Description
Technical field
The utility model relates to pulp technology for making paper, specifically a kind of paper machine head box top lip of slice micro-adjustment device.
Background technology
Head box is the key position of paper machine, and it had both affected the speed of a motor vehicle of paper machine, affects again the quality of paper.Thereby it is also one of parts with fastest developing speed on Modern Paper Machine, its be otherwise known as " heart of paper machine ".Raising along with the paper machine speed of a motor vehicle, slurry is ejected into the time shorten of typing on the net to even ten part seconds part second from head box, within the of short duration like this time, hope for success the cross direction ration of paper along paper web overall with uniformity, be ferreted out the good page of evenness, if there is no good head box, the paper of normally producing high-quality is difficult to realize.The head box quality critical is the quality of the upper and lower labial lamina manufacture of its outlet-----, adjustment.
The top lip of slice performance is the key position that affects the head box performance, directly affects shaping evenness and the cross direction ration of page, and top lip of slice is the lath of the stainless steel across whole paper web at head box mouth spray place, and its glacing flatness directly affects the aperture of lip.Because span is larger, top lip of slice is easy to distortion, in order to adjust equably the labial lamina bar, and general interval 100-150mm many governor motions of having arranged equably in whole paper web.Quality fluctuation situation according to paper in production process often need to be regulated the labial lamina bar, but adjusting range is very little, if when general provision was regulated separately a strong point, adjustment amount must not be greater than 0.2mm, for requiring higher head box, during adjusting, each adjustment amount must not be greater than 0.15mm.In order to realize so accurate adjustment, traditional method is to utilize worm-and-wheel gear to realize.Because worm gear, worm screw have larger gearratio, so can realize more accurate adjustment.But there is a very large defect in this mechanism, it is exactly complex structure, due to a cover governor motion will be installed at interval of 100-150mm, a paper machine slurry flowing box tens worm-gear speed reducers that just need to be arranged side by side, due to the locus anxiety, the reductor volume is very little, and required precision is very high, so cost is very high.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, precision is high, cost is low paper machine head box top lip of slice micro-adjustment device is provided.
The technical scheme that the utility model adopts is:
Paper machine head box top lip of slice micro-adjustment device, be evenly distributed on along on the crossbeam of top lip of slice banner direction setting, described micro-adjustment device comprises from the inside to the outside screw rod, adjusting nut and the hold-down nut of socket successively, the surfaces externally and internally of described adjusting nut is provided with screw thread, and the internal thread of adjusting nut and the external screw thread of screw rod is intermeshing, the internal thread of the external screw thread of adjusting nut and hold-down nut is intermeshing, the externally threaded pitch of described adjusting nut is greater than the pitch of internal thread; The end of described screw rod is connected with top lip of slice, hold-down nut is fixed on crossbeam.
The upper surface that is provided with pointer, corresponding hold-down nut on described adjusting nut is provided with the scale of an aperture needle.
Described crossbeam two ends are connected with the head box casing by worm and worm gear.
The beneficial effect that the utility model produces is:
Paper machine head box top lip of slice micro-adjustment device of the present utility model is simple and reasonable, it is little, with low cost to take up room, difficulty of processing is little, be easy to realize; Difference by internal and external threads pitch on adjusting nut, realized that high-precision trace regulates, and should can be reflected in intuitively on the dial of hold-down nut by the trace regulated value, do not needed other accessory structure; Degree of regulation is high, and fine setting makes the top lip of slice linearity in 0.02/1000, reaches the purpose of regulating page cross direction ration deviation, makes the shaping evenness of page good; Very simple and easy during operation, the workman does not need to learn complicated operating process, is easy to use on a large scale and promote.
