[0001] This utility model relates to the field of composite material technology, specifically to a single-layer particle filling machine. Background Technology
[0002] Metal matrix composites (MMCs) have established themselves as a new material and technology due to their lightweight structure and excellent physical properties. As MMCs gradually penetrate from military and defense applications to civilian sectors, they have now achieved commercial applications in numerous fields, including land transportation, thermal management, civil aviation, industry, and sports and leisure. While MMCs currently exhibit excellent performance, better cost-effectiveness and processability are prerequisites for commercialization. Currently, existing filling machines cannot produce single-layer particle preforms, thus failing to meet the demands for even superior performance in MMCs. Utility Model Content
[0003] The purpose of this invention is to provide a single-layer particle filling machine to solve the problem that existing filling machines cannot produce single-layer particle preforms.
[0004] To solve the above problems, this utility model proposes a single-layer particle filling machine, and the technical solution adopted is as follows:
[0005] A single-layer particle filling machine includes: a feeding device, the feeding device including a material screen disposed below it, a detachable single-layer particle filling screen disposed below the material screen, particles in the feeding device falling into the holes of the single-layer particle filling screen through the material screen, a particle removal mechanism disposed between the material screen and the single-layer particle filling screen, the particle removal mechanism including a first guide rail and a valve disposed at one end thereto, the first guide rail being arranged parallel to the plane of the single-layer particle filling screen, the valve moving along the first guide rail, and gas being introduced into the valve to remove particles from the single-layer particle filling screen that have not fallen into the holes of the single-layer particle filling screen during the movement, so as to obtain a single-layer particle preform.
[0006] Furthermore, the feeding device also includes multiple material gates, which are arranged above the material mesh to allow the particles in the feeding device to simultaneously and evenly pass through the material mesh and fall into the holes of the single-layer particle filling mesh.
[0007] Furthermore, the feeding device also includes an electronic control switch, which is used to control the simultaneous opening and closing of multiple material gates.
[0008] Furthermore, the particle removal mechanism includes a first guide rail and a valve disposed at one end thereto. The first guide rail is arranged parallel to the plane of the single-layer particle filling mesh. The valve moves along the first guide rail, and gas is introduced into the valve to remove particles that have not fallen into the holes of the single-layer particle filling mesh during the movement.
[0009] Furthermore, the valve is a porous valve, and the porous valve is arranged along a direction perpendicular to the first guide rail.
[0010] Furthermore, the porous valve is connected to a flow control element, which adjusts the airflow according to different particle sizes.
[0011] Furthermore, the feed screen is detachable and its aperture is adjustable according to the particle size.
[0012] Furthermore, the pore size of the single-layer particle-filled mesh is smaller than that of the material mesh.
[0013] Furthermore, a second guide rail is provided below the single-layer particle filling mesh, and the single-layer particle filling mesh slides along the second guide rail to realize the disassembly and replacement of the single-layer particle filling mesh.

[0015] Furthermore, the feeding device includes a hopper, which is positioned above the feed mesh.
[0016] Beneficial Effects: This utility model is an improved utility model. The single-layer particle filling machine of this utility model uses a feed mesh to drop particles from the feeding device into the holes of the single-layer particle filling mesh. Under the blowing action of the air valve, multiple layers of particles on the surface of the single-layer particle filling mesh are removed, realizing the rapid and automated preparation of single-layer particle preforms. This reduces the workload of subsequent workers in patching the particle preforms, effectively improving the preparation of preforms and achieving continuous operation of uniform single-layer particle filling distribution. In other words, it realizes the preparation and continuous production of single-layer particle-reinforced metal matrix composite precursors, thereby achieving automated operation. The single-layer particle preforms obtained by this single-layer particle filling machine can be used to prepare particle-reinforced metal matrix composite precursors of different shapes according to the mesh shape of different particle filling meshes, effectively improving the processability of composite materials. This single-layer particle filling machine is of great significance for the preparation of particle-reinforced metal matrix composites. With increasingly higher requirements for composite materials and increasingly complex composite material structures, the preparation of single-layer particle-reinforced metal matrix composites can effectively reduce the current problem of high processing difficulty in composite materials, and has a certain guiding role in the production and processing of complex composite materials.
[0017] The feeding device also includes multiple material gates, which are located above the material mesh.

[0019] The valve is a porous valve, and the porous valve is arranged in a direction perpendicular to the first guide rail, which facilitates more effective and faster removal of particles that have not fallen into the holes of the single-layer particle filling mesh.

