Description

Technical Field

[0001] This utility model relates to the technical field of printing plate clamping devices, specifically a novel flexible printing plate clamping device. Background Technology

[0002] A flexible printing plate clamp, often simply called a plate cylinder or mounting cylinder, is a core component of a flexographic printing press. Its main function is to precisely fix and support the flexible printing plate and mount it onto the printing unit of the printing press. Flexographic printing is a letterpress printing technology that uses flexible printing plates (usually made of rubber or photosensitive resin). The clamp is the core component for mounting and fixing these flexible printing plates, and it is mounted on the printing plate cylinder of the printing press.

[0003] The core function of the flexible printing plate clamping device is to quickly, accurately, and firmly fix and tension the flexible printing plate on the surface of the printing plate cylinder. Although the flexible printing plate clamping device is a seemingly simple component, it is the bridge connecting the flexible printing plate and the rigid cylinder. It is the cornerstone for flexographic printing machines to achieve high-quality, high-efficiency, and high-stability printing. Its performance directly determines the accuracy of the printed products and the economic benefits of production. Existing plate clamping devices of this type generally do not facilitate the convenient replacement of flexible printing plates, which affects the labor intensity of manual labor, reduces the efficiency of the plate clamping device, and hinders the flexible pressing of the cloth for printing. This may result in ghosting or blurring during printing, thus affecting the printing quality of the plate clamping device. Utility Model Content

[0004] The purpose of this utility model is to provide a novel flexible printing plate clamping device to solve the problems mentioned in the background art, such as the inconvenience of changing flexible printing plates, which affects the labor intensity and efficiency of the printing plate clamping device, and the difficulty of using the printing plate clamping device to press the fabric down for printing, which may produce ghosting or blurring during printing, thus affecting the printing quality of the printing plate clamping device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel flexible printing plate clamping device, comprising a base plate and a support frame. The support frame is mounted on the top of the base plate, and a cylinder is mounted on the top of the support frame. Slide rails are symmetrically mounted on the top of the base plate away from the support frame. Movable plates are provided outside the slide rails. Slider blocks are slidably mounted on the surfaces of the slide rails. Support plates are symmetrically mounted on the bottom ends of the movable plates, and each support plate is connected to a slider. A rotating box is mounted on the top of the support plate away from the movable plate. The top of the base plate is symmetrically mounted on the side closest to the slide rail. A support base is installed, and each support base has a threaded sleeve inside. Each threaded sleeve has a threaded rod inside, and each threaded rod extends through the threaded sleeve to the outside. Each threaded rod is threadedly connected to the threaded sleeve. A handwheel is installed at one end of each threaded rod. A servo motor is installed at the top of the moving plate. A rotating shaft is installed at the output end of the servo motor. A rotating disk is installed on the side of the rotating shaft away from the servo motor. The rotating disk is slidably connected to the rotating box. A top block is installed on the side of the rotating disk away from the rotating shaft. A first roller is movably installed inside the support frame.

[0006] Preferably, the side wall of the first roller is provided with a groove, the top block cooperates with the groove, and the surface of the first roller is provided with a T-shaped groove.

[0007] Preferably, a flexible printing plate body is fitted on the outer wall of the first roller, and a first locking block is installed at one end of the flexible printing plate body.

[0008] Preferably, a second locking block is installed at the other end of the flexible printing plate body, and both the first locking block and the second locking block cooperate with the T-slot.

[0009] Preferably, a push plate is installed at the output end of the cylinder, and the push plate extends through the support frame to its outside.

[0010] Preferably, the bottom end of the push plate is equipped with three sets of springs at equal intervals, and the inside of the support frame is provided with a pressure plate.

[0011] Preferably, all the springs are connected to the pressure plate, and sliding plates are installed on both sides of the pressure plate.

[0012] Preferably, all the sliding plates are slidably connected to the support frame, and a second roller is fitted between the two sets of sliding plates, with a fabric body disposed between the second roller and the first roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the printing plate clamping device not only realizes the convenient replacement of flexible printing plates, reduces the labor intensity of manual labor, and improves the working efficiency of the printing plate clamping device, but also realizes the printing plate clamping device to elastically press the fabric down for printing, avoiding ghosting or blurring during printing, and improving the printing quality of the printing plate clamping device. The handwheel drives the threaded rod to rotate, causing the threaded rod to move the support plate. The support plate then moves the moving plate and the rotating box. The moving plate moves the servo motor and the rotating shaft. The rotating box moves the rotating disk and the top block, causing the top block to disengage from the groove. This removes the first roller from the support frame. The first and second locking blocks on both sides of the flexible printing plate body engage with the T-slots, allowing the flexible printing plate body to be fitted onto the surface of the first roller. The first roller is then placed inside the support frame. Rotating the two sets of handwheels in opposite directions causes the threaded rod to rotate in the opposite direction, causing the threaded rod to move the support plate in the opposite direction. The support plate moves the moving plate and the rotating box in the opposite direction. The moving plate moves the servo motor and the rotating shaft in the opposite direction. The rotating box moves the rotating disk and the top block in the opposite direction, allowing the top block to engage with the groove. The servo motor then drives the rotating shaft to rotate, which in turn drives the rotating disk and the top block to rotate. The top block, through the groove, drives the first roller and the flexible printing plate body on its surface to rotate and print. This allows for convenient replacement of the flexible printing plate in the printing plate clamping device, reducing manual labor intensity and improving the efficiency of the printing plate clamping device. When the fabric body needs to be pressed down for printing, the cylinder drives the push plate to move downward. The push plate drives three sets of springs to move downward. The springs drive the pressure plate to move downward elastically. The pressure plate drives the slide plate and the second roller to move downward, so that the second roller presses the fabric body downward and makes it contact the flexible printing plate body on the surface of the first roller. This realizes that the printing plate clamping device can elastically press the fabric down for printing, avoiding ghosting or blurring during printing and improving the printing quality of the printing plate clamping device.

