Description

Technical Field

[0001] The utility model relates to the field of ink production, in particular to an ink wear resistance detection device. Background Art

[0002] Ink is an important material for printing, and it shows patterns and texts on a printing substrate through printing, spraying or other means.

[0003] After the ink is produced, it is usually applied to printing substrates such as films and fabrics for wear resistance detection. In the prior art, an ink wear resistance detection device is usually used to detect the wear resistance of the ink. The ink wear resistance detection device fixes the printing substrate coated with ink on a workbench and uses a friction member to reciprocally rub the ink layer of the printing substrate, thereby detecting the wear resistance of the ink. However, the ink wear resistance detection device in the prior art usually rubs the printing substrate on a flat surface and cannot rub the printing substrate on a curved surface. During transportation and packaging, the ink layer of the printing substrate cannot always remain on the same plane. Due to friction with external items, the ink-coated printing substrate that passes the flat surface friction test may be worn, which not only affects the use but also the commercial reputation of the manufacturer.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0025] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0026] Referring to Figures 1 to 5 , the ink wear resistance detection device according to a preferred embodiment of the present utility model will be described in detail below. The ink wear resistance detection device is used to detect the wear resistance of the ink layer of the printing substrate 90.

[0027] The ink wear resistance detection device includes a device main body 10, at least a pair of fixing components 20, a driving and displacing component 30, and at least one friction component 40.

[0028] The device body 10 includes a mounting table 11, a moving seat 12, and a mounting frame 13. The moving seat 12 is movably mounted above the mounting table 11, and the mounting frame 13 is fixed to the mounting table 11 and the mounting frame 13 is higher than the upper surface of the moving seat 12. The upper surface of the moving seat 12 is set to be arc-shaped.

[0029] Each pair of the fixing components 20 is respectively mounted at both ends of the arc-shaped surface of the moving seat 12, and each pair of the fixing components 20 can respectively press both ends of a printing substrate 90 to press the printing substrate 90 onto the surface of the moving seat 12 to form a curved surface, so as to simulate the environment in the case of transportation or packaging.

[0030] The displacement component 30 is mounted on the mounting table 11, and the displacement component 30 is located below the moving seat 12. The displacement component 30 can drive the moving seat 12 to move in the horizontal direction.

[0031] By way of example, the displacement component 30 is implemented as a telescopic cylinder.

[0032] The friction component 40 is rotatably mounted on the mounting frame 13, and each friction component 40 can friction with the ink layer of the printing substrate 90 fixed on the moving seat 12 and moving synchronously with the moving seat 12. When the displacement component 30 drives the moving seat 12 to move, the friction component 40 can friction relative to the moving seat 12 from one end of the printing substrate 90 fixed by the fixing component 20 to the other end of the printing substrate 90 fixed by the fixing component 20, so as to friction the upper surface of the printing substrate 90 to simulate the friction generated in the actual transportation or packaging process, so as to detect the abrasion resistance of the ink applied on the printing substrate 90 subsequently.

[0033] Preferably, the moving base 12 has at least two pairs of mounting portions 121. The two mounting portions 121 of a pair are arranged at intervals relative to each other. Both end portions of the bending plane of the moving base 12 extend upward respectively to form at least one pair of the mounting portions 121. Each fixing assembly 20 includes a fixing body 21 and a fixing driving member 22. Each fixing body 21 is mounted between a pair of the mounting portions 121 of the moving base 12. The fixing driving member 22 is drivingly connected to the fixing body 21 to adjust the distance between the fixing body 21 and the bending plane of the moving base 12. When the distance between the fixing body 21 and the bending plane of the moving base 12 is at its maximum, the end portion of the printing medium 90 can be inserted between the fixing body 21 and the moving base 12. After the end portion of the printing medium 90 is inserted between the fixing body 21 and the moving base 12, the fixing driving member 22 drives the fixing body 21 to reduce the distance between the fixing body 21 and the moving base 12, so that the fixing body 21 presses against the end portion of the printing medium 90 to jointly fix the printing medium 90 with the bending plane of the moving base 12.

