Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and specifically discloses a simple CTP plate baking device for monochrome printing of books and periodicals. Background Technology

[0002] In the field of monochrome book and magazine printing, CTP (Computer-to-Plate) technology has become the mainstream plate-making method due to its high efficiency and precision. However, the durability of conventional CTP plates is generally low, typically only 30,000 to 50,000 print runs. Frequent plate replacements not only significantly increase consumable costs but also interrupt continuous printing processes, reducing overall production efficiency.

[0003] To improve the printing durability of CTP plates, the industry commonly uses a baking process to heat-treat the developed printing plates. However, traditional baking equipment has many drawbacks: First, it is complex in structure and bulky, requiring a fixed installation site, making it difficult for small and medium-sized printing companies with limited space to deploy; second, the equipment purchase cost is high, often tens of thousands of yuan, resulting in a high investment threshold; finally, the operation process is cumbersome, usually requiring professional personnel for debugging and maintenance, demanding high skills from operators. Therefore, a simple, portable baking device for CTP plates used in monochrome book and magazine printing is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a simple portable CTP plate baking device for monochrome printing of books and periodicals. It achieves rapid positioning and stable pressing through magnetic pressure cap and limiting mechanism. Combined with precise temperature control and uniform heating, it significantly improves the printing durability of CTP plates. It is easy and safe to operate and greatly reduces the production costs of small and medium-sized printing enterprises.

[0005] This utility model is implemented as follows: a simple portable CTP plate baking device for monochrome printing of books and periodicals includes a heating base and a magnetic pressure cover. The heating base includes a shell and a high-temperature resistant ceramic plate fixedly connected to the upper surface of the shell. A heating tube is arranged inside the shell, and thermally conductive silicone is arranged between the heating tube and the high-temperature resistant ceramic plate. A high-temperature resistant silicone strip is arranged on the lower surface of the magnetic pressure cover. Magnets that can attract each other are arranged at the four corners of the outer walls of the shell and the magnetic pressure cover. Two scales are arranged along the length and width directions on the upper surface of the high-temperature resistant ceramic plate. A support mechanism is arranged between the heating base and the magnetic pressure cover.

[0006] As a preferred embodiment of the portable CTP plate baking device for monochrome printing of books and periodicals according to this utility model, the support mechanism includes two support plates fixedly connected to the left and right end faces of the housing. Two symmetrically distributed limiting rods are fixedly connected to the outer walls of the two support plates. Multiple sliders that are slidably connected to the limiting rods are fixedly connected to the outer wall of the magnetic pressure cover. A sliding groove is opened through the inside of the magnetic pressure cover. Two symmetrically distributed locking rods are slidably connected to the inner wall of the sliding groove. The outer walls of the two support plates are provided with locking holes that match the locking rods. A spring is provided inside the sliding groove between the two locking rods. A lever extending to the outside of the magnetic pressure cover is fixedly connected to the upper end face of the two locking rods.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 A portable CTP plate baking device for monochrome printing of books and periodicals includes a heating base 1 and a magnetic pressure cover 2. The heating base 1 includes a housing 101 and a high-temperature resistant ceramic plate 103 fixedly connected to the upper surface of the housing 101. A heating tube 102 is provided inside the housing 101. Thermally conductive silicone 104 is provided between the heating tube 102 and the high-temperature resistant ceramic plate 103. A high-temperature resistant silicone strip 4 is provided on the lower surface of the magnetic pressure cover 2. Magnets that can attract each other are provided at the four corners of the outer walls of the housing 101 and the magnetic pressure cover 2. Two scales are provided on the upper surface of the high-temperature resistant ceramic plate 103 along its length and width. A support mechanism is provided between the heating base 1 and the magnetic pressure cover 2.

[0022] In this embodiment: The heating base 1 is placed stably on the operating table. The CTP plate, which has been developed and coated with protective adhesive, is precisely positioned on the high-temperature resistant ceramic plate 103 along the limiting block 5 and the scale. Then, the magnetic pressure cover 2 is aligned with the heating base 1 and pressed down, and fixed by the four corner magnets, so that the high-temperature resistant silicone strip 4 presses against the edge of the CTP plate. The target temperature and time are set by the controller, and the heating tube 102 is started for uniform heating. The thermally conductive silicone 104 ensures that the temperature difference on the plate surface is ≤5℃. After the plate baking is completed, the power is automatically cut off. After cooling, the magnetic pressure cover 2 can be removed to take out the CTP plate. This device is designed for monochrome printing. It has a simplified structure and is easy to operate. Plate baking can be completed quickly without professional training. It can quickly position and stably press the CTP plate, greatly improving the operating efficiency. Through uniform heating and precise temperature control, the printing durability of the CTP plate is improved, and the cost of consumables is significantly reduced. The whole device is portable, flexible, and inexpensive, with high economic and practical value.

