Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, specifically to a laser cladding powder container powder changing device. Background Technology

[0002] Laser cladding is a surface modification technology that uses a high-energy laser beam to rapidly fuse alloy powder with the surface of a substrate, forming a coating with specific properties. This can improve the substrate's surface properties, such as wear resistance, corrosion resistance, and high-temperature resistance. Laser cladding powder mixing refers to the process of uniformly mixing various metal or ceramic powders of different compositions in a predetermined ratio before cladding. Its core lies in using physical stirring and vibration to fully disperse the powder particles, ensuring the uniformity of the coating composition during laser cladding. This directly affects the microstructure and performance of the cladding layer.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Existing powder changing devices are mostly single-container powder supply devices, which require machine shutdown and disassembly for powder changing, resulting in low efficiency. Furthermore, the positioning accuracy is insufficient when manually switching between multiple powders, which can easily cause cross-contamination of powders and reduce the efficiency and quality of laser cladding. Utility Model Content

[0005] The purpose of this invention is to provide a powder changing device for various powder containers using laser cladding, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cladding powder container changing device, including powder containers, a plurality of powder containers having a connecting channel at their bottom ends, the bottom ends of the connecting channels vertically penetrating the top of a rotating mechanism, the bottom ends of the rotating mechanism being rotatably connected to the top of a supporting turntable, the bottom ends of the supporting turntable having a supporting plate, a preparation container being snapped into the inner wall of the supporting plate, and a common hopper vertically penetrating one side of the top of the preparation container;

[0007] The bottom end of the rotating mechanism extends vertically through the middle of the top of the support frame.

[0008] The beneficial effects of this utility model are as follows: the inclined feeding pipe in the connecting channel allows the powder to slide smoothly by gravity, and its flow valve accurately controls the conveying volume, which can ensure stable powder supply and achieve uniform and continuous powder feeding, prevent blockage and adjust the speed. In the rotating mechanism, the handle drives the rotating rod to slide in the rotating groove through the rotating shaft and rotating plate, which can achieve precise positioning of the powder container and realize quick powder replacement.

[0009] To ensure smooth powder flow and flexible control of powder delivery, the amount of powder entering the preparation container must be precisely controlled to avoid powder waste or over-delivery:

[0010] The connection channel is further configured such that: the top end of the connection channel is located at the bottom end of the powder container; a feeding pipe is inserted into the outer wall of the connection channel near the common hopper; and a flow valve is installed on the outer wall of the top end of the connection channel.

[0011] By adopting the above technical solution, the flow valve can flexibly control the amount of powder conveyed. By adjusting the opening of the flow valve, the amount of powder entering the preparation container can be precisely controlled, avoiding powder waste or excessive conveying. This structural design makes the powder conveying process smooth and adjustable as needed, providing a stable powder supply for subsequent laser cladding work.

[0012] To ensure stable powder conveying, the feed pipe in the connecting channel is inclined, allowing the powder to slide smoothly down using gravity.

[0013] A further setting is made: the feeding tube is inclined.

[0014] By adopting the above technical solution, the feeding pipe is inclined, which allows the powder to slide smoothly with the help of gravity, so that the powder in the powder container is uniformly and continuously transported to the common hopper, ensuring the stability of powder conveying.

[0015] To achieve precise rotational positioning of multiple powder containers, enable rapid switching between different types of powder, and meet the requirement of alternating use of multiple powders during laser cladding:

[0016] The rotating mechanism is further configured such that: the rotating mechanism includes a handle, the bottom end of the handle is provided with a rotating shaft, the bottom end of the rotating shaft is vertically inserted through the middle of the top of the support frame, the bottom end of the rotating shaft is inserted with a rotating plate, and the bottom of the rotating plate is provided with several rotating rods.

[0017] By adopting the above technical solution, the handle in the rotating mechanism can drive the rotating plate to rotate through the rotating shaft. The rotating rod at the bottom of the rotating plate slides in the rotating groove of the supporting turntable, thereby realizing the precise rotation and positioning of the powder container. This allows the connecting channel of the target powder container to be accurately aligned with the common hopper. This design can quickly switch between different types of powders and has precise positioning, improving powder changing efficiency and meeting the needs of alternating use of multiple powders in the laser cladding process.

