Description

Technical Field

[0001] This utility model relates to the technical field of ink homogenization devices, and more specifically to an ink homogenization device based on screen printing. Background Technology

[0002] Screen printing involves stretching a wire mesh (made of silk, nylon, polyester fiber, or stainless steel) onto a frame, fixing it taut. A screen printing plate is created using manual etching or photochemical methods, ensuring the mesh openings in the image areas are open while those in the non-image areas are blocked. During printing, ink is placed in the frame, and a rubber squeegee is used to apply pressure and move the ink through the mesh openings in the image areas onto the substrate, creating an image identical to the original artwork.

[0003] For example, the prior art disclosure number CN221605377U describes an ink homogenization device based on screen printing. This utility model is equipped with a scraping mechanism, in which a horizontal drive component drives the scraper to move laterally, thereby squeezing the ink from the mesh of the image area onto the screen printing substrate. In addition, a lifting component drives the scraper to approach the screen printing plate and ensures that the scraper can apply constant pressure to the ink, thereby improving the printing quality of screen printing.

[0004] However, the existing technology described above still has the following problems in use: when the vertical squeegee pushes the ink, the ink will accumulate rapidly in the direction of the squeegee's movement, resulting in uneven ink spreading and affecting the printing effect. Based on this, the present invention provides an ink homogenizing device for screen printing with good homogenization effect. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides an ink homogenization device based on screen printing. A lifting mechanism automatically raises and lowers the screen printing plate, facilitating rapid material changes and thus improving printing efficiency. Furthermore, a micro-motor drives a rotating rod to rotate the squeegee, automatically adjusting its tilt angle. The tilted squeegee homogenizes the ink, allowing it to gradually spread along the tilted squeegee direction, promoting uniform ink distribution on the screen printing plate and improving printing quality. This addresses the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ink homogenization device based on screen printing, comprising a base, a pedestal for placing paper fixedly mounted on the top of the base, a screen printing plate mounted on the top of the base, the screen printing plate being mounted on the base via a lifting mechanism, a scraper being provided inside the screen printing plate, a driving mechanism being provided on the scraper, the driving mechanism comprising a long plate, a rotating rod being rotatably mounted inside the long plate, the scraper being fixedly sleeved on the rotating rod, a micro motor being fixedly mounted at the rear end of the long plate, the front end of the output shaft of the micro motor passing through the long plate and fixed to the rear end of the rotating rod, and the long plate being mounted on the base via a moving mechanism.

[0007] In a preferred embodiment, the lifting mechanism includes a top plate fixed to the top of the base, and electric push rods are fixed on both sides of the top plate. The bottom end of the output shaft of the electric push rod is fixed to the top of the screen printing plate. The screen printing plate is lifted and lowered by the electric push rod, which can improve the efficiency of loading and unloading, and thus improve the printing efficiency.

[0008] In a preferred embodiment, the moving mechanism includes a moving frame, with an electric push rod two fixedly passing through the center of the top of the moving frame. The bottom end of the piston rod of the electric push rod two is fixed to the top of the long plate. Linear modules are fixedly provided on both sides of the bottom end of the moving frame. The two linear modules are fixedly embedded in the top of the base. The linear modules simultaneously drive the moving frame to move horizontally, thereby achieving automatic ink homogenization and improving printing efficiency.

[0009] In a preferred embodiment, a rectangular through slot is provided on the top of the top plate, and the top end of the electric push rod 2 extends through the rectangular through slot, so that the electric push rod 2 can move together with the moving frame, avoiding the top plate from obstructing the movement of the electric push rod 2.

[0010] In a preferred embodiment, limiting rods are fixedly provided on both sides of the top of the long plate, and limiting holes are opened on both sides of the top of the movable frame. The top of the limiting rods passes through the limiting holes. When the long plate moves up and down, the two limiting rods move in the two limiting holes respectively, thereby improving the stability of the long plate lifting and lowering.

