Description

Technical Field

[0001] The utility model relates to the technical field of concrete labels, in particular to a two-dimensional code anti-replacement label based on a water-soluble base. Background Art

[0002] Concrete is widely used in construction at this stage, and the quality requirements for concrete are different for different construction requirements. In order to ensure the quality of concrete, it is necessary to produce concrete specimens of corresponding specifications for inspection and testing to determine the quality of the concrete. In order to avoid the concrete specimens being replaced or confused, labels need to be pasted. At present, concrete test block labels are mainly bonded by glue, which has poor stability and is easy to be replaced, and has low safety. Therefore, in response to the above problems, a QR code anti-replacement label based on a water-soluble base is designed to better meet actual use needs. Utility Model Content

[0003] The purpose of the utility model is to provide a two-dimensional code anti-substitution label based on a water-soluble base to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a two-dimensional code anti-substitution label based on a water-soluble base, comprising a plastic base, a water-soluble film, a two-dimensional code layer and a concrete specimen, the lower end surface of the plastic base is provided with a barb structure, and the barb structure on the lower end surface of the plastic base is inserted into the concrete specimen for fixation, the lower end surface of the plastic base is bonded with a water-soluble film, the water-soluble film and the lower end surface of the plastic base are both sprayed with a two-dimensional code layer, and the two-dimensional code layer is in contact with the concrete specimen.

[0005] Preferably, the plastic base is made of a transparent material, and the plastic base can achieve the protective effect of the water-soluble film and the two-dimensional code layer.

[0006] Preferably, the water-soluble film material is a transparent material that melts when in contact with water but is solid when dry. By limiting the material of the water-soluble film, it is convenient to check the QR code layer later.

[0007] Preferably, the material of the water-soluble film is hydrosol. By limiting the material of the water-soluble film, the stability of the later fixation of the two-dimensional code layer can be facilitated.

[0008] Preferably, the two-dimensional code layer is made by spraying water-insoluble ink.

[0009] Compared with the prior art, the beneficial effect of the utility model is that the QR code anti-substitution label based on the water-soluble base utilizes the inherent characteristics of the water-soluble film and the function of the QR code layer to form a self-adhesive label structure, which can make the QR code layer fully or partially integrated with the concrete specimen. Compared with traditional adhesive labels, the self-adhesive label of the present application can not only ensure the clarity of the identification, but also effectively prevent the label from being replaced, thereby ensuring the effectiveness of use.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-Figure 3 The utility model provides a technical solution: a two-dimensional code anti-substitution label based on a water-soluble base, comprising a plastic base 1, a water-soluble film 2, a two-dimensional code layer 3 and a concrete specimen 4, the lower end surface of the plastic base 1 is provided with a barb structure, and the barb structure on the lower end surface of the plastic base 1 is inserted into the concrete specimen 4 for fixation, the lower end surface of the plastic base 1 is bonded with the water-soluble film 2, the water-soluble film 2 and the lower end surface of the plastic base 1 are sprayed with the two-dimensional code layer 3, and the two-dimensional code layer 3 is in contact with the concrete specimen 4.

[0016] The plastic base 1 is made of a transparent material; the water-soluble film 2 is made of a transparent material that melts when exposed to water but is solid when dry; the material of the water-soluble film 2 is preferably a hydrosol; the two-dimensional code layer 3 is made by spraying water-insoluble ink;

[0017] The two-dimensional code anti-substitution label based on a water-soluble base comprises the following steps: Embodiment 1

[0018] Label production: Figure 1 and Figure 2As shown, a transparent water-soluble film 2 is fixed on a plastic base 1, and a two-dimensional code layer 3 is sprayed on the water-soluble film 2 and the plastic base 1 using ordinary ink, so that the two-dimensional code layer 3 on the water-soluble film 2 and the two-dimensional code layer 3 on the plastic base 1 form a complete two-dimensional code (wherein the two-dimensional code layer 3 on the water-soluble film 2 only occupies a small part of the whole two-dimensional code, that is, after the water-soluble film 2 is dissolved, the two-dimensional code is prevented from being deformed, which affects the subsequent two-dimensional code recognition);

[0019] Use of label: Under the witness of the witness, the sampler presses the QR code layer 3 of the label onto the wet concrete specimen 4. At this time, the barb structure on the lower end of the plastic base 1 is inserted into the wet concrete specimen 4. At this time, due to the inherent characteristics of the water-soluble film 2 (dissolved in water), after the QR code layer 3 on the water-soluble film 2 is pressed onto the surface of the wet concrete specimen 4, the water-soluble film 2 will dissolve, thereby attaching the QR code layer 3 on the water-soluble film 2 to the surface of the concrete specimen 4. When the concrete specimen 4 is not solidified, due to the water-soluble The two-dimensional code layer 3 on the film 2 is attached to the surface of the concrete specimen 4. Even if the label is removed manually, the two-dimensional code layer 3 cannot be completely removed. Only part of the two-dimensional code layer 3 on the lower end surface of the plastic base 1 can be removed to achieve the effect of preventing replacement. When the concrete specimen 4 solidifies, the pattern of the two-dimensional code layer 3 on the surface has been finalized. At this time, the two-dimensional code layer 3 on the lower end surface of the plastic base 1 and the two-dimensional code layer 3 on the lower end surface of the water-soluble film 2 are combined to form a complete two-dimensional code, so as to facilitate subsequent two-dimensional code recognition, and the remaining plastic base 1 can also prevent the two-dimensional code layer 3 from being worn; Embodiment 2

[0020] Label production: Figure 3 As shown, a transparent water-soluble film 2 is fixed on a plastic base 1, and a two-dimensional code layer 3 is sprayed all over the water-soluble film 2 using ordinary ink to form a completed label;

[0021] Usage of the label: Under the witness of the witness, the sampler presses the QR code layer 3 on the water-soluble film 2 onto the wet concrete specimen 4. At this time, due to the characteristics of the water-soluble film 2 itself (dissolves in water), after the QR code layer 3 on the water-soluble film 2 is pressed on the surface of the wet concrete specimen 4, the water-soluble film 2 will dissolve, thereby attaching the QR code layer 3 on the water-soluble film 2 to the surface of the concrete specimen 4. When the concrete specimen 4 is not solidified, the water-soluble film 2 dissolves at this time, so that the QR code layer 3 on the water-soluble film 2 adheres to the surface of the concrete specimen 4. Even if the label is removed manually, it is difficult to completely remove the QR code layer 3, thereby achieving the effect of anti-replacement. This is the working principle of the QR code anti-replacement label based on the water-soluble base.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
