Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing leveling technology, and in particular to a leveling device for a two-color screen printing machine. Background Technology
[0002] Screen printing refers to the process of creating a screen printing plate with images and text using a photosensitive method. Screen printing consists of five main elements: the screen printing plate, the squeegee, the ink, the printing table, and the substrate. It works by utilizing the basic principle that ink can pass through the mesh openings of the screen printing plate where the image areas are open, but not where. During printing, ink is poured into one end of the screen printing plate, and the squeegee applies pressure to the ink areas while moving at a constant speed towards the other end. As it moves, the ink is forced through the mesh openings of the image areas onto the substrate.
[0003] Chinese Patent No. CN211567262U discloses a leveling device for a two-color screen printing machine, including a screen printing machine body. A slide rod is fixedly connected to the top of the screen printing machine body, and a lifting ring is slidably connected to the surface of the slide rod. A bearing is fixedly connected to the front side of the inner wall of the lifting ring, and a connecting column is fixedly connected to the inner ring of the bearing. A gear is fixedly connected to the back of the connecting column, and a toothed plate meshes with the top of the gear. This utility model solves the problem that existing two-color screen printing machines use multiple screws to fix the leveling printing plate, which is time-consuming and laborious to disassemble and clean, prone to stripping, and inconvenient for replacement. This leveling device for a two-color screen printing machine has the advantages of easy disassembly, easy replacement and cleaning, improving the practicality of the two-color screen printing machine and making it easier for users to use.
[0004] When using existing two-color screen printing machine leveling devices, the operator places the substrate on the screen printing table of the screen printing machine body for printing. However, it is not convenient to level the substrate before printing. If the surface of the substrate is wrinkled or uneven, it will affect the printing effect and cause uneven printing, thus reducing the functionality of the two-color screen printing machine leveling device.

[0023] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0024] Example 1
[0025] like Figure 1 - Figure 3As shown, the present invention proposes a leveling device for a two-color screen printing machine, comprising: a screen printing machine body 1, a mounting assembly, an aluminum frame 3, and a leveling assembly; a leveling plate 4 is connected below the aluminum frame 3, and the mounting assembly is connected to the screen printing machine body 1; the mounting assembly includes a mounting guide rail 2, a fixed bracket 201, a driving component a 202, a moving guide block 203, a fixed plate 204, a connecting bracket 205, an inner side plate 206, a driving component b 207, a moving plate 208, a guide rod 209, a pressure plate 210, and a fixed base plate 2. 11; The mounting rail 2 is connected to one side of the screen printing machine body 1. The mounting rail 2 is connected to the fixed bracket 201. The fixed bracket 201 is connected to the driving component a202. The driving end of the driving component a202 is connected to the moving guide block 203. The moving guide block 203 is connected to the fixed plate 204. The fixed plate 204 is connected to the connecting bracket 205. The driving component b207 is connected to the connecting bracket 205. The driving end of the driving component b207 passes vertically downward through the connecting bracket 205 and is connected to the moving plate 208. The moving plate 208 is connected to the guide... The guide rod 209 has its lower end passing through the fixing plate 204 and fixed to the pressure plate 210. The fixing base plate 211 is connected to the lower surface of the fixing plate 204, and the inner side plate 206 is connected to one side of the fixing base plate 211. The pressure plate 210 is connected above the fixing base plate 211 and is used to clamp and install the aluminum frame 3. The leveling assembly is connected to the screen printing machine body 1. The leveling assembly includes a leveling plate 4, a positioning block 401, a mounting plate 402, a fixing block 403, a connecting rod 404, a splicing rod 405, and a driving component. c406; The mounting plate 402 is in the shape of an inverted U. Positioning blocks 401 are connected to both sides of one end of the flat plate 4. The mounting plate 402 and the fixing blocks 403 are connected one-to-one. The fixing blocks 403 are connected to one end of the mounting plate 402. Connecting rods 404 are connected to one side of the mounting plate 402. Connecting rods 404 are connected to both ends of the splicing rod 405. The driving component c406 is connected to the bottom of the splicing rod 405. The driving component c406 is connected to the mounting base 407. The mounting base 407 is connected to the screen printing machine body 1.The inner wall of the aluminum frame 3 is connected to a screen, on which printed graphics are set. The aluminum frame 3 is moved onto the substrate by the structure of the screen printing machine body 1. Then, the squeegee of the screen printing machine body 1 moves the photosensitive emulsion below the screen through the screen. The squeegee drives the photosensitive emulsion to connect with the screen. The screen printing machine body 1 is driven to move the photosensitive emulsion from one side of the screen to the other side, so as to print the graphics onto the substrate. Before the substrate is extended, the leveling component applies pressure and leveling function to improve the printing effect and the uniformity of the graphics printing on the substrate, which facilitates the use of the leveling device of the two-color screen printing machine. Anti-slip buffer pads made of nitrile rubber are attached to the lower surface of the pressure plate 210 and the upper surface of the fixed base plate 211. The buffer pads can not only prevent slippage but also prevent slippage. The increased friction between the aluminum frame 3 and the pressure plate 210 and the fixed base plate 211 prevents the aluminum frame 3 from shifting due to vibration during printing. It also buffers the impact force when the pressure plate 210 presses down, preventing the edges of the aluminum frame 3 from deforming due to rigid compression. When the screen printing machine body 1 is printing on the substrate, the flat plate 4 can be slidably removed from the mounting plate 402, thus not affecting the printing work on the substrate and facilitating the connection and use of the flattening device components of the two-color screen printing machine. The drive components a202, b207 and c406 can be electric telescopic rods. The electric telescopic rods convert electrical energy and mechanical energy to drive the internal mechanical structure to achieve linear telescopic movement, enabling the components of the installation assembly to move and be used.
