Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 5, the present embodiment provides a non-woven fabric tester, which includes a testing arm 1, a base 2, a pressure spring 3, a controller 4, an LED lamp 5, a first illumination intensity sensor 6, a second illumination intensity sensor 7, and a tact switch 8.

The rear end of the test arm 1 is hinged to the rear end of the base 2 (the hinge technology is conventional in the art and will not be described in detail here). One end of the pressure spring 3 is connected to the middle part of the test arm 1, and the other end of the pressure spring 3 is connected to the middle part of the base 2; when the pressure spring 3 is free from external force, the pressure spring 3 supports the front end part of the test arm 1 to be separated from the front end part of the base 2, as shown in fig. 1.

The front end of the base 21 is provided with a first groove 20, and the first illumination intensity sensor 6 is arranged in the first groove 20. The front end of the testing arm 1 is provided with a second groove 10, and when the front end of the testing arm 1 is pressed against the front end of the base 2 by the pressure spring 3 under the action of external force, the second groove 10 corresponds to the first groove 20, as shown in fig. 2 and 3. LED lamp 5 and second illumination intensity sensor 7 set up in second recess 10, and it should be noted that, should not shelter from LED lamp 5 and shine and wait to detect non-woven fabrics 100 when second illumination intensity sensor 7 installs.

The controller 4 comprises a shell 40 arranged on the test arm 1, a display screen 41 and a switch key 42 are arranged on the surface of the shell 40, and a processor 43, a lithium battery 44 and an LED drive circuit module 45 are arranged in the shell 40. In this embodiment, preferably, the processor is an AT89C51 series single chip microcomputer. All the electronic components and the circuit module are existing equipment.
