Description

Technical Field

[0001] The invention relates to the technical field of cold rolling equipment, and in particular to a container processing high-speed cold rolling mill. Background Art

[0002] In the field of steel surface extrusion technology, especially in the container manufacturing industry, the processing of steel plate surface is a key step. Traditionally, steel plates for container surfaces are mostly rolled using cold rolling mills. This process uses two symmetrical rolling wheels to feed the steel plate into the rolling wheels, so that it is formed under the rolling and extrusion of the upper and lower rolling wheels. This method can quickly process steel plates for container surfaces.

[0003] Chinese patent application CN118080580B discloses a container processing high-speed cold rolling mill. During cold rolling, the steel to be processed is placed between the rotating rolling roller and the lower support roller, and the steel after cold rolling is fed to the surface of the extension platform. As the feeding continues, the end of the cold rolled steel covers the surface of the stress relief mechanism to prevent the steel being cold rolled from being affected. At the same time, with the help of the stress relief component, the steel can be fully stress relieved.

[0004] However, when faced with steel plates of varying widths, the above scheme lacks a corresponding adjustment mechanism to ensure the stability of the steel plates during transportation, causing the steel plates to easily shift during the cold rolling process. This shift not only causes uneven rolling on the surface of the steel plates, but may also cause defects such as wrinkles and cracks on the steel plates during the cold rolling process, seriously affecting the quality of the finished container products.

[0005] Therefore, it is an urgent problem to be solved by the present invention to provide a container processing high-speed cold rolling mill that can automatically adjust according to steel plates of different widths during use to ensure the stability and accuracy of the steel plates during transportation and rolling.

DETAILED DESCRIPTION

[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0039] Reference Figure 1-Figure 8 As shown, a container processing high-speed cold rolling mill comprises: an unwinding roller 101 fixedly mounted on a base 100 and a plurality of groups of cold rolling mechanisms 400 arranged at intervals, a first bracket 103 is fixedly provided on the base 100 at the rear of the unwinding roller 101, a support roller 104 is rotatably provided in the first bracket 103, a stress relief part 102 is fixedly provided on the base 100 at the rear of the cold rolling mechanism 400; wherein, a left and right limiting mechanism 200 for limiting the position of steel plates of different widths is provided on the first bracket 103, and a cleaning mechanism 300 for cleaning the upper and lower surfaces of steel plates of different thicknesses is fixedly provided on the base 100 between the left and right limiting mechanisms 200 and the cold rolling mechanism 400 with adjustable spacing.

[0040] When in use, the steel plate to be processed is placed on the unwinding roller 101, and the unwinding roller 101 starts to rotate, gradually releasing the steel plate. After passing through the unwinding roller 101, the steel plate enters the support roller 104 in the first bracket 103. At this time, the left and right limit mechanisms 200 are adjusted according to the width of the steel plate to ensure that the steel plate will not deviate left and right during the transmission process and maintain a stable transmission path. The cleaning mechanism 300 adjusts the spacing between the upper and lower cleaning components according to the thickness of the steel plate, cleans the upper and lower surfaces of the steel plate, removes impurities and oil stains on the steel plate, and the steel plate continues to be transmitted forward and enters the multiple groups of cold rolling mechanisms 400 for cold rolling. The cold rolling mechanism 400 presses the steel plate to achieve the required thickness and hardness. Finally, the steel plate passes through the stress relief member 102 to eliminate the internal stress generated by the steel plate during the cold rolling process, thereby improving the stability and service life of the steel plate. The left and right limit mechanisms 200 can be adjusted according to steel plates of different widths to ensure that the steel plates remain stable during transmission, thereby improving the accuracy of cold rolling processing. The cleaning mechanism 300 can adjust the spacing between the upper and lower cleaning components according to the thickness of the steel plates, so that the cold rolling mill can process steel plates of different thicknesses, thereby enhancing the adaptability and flexibility of the equipment.

