Description

Technical Field

[0001] The utility model relates to the technical field of metal powder production, and more specifically, to a full-automatic metal powder rough grinding machine. Background Art

[0002] In the process of preparing metal powder, various metal raw materials or non-metallic auxiliary materials need to be crushed by physical means, and then prepared. This method is suitable for metal materials or most non-metallic materials that are inconvenient to be crushed by impact at high temperature after heating. This is the most commonly used method in the preparation of metal powder.

[0003] However, in the existing physical preparation methods of metal powders, it is easy for large pieces of material to be mixed with a considerable amount of non-uniform powders into the grinding process, resulting in uneven sizes of the obtained crushed materials, which affects subsequent use and processes. At the same time, the nature of large pieces of material makes it difficult to control the amount of feed, and the large difference in feed amount is also one of the factors that lead to uneven powder grinding. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fully automatic metal powder rough grinding machine to solve one or more of the above-mentioned problems.

DETAILED DESCRIPTION

[0033] Example:

[0034] The following is combined with Figure 1-5 The utility model is described in further detail.

[0035] Fully automatic metal powder grinding machine, such as Figure 1 As shown, it is divided into three parts according to the direction of material transportation: right, middle and left. The rightmost part is the material storage bin 10, the middle part is the feeding mechanism 20, the feeding mechanism 20 has a shaking mechanism 30, and the leftmost part is the grinding mechanism 40.

[0036] like Figure 5 As shown, the stacking bin 10 is a funnel-shaped storage bin structure with corners at the side junction and a horizontal bottom. A notch is provided on the lowermost slope of the left side, and the notch is butted against the feeding mechanism 20, that is, the width of the notch is not greater than the width of the feeding mechanism 20. The notch needs to be butted against the slope of the feeding mechanism 20 to prevent the block materials from falling during transportation. In order to ensure the tendency of the materials to roll down, the slope of the right side of the stacking bin 10 is designed to be smaller than that of the left side, so that the materials will automatically roll toward the notch on the left side.

[0037] like Figure 3As shown, the main body of the feeding mechanism 20 is a normal feeding machine, and the top and bottom ends are transmitted by the feeding belt 21. The feeding belt 21 is a ring-shaped closed loop conveyor belt as a whole, and a number of isolation plates 22 are evenly distributed on the outer side of the feeding belt 21. The isolation plates 22 ensure that the materials taken out from the stacking bin 10 during the operation of the conveyor belt are limited and uniform. The bottom end is connected to the stacking bin 10, that is, the lower end of the feeding belt 21 is aligned with the notch of the stacking bin 10, and the top is provided with a corner pipe 23 to guide the material to fall into the grinding mechanism 40. One end of the corner pipe 23 covers the top of the feeding mechanism 20, that is, covers the top frame and the feeding belt 21 to prevent the material from falling during the turning process. The other end of the corner pipe 23 hangs down above the grinding mechanism 40. The feeding belt 21 is composed of a plurality of connected plates, each of which has two symmetrical through slots, which are staggered with the docking holes required for the plate combination, that is, two separate through slots are opened without affecting the connection structure of the feeding belt 21. The diameter of the through slots needs to filter out the powder on the block material, but unlike the sieve, the holes can be larger, even if some small pieces of material are filtered out. A powder recovery box is provided under the frame of the feeding mechanism 20, or a detachable powder bag is directly wrapped under the frame to recover the sieved powder and small block materials and prevent dust from flying.

[0038] like Figure 4 As shown, inside the feeding mechanism 20, that is, on the back of the feeding belt 21, there is a shaking mechanism 30 that does not affect the normal transmission of the feeding belt 21. The shaking mechanism 30 includes a plurality of shaking heads 31 and a shaking motor 32 evenly distributed along the feeding belt 21. The shaking motor 32 is arranged inside the feeding belt 21, and the movable end of the shaking motor 32 is fixedly connected to the shaking head 31. The shaking motor 32 is generally a three-phase asynchronous motor, which can drive the shaking head 31 to extend and retract at a high frequency. The setting of the feeding belt 21 must be within the extension range of the shaking head 31, so that the shaking motor 32 can regularly drive the shaking head 31 to knock on the feeding belt 21 to help separate the powder and the block.

[0039] like Figure 2 As shown, the main body of the grinding mechanism 40 is a grinding chamber 41. The grinding chamber 41 is a hollow structure without a top, with grinding lines inside (not marked in the figure), and a discharge port is opened on the bottom side. The discharge port must be staggered from the grinding cavity, that is, the discharge port can only discharge the ground material. Two coaxially arranged grinding turntables 42 with different diameters are arranged in the grinding chamber 41. The edges also have grinding lines. The number of teeth of the grinding lines on the edges of different grinding turntables 42 is different, otherwise it will affect the grinding accuracy. In order to allow the grinding turntables 42 to rotate, a grinding motor 43 is arranged at the bottom of the grinding chamber 41. The grinding motor 43 passes through the bottom of the grinding chamber 41 and is connected to the two grinding turntables 42 to drive them to rotate. A transmission unit 44 is arranged at the discharge port, and the transmission unit 44 is a conventional belt conveyor.

[0040] The original material is put into the stacking bin 10, piled up at the bottom of the stacking bin 10 and guided to the left notch, and roughly equal amounts of materials are separated in batches by the isolation plate 22 and transported through the feeding belt 21. At the same time, under the action of the shaking unit, the adhered powder and scattered small pieces of material fall into the collecting component from the through groove of the feeding belt 21, and the large pieces of material continue to be guided into the grinding bin 41 through the corner pipe 23. With the cooperation of the two grinding turntables 42 and the inner wall of the grinding bin 41, they are graded and crushed, fall from the discharge port to the transmission unit 44 and are transmitted downward.

[0041] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
