Description

Technical Field

[0001] This utility model relates to the field of film production equipment technology, and in particular to a correction mechanism and correction system for a steel strip casting machine. Background Technology

[0002] A steel strip casting machine is a device used to prepare thin film materials, widely used in new energy (such as lithium battery separators), electronics (ceramic substrates), photovoltaics, and pharmaceuticals. The working principle of a steel strip casting machine is to uniformly coat the slurry onto the surface of a moving steel strip, and then form a film of uniform thickness through processes such as drying and curing.

[0003] Due to traction force and manufacturing errors, the steel strip in a steel strip casting machine is prone to shifting left or right or even deviating from the track during transmission. Therefore, a correction mechanism is usually installed on the steel strip casting machine to correct the deviation of the steel strip.

[0004] The existing web-alignment mechanism has low detection accuracy, resulting in low web-alignment accuracy and the problem of incomplete web-alignment, which affects the production of thin films. Utility Model Content

[0005] In response to the shortcomings of the existing correction mechanisms in steel strip casting machines, the applicant provides a reasonably structured correction mechanism and system for steel strip casting machines, which improves detection accuracy, ensures proper correction, and guarantees film production.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A correction mechanism for a steel strip casting machine includes a lifting mechanism and a detection mechanism on the frame. The detection mechanism is located on both sides of the steel strip and is configured to detect the offset displacement of the steel strip. The lifting mechanism is connected to the bearing seat of the roller and is configured to adjust the position of the bearing seat according to the offset of the steel strip to correct the steel strip.

[0008] As a further improvement to the above technical solution:

[0009] The detection mechanism is equipped with inductive sensing components and / or contact sensing components, which detect the deviation of the steel strip.

[0010] The inductive sensing assembly includes a first position sensor, a second position sensor, and a third position sensor mounted on a bracket; the first position sensor is a centering position sensor configured to detect the position of the steel strip side edge at the centering position; the second position sensor is an intermediate sensor configured to detect the position of the steel strip side edge at the offset position; and the third position sensor is an extreme position sensor configured to detect the position of the steel strip side edge at the extreme position.

[0011] The first position sensor, the second position sensor, and the third position sensor each include two upper and two lower probes disposed on the upper and lower sides of the steel strip. The two probes detect the side edge position of the steel strip by sensing, and the probes are fiber optic sensors.

[0012] The maximum offset travel that the first, second, and third position sensors can detect is ±25mm.

[0013] The first, second, and third position sensors take an average of 45 to 55 samples per revolution of the steel belt.

[0014] The contact sensing component includes a guide wheel, a reset component, a slide rail, and a second displacement sensor mounted on a bracket. The guide wheel contacts the side edge of the steel belt and is connected to the slide rail, which is movably mounted on the bracket. The second displacement sensor is connected to the bracket.

[0015] The support frame of the testing mechanism is equipped with a horizontal adjustment structure and a vertical adjustment structure.

[0016] The lifting mechanism includes a lift, a motor, a connecting shaft, and a weighing sensor. The lift is connected to the motor, one end of the connecting shaft is connected to the lead screw of the lift, and the other end is connected to the bearing seat of the roller. The weighing sensor is connected to the connecting shaft. The motor is a servo motor. A first displacement sensor is installed on the bearing seat of the roller.

[0017] A belt deviation correction system includes a belt deviation correction mechanism and a PLC control system. A lifting mechanism, a detection mechanism, and a first displacement sensor are connected to the PLC control system. The detection mechanism sends the steel strip offset signal detected by the sensor to the PLC control system. The PLC control system drives the lifting mechanism to move according to the steel strip offset, thereby moving the bearing seat of the roller on the guide rail to correct the belt deviation.

[0018] The beneficial effects of this utility model are as follows:

[0019] The detection mechanism of this invention uses inductive sensing components and / or contact sensing components to detect the deviation of the steel strip in real time. The lifting mechanism adjusts the position of the roller according to the deviation signal to correct the deviation of the steel strip in a timely manner, which improves the detection accuracy and response speed, ensures that the deviation correction is in place and timely, and guarantees the production of the film.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, this utility model provides a correction mechanism suitable for a steel strip casting machine. A roller 2 is mounted on the frame 1 of the steel strip casting machine, and a steel strip 3 is wound around the roller 2 in a tensioned state. Bearing seats 21 are connected to both ends of the roller 2, and the bearing seats 21 are movably mounted on the guide rail 11 of the frame 1 via sliders. Lifting mechanisms 4 are respectively provided on the frame 1 at both ends corresponding to the roller 2, and the lifting mechanisms 4 are connected to the bearing seats 21 at both ends of the roller 2. The lifting mechanisms 4 can drive the bearing seats 21 to move along the guide rail 11. Detection mechanisms 5 are respectively provided on both sides of the frame 1 corresponding to the steel strip 3, and the detection mechanisms 5 can detect the offset displacement of the steel strip 3.

