Description

Technical Field

[0001] This invention relates to the field of automatic explosives loading technology, and in particular to a powder material feeding device that can simultaneously and quantitatively load multiple mold cavities into a mold. Background Technology

[0002] When gunpowder is subjected to an appropriate ignition impulse, it can produce a rapid chemical reaction and release sufficient heat and a large amount of gaseous products, thereby creating a certain mechanical destructive effect and a projectile effect.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0036] See Figure 1 , Figure 2 , Figure 3 This invention provides a powdered material feeding device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the device may include:

[0037] A support assembly, the support assembly including a base plate 1, and a guide shaft 2 disposed above the base plate 1;

[0038] The feeding assembly includes a hopper 3 with an open bottom, the hopper 3 being slidably connected to the guide shaft 2 and the bottom of the hopper 3 abutting against the upper surface of the base plate 1;

[0039] The upper mold assembly includes an upper template 4, which is slidably connected to the guide shaft 2 and fixedly connected to the hopper 3 via a connecting plate 5.

[0040] The lower mold assembly includes a lower template 6, which is connected to the bracket and located below the base plate 1;

[0041] A pressing assembly, the pressing assembly including a pressing mold 7, the pressing mold 7 being located below the guide shaft 2;

[0042] The feeding drive assembly 8 is connected to the pressing assembly and the connecting plate 5 respectively. The feeding drive assembly 8 is used to drive the feeding assembly and the upper mold assembly to move synchronously along the axial direction of the guide shaft 2 to switch positions between the first position and the second position.

[0043] The pressing mold 7 includes at least one pressing cavity 71, and the pressing assembly includes at least one pressing cylinder 72 corresponding to the pressing cavity 71. The pressing cylinder 72 is used to provide molding pressure to the material in the pressing cavity 71. The upper mold plate 4 includes at least one upper mold cavity 41, and each upper mold cavity 41 is provided with an upper mold cylinder 42. The lower mold plate 6 includes at least one lower mold cavity 61, and each lower mold cavity 61 is provided with a lower mold cylinder 62. The base plate 1 is provided with at least one through hole opposite to the at least one lower mold cavity 61.

[0044] In the first position, at least one upper mold cavity 41 and at least one lower mold cavity 61 are vertically opposite each other and the hopper 3 is in the feeding position, so that the lower mold cylinder 62 pushes the material in the lower mold cavity 61 into the corresponding upper mold cavity 41;

[0045] In the second position, at least one upper mold cavity 41 and at least one pressing mold cavity 71 are vertically opposite each other, and the hopper 3 and the lower mold plate 6 are vertically opposite each other, so that the upper mold cylinder 42 pushes the material in the upper mold cavity 41 into the corresponding pressing mold cavity 71 and the material in the hopper 3 enters the lower mold cavity 61 through the through hole.

[0046] The powder material feeding device provided in this application embodiment includes a feeding component and an upper mold component connected by a connecting plate 5 to form an integral structure. The feeding drive component 8 can drive the feeding component and the upper mold component to move synchronously along the axial direction of the guide shaft 2.

[0047] When both the feeding component and the upper mold component are in the first position, the hopper 3 can receive materials from the top.

[0048] When both the feeding assembly and the upper mold assembly are in the second position, the hopper 3 is opposite to the lower mold assembly. Since the bottom of the hopper 3 is open, the material in the hopper 3 will enter the lower mold cavity 61 for temporary storage under the combined action of gravity and the downward suction force of the lower mold cylinder 62.

[0049] When both the feeding assembly and the upper mold assembly move to the first position again, the upper mold cavity 41 and the lower mold cavity 61 are vertically aligned, and the lower mold cylinder 62 moves upward to push the material in the lower mold cavity 61 into the upper mold cavity 41 for temporary storage.

[0050] When both the feeding assembly and the upper mold assembly move to the second position again, the upper mold cavity 41 and the pressing mold cavity 71 are vertically aligned, and the upper mold cylinder 42 moves downward to push the material into the pressing mold cavity 71.

[0051] When both the feeding assembly and the upper mold assembly return to the first position, the upper mold plate 4 exits the pressing assembly, driving the pressing cylinder 72 to descend and press the material in the pressing cavity 71 into shape. Simultaneously, the feeding process into the lower mold cavity 61 can also be performed. This process is repeated to achieve continuous pressing and shaping of powdered materials.

