Press cutting sample preparation rolling wheel for waterproof coiled materials and sample preparation device

Abstract

The invention provides a press cutting sample preparation rolling wheel for waterproof coiled materials and a sample preparation device. The press cutting sample preparation rolling wheel comprises apress cutting rolling wheel (11) and a center shaft (1) movably connected with the press cutting rolling wheel (11), the periphery of the press cutting rolling wheel (11) is divided into a blank area(3) and a cutter area (2), the cutter area (2) is provided with a plurality of cutters protruding out of the external surface of a blade layer, and elastic parts are arranged in the cutters. The presscutting sample preparation device further comprises a matching cutting device. The cutting device fixes the multiple specially-made cutters on the press cutting rolling wheel (11), then the press cutting rolling wheel (11) is connected with the matching cutting device, and through the rotation of the press cutting rolling wheel, the waterproof coiled materials pass under the rolling wheel and arepressed and cut into to-be-detected samples by the multiple cutters with different shapes. A variety of the samples to be detected can be cut out by the press cutting rolling wheel at a time, the cut-out samples can automatically pop up the cutters, the cutting efficiency is high, in addition, the longitudinal and transverse directions of the cut-out samples can be marked, and the samples are noteasily confused during detection.

Description

technical field [0001] The invention relates to an auxiliary tool for engineering testing and detection, in particular to a press-cut sample preparation roller and a press-cut sample preparation device for waterproof coiled materials. Background technique [0002] The waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of rolls and are called waterproof rolls. Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. [0003] According to national standards, it is necessary to perform performance testing and testing tests on waterproof membranes, such as sample prepar...

AI Technical Summary

Problems solved by technology

Even if the same size test strip is divided into vertical and horizontal relative to the original coil, sometimes a longitudinal sample is required, and sometimes a horizontal sample is required. It is easy to confuse the sample preparation, and the waterproof membrane has good flexibility. , it is difficult to maintain a consistent size for each cut, which also affects the accuracy of coil testing results

[0004] In the prior art, patent 201520419221.2 discloses a waterproof coil sample making machine, patent 201420783993.X discloses a waterproof coil hydraulic sample maker, and patent 2018205096061 discloses a waterproof coil sample preparation device. The above devices realize The waterproof membrane is cut, but only one sample can be cut at a time. It is difficult to ensure a consistent size for each cut, and there is no marking of the longitudinal and transverse directions of the membrane, which is easy to confuse
