Technical Field

[0001] This application relates to the field of powder supply technology, and more specifically, to a powder material supply mechanism for spraying. Background Technology

[0002] Spray coating technology is a deposition technique based on aerodynamics. It offers numerous advantages, such as low spraying temperature, strong coating adhesion, uniform and dense coating, low oxide content, and good electrical and thermal conductivity. This makes spray coating a promising field with broad applications in chemical, automotive, aerospace, shipbuilding, electronics, machinery, and papermaking industries. It can be used to produce and repair components such as turbine blades, pistons, bearings, cylinders, and valves. Furthermore, spray coating technology has important applications in the biomedical field, such as the preparation of metal coatings, polymer coatings, ceramic coatings, and antibacterial coatings. These applications require the assistance of a powder material supply device.

[0003] In existing technologies, some powder may clump together during powder mixing due to factors such as humid weather, resulting in poor powder performance. Additionally, some powder may adhere to the inner wall of the mixing tank, leading to powder waste.

[0004] Therefore, a powder material supply mechanism for spraying is provided. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a powder material supply mechanism for spraying, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder material supply mechanism for spraying, comprising a support carriage on which a mixing tank is mounted. A motor is fixedly connected to the top of the mixing tank via a support plate. A stirring rod is fixedly connected to the output shaft of the motor. Multiple sets of stirring blades are mounted on the outer side of the stirring rod. A crushing assembly is mounted inside the mixing tank. The crushing assembly includes an extrusion block, which is fixedly connected to the inner wall of the mixing tank. A rectangular groove is formed on the surface of the stirring rod. A crushing plate is slidably connected inside the rectangular groove. A protrusion is fixedly connected to the top of the crushing plate. A spring is elastically connected between the crushing plate and the bottom of the rectangular groove.

[0007] Preferably, there are six sets of extrusion blocks, and all six sets of extrusion blocks are fixedly connected to the inner wall of the mixing tank via connecting rods.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0025] See Figures 1-4 This embodiment provides a powder material supply mechanism for spraying, including a support carriage 1, on which a mixing tank 2 is mounted. A motor 3 is fixedly connected to the top of the mixing tank 2 via a support plate. A stirring rod 4 is fixedly connected to the output shaft of the motor 3. Multiple sets of stirring blades 5 are mounted on the outer side of the stirring rod 4. A crushing component 6 is mounted inside the mixing tank 2. The crushing component 6 includes an extrusion block 605, which is fixedly connected to the inner wall of the mixing tank 2. A rectangular groove 601 is formed on the surface of the stirring rod 4. A crushing plate 603 is slidably connected inside the rectangular groove 601. A protrusion 604 is fixedly connected to the top of the crushing plate 603. A spring 602 is elastically connected between the crushing plate 603 and the bottom of the rectangular groove 601. A total of six sets of extrusion blocks 605 are provided. All six sets of extrusion blocks 605 are fixedly connected to the inner wall of the mixing tank 2 via connecting rods. All six sets of extrusion blocks 605 are located on the movement trajectory of the protrusion 604. Multiple sets of spikes are mounted on the bottom of the crushing plate 603.

[0026] In practical use, the above-mentioned equipment first needs to be moved to a suitable position. Then, powder is poured into the feed inlet at the top of the mixing tank 2. Next, the motor 3 is turned on, causing its output shaft to drive the stirring rod 4 to rotate. The rotation of the stirring rod 4 then drives multiple sets of stirring blades 5 to rotate synchronously, thus uniformly mixing the powder inside the mixing tank 2. When encountering humid weather or other reasons, the powder is prone to clumping. Therefore, when the stirring rod 4 rotates, it drives the crushing plate 603 to rotate synchronously. Then, when the crushing plate 603 rotates... During the process, the protrusions 604 at the top of the crushing plate 603 can sequentially contact the extrusion blocks 605 inside the mixing tank 2. When the protrusions 604 contact a set of extrusion blocks 605, the protrusions 604 are squeezed downwards, and the crushing plate 603 also slides downwards. At this time, the spring 602 is squeezed by the crushing plate 603 and is elastically compressed. When the rotation reaches the point where the protrusions 604 and the extrusion blocks 605 are no longer in contact, the spring 602, under its own rebound force, drives the crushing plate 603 to automatically reset and slide upwards. This repetition allows the crushing plate 603 to drive multiple sets of spikes to move up and down repeatedly, crushing the agglomerated powder. Example

[0027] See Figures 1-4 Based on Embodiment 1, a scraper assembly 7 is fitted on the outer side of the stirring rod 4. The scraper assembly 7 includes a sliding rod 702. A rectangular groove 706 is provided on the outer side of the stirring rod 4. The sliding rod 702 is slidably connected inside the rectangular groove 706. A spring 704 is elastically connected between the sliding rod 702 and the bottom of the inner side of the rectangular groove 706. A scraper 703 is fixedly connected to the end of the sliding rod 702 away from the rectangular groove 706 by bolts. A sliding ball 705 is fixedly connected to the top of the scraper 703 by a fixing rod. A circular hole groove 701 is provided at the top of the inner side of the stirring tank 2. There are six sets of circular hole grooves 701. The sliding ball 705 is semi-circular in shape.

[0028] In practical use, the above-mentioned equipment uses the rotation of the stirring rod 4 to drive the scraper 703 to scrape the inner wall of the mixing tank. At the same time, as the scraper 703 rotates, the sliding ball 705 can correspond with the round hole groove 701. When rotating again, the sliding ball 705 can disengage from the round hole groove 701, and the spring 704 is elastically compressed, causing the sliding rod 702 to slide down. This reciprocating motion causes the scraper 703 to move up and down, thereby solving the problem of scraping the powder adhering to the inner wall of the mixing tank.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
