[0036] During operation, a metal powder processing storage device in the above-mentioned technology, when the cover is opened to take out the metal powder inside the storage barrel, the outside air will enter the interior of the storage barrel, so when the cover is closed, it is necessary to re-introduce inert gas, resulting in a large consumption of inert gas. Through the structural design of the sealing mechanism, when the storage barrel 32 is taken out, the gap between the sleeve 31 and the positioning ring 60 is sealed to reduce the escape of the inert gas inside the storage barrel main body 1, thereby solving the problem that a metal powder processing storage device in the above-mentioned technology, when the cover is opened to take out the metal powder inside the storage barrel main body, the outside air will enter the interior of the storage barrel main body, so when the cover is closed, it is necessary to re-introduce inert gas, resulting in a large consumption of inert gas. By turning the knob 21 on the right side of the storage barrel main body 1, the first bevel gear 23 and the second bevel gear 24 inside the storage barrel main body 1 can be driven to rotate, and the rotation of the second bevel gear 24 will drive the rotation When the disk 26 rotates, the rotating barrel 28 fixedly connected to the rotating disk 26 will rotate synchronously. A storage groove 29 is provided on the rotating barrel 28, and a sleeve 31 is inserted inside the storage groove 29. In the process of taking the metal raw material in the storage barrel 32, the rack 44 will move upward under the action of the lifting mechanism, thereby driving the fixed frame 68 on the top of the rack 44 to move synchronously. A moving frame 66 is connected to the top of the fixed frame 68. The structural design of the top of the moving frame 66 will make the two groups of semicircular rings 64 gradually approach each other until the two groups of semicircular rings 64 contact each other, and the first spring 63 fixed on the semicircular ring 64 will be compressed. When the two groups of semicircular rings 64 contact each other, the rubber strip 65 fixed on the inner wall of the semicircular ring 64 will abut against the surface of the sleeve 31, thereby ensuring that there is no gap between the sleeve 31 and the positioning ring 60. At this time, when the cover plate 20 is opened, the interior of the storage barrel body 1 will still form a relatively sealed space with the outside world, thereby reducing the escape of the inert gas inside the storage barrel body 1.

[0037] The structural design of the lifting mechanism makes it possible to bring the sleeve 31 inside the storage groove 29 upward when the cover plate 20 is pulled, thereby facilitating the removal of the storage barrel 32 inserted on the sleeve 31, thereby avoiding the need to reach into the storage barrel body 1 by hand. When the cover plate 20 is pulled to open the storage barrel body 1, the fourth gear 54 will rotate clockwise, and the fourth gear 54 will transmit the rotation to the third gear 53, and the third gear 53 will drive the second gear 52 to rotate synchronously through the belt 49. During the rotation, the second gear 52 will drive the first gear 51 to rotate in the opposite direction, so that the rotation direction of the first gear 51 is the same as that of the fourth gear 54. At this time, the rack 44 meshing with the first gear 51 will move upward under the rotation of the first gear 51. A fixing frame 42 is fixed on one side of 44, and a spring block 41 is fixed inside the fixing frame 42. When the rack 44 does not move, the spring block 41 will abut against the inner wall of the cylindrical groove 30. When the rack 44 gradually moves upward, the spring block 41 will be inserted into the slot 40 to complete the engagement. At this time, the rack 44 continues to move upward, and the spring block 41 can drive the sleeve 31 to move together. The first gear 51, the second gear 52, the third gear 53, the fourth gear 54 and the connecting frame 55 are all rotatably connected with the two groups of retaining frames 48.

[0039] During operation, through the structural design of the protrusion 70, when the rotating disk 26 drives the rotating barrel 28 to rotate to the bottom of the cover plate 20, the abutment column 71 can move upward by abutting against the protrusion 70, thereby lifting the sleeve 31 inside the storage groove 29 upward for a distance, so that the top end of the sleeve 31 is aligned with the bottom end of the positioning ring 60.

[0040] Furthermore, a positioning rod 80 is passed through the interior of the moving block 82, the top and bottom ends of the positioning rod 80 are fixedly connected to the inner wall of the long slot 79, and the third spring 81 is sleeved on the outer side of the positioning rod 80;

[0041] During operation, when the sleeve 31 moves, the moving block 82 fixed on the sleeve 31 will slide in the long groove 79 and be reset by the third spring 81 fixed on the bottom end of the moving block 82.

The rotating disk 26 does not contact the inner wall of the storage barrel body 1, and the rotating disk 26 abuts against the sealing ring 75. The snap ring 74 and the sealing ring 75 are both fixedly connected to the inner wall of the storage barrel body 1.

[0043] During operation, when the connecting rod 25 drives the rotating disk 26 to rotate, in order to improve the supporting capacity of the rotating disk 26, a groove 72 is opened on the rotating disk 26. The engagement of the groove 72 with the snap ring 74 ensures that the rotating disk 26 can better support the rotating barrel 28, while also reducing the shaking of the rotating disk 26 during rotation. The rotating disk 26 also abuts against the snap ring 74 to seal the rotating disk 26 and the storage barrel body 1.

