[0001] The invention belongs to the technical field of printing, and in particular relates to a CTP plate scrapping machine and a scrapping method thereof. Background Art

[0002] CTP plates are materials used for printing platemaking and are categorized into photosensitive CTP plates, high-sensitivity resin plates, and ultraviolet laser CTP plates. Applications include commercial printing, newspaper printing, and packaging printing, such as books, magazines, posters, and brochures. They meet the demands of high-quality, high-precision printing, providing sharp images and delicate colors. They enable rapid platemaking, meeting the daily high-volume printing demands of newspapers while ensuring consistent print quality. For packaging products like boxes and bags, CTP plates enable high-resolution graphics and text printing, enhancing the aesthetics and quality of the packaging.

[0003] The characteristics of CTP plates are improved printing quality: it eliminates the intermediate film link, reduces distortion and errors in the image transfer process, improves the image restoration rate, and can better reproduce the details and colors of the original. Improve work efficiency: directly output from the computer to the printing plate, without the need for tedious steps such as making film and film platemaking, which greatly shortens the platemaking time and improves work efficiency. It is especially suitable for printing short runs and expedited orders. Reduce costs: It reduces the use of materials such as film, developer, and fixer, and also reduces the scrap rate generated in the film platemaking process, thereby reducing printing costs. Environmental protection and energy saving: The waste liquid and waste gas generated in the platemaking process of CTP plates are relatively small, and the pollution to the environment is relatively small, which meets environmental protection requirements.

[0004] Currently, CTP plates are sold in whole sheets. If used CTP plates are not scrapped, they may flow into the market for secondary use. Summary of the Invention

[0005] The purpose of the present invention is to provide a CTP board scrapping machine and a scrapping method thereof in order to solve the above-mentioned technical problems, thereby achieving the effect of eliminating the secondary utilization of TCP boards.

[0006] In view of this, the present invention provides a CTP board scrapping machine, comprising a frame, a feed port and a discharge port being provided on the frame, and a device located between the feed port and the discharge port and rotating up and down relative to each other is provided: A needle roller, comprising a smooth circular shaft and needles arranged on the outer circumference of the smooth circular shaft; An optical axis is rotatably arranged below the needle roller, and a plate passage for allowing the CTP plate to pass through is provided between the needle roller and the optical axis; In this technical solution, the CTP board passes between the optical axis and the needle roller, and the needles of the needle roller will insert many holes in the CTP board, thereby scrapping the CTP board and preventing the TCP board from being reused.

[0007] Furthermore, a cleaning assembly for cleaning the needles of the needle roller is correspondingly provided on the side of the needle roller.

[0008] In this technical solution, when the needle with a needle roller is used to puncture the CTP board, some of the debris will adhere to the needle. If too much debris accumulates, it will affect the subsequent puncturing. The cleaning component can be used to clean the debris from the needle in time to ensure long-term puncturing quality.

[0009] Furthermore, the cleaning component includes a brush, both ends of the brush are fixedly arranged, and the brush is flexible.

[0010] In this technical solution, the needle roller causes the needles to pass through the brush during the rotation process, and the round roller brush can brush off the debris on the needles.

[0011] Furthermore, a debris outlet is provided below the optical axis, and a round roller brush is provided directly below and in contact with the optical axis. Both ends of the round roller brush are fixedly connected, and the surface of the round roller brush is sticky.

[0012] In this technical solution, most of the pierced debris will fall from the optical axis to the debris outlet, but a small amount of debris will remain on the optical axis. By setting a round roller brush that is attached to the optical axis and has a sticky surface, the debris retained on the optical axis can be taken away. The stickiness on the surface of the round roller brush is a layer of sticky glue, which is applied on the non-woven fabric. The non-woven fabric is surrounded by the round roller brush and fixed by Velcro. When it needs to be replaced, just tear off the Velcro and replace the non-woven fabric.

[0013] Furthermore, the frame is also provided with a hole cleaning component, which is used to clean the debris retained in the hole of the CTP board after the CTP board is punctured by the needle.

