Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal fiber felt production equipment, specifically a novel metal fiber felt stacking device. Background Art
[0002] Metal fiber felt is a porous material made of fine interwoven metal fibers. It has unique physical and chemical properties, such as high porosity, high temperature resistance, and corrosion resistance, and is suitable for a variety of industrial applications, such as filter media, catalyst carriers, heat exchangers, and electromagnetic shielding.
[0003] There are two forms of metal fiber felt production: one is that the fiber filaments are suspended in a liquid environment and then naturally settle, and the other is that the fiber filaments float in an atmospheric environment and then settle, forming a felt-like structure. The single-layer metal fiber felt strip needs to be cut into sheets first, then layered and laid, and then sintered to form a semi-finished product. As is well known, before sintering, the single-layer metal fiber felt is soft and has no self-support. If it is subjected to external force during transportation or laying, it is very easy for the evenly distributed fiber filaments to be stretched or piled up, resulting in uneven pore size distribution and inconsistent quality in the final product.
[0004] In current production practices, single-layer metal fiber felt is often laid manually. During the transportation and laying process, the fiber felt is subjected to external forces, which can cause the fiber filaments to be stretched or stacked, which is not conducive to improving the quality of the finished product.
[0005] In existing technologies, mechanical stacking methods are also used, such as... Figure 1 As shown, to adapt to the existing fiber felt production line, the cutting blade cuts the strip fiber felt output from the production line. The cut fiber felt is then fed into the receiving platform by the feeding unit. The receiving platform moves left and right to complete the stacking of fiber felt. When an odd number of fiber felt layers need to be stacked, the receiving platform moves to the right to complete the stacking. When an even number of fiber felt layers need to be stacked, the receiving platform moves to the left to complete the stacking. This method is suitable for continuous production but is not conducive to improving production efficiency.
[0006] In addition, if Figure 1 As shown, an arc-shaped connection area is formed between adjacent layers of fiber felt. This arc-shaped connection area needs to be cut off before entering the next process, or after a subsequent process. This not only wastes fiber felt, but also, when stacked, the arc-shaped connection area is prone to squeezing adjacent fiber felt, which is not conducive to improving the uniformity of fiber felt pore size distribution and thus not conducive to improving the quality of the finished product. Utility Model Content
[0007] This utility model discloses a novel metal fiber felt stacking device, which solves the technical problems of existing fiber felt stacking methods being unable to adapt to continuous production and hindering the improvement of the uniformity of pore size distribution in the finished product. It features a reasonable structure, adaptability to continuous production, and the ability to improve the uniformity of pore size distribution in the finished product after stacking. The technical solution adopted is as follows:
[0008] A novel metal fiber felt stacking device includes a feeding unit, a pallet, a circulation unit, and a controller. The feeding unit includes a first conveyor belt that conveys the cut sheet-like fiber felt forward. Multiple pallets are provided to receive and transport the fiber felt fed from the feeding unit. The circulation unit includes a track assembly and a drive unit. The track assembly supports the pallets upwards. The drive unit is electrically connected to the controller and can drive the pallets to move along the loop of the track assembly, allowing the pallets to repeatedly receive fiber felt from the feeding unit to complete the fiber felt stacking. Alternatively, the drive unit can drive the pallets out of the track assembly to transfer them to the next workstation.
[0009] Based on the above technical solution, the track assembly includes a bracket and a plurality of drive rollers disposed on the bracket, the drive rollers supporting the tray upward and driving the tray to move.
[0010] Based on the above technical solution, the plurality of transmission rollers include multiple independent transmission roller groups, and the driving unit includes sub-driving components that are arranged one-to-one with the multiple transmission roller groups. The sub-driving components can drive the transmission roller groups at corresponding positions to move.
[0011] Based on the above technical solution, the transmission roller group and sub-drive assembly corresponding to the position of the feeding unit are designed such that when the pallet receives the fiber felt upward, the sub-drive assembly drives the pallet and the first conveyor belt to move at the same linear speed.
[0012] Based on the above technical solution, the drive unit is also designed such that after the pallet receives the fiber felt from the first conveyor belt, the drive unit drives the pallet to accelerate its displacement through the transmission roller group at the corresponding position; when the pallet approaches the first conveyor belt and before receiving the fiber felt, the drive unit drives the pallet to decelerate its displacement through the transmission roller group at the corresponding position, so that the pallet and the first conveyor belt move at the same linear speed.
[0013] Based on the above technical solution, a flipping drive is also included, which can drive the end of the first conveyor belt to adjust its pitch to move closer to or away from the pallet.
