Description

Technical Field

[0001] This utility model belongs to the field of printing technology, and in particular relates to a CTP board scrapping machine. Background Technology

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

[0003] The advantages of CTP plates include: improved printing quality: eliminating the intermediate film step reduces distortion and errors during image transfer, improves image fidelity, and better reproduces the details and colors of the original artwork. Increased work efficiency: direct output from the computer to the printing plate eliminates the need for film fabrication and exposure, significantly shortening plate-making time and improving efficiency, making it particularly suitable for short-run jobs and rush orders. Reduced costs: reduced use of film, developer, and fixer, as well as lower scrap rates from film exposure, thus reducing printing costs. Environmental friendliness and energy conservation: CTP plate-making generates relatively less waste liquid and exhaust gas, resulting in less environmental pollution and meeting environmental protection requirements.

[0004] Currently, CTP boards are sold in whole sheets. If used CTP boards are not disposed of properly, they may enter the market for reuse. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a CTP board scrapping machine, thereby eliminating the need for secondary use of TCP boards.

[0006] In view of this, the present invention provides a CTP board scrapping machine, including a frame, a base frame having an inlet and an outlet, and a component rotatably arranged between the inlet and outlet.

[0007] A needle roller, comprising a smooth circular shaft and needles arranged on the outer circumferential surface of the smooth circular shaft;

[0008] The optical axis is rotatably positioned below the needle roller, and a through-board channel is provided between the needle roller and the optical axis to allow the CTP board to pass through;

[0009] In this technical solution, the CTP board passes between the optical axis and the needle roller. The needle roller will make many holes in the CTP board to scrap the CTP board and prevent the secondary use of the TCP board.

[0010] Furthermore, a cleaning component for cleaning the needles on the needle roller is provided on the side of the needle roller.

[0011] In this technical solution, when the needle roller pierces the CTP plate, some of the debris will adhere to the needle. If there is too much accumulation, it will affect the subsequent piercing. The cleaning component can clean the debris from the needle in time to ensure long-term piercing quality.

[0012] Furthermore, the cleaning component includes a brush with both ends fixedly disposed and the brush being flexible.

[0013] In this technical solution, the needle roller rotates so that the needle passes through the brush, and the circular roller brush can brush off the debris on the needle.

[0014] Furthermore, a debris outlet is provided below the optical axis, and a circular roller brush is provided directly below and attached to the optical axis. The two ends of the circular roller brush are fixedly connected, and the surface of the circular roller brush is sticky.

[0015] In this technical solution, most of the debris that is punctured will fall from the optical axis to the debris outlet. However, a small amount of debris will remain on the optical axis. By setting a circular roller brush that is attached to the optical axis and has an adhesive surface, the debris remaining on the optical axis can be removed. The adhesive on the surface of the circular roller brush is a layer of adhesive glue, which is applied to a non-woven fabric. The non-woven fabric is wrapped around the circular roller brush and fixed with Velcro. When it needs to be replaced, the Velcro can be torn off and the non-woven fabric replaced.

[0016] Furthermore, the frame is also equipped with a hole cleaning assembly, which is used to remove debris retained in the holes of the CTP plate after the CTP plate is punctured by a needle.

[0017] Furthermore, the hole cleaning assembly includes:

[0018] A hole-cleaning seat is fixedly mounted on the frame near the discharge port.

[0019] A hole-cleaning motor, which is fixedly mounted on a hole-cleaning seat;

[0020] The rotating base includes a first mandrel and a second mandrel that are parallel to each other. The two ends of the first mandrel are rotatably mounted on the cleaning seat. The first mandrel and the second mandrel are connected by a first connecting plate.

[0021] The second connecting plate has one end fixedly connected to the output end of the hole clearing motor, and the other end of the second connecting plate has a sliding hole.

[0022] A sliding rod, one end of which is cylindrical and slidably sleeved in a sliding hole, and the other end of which is slidably disposed on the outer periphery of the second mandrel;

[0023] The hole-cleaning flexible rod has one end fixedly mounted on the first mandrel and is perpendicular to the moving direction of the CTP plate. The hole-cleaning flexible rod is made of flexible plastic material.

[0024] In this technical solution, after the needle punctures the holes, some debris remains inside. If not removed in time, the debris inside the holes will fall everywhere during the subsequent transportation and transfer of the CTP board, affecting cleanliness. Therefore, a hole cleaning component can be pre-set to effectively remove the debris trapped inside the holes. The working process of the hole cleaning component is as follows: the hole cleaning motor starts, driving the second connecting plate to rotate, which slides the sliding rod in the sliding hole and slides along the length of the second spindle on the second spindle. The rotating seat swings around the axis of the first spindle, thereby causing the hole cleaning rod to swing and hit the CTP board. The vibration force causes the debris inside the holes of the CTP board to fall off.

