The effect of straight line sliver 25 is chain 5 moving linearlies of this section.U-shaped carrier bar 27 on chain 5 is U-shaped, and the length of each carrier bar should be 2 times of chain pitch, and surface answers polishing chromium plating to process.
As shown in Figure 7, the junction surface between the U-shaped carrier bar 27 of chain 5 and adjacent U-shaped carrier bar 27 is V-arrangement or U-shaped (as label 30 places of Fig. 7).
The length L of the U-shaped carrier bar 27 of chain 5 equals 2 times of chain pitch t(L=2t), surface answers polishing chromium plating to process.
The chain 5 of film 21 top and bottom should be synchronizeed with the chain pincers on both sides in the same way operation, drive driving gear 19, driven gear drive chain wheel shaft 26 by variable frequency reducer motor, drive drive sprocket 2, chain drive-belt 5 is around regulating wheel 4, made oval-shaped circular motion by movable sprocket 3, expanding sprocket wheel 1.
Described upper expanding circle row, lower expanding circle row's rear also is provided with calibrator 22, calibrator transversely arranged setting after the large end of trapezoidal stretch section, film after the horizontal expanding that calibrator 22 records scanning is the thickness signal input multi-way control system (computer) of each row up and down, multi-way control system is exported the regulation and control instruction of each row thickness difference after treatment to the regulation and control motor 13 on the expanding circle 20 in corresponding row, regulation and control motor 13 is according to regulation and control instruction drive screw 14, nut 15, connecting plate 16, expanding sprocket wheel 1 on support arm 6 is done the motion of rising or descending, change the expanding amount of film in corresponding row, make the instruction regulation and control thickness of this row film according to thickness difference, realized that the horizontal expanding of W shape prepares microporous teflon membran and detects online each expanding amount in the ranks of branch's auto-control, reached the purpose of the uniformity of thickness being carried out to accuracy controlling.
By the circle of the expanding up and down row that each 3-20 cover expanding circle forms up and down, they minute become fan-shaped array in the trapezoidal stretch section of film 21 up and down, the expanding power that makes two general side chain pincers (left chain pincers 23, right chain pincers 24) grip the film both sides becomes the W shape and the fan-shaped expanding power of synchronizeing that each 3-20 is capable up and down, make the expanding on both sides be divided into the uniform expanding of multirow, expanding speed is synchronously carried out, and the uniformity reached in the horizontal expanding of microporous teflon membran W shape further improves.
Microporous teflon membran is that the horizontal expanding of the two-way W shape of synchronously being carried out with vertical expanding by horizontal expanding is realized.At chain 5, by the segment of trapezoidal stretch section to the stage casing of trapezoidal stretch section, be the vertical centre place of expanding sprocket wheel 1, due to upper and lower expanding sprocket wheel 1, while making the top and bottom of 5 pairs of films of chain vertically be cut into the terminal in expanding district gradually, vertical approach reaches maximum, completed 1/2 of expanding total amount, separately due to 20 one-tenth fan-shaped array of expanding circle, when chain 5 by the small end of trapezoidal stretch section during to trapezoidal stretch section middle the expanding of horizontal direction also completed the expanding amount of 1/2 total amount, the synchronous expanding amount addition of horizontal direction and vertical direction has completed the total amount of expanding.The horizontal expanding of microporous teflon membran W shape is the horizontal expanding of being realized by horizontal and vertical bi-directional synchronization expanding.
By by movable sprocket 3 between expanding sprocket wheel 1, upper lower chain 5 is in line and moves to film 21 under the control of straight line sliver 25 is vertically to increase gradually the vertical expanding of approach, simultaneously due to 20 one-tenth fan-shaped array of expanding circle, chain 5 also increases the expanding amount gradually by fan-shaped small end to fan-shaped middle section water plane, and horizontal expanding amount has completed expanding with vertical expanding amount sum at the middle part of stretch section.The expanding district (as shown in Figure 5) that this section is film, at expanding sprocket wheel 1 to this section of drive sprocket 2 because vertical approach exits and the increasing gradually of fan-shaped horizontal expanding amount gradually, 1/2 of horizontal increment is cancelled out each other with 1/2 of vertical decrement, at this section film, keep the expanding amount constant, at expanding sprocket wheel 1, to drive sprocket 2, this section film is shaping area.Therefore also comprise in the horizontal expanding of microporous teflon membran W shape and branch's device for automatically regulating that film 21 has completed expanding in 1/2 section left and right of trapezoidal stretch section, make expanding speed improve 1 times.
Because the chain 5 on expanding circle 20 is tangent with the top and bottom at film 21 two ends, expanding circle 20 is ellipse small in ends broad in the middle, the chain 5 on the expanding sprocket wheel 1 in above expanding circle row by the film 21 in the middle of the expanding district cut gradually downwards film 21 above, simultaneously, the lower plane of film 21 upwards cut the film 21 in the middle of the expanding district by chain 5 on expanding sprocket wheel 1 in lower expanding circle row, due to the relative incision of 5 pairs of film 21 top and bottom of upper lower chain, make film 21 become gradually the three-dimensional multiaspect of W shape and obtain uniform expanding by plane; Straight line sliver 25 control chains 5 are moving linearly at expanding sprocket wheel 1 and between by movable sprocket 3, moving linearly between expanding sprocket wheel 1 and drive sprocket 2.Arranging chain 5 on the oval circumference of expanding circle 20, it along expanding sprocket wheel 1, drive sprocket 2, regulating wheel 4, by movable sprocket 3, and straight line sliver 25 under the driving of drive sprocket 2, does to synchronize and move in the same way with two side chain pincers gripping films 21.The driving of drive sprocket 2 is by variable frequency reducer motor 18, drive active and passive gear 19, sprocket shaft 26, universal joint 17, make drive sprocket 2 rotarily actuate chains 5, does that oval-shaped circular motion realizes at regulating wheel 4, by movable sprocket 3, straight line sliver 25, expanding sprocket wheel 1.
The utility model device is applicable to the preparation of other plastic sheeting.
Illustrate: said apparatus only all can change for structure, connection, the kind of drive that each parts of the utility model are described; every conversion of carrying out on the basis of technical solutions of the utility model and improvement, should not get rid of outside protection domain of the present utility model.
