Problems solved by technology

[0002] The Shore hardness tester is widely used in the hardness measurement of rubber and plastics. It has the characteristics of simple structure, convenient use, light weight, and intuitive reading. When the surface of the presser foot is fully attached to the surface of the sample, the tip surface of the indenter has a certain extension length relative to the plane of the presser foot, and the smallness of the elongation is used to characterize the Shore hardness. The protruding indenter is easily worn during use, which greatly shortens the service life of the hardness tester; and the existing Shore hardness tester has a simple structure and a single function, which has caused problems for the use and promotion of the Shore hardness tester. certain restrictions

Embodiment 1

[0012] The invention includes a detection body 1, a base 2, a side arm 3, a pressure needle installation block 4, a sensor 5, a pressure needle 6, a measuring platform 7, a lifting slider 8, a scale 9, an inner cylinder 10, a pressure foot 11, a protection When installing the outer cylinder 12 and the indicator strip 13, the scale 9 is first installed on the side arm 3, the side arm 3 is installed on the upper end of the base 2, the measuring platform 7 is installed on the upper end of the base 2, and then the detection body 1 Install the inner cylinder 10 inside, set the presser foot 11 at the lower end of the installation inner cylinder 10, then install the pressure needle 6 on the lower end of the pressure needle installation block 4 through the sensor 5, and install the pressure needle installation block 4 on the installation inner cylinder 10 Then install the indicator strip 13 on the lower end of the protection outer cylinder 12, install the protection outer cylinder 12 o...

Embodiment 2

[0014] When in use, first put the test sample on the measuring table 7, adjust the lifting slider 8 downwards, so that the lower end of the protection outer cylinder 12 contacts the test sample, at this time the indicator strip 13 and the scale 9 represent the test sample Continue to adjust the lifting slider 8 downwards, so that the protection outer cylinder 12 moves upward relative to the installation inner cylinder 10. At this time, the pressure needle 6 presses into the test sample, and when the press foot 11 is in full contact with the test sample, it passes through the sensor. 5 Detect the Shore hardness of the test sample.

Abstract

The invention provides a multifunctional shore durometer for detecting the plastic hardness. The shore durometer comprises a detection body, a base, a side arm, a press needle installing block, a sensor and the like, wherein a measuring table is arranged at the upper end of the base, the side arm is installed at the upper end of the base, a graduation ruler is arranged on the side arm, a lifting slide block is installed on the side arm, a detection body is installed at the lower end of the lifting slide block, an installing inner cylinder is arranged inside the detection body, a press foot is arranged at the lower end of the installing inner cylinder, the press needle installing block is installed inside the installing inner cylinder, and a press needle is installed at the lower end of the press needle installing block through a sensor. The detection body is configured to include the installing inner cylinder and a protecting outer cylinder which can move relatively, the protecting outer cylinder can protect the press needle, bump and abrasion suffered by the press needle in the using process are greatly decreased, and accordingly the service life of the shore durometer is prolonged.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for the production of plastic particles, in particular to a Shore durometer used to detect the hardness of plastics. Background technique [0002] The Shore hardness tester is widely used in the hardness measurement of rubber and plastics. It has the characteristics of simple structure, convenient use, light weight, and intuitive reading. When the surface of the presser foot is fully attached to the surface of the sample, the tip surface of the indenter has a certain extension length relative to the plane of the presser foot, and the degree of elongation is used to characterize the Shore hardness. The protruding indenter is easily worn during use, which greatly shortens the service life of the hardness tester; and the existing Shore hardness tester has a simple structure and a single function, which has caused problems for the use and promotion of the Shore hardness tester. Certain restrictions...
