Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of rubber roller as shown in Figures 1 to 4, including cylindric roll shaft axis body 1, the diameter of roll shaft axis body 1 is slightly less than
The diameter of the assembly drum for needing to be driven by it or other mold inner-cavities is provided with groove body 2 on 1 circumferential outer surface of roll shaft axis body,
Groove body 2 is set as spiral shape groove body 2, and tubular body 3 is provided on groove body 2, and 3 helical form of tubular body is wound on spiral shape groove body 2,
Tubular body 3 is provided with hollow cavity 4, and cavity 4 is connect with air charging system, and diameter after tubular body 3 is inflated is greater than groove body 2
Highly.By above-mentioned setting, when tubular body 3 loses heart, tubular body 3 is located inside groove body 2, since the diameter of roll shaft axis body 1 omits
Less than the diameter for needing the assembly drum being driven by it or other mold inner-cavities, therefore, assembly drum or mold can be nested into roll shaft
On axis body 1, after being located in place, after being inflated by cavity 4 of the air charging system into tubular body 3,3 volume of tubular body increases, directly
Diameter also increases, and the inner wall of tubular body 3 and assembly drum or mold is made to generate extruding, makes 3 pressing molding of tubular body drum or mold, makes into
Type drum or mold will not produce relative rotation with roll shaft axis body 1, have the function that tensioner and fix.When assembly drum or mold are processed
After the completion, as long as the gas in cavity 4 is discharged, 3 diameter of tubular body is reduced, 3 surface of tubular body and assembly drum or mould inner wall
Separation, assembly drum or mold can unloading so that it is convenient to, fast.
As shown in Figure 1 and Figure 2, in 3 one end of tubular body, i.e., spiral shape groove body 2 is arranged in the one end sealed in tubular body 3
In order to which one end of tubular body 3 is fixed fixing sleeve 5 is arranged in the end of spiral shape groove body 2, fixing sleeve 5 is tubulose in one end
One end of body 3 is fixed in groove body 2.Fixed part 6 is set between fixing sleeve 5 and one end of roll shaft axis body 1, is such as connected by screw thread
It connects, or the mode of engaging is fixed on roll shaft axis body 1.
As shown in Figure 1 and Figure 2, roll shaft spindle nose 7 is set in the other end of roll shaft axis body 1, through-hole is set in roll shaft spindle nose 7
8, through-hole 8 is connected to one end of spiral shape groove body 2；In 3 other end of tubular body, i.e. one end of input and output gas, it is threaded through through-hole 8
It is interior, fastener 9 is set in 8 end of through-hole of roll shaft spindle nose 7, one end of the input and output gas of tubular body 3 is fixed on roller by fastener 9
On axis spindle nose 7, air inlet 10 is set in 8 end of through-hole of roll shaft spindle nose 7, rotary joint 11, inflation are set on roll shaft spindle nose 7
Device is connect by rotary joint 11 with air inlet 10.The rubber roller of the utility model, structure is simple, can quickly adjust roll shaft axis
The diameter of body 1, be conducive to it is quickly fixed and loosen cover roll shaft axis body 1 on mold, it is easy to use, it is applied widely.
The utility model embodiment is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
