Description

Technical Field

[0001] This invention relates to the field of hot stamping material testing technology, and in particular to a digital holographic hot stamping material testing device. Background Technology

[0002] When screen printing holographic hot stamping anti-counterfeiting labels, the viscosity of the ink increases due to the volatility of ethyl acetate in the ink material. Viscosity directly affects the ink's ability to pass through the screen mesh. If the viscosity is too high, the ink will have difficulty filling the mesh, resulting in incomplete patterns. Therefore, it is necessary to regularly detect the viscosity during the screen printing process. Summary of the Invention

[0003] This invention proposes a digital holographic hot stamping material inspection device to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A digital holographic hot stamping material inspection device, including a screen, and further comprising:

[0006] The squeegee printing mechanism is installed inside the screen and includes two squeegees. The two squeegees are fitted on the inner wall of the screen, and the two sides of the squeegees are in contact with the inner wall of the screen.

[0007] An ink viscosity testing mechanism, which is connected to a scraping printing mechanism, includes a rubber belt, with vertical rods fixed at both ends of the rubber belt, a tension sensor fixed at the top of the vertical rods, and a horizontal plate fixed at the top of the two tension sensors.

[0008] A layered ink-retention mechanism, which is connected to a scraping printing mechanism, includes two layered frames. A partition is fitted inside one side of each layered frame, and a magnet is fixed to one side of each partition.

[0009] A viscosity homogenizing mechanism, which is connected to a scraping printing mechanism, includes a shaft fan, both ends of which are fixed with wheels.

[0010] Furthermore, the scraping printing mechanism also includes a second connecting frame fixed to the top of the two scrapers, a first connecting frame fixed to the top of the second connecting frame, and a movable structure connected to the top of the first connecting frame, which drives the first connecting frame, the second connecting frame, and the two scrapers to move.

[0011] A material tube is fixed to the top of the second connecting frame, and an ink feeder and a solvent feeder are connected to the outside of the material tube.

[0012] Furthermore, the ink viscosity detection mechanism also includes a motor fixed to the top of the connecting frame two, and a reciprocating screw is fixed to the output end of the motor;

[0013] The reciprocating screw is threaded inside the horizontal plate;

[0014] Two guide rods are fixed to the top of the second connecting frame, and the two guide rods are sleeved inside the horizontal plate.

[0015] Furthermore, the layered ink-storing mechanism also includes multiple springs fixed to the opposite side of the two scrapers;

[0016] Two tiered racks are respectively fitted inside the two scrapers;

[0017] One end of the spring is fixedly connected to the inner wall of the shelf;

[0018] The two partitions are respectively fitted inside the two scrapers;

[0019] Limiting plates are fixed on opposite sides of both partitions.

[0020] Furthermore, the layered ink-sealable mechanism also includes electromagnets fixed on opposite sides of the two scrapers, and the electromagnets are attracted to the layering frame;

[0021] Push plates are fixed to the inner walls of both sides of the wire mesh, and a second magnet is fixed to one side of the push plate. The first magnet and the second magnet are magnetically attracted to each other.

[0022] Furthermore, the viscosity homogenizing mechanism also includes two mounting plates fixed between the two scrapers, and the shaft fan is rotatably connected to the two mounting plates;

[0023] The bottom of the wheel contacts the bottom inner wall of the wire mesh.

[0024] Furthermore, a controller is fixed to one side of the connecting frame, and the controller is electrically connected to the motor, electromagnet, tension sensor, ink feeder and solvent feeder.

[0025] Compared with existing technologies, the beneficial effects of this invention are:

[0026] 1. This invention detects the viscosity of ink by installing an ink viscosity detection mechanism to pull a rubber band located inside the ink to obtain the resistance to its movement;

[0027] 2. This invention separates the ink to be tested into multiple layers by installing a layered ink-settling mechanism. It utilizes the laminar flow characteristics to make the liquid flow in layers, reducing turbulence and allowing the ink at the detection location to quickly settle down. This avoids the liquid flow affecting the accuracy of the viscosity data. After the ink has settled, the partition is removed, increasing the movement space of the rubber belt, thereby expanding the detection area and improving the detection accuracy.