[0025] As cited in the background art, existing filling machines cannot produce single-layer granule preforms. Therefore, this utility model provides a single-layer granule filling machine, including a feeding device for inputting granules; the feeding device includes a feed screen disposed below it for preliminary sieving of the granules; a detachable single-layer granule filling screen is disposed below the feed screen for receiving the pre-screened granules, so that the granules in the feeding device fall into the holes of the single-layer granule filling screen through the feed screen; a granule removal mechanism is disposed between the feed screen and the single-layer granule filling screen, the granule removal mechanism including a first guide rail and a valve disposed at one end thereto, the first guide rail being arranged parallel to the plane of the single-layer granule filling screen, the valve moving along the first guide rail, and gas being introduced into the valve to remove granules on the single-layer granule filling screen that have not fallen into the holes of the single-layer granule filling screen during the movement, so as to obtain a single-layer granule preform. This invention relates to a single-layer particle filling machine. Particles from a feeding device are fed into the pores of a single-layer particle filling mesh via a feed screen. Multiple layers of particles on the surface of the mesh are removed by air blowing through a valve. This enables rapid and automated preparation of single-layer particle preforms, reducing the workload of subsequent preform patching operations and effectively improving preform preparation quality. The single-layer particle preforms obtained by this machine can be used to prepare particle-reinforced metal matrix composite precursors of different shapes, depending on the mesh shape of the particle filling mesh, effectively improving the processability of the composite material.

[0027] Specific embodiment 1 of the single-layer particle filling machine of this utility model:
[0028] In this embodiment, as Figure 1 and Figure 2As shown, a single-layer particle filling machine includes a worktable 2, supported by worktable legs 1. The single-layer particle filling machine is mounted on the worktable 2 and supported by four columns 3. The single-layer particle filling machine also includes a feeding device, which includes a feed screen 4 positioned below it and a hopper 11 positioned above the feed screen 4. A detachable single-layer particle filling screen 5 is positioned below the feed screen 4. Particles from the feeding device fall through the feed screen 4 into the holes of the single-layer particle filling screen 5. A particle removal mechanism is provided between the feed screen 4 and the single-layer particle filling screen 5. The particle removal mechanism includes a first guide rail 6 and a valve at one end. The first guide rail 6 is parallel to the plane of the single-layer particle filling screen 5. The valve moves along the first guide rail 6, and gas is introduced into the valve to remove particles from the single-layer particle filling screen 5 that have not fallen into the holes during the movement, thus obtaining a single-layer particle preform. Specifically, a recovery port is provided at the end of the single-layer particle filling mesh 5 away from the valve. The recovery port is connected to the recovery chamber 10. Gas is introduced into the valve so that, during its movement, the particles on the single-layer particle filling mesh 5 that have not fallen into the holes of the single-layer particle filling mesh 5 are blown to the recovery port and fall into the recovery chamber 10 for recovery.
[0029] In this embodiment, the feeding device also includes multiple material gates positioned above the material mesh 4. These gates allow particles to simultaneously and evenly pass through the material mesh 4 and fall into the holes of the single-layer particle filling mesh 5. The feeding device also includes an electronic control switch, which controls the simultaneous opening and closing of the multiple material gates for easy feeding and receiving. During operation, the electronic control switch is turned on, and the multiple material gates open simultaneously, allowing particles to pass through the material mesh 4 and fall evenly onto the single-layer particle filling mesh 5 and into its holes. After completion, the electronic control switch is turned off, and the multiple material gates close simultaneously, preventing particles from falling.
[0030] Specific embodiment 2 of the single-layer particle filling machine of this utility model:
[0031] Based on the above-described technical concept of this utility model, or based on the specific embodiments of this utility model described above, another embodiment is provided below.
[0032] In this embodiment, the valve is a porous valve 7, specifically a porous cylindrical valve, and the porous valve 7 is arranged along a direction perpendicular to the first guide rail 6. This allows the porous valve 7 to span the single-layer particle packing mesh 5 perpendicular to the first guide rail 6, facilitating more efficient and rapid removal of particles from the single-layer particle packing mesh 5 that have not fallen into its holes. The valve is connected to an air pump via an air passage, and the air pump's opening and closing are controlled by an air valve. Simultaneously, the porous valve 7 is connected to a flow control element 8, which adjusts the airflow according to different particle sizes, facilitating precise control over the removal of particles from the single-layer particle packing mesh 5 that have not fallen into its holes.
