Description

Bottle cap torque testing device applied to bottle body package Technical Field The invention belongs to the technical field of torque testing, and particularly relates to a bottle cap torque testing device applied to bottle body packaging. Background In the process of filling and packaging production, the torque of the bottle cap is a key index influencing the tightness of packaging, the transportation safety and the user opening experience, so that the torque test of the bottle cap is one of the core links of product delivery inspection. In order to ensure the test precision, the filling packaging bottle needs to be stably positioned in the test process, so that the phenomenon that the bottle body is displaced or rocked when the bottle cap is twisted to cause torque signal transmission distortion and influence the reliability of the test result is avoided. At present, the bottle body positioning mode of the existing bottle cap torque testing device mainly comprises bottom clamping, namely clamping and fixing are carried out on the bottom of the bottle body through a clamp, so that basic positioning is achieved. The positioning structure is simple in design, and can barely meet basic test requirements when being used for packaging a short bottle body and a filling body with a low gravity center. However, in actual production, for the packaging of bottles such as fruit juice, edible oil, daily chemicals, etc., the design height of the bottle body is often high to improve the capacity and the appearance practicality, and the limitation of the existing bottom clamping mode is more remarkable. Because only the bottom of the bottle body is clamped, the middle and upper parts of the high bottle body lack effective restraint and support, and the overall rigidity is not enough. In the torque test process, when a torsion force is applied to the bottle cap, the middle and upper parts of the bottle body are easy to deflect, shake and even twist due to stress, and the whole static state cannot be maintained. The displacement not only can lead to deviation of signals collected by the torque tester, so that test data are inaccurate, but also can cause damage such as side wall scratch and deformation of the bottle body and influence product quality due to uneven local stress caused by shaking of the bottle body. The present invention has been made in view of this.
