Technical Field

[0001] This utility model relates to the field of rolling equipment technology, and in particular to an inline rolling equipment for non-ferrous metal processing. Background Technology

[0002] In the non-ferrous metals processing industry, rolling is a crucial step in processing non-ferrous metal ingots into products such as plates, strips, or foils using rolling equipment. As market demands for the quality, precision, and production efficiency of non-ferrous metal processed products continue to rise, the importance of inline rolling mills in production is becoming increasingly prominent. Inline rolling mills control the elongation precision and surface quality of metal materials through continuous pressure applied by multiple sets of rollers, while simultaneously achieving continuous production from "bill input - multi-pass rolling - finished product winding." They are widely used in the production of high-precision non-ferrous metal products such as electronic foil, packaging foil, and power battery electrode substrates.

[0003] However, in the existing inline rolling equipment for non-ferrous metal processing, the thickness deviation of the non-ferrous metal strip or wire itself can easily lead to uneven thickness along the length direction after rolling, which affects the quality of rolling. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an inline rolling device for non-ferrous metal processing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a continuous rolling apparatus for non-ferrous metal processing, including a rolling support bracket. One end of the rolling support bracket is fixedly mounted with a feed roller for placing the non-ferrous metal to be processed. A continuous rolling roller for rolling the non-ferrous metal material is arranged on one side of the feed roller. A detection bracket for support is arranged on the side of the continuous rolling roller near the feed roller. An adjustable detection slide is fixedly mounted inside the detection bracket. A laser rangefinder sensor for detecting the thickness of the non-ferrous metal is fixedly mounted inside the detection slide. The laser rangefinder sensor is signal-connected to a PLC control unit for automated control. The PLC control unit is signal-connected to a laser displacement sensor for detecting the position of the detection slide and an auxiliary rolling base for sliding adjustment. An auxiliary pressure roller for assisting in rolling the thickness of the non-ferrous metal is fixedly mounted at one end of the auxiliary rolling base.

[0006] Preferably, one end of the calendering support is provided with a connecting groove for supporting the feed roll and the continuous calendering roll, and a guide roller located between the feed roll and the continuous calendering roll is fixedly installed inside the calendering support.

[0007] The above technical solution is adopted as follows: The calendering support (steel structure welded and coated with anti-rust paint) has symmetrical connecting grooves at one end to support the shafts of the pay-off roll and the continuous calendering roll. The internal welded guide roller (stainless steel material) is located between the pay-off roll and the continuous calendering roll, with its axis parallel to the two rolls. The steel structure support is rigid and can withstand the calendering reaction force of the continuous calendering roll without deformation. The anti-rust paint coating is resistant to corrosion in the workshop environment. The high-precision dimensions of the connecting groove ensure the coaxiality of the pay-off roll and the continuous calendering roll, avoiding deviation during non-ferrous metal conveying. The smooth surface of the guide roller reduces friction of non-ferrous metals, prevents scratches on the material surface, and guides the material to be conveyed along a preset path (aligned with the feed inlet of the continuous calendering roll), adapting to non-ferrous metals of different widths.

An movable groove is opened inside to provide sliding guidance for the detection slide. The stainless steel detection bracket is resistant to corrosion by non-ferrous metal processing coolant. The bolt fixing ensures a firm connection with the rolling support. A smooth coating is set inside the movable groove to reduce the sliding resistance of the detection slide and avoid metal wear. The length of the movable groove is adapted to the width of the non-ferrous metal. The groove is perpendicular to the guide roller to ensure that the movement direction of the detection slide is consistent with the width direction of the material, so as to realize the full width thickness detection.

[0010] Preferably, in any of the above embodiments, the detection slide includes a drive motor connected to a PLC control unit, a drive screw for transmission, and a sliding seat for support. The drive motor is fixedly installed inside the detection bracket, and the output end of the drive motor is fixedly installed with a drive screw that rotates inside the detection bracket. The surface of the drive screw is threadedly connected to a sliding seat that moves inside the detection bracket. The two ends of the top of the sliding seat are fixedly installed with sealing films for sealing and protection.

