Description

Technical Field

[0001] This utility model belongs to the technical field of plate-making equipment, and specifically relates to a roller cleaning structure for a CTP plate-making machine. Background Technology

[0002] CTP (Cyclic Plate Making) machines are advanced prepress devices integrating precision optical, electrical, and mechanical systems. The rotary roller is its core component, responsible for supporting the printing plate, transmitting laser energy, and ensuring scanning accuracy. The roller is typically made of high-quality metal or alloy to ensure good rigidity and wear resistance. Simultaneously, the roller surface undergoes precision machining and treatment to achieve the required flatness and smoothness, ensuring that the laser beam does not affect plate quality due to printing plate movement or deformation during scanning. The CTP roller cleaning structure is a key component in ensuring plate quality and extending the equipment's lifespan. This cleaning structure is typically designed to be both efficient and environmentally friendly, effectively removing chemical stains and other impurities from the roller.

[0003] Announcement No. "CN219292235U" discloses a roller cleaning structure for a plate-making machine, comprising an adjacent plate-making machine body and a cleaning support frame, a controller, a drying mechanism, and a cleaning tank mounted on the cleaning support frame, a publishing support frame mounted on one side of the plate-making machine body, and a rotary drive mechanism for driving the publishing support frame to rotate. The cleaning tank contains multiple ultrasonic generators, and the publishing support frame contains multiple rollers. The rotary drive mechanism drives the publishing support frame to rotate into the cleaning tank, and the drying mechanism dries the cleaned publishing support frame. The rotary drive mechanism, ultrasonic generators, and drying mechanism are all electrically connected to the controller. This invention can clean and dry the rollers without causing pollution to the working environment, shortens the cleaning time of the rollers, and improves the working efficiency of the rollers.

[0004] Although the above-mentioned utility model can clean and dry the rollers without causing pollution to the working environment, shorten the cleaning time of the rollers, and improve the working efficiency of the rollers, when the ultrasonic generator cleans the rollers, it will generate tiny bubbles. When these bubbles burst, they will generate a strong impact force to remove stains from the roller surface. However, if this impact force is too strong or lasts too long, it will cause physical damage to the roller surface. Moreover, rollers of different materials have different adaptability to ultrasonic cleaning, and the expected cleaning effect cannot be achieved. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a roller cleaning structure for CTP plate making machine, so as to solve the problem that when the ultrasonic generator cleans the roller, the bursting of bubbles generates a strong impact force. If the impact force is too strong or lasts for too long, it will cause physical damage to the roller surface. Moreover, the adaptability of rollers made of different materials to ultrasonic cleaning is different, and the expected cleaning effect cannot be achieved.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A rotary roller cleaning structure for a CTP plate-making machine includes a support frame, with rotary rollers symmetrically and rotatably connected at equal intervals inside the support frame. The other end of each rotary roller extends out of the support frame and is fixedly connected to a driven gear. A first drive motor is mounted on one side of the support frame, and a drive gear is fixedly sleeved on the outer wall of the output shaft of the first drive motor. The driven gears mesh with each other, and the driven gear meshes with the drive gear. Cleaning rollers are symmetrically arranged at equal intervals inside the support frame, with connecting columns symmetrically and movably connected to both ends of each cleaning roller. A fixing component is installed inside each connecting column. A lifting seat is symmetrically arranged on one side of the support frame, and a second drive motor is mounted on the other side of the lifting seat. The output end of the second drive motor passes through the lifting seat and extends into the support frame, where it is fixedly connected to the rotating column. Lifting components are symmetrically installed on one side of the support frame.