[0014] Based on the above technical solution, the surface of the first conveyor belt that contacts the fiber felt is provided with an anti-slip layer, and the top and bottom surfaces of the pallet are provided with the anti-slip layer.
[0015] Based on the above technical solution, the bracket includes a first length segment, a second length segment, a third length segment, and a fourth length segment arranged in a closed loop on the same plane. The first length segment is positioned close to the first conveyor belt, is coaxial with the first conveyor belt, and is parallel to the third length segment. The two ends of the second length segment are respectively connected to the first and third length segments, and the connection between the two ends of the second length segment and the first and third length segments forms a first transition segment. The two ends of the fourth length segment are respectively connected to the tail ends of the first and third length segments, and the connection between the two ends of the fourth length segment and the first and third length segments forms a second transition segment. The second transition segment connecting the first and fourth length segments includes a first drive roller group and a second drive roller group. The first drive roller group includes several first drive rollers for transferring the pallet along the axis of the first length segment to the next workstation. The second drive roller group includes several second drive rollers for transferring the pallet to the fourth length segment. The several first drive rollers are arranged at intervals, and the several second drive rollers are arranged at intervals.
[0016] Based on the above technical solution, it also includes a first lifting drive and a second lifting drive. The bracket includes a fifth length segment, a sixth length segment, a seventh length segment, and an eighth length segment arranged in a closed loop. The first end of the fifth length segment is located close to the first conveyor belt. The fifth length segment is coaxial with the first conveyor belt and arranged vertically parallel to the seventh length segment. The first lifting drive is located near the first ends of the fifth and seventh length segments and supports the eighth length segment upwards. The second lifting drive is located near the ends of the fifth and seventh length segments and supports the sixth length segment upwards.
[0017] Based on the above technical solution, the tray is further equipped with a first sensor group, a second sensor group, and a third sensor group. After the tray receives the fiber felt from the first conveyor belt, the first sensor group identifies the tray and sends a signal to the external controller. Before the tray receives the fiber felt, the second sensor group identifies the tray and sends a signal to the external controller. The third sensor group is used to identify the stacking height of the fiber felt on the tray in the fifth length section. When the stacking height of the fiber felt exceeds a set range value, the third sensor group sends a signal to the external controller to cause the tray to detach from the track assembly and be transported to the next workstation.
[0018] Beneficial effects
[0019] This invention features a rational structure. A pallet is positioned below the feeding unit to receive fiber felt, and above the track assembly. Under the action of the drive unit, the pallet moves along the track assembly. As the pallet moves along the loop of the track assembly, it can receive multiple layers of fiber felt to complete the fiber felt stacking. This allows it to be adapted to existing fiber felt production lines. With multiple pallets, continuous production can be achieved, significantly improving production efficiency. Furthermore, under the action of the drive unit, the pallet can detach from the track assembly and continue to be transferred to the next workstation, demonstrating good adaptability and seamless integration with existing fiber felt production lines. The track assembly includes a bracket with several drive rollers, which are further divided into multiple drive roller groups. This allows for flexible adjustment of the pallet's transfer speed on the track assembly, enabling rapid displacement during transfer and improving production efficiency. Simultaneously, it ensures that the pallet maintains the same linear speed as the first conveyor belt when receiving fiber felt, reducing the pulling or squeezing effects during fiber felt unloading and improving unloading accuracy.
[0020] The invention also includes a pitch adjustment mechanism for the feeding unit, which provides good flexibility and can be adapted to the production of multiple layers of fiber felt. On the other hand, it ensures that the pallet or the top surface of the stacked fiber felt always maintains a stable dropping height with the feeding unit, thereby ensuring a good dropping condition of the fiber felt and improving the stacking quality.
