Description
Technical field
The utility model relates to the technical field of papermaking equipment, the hard calender of especially a kind of paper grade (stock).
Background technology
Papermaking apparatus be paper making combine equipment, primarily of net, pressing and drying etc. part form.Mesh portions cylinder and fourdrinier wire two kinds, press section is made up of pressure roller and papermaker's felt etc., and drying section is made up of one or several drying cylinder.Some fourdrinier also equips calender, to improve the smoothness and tightness etc. of paper.The type of papermaking apparatus is a lot, as manufacture machine glazing paper MG. machine, manufacture paper fourdrinier wire many drying cylinders paper machine, manufacture the thin-paper machine of typing paper and cigarette paper etc., manufacture the board machine etc. of cardboard.
Hard calender is one of machinery very important in papermaking operation, and hard calender is mainly used in the ornamenting being coated with front paper, improves smoothness and reduces thickness difference.But existing hard calender still comes with some shortcomings part in structural design, and after existing hard calender is exerted pressure to paper, the glossiness of paper is poor, causes the good looking appearance degree of finished product paper poor.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, providing a kind of paper grade (stock) hard calender, not only can improve the flatness of paper, can also improve the glossiness of paper.
The utility model solves the technical scheme that its technical problem adopts: the hard calender of a kind of paper grade (stock), comprise fixed installation body in the horizontal plane, the front top of described body is installed with felt wrapped roll, the front center of body is installed with backer roll, the front bottom end of body is provided with the cylinder moved up and down for controlling backer roll, be provided with the heating arrangements being provided for felt wrapped roll heating in body, the rear end of body is provided with can for the guide roller that paper passes through after felt wrapped roll and backer roll are exerted pressure.
Further specifically, described heating arrangements is the logical oily heating arrangements or the electrified regulation mechanism that are built in felt wrapped roll inside.
Further specifically, described backer roll is connected with warm-air pipe or infrared ray governor motion.
Further specifically, between the place straight line of the central point of described felt wrapped roll and the central point line of backer roll and horizontal plane, angulation is 60 ° ~ 90 °.
The beneficial effects of the utility model are: the hard calender of paper grade (stock) of the present utility model has the following advantages:
One, backer roll realizes pressurization by cylinder, and by logical oil or energising, felt wrapped roll is heated, and improves page glossiness, flatness and tightness;
Two, the hot blast on backer roll or infrared ray governor motion can prevent counter tide, and balance web moisture profile, regulates page elasticity, finally improve quality of finished paper.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, body, 2, felt wrapped roll, 3, backer roll, 4, cylinder, 5, paper, 6, guide roller.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the hard calender of paper grade (stock), comprise fixed installation body 1 in the horizontal plane, the front top of described body 1 is installed with felt wrapped roll 2, the front center of body 1 is installed with backer roll 3, the front bottom end of body 1 is provided with the cylinder 4 moved up and down for controlling backer roll 3, is provided with the heating arrangements being provided for felt wrapped roll 2 and generating heat in body 1, and the rear end of body 1 is provided with can for the guide roller 6 that paper 5 passes through after felt wrapped roll 2 and backer roll 3 are exerted pressure.
Wherein, heating arrangements is the logical oily heating arrangements or the electrified regulation mechanism that are built in felt wrapped roll 2 inside, improves page glossiness, flatness and tightness.
Backer roll 3 is connected with warm-air pipe or infrared ray governor motion, can prevents counter tide, balance web moisture profile, regulates page elasticity.
Between the place straight line of the central point of felt wrapped roll 2 and the central point line of backer roll 3 and horizontal plane, angulation is 60 ° ~ 90 °, and the design of such angle is for the ease of carrying out intact being connected with processing apparatus before and after hard calender.
The operation principle of the hard calender of this paper grade (stock) is as follows:
Backer roll 3 realizes pressurization by cylinder 4, and by logical oil or energising, felt wrapped roll 2 is heated, and improves page glossiness, flatness and tightness, and hot blast on backer roll 3 or infrared ray governor motion can prevent counter tide, balance web moisture profile, regulates page elasticity, finally improves quality of finished paper.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
