Description

Technical Field

[0001] This utility model relates to the field of sieve plate processing technology, specifically a sieve flattening device for processing stainless steel sieve plates. Background Technology

[0002] Screen plates, also known as perforated plates, have good wear resistance, long service life, and good moisture resistance. They are suitable for mechanical industries such as ore washing, screening, grading, slag removal, desliming, and dewatering.

[0003] Publication No. CN216324287U discloses a rapid flattening device for stainless steel sieve plate processing. This patent, through the design of a drive cylinder, connecting plate, flattening device, and connecting frame, allows the drive cylinder to move the connecting frame and flattening device downwards, causing the connecting frame to press the sieve on the worktable, preventing the sieve from shifting and thus improving the efficiency of sieve flattening. A limiting block at the bottom of the connecting frame allows the limiting block to contact the sieve, enabling protrusions on the limiting block to engage with the sieve holes, further pressing the sieve and effectively preventing misalignment. However, this patent still has the following problems in practical use:

[0004] By setting a limiting block at the bottom of the connecting frame, the limiting block can contact the screen, allowing the protrusion on the limiting block to engage with the screen holes on the screen, effectively preventing screen misalignment. However, in actual use, the screen is curved. During the flattening process, the screen will change from curved to straight. If the screen is fixed, it will be difficult for it to deform further during the straightening process. Subsequent flattening work can easily damage the screen, making it inconvenient for subsequent use. Furthermore, during the deformation process, the two ends of the screen are prone to friction with the pressure plate or worktable, and the curved ends of the screen are easily damaged after being subjected to friction.

[0005] A screen flattening device for processing stainless steel screen plates is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a screen flattening device for processing stainless steel screen plates, in order to solve the problem mentioned in the background art. Currently, the limiting block is set at the bottom of the connecting frame so that the limiting block can contact the screen and the protrusion on the limiting block can be locked into the screen holes on the screen, which can effectively prevent the screen from being misaligned. However, in actual use, the screen is curved. During the flattening process, the screen will change from curved to straight. If the screen is fixed, it is difficult for the screen to deform again during the gradual straightening process. The subsequent flattening work is prone to damage to the screen, which is inconvenient for the subsequent use of the screen. In addition, during the deformation process, the two ends of the screen are prone to friction with the pressure plate or worktable. The curved ends of the screen are prone to damage after being rubbed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a screen flattening device for processing stainless steel screen plates, including a worktable;

A movable plate is fixedly installed on the movable end of the hydraulic cylinder. Two sets of guide rods are symmetrically slidably connected inside the movable plate. The two ends of the two sets of guide rods are fixedly connected to the fixed frame and the workbench, respectively. A pressing component is provided on the top of the movable plate.

[0011] The pressing component includes two sets of fixed blocks symmetrically installed on the top of the movable plate, and a positioning frame is fixedly installed between the two fixed blocks in each set. A movable frame is slidably connected to the outside of the two positioning frames on each side, and a fixed rod is symmetrically installed on the top of the movable frame.

[0012] The two fixed rods are slidably connected to a movable plate, and each of the two fixed rods is fitted with a telescopic spring below the movable plate. The two ends of the telescopic spring are fixedly connected to the movable plate and the movable frame, respectively.

[0013] Preferably, two sets of mounting brackets are symmetrically installed on the bottom of each of the two movable plates, and a roller is rotatably connected between the two mounting brackets in each set. Furthermore, through slots are symmetrically opened on the top of each movable plate below the two movable plates.

[0014] Preferably, an adjusting frame is fixedly installed on the side of each of the two movable frames that are close to each other, and a rotating gear is rotatably connected to the lower outside of the movable end of the hydraulic cylinder. A toothed plate is fixedly installed on the side of each of the two adjusting frames that are close to each other, and both toothed plates are meshed with the rotating gear.

