[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figures 1 to 5 As shown, the utility model can be implemented through the following embodiments: a self-cleaning papermaking calendering device includes an equipment body 1, an upper pressure roller 2 and a lower pressure roller 3 are installed in the equipment body 1, the upper pressure roller 2 and the lower pressure roller 3 are connected to a motor 4, a cleaning brush 1 5 and a cleaning brush 2 6 are installed in the equipment body 1, the cleaning brush 1 5 is in contact with the upper pressure roller 2, and the cleaning brush 2 6 is in contact with the lower pressure roller 3, a control panel 101 is provided on the equipment body 1, and a forward button 1011 and a reverse button 1012 are provided on the control panel 101.

[0025] The cleaning brush 1 5 is in contact with the upper pressure roller 2, and the cleaning brush 2 6 is in contact with the lower pressure roller 3. When the upper pressure roller 2 and the lower pressure roller 3 rotate with the motor 1 4, the paper scraps and carpet hair remaining on the upper pressure roller 2 and the lower pressure roller 3 are brushed off; the forward button 1011 and the reverse button 1012 on the control panel 101 are used to control the normal operation and cleaning of the pressure rollers, so that the cleaning brush 1 5 and the cleaning brush 2 6 can scrape off and collect the paper scraps and carpet hair adsorbed on the upper pressure roller 2 and the lower pressure roller 3.

[0026] like Figure 1 and Figure 2 As shown, a mounting frame 103 is provided above the device body 1, and a cleaning brush 5 is installed on the mounting frame 103. The setting of the mounting frame 103 facilitates the contact between the cleaning brush 5 and the upper pressure roller 2, and the inclined mounting frame 103 increases the contact area between the cleaning brush 5 and the upper pressure roller 2, thereby improving the cleaning efficiency.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a cleaning area 102 is provided between the lower pressure roller 3 and the device body 1, and a mounting groove 1021 is provided in the cleaning area 102, and a cleaning brush 6 is installed in the mounting groove 1021. The cleaning area 102 is provided for centrally cleaning the swept paper scraps and carpet hair, and a cleaning brush 6 is installed in the mounting groove 1021.

[0028] like Figure 2 As shown, the cleaning brush 1 5 and the cleaning brush 2 6 are respectively provided with a hydraulic telescopic rod 1 501 and a hydraulic telescopic rod 2 601. The installation of the hydraulic telescopic rod 1 501 and the hydraulic telescopic rod 2 601 allows the cleaning brush 1 5 and the cleaning brush 2 6 to be away from or close to the upper pressure roller 2 and the lower pressure roller 3, reducing the wear of the cleaning brush 1 5 and the cleaning brush 2 6 and increasing the service life of the cleaning brush 1 5 and the cleaning brush 2 6.

[0029] like Figure 1 and Figure 3 As shown, a screw rod 7 is provided on one side of the cleaning area 102, the screw rod 7 is connected to a motor 2 701, a moving block 702 is provided on the screw rod 7, and a brush 8 is installed on the moving block 702. The brush 8 reciprocates under the drive of the screw rod 7, so that the brush 8 cleans away the paper scraps and carpet hair scraped by the cleaning brush 1 5 and the cleaning brush 2 6.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a baffle 1022 is installed on the mounting groove 1021. The baffle 1022 is used to prevent the paper scraps and carpet hair scraped by the cleaning brush 1 5 and the cleaning brush 2 6 from entering the mounting groove 1021 when the cleaning program is started. At the same time, after the brush 8 cleans the paper scraps and carpet hair, the baffle 1022 will move the brush 8 so that the brush 8 will shake off the contaminated paper scraps and carpet hair during the return process, thereby improving the cleaning efficiency.

[0031] like Figure 1 As shown, a slide bar 10 is provided at the other end of the cleaning area 102, and a slider 1001 is provided on the slide bar 10, and the slider 1001 is connected to the brush 8. The combination of the slide bar 10 and the slider 1001 is used to cooperate with the moving block 702 and the screw rod 7, so that the brush 8 stably sweeps across the cleaning area 102 to sweep away paper scraps and carpet hair; the slide bar 10 and the slider 1001 simplify the moving structure of the brush 8 and reduce the trouble of maintenance and care.

[0032] like Figure 2 and Figure 4 As shown, a through slot 9 is provided in front of the cleaning area 102, the bottom of the through slot 9 is an inclined surface, a dust hood 901 is installed on the through slot 9, and the dust hood 901 is connected to a vacuum cleaner 902. The through slot 9 is used to accommodate paper scraps and carpet hair cleaned by the brush 8, and the inclined bottom of the through slot 9 is used to suck the paper scraps and carpet hair remaining in the through slot 9 into the vacuum cleaner 902 through the motor vibration and the negative pressure formed by the vacuum cleaner 902, so as to facilitate centralized treatment.

[0033] like Figure 2 and Figure 5As shown, a sealing gasket 11 is installed between the dust cover 901 and the device body 1. The setting of the sealing gasket 11 improves the sealing between the dust cover 901 and the device body 1, and facilitates the vacuum cleaner 902 to form a negative pressure at the dust cover 901, so that the vacuum cleaner 902 can clean the paper scraps and carpet hair in the through groove 9 and the dust cover 901.

[0034] The working principle of the utility model is: start the device body 1, press the forward button 1011 on the control panel 101, the motor 4 drives the upper pressing roller 2 and the lower pressing roller 3 to rotate, the paper passes through the gap between the upper pressing roller 2 and the lower pressing roller 3 and is calendered by the upper pressing roller 2 and the lower pressing roller 3.

[0035] When the cleaning procedure is started, the motor 14 is stopped, the hydraulic telescopic rod 1501 and the hydraulic telescopic rod 2601 are started to extend the cleaning brush 15 and the cleaning brush 26, so that the cleaning brush 15 and the cleaning brush 26 contact the upper pressure roller 2 and the lower pressure roller 3, and the reverse button 1012 is pressed and the vacuum cleaner 92 is started, so that the motor 14 and the motor 2701 are reversed, and the cleaning brush 15 and the cleaning brush 26 brush the stained paper scraps and carpet hair on the upper pressure roller 2 and the lower pressure roller 3 under the brush 8, and the vacuum cleaner 902 sweeps the paper scraps and carpet hair under the brushes. After cleaning, the hydraulic telescopic rod 1501 and the hydraulic telescopic rod 2601 retract the cleaning brush 15 and the cleaning brush 26, stop the motor 14, and then start the motor 2701, the motor 2701 drives the screw rod 7 to rotate, the screw rod 7 drives the brush 8 to move, and the brush 8 sweeps the paper scraps and carpet hair left in the cleaning area 102 into the through groove 9 and is sucked in by the vacuum cleaner 902.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0037] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
