Description

Technical Field

[0001] The invention relates to the technical field of cultural relics detection, in particular to a paint detection device for cultural relics restoration. Background Art

[0002] In order to protect and restore cultural relics and allow historical relics to show their original style and appearance, our country has now launched cultural relic repair projects in various regions. The damaged parts of cultural relics are repaired without changing the original structure and shape to achieve the purpose of protection and inheritance. For many wooden cultural relics, during the repair process, the damaged parts of the cultural relics need to be repaired, and then repainted according to their original colors to restore their original appearance. However, cultural relics are very precious and cannot be replicated. When repainting, if the paint is too thin or too thick, it can cause sagging. If it is applied too thickly, it will also cause sagging. Therefore, the viscosity and color of the paint need to be tested before use to avoid using unsuitable paint, which will cause irreversible damage to the cultural relics:

[0003] Under the prior art, a Chinese patent with the publication number "CN111638157A" discloses a paint detection device for cultural relics repair projects, which relates to the field of cultural relics repair. In the paint detection device for cultural relics repair projects, a fixed shaft is connected to the side of the column, a rotating seat is rotatably connected to the outer surface of the fixed shaft, a gear is fixedly connected to the side of the rotating seat, a splint is movably clamped on the upper surface of the rotating seat, a fixed rod is connected to the side of the column, a clamping assembly is provided inside the fixed rod, and the end of the clamping assembly is movably clamped with the gear, the wooden strip is clamped between the two groups of splints, and then the paint is applied to the upper surface of the wooden strip, the six groups of rotating seats are adjusted, and the gears are clamped and fixed by triangular clamping blocks, so that the angle between the two adjacent groups increases by 30 degrees, so that the six groups of wooden strips are tested for paint hanging at different angles, so as to judge the viscosity of the paint, and check it at intervals;

[0004] The above patent can restore cultural relics as non-destructively as possible by detecting the drying speed of the paint and the state after drying. However, in actual operation, after the paint is applied, multiple fixing groups need to be rotated to fix the wooden strips, and at the same time, the staggered angle of each adjacent fixing group needs to be controlled to be 30 degrees. It is extremely cumbersome to use and it is easy for the staff to be contaminated by the paint.
