Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging testing technology, specifically relating to a tooling for testing the opening force of an aluminum foil easy-tear cap. Background Technology
[0002] Aluminum foil easy-tear caps are made by sealing a metal cap ring with aluminum foil or aluminum foil composite sealing film, and are easy-to-open caps. The products are available in cap diameter sizes of 300, 307, 401, 502, and 603. During use, according to standard BBT0069-2014, their bursting force and full-opening force need to be tested. The standard requires a measurement accuracy of ≤1N. The easy-tear cap is fixed in a fixture, the fixture angle is adjusted to 45°, and the other end is clamped to the handle of the sealing film. The test speed is (300±20) mm / min, and the tensile testing machine is started. The tensile force values at the moment of bursting and when fully open are recorded.
[0003] To meet this test requirement, a fixture for testing the opening force of aluminum foil easy-tear caps that is suitable for universal tensile testing machines needs to be developed. This fixture can cooperate with the upper and lower clamping mechanisms of the tensile testing machine to complete the testing of the tearing force and full opening force of the easy-tear caps.

[0006] A fixture for testing the opening force of an aluminum foil easy-tear cap includes a base plate and an inclined panel integrally formed at a 45° angle to the base plate. An aluminum channel slide rail is fixedly installed on the inclined panel, and clamps are symmetrically and slidably arranged on the aluminum channel slide rail. The clamps are fixed by bolts, and the aluminum foil easy-tear cap to be tested is clamped between the symmetrically arranged clamps.
[0007] Furthermore, the clamp includes a horizontal fixing plate, a vertical connecting plate, and a clamp head. The horizontal fixing plate is slidably installed on the aluminum channel slide rail. The vertical connecting plate connects the horizontal fixing plate and the clamp head. The easy-tear cap of the aluminum foil to be tested is clamped in the clamp slot at the front end of the clamp head.
[0008] Furthermore, a reinforcing plate is fixedly connected between the base plate and the inclined plate.
[0009] Moreover, the bolt is a wing bolt.