[0041] Reference Figure 3-Figure 5 As shown, the cleaning mechanism 300 includes: a first mounting frame 301, a mounting seat 304, a mounting plate 305 and a cleaning brush 306; wherein, the first mounting frame 301 is fixedly provided on the base 100, a driving motor 303 is fixedly provided on the first mounting frame 301, the output shaft of the driving motor 303 is horizontally arranged and a second bidirectional screw 302 is fixedly provided on the top through a shaft coupling, the second bidirectional screw 302 is provided with two sections of threads with opposite screw directions, and the two sections of threads are respectively threaded with a mounting seat 304, a mounting plate 305 with an adjustable upper and lower spacing is fixedly provided on the side of the mounting seat 304, and a cleaning brush 306 in contact with the surface of the steel plate is fixedly provided on the opposite side of the mounting plate 305.

[0042] Before starting work, according to the thickness of the steel plate to be processed, by adjusting the rotation direction of the second bidirectional screw 302, the two mounting seats 304 are moved relative to or away from each other along the axial direction of the second bidirectional screw 302, thereby adjusting the spacing between the two mounting seats 304 to adapt to steel plates of different thicknesses. After the mounting seats 304 are adjusted into place, the upper and lower positions of the mounting plates 305 in the mounting seats 304 are adjusted according to the upper and lower surface positions of the steel plates to ensure that the cleaning brush 306 can be in close contact with the upper and lower surfaces of the steel plates. The cleaning mechanism 300 can be adjusted according to the steel plates of different thicknesses to ensure that the cleaning brush 306 is always in close contact with the surface of the steel plates, thereby improving the cleaning effect.

[0043] Reference Figure 4-Figure 5 As shown, each set of mounting seats 304 is provided with a limiting member for limiting the transported steel plates up and down, left and right, and preventing them from deflecting.

[0044] Before starting work, adjust the position of the limiter in the mounting seat 304 according to the width and thickness of the steel plate to be processed to ensure that the limiter can limit the steel plate up, down, left and right to prevent the steel plate from shifting during transmission. When the steel plate enters the cleaning mechanism 300, the limiter begins to limit the steel plate to ensure that the steel plate remains stable during transmission. While the cleaning brush 306 is cleaning the steel plate, the limiter continues to limit the steel plate to prevent the steel plate from shifting due to vibration or external force during the cleaning process.

[0045] Reference Figure 5 As shown, the limiting member includes: a limiting roller 307, a lower pressure roller 308 and an upper pressure roller 309; wherein, a limiting roller 307 is rotatably provided inside the mounting seat 304, a lower pressure roller 308 is provided on its inner bottom wall, and an upper pressure roller 309 for limiting the upper and lower positions of the steel plate is connected to the inner top wall of the mounting seat 304 at a position corresponding to the lower pressure roller 308 through a spring column 310.

[0046] Before starting work, according to the width of the steel plate to be processed, the position of the limiting roller 307 in the mounting seat 304 is adjusted to ensure that the limiting roller 307 can limit the steel plate in the left and right directions. Through the elastic force of the spring column 310, the upper pressure roller 309 is in contact with the upper surface of the steel plate and exerts a certain pressure to ensure that the steel plate will not deviate in the up and down directions during the transmission process. When the steel plate enters the cleaning mechanism 300, the limiting roller 307 limits the steel plate in the left and right directions, and at the same time, the lower pressure roller 308 and the upper pressure roller 309 limit the steel plate in the up and down directions to ensure that the steel plate remains stable during the transmission process.

[0047] Reference Figure 6-Figure 7 As shown, the mounting plate 305 is provided with an adjustment component 500 for adjusting the distance between the two mounting plates 305 in the vertical direction.

[0048] In the above scheme, according to the thickness of the steel plate to be processed, the distance between the two mounting plates 305 in the vertical direction is adjusted by adjusting the component 500, ensuring that the cleaning brush 306 is always in close contact with the surface of the steel plate, thereby improving the cleaning effect.

[0049] Reference Figure 6-Figure 7As shown, the adjustment component 500 includes: a gear 502, a connecting rod 503, a rotating rod 504 and a rack 507; wherein, a second mounting frame 501 is fixedly provided on one of the mounting plates 305, a gear 502 is rotatably provided in the second mounting frame 501, a connecting rod 503 is fixedly provided on the rotating shaft of the gear 502, one end of the connecting rod 503 is rotatably connected to the rotating rod 504, the bottom end of the rotating rod 504 is rotatably connected to a fixed block 505 fixedly provided on another mounting plate 305, a hydraulic rod 506 is fixedly provided in parallel on the mounting plate 305, and a rack 507 meshing with the gear 502 is fixedly provided at the output end of the hydraulic rod 506.

