Description
Technical field
The utility model belongs to mechanical equipment technical field, is specifically related to a kind of biaxial tension PTFE stuffing materials sintering roller.
Background technology
The stretched polytetrafluoroethylene material at high temperature has shrinkage, thereby need give and certain force of strain at its shrinkage direction during sintering.For example when thermal finalization longitudinal stretching film, unreel device and coiler is given and the film tensile force by front and back, avoid under the high temperature it to shrink vertically producing.
The biaxial tension PTFE stuffing materials is layering by the multilayer biaxially oriented film and holds sintering and become one.Just as the longitudinal stretching film at high temperature vertically can produce contraction, the at high temperature two-way meeting of biaxially oriented film was shunk simultaneously.And plural layers shrink simultaneously, and its convergent force is very big.
United States Patent (USP) 5964465 has been introduced a kind of roller that prevents that biaxially oriented film from shrinking, it is the long draw point of uniform 13mm on the girth at roller two ends, when film holds on the roller, on the thin-film width direction, give its tension force with hand, draw point is thrust in its edge tension, just can avoid its contraction horizontal in sintering process with the draw point fixed film.
The polytetrafluoroethylene (PTFE) product has notch effect, be that the somewhere has individual breach, product will prolong this breach and tear apart, thereby above-mentioned roller improper use, will cause film to produce when thrusting draw point and tear, draw point can't fixed film, when the pinprick that leaves at film surface of draw point can cause sintering in addition, convergent force can be bigger and bigger with pinprick, so also can't play the effect of fixed film.
In sum, need a kind of film surface that neither damage allow the generation notch effect, film can be fixed preventing the biaxial tension PTFE stuffing materials sintering roller that shrinks again.
Summary of the invention
The purpose of this utility model is to provide a kind of biaxial tension PTFE stuffing materials sintering roller that can effectively prevent film two-way contraction at high temperature.
The biaxial tension PTFE stuffing materials sintering roller that the utility model proposes, form by cylindrical shell 1, volume film rod 2, baffle plate 3, clips 4, dovetail groove 6, abaculus 8, wherein, cylindrical shell 1 is the hollow cylindrical structure in middle part, be provided with central shaft 11 in the cylindrical shell 1, baffle plate 3 is two, be cirque structure, lay respectively at cylindrical shell 1 two ends, the axle that central shaft 11 stretches out baffle plate 3 outside two ends is provided with screw thread 5, screw thread 5 structure matching on the internal thread of gravity flow screen 4 and the central shaft 11, gravity flow screen 4 are screwed into screw thread 5 places at central shaft 11 two ends, are used for fastening baffle plate 3; Cylindrical shell 1 outer wall has dovetail groove 6 vertically, and abaculus 8 is positioned at dovetail groove 6, and is fixed in the dovetail groove 6 by nut 10; Volume film rod 2 is positioned at cylindrical shell 1 one sides, and its two ends can be fixed on the baffle plate 3 respectively.
In the utility model, wide on the groove of dovetail groove 6 is 50mm～80mm, and wide under the groove is 40mm～20mm, and groove depth is 40mm～60mm,
In the utility model, the length of cylindrical shell 1 all leaves the width more than the 100mm less than the width of film to guarantee film both sides outside cylindrical shell 1.
In the utility model, dovetail groove 6 both sides are provided with dentate stripe 7.
In the utility model, abaculus 8 both sides are provided with dentate stripe 9.
In the utility model, the outside diameter of baffle plate 3 is greater than the diameter that holds roller behind the film, and interior circular diameter is greater than the diameter of drum shaft.
In the utility model, the diameter of volume film rod 2 is 5mm～20mm, and length equals the length of roller.
In the utility model, the effect of dovetail groove 6 and abaculus 8 is: in multilayer or single thin film embedded groove, when screwing nut 10, when abaculus 8 embeds in the dovetail groove 6 gradually, the clamping force of 8 pairs of films of abaculus also increases gradually, the striped 7 in the dovetail groove 6 and the striped 9 of abaculus 8 can prevent that film from skidding off in groove, avoid film vertically producing contraction.
In the utility model, the effect of volume film rod 2 is: the film of fixed rear portion prevents that it from vertically producing contraction, holding the number of plies of regulation on the roller when film after, reserving film greater than 100mm length again is about to it and cuts off, with unnecessary winding film on volume film rod 2, but the film by the fixed rear portion of reeling.
In the utility model,, thereby all leave the film of certain width in the both sides of cylindrical shell, it is turned down to the center of circle along the roller edge because the length of cylindrical shell is less than the width of film.The central shaft of cylindrical shell is inserted in the baffle plate of annular, guarantees that the film after the turnover all is clipped between baffle plate 3 and the cylindrical shell 1, again clips 4 is tightened on the central shaft 11 in the cylindrical shell 1, in case baffle plate 3 is mobile.Can firmly fix film like this, prevent that it is in cross-direction shrinkage.
The utility model novel structure, with low cost, easy to use.
