[0002] Computer-to-plate (CTP) plates are aluminum-based sheets pre-coated with a photosensitive layer and are a core consumable in the modern printing industry. After production, they are usually in rolls or large-format sheets and cannot be used directly on the printing press. They must be cut to a fixed length according to the specific specifications of the printing press and the size of the job to obtain the precise size required for final printing.

[0003] Current cutting operations largely rely on a combination of manual measurement and semi-automatic mechanical cutting. Operators must manually measure and draw lines and operate a guillotine cutter or table saw to cut, which introduces significant human error, resulting in inconsistent cutting lengths and affecting printing registration accuracy. Furthermore, this method is inefficient and labor-intensive. Summary of the Invention

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-6 The CTP plate length cutting machine includes a drive mechanism 1, a support platform 2 on one side of the drive mechanism 1, a clamping mechanism 3 and a cutting mechanism 4 on the upper part of the support platform 2, a conveyor 5 on one side of the support platform 2, a length adjustment mechanism 6 on the upper part of the conveyor 5, and a controller 8 fixed on the surface of the support platform 2.

[0024] The drive mechanism 1 includes two support plates 101. An active roller 102 is rotatably connected to the surface of the support plate 101. An extension plate 103 is fixed to the surface of one side of the support plate 101. A drive motor 104 is fixed to the surface of the extension plate 103. The output shaft of the drive motor 104 is fixedly connected to one end of the active roller 102. A sliding groove is opened on the surface of the support plate 101. A sliding block 105 is slidably connected to the surface of the sliding groove. A driven roller 107 is rotatably connected between the two sliding blocks 105. A first cylinder 106 is fixed to the top of the support plate 101. The piston rod of the first cylinder 106 is fixedly connected to the top of the sliding block 105.

[0025] Through the above technical solution, the drive motor 104 starts, driving the active roller 102 to rotate. At the same time, the piston rod of the first cylinder 106 extends, pushing the sliding block 105 down along the slide groove, thereby causing the driven roller 107 to press down synchronously, clamping the plate together with the active roller 102. The plate is then transported towards the support platform 2 by friction. After the transport is completed, the piston rod of the first cylinder 106 retracts, the driven roller 107 lifts up, and the clamping of the plate is released, so as to carry out subsequent positioning and cutting operations. The driven roller 107 driven by the first cylinder 106 can realize the rapid application and release of clamping force. The clamping force is large and stable, effectively preventing the plate from slipping during the transport process and ensuring the reliability of the transport. At the same time, this structure has good adaptability to changes in plate thickness. Different specifications of plates can be adapted by adjusting the cylinder pressure, making it highly versatile.

[0026] The clamping mechanism 3 includes a first bracket 301, a second cylinder 302 fixed to the top of the first bracket 301, the piston rod of the second cylinder 302 passing through the first bracket 301 and fixedly connected to the mounting plate 303 through a floating joint, and a flexible clamping plate 304 fixed to the bottom of the mounting plate 303. The flexible clamping plate 304 is made of polyurethane.

[0027] Through the above technical solution, after the plate is conveyed to the cutting station, the piston rod of the second cylinder 302 extends, pushing the mounting plate 303 and the flexible clamping plate 304 downward until the flexible clamping plate 304 presses against the surface of the plate. At this time, the cylinder maintains pressure, firmly fixing the plate to the support platform 2 during the cutting process to prevent it from moving or vibrating. After the cutting is completed, the piston rod of the second cylinder 302 retracts, driving the flexible clamping plate 304 to lift and release the fixation. The pressing method of the second cylinder 302 and the flexible clamping plate 304 can provide a strong and uniform pressing force, eliminating the displacement of the plate during cutting and ensuring cutting accuracy. The flexible clamping plate 304 is made of polyurethane, which is soft and wear-resistant. It can provide sufficient friction without damaging or scratching the delicate photosensitive coating of the CTP plate, effectively protecting product quality.

[0028] The cutting mechanism 4 includes a second bracket 401, a third cylinder 402 fixed on the top of the second bracket 401, the piston rod of the third cylinder 402 passing through the second bracket 401 and a first linear module 403 fixed thereon, a cutting motor 404 fixed on the surface of the moving part of the first linear module 403, a saw blade 405 mounted on the output shaft of the cutting motor 404, and a through groove 7 for the saw blade 405 to pass through on the surface of the support platform 2.