[0011] The above technical solution is adopted as follows: the drive motor (servo motor, connected to the PLC control unit signal) of the detection slide is fixed to one end of the detection bracket, and the output end is connected to the drive screw through a coupling. The drive screw is threaded to the slide. The top two ends of the slide are bonded with sealing films (nitrile rubber material), which fit the top of the movable groove of the detection bracket. The servo motor has high driving precision and can control the slide to move accurately along the movable groove, adapting to different detection frequency requirements. The high-precision thread of the drive screw ensures that the slide moves smoothly and avoids damage to the screw thread. The slide is made of lightweight material to reduce the load on the drive motor. The sealing films can prevent metal debris and coolant from entering the movable groove, protecting the drive screw and the slide and reducing failures.

[0012] Preferably, in any of the above embodiments, the laser rangefinder is fixedly installed at the bottom of the sliding base, the laser displacement sensor is fixedly installed at one end of the sliding base and located inside the detection bracket, and the laser displacement sensor is located below the sealing film.

[0013] The above technical solution is adopted as follows: The laser rangefinder (laser triangulation method, signal connected to the PLC control unit) is fixed at the bottom of the sliding base, with the detection end vertically downward and aligned with the non-ferrous metal strip. The laser displacement sensor is fixed at one end of the sliding base, with the detection end horizontally facing the scale plate of the detection bracket and located below the sealed film. The high precision of the laser rangefinder can accurately detect the thickness of the non-ferrous metal, and the high sampling frequency captures the thickness fluctuation of the material along the length direction, providing accurate data for auxiliary rolling. The high protection performance is suitable for workshop dust and coolant environments. The laser displacement sensor monitors the position of the sliding base in real time to ensure that the laser rangefinder detects according to the preset path and avoids missed detection. The sensor is located below the sealed film to prevent the film from blocking the detection light path and ensure signal stability.

[0014] Preferably, in any of the above embodiments, the auxiliary calendering base includes an auxiliary bracket for connection and fixation, a drive cylinder for signal connection to a PLC control unit, and a calendering auxiliary base for lifting and adjusting. The auxiliary bracket is fixedly installed on the top of the sliding base, a drive cylinder is fixedly installed on one end of the auxiliary bracket, and a calendering auxiliary base that moves up and down inside the auxiliary bracket is fixedly installed on the output end of the drive cylinder. A laser verification sensor for verification and detection is fixedly installed on one end of the calendering auxiliary base.

[0015] The above technical solution is adopted as follows: the auxiliary support of the auxiliary calender is bolted to the top of the sliding seat, the drive cylinder (double-acting cylinder, connected to PLC signal) is fixed to the top of the auxiliary support, and the output end is connected to the calender auxiliary seat (aluminum alloy material) with the output end facing down. A laser calibration sensor (laser reflection type) is fixed to one end of the calender auxiliary seat, and the detection end is aligned with the auxiliary pressure roller with the detection end facing down. The stainless steel material of the auxiliary support is corrosion resistant, and the rigid connection with the sliding seat ensures that the auxiliary pressure roller and the sliding seat move synchronously.

The drive pulley assembly is fixedly installed inside the calendering auxiliary seat, and an extrusion roller that rotates inside the calendering auxiliary seat is fixedly installed at the output end of the drive pulley assembly. The extrusion roller is located above the guide roller.

[0017] The above technical solution is adopted as follows: the drive pulley group (including servo motor and synchronous pulley) of the auxiliary pressure roller is fixed inside the calendering auxiliary seat, and the extrusion roller is fixed at the output end of the drive pulley group and can rotate inside the calendering auxiliary seat. It is located directly above the guide roller (the axial spacing can be adjusted by the drive cylinder). The extrusion roller is made of wear-resistant material, and its high hardness ensures no deformation during calendering. The smooth surface avoids scratching the non-ferrous metal. The drive pulley group drives the extrusion roller to rotate synchronously (the linear speed is consistent with the speed of the non-ferrous metal strip) to avoid material slippage. The extrusion roller is located above the guide roller, forming a counter-pressure structure, which can apply pressure to the local thick area of ​​the material and correct the thickness deviation to within the threshold. It works in conjunction with the continuous calendering roller to improve the overall calendering accuracy.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. A laser rangefinder sensor for detecting the thickness of non-ferrous metals is installed at the front end of the continuous rolling roll of the non-ferrous metal processing rolling device. The difference in the laser rangefinder value can effectively determine the thickness difference of the non-ferrous metals. Based on the thickness difference, the auxiliary rolling seat is controlled to drive the auxiliary pressure roll to cooperate with the continuous rolling roll to roll the non-ferrous metals. This increases the auxiliary rolling effect on the thicker parts of the non-ferrous metals, reduces the thickness difference of the non-ferrous metals, and thus reduces the thickness difference along the length direction after rolling, thereby improving the quality of rolling.

