The right door panel is driven by a cylinder to open and close, and the rear wall panel is driven by a driving mechanism to make horizontal linear motion forward and backward. The rod-shaped materials are stacked in a space formed by the wall panels and the right door panel in a closed state in a direction perpendicular to the front wall panel. The driving mechanism is adjusted to drive the front wall panel to move horizontally forward and backward along the length direction of the rod-shaped materials so that the distance between the rear wall panel and the front wall panel is slightly larger than the length of the rod-shaped materials. The air circuit is connected to start the cylinder to open the right door panel connected thereto, so that the stacked rod-shaped materials in the original static state are instantly dumped onto the bottom plate.

The present invention can quickly and conveniently realize the natural stacking of rod-shaped materials and form a stacking angle, and the stacking angle obtained by measurement can improve the accuracy of simulation analysis of the motion characteristics of rod-shaped materials.

Description

Technical Field

[0001] The invention relates to an automated detection technology, and in particular to a device and method for testing the collapse of a side wall of a piled corner of a rod-shaped material. Background Art

[0002] The slope of the pile when the material is naturally piled up (i.e. the angle between the pile and the ground) is called the accumulation angle, also known as the angle of repose or the angle of rest. The accumulation angle is related to the density, surface area, shape and friction coefficient of the material. The measured material accumulation angle data can be used for the simulation of material motion characteristics in discrete element analysis software.

[0003] Most of the current material accumulation angle test methods and test equipment are only suitable for the measurement of the accumulation angle of granular materials.

[0004] For the stacking angle of rod-shaped or strip-shaped materials such as cigarettes, filter rods, straw, etc., the "side wall collapse" method is usually used. The side wall collapse is to pile the materials against the walls on all four sides in a certain direction, then pull out the wall on one side, let the materials collapse through this outlet, and then measure the slope formed with the ground. The determination of the stacking angle of a rod-shaped material requires a certain amount of materials to be tested repeatedly, and then the required data is obtained through orthogonal test design and other methods. However, the existing side wall collapse test device for the stacking angle of rod-shaped materials is relatively simple, with a low degree of automation, too much manual intervention, time-consuming and labor-intensive, and because of manual intervention, the accuracy of the results will be more or less affected. For example, when pulling out one side of the wall manually, the speed, angle, and strength will be different each time, resulting in the state of the material being different each time when it collapses, which will affect the accuracy of the final stacking angle. At the same time, the existing rod-shaped material stacking corner side wall collapse test device can only test materials of a single length specification and cannot be adjusted when the material length changes. When changing the material for measurement, the test device parts need to be customized and assembled again, which is costly and time-consuming. Summary of the invention