[0034] In one embodiment, the fixing driving member 22 is implemented as a pull rod. The fixing body 21 is rotatably mounted on the mounting portion 121. The fixing driving member 22 is rotatably connected to one end portion of the fixing body 21 and can drive the fixing body 21 to rotate. The surface of the fixing body 21 has a protruding portion 211. The minimum distance between the protruding portion 211 and the bending plane of the moving base 12 is less than the thickness of the printing medium 90. The fixing assembly 20 further includes a reset member 23. The reset member 23 is mounted between the moving base 12 and the fixing body 21. Without external force, the fixing body 21 is under the elastic force of the reset member 23, so that the protruding portion 211 always maintains the minimum distance from the bending plane of the moving base 12.

[0035] By way of example, the reset member 23 is implemented as a torsion spring.

[0036] When the operator pulls the fixing driving member 22 to drive the fixing body 21 to rotate by the fixing driving member 22, increasing the distance between the protruding portion 211 and the bending plane of the moving base 12, the reset member 23 undergoes elastic deformation. At the same time, the end portion of the printing medium 90 can be inserted between the fixing body 21 and the moving base 12. Then the operator releases the fixing driving member 22. The fixing body 21 resets under the elastic action of the reset member 23, so that the protruding portion 211 presses against the surface of the end portion of the printing medium 90 and presses the printing medium 90 against the moving base 12, thereby fixing the end portion of the printing medium 90.

[0037] In another embodiment, the fixed driving member 22 is implemented as a cylinder. The fixed main body 21 is slidably mounted on the moving seat 12. The fixed driving member 22 is connected to one end of the fixed main body 21 and can drive the fixed main body 21 to approach or move away from the moving seat 12. When the distance between the fixed main body 21 and the moving seat 12 is greater than the thickness of the printing material 90, the end of the printing material 90 is inserted between the fixed main body 21 and the moving seat 12. Subsequently, the fixed driving member 22 drives the fixed main body 21 to approach the moving seat 12, thereby reducing the distance between the fixed main body 21 and the moving seat 12, so that the fixed main body 21 abuts against the end of the printing material 90 and jointly fixes the end of the printing material 90 with the moving seat 12.

[0038] Preferably, the displacement assembly 30 includes a driving member 31, a rotating disk 32, a driving member 33 and at least one slide rail 34. The driving member 31 is mounted on the mounting table 11. The rotating disk 32 is rotatably mounted on the mounting table 11. The driving member 31 is drivingly connected to the rotating disk 32 to cause the rotating disk 32 to rotate. The slide rail 34 is mounted on the mounting table 11, and the slide rail 34 is parallel to the distribution direction of a pair of the fixed main bodies 21. The moving seat 12 is slidably mounted on the slide rail 34. One end of the driving member 33 is rotatably mounted on the rotating disk 32 and is driven by the rotating disk 32 to rotate periodically. The other end of the driving member 33 is rotatably connected to the moving seat 12. Since the moving seat 12 is slidably mounted on the slide rail 34 and the slide rail 34 is fixed, when one end of the driving member 33 is driven by the rotating disk 32 to rotate periodically, the driving member 33 drives the moving seat 12 to reciprocate along the slide rail 34.

[0039] As an example, the driving member 33 is implemented as a driving rod.

[0040] Preferably, the friction assembly 40 includes a friction main body 41 and a rotating rod 42. The friction main body 41 is fixed to one end of the rotating rod 42. The other end of the rotating rod 42 is rotatably mounted on the mounting frame 13. The friction main body 41 located on the rotating rod 42 can rotate coaxially with the rotating rod 42 to approach or move away from the printing material 90 on the moving seat 12.

[0041] It is worth mentioning that, since the surface of the moving seat 12 is a curved plane, when the friction body 41 rubs against the printing material 90 driven by the moving seat 12, the friction body 41 is pushed by the reciprocating moving seat 12 and affected by its own gravity, causing the rotating rod 42 and the friction body 41 to rotate reciprocally as a whole, so as to adapt to the curved plane of the moving seat 12 and meet the wear resistance detection requirements of the printing material 90 in the curved state.

[0042] Preferably, the friction body 41 has a pressing part 411, and the pressing part 411 is located at one end of the friction body 41 away from the moving seat 12. The pressing part 411 is configured to be able to mount weights, so that the pressure exerted by the friction body 41 on the printing material 90 located on the moving seat 12 can be changed, thereby changing the frictional force between the friction body 41 and the printing material 90, and further more accurately detecting the wear resistance of the ink on the printing material 90.

[0043] Preferably, the ink wear resistance detection device further includes a sticker member 50, and the sticker member 50 can stick the cardboard to the end of the friction body 41 where it rubs against the printing material 90, so as to enhance the friction effect of the friction body 41 and prevent the edges and corners of the friction body 41 from scratching the printing material 90, and at the same time facilitate the operator to replace the cardboard at any time.

