[0047] A dust suction port 5331 is provided on the side of the two clamping plates 533 close to each other, and a dust suction cavity 5332 connected to the dust suction port 5331 is provided inside the clamping plates 533, and one end of the dust suction member 54 is connected to the dust suction cavity 5332;

[0048] The dust collecting component 54 includes a fixed tube 541, a connecting hose 542, a dust collecting box 543 and a vacuum pump 544. Two fixed tubes 541 are provided. One end of the two fixed tubes 541 is connected to the two dust collecting chambers 5332 respectively, one end of the fixed tube 541 away from the dust collecting chamber 5332 is connected to the connecting hose 542, and the close ends of the two connecting hoses 542 are connected to the dust collecting box 543. The input end of the vacuum pump 544 is connected to the dust collecting box 543.

[0049] Specific implementation process: When the bent steel plate is introduced to the support platform 4 through multiple conveying rollers 31, the two moving screws 51 keep rotating synchronously under the operation of the synchronization member 55 and the driving member 56. When the moving screws 51 rotate, they provide driving force to the moving blocks 52 thereon respectively. Since the moving blocks 52 are limited by the moving grooves 42, the two moving blocks 52 drive the clamping plates 533 to move along the steel plate until the two clamping plates 533 move to the steel plate. On both sides of the plate, the two electric push rods 531 operate respectively, so that the two clamping plates 533 clamp and fix the steel plate to each other, and then clamp the steel plate to the support platform 4, and then the vacuum pump 544 operates to generate negative pressure at the dust box 543, and then through the two connecting hoses 542 and the two fixing pipes 541, a negative pressure is formed at the dust suction cavity 5332 at the clamping plate 533 and the dust suction port 5331, so as to achieve the effect of adsorbing particulate impurities and debris on the surface of the steel plate;

[0050] See also Figures 6 to 9 The tail end of the support platform 4 is fixedly connected with an air inlet shell 9, and the bottom end of the air inlet shell 9 is connected with a second blower 91.

[0052] Specific implementation process: When the bent steel plate is clamped to the top of the support platform 4 by the two clamping plates 533, the second blower 91 is operated to guide the airflow through the dust removal port 931, and the guided airflow is used to scrape off the particulate impurities and debris on the lower surface of the bent steel plate. At the same time, in the present invention, the top of the air outlet hood 93 is set in a conical shape, so that when the steel plate moves relative to the air outlet hood 93, the particulate impurities and debris at the bottom of the steel plate can be scraped off simultaneously. At the same time, since the movable rubber plug 94 at the bottom of the air outlet hood 93 is connected to the air inlet shell 9 through the buffer spring 95, when the bent steel plate moves, the air outlet hood 93 can be supported by multiple buffer springs 95 and can move and retract relative to the bent steel plate to achieve the scraping effect.

[0053] See also Figures 1 to 3 and Figures 10 to 12A reset mechanism 6 is provided above the steel plate introduction limiter 5, and the return mechanism is used to reset the bent steel plate so that the bent steel plate can be flattened and then enter the roller assembly 2 for rolling; the reset mechanism 6 includes a fixed frame 61, a reciprocating member 7 and a rolling flattening member 8, the fixed frame 61 is located outside the support platform 4, the reciprocating member 7 is installed on the top of the fixed frame 61, and the reciprocating member 7 is located directly above the support platform 4, and two rolling flattening members 8 are provided, and the two rolling flattening members 8 are connected to the reciprocating member 7;

[0054] The reciprocating member 7 includes a bidirectional threaded screw 71 and a drive motor 72. The bidirectional threaded screw 71 is rotatably connected to the top of the fixed frame 61. The drive motor 72 is fixedly installed on one side of the fixed frame 61, and the drive motor 72 is used to drive the bidirectional threaded screw 71.

[0055] The roller-leveling member 8 includes a connecting plate 81, a connecting block 82, a guide frame 83 and a leveling roller 84. The connecting plate 81 is U-shaped, and the connecting plate 81 is threadedly sleeved on the outside of the bidirectional threaded screw 71. The connecting plate 81 is slidably connected to the fixed frame 61. The bottom of the connecting plate 81 is two connecting ends 811. A connecting port 821 is provided inside the connecting block 82, and the bottom of the connecting end 811 slides through the connecting port 821, that is, the connecting end 811 slides through the connecting port 821, and the connecting end 811 cooperates with the connecting port 821. An introduction hole 812 is provided at the connecting end 811, and the introduction holes 812 at the tops of the two connecting ends 811 are connected to each other with an introduction pipe 85, one end of the introduction pipe 85 is connected to a telescopic pipe 86, and one end of the telescopic pipe 86 is connected to a first blower 87, and the first blower 87 is fixedly installed on the support frame 3;

An oblique opening 832 communicating with the air guide groove 831 is provided at the bottom of the guide frame 83 away from the leveling roller 84.

[0058] The four connecting blocks 82 are provided with synchronous grooves 822 on the sides close to each other, and synchronous plates 823 are slidably connected to each other in the four synchronous grooves 822. Synchronous ports are provided on the fixed frame 61 at positions corresponding to the two synchronous plates 823, and the synchronous plates 823 slide through the synchronous ports. A pushing block 824 is fixedly connected to one end of the synchronous plate 823 located outside one of the synchronous ports, and a pushing cylinder 825 for pushing the pushing block 824 is installed on the fixed frame 61;

[0059] Specific implementation process: when the bent steel plate moves to the top of the support platform 4 through the two clamping plates 533, the cylinder 825 is pushed to operate, thereby driving the four connecting blocks 82 to move down through the synchronization plate 823, until the two leveling rollers 84 at the bottom of the four connecting blocks 82 move down to the upper surface of the bent steel plate and contact the bent steel plate. Then, on the one hand, the driving motor 72 is operated to rotate the bidirectional threaded screw 71, and when the bidirectional threaded screw 71 rotates, it provides driving force in opposite directions to the two connecting plates 81 respectively. Due to the limiting effect of the fixed frame 61, the connecting plate 81 pushes the connecting block 82 to move along the edge of the bent steel plate through the two connecting ends 811 at its bottom. At the same time, the leveling roller 84 rolls relative to the upper surface of the bent steel plate. The two leveling rollers 84 move in directions away from and toward each other, thereby achieving the effect of reciprocating rolling and leveling the bent steel plate. At this time, the first blower 87 is running, so that the airflow enters the air outlet through the telescopic tube 86, the inlet tube 85, and the inlet hole 812, and then enters the air guide groove 831 through the two air outlets, and is discharged through the inclined port 832, so that the impurity particles and debris on the upper surface of the steel plate are blown into the dust suction port 5331 through the airflow, so that the surface of the steel plate is fully dusted.

[0060] Embodiment 2

When the first rotating gear 561 rotates, the moving screw rod 51 on its inner ring is driven to rotate. Since the two moving screw rods 51 are synchronously driven by the synchronous gear 551 and the gear chain 552, the two moving screw rods 51 further rotate synchronously relative to the moving groove 42.
