Description

Technical Field

[0001] This utility model relates to the field of exposure machines, specifically to a cleaning water circulation heating device for exposure machines. Background Technology

[0002] A plate-making machine is a common piece of equipment used in the printing industry to produce printing plates. It uses an ultraviolet (UV) light source to transfer images or text from a film or pattern onto a printing plate, forming a surface that can be used for printing.

[0003] After the printing plate has been exposed, it needs to be placed in the cleaning device of the plate exposure machine for cleaning. Through cleaning, the photosensitive emulsion on the unexposed parts of the printing plate can be removed. By removing these unexposed photosensitive emulsion parts, the pattern can be clearly displayed, improving the cleanliness and smoothness of the printing plate surface, which facilitates subsequent printing operations.

[0004] Current cleaning devices include a cleaning tank containing a brush plate with bristles, and a cover with a movable plate. During cleaning, the printing plate is adhered to the movable plate, and the cover is placed in the cleaning tank, bringing the printing plate and brush plate into contact. The movable plate moves continuously, causing the printing plate to rub repeatedly against the bristles, which remove the photosensitive emulsion from the printing plate. After cleaning, the photosensitive emulsion, due to its stickiness, adheres to the bristles and is difficult to disperse in the water. Therefore, manual kneading and rubbing of the photosensitive emulsion on the bristles in the cleaning tank is required to detach it from the bristles and allow it to mix into the water. Finally, the water in the cleaning tank is drained, and the water and photosensitive emulsion are discharged together.

[0005] The aforementioned cleaning device has the following disadvantages in actual use: the adhesive adhering to the brush bristles needs to be manually cleaned; in winter, the water temperature is low, and although cleaning gloves are required, it is still quite cold, which is not conducive to improving cleaning comfort. In addition, after the photosensitive adhesive and water are drained, clean water needs to be added back to the cleaning tank, which wastes the drained water and is not conducive to water conservation, resulting in high production costs. Utility Model Content

[0006] The present invention aims to provide a water circulation heating device for a plate exposure machine to achieve water circulation and solve the problem of water waste.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning water circulation heating device for a plate exposure machine, comprising a cleaning tank, a brush plate provided inside the cleaning tank, brush bristles on the top of the brush plate, a cover rotatably mounted on the top of the cleaning tank, a movable plate movably mounted on the inner side of the cover, a drive mechanism for driving the movable plate on the cover, and also including a heating box, a water pump, a filter, and a connecting pipe; one end of the connecting pipe is a water inlet end connected to the cleaning tank, and the other end of the connecting pipe is a water outlet end connected to the cleaning tank, the connecting pipe passing through the heating box, the water pump, and the filter.

[0008] The principle and advantages of this solution are as follows: During cleaning, the printing plate is adhered to the movable plate, and the cover is placed on the cleaning tank. The bristles of the printing plate and the brush plate are in contact. Through the continuous movement of the movable plate, the printing plate is repeatedly rubbed against the bristles, and the bristles clean off the photosensitive emulsion on the printing plate. Then, the photosensitive emulsion on the bristles is manually rubbed and cleaned to detach it from the bristles, and the photosensitive emulsion mixes into the water.

[0009] Simultaneously, the water pump is turned on, and water from the cleaning tank enters the connecting pipe through the inlet. Impurities such as photosensitive adhesive follow the water into the connecting pipe. The liquid then enters the filter, where it is filtered. The water then flows out of the filter and back into the cleaning tank. Thus, this solution achieves the filtration of the liquid in the cleaning tank, allowing it to be recycled and reducing water waste. Furthermore, the continuous filtration by the filter ensures the cleanliness of the returned liquid.

[0010] In winter, when the liquid is circulating, the heating box is turned on to heat the returning liquid, thereby raising the temperature of the liquid in the cleaning tank. This prevents the liquid temperature from getting too low when manually cleaning the adhesive residue adhering to the brush bristles, thus improving the comfort of cleaning the brush bristles.

[0011] Preferably, as an improvement, the liquid in the connecting pipe flows back to the cleaning tank after passing through a filter, a water pump, and a heating box in sequence.

