[0001] The invention relates to the technical field of powder packaging, and in particular to a metal powder packaging device. Background Art

[0002] Powder packaging machine is a device used to automatically divide and package powder materials. This type of equipment usually includes functions such as material conveying, metering, ton bag making, sealing, and coding. It can realize the automatic packaging of powder materials, improve production efficiency, and ensure product quality and packaging accuracy. Powder packaging machines are widely used in food, chemical, pharmaceutical, pesticide and other industries, and are one of the indispensable and important equipment in modern production lines.

[0003] For example, the publication number is CN219029828U, and the subject name is a magnesium powder packaging device. The motor hoist moves along the slideway to lift the containing tube filled with magnesium powder onto the drop rack. A conical drop hopper is arranged in the middle of the platform plate, and a drop pipe is connected to the discharge port of the conical drop hopper. The operator hangs the ton bag on the hook, and the solenoid valve is opened to let the magnesium powder drop into the ton bag through the drop pipe, and then the ton bag is sealed to realize the packaging of the magnesium powder.

[0004] Regarding the above-mentioned related technologies, when magnesium powder falls into the ton bag, the ton bag is hung on the hook, and the opening of the ton bag is in an open state. When the ton bag has collected the magnesium powder, the ton bag is sealed. Since magnesium powder is an active metal powder, it is flammable and oxidizable, so it can react with oxygen at room temperature to generate magnesium oxide. Therefore, the magnesium powder in the ton bag will be oxidized when it comes into contact with the air, so that the magnesium powder will be oxidized and deteriorated while being packaged, which has a negative impact on the quality of the magnesium powder product. Summary of the invention

[0005] In view of this, the present invention provides a metal powder packaging device, aiming to solve the problem of magnesium powder being oxidized and deteriorated while being packaged.

[0006] In order to solve the above technical problems, the present invention provides a metal powder packaging device, including a blanking rack, a blanking hopper and a blanking pipe; a support column, fixedly connected to the blanking rack, the outer wall of the support column is provided with a support ring for sleeved ton bags, and the support column is provided with an exhaust pipe; a support frame, which is slidably arranged on the blanking rack, and a first fastening ring and a second fastening ring are slidably connected to the support frame, and the first fastening ring and the second fastening ring are close to each other to press the ton bag to the support ring; a driving mechanism is arranged on the support frame, and is used to drive the first fastening ring and the second fastening ring to move along the length direction of the support frame; a sealing mechanism is arranged at the bottom of the support frame, and is used to seal the ton bag after the ton bag has collected the powder.

[0007] By adopting the above technical solution, the first fastening ring and the second fastening ring press the opening of the ton bag against the support column before the ton bag collects magnesium powder, thereby reducing the amount of magnesium powder in the ton bag that is exposed to air and the amount of oxidation and deterioration of the magnesium powder when it is packaged, which is beneficial to maintaining the quality of the magnesium powder product.

[0009] By adopting the above technical solution, the movement of the first fastening ring and the second fastening ring is synchronized, and the reciprocating stroke of the first fastening ring and the second fastening ring is constant, which is conducive to the orderly realization of the function of sealing the opening of the ton bag.

[0010] Optionally, the support ring is slidably connected to the support column, and a linear driver that can drive the support frame to slide in a vertical direction is fixedly installed on the blanking rack.

The suction pipe descends and extends into the magnesium powder, vibrates and compacts the magnesium powder, and then extracts the air in the ton bag, which not only improves the packaging effect of the ton bag on the magnesium powder, but also reduces the amount of magnesium powder in the ton bag that flows into the suction pipe when the suction pipe extracts air, thereby reducing the probability of magnesium powder blocking the suction pipe.

[0012] Optionally, a filter screen for filtering powder is fixedly connected to the bottom end of the exhaust pipe.

The bottom end of the exhaust pipe 32 is fixedly connected to a filter screen 321 (refer to Figure 6 ), the filter screen 321 is used to reduce the amount of magnesium powder entering the exhaust pipe 32, thereby reducing the probability of the exhaust pipe 32 being blocked by magnesium powder. An air valve 322 is fixedly installed on the top of the exhaust pipe 32.

[0032] Reference Figure 1 and Figure 2 The outer wall of the connecting rod 14 is slidably sleeved with a support frame 4, and a driving mechanism 5 is provided on the support frame 4.

The bottom wall of the support frame 4 is provided with a sealing mechanism 6, and the sealing mechanism 6 is used to seal the ton bag after the ton bag collects the powder.

[0033] Reference Figure 1 and Figure 2 The outer side wall of the connecting rod 14 is slidably connected with the support frame 4. The driving mechanism 5 includes a first rotation source 51, a driving gear 52, a driven gear 53, a first transmission wheel 54, a first connecting rod 55, a second transmission wheel 56, a second connecting rod 57 and a sliding frame 58. The first rotation source 51 is fixedly mounted on the bottom wall of the support frame 4, the driving gear 52 and the driven gear 53 can mesh with each other, and the driving gear 52 and the driven gear 53 are both rotatably connected to the support frame 4, and the driving shaft of the first rotation source 51 is coaxially fixedly connected with the driving gear 52.

