Abstract
The utility model belongs to the technical field of papermaking machines, and provides a novel breast roll scraper. The novel breast roll scraper is arranged on a rack and on a side surface of a breast roll; a knife and a cover are arranged on the rack; the cover has a sheet structure; the sheet structure is positioned above the knife; a cambered surface of the sheet structure is downward; the knife comprises a blade and a blade mounting plate; the blade is movably connected with the blade mounting plate; a plurality of flow guiding holes are formed in the blade mounting plate; and the blade is in contact with a roll surface of the breast roll. The service life of the blade is prolonged; the blade can be detached quite conveniently; and a phenomenon that the whole scraper is changed is avoided.
Description
Technical field
The utility model belongs to paper machine technology field.
Background technology
Shaped device claims again wet end, is that paper machine is upper most important part, above paper stock suspension, can form page face, and the normal production department of quality of finished paper and paper machine and the operation of building mortion have substantial connection.Once wet web is after building mortion is shaped, the fiber interweaving state in paper is setting substantially just, and the processes such as squeezing subsequently, dry and press polish can only limitedly be improved the web properties being shaped.
Now conventional Web forming apparatus is fourdriner forming device, and it comprises the forming table of the dewatering elements frame holder compositions such as forming net and the breast roll being connected with forming net, forming board, grooved table roll, table roll, dewatering plate, wet suction box, suction flat box.Breast roll is first roller of fourdrinier forming device, and its effect is support forming net and dehydration.Breast roll is that thin plate rolls and forms hollow tubular structure, on the spindle nose of breast roll, rolling bearing is installed, and rolling bearing coordinates with bearing block.In order to prevent that paper pulp from entering between breast roll and forming net, cause the paper pulp on forming net to dewater, plastics or the wooden clean roll surface of scraper can be installed on the roll surface of breast roll.But the reflection of some producers, a large amount of plain boiled waters that flow out from forming board impact on breast roll scraper, scraper for a long time continuously the plain boiled water higher with temperature contact easily and deform.
Utility model content
The utility model is intended to provide a kind of novel breast roll scraper of not yielding, long service life.
The purpose of this utility model can reach by following measures: novel breast roll scraper, be arranged in the frame of side of breast roll, in frame, be provided with cutter hub and cover body, cover body be positioned at cutter hub top and for cambered surface towards under thin-slab structure, this cutter hub comprises blade, blade installing plate, blade is with blade installing plate for being flexibly connected, and blade installing plate is provided with some pod apertures, and blade contacts with the roll surface of breast roll.
Technique scheme difference with the prior art is: the top of cutter hub is provided with cover body, and this cover body is the ventricumbent thin-slab structure of arc, the most of plain boiled water leaking down on forming net is blocked by cover body, a small amount of plain boiled water flows on the cutter hub of below, thereby flow out at the pod apertures place on part plain boiled water blade installing plate, only have very small amount of plain boiled water to splash on blade, make blade remove the impact of plain boiled water from, not yielding, extended the service life of blade, and blade with blade installation kit for being flexibly connected, removal of inserts easily, avoided changing the trouble of whole scraper.
Further, described blade is that Tenon is connected with blade installing plate, dismantles convenient.
Further, described blade for being threaded, connects more firm with blade installing plate.
Further, the junction of described blade and blade installing plate is provided with triangle stiffener, strengthens the firmness that blade is connected with blade installing plate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model breast roll scraper embodiment.
The specific embodiment
With reference to Fig. 1, novel breast roll scraper, be arranged in the frame of side of breast roll 5, be provided with cutter hub and cover body 1 in frame, cover body 1 is positioned at the top of cutter hub, cover body 1 is for thin-slab structure and have the cambered surface to lower convexity, cutter hub comprises blade 2, blade installing plate 3, in embodiment 1 on blade 2 with dovetail projection, on blade installing plate 3 with dovetail groove, blade 2 is connected with blade installing plate 3 Tenons, between blade 2 downsides and blade installing plate 3, is fixed with triangle stiffener 7.On blade installing plate 3, have some pod apertures 4.
During use, breast roll 5 rotates under the drive of wite roll, the raw support paper pulp of forming net 6 contacting with breast roll 5, plain boiled water leaks down from forming net 6, and most of plain boiled water is blocked by cover body 1, and a small amount of plain boiled water flows on the cutter hub of below, thereby flow out at pod apertures 4 places on part plain boiled water blade installing plate 3, only have very small amount of plain boiled water to splash on blade 2, make blade 2 remove the impact of plain boiled water from, not yielding.Breast roll 5 rotates, and blade 2 scrapes the paper pulp on breast roll 5 roll surfaces.
Embodiment 2 as different from Example 1 blade 2 and blade installing plate 3 is bolted.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