[0021] In this invention, the track assembly includes first to fourth length segments arranged in a closed loop, occupying little longitudinal space. When the pallet circulates multiple times along the first to fourth length segments, multiple fiber felts can be stacked, resulting in a high degree of automation and reduced labor costs. The availability of multiple pallets facilitates continuous production. The second transition segment connecting the first and fourth length segments includes a first and a second transmission roller group. Under the action of the drive unit, it can switch between continued circular transport of the pallet and detachment from the track assembly, further improving automation and facilitating continuous production. Alternatively, the track assembly includes fifth to eighth length segments arranged longitudinally and extending in a closed loop, occupying little planar space and facilitating arrangement. When the pallet circulates multiple times along the fifth to eighth length segments, multi-layer fiber felt stacking is achieved, resulting in a high degree of automation and reduced labor costs. The availability of multiple pallets facilitates continuous production. This invention also includes multiple sets of sensors to facilitate automated control. The first sensor set is used to identify whether the pallet has received all the fiber felt. The second sensor set is used to identify the distance between the fiber felt to be received and the first conveyor belt, so as to facilitate controlling the pallet to decelerate and move closer to the first conveyor belt. The third sensor set is used to identify whether the fiber felt on the pallet has reached the set number of stacking layers, so as to facilitate the transfer of fiber felt to the next process. The invention has a high degree of automation, facilitates the connection to the next process, and greatly improves production efficiency. Attached Figure Description

[0032] Example 1
[0033] like Figure 2 The present invention relates to a high-efficiency fiber felt stacking system, comprising a feeding unit 2, a pallet 1, a circulation unit and a controller.
[0034] The feeding unit 2 includes a first conveyor belt 21, a feeding drive roller, a feeding driven roller, and a feeding drive. The first conveyor belt 21 is sleeved on the feeding drive roller and the feeding driven roller. The roller shafts of the feeding drive roller and the feeding driven roller pass through the side plates 23 on both sides and are rotatably connected to the side plates 23. The feeding drive is fixed on the side plates 23 and transmits the rotational motion to the feeding drive roller. The first conveyor belt 21 is adapted to existing metal fiber felt production lines. Single-layer fiber felt is transported from the production line to the first conveyor belt 21. The fiber felt transported from the fiber felt production line to the first conveyor belt 21 has good left and right position accuracy. The first conveyor belt 21 transports the cut sheet fiber felt to the pallet 1.
[0035] It also includes a tilting drive. Each of the two side plates 23 has an outer vertical plate. A pin 22 passes through and is fixedly connected to each side plate 23, with both ends of the pin 22 rotatably connected to the vertical plate. Bearings are fitted at the rotatable connections. The tilting drive can rotate the pin 22, thereby causing the end of the first conveyor belt 21 to tilt closer to or further away from the pallet 1. This provides good flexibility, adaptable to the production of multiple layers of fiber felt, and ensures that the pallet 1 or the top surface of the stacked fiber felt always maintains a stable dropping height from the feeding unit 2, guaranteeing a good dropping condition for the fiber felt and thus improving the stacking quality.
[0036] Pallets 1, multiple pallets 1 are provided, pallets 1 are located below the feeding unit 2 to receive fiber felt; in this embodiment, the top and bottom surfaces of pallets 1 are provided with anti-slip layers, such as rubber pads, and the anti-slip layers are provided with anti-slip textures.
[0037] The circulation unit includes a track assembly 3 and a drive unit. The drive unit is electrically connected to the controller. The track assembly 3 supports the pallet 1 upward. The drive unit can drive the pallet 1 to move along the loop of the track assembly 3 so that the pallet 1 can receive fiber felt from the feeding unit 3 multiple times to complete the fiber felt stacking; or the drive unit can drive the pallet 1 to detach from the track assembly 3 so as to transfer the pallet 1 and the fiber felt to the next station.
[0038] Specifically, the track assembly 3 includes a bracket 31 and a plurality of drive rollers 32 disposed on the bracket 31. The bracket 31 is fixedly disposed, and the drive rollers 32 support the pallet 1 upward and drive the pallet 1 to move. The plurality of drive rollers 32 include multiple relatively independent drive roller groups, and the multiple drive rollers within a drive roller group are driven by a chain, such as... Figure 2 As shown; in this embodiment, the drive unit includes multiple independent sub-drive components, and each transmission roller group is powered by a sub-drive component.
[0039] In this embodiment, the bracket 31 includes a fifth length segment 315, a sixth length segment 316, a seventh length segment 317 and an eighth length segment 318 arranged in a closed loop. The first end of the fifth length segment 315 is located close to the first conveyor belt 21. The fifth length segment 315 is coaxial with the first conveyor belt 21 and arranged vertically parallel to the seventh length segment 317.