[0052] It is understood that, in practical applications, to improve production efficiency, this embodiment may also provide multiple pressing cavities 71, upper cavities 41, and lower cavities 61, each comprising the same number and arranged vertically relative to the other. Each pressing cavity 71 corresponds to a pressing cylinder 72, each upper cavity 41 contains an upper mold cylinder 42, and each lower cavity 61 contains a lower mold cylinder 62. This method enables independent control of individual cavities, allows for simultaneous production of multiple cavities, and allows for controlling different numbers of cavities for production as needed. Furthermore, the number and position of through holes on the base plate 1 can be set to be relatively consistent with the number and position of the lower cavities 61.

[0053] To prevent material leakage in the lower mold cavity 61 during the process of being pushed into the upper mold cavity 41, this embodiment of the application may also provide a sealing assembly. The sealing assembly includes a sealing cylinder 9 and at least one sealing sleeve. The sealing cylinder 9 is connected to the lower mold assembly, and the sealing sleeve is fitted onto the outside of the lower mold cavity 61 and connected to the actuating end of the sealing cylinder 9. In the second position, the sealing cylinder 9 drives the sealing sleeve upward to seal the gap between the opposing upper mold cavity 41 and lower mold cavity 61. Before the lower mold cylinder 62 moves upward, the sealing cylinder 9 can first drive the sealing sleeve to seal the gap between the upper mold cavity 41 and the lower mold cavity 61, ensuring that material will not be exposed through the gap when the lower mold cylinder 62 moves, thus improving production safety.

[0054] Since the upper mold plate 4 needs to be transferred from above the lower mold plate 6 to above the pressing mold 7 after the material enters the upper mold cavity 41, there is a risk that material in the upper mold cavity 41 may fall out during this transfer process because the bottom of the upper mold cavity 41 is open. In order to solve this problem, this application embodiment can provide a material leakage baffle 10 and a baffle driving cylinder. The baffle driving cylinder is used to drive the material leakage baffle 10 to block the upper mold cavity 41 or release the upper mold cavity 41.

[0055] During the process of material being pushed from the lower mold cavity 61 into the upper mold cavity 41, the baffle drive cylinder can pull the funnel baffle to the outside, ensuring that the bottom of the upper mold cavity 41 is open. After the material in the upper mold cavity 41 has been received, during the transfer to the pressing mold 7, the baffle drive cylinder can push the funnel baffle to the bottom of the upper template 4, sealing the upper mold cavity 41 and ensuring that the material will not fall out of the upper mold cavity 41 during the transfer process. The material discharge baffle 10 and the baffle drive cylinder are carried along by the upper template 4. When the upper template 4 is aligned with the pressing mold 7, the baffle drive cylinder can pull the funnel baffle to the outside, making the bottom of the upper mold cavity 41 open again, and the upper mold cylinder 42 can smoothly push the material in the upper mold cavity 41 into the pressing mold cavity 71.

[0056] In order to physically isolate the pressing component from the hopper 3 side when in the first position, this embodiment of the application may also provide a protective door 11 and a protective door drive cylinder 12. The protective door 11 is slidably connected to the side of the pressing component facing the feeding component. The protective door drive cylinder 12 is connected to the pressing component and the protective door 11 respectively. The protective door drive cylinder 12 is used to drive the protective door 11 to move up and down so that the protective door 11 closes or opens the passage of the pressing component.

[0057] Understandably, powdered materials tend to accumulate and become difficult to fall after being stored in the hopper 3. Therefore, this embodiment of the application provides a paddle 13 inside the hopper 3, and a hydraulic motor is provided on the outside of the hopper 3 to drive the paddle 13. After entering the hopper 3, the material can be fluffed up by the stirring action of the paddle 13, making it easier to enter the lower mold cavity 61 under the action of gravity and the suction force of the lower mold cylinder 62.

[0058] To further improve the feeding effect, this application embodiment may also provide a pneumatic vibrator on the hopper 3, which is used to assist in vibration feeding in the second position.