[0044] Furthermore, a sealing block 87 is fixedly connected to the inner wall of the rotating groove 57, and the sealing block 87 is made of rubber material;

[0045] During operation, a sealing block 87 is fixed on the rotating groove 57 to improve the sealing performance of the rotating groove 57 so as to reduce the loss of the inert gas inside the storage barrel body 1 .

[0046] Furthermore, a mounting groove 85 is provided on the bottom end of the cover plate 20 and the top end of the storage barrel body 1, and a magnet 84 is fixedly connected inside the mounting groove 85;

[0047] During operation, the cover plate 20 is fixed to the storage barrel body 1 by the mutual attraction between the two groups of magnets 84, and it is also convenient to open the cover plate 20.

[0048] Furthermore, an annular groove 77 is formed in the middle of the rotating barrel 28, and a pulley 78 is fixedly connected to the inner wall of the annular groove 77, and the pulley 78 contacts the inner wall of the storage barrel body 1;

[0049] During operation, an annular groove 77 is opened in the middle of the rotating barrel 28, and four sets of pulleys 78 are fixed on the annular groove 77. During the rotation of the rotating barrel 28, the contact between the pulleys 78 and the inner wall of the storage barrel body 1 is used to improve the stability of the rotating barrel 28 and reduce the shaking of the rotating barrel 28.

[0050] Furthermore, the left side of the knob 21 contacts the fixing ring 73, and the fixing ring 73 is fixedly connected to the storage barrel body 1, and scales are provided on both the knob 21 and the fixing ring 73;

[0051] During operation, scales are provided on the knob 21 and the fixing ring 73 so that during the rotation of the knob 21 , the rotation angle can be accurately controlled by penetrating the knob 21 and the fixing ring 73 so that the top end of the sleeve 31 can be aligned with the bottom end of the positioning ring 60 .

[0052] Working principle: A storage device for metal powder processing in the prior art, when the cover is opened to take out the metal powder inside the storage barrel main body, the outside air will enter the interior of the storage barrel main body, so when the cover is closed, it is necessary to re-introduce inert gas, resulting in a large consumption of inert gas. A metal raw material storage device in this case uses the structural design of the sealing mechanism to achieve sealing of the gap between the sleeve 31 and the positioning ring 60 when the storage barrel 32 is taken out, so as to reduce the escape of the inert gas inside the storage barrel main body 1, thereby solving the problem of a storage device for metal powder processing in the above-mentioned technology, when the cover is opened to take out the metal powder inside the storage barrel main body, the outside air will enter the interior of the storage barrel main body, so when the cover is closed, it is necessary to re-introduce inert gas, resulting in a large consumption of inert gas. By turning the knob 21 on the right side of the storage barrel main body 1, the first bevel gear 23 and the second bevel gear 24 inside the storage barrel main body 1 can be driven to rotate, and the second bevel gear The rotation of the wheel 24 will drive the rotating disk 26 to rotate, and at this time, the rotating barrel 28 fixedly connected to the rotating disk 26 will rotate synchronously. The rotating barrel 28 is provided with a storage groove 29, and a sleeve 31 is inserted in the storage groove 29. In the process of taking the metal raw materials in the storage barrel 32, the rack 44 will move upward under the action of the lifting mechanism, thereby driving the fixed frame 68 on the top of the rack 44 to move differently. The top of the fixed frame 68 is connected to the mobile frame 66, and the structural design of the top of the mobile frame 66 The two groups of semicircular rings 64 will gradually approach each other until they contact each other, and the first spring 63 fixed on the semicircular rings 64 will be compressed. When the two groups of semicircular rings 64 contact each other, the rubber strip 65 fixed on the inner wall of the semicircular ring 64 will abut against the surface of the sleeve 31, thereby ensuring that there is no gap between the sleeve 31 and the positioning ring 60. At this time, when the cover 20 is opened, the interior of the storage barrel body 1 will still form a relatively sealed space with the outside world, thereby reducing the escape of inert gas inside the storage barrel body 1.

[0053] The structural design of the lifting mechanism makes it possible to bring the sleeve 31 inside the storage groove 29 upward when the cover plate 20 is pulled, thereby facilitating the removal of the storage barrel 32 inserted on the sleeve 31, thereby avoiding the need to reach into the storage barrel body 1 by hand. When the cover plate 20 is pulled to open the storage barrel body 1, the fourth gear 54 will rotate clockwise, and the fourth gear 54 will transmit the rotation to the third gear 53, and the third gear 53 will drive the second gear 52 to rotate synchronously through the belt 49. During the rotation, the second gear 52 will drive the first gear 51 to rotate in the opposite direction, so that the rotation direction of the first gear 51 is the same as that of the fourth gear 54. At this time, the rack 44 meshing with the first gear 51 will move upward under the rotation of the first gear 51. A fixing frame 42 is fixed on one side of 44, and a spring block 41 is fixed inside the fixing frame 42. When the rack 44 does not move, the spring block 41 will abut against the inner wall of the cylindrical groove 30. When the rack 44 gradually moves upward, the spring block 41 will be inserted into the slot 40 to complete the engagement. At this time, the rack 44 continues to move upward, and the spring block 41 can drive the sleeve 31 to move together. The first gear 51, the second gear 52, the third gear 53, the fourth gear 54 and the connecting frame 55 are all rotatably connected with the two groups of retaining frames 48.
