Description

Technical Field

[0001] This utility model belongs to the field of ink adhesion testing technology, and specifically relates to an ink adhesion testing machine. Background Technology

[0002] In the board processing and production process, printing ink is a crucial step, widely used in packaging, building materials, electronics, and many other industries. To ensure the clarity, durability, and aesthetics of the printed pattern, the ink must firmly adhere to the board surface; therefore, ink adhesion testing is an indispensable part of the production process. Through testing, the bonding strength between the ink and the board can be evaluated, ensuring that the product meets quality standards. Traditional testing methods include the tape method and the cross-cut test; for example, Chinese patent application number CN202322449263.8 uses a drive motor to move a corresponding structure, thereby moving a roller. The roller rotates simultaneously, causing double-sided adhesive tape on its surface to adhere to the ink on the PCB board. The degree of ink detachment is then observed to determine whether the ink adhesion meets the standard requirements.

[0003] However, in actual use, after a period of testing, the tape on the outer periphery of the roller is prone to dust accumulation, which reduces its stickiness and can affect the accuracy of the test results. Therefore, the tape on the roller periphery needs to be replaced manually and periodically. In addition, the tape in the above patent is glued and fixed to the outer periphery of the roller, making it difficult to tear off the tape quickly. Therefore, the existing technology has the problem of not being convenient to replace the tape on the outer periphery of the roller. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an ink adhesion testing machine that solves the problem of inconvenience in replacing the tape on the outer peripheral wall of the roller in existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An ink adhesion tester for testing the ink adhesion of printing inks on printing plates, including rollers;

[0007] The drum is a sealed shell with a hollow interior. A strip groove is provided on the upper peripheral wall of the drum. The strip groove is placed coaxially with the drum and is connected to the through interior.

[0008] The drum is equipped with a rotating roller and a take-up roller that are rotatably connected. Both the rotating roller and the take-up roller are placed in the same axial direction as the drum. A roll of tape is fixedly sleeved on the rotating roller.

[0009] The tape at the free end of the tape roll extends out of the roller from one side of the strip groove and extends along the outer peripheral wall of the lower end of the roller to the other side of the strip groove and into the roller, and the tape at the free end of the tape roll is fixed to the peripheral wall of the take-up roller.

[0010] When the tape extends to the outer peripheral wall of the lower end of the roller, the adhesive surface of the tape is located on the side away from the central axis of the roller;

[0011] Separator strips are adhered to both sides of the adhesive surface of the tape along the axis of the roller, and the separator strips are arranged along the extension direction of the tape.

[0012] Mounting plates are fixed on the inner walls of both ends of the roller. Electric push rods are fixed on both sides of the mounting plates. The electric push rods are placed perpendicular to the central axis of the roller. The output ends of the electric push rods on both sides of the mounting plates face the groove walls on both sides of the groove parallel to the central axis of the roller. Pressure blocks are fixed on the output ends of the electric push rods.

[0013] A first rotating motor connected to a take-up roller is fixedly installed at either end of the drum; both ends of the drum are rotatably connected to rotating shafts, which are placed coaxially with the drum.

[0014] The lower end of each rotating shaft is equipped with a horizontally placed slide rail, which is perpendicular to the central axis of the drum. A slider is slidably connected inside the drum. A support block is fixedly sleeved on the end of the rotating shaft away from the drum. The slider and the support block on the corresponding side are connected by an adjustment part, which is used to drive the support block to move up and down.

[0015] A screw is rotatably connected within any slide rail and placed coaxially. The screw passes through the slider on the corresponding side and is threadedly connected to the slider. A second rotary motor for driving the screw to rotate is fixedly installed at either end of the slide rail.

[0016] The adjustment unit includes a telescopic cylinder that is vertically fixed on the slider, and the output end of the telescopic cylinder is fixed to the support block.

[0017] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0018] Rotary connection: refers to a connection where two parts can rotate relative to each other, and is often used in mechanical devices when rotational motion is required.

[0019] Threaded connection: A method of connecting two parts together using a threaded structure. Threaded connections provide a strong connection and are relatively easy to disassemble and reconnect.

