Description

Technical Field

[0001] This utility model belongs to the technical field of uncoiler centering devices, and specifically relates to an automatic centering device for an uncoiler. Background Technology

[0002] During the operation of galvanized steel strip, the strip's position may change, requiring a centering device to detect and correct any positional deviations. Especially after the strip has traveled a section on the uncoiler, the center position may shift. Existing correction devices often have inaccurate correction values, making it difficult to detect and accurately correct these deviations in a timely manner. This frequently leads to issues such as edge scraping, affecting product quality. Therefore, a centering device for the uncoiler that can automatically adjust and correct these deviations is needed. Summary of the Invention

[0003] This utility model provides an automatic centering device for an uncoiler to solve the technical problems existing in the prior art. It uses a displacement sensor and a measuring light curtain to provide real-time feedback on the position changes of the strip, and at the same time controls the equipment to adjust the position to achieve the purpose of automatic centering.

[0004] This utility model includes the following technical solution:

[0005] An automatic centering device for an uncoiler includes an adjustable drum, a detection frame positioned in front of the drum, a hydraulic cylinder, and a control terminal. An external support arm is connected to one side of the drum, and a reducer is connected to the other side. The reducer is connected to a motor. During the uncoiling process, the strip steel passes through the middle of the detection frame along a conveying path driven by the drum. A measuring light curtain is installed inside the detection frame to detect the passing strip steel and transmits the data to the control terminal. Both the reducer and the motor are installed inside the frame. A sliding plate is fixed to the bottom of the frame and positioned on a matching track. A position sensor is fixed to the side of the hydraulic cylinder. The front end of the piston rod of the hydraulic cylinder is fixed to the frame via a connecting block. The position sensor detects the distance between the rear end face of the frame and the position sensor probe and transmits the data to the control terminal. The control terminal adjusts the position of the strip steel by controlling the extension amount of the piston rod of the hydraulic cylinder.

[0006] Furthermore, the strip moves horizontally along the x-axis and passes through the detection range of the measuring light curtain, the width of the strip being smaller than the detection range of the measuring light curtain. A set of measuring light curtains is installed on the inner sides of the two horizontal beams of the detection frame.

[0007] Furthermore, the detection accuracy of the measuring light curtain is 1 mm.

[0008] Furthermore, the drum position is adjusted by moving it horizontally along the y-axis, thereby adjusting the positional relationship between the strip steel and the detection frame.

[0009] Furthermore, a sliding plate is installed at each end of the bottom surface of the frame, and three horizontal tracks parallel to the y-axis are provided under the sliding plate to ensure that the reducer and motor are sufficiently stable during position adjustment.

[0010] Furthermore, a fixing frame is connected to the rear end of the track, and a cylinder seat is installed on the fixing frame to fix the position of the cylinder. The operator can decide whether to install support feet that connect to the ground based on the size and specifications of the cylinder.

[0011] Furthermore, the rear end of the track is provided with a shock-absorbing block, and when the slide plate moves to the position of contacting the shock-absorbing block, the extension amount of the piston rod is 0.

[0012] Furthermore, the connecting block is located in the middle of the rear end face of the frame.

[0013] Furthermore, the control terminal is located next to the outer support arm, and the control terminal is equipped with a display panel and a loudspeaker. When abnormal data occurs, the control terminal will issue an alarm through the loudspeaker.

[0014] The advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model achieves automatic centering adjustment of strip steel through the cooperation of position sensor, detection frame, hydraulic cylinder and control terminal, reducing the risk of strip steel scraping edge, with high degree of automation and simple structural layout.

[0016] 2. This utility model is convenient, flexible, and easy to operate. The strip steel can be manually or automatically adjusted through the control terminal, which reduces the workload of operators and lowers the operational risks. Attached Figure Description

[0021] Example: See Appendix Figure 1 An automatic centering device for an uncoiler includes a position-adjustable drum 2, a detection frame 3 located in front of the drum 2, a hydraulic cylinder 11, and a control terminal 14; one side of the drum 2 is connected to an outer support arm 4 and the other side is connected to a reducer 5, the reducer 5 is connected to a motor 6, and the drum 2 moves horizontally along the y-axis when its position is adjusted, thereby adjusting the positional relationship between the strip 1 and the detection frame 3.

[0022] During the uncoiling process, the strip steel 1, driven by the drum 2, passes through the middle of the detection frame 3 along the conveying path. A measuring light curtain 301 is installed inside the detection frame 3 to detect the passing strip steel 1 and send the data to the control terminal 14. The strip steel 1 moves horizontally along the x-axis and passes through the detection range of the measuring light curtain 301, and the width of the strip steel 1 is smaller than the detection range of the measuring light curtain 301. The detection accuracy of the measuring light curtain 301 is 1 mm.

[0023] The reducer 5 and the motor 6 are both installed inside the frame 7. The bottom of the frame 7 is fixed with a slide plate 8, which is set on a matching track 9. A slide plate 8 is installed at each end of the bottom surface of the frame 7. Three tracks 9 parallel to the y-axis in the horizontal direction are provided below the slide plate 8 to ensure that the reducer 5 and the motor 6 are sufficiently stable during position adjustment.

[0024] A position sensor 12 is fixedly mounted on the side of the hydraulic cylinder 11. The front end of the piston rod 112 of the hydraulic cylinder 11 is fixedly connected to the frame 7 via a connecting block 10, which is located in the middle of the rear end face of the frame 7. The position sensor 12 detects the distance between the rear end face of the frame 7 and the probe of the position sensor 12 and sends the data to the control terminal 14. The control terminal 14 adjusts the position of the strip steel 1 by controlling the extension of the piston rod 112 of the hydraulic cylinder 11. The control terminal 14 is located next to the outer support arm 4 and is equipped with a display panel and a loudspeaker. When abnormal data occurs, the control terminal 14 will issue an alarm through the loudspeaker.

[0025] The rear end of the track 9 is connected to a fixing frame 13, which is an isosceles triangle structure. A cylinder seat 111 is installed on the fixing frame 13 to fix the position of the cylinder 11. The cylinder seat 111 is located at the apex of the isosceles triangle. The operator can decide whether to install support feet connected to the ground on the fixing frame 13 according to the size specifications of the cylinder 11. The rear end of the track 9 is provided with a shock-absorbing block. When the slide plate 8 moves to the position of contacting the shock-absorbing block, the extension of the piston rod 112 is 0.

[0026] Working process: After the uncoiler unwinds the strip 1, the strip 1 moves continuously to the right along the x-axis through the detection frame 3. When the running position of the strip 1 deviates, and the deviation reaches a certain value (this value is input by the operator on the control terminal 14), the detection frame 3 transmits the data to the control terminal 14. The display panel shows the deviation value, and then the control terminal 14 controls the hydraulic cylinder 11 to extend or retract its piston rod 112. The displacement sensor 12 continuously transmits the movement of the hydraulic cylinder 11 to the control terminal 14. The motor 6 and the reducer 5 move forward or backward on the track 9 through the action of the hydraulic cylinder 11. Finally, the detection frame 3 detects whether the position of the strip 1 is correct. If the position is correct, the adjustment action stops.

[0027] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims.
