Description

Technical Field

[0001] This utility model relates to the field of ink production technology, and more specifically to a dynamic testing device for ink adhesion. Background Technology

[0002] In the process of printing quality control, ink adhesion testing is one of the important indicators for evaluating printing quality. Currently, the industry-wide commonly used cross-cut adhesion test method uses a specific tool to create orthogonal grid scratches on the sample surface, and then combines this with tape peeling to assess the coating adhesion strength. This method has been incorporated into several international standard systems.

[0003] Traditional implementation methods mainly rely on manual operation, requiring operators to complete steps such as marking, bonding, peeling, and visual judgment in sequence. For example, an ink adhesion testing device proposed in publication number CN218003220U can achieve semi-manual testing. However, this discrete testing mode has efficiency bottlenecks and the risk of human error when dealing with large-scale continuous production of printing materials. Utility Model Content

[0009] The transverse scribing component is configured to reciprocate in a direction perpendicular to the movement of the roll material, intermittently forming transverse scratches on the first surface of the roll material passing between the transverse scribing component and the first support surface, thereby forming multiple 100-square areas on the first surface of the roll material.

[0010] The ink stripping component is configured to strip the ink layer from the surface of the grid area;

[0011] The image acquisition component is configured to acquire an image of the stripped 100-grid region;

The height adjustment component is connected to the support component and is used to control the height of the support frame relative to the first support surface. The drive component is used to control the transverse marking roller to move relative to the support frame in a direction perpendicular to the movement of the roll material, thereby forming vertical marks on the first surface of the roll material.

[0018] Preferably, the support frame includes a pair of connecting plates and a guide rod and a lead screw disposed between the connecting plates. The driving component is connected to the lead screw and is used to drive the lead screw to rotate.

[0031] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0032] Combination Figure 1 As shown, for the ink adhesion test of the ink printed material 100, it is usually necessary to use a tool (cross-cutting tool) to form a manual cross-cutting area 101 on the surface of the ink printed material 100. This manual cross-cutting area 101 is inconsistent for multiple ink printed materials 100, and the subsequent peeling operation also has inconsistent test results. At the same time, it cannot meet the testing requirements of large-volume continuous printing materials.

[0033] Combination Figure 2 As shown, in this application, the test object is designed as a roll 200, which has a middle area 202 and a side area 203. Multiple target areas 201 are set along the length of the roll 200. Each target area 201 is coated with different inks, i.e., different test objects. Each target area 201 is provided with a marking structure 205 to characterize the features of the current test object.

[0034] In an optional embodiment, the marking structure 205 may be a serial number, barcode, or QR code, etc.

[0035] Combination Figure 3 As shown, this utility model proposes a dynamic ink adhesion testing device, including a support component 10 and an unwinding component 20, a tension roller group 30, a vertical scribing component 40, a horizontal scribing component 50, an ink peeling component 60, an image acquisition component 70, and a winding component 80 arranged sequentially along the unwinding direction.

[0036] As mentioned above, the test object in this application is roll material 200. After the roll material 200 is placed on the unwinding component 20, it can pass through the tension roller group 30, the vertical scribing component 40, the horizontal scribing component 50, the ink stripping component 60 and the image acquisition component 70 in sequence, and be wound up by the winding component 80, controlling the unwinding mode and speed.

[0037] Specifically, since the roll 200 must be laterally divided into 100-square areas 204 in a stopped state, the winding component 80 is configured to intermittently wind up the roll 200, including both winding and stopped states.

[0038] The support component 10 has a first support surface on its upper part, which provides support for the roll material 200 to be tested.

[0039] Furthermore, the unwinding component 20 is connected to the support component 10 and is used to place the roll material 200 to be tested. The roll material 200 unwound by the unwinding component 20 is wound around the tension roller group 30 between the vertical grading component 40 and the first support surface, and remains in contact with the first support surface.

[0040] Thus, starting from the position of contact with the vertical gridding member 40, the roll material 200 is attached to the surface of the first support surface, especially the first surface of the roll material 200 (including the surface with ink printing) faces the direction of the vertical gridding member 40, and the second surface (excluding the back side with ink printing) faces the first support surface.

