Description

Technical Field

[0001] This utility model belongs to the field of filter material processing technology, and in particular relates to a roller press for metal sintered mesh. Background Technology

[0002] Metal sintered mesh is a new type of filter material made from multiple layers of woven metal wire mesh through special lamination, pressing, and vacuum sintering processes. It possesses high strength and overall rigidity. The mesh openings of each layer are interwoven, forming a uniform and ideal filter structure. This material overcomes the shortcomings of ordinary metal wire mesh, such as low strength and easy deformation of the mesh openings. Its overall performance is superior to ceramics and sintered metal powder materials. During the manufacturing process, metal sintered mesh requires roll forming to press the multiple layers of material into a single unit. However, the following drawbacks still exist in actual roll forming operations:

[0003] When rolling metal sintered mesh, multiple layers of material need to be rolled through rollers and other structures. During this process, the position when entering and leaving the roller gap may be inconsistent, resulting in deviation. This can easily lead to wrinkling or edge damage. The lack of corresponding guiding and correction functions makes it impossible to ensure stability during the rolling operation.

[0004] Secondly, before rolling, the sintered metal mesh is still in a multi-layered structure. The rolling process of the sintered metal mesh requires passing between two pressure rollers. The gap between the two pressure rollers has a certain height. If the unformed sintered metal mesh is not supported, it is easy for the sintered metal mesh to become loose during rolling, resulting in insufficient rolling and material displacement.

[0005] Secondly, for continuous production or high-pressure calendering, the surface of the pressure roller may heat up, and its thermal expansion may affect the rolling accuracy or damage the roller or metal sintered mesh.

[0006] Finally, calibrating the thickness is also important, especially when the sintered mesh requires a precise thickness. The roller press needs to be adjusted evenly to the target size. Too much pressure will damage the structure, while too little pressure will have no effect. It may be necessary to design a segmented or progressive pressure to continuously adjust the roller pressing thickness, that is, to change the gap between the rollers. Utility Model Content

[0007] The purpose of this utility model is to provide a rolling mill for sintered metal mesh. By setting up a base, support platform, limit strip, cooling box, driving roller, driven roller, and column, it solves the problems of possible position deviation during rolling of sintered metal mesh causing wrinkling or edge damage, loose material of each layer of sintered metal mesh during rolling, excessive distance from the rolling gap, possible temperature rise of the roller during continuous rolling affecting rolling accuracy or damaging the roller / sintered metal mesh, and the inability to adjust the rolling thickness.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a roller press for sintered metal mesh, including a base, a support platform, columns, a driven roller, a driving roller, and a cooling box. Two symmetrically distributed columns are fixed on the upper center line of the base. A driving roller is rotatably connected between the two columns. An I-shaped groove is opened inside the column above the driving roller. An I-shaped block is slidably arranged in the I-shaped groove. A driven roller is rotatably connected between the two I-shaped blocks.

[0010] A support platform is fixed above the base. Two symmetrical limiting strips are slidably arranged on the upper end of the support platform. Three equally spaced curved rods are fixed on the opposite sides of the two limiting strips. Screws are fixed on both sides of the support platform adjacent to the drive roller. Two symmetrically distributed stabilizing rods are also fixed on the side of the support platform outside the screws.

[0011] Cooling boxes are provided at positions away from the support platform outside both the driving roller and the driven roller, and semiconductor cooling chips are fixed inside the cooling boxes at equal intervals.

[0012] Furthermore, a mounting base is fixedly connected to the front side of the base, and a geared motor is fixedly connected to the upper end of the mounting base. The output shaft of the geared motor is connected to one end of the drive roller in a transmission connection.

[0013] Furthermore, the upper end of the support platform is lower than the highest point of the drive roller, and a limit ring is fixed to the end of all the bent rods away from the limit bar. The limit ring under the middle bent rod is threadedly connected to the screw, and the limit rings under the two bent rods on both sides are sleeved on the stabilizer rod below them.

[0014] Furthermore, the upper surface of the support platform is provided with three equally spaced limiting grooves, and the bottom surface of the limiting strip is fixed with three equally spaced limiting blocks, which are slidably disposed in the corresponding limiting grooves.

[0015] Furthermore, an adjusting rod is rotatably connected inside the I-beam slot, a servo motor is fixed at the upper end of the column, the upper end of the adjusting rod passes through the column and is connected to the output shaft of the servo motor, the portion of the adjusting rod located inside the I-beam slot is threaded, and the adjusting rod passes through the I-beam block and is threadedly connected to the I-beam block.

[0016] Furthermore, a fan is fixed to one end of the cooling box, and the air outlet of the fan is connected to the inside of the cooling box. The side of the cooling box facing the column is open, and the side of the cooling box with the opening is attached to the side of the column.

[0017] Furthermore, both ends of the cooling box are fixed with ear plates, and bolts are screwed through the ear plates, with the tail end of the bolts abutting against the adjacent column.