[0027] A first displacement sensor 22 is provided on the bearing seat 21 of the roller 2. The first displacement sensor 22 can detect the displacement difference of the bearing seats 21 at both ends of the roller 2.

[0028] like Figure 1 As shown, the lifting mechanism 4 includes a lifting platform 41, a motor 42, a connecting shaft 43, and a load cell 44. The lifting platform 41 is connected to the motor 42, and its movement is controlled by the motor 42. One end of the connecting shaft 43 is connected to the lead screw of the lifting platform 41, and the other end is connected to the bearing seat 21 of the roller 2. The load cell 44 is connected to the connecting shaft 43. The motor 42 is a servo motor. The output pressure of the lifting platform 41 is controlled by the rotation speed of the motor 42, thereby controlling the movement of the lead screw of the lifting platform 41. The connecting shaft 43 drives the bearing seat 21 to move on the guide rail 11, adjusting the roller 2. The load cell 44 is used to monitor the tension of the steel belt 3, ensuring that the steel belt 3 maintains appropriate tension.

[0029] like Figures 2 to 4As shown, the detection mechanism 5 is equipped with an inductive sensing component, which includes a first position sensor 51, a second position sensor 52, and a third position sensor 53 mounted on a bracket 54, used to detect the side edge position of the steel strip 3. The first position sensor 51 is a centering position sensor, configured to detect the side edge position of the steel strip 3 at the centering position (when the steel strip 3 is not offset); the second position sensor 52 is an intermediate sensor, configured to detect the side edge position of the steel strip 3 at the offset position (before reaching the limit position); and the third position sensor 53 is a limit position sensor, configured to detect the side edge position of the steel strip 3 when it has offset to the limit position. The maximum offset travel that the first position sensor 51, second position sensor 52, and third position sensor 53 can detect is ±25mm. The first position sensor 51, second position sensor 52, and third position sensor 53 each include two probes positioned opposite each other, one above and one below, located on the upper and lower sides of the steel strip 3, respectively. The probes are fiber optic sensors used to detect the side edge position of the steel strip 3. The first position sensor 51, the second position sensor 52, and the third position sensor 53 sample an average of 45 to 55 times within one revolution of the steel belt 3. This is achieved through 50 stacked first-in-first-out filtering to avoid false alarms caused by edge offset during the operation of the steel belt 3 due to accidental interference, thus ensuring the accuracy of the detection.

[0030] The support 54 of the detection mechanism 5 is equipped with a horizontal adjustment structure and a vertical adjustment structure (not shown in the figure). The positions of the first position sensor 51, the second position sensor 52, and the third position sensor 53 can be adjusted through the adjustment structure to adapt to the actual operation of the steel belt 3.

[0031] like Figure 4 As shown, the detection mechanism 5 can also be equipped with a contact sensing component. This contact sensing component includes a guide wheel 55, a reset component 56, a slide rail 57, and a second displacement sensor 58, all mounted on the bracket 54. The guide wheel 55 is connected to the slide rail 57, which is movably mounted on the bracket 54. The second displacement sensor 58 is connected to the bracket 54 and can detect the offset. The guide wheel 55 contacts the side edge of the steel belt 3. When the steel belt 3 shifts, the guide wheel 55 drives the slide rail 57 to move, and the reset component 56 can reset the slide rail 57 and the guide wheel 55.

[0032] The inductive sensing component and the contact sensing component of the detection unit 5 can be used either one or both.

[0033] This utility model also provides a correction system, including the above-mentioned correction mechanism and a PLC control system (not shown in the figure). The lifting mechanism 4, the detection mechanism 5 and the first displacement sensor 22 are connected to the PLC control system. The detection mechanism 5 sends the offset signal of the steel strip 3 detected by the sensor to the PLC control system. The PLC control system drives the lifting mechanism 4 to move according to the offset of the steel strip 3, which drives the bearing seat 21 of the roller 2 to move on the guide rail 11 to correct the steel strip 3 and control the offset of the steel strip 3 within the allowable threshold range.

[0034] The detection mechanism 5 of this utility model detects the deviation of the steel strip 3 in real time through inductive sensing components and / or contact sensing components. The lifting mechanism 4 adjusts the position of the roller 2 according to the deviation signal to correct the deviation of the steel strip 3 in a timely manner, which improves the detection accuracy and response speed, ensures that the deviation correction is in place and timely, and guarantees the production of the film.

[0035] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
