[0036] The present application provides a paper powder removing device for a paper laminating machine, which includes a frame, a paper unwinding roller 100 and a paper guiding roller 200 arranged on the frame. The external paper 300 is conveyed along the paper unwinding roller 100 towards the paper guiding roller 200. A dust sticking roller 400 and a dust suction roller 500 are also arranged on the frame; the dust sticking roller 400 abuts against the paper unwinding roller 100; the dust sticking surface of the dust sticking roller 400 contacts the upper side of the external paper 300; the dust sticking roller 400 and the dust suction roller 500 share a rotating shaft 600, and the rotating shaft 600 is rotatably arranged on the frame; a first cavity 410 is arranged inside the dust sticking roller 400; a second cavity 510 is arranged inside the dust suction roller 500; the dust suction roller 500 is placed inside the first cavity 410; a number of first through holes 420 are provided on the dust sticking roller 400 and are communicated with the first cavity 410, and a number of second through holes 520 are provided on the dust suction roller 500 and are communicated with the second cavity 510, and the second cavity 510 is conductively connected to an external negative pressure suction system.

[0037] The specific paper powder removing process of the paper powder removing device provided by the present application is as follows: The external paper 300 is conveyed along the paper unwinding roller 100 towards the paper guiding roller 200. The upper side of the external paper 300 is the bonding surface to be laminated. The paper powder removing device is arranged on the frame so that the dust sticking surface of the dust sticking roller 400 can contact the upper side of the external paper 300. When the external paper 300 is conveyed forward, it drives the dust sticking roller 400 to rotate, and the dust sticking surface of the dust sticking roller 400 can stick and remove part of the paper powder on the upper side of the external paper 300 to be laminated. And a first cavity 410 is arranged inside the dust sticking roller 400, and a dust suction roller 500 coaxial with the dust sticking roller 400 is arranged inside the first cavity 410. A second cavity 510 is arranged inside the dust suction roller 500 and is conductively connected to an external negative pressure suction system. Since a number of first through holes 410 are provided on the dust sticking roller 400 and are communicated with the first cavity 410, and a number of second through holes 520 are provided on the dust suction roller 500 and are communicated with the second cavity 510, when the external negative pressure suction system is started, the paper powder on the external paper 300 can be sucked away by the external negative pressure suction system through the first through holes 410 and the second through holes 520, so that the paper powder on the external paper 300 can be completely removed to avoid adverse effects on the subsequent lamination process. Through the form of sleeving the dust sticking roller and the dust suction roller, the device can simultaneously play the roles of dust sticking and dust suction for removing paper powder, and the occupied volume is small. Only a small installation space is required to remove paper powder in two different forms, and the effect is better than that of single dust sticking or dust suction for removing paper powder.

[0038] In some embodiments provided by the present application, the rotating shaft 600 is perpendicular to the conveying direction of the external paper 300. In this embodiment, the rotating shaft 600 can be completely driven by the external paper.

[0039] In some embodiments provided by the present application, the first through holes 420 are evenly spaced on the dust sticking roller 400.

[0040] In some embodiments provided by the present application, the second through holes 520 are arranged at uniform intervals on the dust suction roller 500.

[0041] In some embodiments provided by the present application, it further includes a driving motor, and the output shaft of the driving motor is connected to the rotating shaft 600. Driving the rotating shaft 600 to rotate by the driving motor makes the rotation of the dust sticking roller in the paper dust removing device more stable.

[0042] In some embodiments provided by the present application, the first through hole 420 is one of a circle, a triangle or a square.

[0043] In some embodiments provided by the present application, the second through hole 520 is one of a circle, a triangle, a square and a rectangle.

[0044] The above embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
