Abstract

The utility model relates to the technical field of unwinding devices, in particular to a paper roll unwinding device which comprises an unwinding device body and a cleaning device. The cleaning device comprises a cleaning brush and an electrostatic rod. The cleaning brush and the electrostatic rod are matched with the paper board, so that when the paper board passes through the unwinding device body, the cleaning brush and the electrostatic rod are abutted against the paper board and are positioned on the same side of the paper board. When the film laminating machine is used, the paper board continuously moves and is uncoiled, and then the uncoiled paper board enters the film laminating machine to be laminated. During the moving process of the paper board, the paper board is cleaned by the cleaning brush, so that dust attached to the paper board is loosened. The board is then moved to the position of the electrostatic rod. The static stick sucks away the dust on the cardboard through the effect of electrostatic absorption, and then makes the cardboard cleaner. This also makes the quality after the cardboard gets into the laminating machine tectorial membrane better.

Example (b):

as shown in fig. 1 and 2, the present invention provides a paper roll unwinding device including an unwinding device body and a cleaning device. The unwinding device body comprises an unwinding wheel and a plurality of guide rollers 9. The paper roll 8 is placed on a square winding wheel. The drive motor of the unreeling wheel rotates to unreel the paper roll 8. The paper board 3 discharged from the paper roll 8 enters the film laminating machine after passing through a plurality of guide rollers 9.

The cleaning device comprises a cleaning brush 1 and an electrostatic rod 2. The cleaning brush 1 and the static bar 2 are arranged in a way of matching with the paper board 3, so that when the paper board 3 passes through the unwinding device body, the cleaning brush 1 and the static bar 2 are abutted against the paper board 3 and are positioned on the same side of the paper board 3. And then the cleaning brush 1 cleans the paper board 3 and the electrostatic rod 2 adsorbs the dust on the paper board 3. The electrostatic rod 2 is charged after a plurality of barrel electrodes 4 are charged, so that the electrostatic rod 2 is charged electrostatically.

When the paper roll unwinding device is used, the paper board 3 continuously moves and unwinds, and then the unwound paper board 3 enters the film laminating machine for film lamination. During the moving process of the paper board 3, the paper board 3 is cleaned by the cleaning brush 1, so that the dust attached to the paper board 3 is loosened. Subsequently, the paper sheet 3 is moved to the position of the electrostatic rod 2. The electrostatic rod 2 sucks away dust on the paper board 3 through the electrostatic adsorption effect, and then makes the paper board 3 cleaner. This also makes the quality of cardboard 3 after entering laminating machine tectorial membrane better.

In this embodiment, the paper sheet 3 moves up and down as the paper sheet 3 passes through the cleaning device. The sweeper brush 1 is located in front of the electrostatic wand 2 in the direction of movement of the sheet 3. This enables dust cleaned by the cleaning brush 1 to be effectively adsorbed by the electrostatic rod 2. Meanwhile, dust falling during cleaning by the cleaning brush 1 does not adhere to the paper sheet 3 after the electrostatic rod 2 is adsorbed again.

In this embodiment, the cleaning device further comprises an electrode 4. The electrode 4 is fixedly connected to the frame. The electrostatic rod 2 is in a roller shape. The electrostatic rod 2 is equally divided into three electrostatic strips 21 along its circumferential direction. Each electrostatic strip 21 is isolated from each other. Specifically, adjacent electrostatic strips 21 are separated by an insulating plate. Each electrostatic strip 21 is provided with a connection contact in cooperation with the electrode 4, such that the connection contact is connected with the electrode 4 when the electrostatic strip 21 is rotated to contact the paper sheet 3. And the connecting contacts are disconnected from the electrodes 4 when the electrostatic strip 21 leaves the paper sheet 3. This causes the static strip 21 to become electrostatically charged when in contact with the sheet 3, thereby attracting dust well. When the static strip 21 is far away from the paper board 3, the static strip 21 does not carry static electricity, and the adsorption capacity is lost, so that the static electricity of the static strip 21 is convenient to clean.

In this embodiment, the cleaning device further includes a blade 5. One end of the scraper 5 is abutted against one side of the electrostatic rod 2 far away from the paper board 3. This makes the dust attached to the electrostatic strip 21 be easily scraped off by the scraper 5, thereby ensuring that the dust on the electrostatic strip 21 can be removed in time.

In this embodiment, the squeegee 5 is further provided with an elastic member 6. The elastic member 6 is used to push the squeegee 5 against the electrostatic rod 2. Specifically, one end of the scraper 5, which is far away from the electrostatic rod 2, is hinged to the frame. The elastic piece 6 enables the scraping plate 5 to be tightly attached to the electrostatic rod 2, and therefore dust on the electrostatic rod 2 can be effectively scraped.

In this embodiment, a dust collecting groove 7 is further provided below the scraper 5. The dust collecting groove 7 is used for collecting dust scraped by the scraper 5.

In this embodiment, the cleaning brush 1 is connected to a driving motor so that the rotation direction of the cleaning brush 1 is opposite to the moving direction of the paper sheet 3. Thereby enabling the sweeper brush 1 to better sweep dust on the paper board 3.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
