Technical Field
[0001] This utility model relates to the field of CTP plate-making machine technology, specifically a filtering device for a CTP plate-making machine. Background Technology
[0002] CTP plate-making machines are generally divided into four main categories: internal drum type, external drum type, flat plate type, and curved plate type. Among these four types, the internal drum and external drum types are currently the most commonly used; high-end CTP plate-making machines with better performance typically use the external drum type. A filtration device is often used inside the CTP plate-making machine to repeatedly circulate the working liquid; this device is the CTP plate-making machine's filtration system.
[0003] For example, application number CN201920087696.4 discloses a filtering device for a CTP plate-making machine, including a main body and a buffer mechanism. A baffle plate is installed on the top of the main body, and an installation chamber is provided inside the main body. A liquid storage tank is placed on the left side of the installation chamber, and the filtering mechanism is fixed on the right side of the installation chamber. This filtering device for the CTP plate-making machine is equipped with a storage mechanism. By opening the chamber door and pulling the baffle outward, the card plate is separated from the card slot, thereby opening the storage mechanism. This makes it very convenient for users to retrieve the testing and maintenance tools placed inside the storage chamber for testing and maintenance of the filtering device. The operation is simple. Conversely, by pushing the baffle inward, the card plate is completely locked inside the card slot, thus closing the storage mechanism and facilitating the storage of testing and maintenance tools. This design has a good storage function, making it very convenient for users to store and use testing and maintenance tools, thereby facilitating the normal operation of the CTP plate-making machine.
[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of vibration of internal parts of the filter device during the transportation of CTP plate-making machines, which affects the normal operation of the filter device, leads to insufficient filtration of impurities and easy clogging, and affects the filtration work of the filter device, it also lacks a good mechanism for storing tools, making it inconvenient for users to store tools for testing and maintenance of the filter device, thus hindering the testing and maintenance of the filter device.
[0005] However, during use, the lack of a cleaning mechanism for the filter device makes it easy for a large amount of impurities to clog the surface of the filter device, which greatly affects the filtration efficiency of the filter device and reduces the performance of the plate-making machine. In addition, the filter device usually requires regular manual maintenance, and there is a lack of accurate prompts for users to come for maintenance when there are too many impurities.

The hose of the plate-making machine body is connected to the rear side of the top of the filter box. Detection mechanisms are fixedly connected to both sides of the bottom of the inner wall of the receiving hopper.

[0008] In a preferred embodiment of this invention, the detection mechanism includes a pressure sensor, the bottom of which is fixedly connected to both sides of the bottom of the inner wall of the receiving hopper. A force-receiving plate is slidably connected inside the receiving hopper. A controller is fixedly connected to the front side of the bottom right side of the plate-making machine body. An indicator light is provided at the bottom of the controller. The left side of the indicator light is fixedly connected to the front side of the bottom right side of the plate-making machine body. Both the pressure sensor and the indicator light are electrically connected to the controller via wires.
[0009] As a preferred embodiment of this utility model, the disassembly and assembly mechanism includes a connector, the inner side of which is fixedly connected to the top of both sides of the receiving hopper, a receiving plug is inserted into the top of the connector, the inner side of the receiving plug is fixedly connected to the bottom of both sides of the filter box, and a rubber ring is fitted on the top of the surface of the connector.
[0010] In a preferred embodiment of this invention, the stabilizing component includes a stabilizing slide bar, the top of which is fixedly connected to both sides of the top of the inner wall of the filter box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, by setting up a motor, drives the scraper ring to move up and down, so that the scraper ring cleans the surface of the filter screen bucket. This solves the problem of the lack of a cleaning structure for the filter device, which makes the surface of the filter device easy to be blocked by a large amount of impurities, thus greatly affecting the filtration efficiency of the filter device and reducing the performance of the plate making machine. In addition, the filter device usually requires regular manual maintenance, and there is no problem of accurately prompting the user to come for maintenance when there are too many impurities. This invention achieves the effect of auxiliary cleaning.
[0016] 2. This utility model, by setting up a detection mechanism, uses a water pump to completely extract the filtered liquid when the plate-making machine body is not discharging the liquid to be filtered, so that only impurities remain in the receiving hopper. At this time, the pressure sensor can detect the weight of the force plate and the impurities on the force plate, and the controller can receive the value detected by the pressure sensor. If the weight value exceeds the threshold, the controller will control the indicator light to turn on, thereby prompting the user to clean the receiving hopper.
[0017] 3. This utility model, by setting up a disassembly and assembly mechanism, allows the user to directly pull the receiving bucket downwards when they need to clean the impurities stored inside. This causes the receiving bucket to pull the connector downwards, and the rubber ring will deform, separating the connector from the receiving plug. This allows the receiving bucket to be removed and the impurities inside to be poured out and cleaned. After cleaning, the connector can be inserted into the receiving plug, and the rubber ring will deform and move above the receiving plug, thus limiting the connector and completing the installation of the receiving bucket.

