Description

Technical Field

[0001] The invention relates to the technical field of steel strip production and processing equipment, and in particular to a steel strip deviation correction structure of a cold rolling production line. Background Art

[0002] Cold rolled steel strip is a steel product processed by cold rolling process. It has high strength, high precision and good surface quality and is widely used in automobile, home appliance, construction and other industries. In the cold rolling production line, the steel strip passes through a series of equipment and process steps, such as uncoiling, straightening, rolling, shearing, etc., and finally forms a finished product that meets the requirements. The conveying of steel strip is a key link in the cold rolling production line. It is necessary to ensure that the steel strip runs smoothly and continuously so that the subsequent processes can proceed normally.

[0003] At present, there are many kinds of conveying equipment used in cold rolling production lines, including conveyors, lifting devices, roller tables, etc. The design of these equipment fully considers factors such as the weight, size and conveying efficiency of the steel strip, ensuring the smooth conveying of the steel strip on the production line. However, in the actual production process, the steel strip will deviate due to various reasons, such as poor raw material shape, uneven equipment installation, and tilted tension rollers. The deviation of the steel strip will not only affect the normal operation of the production line, but may also cause equipment damage and product quality degradation. Therefore, timely deviation correction during the conveying process is an important measure to ensure production efficiency and product quality.

[0004] However, the existing correction process has some obvious disadvantages. Whether it is manual correction or automatic correction system, most of the correction operations are performed when the steel belt is straight. This correction method changes the position of the steel belt by adjusting the tension or moving the correction roller, but in this process, the straight steel belt will be subjected to additional bending stress. When the steel belt is subjected to excessive bending stress, it may bend in the transverse plane, or even cause the steel belt to break or crack. This will not only reduce the quality and output of the product, but also increase production costs and safety hazards. Summary of the invention

[0005] In order to overcome the disadvantage that the steel strip is damaged by bending stress, the present invention provides a steel strip deviation correction structure for a cold rolling production line.

[0006] The strip correction structure of the cold rolling production line includes a base, a conveyor frame and rollers. Conveyor frames are installed at both ends of the base.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0027] Example: Strip steel deviation correction structure of cold rolling production line, such as Figure 1-Figure 8As shown, it includes a base 1, a conveying frame 2 and a roller 3. The conveying frames 2 are installed at both ends of the base 1. The rollers 3 are rotatably connected inside the conveying frames 2. After the steel strip leaves the steel coil, it passes through the front and rear conveying frames 2 in sequence and passes through the middle of the rollers 3 on the conveying frames 2. The rollers 3 are in contact with the steel strip to ensure the stability of the movement of the steel strip. It also includes a folding mechanism 4, a correcting mechanism 5 and a cleaning mechanism 6. The folding mechanism 4 is arranged in the middle of the base 1. The correcting mechanism 5 for laterally deflecting the steel strip is arranged on the folding mechanism 4. The folding mechanism 4 is used to adjust the spacing of the correcting mechanism 5. The front conveying frame 2 is provided with a cleaning mechanism 6 for cleaning the steel strip.

[0028] like Figure 3 and Figure 4 As shown, the folding mechanism 4 includes a placement plate 41, a sliding seat 42, a first motor 43, a rack 44, a transmission wheel 45 and a connecting rod 46. The two placement plates 41 are respectively connected to the left and right ends of the top of the base 1 and are located between the two conveying frames 2. Four sliding seats 42 are slidably connected in each placement plate 41. The middle of each sliding seat 42 is rotatably connected with a connecting rod 46, and the adjacent connecting rods 46 on the same side are rotatably connected to ensure that the spacing between the four sliding seats 42 can be flexibly adjusted. The first motor is installed on the front end sliding seat 42. 43, a rack 44 is provided on the top surface of the front end of the placement plate 41, and the output shaft of the first motor 43 is connected to a transmission wheel 45, which meshes with the rack 44. When the first motor 43 is started, the first motor 43 drives the transmission wheel 45 to rotate, and the sliding seat 42 at the front end is moved in the placement plate 41 through the fixed rack 44, and the connecting rod 46 rotates between the sliding seats 42, thereby changing the spacing between the sliding seats 42, and the correction mechanism 5 is located on the sliding seat 42 of the folding mechanism 4, so the spacing of the correction mechanism 5 also changes synchronously.

