For the packing of powdery materials, such as the packing of products like warm bags, as the materials are powdery materials of metal, the powdery materials can be adsorbed into non-magnetic moulds with different shapes through magnets, then are placed into an upper packing mould and a lower packing mould through a plurality of roller devices, and are thermally bonded together through heating.
In the prior art, the metal powder material is packaged by adopting the shape that magnets are respectively processed into a feeding roller and a heat sealing roller. When the material is transferred between the feeding roller and the heat sealing roller, the magnetic force lines of the feeding roller are shielded by the magnetism isolating sheet, and then the magnet shielding of the heat sealing roller is disconnected, so that the magnetic force lines of the heat sealing roller are opened, and the powdery metal material is adsorbed into the mold corresponding to the heat sealing roller through the magnetic force effect, so that the material is packaged. Of course, another way is to simulate the above packaging method, but the magnet is made into a semi-cylindrical shape, one half is used at the loading position of the feeding roller, and the other half is used for transferring the material from the feeding roller to the heat sealing roller to realize packaging of the material.

It is to be understood that the described embodiments are only some of the embodiments of the present invention and not all the embodiments. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
Example 1:
a metal powder material packaging device, as shown in fig. 1 to 3, comprises a storage box 1, a feeding roller 2, a heat sealing roller 15 and a heating roller 12. The feeding roller 2 is made of 45 # steel into a cylindrical structure, end cover plates 23 are arranged at two ends of the feeding roller 2, a roller central shaft 18 is arranged in the center of each end cover plate 23, and a central bearing 19 is arranged between each roller central shaft 18 and each end cover plate 23 so as to facilitate free rotation of each roller central shaft 18. A roller bearing 22 is also provided between the feed roller 2 and the end cap plate 23 to facilitate free rotation of the feed roller 2.
As shown in fig. 1 to 3, two sets of synchronizing wheels 10 are further provided on the end cover plate 23, and a synchronizing wheel bearing 20 is provided between each set of synchronizing wheels 10 and the end cover plate 23 to facilitate free rotation of the synchronizing wheels 10. A plurality of driving wheels 6 are arranged between the two groups of synchronous wheels 10, so that the synchronous wheels 10, the plurality of driving wheels 6 and the roller central shaft 18 form a fan-shaped structure which takes the roller central shaft 18 as a central angle and the synchronous wheels 10 and the plurality of driving wheels 6 as circular arcs. The synchronous belt 5 is arranged on the fan-shaped structure, and a plurality of magnets 4 are uniformly distributed on the synchronous belt 5, so that the synchronous belt 5 can drive the plurality of magnets 4 to rotate along a closed and fixed fan-shaped path.
As shown in fig. 1 to 3, both ends of the synchronizing wheel 10 and the drum center shaft 18 extend beyond the end cover plates 23 at both ends of the feed roller 2, and both ends of the synchronizing wheel 10 and the drum center shaft 18 are rotatably installed at fixed positions. The two ends of the driving wheels 6 can be arranged on the end cover plate 23 and connected through bearings, and can also penetrate through the end cover plate 23 to be rotatably arranged at a fixed position.
As shown in fig. 1 to 3, an inner gear ring 8 positioned on the inner side wall of the feed roller 2 is arranged on the outer side of one side end cover plate 23 of the feed roller 2, a gear 9 is fixedly connected to the synchronous wheel 10, and the inner gear ring 8 is in meshed connection with the gear 9, so that the feed roller 2 and the synchronous belt 5 can synchronously rotate. Meanwhile, an outer gear ring 21 positioned on the outer side wall of the feed roller 2 is arranged on the outer side of the end cover plate 23 on the corresponding side of the feed roller 2, and the outer gear ring 21 is connected with power equipment through a gear set, so that the power equipment can drive the feed roller 2 to rotate through the meshing of the gear set and the outer gear ring 21.
As shown in fig. 1 to 3, the heat-seal roller 15 has the same structure as the above-described feed roller 2, and the heat-seal roller 15 is tangent to the feed roller 2. Only the timing belt 5 of the fan-shaped path of the heat-seal roller 15 and the timing belt 5 of the fan-shaped path of the feed roller 2 are offset from each other at the tangential point positions, so that the magnetic field lines of the heat-seal roller 15 and the feed roller 2 are offset from each other at the tangential point positions.
As shown in fig. 1 to 3, the storage tank 1 is disposed on top of the feed roller 2, and the heat sealing roller 15 is also tangent to the heating roller 12. Wherein, the magnetic field line of the feed roller 2 covers between the bottom of the discharge hole of the storage box 1 and the tangent points of the heat sealing roller 15 and the feed roller 2, and the magnetic field line of the heat sealing roller 15 covers between the tangent points of the heat sealing roller 15 and the feed roller 2 and the tangent points of the heat sealing roller 15 and the heating roller 12.

The heat sealing roller 15 is driven by the power equipment to synchronously rotate in opposite directions with the feeding roller 2, and drives the upper packaging film 16 to cover the heat sealing roller 15 to rotate together. When the feeding roller 2 transfers the metal powder material to the position of the tangent point with the heat-seal roller 15, the magnetic field lines of the feeding roller 2 are disengaged, and at the same time, the magnetic field lines of the heat-seal roller 15 intervene, so that the metal powder material on the feeding roller 2 is absorbed into the upper packaging film 16. The heat-sealing roller 15 continues to rotate to the position of the tangent point with the heating roller 12, the heating roller 12 is driven by the power equipment to compound the lower packaging film 11 with the upper packaging film 16 of the heat-sealing roller 15, and the packaging of the metal powder material is completed through the hot pressing of the heat-sealing roller 15 and the heating roller 12.
The invention can pack metal powder material circularly and continuously, to solve the problem of low qualification rate, improve the packing speed, reduce the cost and improve the working efficiency. In addition, the feeding roller 2 and the heat sealing roller 15 do not need to process the magnet 4 into a cylindrical or semi-cylindrical shape, so that the production difficulty of the roller is greatly reduced, and the cost of packaging production is further reduced.

When the metal powder material in the storage box 1 falls into the metering die 3 on the feeding roller 2, the metering die 3 is matched with the scraping plate 17, so that the material quantity falling into the metering die 3 can be limited, and the consistency of the packaged metal powder material quantity is effectively ensured. Wherein, the metering mold 3 and the heat sealing mold 14 are made of high-temperature resistant insulating materials so as to prevent the adhesion of metal powder materials and the mold. The scraping plate 17 can be made of any material capable of scraping materials, and the cleaning brush 7 can be made of other fixed soft brushes or other devices capable of cleaning the metering die 3.
Example 3:
preferably, to better realize the present invention, further optimization is performed on the basis of the above embodiment, and the following arrangement is adopted in particular:
