Description

Technical Field

[0001] This invention relates to the field of metal fiber felt production equipment, and in particular to a flipping device for metal fiber felt. Background Technology

[0002] Metal fiber felt is made by laying down metal fibers with a diameter of micrometers and then sintering them at high temperature to obtain the finished product. Metal fiber felt has a three-dimensional network structure, a porous structure, high porosity, large surface area, and uniform pore size distribution, exhibiting excellent structural properties. It is widely used in medical filtration, purification, noise reduction, and hydrogen production industries.

[0003] The most critical step in felt preparation is laying the felt into a mesh. The semi-finished felt formed by this step consists of multiple layers of randomly overlapping fibers forming a uniform porous structure. This structure ensures the stability of important parameters such as porosity and pore size in the finished felt. The semi-finished felt has a certain thickness (usually greater than 2 cm) and lacks an independent support structure, making it highly susceptible to stretching and deformation. Therefore, during transfer between processes, external forces often cause the evenly distributed fibers to be stretched or piled up, resulting in uneven pore size distribution and quality defects in the sintered and shaped fiber felt. Furthermore, in production practice, a soft padding layer, such as kraft paper, is laid underneath the fiber felt after cutting in the previous process. This soft padding layer is difficult to transfer. Therefore, how to transfer the fiber felt to the next sintering process and remove the kraft paper while avoiding deformation is a major challenge in fiber felt production. Moreover, existing transfer or handling devices for metal fiber felt can only transfer or handle metal fiber felt of uniform thickness, making them unsuitable for transporting metal fiber felt of different thicknesses, resulting in poor applicability. Summary of the Invention

[0052] The following is combined with Figures 1-4 This invention describes a flipping device for metal fiber felt. The flipping device for metal fiber felt includes: a workbench 11, a flipping frame 1, a first clamp 2, and a second clamp 3.

[0053] The tilting frame 1 is a frame structure and is rotatably mounted on the worktable 11, specifically, as follows: Figure 1As shown, the workbench 11 includes a slot for accommodating the flipping frame. The flipping frame 1 has a rectangular frame structure and is provided with a first shaft 7 and a second shaft 8. The first shaft 7 and the second shaft 8 are respectively connected to the flipping frame 1. The flipping frame 1, the first shaft 7, and the second shaft 8 are coaxial, and the first shaft 7 and the second shaft 8 pass through the inner wall of the slot and are rotatably connected to the workbench 11. Bearings are sleeved at the rotatable connection. For ease of operation, a handle is vertically connected to the end of the first shaft 7 that extends outside the workbench 11. In addition, the flipping frame 1 flips around its central axis. Compared with the flipping of a book, it has a small flipping radius, making flipping less strenuous and more efficient. The first clamp 2 and the second clamp 3 can be respectively attached to the first shaft 7 so that the first clamp 2, the second clamp 3, and the flipping frame 1 rotate synchronously.

[0054] The first clamp 2 detachably holds the first partition, and the second clamp 3 detachably holds the second partition. The first clamp 2 and the second clamp 3 are respectively sleeved inside the flipping frame 1 and are both hinged to the inner wall of the flipping frame 1 at their first ends. The second ends of the first clamp 2 and the second clamp 3 can be connected to the flipping frame 1 or the worktable 11 to position the first clamp 2 and the second clamp 3. When the first clamp 2 and the second clamp 3 rotate around their first ends and close at their second ends, the first partition and the second partition can be respectively disposed on both sides of the metal fiber felt and clamp the metal fiber felt. The distance between the first ends of the first clamp and the first ends of the second clamp in the height direction is adjustable.

[0055] This invention features a rational structure, including a flipping frame with two hinged clamps, each with a partition. After the soft padding layer and the semi-finished metal fiber felt are moved horizontally into the clamps, the soft padding layer can be easily removed by rotating the flipping frame. Simultaneously, the semi-finished fiber felt is placed on the partitions. The partitions are relatively flat and made of high-temperature resistant material, allowing for direct use in subsequent sintering processes. This not only facilitates transport but also ensures that the semi-finished fiber felt does not deform during transport, thus improving the quality of the sintered product. Furthermore, this flipping device is suitable even for large-format semi-finished fiber felt, offering excellent flexibility.

[0056] Furthermore, the first and second clamps of the present invention are adjustable in height, which not only enables the clamping of metal fiber felt, but also allows for adjustment of the height interval between the first connecting plate 121 and the second connecting plate 122 to accommodate metal fiber felt of different thicknesses; in some cases, the metal fiber felt can also be compressed.

[0057] In this embodiment, the first clamp 2 and the second clamp 3 have the same structure, both including a rectangular frame, such as... Figure 3As shown, the cross-section of the rectangular frame is approximately L-shaped, including a vertical plate and a horizontal plate. It may also include a first pressure plate 4, one end of which is hinged to the vertical plate of the first plate clamp 2 via a torsion spring, so that the other end of the first pressure plate 4 can press the first partition plate firmly onto the horizontal plate of the first plate clamp 2. It may also include a second pressure plate 5, one end of which is hinged to the vertical plate of the second plate clamp 3 via a torsion spring, and the other end of the second pressure plate 5 can press the second partition plate firmly onto the horizontal plate of the second plate clamp 3.

[0058] In other embodiments of the present invention, the first partition can be inserted into the first clamp 2, and the second partition and the second clamp 3 can be inserted into each other. To facilitate flipping the first clamp 2 and the second clamp 3, the first clamp 2 and the second clamp 3 are respectively provided with a first handle and a second handle near the first shaft 7.

[0059] In other embodiments of the present invention, the device further includes: a first driving unit, a first transmission unit, a second driving unit, and a second transmission unit. The first driving unit is connected to the tilting frame 1; one end of the first transmission unit is connected to the first driving unit, and the other end is connected to the second end of the first clamp 2, to drive the first clamp 2 to rotate around its first end; the second driving unit is connected to the tilting frame 1; one end of the second transmission unit is connected to the second driving unit, and the other end is connected to the second end of the second clamp 3, to drive the second clamp 3 to rotate around its first end.

[0060] Specifically, the first drive unit is hinged to the tilting frame 1, and the first transmission unit can be a first piston rod, the end of which is hinged to the second end of the first plate clamp 2 to drive the first plate clamp 2 to rotate around its first end; the second drive unit is hinged to the tilting frame 1, and the second transmission unit can be a second piston rod, the end of which is hinged to the second end of the second plate clamp 3 to drive the second plate clamp 3 to rotate around its first end. It has a high degree of automation and is convenient for automated control.

[0061] Furthermore, to facilitate the positioning of the flipping frame 1 and ensure it remains horizontal without external force, thus facilitating the transfer of the soft padding layer and its semi-finished fiber felt into the flipping frame 1, as follows: Figure 2 As shown, at least one pair of first magnetic strips 6 are provided on the outer side of the flipping frame 1, and the axis of the first magnetic strips 6 is parallel to the axis of the flipping frame 1. Two second magnetic strips with opposite magnetism to the first magnetic strips 6 are provided at the corresponding positions on the inner wall of the slot. In this way, the flipping frame 1 can automatically maintain the horizontal turntable under the action of magnetic force to avoid tipping over. The present invention uses magnetic force to position the flipping frame 1. Compared with mechanical positioning, it is not only simple in structure, low in cost, and easy to maintain, but also occupies less space.

[0062] The first plate clamp 2 detachably holds the first partition, and the second plate clamp 3 detachably holds the second partition. In this invention, the spacing between the first partition and the second partition is adapted to the thickness of the semi-finished metal fiber felt. In other embodiments of this invention, the spacing between the first partition and the second partition can also be set to be adjustable to accommodate semi-finished metal fiber felt of different thicknesses.

[0063] The first and second partitions are made of high-temperature resistant metals, high-temperature resistant alloys, or high-temperature resistant ceramic materials to facilitate subsequent sintering processes. Materials such as stainless steel, nickel alloys, chromium alloys, copper alloys, titanium alloys, manganese alloys, molybdenum alloys, and tungsten alloys can be selected by those skilled in the art according to their needs.

[0064] like Figure 2 As shown, the first clamp 2 and the second clamp 3 are sleeved inside the tilting frame 1 and are both hinged to the inner wall of the tilting frame 1 at their first ends. The second ends of the first clamp 2 and the second clamp 3 can be connected to the tilting frame 1 or the worktable 11 to position the first clamp 2 or the second clamp 3. Specifically, the second end of the first clamp 2 is connected to a first connecting component 9, and the second end of the second clamp 3 is connected to a second connecting component 10. The first connecting component 9 and the second connecting component 10 can be respectively attached to the first shaft 7 so that the first clamp 2, the second clamp 3 and the tilting frame 1 rotate synchronously. The first connecting component 9 includes a first U-shaped part 91. The first connecting rod 92 and the first U-shaped member 91 have their openings facing upwards, spanning the side wall of the tilting frame 1 and having a first arc-shaped groove for accommodating the first shaft 7. In addition, the first U-shaped member 91 has a first insertion hole 93 on the cantilever plate away from the tilting frame 1. The first connecting rod 92 is generally arc-shaped, and the two free ends of the first connecting rod 92 have first insertion blocks that can be inserted into the first insertion hole 93. In this way, the first connecting rod 92 can be engaged with the first U-shaped member 91 to jointly form an accommodating cavity for accommodating the first shaft 7, so that the first plate clamp 2 and the tilting frame can rotate synchronously. The first plate clamp 2 and the second plate clamp 3 can be respectively attached to the first U-shaped member 91. The second connecting component 10 includes a second U-shaped member and a second connecting rod. The second U-shaped member has its opening facing downwards and spans the side wall of the flipping frame 1. It is provided with a second arc-shaped groove for accommodating the first shaft 7. In addition, the first U-shaped member has a second insertion hole on the cantilever plate away from the flipping frame 1. The second connecting rod is generally arc-shaped, and the two free ends of the second connecting rod are provided with second insertion blocks that are inserted into the second insertion hole. In this way, the second connecting rod can be engaged with the second U-shaped member to jointly form an accommodating cavity for accommodating the first shaft 7, so that the second plate clamp 3 can also rotate synchronously with the flipping frame. Furthermore, the first connecting rod 92 and the second connecting rod are staggered.

[0065] In this invention, the first connecting component has a simple structure, which can position the first plate clamp and rotate synchronously with the flipping frame. The second connecting component also has a simple structure, which can position the second plate clamp and rotate synchronously with the flipping frame. Furthermore, the first and second U-shaped components have latches and slots on their opposite end faces, making operation convenient. In addition, the outer side of the flipping frame and the corresponding worktable have two magnetic strips of opposite polarity, which can automatically position the flipping frame to a horizontal position, saving time and effort and increasing efficiency. Moreover, the first shaft, the second shaft, and the flipping frame's axis coincide, resulting in a smaller flipping radius compared to a book-flipping mechanism, making flipping less strenuous and more efficient.

[0066] like Figure 3 As shown, when the second ends of the first clamp 2 and the second clamp 3 are closed and engaged with the first shaft 7, the first partition and the second partition can be respectively disposed on the upper and lower sides of the metal fiber felt and clamp the metal fiber felt. Furthermore, the two cantilever plates of the first U-shaped member 91 and the second U-shaped member, away from the flipping frame 1, are respectively provided with a latch and a slot. Specifically, the latch is provided on the first U-shaped member 91; the slot is provided on the second U-shaped member. The latch and the slot can engage with each other to facilitate positioning of the first clamp and the second clamp before assembling the first connecting rod 92 and the second connecting rod.

[0067] The following settings can be used to allow for adjustable spacing between the first clamp 2 and the second clamp 3 in the height direction: (e.g.) Figure 4 As shown, the metal fiber felt flipping device further includes a first connecting plate 121, a second connecting plate 122, a locking member 123, and an elastic member 124. The first connecting plate 121 is fixed to the first end of the first clamp 2 and has a first through hole along its height direction. The second connecting plate 122 is fixed to the first end of the second clamp 3 and has a second through hole along its height direction. The locking member 123 passes through the first and second through holes in sequence. The elastic member 124 is sleeved on the outside of the locking member 123, with one end fixed to the first connecting plate 121 and the other end fixed to the second connecting plate 122. The elastic member 124 provides pre-tightening force, which, through the first connecting plate 121 and the second connecting plate 122, causes the first clamp 2 and the second clamp 3 to press together, thereby compressing the metal fiber felt. In this embodiment, the above-described configuration not only enables the clamping of the metal fiber felt, but also allows for the adjustment of the height interval between the first connecting plate 121 and the second connecting plate 122 via the locking element, making it suitable for clamping metal fiber felts of different thicknesses. In some cases, the compressive force of the elastic element 124 and the locking force of the locking element can also be used to compress the metal fiber felt.

