Description
Technical field
The utility model relates to corrugated board manufacturing field of equipment, is specifically related to a kind of transverse cutting unit knife roller device.
Background technology
Transverse cutting unit is, in corrugated board production, corrugated board is laterally cut into a kind of equipment requiring length specification, along with improving constantly of corrugated paper board production line efficiency, higher requirement has been had to the fabric width of transverse cutting unit, the production line of same speed, fabric width productivity gain will increase thereupon, the cutting efficiency and also can improve of corrugated board, thus enhance competitiveness.The fabric width of transverse cutting unit production line is increased to 2200mm from initial 1800mm, then to 2500mm, even arrives larger fabric width.But, after the fabric width increase of transverse cutting unit, higher requirement be there has also been to the rotor assembly of transverse cutting unit, when rotor material is constant, increase fabric width and will reduce the integral rigidity of rotor, when causing high speed cut paper, rotor because cut paper impacts produce elasticity of flexure distortion, can affect cut paper effect thus, cause can't cut paper, even can shorten the service life of blade.
At present, the rigidity improving rotor generally adopts following two kinds of methods: one is strengthen cutter shaft wall thickness; Two is strengthen cutter shaft diameter.Although this two schemes can increase the rigidity of cutter shaft, but, meanwhile too increase the rotary inertia of cutter shaft, thus, namely add load, so must strengthen the power of servomotor and driver, the bearing designation matched, main machine frame also need corresponding increasing, manufacturing cost is increased, is unfavorable for market competition.
Utility model content
The purpose of this utility model is to provide a kind of transverse cutting unit knife roller device, after guarantee fabric width increases, and can to three layers, five layers, seven layers corrugated board at a high speed, accurately, stably cut.
A kind of transverse cutting unit knife roller device, be made up of frame assembly, rotor assembly and axle bearing assembly, described frame assembly comprises the wallboard of both sides and the entablature be arranged on the wallboard of both sides and sill, described rotor assembly comprise rotor and with rotor gear, described axle bearing assembly comprises axle, described axle is fixed on the wallboard of both sides by supporting side plate, axle is provided with the axle block bearing for supporting rotor, the axial location that axle block bearing is realized in axle by end ring; Fixed by fastening bolt between described rotor and rotor gear, rotor gear is supported on the wallboard of both sides by rotor gear-bearing, and carries out axial location by bearing gland tool setting roller gear bearing; Rotor gear described in side with between described axle by thrust bearing cap be arranged on the thrust bearing that thrust bearing covers and be connected, described thrust bearing carries out pretension by round nut to be fixed.
Described axle adopts sturdy filled circles Steel material, overall through modulation treatment, ensures that axle has enough rigidity and wearability to support.
Described axle block bearing adopts needle bearing, is evenly distributed in axle.Can effectively support rotor indeformable, adopt needle bearing mainly for increasing the external diameter of axle, because identical external diameter, needle bearing can be larger than the endoporus of other bearing.
It is interference fit between described axle and described supporting side plate.
It is matched in clearance between described rotor and rotor gear.
Described supporting side plate is by alignment pin and be bolted on wallboard.Can stablize, bearing core shaft exactly.
Described rotor adopts 45 carbon junction steels.Then formed by spiral rotor special machine tool overall processing, eliminate unnecessary material, tool rest, counterweight are directly stayed on rotor, add cutter shaft rigidity.
The endoporus that described rotor is processed by deep-hole boring special equipment effectively coordinates with axle block bearing.
Described rotor gear adopts the accurate roll flute of carburizing steel to process.Gear-wheel gear-ring is beated and can be reached three class precisions, and with rotor precision-fit, mode with bolts connects, and ensures transmission accuracy, and the equipment long-term stability of guarantee uses.
Described rotor gear-bearing adopts NSK needle bearing.Ensure supporting rigidity and the running accuracy of rotor.
The described wallboard of both sides adopts 45 carbon junction steels that 100mm is thick.Form through strict timeliness, Precision Machining, have identical positioning datum.
Described sill adopts 30mm steel plate to be welded.Through strict Ageing Treatment, Precision Machining, accurately can locate the wallboard of both sides, be processed with the datum level identical with wallboard, and convenient installation and guarantee assembly precision, so the location that frame assembly can be precise and stable and supporting.
Advantageous Effects of the present utility model: the utility model adopts the pattern of axle and the supporting of wallboard tool setting simultaneously roll assembly, than the existing pattern only having axle to support rotor assembly, there is higher rigidity, when bearing identical power, the distortion of rotor is less; Under identical hard conditions, this supporting pattern can adopt the rotor assembly of less inertia, and thus, required power of motor will reduce, and energy consumption reduces; The endoporus of rotor adopts the pattern processing of deep-hole boring, easy processing and machining accuracy is high, hole size is consistent, do not need Intermediate Gray step, install simple, axle bearing assembly directly penetrates rotor from one end, solves both sides dead eye in present mode and not easily ensures axiality and install troublesome problem, more easily ensure installation accuracy.Combine above-mentioned, transverse cutting unit knife roller device of the present utility model, after guarantee fabric width increases, also can ensure corrugated board high speed, accurately, stably cut, and energy consumption is low, cost of manufacture is reasonable, is conducive to applying.