[0019] 2. A detection bracket and a detection slide are set up to support and adjust the laser rangefinder sensor, which facilitates the adjustment of the detection position of the laser rangefinder sensor according to the width of the non-ferrous metal, and the detection position is precisely controlled by the data feedback of the laser displacement sensor.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figure 1-4 As shown in the figure, a non-ferrous metal processing inline rolling device according to an embodiment of the present invention includes a rolling support 1 for support, a feed roller 2 for placing the non-ferrous metal to be processed is fixedly installed at one end of the rolling support 1, a continuous rolling roller 3 for rolling the non-ferrous metal material is provided on one side of the feed roller 2, a detection support 4 for support is provided on the side of the continuous rolling roller 3 near the feed roller 2, an adjustable detection slide 5 is fixedly installed inside the detection support 4, a laser range sensor 6 for detecting the thickness of the non-ferrous metal is fixedly installed inside the detection slide 5, the laser range sensor 6 is signal-connected to a PLC control unit for automatic control, the PLC control unit is signal-connected to a laser displacement sensor 7 for detecting the position of the detection slide 5 and an auxiliary rolling seat 8 for sliding adjustment, an auxiliary pressure roller 9 for auxiliary rolling of the non-ferrous metal thickness is fixedly installed at one end of the auxiliary rolling seat 8.

[0024] Preferably, one end of the calendering support 1 is provided with a connecting groove for supporting the unwinding roll 2 and the continuous calendering roll 3, and a guide roller located between the unwinding roll 2 and the continuous calendering roll 3 is fixedly installed inside the calendering support 1.

[0025] The above technical solution is adopted: the calendering support 1 (steel structure welded and coated with anti-rust paint) has symmetrical connecting grooves at one end to support the rotating shaft of the pay-off roll 2 and the continuous calendering roll 3. The internal welded guide roller (stainless steel material) is located between the pay-off roll 2 and the continuous calendering roll 3, with its axis parallel to the two rolls. The steel structure support is rigid and can withstand the calendering reaction force of the continuous calendering roll 3 without deformation. The anti-rust paint coating is resistant to corrosion in the workshop environment. The high-precision dimensions of the connecting groove ensure the coaxiality of the pay-off roll and the continuous calendering roll, avoiding deviation during non-ferrous metal conveying. The smooth surface of the guide roller reduces friction of non-ferrous metals, prevents scratches on the material surface, and guides the material to be conveyed along a preset path (aligned with the feed inlet of the continuous calendering roll), adapting to non-ferrous metals of different widths.

[0026] Based on the rigid frame support principle, the calendering bracket disperses the calendering load through a welded structure, ensuring stable installation of each roller. The connecting groove, through clearance fit with the roller, enables flexible rotation of the roller. The guide roller, based on the principle of rolling friction, drives the roller to rotate when the non-ferrous metal strip passes through, converting sliding friction into rolling friction and reducing material wear. The position design of the guide roller ensures that the material remains horizontal when entering the continuous calendering roller, avoiding uneven calendering thickness due to angular deviation. During installation, the shafts of the pay-off roller 2 and the continuous calendering roller 3 are embedded into the connecting groove of the calendering bracket 1, achieving rotational connection through bearings. The two ends of the guide roller are fixed inside the bracket through bearings, and its height is adjusted so that its surface is flush with the feed inlet of the continuous calendering roller. During production, the pay-off roller releases the non-ferrous metal strip to be processed, and the strip is guided by the guide roller and smoothly conveyed to the continuous calendering roller 3. During the calendering process, the bracket continuously supports each roller, and the guide roller rotates synchronously with the strip to avoid material wrinkling. The wear of the bearings in the connecting groove is checked regularly, and the oil stains on the surface of the guide roller are cleaned.

