Universal testing machine capable of measuring cutting force

Abstract

The invention relates to the field of frozen meat cutting equipment, in particular to a universal testing machine capable of measuring cutting force. The universal testing machine capable of measuring cutting force comprises an operating main body, an upper clamp body and a lower clamp body, wherein the upper clamp body and the lower clamp body are arranged corresponding to each other up and down and are both mounted on the operating main body. A cutter is mounted at the lower end of the upper clamp body, and a downward pressing disk used for storing a cut object is mounted at the upper end of the lower clamp body. An adjusting device used for controlling the upper clamp body to move up and down and a force sensor are arranged inside the operating main body, the output end of the force sensor is connected with a controller, and the controller can obtain the force which is applied by the cutter in the sample cutting process according to output signals of the force sensor. By the adoption of the universal testing machine, the size variation of cutting force of the cutter acting within certain displacement can be accurately reflected, the quantization of frozen meat cutting force can be achieved, and thus a refrigeration and preservation technology of a refrigerator can be better evaluated; moreover, the cutter can be effectively fixed, a cut sample can be well fixed, and therefore test errors are reduced to be minimum.

Description

technical field [0001] The invention relates to the field of frozen meat cutting equipment, in particular to a universal testing machine capable of measuring cutting force. Background technique [0002] In the prior art, there are various technologies for freezing and keeping fresh in refrigerators, and almost all refrigerators have the function of keeping fresh and freezing. Therefore, it is a common phenomenon to put food into the refrigerator for freezing. However, the frozen food taken out from the refrigerator freezer, especially meat food, generally has the problem of being difficult to cut, and the degree of difficulty of cutting is only judged by subjective feeling, and the degree of difficulty of cutting cannot be quantified . [0003] If the degree of difficulty of cutting the frozen food can be quantified, the freezing effect of the refrigerator can be judged according to the quantified value, and then the freezing effect of the refrigerator can be improved so th...

Problems solved by technology

However, there is no device in the prior art that can quantify the ease of cutting frozen food taken out of the refrigerator freezer

Therefore, in the prior art, it is not possible to evaluate the freezing and fresh-keeping technology of the refrigerator according to the degree of difficulty of cutting the frozen food.

[0004] In view of the above problems, there is an urgent need for a universal testing machine that can measure the cutting force, so as to solve the problem that the frozen meat cutting force cannot be quantified in the prior art.
