Description

Technical Field

[0001] The invention belongs to the technical field of 3D printing, and in particular is a 3D printing metal powder packaging machine. Background Art

[0002] 3D printing metal powder is usually packaged in plastic bags. When the powder is bagged, the plastic bag needs to be opened at the powder discharge port, the opening of which needs to be aligned with the discharge port and the bag needs to be kept stable. When the bag is opened manually, it is easy to cause the bag to shake and spill during the loading process. In addition, during the loading process, the scattered powder will float in the air, causing the operator to inhale a large amount of powder, which can cause certain harm to the human body.

[0003] In the prior art, during the bagging process of 3D printing metal powder, there is often a certain distance between the bagging port and the feeding port, which will cause the 3D metal powder to scatter to a certain extent, resulting in a waste of resources.

[0004] After searching, it is found that a clamp for powder bagging is disclosed in a Chinese patent document (publication number: CN214875952U). The present invention relates to the technical field of powder packaging equipment and discloses a clamp for powder bagging, wherein the clamp is arranged on the side wall of a rectangular tubular discharge port, and the clamp comprises at least one group of clamping mechanisms, each group of clamping mechanisms comprises a pair of clamping assemblies respectively arranged on two opposite side walls of the rectangular tubular discharge port, and the clamping assembly comprises a fixed clamping block, a movable clamping block and a swinging assembly, wherein the fixed clamping block is fixedly arranged on the side wall of the discharge port, and the swinging assembly can drive the movable clamping block to be close to or away from the fixed clamping block, and an anti-slip protrusion is provided on the side of the fixed clamping block facing the movable clamping block, and an anti-slip groove matching the anti-slip protrusion is provided on the side of the movable clamping block facing the fixed clamping block. This clamp effectively improves the clamping effect of the clamp by arranging matching anti-skid protrusions and anti-skid grooves on the moving and fixed clamping blocks, reduces the leakage of powder during packaging, and thus reduces product waste. However, there are still the following defects:

[0005] Although the above-mentioned clamp for powder bagging has achieved effective improvement of the clamping effect of the clamp by arranging matching anti-skid protrusions and anti-skid grooves on the dynamic and fixed clamping blocks, and reduced leakage during powder packaging, thereby reducing product waste, there is still a problem that although the scattering of 3D powder can be reduced by the clamp, since this type of operation is often an assembly line operation, this method is difficult to meet the needs of assembly line operations and requires manual assistance for the operation, resulting in poor work efficiency.

[0031] By setting up the buffer component, when the storage bag for 3D metal powder storage is placed on the device during use, the buffer component will be in the initial state, so that the storage bag for 3D metal powder storage is accurately aligned with the 3D metal powder discharge port, and as the 3D metal powder discharge port discharges the 3D metal powder to the storage bag for 3D metal powder storage, the weight of the storage bag for 3D metal powder storage increases, and then the support arm 10 is compressed, thereby compressing the return spring 13. Under this condition, the storage bag for 3D metal powder storage steadily descends and is always aligned with the 3D metal powder discharge port, which can reduce the falling of 3D metal powder, and during use, the weight parameter threshold of the storage bag for 3D metal powder storage is acquired in real time through the weight sensor 3, and the acquired weight parameter threshold is transmitted to the bagging processing system 2 for intelligent management.

[0032] Specifically, the top end of the connecting block 7 is fixedly connected to the bottom end of the top plate 14 of the "U"-shaped structure, and the interior of the top plate 14 is penetrated and fixedly connected with a placement cavity 15 of the hollow structure, the four inner walls of the placement cavity 15 are penetrated and fixedly connected with a mounting shell 16, and one end of the mounting shell 16 inside the placement cavity 15 is fixedly connected with a high-density metal mesh plate 17, the end of the mounting shell 16 away from the high-density metal mesh plate 17 is fixedly connected with a dustproof air intake net, and a plurality of centrifugal fans 18 are fixedly connected at equal intervals inside the mounting shell 16.

[0033] By setting up the centrifugal fan 18, after the storage bag that needs to store 3D metal powder is placed inside the placement chamber 15, the centrifugal fan 18 is started to generate centrifugal force, so that the four sides of the storage bag can be centrifugally adsorbed, so that the outer surfaces are respectively in contact with the corresponding outer surfaces of the high-density metal mesh plate 17, thereby completing the expansion operation of the storage bag.

