Description
Technical Field
The utility model relates to a thermal contraction membrane strength test device belongs to mechanics check out test set technical field.
Background
After the heat shrinkable film is formed, a series of property tests are required, and among them, the test of tensile strength is an important item. In the existing industry, a sample is firstly prepared, and two ends of the sample are fixed by adopting a special component. The fixing is usually performed by pressing, but the pressing crushes the sample of the heat shrinkable film, the thickness is reduced, and the thickness of the sample changes at the edge of the clamping part. During the process of stretching the sample, the clamped edge is easy to be broken first, so that the stretching experiment data is not objective and accurate.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve exist among the prior art not enough, provide one kind and need not to compress tightly the heat shrink film strength test device that the sample can carry out tensile detection, be favorable to guaranteeing objectivity and the accuracy of tensile sample data.
The utility model discloses a realize through following technical scheme:
the utility model provides a thermal contraction membrane strength test device, the on-line screen storage device comprises a base, the fixed mount that is equipped with on the left end of base, the guide rail has been seted up to the base upper end, install on the guide rail and remove the frame, the bottom that removes the frame is equipped with the slider, the slider is located the guide rail, remove and still seted up a screw hole on the frame, respectively be equipped with two double-screw bolts on mount and the removal frame, the cover has two on per two double-screw bolts and pastes the board, both ends paste in two pairs paste the board about the sample, it is fixed through glue paste between the board, it is fixed through the nut on the double-screw bolt to paste the board cover, it is equipped with the lead screw to pass the screw hole, both ends support through two bearing frames.
The utility model discloses need not to compress tightly the sample and can carry out tensile detection, guarantee the homogeneity of whole thermal contraction membrane sample thickness, objective more, the accuracy of data that obtain at tensile in-process.
Further preferably, the adhesive plate can be a wood plate or a plastic plate.
Compared with the prior art, the utility model discloses the beneficial effect who has is:
the utility model discloses need not to compress tightly the sample and can carry out tensile detection, guarantee the homogeneity of whole thermal contraction membrane sample thickness, objective more, the accuracy of data that obtain at tensile in-process.
