Description

Technical Field

[0001] This utility model relates to the field of pressurization device technology, specifically to a pressurization device for bonding laminated glass film. Background Technology

[0002] In the production of laminated glass, the bonding and pressurization of the film and glass is a crucial process that determines product quality. The core requirements are to ensure a tight bond between the film and glass, free of air bubbles, while simultaneously achieving continuous and stable production. Currently, the mainstream bonding and pressurization devices in the industry have the following shortcomings:

[0003] Poor flexibility in pressure adjustment: Traditional equipment mostly uses a fixed-gap pressure roller structure, which cannot flexibly adjust the pressure gap and pressure according to changes in glass thickness and film type. It has low adaptability to the production of laminated glass of different specifications, requiring frequent mold changes or equipment parameter adjustments, resulting in low production efficiency.

[0004] Insufficient transmission stability: Some devices use direct connection transmission for the conveyor roller drive mechanism. After long-term operation, problems such as gear wear and increased transmission clearance are likely to occur, resulting in fluctuations in conveying speed. This, in turn, affects the uniformity of bonding and pressing, leading to quality defects such as localized loose bonding and residual air bubbles. Utility Model Content

[0036] Work process:

[0037] I. Pre-launch preparation phase

[0038] Equipment debugging and parameter setting: The operator starts the equipment self-test program through the control system (such as a PLC control cabinet). The system automatically detects the operating status of the drive motor 7 and the electric push rod 15, as well as the reliability of the connection of each transmission component. According to the thickness of the laminated glass to be processed (such as 5mm + 0.76mm film + 5mm) and the film type (such as PVB film), the bonding pressure parameters are set: the lifting stroke is input through the control module of the electric push rod 15 (such as adjusting the initial gap between the bonding pressure roller 8 and the conveying pressure roller 4 to 12mm), and the speed of the drive motor 7 is set (such as adjusting the conveying speed to 1m / min through frequency conversion control) to ensure that the pressure and the conveying speed are matched.

[0039] Material pretreatment and feeding: The cut glass substrate and film are stacked in the order of "glass-film-glass" to form the blank to be bonded. After checking that the surface of the blank is free of dust, oil and other impurities, it is placed at the feed end of the conveyor roller 4, ensuring that the center line of the blank is parallel to the axis of the conveyor roller 4 to avoid bonding deviation caused by uneven load.

[0040] II. Material conveying and pressurizing bonding stage

[0041] Drive transmission and material conveying: When the operator presses the start button, the drive motor 7 (model Y132M-4) is powered on and starts running. The transmission gear 6 (module 4, number of teeth 25) at its output end drives the transmission disc 5 to rotate synchronously through the transmission chain (model 16A-1). The transmission disc 5 drives the conveying roller 4 to rotate via a key connection. The nitrile rubber coating layer (Shore hardness 60±5A) on the surface of the conveying roller 4 uses friction to move the blank to be bonded along the conveying direction. During operation, the tension wheel (diameter 80mm) automatically adjusts the tension of the transmission chain to prevent chain slippage or skipping of teeth and ensure stable conveying speed.

[0042] Lifting and Pressure Control of the Laminating Pressure Roller: When the front end of the billet enters the pressure zone between the conveying pressure roller 4 and the laminating pressure roller 8, the photoelectric sensor (requires additional configuration and is not mentioned in the original structure) detects the billet signal and feeds it back to the control system. The system triggers the electric push rod 15 (model DT300) to move. The output end of the electric push rod 15 pushes the lifting block 12 down along the lifting port 11 through the connecting seat 16. The sliders 17 (embedded with PTFE wear-resistant layer) at both ends of the lifting block 12 slide in the slide rail 14. At the same time, the guide mechanism 20 on the side wall of the slider 17 plays a role: the telescopic spring 201 (elastic force 50-60N) pushes the universal ball 203 in the universal seat 202 to fit tightly against the inner wall of the slide rail 14, eliminating the sliding gap and ensuring that the lifting block 12 descends smoothly in the vertical direction, avoiding the deviation of the laminating pressure roller 8.

[0043] Continuous pressure bonding: After the bonding pressure roller 8 (rubber-coated layer with Shore hardness 65±5A) descends to the set height along with the lifting block 12, it applies uniform pressure to the blank together with the conveying pressure roller 4 (the pressure is indirectly controlled by the thrust of the electric push rod 15, such as converting a 30kN thrust into bonding pressure). During the continuous movement of the blank between the two rollers, the film is tightly bonded to the glass substrate under pressure, squeezing out air and reducing air bubble residue. During this process, the deep groove ball bearings (models 6208 and 6210) in the rotating seats a3 and b13 ensure that the conveying pressure roller 4 and the bonding pressure roller 8 rotate flexibly, reducing running resistance and avoiding scratches on the blank surface.

[0044] III. Post-Lamination Conveying and Equipment Operation Monitoring

[0045] Finished product conveying and collection: The laminated glass finished product, after lamination, is fed out from the discharge end of the conveying roller 4. The operator or automatic conveying mechanism transfers the finished product to the next process (such as heat curing). During the conveying process, the equipment's speed monitoring module monitors the rotational speed of the drive motor 7 in real time. If speed fluctuations occur, the system automatically adjusts the motor frequency to maintain conveying stability.

[0046] Real-time fault monitoring and protection: During equipment operation, a limit switch (not mentioned in the original structure, requires configuration) limits the lifting stroke of the lifting block 12. When the lifting block 12 descends to its limit position, the limit switch triggers the electric push rod 15 to stop, preventing overload damage to the equipment. Simultaneously, a temperature sensor (requires additional configuration) monitors the surface temperature of the pressure roller. If the temperature becomes too high due to friction (e.g., exceeding 60°C), the system issues an alarm signal and automatically reduces the conveying speed or stops the machine.

[0047] IV. Shutdown and Maintenance Phase

[0048] Equipment shutdown: After a batch of production is completed, the operator presses the stop button, the drive motor 7 stops running, and the conveyor roller 4 stops conveying. Then the electric push rod 15 drives the lifting block 12 to rise to the initial position, the bonding pressure roller 8 separates from the conveyor roller 4, and the equipment enters standby mode.

[0049] Routine maintenance: Regularly maintain the equipment, including: adding grease (such as lithium-based grease) to the transmission gear 6 and chain once a week; checking the wear of slider 17 and slide rail 14, and replacing slider 17 in time if the wear of the PTFE wear layer exceeds 1mm; disassembling guide mechanism 20, cleaning dust and impurities in storage cavity 19, and checking the wear of universal ball 203. If scratches or deformation appear on the surface, replace universal ball 203 and telescopic spring 201 to ensure long-term stable operation of the equipment.
