Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a high-pollution metal fiber sintered felt gradient pore manufacturing device, including a transfer table 1 and a sintering device 2 fixedly connected to one end of the transfer table 1. Two support blocks 3 are fixedly connected to both sides of the transfer table 1. A guide rod 4 is welded to the inner wall of the support block 3. A plurality of gradient adjustment components 5 are arranged on the surface of the guide rod 4. Flattening components 6 are arranged on both sides of the surface of the transfer table 1;

[0023] The gradient adjustment component 5 includes a sliding ring 501, an adjustment bolt 502, an adjustment piece 503, a connecting rod 504, a material receiving frame 505, a servo motor 506, a blanking roller 507 and a timer 508. The surface of the guide rod 4 is slidably connected with the sliding ring 501. An adjustment hole is provided on the surface of the sliding ring 501. The adjustment bolt 502 is threadedly connected inside the adjustment hole. One end of the adjustment bolt 502 is fixedly connected with the adjustment piece 503. The connecting rod 504 is welded on the surface of the sliding ring 501. The top of the connecting rod 504 is welded with the material receiving frame 505. One side of the material receiving frame 505 is fixedly connected with the servo motor 506. The output end of the servo motor 506 is spline-connected with a transmission rod. One end of the transmission rod is fixedly connected with the blanking roller 507. The timer 508 is fixedly connected to the edge of one side of the material receiving frame 505. Through the settings of the sliding ring 501, the adjustment bolt 502, the adjustment piece 503, the connecting rod 504, the material receiving frame 505, the servo motor 506, the blanking roller 507 and the timer 508, during use, first place the metal fiber raw materials into the three material receiving frames 505 respectively. According to different manufacturing filtration purposes and different sizes of the metal fiber sintered felt to be made, it is necessary to adjust the gradient pores during the manufacturing process of the metal fiber sintered felt. First, turn the adjustment bolt 502 to move the sliding ring 501 so that the material receiving frames 505 are separated. Place the external felt mold on the transfer table 1. Then, a preset blanking time interval is set for each timer 508 on one side of the material receiving frame 505. When the preset time is reached, the programmable logic controller 7 controls the servo motors 506 to start respectively. In the order from right to left, the blanking rollers 507 are flipped to lay and stack the metal fiber raw materials. After being flattened, they are sent to the sintering device 2 for high-temperature heating and manufacturing, so as to achieve the manufacturing of the gradient pores of the high dirt-holding metal fiber sintered felt with different requirements. It avoids the situation that in the traditional metal fiber sintered felt, when adjusting the gradient pores, it is necessary to first sinter the rough blank, then sinter the fine blank, and then send this into the sintering device 2, resulting in a waste of a large amount of time, and improves the manufacturing efficiency of the gradient pores of the high dirt-holding metal fiber sintered felt and the adaptability of the manufacturing device.

[0024] Furthermore, a blanking port is provided on the inner bottom wall of the material receiving frame 505. The surface of the blanking roller 507 is symmetrically provided with a receiving groove. The blanking port is adapted to the receiving groove. Through the settings of the blanking port and the receiving groove, during use, when the blanking port and the receiving groove overlap, the metal fiber raw materials will fall onto the external felt mold, which plays a role in facilitating blanking.

[0025] Furthermore, a programmable logic controller 7 is fixedly connected to the edge of one side of the transfer table 1. The programmable logic controller 7 is electrically connected to the timer 508 through a power cord. Through the setting of the programmable logic controller 7, during use, according to the requirements of the gradient pores, the time settings of each timer 508 are different. When the set time is reached, the programmable logic controller 7 will control one of the servo motors 506 to start, flip the blanking roller 507, stack it, and lay it from right to left according to the transfer direction for pre-setting of the gradient pores;

[0026] Furthermore, the flattening assembly 6 includes a fixed block 601, a drive motor 602, and a pressing roller 603. Fixed blocks 601 are fixedly connected to both sides of the surface of the transfer table 1. A drive motor 602 is fixedly connected to one side of one of the fixed blocks 601. The output end is splined to a transmission rod, and one end of the transmission rod is fixedly connected to the pressing roller 603. Through the setting of the fixed block 601, the drive motor 602, and the pressing roller 603, during use, the transfer table 1 conveys the adjusted metal fiber raw material to the lower part of the pressing roller 603, presses the uneven metal fiber raw material flat, thereby achieving the compaction of the metal fiber raw material and forming a preliminary shape, improving the manufacturing quality of the high dirt-holding metal fiber sintered felt, avoiding the possible uneven pore structure or low sintering strength during the sintering process of the metal fiber, improving the manufacturing quality of the high dirt-holding metal fiber sintered felt, and saving costs;

[0027] Furthermore, a protective layer is fixedly connected to the surface of the pressing roller 603, and the length of the pressing roller 603 is adapted to the transfer width of the transfer table 1. Through the setting of the pressing roller 603, during use, the metal fiber raw material on the external felt mold conveyed is flattened to reduce unevenness;

[0028] Furthermore, a protective layer is coated on the surface of the guide rod 4, and the material of the protective layer is fluorocarbon. Through the setting of the guide rod 4, during use, the sliding ring 501 will slide on the surface of the guide rod 4, and scratches will appear after a long time. Fluorocarbon has a high hardness and can effectively resist physical wear and scratches, extending the service life of the guide rod 4;

[0029] Furthermore, support frames 8 are fixedly connected to the bottom ends of both the transfer table 1 and the sintering device 2. Installation pieces are fixedly connected to the bottom ends of the support frames 8. Through the setting of the support frames 8, during use, the high dirt-holding metal fiber sintered felt gradient pore manufacturing device is fixed to the ground through the installation pieces, and the support frames 8 play a role in stable support.

[0030] Working principle: First, the metal fiber raw materials are placed in three material holding frames 505 respectively. According to the different manufacturing filtering purposes and the different sizes of the metal fiber sintered felt, the gradient pores in the metal fiber sintered felt manufacturing process need to be adjusted. First, the adjustment bolt 502 is turned to move the sliding ring 501 to disperse the material holding frames 505, and the external felt mold is placed on the conveying table 1. Then, the timer 508 on one side of each material holding frame 505 is set to a predetermined material unloading time interval. When the predetermined time is reached, the programmable logic controller 7 controls the material unloading time interval. The servo motor 506 is started, and the unloading roller 507 is turned over from right to left to lay and stack the metal fiber raw material. The conveying platform then conveys the adjusted metal fiber raw material to the bottom of the pressing roller 603 to press the uneven metal fiber raw material flat. The external felt mold containing the compacted metal limiting raw material is then conveyed to the sintering device 2 for high-temperature heating and sintering. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
