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 a part of the present utility model. These are some examples, not all examples. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] Referring to Figures 1-3, one embodiment of this utility model provides a plasma cladding feeding device, including a body 1. A support leg is fixedly connected to the lower half of the outer wall of the body 1 to support the entire device. The bottom of the body 1 is tapered, wider at the top and narrower at the bottom, to guide the plasma cladding material. A feeding chamber 2 for feeding material into the body 1 is fixedly connected through the upper surface of the body 1. The top of the feeding chamber 2 is open. A door 3 is provided on the front surface of the feeding chamber 2. The door 3 is equipped with a handle, a latch, and a hinge, allowing for flexible opening after unlocking and stable closing. The handle, latch, and hinge are existing technologies and can be implemented by those skilled in the art. A discharge pipe 4 for discharging plasma cladding material is fixedly connected through the lower surface of the body 1. A solenoid valve 5 is provided at one end of the discharge pipe 4 near the body 1. The solenoid valve 5 is existing technology and can be implemented by those skilled in the art. The solenoid valve 5 can control the discharge pipe 4. The feed hopper 2 is equipped with a stirring component 600 at its top, which facilitates stirring of the plasma cladding material. This prevents the plasma cladding material from accumulating and adhering, ensuring its fluidity and allowing for smooth discharge. The feed hopper 2 is also equipped with a screening component 700, which can screen plasma cladding materials of different particle sizes. Different particle sizes of plasma cladding materials have a significant impact on the processing, including the melting rate and the performance of the formed coating.

[0021] Refer to Figure 1- Figure 2 The stirring assembly 600 includes a support plate 601 for supporting a drive motor 602. The support plate 601 is fixedly connected to the top of the inner surface of the feeding bin 2. The drive motor 602 is disposed on the upper surface of the support plate 601. The drive motor 602 is prior art and can be implemented by those skilled in the art. The output shaft of the drive motor 602 is fixedly connected to a connecting rod 603. After the drive motor 602 is started, it can drive the connecting rod 603 to rotate. The lower surface of the connecting rod 603 is slidably connected to a stirring shaft 604. The middle section of the outer wall of the stirring shaft 604 is fixedly connected to a stirring blade 605 for stirring the plasma cladding material. Multiple sets of stirring blades 605 are evenly distributed on the outer wall of the stirring shaft 604. The bottom end of the stirring shaft 604 is fixedly connected to an auger 606. The connecting rod 603, the stirring shaft 604, and the auger 606 will all rotate synchronously.

[0022] Referring to Figures 1-2, the centers of the connecting rod 603, the stirring shaft 604, and the auger 606 are all on the same axis, which can ensure that the stirring force is balanced. The inner wall of the connecting rod 603 is provided with a groove, and the top of the outer wall of the stirring shaft 604 is fixedly connected with a sliding key, which is slidably connected to the inner wall of the groove.

[0023] Referring to Figures 2-4, the screening assembly 700 includes a screen plate 701 for screening plasma cladding raw materials. The screen plate 701 is slidably connected to the inner wall of the feeding bin 2 and slides longitudinally. A brush plate 702 for cleaning the upper surface of the screen plate 701 is fixedly connected to the upper section of the outer wall of the stirring shaft 604. The brush plate 702 can sweep the plasma cladding raw materials to prevent accumulation. A top plate 706 for driving the brush plate 702 longitudinally is fixedly connected to the upper section of the outer wall of the stirring shaft 604 below the brush plate 702. The screen plate 701 is located between the top plate 706 and the brush plate 702. An arc-shaped groove 705 for positioning the stirring shaft 604 is opened on the upper section of the outer wall of the stirring shaft 604 below the top plate 706. A positioning plate 703 is fixedly connected to the front surface of the feeding bin 2, and a positioning plate 705 for positioning the stirring shaft 604 is fixedly connected to the rear surface of the positioning plate 703. The positioning block 704 is used for positioning, and the positioning block 704 and the arc groove 705 are matched.

[0024] Refer to Figure 2- Figure 4 The stirring shaft 604 penetrates the inner surface of the sieve plate 701, and the stirring shaft 604 and the sieve plate... The centers of 701 are on the same axis. The top plate 706 is located below the sieve plate 701. The upper surface of the top plate 706 is in contact with the lower surface of the sieve plate 701. The arc-shaped groove 705 is a ring-shaped wave with its ends connected. When the stirring shaft 604 rotates, the arc-shaped groove 705 will be squeezed by the positioning block 704, which will cause the stirring shaft 604 to vibrate longitudinally and in turn cause the sieve plate 701 to vibrate, thus preventing the plasma cladding material from accumulating in the mesh of the sieve plate 701. The rear end of the positioning block 704 is set as an arc surface, and the positioning block 704 slides on the inner wall of the arc-shaped groove 705.

[0025] Working principle: First, the plasma cladding raw material is poured into the feeding bin 2. The raw material falls onto the sieve plate 701, which sieves the raw material and separates it into different particle sizes. The raw material that meets the particle size requirements falls through the holes of the sieve plate 701, while large particles are blocked. The drive motor 602 can be started to drive the connecting rod 603 and the stirring shaft 604 to rotate. When the stirring shaft 604 rotates, it drives the stirring blade 605 to stir the raw material, preventing it from agglomerating or adhering and ensuring its fluidity. The auger 606 at the bottom further pushes the raw material towards the discharge pipe 4 to ensure smooth conveying.

[0026] When the stirring shaft 604 rotates, the arc-shaped groove 705 is squeezed by the positioning block 704. Since the arc-shaped groove 705 is annular and wavy, the stirring shaft 604 will be squeezed by the positioning block 704 when it rotates, generating longitudinal reciprocating vibration. Under the action of the top plate 706, the screen plate 701 vibrates up and down, accelerating the screening of raw materials and preventing raw materials from clogging the mesh on the screen plate 701. The rotating stirring shaft 604 will also drive the brush plate 702 to rotate, sweeping the raw materials to avoid accumulation and ensure the screening effect.

[0027] When it is necessary to discharge the ion-clad raw material, the solenoid valve 5 is opened, and the raw material will be discharged from the discharge pipe 4 to the next processing step under the push of the auger 606.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
