[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Reference below Figure 1-Figure 12 A bagged powder forming system 100 according to an embodiment of the present invention is described.

[0039] like Figure 1 , Figure 2 and Figure 7 As shown, a bagged powder molding system 100 according to an embodiment of the present invention is used for bagged powder molding. The bagged powder includes a bag body and powder loaded in the bag body. For example, the powder can be silicon powder, metal powder or plastic powder. The bagged powder molding system 100 includes: a conveying device 10, a piercing device 20, a secondary packaging device 30 and a molding device 40.

[0040] Specifically, the conveying device 10 includes a first conveying section 11 and a second conveying section 12. The second conveying section 12 is located at the first conveying section 11 in the conveying direction (for example, Figure 1 That is, the bagged powder first passes through the first conveying section 11 and then moves to the second conveying section 12 during the conveying process (the subsequent descriptions about the upstream and downstream are similar to this), and the conveying device 10 can be a belt conveyor, a mesh belt conveyor or a chain conveyor, etc.

[0041] The piercing device 20 is arranged at the first conveying section 11, and the piercing device 20 includes a piercing needle 222 for piercing the bag body. The secondary packaging device 30 is arranged at the first conveying section 11 and is located downstream of the piercing device 20 in the conveying direction. The secondary packaging device 30 is used to wrap a sleeve film on the surface of the bag body. The forming device 40 is arranged between the first conveying section 11 and the second conveying section 12. The forming device 40 has a mold cavity 42. The forming device 40 includes a pressing mold 41, and the pressing mold 41 is used to extrude the bagged powder located in the mold cavity 42.

[0042] During the operation of the bagged powder forming system 100, the conveying device 10 can automatically convey the bagged powder between processes, avoiding manual handling of the bagged powder between processes, reducing the frequency of workers' contact with the bagged powder, thereby reducing labor intensity and the impact on workers' health and improving production efficiency.

[0043] After the piercing device 20 pierces the bag body, a vent hole is formed on the bag body. The secondary packaging device 30 wraps a film on the surface of the bag body to block the vent hole. It should be noted that when the secondary packaging device 30 wraps the film on the surface of the bag body, the film does not completely seal the bag body. In this way, when the molding device 40 presses the bagged powder of the secondary packaging into shape, the air in the bag body can be squeezed out from the gap between the bag body and the film under the pressure of the pressing mold 41 and the mold cavity 42, thereby reducing the probability of the bag body exploding during the press molding. At the same time, when the bag body is squeezed and exploded, the film can block the splashed powder, reduce the degree of powder splashing from the mold cavity 42, improve the environment of the work site, and thus reduce the impact of the work site environment on the health of workers. In addition, the film can reduce the probability of the powder splashed from the bag body exploding and contacting the mold cavity 42, thereby reducing the probability of the powder contacting the mold cavity 42 and introducing impurities into the mold cavity 42 to reduce the purity of the powder.

[0044] When the bagged powder forming system 100 is working, first, the first conveying section 11 conveys the bagged powder to the puncturing device 20, and the puncture needle 222 punctures the bag body to form a vent hole, then the first conveying section 11 conveys the bagged powder to the secondary packaging device 30, and the secondary packaging device 30 wraps a film on the surface of the bag body, then the first conveying section 11 conveys the bagged powder to the mold cavity 42 of the forming device 40, and the pressing mold 41 squeezes the bagged powder in the mold cavity 42 to form the bagged powder, and then the formed bagged powder is conveyed to the subsequent process through the second conveying section 12. Thus, the automated operation process of bagged powder forming is completed.

[0045] According to the bagged powder molding system 100 of the embodiment of the present invention, on the one hand, the automated operation of bagged powder molding can be realized, thereby reducing the labor intensity of workers and the impact on workers' health, and improving production efficiency. On the other hand, the probability of bag explosion during powder molding can be reduced, and the degree of powder splashing when the bag explosion occurs can be reduced, thereby improving the environment of the work site and further reducing the impact on workers' health. In addition, the probability of powder contacting the mold cavity 42 can also be reduced, thereby reducing the probability of introducing impurities into the powder to reduce the purity of the powder.

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the bagged powder forming system 100 further includes: a thrust device 50, which is disposed in the second conveying section 12 and is located upstream of the forming device 40 in the conveying direction (for example Figure 2 The thrust device 50 is used to push the bagged powder on the first conveying section 11 to the forming device 40 and / or push the bagged powder on the forming device 40 to the second conveying section 12. That is, the thrust device 50 can push the bagged powder on the first conveying section 11 to the forming device 40, or push the bagged powder on the forming device 40 to the second conveying section 12, or push the bagged powder on the first conveying section 11 to the forming device 40 and push the bagged powder on the forming device 40 to the second conveying section 12.