[0041] Furthermore, the vertical scribing member 40 is configured to form vertical scratches on the first surface of the roll 200 passing between the vertical scribing member 40 and the first support surface.

[0042] Optionally, the vertical marking component 40 includes a vertical marking roller, the surface of which is provided with a plurality of equally spaced blades. Thus, when the vertical marking roller contacts the roll material 200, vertical scratches of a predetermined depth are formed on the first surface of the roll material 200. Figure 2 As shown, the width of the vertical marking roller is less than or equal to the width of the middle area 202 to avoid damaging the marking structure 205.

[0043] In an optional embodiment, the vertical marking roller is connected to the support member 10 via a height adjustment device, which can control the height of the vertical marking roller, i.e., control the depth of the markings.

[0044] Furthermore, after vertical scratches are formed on the surface of the roll material 200, horizontal scratches are formed by the horizontal scribbling component 50.

[0045] Combination Figure 3 and Figure 4 As shown, the transverse scribing member 50 is configured to reciprocate in a direction perpendicular to the movement of the roll 200, intermittently forming transverse scratches on the first surface of the roll 200 passing between the transverse scribing member 50 and the first support surface.

[0046] Thus, by superimposing horizontal scratches on the vertical scratches, multiple grid areas 204 are formed on the first surface of the roll material 200.

[0047] It should be understood that the 100-grid area 204 consists of one hundred independent squares formed by multiple horizontal and vertical scratches, each square being 1mm in length and width.

[0048] Combination Figure 4 As shown, the surface of the roll 200 has multiple target areas 201, and the moving frequency of the transverse squaring member 50 is set to match the start and stop frequency of the winding member 80.

[0049] Specifically, whenever the roll material 200 stops, the transverse squaring component 50 squares across one of the target areas 201, forming a 100-square grid area 204 within the target area 201. After the current target area 201 forms the 100-square grid area 204, the winding component 80 starts and continues winding until the next target area 201 reaches the corresponding position of the transverse squaring component 50. At this point, the winding component 80 stops winding, and the transverse squaring component 50 squares across the target area 201 again, forming the 100-square grid area 204 within the target area 201. This process is repeated until a 100-square grid area 204 is formed in each target area 201.

[0050] In an optional embodiment, the transverse scribing component 50 includes a support frame 51, a transverse scribing roller 52, a drive component 53, and a height adjustment component 54. The height adjustment component 54 is connected to the support component 10 and is used to control the height of the support frame 51 relative to the first support surface. The drive component 53 is used to control the transverse scribing roller 52 to move relative to the support frame 51 in a direction perpendicular to the movement of the roll 200, forming vertical scratches on the first surface of the roll 200.

[0051] Thus, the transverse scribing roller 52 includes a first position and a second position. When the transverse scribing roller 52 is in the first position or the second position, the transverse scribing roller 52 does not contact the roll material 200. Only when the transverse scribing roller 52 moves from the first position to the second position or from the second position to the first position does it scrib across the surface of the roll material 200, forming a hundred-grid area 204 on the basis of vertical scribing.

[0052] The drive component 53 is used to control the reciprocating movement of the transverse scribing roller 52 between the first position and the second position.

[0053] The height adjustment component 54 can be a threaded rod. By rotating the threaded rod, the height of the support frame 51 can be controlled, which is beneficial to manually adjust the distance between the transverse crisscross roller 52 and the first support surface according to the thickness of the printed material.

[0054] Specifically, the support frame 51 includes a pair of connecting plates 511 and a guide rod 512 and a lead screw 513 disposed between the connecting plates 511. The driving component 53 is connected to the lead screw 513 and is used to drive the lead screw 513 to rotate. The transverse scribing roller 52 has a slider 521 and a sliding sleeve 522 at both ends of its axial direction, respectively. The sliding sleeve 522 is connected to the lead screw 513, and the slider 521 is slidably connected to the guide rod 512.