[0012] Therefore, the filter first filters the liquid, and then the liquid passes through the water pump and heating chamber, thus preventing liquid containing impurities such as photosensitive emulsion from entering the water pump and heating chamber and causing blockage, which helps to improve the service life of the water pump and heating chamber.

[0013] Preferably, as an improvement, the filter includes a housing and a lifting block. The housing has a placement cavity inside, and both sides of the housing have through holes communicating with the placement cavity. The top of the housing has a placement opening, through which the lifting block is placed into the placement cavity. A filter element is detachably connected to the lifting block, with the filter element and the through holes facing each other.

[0014] Therefore, the filter element is detachably connected to the lifting block. The lifting block is inserted into the placement chamber, with the filter element and the through hole facing each other. Liquid enters the housing through the through hole on one side, flows through the filter element, and the filter element filters the liquid. The filtered liquid then flows out of the housing through the other through hole. After the filter has been used for a period of time, a lot of photosensitive adhesive and other impurities will accumulate on the filter element. At this time, pull the lifting block upwards, and the lifting block will come out of the placement chamber. Remove the filter element from the lifting block and replace it. Then put the lifting block back into the placement chamber. This achieves filter element replacement, preventing the accumulation of photosensitive adhesive and other impurities on the filter element from affecting the filter's filtration performance and ensuring the filter's filtration capacity.

[0015] Preferably, as an improvement, the lifting block is provided with a placement hole, and the filter element is placed in the placement hole.

[0016] Preferably, as an improvement, the filter element is provided with a receiving groove, and the bottom of the receiving groove is provided with multiple filter holes, and the receiving groove is opposite to the through hole near the cleaning tank.

[0017] Therefore, the filter element is placed in the placement chamber, and the receiving tank is opposite to the through hole near the cleaning tank. Liquid passes through the filter element, and impurities such as photosensitive adhesive can enter the receiving tank and be contained therein. This design of the receiving tank improves the filter element's ability to contain impurities such as photosensitive adhesive. During the upward pulling of the lifting block, impurities such as photosensitive adhesive will not fall into the placement chamber.

[0018] Preferably, as an improvement, the outer wall of the lifting block is provided with multiple sealing rings. When the lifting block is inserted into the placement cavity, the sealing rings can improve the sealing between the outer wall of the lifting block and the inner wall of the placement cavity, preventing liquid from flowing out from the gap between the outer wall of the lifting block and the inner wall of the placement cavity.

[0019] Preferably, as an improvement, a valve is provided on the connecting pipe. The valve can open and close the flow of liquid in the connecting pipe.

[0020] Preferably, as an improvement, the cleaning tank is located on top of the exposure machine, and a support plate is fixedly installed on the outer wall of the exposure machine, with the filter mounted on the support plate. Thus, the support plate supports the filter. The filter is close to the cleaning tank; liquid flowing out of the cleaning tank first passes through the filter for filtration, allowing the filter to promptly filter the liquid flowing out of the cleaning tank.

[0021] Preferably, as an improvement, it also includes a support frame for supporting the heating tank and the water pump. The support frame is used to support the water pump and the heating tank.

[0022] Preferably, as an improvement, the drive mechanism includes a rotating rod, a swing rod, and a connecting rod. The rotating rod is rotatably mounted on the cover, the swing rod and the rotating rod are fixedly connected, and the connecting rod is connected between the swing rod and the movable plate.

[0023] Thus, the rotating rod rotates, causing the pendulum to swing. The pendulum rotates around the center of the rotating rod, and the pendulum, through the connecting rod, drives the movable plate to move continuously. Using this method to drive the movement of the movable plate allows for rapid movement of the plate, and the drive mechanism is simple. Attached Figure Description

[0030] The basic implementation examples are as follows: Figures 1-5 As shown: The plate exposure machine uses a water circulation heating device, which includes a cleaning tank 4 located at the top of the plate exposure machine 1. The cleaning tank 4 contains a cleaning trough. A brush plate 5 is installed inside the cleaning tank 4. The brush plate 5 is fixed to the bottom of the cleaning tank 4 by bolts. Brush bristles 6 are fixed on the top of the brush plate 5, and the brush bristles 6 are arranged vertically upwards.