[0018] To ensure a more stable rotation mechanism by coordinating the rotating groove and the rotating rod, preventing the device from shaking or shifting during rotation, and guaranteeing the accuracy and stability of the powder container during rotational alignment:

[0019] The configuration is further defined as follows: a rotating groove is provided on the top of the support turntable, the rotating rod is rotatably connected to the rotating groove, and a plurality of supporting feet are provided on the bottom of the support turntable, with the bottom ends of the plurality of supporting feet located on the top of the support plate.

[0020] By adopting the above technical solution, the cooperation between the rotating groove and the rotating rod makes the rotating mechanism more stable when rotating, and the support foot provides a solid support for the entire device, ensuring that the device will not shake or deviate during the rotation process, thereby ensuring the accuracy and stability of the powder container during the rotation alignment process.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 4 A laser cladding powder container changing device includes a powder container 1, a number of powder containers 1 with a connecting channel 2 at the bottom, the bottom of the connecting channel 2 vertically penetrating the top of a rotating mechanism 3, the bottom of the rotating mechanism 3 being rotatably connected to the top of a support turntable 4, the bottom of the support turntable 4 having a support plate 5, a preparation container 6 being snapped into the inner wall of the support plate 5, and a common hopper 7 vertically penetrating the middle of the top of the preparation container 6.

[0029] The bottom end of the rotating mechanism 3 extends vertically through the middle of the top of the support frame 8.

[0030] In this embodiment, as Figure 1 and Figure 3 and Figure 4As shown, the connecting channel 2 includes a main pipe 201, the top of which is located at the bottom of the powder container 1. A feeding pipe 202 is inserted into the outer wall of the main pipe 201 near the common hopper 7. A flow valve 203 is installed on the outer wall of the top of the main pipe 201.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the feed pipe 202 is inclined.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the rotating mechanism 3 includes a handle 301, a rotating shaft 302 at the bottom of the handle 301, the bottom of the rotating shaft 302 vertically penetrating the middle of the top of the support frame 8, a rotating plate 303 inserted into the bottom of the rotating shaft 302, and several rotating rods 304 at the bottom of the rotating plate 303.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the support turntable 4 is provided with a rotating groove 401, and the rotating rod 304 is rotatably connected to the rotating groove 401. The bottom of the support turntable 4 is provided with several supporting feet 402, and the bottom ends of the several supporting feet 402 are located on the top of the support plate 5.

[0034] The working process of this laser cladding powder container powder changing device is as follows:

[0035] When using it for the first time, the operator can first load different types of laser cladding powder raw materials into each powder container 1. The connecting channel 2 at the bottom of the powder container 1 is connected to the structure below through the main pipe 201. The feeding pipe 202 on one side of the main pipe 201 is inclined to facilitate the powder to slide down, while the flow valve 203 (model: E290A) at the top is closed at this time.

[0036] When a certain powder is needed, the operator can first manually turn the handle 301 in the rotating mechanism 3 to start the rotating shaft 302 at its bottom to rotate, and drive the rotating plate 303 that is inserted with it to rotate together. At this time, the rotating rod 304 at the bottom of the rotating plate 303 will slide in the rotating groove 401 at the top of the supporting turntable 4, so that the connecting channel 2 at the bottom of the target powder container 1 can be rotated and adjusted until it is aligned with the top opening of the common hopper 7.

[0037] After alignment, the operator can open the flow valve 203 at the top of the main pipe 201 of the connection channel 2, so that the powder in the powder container 1 is conveyed downward through the main pipe 201 to the feeding pipe 202. At this time, the powder will continue to slide down the feeding pipe 202 into the interior of the common hopper 7, and finally enter the preparation container 6 for temporary storage. Then the powder can be conveyed from the preparation container 6 to the laser cladding working area through the subsequent connected pipe.

[0038] If it is necessary to change the type of powder, the operator can first close the flow valve 203 of the current connection channel 2 to stop the powder conveying, and then turn the handle 301 again, and drive the rotating rod 304 to rotate in the rotating groove 401 through the rotating shaft 302 and the rotating plate 303, so that the connection channel 2 of the other powder container 1 rotates until it is aligned with the top opening of the common hopper 7. Repeat the above operation of opening the flow valve 203 and rotating the rotating mechanism 3 to achieve the switching of different powders.

[0039] Throughout the process, the support turntable 4 achieves stable rotation of the rotating mechanism 3 through the rotational connection between the rotating groove 401 and the rotating rod 304. The support frame 8 fixes the rotating shaft 302 to ensure that the rotating mechanism 3 runs vertically. The support plate 5 and the support foot 402 provide stable support for the entire device.