[0040] like Figure 2As shown, it also includes a first lifting drive 300 and a second lifting drive 400. The first lifting drive 300 is arranged near the beginning of the fifth length segment 315 and the seventh length segment 317. The first lifting drive 300 supports the eighth length segment 400 upwards, as shown in Figure 2. The first lifting drive 300 includes two first lifting cylinders. The two first lifting cylinders lift both ends of the eighth length segment 318 and act synchronously. When the eighth length segment 318 rises to the highest limit, the eighth length segment 318 is flush with the fifth length segment 315. When the eighth length segment 318 falls to the lowest limit, the eighth length segment 318 is flush with the seventh length segment 317. The second lifting drive 400 is arranged near the end of the fifth length segment 315 and the seventh length segment 317, and the second lifting drive 400 supports the sixth length segment 316 upwards, as shown in Figure 2. Figure 2 As shown, the second lifting drive 400 includes two second lifting cylinders. These two cylinders support both ends of the sixth length segment 316 and operate synchronously. When the sixth length segment 316 rises to its highest limit, it is aligned with the fifth length segment 315. When the sixth length segment 316 descends to its lowest limit, it is aligned with the seventh length segment 317. In this embodiment, the lifting of the eighth length segment 318 and the sixth length segment 316 is controlled by a set of limit switches. This set of limit switches is electrically connected to an external controller. The limit switches are existing technology and will not be described further here.
[0041] like Figure 2 As shown, when the first lifting drive 300 lifts the eighth length segment 318 to its highest limit and aligns it with the fifth length segment 315, the sub-drive component at the corresponding position activates to transport the pallet 1 from the eighth length segment 318 to the fifth length segment 315. After that, the first lifting drive 300 resets. In addition, the sub-drive component is also designed so that when the pallet passes under the first conveyor belt 21 and receives the fiber felt, the self-drive component drives the pallet 1 and the first conveyor belt 21 to move at the same linear speed. This can reduce the pulling or squeezing effect received by the fiber felt during the feeding process and help improve the feeding accuracy.
[0042] In this embodiment, the plurality of transmission rollers 32 include multiple transmission roller groups. The multiple transmission rollers 32 in a transmission roller group are driven by a chain. In addition, the drive unit includes multiple independent sub-drive components. Each transmission roller group is powered by a sub-drive component. This creates conditions for the pallet 1 to accelerate or decelerate along the track assembly 3. Specifically, the drive unit is designed such that when the pallet 1 receives the fiber felt from the first conveyor belt 21, the drive unit drives the pallet 1 to accelerate its displacement through the transmission roller group at the corresponding position; when the pallet 1 moves from the eighth length segment 318 to the fifth length segment 315, approaches the first conveyor belt 21, and before receiving the fiber felt, the drive unit drives the pallet 1 to decelerate its displacement through the transmission roller group at the corresponding position, so that the pallet 1 and the first conveyor belt 21 move at the same linear speed.
[0043] Thus, when the drive unit can drive the pallet 1 to move along the ring line of the track assembly 3, so that the pallet 1 can receive fiber felt from the feeding unit 2 multiple times to complete the fiber felt stacking; after the fiber felt stacking is completed, the second lifting drive 400 drives the sixth length section 316 to rise to the highest limit, and then the corresponding sub-drive assembly at the corresponding position moves to transfer the pallet 1 and the fiber felt on it to the next station, remove it from the track assembly 3, and then the second lifting drive 400 resets.
[0044] In this embodiment, there are multiple pallets 1, and multiple pallets 1 are transferred on the track assembly 3 at the same time. This not only adapts to the existing fiber felt production line, but also enables continuous production, which greatly improves production efficiency. In addition, when a pallet 1 is removed from the track assembly 3 and transferred to the next station, a new pallet 1 is replenished to the circulation assembly 3 by a worker or the loading unit, ensuring that there is always a fixed number of pallets 1 running on the circulation assembly 3 to maintain a stable production rhythm.
[0045] To facilitate automated control, the tray 31 is also equipped with a first sensor group, a second sensor group and a third sensor group. After the tray 1 receives the fiber felt from the first conveyor belt 21, the first sensor group identifies the tray and sends a signal to the external controller. The controller controls the transmission roller 32 in front of the tray 1 to rotate faster, so that the tray 1 moves forward faster.
[0046] When pallet 1 approaches the first conveyor belt 21 and receives fiber felt, the second sensor group identifies pallet 1 and sends a signal to the external controller. The controller controls the drive roller 32 in front of pallet 1 to decelerate and rotate, so that pallet 1 decelerates and moves forward. As a result, when pallet 1 receives fiber felt from the first conveyor belt 21, the first conveyor belt 21 and pallet 1 have the same linear speed.
[0047] In this embodiment, the third sensor group is used to identify the stacking height of the fiber felt on the pallet 1 at the end of the fifth length segment 315. When the stacking height of the fiber felt exceeds a set range value, the third sensor group sends a signal to the external controller to cause the pallet 1 to detach from the track assembly 3 and be transported to the next workstation. The first, second, and third sensor groups are existing technologies, and those skilled in the art can select them according to their needs; further details are omitted here.
