Description

Technical Field

[0001] The invention relates to the technical field of printing, in particular to a wear-resistance detector for ink printing on the surface of a corrugated board. Background Art

[0002] In the production and processing of corrugated cardboard, the quality of surface ink printing is one of the important indicators for evaluating the durability and aesthetics of cardboard. In order to ensure that the ink printing on the surface of corrugated cardboard has good wear resistance, it is necessary to conduct a wear resistance test.

[0003] When the existing printing plate is tested for wear resistance, it is necessary to rub the printing plate printed with ink through a friction plate, and the wear resistance of the printing plate is tested through uninterrupted friction. However, this friction method only uses the friction plate for friction, and the friction efficiency is low. In addition, during the long-term friction process, a large amount of dust and debris will accumulate at the bottom and around the friction plate. This dust will not only affect the contact state between the friction plate and the printing plate, causing changes in friction force, but also interfere with signal acquisition and analysis during the friction process, thereby further affecting the accuracy of wear resistance detection. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a corrugated board surface ink printing wear resistance detector, comprising an equipment main body and a corrugated paper assembly, wherein the corrugated paper assembly printed with ink is arranged at the top of the equipment main body; a grinding mechanism is arranged on the surface of the equipment main body close to the corrugated paper assembly, and the grinding mechanism includes a pushing plate installed on the top of the equipment main body; a friction assembly is arranged inside the pushing plate close to the corrugated paper assembly, and the friction assembly includes a long plate installed inside the pushing plate, a reinforcing plate is clamped inside the long plate, a top plate is installed in the middle of the reinforcing plate, and a plurality of cylinders filled with cooling water are rotatably installed on the bottom end of the top plate, and limit plates are installed on both sides of the cylinders, and friction plates are installed on the surface of the cylinder close to the corrugated paper assembly; grayscale detectors are arranged at both ends of the pushing plate.

[0007] As a preferred technical solution of the present invention, an alternating mechanism is arranged inside the pushing disk, and the alternating mechanism includes a driving motor installed inside the pushing disk, and a gear is installed on the output shaft of the driving motor. The friction components are arranged in two groups in an alternating manner, and racks are installed on the tops of the two groups of friction components, and the racks are meshed with the gears.

[0008] As a preferred technical solution of the present invention, an electric push rod is installed inside the device body, and an assembly splint is installed at the output end of the electric push rod, and one end of the assembly splint is connected to the push plate; a stabilizing mechanism is arranged inside the device body, and the stabilizing mechanism includes a fixed rod, a slider is slidably installed on the outer surface of the fixed rod, a sliding groove is provided at the top of the fixed rod, a pulley is installed inside the slider near the sliding groove, and the pulley slides inside the sliding groove.

[0010] As a preferred technical solution of the present invention, a plurality of viscoelastic dampers are arranged between the pushing plate and the assembling clamping plate.

[0011] As a preferred technical solution of the present invention, a limiting mechanism is provided at the top of the equipment body, and the limiting mechanism includes a base plate installed at the top of the equipment body, and the corrugated paper assembly is arranged at the top of the base plate.

[0015] 3. The electric push rod and assembly clamp set inside the main body of the equipment in the present invention can adjust the height and position of the friction component as needed to ensure that the friction between it and the corrugated cardboard is moderate, and the fixed rod, slider and pulley components in the stabilizing mechanism together constitute a stable support and adjustment system. This not only ensures the stability of the push plate and the friction component during the test, but also reduces the friction and wear between the components through the lubrication of the oil inlet barrel and the oil outlet pipe, thereby increasing the service life of the equipment.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1-10 The embodiment of the present application provides a corrugated cardboard surface ink printing wear resistance detector, which includes a device body 1 and a corrugated paper component 4. The corrugated paper component 4 printed with ink is arranged on the top of the device body 1.

[0030] The ink on the surface of the corrugated paper component 4 is evenly attached to the surface of the paperboard.

[0031] In the technical solution of the embodiment of the present application, a grinding mechanism 3 is provided on the surface of the device body 1 close to the corrugated paper assembly 4 , and the grinding mechanism 3 includes a pushing plate 33 installed on the top of the device body 1 .

