It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown: A flexographic printing plate fixing device includes a first supporting square plate 13, an open-type supporting box 2, a positioning post 1, a positioning elongated plate 3, and a limiting upright plate 11. A fixing and lifting component for fixing a square flexographic printing plate and improving the fixing effect is fixedly installed on the top of the first supporting square plate 13. The fixing and lifting component includes the open-type supporting box 2, the bottom of which is fixedly installed on the top of the first supporting square plate 13. A square flexographic printing plate body 15 is movably connected inside the open-type supporting box 2. A U-shaped pressure plate 14 is movably connected to the outer surface of the main body 15. A first positioning component of the positioning and lifting assembly is fixedly installed on the top of the lifting assembly. The first positioning component includes a positioning column 1 and a positioning long plate 3. The bottom of the positioning column 1 and the bottom of the positioning long plate 3 are both fixedly installed on the top of the open support box 2. The positioning column 1 and the positioning long plate 3 are both movably installed inside the plate body of the U-shaped pressure plate 14. A first limiting component of the limiting and lifting assembly is fixedly installed on one side of the lifting assembly. The first limiting component includes a limiting upright plate 11. One side of the limiting upright plate 11... The first screw 12 is threadedly connected to the inside of the limiting plate 11 and is threaded to the U-shaped pressure plate 14. Through the arrangement of the first supporting square plate 13, the fixed lifting assembly, the first positioning assembly, and the first limiting assembly, the fixed lifting assembly can fix the square flexible printing plate and improve the fixing effect; the first positioning assembly can position the fixed lifting assembly; and the first limiting assembly can limit the fixed lifting assembly. The setting of the component and the first limiting component enables the device to fix the square flexible printing plate during flexographic printing, when changing the square flexographic printing plate, and before installing the square flexographic printing plate onto the flexographic printing machine. When using the device to fix the square flexographic printing plate, the device can securely fix the square flexographic printing plate, preventing the fixing effect from being reduced due to the loosening of the square flexographic printing plate inside the device, and thus improving the fixing effect.

[0023] In use, the initial state of this device is as follows: the main body 15 of the square flexible printing plate is not fixed, the first screw 12 is threadedly connected to the U-shaped pressure plate 14, and the second screw 4 is threadedly connected to the threaded groove 17. When performing flexible printing, when changing the square flexible printing plate, before installing the square flexible printing plate onto the flexible printing machine, when it is necessary to use this device to fix the square flexible printing plate, rotate the first screw 12 to disengage the first screw 12 from the U-shaped pressure plate 14 and place one end of the first screw 12 inside the limiting plate 11. Move the U-shaped pressure plate 14 upward so that it slides upward along the positioning post 1 and the positioning long plate 3 respectively. When the U-shaped pressure plate 14 disengages from the positioning post 1 and the positioning long plate 3 respectively, the top of the open support box 2 is opened.

[0024] After the top of the open support box 2 is opened, move the square flexible printing plate body 15 and place the bottom end of the square flexible printing plate body 15 into the interior of the open support box 2. Move the U-shaped pressure plate 14 so that the positioning post 1 and the positioning long plate 3 are inserted into the plate body of the U-shaped pressure plate 14, and insert the top end of the square flexible printing plate body 15 into the interior of the U-shaped pressure plate 14. Then, the U-shaped pressure plate 14 slides down along the positioning post 1, the positioning long plate 3, and the square flexible printing plate body 15. When both the positioning pin 1 and the positioning plate 3 are fully inserted into the body of the U-shaped pressure plate 14, the bottom of the top of the square flexible printing plate body 15 is located inside the U-shaped pressure plate 14, and the bottom of the U-shaped pressure plate 14 contacts the top of the bottom of the square flexible printing plate body 15. The first screw 12 is rotated in the opposite direction to make the first screw 12 threadedly connected to the U-shaped pressure plate 14, so that the square flexible printing plate body 15 can be fixed. At this time, this device can be used to fix the square flexible printing plate.

[0025] When using this device to fix a square flexible printing plate, the bottom of the top of the square flexible printing plate body 15 is located inside the U-shaped pressure plate 14, and the bottom of the U-shaped pressure plate 14 contacts the top of the bottom of the square flexible printing plate body 15, so that the square flexible printing plate body 15 can be firmly fixed, preventing the square flexible printing plate body 15 inside the device from loosening, and improving the fixing effect of the device.