[0055] Thus, by controlling the forward and reverse rotation of the lead screw 513, the drive component 53 can drive the transverse scribing roller 52 to move from the first position to the second position or from the second position to the first position.

[0056] Furthermore, the ink stripping component 60 is configured to strip the ink layer from the surface of the grid area 204. The image acquisition component 70 is configured to acquire an image of the stripped grid area 204.

[0057] Thus, by acquiring the image, the number of the target area 201 and the peeled state of the grid area 204 can be obtained. The more severe the damage to the grids in the grid area 204, the worse the adhesion, and vice versa.

[0058] In an optional embodiment, the image acquisition component 70 may be an industrial camera.

[0059] In an optional embodiment, one end of the support member 10 is provided with an arc-shaped plate 11, the surface of the arc-shaped plate 11 forms an arc-shaped second support surface, the roll material 200 is kept in contact with the second support surface, and the image acquisition member 70 is disposed on the outside of the arc-shaped plate 11.

[0060] Furthermore, the winding component 80 is disposed below the first support surface, and a set of pressure rollers 12 is provided between the second support surface and the winding component 80. The pressure rollers 12 are used to detect the step distance of a single movement of the roll material 200. The winding component 80 is set to control the roll material 200 to move a fixed length each time.

[0061] Thus, the distance of a single movement of the roll 200 can be detected by the pressure roller 12. By matching the spacing of a single movement of the roll 200 with the length of the target area 201, a hundred-square area 204 can be formed in each target area 201.

[0062] Combination Figure 3 and Figure 5 As shown, the ink stripping component 60 includes a tape unwinding component 61, a pressing roller 62, a stripping roller 63, and a tape winding component 64. The pressing roller 62 and the stripping roller 63 are in close contact with the first support surface. The tape unwinding component 61 is used to place the tape. The free end of the tape passes through the pressing roller 62 and the stripping roller 63 in sequence and is connected to the tape winding component 64.

[0063] Thus, between the pressure roller 62 and the peeling roller 63, the adhesive surface of the tape adheres to the first surface of the roll 200. That is, when the roll 200 reaches the position of the pressure roller 62, the first surface of the roll 200 begins to adhere to the adhesive surface of the tape; between the pressure roller 62 and the peeling roller 63, the first surface of the roll 200 remains adhered to the adhesive surface of the tape; and when it reaches the position of the peeling roller 63, the first surface of the roll 200 begins to separate from the adhesive surface of the tape. In this way, the adhesion of the 100-grid area 204 can be tested.

[0064] In an optional embodiment, both the press roller 62 and the stripping roller 63 are connected to the support structure 601.

[0065] Specifically, the shaft ends of the pressing roller 62 and the peeling roller 63 are provided with bushings 602, which can slide relative to the support structure 601.

[0066] Among them, a spring 604 is provided below the bushing 602, and an adjusting screw 603 is provided above the bushing 602.

[0067] Thus, by controlling the pressing amount of the adjusting screw 603, a predetermined distance is formed between the surfaces of the pressing roller 62 and the peeling roller 63 and the first support surface. Preferably, the pressing roller 62 and the peeling roller 63 are rubber rollers.

[0068] Furthermore, by controlling the pressing amount of the pressing roller 62 and the peeling roller 63, the tightness between the tape and the surface of the roll material can be controlled.

[0069] In conjunction with the above embodiments, this application employs a roll material stepping conveyor and a transverse scouring roller working in synergy to simultaneously complete high-precision grid scouring during continuous production, avoiding test deviations caused by manual scouring force and angle deviations. At the same time, this application can precisely control the tape bonding pressure and peeling angle, ensuring the standardization of the peeling action and reducing the impact of randomness in human operation on the results. In addition, by combining the image acquisition component to collect images of the peeling area, not only can objective quantitative judgment of test results be achieved, but data traceability and process optimization can also be supported.

[0070] As mentioned above, the overall technical solution not only improves detection efficiency but also significantly enhances the consistency and reliability of test results.

[0071] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