[0048] like Figure 2 As shown, the conveying device for transferring the pallet 1 to the next workstation is located outside the bracket 31 and forms an extension section when the sixth length segment 316 is at its maximum limit. This allows the pallet 1 to be smoothly detached from the track assembly 3 and enter the next process, ensuring smooth production.
[0049] In this embodiment, the fiber felt stacking process is as follows:
[0050] A. The cut sheet fiber felt is conveyed forward by the feeding unit 2;
[0051] B. The drive unit drives the pallet 1 to move along the loop on the track assembly 3 to receive fiber felt multiple times and complete the fiber felt stacking. Specifically, as the fiber felt falls from the first conveyor belt 21 onto the pallet 1, the pallet 1 and the first conveyor belt 21 always have the same linear speed. After the pallet 1 finishes receiving the fiber felt, the drive unit accelerates the pallet 1 along the track assembly 3. When the pallet 1 moves from the end of the fifth length segment 315 to the sixth length segment 316, the second lifting drive 400 moves the sixth length segment 316 from the highest limit to the lowest limit, making the sixth length segment 316 flush with the seventh length segment 317; then it moves with the sixth length segment 316. The sub-drive component corresponding to the seventh length segment 317 moves, causing the pallet 1 to move from the sixth length segment 316 to the seventh length segment 317. Then, the pallet 1 continues to accelerate along the seventh length segment 317 and moves to the eighth length segment 318. At the same time, the second lifting drive 400 resets to the highest limit. Then, the first lifting drive 300 moves the eighth length segment 318 from the lowest limit to the highest limit, making the eighth length segment 318 flush with the fifth length segment 315. Then, the pallet 1 decelerates and moves at the same linear speed as the first conveyor belt 21. At the same time, the third lifting drive 300 resets to the lowest limit. This cycle repeats until the fiber felt is laid.
[0052] C. After the fiber felt is laid, the drive unit drives the pallet 1 to detach from the track assembly 3 and transport it to the next station. In this embodiment, after the limiting felt is laid, under the action of multiple sub-drive assemblies, the position of the pallet 1 and the fiber felt on it reaches the end of the fifth length segment 315 and then continues to move forward, so that the pallet 1 detaches from the track assembly 3 and is transported to the next station.
[0053] D When a pallet 1 is detached from the track assembly 3, an empty pallet 1 is added to the track assembly 3, and the empty pallet 1 is designed to replace the pallet 1 detached from the track assembly 3 for transport on the track assembly 3.
[0054] Example 2
[0055] The difference between Example 2 and Example 1 is that, as Figure 3 and 4As shown, the bracket 31 includes a first length segment 311, a second length segment 312, a third length segment 313, and a fourth length segment 314 arranged in a closed loop on the same plane. The first length segment 311 is located close to the first conveyor belt 21. The first length segment 311 is coaxial with the first conveyor belt 21 and parallel to the third length segment 313. The two ends of the second length segment 312 are connected to the first ends of the first length segment 311 and the third length segment 313, respectively. The connection between the two ends of the second length segment 312 and the first length segment 311 and the third length segment 313 forms a first transition segment 100, which extends along an arc or a broken line. The two ends of the fourth length segment 314 are connected to the tail ends of the first length segment 311 and the third length segment 313, respectively. The connection between the two ends of the fourth length segment 314 and the first length segment 311 and the third length segment 313 forms a second transition segment 200, which extends along an arc or a broken line.
[0056] The second transition section 200 connecting the first length segment 311 and the fourth length segment 314 includes a first transmission roller group and a second transmission roller group. The first transmission roller group includes several first transmission rollers 201 for transferring the pallet 1 along the axis of the first length segment 311 to the next work station. The second transmission roller group includes several second transmission rollers 202 for transferring the pallet 1 to the fourth length segment 314. The several first transmission rollers 201 are evenly spaced, and the several second transmission rollers 202 are evenly spaced, with the second transmission rollers 202 avoiding the first transmission rollers 201. In this embodiment, the first transmission rollers 201 extend uninterruptedly along their axis, and the corresponding second transmission rollers 202 include multiple length segments along their axial direction to avoid the first transmission rollers 201. In addition, the conveying device for transferring the pallet 1 to the next work station is located outside the bracket 31 and forms an extension of the first length segment 311. This allows the pallet 1 to be smoothly removed from the track assembly 3 and enter the next process, ensuring smooth production.
[0057] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