[0020] The beneficial effects of this utility model are:

[0021] 1. By setting up a hollow roller, and coordinating the internal rotating roller, winding roller and tape roll, the tape at the free end of the tape roll wraps around the outer peripheral wall of the lower end of the roller, driving the roller to roll along the surface of the board. The tape adheres to the ink on the surface of the board. Then, by observing the ink peeling off, the ink adhesion of the board can be tested.

[0022] After a period of testing, the tape on the outer periphery of the lower end of the roller is prone to dust accumulation, which causes a decrease in adhesion. The tape on the outer periphery of the lower end of the roller needs to be replaced. At this time, rotate the take-up roller, which drives the tape to take up, and the tape pulls the tape roll to release, so as to facilitate the replacement of the tape on the outer periphery of the roller.

[0023] 2. By setting separators on both sides of the tape, and in conjunction with the mounting plate, electric push rod and pressure block, during testing, the tape on the lower periphery of the roller can be kept taut by pressing the separators near the groove. This also prevents the tape roll from being accidentally pulled and released during the rolling test.

[0024] 3. The combination of a rotating shaft, slide rail, slider, support block, adjusting part, screw and second rotating motor facilitates the driving of the roller to roll along the surface of the sheet material; and the height between the slider and support block is controlled and adjusted by the adjusting part so that the tape on the lower peripheral wall of the roller contacts the sheet material, which is suitable for testing the ink adhesion of various sheets of different thicknesses.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] This combination Figures 1 to 5 This describes an embodiment of an ink adhesion testing machine. Specifically, the ink adhesion testing machine is constructed as a split structure, comprising components such as a roller 100, a strip groove 101, a rotating roller 200, a take-up roller 300, and a tape roll 400. After testing for a period of time, the tape on the outer peripheral wall of the lower end of the roller 100 is prone to dust accumulation, resulting in a decrease in adhesion. It is necessary to replace the tape on the outer peripheral wall of the lower end of the roller 100. At this time, rotating the take-up roller 300 causes the tape to be wound up, and the tape pulls the tape roll 400 to release, thereby facilitating the replacement of the tape on the outer peripheral wall of the roller 100.

[0033] Please refer to Figures 1 to 5 An ink adhesion tester is used to test the ink adhesion of printing inks on a printing plate, including a roller 100.

[0034] The roller 100 is a sealed shell with a hollow interior. A strip groove 101 is provided on the upper peripheral wall of the roller 100. The strip groove 101 is placed in the same direction as the roller 100 and is connected to the through interior.

[0035] The drum 100 is provided with a rotating roller 200 and a take-up roller 300 that are rotatably connected. The rotating roller 200 and the take-up roller 300 are both placed in the same direction as the drum 100. A tape roll 400 is fixedly sleeved on the rotating roller 200.

[0036] The tape at the free end of the tape roll 400 extends out of the roller 100 from one side of the strip groove 101 and extends along the outer peripheral wall of the lower end of the roller 100 to the other side of the strip groove 101 and enters the roller 100. The tape at the free end of the tape roll 400 is fixed to the peripheral wall of the take-up roller 300.

[0037] When the tape extends to the outer peripheral wall of the lower end of the roller 100, the adhesive surface of the tape is located on the side away from the central axis of the roller 100.

[0038] When using it, place the board material under the roller 100, and roll the roller 100 along the surface of the board material by hand or by mechanical means. The ink on the surface of the board material is adhered by the adhesive tape. Then, by observing the ink falling off, the ink adhesion of the board material can be tested.

[0039] After a period of testing, the tape on the outer periphery of the lower end of the roller 100 is prone to dust accumulation, which causes a decrease in adhesion. The tape on the outer periphery of the lower end of the roller 100 needs to be replaced. At this time, rotate the take-up roller 300, which drives the tape to be wound up. The tape pulls the tape roll 400 to release, thus facilitating the replacement of the tape on the outer periphery of the roller 100.

[0040] Separator strips 401 are attached to both sides of the adhesive surface of the tape along the axial direction of the roller 100. The separator strips 401 are arranged along the extension direction of the tape. Due to the adhesion between the adhesive surface of the tape and the board, when the roller 100 rolls along the surface of the board, it is easy to accidentally pull the tape roll 400 and release the tape. However, by setting the separator strips 401, during the test, the tape on the lower peripheral wall of the roller 100 can be kept taut by pressing the separator strips 401 near the strip groove 101. At the same time, it can prevent the tape roll 400 from being accidentally pulled and released during the rolling test.