[0032] The friction plate 3510 is driven to move by the push disk 33 to rub the ink on the surface of the printing plate, so as to detect the wear resistance of the ink on the surface of the corrugated board.

[0033] Specifically, a friction assembly 35 is provided inside the pushing plate 33 near the corrugated paper component 4, and the friction assembly 35 includes a long plate 351 installed inside the pushing plate 33, and a reinforcing plate 355 is clamped inside the long plate 351, and a top plate 356 is installed in the middle of the reinforcing plate 355, and a plurality of cylinders 359 filled with cooling water are rotatably installed at the bottom end of the top plate 356, and limiting plates 358 are installed on both sides of the cylinder 359, and a friction plate 3510 is installed on the surface of the cylinder 359 close to the corrugated paper component 4.

[0034] When the push plate 33 drives the cylinder 359 to move, the friction plate 3510 on the surface of the cylinder 359 rubs the corrugated cardboard, and the side-by-side design of multiple cylinders 359 can greatly improve the detection efficiency. At the same time, the cylinder 359 rotates at the bottom end of the top plate 356, so that the cylinder 359 can swing left and right to drive the left and right sides of the friction plate 3510 to perform alternating friction, thereby improving the service life of the friction plate 3510. In long-term or high-intensity friction tests, the friction plate 3510 may be thermally deformed due to frictional heat. Cooling the friction plate 3510 with cooling water can ensure that the friction plate 3510 maintains a relatively stable temperature during the test, which helps to reduce the test error caused by temperature changes and improve the accuracy and reliability of the test.

[0035] In some embodiments, grayscale detectors 38 are disposed at both ends of the pushing plate 33 .

[0036] The light emitting diode in the grayscale detector 38 emits light of a certain intensity, which is irradiated onto the printing plate to be detected, and the ink on the printing plate will reflect part of the light; the photosensitive receiving tube receives the reflected light and converts it into an electrical signal; the electrical signal output by the photosensitive receiving tube is processed by the circuit to obtain a grayscale value, which is a relative quantity used to indicate the color depth or the intensity of the reflected light at a certain point on the printing plate; and the wear resistance of the printed paperboard is evaluated by detecting the grayscale value of the ink on the surface of the printed paperboard.

[0037] In some embodiments, the interior of the long plate 351 is electrically connected to the electrostatic generator 352 through a built-in power supply, and an electrostatic adsorption magnetic plate 353 is installed on the inner wall of the long plate 351 close to the friction plate 3510 , and the electrostatic generator 352 is electrically connected to the electrostatic adsorption magnetic plate 353 .

[0038] Among them, the electrostatic generator 352 is electrically connected to the electrostatic adsorption magnetic plate 353 through an external power supply. When the electrostatic field generated by the electrostatic generator 352 acts on the electrostatic adsorption magnetic plate 353, the surface of the electrostatic adsorption magnetic plate 353 will carry positive and negative charges. Under the action of the electrostatic field, these charges form a certain electric field distribution, thereby generating electrical adsorption ability. Under the action of the electric field force, the charged dust particles gradually approach the electrostatic adsorption magnetic plate 353 and are finally deposited on its outer surface, thereby reducing the impact of dust on the surface of the friction plate 3510.

[0039] In some embodiments, the cross-section of the electrostatic adsorption magnetic plate 353 is arc-shaped, a collection box 354 is installed inside the long plate 351 located at the bottom of the electrostatic adsorption magnetic plate 353, and a plurality of through grooves 357 are opened on the surface of the top plate 356, and the cross-section of the through grooves 357 is conical.

[0040] When the arc-shaped electrostatic adsorption magnetic plate 353 is used, the dust on its surface will be affected by gravity, causing the dust to slide to the bottom of the arc and be collected by the collection box 354, which is convenient for dust management. At the same time, the conical through groove 357 is provided to facilitate dust suction and collection, and the conical hole can also reduce dust extraction and secondary pollution.

[0041] In some embodiments, an alternating mechanism 36 is disposed inside the pushing disk 33, and the alternating mechanism 36 includes a driving motor 361 installed inside the pushing disk 33, and a gear 363 is installed on the output shaft of the driving motor 361. Two groups of friction components 35 are staggered, and racks 362 are installed at the tops of the two groups of friction components 35, and the racks 362 and the gears 363 are meshed.

