DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figure 1 and 2 As shown in Figures 3 and 5, a cold rolling pretreatment device for metal plates includes a support frame 1. One side of the top of the support frame 1 is fixedly connected with a fixed frame 2, and a support plate 3 is installed on one side. A sleeve 4 is installed on the bottom side of the support plate 3. A spring 5 is fixedly connected to the inner wall of the sleeve 4. One end of the spring 5 is fixedly connected with a movable rod 6. One end of the movable rod 6 penetrates and extends to the bottom side of the sleeve 4 and is fixedly connected with a mounting frame 7. A rotating shaft 8 is rotatably installed between the two sides of the mounting frame 7. An auxiliary roller 9 is installed on the outer wall of the rotating shaft 8. An electrode plate 10 is installed on the outer wall of the top end of the movable rod 6. A chute 11 is opened inside the sleeve 4. An electrode plate 12 is installed inside the chute 11. A dust collection box 24 is installed inside the bottom side of the support frame 1 on one side of the auxiliary roller 9. A blower 25 is installed through one side of the dust collection box 24. A filter plate 26 is installed on the inner wall of the dust collection box 24. A conveying pipe 27 is installed on the top side of the dust collection box 24. The top end of the conveying pipe 27 is connected with a dust suction hood 28. The dust suction hood 28 is arranged in a "square" shape. A number of dust suction holes 29 are equidistantly opened on the inner wall of the dust suction hood 28. A control panel 30 is installed on one side of the support frame 1. During operation, in practical applications, during production breaks or when the supply of metal plates is discontinuous, the blower 25 keeps running, and it is impossible to automatically control the blower 25, which will consume unnecessary electrical energy and cause waste of energy. When the metal plate enters the pretreatment device, the metal plate will contact and push the auxiliary roller 9 upward, causing the movable rod 6 to move upward along the sleeve 4 and compress the spring 5. The electrode plate 10 also moves upward accordingly, contacts the outer arc surface of the electrode plate 12 and generates an electrical signal, and transmits this signal to the control panel 30. The control panel 30 controls the blower 25 to start, so that the dust and impurities on the surface of the metal plate enter the dust suction hood 28 through the dust suction holes 29 under the suction force, and then are sucked into the dust collection box 24 through the conveying pipe 27. The filter plate 26 will block and collect the dust and impurities, thereby realizing the dust cleaning treatment on the surface of the metal plate to ensure the cleanliness of the surface of the metal plate before cold rolling. When the conveyance of the metal plate ends, the auxiliary roller 9 is no longer under pressure, the electrode plate 10 is separated from the electrode plate 12, and the blower 25 stops working, realizing the automatic control of the start of the blower 25 and effectively reducing energy consumption.

[0024] Please refer to Figures 1-5As shown in the figure, two rotating shafts 13 are symmetrically and rotatably installed through the two sides of the support frame 1. A rotating roller 14 is installed on the outer wall of the rotating shaft 13. One end of the rotating shaft 13 is respectively installed with a driving wheel 15 and a driven wheel 16, and the driving wheel 15 and the driven wheel 16 are drivingly connected through a belt 17. One side of the support frame 1 is installed with a conveying motor 18, and one end of the rotating shaft 13 is connected with the output end of the conveying motor 18. Three support rollers 19 are equidistantly installed between the two rotating rollers 14 on both sides of the support frame 1 through a connecting shaft. Three support rollers 19 are equidistantly installed between the two sides of the support frame 1 through a connecting shaft. During operation, in the pre-treatment process of the metal plate, in order to ensure the continuous processing operation of the metal plate, start the conveying motor 18, and its output end drives the rotating shaft 13 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate through the belt 17, so that the rotating shaft 13 where the driven wheel 16 is located also rotates accordingly, and the rotating roller 14 rotates synchronously, thereby providing power for the forward conveying of the metal plate. During the conveying process of the metal plate, the support roller 19 can ensure that the metal plate remains flat during the conveying process and improve the processing efficiency of the metal plate.

[0025] Please refer to Figure 1 , 2 , 4, and 5, one side of the fixed frame 2 is installed with a servo motor 20, and the output end of the servo motor 20 is installed with a bidirectional lead screw 21. One end of the bidirectional lead screw 21 penetrates through the fixed frame 2 and is rotatably installed on the inner wall of one side thereof. A guide rod 22 is fixedly connected between the two sides of the fixed frame 2, and limit plates 23 are installed on the outer walls of both ends of the guide rod 22 and the bidirectional lead screw 21 in a matching manner. During operation, in practical applications, in order to prevent the sheet material from running off during the conveying process, it is necessary to start the servo motor 20 according to the width of the metal plate, and its output end drives the bidirectional lead screw 21 to rotate. Due to the limitation of the guide rod 22, it makes a linear motion along the bidirectional lead screw 21 and the guide rod 22. As the bidirectional lead screw 21 rotates, the limit plates 23 at both ends will move closer to the middle or move away from each other at the same time, so that the distance between the limit plates 23 can be adjusted according to the metal plate to ensure the stability during the conveying process.

[0026] Working principle: Start the servo motor 20, and its output end drives the bidirectional lead screw 21 to rotate. Due to the limitation of the guide rod 22, it makes a linear motion along the bidirectional lead screw 21 and the guide rod 22. As the bidirectional lead screw 21 rotates, the limit plates 23 at both ends will move closer to the middle or move away from each other at the same time, so that the distance between the limit plates 23 can be adjusted according to the metal plate to ensure the stability during the conveying process;

[0027] When the metal plate enters the pretreatment device, the metal plate contacts and pushes the auxiliary roller 9 upward, causing the movable rod 6 to move upward along the sleeve 4 and compress the spring 5. The electrode piece 10 also moves upward accordingly, contacts the outer arc surface of the electrode plate 12 and generates an electrical signal. The control panel 30 controls the blower 25 to start, so that the dust and impurities on the surface of the metal plate enter the dust suction hood 28 through the dust suction holes 29 under the action of suction, and then are sucked into the dust collection box 24 through the conveying pipe 27. The filter plate 26 blocks and collects the dust and impurities, thereby realizing the dust cleaning treatment of the metal plate surface to ensure the cleanliness of the metal plate surface before cold rolling. When the conveyance of the metal plate ends, the auxiliary roller 9 is no longer under pressure, the electrode piece 10 is separated from the electrode plate 12, and the blower 25 stops working, realizing the automatic control of the start of the blower 25 and effectively reducing energy consumption;

[0028] Start the conveying motor 18, the output end of which drives the rotating shaft 13 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate through the belt 17, so that the rotating shaft 13 where the driven wheel 16 is located also rotates accordingly, making the rotating roller 14 rotate synchronously, thereby providing power for the forward conveyance of the metal plate. During the conveyance of the metal plate, the supporting roller 19 can ensure that the metal plate remains flat during conveyance and improve the efficiency of processing the metal plate.