[0034] Furthermore, a heat sealing device body 20 and a heat insulation plate 25 are respectively arranged at the top of the top plate 14 and the center point of the placement cavity 15, and the heat sealing device body 20 and the heat insulation plate 25 are arranged in a horizontal corresponding structure, one end of the heat sealing device body 20 is fixedly connected to the output end of the cylinder 19, one end of the heat insulation plate 25 is fixedly connected to one end of the connecting block 24, and the end of the connecting block 24 away from the heat insulation plate 25 is symmetrically fixedly connected with a connecting spring 23, the connecting spring 23 is symmetrically fixedly connected to one end inside the connecting shell 22, and the inner end of the connecting shell 22 is fixedly connected to a pressure sensor 26 located between the two connecting springs 23, the pressure sensor 26 is electrically connected to the bagging processing system 2, and the connecting shell 22 is fixedly connected to the top of the top plate 14 through the mounting frame 21.

When the insulation board 25 collides with the heat sealing device body 20, the connecting spring 23 will be compressed, so that the monitoring end of the pressure sensor 26 collides with the connecting block 24 to generate a pressure parameter threshold, and the pressure parameter threshold is transmitted to the bagging processing system 2 for processing.

[0036] Furthermore, the outer walls on both sides of the connecting seat 4 are fixedly connected to the connecting arms 27 of the "L"-shaped structure, and one end of the connecting arm 27 is connected to the outer wall of the transmission screw sleeve 28, the transmission screw sleeve 28 is meshed and connected to the outer wall of the connecting screw 29, and the bottom end of the connecting screw 29 is fixedly connected to the top of the rotating block movably connected inside the rotating cavity, the bottom end of the rotating block is fixedly connected to the top of the control knob 31, the rotating cavity is opened inside the connecting seat 30, and one end of the connecting seat 30 is fixedly connected to the front end of the base 1.

[0037] By setting the control knob 31, during use, according to the required bag size, the control knob 31 can be used to rotate forward or reverse, thereby linking the connecting screw 29 to rotate forward or reverse, and then through the screw transmission structure composed of the connecting screw 29 and the transmission screw sleeve 28, the connecting seat 4 and the components above the connecting seat 4 are driven to adjust the height, thereby adjusting the distance between the top of the placement cavity 15 and the base 1.

This can save the power consumption of the heat sealing device body 20, and at the same time, the quantity parameter data of the storage bag completed packaging can be obtained.

[0039] Principle and process of the present invention:

[0040] First, such a 3D printing metal powder packaging machine is used. First, the storage bag for storing 3D metal powder is positioned. Specifically, after the storage bag for storing 3D metal powder is placed inside the placement chamber 15, the centrifugal fan 18 is started to generate centrifugal force, so that the four sides of the storage bag can be centrifugally adsorbed, so that the outer surfaces are respectively in contact with the corresponding outer surfaces of the high-density metal mesh plate 17, so that the storage bag is opened;

[0041] Secondly, the buffer assembly is provided to accurately align the storage bag for 3D metal powder storage with the 3D metal powder discharge port, and as the 3D metal powder discharge port discharges the 3D metal powder storage bag, the weight of the storage bag for 3D metal powder storage increases, thereby compressing the support arm 10, thereby compressing the return spring 13, and in this case, the storage bag for 3D metal powder storage steadily descends and is always aligned with the 3D metal powder discharge port;

[0042] Afterwards, the weight parameter threshold of the storage bag storing the 3D metal powder is obtained in real time through the weight sensor 3. When the weight parameter threshold of the storage bag reaches the specified weight parameter data, the first control module is used to control the 3D metal powder discharge port in an early warning manner;

[0043] Then, when the storage bag is finished packing the 3D metal powder, the cylinder 19 outputs work to drive the heat sealing device body 20 to move toward the heat insulation board 25, and after the heat insulation board 25 contacts the heat sealing device body 20, the packaging operation of the storage bag is completed. When the heat insulation board 25 contacts the heat sealing device body 20, the connecting spring 23 will be compressed, so that the monitoring end of the pressure sensor 26 contacts the connecting block 24 to generate a pressure parameter threshold, and the pressure parameter threshold obtained by the pressure sensor 26 controls the heat sealing device body 20 to stop the heating operation, so that the power consumption of the heat sealing device body 20 can be saved, and the quantity parameter data of the storage bag completed packaging can be obtained at the same time;

[0044] Finally, when it is necessary to install storage bags of different sizes, according to the required bag size, the knob 31 can be manipulated to rotate forward or reverse, thereby linking the connecting screw 29 to rotate forward or reverse, and then the connecting screw 29 and the transmission screw sleeve 28 constitute the screw transmission structure, thereby driving the connecting seat 4 and the parts above the connecting seat 4 to adjust the height, thereby adjusting the distance between the top of the placement cavity 15 and the base 1, and thus a 3D printing metal powder packaging machine is completed;
