Abstract
The utility model discloses a kind of anti-settling copper roller bearings.The anti-settling copper roller bearing includes polypropylene axis, metallic rod, bearing, polytetrafluoroethylene (PTFE) set and wear-resistant sleeve；Wherein, the polytetrafluoroethylene (PTFE) set is sheathed on the surface of the polypropylene axis；The metallic rod is secured transverse to the side of the polypropylene axis；The wear-resistant sleeve is sheathed on the surface of the metallic rod；The bearing is rotatably dispose in the other end of the metallic rod.The utility model has the advantages that prevent that surface from sinking copper, and the metallic rod at the idler wheel both ends have the advantages that it is antiwear.
Description
Technical field
Copper equipment technical field is sunk the utility model is related to pcb board, and in particular to a kind of anti-settling copper roller bearing.
Background technology
The outer surface of the PP roller bearings of heavy copper section in the heavy copper equipment of the pcb board of the prior art is easily rich to accumulate copper ion and makes
The phenomenon that into knot copper, is bad so as to cause making sheet.
Utility model content
The utility model provides a kind of anti-settling copper roller bearing, and the outer surface of the PP axis of the easy knot copper of this roller bearing is coated with one layer and prevents
The only polytetrafluoroethylene (PTFE) set of its surface knot copper, to solve above-mentioned technical problem.
The utility model provides a kind of anti-settling copper roller bearing；Wherein, the anti-settling copper roller bearing include polypropylene axis, metallic rod,
Bearing, polytetrafluoroethylene (PTFE) set and wear-resistant sleeve；Wherein, the polytetrafluoroethylene (PTFE) set is sheathed on the surface of the polypropylene axis；Institute
State the side that metallic rod is secured transverse to the polypropylene axis；The wear-resistant sleeve is sheathed on the surface of the metallic rod；The axis
Hold the other end for being rotatably dispose in the metallic rod.
Preferably, which is stainless steel metal bar.
Preferably, the outer diameter of the polypropylene axis is 2.5~4.5 times of outer diameter of the metallic rod.
Preferably, which is Kynoar wear-resistant sleeve.
The utility model has the following advantages compared with the prior art：
In the utility model, since the outer surface of polypropylene axis is socketed with polytetrafluoroethylene (PTFE) set, the polytetrafluoroethylene (PTFE)
Set is made of polytetrafluoroethylene material, has the advantages that insulation, environmental protection, cleans, is not viscous, can prevent that copper ion exists during electroless copper plating
Polypropylene axis surface deposits, so as to fulfill the purpose for preventing that polypropylene axis surface from generating heavy copper phenomenon；And due to the metallic rod
Outer surface be socketed with wear-resistant sleeve, the wear-resistant sleeve can be effectively prevented the metallic rod, and to occur abrasion in rotation process existing
As the wear rate of metallic rod being reduced, so as to achieve the purpose that the protection metallic rod.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the anti-settling copper roller bearing in the utility model embodiment；
Reference numeral：
1st, polypropylene axis；2nd, metallic rod；3rd, bearing；4th, polytetrafluoroethylene (PTFE) set；5 wear-resistant sleeves.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, in the utility model embodiment, which includes polypropylene axis 1, metallic rod 2, axis
Hold 3, polytetrafluoroethylene (PTFE) set 4 and wear-resistant sleeve 5；Wherein, the polytetrafluoroethylene (PTFE) set 4 is sheathed on the surface of the polypropylene axis 1；
The metallic rod 2 is secured transverse to the side of the polypropylene axis 1；The wear-resistant sleeve 5 is sheathed on the surface of the metallic rod 2；
The bearing 3 is rotatably dispose in the other end of the metallic rod 2.As the intermediate member that polypropylene axis 1 is connected with bearing 3, institute
It states metallic rod 2 modes such as threaded engagement or welding can be used and be fixed on the polypropylene axis 1；Under the action of power source,
The related metallic rod 2 of the meeting of bearing 3 rotates together so that polypropylene axis 1 rotates therewith.In the utility model embodiment, described
Anti-slip cover (not marked in figure) is also arranged between polytetrafluoroethylene (PTFE) set 4 and the polypropylene axis 1；The Anti-slip cover is (in figure not
Mark) in contain woven wire, polytetrafluoroethylene (PTFE) set 4 on the one hand can be prevented to be arranged skidding on the polypropylene axis 1, separately
On the one hand since the connection between polytetrafluoroethylene (PTFE) set 4 and the polypropylene axis 1 more fastens, thus prevent described poly-
The wear phenomenon that tetrafluoroethene covers 4 and skids and generate.
It is in use, described since this anti-settling copper roller bearing is mounted on the heavy copper section in pcb board electroless copper plating equipment
The appearance of polypropylene axis 1 is coated with polytetrafluoroethylene (PTFE) set 44, and the polytetrafluoroethylene (PTFE) set 4 is made of polytetrafluoroethylene material, institute
There is insulation, environmental protection with polytetrafluoroethylene (PTFE) set 4, cleaning, does not glue, copper ion is in polypropylene axis when can prevent electroless copper plating
1 surface deposits, so as to fulfill the purpose for preventing that 1 surface of polypropylene axis from generating heavy copper phenomenon.
Since the left and right sides of polypropylene axis 1 is respectively and fixedly provided with metallic rod 2, the outer surface of the metallic rod 2 is socketed with one
Wear-resistant sleeve 5, the wear-resistant sleeve 5 can be effectively prevented the metallic rod 2 and occur wear phenomenon in rotation process, reduce metallic rod
2 wear rate, so as to achieve the purpose that the protection metallic rod 2.Woven wire has been additionally provided with inside the wear-resistant sleeve 5, so as to
Extend the usage time of wear-resistant sleeve 5, preferably play the purpose for preventing that metallic rod 2 from wearing.Preferably, the metallic rod 2 is not
Steel metal of becoming rusty bar 2, the outer diameter of the polypropylene axis 1 are 2.5~4.5 times of the outer diameter of the metallic rod 2.
A kind of anti-settling copper roller bearing provided above the utility model embodiment is described in detail, used herein
Specific case is set forth the principle and embodiment of the utility model, and the explanation of above example is only intended to help