[0028] 3. This invention uses a viscosity uniformity mechanism to ensure that the viscosity of the material is consistent at the top and bottom. Only the viscosity data of a certain section needs to be detected to calculate the viscosity value of the entire ink. The consistency of viscosity provides a reliable guarantee for the accuracy of the detection data. In addition, during the filling process of the screen printing material holes, the rotation of the shaft provides a downward thrust for the ink, allowing the ink to fill quickly and avoiding insufficient filling.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Example: Refer to Figures 1-5 A digital holographic hot stamping material inspection device, comprising a screen 1, and further comprising:

[0039] The scraping printing mechanism 2 is installed inside the screen 1 and includes two scrapers 23. The two scrapers 23 are sleeved on the inner wall of the screen 1, and the two sides of the scrapers 23 are in contact with the inner wall of the screen 1.

[0040] The ink viscosity detection mechanism 3 is connected to the scraping printing mechanism 2. It includes a rubber belt 37, with vertical rods 36 fixed at both ends of the rubber belt 37. A tension sensor 35 is fixed at the top of the vertical rod 36. A horizontal plate 34 is fixed at the top of the two tension sensors 35. A liquid level sensor is fixed at the bottom of the horizontal plate 34 to obtain the ink liquid level in real time.

[0041] The layered ink-retention mechanism 4 is connected to the scraping printing mechanism 2 and includes two layered frames 41. A partition 43 is fitted inside one side of the layered frame 41, and a magnet 44 is fixed on one side of the partition 43.

[0042] The viscosity uniformity mechanism 5 is connected to the scraping printing mechanism 2 and includes a shaft fan 52, with wheels 53 fixed at both ends of the shaft fan 52.

[0043] The scraping printing mechanism 2 also includes a connecting frame 22 fixed to the top of the two scrapers 23. A connecting frame 21 is fixed to the top of the connecting frame 22. A movable structure is connected to the top of the connecting frame 21. The movable structure drives the connecting frame 21, the connecting frame 22 and the two scrapers 23 to move.

[0044] The top of the connecting frame 22 is fixed with a feed tube 24, which is connected to an ink feeder and a solvent feeder.

[0045] The ink viscosity testing mechanism 3 also includes a motor 31 fixed on the top of the connecting frame 22, and a reciprocating screw 32 is fixed at the output end of the motor 31;

[0046] The reciprocating screw 32 is threaded inside the horizontal plate 34;

[0047] Two guide rods 33 are fixed to the top of the connecting frame 22, and the two guide rods 33 are sleeved inside the horizontal plate 34.

[0048] Then, the motor 31 is started to drive the reciprocating screw 32 to rotate, causing the horizontal plate 34 to move the tension sensor 35, the vertical rod 36 and the rubber belt 37 upward. When the rubber belt 37 moves upward, the ink will generate resistance to it. The tension sensor 35 acquires the resistance data and transmits it to the controller. After acquiring the resistance data, the controller makes a judgment. When the viscosity is too high, it controls the solvent supply to add the specified solvent to the ink through the feed pipe 24 according to the viscosity data to ensure the viscosity of the ink.

[0049] The layered ink-settling mechanism 4 also includes multiple springs 42 fixed to the opposite side of the two scrapers 23;

[0050] Two layered racks 41 are respectively fitted inside the two scrapers 23;

[0051] One end of the spring 42 is fixedly connected to the inner wall of the layered shelf 41;

[0052] Two partitions 43 are respectively fitted inside the two scrapers 23;

[0053] Limiting plates 45 are fixed on the opposite sides of the two partitions 43.

[0054] The layered ink-settling mechanism 4 also includes electromagnets fixed to the opposite side of the two scrapers 23, and the electromagnets are attracted to the layering frame 41.

[0055] Push plates 46 are fixed on both inner walls of the wire mesh 1. A magnet 47 is fixed on one side of the push plate 46. Magnet 44 and magnet 47 are magnetically attracted to each other.

[0056] When the two scrapers 23 move close to the edge of the screen 1, the layering frame 41, magnet 1 44 and magnet 2 47 on one side and the push plate 46 on the other side come into contact. Magnet 1 44 and magnet 2 47 are magnetically attracted. If they continue to move, the layering frame 41 will compress the spring 42 to cover the ink to be detected and the rubber strip 37 between the two scrapers 23. The layering frame 41 and the partition 43 will separate the ink to be detected into multiple layers. The laminar flow characteristics will be used to make the liquid flow in layers, reduce turbulence, and make the ink at the detection position quickly stop, so as to avoid the liquid flow affecting the accuracy of the viscosity data.