[0059] In order to ensure that the material on the surface of the lower mold cavity 61 can be scraped flat after the material is fed into the lower mold cavity 61, this embodiment of the application may also provide that the hopper 3 is provided with silicone scrapers on both sides along the axial direction of the guide shaft 2, and the lower ends of the silicone scrapers abut against the surface of the base plate 1.

[0060] To seal the lower mold assembly and prevent material leakage, this embodiment of the application may also provide a dust cover 14 connected to the guide shaft 2, which is used to encapsulate the lower mold assembly. Furthermore, the bottom of the dust cover 14 is provided with an exhaust / exhaust channel.

[0061] To ensure that the device can be in a fully sealed state during operation and improve the safety of the device, this application embodiment may also provide a material cover 31 on the top of the hopper 3, and the material cover 31 is connected to an opening and closing drive cylinder.

[0062] The following describes in detail the structure and usage of the powder material feeding device provided in this application embodiment, taking the setting of components such as sealing components, leakage baffle 10, protective door 11 and multiple mold cavities as examples.

[0063] The inner side of the hopper 3 is equipped with blades for stirring. The hopper 3 is sealed by the material cover 31 driven by the cylinder. The hydraulic motor is fixed on the outer side of the hopper 3 and drives the inner blades to stir and feed the material through the shaft. A pneumatic vibrator is installed on the outer wall of the hopper 3 to assist in vibration feeding.

[0064] Upper mold cylinders 42 are installed one-to-one in the upper mold cavity 41 of the upper mold plate 4. The upper mold cylinders 42 can slide within the upper mold cavity 41. The material leakage baffle 10 is fixed below the upper mold plate 4. The hopper 3 is fixed to the upper mold plate 4 through the connecting plate 5. The hopper 3 and the upper mold plate 4 are fixed on the guide shaft 2. The feeding cylinder (feeding drive assembly 8) is fixed on both sides of the pressing assembly. The piston rod of the feeding cylinder (feeding drive assembly 8) is fixed on the connecting plate 5. The hopper 3 and the upper mold plate 4 are driven to move back and forth through the guide shaft 2.

[0065] The guide shaft 2 is fixed above the bracket via a support base. The lower template 6 is fixed on the bracket. The lower mold cylinders 62 are installed one-to-one in the lower mold cavities 61 of the lower template 6. The sealing cylinder 9 is installed on the lower template 6. The protective cover is fixed on the bracket to encapsulate the lower template 6 for dust protection. The bracket and the pressing assembly are fixedly connected. The protective door 11 is installed on the side of the pressing assembly via a linear guide rail. The pressing mold 7 is fixed inside the pressing assembly. The press cylinder is installed above the pressing mold 7 to drive the pressure rod to slide up and down.

[0066] The protective door 11 is installed on the side of the pressing component to physically isolate the feeding of the hopper 3 and the pressing action of the pressing component; the protective cover encloses the lower template 6 as a whole, and the dust cover 14 has a reserved exhaust channel at the bottom; when the hopper 3 moves back and forth, silicone scrapers are installed at the front and back of the hopper 3 to scrape and collect excess powdery materials.

[0067] The hopper 3 and the upper template 4 are connected together. When the feeding drive assembly 8 drives the upper template 4 to feed material, the hopper 3 simultaneously feeds the lower template 6. After the upper template 4 enters the pressing assembly, it stops directly above the pressing mold 7. The upper mold cylinder 42 pushes out to press the material into the hole of the pressing mold 7, completing the feeding action. While the upper mold cylinder 42 is performing the feeding action, the hopper 3 also stops above the lower template 6. The pneumatic vibrator starts, and the paddle blades 13 stir to fill the cavity of the lower template 6 with material. After the upper mold cylinder 42 completes the feeding, it retracts and moves out. The upper mold plate 4 moves directly above the lower mold plate 6. The sealing cylinder 9 of the lower mold plate 6 drives the sealing sleeve to push out to achieve a sealing effect. The lower mold cylinder 62 pushes out, transferring the material from the mold cavity of the lower mold plate 6 to the mold cavity of the upper mold plate 4. At this time, due to the pressure of the lower mold cylinder 62, the material will be compressed to a certain extent. The material is pressed into the upper mold cylinder 42 and will be adsorbed inside the cylinder of the upper mold frame. At the same time, the material leakage baffle 10 extends to block the material until the upper mold cylinder 42 performs the ejection action and the material will fall off.