[0014] Furthermore, the hole cleaning component includes: A hole cleaning seat, which is fixedly arranged on the frame near the discharge port; A hole cleaning motor, wherein the hole cleaning motor is fixedly arranged on the hole cleaning seat; The swivel seat includes a first core shaft and a second core shaft parallel to each other, both ends of the first core shaft are rotatably arranged on the hole cleaning seat, and the first core shaft and the second core shaft are connected by a first connecting plate; a second connecting plate, one end of which is fixedly connected to the output end of the hole cleaning motor, and the other end of which is provided with a sliding hole; A sliding rod, one end of which is cylindrical and slidingly sleeved in the sliding hole, and the other end of which is slidingly arranged on the outer periphery of the second core shaft; The hole cleaning soft rod has one end fixed on the first core shaft, is arranged perpendicular to the moving direction of the CTP plate, and is made of plastic material and is flexible.

[0015] In this technical solution, after the needle punctures the holes, some holes still have debris that has been punctured and has not fallen off. If it is not removed in time, the debris in the holes will fall everywhere during the subsequent transportation and transfer of the CTP board, affecting the cleanliness. Therefore, the pre-set hole cleaning component can effectively remove the punctured debris retained in the hole. The working process of the hole cleaning component is that the hole cleaning motor starts, drives the second connecting plate to rotate, and drives the sliding rod to slide in the sliding hole and slide on the second core shaft along the length direction of the second core shaft, and drives the swivel seat to swing around the axis of the first core shaft, so that the hole cleaning soft rod swings and hits the CTP board, and the vibration force causes the debris in the hole of the CTP board to fall off.

[0016] Furthermore, a burr removal component is provided below the CTP plate.

[0017] In this technical solution, by providing a burr removal component, the burrs and flanges generated by needle punctures on the bottom of the CTP board can be removed to prevent injuries to people during subsequent transportation and handling.

[0018] Furthermore, the burr removal assembly includes: A dehairing plate is provided below the CTP plate and is perpendicular to the moving direction of the CTP plate, with the upper end of the dehairing plate abutting against the lower end of the CTP plate; A fixing frame, the fixing frame is fixedly arranged in the frame, and the dehairing plate is slidably arranged on the fixing frame; A dehairing motor, the dehairing motor being fixedly arranged between the optical axis and the hole cleaning component in the frame; A turntable, the turntable being fixedly connected to an output end of the hair removal motor; A connecting rod, one end of which is hinged to a non-center portion of the rotating disk, and the other end of which is hinged to the lower end of the dehairing plate.

[0019] In this technical solution, the deburring motor is started, causing the turntable to rotate, and the connecting rod to move so that the deburring plate slides back and forth in the fixed frame along the moving direction perpendicular to the CTP plate. The deburring plate is made of steel and is relatively hard. During the reciprocating sliding process, the burrs and flanges below the holes on the CTP plate will be scraped off.

[0020] Furthermore, the scrapping method includes the following steps: S1: The CTP plate is fed into the scrapping machine from the feed port and inserted between the needle roller and the optical axis. The scrapping machine is started to rotate the needle roller and the optical axis, so that the CTP plate continues to slide toward the discharge port, and the needle roller punches holes in the CTP plate. S2: The burr removal component removes the burrs and flanges on the bottom of the CTP plate caused by the needle puncture through the reciprocating sliding of the deburring plate under the CTP plate; S3: The hole cleaning component removes the debris retained in the hole of the CTP board after the CTP board is punctured by the needle through the reciprocating movement of the hole cleaning soft rod above the CTP board.

[0021] The beneficial effects of the present invention are: 1. The CTP board passes between the optical axis and the needle roller. The needles of the needle roller will insert many holes in the CTP board, thereby scrapping the CTP board and preventing the TCP board from being reused. 2. The needle roller rotates so that the needles pass through the brush, and the round roller brush can brush off the debris on the needles; 3. The round roller brush can remove the debris left on the optical axis; 4. Pre-setting the hole cleaning component can effectively remove the debris trapped in the hole, preventing the debris in the hole from falling everywhere during the subsequent transportation and transfer of the CTP board, ensuring cleanliness.