[0050] In the above scheme, before adjustment, the two mounting plates 305 are kept at a certain distance by the adjustment assembly 500, the hydraulic rod 506 is in an unextended state, the rack 507 is not fully meshed with the gear 502 or is in an initial meshing position, and according to the size of the spacing to be adjusted, the hydraulic rod 506 is started, so that its output end pushes the rack 507 to move parallel to the mounting plate 305, and as the rack 507 moves, the meshing relationship between the rack 507 and the gear 502 changes, causing the gear 502 to start rotating, and the rotation of the gear 502 drives the rotating rod 504 to rotate through the connecting rod 503. Since one end of the rotating rod 504 is rotatably connected to the fixed block 505 on the other mounting plate 305, the rotation of the rotating rod 504 will be converted into a relative movement between the two mounting plates 305, and as the gear 502 continues to rotate, the distance between the two mounting plates 305 gradually increases or decreases until the required adjustment position is reached.

[0051] Reference Figure 1-Figure 3 As shown, the left and right limit mechanism 200 includes: a limit rod 201, a first bidirectional screw 202 and a limit plate 203; wherein, the limit rod 201 is fixedly provided on the first bracket 103, and the first bidirectional screw 202 is rotatably provided on the inner wall thereof, the first bidirectional screw 202 is transmission-connected to the output shaft of the driving motor 303 through the first transmission belt 204, and the first bidirectional screw 202 is provided with two sections of threads with opposite screw directions, and the two sections of threads respectively thread through the limit plate 203, and the side wall of the limit plate 203 is fixedly provided with a first pressure sensor 205 electrically connected to the driving motor 303.

[0052] In the above scheme, the drive motor 303 is started according to the width of the steel plate to be limited. The output shaft of the drive motor 303 drives the first bidirectional screw 202 to rotate through the first transmission belt 204. As the first bidirectional screw 202 rotates, the two sections of the screw thread with opposite directions respectively drive the two limit plates 203 to move in opposite directions. When the steel plate enters the left and right limit mechanisms 200, the two sides of the steel plate contact the two limit plates 203 respectively and are limited in a predetermined position. At this time, the first pressure sensor 205 senses the pressure and controls the drive motor 303 to stop running. The design of the left and right limit mechanisms 200 allows the spacing of the limit plates 203 to be adjusted according to steel plates of different widths, thereby improving the adaptability and flexibility of the equipment.

[0053] Reference Figure 1-Figure 8 As shown, the cold rolling mechanism 400 includes: a second bracket 401, a lower rolling roller 404 and an upper rolling roller 405; wherein, the second bracket 401 is fixedly provided on the upper surface of the base 100, and the lower rolling roller 404 and the upper rolling roller 405 which can slide up and down along the second bracket 401 are rotatably provided on the inner wall of the second bracket 401.

[0054] In the above scheme, the steel plate that has undergone preliminary treatment is fed into the cold rolling mechanism 400, passes through the left and right limiting mechanisms 200 and the cleaning mechanism 300, and enters the gap between the lower roller 404 and the upper roller 405. The steel plate is clamped by the upper and lower rollers and is subjected to pressure to undergo plastic deformation, thereby achieving cold rolling treatment.

[0055] Reference Figure 8 As shown, the second bracket 401 is provided with a driving member for adjusting the height of the upper roller 405, and the driving member includes: a screw rod 402, a threaded block 403, a driven bevel gear 406 and an active bevel gear 407; wherein, a screw rod 402 is rotatably provided inside the second bracket 401, a threaded block 403 is threadedly penetrated on the screw rod 402, the upper roller 405 is rotatably provided on the side of the threaded block 403, a driven bevel gear 406 is fixedly sleeved on the top end of the screw rod 402, a driving shaft 410 is rotatably penetrated on the side of the second bracket 401, an active bevel gear 407 meshing with the driven bevel gear 406 is fixedly sleeved on the driving shaft 410, and a rotating motor 408 with an output end fixedly connected to the driving shaft 410 is also fixedly provided on the side of the second bracket 401, and each two groups of driving shafts 410 are connected by a second transmission belt 409.

