Description

Technical Field

[0001] This utility model relates to the field of metallurgical mixing technology, specifically a powder metallurgy mixing machine. Background Technology

[0002] Powder metallurgy mixing is the process of mixing metal powders, additives such as lubricants, binders, and alloy element powders according to a formula ratio to form a mixed powder with uniform composition and consistent performance. It is one of the core links in the powder metallurgy process that determines the performance of the final product. The core objective of mixing is to break the initial distribution state of powder particles through mechanical force or flow field action, so that particles of different compositions and particle sizes are uniformly dispersed at both the macroscopic and microscopic scales.

[0003] The powder metallurgy raw material mixing equipment authorized by announcement number CN216756292U includes a mixing barrel with a telescopic component installed on the upper side of the mixing barrel. A first stirring shaft is rotatably fitted inside the mixing barrel, and a transmission rod is installed on the upper side of the first stirring shaft. A second stirring shaft is sleeved around the transmission rod. An L-shaped plate is connected to the bottom surface of the telescopic component. A first motor drives the gears on both ends to rotate in opposite directions, which in turn drives the first stirring shaft and the second stirring shaft to rotate in opposite directions. This causes the raw materials in the upper part of the mixing barrel driven by the second stirring shaft and the raw materials in the lower part of the mixing barrel driven by the first stirring shaft to mix in the middle of the mixing barrel. In existing powder metallurgy raw material mixing equipment, the raw materials are usually added at once. However, the one-time addition of additives can easily lead to excessively high local concentrations, forming agglomeration nuclei, resulting in poor mixing effect.

[0004] To address the aforementioned issues, a powder metallurgy mixing machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a powder metallurgy mixing machine, which solves the problem in the existing powder metallurgy raw material mixing equipment in the background art, where the raw materials are usually added at once, but the one-time addition of additives can easily lead to excessively high local concentrations, forming agglomeration cores, resulting in poor mixing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder metallurgy mixing machine, comprising a mixing mechanism, a storage mechanism fixedly disposed on one side of the upper end of the mixing mechanism, and a feeding mechanism for discharging material between the storage mechanism and the mixing mechanism. The mixing mechanism includes a material cylinder, a fixed frame fixedly disposed at the lower end of the material cylinder, the storage mechanism including a rectangular tank fixedly disposed on the upper end of the fixed frame, a triangular tank fixedly disposed at the lower end of the rectangular tank, a material dispersing component for preventing powder agglomeration rotatably disposed inside the triangular tank, and a spiral conveying paddle rotatably disposed at the lower end of the material dispersing component for discharging powder. The output end of the spiral conveying paddle is connected to a T-shaped tube, the T-shaped tube being connected to the upper end of the material cylinder. Three sets of the storage mechanism and the feeding mechanism are arranged side by side.

[0007] Preferably, a mixing motor is fixedly installed on one side of the material cylinder, the output end of the mixing motor is connected to a rotating shaft, and an annular paddle is fixedly installed on the outer end of the rotating shaft.

[0008] Preferably, the mixing mechanism further includes a side door disposed on one side of the material cylinder, the side door including a flap that is rotatably connected to the material cylinder, and three sets of quick clamps fixedly disposed on one side of the material cylinder, the quick clamps being used to pressurize and fix the flap.

[0009] Preferably, the mixing mechanism further includes a feeding pipe fixedly disposed at the lower end of the material cylinder, a insert rod is movably inserted into the feeding pipe, one end of the insert rod is rotatably connected to a hand crank, one end of the hand crank is rotatably connected to a positioning rod, and the positioning rod is rotatably connected to the feeding pipe.

[0010] Preferably, a quantitative observation window is provided on one side of the rectangular tank.

[0011] Preferably, the material storage mechanism further includes a support member fixedly disposed at the upper end of the material cylinder.

[0012] Preferably, the bulk material assembly includes a bulk material motor fixedly connected to the upper end of the support member, the output end of the bulk material motor is connected to a paddle, and one end of the paddle is connected to a drive wheel.

[0013] Preferably, the feeding mechanism further includes a driven wheel that meshes with the driving wheel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides a powder metallurgy mixer. The material storage mechanism is arranged side by side on the mixing mechanism. Three rectangular tanks are set up to store three different raw materials. The powder is fed and transported by rotating screw conveyors. The three sets of screw conveyors are independently controlled and can add raw materials in batches to improve the mixing effect. At the same time, the horizontal arrangement of the material cylinder and the horizontal distribution of the internal space result in a single processing capacity that is much higher than that of small vertical mixing equipment. The powder mixed inside the material cylinder is carried to a certain height and then falls freely under the action of gravity, forming a composite motion of "throwing-convection-shearing", reducing local accumulation and solving the problem of poor mixing effect of existing powder metallurgy raw material mixing equipment.

[0016] 2. The powder metallurgy mixer provided by this utility model, through the corresponding upper and lower arrangement of the bulk material component and the screw conveyor, allows the powder inside the rectangular and triangular tanks to be dispersed and then conveyed by the rotating screw conveyor, preventing the powder from agglomerating and affecting the subsequent mixing effect. This solves the problem that existing powder metallurgy raw material mixing equipment is prone to local high concentration and agglomeration core formation when added at one time.