[0029] like Figure 5As shown, the deviation correction mechanism 5 includes a mounting frame 51, a screw rod 52, a sliding frame 53, a pressing roller 54, a second motor 55 and a third motor 56. The two ends of the mounting frame 51 are respectively fixedly connected to the corresponding sliding seats 42 in the left and right placement plates 41, and the mounting frame 51 and the placement plates 41 are perpendicular to each other. The mounting frame 51 is perpendicular to the movement direction of the steel belt. The mounting frame 51 is slidably connected with the sliding frame 53, and the mounting frame 51 is rotatably connected with the screw rod 52. The end of the screw rod 52 passes through the mounting frame 51, and the screw rod 52 is threadedly connected to the sliding frame 53. The rotating screw rod 52 can move the sliding frame 53 left and right. A second motor 55 is installed at the end of the mounting frame 51. The output shaft of the second motor 55 is fixedly connected to the end of the screw rod 52. Two mutually contacting clamping rollers 54 are connected, and the steel belt passes between the two clamping rollers 54. A third motor 56 is installed on each mounting frame 51, and the third motor 56 is fixedly connected to one of the clamping rollers 54 on the same mounting frame 51. When the second motor 55 is turned on, the second motor 55 moves the sliding frame 53 left and right through the screw rod 52, thereby driving the clamping roller 54 on the sliding frame 53 to move left and right. The clamping rollers 54 in contact with each other have enough pressure on the steel belt, thereby driving the steel belt to deviate left and right, and when the third motors 56 on different sliding frames 53 are turned on separately, the length of the steel belt between the two mounting frames 51 can be adjusted. The third motor 56 does not have a self-locking function, that is, when the third motor 56 is turned off, the clamping roller 54 can rotate arbitrarily.

[0030] like Figure 6-Figure 8 As shown, the cleaning mechanism 6 includes a mounting plate 61, a cleaning roller 62, a fourth motor 63 and a gear set 64. The left and right ends of the rear side of the front conveying frame 2 are connected with mounting plates 61. Two cleaning rollers 62 are rotatably connected between the two mounting plates 61. The ends of the two cleaning rollers 62 are commonly connected with a gear set 64. The gear set 64 is composed of two gears meshing with each other, so that the rotation directions of the two cleaning rollers 62 are opposite. A fourth motor 63 is installed on the mounting plate 61. The fourth motor 63 is fixedly connected to the end of one of the cleaning rollers 62. After the fourth motor 63 is turned on, the rotation direction of the cleaning roller 62 and the position where the cleaning roller 62 contacts the steel belt are controlled. The rotation direction of the cleaning roller 62 is opposite to the moving direction of the steel belt and is transmitted through the gear set 64, so that the rotation direction of the other cleaning roller 62 is also opposite to the moving direction of the steel belt. The steel belt and the cleaning roller 62 slide against each other at a sufficient distance to ensure the cleaning effect of the steel belt.

[0031] like Figure 2As shown, it also includes an offset sensor 7 and a control panel 71. The front and rear conveyor frames 2 are both equipped with offset sensors 7. The offset sensors 7 are respectively provided with two detection heads at the bottom and the front side to ensure accurate measurement. The front and rear conveyor frames 2 are both equipped with control panels 71. The control panel 71 is wiredly connected to the offset sensor 7 and all motors. The control panel 71 processes the measurement results of the offset sensor 7, and controls the start and stop of the corresponding motors after calculation to complete the deviation correction work.

