Insufficient accuracy: Manual visual inspection is easily affected by factors such as fatigue and emotions, resulting in a very high rate of missed inspections; 3. High cost: It relies on skilled technicians, and labor costs are rising year by year; 4. Poor adaptability: Traditional inspection frames cannot flexibly adapt to calendering rolls with different diameters (such as φ350-φ600) and lengths (2 meters-6 meters).
[0003] The prior art includes a technology entitled "A Cleaning Device for the Lower Roller of a Calender" with publication number "CN106378328 A".

[0010] The guide rail slider is movable and mounted on the linear guide rail. The linear guide rail and the lifter are respectively fixed on the lift mounting frame. The lifter handwheel shaft is connected to the lifter, and the toothed part of the lifter is screwed through the lifter nut.
[0011] The glass production rolling roll surface inspection device also includes a roll diameter adjustable component, which includes a gantry, a probe height adjustment component, and an adjustment component mounting bracket. The adjustment component mounting bracket fixes the probe height adjustment component to the gantry with bolts.
[0012] The glass production rolling roll surface inspection device also includes an online washable component, which includes a frame, a liquid receiving tank, and a liquid collecting tank.

[0013] The glass production rolling roll surface inspection device also includes an electrical cabinet, a computer, and a control frame, with the electrical cabinet and computer mounted on the control frame.

[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] The glass production calender roll surface inspection device of this utility model involves hoisting the calender roll to be inspected onto an adaptive adjustment component during roll surface inspection. After fixing the calender roll, it can rotate under the drive of a universal joint and a servo motor. Roll surface cleaning is performed through an online washable component. A liquid receiving tank is connected to multiple nozzles, which are close to the roll surface. During cleaning, a pump draws cleaning fluid to clean the roll surface. After cleaning the calender roll surface, automated inspection begins. When the gantry activates the laser probe at the initial point, the calender roll's servo motor also starts simultaneously. The calender roll rotates in coordination with the gantry's movement, allowing the laser probe to take comprehensive pictures of the calender roll surface. These pictures are uploaded to a computer's recognition database. The computer compares the pictures with algorithms in the database to determine if there are defects on the roll surface scanned by the laser probe. Under the computer's intelligent algorithm, an alarm is triggered when a problem is detected on the calender roll surface. Simultaneously, the gantry stops moving forward, the laser probe stops working, and the calender roll stops rotating. After on-site personnel mark the defects, inspection continues, and defects are marked again upon discovery. In this way, a comprehensive inspection of the roll surface can be achieved in one inspection operation, effectively improving work efficiency and replacing manual visual inspection and manual touching of burrs and defects on the surface of the calender roll.

