Preferably, the tensioning cylinder includes ultralow pressure friction cylinder, cylinder end pin, the work of the ultralow pressure friction cylinder
The end of stopper rod is connect by oscillating bearing with swing arm, and the ultralow pressure friction cylinder is equipped with cylinder block, the cylinder end pin
One end connect with cylinder block, the other end is connect with rack.
Preferably, the steel shaft is made of two solid cylinders that diameter is small one and large one, and small column is close to swing arm side.
Preferably, the diameter of the rubber-coated set in small column side of the steel shaft, the small column of the steel shaft is greater than cladding
In the internal diameter of the rubber sleeve in outside, the steel shaft, the rubber sleeve are made up of together interference fit.Interference fit, i.e., according to
By the shrink value of axis and hole, make to generate elastic pressure between piece surface after assembly, to obtain the connection of fastening.Interference is finger-hole
The difference of the size size that subtracts the axis matched be negative.The structure is simple, and alignment is good, can bear biggish axial force, torsion
Square and dynamic loading.
Preferably, the swing arm two sides are equipped with convex block.
Compared with prior art, advantage provided by the utility model is: since swing arm two sides are equipped with limit base, avoiding pine
When foil because swing arm swing it is excessive excessive impact force is formed aluminium foil caused by break foil accident, and limit base is by rubber sleeve cladding steel
Axis composition, rubber sleeve is wear-resisting and deformation restores fast, plays effective buffer function, further alleviates the impact force of idler roller.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figs. 1-2, a kind of idler roller of aluminium foil coating machine, the shaft 1 being arranged on the rack including rack 6, both ends,
Idler roller 5, tensioning cylinder are provided with a pair of of swing arm 2 in the shaft 1, and idler roller 5, swing arm 2 are arranged between a pair of of swing arm 2
Tensioning cylinder is set between rack 6, and rack 6 is equipped with two pairs of limit bases 4, is located at the two sides of two pairs of swing arms 2, the limit
Position seat 4 is made of the rubber sleeve 10 of steel shaft 9 and cladding steel shaft.
The tensioning cylinder includes ultralow pressure friction cylinder 7, cylinder end pin 11, the piston of the ultralow pressure friction cylinder 7
The end of bar is connect by oscillating bearing 3 with swing arm 2, and the ultralow pressure friction cylinder 7 is equipped with cylinder block 8, the cylinder tail
One end of pin 11 and cylinder block 8, the other end are connect with rack 6.
The preferred killed steel of steel shaft 9 is made of two solid cylinders that diameter is small one and large one, and small column is close to swing arm 2 one
Side.The rubber-coated set 10 in the small column side of the steel shaft 9, the diameter of the small column of the steel shaft 9, which is greater than, is coated on outside
The internal diameter of rubber sleeve 10, the diameter of the big cylinder of steel shaft 9 are 5cm, and a height of 15cm, the diameter of 9 small column of steel shaft is 4.5cm, a height of