[0042] Among them, the gear 363 is driven to rotate by the driving motor 361, and the gear 363 drives the rack 362 to move. Through the up and down movement of the two racks 362, the two groups of friction components 35 can intermittently rub the corrugated paper component 4. The intermittent friction can reduce the continuous contact and friction between the friction plate 3510 and the ink plate, thereby reducing the degree of wear of the friction plate 3510 and extending its service life. It can also appropriately shorten the test time and improve the test efficiency while ensuring the test quality.

[0043] In some embodiments, an electric push rod 31 is installed inside the device body 1 , an assembly clamp 32 is installed at the output end of the electric push rod 31 , and one end of the assembly clamp 32 is connected to the pushing disk 33 .

[0044] Among them, by providing a detachable assembly clamp 32, the push plate 33 can be made more stable, and the spacing, pressure and other coefficients of the push plate 33 can be easily adjusted, thereby improving the accuracy of the wear resistance detection of inks of different printing plates.

[0045] In some embodiments, a stabilizing mechanism 37 is provided inside the device body 1, and the stabilizing mechanism 37 includes a fixing rod 372, a slider 375 is slidably installed on the outer surface of the fixing rod 372, a sliding groove 374 is provided at the top of the fixing rod 372, and a pulley 376 is installed inside the slider 375 near the sliding groove 374, and the pulley 376 slides inside the sliding groove 374.

[0046] When the friction plate 3510 is driven to move by the electric push rod 31, the fixed rod 372 is provided so that the slider 375 at the output end of the electric push rod 31 is stably slidably installed on the surface of the fixed rod 372, thereby supporting the push plate 33. At the same time, a pulley 376 is slidably installed inside the slide groove 374 at the top of the fixed rod 372, thereby increasing the sliding effect of the entire friction plate 3510 and improving the detection accuracy.

[0047] In some embodiments, an oil inlet barrel 371 is installed inside the device body 1, the oil outlet end of the oil inlet barrel 371 is connected and installed in the interior of the slide groove 374, and the free end of the fixing rod 372 is connected and installed with an oil outlet pipe 373.

[0048] Among them, by adding lubricating oil inside the slide groove 374, the pulley 376 adheres to the inside of the slide groove 374 through the lubricating oil, and the lubricating oil can form a lubricating film between the pulley 376 and the slide groove 374, effectively reducing the friction resistance between the two, which can not only make the pulley 376 slide more smoothly in the slide groove 374, but also reduce the wear of the pulley 376 and the slide groove 374, and extend their service life; during the sliding process of the pulley 376 and the slide groove 374, a certain amount of heat will be generated due to friction, and the lubricating oil can play a certain heat dissipation role, take away the generated heat in time, and maintain the normal operating temperature of the equipment.

[0049] In some embodiments, a plurality of viscoelastic dampers 34 are disposed between the pushing plate 33 and the assembling clamping plate 32 .

[0050] Among them, the viscoelastic damper 34 has a high damping ratio and a low damping stiffness, and can effectively absorb and dissipate vibration energy. In the ink wear resistance test, the friction between the friction plate 3510 and the printing ink plate will generate a certain amount of vibration and energy. The viscoelastic damper 34 can convert this energy into heat energy and dissipate it, thereby reducing the vibration response of the structure and protecting the test equipment and the ink plate from damage.

[0051] In some embodiments, a limiting mechanism 2 is provided at the top of the device body 1, and the limiting mechanism 2 includes a base plate 21 installed at the top of the device body 1, and the corrugated paper component 4 is arranged at the top of the base plate 21. Two support frames 23 are installed on the top of the device body 1 near the corrugated paper component 4, and a pressure plate 22 is installed at the top of the support frame 23 through a screw, and the pressure plate 22 is located at the top of the corrugated paper component 4.

[0052] The corrugated paper assembly 4 placed on the top of the bottom plate 21 can be limited by the pressing plate 22, thereby ensuring the stability of the continuous friction of the friction plate 3510.

[0053] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
