Specific implementation mode
Below in conjunction with the accompanying drawings the technical solution of the utility model is further illustrated with embodiment.It is understood that this
The described specific embodiment in place is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for
Illustrate, illustrate only for ease of description, in attached drawing with the relevant part of the utility model and it is not all.
As shown in Figure 1, the utility model provides a kind of unreeling shaft, including support shaft 1, roller 2, bearing 3 and bearing block 4,
Roller 2 is sheathed on the periphery of support shaft 1, and bearing 3 and bearing block 4, axis are both provided between the both ends and support shaft 1 of roller 2
It holds 3 inner ring to be sheathed in support shaft 1, the outer ring of bearing 3 is fixedly connected with the inner ring of bearing block 4, is set on the outer ring of bearing block 4
It is equipped with step surface, the step surface of two bearing blocks 4 is oppositely arranged, and roller 2 is fixed between the step surface of two bearing blocks 4, rolling
The both ends end face of cylinder 2 is abutted with the step surface of two bearing blocks 4 respectively.Preferably, distinguish at 3 both sides of bearing in support shaft 1
It is arranged with clamp spring 8, clamp spring 8 is for positioning bearing 3.
It is arranged support shaft 1 by using roller 2, and the structure of bearing 3 and bearing block 4, Neng Gou are set between
On the basis of ensureing that the appearance and size of unreeling shaft is constant, mitigates the weight of unreeling shaft significantly, reached the light-weighted mesh of unreeling shaft
, and the stressing conditions of unreeling shaft are improved, improve the service life of unreeling shaft.
Further, in the prior art, wire will produce larger phase mutual friction when crossing line on unreeling axle construction
Power easy tos produce concentrated wear and lousiness on unreeling shaft surface, the wire of line was caused also to hold through operation after a period of time
It easily forms surface and locally scratches defect, to reduce the qualification rate of finished metal silk.Therefore in unreeling shaft provided by the utility model
In, it sets support shaft 1 to stainless steel support shaft, sets roller 2 to quartz glass roller, ensured using stainless steel support shaft
The intensity and rigidity of unreeling shaft, the hardness and finish on 2 surface of roller are improved using quartz glass roller, reduce metal
Silk crosses frictional force when line, and 2 surface of roller is not likely to produce local cut and lousiness, crosses line wire and is not easy to form surface part
Defect is scratched, the qualification rate of finished metal silk is improved.
Further, unreeling shaft further includes distal end cap 5 and fixing end end cap 6, and distal end cap 5 and fixing end end cap 6 divide
It is not fixed on the outer ring of two bearing blocks 4, the via passed through for the fixing end of support shaft 1 is provided on fixing end end cap 6.Distally