[0047] In this embodiment, preferably, the thrust device 50 pushes the bagged powder on the first conveying section 11 to the forming device 40, and pushes the bagged powder on the forming device 40 to the second conveying section 12. In this way, automatic loading and unloading of the forming device 40 can be achieved during the working process, thereby realizing the automated operation of bagged powder forming.

[0048] In some embodiments of the present invention, Figure 3 , Figure 5 and Figure 6As shown, the thrust device 50 includes: a thrust piece 51, which is mounted above the conveying device 10 and is movable along the conveying direction to push the bagged powder. In this way, during the operation of the bagged powder forming system 100, when the bagged powder moves to the junction of the first conveying section 11 and the forming device 40, the thrust piece 51 moves toward the forming device 40 on the side of the bagged powder away from the forming device 40, thereby pushing the bagged powder to move into the mold cavity 42. When the bagged powder is completed in the forming device 40 by press-fitting, the thrust piece 51 moves toward the second conveying section 12 on the side of the bagged powder away from the second conveying section 12, thereby pushing the bagged powder from the mold cavity 42 to the second conveying section 12.

[0049] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 6 As shown, the thrust device 50 includes: a lifting mechanism 52, which is connected to the thrust member 51 and is used to drive the thrust member 51 to move in the up and down direction. After the thrust device 50 pushes the bagged powder on the first conveying section 11 to the forming device 40 and / or pushes the bagged powder on the forming device 40 to the second conveying section 12, the thrust device 50 will return to the position before pushing, so as to carry out the next operation process.

[0050] In the process of the thrust device 50 returning to the position before pushing, the lifting mechanism 52 can lift the thrust piece 51 upward so that there is enough avoidance space between the thrust piece 51 and the first conveying section 11, so that the first conveying section 11 can convey the bagged powder to between the thrust piece 51 and the forming device 40. When the first conveying section 11 conveys the bagged powder to the position and the thrust piece 51 returns to the position, the lifting mechanism 52 drops the thrust piece 51 to carry out the next operation process.

[0051] In some embodiments of the present invention, the thrust members 51 include two thrust members 51, which are arranged at intervals along the conveying direction, and each thrust member 51 is connected to at least one lifting mechanism 52. For example, each thrust member 51 can be connected to one, two or three lifting mechanisms 52, so that each lifting mechanism 52 can apply a force to the thrust member 51 to lift the thrust member 51, thereby improving the speed and reliability of the thrust member 51 during the lifting process. The two thrust members 51 are respectively a first thrust member 51a and a second thrust member 51b, and the first thrust member 51a is located downstream of the second thrust member 51b in the conveying direction.

[0052] In the thrust device 50 , automatic loading and unloading in the molding device 40 can be achieved through one of the first thrust member 51 a and the second thrust member 51 b . For example, the first thrust member 51a may be used to realize automatic loading and unloading in the forming device 40. When the thrust member 50 is working, the second thrust member 51b is in a continuously raised state, and the first thrust member 51a is located between the bagged powder to be loaded and the forming device 40. The first thrust member 51a first pushes the bagged powder on the forming device 40 to the second conveying section 12. Then, the first thrust member 51a is raised and moves away from the second conveying section 12 to the upstream of the bagged powder to be loaded and falls. Then, the first thrust member 51a pushes the bagged powder on the first conveying section 11 to the forming device 40. Subsequently, the first conveying section 11 conveys the subsequent bagged powder into place. The first thrust member 51a is raised and returns to between the bagged powder and the forming device 40 and falls. Thus, the process of automatic loading and unloading of the first thrust member 51a in the forming device 40 is completed.

[0053] When it is necessary to realize automatic loading and unloading in the forming device 40 through the second thrust member 51b, it is only necessary to keep the first thrust member 51a in a continuously raised state and then repeat the above process. In this way, when the lifting mechanism 52 connected to one of the thrust members 51 is damaged, automatic loading and unloading operations can still be performed in the forming device 40, thereby improving the reliability of the bagged powder forming system 100.

[0054] In the thrust device 50, the first thrust member 51a and the second thrust member 51b can also be used to realize automatic loading and unloading in the molding device 40. When the thrust device 50 is working, bagged powder is placed on the first conveying section 11 between the first thrust member 51a and the second thrust member 51b. In this way, when the thrust device 50 moves toward the second conveying section 12, the first thrust member 51a can push the bagged powder in the mold cavity 42 to the second conveying section 12, and at the same time, the second thrust member 51b can push the two thrust members 51a and 51b together. The bagged powder between the push pieces 51 is pushed from the first conveying section 11 into the mold cavity 42, and then the lifting mechanism 52 lifts the first thrust piece 51a and the second thrust piece 51b, and the thrust device 50 returns to the position before the push, and the first conveying section 11 conveys the next bagged powder to be processed to between the first thrust piece 51a and the second thrust piece 51b, and then the lifting mechanism 52 drops the first thrust piece 51a and the second thrust piece 51b, and the thrust device 50 performs the next working process according to the production cycle. As a result, the thrust device 50 can load and unload materials in the molding device 40 in a single movement toward the molding device 40, and the moving distance is short, thereby improving production efficiency.

