Embodiment
A kind of expansion diaphragm stretching device, it comprises for clamping and the diaphragm tensile part 1 of stretching film and for diaphragm tensile part clamping diaphragm is heated and cooling gas phase loop structure.
As shown in Figure 1, gas phase loop structure comprises air-intaking box 2, the first electrical heating baking oven 3, blower fan 7, bellows 8, the second electrical heating baking oven 9 and cold wind circulation air machine 10 for hot air circulation.Air-intaking box 2 is arranged on the top of diaphragm tensile part, it is connected with the first electrical heating baking oven 3, the first electrical heating baking oven 3 connects blower fan 7 for hot air circulation by 90 ° of air channels 4, hot air circulation is connected the second electrical heating baking oven 9, the second electrical heating baking ovens 9 and is arranged on the below of diaphragm tensile part by bellows 8 with blower fan 7.Hot air circulation drives running by V-type band 5 by motor 6 with blower fan 7.Cold wind circulation air machine 10 shares 2,90 ° of air channels of air-intaking box 4 and bellows 8 with hot air circulation with blower fan 7.
Diaphragm tensile part is the core component in expansion diaphragm stretching device, and as shown in Figure 2, it comprises four parallel between two guide rails 11, and every two closed slides form one group, and two groups of guide rails are orthogonal.On every guide rail, be equipped with array slide block 12, geometrical clamp membrane structure 13 on slide block 12, folder membrane structure 13 is for clamping diaphragm.Every group of guide rail controlled separately by a drive unit respectively.Need to stretch to diaphragm time, first adopt folder membrane structure 13 that diaphragm is clamped, then by drive unit control guide rail, and drive folder membrane structure by array slide block on guide rail, and then diaphragm is stretched.Because every group of guide rail controlled separately by a drive unit respectively, thereby can realize the stretching of synchronous bidirectional different multiples draw ratio, the stretching of unidirectional different multiples draw ratio.
Folder membrane structure is the key in diaphragm tensile part, and as shown in Figure 3, it comprises folder film lower jaw 14 and folder film maxilla 15, between folder film lower jaw 14 and folder film maxilla 15, clamps diaphragm.On folder film maxilla 15, be provided with fixed block 19, fixed block 19 is controlled by cylinder 20, and cylinder 20 is laterally placed, and takes up space little.When need to placing diaphragm or taking out diaphragm, the logical pressurized air of tracheae that cylinder 20 is connected by joint 21, cylinder rod stretches out, promoting fixed block 19 moves, and then drive folder film maxilla 15 to lift, and now press from both sides film maxilla 15 and the state of folder film lower jaw 14 in opening, can place diaphragm.After diaphragm places, the pressurized air that breaks, cylinder rod automatic retracted, folder film maxilla 15 falls, until with folder film lower jaw 14 closures, now clamp by machine automatization formula.
Below the course of work of the present invention is described:
Thick film sheet need to be cut to square or rectangle according to technique and be clamped in membrane structure 13, open the heating element in the first electrical heating baking oven 3 and the second electrical heating baking oven 9, open motor 6 simultaneously and drive hot air circulation blower fan 7 to work by V-type band 5.Diaphragm is heated up and is preheating to after moderate temperature, close the heating element in the first electrical heating baking oven 3, waiting heats up arrives after requirement, opens one or two unidirectional or bi-directional synchronization that complete diaphragm of drive unit switch and stretches.Diaphragm is stretched to after required draw ratio, then the second electrical heating baking oven 9 is closed, and keeps standing state a period of time, completes the diaphragm thermal finalization after diaphragm stretches by current temperature.After thermal finalization completes, open blower fan 10 for cool cycles wind, carry out cold wind circulation, after diaphragm is cooled to design temperature, stop cold wind circulation, open folder membrane structure 13 and take out diaphragm, complete plastic film tension test process.
Expansion diaphragm stretching device of the present invention, can complete the Uniform Tension test of multiple plastic film.And can require accurately complete unidirectional, the bi-directional synchronization stretched operation of different multiples according to different process.And diaphragm tensile part can realize heating, sizing, cooling three kinds of operations at same station simultaneously, and easy switching between three kinds of operations.
It should be noted that, under the instruction of this instructions, any equivalents that those skilled in the art have done, or obvious variant, all should be within protection scope of the present invention.
