fixedly welded to both sides of the fixing ring 5. Two sets of third threaded rods 25 are fixedly welded to one end of one connecting piece 24. The third threaded rods 25 are slidably installed inside the connecting piece 24 on the other side. A locking nut 26 is threadedly connected to the outer side of the third threaded rod 25. By rotating the locking nut 26, the fixing ring 5 is pressed to move along the third threaded rod 25, so that the position between the two fixing rings 5 is reduced, and the spray can 6 is effectively clamped.
[0022] Working principle: When in use, the motor 13 drives the first threaded rod 14, which in turn moves the lug 16 back and forth along the sliding rod 15. This allows the spray can 6 to reciprocate and spray the plane, ensuring that the plane is completely coated. When the mounting bracket 1 moves back and forth, the rack 10 meshes with the connecting gear 8 and rotates, which in turn drives the stirring rod 9 to rotate through the rotating shaft 7, thereby continuously stirring the spray liquid in the spray can 6. By moving the mounting block 3 along the outside of the adjusting rod 2 and inserting the locking rod 28 into the corresponding position hole 27, the position of the mounting block 3 is fixed, which can change the distance between the two spray cans 6. According to the atomization under different air pressures, the spray liquid is evenly sprayed on the plane surface. By rotating the second threaded rods 22 on both sides respectively, the rack 10 is moved along the inside of the adjusting box 11, so that the rack 10 and the connecting gear 8 are engaged.
