Abstract
The utility model discloses a four-roll calender for calendering films. The four-roll calender comprises an upper roll, a middle roll and a lower roll in sequence; a front calender roll is arranged beside the upper roll; a mirror roll is arranged at the output end of the lower roll; and a rubber roll is arranged above the mirror roll. The four-roll calender has the characteristics of saving energy and materials and the like.
Description
Technical field
The utility model relates to calender, relates in particular to a kind of four-roll calender of calendered film.
Background technology
At present, the high-grade calender that adopts without the calendered film of scenery with hills and waters line high brightness of existing production adopts 5 roll form usually, adopts the calender of 5 rollers so that energy dissipation is larger.
The utility model content
The purpose of this utility model provides a kind of simple in structure, conserve energy, can produce high-grade four-roll calender without scenery with hills and waters line high brightness calendered film.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of four-roll calender of calendered film, wherein, it comprises the upper, middle and lower roller that is arranged in order, and described top roll is other to be provided with the stack preliminary roller, and described lower roll output is provided with mirror roller, and the mirror roller top is provided with rubber rollers.
Wherein, be provided with between mirror roller and the lower roll to draw and get roller.
Wherein, the described quantity of getting roller of drawing is three groups.
Adopt the four-roll calender of the calendered film of this structure only need to be to the heating of upper, middle and lower roller and mirror roller, compared with having saved a rod in the prior art, thereby saved material and energy has reduced cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
See also Fig. 1, a kind of four-roll calender of calendered film, it comprises be arranged in order upper, in, lower roll 1,2,3, the top roll 1 other stack preliminary roller 4 that is provided with, three groups of being arranged in order of lower roll 3 output settings draw gets roller 7, draw and get the roller 7 other mirror rollers 5 that are provided with, mirror roller 5 tops are provided with rubber rollers 6, film 8 is at first by extruding between top roll 1 and the stack preliminary roller 4, in the process, lower roll 2,3 are transferred to draw and get roller 7, get roller 7 and be transferred between mirror roller 5 and the rubber rollers 6 output after the extruding via drawing again, more than all rollers all drive by the motor that is arranged in the calender.
