A kind of diaphragm tensile test apparatus
The utility model relates to a kind of two-way or unidirectional tensile test apparatus that the thick plastic diaphragm can be stretched as diaphragm.
Along with the progressively development of domestic and international economic technology, all types of plastic thin-film sheet is applied in the every field scopes such as packing of food, cigarette, drinks, cosmetics etc.Along with twentieth century microelectric technique and high-tech development, the exploitation of each electronic product battery and power lithium-ion battery is also at home and abroad carried out in succession especially.Therefore need continually develop new high performance plastics thin-film sheet product.When developing new product often will through repeatedly or even experiment many times check composition of raw materials whether can reach the desired properties requirement.If come continuous experimental test according to traditional online test manufacture, each test manufacture all needs to drop into a large amount of raw materials, and consumes a large amount of manpower and materials etc., does not especially reach when requiring when the product of filling a prescription, and all raw materials will be wasted, and cause huge economic loss.Therefore cause the cost of product newly developed high, especially the financial burden of high-tech high-performance electronic products material is larger, so waste can allow most of producers and research and development institution hang back, and the update or the quality that have seriously restricted product improve, thereby have weakened the market competitiveness.

A kind of diaphragm tensile test apparatus, it comprises for the diaphragm tensile part 1 of clamping and stretching film and is used for diaphragm tensile part clamping diaphragm is heated and cooling wind circulating device.
As shown in Figure 1, the wind circulating device comprises air-intaking box 2, the first electrical heating baking oven 3, hot air circulation blower fan 7, bellows 8, the second electrical heating baking oven 9 and cold wind circulation air machine 10.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 hot air circulation blower fan 7 by 90 ° of air channels 4, hot air circulation connects by bellows 8 below that the second electrical heating baking oven 9, the second electrical heating baking ovens 9 are arranged on the diaphragm tensile part 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 and hot air circulation share air-intaking box 2,90 ° of air channels 4 and bellows 8 with blower fan 7.
The diaphragm tensile part is the core component in the diaphragm tensile test apparatus, and as shown in Figure 2, it comprises four parallel in twos guide rails 11, and every two closed slides form one group, and two groups of guide rails are orthogonal.Be equipped with array slide block 12 on every guide rail, geometrical clamp film fixture 13 on slide block 12, folder film fixture 13 is used for the clamping diaphragm.Every group of guide rail controlled separately by a drive unit respectively.In the time of need to stretching to diaphragm, first adopt folder film fixture 13 that diaphragm is clamped, then control guide rail by drive unit, and drive folder film fixture 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 that synchronous bidirectional different multiples draw ratio stretches, unidirectional different multiples draw ratio stretches.
Folder film fixture is the key in the diaphragm tensile part, and as shown in Figure 3, it comprises folder film lower jaw 14 and folder film maxilla 15, clamping diaphragm between folder film lower jaw 14 and folder film maxilla 15.Be provided with fixed block 19 on folder film maxilla 15, fixed block 19 is controlled by cylinder 20, and cylinder 20 is laterally placed, and takes up space little.When needing to place 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 and lift, press from both sides the state that film maxilla 15 and folder film lower jaw 14 are in unlatching this moment, can place diaphragm.After diaphragm places, the pressurized air that breaks, the cylinder rod automatic retracted, folder film maxilla 15 falls, until with folder film lower jaw 14 closures, clamp by the machine automatization formula this moment.
The below describes the course of work of the present utility model:
The thick film sheet is cut to square or rectangle is clamped on film fixture 13 according to the technique needs, opens the heating element in the first electrical heating baking oven 3 and the second electrical heating baking oven 9, open simultaneously motor 6 and drive hot air circulation with blower fans 7 work by V-type band 5.To diaphragm heat up be preheating to moderate temperature after, close the heating element in the first electrical heating baking oven 3, waiting heats up arrive require after, open one or two unidirectional or bi-directional synchronization of completing diaphragm of drive unit switch and stretch.After diaphragm is stretched to required draw ratio, then the second electrical heating baking oven 9 is closed, and keep standing state a period of time, lean on the diaphragm thermal finalization after present temperature is completed the diaphragm stretching.After thermal finalization is completed, open cool cycles wind with blower fan 10, carry out the cold wind circulation, stop the cold wind circulation after diaphragm is cooled to design temperature, open folder film fixture 13 and take out diaphragm, complete plastic film tension test process.
The utility model diaphragm tensile test apparatus can be completed the Uniform Tension test of multiple plastic film.And can require accurately to complete according to different process unidirectional, the bi-directional synchronization stretched operation of different multiples.And the diaphragm tensile part can realize heating, typing, cooling three kinds of operations simultaneously at same station, and easy switching between three kinds of operations.
Need to prove, under the instruction of this instructions, any equivalents that those skilled in the art have done, or obvious variant all should be within protection domains of the present utility model.