[0015] Preferably, a positioning block is slidably connected to one side of each of the two adjustment frames, and the positioning block is fixedly connected to the movable plate. A positioning pin is inserted into the inside of one positioning block, and a number of positioning holes are opened through the front of one adjustment frame, and the positioning pin is adapted to the positioning holes.

[0016] Preferably, mounting blocks are symmetrically installed on one side of the positioning block, and positioning rods are slidably connected inside both mounting blocks. An annular groove is provided on the outer side of the positioning pin, and the positioning rod is engaged with the annular groove.

[0017] Preferably, a return spring is sleeved on the outer side of each of the two positioning rods, and one end of the return spring is fixedly connected to the mounting block, and the other end of the return spring is fixedly installed with a connecting block, and the connecting block is fixedly connected to the positioning rod.

[0018] Preferably, a limiting rod is fixedly installed on one side of each of the two mounting blocks, and a movable ring is slidably connected to the outside of the two limiting rods. Connecting rods are symmetrically hinged on both sides of the movable rings, and the ends of the two connecting rods away from the movable rings are respectively hinged to the two connecting blocks.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This stainless steel sieve plate processing sieve flattening device allows the warped ends of the sieve to be pressed down and deformed during sieve flattening, avoiding unnecessary friction and damage to the sieve during subsequent pressing, thus improving practicality. The specific details are as follows:

[0020] 1. When flattening the screen, place it on top of the workbench with the curved end facing upwards. Then, control the hydraulic cylinder to move the movable plate downwards. During the downward movement of the movable plate, the two sets of rollers first contact the screen. As the movable plate continues to move downwards, the rollers press down on the screen. At this point, the rollers position the screen to prevent movement. The movable plate then moves downwards, causing the rollers to gradually flatten the screen. The downward movement of the movable plate also moves the mounting bracket, which in turn moves the movable plate. This causes the movable plate to slide on the fixed rod and stretch the telescopic spring, causing the rollers to... The rollers can retract into the through groove, and then the entire movable plate comes into contact with the screen to flatten it. Before the movable plate flattens the screen, the two sets of rollers can flatten the curved ends of the screen, preventing the screen from bending too much when the movable plate flattens it. This would cause excessive friction between the screen and the movable plate during the deformation process. The pressing component can press down the raised ends of the screen to deform it when flattening it, avoiding unnecessary friction and damage to the screen during the subsequent pressing process, thus improving its practicality.

[0021] 2. Before flattening the screen, place the screen on the worktable. The movable ring can be moved according to the position of the curved end of the screen. The movable ring's movement causes the connecting rod to rotate. This rotation of the connecting rod causes the connecting block and positioning rod to move together, stretching the return spring and disengaging the positioning rod from the annular groove on the positioning pin. This removes the positioning pin from its limit position, allowing it to be removed. Then, one side of the moving plate can be moved, allowing the movable frame to slide on the positioning frame, thus moving the adjusting frame. The movement of one side of the adjusting frame drives the rotating gear through a toothed plate. This rotating gear, by meshing with the other toothed plate, moves the other side of the adjusting frame. The movement allows the two movable plates to move closer or further apart simultaneously, facilitating the simultaneous adjustment of the positions of the two sets of rollers. After adjustment, the positioning pin is passed through the corresponding positioning hole and positioning block. One end of the positioning pin is equipped with a ramp, allowing the positioning pin to move by pushing the positioning rod through the ramp. This causes the return spring to deform, and the movement of the positioning pin aligns the annular groove with the positioning rod. Then, under the action of the return spring, the positioning rod returns to its original position and inserts into the annular groove, thus positioning the positioning pin and consequently the adjusting frame. This allows workers to easily adjust the positions of the two sets of rollers according to the bending position of the screen, reducing the possibility of friction between the bent ends of the screen and the movable plate, and improving convenience and practicality.