[0029] Through the above technical solution, the piston rod of the third cylinder 402 first extends, driving the entire first linear module 403 and the cutting motor 404 to descend to the preset cutting depth. Then, the cutting motor 404 starts and drives the saw blade 405 to rotate at high speed. At the same time, the first linear module 403 starts working, driving the rotating saw blade 405 to move smoothly along the preset path, thereby completing the cutting of the board. After the cutting is completed, the first linear module 403 resets, the saw blade 405 stops rotating, and finally the piston rod of the third cylinder 402 retracts, so that the saw blade 405 is completely separated from the board and the through groove 7. The through groove 7 on the support platform 2 provides unobstructed passage space for the saw blade 405, realizing complete cutting and avoiding board material sticking or cutting the platform.

[0030] The fixed length adjustment mechanism 6 includes a third support 601, a second linear module 602 is fixed below the surface of the third support 601, a fourth cylinder 603 is fixed on the surface of the moving part of the second linear module 602, and a baffle 604 is fixed on the piston rod of the fourth cylinder 603.

[0031] Through the above technical solution, the controller 8 controls the moving part of the second linear module 602 to be precisely positioned according to the set cutting length, thereby driving the baffle 604 on it to move to the target position, serving as a mechanical limit for the front end conveying of the sheet material.

[0032] A pressure sensor 605 is fixed on the surface of the baffle 604.

[0033] Through the above technical solution, when the plate moves forward under the action of the drive mechanism 1 and contacts the baffle 604, it will generate a certain pressure on the baffle 604. This pressure is detected in real time by the pressure sensor 605 and converted into an electrical signal and transmitted to the controller 8. When the pressure value reaches the preset threshold, the controller 8 determines that the plate has been accurately positioned and then issues a command to stop the drive mechanism 1 and start the clamping mechanism 3 to press it.

[0034] Four first guide rods 305 slide through the surface of the first bracket 301, and the bottom ends of the first guide rods 305 are fixedly connected to the four top corners of the mounting plate 303 respectively.

[0035] With the above technical solution, when the second cylinder 302 drives the mounting plate 303 to move up and down, the four first guide rods 305 slide synchronously in the guide holes of the first bracket 301, ensuring that the mounting plate 303 and the flexible clamping plate 304 can only perform strictly vertical lifting and lowering movements.

[0036] Two second guide rods 406 slide through the surface of the second bracket 401, and the bottom of the second guide rods 406 are fixedly connected to the top of the first linear module 403.

[0037] With the above technical solution, when the third cylinder 402 drives the first linear module 403 and the cutting component to move up and down as a whole, the two second guide rods 406 slide synchronously in the guide holes of the second bracket 401, providing additional support and guidance for the entire lifting component.

[0038] Working principle: First, the drive motor 104 starts, and simultaneously the first cylinder 106 pushes the driven roller 107 downward, which, together with the drive roller 102, clamps the plate and smoothly conveys it onto the support platform 2. At the same time, the fixed-length adjustment mechanism 6, according to the cutting length set by the controller 8, precisely moves the baffle 604 to the target position via the second linear module 602. When the front end of the plate contacts the baffle 604 under the conveying force and triggers the pressure sensor 605, the drive mechanism 1 stops, and the conveying stage is completed. Immediately afterwards, the clamping mechanism 3 actuates, and the second cylinder 302 pushes the mounting plate 303 and its bottom flexible clamping plate 304 downward. Utilizing the soft properties of polyurethane material, it provides a huge clamping force while clamping the plate surface without damage, firmly fixing it onto the support platform 2. After fixing... After completion, the cutting mechanism 4 is activated. The third cylinder 402 first pushes the entire assembly containing the saw blade 405 downwards to the set cutting depth. Then, the cutting motor 404 starts, driving the saw blade 405 to rotate at high speed. Simultaneously, the first linear module 403 works, driving the rotating saw blade 405 to move smoothly along a straight line, completely cutting the board. The through groove 7 on the support platform 2 ensures that the saw blade 405 can completely cut the board. After cutting, the saw blade 405 of the cutting mechanism 4 stops and is lifted and reset. Then, the flexible clamping plate 304 of the clamping mechanism 3 is lifted to release the fixation. The fourth cylinder 603 is simultaneously reset upwards. Finally, the conveyor 5 starts, moving the cut finished board out of the working area, thus completing a complete work cycle. After that, the equipment automatically enters the next cycle until the set processing quantity is completed. This equipment realizes full automation from feeding, fixed length positioning, clamping and fixing, precise cutting to automatic unloading, effectively solving the core problems of traditional methods that rely on manual labor, have poor accuracy, and low efficiency. It has significant benefits in terms of high automation, high precision, and high efficiency.