[0027] Preferably, in any of the above schemes, the detection bracket 4 is fixedly installed inside the calendering bracket 1, the detection bracket 4 is located on one side of the guide roller, and the detection bracket 4 has an active groove inside to guide the detection slide 5.

[0028] The above technical solution is adopted: the detection bracket 4 (made of stainless steel) is fixed to the inside of the rolling bracket 1 by bolts, located on the side of the guide roller close to the continuous rolling roller 3. An movable groove is opened inside to provide sliding guidance for the detection slide 5. The stainless steel detection bracket is resistant to corrosion by non-ferrous metal processing coolant. The bolt fixing ensures a firm connection with the rolling bracket 1. A smooth coating is set inside the movable groove to reduce the sliding resistance of the detection slide and avoid metal wear. The length of the movable groove is adapted to the width of the non-ferrous metal. The groove is perpendicular to the guide roller to ensure that the moving direction of the detection slide is consistent with the width direction of the material, so as to realize the full width thickness detection.

[0029] Based on the principle of linear guidance, the movable groove is limited to moving only along the width direction of the material through sliding engagement with the detection slide 5, ensuring that the detection path of the laser rangefinder 6 covers the full width of the material. The wear-resistant layer, based on the characteristics of low-friction material, reduces sliding friction loss and extends the service life of the movable groove. The fixed position design of the detection bracket 4 avoids the impact of rolling vibration on the detection accuracy. When installing the detection bracket 4, it is calibrated with a level to make it perpendicular to the guide roller, and the bolts are fixed with the preload. The detection slide 5 is then embedded into the movable groove to ensure smooth sliding. Before production, the movement of the detection slide along the movable groove is controlled according to the width of the non-ferrous metal, so that the laser rangefinder 6 covers the edge of the material. During the rolling process, the detection slide drives the sensor to move back and forth along the movable groove to detect the material thickness in real time. During maintenance, the cover plate on one side of the detection bracket can be removed to clean the metal debris in the movable groove.

[0030] Preferably, in any of the above embodiments, the detection slide 5 includes a drive motor 51 connected to the PLC control unit, a drive screw 52 for transmission, and a slide 53 for support. The drive motor 51 is fixedly installed inside the detection bracket 4. The output end of the drive motor 51 is fixedly installed with the drive screw 52 that rotates inside the detection bracket 4. The surface of the drive screw 52 is threadedly connected to the slide 53 that moves inside the detection bracket 4. The two ends of the top of the slide 53 are fixedly installed with sealing films for sealing and protection.

[0031] The above technical solution is adopted as follows: the drive motor 51 (servo motor, connected to the PLC control unit signal) of the detection slide 5 is fixed to one end of the detection bracket 4, and the output end is connected to the drive screw 52 through a coupling. The drive screw is threadedly connected to the slide 53. The top two ends of the slide are bonded with sealing films (nitrile rubber material), which fit the top of the movable groove of the detection bracket 4. The servo motor has high driving precision and can control the slide 53 to move accurately along the movable groove, adapting to different detection frequency requirements. The high-precision thread of the drive screw ensures that the slide moves smoothly and avoids damage to the screw thread. The slide is made of lightweight material to reduce the load on the drive motor. The sealing film can prevent metal debris and coolant from entering the movable groove, protecting the drive screw and the slide and reducing failure.

[0032] Based on the screw drive principle, the drive motor drives the drive screw to rotate. The screw meshes with the sliding seat nut, converting the rotational motion into the linear motion of the sliding seat. The PLC control unit controls the motor speed and direction by sending pulse signals, realizing the reciprocating movement of the sliding seat. The sealing film, based on the elastic sealing principle, forms a dynamic seal by tightly adhering to the top of the movable groove. It deforms synchronously with the movement of the sliding seat, blocking impurities. Before production, the operator sets the movement range of the detection sliding seat 5 through the PLC control unit. After startup, the drive motor 51 drives the drive screw 52 to rotate, and the sliding seat 53 moves along the movable groove. Laser ranging sensor... Device 6 synchronously detects the thickness of non-ferrous metals. When it moves to the endpoint, the PLC controls the motor to reverse, realizing reciprocating detection. During the calendering process, the sealing film moves with the sliding seat to prevent debris from entering the moving groove. After the detection is completed, the sliding seat returns to the initial position. The drive screw is cleaned regularly, lithium-based grease is applied, and the wear of the sealing film is checked. The PLC uses a PID algorithm to adjust the pulse frequency of the drive motor based on the feedback value of the laser displacement sensor 7 and the set position to ensure movement accuracy. The sliding seat is set with overload protection to avoid jamming that could burn out the motor. The preload of the drive screw is detected by a torque wrench, and the bearing seat is adjusted if it exceeds the tolerance.

