[0002] Plasma powder cladding technology, as an efficient surface strengthening and repair process, is widely used in petrochemical, mining machinery, power equipment and other fields. Its core is to melt alloy powder and deposit it on the surface of the workpiece through a plasma arc to form a wear-resistant and corrosion-resistant cladding layer. As a key component of this technology, the powder feeding device undertakes the important task of accurately and stably delivering the cladding powder to the plasma arc area. Its performance directly affects the compositional uniformity, bonding strength and surface quality of the cladding layer.

[0003] In traditional plasma powder cladding machines, the connection between the powder storage tank and the powder delivery tank often relies on manual operation. However, the powder delivery tank is made of glass and is quite heavy after being filled with powder. When manually connecting the tanks, uneven operating force or visual deviation can easily lead to misalignment of the interface, causing wear or deformation of the connection joint or even crushing damage, thus reducing the service life. To address these issues, a new plasma powder cladding machine powder delivery device is proposed. Utility Model Content

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.

[0030] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a plasma powder cladding machine powder feeding device, comprising a body 1, which is the main body of an intelligent powder feeder. A powder storage tank 2 is installed on the upper part of the body 1. A connection port 21 is fixedly installed on the top of the powder storage tank 2. After the connection port 21 is aligned and connected with the bottom interface of the powder feeding tank 22, the powder inside the powder feeding tank 22 can be continuously fed into the powder storage tank 2. The powder feeding tank 22 is positioned above the connection port 21, and a positioning component 3 is provided on the outside of the powder feeding tank 22. The positioning component 3 is used for... To ensure precise alignment between the powder delivery tank 22 and the powder storage tank 2, preventing accidental misalignment during manual installation and potential damage to the interface, the positioning component 3 includes a support ring 31 and a mounting frame 34 fixedly connected to the rear surface of the machine body 1. The mounting frame 34 is used to mount the support frame 32. The lower part of the powder delivery tank 22 is inserted into the inner wall of the support ring 31. The support frame 32 is fixedly mounted inside the mounting frame 34 by bolts, providing support. A slider 36 is slidably connected to the front surface of the support frame 32 near the upper part, and the slider 36 is used to support the support ring 31.

[0031] Furthermore, the support ring 31 is fixedly connected to the front surface of the slider 36, and a second sliding plate 39 is fixedly connected to the upper surface of the slider 36. The second sliding plate 39 drives the slider 36 and the first sliding plate 33 to move while providing support. The second sliding plate 39 penetrates the upper surface of the support frame 32, and the first sliding plate 33 is fixedly connected to its upper surface. The first sliding plate 33 supports the limiting plate 35. A groove 37 is formed on the front surface of the first sliding plate 33 extending to the rear surface. The groove 37 provides space for the limiting plate 35 to move while providing support. The inner wall of the groove 37 extends through and slides... A limiting plate 35 is connected to the powder feeding tank 22. The limiting plate 35 presses against the upper surface of the powder feeding tank 22 and cooperates with the support ring 31 to support and limit the powder feeding tank 22. The powder feeding tank 22 is fixedly installed between the support ring 31 and the limiting plate 35. The limiting plate 35 contacts and presses against the top of the powder feeding tank 22. The rear of the support frame 32 is provided with an installation component 4 for driving the positioning component 3 to move vertically. The installation component 4 drives the positioning component 3 to move so that the powder feeding tank 22 is accurately aligned with the connection port 21, thereby preventing shaking caused by manual alignment and installation, which may lead to damage to the connection.

[0032] Reference Figure 2 , Figure 3 and Figure 4The support frame 32 is inserted into the inner wall of the mounting frame 34 and fixedly installed on the upper surface of the machine body 1. The bottom of the support ring 31 is conical, which can fit and support the powder feeding tank 22. The front surface of the support frame 32 is provided with a positioning groove for the vertical sliding of the slider 36. The positioning groove provides space for the vertical sliding of the slider 36. Both the slider 36 and the positioning groove are T-shaped. The T-shape can increase the stability of the movement of the slider 36 and the support ring 31. The rear surface of the limiting plate 35 is fixedly connected to the positioning plate 38. The positioning plate 38 and the protrusion restrict the movement of the limiting plate 35 and prevent it from falling off. The limiting plate 35 is U-shaped and the opening is located on the front surface. The U-shape can press against the top of the powder feeding tank 22. The left and right surfaces of the limiting plate 35 are fixedly connected to the front end with protrusions.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The installation component 4 includes a guide block 41, which drives the slide plate 39 to move. The guide block 41 is fixedly connected to the rear surface of the slide plate 39. The guide block 41 is slidably connected vertically to the rear surface of the support frame 32. A fixing block 43 is fixedly connected to the rear surface of the support frame 32 near the top. The fixing block 43 supports the screw 42. The middle part of the fixing block 43 is rotatably connected to the screw 42 from top to bottom. The lower thread of the screw 42 is threadedly connected to the guide block 41. The top of the screw 42 is fixedly connected to a turntable 44 on the upper surface of the fixing block 43. The turntable 44 is rotatably connected to the upper surface of the fixing block 43. By rotating the turntable 44, the screw 42 is driven to rotate. Through the threaded engagement between the screw 42 and the guide block 41, the guide block 41 moves vertically, driving the powder feeding tank 22 to move downward, so that the bottom end of the powder feeding tank 22 is accurately and stably connected to the connection port 21.

[0034] Working principle: During use, when installing the powder feeding tank 22, insert the bottom of the powder feeding tank 22, which is filled with powder, into the support ring 31. Then, push the limiting plate 35 forward so that it contacts the top of the powder feeding tank 22 and presses it down, thus supporting and limiting the powder feeding tank 22. At this time, rotating the turntable 44 drives the screw 42 to rotate and engage with the guide block 41. The guide block 41 then drives the slide plate 39 to move downward. Simultaneously, the slide plate 39 drives the T-shaped slider 36 to slide vertically along the positioning groove, and simultaneously drives the slide plate 33 to move. By using the sliding plate 33 and the support ring 31 to fix and stabilize the powder feeding tank 22, it can be moved downwards. After the powder feeding tank 22 moves downwards and is precisely aligned with the connection port 21, the bottom of the powder feeding tank 22 and the connection port 21 are finally accurately and stably connected. At this time, after the powder feeding tank 22 is connected to the connection port 21, the powder can be conveyed downwards into the powder storage tank 2, so that the powder can be continuously and uninterruptedly fed. This ensures the reliability of the powder conveying process and prevents the connection port 21 from swinging and being damaged when manually connecting the powder feeding tank 22, thereby improving the accuracy and reliability of the installation.
