Description
Technical field
The present invention relates to the offset printing technology field, especially a kind of straight line driving mechanism of bottle cap hectographic printing.
Background technology
In present bottle cap hectographic printing, straight line driving mechanism adopts four kinds of drives structure usually:
First kind is sprocket wheel drive chain drive, and the drive mechanism of sprocket wheel chain is fairly simple, and price is more cheap, buying easily, but ratio of precision is relatively poor, and chain is not long service life, and the printing location is relatively more difficult;
Second kind is that band drives the synchronizing wheel transmission synchronously, and the transmission that synchronizing wheel is with synchronously is also fairly simple, and price is also relatively more cheap, buying easily, but stressed little, the life-span is not long, be subjected to the restriction of synchronous strip length, influence printing quality and precision thereby can produce vibrations in the high-speed motion;
The third drives for straight line cylinder, and the driving of straight line cylinder can only move reciprocatingly, and is subjected to the cylinder travel limits;
The 4th kind is the cam driving, and cam drives the closed cam curves that adopt more, and bearing moves reciprocatingly in cam path, and speed is inhomogeneous, and stroke is short.
Summary of the invention
The objective of the invention is to overcome the various defectives of prior art straight line driving mechanism, the straight line driving mechanism of a kind of transmission accuracy height, accurate positioning, long service life, fireballing novel bottle cap hectographic printing is provided.
For realizing above purpose, the present invention has taked following technical scheme: a kind of straight line driving mechanism of hectographic printing, include frame, be placed in the cam of frame below, be provided with the travelling gear that transmits for power at this cam front end, outer surface top along described cam offers cam curve slot to the bottom, on described frame, also be provided with the trolley group, be provided with slide rail between this trolley group and the frame, it is spaced to be provided with a plurality of maintenances on the bottom surface of described trolley group, with the suitable roller bearing of described cam curve slot, when power is input to described travelling gear, this travelling gear drives cam and rotates, and cam promotes roller bearing and moves in slide rail together with the trolley group.
Cam adopts open constant speed cam curve, and trolley group bottom surface is equipped with roller bearing, can put into cam curve slot, and group is carried out the high-speed straight-line motion thereby the rotation that cam does not stop under the drive of travelling gear promotes roller bearing drive trolley.
Described cam is fixed on behind cam front mounting plate and the cam on the installing plate, and is connected the frame below by cam left side fixed head and the right fixed head of cam.Can well cam be fixed by four installing plates, the protection cam can not received extraneous interference in rotation process.
Described slide rail includes preceding support slot, back support slot, preceding guide plate, rear deflector, and described preceding support slot, back support slot are fixed on the frame, and preceding guide plate, rear deflector are separately positioned on preceding support slot and the back support slot.The unique dragging track of novelty is made up of preceding support slot and back support slot, preceding guide plate and rear deflector, can guarantee strict the moving according to needed movement locus in track of trolley group.
Described trolley group is interconnected to constitute by a plurality of trolleys, and described roller bearing is arranged on the bottom surface of trolley.A plurality of trolleys by from beginning to end together, form the circulation of sealing.
Described trolley includes the trolley plate, is provided with the dolly connecting axle respectively in this trolley plate front and back end portion, and adjacent trolley interconnects by this dolly connecting axle.The structure of this formation trolley group can make things convenient for trolley dismounting, assemble also simply, when damaging appears in certain trolley, need not all to disassemble, and can singlely keep in repair.
Be respectively equipped with spring bearing at described dolly connecting axle two ends, described trolley plate is provided with many locating shafts, at least one locating shaft bottom is provided with guide bearing therein, the side end place of guide plate and rear deflector before described guide bearing leans against, described spring bearing is respectively charged in described preceding support slot and the back support slot and can slides therein.When power is input to described travelling gear, travelling gear drives cam and rotates, cam promotes roller bearing and advances together with the trolley group, spring bearing in preceding support slot and back support slot, keep the doing exercises horizontal motion of dolly group, the side end of guide plate and rear deflector before guide bearing leans against guarantees that dolly beat can not take place by rectilinear motion at the volley.
The present invention compared with prior art has following advantage: the straight line driving mechanism of bottle cap hectographic printing of the present invention can connect a plurality of cams and drive simultaneously how group trolley groups are carried out the repeatedly printing of high speed high position precision; Because the trolley group is to move by the cam path promotion roller bearing generation of cam, thus the transmission accuracy height of this driving mechanism, accurate positioning, speed is fast, and speed is even, and the life-span is long; With the dolly connecting axle a plurality of trolleys are linked together between the trolley group, it is simple in structure, and installation and dismounting, efficiency of assembling height are convenient to maintenance, make easily, and cost is low; The trolley group is moved in the track that preceding support slot and back support slot, preceding guide plate and rear deflector form by guide bearing and spring bearing, and its noise is little, wear and tear little, installation is safe and reliable, function admirable, rational in infrastructure, convenient and practical.
