Abstract

The utility model relates to a half wet three-roller plating press which is arranged on a drying cylinder machine frame. Both ends of a bottom roller, both ends of a middle roller and both ends of a top roller are respectively arranged on a cantilever corresponding to each roller. One side of each cantilever is arranged on an adjusting screw, and the other side is fixed on an upright post. The adjusting screw arranged at the lowest end is arranged on a supporting seat. The utility model drives plating press rollers to run through the retransfer of friction force. The utility model can be used for pressing half wet paper. The utility model not only saves energy, but also produces smooth paper with high intensity and high stiffness.

Description

Half-wet triroller calender

The utility model relates to roll presses for paper industry.

Known roll presses for paper industry is five rollers or more than five rollers, structure is very complicated, in order to make it obtain simplifying, the Chinese patent of application number 8921593.3 has proposed a kind of adjustable offset distance single nip calender, this calender has two felt wrapped rolls, bottom roller is fixed on the portal frame, lean on gear drive between two rollers, top roller lifting and mobile by driving worm screw and gear wheel, a whole set of device such as pinion, though this calender has reduced felt wrapped roll structure is simplified, owing to its transmission is still overlapped complicated mechanism by one, so make that the integral body of equipment is also remarkable, and make also difficult, this calender is the paper after the compacting drying in addition, and has only two pressure rollers, so make the deflection of paper and intensity decrease, and smoothness is not high, this equipment drives each parts running by the cover dynamic structure of itself, therefore, also bigger energy loss will be arranged.

The purpose of this utility model then provides a kind of simple in structure, saves the energy, does not occupy plant area, improves the calender of the smoothness of paper when guaranteeing paper sheet stiffness and intensity again.

The purpose of this utility model is achieved in that this calender comprises three felt wrapped rolls, but by residing position appellation, bottom roller, central roll and top roller also have cantilever, adjust leading screw, supporting seat, handwheel, spanner.And the two ends of the bottom roller of calender, central roll and top roller be contained in respectively with its pairing cantilever on, one side being installed on the adjustment leading screw that handwheel or spanner are housed of each cantilever, another side is fixed on the column, leading screw bottom is contained on the supporting seat.This calender is installed on the drying cylinder, should be contained on the frame of first drying cylinder arbitrary drying cylinder afterwards.

This calender has saved the complicated transmission mechanism of a cover, but the transmission again of leaning on the frictional force between bottom roller and the drying cylinder, and causing each roller to rotate, felt wrapped roll studs with and the identical or different spindle nose of the material of roll body own for the hollow roll two ends.The center line of three felt wrapped rolls can also can divide in two or three vertical planes in same vertical plane.Be on the press polish axle at top paper carrying roll is housed, paper carrying roll can move up and down.

Rely on leading screw, handwheel and spanner in the adjustment component that the position of this calender linear pressure and felt wrapped roll is adjusted, promptly lock after to be adjusted the getting well by the tight parts that are contained on the handwheel, so that fixed-site, for preventing the wrinkling arc spreader bar that on the column of calender, is equipped with of paper web, and the radian of arc spreader bar leans on the screw bolt and nut that is connected with the arc plate to regulate, and bakelite is housed respectively on cantilever and column makees the scraper of blade to keep the cleaning of felt wrapped roll.

The utility model has energy savings, and is simple in structure, do not occupy plant area, carries out press polish because calender is a paper to half wet condition that comes out from drying cylinder, therefore makes paper sheet stiffness intensity that compacting comes out and smooth all more satisfactory.

Be described further below in conjunction with accompanying drawing and embodiment:

Fig. 1 is the structure chart of embodiment 1;

Fig. 2 is the side view (accompanying drawing makes an abstract) of embodiment 2;

Fig. 3 is the transmission principle schematic diagram;

Fig. 4 is the structure chart of the used felt wrapped roll of embodiment 1;

Fig. 5 is an arc spreader bar structure chart;

Fig. 6 is the felt wrapped roll structure chart of embodiment 2.

Embodiment 1,1-5 explanation in conjunction with the accompanying drawings

The bottom roller 1 of calender, the two ends of central roll 2 and top roller 3 all are assembled together with its institute's respective cantilevered 4, the two ends of cantilever 4 respectively with adjustment component in adjustment leading screw 5 and the bearing 11 that is installed on the column 10 be assembled together.The center line of three felt wrapped rolls is contained in the same vertical plane, and the felt wrapped roll roll body is hollow, its structure such as Fig. 3, and the felt wrapped roll roll body adopts the alloy cast iron of high rigidity, and spindle nose 1-1 adopts high-intensity spheroidal graphite cast-iron.

The adjustment leading screw lower end of foot is assemblied on the supporting seat 8, this is equipped with spanner 9 above leading screw, handwheel 6 and locking nut 6-1 are housed on the leading screw 5 of miscellaneous part, two leading screws 5 up and down that close on are mutually connect by same Xiao's axle 12, paper carrying roll 13 is supported by the support 14 that is assemblied on the column 10, and paper carrying roll 13 can move up and down, the scraper 16 that bakelite plate is made for the sheet cutter is housed on column 10, wrinkling for preventing paper web, arc spreader bar 15 is housed on the column 9, and is welded with a plurality of nut 15-1 and bolt 15-2 that are used to regulate its radian under the arc of arc spreader bar 15.

This calender is contained on second drying cylinder frame of paper machine, spanner 9 and 6 pairs of felt wrapped rolls of handwheel of utilizing screw mandrel 5 before use and being contained in above it are regulated, so that keep appropriate linear pressure and appropriate position between the felt wrapped roll, locking nut 6-1 then, bottom roller 1 by and paper machine dryer between frictional force drive and turn round, the transmission of frictionally then causes central roll 2 and top roller 3 to rotate, the paper of half wet condition that come out by first drying cylinder this moment is introduced the top roller 3 of these calenders through paper carrying roll 13, and proceeds oven dry after continue to enter second drying cylinder of paper machine and the 3rd drying cylinder and each drying cylinder of back after central roll 2 and bottom roller 1 press polish.

Embodiment 2: the structure of felt wrapped roll such as Fig. 7 in an embodiment, the felt wrapped roll roll body adopts cast iron, its spindle nose 1-1 adopts steel, the central point O of the cantilever 4 of each felt wrapped roll is installed, distance apart from its fixing point does not wait, and the centerline that makes three felt wrapped rolls is in two vertical planes or three vertical planes of living apart.Other structures are embodiment 1 roughly the same.

Owing to the utility model transmission is that the drying cylinder of pressured smooth roll and the paper machine frictional force when rotating drives, and it is good to produce smoothness, the paper that deflection and intensity are higher, it has again simple in structure, do not increase occupation area of equipment, cheap advantage is so can not only be fit to big factory needs, and can satisfy the needs of middle-size and small-size factory, therefore will bring bigger Social benefit and economic benefit.