Detailed Implementation

[0025] 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 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.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0027] Combination Figure 1This utility model discloses a powder metallurgy mixing machine, including a mixing mechanism 1, a storage mechanism 2 fixedly installed on one side of the upper end of the mixing mechanism 1, and a feeding mechanism 3 for feeding material between the storage mechanism 2 and the mixing mechanism 1. The mixing mechanism 1 includes a material cylinder 11, and a fixed frame 15 fixedly installed at the lower end of the material cylinder 11. The storage mechanism 2 includes a rectangular tank 21 fixedly installed on the upper end of the fixed frame 15, and a triangular tank 22 fixedly installed at the lower end of the rectangular tank 21. A material dispersing component 23 for preventing powder agglomeration is rotatably installed inside the triangular tank 22. The feeding mechanism 3 includes a spiral conveyor 32 rotatably installed at the lower end of the material dispersing component 23 for feeding powder. The output end of the spiral conveyor 32 is connected to a T-shaped pipe 33, which is connected to the upper end of the material cylinder 11. Three sets of storage mechanisms 2 and feeding mechanisms 3 are arranged side by side.

[0028] Specifically, the material cylinder 11 enables centralized mixing of raw materials, and the fixing frame 15 supports the material cylinder 11 and the rectangular tank 21. The rectangular tank 21 has three sets, which can store three different raw materials. The triangular arrangement of the triangular tank 22 allows the raw materials inside the rectangular tank 21 to be concentrated towards the screw conveyor 32. At the same time, the rotation of the material dispersing component 23 disperses the powder inside the rectangular tank 21 and the triangular tank 22, preventing the powder from clumping together and affecting the subsequent mixing effect. The rotation of the screw conveyor 32 enables the feeding and conveying of the powder. The three sets of screw conveyors 32 arranged side by side are independently controlled, allowing raw materials to be added in batches to improve the mixing effect. The horizontal arrangement of the material cylinder 11 and the horizontal distribution of its internal space result in a single processing capacity that is much higher than that of small vertical mixing equipment. Moreover, the powder mixed inside the material cylinder 11 is carried to a certain height and then falls freely under the action of gravity, forming a composite motion of "throwing-convection-shearing" to reduce local accumulation.

[0029] The present invention will be further described below with reference to the embodiments.

[0031] Combination Figures 2-5 A mixing motor 12 is fixedly installed on one side of the material cylinder 11. The output end of the mixing motor 12 is connected to a rotating shaft 121. An annular paddle 122 is fixedly installed on the outer end of the rotating shaft 121. The mixing motor 12 drives the rotating shaft 121 to rotate, and the rotating shaft 121 drives the annular paddle 122 to rotate, so that the powder inside the material cylinder 11 is continuously turned over to complete the mixing.

[0032] The mixing mechanism 1 also includes a side door 13 located on one side of the material cylinder 11. The side door 13 includes a flap 131 rotatably connected to the material cylinder 11. Three sets of quick clamps 132 are fixedly installed on one side of the material cylinder 11. The quick clamps 132 are used to pressurize and fix the flap 131. The quick clamps 132 ensure stable clamping force through the dead point principle, resist vibration and impact, and realize the quick clamping and releasing of the flap 131.

[0033] The mixing mechanism 1 also includes a feeding pipe 14 fixedly installed at the lower end of the material cylinder 11. A insert rod 141 is movably inserted into the inside of the feeding pipe 14. One end of the insert rod 141 is rotatably connected to a hand crank 142. One end of the hand crank 142 is rotatably connected to a positioning rod 143. The positioning rod 143 is rotatably connected to the feeding pipe 14. By manually adjusting the hand crank 142, the positioning rod 143 can be rotated, and at the same time, the insert rod 141 can be moved horizontally within the feeding pipe 14 to achieve feeding control.

[0034] Example 2:

[0035] Combination Figures 5-7 A quantitative observation window 211 is provided on one side of the rectangular tank 21. The quantitative observation window 211 is used to observe the raw material inventory.

[0036] The material storage mechanism 2 also includes a support member 24 fixedly installed at the upper end of the material cylinder 11. The support member 24 is connected to the upper end of the material cylinder 11 and is used to support and fix the bulk material motor 231.

[0037] The bulk material assembly 23 includes a bulk material motor 231 fixedly connected to the upper end of the support member 24. The output end of the bulk material motor 231 is connected to a paddle 232. One end of the paddle 232 is connected to a drive wheel 233. Multiple bulk material motors 231 are controlled by a PLC. The bulk material motors 231 are controlled by high-speed pulses, thereby precisely controlling the rotation angle and speed of the bulk material motors 231. The paddle 232 disperses the raw materials. The drive wheel 233 works with the feeding mechanism 3 to drive the raw materials to feed.

[0038] The feeding mechanism 3 also includes a driven wheel 31 that meshes with the driving wheel 233. The driven wheel 31 drives the spiral conveyor 32 to rotate and feed material into the T-shaped tube 33. The T-shaped tube 33 is connected to the material cylinder 11 vertically.