[0026] When it is necessary to mount the square flexible printing plate body 15 onto the positioning shaft of the flexible printing machine, move this device so that the positioning shaft of the flexible printing machine passes through the mounting hole inside the arc-shaped long rod 8. At this time, the square flexible printing plate body 15 can be mounted onto the positioning shaft of the flexible printing machine.

[0027] In summary, during flexographic printing, when changing to a square flexographic printing plate, before installing the square flexographic printing plate onto the flexographic printing machine, this device can securely fix the square flexographic printing plate. This prevents the square flexographic printing plate from loosening inside the device, thus improving the fixing effect.

[0028] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown: A printing plate fixing device for flexible printing includes a first supporting square plate 13, a convex disk 16, a gate-shaped long plate 10, and a limiting long plate 5. A convenient angle assembly for adjusting the fixing angle of the fixing component is fixedly installed at the bottom of the first supporting square plate 13. The convenient angle assembly includes the convex disk 16, the top of which is fixedly installed at the bottom of the first supporting square plate 13. A support disk 6 is rotatably connected to the outer surface of the convex disk 16. The support disk 6 is rotatably connected to the first supporting square plate 13. Multiple threaded grooves 17 are respectively opened on the top of the support disk 6. A second support plate 7 is fixedly connected to the bottom of the disk 6. An arc-shaped long rod 8 is fixedly connected to the bottom of the second support plate 7. The arc-shaped long rod 8 has mounting holes inside. A second positioning component of the positioning corner assembly is fixedly installed on one side of the first support plate 13. The second positioning component includes a portal-shaped long plate 10. One side of the portal-shaped long plate 10 is fixedly installed on one side of the first support plate 13. The portal-shaped long plate 10 is rotatably connected to the support disk 6. A positioning ring 9 is fixedly connected to one inner side of the portal-shaped long plate 10. The positioning ring 9 is rotatably installed inside the support disk 6. A second limiting component is fixedly installed on one side of the first supporting square plate 13. The second limiting component includes a limiting long plate 5, one side of which is fixedly installed on one side of the first supporting square plate 13. The limiting long plate 5 is rotatably connected to the supporting plate 6. The inner thread of the limiting long plate 5 is connected to a second screw 4, which is threadedly connected to a threaded groove 17. Through the arrangement of the first supporting square plate 13, the corner component, the second positioning component, and the second limiting component, the corner component can easily adjust the fixed angle of the fixed component, the second positioning component can position the corner component, and the second limiting component can limit the corner component. When performing flexographic printing, when changing the square flexographic printing plate, before installing the square flexographic printing plate onto the flexographic printing machine, after fixing the square flexographic printing plate using this device, when the device needs to adjust the fixed angle, the fixed angle of this device can be changed. This avoids increasing the difficulty of adjusting the fixed angle due to the difficulty in adjusting the fixed angle, and makes it easy to adjust the fixed angle.

[0029] When using this device for flexographic printing, when changing to a square flexographic printing plate, before installing the square flexographic printing plate onto the flexographic printing machine, after fixing the square flexographic printing plate using this device, when the device needs to adjust the fixing angle, rotate the second screw 4 to disengage the second screw 4 from the threaded groove 17 and position one end of the second screw 4 inside the limiting plate 5. Rotate the first support square plate 13 so that the first support square plate 13, the gate-shaped long plate 10, and the limiting plate 5 all rotate along the support plate 6, causing the positioning ring 9 to rotate along the inside of the support plate 6, causing the convex plate 16 to rotate along the inside of the support plate 6, and causing the open support box 2, the U-shaped pressure plate 14, and the main body 15 of the square flexographic printing plate to rotate, allowing the fixing angle of this device to be changed. When the fixing angle of this device is the required fixing angle, and when the second screw 4 corresponds to the threaded groove 17, rotate the second screw 4 in the opposite direction to thread the second screw 4 into the threaded groove 17. At this time, the fixing angle of this device can be adjusted.

[0030] When adjusting the fixed angle, the first support plate 13, the gate-shaped long plate 10 and the limiting long plate 5 all rotate along the support plate 6, and the positioning ring 9 rotates along the inside of the support plate 6, and the convex plate 16 rotates along the inside of the support plate 6, making it easy for the device to adjust the fixed angle.

[0031] In summary, when performing flexographic printing, before installing a square flexographic printing plate onto the flexographic printing machine, this device is used to fix the square flexographic printing plate. When the device needs to adjust the fixing angle, the fixing angle can be changed, thus avoiding the difficulty of adjusting the fixing angle and making it easy to adjust the fixing angle.
