Description

Technical Field

[0001] The utility model relates to the technical field of tinplate detection, in particular to a 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 stationary. 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-to-use device that can be used both online and offline to detect the brightness of tinplate plates. Utility Model Content

The whole process is simple to operate, and convenient and visual detection of the brightness of the tinplate is achieved. 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.

[0025] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0026] 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.

[0027] A visual tinplate brightness detector, comprising

[0028] Base 1, on which the tinplate to be tested is placed;

[0029] A panel 2 is vertically arranged relative to the base 1;

[0030] The side panel 12, which, together with the base 1 and the panel 2, forms a box body with an open front;

[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 to be tested;

[0033] The light source 5 is provided on the side panel 12 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 visual tinplate brightness tester. When it is needed, the object to be tested, i.e., a tinplate steel plate, is flatly laid and centered on a base, a marking rod is placed on the object to be tested, and the distance between the marking rod and a 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. An observer facing the mirror can see a 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 a convenient and visual detection of the brightness of the tinplate is achieved.

[0036] The advantages of reading the shadow through a mirror instead of 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 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, thereby improving portability and making it easier to carry.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Furthermore, as a preferred embodiment of the present invention but not limiting, a slot 15 and a sliding member 8 that slides with the slot 15 and drives the light source 5 to move are provided on the top of the top plate, so as to facilitate adjustment of the lighting position.

[0044] Furthermore, as a preferred embodiment of this solution but not a limitation, the sliding member 8 passes through the top surface of the top plate, so as to facilitate the operation of the sliding member and thus move the position of the light source.

[0045] 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.

[0046] 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.