[0033] The feed screen 4 can be fixedly installed, and its aperture can be non-adjustable based on the particle size. In this case, only a single-layer particle preform of one particle size can be prepared, which is not convenient for preparing single-layer particle preforms of different particle sizes. Therefore, in this embodiment, preferably, the feed screen 4 is detachable and its aperture is adjustable based on the particle size, which can be used for the initial screening of particles of different sizes to suit different working scenarios. The feed screen 4 can be detached and installed via the first guide rail 6. At the same time, the aperture size of the single-layer particle filling mesh 5 is smaller than that of the feed screen 4, ensuring that particles falling from the feed screen 4 can fill the apertures of the single-layer particle filling mesh 5, thereby allowing the remaining particles not stuck in the apertures of the single-layer particle filling mesh 5 to be blown away by the airflow.
[0034] In other embodiments, the valve may be a single-hole valve, with the single hole on the valve being opened along a direction perpendicular to the first guide rail 6.
[0035] Specific embodiment 3 of the single-layer particle filling machine of this utility model:
[0036] Based on the above-described technical concept of this utility model, or based on the specific embodiments of this utility model described above, another embodiment is provided below.
[0037] In this embodiment, a second guide rail 9 is provided below the single-layer particle filling mesh 5, and the single-layer particle filling mesh 5 slides along the second guide rail 9 to realize the disassembly and replacement of the single-layer particle filling mesh 5.
[0038] In other embodiments, the single-layer particle filling mesh 5 is provided with a buckle. When in use, the buckle is locked to fix the single-layer particle filling mesh 5 on the single-layer particle filling machine. When it is necessary to disassemble and replace, the buckle is opened to facilitate the disassembly and replacement of the single-layer particle filling mesh 5.
[0039] The working principle of this single-layer particle filling machine is as follows:
[0040] First, ceramic particles of a specific size range are placed in the hopper 11 and evenly spread. Then, the electric control switch is turned on, controlling the multiple material gates to open simultaneously. The ceramic particles fall through the material mesh 4, allowing them to be evenly spread in the single-layer particle filling mesh 5. Next, the electric control switch is turned off, controlling the multiple material gates to close. Then, the air valve is opened, and the flow control element 8 is adjusted according to the size of the ceramic particles. After the air is evenly released, the first guide rail 6 is activated, causing the multi-hole air valve 7 to advance at a certain speed, blowing away the excess ceramic particles on the single-layer particle filling mesh 5. Finally, only one layer of particles remains evenly spread in the holes of the single-layer particle filling mesh 1, while the remaining particles enter the recycling bin 10. Then, the single-layer particle filling mesh 5 with ceramic particles is removed through the second guide rail 9, and a new single-layer particle filling mesh 5 is placed in through the second guide rail 9. The electric control switch and the multiple material gates are then turned on again, and the operation is repeated to achieve continuous production.
[0041] From the above description of specific embodiments of the single-layer particle filling machine of this utility model, it can be seen that the single-layer particle filling machine of this utility model includes a feeding device for inputting particles; the feeding device includes a material screen disposed below it for preliminary screening of particles; a detachable single-layer particle filling screen is disposed below the material screen for receiving the preliminary screened particles, so that the particles in the feeding device fall into the holes of the single-layer particle filling screen through the material screen; a particle removal mechanism is disposed between the material screen and the single-layer particle filling screen, the particle removal mechanism includes a first guide rail and a valve disposed at one end thereto, the first guide rail is disposed parallel to the plane of the single-layer particle filling screen, the valve moves along the first guide rail, and gas is introduced into the valve so that it removes particles on the single-layer particle filling screen that have not fallen into the holes of the single-layer particle filling screen during the movement, so as to obtain a single-layer particle preform. This invention relates to a single-layer particle filling machine. Particles from a feeding device are fed into the pores of a single-layer particle filling mesh via a feed screen. Multiple layers of particles on the surface of the mesh are removed by air blowing through a valve. This enables rapid and automated preparation of single-layer particle preforms, reducing the workload of subsequent preform patching operations and effectively improving preform preparation quality. The single-layer particle preforms obtained by this machine can be used to prepare particle-reinforced metal matrix composite precursors of different shapes, depending on the mesh shape of the particle filling mesh, effectively improving the processability of the composite material.
