Description

Technical Field

[0001] This utility model relates to the field of printing plate making machine technology, specifically a printing plate making machine that prevents circuit misalignment. Background Technology

[0002] Printing plate setters are important pieces of equipment in the printing industry, mainly used to process printing plates so that they can be used in subsequent printing processes. They contain a large number of components such as resistors, capacitors, and operational amplifiers.

[0003] As printing plate setters are used, the aging or unstable performance of these components can cause circuit misalignment in the printing plate setter. Circuit misalignment may cause malfunctions in the mechanical transmission system of the plate setter, resulting in frequent fault alarms and affecting production efficiency. It may also cause the printing plate to shift position during the plate setting process, making it impossible to align accurately, resulting in uneven or missing image development on the printing plate, thus reducing the image quality of the printing plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a printing plate making machine for preventing circuit misalignment, comprising: a plate making machine 1, a developing chamber 2 fixedly connected to the front side of the plate making machine 1, an exposure table 3 fixedly connected to the inner wall of the developing chamber 2, a spray device 8 provided on the top of the developing chamber 2, a clamping and conveying device 4 provided inside the developing chamber 2, a conveying device 6 provided on the outer wall of the clamping and conveying device 4, a clamping device 5 provided inside the developing chamber 2, and a scraper device 7 provided on the outer wall of the developing chamber 2. The clamping and conveying device 4 can clamp and convey printing plates of different thicknesses to prevent printing plate misalignment. The printing plates are then sent to the exposure table 3 via the conveying device 6. Simultaneously, the clamping device 5 clamps and limits the two sides of the printing plate, and the spray device 8 develops the printing plate, making the development of the printing plate more stable and effectively preventing circuit misalignment during the development process, which would lead to a decrease in development quality. After development, the printing plate is carried by the conveying device 6 and scraped off the developing liquid on the surface of the printing plate by the scraper device 7. Finally, it is sent to the exposure table 3 for exposure. This printing plate punching machine uses a dual-output shaft motor 60 to realize the linkage between the clamping device 4 and the conveying device 6, which simplifies the printing plate process and effectively avoids the phenomenon of circuit misalignment in the printing plate punching machine.

[0028] The clamping device 5 includes a second handle 52, with a bidirectional screw 50 fixedly connected to the outer wall of the second handle 52. A clamping plate 51 is threadedly connected to the outer wall of the bidirectional screw 50. The bidirectional screw 50 passes through the developing chamber 2, and the end of the bidirectional screw 50 away from the second handle 52 is rotatably connected to the inner wall of the developing chamber 2. Rotating the second handle 52 causes the bidirectional screw 50 to rotate, which causes the clamping plate 51 to restrict the printing plate in the middle part of the conveying device 6. Then, the spraying device 8 is activated to spray and develop the printing plate, so that the printing plate is in a stable state throughout the developing process, avoiding shaking of the printing plate during the developing process, which would result in uneven development.

[0029] The clamping device 4 includes a first handle 41, a first screw 40 fixedly connected to the outer wall of the first handle 41, a first slider 42 threadedly connected to the outer wall of the first screw 40, a first bevel gear 43 fixedly connected to the bottom end of the first screw 40, a second bevel gear 44 disposed at the top of the first bevel gear 43, a second screw 45 fixedly connected to the outer wall of the second bevel gear 44, a second slider 46 threadedly connected to the outer wall of the second screw 45, a first pulley 47 rotatably connected to the outer wall of the second slider 46, a first synchronous belt 48 rollingly connected to the outer wall of the first pulley 47, and a second pulley rollingly connected to the outer wall of the first synchronous belt 48. 49. A first roller 410 is fixedly connected to the inner wall of the second pulley 49. A second roller 411 is rotatably connected to the inner wall of the developing chamber 2. A first screw 40 passes through the developing chamber 2. The outer wall of the bottom of the first screw 40 is rotatably connected to the inner wall of the developing chamber 2. The end of the second screw 45 away from the second bevel gear 44 is rotatably connected to the inner wall of the developing chamber 2. The first slider 42 and the second slider 46 are both slidably connected to the inner wall of the developing chamber 2. The first bevel gear 43 meshes with the second bevel gear 44. The outer wall of the first pulley 47 is fixedly connected to the outer wall of the second slider 46. The outer wall of the second pulley 49 is rotatably connected to the outer wall of the first slider 42. The first roller 410 is rotatably connected to the outer wall of the first slider 42, and the other end of the outer wall of the first roller 410 is rotatably connected to the inner wall of the developing chamber 2. The first handle 41 can be rotated according to the thickness of the printing plate, causing the first screw 40 to rotate. This causes the first slider 42 to move upwards with the second pulley 49, allowing the distance between the first roller 410 and the second roller 411 to better clamp the printing plate. The rotation of the first screw 40 causes the first bevel gear 43 to rotate, which in turn causes the second bevel gear 44 to rotate, which in turn causes the second screw 45 to rotate, causing the second slider 46 to move upwards with the first pulley 47. Approaching the second bevel gear 44, the dual-output shaft motor 60 is then activated, causing the first pulley 47 to rotate. This causes the first synchronous belt 48 to rotate the second pulley 49, which in turn causes the first roller 410 to rotate. When the printing plate contacts the first roller 410 and the second roller 411, the rotation of the first roller 410 pushes the printing plate through the space between the first roller 410 and the second roller 411. Simultaneously, the second roller 411 rotates, facilitating the transport of the printing plate. At the same time, the printing plate is well clamped between the first roller 410 and the second roller 411, effectively preventing the offset of the printing plate from affecting the subsequent development of the printing plate.