The support frame 2 is mounted on the top of the base plate 1, and a cylinder 3 is mounted on the top of the support frame 2.

A servo motor 12 is installed at the top of the moving plate 5. A rotating shaft 13 is installed at the output end of the servo motor 12. A rotating disk 14 is installed on the side of the rotating shaft 13 away from the servo motor 12. The rotating disk 14 is slidably connected to the rotating box 8. A top block 15 is installed on the side of the rotating disk 14 away from the rotating shaft 13. A first roller 17 is movably installed inside the support frame 2. The side wall of the first roller 17 is provided with a groove 16, the top block 15 is engaged with the groove 16, and the surface of the first roller 17 is provided with a T-groove 18.

Both the first locking block 20 and the second locking block 21 cooperate with the T-slot 18. When using the flexible printing plate clamping device, manually rotate two sets of handwheels 11. The handwheels 11 drive the threaded rod 10 to rotate. With the threaded connection between the threaded rod 10 and the threaded sleeve 28, and the sliding support of the slider 6 and the slide rail 4, the threaded rod 10 drives the support plate 7 to move. The support plate 7 drives the moving plate 5 and the rotating box 8 to move. The moving plate 5 drives the servo motor 12 and the rotating shaft 13 to move. The rotating box 8 drives the rotating disk 14 and the top block 15 to move, causing the top block 15 to disengage from the groove 16, thus removing the first roller 17 from the inside of the support frame 2. With the cooperation of the first locking block 20, the second locking block 21, and the T-slot 18, the first locking blocks 20 and the second locking blocks 21 on both sides of the flexible printing plate body 19 engage with the T-slot 18, allowing the flexible printing plate body 19 to be fitted onto the surface of the first roller 17. The first roller 17 is then placed inside the support frame 2. Rotate the two sets of handwheels 11 in both directions. The threaded rod 10 is driven to rotate in the opposite direction. Under the threaded connection between the threaded rod 10 and the threaded sleeve 28, and the sliding support of the slider 6 and the slide rail 4, the threaded rod 10 drives the support plate 7 to move in the opposite direction. The support plate 7 drives the moving plate 5 and the rotating box 8 to move in the opposite direction. The moving plate 5 drives the servo motor 12 and the rotating shaft 13 to move in the opposite direction.

Under the support of the moving plate 5, the servo motor 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the rotating disk 14 and the top block 15 to rotate. With the cooperation of the top block 15 and the groove 16, the top block 15 drives the first roller 17 and the flexible printing plate body 19 on its surface to rotate and print through the groove 16. This realizes the convenient replacement of the flexible printing plate of the printing plate clamping device, reduces the labor intensity of manual labor, and improves the working efficiency of the printing plate clamping device. A push plate 22 is installed at the output end of the cylinder 3. The push plate 22 extends through the support frame 2 to its outside.

A second roller 26 is fitted between the two sets of slide plates 25. A fabric body 27 is provided between the second roller 26 and the first roller 17. When it is necessary to press the fabric body 27 for printing, the cylinder 3 is opened. Under the support of the support frame 2, the cylinder 3 drives the push plate 22 to move downward. The push plate 22 drives the three sets of springs 23 to move downward. The springs 23 drive the pressure plate 24 to move downward elastically. Under the sliding support of the slide plate 25 and the support frame 2, the pressure plate 24 drives the slide plate 25 and the second roller 26 to move downward, so that the second roller 26 presses the fabric body 27 downward and contacts the flexible printing plate body 19 on the surface of the first roller 17. This realizes that the printing plate clamping device can elastically press the fabric downward for printing, avoid ghosting or blurring during printing, and improve the printing quality of the printing plate clamping device.

[0018] Working principle: Handwheel 11 drives threaded rod 10 to rotate, causing threaded rod 10 to move support plate 7. Support plate 7 drives moving plate 5 and rotating box 8 to move. Moving plate 5 drives servo motor 12 and rotating shaft 13 to move. Rotating box 8 drives rotating disk 14 and top block 15 to move, causing top block 15 to disengage from groove 16, removing first roller 17 from inside support frame 2. First locking blocks 20 and second locking blocks 21 on both sides of flexible printing plate body 19 engage with T-slot 18, allowing flexible printing plate body 19 to be fitted onto the surface of first roller 17. First roller 17 is placed inside support frame 2. Rotating both sets of handwheels 11 in opposite directions causes threaded rod 10 to rotate in the opposite direction, causing threaded rod 10 to move support plate 7 in the opposite direction. Support plate 7 drives moving plate 5 and rotating box 8 in the opposite direction. 5 drives the servo motor 12 and the rotating shaft 13 to move in the opposite direction.

The servo motor 12 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the rotating disk 14 and the top block 15 to rotate. The top block 15 drives the first roller 17 and the flexible printing plate body 19 on its surface to rotate and print through the groove 16. When it is necessary to press the fabric body 27 down for printing, the cylinder 3 drives the push plate 22 to move downward. The push plate 22 drives the three sets of springs 23 to move downward. The springs 23 drive the pressure plate 24 to move downward elastically. The pressure plate 24 drives the slide plate 25 and the second roller 26 to move downward, so that the second roller 26 presses the fabric body 27 down and contacts the flexible printing plate body 19 on the surface of the first roller 17, thus completing the use of the printing plate clamping device.
