Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically to a quick-release structure that facilitates the replacement of printing plates. Background Technology

[0002] Printing plates are the core medium in the printing process. They are tools that create "ink-repellent zones" and "ink-repellent zones" on substrates such as metal, resin, and screens, based on the designed text and images. Essentially, they are the key transfer medium for transferring images and text from the design draft to the printing substrate (paper, plastic, etc.). Printing plates are mainly used to accurately reproduce and fix the designed text, patterns, and other printing information, ensuring the accuracy and integrity of the content. Through the difference between their own "ink-repellent" and "ink-repellent" zones, ink is only allowed to adhere to the areas where the image and text need to be displayed during printing, achieving precise ink distribution. Under printing pressure or other external forces, the adhered ink is stably and evenly transferred to the surface of the printing substrate, ultimately completing the production of the printed matter and supporting the mass production of various printed materials such as books, packaging, and posters.

[0003] When manually disassembling and assembling printing plates for gravure printing machines, the shaft head nut of the top plate shaft needs to be loosened first. Currently, the shaft head nut can only be turned by a manual wrench, which is time-consuming and laborious, affecting production efficiency. This problem has not been solved in the existing technology. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: A quick-release structure for easy printing plate replacement includes a printing plate roller 1, with transmission components 14 rotatably mounted at both ends of the printing plate roller 1, and two sets of fixing grooves 2 for fixing both ends of the printing plate provided on one side of the printing plate roller 1.

[0018] The printing plate roller 1 serves as the base for supporting the printing plate. Its surface is used to mount the printing plate, and its two ends are connected to the power mechanism of the gravure printing machine through the transmission assembly 14 to achieve rotation. It is the core component for transferring the printing plate and completing the ink transfer during the printing process. At the same time, the fixing groove 2 opened on the printing plate roller 1 is used to position the two ends of the printing plate, providing a basic structure for the installation of the printing plate. Through its own rotation and cooperation with other components, it achieves stable operation and quick replacement of the printing plate.

[0019] It also includes a fixing component, which includes two sets of clamping rods 3. The surface of the clamping rods 3 is provided with an anti-slip layer. The clamping rods 3 are slidably installed in the moving groove 4 opened in the printing plate roller 1 and can rotate in the moving groove 4. The moving groove 4 is set above the fixed groove 2. The two ends of the clamping rods 3 are respectively rotatably connected to the inner side of two sets of fixed plates 5. The fixed plates 5 are fixedly connected to the transmission component 14. The moving groove 4 is connected to the fixed groove 2. The clamping rods 3 are slidably engaged with the fixed groove 2 and can rotate in the fixed groove 2.

[0020] The fixing component is mainly used for simple and quick installation and removal of the printing plate. The fixing component is based on two sets of clamping rods 3. The clamping rods 3 are slidably installed in the moving groove 4 of the printing plate roller 1 and can slide and rotate in the fixing groove 2. Together with the fixing plate 5, they can clamp and fix the two ends of the printing plate. Its function is to stably restrict the two ends of the printing plate in the fixing groove 2. The printing plate can be quickly installed and removed without the need for tools through structural linkage, simplifying the operation process and improving the replacement efficiency.

[0021] It also includes a tightening assembly, which includes two sets of driven gears 6. The two sets of driven gears 6 are coaxially arranged and fixedly connected to the two sets of clamping rods 3 respectively. The two sets of driven gears 6 mesh with the driving gear ring 7. The driven gears 6 are rotatably mounted on the outside of the fixed plate 5. The driving gear ring 7 is rotatably mounted on the outside of the fixed plate 5. An adjusting seat 8 is fixedly mounted on the outside of the driving gear ring 7. The adjusting seat 8 has an inner cavity 9.

