Description

Technical Field

[0001] This utility model relates to the field of printing roller cleaning technology, and in particular to a batch continuous cleaning device for printing rollers. Background Technology

[0002] Printing rollers are critical components in industries such as printing, coating, and gravure printing. They are typically cylindrical cylinders with engraved or etched surfaces, or decorated with specific patterns, used to evenly transfer ink or coatings onto substrates such as paper, fabric, and plastic film. After printing, the printing roller needs to be removed from the equipment and replaced with another roller. The removed printing rollers usually require cleaning to remove ink, coatings, and other residues from their surfaces before being stored for later use. To ensure the printing rollers maintain high-quality performance in subsequent printing or coating processes, specialized cleaning equipment is typically used to efficiently remove these residues.

[0003] Existing cleaning devices typically require placing the printing roller in the middle of the cleaning equipment before cleaning its surface using high-pressure nozzles, even though these devices are capable of performing the cleaning operation.

[0004] However, the cleaning process of printing rollers requires a large amount of water, which is discharged as wastewater after one use without being recycled or reused. This leads to a large waste of water resources, especially in water-scarce areas or factories, where water costs and environmental pressures increase, thus increasing cleaning costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a batch continuous cleaning device for printing rollers, which aims to improve the existing technology that requires a large amount of water in the printing roller cleaning process. This water is discharged as wastewater after one use without being recycled or reused, which leads to a large waste of water resources.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A batch continuous cleaning device for printing rollers includes a support frame. A cleaning tank is fixedly connected to the upper part of the support frame. A placement frame is fixedly connected to the rear side of the support frame. A water tank is fixedly connected inside the placement frame. A water pump is fixedly connected to the upper left side of the placement frame. The input end of the water pump is fixedly connected to the inside of the water tank. One end of a delivery pipe is fixedly connected to the output end of the water pump. A guide pipe is provided on the upper part of the cleaning tank. Spray nozzles are installed on both sides of the lower part of the guide pipe. The other end of the delivery pipe is fixedly connected to the inside of the guide pipe. A connecting pipe is fixedly connected to the bottom of the cleaning tank. A filter box is fixedly connected to the bottom of the connecting pipe. The filter box is fixedly connected to the inside of the support frame. A filter plate is inserted inside the filter box. An adsorption plate is inserted at the bottom of the filter box. The adsorption plate is made of polypropylene. A circulation pipe is fixedly connected to the outside of the filter box. The bottom of the circulation pipe is fixedly connected to the inside of the water tank. A replacement component is provided on the front side of the outside of the filter box. The replacement component is used to replace the filter plate and the adsorption plate. A water inlet is fixedly connected to the outside of the water tank.

[0008] Furthermore, the replacement component includes a mounting block, which is fixedly connected to the front exterior of the filter box. A rotating rod is rotatably connected inside the mounting block, a turntable is fixedly connected to the top of the rotating rod, and a second gear is fixedly connected to the bottom of the rotating rod. Rack plates are provided on both sides inside the mounting block, and the two rack plates mesh with the second gear. Guide blocks are fixedly connected to the exterior of the two rack plates, and insertion rods are fixedly connected to the bottom of the two rack plates.

[0009] Furthermore, a motor is provided on the outer right side of the cleaning tank, and a transmission rod is fixed to the output end of the motor. The transmission rods are evenly distributed inside the cleaning tank, and a first gear is fixedly connected to the outer left side of each of the multiple transmission rods. The multiple first gears mesh with each other, and a cleaning roller is fixedly connected to the outer side of each of the multiple transmission rods.

[0010] Furthermore, a guide plate is fixedly connected to the bottom of the inside of the cleaning tank, and an installation ring is fixedly connected to the right side of the outside of the cleaning tank. The motor is fixedly connected inside the installation ring.

[0011] Furthermore, a mounting shell is fixedly connected to the outer left side of the cleaning tank, and multiple first gears are installed inside the mounting shell.

[0012] Furthermore, a conveying plate is fixedly connected to the bottom of the filter box, and a limit rod is inserted inside the filter plate.

[0013] Furthermore, both the filter plate and the adsorption plate have insertion holes inside, and the two insertion rods are respectively inserted into the two insertion holes. Guide rods are fixedly connected to both sides inside the mounting block, and the two guide blocks are slidably connected to the outside of the two guide rods.