[0033] Preferably, in any of the above schemes, the laser rangefinder 6 is fixedly installed at the bottom of the sliding base 53, and the laser displacement sensor 7 is fixedly installed at one end of the sliding base 53 and located inside the detection bracket 4, with the laser displacement sensor 7 located below the sealing film.

[0034] The above technical solution is adopted as follows: the laser rangefinder 6 (laser triangulation method, signal connected to the PLC control unit) is fixed at the bottom of the sliding seat 53, with the detection end vertically downward aligned with the non-ferrous metal strip; the laser displacement sensor 7 is fixed at one end of the sliding seat 53, with the detection end horizontally facing the scale plate of the detection bracket 4, located below the sealed film. The high precision of the laser rangefinder 6 can accurately detect the thickness of the non-ferrous metal, and the high sampling frequency captures the thickness fluctuation of the material along the length direction, providing accurate data for auxiliary rolling. The high protection performance is suitable for workshop dust and coolant environments. The laser displacement sensor 7 monitors the position of the sliding seat 53 in real time to ensure that the laser rangefinder 6 detects according to the preset path and avoids missed detection. The sensor is located below the sealed film to prevent the film from blocking the detection light path and ensure signal stability.

[0035] Laser rangefinder 6, based on the laser triangulation principle, emits a laser beam onto the non-ferrous metal surface. The reflected light is received by a CMOS camera, and the thickness value is obtained by calculating the light spot offset. This value is then converted into an analog signal and transmitted to the PLC. Laser displacement sensor 7, based on the laser time-of-flight principle, emits a laser beam onto a scale plate. The distance is calculated using the reflected light to determine the position of the sliding block. This data is fed back to the PLC for closed-loop position control. The two sensors work together. The PLC correlates the thickness data with the position data to generate a material thickness distribution map. During production, laser rangefinder 6 moves with sliding block 53, collecting thickness data every 1ms and transmitting it to the PLC. Laser displacement sensor 7 synchronously collects thickness data from the sliding block. The PLC matches the position data with the thickness to determine the thickness deviation in different width areas of the material. If the thickness exceeds the preset tolerance, the PLC triggers an auxiliary rolling action. During the detection process, the sensor provides real-time data feedback, and the PLC displays the thickness distribution curve on the human-machine interface. The laser rangefinder sensor is calibrated periodically with standard gauge blocks, and the laser displacement sensor is calibrated with a standard rangefinder. The PLC uses a digital filtering algorithm to process the laser rangefinder sensor data, remove vibration noise, and set a thickness deviation threshold. When the threshold is exceeded, auxiliary rolling is initiated. The position data of the laser displacement sensor is used to correct the sliding block's movement trajectory. When the deviation exceeds the threshold, the drive motor speed is adjusted. Shielded cables are used for the sensor connection lines to reduce electromagnetic interference.

[0036] Preferably, in any of the above embodiments, the auxiliary calendering seat 8 includes an auxiliary support 81 for connection and fixation, a drive cylinder 82 for signal connection to the PLC control unit, and a calendering auxiliary seat 83 for lifting and adjusting. The auxiliary support 81 is fixedly installed on the top of the sliding seat 53. The drive cylinder 82 is fixedly installed on one end of the auxiliary support 81. The output end of the drive cylinder 82 is fixedly installed with the calendering auxiliary seat 83, which moves up and down inside the auxiliary support 81. A laser verification sensor for verification and detection is fixedly installed on one end of the calendering auxiliary seat 83.