[0022] By setting up a tightening component, the pressure rod 3 can be rotated, which pulls both ends of the printing plate into the fixing groove 2, thus ensuring that the printing plate is tightly attached to the surface of the printing plate roller 1 and guaranteeing the printing effect. The tightening component consists of a meshing structure of driven gear 6 and driving gear ring 7. Driven gear 6 and pressure rod 3 are coaxially fixed. The rotation of driving gear ring 7 drives driven gear 6 and pressure rod 3 to rotate. The friction between pressure rod 3 and printing plate pulls both ends of printing plate into the fixing groove 2, making the printing plate tightly attached to the surface of printing plate roller 1, eliminating loose gaps, ensuring the stability of printing plate position during printing, and guaranteeing the clarity and consistency of printed images and text.

[0023] The inner cavity 9 is equipped with a ratchet 10 and a check pawl 11. One end of the check pawl 11 abuts against the ratchet 10. One side of the ratchet 10 is rotatably connected to the fixed plate 5 through a rotating ring 12. The other side of the ratchet 10 is fixedly connected to the inner wall of the adjusting seat 8. The other end of the check pawl 11 is rotatably mounted on a rotating shaft 13. The rotating shaft 13 is fixedly connected to the fixed plate 5. A torsion spring is mounted on the surface of the rotating shaft 13. One end of the torsion spring is fixedly connected to the check pawl 11, and the other end of the torsion spring is fixedly connected to the rotating shaft 13.

[0024] By setting a ratchet 10 and a check pawl 11, the two work together to form a one-way locking mechanism. The ratchet 10 rotates with the adjusting seat 8, and the check pawl 11 always abuts against the tooth surface of the ratchet 10 under the action of the torsion spring. When the driving gear ring 7 drives the adjusting seat 8 and the ratchet 10 to rotate in the forward direction to tighten the printing plate, the check pawl 11 can be locked into the tooth groove of the ratchet 10 to prevent it from rotating in the reverse direction, thereby maintaining the tightened state and playing a role in stabilizing the tightening effect and preventing loosening.

[0025] In practical use, the device is installed in the designated position. First, the printing plate roller 1 is connected to the gravure printing machine power mechanism through the transmission component 14. Then, the printing plate is unfolded and one end is placed into the fixing groove 2 above the printing plate roller 1. Next, the power mechanism of the gravure printing machine drives the transmission assembly 14 to rotate in the forward direction. The transmission assembly 14 drives the two sets of clamping rods 3 to rotate through the fixed plate 5 and move downward in the moving groove 4. The clamping rods 3 move downward to press one end of the printing plate against the fixed groove 2. Meanwhile, when the clamping rod 3 moves to the bottom of the fixed groove 2, it will transmit power to the printing plate roller 1. The printing plate roller 1 will start to rotate around the transmission assembly 14. Since one end of the printing plate is fixed to the printing plate roller 1, the printing plate is pulled. After the printing plate roller 1 rotates one revolution, the control transmission assembly 14 is turned off to stop rotating. At this time, the printing plate rotates one revolution around the printing plate roller 1. The same principle controls the printing plate roller 1 to reverse a certain angle, so that the clamping rod 3 returns to the top of the moving groove 4. Then, the other end of the printing plate is placed into the fixed groove 2 below the printing plate roller 1. The printing plate roller 1 is controlled to rotate forward a certain angle, and the clamping rod 3 presses and fixes both ends of the printing plate in the fixed groove 2. Then the adjusting seat 8 on the outside of the active gear ring 7 can be rotated to drive the active gear ring 7 to rotate. The driven gear 6 drives the clamping rod 3 to rotate. The friction between the clamping rod 3 and the printing plate pulls both ends of the printing plate into the fixed groove 2 until the printing plate is tightly attached to the roller surface. During this process, the ratchet 10 and the anti-return pawl 11 cooperate under the action of the torsion spring to prevent the adjusting seat 8 from rotating in the opposite direction to maintain the tightened state. After installation, start the gravure printing machine. The printing plate roller 1 will rotate through the transmission component 14 to start printing. If the printing plate needs to be replaced, control the printing plate roller 1 to rotate in the opposite direction by a certain angle to release the printing plate. Then, directly remove the old printing plate and repeat the above steps to install the new printing plate. The entire operation can be completed without the aid of tools.

[0026] 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, the scope of which is defined by the appended claims and their equivalents.
