Description
Technical field
The utility model relates to non woven fabric production apparatus field, the wealthy width combing roller of bearing in specially a kind of dead axle.
Background technique
Random web-laying equipment is the important single machine in non-woven cloth production equipment, and has point random web-laying equipment of comb structure then
It is that it represents form.Random web-laying equipment is based on mechanical carding and aerodynamic principle, and the yield of unit breadth is by phase
The restriction of pass has only and increases machine breadth to improve production efficiency.Meanwhile the market also increasingly consumingly wealthy width air lay of demand
The appearance of machine.But due to being architectural limitation, the diameter of random web-laying equipment combing roller cannot increase with the increase of breadth, because
This, for a long time, the breadth of random web-laying equipment is less than always 2400mm because being limited to the rigidity of combing roller, both at home and abroad generally not
It can be outer.Until combing roller is alternatively designed to two sections by someone, just there is the random web-laying equipment of big breadth.
Although big breadth random web-laying equipment occurs, its congenital existing defect annoyings always user, makes its hardly possible
To be promoted.The reason is as follows that: first, three-point support is necessarily used since combing roller is segmentation, although two pairs of combing rollers
Middle bearing is staggeredly arranged, but still locally influences carding effect in bearing position.Second, the combing roller of two pairs of segment designs must
Must combination be mounted in same trabeation, although trabeation itself can be adjusted vertically and horizontally, combing roller it is coaxial
Degree, the mutual gauge of combing roller, each combing roller is to the extremely difficult correction of the gauge of cylinder and adjustment.Third, above-mentioned design, maintainability
It is poor, bearing is replaced, replacement metallic card clothing is all extremely difficult, there must be dedicated lifting appliance.Fourth, being converted when product needs
Fiber dimensious kind, need adapted new metallic card clothing when, unless selecting level needle cloth, be otherwise unable to satisfy every gauge
It is required that this has just greatly limited to the Application Range of needle cloth.In addition, even if being made of expensive carbon fibre material whole
Body combing roller, to avoid segmentation bring defect, but its breadth can not meet the need of mainstream market still no more than 3200mm
It asks.
Utility model content
The shortcomings that the purpose of this utility model is to overcome combing roller segmental structures solves whole combing roller because of rigidity not
Problem that is sufficient and cannot be used for big breadth, using the combing roller structure supported in a kind of dead axle, by the way that roll body is greatly shortened
The distance of supporting-point improves the rigidity of roll body.Under the conditions of same diameter, using the utility model, the breadth of random web-laying equipment
4500mm can be improved.
Realizing the technical solution of above-mentioned purpose is: including hollow roll body, metallic card clothing is wound on roll body, and with sill strip
Edge sealing, the left end of roll body are connected with boring cover, and the right end of roll body is connected with nested trays, and nested trays inner side end has been wholely set cooperation
It is sleeved on the intracorporal circumferential rib of roller, is fastened between roll body and circumferential rib by radial screw, between the end and nested trays of roll body
It is fastened by axial bolt, axial bolt and radial screw are staggered in the circumferential；
It is provided with horizontally disposed dead axle in roll body, first bearing is installed between roll body and dead axle, during dead axle is provided with
Heart through-hole is connected with fixing axle, the protruding boring cover of fixing axle, the central through hole of dead axle right end in the central through hole of dead axle left end
Interior to be equipped with nested transmission shaft by second bearing, the center of the nested trays is connected with the transmission casing through nested trays, institute
It states nested transmission shaft and passes through transmission casing and protruding roll body, nested transmission shaft is mutually matched across transmission casing
Hexagon forms double nested hexagonal coupling torque transferring structures.
Further, the first bearing is two, and is all made of rolling bearing, and two first bearings are arranged at intervals on
Middle part between dead axle and roll body.
Further, be provided on the dead axle of the inside of first bearing limited step, outside dead axle on be set with extension
To the first spacer of dead axle end, it is provided with step surface on the dead axle of the first spacer outer end, the screw thread on high-order step surface
It is connected with the locking nut of the first spacer of locking, is threaded on the step surface of low level and the first locking nut rotation direction phase
Anti- stop nut is connected by screw to as entirety between locking nut and stop nut.
Further, the second bearing is two, and is all made of needle bearing, the nesting between two second bearings
The second spacer has been placed on transmission shaft, is respectively arranged with the limit shaft shoulder on the nested transmission shaft in the outside of two second bearings.
In use, fixing axle is sleeved in the keyed axis hole of side adjustment seat；Nested transmission shaft then passes through rolling bearing
It is supported by other side adjustment seat, the adjustment seat of two sides is attached separately to rack two sides, realizes whole bearing to combing roller and adjusts.
When work, dead axle and fixing axle do not turn, and play the role of supporting roll body jointly with nested transmission shaft, roll body then passes through
The transmitting of nested transmission shaft and nested trays is acted on and is rotated.
Two second bearings of the utility model are arranged at intervals on the middle part between dead axle and roll body, support center away from quilt
It substantially reduces, so the mechanical model of roll body is optimized well, makes the entirety of combing roller that there is very high rigidity.
The utility model solves the problems, such as that whole combing roller cannot be used for big breadth because of insufficient rigidity, uses one kind
The combing roller structure supported in dead axle, improves the rigidity of roll body by the way that the distance of roll body supporting-point is greatly shortened.Identical
Under the conditions of diameter, using the utility model, 4500mm is can be improved in the breadth of random web-laying equipment.
The center of the nested trays of the utility model is connected with the transmission casing through nested trays, and the setting for being driven casing can be with
Increase the contact area of nested trays and nested transmission shaft, guarantees reliable transmission.
The nested trays of the utility model pass through axial bolt respectively and radial screw is connect with roll body, and nested trays can be improved
Bonding strength between roll body guarantees that the torque between nested trays and roll body is transmitted, makes equipment reliability service.