[0034] Reference Figure 1 and Figure 2 The driving gear 52 is coaxially fixedly connected with the first transmission wheel 54, the first connecting rod 55 is hinged with the first transmission wheel 54, and the hinge position of the first connecting rod 55 and the first transmission wheel 54 does not coincide with the center of the first transmission wheel 54, and the end of the first connecting rod 55 away from the first transmission wheel 54 is hinged with the first fastening ring 41. The driven gear 53 is coaxially fixedly connected with the second transmission wheel 56, the second transmission wheel 56 is hinged with the second connecting rod 57, and the hinge position of the second connecting rod 57 and the second transmission wheel 56 does not coincide with the center of the second transmission wheel 56, the end of the second connecting rod 57 away from the second transmission wheel 56 is hinged with the sliding frame 58, and the end of the sliding frame 58 away from the second connecting rod 57 is hinged with the second fastening ring 42.

[0035] Reference Figure 2 The sliding frame 58 is slidably connected to the support frame 4, and the outer wall of the sliding frame 58 is slidably sleeved with a first guide plate 571, and the first guide plate 571 is fixedly connected to the first fastening ring 41, so that the first fastening ring 41 can move along the length direction of the blanking frame 1 under the drive of the first transmission wheel 54, so that the first fastening ring 41 cooperates with the support ring 31 to press the ton bag.

[0036] The operator puts the ton bag on the outer wall of the support column 3, and the first rotation source 51 starts to rotate forward. The first rotation source 51 drives the first transmission wheel 54 to rotate through the driving gear 52. The first transmission wheel 54, the first connecting rod 55 and the first fastening ring 41 form a crank slider structure. The first transmission wheel 54 drives the first fastening ring 41 to move along the length direction of the support frame 4 through the first connecting rod 55. The driving gear 52 drives the driven gear 53 to rotate, and the second transmission wheel 56 rotates synchronously with the driven gear 53. The second transmission wheel 56, the second connecting rod 57 and the sliding frame 58 form a crank slider structure. The second transmission wheel 56 drives the sliding frame 58 to move along the length direction of the support frame 4 through the second connecting rod 57, and the second fastening ring 42 moves synchronously with the sliding frame 58. The first fastening ring 41 and the second fastening ring 42 move closer to each other to press the ton bag against the outer wall of the support ring 31, thereby sealing the opening of the ton bag.

[0037] The control valve 211 opens the drop pipe 21, and the magnesium powder in the drop hopper 2 falls into the ton bag through the drop pipe 21. The top of the exhaust pipe 32 is fixedly connected to an exhaust fan. After the ton bag has collected the magnesium powder, the air valve 322 is opened, and the exhaust fan starts to extract the air in the ton bag. After the air in the ton bag is completely extracted, the first rotation source 51 is reversed to separate the first fastening ring 41 and the second fastening ring 42 from the support ring 31. Finally, the sealing mechanism 6 seals the ton bag to complete the packaging of the magnesium powder.

[0038] The first fastening ring 41 and the second fastening ring 42 press the opening of the ton bag against the support column 3 before the ton bag collects the magnesium powder, reducing the amount of magnesium powder in the ton bag that is exposed to air and the amount of oxidation and deterioration of the magnesium powder when it is packaged, which is beneficial to maintaining the quality of the magnesium powder product.

[0039] In addition, linear drivers 11 are installed on the first fastening ring 41 and the second fastening ring 42 respectively, which can also drive the first fastening ring 41 and the second fastening ring 42 to move along the length direction of the blanking rack 1. However, the driving mechanism 5 of the present invention is used to make the movement of the first fastening ring 41 and the second fastening ring 42 have better synchronization, and the reciprocating stroke of the first fastening ring 41 and the second fastening ring 42 is constant, which is conducive to the orderly realization of the function of sealing the opening of the ton bag.

[0040] Reference Figure 1 , Figure 3 and Figure 4A linear drive 11 is fixedly installed on the blanking rack 1 and can drive the support frame 4 to slide in the vertical direction. The top wall of the blanking rack 1 is rotatably connected to the connecting gear 7. The support ring 31 is fixedly connected to the first rack 71. The outer wall of the exhaust pipe 32 is fixedly connected to the second rack 72. Both the first rack 71 and the second rack 72 can engage with the connecting gear 7. The top of the exhaust pipe 32 is fixedly connected to a support platform 73, and the support platform 73 is fixedly installed with a vibration source 74.

