Abstract
The invention provides a forming roll for papermaking squeezing, which can not influence the straightness of a profiling roll due to support shafts and can ensure paper machining. The forming roll comprises two support shafts which are arranged on bearing seats by bearings, the forming roll is sheathed on the support shafts, the two support shafts adopt cantilever beam type, and the forming roll is sheathed at extension ends of the two support shafts.
Description
Technical field
The present invention relates to the press rolls of paper machine technical field, be specially a kind of papermaking squeezing and use format roll.
Background technology
Steps such as the papermaking operation comprises slurrying, modulate, manufacture paper with pulp, and in manufacturing paper with pulp, screening earlier, wet end, squeezing more then; Operations such as oven dry at last, squeezing are exactly l Water Paper to be guided to one with between two moulding rods of felt, the extrusion of mat moulding rod and the water sorption of felt; L Water Paper is done further dehydration; And make papery tightr, to improve paper, gain in strength.Existing moulding rod is seen Fig. 1, and it comprises back shaft 1, and said back shaft 1 is installed on bearing block 3 through bearing 2, and moulding rod 4 is set in back shaft 1.The shortcoming of this structure is: because at work; Be loaded with l Water Paper on the profile shell, the load-carrying of profile shell all is stated from the back shaft, and the back shaft long-term work is crooked because of load easily; And crooked back shaft can have influence on profile shell; And in the paper conversion, the linearity of profile shell requires than higher, otherwise can have influence on the following process of paper.
Summary of the invention
In prior art; Profile shell all is loaded on the back shaft; Because of the bending of back shaft has influence on the linearity of profile shell, and then have influence on the defective of the processing of paper, the invention provides a kind of papermaking squeezing and use format roll; It can not have influence on the linearity of profile shell because of back shaft, guarantees the processing of paper.
Its technical scheme is such: it comprises back shaft; Said back shaft is installed on bearing block through bearing, and the moulding rod is set in back shaft, it is characterized in that: said back shaft has two; Described two back shafts adopt beam type, and said format roll is set in the external part of two back shafts.
It is further characterized in that: it also comprises profile shell; Said profile shell comprises roll body; Silently encapsulation is used at the two ends of said roll body respectively, said silently being set with in the external part of said two back shafts, and the said outside silently is pressed with cover plate and trim ring respectively successively;
Said bearing is a taper roll bearing; Near a side of said roll body, its cycle surface of said bearing contacts with the annular wall of said bearing block inwall, and said bearing seat is a zigzag in the outer face of this side, with the end cap engagement formation labyrinth of its end face indentation of this side; Near the power input side, the opposite side of said bearing, its cycle surface contacts with the labyrinth sidepiece end face of engagement, and the bearing cone end face of this side is through the round nut location, and said round nut is set in said back shaft; The bearing of opposite side; Its cycle surface away from said roll body one side contacts with said trim ring; Said trim ring is set in said back shaft, and the junction of said trim ring and said back shaft is set with felt collar on the said back shaft; The outside end face of said trim ring is connected with capping, and said capping encapsulates the end of said back shaft.
In the said structure of the present invention, adopt two back shafts to support, as long as guarantee that back shaft is concentric; Just can guarantee the linearity and the level of die mould rod, thereby guarantee the operate as normal of die mould rod, and the bearing support structure at two ends and labyrinth structure setting; Guaranteed the normal operation of bearing; And the setting in labyrinth prevents leaking of machine oil, prevents papery by dirty, has further guaranteed the operate as normal of die mould rod.
Description of drawings
Fig. 1 is the structural representation of existing format roll;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 2, the present invention includes back shaft 1, back shaft 1 is installed on bearing block 3 through bearing 2, and moulding rod 4 is set in back shaft 1, and back shaft 1 has two, and two back shafts 1 adopt beam type, and format roll 4 is set in the external part of two back shafts 1; It also comprises profile shell, and profile shell comprises roll body 5, and the two ends of roll body 5 with silently 6 encapsulation, silently 6 are set with in the external part of two back shafts 1 respectively, and silently 6 the outside is pressed with cover plate 7 and trim ring 8 respectively successively; Bearing 2 is a taper roll bearing; Side near roll body 5; Bearing 2 its cycle surfaces contact with the annular wall of bearing block 3 inwalls; The outer face that bearing block 3 is positioned at this side is a zigzag, and with the end cap engagement formation labyrinth of its end face indentation of this side, the setting in labyrinth can prevent leaking of machine oil; And papery has been guaranteed the operate as normal of die mould rod by dirty; Near the power input side, the opposite side of bearing 2, its cycle surface contacts with the labyrinth sidepiece end face of engagement, and the bearing 2 inner ring end faces of this side are through round nut 9 location, and round nut 9 is set in back shaft 1; The bearing 2 of opposite side, its cycle surface away from roll body 5 one sides contacts with trim ring 8, and trim ring 8 is set in back shaft 1; The junction of trim ring 8 and back shaft 1; Be set with felt collar 10 on the back shaft 1, the outside end face of trim ring 8 is connected with capping 11, the end of capping 11 encapsulation back shafts 1.