[0068] Optionally, the height spacing between the first plate clamp 2 and the second plate clamp 3 can be adjusted by using bolts, nuts and bearings. The bolt is connected to the first through hole through the bearing, so that the bolt is fixed to the first through hole in the axial direction, but the bolt can rotate in the first through hole through the bearing. The second through hole can be a threaded hole, and the bolt is screwed into the second through hole accordingly. The bolt is tightened by using a nut, thereby adjusting the height spacing between the first connecting plate 121 and the second connecting plate 122.

[0069] Furthermore, the device also includes: a nut; the locking element 123 is a bolt, which is screwed into the first through hole and the second through hole in sequence. One end of the bolt head is engaged with the first through hole, and the nut is sleeved on the other end of the bolt to adjust the distance between the first connecting plate 121 and the second connecting plate 122. Using a bolt allows for convenient adjustment of the distance between the first connecting plate 121 and the second connecting plate 122, thereby adjusting the distance between the first plate clamp 2 and the second plate clamp 3. Specifically, the through hole near the bolt head can be a round hole, and the through hole away from the bolt head can be a threaded hole. The cooperation between the nut and the bolt achieves the limiting of the first connecting plate 121 and the second connecting plate 122.

[0070] like Figure 4 As shown, the spring is at its maximum elastic compression in the initial state, at which point the distance between the two fixed-distance plates is the smallest. When it is necessary to adjust the thickness of the felt to be clamped, the bolt can be rotated counterclockwise (loosening the bolt). At this time, the first connecting plate 121 and the second connecting plate 122 are supported by the spring under the premise that the spring releases its compression, and the distance becomes larger. The increased size can be displayed through the scale 13 parallel to the bolt, thus completing the thickness increase adjustment; conversely, the thinning adjustment can be completed.

[0071] In one embodiment of the present invention, the first connecting plate 121 is provided with a plurality of first through holes; the second connecting plate 122 is provided with a plurality of second through holes; the locking member 123 passes through the corresponding first and second through holes in sequence to adjust the parallelism between the first connecting plate 121 and the second connecting plate 122. In this embodiment, a plurality of bolts, first through holes, and second through holes can be provided. Preferably, bolts are used for limiting at both ends of the first connecting plate 121 and the second connecting plate 122. The parallelism at both ends of the first connecting plate 121 and the second connecting plate 122 can be adjusted by the tightening of the bolts at both ends. It can be seen that the bolts can adjust the parallelism of the first connecting plate 121 and the second connecting plate 122, thereby ensuring that the parallelism of the felt is qualified before and after flipping.

[0072] The above-mentioned complete set of equipment can be used with a transfer vehicle for transportation. For example, a transfer vehicle can be set up around the workbench 11 to respond to the transfer or handling of the metal fiber felt flipping equipment or the metal fiber felt on it. By using it in conjunction with the transfer vehicle, fully automated production can be achieved in a whole production line.

[0073] The working process of the above-mentioned equipment includes:

[0074] First, the first plate clamp 2 is equipped with a first partition plate, and the second plate clamp 3 is equipped with a second partition plate. The second end of the first plate clamp 2 is connected to the first shaft 7 under the action of the first connecting rod 92. Then, the second connecting rod is pulled out, and the second plate clamp 3 is manually flipped upward.

[0075] Then, another operator drags the soft pad and moves the soft pad and the semi-finished fiber felt on it onto the first partition.

[0076] Then, manually flip the second plate clamp 3 downwards, and use the second connecting rod to make the second plate clamp 3 overlap the first shaft 7;

[0077] Afterwards, the operator holds the handle and rotates the tilting frame 180°, then pulls out the first connecting rod 92, manually flips the first plate clamp 2 upwards, and removes the soft padding layer.

[0078] Next, open the second pressure plate 5, take out the second partition and the semi-finished metal fiber felt on it, and transfer both to the sintering process;

[0079] Afterwards, the operator holds the handle and rotates the tilting frame another 180° to move the next soft pad and the semi-finished metal fiber felt on it onto the first partition.

[0080] Afterwards, the operator fixed another second partition plate onto the second plate clamp 3 via the second pressure plate 5.

[0081] This cycle repeats itself.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