[0011] In a preferred embodiment, the top of the base is provided with a placement groove, and a rectangular slot connected to the placement groove is provided on one side of the base. The rectangular slot facilitates workers to quickly pick up and replace the paper, thereby improving the efficiency of loading and unloading.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention uses a lifting mechanism to automatically raise and lower the screen printing plate, facilitating quick material changes and thus improving printing efficiency. Furthermore, a micro-motor drives a rotating rod to rotate the squeegee, automatically adjusting its tilt angle. The tilted squeegee homogenizes the ink, allowing it to spread gradually along the squeegee's direction, promoting even ink distribution on the screen printing plate and improving printing quality.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides an ink homogenization device based on screen printing, including a base 1. A base 2 for placing paper is fixedly provided on the top of the base 1. A screen printing plate 3 is provided on the top of the base 2. The screen printing plate 3 is installed on the base 1 through a lifting mechanism 4. Specifically, the lifting mechanism 4 includes a top plate 41 fixed to the top of the base 1. Electric push rods 42 are fixed on both sides of the top plate 41. The bottom end of the output shaft of the electric push rod 42 is fixed to the top of the screen printing plate 3.

[0025] The screen printing plate 3 has a squeegee 5 inside, and a driving mechanism 6 is provided on the squeegee 5. The driving mechanism 6 includes a long plate 61, and a rotating rod 62 is rotatably provided inside the long plate 61. The squeegee 5 is fixedly sleeved on the rotating rod 62. A micro motor 63 is fixedly provided at the rear end of the long plate 61. The front end of the output shaft of the micro motor 63 passes through the long plate 61 and is fixed to the rear end of the rotating rod 62. The long plate 61 is installed on the base 1 through a moving mechanism 7. The moving mechanism 7 can realize the automatic translation of the long plate 61 and the squeegee 5.

[0026] In actual use, the operator first places the paper to be printed in the placement slot 11 inside the base 2. Then, the electric push rod 42 extends to drive the screen printing plate 3 to move down and press it against the base 2 and the top of the paper. Then, printing ink is poured onto the screen printing plate 3. After that, the moving mechanism 7 on the base 1 drives the long plate 61 to move left and right. Before that, the micro motor 63 drives the rotating rod 62 to rotate the squeegee 5 so that the squeegee 5 is at a certain angle (e.g., 70 degrees). Then, the ink on the screen printing plate 3 is scraped evenly. The angle between the inclined squeegee 5 and the surface of the screen printing plate 3 is small, so that the ink flows more smoothly and is closer to the surface of the screen printing plate 3 under the push of the squeegee 5. This prevents the ink from accumulating in front of the squeegee 5, but gradually spreads along the inclined squeegee 5. This is conducive to the even distribution of ink on the screen printing plate 3. The ink is evenly squeezed onto the surface of the paper on the base 2 through the mesh of the screen printing plate, and the graphics are printed on the paper surface, resulting in a good printing effect.

[0027] Refer to the instruction manual appendix Figures 1-5 The moving mechanism 7 includes a moving frame 71, with an electric push rod 72 fixedly passing through the center of the top of the moving frame 71. The bottom end of the piston rod of the electric push rod 72 is fixed to the top of the long plate 61. Linear modules 73 are fixedly provided on both sides of the bottom end of the moving frame 71. Both linear modules 73 are fixedly embedded in the top of the base 1. At the same time, a rectangular through slot 8 is opened on the top of the top plate 41. The top end of the electric push rod 72 passes through the rectangular through slot 8, so that the electric push rod 72 can move together with the moving frame 71.

[0028] Furthermore, limiting rods 9 are fixed on both sides of the top of the long plate 61, and limiting holes 10 are opened on both sides of the top of the moving frame 71. The top of the limiting rod 9 passes through the limiting hole 10. When the long plate 61 moves up and down, the two limiting rods 9 move in the two limiting holes 10 respectively, thereby improving the stability of the lifting of the long plate 61.

[0029] like Figure 5 As shown, a placement groove 11 is provided on the top of the base 2, and a rectangular slot 12 connected to the placement groove 11 is provided on one side of the base 2. The rectangular slot 12 is provided to facilitate workers to quickly pick up and replace the paper, thereby improving the efficiency of loading and unloading.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
