Description

Technical Field

[0001] This utility model belongs to the field of CTP plate-making machine technology, and in particular relates to a paper plate separation device for a CTP plate-making machine. Background Technology

[0002] CTP (Continuous Phototransfer) plate-making machines are intelligent devices that directly output digital files to printing plates using laser imaging technology. Their core working principle involves using laser light sources of different wavelengths (such as 405nm violet laser and 830nm infrared laser) to precisely expose metal or polyester plates coated with a photosensitive layer. The main structure includes an automatic plate feeding system, a precision optical imaging unit, a temperature control system, and a dust removal device. High-end models also integrate an online quality inspection module. The paper plate separation device in a CTP plate-making machine primarily separates the paper plate from the backing paper, preventing the backing paper from entering the CTP plate-making machine and causing operational jams.

[0003] Comparing with Chinese Patent No. CN218507127U, an environmentally friendly paper plate separation device for a CTP plate-making machine is disclosed. This device includes a horizontal moving mechanism with a lifting mechanism mounted on it. A support plate is connected to the lifting mechanism, and a mounting plate is fixed to the bottom of the support plate. Buffer components are evenly spaced at the bottom of the mounting plate, and vacuum suction cups are connected to the bottom of the buffer components. A vibration separation mechanism is located on the front side of the mounting plate. The vibration separation mechanism includes an L-shaped mounting base with a vibration motor mounted on its front side and arc-shaped elastic sheets evenly spaced at the bottom. By incorporating this vibration separation mechanism, when the paper plate is sucked up, the vibration motor drives the arc-shaped elastic sheets to vibrate. The vibration of the arc-shaped elastic sheets strikes the paper plate, causing the backing paper adsorbed on the paper plate to fall off and separate, thus improving the paper plate separation efficiency during the plate-making machine's operation.

[0004] However, the aforementioned patents lack initiative and can only passively wait for the liner paper to separate from the paperboard, making it difficult to guarantee the completeness of the liner paper separation. At the same time, the lack of external discharge of the liner paper seriously affects the subsequent adsorption of the paperboard. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a paper plate separation device for a CTP plate-making machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0017] 3. Through the coordinated operation of the feeding assembly, frame assembly and dispensing assembly, the entire process of paperboard conveying, positioning, separation and backing paper discharge is automated, reducing manual intervention;

[0018] 4. The limit slide can be slidably adjusted and locked to adapt to different sizes of paperboard and backing paper stacks, improving the equipment's versatility; the rotary separating roller and guide plate are driven by electric push rods and motors, and can be flexibly raised, lowered and rotated to accurately separate the adhered backing paper.

The limiting slide 107 slides along the support platform 102, the positioning position is adjusted, and the locking nail 108 is tightened to fix it. Multiple sets of paperboards and backing paper are stacked on the support platform 102, so that the ends are tightly attached to the limiting slide 107 for positioning. The vacuum suction cup 306 pulls the paperboard end into the space between the feeding roller 104 and the support platform 102 and then releases it. The frame body 101 supports the first motor 105 to drive the feeding roller 104 to rotate and push the paperboard to move and feed. The clearance groove 103 is used to avoid the material distribution component, and at the same time guides the backing paper to flow into the discharge groove 106 for cleaning.

[0029] In this embodiment: the feeding assembly includes a translation mechanism for reciprocating movement. Two telescopic cylinders 304 are symmetrically installed in the middle of the translation mechanism. A lifting frame 305 is installed between the telescopic ends of the telescopic cylinders 304. Several vacuum suction cups 306 are evenly distributed on the lifting frame 305. The translation mechanism includes two symmetrically arranged linear guide rails 301. A linear motor 302 is installed on the linear guide rails 301. A translation frame 303 is installed between the linear motors 302. The translation frame 303 first supports the telescopic cylinders 304 to extend and retract, pushing the lifting frame 305 to drive the vacuum suction cups 306 to move up and down. The vacuum suction cups 306 adsorb one end of the paperboard or backing paper. Then, the linear motor 302 drives the translation frame 303 to move along the linear guide rails 301, pulling the paperboard or backing paper to move.