[0041] When the drop pipe 21 transports magnesium powder into the ton bag, the first fastening ring 41 and the second fastening ring 42 cooperate with the support ring 31 to press the ton bag, and after the magnesium powder is collected in the ton bag, the linear drive 11 drives the support frame 4 to move upward, and the first fastening ring 41 and the second fastening ring 42 move upward with the support frame 4. The first fastening ring 41 and the second fastening ring 42 drive the support ring 31 to move upward through friction, and the first rack 71 moves upward with the support ring 31 while driving the connecting gear 7 to rotate, and the connecting gear 7 drives the second rack 72 to move downward, and the exhaust pipe 32 descends with the second rack 72 and extends into the magnesium powder, and the vibration source 74 is started to generate vibration waves, and the vibration waves are transmitted to the magnesium powder through the support platform 73 and the exhaust pipe 32, thereby vibrating and compacting the magnesium powder in the ton bag.

[0042] When the ton bag is placed on the support ring 31, the ton bag will have wrinkles. The first fastening ring 41, the second fastening ring 42 and the support ring 31 drive the opening of the ton bag to move upward, which can tighten the ton bag, which is conducive to the collection of magnesium powder by the ton bag. In addition, the upward movement of the first fastening ring 41, the second fastening ring 42 and the support ring 31 can make the exhaust pipe 32 descend and extend into the magnesium powder, vibrate and compact the magnesium powder, and then extract the air in the ton bag, which not only improves the packaging effect of the ton bag on the magnesium powder, but also reduces the amount of magnesium powder in the ton bag that flows into the exhaust pipe 32 when the exhaust pipe 32 extracts air, thereby reducing the probability of magnesium powder blocking the exhaust pipe 32.

[0043] Reference Figure 3 A limiting ring 33 is fixedly sleeved on the outer wall of the support ring 31 , and the limiting ring 33 can abut against the bottom wall of the support ring 31 , thereby preventing the support ring 31 from falling off the support column 3 due to excessive drop.

[0044] Reference Figure 2 and Figure 5A support shell 61 is fixedly installed on the bottom wall of the first fastening ring 41, and a second rotation source 62 is slidably connected to the side wall of the guide plate. A driving shaft fixed sleeve of the second rotation source 62 is provided with a transmission gear 63. A third rack 64 that can mesh with the transmission gear 63 is fixedly connected inside the support shell 61. The transmission gear 63 is coaxially rotatably connected with a connecting block 65. The connecting block 65 is slidably connected to the support shell 61, and a hot melt rod 66 is fixedly connected to the end of the connecting block 65 away from the transmission gear 63. The hot melt rod 66 is used to seal the opening of the ton bag.

[0045] The second rotation source 62 drives the transmission gear 63 to rotate, thereby causing the transmission gear 63 to move along the length direction of the third rack 64. The transmission gear 63 drives the hot melt rod 66 to move along the length direction of the third rack 64 through the connecting block 65. The hot melt rod 66 seals the opening of the ton bag by melting the ton bag, thereby completing the packaging of the magnesium powder.

[0046] In addition, the ton bag has two sealing methods: button sealing and sewing sealing. Button sealing is the most common sealing method of the ton bag, which is achieved by sewing a few buttons on the bag opening. Sewing sealing is a sealing method achieved by sewing the two sides of the bag opening together with a sewing machine. The present invention uses the hot melt rod 66 to hot melt seal the ton bag, which is suitable for storing small granular items.

[0047] Reference Figure 3 The top wall of the blanking rack 1 is fixedly connected with a second guide plate 8, and the second guide plate 8 is slidably connected to the support platform 73. The second guide plate 8 guides and supports the up and down sliding of the support platform 73, thereby increasing the stability of the movement of the support platform 73.

[0048] The implementation principle of a metal powder packaging device according to an embodiment of the present invention is as follows: the operator puts a ton bag on the outer wall of the support column 3, and the first rotation source 51 starts to rotate forward to drive the first fastening ring 41 to move along the length direction of the support frame 4 through the driving gear 52, the first transmission wheel 54 and the first connecting rod 55. The driving gear 52 drives the second fastening ring 42 to move synchronously with the sliding frame 58 through the driven gear 53, the second transmission wheel 56, the second connecting rod 57 and the sliding frame 58. The first fastening ring 41 and the second fastening ring 42 move closer to each other to press the ton bag against the outer wall of the support ring 31, thereby sealing the opening of the ton bag.

[0049] The control valve 211 opens the drop pipe 21, and the magnesium powder in the drop hopper 2 falls into the ton bag through the drop pipe 21. The top of the exhaust pipe 32 is fixedly connected to an exhaust fan. After the ton bag collects the magnesium powder, the exhaust fan starts to extract the air in the ton bag, and then the first rotation source 51 reverses to separate the first fastening ring 41 and the second fastening ring 42 from the support ring 31. Finally, the hot melt rod 66 seals the ton bag to complete the packaging of the magnesium powder.
