Description

Technical Field

[0001] The utility model relates to the technical field related to ink research and development testing, and in particular to a novel device for testing the thermal migration of ink. Background Art

[0002] For example, cigarette cartons are wrapped with film using a heat shrink process. During this process, the surface of the cigarette carton is subjected to heat, requiring that the printed ink on the cigarette carton not migrate due to heat. That is, the ink on the cigarette carton must not evaporate and stain the packaging film when heated. Therefore, when developing printing ink formulations, it is crucial to test the ink's thermal migration properties. The current testing method involves printing a pattern on a paper card with the developed ink, then covering the card with a layer of packaging film. Researchers then blow directly at the packaging film with a hair dryer for a period of time, observing the inner surface of the film for any mist caused by ink migration. While this method provides a simple way to test ink thermal migration, it cannot measure the thermal migration of the ink under different heating distances and temperatures. To address this issue, we have developed a new device for testing ink thermal migration properties. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0017] Combined with attachment Figure 1 As shown, a novel device for testing the thermal migration of ink includes a drying mechanism 10 and a spacing adjustment mechanism 20. The spacing adjustment mechanism 20 is equipped with a paper card insertion rack 21 that moves relative to the drying mechanism 10. The spacing adjustment mechanism 20 includes a movable base 22, flanked by a guide rod assembly 23 and a linear motor 24. The left and right sides of the movable base 22 are connected to sliders 231 of the guide rod assembly 23 and a sliding base 241 of the linear motor 24, respectively. The paper card insertion rack 21 is fixedly mounted to the movable base 22. The spacing adjustment mechanism 20 uses the movable base 22 to change the relative position between the paper card insertion rack 21 and the drying mechanism 10, thereby testing the thermal migration of ink under different heating distance conditions.

[0018] Combined with attachment Figure 1 To the attached Figure 4 As shown, the heat drying mechanism 10 includes a heat drying gun 11, a base 12, a switch contact 13, and a deflection frame 14. The base 12 is provided with a mounting bracket 15, an upper connecting member 16, and a lower supporting member 17 for mounting the heat drying gun 11. The mounting bracket 15 is fixedly installed on the base 12. The heat drying gun 11 is clamped between the upper connecting member 16 and the lower supporting member 17. The lower supporting member 17 is specifically provided with an inner supporting pad 171 that contacts the heat drying gun 11. The material of the inner supporting pad 171 is silicone.

[0019] Combined with attachment Figure 2 and attached Figure 3As shown, one end of the upper connecting member 16 is fixedly connected to the mounting bracket 15, and the switch contact 13 is slidably mounted on the other end of the upper connecting member 16. The switch contact 13 is movably engaged with the deflection frame 14. The upper end of the deflection frame 14 is connected to the telescopic rod 181 of the driving cylinder 18, and the lower end of the deflection frame 14 is hinged to the hinge frame 121 of the base 12. The base 12 is specifically provided with a cylinder mounting frame 19, and the cylinder mounting frame 19 is hingedly connected to a cylinder mounting plate 191. The cylinder body 182 of the driving cylinder 18 is fixedly mounted on the cylinder mounting plate 191. The telescopic rod 181 of the driving cylinder 18 is provided with a Y-type joint 183, and the Y-type joint 183 is hinged to the upper end of the deflection frame 14.

[0020] Combined with attachment Figure 5 As shown, one end of the upper connecting member 16 is provided with a connecting plate portion 161 for connecting to the mounting bracket 15, and the other end of the upper connecting member 16 is provided with a circular arc-shaped guide plate portion 162, and the left and right sides of the guide plate portion 162 are provided with connecting wings 163 for connecting to the lower support member 17.

[0021] Since the switch contact 13 is specifically cylindrical, a central through hole 131 is opened in the switch contact 13, and the central through hole 131 is slidably connected to the guide plate portion 162 of the upper connecting member 16. The switch contact 13 can slide along the guide plate portion 162 of the upper connecting member 16. A button portion 132 for pressing the switch button 111 of the hot drying gun 11 is provided inside the end of the central through hole 131. A groove 133 is opened on the outer surface of the switch contact 13, and the deflection frame 14 is provided with a pin member 134 for clamping the groove 133.

[0022] Combined with attachment Figure 2 and attached Figure 3 As shown, when the telescopic rod 181 of the driving cylinder 18 extends outward, the telescopic rod 181 pushes the deflection frame 14 downward. As the deflection frame 14 swings downward, it drives the switch contact 13 to slide along the guide plate portion 162 of the upper connecting member 16. The button portion 132 of the switch contact 13 presses the switch button 111 of the heat drying gun 11, thereby turning the heat drying gun 11 on and off. During testing, different heat drying temperatures can be achieved by simply varying the current flowing through the heating wire of the heat drying gun 11, thereby enabling thermal migration testing of ink under different heating temperature conditions.

[0023] As attached Figure 1As shown, the present invention further includes a data acquisition component 30 for recording test results, and a computer control component. The data acquisition component 30 includes a CCD camera 31 and a camera mounting bracket 32. The CCD camera 31 faces the paper card insertion rack 21, and the camera mounting bracket 32 ​​is fixedly mounted on the base 12. The computer control component includes a display 41, a keyboard 42, and a mouse 43. The data acquisition component 30 photographs each test paper card 50 to record the results of each ink thermal migration test and transmits the photographed images to the computer control component for storage and analysis, completing data acquisition and analysis, thereby realizing the digitization of the ink thermal migration test process.
