Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying equipment technology, specifically to a spraying device for preparing coatings by spraying. Background Technology
[0002] As we all know, with the continuous advancement of science and technology, the requirements for materials are getting higher and higher. How to improve the performance of materials (such as corrosion resistance, wear resistance, high temperature resistance, etc.) has become a hot research topic. Since material instability and failure are more likely to occur on their surface, physical or chemical methods are usually used to attach a coating of a certain thickness to the material surface to improve the material's corrosion resistance, wear resistance, and high temperature oxidation resistance, thereby resisting the damage of the external environment to the material and improving the material's service life.
[0003] Spraying equipment is required when applying coatings. However, most existing spraying equipment has fixed spray heads. Therefore, when spraying cylindrical materials, the position of the material needs to be changed multiple times to achieve uniform spraying. This increases the workload of operators and is prone to uneven spraying. Utility Model Content

[0026] 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.
[0027] See Figure 1 A spraying device for preparing a coating by spraying includes a frame 1, an operating frame 2 disposed inside the frame 1, an adjustment component 5, a driving component 6, a surrounding component 3 and a spraying component 4 respectively disposed on both sides of the frame 1.
[0028] First, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the adjustment component 5 includes a support plate 501 and a first spring 507 disposed on the outside of the frame 1. The support plate 501 has an open movable groove 511 inside, and a movable column 502 is slidably disposed inside the movable groove 511. A swing rod 508 is rotatably disposed on the outside of the movable column 502. The swing rod 508 is inclined, and the two sets of swing rods 508 are inclined in opposite directions. A horizontal plate 505 is disposed at the end of the first spring 507 away from the frame 1. A connecting rod 506 and a placement plate 509 are disposed on the side of the horizontal plate 505 close to the first spring 507. Two sets of fixed shafts 510 are disposed inside the placement plate 509, and the side of the swing rod 508 away from the movable column 502 is rotatably disposed on the outside of the fixed shafts 510 and the placement plate 509.
[0029] Specifically, when the horizontal plate 505 is pushed upward, the first spring 507 will be stretched. When the horizontal plate 505 is no longer pushed upward, the first spring 507 will drive the surrounding assembly 3 and the spraying assembly 4 to move back by bouncing the horizontal plate 505, thereby ensuring the reuse of the device.
[0030] Then, refer to Figure 5 In this embodiment, to prevent the movable column 502 from detaching from the movable groove 511, a balance bar 513 is provided on the inner wall of the movable groove 511. The movable column 502 is slidably disposed on the outside of the balance bar 513. Thus, the balance bar 513 can block the movable column 502, thereby preventing the device from malfunctioning due to the movable column 502 detaching from the movable groove 511.
[0031] Secondly, see Figure 1 and Figure 4 In this embodiment, in order to maintain the balance of the horizontal plate 505, two sets of limiting rods 504 are provided on the side of the frame 1 near the horizontal plate 505. The horizontal plate 505 is slidably disposed on the outside of the limiting rods 504. The limiting rods 504 are polygonal limiting rods with three or more sides. Thus, on the one hand, the limiting rods 504 maintain the balance of the horizontal plate 505 during movement, preventing the horizontal plate 505 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the horizontal plate 505. On the other hand, the limiting rods 504 restrict the direction of the horizontal plate 505, preventing the device from failing due to misalignment of the horizontal plate 505, and ensuring the normal use of the device.
[0032] Meanwhile, in order to prevent the horizontal plate 505 from disengaging from the limiting rod 504, a blocking plate 503 is provided on the outside of the limiting rod 504, and the blocking plate 503 is located above the horizontal plate 505. Thus, the blocking plate 503 can block the horizontal plate 505 and prevent the horizontal plate 505 from moving excessively and disengaging from the limiting rod 504.
[0033] Again, see Figure 5 In this embodiment, in order to make the moving column 502 move back quickly, a second spring 512 is provided on the outside of the moving column 502, and the end of the second spring 512 away from the moving column 502 is provided on the inner wall of the movable groove 511. Thus, when the moving column 502 moves, it will squeeze the second spring 512. When the swing rod 508 is no longer pushed, the second spring 512 will bounce the moving column 502 back to the initial position quickly.
[0034] When the swing rod 508 is pushed, the side of the swing rod 508 connected to the moving column 502 will push the moving column 502 to move laterally. At the same time, the other side of the swing rod 508 will push the fixed shaft 510 to move upward. When the fixed shaft 510 moves upward, it will push the placement plate 509 to move the horizontal plate 505 upward. When the horizontal plate 505 moves upward, it will drive the connecting rod 506 to move the fixed block 301 upward. The upward movement of the fixed block 301 will drive the spray head 404 to move upward, thereby changing the spraying position of the spray head 404.
[0035] In addition, see Figures 1 to 3 In this embodiment, the surrounding component 3 includes a fixing block 301 disposed at one end of two sets of connecting rods 506. A rotating motor 305 is disposed on the side of the fixing block 301 near the connecting rod 506. A groove 304 is provided on the side of the fixing block 301 away from the rotating motor 305. The output end of the rotating motor 305 extends into the groove 304 and is keyed to the rotating column 303. A connecting plate 302 is disposed on the outer side of the rotating column 303. A spraying component 4 is disposed on the side of the connecting plate 302 away from the rotating column 303.