[0041] It should be noted that the surface of the sheet to be tested is located between the two dividing strips 401; during a single roll of the roller 100, when the strip groove 101 is about to rotate to the lowest position of the roller 100's circumference, the roller 100 is stopped from being pushed.

[0042] To facilitate automatic pressing of the separator strip 401, mounting plates 500 are fixed on the inner walls of both ends of the roller 100. Electric push rods 501 are fixed on both sides of the mounting plates 500. The electric push rods 501 are placed perpendicular to the central axis of the roller 100. The output ends of the electric push rods 501 on both sides of the mounting plates 500 face the groove walls of the strip groove 101 parallel to the central axis of the roller 100. Pressing blocks 502 are fixed to the output ends of the electric push rods 501. During testing, the electric push rods 501 drive the pressing blocks 502 to approach the groove wall of the strip groove 101. The pressing blocks 502 press the separator strip 401 onto the groove wall of the strip groove 101, thus realizing the automatic pressing operation of the separator strip 401.

[0043] Preferably, the edge of the strip groove 101 near the upper part is provided with a rounded chamfer to reduce damage to the tape from the edge.

[0044] A first rotating motor 600 connected to the take-up roller 300 is fixedly installed at either end of the roller 100; by turning on the first rotating motor 600, the take-up roller 300 can be easily driven to rotate to take up the tape.

[0045] To facilitate the movement of the roller 100 along the surface of the sheet, both ends of the roller 100 are rotatably connected to a rotating shaft 700, which is placed coaxially with the roller 100. When the two rotating shafts 700 are driven to move along the surface of the sheet, the roller 100 can roll along the surface of the sheet.

[0046] Each of the rotating shafts 700 has a horizontally placed slide rail 800 at its lower end. The slide rails 800 are all perpendicular to the central axis of the roller 100. Each of the rollers 100 has a slider 801 slidably connected inside. Each of the rotating shafts 700 away from the roller 100 has a support block 802 fixedly sleeved on its end. The slider 801 and the support block 802 on the corresponding side are connected by an adjustment part 803. The adjustment part 803 is used to drive the support block 802 to move up and down. The slide rails 800 and sliders 801 improve the guiding performance of the roller 100 during movement. At the same time, the adjustment part 803 can adjust the height difference between the support block 802 and the slider 801. When the sheet is placed below the roller 100, the slider 801 can be adjusted up and down by the adjustment part 803 so that the tape at the bottom periphery of the roller 100 contacts the sheet.

[0047] To facilitate the automatic movement of the slider 801 and the roller 100, a screw 804 is rotatably connected within any slide rail 800 and placed coaxially. The screw 804 passes through the slider 801 on the corresponding side and is threadedly connected to the slider 801. A second rotary motor 805 for driving the screw 804 to rotate is fixedly installed at any end of the slide rail 800. By turning on the second rotary motor 805, the screw 804 is driven to rotate, and the screw 804 drives the slider 801 to perform threaded transmission.

[0048] The rotation direction of the second rotating motor 805 driving the screw 804 is switched so as to drive the slider 801 and the roller 100 to reciprocate.

[0049] The adjustment unit 803 includes a telescopic cylinder that is vertically fixed on the slider 801, and the output end of the telescopic cylinder is fixed to the support block 802. The telescopic cylinder can drive the slider 801 and the support block 802 to adjust the height, which is suitable for testing the ink adhesion of various boards of different thicknesses.

[0050] Preferably, any end face of the roller 100 is detachably connected to the main body of the roller 100 to facilitate the replacement of the tape roll 400.

[0051] Preferably, the ink adhesion tester can be used with the conveyor 900 in the prior art, and the conveyor 900 is provided with a clamping mechanism 901 for clamping and fixing the sheet material;

[0052] Preferably, the conveyor 900 can be a roller conveyor 900 or a belt conveyor 900, which conveys the sheet material to the area below the roller 100.

[0053] Preferably, the clamping mechanism 901 can be a cylinder set on both sides of the conveyor 900. The plate can be moved between the two cylinders and clamped and fixed by the two cylinders. During the test, the plate is clamped by the clamping mechanism 901 to prevent the plate from sticking and moving synchronously with the roller 100. It also facilitates the separation of the roller 100 from the plate after the test is completed.
