Description
Technical field
The utility model relates to a kind of polyethylene foam equipment, especially relates to a kind of electron irradiation crosslinked polyethylene foaming machine.
Background technology
Electron irradiation crosslinked polyethylene foaming machine generally comprises pay-off, foam device, positive and negative calendering device and the wrap-up that is provided with in order; Its course of work is: at first through pay-off the polyethylene raw material is transported in the foam device; The polyethylene raw material carries out obtaining the output of IXPE foam sheet semi-finished product behind the electron irradiation crosslinked foaming in foam device; And then through the positive and negative calendering device IXPE foam sheet semi-finished product are carried out obtaining IXPE foam sheet finished product after the press polish, at last through wrap-up with the rolling of IXPE foam sheet finished product.Foam device in the electron irradiation crosslinked polyethylene foaming machine mainly comprises horizontal preheating mechanism and vertical foaming stove; Because IXPE foam sheet semi-finished product temperature is higher; Lighter weight; The edge shrinks easily or is folding, mainly through expander is set in the vertical foaming stove the half-finished edge of IXPE foam sheet is adjusted at present, guarantees that its width is even.Expander generally comprises two expanding unit, the body of heater both sides that are fixed on the vertical foaming stove of two expanding unit symmetries, but the central shaft of existing expanding unit is connected through bearing with base plate; Gear frame is fixedly connected with central shaft, so that in the expanding process, gear frame drives central shaft and swings together; Whole amplitude of fluctuation is bigger, and stability of equilibrium is not high, and the expanding effect is general; Because base plate is fixed on the body of heater of vertical foaming stove, and temperature is higher, generally reach more than 250 degree in addition; So that the bearing that is connected between central shaft and the base plate is necessary for high-temperature bearing, and cost is higher.
Summary of the invention
It is strong that the utility model technical problem to be solved provides a kind of expander stability of equilibrium, the electron irradiation crosslinked polyethylene foaming machine that expanding is effective.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of electron irradiation crosslinked polyethylene foaming machine; Comprise the pay-off, foam device, positive and negative calendering device and the wrap-up that are provided with in order; Described foam device comprises horizontal preheating mechanism and vertical foaming stove; Be provided with expander in the described vertical foaming stove; Described expander comprises two expanding unit; Two both sides that are fixedly set in described vertical foaming stove that described expanding unit is symmetrical respectively, described expanding unit comprises base plate, central shaft, first driving mechanism, second driving mechanism, the first expanding pipe, second expanding pipe and the gear frame, described base plate is fixedly mounted on the body of heater of described vertical foaming stove; One end of described central shaft is fixedly mounted on the described base plate; The other end of described central shaft successively is connected through two bearings with described gear frame, and described first expanding pipe and the described second expanding pipe and described gear frame are coupling, and described first expanding pipe and the described second expanding pipe laterally arrange; Described first driving mechanism is connected with described gear frame, and described second driving mechanism is connected with the described second expanding pipe with the described first expanding pipe respectively.
Two described bearings are plain bearing.
The described first expanding pipe has than the big length of the described second expanding pipe.
Described first driving mechanism and described second driving mechanism are motor.
Be coated with adherent layer on the surface of described first expanding pipe and the described second expanding pipe.
Described adherent layer is a nano coating, and the thickness of described nano coating is 35 μ m.
Compared with prior art; The advantage of the utility model is in the expanding unit central shaft to be fixedly mounted on the base plate, and central shaft is connected through two bearings with gear frame, and gear frame integral body is swung around central shaft; Central shaft is static; Expanding whole unit amplitude of fluctuation is less, has strengthened the stability of equilibrium of expander, and expanding is effective;
When central shaft was connected through two plain bearings with gear frame, because gear frame does not contact with the body of heater of vertical foaming stove, its temperature was lower, and plain bearing can bear the temperature here, can practice thrift cost.
When the surface of the first expanding pipe and the second expanding pipe is coated with adherent layer; Volatile matter adheres on the first expanding pipe and the second expanding pipe in the time of can preventing the blowing agent foaming on the one hand, has also avoided the frequent clean to the first expanding pipe and the second expanding pipe on the other hand;
When adherent layer is a nano coating, and thickness can guarantee that adherent layer does not firmly come off when being 35 μ m, and reliability is high.