[0018] This utility model has the following beneficial effects:

[0019] This invention solves the problem of wrinkling or edge damage caused by potential misalignment during the rolling of sintered metal mesh by setting a base, support platform, and limiting strip. During the rolling process, the sintered metal mesh is laid on the support platform, and then the screw is rotated to move the limiting ring connected to it, thereby controlling the movement of the bending rod and driving the limiting strip to move until the limiting strip approaches the side of the sintered metal mesh. The other limiting strip is operated in the same way, thus restricting the rolling position of the sintered metal mesh. This design is suitable for rolling sintered metal meshes of various widths, while ensuring stability and preventing misalignment during the rolling process.

[0020] This invention solves the problem of loose material in each layer of the sintered metal mesh and excessive distance from the roll gap during roll forming by setting a support platform. The sintered metal mesh to be rolled is laid on the support platform, which is only slightly lower than the highest point of the drive roller. The roll gap is between the drive roller and the driven roller. The sintered metal mesh is rolled through this gap. Because the distance between the sintered metal mesh and the roll gap is small, there is no need to excessively lift the sintered metal mesh. This prevents the sintered metal mesh from warping or becoming loose, resulting in higher roll forming accuracy.

[0021] This invention solves the problem of rollers potentially overheating during continuous rolling, affecting rolling accuracy or damaging the rollers / metal sintered mesh. During continuous rolling, the driving and driven rollers may heat up due to contact with the metal sintered mesh, generating heat that could reduce rolling accuracy or damage the rollers and the metal sintered mesh. Therefore, a cooling box is installed outside the driving and driven rollers. The semiconductor cooling chip in the cooling box generates cold air, which is then blown onto the surfaces of the driving and driven rollers by a fan, rapidly cooling them and ensuring the efficiency of the continuous rolling process.

[0022] This invention solves the problem of unadjustable roll pressing thickness by setting up an active roller, a driven roller, and a column; two servo motors are connected to an external controller and work simultaneously to drive the adjusting rod to rotate, so that the I-beam block rises and falls synchronously in the I-beam groove, thereby changing the height position of the driven roller and changing the gap between the driven roller and the active roller, thus changing the thickness of the roll pressing.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] Please see Figure 1-7 As shown, this utility model is a roller press for metal sintered mesh, including a base 1, a support platform 2, columns 3, driven rollers 4, driving rollers 5 and a cooling box 6. Two symmetrically distributed columns 3 are fixed on the upper center line of the base 1. The driving rollers 5 are rotatably connected between the two columns 3. An I-shaped groove 302 is opened inside the column 3 above the driving rollers 5. I-shaped blocks 303 are slidably arranged in the I-shaped grooves 302. The driven rollers 4 are rotatably connected between the two I-shaped blocks 303.

[0035] The base 1 serves as the main carrier for processing. Two columns 3 are installed on top of it. Between the two columns 3, there is a rotating drive roller 5 and a driven roller 4. The height of the drive roller 5 is fixed, while the height of the driven roller 4 can be changed by moving the position of the I-beam block 303 in the I-beam groove 302, thereby changing the gap between the drive roller 5 and the driven roller 4.

[0036] A support platform 2 is fixedly installed above the base 1. Two symmetrical limiting strips 201 are slidably installed on the upper end of the support platform 2. Three equally spaced curved rods 202 are fixed on the opposite sides of the two limiting strips 201. Screws 204 are fixed on both sides of the support platform 2 adjacent to the drive roller 5. Two symmetrically distributed stabilizing rods 203 are also fixed on the side of the support platform 2 outside the screws 204.

[0037] The upper end of the support platform 2 is lower than the highest position of the drive roller 5. All the ends of the bent rods 202 away from the limiting strip 201 are fixed with limiting rings 2021. The limiting rings 2021 under the bent rod 202 in the middle are threadedly connected to the screw 204. The limiting rings 2021 under the two bent rods 202 on both sides are sleeved on the outside of the stabilizing rod 203 below them.

[0038] The upper surface of the support platform 2 is also provided with three equally spaced limiting grooves 205, and the bottom surface of the limiting strip 201 is fixed with three equally spaced limiting blocks 2011, and the limiting blocks 2011 are slidably disposed in the corresponding limiting grooves 205.

[0039] The support platform 2 is used to support the sintered metal mesh that needs to be rolled. Two limiting bars 201 are set above the support platform 2 to restrict the position of the sintered metal mesh, so that it remains stable during rolling and does not shift. During the movement of the limiting bars 201, the rotating screw 204 causes the middle bent rod 202 and the limiting ring 2021 to move (because the limiting bar 201 is restricted by the support platform 2 and the limiting groove 205 and cannot rotate). During the movement, the other two bent rods 202 and the limiting ring 2021 are sleeved on the outside of the stabilizing rod 203 to maintain the stability of the movement and prevent it from shifting. At the same time, the limiting block 2011 at the bottom of the limiting bar 201 is also restricted in the limiting groove 205, thereby ensuring the stable translation of the limiting bar 201, so that it can be adapted to the sintered metal mesh of different widths for correction and to maintain stability.