[0023] 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.
[0024] like Figures 1 to 4 As shown, this utility model provides a filtering device for a CTP plate-making machine, including a plate-making machine body 1, a connecting frame 2, a filter box 3, and a filter screen 4. The bottom of the front right side of the plate-making machine body 1 is fixedly connected to the left side of the connecting frame 2. The inner wall of the connecting frame 2 is fixedly connected to the bottom of the surface of the filter box 3. The top of the filter screen 4 is fixedly connected to the top of the inner wall of the filter box 3. A motor 5 is fixedly connected to the right side of the top of the filter box 3. The output end of the motor 5 extends through the interior of the filter box 3 and is fixedly connected to a screw 6. The top of the surface of the screw 6 is threaded with a screw thread. A screw sleeve 7 is fixedly connected to a scraper ring 8 on its left side. The scraper ring 8 is fitted onto the surface of the filter screen hopper 4. A receiving hopper 9 is provided at the bottom of the filter box 3. A water pump 10 is fixedly connected to the front right side of the plate-making machine body 1. The water pump 10 is connected to the top of the filter box 3 via a hose. The hose of the plate-making machine body 1 is connected to the rear top of the filter box 3. Detection mechanisms 11 are fixedly connected to both sides of the bottom of the inner wall of the receiving hopper 9. Disassembly and assembly mechanisms 12 are fixedly connected to the top of both sides of the receiving hopper 9. Stabilizing components 13 are fixedly connected to both sides of the top of the filter box 3.
[0025] refer to Figure 1 and Figure 2The detection mechanism 11 includes a pressure sensor 111. The bottom of the pressure sensor 111 is fixedly connected to both sides of the bottom of the inner wall of the receiving hopper 9. A force-receiving plate 112 is slidably connected inside the receiving hopper 9. A controller 113 is fixedly connected to the front side of the bottom right side of the plate-making machine body 1. An indicator light 114 is provided at the bottom of the controller 113. The left side of the indicator light 114 is fixedly connected to the front side of the bottom right side of the plate-making machine body 1. The pressure sensor 111 and the indicator light 114 are both electrically connected to the controller 113 through wires.
[0026] As a technical optimization of this utility model, by setting up a detection mechanism 11, when the plate-making machine body 1 is not discharging the liquid that needs to be filtered, the water pump 10 is used to completely extract the filtered liquid, so that only impurities exist in the receiving hopper 9. At this time, the pressure sensor 111 can detect the force plate and the weight of the impurities on the force plate, and the controller 113 can receive the value detected by the pressure sensor 111. If the weight value exceeds the threshold, the controller 113 will control the indicator light 114 to turn on, thereby prompting the user to clean the receiving hopper 9.
[0027] refer to Figure 3 The disassembly and assembly mechanism 12 includes a connector 121. The inner side of the connector 121 is fixedly connected to the top of both sides of the receiving hopper 9. A receiving plug 122 is inserted into the top of the connector 121. The inner side of the receiving plug 122 is fixedly connected to the bottom of both sides of the filter box 3. A rubber ring 123 is fitted on the top of the surface of the connector 121.
[0028] As a technical optimization of this utility model, by setting up the disassembly and assembly mechanism 12, when the user needs to clean the impurities stored in the receiving bucket 9, the user can directly pull the receiving bucket 9 downwards, causing the receiving bucket 9 to pull the plug 121 downwards. Then the rubber ring 123 will deform, causing the plug 121 to separate from the receiving plug 122, thereby removing the receiving bucket 9 and emptying the impurities inside the receiving bucket 9. After cleaning, the plug 121 can be inserted into the receiving plug 122, and the rubber ring 123 will deform and move above the receiving plug 122, thereby limiting the plug 121 and completing the installation of the receiving bucket 9.
[0029] refer to Figure 2 The stabilizing component 13 includes a stabilizing slide bar 131. The top of the stabilizing slide bar 131 is fixedly connected to both sides of the top of the inner wall of the filter box 3. A stabilizing sleeve 132 is slidably connected to the surface of the stabilizing slide bar 131. The inner side of the stabilizing sleeve 132 is fixedly connected to both sides of the scraper ring 8.
[0030] As a technical optimization of this utility model, by setting a stabilizing component 13, during the up-and-down movement of the scraper ring 8, the scraper ring 8 will simultaneously drive the stabilizing sleeve 132 to move up and down. By utilizing the sliding cooperation between the stabilizing slide rod 131 and the stabilizing sleeve 132, the front and rear sides of the scraper ring 8 can be limited in the front, rear, left and right directions, ensuring the stability of the scraper ring 8 during the up-and-down movement, while also ensuring the overall rigidity of the scraper ring 8 and improving the service life of the scraper ring 8.