[0030] The conveying device 6 includes a dual-shaft motor 60. A third pulley 61 is fixedly connected to the output end of the dual-shaft motor 60 on the side away from the first pulley 47. A second synchronous belt 62 is tactilely connected to the outer wall of the third pulley 61. A fourth pulley 63 is tactilely connected to the outer wall of the second synchronous belt 62. A third roller 64 is fixedly connected to the outer walls of both the third pulley 61 and the fourth pulley 63. The output end of the dual-shaft motor 60 on the side away from the third pulley 61 is fixedly connected to the first pulley 47. The end of the third roller 64 away from the third pulley 61 is rotatably connected to the inner wall of the developing chamber 2. The rotation of the dual-shaft motor 60 causes the third pulley 61 to rotate, which in turn causes the second synchronous belt 62 to rotate the fourth pulley 63, which in turn causes the third roller 64 to rotate. When the printing plate comes into contact with the third roller 64, the rotation of the third roller 64 pushes the printing plate toward the exposure table 3, facilitating the movement of the printing plate inside the developing chamber 2.

[0031] The scraper device 7 includes a connecting plate 70, a connecting block 71 fixedly connected to the outer wall of the connecting plate 70, a scraper 72 fixedly connected to the outer wall of the connecting block 71, the outer wall of the connecting plate 70 being fixedly connected to the outer wall of the first slider 42, and the outer wall of the scraper 72 being slidably connected to the inner wall of the developing chamber 2. The conveying device 6 will push the printing plate toward the exposure table 3, and the scraper 72 can scrape off the excess developing liquid on the surface of the printing plate.

[0032] Working principle

[0033] In use, after the plate-making machine 1 completes the plate-making process, the printing plate is sent to the developing chamber 2. At this time, the clamping and conveying device 4 can clamp and convey printing plates of different thicknesses to prevent the printing plates from shifting. Then, the printing plate is sent to the exposure table 3 through the conveying device 6. At the same time, the clamping device 5 clamps and limits the two sides of the printing plate. Then, the spraying device 8 develops the printing plate, making the development of the printing plate more stable and effectively preventing the occurrence of circuit misalignment during the development process, which would lead to a decrease in development quality. After development, the printing plate is scraped off the developing liquid on the surface of the printing plate by the scraper device 7 under the action of the conveying device 6, and finally sent to the exposure table 3 for exposure.

[0034] When the plate-making machine 1 delivers the completed printing plate, the first handle 41 is rotated according to the thickness of the printing plate, causing the first screw 40 to rotate. This causes the first slider 42 to move the second pulley 49 upwards, allowing the distance between the first roller 410 and the second roller 411 to better clamp the printing plate. Simultaneously, the rotation of the first screw 40 causes the first bevel gear 43 to rotate, which in turn causes the second bevel gear 44 to rotate, resulting in the rotation of the second screw 45. This causes the second slider 46 to move the first pulley 47 closer to the second bevel gear 44, preventing the first pulley 47 from moving with the second pulley 49. Upon the occurrence of the first synchronous belt 48 breaking, the dual-output shaft motor 60 is restarted, causing the first pulley 47 to rotate, which in turn causes the first synchronous belt 48 to rotate along with the second pulley 49, thus rotating the first roller 410. When the printing plate contacts the first roller 410 and the second roller 411, the rotation of the first roller 410 pushes the printing plate through the space between the first roller 410 and the second roller 411. At the same time, the second roller 411 rotates, facilitating the transport of the printing plate and effectively clamping the printing plate between the first roller 410 and the second roller 411, thus preventing the printing plate from shifting.

[0035] As the printing plate passes through the clamping device 4, the rotation of the dual-shaft motor 60 causes the third pulley 61 to rotate, which in turn causes the two second synchronous belts 62 to drive the fourth pulley 63 to rotate, thus causing the third roller 64 to rotate. When the printing plate comes into contact with the third roller 64, the rotation of the third roller 64 pushes the printing plate toward the exposure table 3. At the same time, the second handle 52 is turned, causing the bidirectional screw 50 to rotate, which causes the clamping plate 51 to restrict the printing plate in the middle part of the conveying device 6. Then, the spray device 8 is activated to spray and develop the printing plate, keeping the printing plate in a stable state throughout the development process and preventing the printing plate from shaking during development, which could lead to uneven development.

[0036] Before the printing plate enters the exposure table 3 via the conveyor 6, the connecting plate 70 and the connecting block 71 move along with the first slider 42, causing the scraper 72 to move as well. Since the scraper 72 is flush with the first roller 410, the bottom of the scraper 72 contacts the top of the printing plate. Under the action of the conveyor 6, excess developer on the surface of the printing plate can be scraped off. Finally, the printing plate enters the exposure table 3 for exposure.
