Detection device for detecting hardness of color steel paint film

Abstract

The invention discloses a detection device for detecting the hardness of a color steel paint film, the detection device comprises a base, a bottom plate, a first driving mechanism, a placement table, a support frame and a pencil holder, the bottom plate is movably arranged on the base, the first driving mechanism is arranged on the base and comprises a motor and a screw rod, the motor is arranged on the base, and an output shaft of the motor is in transmission connection with the screw rod; the bottom of the bottom plate is mounted on the screw, the placement table is movably arranged on the bottom plate, the supporting frame is arranged on the base, one end of the supporting frame extends to the position above the placement table, the pencil holder comprises a mounting block and a pencil, one end of the mounting block is mounted at the end, extending to the placement table, of the supporting frame, and an inclined plane is formed at the tail end of the other end of the mounting block. A through hole penetrating to the bottom of the mounting block is formed in the slope, one end of the pencil penetrates through the through hole to abut against the color steel of the containing table, the motor drives the screw to drive the bottom plate to reciprocate, and the pencil slides on the surface of the color steel for scribing. The color steel is uniformly scraped and slipped through the pencil, and the paint film hardness detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of film layer hardness detection equipment, in particular to a detection device for detecting the hardness of a color steel paint film. Background technique [0002] Film hardness testing equipment is an indispensable test equipment in plastic spraying, metal electroplating and other industries. The hardness of the film is measured by scratching the film with a pencil marked with a hardness level. It is a special tool for measuring the hardness index of the film. tool. In the color steel production industry, it is often necessary to test the hardness of the paint film on the surface of the color steel through film hardness testing equipment, and the existing film hardness testing equipment is generally directly pushed by hand, and then according to the pencil on the color steel Slip marks on the steel surface to determine the hardness of the paint film of the color steel. Due to the manual operation, different teste...

AI Technical Summary

Problems solved by technology

Due to the manual operation, different testers push differently, which leads to inconsistent results of paint film hardness measurement, and it is difficult to judge the real paint film hardness of color steel.
