Abstract

The embodiments of the disclosure disclose a doctor-bar adjusting mechanism for a coater, including: a base bracket, an upper plate and a lower plate secured to the base bracket at two ends thereof, a side of a doctor-bar sandwiched between the upper plate and the lower plate, and an other side of the doctor-bar close to a surface of a roller of the coater; the upper plate further comprising an adjusting plate on an upper side thereof, the adjusting plate secured to the base bracket at ends thereof and including a plurality of adjusting devices thereon adapted for adjusting a spacing between the adjusting plate and the upper plate. The implementation of the embodiments of the disclosure may adjust conveniently a spacing between the doctor-bar and the roller and improve the maintenance efficiency and productivity of the coater.

Claims

1. A doctor-bar adjusting mechanism for a coater, comprising:

a base bracket, an upper plate and a lower plate secured to the base bracket at two ends thereof, a side of a doctor-bar sandwiched between the upper plate and the lower plate, and an other side of the doctor-bar close to a surface of a roller of the coater; and

the upper plate further comprising an adjusting plate on an upper side thereof, the adjusting plate secured to the base bracket at two ends thereof and comprising a plurality of adjusting devices thereon adapted for adjusting a spacing between the adjusting plate and the upper plate.

2. The doctor-bar adjusting mechanism according to claim 1, wherein the adjusting plate is a metal plate, the adjusting devices are adjusting bolts disposed penetratingly on the adjusting plate and a top end of the adjusting bolts are against a surface of the upper side of the upper plate.

3. The doctor-bar adjusting mechanism according to claim 2, wherein the base bracket at least comprises two parallel vertical plates, and the upper plate, the lower plate and the adjusting plate are disposed between the two vertical plates and secured to inner sides of the two vertical plates, respectively.

4. A coater, at least comprising a coating liquid dispenser having a nozzle, a roller and a doctor-bar, and further comprising a doctor-bar adjusting mechanism comprising:

a base bracket, an upper plate and a lower plate secured to the base bracket at two ends thereof, a side of the doctor-bar sandwiched between the upper plate and the lower plate, and an other side of the doctor-bar close to a surface of a roller of the coater; and

the upper plate further comprising an adjusting plate on an upper side thereof, the adjusting plate secured to the base bracket at two ends thereof and comprising a plurality of adjusting devices thereon adapt for adjusting a spacing between the adjusting plate and the upper plate.

5. The coater according to claim 4, wherein the adjusting plate is a metal plate, the adjusting devices are adjusting bolts disposed on the adjusting plate and a top end of the adjusting bolts are against a surface of the upper side of the upper plate.

6. The coater according to claim 5, wherein the base bracket at least comprises two parallel vertical plates, and the upper plate, the lower plate and the adjusting plate are disposed penetratingly between the two vertical plates and secured to inner sides of the two vertical plates, respectively.
