Description

Technical Field

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

[0002] Metal powders such as titanium alloys and aluminum alloys are used to produce complex structures such as aerospace components and biomedical implants through additive manufacturing technology, and have characteristics such as light weight and high strength. However, metal powders will contact and oxidize with oxygen in the air. In addition, in a dry environment, metal powders will increase flow friction when contacting air during the filling process, and static sparks are likely to be generated. There are potential safety hazards and it affects subsequent use. Therefore, packaging needs to be carried out in a vacuum environment.

[0003] A patent document with publication number CN118205787A discloses a production device for packaging metal alloy powders, including a filling box. Inside the filling box, there is a packaging can for containing metal alloy powders, and a filling component for conveying metal alloy powders into the packaging can. The filling box is also connected to a gas supply component for conveying a specified gas. Inside the filling box, there is a detection module for detecting the concentration of the specified gas in the filling box. The detection module is electrically connected to a controller. The side wall of the filling box is also connected to an air outlet pipe, and a first valve is arranged on the air outlet pipe. Both the gas supply component and the first valve are controlled by the controller. Based on the detection result of the detection module, the controller controls the opening and closing of the first valve and the gas supply component. During filling, a specified gas is conveyed into the filling box through the gas supply component, and at the same time, gas is discharged through the air outlet pipe. After changing the gas composition in the filling box, the metal powder is filled into the packaging can.

[0004] However, there are still the following problems in this solution. After the packaging can is conveyed into the filling box, new gas is introduced through the gas supply component, and at the same time, the original gas is discharged through the air outlet pipe to adjust the air composition inside the filling box. However, due to the uncontrollability of the gas, it is impossible to ensure that the original gas is completely discharged. In addition, the gas input by the gas supply component will mix with the original gas in the filling box, making it difficult to completely discharge the original gas in the filling box. Only new gas can be continuously introduced to dilute the concentration of the original gas in the filling box. The process is cumbersome and affects the packaging efficiency. Summary of the Invention

[0005] The present invention provides a metal powder packaging device, aiming to solve the problem that the efficiency of adjusting the gas composition in the filling box is low in the related art, resulting in affecting the packaging efficiency.

[0006] The metal powder packaging equipment of the present invention includes a material tank and a filling pipe located at the bottom of the material tank. An installation plate is provided at the bottom of the material tank, and a driving component and an auxiliary frame are provided below the installation plate; a sealing sleeve connecting the two is provided between the auxiliary frame and the filling pipe. The auxiliary frame includes a plurality of auxiliary plates that are rotatably connected to each other. The driving component is connected to the diagonal corners of the auxiliary frame to control the retraction and expansion of the auxiliary frame. The auxiliary plate includes a telescopic part for adjusting its length, and an adjusting component and a ventilation component are provided on the auxiliary plate. The adjusting component is connected to the telescopic part to control the telescoping of the auxiliary plate. The ventilation component includes an air extraction pipe and a ventilation pipe that communicate with the inside of the packaging bag; the packaging bag is sleeved outside the retracted auxiliary frame, the adjusting component controls the auxiliary plate to extend, so that the outside of the auxiliary frame closely adheres to the inside of the packaging bag to fix the packaging bag. After the air extraction pipe extracts the air in the packaging bag, the ventilation pipe injects inert gas into the packaging bag. Subsequently, the driving component controls the auxiliary frame to expand, and finally the filling pipe fills the metal powder.

[0007] The effect is that in the initial state, the auxiliary frame is in a retracted state, and the telescopic part is contracted, and the auxiliary plate is also in a retracted state. Then the packaging bag is sleeved outside the auxiliary frame, and then the adjusting component drives the telescopic part to extend, so that the auxiliary plate extends. As the auxiliary plate extends, the opening of the packaging bag is propped up until the outside of the auxiliary plate abuts against the inner side of the packaging bag. Then the original gas in the packaging bag is extracted through the air extraction pipe, and then inert gas is injected into the packaging bag through the ventilation pipe. Subsequently, the driving component drives the auxiliary frame to open, and then the filling pipe moves down into the packaging bag to fill the metal powder into the packaging bag. During the process of air extraction and ventilation, the auxiliary frame is still in a retracted state to facilitate air extraction and inflation, improving the efficiency of gas replacement in the packaging bag and thus improving the packaging efficiency.

[0008] Preferably, the two diagonal corners of the auxiliary frame are respectively an adjustment position and a sliding position. The driving component includes a driving part and a connecting plate provided at the output end of the driving part. The connecting plate is connected to the adjustment position of the auxiliary frame, and a slider is provided at the sliding position of the auxiliary frame. The slider slides on the installation plate in a direction perpendicular to the filling pipe.

