Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a rotary screen printing plate. Background Technology

[0002] The rotary screen printing plate is the core component in the rotary screen printing process. It has a cylindrical structure and its surface is designed with through holes and closed areas according to the printing pattern. During the printing process, ink or pigment is transferred to the substrate (such as continuous materials such as fabric, wallpaper, and plastic film) through the through holes on the screen under pressure, thereby forming the desired pattern.

[0003] Rotary screen printing screens typically consist of an etched steel mesh and two rotary screen rollers. The etched steel mesh is supported and fixed by the rotary screen rollers at both ends, and the exposed image is formed by coating with photosensitive paste. During printing, the substrate contacts the bottom of the etched steel mesh, and the rotary screen rollers drive the etched steel mesh to rotate, ensuring that the substrate and the steel mesh move synchronously, so that the ink or pigment is accurately transferred to the substrate through the exposed image area.

[0004] However, traditional rotary screen printing stencils lack internal support and are prone to deformation under pressure during the printing process, which can lead to pattern distortion, affecting print quality and operational stability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rotary screen printing plate to improve the quality of rotary screen printing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary screen printing plate, comprising a rotary screen body and two rotary screen rollers, each of the two rotary screen rollers having an annular mounting groove on one adjacent side, and each of the two annular mounting grooves being connected to a plurality of fixing components, the two ends of the rotary screen body being located inside the two annular mounting grooves respectively and being connected and fixed by the plurality of fixing components, and a support component being connected between the two rotary screen rollers, the two ends of the support component being connected to the inner side of the two rotary screen rollers respectively, and the support component abutting against the inner wall of the rotary screen body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 8 A rotary screen printing plate includes a rotary screen body 1 and two rotary screen rollers 2. Each of the two rotary screen rollers 2 has an annular mounting groove 201 on an adjacent side. Several fixing components 3 are connected in each of the two annular mounting grooves 201. The two ends of the rotary screen body 1 are located inside the two annular mounting grooves 201 and are connected and fixed by several fixing components 3. A support component 4 is connected between the two rotary screen rollers 2. The two ends of the support component 4 are connected to the inner side of the two rotary screen rollers 2 respectively, and the support component 4 abuts against the inner wall of the rotary screen body 1.

[0027] like Figures 1 to 8 As shown, the main improvement of this utility model lies in supporting the inner side of the rotary screen to prevent the rotary screen from deforming during the compression printing process, thereby improving the printing quality of the rotary screen. Figures 1 to 8As shown, in use, the rotary screen printing plate of this utility model is first installed on the inner side of one of the rotary screen rollers 2. Then, the rotary screen body 1 is installed from one end of the support component 4 into the annular mounting groove 201 of the rotary screen roller 2, and the end of the rotary screen body 1 is installed in the annular mounting groove 201 using the fixing component 3. Next, the annular mounting groove 201 of the other rotary screen roller 2 is fitted onto the other end of the rotary screen body 1, and the end of the rotary screen body 1 is also fixed using the fixing component 3. Finally, the rotary screen roller 2 is connected to the support component 4. During rotary screen printing, the support component 4 between the two rotary screen rollers 2 can support the inner side of the rotary screen body 1, thereby preventing the rotary screen body 1 from being deformed or dented due to pressure, and improving the performance of the rotary screen body 1 during printing. To ensure stability during the printing process and improve printing results, it is important to note that the support component 4 should contact the photosensitive emulsion area of ​​the rotary screen body 1, and not the ink outlet area, to avoid obstructing ink flow and affecting the printing effect. The rotary screen body 1 can be made of woven stainless steel mesh, and the traditional photosensitive emulsion plate-making mode can be replaced with the TPI functional film plate-making mode, thereby significantly improving printing precision and printing durability. In addition, the original split steel mesh support roller is designed as an integral support roller to ensure the printing stability of the original steel mesh.

[0028] like Figures 1 to 6 As shown, the support assembly 4 includes two support bearings 41 and several support rods 42. The several support rods 42 are symmetrically distributed around the axis of the circular mesh body 1. The two support bearings 41 are fixedly connected to the inner walls of the two circular mesh rollers 2 respectively. The two ends of the several support rods 42 are respectively connected to the inner rings of the two support bearings 41. The several support rods 42 rotate and move inside the circular mesh body 1 through the two support bearings 41. Several support columns 43 are connected to the side of the several support rods 42 near the inner wall of the circular mesh body 1. The ends of the several support columns 43 away from the support rods 42 abut against the inner wall of the circular mesh body 1. Multiple support rods 42 are installed and fixed inside the rotary screen body 1 via support bearings 41, allowing the support rods 42 to rotate and move inside the rotary screen cylinder 2. When the squeegee extends into the rotary screen cylinder 2 to perform squeegee processing, the support rods 42 do not obstruct the squeegee. At the same time, multiple support columns 43 on the support rods 42 contact and abut against the inside of the rotary screen body 1, thereby providing multi-point support for the inside of the rotary screen body 1, improving the stability of the rotary screen body 1 during printing and rolling. Furthermore, any support column 43 must avoid the ink outlet position of the mesh of the rotary screen body 1 to ensure smooth printing operation and avoid printing blanks.