[0055] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 6As shown, the thrust device 50 further includes: a connecting rod 53, the connecting rod 53 extends along the conveying direction, and the thrust piece 51 is arranged on the connecting rod 53 through the lifting mechanism 52. By providing the connecting rod 53, the connecting rod 53 can provide support for the lifting mechanism 52, so as to realize the arrangement of the thrust device 50 on the bagged powder forming system 100, and at the same time, the connecting rod 53 can provide a fulcrum for the lifting mechanism 52, so that the lifting mechanism 52 can lift the thrust piece 51.

[0056] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the bagged powder forming system 100 drives the thrust device 50 through the first driving cylinder 56, and the first driving cylinder 56 is connected to the connecting rod 53 to drive the connecting rod 53 to move along the conveying direction, so as to realize the reciprocating movement of the thrust member 51 along the conveying direction and the lifting and lowering of the lifting mechanism 52. The cylinder moves quickly and has high reliability during the working process. Driving the thrust device 50 through the first driving cylinder 56 can improve the working efficiency and reliability of the bagged powder forming system 100 during the working process.

[0057] In some embodiments of the present invention, Figure 3-Figure 6 As shown, the thrust device 50 further includes a positioning mechanism 54, which is disposed on the connecting rod 53. The positioning mechanism 54 includes a position sensor 541, which is used to detect the position of the thrust member 51 in the up-down direction. During the lifting and lowering process of the thrust member 51, when the position sensor 541 detects that the thrust member 51 reaches the set position in the up-down direction, the lifting mechanism 52 stops lifting and lowering, thereby realizing the automatic control of the lifting mechanism 52, and further realizing the automatic operation process of the bagged powder forming system 100.

[0058] In some embodiments of the present invention, each thrust member 51 corresponds to two position sensors 541, and the position sensors 541 respectively detect the position of the corresponding thrust member 51 in the up and down directions. In this way, the detection accuracy of the position sensor 541 can be improved and the detection efficiency can be improved.

[0059] In some embodiments of the present invention, the position sensor 541 is a photoelectric sensor, and the position sensor 541 is arranged relative to the thrust member 51 to be detected. The photoelectric sensor has a fast response speed and the light is visible. By setting the position sensor 541 as a photoelectric sensor, the detection accuracy of the position sensor 541 can be guaranteed. At the same time, when the position sensor 541 is arranged, the position where the light is irradiated can be observed, which is convenient for adjusting the position of the position sensor 541 when the position sensor 541 is installed. During operation, when the thrust member 51 blocks the light of the photoelectric sensor during the process of lifting and lowering in the up and down directions, the photoelectric sensor detects that the thrust member 51 has reached the specified position, and the lifting mechanism 52 stops the up and down movement of the thrust member 51, thereby realizing the automatic control of the lifting mechanism 52.

[0060] In some embodiments of the present invention, Figure 3-Figure 6 As shown, the thrust member 51 also includes: a thrust frame 55, on which a slide rail 551 extending along the conveying direction is provided, and the connecting rod 53 is slidably provided on the slide rail 551, thereby realizing the arrangement of the thrust device 50 and the movement of the thrust device 50 along the conveying direction, wherein the thrust frame 55 can provide support for the thrust device 50, and the slide rail 551 can provide guidance for the movement of the thrust device 50 and limit the moving path of the thrust device 50.

[0061] In some embodiments of the present invention, the molding device 40 also includes: a lifting mechanism (not shown in the figure), which is arranged at the bottom of the mold cavity 42. In the initial state, the upper surface of the lifting mechanism is in contact with the peripheral wall of the mold cavity 42, and the pressing mold 41 can cooperate with the mold cavity 42 to press-form the bagged powder. In the lifting state, the lifting mechanism lifts the formed bagged powder from the mold cavity 42, so that the thrust member 51 can push the bagged powder from the mold cavity 42 to the second conveying section 12, thereby realizing the automated operation process of unloading the molding device 40.