[0008] The fixing assembly includes a cavity, a return spring, a movable block, a fixed block, a slider, and a sliding ring. A cavity is formed inside the connecting column. A return spring is fixedly connected to one side of the cavity, and a movable block is fixedly connected to the other end of the return spring. A fixed block is fixedly connected to the other side of the movable block. The other end of the fixed block extends out of one end of the connecting column. A slider is symmetrically fixedly connected to the outer wall of the movable block. The other end of the slider extends out of the outer side of the connecting column and is fixedly connected to a sliding ring. The sliding ring is slidably connected to the connecting column. A sliding groove is symmetrically formed on the outer wall of the connecting column, communicating with the cavity. The sliding groove and the slider are slidably connected. Fixed grooves are formed at both ends of the cleaning roller, and the fixed grooves are inserted into the fixed blocks. This allows users to select and replace the appropriate cleaning roller according to cleaning needs and the material of the roller, ensuring the cleanliness of the roller and improving plate-making quality. Furthermore, it ensures cleaning effectiveness while avoiding unnecessary damage to the roller surface.

[0009] As a preferred technical solution, the lifting assembly includes a lead screw, a third drive motor, a lifting plate, a sliding groove, a sliding block, and a guide rod. A fixed seat is symmetrically fixedly connected to one side of the support frame, and the lead screw is rotatably connected to the opposite end of the fixed seat. The third drive motor is installed at the bottom of the fixed seat, and its output end is fixedly connected to the lead screw. A lifting plate is sleeved on the outside of the lead screw, and a connecting rod is symmetrically fixedly connected to the upper end of the lifting plate. The other end of the connecting rod is fixedly connected to the lifting seat. A sliding groove is opened on one side inside the support frame, and a guide rod is fixedly connected inside the sliding groove. A sliding block is sleeved on the outside of the guide rod, and the other end of the sliding block is rotatably connected to the connecting column. The lifting plate and the lead screw are threadedly connected, the guide rod and the sliding block are slidably connected, and the sliding block and the sliding groove are slidably connected. This allows the user to precisely adjust the position of the cleaning roller according to the actual position and height of the rotating roller, ensuring a tight fit between the cleaning roller and the rotating roller surface. This precise positioning helps to more effectively remove stains and residues from the rotating roller surface, improving the cleaning effect.

[0010] As a preferred technical solution, the support frame is symmetrically provided with guide grooves on one side, and the lifting plate is symmetrically fixedly connected with guide blocks at one end. The guide blocks and guide grooves are slidably connected. The sliding cooperation between the guide blocks and guide grooves provides stable guidance for the lifting and lowering of the cleaning roller, effectively preventing the cleaning roller from deviating or shaking, and ensuring that the cleaning roller can accurately reach the predetermined position, thereby improving the accuracy and efficiency of cleaning.

[0011] In summary, the present invention has the following main advantages:

[0012] Firstly, in this utility model, pushing the sliding ring causes the slider to move the movable block and the fixed block. The movable block presses against the return spring, compressing the return spring. At the same time, the fixed block retracts into the cavity. Then, according to the material of the rotating roller and the cleaning requirements, the appropriate cleaning roller is placed at the opposite end of the connecting column. The sliding ring is released, the return spring returns to its original position, and the movable block rebounds, causing the fixed block to pop out and insert into the fixing groove, thus completing the installation of the cleaning roller. This allows users to select and replace the appropriate cleaning roller according to the cleaning requirements and the material of the rotating roller, ensuring the cleanliness of the rotating roller and thus improving the plate-making quality. Moreover, it can ensure the cleaning effect while avoiding unnecessary damage to the surface of the rotating roller.

[0013] Secondly, in this utility model, the third drive motor is started to control the lead screw to rotate. The lead screw rotates with the lifting plate, thereby controlling the lifting plate to descend. The lifting plate drives the lifting seat and the second drive motor to descend through the connecting rod. At the same time, the lifting seat drives the cleaning roller to descend. The cleaning roller drives the sliding block at the other end to slide outside the guide rod, so that the surface of the cleaning roller is in contact with the surface of the rotating roller. The second drive motor is started to clean the rotating roller. This allows the user to accurately adjust the position of the cleaning roller according to the actual position and height of the rotating roller, ensuring that the cleaning roller is in close contact with the surface of the rotating roller. This precise positioning helps to more effectively remove stains and residues from the surface of the rotating roller and improve the cleaning effect. Attached Figure Description