[0031] The top of the cleaning tank 4 is fitted with a cover 2 via a hinge. A handle 27 is located at the end of the cover 2. A movable plate 3 is movably mounted on the inner side of the cover 2. A drive mechanism for moving the movable plate 3 is provided on the cover 2. Figure 2 and Figure 3 As shown, the driving mechanism includes a rotating rod 25, a swing rod 24, and a connecting rod 26. There are two sets of rotating rods 25, swing rods 24, and connecting rods 26, which allows for stable driving of the movable plate 3. The rotating rod 25 is perpendicular to the inner side of the cover 2 and is rotatably mounted on the cover 2. The swing rod 24 is perpendicular to the rotating rod 25, and the ends of the swing rod 24 and the rotating rod 25 are welded or bolted together. The connecting rod 26 is perpendicular to the swing rod 24, and the end of the connecting rod 26 is bolted to the end of the swing rod 24 furthest from the rotating rod 25. The other end of the connecting rod 26 is bolted to the movable plate 3. Two motors (not shown) are mounted on the cover 2, and the output shafts of the two motors are coaxially fixed to the two rotating rods 25 via couplings. Thus, the motors drive the rotating rods 25 to rotate, which in turn drives the swing rods 24 to swing, and the swing rods 24, through the connecting rods 26, move the movable plate 3. In this embodiment, the two sets of swing arms 24 have the same swing orientation and speed. In this embodiment, the length and width of the movable plate 3 are smaller than the length and width of the cleaning tank 4 (the difference between the length of the movable plate 3 and the length of the cleaning tank 4, and the difference between the width of the movable plate 3 and the width of the cleaning tank 4 can be 10-20cm), so that the movable plate 3 has sufficient space to move within the cleaning tank 4.

[0032] The plate exposure machine's cleaning water circulation heating device also includes a heating tank 15, a water pump 9, a filter, and connecting pipes. In this embodiment, the connecting pipes include a discharge pipe 14, a feed pipe 18, an intermediate pipe 11, and a connecting pipe 12. One end of the discharge pipe 14 is the water inlet and is connected to the cleaning tank 4, while the other end of the discharge pipe 14 is connected to the filter. The connecting pipe 12 connects the water pump 9 and the filter. The intermediate pipe 11 connects the water pump 9 and the heating tank 15. One end of the feed pipe 18 is connected to the heating tank 15, and the other end of the feed pipe 18 is the water outlet and is connected to the cleaning tank 4.

[0033] In this embodiment, a valve 10 is provided on the connecting pipe 12. By controlling the valve 10, the entry of liquid into the water pump 9 is controlled. A support plate is fixed (e.g., welded) on the outer wall of the exposure machine 1. The filter is mounted on the support plate, and the support plate supports the filter. A water pump seat 7 is provided at the bottom of the water pump 9 (the water pump 9 and the water pump seat 7 are fixedly connected by bolts). A first support frame 8 is connected to the water pump seat 7, which supports the water pump seat 7, and the water pump seat 7 supports the water pump 9. A heating box seat 16 is provided at the bottom of the heating box 15 (the heating box seat 16 and the heating box 15 are fixedly connected by bolts). A second support frame 17 is connected to the heating box seat 16, which supports the heating box seat 16, and the heating box seat 16 supports the heating box 15.

[0034] Combination Figure 4 and Figure 5 As shown, the filter in this embodiment includes a housing 13 and a lifting block 19. The housing 13 is placed on a support plate and can be fixed to the support plate by bolts. The housing 13 has an internal placement cavity, and its top has a placement opening communicating with the placement cavity. Both sides of the housing 13 have through holes communicating with the placement cavity, with the two through holes facing each other. One through hole is used to connect to the end of the discharge pipe 14, and the other through hole is used to connect to the end of the connecting pipe 12. The lifting block 19 is placed into the placement cavity through the placement opening. A filter element 21 is detachably connected to the lifting block 19. Specifically, the detachable method is as follows: the lifting block 19 has a placement hole, the outer wall of the filter element 21 matches the shape of the placement hole, and the filter element 21 is placed in the placement hole. The filter element 21 and the through hole on the housing 13 are opposite each other. In this embodiment, the filter element 21 is provided with a receiving groove 23, and the bottom of the receiving groove 23 is provided with multiple filter holes 22. The receiving groove 23 is opposite to the through hole (connected to the discharge pipe 14) near the cleaning tank 4. The bottom of the receiving groove 23 is opposite to another through hole (connected to the connecting pipe 12). Multiple sealing rings 20 are installed on the outer side wall of the lifting block 19. Specifically, the outer side wall of the lifting block 19 is provided with multiple sealing ring grooves, and the sealing rings 20 are installed in the sealing ring grooves.