[0009] The effect is that the driving part drives the connecting plate to move, thereby driving the two adjustment positions on the auxiliary frame to move away from each other and expanding the auxiliary frame.

[0010] Preferably, the auxiliary plate includes connecting parts provided at both ends of the telescopic part. The auxiliary plate is rotatably connected to the adjacent auxiliary plate through the connecting parts. The adjusting component includes an adjusting pipe and an elastic part. The elastic part is arranged inside the telescopic part and is connected to the connecting parts at both ends of the telescopic part to drive the telescopic part to retract. The adjusting pipe is arranged on the connecting part. One end of the adjusting pipe is connected to an air pump, and the other end passes through the connecting part and communicates with the inside of the telescopic part. When the adjusting pipe is inflated, the telescopic part expands under the action of positive pressure.

[0011] The effect is that the elastic member drives the two connecting parts closer, so that the auxiliary plate is in a retracted state. Air is introduced into the telescopic part through the air pipe, and the telescopic part extends under positive pressure, thereby driving the auxiliary plate to open.

[0012] Preferably, rubber layers are provided on both the inner and outer sides of the auxiliary plate. When the auxiliary frame is in a retracted state, the rubber layers on the inner side of the auxiliary plate abut against each other to close the inside of the auxiliary frame. When the auxiliary plate extends, it abuts against the inner side of the packaging bag through the rubber layer on its outer side.

[0013] The effect is that when the auxiliary frame is retracted, the rubber layers on the inner side of the auxiliary plate abut against each other to improve the sealing performance when the auxiliary frame is retracted. At the same time, when the auxiliary frame is unfolded, the rubber layer on the outer side of the auxiliary plate abuts against the inner side of the packaging bag to improve the sealing performance when the auxiliary frame cooperates with the packaging bag.

[0014] Preferably, a connecting ring is slidably assembled up and down on the outside of the filling pipe, and the sealing sleeve is connected to the connecting ring.

[0015] The effect is that the filling pipe can move up and down in the connecting ring, reducing the phenomenon that the sealing sleeve interferes with the movement of the filling pipe.

[0016] Preferably, a heat-sealing component is provided on the mounting plate. There are two groups of heat-sealing components arranged around the filling pipe. The heat-sealing component includes a first pusher and a heat-sealing plate. The heat-sealing plate is arranged at the output end of the first pusher. The two heat-sealing plates are arranged in parallel at intervals. The heat-sealing plate is arranged below the auxiliary frame for heat-sealing the packaging bag.

[0017] The effect is that after filling is completed, the first pusher drives the heat-sealing plate to move, and the packaging bag is clamped by the two heat-sealing plates to seal the packaging bag.

[0018] Preferably, a bag feeding component is provided below the auxiliary frame. There are two groups of bag feeding components. The bag feeding component includes a second pusher, a connecting plate, and a suction nozzle. The output end of the second pusher is connected to the connecting plate. The connecting plates in the two groups of bag feeding components are arranged parallel to each other. The suction nozzle is arranged on the connecting plate and is located between the two connecting plates.

[0019] The effect is that after the suction nozzles adsorb on both sides of the packaging bag, the second pusher drives the two connecting plates to move away from each other, opening the opening of the packaging bag so as to sleeved the packaging bag outside the auxiliary frame.

[0020] Preferably, a plurality of suction nozzles are arranged at intervals along the length direction of the connecting plate.

[0021] The effect is to improve the stability of the opened packaging bag.

[0022] Preferably, a third pusher is provided below the second pusher. The output end of the third pusher is connected to the second pusher to drive the second pusher to move up and down. When the second pusher moves up, the suction nozzles drive the opening of the packaging bag to be sleeved outside the auxiliary frame.

[0023] The effect is that after the packaging bag is opened, the third pusher drives the second pusher to move upward, and the opening of the packaging bag is sleeved outside the auxiliary frame.

[0024] Preferably, a slide plate is arranged below the third pusher, and the slide plate is slidably assembled left and right below the auxiliary frame to convey the packaging bag to the auxiliary frame.

[0025] The effect is that after the packaging bag is placed at the suction nozzle, the slide plate is moved to the auxiliary frame for subsequent operations.

[0026] Beneficial effects: By setting the auxiliary frame in the present invention, the auxiliary frame can be extended to support the packaging bag in the retracted state, then the gas in the packaging bag is pumped out, and then inert gas is introduced into the packaging bag through the ventilation pipe. Finally, the auxiliary frame is unfolded, and the filling pipe extends into the packaging bag for filling, so that the gas in the packaging bag can be quickly replaced, improving the packaging efficiency.

