Embodiment 1

[0038] Such as figure 2 As shown in the measurement schematic diagram, the present embodiment continuously measures the transverse tensile strength of the reel material with the following steps:

[0039] S1. Set the reel material fixing device 1 and the reel material collecting device 3, the said fixing device 1 continuously conveys the reel material to the collecting device 3 through the rotation of its shaft, and the collecting device 3 collects the reel material by rotating to ensure that both The reel material 5 between is horizontal state;

[0040] S2. A tensile strength measuring device 4 is arranged between the reel material fixing device 1 and the reel material collecting device 3;

[0041] S3. Use the tensile strength measuring device 4 to measure the transverse tensile strength of the reel material between the fixing device 1 and the collecting device 3, collect the measured reel material by rotation, and select the next measuring point at the same time.

Embodiment 2

[0043] In this embodiment, a detection device is designed according to the detection method of the present invention as attached image 3 shown. attached figure 2 Among them, 1 is the reel material fixing unit, 2 is the material changing component, 3 is the material collecting component, and 4 is the tensile strength tester.

[0044]The material collection assembly 3 rotates and collects the measured material in an electric manner, and at the same time selects the next measuring point. When the stop button is pressed, the collection assembly stops rotating, which can realize random stop collection of materials.

[0045] The detection steps of the present invention are as follows:

[0046] Select the shaft whose diameter matches the core diameter of the reel material to be tested, load the material to be tested into the reel material fixing unit, adjust the clamp on the shaft, and fix the reel material on the shaft;

[0047] Select a shaft whose diameter matches the core d...

Embodiment 3

[0052] The difference from Example 2 is that the material collection assembly adopts an electric method that can set a fixed distance to stop collection, and can automatically realize the fixed distance between measurement points. After measuring the tensile strength of the first point, the measured material can be rotated and collected by electric means, and at the same time stop selecting the next measuring point after a fixed distance (such as 20 cm).

Abstract

The invention discloses a method for continuously measuring the transverse tensile strength of a reel material and application of the method. The method comprises the following steps: arranging a reel material fixing device and a reel material collection device, wherein the fixing device continuously conveys the reel material to the collection device through shaft rotation, the collection device collects the reel material through rotation, and the reel material between the fixing device and the collection device can be kept in a horizontal state; arranging a tensile strength measurement device between the reel material fixing device and the reel material collection device; and performing transverse tensile strength measurement on the reel material between the fixing device and the collection device through the tensile strength measurement device, performing rotary collection on the measured reel material, and selecting a next measurement point. The method disclosed by the invention is simple in method and easy to operate; the transverse tensile strength of the reel material can be continuously efficiently and flexibly measured; the method can be well applied to development judgment on the uniformity of the reel material or can pre-judge the on-machine adaptability of the material before the material is tested on a machine.

Description

technical field [0001] The invention relates to the technical field of testing the transverse tensile strength of reel materials, and more particularly, relates to a continuous measurement method and application of the transverse tensile strength of reel materials. Background technique [0002] Transverse tensile strength is one of the indicators that must be considered in the design of reel materials, and it is also the main factor affecting the material's performance in production and application. The transverse tensile strength test methods mainly include constant-speed loading method and constant-speed tensile method. Both methods use a tensile strength tester, and the characterization indicators include tensile strength, tensile index, elongation at break, tensile energy absorption, tensile energy absorption index, and elastic modulus. The specific operation method is to cut the sample to the specified size, and clamp the cut sample between the two chucks of the tensil...
