Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a thermal spray powder supply device. Background Technology

[0002] Chinese Patent CN222119356U, authorized publication number, discloses a thermal spray powder supply device, comprising: a powder supply pipe and a powder storage box. A main partition plate and a guide plate are fixedly connected inside the powder supply pipe. Both the main partition plate and the powder storage box are movably connected to a drive shaft via sealed bearings. A fan blade is fixedly connected to the lower end of the drive shaft, and a dredging component, a stirring blade, and a fixing frame are fixedly connected to the upper end of the drive shaft. Cleaning plates are symmetrically connected to both ends of the fixing frame. Powder outlet holes are symmetrically opened at the bottom of the powder storage box, and a pressure relief pipe is fixedly connected to the upper surface of the powder storage box. A limiting rod is slidably connected to the upper surface of the pressure relief pipe through a through hole. A sealing plate is fixedly connected to the lower end of the limiting rod, and the sealing plate is slidably connected inside the pressure relief pipe via the limiting rod. A three-way pipe is connected to the upper surface of the powder storage box via a branch pipe. This invention, through the cooperation of the powder supply pipe, branch pipe, drive shaft, main partition plate, guide plate, and dredging plate, enables the supply device to spray powder evenly, effectively reducing the probability of powder flow obstruction.

[0003] However, the above technical solutions still have the following shortcomings in actual use. The cleaning plate in the solution can only clean the inner wall of the powder storage box. It is difficult to reach the residual powder on the main partition plate, guide plate and powder supply pipe. Long-term use will form stubborn powder accumulation, affecting the smoothness of powder feeding. In addition, the device is not designed with a quick disassembly structure. When changing the powder type, it needs to be disassembled as a whole. It cannot adapt to the scenario of alternating production of multiple powder types and has low maintenance efficiency. Therefore, we propose a thermal spray powder supply device to solve the above problems. Utility Model Content

If the specific posture changes, the directional indicator will also change accordingly.

[0020] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a thermal spraying powder supply device includes a powder supply pipe 1, a powder storage cylinder 2 installed at the top of the powder supply pipe 1, an air pump 3 installed at the side end of the powder supply pipe 1, a drive shaft 10 installed inside the powder storage cylinder 2, multiple sets of stirring blades 11 arranged outside the drive shaft 10, a telescopic sleeve 4 installed between the powder supply pipe 1 and the air pump 3, a cover plate 6 connected to the upper end of the telescopic sleeve 4 through a branch pipe 5, the cover plate 6 placed at the top of the powder supply pipe 1, a mounting seat 8 arranged outside the upper end of the telescopic sleeve 4, a rotating cylinder 9 rotatably connected to the top of the mounting seat 8, the side end of the rotating cylinder 9 connected to the cover plate 6, a top plate 13 installed at the top of the drive shaft 10, a threaded post 14 installed in the middle of the top of the top of the top plate 13, a positioning hole 17 arranged outside the threaded post 14, cleaning plates 12 installed on both sides of the positioning hole 17, and a threaded sleeve 18 threadedly connected to the top of the threaded post 14.

[0023] By installing the cleaning plate 12 on the sleeve 16 and quickly connecting the sleeve 16 to the outside of the threaded column 14, and fixing the sleeve 16 with the threaded sleeve 18, it is easy to quickly disassemble and replace the cleaning plate 12. Furthermore, through the cooperation of the telescopic sleeve rod 4 and the rotating cylinder 9, the cover plate 6 can be quickly opened and closed, which facilitates maintenance and powder type replacement and improves the convenience of equipment use.

[0024] In other embodiments, the cleaning plate 12 is made of a flexible wear-resistant material, and its outer edge is in interference contact with the inner wall of the powder storage cylinder 2;

[0025] This design allows the cleaning plate 12 to be made of polyurethane flexible wear-resistant material. Because of its elasticity, it can always fit tightly against the inner curved surface of the powder storage cylinder 2 under the drive of the transmission shaft 10. Even if the cylinder wall is slightly uneven, it can still achieve scraping without dead angles.

[0026] In other embodiments, two sets of handles 7 are installed at the top of the cover plate 6;

[0027] This design allows the handle 7 to be fixed to the top of the cover plate 6, enabling users to easily open or close the cover plate 6 by pulling the handle 7. Combined with the rotating connection of the rotating cylinder 9, it enables quick disassembly.

[0028] In other embodiments, multiple sets of positioning rods 15 are installed at equal intervals at the top edge of the top plate 13, and multiple sets of positioning holes 17 are opened at equal intervals on the positioning hole 17, with the multiple sets of positioning rods 15 passing through the interior of the positioning hole 17.

[0029] This design allows the positioning rod 15 to be fixed on the top plate 13 and pass through the positioning hole 17 on the sleeve 16, preventing the sleeve 16 from shifting during rotation and ensuring that the cleaning plate 12 always fits against the inner wall of the powder storage cylinder 2. This improves the stability and cleaning effect of the cleaning plate 12 and avoids the problem of incomplete cleaning caused by the shaking of the sleeve 16.

[0030] In other embodiments, multiple sets of anti-slip protrusions are installed at equal intervals on the outside of the threaded sleeve 18;

[0031] This design increases the friction on the surface of the threaded sleeve 18 by adding anti-slip ridges, making it easier for users to manually tighten or loosen the threaded sleeve 18.

[0032] In other embodiments, an octagonal protrusion 19 is mounted on the top of the threaded sleeve 18;

[0033] This design allows the octagonal protrusion 19 to be tightened or loosened using standard tools, providing greater torque transmission capability, ensuring the fastening reliability of the threaded sleeve 18, making it suitable for high-intensity working environments, and further simplifying maintenance operations.

[0034] This utility model provides a thermal spraying powder supply device, the specific working principle of which is as follows:

[0035] The powder is stored in the powder storage cylinder 2. The operation of the drive shaft 10 is the same as that in the comparative scheme, so it will not be described in detail. The drive shaft 10 makes the stirring blade 11 continuously stir the powder. Then the air pump 3 injects airflow into the powder storage cylinder 2 through the branch pipe 5. The powder enters the powder supply pipe 1 for output under the action of the airflow.

[0036] The cleaning plate 12 is fixed on both sides of the sleeve 16 and scrapes off the residual powder on the inner wall of the powder storage cylinder 2 as the drive shaft 10 rotates. The positioning rod 15 and the positioning hole 17 ensure that the cleaning plate 12 maintains a stable position and improves the cleaning effect.

[0037] When it is necessary to change the powder type or perform cleaning, the user can pull the cover plate 6 with the handle 7 and quickly open the powder storage cylinder 2 by using the rotating connection of the rotating cylinder 9. At the same time, the sleeve 16 and the cleaning plate 12 can be removed by loosening the threaded sleeve 18 for thorough cleaning.

[0038] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0039] 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.