[0044] Preferably, the sticker member 50 includes a sticker main body 51, a sliding main body 52 and at least one elastic member 53. The sticker main body 51 includes two pierced edges 511 and two sticker edges 512. The two opposite pierced edges 511 and the two opposite sticker edges 512 are connected to form a frame, and the length of the pierced edge 511 is greater than the length of the end of the friction body 41 for sticking the cardboard. The sliding main body 52 includes two sliding edges 521 and two sliding columns 522. One sliding edge 521 passes through the two pierced edges 511 and can slide along the extending direction of the pierced edge 511. One ends of the two sliding columns 522 are slidably passed through one sticker edge 512 and are spacedly connected to both ends of the sliding edge 521, and the other sliding edge 521 is connected to the other ends of the two sliding columns 522 to form a frame, and the hole size of the frame formed by the sliding main body 52 is smaller than the hole size of the frame of the sticker main body 51 and larger than the size of the end of the friction body 41 for sticking the cardboard.

[0045] The elastic member 53 is installed on the sliding column 522. One end of the elastic member 53 is connected to any one of the two sliding edges 521, and the other end is connected to the sticker edge 512 penetrated by the sliding column 522. When there is no external force, the distance between the sliding edge 521 located between the two sticker edges 512 and the two sticker edges 512 is less than the length of the end of the friction main body 41 with the sticker paper attached. When the sliding main body 52 moves relative to the sticker main body 51 to increase the distance between the sliding edge 521 located between the two sticker edges 512 and any one of the two sticker edges 512, the end of the friction main body 41 with the sticker paper attached can be inserted between the corresponding sliding edge 521 and the corresponding sticker edge 512 and fixed by the two after the external force is removed, so that the end of the friction main body 41 with the sticker paper attached can be flexibly assembled with the sticker member 50.

[0046] It can be understood that the operator can increase the distance between the corresponding sliding edge 521 and one of the sticker edges 512 by sliding the sliding edge 521 located between the two sticker edges 512, so that the distance between the sliding edge 521 located between the two sticker edges 512 and one of the sticker edges 512 is greater than the length of the end of the friction main body 41 with the sticker paper attached. Then, the end of the friction main body 41 with the sticker paper attached can be placed between the sliding edge 521 located between the two sticker edges 512 and the corresponding sticker edge 512, and at the same time, the elastic member 53 undergoes elastic deformation. When the external force is removed, the sliding main body 52 is reset under the elastic force of the elastic member 53, so that the sliding edge 521 located between the two sticker edges 512 and the corresponding sticker edge 512 press the sticker paper against the end surface of the friction main body 41 for friction with the printing substrate 90.

[0047] Preferably, the frames formed by the sticker main body 51 and the sliding main body 52 are both set to be rectangular. The number of the elastic members 53 is implemented as two. The two elastic members 53 are respectively installed on the two sliding columns 522. One end of each elastic member 53 is connected to the sliding edge 521 outside the two sticker edges 512, and the other end is connected to the sticker edge 512 penetrated by the sliding column 522.

[0048] It can be understood that before the operator presses the sliding edge 521 outside the two sticker edges 512, the distance between the sliding edge 521 between the two sticker edges 512 and the sticker edge 512 penetrated by the sliding post 522 is less than the length of the end of the friction body 41 with the cardboard attached; after the operator presses the sliding edge 521 outside the two sticker edges 512, the elastic member 53 is compressed, and the sliding edge 521 between the two sticker edges 512 slides away from the sticker edge 512 penetrated by the sliding post 522, so as to increase the distance between the sliding edge 521 between the two sticker edges 512 and the sticker edge 512 penetrated by the sliding post 522, so as to place the end of the friction body 41 with the cardboard attached for friction against the printing substrate 90 between the sliding edge 521 between the two sticker edges 512 and the sticker edge 512 penetrated by the sliding post 522; after the operator no longer presses the sliding edge 521 outside the two sticker edges 512, the elastic member 53 resumes its original state and thus applies a force to the sliding edge 521 outside the two sticker edges 512, so that the sliding edge 521 between the two sticker edges 512 is reset, thereby pressing the cardboard against the surface of the end of the friction body 41 for friction against the printing substrate 90.

[0049] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments.
