Description
Technical field
The invention belongs to paper can former technical field, is related to a kind of paper can forming machine, particularly a kind of paper of improvement
The expander of paper can in jug forming machine.
Background technology
With the development of social economy's high speed, the competition of all trades and professions is also more and more fierce, and packing business is more and more prosperous, uses
Paper products replace the expenditure in the cost that metalwork greatly reduces.Into supermarket it can be seen that the paper can of Long Circle, its appearance print
There is each colored pattern, be respectively provided with shuttlecock, table tennis, biscuit, chocolate etc..Common paper can cylinder by cylinder, cylinder bottom and
Cover form, the simplified abbreviation paper web of paper be by cut the scraps of paper of shaping through cylinder mould determine core seal form.Given birth in the paper web of paper can
It is that first scraps of paper bags is embraced on die body by hinge in production, then seal the scrap (bridge)s of the scraps of paper to turn into paper web.But due to the paper web after sealing
It is too small with cylinder mould outer wall gap, it is difficult to rapidly paper web be drawn off from die wall pull-up, between only expanding between paper web and cylinder mould
Gap, it can just make to unload the smooth quick of a process change.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that in a kind of paper can forming machine of improvement
The expander of paper can, not only there is the function of unloading automatically and take paper can, and the oral size of paper can obtains unification.
The purpose of the present invention can be realized by following technical proposal：Paper can is expanding in a kind of paper can forming machine of improvement
Device, it is characterised in that the present apparatus includes cylinder, connecting rod, curved tablet one, curved tablet two and expanding and shrinking mechanism, above-mentioned cylinder
Cylindrical and its lower ending opening, above-mentioned connecting rod lower end are located in cylinder, and small end stretches out cylinder upper end and is used for that can drive
Its actuator rotated is connected, and above-mentioned expanding and shrinking mechanism is between connecting rod side and curved tablet one and connecting rod opposite side and arc
Between shape tabletting two, when the above-mentioned expanding and shrinking mechanism of link rotatable can make curved tablet one and curved tablet two on the basis of connecting rod it is opposite
Or it is opposite mobile, after link rotatable on the inside of above-mentioned curved tablet one, the outside of curved tablet two and cylinder between formed and paper
The forming cavity that tank matches, the cylinder sidepiece have the material returned hole in bar hole axially penetrated through along it, the forming cavity
There is the material returned ring to match with it, the handle on the material returned ring with protrusion, the handle passes through material returned hole simultaneously at top
Stretch out on the outside of cylinder.
The actuator that drivening rod rotates is servomotor, and servomotor can make control speed, and positional precision is very accurate,
Voltage signal can be converted into torque and rotating speed with drive control connecting rod, and the electric signal received can be converted into electronic
Angular displacement or angular speed output on arbor.Small end stretches out cylinder upper end and is connected with the output shaft of servomotor.Start
Servomotor drivening rod rotates, and expanding and shrinking mechanism carries out one toward cylinder by link rotatable to curved tablet one and curved tablet two
The mobile trend of internal wall extruding, will be expanding without expanding paper can progress in forming cavity, and paper can is frangible after expanding
Take, paper can, which has fraction paper can after expanding and is squeezed, in addition is bonded at cylinder inboard wall, can by handle by material returned ring along
Moved from top to bottom in the material returned hole of bar hole, the paper can for being bonded at cylinder inboard wall is unloaded and taken.
There is material returned spring between the material returned ring and cylinder body bottom, it is above-mentioned under the elastic force effect of above-mentioned material returned spring to move back
Material ring has the trend for above moving to cylinder inner top.Handle on material returned ring is pulled moves down exits forming cavity by paper web
When, material returned spring is stretched, and decontrols the handle on material returned ring, and material returned ring can be automatically fallen back on original by the convergent force of material returned spring
Position.
The material returned ring upper end has some recessed spring bases, and the quantity of the material returned spring is identical with spring base quantity
And position corresponds.Single material returned spring is not used, avoids the elasticity of single material returned spring from not reaching the effect of anticipation, in addition
Single material returned spring is once broken or failure easily influences normal production work.
Material returned cylinder is fixed with the outside of the cylinder, piston rod and the above-mentioned handle of the material returned cylinder are fixedly connected with.Move back
The quantity for expecting cylinder is two, and material returned cylinder is symmetrically connected in two outsides of cylinder, and above-mentioned handle quantity is two, material returned gas
Cylinder is corresponded with handling position and the piston rod of material returned cylinder is connected on corresponding handle, and material returned cylinder reduces material returned ring list
Damage when quickly being retracted by material returned spring to its own, in addition material returned cylinder liberated staff and manually pulled the material returned
Ring handle control material returned ring moves up and down this process, realizes full automation and unloads and takes paper web, that is, improves speed of production, again
Reduce manual labor.