[0025] Furthermore, a burr removal component is also provided below the CTP plate.

[0026] In this technical solution, by setting up a burr removal component, the burrs and edges caused by needle punctures on the bottom of the CTP board can be removed, preventing injury to people during subsequent transportation and handling.

[0027] Furthermore, the burr removal component includes:

[0028] A descaling plate is disposed below the CTP plate and perpendicular to the moving direction of the CTP plate, with the upper end of the descaling plate in contact with the lower end of the CTP plate.

[0029] A fixed frame is fixedly installed inside the machine frame, and the descaling plate is slidably installed on the fixed frame;

[0030] A dehairing motor, wherein the dehairing motor is fixedly mounted between the optical axis and the hole cleaning assembly inside the frame;

[0031] A turntable, which is fixedly connected to the output end of a dehairing motor;

[0032] A connecting rod, one end of which is hinged to a non-center point of the turntable, and the other end of which is hinged to the lower end of the deburring plate.

[0033] In this technical solution, the deburring motor is started, causing the turntable to rotate and move the connecting rod, so that the deburring plate slides back and forth in the fixed frame along the direction of movement perpendicular to the CTP plate. The deburring plate is made of steel, which is relatively hard. During the reciprocating sliding process, it will scrape off the burrs below the holes on the CTP plate.

[0034] Furthermore, the disposal method includes the following steps:

[0035] S1: Feed the CTP board into the scrapping machine from the feed port and insert it between the needle roller and the optical shaft. Start the scrapping machine to make the needle roller and the optical shaft rotate, so that the CTP board continues to slide towards the discharge port, and the needle roller punches holes in the CTP board.

[0036] S2: The deburring component removes the burrs and flanging caused by the needle punctures under the CTP plate by the reciprocating sliding of the deburring plate under the CTP plate.

[0037] S3: The hole cleaning assembly removes debris trapped inside the holes of the CTP plate after it has been punctured by a needle by reciprocating the hole cleaning rod above the CTP plate.

[0038] The beneficial effects of this utility model are:

[0039] 1. The CTP board passes between the optical axis and the needle roller. The needle roller will make many holes in the CTP board to scrap the CTP board and prevent the secondary use of the TCP board.

[0040] 2. During the rotation of the needle roller, the needle passes through the brush, and the round roller brush can brush off the debris on the needle;

[0041] 3. The circular roller brush can remove debris stuck on the optical axis;

[0042] 4. Pre-setting the hole cleaning component can effectively remove the debris stuck in the hole, preventing the CTP board from falling everywhere during subsequent transportation and transfer, thus ensuring cleanliness.

[0043] 5. The burr removal component can remove burrs and burrs caused by needle punctures on the underside of the CTP board, preventing injury to people during subsequent transportation and handling. Attached Figure Description

Additionally, features described with reference to certain examples may be combined in other examples.

[0057] Example 1:

[0058] like Figure 1-4 As shown, a CTP board 28 scrapping machine includes a frame 1, with an inlet 2 and an outlet 3 provided on the frame. Between the inlet 2 and the outlet 3, a component is rotatably mounted vertically relative to the component.

[0059] The needle roller 4 includes a smooth circular shaft and needles 5 arranged on the outer circumferential surface of the smooth circular shaft.

[0060] The optical axis 6 is rotatably positioned below the needle roller 4, and a through-board channel is provided between the needle roller 4 and the optical axis 6 to allow the CTP board 28 to pass through.

[0061] The CTP board 28 passes between the optical axis 6 and the needle roller 4. The needles 5 of the needle roller 4 will poke many holes in the CTP board 28 to scrap the CTP board 28 and prevent the TCP board from being reused.

[0062] A cleaning component is provided on the side of the needle roller 4 to clean the needles 5 on the needle roller 4. When the needles 5 on the needle roller 4 puncture the CTP plate 28, some of the debris will adhere to the needles 5. If too much debris accumulates, it will affect subsequent punctures. The cleaning component can remove the debris from the needles 5 in a timely manner to ensure long-term puncture quality.

[0063] The cleaning assembly includes a brush 7, which is fixed at both ends and is flexible. During rotation, the needle roller 4 causes the needle 5 to pass through the brush 7, and the circular roller brush 9 brushes off the debris from the needle 5. A debris outlet 8 is located below the optical axis 6, and the circular roller brush 9 is positioned directly below and in contact with the optical axis 6, with its two ends fixedly connected. The surface of the circular roller brush 9 is adhesive.