[0023] As a technical optimization of this utility model, the support mechanism includes two support plates 3 fixedly connected to the left and right ends of the housing 101. Two symmetrically distributed limiting rods 301 are fixedly connected to the outer walls of the two support plates 3. Multiple sliders 205 that are slidably connected to the limiting rods 301 are fixedly connected to the outer wall of the magnetic pressure cover 2. A sliding groove 201 is opened through the inside of the magnetic pressure cover 2. Two symmetrically distributed locking rods 202 are slidably connected to the inner wall of the sliding groove 201. The outer walls of the two support plates 3 are provided with locking holes 302 that match the locking rods 202. A spring 203 located between the two locking rods 202 is provided inside the sliding groove 201. A lever 204 extending to the outside of the magnetic pressure cover 2 is fixedly connected to the upper end face of the two locking rods 202.

[0024] In this embodiment: When pressing down the magnetic cover 2, firstly, the lever 204 moves the two locking levers 202 to slide relative to each other and compress the spring 203, so that the locking levers 202 disengage from the locking holes 302, and the magnetic cover 2 can be pressed down smoothly. After baking, the magnetic cover 2 can be lifted up directly by the handle. Since the upper end of the locking lever 202 is inclined, when lifting the magnetic cover 2, the locking lever 202 can be squeezed into the sliding groove 201, so that the magnetic cover 2 can be lifted smoothly to the top. At this time, the locking lever 202 is aligned with the locking hole 302, and the locking lever 202 is locked into the locking hole 302 under the action of the spring 203, thus fixing the magnetic cover 2.

[0025] As a technical optimization of this utility model, a limit stop 5 is provided on the outer wall of the shell 101.

[0026] In this embodiment: by setting a limiting block 5 on the outer wall of the housing 101, the CTP plate can be positioned quickly and accurately, ensuring that the plate position is consistent each time it is baked, simplifying the operation process and improving production efficiency.

[0027] As a technical optimization of this utility model, the upper side of the opposite ends of the two levers 202 is inclined.

[0028] In this embodiment: by setting the upper side of the opposite end of the two levers 202 as an inclined surface, it is convenient to squeeze the levers 202 inward when the magnetic pressure cover 2 is pulled upward.

[0029] As a technical optimization of this utility model, a limiting groove is provided on the upper end surface of the magnetic pressure cover 2.

[0030] In this embodiment: by opening a limiting groove on the upper end face of the magnetic pressure cover 2, the lever 204 can pass through, and the lever 204 and the limiting groove limit the locking lever 202.

[0031] As a technical optimization of this utility model, anti-slip rubber pads 6 are provided at the four corners of the lower end face of the heating base 1.

[0032] In this embodiment, anti-slip rubber pads 6 are provided at the four corners of the lower end face of the heating base 1 to facilitate the stable placement of the heating base 1.

[0033] As a technical optimization of this utility model, a controller is provided on the outer wall of the heating base 1, and the heating tube 102 is electrically connected to the controller.

[0034] In this embodiment, the controller facilitates precise temperature and time control, improving the stability of the baking plate quality, while also featuring an automatic power-off function for overheating to ensure operational safety.

[0035] The working principle and usage process of this utility model are as follows: Place the heating base 1 stably on the operating table. Position the CTP plate, which has been developed and coated with protective adhesive, precisely on the high-temperature resistant ceramic plate 103 along the limiting block 5 and the scale. Then, use the lever 204 to move the two locking levers 202 relative to each other and compress the spring 203, causing the locking levers 202 to disengage from the locking holes 302. This allows the magnetic pressure cover 2 to be smoothly pressed down. Align the magnetic pressure cover 2 with the heating base 1 and press it down. The four corner magnets will adhere and fix it, pressing the high-temperature resistant silicone strip 4 against the edge of the CTP plate. Set the target temperature using the controller. Temperature and time are controlled, and the heating element 102 is activated for uniform heating. The thermally conductive silicone 104 ensures that the temperature difference on the board surface is ≤5℃. After baking, the power is automatically cut off. After cooling, the magnetic cover 2 is lifted upwards by the handle. Since the upper end of the clamping rod 202 is inclined, it can be squeezed into the slide groove 201 when the magnetic cover 2 is lifted, so that the magnetic cover 2 is smoothly lifted to the top. At this time, the clamping rod 202 is aligned with the clamping hole 302. Under the action of the spring 203, the clamping rod 202 is inserted into the clamping hole 302, fixing the magnetic cover 2. Then the CTP board can be removed.