DETAILED DESCRIPTION

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figures 1 to 7 As shown, the metal powder packaging equipment of the present invention includes a frame 1, a filling component, an auxiliary component, a driving component 5, an adjusting component 8, a ventilation component 9, and a bag delivery component 11. The filling component is arranged on the frame 1, the driving component 5 and the adjusting component 8 are both connected to the auxiliary component, the ventilation component 9 is arranged on the auxiliary component, and the bag delivery component 11 is used to transfer the packaging bag to the auxiliary component. Under the action of the driving component 5 and the adjusting component 8, the auxiliary component props up the opening of the packaging bag, and then ventilates through the ventilation component 9 to replace the air components in the packaging bag, and finally fills the metal powder into the packaging bag through the filling component.

[0037] Reference Figure 1 The filling assembly includes: a material tank 2 and a filling tube 3. The material tank 2 is arranged on the frame 1. The filling tube 3 is arranged at the bottom of the material tank 2, and the filling tube 3 is slidably assembled on the material tank 2. The auxiliary assembly is arranged near the lower end of the filling tube 3. The metal powder raw material is placed in the material tank 2. During filling, the filling tube 3 moves downward so that its lower end extends into the packaging bag to fill the metal powder.

[0038] Reference Figure 2 , Figure 3 , Figure 4 The auxiliary components include: a mounting plate 4, an auxiliary frame 6, and a sealing sleeve 7. The mounting plate 4 is arranged on the frame 1, and the mounting plate 4 is assembled at the bottom of the material tank 2. The filling tube 3 penetrates the mounting plate 4 downward and extends to the bottom of the mounting plate 4. The auxiliary frame 6 is arranged below the mounting plate 4. The auxiliary frame 6 is sleeved on the outside of the filling tube 3. The sealing sleeve 7 is arranged between the filling tube 3 and the auxiliary frame 6, and is respectively connected to the two. The sealing sleeve 7 is made of elastic rubber and is used to seal the gap between the auxiliary frame 6 and the filling tube 3.

[0039] Reference Figure 2 , Figure 4 A connecting ring 31 is slidably mounted on the outside of the filling tube 3, and the sealing sleeve 7 is connected to the connecting ring 31, so that the filling tube 3 can move up and down in the connecting ring 31, reducing the phenomenon that the sealing sleeve 7 interferes with the movement of the filling tube 3.

[0040] Reference Figure 3 , Figure 4 , Figure 5, the auxiliary frame 6 includes a plurality of auxiliary plates 61 that are rotatably connected to each other. In this embodiment, there are four of them. The plurality of auxiliary plates 61 are arranged on the same horizontal plane, and when the auxiliary frame 6 is unfolded, the plurality of auxiliary plates 61 enclose a parallelogram structure. The driving assembly 5 is connected to one of the diagonals of the auxiliary frame 6 to adjust the distance between the diagonals of the auxiliary frame 6, so as to drive the auxiliary frame 6 to unfold or retract. The ventilation assembly 9 is arranged on the auxiliary plate 61.

[0041] Refer to Figure 3 , Figure 4 , Figure 5 , the auxiliary plate 61 includes a telescopic part 611 and a connecting part 612. There are two connecting parts 612, and the two connecting parts 612 are respectively arranged at both ends of the telescopic part 611. The telescopic part 611 is arranged as a square corrugated plate, that is, the telescopic part 611 can be telescoped to adjust the distance between the two connecting parts 612. The connecting part 612 is rotationally matched with the connecting part 612 on the adjacent auxiliary plate 61. The adjusting assembly 8 is connected to the telescopic part 611.

[0042] In the initial state, the diagonal of the auxiliary frame 6 corresponding to the driving assembly 5 abuts, and the auxiliary frame 6 is in the retracted state. At this time, the inside of the auxiliary frame 6 is in the closed state to evacuate the packaging bag. At this time, the auxiliary frame 6 is in a long strip shape. At the same time, the adjusting assembly 8 drives the telescopic part 611 to contract, and the auxiliary plate 61 shortens.

[0043] The auxiliary frame 6 has two states: retracted and unfolded. When the auxiliary frame 6 is in the retracted state, one of the diagonals approaches and abuts each other, and the auxiliary frame 6 is in a long strip shape. When the auxiliary frame 6 is in the unfolded state, the two diagonals of the auxiliary frame 6 are both far away from each other until the angle between every two adjacent auxiliary plates 61 is the same. At this time, the lower end of the filling pipe 3 can pass through the auxiliary frame 6 and move into the packaging bag.

