[0002] The scratch and heat stamping film, also known as scratch silver, is a special material applied to printed matter. It is a layer of scratchable layer attached to the printed matter to cover the printed content below. The application of the scratch and heat stamping film is very extensive and is commonly found in anti-counterfeiting labels, such as recharge card passwords, product serial numbers, etc., which can effectively prevent information leakage.

[0003] After the scraping layer is printed, it is necessary to conduct scraping detection on the scraping layer, such as testing whether the scraping layer is easy to scrape off and the stability of the scraping layer, so as to control the product quality or adjust the production process. The existing detection method is that the staff uses their nails to conduct scraping tests on the scraping layer. Due to differences in the hardness of the operator's nails, scraping angles, and applied forces, there are subjective differences in the judgment results, which is not conducive to production personnel and quality personnel to conduct quality inspection and judgment on the scraping layer. Therefore, there is an urgent need for a scraping layer testing tool to improve the objectivity and accuracy of scraping layer inspection. Summary of the Utility Model

[0004] This application proposes a scraping layer testing tool to improve the objectivity and accuracy of scraping layer scraping inspection.

[0005] To achieve the above object, the utility model provides the following technical solutions:

An installation hole is provided at the upper part of the inclined groove. A sleeve is connected to the bottom surface of the installation hole. A pin is inserted into the sleeve. The bottom end of the pin passes through the sleeve and inserts into the inclined groove to abut against the scraping blade. The top of the pin is connected to one end of a spring, and the bottom surface of the installation hole is connected to the other end of the spring.

[0007] In an embodiment of this application, concave holes are opened on both sides of the body.

[0008] In an embodiment of this application, a loading groove is opened at the top of the body.

[0009] In an embodiment of this application, a bolt column is provided in the loading groove, and a weight block and a nut are sleeved on the bolt column.

When in use, align the protruding end of the scraping blade 111 with the scraping layer to be tested, and push the main body 1 horizontally so that the protruding end of the scraping blade 111 slides across the scraping layer, thereby completing the scraping test of the scraping layer. The same main body 1 can be used to perform scraping tests on different scraping layers respectively. Since the hardness of the same scraping blade 111 is the same, and the scraping angle of the scraping blade 111 fixed in the inclined slot 11 is the same, and the mass of the same main body 1 is the same so that the pressing force of the scraping blade 111 is the same, compared with using a fingernail to scrape and inspect the scraping layer, it improves the objectivity and accuracy of the scraping layer inspection, and thus is beneficial to improving the efficiency of production personnel and quality personnel in judging the quality of the scraping layer.

[0034] In an embodiment of the present application, referring to Figure 1 and Figure 2 as shown, concave holes 4 are formed on both sides of the main body 1.

[0035] In the above embodiment, the concave holes 4 can form a holding point on the side of the main body 1, which can increase the stability of holding when transferring or pushing the main body 1, prevent the main body 1 from falling during transfer and taking, and is beneficial to improving the safety of the tool.

[0036] In an embodiment of the present application, referring to Figure 4 as shown, a loading groove 5 is formed at the top of the main body 1.

[0037] In the above embodiment, the loading groove 5 opened at the top of the main body 1 is used to place standard weights such as weights, so as to change the self-weight of the main body 1, and further change the force for the scraping blade 111 to scrape the scraping layer, so as to realize the inspection of the same batch of scraping layers with different scraping forces, which is beneficial to improving the accuracy of detection, and further beneficial to improving and adjusting the printing process of the scraping layer.

[0038] In an embodiment of the present application, referring to Figure 5 As shown, a bolt column 51 is arranged in the loading groove 5, and a counterweight block 52 and a nut 53 are sleeved on the bolt column 51.

The counterweight block 52 is placed in the loading groove 5 through the bolt column 51, and then the nut 53 is screwed in to clamp the counterweight block 52, which is beneficial to improving the stability of the counterweight block 52, and further beneficial to improving the inspection efficiency of the scraping layer.

[0040] In an embodiment of the present application, referring to Figure 2 As shown, fine grooves 12 are provided on the inner wall of the inclined groove 11.

[0041] In the above embodiment, the fine grooves 12 are used to increase the friction between the scraping blade 111 and the inclined groove 11 when the scraping blade 111 is inserted into the inclined groove 11, which is beneficial to improving the stability of the scraping blade 111 inserted in the inclined groove 11.

[0042] In an embodiment of the present application, referring to Figure 6 As shown, a rounded chamfer 6 is provided on the edge of the lower part of the main body 1.

[0043] In the above embodiment, the edge of the lower part of the main body 1 is relatively sharp, and it is easy to scratch the paper surface or leave scratches on the paper surface when sliding on the paper surface. The rounded chamfer 6 is relatively smooth, which can prevent the edge from scratching the test paper.

[0044] In an embodiment of the present application, referring to Figure 7 As shown, a roller 7 is installed on the bottom surface of the main body 1.

[0045] In the above embodiment, a roller 7 is installed on the bottom surface of the main body 1. The roller converts the sliding friction of the main body 1 on the paper surface into rolling friction. On the one hand, it reduces the traveling resistance of the main body 1 when translating on the paper surface and improves the smoothness of the main body 1 moving on the paper surface. On the other hand, it reduces the contact area between the bottom surface of the main body 1 and the paper surface and prevents the paper surface from being scratched by the bottom surface of the main body 1.

[0046] During the actual use of this application: Before inspection, place the paper with a scraping layer flat on the desktop, align the protruding end of the scraping blade 111 with the scraping layer to be tested, and push the main body 1 horizontally so that the protruding end of the scraping blade 111 slides across the scraping layer, thereby completing the scraping test of the scraping layer. The same main body 1 can be used to perform scraping tests on different scraping layers respectively. The hardness of the same scraping blade 111 is the same, and the scraping blade 111 is fixed in the inclined groove 11 with the same scraping angle. The mass of the same main body 1 is the same, so that the pressing force of the scraping blade 111 is the same. In addition, pulling up the retaining pin 22 can pull out the scraping blade 111. When the scraping blade 111 is inserted into the inclined groove 11 again, first pull up the retaining pin 22 to insert the scraping blade 111, and then release the retaining pin 22. The spring 3 pulls the retaining pin 22 to reset and press against the scraping blade 111 again to tightly fix the scraping blade 111, which is convenient for replacing the scraping blade 111. Different hardness scraping blades 111 can be replaced to test the scraping layer. Removing the scraping blade 111 is also convenient for cleaning the scraping layer residue on the scraping blade 111 to avoid the influence of residues on the inspection of the scraping layer.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, rather than to limit them; although this application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of this application.
