Description

Technical Field

[0001] This utility model belongs to the field of float glass processing, specifically a float glass defect detection device. Background Technology

[0002] Optical distortion is a crucial technical indicator in float glass quality testing. Optical distortion in float glass refers to the degree of distortion of objects seen through the glass when viewed by a person, caused by unevenness on the glass surface or inhomogeneity of the refractive index within the glass. During float glass production, factors such as poor molten glass quality, uneven molten glass composition, large nodules, streaks, ripples, strings of bubbles, stones, or unreasonable parameters during the forming process can all lead to substandard optical performance of float glass.

[0003] A search revealed a float glass defect detection device in Chinese patent publication number CN215179799U, comprising multiple transport rollers, a light source disposed between two adjacent transport rollers, an observation plate, and a marking mechanism. The light source is positioned below the glass and illuminates upwards, while the observation plate is positioned on the side of the glass away from the light source. The marking mechanism includes a marking rod, an indicator block, a marking block, and a drive rod for moving the marking rod. The indicator block and the marking block are connected to the marking rod. The indicator block is located below the observation plate, and the marking block is located below the glass. The distance between the indicator block and the observation plate is equal to the distance between the marking block and the glass. The light source, the marking block, and the indicator block are located on the same straight line.

[0004] However, the aforementioned detection device cannot adjust the illumination range of the light source according to the width of the glass, and the required light source intensity varies for glass of different thicknesses, making it impossible to adjust according to actual conditions, resulting in limited overall adjustability.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a float glass defect detection device. Utility Model Content

Sleeves 6 are arranged at the bottom of each set of strip plates 5. Sliding shafts 7 slide through the sleeves 6. The top of the sliding shafts 7 passes through the strip plates 5 and is connected to the light source 8.

[0029] The light source 8 slides vertically inside the sleeve 6 via the sliding shaft 7, while the sleeve 6 slides horizontally on the crossbeam 4 via the strip plate 5, allowing the light source 8 to move relatively vertically and horizontally.

[0030] refer to Figure 1 The light source 8 is located between the two sets of conveyor rollers below the conveyor roller group 2.

[0031] This ensures that when the light source 8 illuminates the glass, the conveyor rollers do not interfere with the light source 8.

[0032] refer to Figure 2 and Figure 4 The first adjustment mechanism includes a push plate 9, a limit frame 10 and a moving part. The limit frame 10 is symmetrically arranged on the inner side of the transmission frame 1 below the two sets of crossbeams 4.

One end of each set of through slots 22 is set towards the middle of the transmission frame 1.

[0033] The push plate 9 is driven by the moving part to move along the limit frame 10. During the movement of the push plate 9, the sleeve 6 is pushed through the groove wall of the through groove 22, so that multiple sets of sleeves 6 drive the strip plate 5 and the light source 8 to move along the crossbeam 4, thereby adjusting the irradiation range of multiple sets of light sources 8 according to the width of the glass.

[0034] refer to Figure 2 The moving parts include a horizontal plate 11, a screw 12, a threaded cylinder 13 and a handle 14.

[0035] The screw 12 can be driven to rotate by turning the handle 14, and the screw 12 can drive the push plate 9 to move in the cooperation of the threaded cylinder 13 during the rotation.

[0036] refer to Figure 3 and Figure 4The second adjustment mechanism includes a movable plate 15, a bidirectional lead screw 16, a slider 17, and a connecting rod 18. The movable plate 15 is slidably disposed inside the transmission frame 1. The bidirectional lead screw 16 is rotatably disposed inside the transmission frame 1 and located below the movable plate 15. One end of the bidirectional lead screw 16 passes through the transmission frame 1 and is connected to a throttle 19. Two sets of sliders 17 are connected to the bidirectional lead screw 16 with opposing threads. A connecting rod 18 is rotatably disposed on each of the two sets of sliders 17. One end of each of the two sets of connecting rods 18 is rotatably connected to the two sides of the bottom of the movable plate 15.

[0037] In use, by rotating the throttle 19, the throttle 19 drives the bidirectional lead screw 16 to rotate. During the rotation of the bidirectional lead screw 16, the sliding plate 15 is driven to move vertically through the cooperation of the slider 17 and the connecting rod 18.

[0038] refer to Figure 4 The transmission frame 1 has symmetrically provided limit grooves 20 on both sides inside, and the movable plate 15 is slidably disposed between the two sets of limit grooves 20.

[0039] The moving trajectory of the moving plate 15 is limited by the limiting groove 20 to ensure its moving stability.

[0040] refer to Figure 4 The bottom end of the sliding shaft 7 is provided with a movable wheel 21, and the bottom of the movable wheel 21 is in contact with the movable plate 15.

[0041] The movable wheel 21 is designed so that when the movable plate 15 moves vertically, the sliding shaft 7 can be driven to move vertically by the movable wheel 21, without affecting the horizontal movement of the light source 8.