[0030] Two sets of mounting brackets 207 are symmetrically installed on the bottom of each of the two movable plates 206, and rollers 209 are rotatably connected between the two mounting brackets 207 in each set. The top of the movable plate 104, located below the two movable plates 206, has symmetrical through slots 208 that allow the rollers 209 to straighten the bent ends of the screen. Adjusting brackets 210 are fixedly installed on the adjacent sides of the two movable brackets 203, and rotating gears 212 are rotatably connected to the lower outer side of the movable end of the hydraulic cylinder 103. The two adjusting brackets 210 are also adjacent to each other. A toothed plate 213 is fixedly installed on one side, and both toothed plates 213 are meshed with a rotating gear 212, allowing the two moving plates 206 to move closer or further away simultaneously. A positioning block 211 is slidably connected to the outer side of each of the two adjusting frames 210, and the positioning block 211 is fixedly connected to the movable plate 104. A positioning pin 214 is inserted into the interior of one positioning block 211, and several positioning holes 215 are formed through the front of one adjusting frame 210.

[0031] Working principle: Before using this type of stainless steel sieve plate processing screen flattening device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, when flattening the screen, the screen is placed on top of the workbench 1 with the curved end facing upwards. Then, the hydraulic cylinder 103 can be controlled to move the movable plate 104 downwards. During the downward movement of the movable plate 104, the two sets of rollers 209 first contact the screen. Then, as the movable plate 104 continues to move downwards, the rollers 209 press down on the screen. At this time, the rollers 209 can position the screen and prevent it from moving. Afterwards, the downward movement of the movable plate 104, through the rollers 209, gradually makes the screen tend to be straight. The downward movement of the movable plate 104 can move the mounting bracket 207, which can drive the movable plate 206 to move, causing the movable plate 206 to slide and stretch on the fixed rod 204. The telescopic spring 205 allows the rollers 209 to retract into the through groove 208, after which the movable plate 104 comes into contact with the screen, flattening the screen. Before the movable plate 104 flattens the screen, the two sets of rollers 209 can flatten the curved ends of the screen, preventing the screen from bending too much when the movable plate 104 flattens the screen, which would cause excessive friction between the screen and the movable plate 104 during the deformation process. The pressing component 2 can press down the raised ends of the screen to deform it when flattening the screen, avoiding unnecessary friction during the pressing process and preventing damage to the screen, thus improving practicality.

[0032] Before flattening the screen, the screen is placed on the workbench 1. The movable ring 222 can be moved according to the position of the curved end of the screen. After the movable ring 222 moves, it can drive the connecting rod 223 to rotate. When the connecting rod 223 rotates, it can drive the connecting block 220 and the positioning rod 217 to move together, which can stretch the return spring 219 and make the positioning rod 217 disengage from the annular groove 218 on the positioning pin 214, so that the positioning pin 214 loses its limit and can be removed. Then, one side of the moving plate 206 can be moved, so that the movable frame 203 slides on the positioning frame 202, which can drive the adjusting frame 210 to move. After the adjusting frame 210 moves, it drives the rotating gear 212 to rotate through the toothed plate 213 on one side. After the rotating gear 212 rotates, it can drive the other side of the adjusting frame by meshing with the toothed plate 213 on the other side. The movement of 210 allows the two movable plates 206 to move closer or further apart simultaneously, facilitating the simultaneous adjustment of the positions of the two sets of rollers 209. After adjustment, the positioning pin 214 passes through the corresponding positioning hole 215 and positioning block 211. One end of the positioning pin 214 is provided with a ramp, allowing the positioning pin 214 to move by pushing the positioning rod 217 through the ramp, causing the return spring 219 to deform. The movement of the positioning pin 214 aligns the annular groove 218 with the positioning rod 217. Then, under the action of the return spring 219, the positioning rod 217 is reset and inserted into the annular groove 218, which can position the positioning pin 214 and thus position the adjusting frame 210. This allows the operator to adjust the positions of the two sets of rollers 209 according to the bending position of the screen, reducing the possibility of friction between the bent ends of the screen and the movable plate 104, and improving convenience and practicality.