[0031] refer to Figure 3 Both sides of the bottom of the receiving bucket 9 are fixedly connected with a pressing handle 14, which is made of stainless steel.
[0032] As a technical optimization of this utility model, by setting a downward grip 14, when the user needs to press down to open the receiving bucket 9, the user can hold the downward grip 14 and press down to press down the receiving bucket 9, thereby giving the user a point of force to apply force to the receiving bucket 9.
[0033] refer to Figure 3 An anti-slip block 15 is fixedly connected to the outer side of the inner wall of the downward grip 14. There are three anti-slip blocks 15, which are evenly distributed.
[0034] As a technical optimization of this utility model, by setting the anti-slip block 15, when the user holds the pressing handle 14 to press down on the receiving bucket 9, the user's hand can contact the pressing handle 14 through the anti-slip block 15, which increases the friction between the user's hand and the pressing handle 14 and prevents slippage during the pressing process due to low friction.
[0035] refer to Figure 4 The internal fixed connection of the stabilizing sleeve 132 is a sealing ring 16, which is sleeved on the surface of the stabilizing slide rod 131.
[0036] As a technical optimization of this utility model, by setting a sealing ring 16, when the stabilizing sleeve 132 and the stabilizing slide rod 131 are used to slide together, the sealing ring 16 can seal the gap between the stabilizing sleeve 132 and the stabilizing slide rod 131, preventing impurities in the liquid from entering the movable gap between the stabilizing sleeve 132 and the stabilizing slide rod 131 and causing jamming.
[0037] The working principle and usage process of this utility model are as follows: When the plate-making machine body 1 discharges the liquid during the process into the filter box 3, the liquid to be filtered will be on the outer surface of the filter screen 4. Then, the liquid will enter the interior of the filter screen 4 through the filtration of the filter screen 4. Then, the water pump 10 is started to draw the filtered liquid out of the filter screen 4. The water pump 10 can be connected to an external storage device to store the filtered liquid for later use.
[0038] During the filtration process in the filter hopper 4, the motor 5 is started, which drives the screw 6 to continuously rotate in both directions. The screw 6 then drives the screw sleeve 7 to move up and down, which in turn drives the scraper ring 8 to move up and down. The scraper ring 8 continuously scrapes away the impurities filtered from the outer surface of the filter hopper 4. Since the density of the impurities is greater than that of the liquid, these continuously scraped impurities are stored in the receiving hopper 9.
[0039] When the plate-making machine body 1 is not discharging the liquid that needs to be filtered, the water pump 10 is used to completely extract the filtered liquid, so that only impurities remain in the receiving hopper 9. At this time, the pressure sensor 111 can detect the weight of the force plate and the impurities on the force plate, and the controller 113 can receive the value detected by the pressure sensor 111. If the weight value exceeds the threshold, the controller 113 will control the indicator light 114 to turn on, thereby prompting the user to clean the receiving hopper 9.
[0040] When the user needs to clean the impurities stored in the receiving bucket 9, the user can directly pull the receiving bucket 9 downwards, causing the receiving bucket 9 to pull the plug 121 downwards. Then the rubber ring 123 will deform, causing the plug 121 to separate from the receiving plug 122, thereby removing the receiving bucket 9 and emptying the impurities inside. After cleaning, the plug 121 can be inserted into the receiving plug 122, and the rubber ring 123 will deform and move above the receiving plug 122, thereby limiting the plug 121 and completing the installation of the receiving bucket 9.
[0041] During the up-and-down movement of the scraper ring 8, the scraper ring 8 will simultaneously drive the stabilizing sleeve 132 to move up and down. By utilizing the sliding cooperation between the stabilizing slide rod 131 and the stabilizing sleeve 132, the front and rear sides of the scraper ring 8 can be limited in the front, rear, left and right directions, ensuring the stability of the scraper ring 8 during its up-and-down movement, while also ensuring the overall rigidity of the scraper ring 8 and improving its service life.
[0042] In summary, the filter device used in this CTP plate-making machine, by setting up a motor 5, drives the scraper ring 8 to move up and down, so that the scraper ring 8 cleans the surface of the filter screen 4. This solves the problem of the lack of a cleaning structure for the filter device, which makes the surface of the filter device prone to clogging with a large amount of impurities, thus significantly affecting the filtration efficiency of the filter device and reducing the performance of the plate-making machine. In addition, the filter device usually requires regular manual maintenance, and it lacks the ability to accurately prompt the user to come for maintenance when there are too many impurities.