[0057] The electromagnet corresponding to the drive layering frame 41 attracts the layering frame 41, maintaining the compressed state of the spring 42. Subsequently, the moving mechanism drives the scraper 23 and other structures to move in the opposite direction. Due to the magnetic attraction between magnet 44 and magnet 47, the partition 43 is slowly pulled out and limited by the limiting plate 45. Continuous movement causes magnets 44 and 47 to disengage from the magnetic attraction, and the partition 43 is removed after the ink has settled. This increases the movement space of the rubber belt 37, thereby expanding the detection area and improving detection accuracy.

[0058] The viscosity homogenization mechanism 5 also includes two mounting plates 51 fixed between the two scrapers 23, and the shaft fan 52 is rotatably connected to the two mounting plates 51.

[0059] The bottom of wheel 53 contacts the bottom inner wall of wire mesh 1.

[0060] As the scraper 23 moves, the wheel 53 moves synchronously and rubs against the bottom of the screen 1, driving the shaft fan 52 to rotate, ensuring thorough mixing of the ink at the bottom and top. This design ensures that the viscosity of the material is highly consistent between the top and bottom, allowing the viscosity of the entire ink to be calculated by testing only a certain section. This viscosity consistency provides a reliable guarantee for the accuracy of the test data. Furthermore, during the filling process of the screen mesh orifices, the rotation of the shaft fan 52 provides thrust for the ink, enabling it to fill quickly and preventing insufficient filling.

[0061] A controller is fixed on one side of the connecting frame 21. The controller is electrically connected to the motor 31, electromagnet, tension sensor 35, ink feeder and solvent feeder.

[0062] Working principle:

[0063] The moving structure drives the connecting frame 1 21, connecting frame 22, scraper 23, ink viscosity detection mechanism 3, layered ink-static mechanism 4 and viscosity uniform mechanism 5 to move. The two scrapers 23 push the ink material located in the middle to move. During the movement, the ink material automatically fills into the material hole of the screen and is printed on the paper below the screen (the matching of paper and screen is common knowledge, so it is not shown).

[0064] Because ethyl acetate in the ink material is volatile, its evaporation increases the ink's viscosity, which directly affects its ability to pass through the screen mesh. Excessive viscosity can cause the ink to fail to fill the mesh, resulting in incomplete patterns. Therefore, viscosity needs to be checked periodically during the screen printing process.

[0065] When the two scrapers 23 move close to the edge of the screen 1, the layering frame 41, magnet 1 44 and magnet 2 47 on one side and the push plate 46 on the other side come into contact. Magnet 1 44 and magnet 2 47 are magnetically attracted. If they continue to move, the layering frame 41 will compress the spring 42 to cover the ink to be detected and the rubber strip 37 between the two scrapers 23. The layering frame 41 and the partition 43 will separate the ink to be detected into multiple layers. The laminar flow characteristics will be used to make the liquid flow in layers, reduce turbulence, and make the ink at the detection position quickly stop, so as to avoid the liquid flow affecting the accuracy of the viscosity data.

[0066] The electromagnet corresponding to the drive layering frame 41 attracts the layering frame 41, maintaining the compressed state of the spring 42. Subsequently, the moving mechanism drives the scraper 23 and other structures to move in the opposite direction. Due to the magnetic attraction between magnet 44 and magnet 47, the partition 43 is slowly pulled out and limited by the limiting plate 45. Continuous movement causes magnet 44 and magnet 47 to disengage from the magnetic attraction, and the partition 43 is removed after the ink has settled. This increases the movement space of the rubber belt 37, thereby expanding the detection area and improving detection accuracy.

[0067] Then, the motor 31 is started to drive the reciprocating screw 32 to rotate, causing the horizontal plate 34 to move the tension sensor 35, the vertical rod 36 and the rubber belt 37 upward. When the rubber belt 37 moves upward, the ink will generate resistance to it. The tension sensor 35 acquires the resistance data and transmits it to the controller. After acquiring the resistance data, the controller makes a judgment. When the viscosity is too high, it controls the solvent supply to add the specified solvent to the ink through the feed pipe 24 according to the viscosity data to ensure the viscosity of the ink.

[0068] As the scraper 23 moves, the wheel 53 moves synchronously and rubs against the bottom of the screen 1, driving the shaft fan 52 to rotate, ensuring thorough mixing of the ink at the bottom and top. This design ensures that the viscosity of the material is highly consistent between the top and bottom, allowing the viscosity of the entire ink to be calculated by testing only a certain section. This viscosity consistency provides a reliable guarantee for the accuracy of the test data. Furthermore, during the filling process of the screen mesh orifices, the rotation of the shaft fan 52 provides thrust for the ink, enabling it to fill quickly and preventing insufficient filling.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
