Specifically, the device is provided with a frame 310, a coating roller assembly 320 mounted on the frame 310, a glue roller assembly 330 mounted on the frame 310 and located below the coating roller assembly, an adjusting assembly 340 mounted on the frame 310 for adjusting the lifting of the glue roller assembly 330, a first driving assembly 350 mounted on the frame 310 and in driving connection with the coating roller assembly 320, and a second driving assembly 360 mounted on the frame 310 for driving the glue roller assembly 330; the coating roller assembly 320 is driven at a faster speed ratio than the glue roller assembly 330 and the coating roller assembly 320 is driven in the opposite direction to the glue roller assembly 330. The speed ratio of the two can be adjusted through different drives, so that the stability and the reliability of transmission are ensured, and meanwhile, the adjustment and the control are convenient.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