[0062] In some embodiments of the present invention, Figure 7As shown, the piercing device 20 includes: a piercing frame 21, a needle 222 assembly and a needle 222 driving member. Specifically, the needle 222 assembly is movably arranged on the piercing frame 21. The needle 222 assembly includes a fixed seat 221 and a plurality of needles 222 arranged on the fixed seat 221. The needle 222 driving member is arranged on the piercing frame 21 and connected to the fixed seat 221 for driving the fixed seat 221 to move. When the bagged powder on the first conveying section 11 reaches the process of the piercing device 20, the needle 222 driving member drives the fixed seat 221 to move toward the bagged powder, so that the needle 222 on the fixed seat 221 can pierce the bag body, and then the needle 222 driving member drives the fixed seat 221 to return to the initial position, and the first conveying section 11 conveys the bagged powder to the next process, thereby completing the operation process of the piercing device 20 on the bagged powder. The piercing frame 21 provides support for the piercing device 20, the piercing needle 222 assembly can pierce the bag body, and the piercing needle 222 driving member provides driving force for the working process of the piercing needle 222 assembly.

[0063] In some embodiments of the present invention, the needle 222 driving member is a second driving cylinder, the cylinder moves quickly and has high reliability during operation. By setting the needle 222 driving member as a second driving cylinder, the working efficiency and reliability of the bagged powder forming system 100 during operation can be improved.

[0064] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 8 As shown, the bagged powder forming system 100 also includes: a stacking device 60, which is arranged at one end of the second conveying section 12 away from the first conveying section 11 and is located downstream of the forming device 40, and the stacking device 60 includes a mechanical arm 61 and a clamp 62, and the clamp 62 is arranged at one end of the mechanical arm 61. The stacking device 60 grabs the bagged powder on the second conveying section 12 through the mechanical arm 61 and the clamp 62, and stacks the bagged powder to a preset area. In this way, the bagged powder after being pressed and formed by the forming device 40 can be automatically stacked, further improving the automation degree of the bagged powder forming system 100, improving production efficiency, and avoiding manual stacking by workers, reducing labor intensity and the impact of contact with powder on health.

[0065] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the palletizing device 60 further includes: a safety grating 63 and a material discharging basket 64, wherein the safety grating 63 is arranged around the mechanical arm 61, and the distance between the safety grating 63 and the rotation center of the mechanical arm 61 is greater than the operating radius of the mechanical arm 61, and the material discharging basket 64 is used to stack the bagged powders grabbed by the palletizing device 60. By setting the safety grating 63, it is possible to prevent people from entering the operating radius of the mechanical arm 61. At the same time, when a person enters the interior of the safety grating 63, the palletizing device 60 will stop working, thereby reducing the probability of safety accidents. By setting the material discharging basket, the formed bagged powders can be stored, thereby facilitating the transportation of the formed bagged powders.

[0066] In some embodiments of the present invention, Figure 9-12 As shown, the secondary packaging device 30 includes: a packaging frame 31, a film rolling mechanism 32, a forming mechanism 33, a tensioning mechanism 34 and a cutting and sealing mechanism 35. Specifically, the film rolling mechanism 32 includes a sleeve film rolled up on a rotating shaft, the forming mechanism 33 is arranged on the packaging frame 31, the tensioning mechanism 34 is arranged on the packaging frame 31, the free end of the sleeve film passes through the forming mechanism 33 and is fixed to the tensioning mechanism 34, the cutting and sealing mechanism 35 is arranged downstream of the forming mechanism 33 along the conveying direction, and the cutting and sealing mechanism 35 is used to cut the sleeve film and seal the sleeve film wrapped on the bagged powder.

[0067] When the first conveying section 11 conveys the bagged powder to the secondary packaging device 30 process, the bagged powder first passes under the forming mechanism 33, and the bagged powder contacts the sleeve connected to the forming mechanism 33. Under the push of the bagged powder, the sleeve is pulled out from the rotating shaft of the film rolling mechanism 32 and wraps the bagged powder. Under the conveyance of the first conveying section 11, the bagged powder wrapped with the sleeve arrives at the location of the cutting and sealing mechanism 35, and the cutting and sealing mechanism 35 cuts and seals the sleeve wrapped with the bagged powder, thereby completing the process of the secondary packaging device 30 covering and sealing the punctured bagged powder. It should be noted that the cutting and sealing mechanism 35 does not completely seal the sleeve of the bagged powder, so that the air in the bag can be squeezed out from the gap between the sleeve and the bag, reducing the probability of the bag exploding during the bag pressing and forming process.

[0068] In some embodiments of the present invention, the bagged powder forming system 100 includes a plurality of conveying devices 10, for example, the conveying devices 10 may be two, three or four, and the plurality of conveying devices 10 are arranged at intervals, and the piercing device 20, the secondary packaging device 30, the thrust device 50, and the forming device 40 correspond one-to-one to the conveying device 10. There is at least one stacking device 60, for example, the stacking device 60 may be one, two or three, and the rotation range of the mechanical arm 61 of the stacking device 60 covers the second conveying section 12 of the plurality of conveying devices 10 away from the end of the first conveying section 11, thereby ensuring that the stacking device 60 can grab and stack the bagged powder on each second conveying section 12, thereby improving production efficiency and meeting production needs.