[0037] The above technical solution is adopted as follows: the auxiliary bracket 81 of the auxiliary calendering seat 8 is bolted to the top of the sliding seat 53, the drive cylinder 82 (double-acting cylinder, connected to PLC signal) is fixed to the top of the auxiliary bracket, and the output end is connected to the calendering auxiliary seat 83 (aluminum alloy material) with the output end facing down. A laser verification sensor (laser reflection type) is fixed to one end of the calendering auxiliary seat 83, and the detection end is aligned with the auxiliary pressure roller 9 with the detection end facing down. The stainless steel material of the auxiliary bracket is corrosion resistant, and the rigid connection with the sliding seat ensures that the auxiliary pressure roller 9 moves synchronously with the sliding seat. The large thrust of the drive cylinder can provide auxiliary calendering force to adapt to different thickness deviation correction requirements. The aluminum alloy material of the calendering auxiliary seat is lightweight, reducing the load on the sliding seat. The laser verification sensor detects the distance between the auxiliary pressure roller 9 and the guide roller in real time to ensure accurate calendering thickness and avoid over-calendering that causes the material to become thinner.

[0038] Based on the pneumatic drive principle, the drive cylinder uses compressed air to push the piston rod to extend and retract, causing the rolling auxiliary seat 83 to rise and fall, adjusting the distance between the auxiliary pressure roller 9 and the guide roller, thus achieving assisted rolling of non-ferrous metals. A laser calibration sensor detects the position of the auxiliary pressure roller and feeds the distance data back to the PLC. The PLC calculates the required rolling amount based on the thickness data from the laser distance sensor 6 and controls the pressure of the drive cylinder (pressure is positively correlated with rolling amount). The structural design of the auxiliary support ensures that the auxiliary pressure roller and the guide roller axis are parallel, guaranteeing uniform rolling. When the PLC detects that the thickness of a certain area of ​​the non-ferrous metal exceeds the tolerance, it controls the detection slide 53 to move above that area based on the position data from the laser displacement sensor 7, driving... When the cylinder 82 is vented, it pushes the calendering auxiliary seat 83 to descend. The auxiliary pressure roller 9, in conjunction with the guide roller, applies pressure to the material. The laser calibration sensor detects the spacing between the auxiliary pressure rollers in real time, and the data is fed back to the PLC. The cylinder pressure is adjusted until the spacing meets the standard. After calendering is completed, the cylinder exhausts air, the calendering auxiliary seat rises, and the sliding seat moves to the next out-of-tolerance area. The cylinder seals are checked periodically, and the laser calibration sensor is calibrated. The PLC uses closed-loop control. It calculates the required reduction amount based on the thickness deviation value of the laser distance sensor 6, and then adjusts the air intake pressure of the drive cylinder based on the spacing feedback from the laser calibration sensor. The upper limit of the cylinder pressure is set to avoid damaging the material. The pressure-reduction curve is calibrated periodically to ensure calendering accuracy.

[0039] Preferably, in any of the above embodiments, the auxiliary pressure roller 9 includes a drive pulley group 91 connected to the PLC control unit and an extrusion roller 92 that outputs pressure. The drive pulley group 91 is fixedly installed inside the calendering auxiliary seat 83, and the output end of the drive pulley group 91 is fixedly installed with an extrusion roller 92 that rotates inside the calendering auxiliary seat 83. The extrusion roller 92 is located above the guide roller.

[0040] The above technical solution is adopted: the drive pulley group 91 of the auxiliary pressure roller 9 (including servo motor and synchronous pulley) is fixed inside the calendering auxiliary seat 83, and the extrusion roller 92 is fixed at the output end of the drive pulley group and can rotate inside the calendering auxiliary seat. It is located directly above the guide roller (the axial spacing can be adjusted by the drive cylinder). The extrusion roller is made of wear-resistant material. The high hardness ensures no deformation during the calendering process. The smooth surface avoids scratching the non-ferrous metal. The drive pulley group drives the extrusion roller to rotate synchronously (the linear speed is consistent with the speed of the non-ferrous metal strip) to avoid material slippage. The extrusion roller is located above the guide roller to form a counter-pressure structure, which can apply pressure to the local thick area of ​​the material and correct the thickness deviation to within the threshold. It works with the continuous calendering roller 3 to improve the overall calendering accuracy.