[0040] Cooling boxes 6 are provided at positions away from support platform 2 outside the drive roller 5 and driven roller 4, and semiconductor cooling chips 601 are fixed inside the cooling boxes 6 at equal intervals.

[0041] The cooling box 6 is used to cool the driving roller 5 and the driven roller 4. The semiconductor cooling chip 601 inside generates cold air and blows it onto the surface of the driving roller 5 and the driven roller 4 to cool them down.

[0042] A mounting base 101 is fixedly connected to the front side of the base 1, and a reduction motor 102 is fixedly connected to the upper end of the mounting base 101. The output shaft of the reduction motor 102 is connected to one end of the drive roller 5.

[0043] A geared motor 102 is installed using mounting base 101 to drive the active roller 5 to rotate. When the metal sintered mesh passes between the rotating active roller 5 and the driven roller 4, the metal sintered mesh is rolled and discharged. Under the action of friction, the driven roller 4 rotates in the opposite direction to discharge the metal sintered mesh.

[0044] An adjusting rod 304 is rotatably connected inside the I-beam slot 302. A servo motor 301 is fixed at the upper end of the column 3. The upper end of the adjusting rod 304 passes through the column 3 and is connected to the output shaft of the servo motor 301. The portion of the adjusting rod 304 located inside the I-beam slot 302 is threaded, and the adjusting rod 304 passes through the I-beam block 303 and is threadedly connected to the I-beam block 303.

[0045] Two servo motors 301 are connected to an external controller and work simultaneously to drive the adjusting rod 304 to rotate, so that the I-beam block 303 rises and falls synchronously in the I-beam groove 302, thereby changing the height position of the driven roller 4 and changing the gap between the driven roller 4 and the driving roller 5, that is, changing the thickness of the roll.

[0046] A fan 602 is fixed to one end of the cooling box 6, and the air outlet of the fan 602 is connected to the inside of the cooling box 6. The side of the cooling box 6 facing the column 3 is open, and the side of the cooling box 6 with the opening is attached to the side of the column 3.

[0047] The semiconductor cooling chip 601 in the cooling box 6 generates cold air, which is blown from the opening to the surfaces of the driving roller 5 and the driven roller 4 by the fan 602, so that they are cooled down quickly.

[0048] Both ends of the cooling box 6 are fixed with ear plates 603, and bolts 604 are screwed through the ear plates 603. The tail end of the bolts 604 abuts against the column 3 that is close to it.

[0049] When installing the cooling box 6, place it on the side of the drive roller 5 or driven roller 4 away from the support platform 2 and align it with the central axis of the corresponding roller. Then, the ear plate 603 overlaps the column 3. Rotate the bolt 604 to press against the column 3, and the ear plate 603 will move slightly outward, thereby restricting the position of the cooling box 6.

[0050] The specific working principle of this utility model is as follows: First, during the rolling of the sintered metal mesh, it is laid on the support platform 2. Then, the screw 204 is rotated to move the limiting ring 2021 connected to it, thereby controlling the movement of the bent rod 202. The other two bent rods 202 and the limiting ring 2021 are sleeved on the outside of the stabilizing rod 203 to maintain the stability of the movement and prevent deviation. At the same time, the limiting block 2011 at the bottom of the limiting strip 201 is also restricted in the limiting groove 205, thereby ensuring the stable translation of the limiting strip 201 and changing the distance between the two limiting strips 201 to correspond to the width of the sintered metal mesh, thus preventing the sintered metal mesh from moving out of the machine. After offsetting, two servo motors 301 are connected to an external controller and work simultaneously to drive the adjusting rod 304 to rotate, so that the I-beam block 303 rises and falls synchronously in the I-beam groove 302, thereby changing the height position of the driven roller 4, changing the gap between the driven roller 4 and the driving roller 5, and determining the thickness of the roll pressing. Then, the reduction motor 102 drives the driving roller 5 to rotate, slightly pushing the metal sintered mesh into the roll gap between the driving roller 5 and the driven roller 4. The driving roller 5 rotates, and when the metal sintered mesh passes between the rotating driving roller 5 and the driven roller 4, under the action of friction, the driven roller 4 rotates in the opposite direction, pressing the metal sintered mesh and then exporting it.

[0051] The cooling box 6 is installed beforehand and placed on the side of the drive roller 5 or driven roller 4 away from the support table 2, and aligned with the central axis of the corresponding roller. Then, the ear plate 603 is attached to the outside of the column 3. The bolt 604 is rotated to press against the column 3, and the ear plate 603 will move slightly outward, thereby restricting the position of the cooling box 6. During operation, the drive roller 5 and driven roller 4 may heat up due to contact with the metal sintered mesh during continuous rolling. The semiconductor cooling chip 601 in the cooling box 6 works to generate cold air, which is blown to the surface of the drive roller 5 and driven roller 4 by the fan 602 to cool them down quickly and ensure the efficiency of continuous rolling process.

[0052] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