[0034] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0035] As attached Figure 1 -Appendix Figure 8As shown, this utility model is a device for inspecting the surface of a calendering roll in glass production. It includes a calendering roll adaptive adjustment component A. One end of the calendering roll A1 is connected to a driving bearing seat A3 via a bearing, and the other end of the calendering roll A1 is connected to a driven bearing seat A15 via a bearing. A gantry A17 is movably mounted on a gantry guide rail A6. The driven bearing seat A15 is movably connected to a driven bearing seat guide rail A12. A motor A7 is mounted on the gantry A17, and the drive gear of the motor A7 meshes with a rack A11. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. The calendering roll to be inspected is first disassembled and then fixed to the calendering roll adaptive adjustment component A. During fixing, the driving bearing seat A3 and the driven bearing seat A15 can accommodate the installation of the calendering roll A1, and the driven bearing seat A15 can be adjusted relative to the driven bearing seat guide rail A12. This allows calendering rolls A1 of different lengths to be inspected using the calendering roll adaptive adjustment component A of this utility model, improving its applicability. When the motor's gear A9 meshes with the rack A11, the motor A7 rotates, and through the meshing of gear A9 with rack A11, it drives the gantry A17 to move relative to the gantry guide rail A6, so that the laser probe B10 on the gantry A17 moves along the axial direction of the calender roll A1, realizing the movement of the calender roll A1 from one side to the other, and completing the surface inspection. In the specific setup, the bearings A2 at both ends are installed onto the two ends of the calender roll A1. The calender roll A1 is then hoisted and installed onto the drive bearing seat A3. The position of the driven bearing seat A15 can be adjusted on the driven bearing seat guide rail A12 according to the different lengths of the calender roll A1. After the calender roll A1 is installed, the gantry A17, driven by the motor 7 and reduced speed by the reducer 8, scans and inspects the surface of the calender roll A1 from the initial point stroke contact switch 5 until the scanning motion reaches the end point stroke contact switch A13, completing the surface inspection. Then, the gantry A17 is driven by the motor back to the initial point stroke contact switch A5, completing the inspection operation. After inspection, the calender roll A1 undergoes surface defect repair and can then be reinstalled in the calender for use. The glass production calender roll surface inspection device described in this utility model has a high degree of automation, which can effectively improve the inspection accuracy and speed of calender roll surface, reduce human error, improve inspection efficiency, reduce labor costs, adapt to complex environments and calender rolls of different specifications, and effectively meet actual use needs.
[0036] The gantry guide rails A6 are arranged in two parallel rows. Each side of the gantry A17 is movably mounted on the corresponding gantry guide rail A6 via a gantry guide rail slider A10. A driven bearing seat limiter A16 is installed on the driven bearing seat guide rail A12. With this structure, the gantry guide rails A6 can support the gantry A17, and the gantry A17 can be moved as needed for calender roll surface inspection.
[0037] The driven bearing housing A15 is movably connected to the driven bearing housing guide rail A12 via a bearing housing guide rail slider A14. The driven bearing housing A15 and the driving bearing housing A3 are arranged in parallel. An initial point travel contact switch A5 is installed near one end of the gantry guide rail A6, and an end point travel contact switch A13 is installed near one end of the gantry guide rail A6. With this structure, the gantry A17 can move within the range defined by the initial point travel contact switch A5 and the end point travel contact switch A13 to complete the roller surface detection.
[0038] The glass production calendering roll surface inspection device also includes a probe height adjustment component B. A laser probe B10 is mounted on a laser probe mounting plate B9, which is fixed to a lifter nut mounting seat B8. A lifter nut B7 is fixed to the lifter nut mounting seat B8, which is fixed to a guide rail slider B6. This structure allows for convenient and reliable adjustment of the laser probe B10's height for different calendering rolls A1 to meet actual needs. Since the lifter nut mounting seat B8 is fixed to the guide rail slider B6, it can only move up and down relative to the lifter B4 when the lifter rotates, without rotating. Specifically, during operation, rotating the lifter handwheel B3 in different directions causes the threaded structure of the lifter B4 to rotate via the lifter handwheel shaft B2, thereby moving the lifter nut B6 up and down, which in turn raises and lowers the height of the laser probe B10, achieving adjustment.
[0039] The guide rail slider B6 is movably mounted on the linear guide rail B5. The linear guide rail B5 and the lifter B4 are respectively fixed on the lifting mounting frame B1. The lifter handwheel shaft B2 of the lifter handwheel B3 is connected to the lifter B4, and the teeth of the lifter B4 are screwed through the lifter nut B7. The glass production calendering roll surface inspection device also includes a roll diameter adjustable component C. The roll diameter adjustable component C includes a gantry A17, a probe height adjustment component B, and an adjustment component mounting bracket C3. The adjustment component mounting bracket C3 fixes the probe height adjustment component B to the gantry A17 with bolts. During operation, the adjustment component mounting bracket C3 fixes the probe height adjustment component B to the gantry A17 with bolts. When inspecting different calendering rolls A1, the lifter handwheel B3 of the probe height adjustment component rotates, driving the laser probe B10 to move up and down. By changing the height, it matches the calendering rolls A1 with different roll diameters to complete the roll surface inspection, improving the applicability of the inspection device.
[0040] The glass production calender roll surface inspection device also includes an online washable component D, which comprises a frame D1, a liquid receiving tank D2, and a liquid collecting tank D3. The liquid receiving tank D2 is mounted on the frame D1, and the liquid collecting tank D3 is located below the liquid receiving tank D2. In this structure, during the cleaning of the calender roll A1, the cleaned waste liquid drips into the liquid receiving tank D2. Due to the flowability of the liquid, the waste liquid is collected in the liquid collecting tank D3 through the recovery pipe of the liquid receiving tank D2. The cleaning liquid, after being processed by the filtration and separation system, can be recycled and reused multiple times, reducing costs.
[0041] The glass production rolling roll surface inspection device also includes an electrical cabinet E1, a computer E2, and a control frame E3, with the electrical cabinet E1 and computer E2 mounted on the control frame E3.
[0042] The calender roll A1 is connected to the servo drive motor E8 via a universal joint E7. The servo drive motor E8, along with the gantry guide rail A6, the driven bearing seat guide rail A12, the rack A11, and the drive bearing seat A3, are all mounted on the frame D1 of the online washable component D. A protective cover E9 is installed above the servo drive motor E8, on the outside of the frame D1, and on the gantry A17 and the probe height adjustment component B. In this structure, the computer controls the entire device, the electrical cabinet provides power, and the control frame E3 houses the electrical cabinet E1 and the computer E2. The servo drive motor E8 is flexibly connected to the calender roll A1 via the universal joint E7, enabling the calender roll drive. The protective covers E9 on different components provide reliable protection.
[0043] In this invention, when the handwheel shaft and the lifting device are connected, the handwheel shaft and the lifting device output shaft are fixedly connected, and the teeth of the lifting device output shaft mesh with the teeth of the lifting device to realize power transmission.
[0044] The glass production calender roll surface inspection device of this utility model involves first disassembling the calender roll to be inspected, and then fixing it to the calender roll adaptive adjustment component A. During fixing, the active bearing seat A3 and the driven bearing seat A15 can be used to install the calender roll, and the driven bearing seat A15 can be adjusted relative to the driven bearing seat guide rail A12. This allows calender rolls A1 of different lengths to be installed using the calender roll adaptive adjustment component A of this utility model, improving the applicability of the component. The motor gear A9 meshes with the rack A11. During roll surface inspection, the motor A7 rotates, and through the meshing of gear A9 and rack A11, it drives the gantry A17 to move relative to the gantry guide rail A6. This causes the laser probe B10 on the gantry A17 to move axially along the calender roll A1, realizing the movement of the calender roll A1 from one side to the other, completing the surface inspection. In the specific setup, the bearings A2 at both ends are installed onto the two ends of the calender roll A1. The calender roll A1 is then hoisted and installed onto the drive bearing seat A3. The position of the driven bearing seat A15 can be adjusted on the driven bearing seat guide rail A12 according to the different lengths of the calender roll A1. After the calender roll A1 is installed, the gantry A17, driven by the motor 7 and reduced speed by the reducer 8, scans and inspects the surface of the calender roll A1 from the initial point stroke contact switch 5 until the scanning motion reaches the end point stroke contact switch A13, completing the surface inspection. Then, the gantry A17 is driven by the motor back to the initial point stroke contact switch A5, completing the inspection operation. After inspection, the calender roll A1 undergoes surface defect repair and can then be reinstalled in the calender for use.
