Description

Technical Field

[0001] This utility model relates to ink layer fastness testing, and in particular to a device for testing the fastness of printed ink layers. Background Technology

[0002] Ink printing refers to the process of printing ink patterns onto paper using printing equipment, such as printed works of art. After ink printing, an ink pattern is formed on the paper material; therefore, the stability of the ink, such as its adhesion to the paper material, is crucial to the lifespan of ink-printed products.

[0003] Printed products are frequently subjected to friction during use. Therefore, for printed materials with poor ink adhesion, the ink is prone to peeling off the paper with increasing friction, leading to discoloration. Thus, after printing, it is necessary to conduct abrasion resistance testing on the printed materials to determine the ink's adhesion to the paper material.

[0004] However, in the existing technology, when testing the printing ink layer, the test is usually carried out only at normal temperature, which means that the test results are not applicable to the fastness of the printing ink layer in high temperature or special environments. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device for testing the fastness of printing ink layers. When testing printing ink layers, the test is usually carried out only at normal temperature, which makes the test results not applicable to the fastness of printing ink layers in high temperature or special environments.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An apparatus for testing the adhesion of printing ink layers includes a testing chamber. A water inlet pipe is movably installed on the front side of the testing chamber and is connected to the interior of the testing chamber. A drain pipe is movably installed on one side of the testing chamber near the bottom and is connected to the interior of the testing chamber. A testing platform is movably installed inside the testing chamber. Heaters are fixedly installed on both sides of the bottom of the testing chamber, and heating tubes are fixedly installed on the outer ends of the heaters. The heating tubes are arranged in an S-shape at the bottom of the testing chamber.

[0008] Preferably, two fixed platforms are fixedly installed on the top of the testing box, and a servo motor is fixedly installed on one side of each fixed platform. The output end of the servo motor is connected to a lead screw through a coupling, and one end of the lead screw is rotatably connected to the surface of the fixed platform.

[0009] Preferably, a movable plate is movably mounted on the outer surface of the lead screw, and two connecting rods are fixedly mounted on the bottom end of each movable plate. A detection scraper is fixedly connected between the two connecting rods, and a detection grinding roller is rotatably connected between the other two connecting rods.

[0010] Preferably, an electric push rod is fixedly installed at the center of the bottom of the testing box, the output end of the electric push rod is fixedly connected to the bottom of the testing platform, and a sealing ring is movably installed at the bottom of the testing box near the output end of the electric push rod.

[0011] Preferably, support columns are fixedly installed at the four corners of the bottom of the testing box.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By combining the water inlet pipe and the water outlet pipe, water can be injected into the test chamber through the water inlet pipe during use, so that the printed ink layer to be tested can be tested separately in water and under normal conditions, improving the test accuracy. During the test, the heater can be heated by the lead screw to raise the water temperature, so that different temperature environments can be used for the test of printed ink in water, thus improving the test accuracy.

[0014] 2. By using the cooperation of the detection scraper and the detection grinding roller, when inspecting the printed ink layer, the printed ink layer can be placed on the surface of the inspection table, and the detection scraper and the detection grinding roller can be used to scrape and rub one-third of the printed ink layer respectively. After the inspection, the ink layer's resistance to scraping and rubbing can be tested by comparing the differences between the three areas on the surface of the printed ink layer: the area scraped by the detection scraper, the area not scraped, and the area rubbed by the detection grinding roller. This improves the inspection efficiency and makes it easier for personnel to compare the inspection results.

[0015] 3. By cooperating with the electric push rod and the detection table, the device can drive the detection table to rise and fall during use. This allows the height of the detection table to be adjusted according to the position of the printed ink layer, so that the printed ink layer can be scraped and rubbed by the detection scraper and detection grinding roller, avoiding the situation where the object being tested is too high or too low and cannot be detected.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1 As shown, an apparatus for testing the adhesion of printing ink layers includes a testing chamber 1. A water inlet pipe 2 is movably installed on the front side of the testing chamber 1 and is connected to the interior of the testing chamber 1. A drain pipe 3 is movably installed on one side of the testing chamber 1 near the bottom and is connected to the interior of the testing chamber 1. A testing platform 6 is movably installed inside the testing chamber 1. Heaters 13 are fixedly installed on both sides of the bottom of the testing chamber 1. Heating tubes 14 are fixedly installed on the outer ends of the heaters 13. The heating tubes 14 are arranged in an S-shape at the bottom of the testing chamber 1.

