The device for testing the performance of the adhesive tape 1 shown in fig. 2 is suitable for testing by using a universal testing machine, the universal testing machine is also called a tensile machine in the field of testing the adhesive tape 1, and further comprises a first testing piece 2 and a second testing piece 3, and the first testing piece 2 and the second testing piece 3 are connected into a whole by the contact surfaces of the first testing piece 2 and the second testing piece 3 through the adhesive tape 1 to form a testing piece. Preferably, the first test piece 2 and the second test piece 3 are the same in structure and are symmetrically arranged, and the purpose is to enable the stress to be uniform and equal, namely, the tensile force applied to the two faces of the adhesive tape 1 is uniform and equal, and the test accuracy is improved. Preferably, the first test piece 2 and the second test piece 3 are T-shaped structures, and one end of a T-shaped head connects the first test piece 2 and the second test piece 3 through the adhesive tape 1.
During the test, the both ends of testing the piece in vertical direction are connected with universal tester respectively, and universal tester stretches first test piece 2 and second test piece 3 to accomplish the capability test of sticky tape 1.
The tensile machine of current product includes grip block 4 and actuating mechanism, and actuating mechanism is hydraulic system and can drive grip block 4 and remove along vertical direction.
For avoid first test piece 2 and second test and tensile machine to produce the displacement because of the rigidity mounting means, for example, the tensile machine includes the rigidity centre gripping of grip block 4 and test piece, when actuating mechanism drives grip block 4 and removes, can produce certain displacement or the uneven phenomenon of atress with the test piece and cause whole test result bigger than normal, the performance data of reaction sticky tape 1 that can not be accurate, consequently, first test piece 2 and second test are keeping away from the one end of mutual contact face and the symmetry is provided with first through-hole 21 and second through-hole 31, universal testing machine acts on first through-hole 21 and second through-hole 31 and stretches first test piece 2 and second test piece 3 respectively. Preferably, the first through hole 21 and the second through hole 31 are respectively arranged near one end of the first test piece 2 and one end of the second test piece far away from the adhesive tape 1, so as to facilitate the installation with a tensile machine.
In the traditional mode, the test piece is rigidly connected with the clamping plate, so that the test piece moves during testing, or the clamping plate damages the integrity of the test piece, so that the performance data of the adhesive tape is smaller or lower.
For example, the universal tester comprises an upper driving mechanism 51, a lower driving mechanism 52, a first iron chain and a second iron chain, or two S-shaped hooks with the same structure, wherein:
the first iron chain passes through the first through hole 21 to be connected with the upper driving mechanism 51, and the second iron chain passes through the second through hole 31 to be connected with the lower driving mechanism 52; the upper and lower driving structures act on acting forces of the first iron chain and the second iron chain in different directions in the vertical direction, and the first test piece 2 and the second test piece 3 are stretched to complete the performance test of the adhesive tape 1;
