Description

Technical Field

[0001] This utility model belongs to the field of printing plate making technology, and specifically relates to a printing plate making device. Background Technology

[0002] In existing technologies, traditional printing plate-making equipment often faces the problem of adapting to different types of printing plates during actual use. Since the specifications and materials of printing plates vary, they usually need to be equipped with special receiving plates for fixation and support. However, the operation of changing receiving plates in existing plate-making equipment is relatively complicated and lacks flexibility. This design makes the equipment require a long adjustment time and a high level of operational proficiency to meet the needs of different printing plates, which increases the labor and time costs in the production process and thus limits the plate-making efficiency.

[0003] Furthermore, due to the cumbersome process of replacing the receiving plate, users may encounter problems such as unstable installation and inaccurate positioning caused by unreasonable equipment structure. This not only affects the clamping effect of the printing plate, but may also lead to deviations in the printing plate making process, thus affecting the final printing quality. It can be seen that the existing equipment has certain limitations in adapting to different printing plates, and cannot fully meet the requirements of rapid replacement and high-precision operation in actual production, which greatly reduces the ease of use and adaptability of the equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The replacement mechanism of this utility model realizes the quick disassembly and replacement of the receiving plate through the cooperation of the support frame, the lifting frame, the bottom sleeve, the internal rod, the central rod, the receiving plate, the pressure plate and the spring. During operation, the lifting frame is moved to drive the bottom sleeve and other parts to move up and down, thereby realizing the adjustment and fixation of the receiving plate. The receiving plate is slidably connected by the central rod, and the spring provides appropriate elastic support to ensure the stability of the receiving plate. When the receiving plate needs to be replaced, the loosening and installation can be completed quickly by operating other mechanisms, ensuring that the fixing and replacement of the receiving plate is convenient and efficient. In summary, the replacement mechanism makes the replacement process of the receiving plate simpler and faster, reduces the operation time and improves the adaptability of the equipment.

[0017] (2) The snap-fit ​​mechanism of this utility model achieves reliable snap-fit ​​and quick release of the receiving plate and the center rod through the coordinated work of the bottom sleeve, the inclined sleeve, the slider, the snap-fit ​​block, the one-way block, the one-way sleeve, the pull rope, the return spring, the pull sleeve and the guide rod. In use, the snap-fit ​​block is connected to the pull rope, and the slider slides along the inclined sleeve, thereby driving the snap-fit ​​block and the one-way block to complete the snap-fit ​​or release action. When the pull rope is pulled, the return spring provides a restoring force at the same time, ensuring the stability and accuracy of the slider action. The design of the one-way block can complete the rapid expansion and contraction through the one-way sleeve, so that the internal rod can flexibly switch between the snap-fit ​​state and the release state. In addition, the guide rod restricts the movement trajectory of the pull rope through the guide hole, ensuring the overall smooth operation of the snap-fit ​​mechanism. In summary, the snap-fit ​​mechanism achieves efficient and reliable connection and separation, and improves the overall operation convenience and stability of the receiving plate and the equipment.

[0018] (3) The moving mechanism of this utility model consists of a support frame, a moving frame and a plate maker. Through mutual cooperation, the plate maker is driven to complete the precise plate making on the surface of the printing plate. The moving frame is installed on the support frame. By controlling its moving direction and distance, the plate maker can cover the entire working area of ​​the printing plate, thereby meeting the plate making requirements of different specifications of printing plates. After the receiving plate completes the fixing of the printing plate, the moving mechanism drives the plate maker to perform efficient plate making, ensuring the uniformity and accuracy of the printed pattern, while improving the plate making speed and reducing the production cycle. In summary, the moving mechanism effectively realizes the precise movement and efficient operation of the plate maker, providing the equipment with higher flexibility and plate making quality assurance.

The support frame 1 is equipped with a replacement mechanism, which includes a moving mechanism, a lifting frame 2, a bottom sleeve 3, a central rod 4, a receiving plate 5, a pressure plate 6, a spring 7, an internal rod 8, and a locking mechanism. The moving mechanism is connected to the support frame 1 and the lifting frame 2. The bottom sleeve 3 is installed on the lower end face of the lifting frame 2. The internal rod 8 is slidably connected inside the bottom sleeve 3. The central rod 4 is coaxially installed on the internal rod 8, and the pressure plate 6 is installed on the central rod 4, pressing against the receiving plate 5. The receiving plate 5 is slidably connected to the central rod 4. A spring 7 is sleeved on the central rod 4, with one end of the spring 7 abutting against the receiving plate 5 and the other end abutting against the lifting frame 2. The locking mechanism is installed on the bottom sleeve 3 and includes an inclined sleeve 9 and a slider 10. The inclined sleeve 9 is installed on the inner wall of the bottom sleeve 3, and the slider 10 is... Multiple sliders 10 are slidably connected within the inclined sleeve 9. Each slider 10 has a locking block 11, and each locking block 11 has a one-way block 12. Multiple one-way sleeves 13 are equidistantly arranged on the internal rod 8. The one-way blocks 12 are locked onto the one-way sleeves 13. A pull rope 14 and a return spring 15 are provided on the lower end face of the locking block 11. The pull rope 14 is located inside the return spring 15, and the return spring 15 abuts against the bottom sleeve 3. A pull sleeve 16 is provided on the pull rope 14, and multiple guide rods 17 are provided on the pull sleeve 16. A guide hole 18 is opened on the lower end face of the bottom sleeve 3, and the guide rods 17 are slidably connected within the guide hole 18.

The moving mechanism includes a moving frame 20 and a plate maker 21. The moving frame 20 is mounted on the support frame 1, and the plate maker 21 is mounted on the support frame 1. The printing plate is placed on the receiving plate 5.

[0029] In this embodiment, when the receiving plate 5 needs to be replaced for different situations, the current receiving plate 5 is first released. Pulling the pull sleeve 16 will cause multiple pull ropes 14 to move downwards. Since the locking block 11 is connected to the pull ropes 14, the slider 10 will slide along the inclined sleeve 9. Since the one-way block 12 is locked on the one-way sleeve 13, it will cause the internal rod 8 to slide downwards. The one-way block 12 is in a state of sliding downwards while expanding. Then, the connection with the internal rod 8 is released, so the central rod 4 can be pulled out. Then, the corresponding receiving plate 5 is replaced. When fixing the central rod 4, simply insert the central rod 4 into the bottom sleeve 3, and then the one-way block 12 is locked on the one-way sleeve 13, thus completing the locking process. After the receiving plate 5 is fixed, the corresponding printing plate is placed on the receiving plate 5, and then the plate maker 21 is moved by the moving frame 20, completing the plate-making process through the plate maker 21.

[0030] In summary, when using the device, if the receiving plate 5 needs to be replaced for different situations, first disconnect the current receiving plate 5. First, pull the pull sleeve 16, which will drive multiple pull ropes 14 to move downwards. Since the locking block 11 is connected to the pull rope 14, the slider 10 will slide along the inclined sleeve 9. Since the one-way block 12 is locked on the one-way sleeve 13, it will drive the internal rod 8 to slide downwards. The one-way block 12 is in a state of sliding downwards and expanding at the same time. Then disconnect the connection with the internal rod 8, so the center rod 4 can be pulled out. Then replace the corresponding receiving plate 5. When fixing the center rod 4, simply insert the center rod 4 into the bottom sleeve 3, and then the one-way block 12 is locked on the one-way sleeve 13, thus completing the locking process. After the receiving plate 5 is fixed, place the corresponding printing plate on the receiving plate 5, and then move the plate maker 21 through the moving frame 20. The plate maker 21 completes the plate making process.
