Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing, in particular to a profiling positioning device used for screen printing. Background Art

[0002] Currently, screen printing often encounters raised areas on the back of printed materials. These raised areas prevent the material from being placed directly and evenly on the printing surface, significantly complicating the printing operation. Traditional printing methods often fail to ensure print quality and precision when dealing with such materials with raised back surfaces. Because the printing plate doesn't fully adhere to the printing surface, problems such as blurred patterns, uneven colors, and positional deviations can easily occur during printing, severely impacting the quality and aesthetics of the finished product. Utility Model Content

[0003] In order to solve the problem described in the background art that the printing plate cannot be completely fitted with the printing surface, which easily leads to blurred patterns, uneven colors, position deviations and other problems during the printing process, seriously affecting the quality and aesthetics of the printed product, the present invention proposes the following technical solutions:

[0005] Wherein, one side of the printing plate is raised to form a plurality of abutment portions and positioning columns matching the contoured grooves, and the other side of the printing plate is flat.

[0006] Furthermore, the second surface of the bottom plate is recessed inward to form an air guide port, and the limit block and the ventilation hole are both located in the air guide port; when the printing press is running, the fan under the printing press table adsorbs the printing plate through the ventilation hole.

[0007] Furthermore, the first surface of the bottom plate is provided with positioning holes distributed along the periphery of the abutting portion, and when the printing plate is fixedly connected to the bottom plate, each of the positioning posts is inserted into the positioning hole.

[0008] Furthermore, the limiting blocks and the ventilation holes are respectively arranged at intervals in the air guide port, and each limiting block is located between adjacent limiting blocks.

[0009] Furthermore, the positioning holes are distributed along the periphery of the array formed by the ventilation holes, and the diameter of the positioning holes is larger than the diameter of the ventilation holes.

[0010] Furthermore, the bottom plate includes a base and a contoured plate, the air guide port is located on one side of the base, and a mounting groove is provided on the other side of the base; the positioning hole is located on the surface of the base at the outer edge of the mounting groove; the surface of the contoured plate is provided with a connecting hole matching the ventilation hole, the contoured plate is embedded in the mounting groove, and the contoured groove is located on the surface of the contoured plate.

[0015] In order to make the purpose, technical solutions and advantages of this application more clear, the present invention will be described in further detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] It should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0017] Figure 1 The figure is a schematic diagram of the exploded structure of a contour positioning device for screen printing according to an embodiment of the utility model. Figure 2 2 is a schematic diagram of the back structure of a contour positioning device for screen printing according to an embodiment of the present utility model.

[0018] Refer to Figure 1 and Figure 2 According to an embodiment of the present invention, a contour positioning device for screen printing is disposed between a screen printing plate and a printing press table, comprising a base plate 1 and a printing plate 2. Base plate 1 is fixed to the printing press table. A contour groove 11 and ventilation holes 12 are defined on the first side of base plate 1. A second side of base plate 1 has protrusions spaced apart to form stoppers 13 that align with the printing press table. One side of printing plate 2 is embedded in contour groove 11, while the other side of printing plate 2 abuts against the screen printing plate. The printing plate 2 and base plate 1 are connected by suction via a fan within the printing press table.

[0019] Specifically, one side of the printing plate 2 is raised to form an abutment portion 14 and a positioning post 15 that mate with the contoured groove 11. The other side of the printing plate 2 is flat and abuts against the screen printing plate. After printing is complete, the flat surface of the printing plate 2 can be lifted to release the connection between the printing plate 2 and the base plate 1, allowing the next printing plate 2 to be replaced and screen printing to be repeated.

[0020] Furthermore, the second surface of the base plate 1 is recessed inward, forming an air vent 16 that aligns with the printing press surface. Once the base plate 1 is secured to the printing press surface, the air vent 16 aligns with the air inlet of the fan within the printing press surface. During the printing process, the wind generated by the fan draws air from the printing plate 2 through the vents 12, temporarily maintaining a relative stillness between the printing plate 2 and the base plate 1. This allows ink to adhere stably to the printing plate 2 after it seeps off the screen printing plate during the screen printing process.

[0021] Specifically, the first surface of the base plate 1 is provided with positioning holes distributed along the periphery of the abutment portion 14. During the screen printing process, when replacing the next printing plate 2, the positioning posts 15 on the printing plate 2 can be aligned with the positioning holes on the surface of the base plate 1, so that the installation can be carried out quickly. The positioning holes, the limiting blocks 13, and the ventilation holes 12 are all located in the area where the air guide 16 is located. Among them, the limiting blocks 13 and the ventilation holes 12 are respectively arranged at intervals in the air guide 16 to form an array, and each limiting block 13 is located between two adjacent ventilation holes 12. The positioning holes are arranged at intervals along the periphery of the array formed by the ventilation holes 12, and the diameter of the positioning holes is larger than the diameter of the ventilation holes 12. The positioning holes and the ventilation holes 12 can be quickly distinguished by their size, so that the operator can quickly assemble and replace the printing plate 2. When screen printing is performed, the positioning posts 15 on one side of the printing plate 2 block the positioning holes. The wind force generated by the fan in the printing press causes the air to flow from the printing plate 2 side to the printing press table side. The narrow diameter of the ventilation hole 12 further increases the air flow speed in the ventilation hole 12 and at the same time improves the adsorption effect generated by the fan.

[0022] Figure 3The figure is a schematic diagram of the exploded structure of a contour positioning device for screen printing according to another embodiment of the present invention.

[0023] Refer to Figure 1 and Figure 3 In another embodiment of the present invention, the base plate 11 includes a base 15 and a profile plate 16. An air duct 14 is located on one side of the base, and a mounting slot is provided on the other side of the base. The vents 12 and the stoppers 13 are both located within the mounting slots, spaced apart within the mounting slots 161. Positioning holes 15 are located on the surface of the base 16 at the outer edge of the mounting slots 161. A profile plate 17 is embedded within the mounting slots 161. Connecting holes 171 are provided on the profile plate surface to match the vents 12. The profile slots 11 are located on the side of the profile plate 17 closest to the printing plate 2. During screen printing, positioning posts 15 on one side of the printing plate 2 block the positioning holes. The wind generated by the fan within the printing press causes air to flow from one side of the printing plate 2 toward the printing press table, connecting the profile plate 17 to the printing plate 2 through wind suction. The base 16 stabilizes the profile plate 17 through wind suction, thus completing the connection with the printing plate 2. In this embodiment, the split design of the base plate 1 accelerates the speed of replacing the contour plate 17 .

[0024] In summary, the present invention maintains a relatively static state by connecting the bottom plate and the printing plate through wind adsorption, so that the screen printing plate has a stable and flat bearing surface for screen printing during the printing process.
