[0002] Metal powders, as an indispensable basic raw material in modern industry, are widely used in additive manufacturing (3D printing), powder metallurgy, injection molding, welding materials, catalysts, and aerospace. During their production, transportation, and storage, they typically require sealed packaging in bags made of specific materials to prevent oxidation, moisture absorption, and ensure accuracy during use.
[0003] The existing sealing method involves filling a packaging bag with metal powder, then placing the bag on a sealing and cutting device for sealing and cutting. Each time metal powder is filled, a packaging bag with one end sealed and the other open is required, making it difficult to achieve continuous bagging, sealing, and cutting operations. Utility Model Content

[0005] To achieve this technical objective, the present invention adopts the following solution: a sealing and cutting device for metal powder packaging, comprising a support frame, a pressing mechanism, a sealing mechanism, and a cutting mechanism; The middle of the support frame has a working area for holding packaging bags; The clamping mechanism is located at the top of the working area and is used to clamp the opening of the packaging bag; The sealing mechanism is mounted on the support frame and is used to seal the packaging bag; The cutting mechanism is mounted on the support frame and is used to cut the sealing area of the packaging bag.
[0006] Furthermore, the sealing mechanism includes a first electric actuator, a guide rod, a connecting block, a heating rod, and a heat sealing head; The first electric actuator is fixed on the side wall of the support frame, and the movable end of the first electric actuator can slide through the support frame and extend into the working area. The connecting block is fixedly connected to the movable end of the first electric actuator; The guide rod is fixedly connected to the connecting block, and the guide rod is slidably inserted into the support frame; The heating rod is inserted into the connecting block; The heat seal head is fixed on the side of the connecting block away from the first electric push rod, and a gap is left between the two heat seal heads.
[0007] Furthermore, the clamping mechanism includes a connecting plate, a pressure block, a spring, a top plate, and a suction pipe; The two connecting plates are symmetrically distributed and are fixed at the upper and lower ends of the connecting block, respectively; One side of the pressure block is fixed with multiple insert rods arranged in a linear array.

[0008] Furthermore, the cutting mechanism includes a second electric actuator and a blade; The second electric actuator is fixed on the support frame; The cutter head is fixedly connected to the movable end of the second electric actuator; The blade can pass through the gap and enter the cavity.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a sealing and cutting device for metal powder packaging, which is suitable for continuous bagging, sealing and cutting operations. It is used to seal and cut extra-long packaging bags step by step.

[0012] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.
[0013] like Figures 1-3 As shown, this utility model discloses a sealing and cutting device for metal powder packaging, including a support frame 1, a pressing mechanism 2, a sealing mechanism 3 and a cutting mechanism 4; The middle of the support frame 1 has a working area 11 for holding the packaging bags 5; The pressing mechanism 2 is located at the top of the working area 11 and is used to press the opening of the packaging bag 5; The sealing mechanism 3 is mounted on the support frame 1 and is used to seal the packaging bag 5. The cutting mechanism 4 is mounted on the support frame 1 and is used to cut the sealing area of the packaging bag 5.
[0014] Furthermore, the sealing mechanism 3 includes a first electric push rod 31, a guide rod 32, a connecting block 33, a heating rod 34, and a heat sealing head 35; The first electric actuator 31 is fixed on the side wall of the support frame 1, and the movable end of the first electric actuator 31 can slide through the support frame 1 and extend into the working area 11. The connecting block 33 is fixedly connected to the movable end of the first electric push rod 31; The guide rod 32 is fixedly connected to the connecting block 33, and the guide rod 32 is slidably inserted into the support frame 1; The heating rod 34 is inserted into the connecting block 33; The heat seal head 35 is fixed on the side of the connecting block 33 away from the first electric push rod 31, and a gap 36 is left between the two heat seal heads 35.
[0015] Furthermore, the clamping mechanism 2 includes a connecting plate 21, a pressure block 22, a spring 23, a top plate 24, and an air intake pipe 25; The two connecting plates 21 are symmetrically distributed and are fixed at the upper and lower ends of the connecting block 33, respectively; A plurality of rods 221 arranged in a linear array are fixed on one side of the pressure block 22. The rods 221 are slidably inserted into the connecting plate 21. A limiting ring 222 is fixed at the end of the rod 221 away from the pressure block 22. The limiting ring 222 abuts against the connecting plate 21. Spring 23 is sleeved on insert rod 221, and the two ends of spring 23 abut against connecting plate 21 and pressure block 22 respectively; The two top plates 24 are arranged symmetrically, with a gap 26 between them. Multiple screws 241 are fixed on one side of the top plate 24, and the screws 241 are fixed to the support frame 1 by nuts. One end of the air intake pipe 25 is inserted into the top plate 24, and the other end is connected to the air intake mechanism. The air intake mechanism can be existing technologies such as a fan, and this application does not impose any restrictions.
[0016] Furthermore, the cutting mechanism 4 includes a second electric push rod 41 and a cutter head 42; The second electric actuator 41 is fixed on the support frame 1; The cutter head 42 is fixedly connected to the movable end of the second electric actuator 41; The blade 42 can pass through the gap 26 and enter into the gap 36.
[0017] In use, a packaging bag 5, sealed at one end and open at the other, with a certain length, is placed in the working area 11. The suction mechanism connected to the suction pipe 25 is activated, creating negative pressure inside the suction pipe 25. This causes one side of the packaging bag 5 to adhere to the top plate 24, preventing the packaging bag 5 from moving during the filling process. Metal powder is then filled into the packaging bag 5. After filling to the predetermined amount, the first electric actuator 31 is activated. The first electric actuator 31 moves the connecting block 33 closer to the packaging bag 5, further moving the heat sealing head 35 and the pressure block 22 closer to the packaging bag 5. The pressure block 22 first contacts the packaging bag 5, pressing it tightly against the top plate 24. The first electric actuator 31 extends further, the spring 23 contracts, and the insertion rod 221 slides on the connecting plate 21. The heat sealing head 35 moves closer to the packaging bag 5 until it contacts and heat-seals it. Because there is a gap 36 between the two heat sealing heads 35, two spaced sealing areas are formed on the packaging bag 5.
[0018] The second electric actuator 41 is activated, bringing the cutter head 42 close to the packaging bag 5 and cutting it into two sections. The lower packaging bag 5 has both its top and bottom openings sealed, while the bottom opening of the upper packaging bag 5 is sealed, allowing for further filling. The upper packaging bag 5 then unwinds and descends under the weight of the material. Repeating this process completes the continuous sealing and cutting operations.
[0019] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
