Abstract
The utility model relates to a hard calendar used for a paper board making production line. The hard calendar is characterized by comprising a machine frame (1), wherein a heating roller (2) and a hydraulic roller (3) are arranged on the machine frame (1), the heating roller (2) and the hydraulic roller (3) are arranged in an up-down parallel mode, scrapers (4) are arranged on the upper portion of the heating roller (2) and on the lower portion of the hydraulic roller (3), and the scrapers (4) are contacted with the surface of the heating roller (2) and the surface of the hydraulic roller (3). The hard calendar can heat surfaces of paper boards through the heating roller, plasticization for the surfaces of the paper boards can be achieved, smoothness of the surfaces of the paper boards is improved, and using requirements of people are met.
Description
Technical field
The utility model relates to a kind of papermaking board assembly line, relates in particular to a kind of hard calender for the papermaking board assembly line.
Background technology
In the past in papermaking plate production process, smoothness for paperboard surface, general is all to improve the smoothness of paperboard surface by the control to the processing of coating and coating process, but for the exigent cardboard of some smoothnesss, such as playing card etc., adopt its surperficial smoothness of these modes still can not satisfy the demands.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hard calender for the papermaking board assembly line is provided, and can improve greatly the smoothness of paperboard surface, satisfies people's user demand.
The purpose of this utility model is achieved in that a kind of hard calender for the papermaking board assembly line, it comprises frame, be provided with warm-up mill and crown control hydraulic pressure roller on described frame, described warm-up mill and crown control hydraulic pressure roller go to upper and lower and are arranged in parallel, be provided with scraper, the Surface Contact of described scraper and warm-up mill and crown control hydraulic pressure roller above described warm-up mill with below crown control hydraulic pressure roller.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model heats paperboard surface by warm-up mill, makes it produce plasticizing, improves smoothness of the surface, thereby satisfies people to the requirement of high-grade playing card.
2, lower roll is crown controlled roll, overcome common felt wrapped roll fixing in high shortcoming, can produce the more consistent high-grade playing card of thickness on whole banner.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
Warm-up mill 2
Crown control hydraulic pressure roller 3
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of hard calender for the papermaking board assembly line, it comprises frame 1, be provided with warm-up mill 2 and crown control hydraulic pressure roller 3 on described frame 1, described warm-up mill 2 and crown control hydraulic pressure roller 3 go to upper and lower and are arranged in parallel, be provided with scraper 4 above described warm-up mill 2 with below crown control hydraulic pressure roller 3, the Surface Contact of described scraper 4 and warm-up mill 2 and crown control hydraulic pressure roller 3 prevents that rubbish from adhering on cardboard.Remove the impurity on surface by movement, prevent scraper scratch roll surface.
When passing between warm-up mill and hydraulic pressure roller, warm-up mill heats paper surface when paper, makes its plasticizing, thereby improves the smoothness of paperboard surface.
Claims (1)