[0064] Most of the debris that is knocked off will fall from the optical axis 6 to the debris outlet 8, but a small amount of debris will remain on the optical axis 6. By setting a circular roller brush 9 that is attached to the optical axis 6 and has an adhesive surface, the debris remaining on the optical axis 6 can be removed. The adhesive on the surface of the circular roller brush 9 is a layer of sticky glue, which is applied to a non-woven fabric. The non-woven fabric is wrapped around the circular roller brush 9 and fixed with Velcro. When it needs to be replaced, simply tear off the Velcro and replace the non-woven fabric.

[0065] Example 2:

[0066] like Figure 2 and Figure 5 As shown, the frame 1 is also provided with a hole cleaning assembly 10, which is used to remove debris retained in the hole of the CTP plate 28 after the CTP plate 28 is punctured by the needle 5.

[0067] The hole cleaning assembly 10 includes:

[0068] Hole cleaning seat 11, the hole cleaning seat 11 is fixedly installed on the frame 1 near the discharge port 3;

[0069] Hole cleaning motor 12, which is fixedly mounted on hole cleaning seat 11;

[0070] Rotary seat 13, the rotary seat 13 includes a first spindle 14 and a second spindle 15 that are parallel to each other, the two ends of the first spindle 14 are rotatably mounted on the cleaning seat 11, and the first spindle 14 and the second spindle 15 are connected by a first connecting plate 16;

[0071] The second connecting plate 17 has one end fixedly connected to the output end of the hole clearing motor 12, and the other end of the second connecting plate 17 has a sliding hole 18.

[0072] The sliding rod 19 has one end in a cylindrical shape that is slidably sleeved in the sliding hole 18, and the other end of the sliding rod 19 is slidably disposed on the outer periphery of the second spindle 15.

[0073] The hole cleaning flexible rod 20 is fixed at one end on the first spindle 14. The hole cleaning flexible rod 20 is set perpendicular to the moving direction of the CTP plate 28. The hole cleaning flexible rod 20 is made of plastic and is flexible.

[0074] After the needle 5 punctures the holes, some debris remains inside. If not removed in time, the debris inside the holes will fall everywhere during the subsequent transportation and transfer of the CTP plate 28, affecting cleanliness. Therefore, the hole cleaning component 10 can effectively remove the debris stuck inside the holes. The working process of the hole cleaning component 10 is as follows: the hole cleaning motor 12 starts, driving the second connecting plate 17 to rotate, which slides the sliding rod 19 in the sliding hole 18 and slides along the length of the second spindle 15. The rotating seat 13 swings around the axis of the first spindle 14, thereby causing the hole cleaning soft rod 20 to swing and hit the CTP plate 28. The vibration force causes the debris inside the holes of the CTP plate 28 to fall off.

[0075] Example 3:

[0076] like Figure 2 and Figure 6 As shown, a burr removal component 22 is also provided below the CTP plate 28. By providing the burr removal component 22, the burrs and burrs caused by the punctures of the needles 5 on the bottom of the CTP plate 28 can be removed, preventing injury to people during subsequent transportation and handling.

[0078] De-scratching plate 23 is disposed below CTP plate 28 and perpendicular to the moving direction of CTP plate 28, with the upper end of de-scratching plate 23 in contact with the lower end of CTP plate 28.

[0079] The fixed frame 24 is fixedly installed inside the frame 1, and the descaling plate 23 is slidably installed on the fixed frame 24;

[0080] Hair removal motor 25, which is fixedly installed between optical axis 6 and hole cleaning assembly 10 inside frame 1;

[0081] Turntable 26, which is fixedly connected to the output end of the dehairing motor 25;

[0082] Link 27, one end of which is hinged to the non-center of turntable 26, and the other end is hinged to the lower end of deburring plate 23.

[0083] The deburring motor 25 starts, causing the turntable 26 to rotate, which moves the connecting rod 27 to make the deburring plate 23 slide back and forth within the fixed frame 24 along the direction of movement perpendicular to the CTP plate 28. The deburring plate 23 is made of steel and is relatively hard. During the back and forth sliding process, it will scrape off the burrs below the holes on the CTP plate 28.

[0084] The scrapping method includes the following steps:

[0085] S1: Feed the CTP plate 28 into the scrapping machine from the feed port 2 and insert it between the needle roller 4 and the optical shaft 6. Start the scrapping machine to make the needle roller 4 and the optical shaft 6 rotate, so that the CTP plate 28 continues to slide towards the discharge port 3, and the needle roller 4 punches holes in the CTP plate 28.

[0086] S2: The burr removal component 22 removes the burrs and flanging caused by the punctures of the needles 5 under the CTP plate 28 by the reciprocating sliding of the deburring plate 23 under the CTP plate 28.

[0087] S3: The hole cleaning assembly 10 removes the debris trapped inside the hole of the CTP plate 28 after it is punctured by the needle 5 by reciprocating the hole cleaning rod 20 above the CTP plate 28.

[0088] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