[0041] Based on the principle of synchronous transmission and counter-pressure, the servo motor of the drive pulley group receives pulse signals from the PLC and drives the extrusion roller to rotate via the synchronous belt, ensuring that its linear speed matches the strip speed. The counter-pressure area formed by the extrusion roller and the guide roller, by adjusting the spacing and pressure, causes plastic deformation in the thick area of ​​the non-ferrous metal, reducing the thickness to the standard value. The length of the extrusion roller is adapted to the local rolling requirements to avoid over-rolling of the surrounding area. When the auxiliary rolling starts, the PLC controls the servo motor of the drive pulley group 91 to start according to the thickness data of the laser rangefinder 6. The extrusion roller 92 rotates at a speed synchronized with the strip, and the drive cylinder 82 pushes the rolling auxiliary seat 83 to descend. The extrusion roller and the guide roller cooperate to clamp the non-ferrous metal strip and apply a preset pressure. During the rolling process, the extrusion roller rotates synchronously with the strip to plastically deform the thick area. The laser calibration sensor monitors the spacing in real time to ensure accurate rolling thickness. After the rolling is completed, the cylinder drives the extrusion roller to rise, and the drive pulley group stops. The surface of the extrusion roller is polished periodically, and the tension of the synchronous belt is checked. If the tension is insufficient, the tensioning wheel is adjusted.

[0042] The working principle of the inline rolling mill for non-ferrous metal processing according to this utility model is as follows: Before the device starts, the pay-off roller 2 and the continuous calendering roller 3 are fixed by the connecting groove of the calendering bracket 1. The guide roller guides the non-ferrous metal to be processed along a preset path. The PLC control unit initializes components such as the laser range sensor 6 and the laser displacement sensor 7. After starting, the pay-off roller 2 releases the non-ferrous metal strip, which is smoothly conveyed to the bottom of the detection bracket 4 via the guide roller. The drive motor 51 of the detection slide 5 drives the drive screw 52 to rotate, and the slide 53 moves along the movable groove. The bottom laser range sensor 6 synchronously detects the thickness of the strip, and the laser displacement sensor 7 provides real-time feedback on the position of the slide. All data is transmitted to the PLC. If the PLC detects that the thickness of a certain area of ​​the strip exceeds the tolerance, it immediately controls the control. The sliding block moves above the area, and the drive cylinder 82 of the auxiliary calendering block 8 pushes the calendering auxiliary block 83 down. The drive pulley group 91 of the auxiliary pressure roller 9 drives the extrusion roller 92 to rotate, which, together with the guide roller, applies pressure to the out-of-tolerance area. The laser calibration sensor of the calendering auxiliary block detects the distance between the extrusion roller and the guide roller in real time and feeds the data back to the PLC. The cylinder pressure is adjusted to ensure that the calendering thickness meets the standard. The calendered strip continues to be conveyed to the continuous calendering roller 3 to complete the final calendering. The detection slide moves back and forth continuously to detect. The sealing film blocks debris from entering the active groove. All structures work together throughout the process. Through real-time detection and dynamic adjustment, the thickness deviation of the strip along the length direction is reduced, and the calendering quality is improved.

[0043] Compared with the prior art, the present invention has the following advantages: 1. A laser rangefinder 6 for detecting the thickness of non-ferrous metals is installed at the front end of the continuous rolling roll 3 of the non-ferrous metal processing rolling device. The difference in the laser rangefinder value can effectively determine the difference in the thickness of the non-ferrous metals. Based on the difference in thickness, the auxiliary rolling seat 8 drives the auxiliary pressure roll 9 to cooperate with the continuous rolling roll 3 to roll the non-ferrous metals. This increases the auxiliary rolling effect on the thicker parts of the non-ferrous metals, reduces the thickness difference of the non-ferrous metals, and thus reduces the thickness difference along the length direction after rolling, thereby improving the quality of rolling.

[0044] 2. The detection bracket 4 and the detection slide 5 are set to support and adjust the laser rangefinder 6, so that the detection position of the laser rangefinder 6 can be adjusted according to the width of the non-ferrous metal, and the detection position can be precisely controlled by the data feedback of the laser displacement sensor 7.