[0023] Support columns 4 are fixedly installed at the four corners of the bottom of the test box 1.

[0024] In this embodiment, the combination of the water inlet pipe 2 and the drain pipe 3 allows water to be injected into the test chamber 1 through the water inlet pipe 2 during use. This enables the printing ink layer to be tested to be immersed in water and tested under normal conditions, thereby improving the testing accuracy. During testing, the heater 13 can be heated by the lead screw 12 to raise the water temperature, allowing different temperature environments to be used for testing the printing ink in water, thus improving the testing accuracy.

[0025] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, two fixed platforms 7 are fixedly installed on the top of the testing box 1. A servo motor 8 is fixedly installed on one side of each fixed platform 7. The output end of the servo motor 8 is connected to a lead screw 12 through a coupling. One end of the lead screw 12 is rotatably connected to the surface of the fixed platform 7.

[0026] An electric push rod 5 is fixedly installed at the center of the bottom of the test box 1. The output end of the electric push rod 5 is fixedly connected to the bottom of the test platform 6. A sealing ring is movably installed at the bottom of the test box 1 near the output end of the electric push rod 5.

[0027] In this embodiment, the electric push rod 5 and the detection platform 6 work together to allow the device to be used so that the detection platform 6 can be raised and lowered by the electric push rod 5. This allows the height of the detection platform 6 to be adjusted according to the position of the printing ink layer, so that the printing ink layer can be scraped and rubbed by the detection scraper 11 and the detection grinding roller 15, thus avoiding the situation where the object being tested is too high or too low and cannot be detected.

[0028] As a preferred technical solution in this embodiment, such as Figure 4 As shown, movable plates 9 are movably mounted on the outer surface of the lead screw 12. Two connecting rods 10 are fixedly mounted on the bottom end of each movable plate 9. A detection scraper 11 is fixedly connected between the two connecting rods 10, and a detection grinding roller 15 is rotatably connected between the other two connecting rods 10.

[0029] In this embodiment, by cooperating with the detection scraper 11 and the detection grinding roller 15, when inspecting the printed ink layer, the printed ink layer can be placed on the surface of the detection table 6, and the detection scraper 11 and the detection grinding roller 15 can be used to scrape and rub one-third of the printed ink layer respectively. After the inspection, the ink layer's resistance to scraping and rubbing can be tested based on the differences between the three areas on the surface of the printed ink layer: the area scraped by the detection scraper 11, the area not scraped, and the area rubbed by the detection grinding roller 15. This improves the inspection efficiency and makes it easier for personnel to compare the inspection results.

[0030] Working principle: First, the object to be tested is placed on the surface of the detection stage 6, and the detection stage 6 is raised and lowered by the electric push rod 5. The height of the detection stage 6 can be adjusted according to the position of the printing ink layer, so that the printing ink layer can be scraped and rubbed by the detection scraper 11 and the detection grinding roller 15, avoiding the situation where the object to be tested is too high or too low and cannot be detected.

[0031] Subsequently, when inspecting the printed ink layer, the ink layer can be placed on the surface of the inspection table 6, and the inspection scraper 11 and the inspection grinding roller 15 can be used to scrape and rub one-third of the ink layer, respectively. After the inspection, the ink layer's resistance to scraping and rubbing can be tested by comparing the differences between the three areas on the ink layer surface: the area scraped by the inspection scraper 11, the unscraped area, and the area rubbed by the inspection grinding roller 15. This improves inspection efficiency and facilitates comparison of test results.

[0032] During testing, water can be injected into the testing chamber 1 through the water inlet pipe 2, allowing the tested printing ink layer to be tested for fastness under conditions of immersion in water and normal conditions, thereby improving testing accuracy. Furthermore, during testing, the heater 13 can be heated by the lead screw 12 to raise the water temperature, allowing different temperature environments to be used for testing the printing ink in water, thus improving testing accuracy.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