[0032] like Figure 6 As shown, it also includes cleaning strips 65. Three arc-shaped cleaning strips 65 are connected to each cleaning roller 62. The protruding cleaning strips 65 can further ensure the cleaning effect of the steel strip.

[0033] like Figure 5 As shown, the pressure roller 54 is provided with an annular rubber roller groove 541, which is completely perpendicular to the axial direction of the pressure roller 54. The pressure roller 54 moves left and right to adjust the position of the steel belt. The design of the rubber roller groove 541 enables the pressure roller 54 to adaptively form a certain elastic contact with the steel belt when in contact with the steel belt, which helps to reduce the force on the steel belt when moving the steel belt laterally and prevent cracks or breaks in the steel belt.

[0034] like Figure 8 As shown, a protective plate 66 is also included. The rear side of the front conveying frame 2 is connected with the protective plate 66 . The protective plate 66 is connected to the mounting plate 61 , and the mounting plate 61 and the protective plate 66 cover the gear set 64 .

[0035] The steel belt passes through the middle of the rollers 3 of the two conveyor frames 2 to maintain the basic transportation function. When the steel belt passes through the two offset sensors 7, the control panel 71 collects detection data, determines the values ​​detected by the front and rear sensors, calculates the offset, and pre-sets the adjustment amount and the correction amount. When the calculated offset is greater than the fine-tuning threshold but less than the correction threshold, only the second motor 55 is started for fine-tuning; when the offset is greater than or equal to the correction threshold, the folding mechanism 4 and the correction mechanism 5 are started for correction. The steel belt passes through the middle of the cleaning roller 62 at the front end, and the cleaning strip 65 on the cleaning roller 62 cleans the surface of the steel belt. The fourth motor 63 drives the two cleaning rollers 62 to rotate through the gear set 64. The protective plate 66 can prevent the steel belt from contacting the gear set 64, protect the steel belt, and complete the cleaning of the steel belt, ensuring the friction between it and the clamping roller 54, thereby ensuring the correction effect of the correction mechanism 5 on the steel belt.

[0036] When fine-tuning, the control panel 71 only starts the different second motors 55, and the second motors 55 drive the screw rods 52 to rotate, thereby driving the sliding frame 53 to move left and right, and the sliding frame 53 drives the pressing roller 54 to move laterally, and the friction between the pressing roller 54 and the steel belt is used to make the steel belt move laterally, thereby completing the fine-tuning;

[0037] When deviation correction is required, the third motor 56 sets the numbers A, B, C and D in sequence from front to back, the control panel 71 records the corresponding numbers, the steel belt stops conveying, and C, B and A are turned on in sequence. When only C is turned on, the part of the steel belt between C and D will be conveyed backwards. Since D is not turned on, this part of the steel belt will bend on the sliding frame 53 between C and D, and so on, so that a certain amount of steel belt margin is retained between every two adjacent sliding frames 53. Then the first motor 43 is started. The first motor 43 makes all the sliding seats 42 approach each other through the cooperation of the transmission wheel 45 and the rack 44, and the transmission action of the connecting rod 46, thereby driving the sliding frame 53 to approach accordingly. Then the second motor 55 and the third motor 56 are started. By pressing While the tightening roller 54 moves the steel belt laterally, it conveys the steel belt backwards and evenly distributes the correction amount between different sliding frames 53, thereby reducing the distance of a single offset of the steel belt and reducing the lateral force of the steel belt. At the same time, the design of the rubber roller groove 541 enables the pinching roller 54 to adaptively form a certain elastic contact with the steel belt when in contact with the steel belt, thereby reducing the degree of force on the steel belt when the force is too large, further preventing cracks and breaks in the steel belt. During the correction process, the steel belt gradually flattens, and the offset sensor 7 maintains the detection state. After the correction is completed, all the third motors 56 are turned off, and the first motor 43 is started to reset all the sliding seats 42. The pinching roller 54 rotates freely following the conveying of the steel belt, and the second motor 55 is continuously controlled by the control panel 71 to perform fine-tuning.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
