Description

Technical Field

[0001] This utility model relates to the field of laser ranging device technology, and in particular to a device for detecting the gap between spacer rollers in an aluminum plate slitting machine. Background Technology

[0002] In the aluminum alloy rolling industry, various aluminum alloy strip shearing machines are used when finished and slit rolled aluminum coils. Currently, commonly used aluminum alloy strip slitting units mainly produce narrow strip aluminum coils of various specifications. During operation, a special disc blade longitudinally cuts wide aluminum foil into narrow strips, and finally, paper or aluminum inner sleeves are used on the winding shaft to complete the slitting process. When the winding machine winds the aluminum strip, it needs to use spacers on the spacer rollers to separate the slitting strips and prevent them from shifting laterally. As the thickness of the aluminum strip gradually increases on the winding rollers, the spacer rollers are gradually raised under the drive arm. During this process, it is necessary to maintain a distance of approximately 10mm between the surface of the spacer rollers and the aluminum strip to avoid scratching and abrasion of the aluminum strip surface caused by the spacer rollers contacting the strip. The traditional method requires workers to be on-site to observe at all times. This method is not only labor-intensive, but also has problems such as low efficiency, slow response, and susceptibility to subjective judgment. It may also increase the risk of human error and make it difficult to guarantee the stability of the production process and the consistency of product quality. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a device for detecting the spacing between spacer rollers in an aluminum sheet slitting machine. It employs a laser rangefinder sensor to detect and control the spacing between the spacer rollers and the aluminum strip in real time, thereby reducing human error.

[0004] The specific technical solution is as follows:

[0005] A device for detecting the spacing of spacer rollers in an aluminum sheet slitting machine includes a movable frame mounted on one side of the take-up roller. The movable frame has hinged arms on both sides, each driven to rotate by a hydraulic cylinder. The upper ends of the two arms are bent together and a transverse beam is provided. Mounting ears are provided on both sides of the beam, and a spacer roller is rotatably mounted between the two mounting ears. Several spacer rings for separating aluminum strips are arranged transversely on the spacer roller. A laser detection device is mounted at the top of the beam. The laser detection device includes a slide rail, a slider, a mounting base, and a laser rangefinder sensor. The slide rail is arranged along the length of the beam. The mounting base is slidably mounted on the slide rail via the slider. The laser rangefinder sensor is mounted on the end of the mounting base near the spacer roller using fasteners. The bottom probe of the laser rangefinder sensor is aligned with the surface of the aluminum strip to measure the spacing.

[0006] Preferably, the laser ranging sensor is located above the spacer roller and the crossbeam frame.

[0007] Preferably, the laser ranging sensor is located between any two spacer rings on the spacer roller.

[0008] Preferably, the measurement direction of the laser rangefinder is perpendicular to the bending direction of the upper end of the support arm.

[0009] Preferably, a locking screw is threaded onto the slider, and one end of the locking screw presses against the slide rail to position the slider.

[0010] Preferably, it also includes a PLC controller, a touch screen, and a servo valve. The PLC controller is electrically connected to the laser rangefinder, the touch screen, and the servo valve. The servo valve is connected to the hydraulic cylinder. When the operator runs the equipment and uses the button to engage the automatic control of the gap between the spacer and the aluminum strip, the laser rangefinder detects in real time and sends the signal to the PLC controller, thereby controlling the servo valve to drive the hydraulic cylinder to raise the outrigger. At the same time, the current gap value and automatic status are displayed on the HMI touch screen.

[0011] The beneficial effects of this utility model are reflected in:

[0012] Using a laser rangefinder sensor to detect the gap between the roller and the aluminum strip in real time can prevent the roller from contacting the aluminum strip. This replaces manual visual inspection and adjustment, which can significantly improve detection accuracy and response speed, reduce human error, and realize the automation and intelligent control of the production process.

[0020] Please see the appendix Figure 2-4 This embodiment provides a device for detecting the spacing between spacer rollers in an aluminum sheet slitting unit. It includes a movable frame 2 disposed on one side of the coiling roller 1, a guide roller 3 disposed on the upper end of the movable frame, and support arms 4 hinged on both sides of the movable frame. The support arms on both sides are driven to rotate by hydraulic cylinders 5 respectively. The upper ends of the support arms 4 are bent and a crossbeam 6 is provided laterally. Mounting ears 7 are disposed on both sides of the crossbeam 6. A spacer roller 8 is rotatably disposed between the two mounting ears 7. The spacer roller 8 is located between the coiling roller 1 and the guide roller 3. Several spacer rings 81 for separating aluminum strips are arranged laterally on the spacer roller 8. A laser detection device 9 is installed at the top of the crossbeam frame 6. The laser detection device 9 includes a slide rail 91, a slider 92, a mounting base 93, and a laser range sensor 94. The slide rail 91 is arranged along the length of the crossbeam frame. The mounting base is slidably mounted on the slide rail 91 via the slider 92. The laser range sensor 94 is installed through one end of the mounting base 93 near the spacer roller 8. The upper and lower ends of the laser range sensor 94 are fixed by fasteners. The bottom probe of the laser range sensor 94 is aligned with the surface of the aluminum strip to achieve spacing measurement.

[0021] In this embodiment, the laser rangefinder 94 is positioned above the spacer roller and the crossbeam frame, and the laser rangefinder 94 is positioned between any two spacer rings 81 on the spacer roller. The measurement direction of the laser rangefinder 94 is perpendicular to the bending direction of the upper end of the support arm 4, thereby aligning the probe of the laser rangefinder 94 with the surface of the aluminum strip.

[0022] In this embodiment, a locking screw 921 is vertically threaded onto the top of the slider 92, and the lower end of the locking screw 921 presses against the slide rail 91 to position the slider 92. The horizontal position of the laser rangefinder 94 can be adjusted by the slider 92 to avoid the problem of the laser rangefinder 94 probe being positioned between the two aluminum strips, which would lead to measurement failure.

[0023] In this embodiment, a PLC controller, a touch screen, and a servo valve are also included. The PLC controller is electrically connected to the laser rangefinder 94, the touch screen, and the servo valve. The servo valve is connected to the hydraulic cylinder. When the operator runs the equipment and uses the button to engage automatic control of the gap between the spacer and the aluminum strip, the laser rangefinder detects the gap in real time and sends the signal to the PLC controller. Simultaneously, the current gap value and automatic status are displayed on the HMI touch screen. When the laser rangefinder 94 detects that the gap is getting closer, it sends a signal to the PLC controller and controls the servo valve to drive the hydraulic cylinder, thereby raising the spacer roller 8. When the laser rangefinder 94 detects that the gap is getting closer, it controls the servo valve to drive the hydraulic cylinder 5, thereby lowering the spacer roller 8.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