[0044] When the auxiliary frame 6 is in the retracted state, the auxiliary plate 61 also has two states. One is that when the telescopic part 611 contracts, the auxiliary plate 61 is in the contracted state, and at this time the length of the auxiliary plate 61 is shortened to the shortest. The other is that when the telescopic part 611 elongates, the auxiliary plate 61 is in the elongated state, and at this time the length of the auxiliary plate 61 gradually extends to the longest. Therefore, in these two states of the auxiliary plate 61, although the retracted auxiliary frame 6 is in a long strip shape, the lengths are different. When the auxiliary plate 61 is retracted, it is convenient to put the packaging bag on the outside of the auxiliary frame 6, and when the auxiliary plate 61 is elongated, it is closely attached to the inside of the packaging bag.

[0045] Place the packaging bag outside the auxiliary frame 6 through the bag feeding assembly 11, and then the adjusting assembly 8 drives the telescopic part 611 to extend, that is, drives the auxiliary plate 61 to extend until the outer side of the auxiliary plate 61 abuts against the inner side of the packaging bag. Subsequently, the ventilation assembly 9 performs a ventilation operation on the packaging bag. After the ventilation is completed, the driving assembly 5 drives the distance between the diagonals of the auxiliary frame 6 to increase, expands the auxiliary frame 6, and the filling pipe 3 moves downward and extends into the packaging bag through the auxiliary frame 6 for filling.

[0046] Rubber layers are provided on both the inner and outer sides of the auxiliary plate 61. When the auxiliary frame 6 is in the retracted state, the rubber layers on the inner side of the auxiliary plate 61 abut against each other, so that when the auxiliary frame 6 is retracted, the sealing performance when the inside of the auxiliary frame 6 is closed is improved through the rubber layer, facilitating the subsequent ventilation operation. When the auxiliary plate 61 extends, the auxiliary plate 61 abuts against the inner side of the packaging bag through the rubber layer on the outer side, thereby improving the sealing performance of the cooperation between the auxiliary plate 61 and the packaging bag, and also facilitating the subsequent ventilation operation.

[0047] Refer to Figure 4 、 Figure 5 、 Figure 6 As shown in

[0048] The ventilation assembly 9 includes: an air extraction pipe 91 and a ventilation pipe 92. The air extraction pipe 91 and the ventilation pipe 92 are respectively connected to an air pump. The air extraction pipe 91 and the ventilation pipe 92 are both arranged on the auxiliary plate 61, and the air extraction pipe 91 and the ventilation pipe 92 pass through the auxiliary plate 61 and extend to the lower side of the auxiliary plate 61. After the auxiliary plate 61 extends to fix the packaging bag, both the air extraction pipe 91 and the ventilation pipe 92 are communicated with the inside of the packaging bag.

[0049] Refer to Figure 5 As shown in

[0050] Refer to Figure 3 、 Figure 4, there are two sets of driving components 5, and the two sets of driving components 5 respectively correspond to the two adjustment positions 613 of the auxiliary frame 6. The driving component 5 includes: a driving member 51 and a connecting plate 52. The driving member 51 is arranged on the mounting plate 4, the driving member 51 is set as a cylinder, the connecting plate 52 is arranged at the output end of the driving member 51, and the connecting plate 52 is connected to the adjustment position 613 of the auxiliary frame 6. The driving member 51 drives the connecting plate 52 to move, and drives the auxiliary frame 6 to unfold or fold up through the connecting plate 52.

[0051] Refer to Figure 6 , the adjusting component 8 includes: an adjusting pipe 81 and an elastic member 82. The elastic member 82 is arranged in the telescopic part 611, and the elastic member 82 is respectively connected to the connecting parts 612 at both ends of the telescopic part 611. The elastic member 82 is set as an elastic telescopic rod, and the elastic member 82 is used to drive the two connecting parts 612 to move towards each other. The adjusting pipe 81 is arranged on the connecting part 612, one end of the adjusting pipe 81 is connected to the air pump, and the other end extends into the telescopic part 611.

[0052] In the initial state, the elastic member 82 drives the telescopic part 611 to contract. When it is necessary to fix the packaging bag, the telescopic part 611 is inflated through the adjusting pipe 81. Under the action of positive pressure, the telescopic part 611 drives the two connecting parts 612 to move and move away from each other, so that the auxiliary plate 61 grows.

