Description

Technical Field

[0001] The utility model relates to the technical field of tinplate detection, in particular to a convenient visual tinplate brightness detector. Background Art

[0002] Tinplate typically refers to a thin, 0.12-0.6mm thick, cold-rolled sheet metal electroplated with tin. It is widely used in food, beverage, and premium cans. For premium can applications, surface gloss is a crucial evaluation metric, as varying tinplate gloss affects the metallic luster of the final product, resulting in varying appearances. Furthermore, while gloss is primarily influenced by the thickness of the tin coating—the thicker the tin, the better—even tinplate with the same tin coating can exhibit inconsistent gloss between production batches due to the surface topography and roughness requirements of the cold-rolled sheet. Surface gloss is typically determined by the naked eye, a subjective perception.

[0003] There is a gloss meter currently on the market that uses a certain light source to illuminate the plate surface and a receiver to receive the intensity of the light reflected from the plate surface to quantitatively evaluate the brightness. Although this method can provide quantitative detection, it must be used when the tinplate plate is offline and static. This is because the test instrument must be tightly attached to the plate surface to prevent light leakage, otherwise it will affect the intensity of the received light and affect the measurement results. Currently, there is a lack of a simple and convenient device that can detect the brightness of tinplate plates. Utility Model Content

A light source is suspended above the marking rod, and the marking rod is projected on the object to be tested by the light source. The observer faces the mirror and can see the shadow projected in the mirror. Due to the different brightness of the object to be tested, the projection clarity of the grade mark on the marking rod on the object to be tested is also different. If the plate surface is bright, the reflection of light is more obvious, and the mark on the upper position of the marking rod, such as grade D, can be clearly seen on the shadow in the mirror. If the plate surface is dim, only the mark on the lower position of the marking rod, such as grade A, can be seen on the shadow in the mirror. That is, the brightness level of the object to be tested is determined by clearly reading the mark of the marking rod displayed by the shadow in the mirror, thereby realizing convenient and visual detection of the brightness of the tinplate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments.

[0026] Figure 2 This is a schematic diagram of the structure of the utility model Figure 2 . DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] A convenient visual tinplate brightness tester, including

[0029] A base 1 is provided for placing the tinplate to be tested, and a support rod 8 is provided on the base; the support rod can be folded relative to the base and can also be detached relative to the base;

[0030] a panel 2 hinged to the base 1 to be unfolded relative to the base 1 to a mutually perpendicular detection position, or folded relative to the base 1 to a mutually overlapping folded position;

[0031] a mirror 3, which is provided on the panel 2;

[0032] A marking rod 4, which is used to stand upright on the tinplate steel plate 9 to be tested;

[0033] The light source 5 is provided on the base 1 and is used to be suspended above the marking rod 4. The light source in this embodiment is an LED lamp with a power of 13W and an illumination of 750lx.

[0034] The base 1 is provided with scale lines 6, and the marking rod 4 is provided with grade marks 7 equidistantly arranged from bottom to top.

[0035] The utility model provides a convenient visual tinplate brightness tester. When it is needed, the object to be tested (i.e., tinplate steel plate) is placed flat and centered on a base, a marking rod is placed on the object to be tested, and the distance between the marking rod and the mirror is adjusted until the marking rod can be fully displayed in the mirror. A light source is suspended above the marking rod, and the marking rod is used to project a shadow 10 on the object to be tested. The observer faces the mirror and can see the shadow 11 projected in the mirror. Due to the different brightness of the object to be tested, the clarity of the projection of the grade mark on the marking rod on the object to be tested is also different. If the plate surface is bright, the reflection of light is more obvious, and the mark at the upper position of the marking rod, such as grade D, can be clearly seen on the shadow in the mirror. If the plate surface is dim, only the mark at the lower position of the marking rod, such as grade A, can be seen on the shadow in the mirror. That is, the brightness level of the object to be tested is determined by clearly reading the mark of the marking rod displayed by the shadow in the mirror. The whole process is simple to operate and realizes convenient and visual detection of the brightness of tinplate.

[0036] The advantages of reading the shadow through a mirror rather than directly observing the projection are as follows:

[0037] 1. The marking rod can be placed vertically on the object being measured. Because of this placement, direct observation of the projection will be affected by the rod itself. The closest reflection to the object will also affect the observation of reflections farther away. If the marking rod is tilted, the angle needs to be found, requiring manual support. Instability can also lead to errors. Tilts can also make it difficult to ensure uniformity and distinctness of the marking.

[0038] 2. The observer can observe from a wider range of angles. Direct observation of the projection requires viewing at certain specific angles because the object being measured has brightness, but the surface of the object being measured is not a perfect mirror and there will be diffuse reflection, which affects the viewing angle. Observation through a mirror allows observation at any angle.

[0039] Furthermore, as a preferred embodiment of this solution but not limiting, the panel 2 is provided with a lock 21, and the base 1 is provided with a buckle 22 corresponding to the lock 21. When the lock 21 engages with the buckle 22, the panel 2 remains in the folded position. After being locked, it is easy to store and reduces the volume.

[0040] Furthermore, as a preferred embodiment of the present invention but not limiting, a handle 13 is provided on the base 1 for easy carrying after folding.

[0041] Furthermore, as a preferred embodiment of the present invention but not limiting, a cavity 14 is provided on the base 1, and the cavity 14 is used to accommodate the marking rod 4 and the light source 5, thereby improving portability and making it easier to carry.

[0042] Furthermore, as a preferred embodiment of the present invention but not limiting, the marking rod 4 is cylindrical, and the grade mark 7 is arranged on the marking rod 4. The grade mark is visible at any angle along the circumference of the cylinder.

[0043] Furthermore, as a preferred embodiment of this solution but not limiting, the length of the marker rod 4 is greater than or equal to 15 cm. A marker rod that is too short will not be able to detect tinplate with high tin content, and a marker rod that is too long will be wasteful and take up space.

[0044] Furthermore, as a preferred embodiment of this solution but not limiting, the marking rod 4 is a multi-section telescopic rod, and the grade marks 7 on each section are A, B, C, D, and E. In addition, more levels of marks, such as F, G, H, etc., can be provided as needed.

[0045] Furthermore, as a preferred embodiment of the present invention but not a limitation, a slot 15 is provided on the base 1, and the bottom of the support rod 8 is inserted into the slot 15 to support it to stand upright relative to the base 1, and the bottom of the support rod slides with the slot 15 to allow the support rod 8 to move relative to the base 1, and the support rod 8 is folded relative to the base 1 to be accommodated in the cavity 14.

[0046] Furthermore, as a preferred embodiment of the present invention but not a limitation, the support rod 8 includes a lifting portion 81 and a transverse portion 82 hinged to the lifting portion 81 , the lifting portion 81 and the transverse portion 82 are both retractable, and the light source 5 is provided on the transverse portion 82 .

[0047] Furthermore, as a preferred embodiment of the present invention but not limitation, a magnet is provided at the bottom of the marking rod 4 , and the magnet is used to be adsorbed on the tinplate to be tested to support the marking rod 4 to stand upright.

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
