Description

Technical Field

[0001] This utility model relates to the technical field of mixing mechanisms, specifically a dry mixing mechanism for metal powder. Background Technology

[0002] A dry mixing mechanism for metal powders refers to equipment specifically designed for the dry mixing of metal powders. After the raw materials enter the mixing chamber, they are thoroughly mixed by a specially designed agitator. The agitator speed and mixing time can be adjusted according to different raw materials and mixing requirements to ensure the uniformity and consistency of the mixing effect.

[0003] Existing dry mixing mechanisms are typically single-function and use a single mixing method. In actual operation, when mixing various types of metal powders, stratification is prone to occur, meaning that the bottom layer of metal powder cannot reach the top layer, resulting in poor mixing effect. Finally, during the discharge process after mixing, the different metal powders are unevenly distributed, reducing the subsequent parts processing effect. To address the shortcomings of the existing technology, this utility model provides a dry mixing mechanism for metal powders to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides a dry mixing mechanism for metal powders, which solves the problem that existing dry mixing mechanisms are usually single in function and mixing method, and that in actual operation, many different types of metal powders are prone to stratification when being mixed.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses a dry mixing mechanism for metal powder, according to the attached... Figure 1-5 As shown, the device includes a mixing tank 1, a stirring rod 2 inside the mixing tank 1, and a drive unit 3 corresponding to the stirring rod 2 at the bottom of the mixing tank 1. The device uses the drive unit 3 to drive the stirring rod 2 to rotate, thereby using the rotation of the stirring rod 2 to dry mix the metal powder raw materials added inside the mixing tank 1.

[0027] The drive unit 3 includes a motor bracket 31 fixedly connected to the bottom of the mixing tank 1 and a first motor 32 fixedly connected to the motor bracket 31. The output end of the first motor 32 is connected to the stirring rod 2. The drive unit 3 has a simple structure. The drive unit 3 uses the motor bracket 31 to support the first motor 32, and the first motor 32 provides power to the stirring rod 2.

[0028] A discharge hopper 13 is fixedly connected to the mixing tank 1, a top cover 14 is snapped onto the top of the mixing tank 1, and a support leg 15 is fixedly connected to the bottom of the mixing tank 1. The device facilitates material discharge through the design of the discharge hopper 13. After the metal powder is mixed, it is discharged. The support leg 15 design makes the entire device stable.

[0029] The mixing tank 1 has a secondary material pipe 4 on its side, and a lifting unit 5 on the secondary material pipe 4. The lifting unit 5 includes a second motor 51 fixedly connected to the secondary material pipe 4 and a screw rod 52 fixedly connected to the output end of the second motor 51. The screw rod 52 is rotatably connected inside the secondary material pipe 4. The mixing tank 1 has a bottom material trough 11 and a top material trough 12 that are connected to the secondary material pipe 4.

[0030] The device, through the design of the auxiliary material pipe 4 and the lifting unit 5, facilitates the rapid lifting of the bottom layer of metal powder to the upper layer for mixing during the mixing process, avoiding the phenomenon of metal powder stratification and uneven mixing. The lifting unit 5 has a simple structure and is powered by the second motor 51. When the second motor 51 is working, it drives the screw rod 52 to move, and the screw rod 52 realizes the transportation of powder inside the auxiliary material pipe 4 from the lower to the higher position.

[0031] When the drive unit 3 drives the stirring rod 2 to move, the metal powder inside the mixing tank 1 is continuously rotated and stirred horizontally. Under the action of centrifugal force, the bottom metal powder will continuously enter the bottom material tank 11 and the auxiliary material pipe 4. The lifting unit 5 will then lift the metal powder inside the auxiliary material pipe 4 and finally discharge it from the top material tank 12 into the upper layer of the mixing tank 1, so that the upper and lower layers of metal powder are continuously mixed and the mixing effect is good.

[0032] The auxiliary material pipe 4 is equipped with a sealing seat 6, and a sealing door 61 is movably engaged inside the sealing seat 6. Through the design of the sealing seat 6 and the sealing door 61, this device facilitates the opening and closing of the channel of the bottom material trough 11. When the channel of the bottom material trough 11 is closed, the function of the mixing tank 1 is the same as that of the prior art, realizing simple mixing and stirring. When the channel of the bottom material trough 11 is opened, the mixing tank 1, in conjunction with the design of the auxiliary material pipe 4 and the lifting unit 5, can quickly realize the vertical mixing of the upper and lower layers of materials during the horizontal stirring process. Therefore, the mixing tank 1 can be set according to actual needs.

[0033] The sealing seat 6 is provided with an adjustment mechanism 7 for shifting the sealing door 61. The adjustment mechanism 7 includes a screw 72 threadedly connected to the sealing seat 6 and a slider 71 fixedly connected to the sealing door 61. The slider 71 is slidably connected inside the sealing seat 6, and a rotating handle 721 is fixedly connected to the screw 72.

[0034] The dry mixing mechanism for metal powder is designed with an adjustment mechanism 7, which makes it easy to adjust the position of the sealing door 61. During adjustment, the handle 721 can be rotated directly. Rotating the handle 721 drives the lead screw 72 to rotate, the lead screw 72 drives the slider 71 to move, and the slider 71 drives the sealing door 61 to move.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