[0035] The specific implementation process is as follows: Open the cover 2, adhere the exposed printing plate to the surface of the movable plate 3 (the surface of the movable plate 3 is adhesive), place the cover 2 on the cleaning tank 4, and press the movable plate 3 over the brush bristles 6. The printing plate on the movable plate 3 is in contact with the brush bristles 6. Then start the motor, which drives the rotating rod 25 to rotate. The rotating rod 25 drives the swing rod 24 to rotate around the rotating rod 25. The swing rod 24 drives the movable plate 3 to move continuously through the connecting rod 26. The movable plate 3 and the brush bristles 6 move relative to each other, and the movable plate 3 drives the printing plate to rub repeatedly on the brush bristles 6, which cleans away the photosensitive emulsion on the printing plate. After cleaning for a period of time, open the cover 2, and the cleaned-off photosensitive emulsion and other impurities adhere to the brush bristles 6.

[0036] Then, the photosensitive adhesive on the brush bristles 6 is manually kneaded and cleaned to detach it from the bristles and allow it to mix into the water. While the bristles 6 are being cleaned, the water pump 9 is turned on. Water from the cleaning tank 4 is pumped by the water pump 9 and flows through the discharge pipe 14 into the filter. The filter filters the liquid, and the water flows out of the filter. The liquid then flows through the connecting pipe 12 back into the water pump 9 and through the intermediate pipe 11 into the heating chamber 15. The heating chamber 15 heats the liquid, and the heated liquid flows back into the cleaning tank 4 through the feed pipe 18. The heating chamber 15 is equipped with heating wires to heat the liquid.

[0037] Therefore, during the manual cleaning of the brush bristles 6, the liquid in the cleaning tank 4 is simultaneously filtered. The liquid in the cleaning tank 4 is filtered and then returned to the cleaning tank 4, thus achieving liquid recycling and reducing water waste. At the same time, the continuous filtration of the liquid by the filter ensures the cleanliness of the returned liquid.

[0038] In winter, when the liquid is circulating, the heating box 15 is turned on to heat the returning liquid, thereby raising the temperature of the liquid in the cleaning tank 4. This ensures that the liquid temperature is not too low when the hands are manually cleaning the adhesive residue adhering to the brush bristles 6, thus improving the comfort of cleaning the brush bristles 6.

[0039] As shown in Figure 4, the filtration principle of the filter is as follows: Liquid enters the housing 13 through the through-hole and flows into the receiving groove 23 of the filter element 21. Impurities such as photosensitive adhesive remain in the receiving groove 23. The liquid flows out through the filter hole 22 at the bottom of the filter element 21 and out through the through-hole on the other side of the housing 13. After the filter has been used for a period of time, the impurities in the receiving groove 23 will increase, requiring cleaning of the impurities in the receiving groove 23 or replacement of the filter element 21. At this time, pull the lifting block 19 upward. The lifting block 19 moves upward and moves out of the housing 13. The lifting block 19 moves the filter element 21 upward together, and the filter element 21 moves to the outside of the housing 13. Then, the filter element 21 is removed from the lifting block 19, the impurities on the filter element 21 are cleaned, and it is reinstalled into the placement hole of the lifting block 19, or a new filter element 21 is installed in the placement hole. After the filter element 21 is installed on the lifting block 19, the lifting block 19 is reinserted into the placement chamber, with the filter element 21 facing the through hole, and the water is filtered the next time it is used.