[0068] The specific working process of the device provided in this application embodiment is described as follows:

[0069] The cylinder drives the material cover 31 to open the hopper 3, and the powdery material is added into the hopper 3. The material cover 31 closes, and at the same time the hydraulic motor drives the blades to stir the material and make it fluffy.

[0070] The equipment begins its working cycle:

[0074] C. The powdery material in hopper 3 is fed out by the agitation of the blades and the vibration of the pneumatic vibrator. At the same time, the lower mold cylinder 62 descends, creating a vacuum, and the powdery material is added into the lower mold cavity 61 through the through hole on the bottom plate 1.

[0075] D. The upper template 4 moves above the pressing mold 7 without any movement because there is no powdery material in the upper mold cavity 41.

[0076] Cycle 2:

[0077] E. The feeding drive assembly 8 drives the hopper 3 and the upper template 4 to move laterally to the first position through the guide shaft 2, moving the hopper 3 to the feeding position. At the same time, the upper template 4 moves above the lower template 6, so that the upper mold cavity 41 and the lower mold cavity 61 are vertically opposite each other.

[0078] F. The protective door 11 descends to isolate the pressing components and the feeding station.

[0079] G. The sealing cylinder 9 rises and drives the sealing sleeve to move upward, so that the lower mold cavity 61 and the upper mold cavity 41 are sealed and connected. Then the lower mold cylinder 62 rises and pushes the powdered material from the lower mold cavity 61 into the upper mold cavity 41. At the same time, the upper mold cylinder 42 rises and pre-presses the powdered material into shape.

[0080] H. The sealing cylinder 9 descends, and at the same time, the lower mold cylinder 62 descends. The material leakage baffle 10 is driven by the cylinder to seal the pre-compressed material in the upper mold cavity 41.

[0081] Cycle 3:

[0082] 1. The protective door 11 rises to ensure that the pressing cylinder 72 is above the pressing assembly;

[0083] J. The feeding drive assembly 8 drives the hopper 3 and the upper template 4 to move laterally to the second position through the guide shaft 2, moving the hopper 3 above the lower template 6, while the upper template 4 moves above the pressing mold 7.

[0084] K. The powdery material in hopper 3 is fed out by the agitation of the blades and the vibration of the pneumatic vibrator. At the same time, the lower mold cylinder 62 descends to create a vacuum, adding the powdery material into the lower mold cavity 61.

[0085] L. When the material leakage baffle 10 is opened, the upper mold cylinder 42 pushes the pre-compressed material in the upper mold cavity 41 into the pressing mold cavity 71 of the pressing mold 7.

[0086] Cycle 4:

[0087] M. The feeding drive assembly 8 drives the hopper 3 and the upper template 4 to move laterally to the first position through the guide shaft 2, moving the hopper 3 to the feeding position, while the upper template 4 moves above the lower template 6.

[0088] N, the protective door 11 descends, isolating the pressing components and the feeding station.

[0089] O. The sealing cylinder 9 rises, driving the lower mold cavity 61 and the upper mold cavity 41 to seal and connect. Then the lower mold cylinder 62 rises, pushing the powdered material from the lower mold cavity 61 into the upper mold cavity 41. At the same time, the upper mold cylinder 42 rises, pre-pressing the powdered material into shape.

[0090] P. The sealing cylinder 9 descends, and at the same time, the lower mold cylinder 62 descends. The material leakage baffle 10 is driven by the cylinder to seal the pre-compressed material in the upper mold cavity 41.

[0091] Q. The pressing cylinder 72 descends, pressing the pre-pressed powdery material in the pressing mold 7 into shape.

[0092] Then, by repeating cycle three and cycle four, the automated production of quantitative feeding of powdered materials in groups and pressing of materials in presses can be completed, realizing automated and unmanned production, and meeting the requirements of efficient and safe production of explosives loading and feeding.

[0093] In summary, the powder material feeding device provided in this application can transfer material from the hopper to the cavity of the pressing mold through the upper and lower mold components.