[0026] Example 2
[0027] like Figure 2 and Figure 3 As shown, the present invention proposes a leveling device for a two-color screen printing machine. Based on the above embodiments, this embodiment also details the specific components such as the leveling plate 4 and their assembly method.
[0028] Further explanation: the fixed plate 204 and the inner side plate 206 are respectively provided with corresponding openings a and b. The guide rod 209 passes through openings a and b and is connected to the pressure plate 210. The guide rod 209 can slide vertically along openings a and b to ensure that the pressure plate 210 remains horizontal during the lifting and lowering process. The upper surface of the aluminum frame 3 is detachably connected to the pressure plate 210, and the lower surface of the aluminum frame 3 is detachably connected to the fixed base plate 211. The installation position of the aluminum frame 3 corresponds to the core component of the screen printing machine body 1. The aluminum frame 3 is located directly above the screen printing table component of the screen printing machine body 1 and directly below the photosensitive emulsion component of the screen printing machine body 1, ensuring that the photosensitive emulsion can be accurately dripped into the aluminum frame 3, and the screen inside the aluminum frame 3 is aligned with the substrate of the screen printing table. The lower surface of the flat plate 4 is covered with a flexible buffer layer. The flat plate 4 is connected to the substrate, and the substrate is placed on the screen printing table. By placing the substrate to be printed on the screen printing table component of the screen printing machine body 1, and then operating the leveling plate 4 to level the substrate, the leveling plate 4 is then disassembled and placed aside for the next use. Finally, the aluminum frame 3 and the mounting component are connected so that the aluminum frame 3 is positioned above the screen printing table. Through the core component of the screen printing machine body 1, the mounting component is moved downwards, so that the aluminum frame 3 is connected to the substrate. The photosensitive adhesive of the screen printing machine body 1 moves from one side of the screen to the other side, thus printing the image onto the substrate.
[0029] The working principle of this utility model is as follows: During use, the operator places the substrate to be printed on the screen printing table of the screen printing machine body 1. The operator aligns the two ends of the flat plate 4 with the mounting plate 402, and then pushes the flat plate 4 towards the fixing block 403 until the positioning block 401 at one end of the flat plate 4 is fitted into the positioning groove. The positioning block 401 and the positioning groove are magnetically connected, so that the positioning block 401 and the fixing block 403 are made of magnetic material, thus completing the installation of the flat plate 4 and the mounting plates 402 on both sides. Then, the driving component c406 is activated. The driving end of the driving component c406 drives the splicing rod 405 to move, and the splicing rod 405 drives the two sides... The connecting rod 404 drives the mounting plate 402 downward, thereby moving the flat plate 4 downward and applying downward pressure to flatten the surface of the substrate. Due to the stable connection between the flat plate 4 and the mounting plate 402, and the precise engagement and adsorption of the positioning block 401 and the positioning groove, the flat plate 4 will not shift or shake during movement and pressure application, ensuring uniform pressure on the substrate surface. After the flattening operation is completed, the driving end of the drive component c406 retracts, driving the splicing rod 405, connecting rod 404, and mounting plate 402 upward, thus detaching the flat plate 4 from the substrate. On the surface, the operator can then proceed with subsequent printing processes. The drive component c406 moves upwards, and after movement, the entire flat plate 4 is disassembled. The screen printing machine body 1 then operates, enabling the printing of images and text onto the substrate fixed to the mounting assembly. When changing the printed image, the drive component b207 is activated. The drive end of drive component b207 moves the moving plate 208, which in turn moves the guide rod 209. The guide rod 209 moves the pressure plate 210 upwards. The pressure plates 210 on both sides operate in the same way, separating them from the upper surfaces of both ends of the aluminum frame 3, thus allowing the aluminum frame 3 to be disassembled and the printed image to be changed. The operator places the two ends of the replacement aluminum frame 3 on the fixed base plate 211, and then operates the drive component b207 to move the pressure plate 210 downwards to the surfaces of both ends of the aluminum frame 3, so as to cooperate with the fixed base plate 211 to install the aluminum frame 3. When the length of the aluminum frame 3 is different, the drive component a202 is activated. The drive end of the drive component a202 drives the pressure plate 210 and other components to move, thereby adjusting the spacing between the pressure plates 210 to meet the installation requirements of the aluminum frame 3 and improve the overall structure of the leveling device of the two-color screen printing machine. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
