[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] Example 1 Please see Figure 1 This utility model discloses an online roller coating device for anti-mildew liquid on glass plates, including: a frame 1, a roller coating assembly, a drying assembly, and a control system.

[0020] like Figure 1 As shown, the frame 1 is a welded gantry-type steel structure that spans the conveyor rollers of the glass production line. The glass sheet 2 passes through this device at a uniform speed under the conveyor of the main rollers.

[0021] The roller coating assembly enables uniform coating of the anti-mildew liquid on both sides of the glass plate 2. The assembly includes an upper sponge roller 3, a lower sponge roller 4, an upper spray pipe 5, a lower spray pipe 6, and a drive motor 21.

[0022] The upper roller section, located above the glass plate 2, has lifting mechanisms 7 symmetrically bolted to both sides of the top of the frame 1. The lifting rod of the lifting mechanism 7 points vertically downwards and is fixedly connected to the cylinder body of a cylinder 8 via a connecting plate. The bearing seat of the upper sponge roller 3 is connected to the end of the piston rod of the cylinder 8. Thus, the lifting mechanism 7 is responsible for coarsely adjusting the height of the upper sponge roller 3 to accommodate glass plates 2 of different thicknesses; while the cylinder 8 is used to perform a rapid lifting action for protection during cracking and to provide constant downward pressure during normal operation to ensure uniform roller coating. The upper sponge roller 3 is a non-powered free roller, its surface made of wear-resistant and corrosion-resistant PVA sponge material, passively rotating by friction with the surface of the glass plate 2.

[0023] The lower roller section located below the glass plate 2: A support plate 9 is horizontally welded to the lower part of the frame 1. An airbag cylinder 10 is bolted to the center of the upper surface of the support plate 9. A lower roller carriage 11 is mounted on the support plate 9 via four adjusting screws 12 with fine-tuning handwheels 13, and is directly supported on the lifting platform of the airbag cylinder 10. The lower sponge roller 4 is fixedly mounted on the lower roller carriage 11 via bearing seats. The drive motor 21 is mounted on the side of the lower roller carriage 11 via a motor seat, and its output shaft is directly connected to the roller shaft of the lower sponge roller 4 via a coupling. By rotating the fine-tuning handwheels 13, the height of the four corners of the lower roller carriage 11 can be finely adjusted to ensure that the lower sponge roller 4 is in parallel contact with the lower surface of the glass plate 2. The fine-tuning handwheels 13 are used to fine-tune the final height position of the lower sponge roller 4 to adapt to glass plates 2 of different thicknesses and ensure uniform contact pressure. The drive motor 21 is used to drive the lower sponge roller 4 to rotate actively, and its speed is controlled and synchronized with the conveying speed of the glass plate 2.

[0024] The upper spray pipe 5 and the lower spray pipe 6 are respectively fixed to the frame 1 about 200mm upstream of the upper sponge roller 3 and the lower sponge roller 4 by brackets, with their spray nozzles facing the glass plate 2. They are connected to the anti-mildew liquid storage tank through pipelines, pumps and valves. A flow meter is installed at the valve port to accurately control the amount of anti-mildew liquid sprayed.

[0025] The drying assembly is used to rapidly cure the anti-mildew liquid film. This assembly includes an upper air knife 14, a lower air knife 15, a fan 16, and a heat exchanger 17. The upper air knife 14 and lower air knife 15 are mounted on the frame 1 via brackets and are located approximately 300mm downstream of the sponge roller, with their air outlets facing the upper and lower surfaces of the glass plate 2, respectively. The fan 16 is a 7.5KW centrifugal fan, and its outlet is connected to the air inlet of a heat exchanger 17 via a duct. The two air outlets of the heat exchanger 17 are then connected to the air inlets of the upper air knife 14 and lower air knife 15 via insulated ducts, respectively. Thus, the ambient air supplied by the fan 16 is heated by the heat exchanger 17, forming a stable hot airflow, which is accelerated through the air knife slits and evenly blown onto the upper and lower surfaces of the glass plate 2, achieving the purpose of rapidly drying the anti-mildew liquid.

[0026] The control system includes a detector 18 for detecting glass plate anomalies and a controller (not shown). The detector 18 is a through-beam photoelectric sensor that emits an alarm signal when it detects glass fragments obstructing the light beam. The detector 18 is mounted on the frame 1 via a bracket, approximately 1 meter upstream of the upper spray pipe 5. The controller is connected via signal cables to the detector 18, the solenoid valves of cylinder 8 and airbag cylinder 10. The controller is also connected to the control terminal of the drive motor and the speed detection unit of the main roller conveyor.

[0027] The controller is configured to: The speed detection unit is a rotary encoder installed on the main roller conveyor, used to detect the roller conveyor speed in real time. The speed detection unit detects the speed of the main roller conveyor in real time and converts it into an electrical signal, which is transmitted to the controller. The controller receives the signal, performs calculations through its internal preset PID control algorithm, and outputs a control signal to the frequency converter of the drive motor 21, thereby dynamically and precisely adjusting the speed of the drive motor 21 to ensure that the linear speed of the lower sponge roller 4 is strictly synchronized with the forward speed of the glass plate 2, achieving uniform coating without slippage.

[0028] Upon receiving an alarm signal from detector 18, the controller immediately sends control signals to the solenoid valves of cylinder 8 and airbag cylinder 10. Cylinder 8 rapidly exhausts and contracts, quickly raising the upper sponge roller 3; simultaneously, airbag cylinder 10 rapidly exhausts, causing the lower roller carriage 11, along with the lower sponge roller 4, to descend rapidly. The upper sponge roller 3 and lower sponge roller 4 quickly detach from the surface of the glass plate 2 within 0.5-1 seconds, effectively preventing broken glass from damaging the roller surface.

[0029] The waste liquid recycling system includes a guide plate 20 inclined below the glass plate 2 and a water collection tank 19 located at the bottom of the frame 1. The bottom end of the guide plate 20 is located above the water collection tank 19. Splashed and flowing waste liquid is collected by the guide plate 20 and flows into the water collection tank 19. The water collection tank 19 is connected to the main supply system of the anti-mildew liquid through a recycling pipeline with a filter screen, realizing the recycling of waste liquid.

[0030] In addition, lifting lugs (not shown) are welded to the top crossbeam of the frame 1 to facilitate the online replacement of the upper sponge roller 3. When the upper sponge roller 3 needs to be replaced, after disconnecting the air and electrical circuits, the hoisting equipment can be used to lift the elevator 7, cylinder 8 and upper sponge roller 3 as a whole using the lifting lugs.

[0031] The bottom of the lower roller trolley 11 is equipped with four universal casters (not shown), which cooperate with the guide rails on the frame 1 to facilitate the online replacement of the lower sponge roller 4. When it is necessary to replace the lower sponge roller 4, the locking mechanism is released, and the entire lower roller trolley 11 can be pulled out from the side of the production line by using the handle.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
