[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model provides a vibration damping device for the doctor blade in roller coating, such as... Figures 1 to 3 As shown, it includes a vibration damping plate 52. The upper end of the vibration damping plate 52 is suspended on the crossbeam 4 of the coating machine and the upper end of the vibration damping plate 52 can slide on the crossbeam 4 of the coating machine. The lower end of the vibration damping plate 52 hangs down naturally and is naturally attached to the outer surface of the flexible scraper 2. A counterweight block 51 is provided on the side of the lower end of the vibration damping plate 52 away from the flexible scraper 2.

[0023] In this embodiment, the damping plate is S-shaped, so that the upper end of the damping plate forms a hook for hanging on the crossbeam of the coating machine, and the lower end forms a limiting groove for accommodating the counterweight.

[0024] In this embodiment, a vibration sensor 53 is provided on the upper surface of the damping plate 52. An alarm 6 and a controller 7 are provided on the crossbeam 4 of the coating machine, and the vibration sensor 53, the alarm 6 and the controller 7 are electrically connected to each other.

[0025] In this embodiment, the weight of the counterweight is 200~2000 g.

[0026] In this embodiment, the vibration damping plate is made of stainless steel.

[0027] Specifically, the alarm 6 is a buzzer alarm.

[0028] In this embodiment, the upper end of the vibrating plate 52 can slide left and right on the crossbeam 4 of the coating machine to change its position. By changing the mass of the counterweight 51, the effect of the flexible scraper 2 on the coating roller 3 can be locally changed at any part, thereby eliminating the vibration problem caused by the flexible scraper 2 from time to time.

[0029] In this implementation case, when detecting the vibration value of the flexible scraper 2, if the vibration value is too large, the vibration sensor 53 will transmit the detected vibration signal to the controller 7. After processing the signal, an alarm signal will be sent to the alarm 6, causing the alarm 6 to sound and flash, reminding the staff to take action. This method enables online real-time monitoring, which is low-cost, simple and effective.

[0030] Working Principle: In the photovoltaic glass manufacturing process, a coating roller 3 is used to coat the surface of the photovoltaic glass 1 with a coating solution. The flexible doctor blade 2, which works in conjunction with the coating roller 3, will vibrate from time to time. In this application's roller coating doctor blade vibration damping device, the vibration value of the flexible doctor blade 2 is first detected by a vibration sensor 53. If the vibration value is too high, the vibration sensor 53 transmits the detected vibration signal to the controller 7. After processing the signal, an alarm signal is sent to the alarm 6, causing the alarm 6 to sound and flash, reminding the staff to handle the situation. This method allows for real-time online monitoring, is low-cost, simple, and effective. When the vibration value is too high, the upper end of the damping plate 52 can slide left and right on the coating machine beam 4 to change its position. By changing the mass of the counterweight 51, the effect of the flexible doctor blade 2 on the coating roller 3 can be locally altered at any point, thereby eliminating the vibration problem caused by the flexible doctor blade 2.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