[0053] Refer to Figure 2 、 Figure 4 , a heat-sealing component 41 is arranged on the mounting plate 4, and there are two sets of heat-sealing components 41 arranged around the filling pipe 3. The heat-sealing component 41 includes: a first pushing member 411 and a heat-sealing plate 412. The first pushing member 411 is set as a cylinder, the heat-sealing plate 412 is arranged at the output end of the first pushing member 411, and the heat-sealing plates 412 in the two sets of heat-sealing components 41 are arranged parallel to each other. The heat-sealing plate 412 is arranged below the auxiliary frame 6.

[0054] After filling is completed, the driving member 51 drives the auxiliary frame 6 to fold up through the connecting plate 52, and then the first pushing member 411 drives the heat-sealing plate 412 to approach the packaging bag, so that the heat-sealing plate 412 clamps the packaging bag for heat-sealing packaging.

[0055] Refer to Figure 2 、 Figure 7 , the bag feeding component 11 is arranged below the auxiliary frame 6, there are two sets of bag feeding components 11, the bag feeding component 11 includes: a second pushing member 111, a connecting plate 112 and a suction nozzle 113. The second pushing member 111 is set as a cylinder, the output end of the second pushing member 111 is connected to the connecting plate 112, the connecting plates 112 on the two sets of bag feeding components 11 are arranged parallel and spaced apart, the suction nozzle 113 is arranged on the connecting plate 112, and the suction nozzle 113 is located between the two connecting plates 112.

[0056] Place the upper end of the packaging bag between the two connecting plates 112, then the suction nozzle 113 adsorbs the side of the packaging bag, and the second pusher 111 drives the two connecting plates 112 away from each other to open the opening of the packaging bag.

[0057] A plurality of suction nozzles 113 are arranged along the length direction of the connecting plate 112 to improve the stability when the packaging bag is opened.

[0058] Refer to Figure 2 、 Figure 7 As shown in, a third pusher 12 is arranged below the second pusher 111. The third pusher 12 is set as a cylinder, and the output end of the third pusher 12 is connected to the second pusher 111. The third pusher 12 is used to drive the second pusher 111 to move up and down. After the packaging bag is opened, the third pusher 12 drives the packaging bag to move upward to sleeved the outside of the auxiliary frame 6.

[0059] Refer to Figure 2 、 Figure 7 As shown in, a slide plate 13 is arranged below the third pusher 12. The slide plate 13 is slidably assembled on the frame 1, and the slide plate 13 slides left and right on the frame 1. After the packaging bag is placed between the connecting plates 112, the slide plate 13 slides to the lower part of the auxiliary frame 6 for subsequent operations.

[0060] The implementation principle of the present invention is as follows: in the initial state, the auxiliary plate 61 is retracted into a long strip shape, and the telescopic part 611 is in a contracted state; the suction nozzle 113 adsorbs the packaging bag, and at the same time, the second pusher 111 opens the opening of the packaging bag through the connecting plate 112. After the slide plate 13 moves to the lower part of the auxiliary frame 6, the third pusher 12 drives the packaging bag to move upward and sleeved the outside of the auxiliary frame 6.

[0061] Air is introduced into the telescopic part 611 through the regulating pipe 81. Under the action of positive pressure, the telescopic part 611 extends, and at the same time drives the auxiliary plate 61 to extend. The auxiliary plate 61 extends to abut against the inner side of the packaging bag until the rubber layer on the outer side of the auxiliary plate 61 abuts against the inner side of the packaging bag. Then the air in the original packaging bag is pumped out by the air extraction pipe 91, and then inert gas is introduced into the packaging bag through the air supply pipe 92.

[0062] Then the driving member 51 drives the connecting plate 52 to move. After driving the auxiliary frame 6 to unfold, the filling pipe 3 moves downward into the packaging bag to fill the metal powder. After the filling is completed, the driving member 51 drives the auxiliary frame 6 to retract, and then the packaging bag is heat-sealed by the heat-sealing plate 412.

[0063] By setting the auxiliary frame 6, when the auxiliary frame 6 is retracted, the packaging bag is propped up by adjusting the length of the auxiliary plate 61. At the same time, when the auxiliary frame 6 is in the retracted state, the space inside the packaging bag is isolated from the outside world. Then, ventilation is carried out through the air extraction pipe 91 and the ventilation pipe 92. After the gas inside the packaging bag is pumped out, an inert gas is introduced to improve the efficiency of replacing the gas inside the packaging bag, reduce the oxidation and other phenomena of the metal powder during packaging due to contact with the outside air, and improve the packaging efficiency.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