[0030] In this embodiment: the material distribution assembly includes a discharge mechanism for lifting and guiding the discharge of the backing paper, and a rotary separation mechanism for rotating and separating the paperboard and the backing paper is provided on one side of the discharge mechanism; the discharge mechanism includes a guide plate 201, and two connecting seats 202 are symmetrically arranged at both ends of the bottom of the guide plate 201, and electric push rods 203 are installed on the connecting seats 202; the rotary separation mechanism includes a symmetrically arranged swing frame 204, a rotary separation roller 206 is installed at one end of the swing frame 204, a second motor 207 is provided at one end of the rotary separation roller 206, and a third motor 205 is provided at the end of the swing frame 204 away from the rotary separation roller 206; the rotary separation roller 206 is a uniformly distributed multi-roller structure, and the swing frame 204 is a symmetrical double-long plate structure; when the paperboard moves across the clearance groove 103, the third motor 205 drives... The rotating frame 204 rotates, lifting the rotary separating roller 206 to the lower surface of the paperboard. Then, the second motor 207 drives the rotary separating roller 206 to rotate and rub against the lower surface of the paperboard. If there is any liner paper adhering to it, the liner paper is pushed back to its original position. When the liner paper moves to the clearance groove 103, the electric push rod 203 retracts and pulls the guide plate 201 upward through the connecting seat 202. At the same time, the third motor 205 drives the rotating frame 204 to rotate, lifting the rotary separating roller 206 to the lower surface of the liner paper. Then, the second motor 207 drives the rotary separating roller 206 to rotate forward first to prevent the lower surface of the liner paper from adhering to the second paperboard, and then rotates in reverse to rub against the liner paper and move forward. At the same time, the vacuum suction cup 306 releases the liner paper, so that the liner paper enters the clearance groove 103 under the guidance of the guide plate 201 and flows into the discharge groove 106.

[0031] Working principle: The sliding limit slide 107 along the support platform 102 is adjusted to the positioning position and the locking nail 108 is tightened to fix it. Multiple sets of paperboards and backing paper are stacked on the support platform 102, so that the ends are tightly positioned against the limit slide 107. When feeding into the CTP plate-making machine, the translation frame 303 first supports the telescopic cylinder 304 to extend and retract, pushing the lifting frame 305 to drive the vacuum suction cup 306 to move up and down. The vacuum suction cup 306 adsorbs one end of the paperboard, and the linear motor 302 then drives... The movable translation frame 303 moves along the linear guide rail 301, pulling the paperboard across the clearance groove 103. During this process, the third motor 205 drives the swing frame 204 to rotate, lifting the rotary roller 206 to the lower surface of the paperboard. Then, the second motor 207 drives the rotary roller 206 to rotate and rub against the lower surface of the paperboard. If there is any liner paper adhering to it, the liner paper is pushed out and the paperboard is pushed back to its original position. Then, the vacuum suction cup 306 pulls the end of the paperboard and inserts it between the feeding roller 104 and the support table 102. Release, the frame 101 supports the first motor 105 to drive the feeding roller 104 to rotate and push the paperboard to move for feeding. After feeding is completed, the third motor 205 drives the rotary separating roller 206 to reset, and the linear motor 302 drives the vacuum suction cup 306 to reset and suction one end of the liner paper. Then, the liner paper is pulled to move to the clearance groove 103. At this time, the electric push rod 203 retracts and pulls the guide plate 201 to rise through the connecting seat 202. At the same time, the third motor 205 drives the swing frame 204 to rotate, lifting the rotary separating roller 206 to the lower surface of the liner paper. Then, the second motor 207 drives the rotary separating roller 206 to rotate forward first to avoid the second paperboard adhering to the lower surface of the liner paper, and then rotates in reverse to rub the liner paper forward. At the same time, the vacuum suction cup 306 releases the liner paper, so that the liner paper enters the clearance groove 103 under the guidance of the guide plate 201 and flows into the discharge groove 106 to wait for cleaning. Finally, the above steps are repeated to ensure the separation and feeding of the paperboard of the CTP plate making machine.