[0056] Before cold rolling, according to the thickness of the steel plate and the required cold rolling pressure, the height of the upper roller 405 needs to be adjusted by the driving member to form a suitable rolling gap, and the rotary motor 408 is started to drive the driving shaft 410 to rotate. Since the driving shaft 410 is fixedly sleeved with an active bevel gear 407, the active bevel gear 407 also starts to rotate, and the active bevel gear 407 meshes with the driven bevel gear 406, so the driven bevel gear 406 also starts to rotate. The driven bevel gear 406 is fixedly sleeved on the top of the screw rod 402, so the screw rod 402 also starts to rotate. As the screw rod 402 rotates, the thread block 403 moves on the screw rod 402 along the thread direction. Since the upper roller 405 is rotatably arranged on the side of the threaded block 403, the upper roller 405 also moves accordingly, thereby adjusting the gap between the upper roller 405 and the lower roller 404. After the gap is adjusted, the rotating motor 408 continues to work, driving the lower roller 404 and the upper roller 405 to rotate, and the steel plate is cold-rolled. Through the precise adjustment of the driving part, the height of the upper roller 405 can be precisely controlled, thereby forming a suitable rolling gap to meet the cold rolling requirements of steel plates of different thicknesses.

[0057] Reference Figure 8 As shown, a second pressure sensor 411 electrically connected to the rotating motor 408 is fixedly provided on the circumferential surface of the upper roller 405 .

[0058] During the cold rolling process, the second pressure sensor 411 is fixed on the circumferential surface of the upper roller 405 to monitor the pressure applied by the upper roller 405 to the steel plate in real time. The second pressure sensor 411 transmits the monitored pressure data to the control system, and the control system processes and analyzes the received data to determine whether the pressure during the cold rolling process is appropriate. If the control system finds that the pressure during the cold rolling process is too large or too small, it can adjust the height of the upper roller 405 by rotating the motor 408, thereby changing the rolling gap and the cold rolling pressure.

[0059] In summary, the present invention provides a container processing high-speed cold rolling mill. When in use, the steel plate is first placed on the unwinding roller 101, and the unwinding roller 101 is fixedly installed on the base 100. After the steel plate is unwound from the unwinding roller 101, it is initially supported and guided by the support roller 104 in the first bracket 103. After the steel plate enters the first bracket 103, the driving motor 303 drives the first bidirectional screw 202 to rotate through the first transmission belt 204, so that the limit plates 203 on the two sections of the screw threads with opposite directions move toward the middle, and the left and right sides of the steel plate are limited to prevent the steel plate from shifting during transportation. The first pressure sensor 205 on the limit plate 203 can monitor in real time The pressure of the steel plate ensures that the limiting force is moderate. After the limiting, the steel plate enters the cleaning mechanism 300 for surface cleaning. The driving motor 303 drives the second bidirectional screw 302 to rotate, so that the mounting seat 304 moves in the horizontal direction, thereby adjusting the position of the cleaning brush 306 to adapt to steel plates of different widths. The limiting member in the mounting seat 304 limits the steel plate up and down, left and right, to prevent the steel plate from shifting during the cleaning process. The cleaning brush 306 contacts the surface of the steel plate to remove dirt and impurities on the surface of the steel plate. The cleaned steel plate enters the cold rolling mechanism 400 for cold rolling treatment. The upper roller 405 can slide up and down along the second bracket 401 to adapt to steel plates of different thicknesses. The rotating motor 408 drives the driving shaft 410 to rotate through the second transmission belt 409, thereby driving the active bevel gear 407 to rotate. The active bevel gear 407 meshes with the driven bevel gear 406 to rotate the screw rod 402. The threaded block 403 on the screw rod 402 drives the upper roller 405 to move up and down, and adjusts the gap between the upper roller 405 and the lower roller 404. When the steel plate passes through the gap between the lower roller 404 and the upper roller 405, it is cold rolled to achieve the required thickness and hardness. The cold rolled steel plate enters the stress relief part 102 for stress relief treatment.