[0029] like Figures 1 to 5As shown, both ends of the support rod 42 are connected to first bolts 44. The threaded rods of the two first bolts 44 pass through both ends of the support rod 42 and are threadedly connected to the inner rings of the two support bearings 41. The two ends of the support rod 42 are fixed to the inner rings of the inner support bearings 41 of the two circular mesh rollers 2 by the first bolts 44, thereby providing effective support for the circular mesh body 1 between the two circular mesh rollers 2.

[0030] like Figures 5 to 6 As shown, a sliding groove 401 is provided on the side of the support rod 42 near the circular mesh body 1, and an adjustment groove 402 is provided on the side of the sliding groove 401 away from the circular mesh body 1. Several sliders 45 are slidably connected in the sliding groove 401. The sides of the sliders 45 away from the sliding groove 401 are respectively fixedly connected to several support columns 43. A second threaded hole 403 is provided on the side of the slider 45 away from the support column 43. A second bolt 46 is connected in the second threaded hole 403. The threaded rod of the second bolt 46 passes through the adjustment groove 402 and is threadedly connected to the second threaded hole 403. The nut of the second bolt 46 abuts against the side of the support rod 42 away from the support column 43. The support column 43 can slide laterally within the groove 401 via the slider 45, thereby adjusting the position of the support column 43 according to the ink outlet position on the rotary screen body 1. This prevents the support column 43 from clogging the ink outlet position of the rotary screen body 1. Once the support column 43 has moved to the appropriate position, the second bolt 46 can be rotated to engage with the slider 45, which is threadedly connected to it. This causes the second bolt 46 and the slider 45 to press against the support rod 42, thus fixing the position of the support column 43. This ensures that the position of the support column 43 will not shift during the printing operation, improving the support stability of the rotary screen body 1.

[0031] like Figures 2 to 8 As shown, a ball bearing 47 is embedded at the end of the support column 43 near the support rod 42, and the end of the ball bearing 47 away from the support column 43 abuts against the inner side of the round mesh body 1. The end of the support column 43 abuts against the inner side of the round mesh body 1 through the embedded ball bearing 47. When the scraper performs the scraping operation, the support rod 42 rotates inside the round mesh body 1. At this time, the support column 43 supports the inner side of the round mesh body 1 through the rolling ball bearing 47, which can greatly reduce the friction between the support column 43 and the round mesh body 1 and reduce frictional damage to the round mesh body 1.

[0032] like Figures 2 to 8As shown, the fixing component 3 includes a pressing bolt 31 and a pressing plate 32. A T-shaped hole 301 is provided on one side of the pressing plate 32, and a rotating block 33 is rotatably connected inside the T-shaped hole 301. The threaded rod of the pressing bolt 31 passes through the outside of the circular screen roller 2 to the annular mounting groove 201 and is fixedly connected to the rotating block 33. The pressing bolt 31 is threadedly connected to the circular screen roller 2. After inserting the end of the circular screen body 1 into the annular mounting groove 201, the pressing bolt 31 is turned to drive the pressing plate 32 to move towards the inside of the annular mounting groove 201, thereby pressing the end of the circular screen body 1 against the inside of the annular mounting groove 201, completing the installation and fixing of the circular screen body 1 on the circular screen roller 2.

[0033] like Figures 2 to 8 As shown, a soft pad 34 is fixedly connected to the side of the extrusion plate 32 away from the extrusion bolt 31, and the side of the soft pad 34 away from the extrusion plate 32 abuts against the edge of the round mesh body 1. By using the soft pad 34 to extrude and fix the round mesh body 1, the extrusion damage caused to the round mesh body 1 can be reduced. At the same time, during the extrusion process, the soft pad 34 can be squeezed into the mesh of the round mesh body 1, increasing the contact area with the round mesh body 1 and improving the fixing effect of the round mesh body 1.

[0034] like Figure 8 As shown, an annular mounting groove 202 is provided on one side of the annular mounting groove 201 near the inner ring of the circular screen roller 2. Several reinforcing nails 21 are fixedly connected in the annular groove 202. When the soft pad 34 presses the end of the circular screen body 1 against the inner side of the annular mounting groove 201, the circular screen body 1 will move into the annular groove 202 due to the pressure of the soft pad 34, and the reinforcing nails 21 will be inserted into the mesh of the circular screen body 1, further improving the connection between the circular screen body 1 and the circular screen roller 2, and ensuring that the end of the circular screen body 1 is not easy to fall off from the circular screen roller 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