[0036] After the rotating motor 305 is turned on, its output end will drive the rotating column 303 to rotate. The rotation of the rotating column 303 will drive the connecting plate 302 to rotate. When the connecting plate 302 rotates, it will drive the spraying assembly 4 to rotate around the rotating column 303 as the axis, so that the spraying assembly 4 can surround the operating frame 2.
[0037] Furthermore, see Figures 1 to 3In this embodiment, the spraying assembly 4 includes a support column 402 disposed on one side of the connecting plate 302. A disc 403 is disposed at the end of the support column 402 away from the connecting plate 302. A nozzle 404 is disposed on the side of the disc 403 away from the support column 402. A connecting frame 401 is disposed on the outside of the support column 402. A paint tank 406 communicating with the nozzle 404 is disposed on the outside of the connecting frame 401. The paint tank 406 is used to store paint. When the nozzle 404 is turned on, the paint in the paint tank 406 will be sprayed out.
[0038] Meanwhile, in order to maintain the balance of the connecting frame 401 during rotation, a groove 306 is provided on the outside of the fixed block 301. The side of the connecting frame 401 away from the paint can 406 is fixedly set with a slider 405 that is slidably arranged in the groove 306. Thus, the slider 405 can be used to maintain the balance of the connecting frame 401 during rotation.
[0039] Finally, see Figure 1 , Figure 7 and Figure 8 In this embodiment, the drive assembly 6 includes a rotary motor 604 disposed outside the fixed block 301. The rotary motor 604 is a bidirectional motor, and its output end can rotate forward or backward. The output end of the rotary motor 604 is key-connected to a threaded tube 605. A sleeve 602 is screwed onto the outside of the threaded tube 605. When the threaded tube 605 rotates, it will drive the sleeve 602 screwed onto its outside to move linearly. A mounting plate 603 is disposed on the outside of the sleeve 602. A movable plate 606 is disposed on the side of the mounting plate 603 away from the sleeve 602. Two sets of top rollers 607 are disposed on the side of the movable plate 606 close to the mounting plate 603. One end of the top roller 607 is rotatably connected inside the movable plate 606, and a rotating disk 608 is welded to the end of the top roller 607 located inside the movable plate 606. The diameter of the rotating disk 608 is larger than the diameter of the top roller 607, and the outside of the top roller 607 is in contact with the outside of the swing rod 508.
[0040] When the sleeve 602 moves down, the mounting plate 603 will drive the movable plate 606 and the top roller 607 to move down. When the top roller 607 moves down, it will push the swing rod 508. At the same time, the top roller 607 will roll on the outside of the swing rod 508. At this time, the side of the swing rod 508 connected to the moving column 502 will push the moving column 502 to move laterally, while the other side of the swing rod 508 will push the fixed shaft 510 to move up.
[0041] Furthermore, in order to protect the rotary motor 604 and the threaded tube 605, a protective cover 601 is provided on the outside of the support plate 501, and the protective cover 601 is located on the outside of the rotary motor 604 and the threaded tube 605, thereby protecting the rotary motor 604 and the threaded tube 605 through the protective cover 601.
[0042] The spraying device for preparing the coating uses the cooperation between the swing rod 508 and the fixed shaft 510. When the swing rod 508 swings, one side of it will push the placement plate 509 and the horizontal plate 505 by pushing the fixed shaft 510. When the horizontal plate 505 moves, it will change the position of the spray head 404, so that the device can spray different positions of the material, increase the spraying range of the device, avoid uneven spraying, and is suitable for widespread application.
[0043] Working principle:
[0044] When using this coating preparation device, first place the device in the desired position, then install the material to be sprayed on the operating frame 2 for spraying. The specific operation is as follows: turn on the nozzle 404 to spray the paint from the paint tank 406, then turn on the rotating motor 305 so that its output end drives the rotating column 303 to rotate. The rotation of the rotating column 303 will drive the connecting plate 302 to rotate. When the connecting plate 302 rotates, it will rotate around the rotating column 303 as the axis. The rotation of the connecting plate 302 will drive the support column 402 to rotate. When the support column 402 rotates, it will drive the nozzle 404 to spray around the material by driving the disc 403.
[0045] Finally, adjust the height of the nozzle 404. Specifically, turn on the rotary motor 604 so that its output end drives the threaded tube 605 to rotate. The rotation of the threaded tube 605 will cause the outer threaded sleeve 602 to move linearly. As the sleeve 602 moves, it will drive the movable plate 606 and the top roller 607 to move via the mounting plate 603. When the top roller 607 moves downward, it will push against the outer side of the swing rod 508. At the same time, the top roller 607 will roll on the outer side of the swing rod 508. At this time, the swing rod 508 and the moving column 5... One side of the 02 connection will push the moving column 502 to move laterally, while the other side of the swing rod 508 will push the fixed shaft 510 to move upward. When the fixed shaft 510 moves upward, it will push the placement plate 509 to move the horizontal plate 505 upward. When the horizontal plate 505 moves upward, it will drive the connecting rod 506 to move the fixed block 301 upward. The upward movement of the fixed block 301 will drive the spray head 404 to move upward, thereby changing the spraying position of the spray head 404 and enabling the material to be uniformly sprayed.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