[0014] Furthermore, an installation rod is fixedly connected to the outside of the guide tube, and the bottoms of the two installation rods are fixedly connected to the outside of the cleaning tank on both sides.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this invention, during the cleaning of the printing rollers, the printing rollers are first placed on top of the cleaning rollers. A water pump is started to draw cleaning water from the water tank, which is then delivered to the nozzles via a conveying pipe and a guide pipe to clean the printing rollers. Simultaneously, a motor drives a transmission rod and multiple first gears to rotate the cleaning rollers, cleaning them as they rotate. Used water is guided to a filter box via a guide plate, where impurities are first filtered out by the filter plate, then grease is removed by a polypropylene adsorption plate, and finally returned to the water tank via a circulation pipe. This achieves water recycling, reduces the consumption of fresh water, minimizes water waste, and saves cleaning costs.

[0017] 2. In this invention, when the filter plates and adsorption plates need cleaning, rotating the turntable drives the rotating rod and the second gear at the bottom to rotate, causing the rack plate to move and push the insertion rod out of the insertion hole. Then, the filter plates and adsorption plates can be removed from the filter box for cleaning. During installation, the filter plates and adsorption plates are placed back into the filter box, and the turntable is rotated in the opposite direction to allow the insertion rod to re-insert into the insertion hole. This design facilitates the disassembly and cleaning of the filter plates and adsorption plates, prevents clogging, ensures optimal performance, and extends the equipment's lifespan.

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.

[0028] Reference Figures 1-5This utility model provides an embodiment of a batch continuous cleaning device for printing rollers, comprising a support 1, a cleaning tank 2 fixedly connected to the upper part of the support 1, a placement rack 3 fixedly connected to the rear side of the support 1, a water tank 16 fixedly connected inside the placement rack 3, a water pump 18 fixedly connected to the upper left side of the placement rack 3, the input end of the water pump 18 fixedly connected to the inside of the water tank 16, and the output end of the water pump 18 fixedly connected to one end of a conveying pipe 19. A guide pipe 20 is provided on the upper part of the cleaning tank 2, and nozzles 21 are installed on both sides of the lower part of the guide pipe 20. The other end of the conveying pipe 19 is fixedly connected to the inside of the guide pipe 20. A connecting pipe 11 is fixedly connected to the bottom of the cleaning tank 2, and a filter box 12 is fixedly connected to the bottom of the connecting pipe 11. The filter box 12 is fixedly connected to the inside of the support 1, and a filter plate 13 is inserted inside the filter box 12. An adsorption plate 14, made of polypropylene, is inserted at the bottom of the filter box 12. A circulation pipe 15 is fixedly connected to the outside of the filter box 12, and the bottom of the circulation pipe 15 is fixedly connected to... Inside the water tank 16, a replacement assembly 22 is provided on the front side of the filter box 12. The replacement assembly 22 is used to replace the filter plate 13 and the adsorption plate 14. A water inlet 17 is fixedly connected to the outside of the water tank 16. A motor 5 is provided on the right side of the outside of the cleaning box 2. A transmission rod 7 is fixedly fixed at the output end of the motor 5. The transmission rods 7 are evenly distributed inside the cleaning box 2. A first gear 8 is fixedly connected to the left side of the outside of multiple transmission rods 7. The multiple first gears 8 mesh with each other. A cleaning roller 6 is fixedly connected to the outside of multiple transmission rods 7. A guide plate 10 is fixedly connected to the bottom inside the cleaning box 2. An installation ring 4 is fixedly connected to the right side of the outside of the cleaning box 2. The motor 5 is fixedly connected inside the installation ring 4. An installation shell 9 is fixedly connected to the left side of the outside of the cleaning box 2. The multiple first gears 8 are installed inside the installation shell 9. A conveying plate 26 is fixedly connected to the bottom inside the filter box 12. A limit rod 27 is inserted into the inside of the filter plate 13. An installation rod 25 is fixedly connected to the outside of the guide tube 20. The bottom of the two installation rods 25 is fixedly connected to the two sides of the outside of the cleaning box 2.

[0029] Specifically, during the cleaning process of the printing rollers, firstly, the printing rollers are placed on top of the cleaning rollers 6. The water pump 18 is then started, drawing cleaning water from the water tank 16 and delivering it through the delivery pipe 19 to the guide pipe 20. The cleaning water is then delivered through the guide pipe 20 to the nozzle 21, which sprays water evenly onto the surface of the printing rollers above the cleaning rollers 6, thus efficiently cleaning the rollers. Simultaneously, the motor 5 is started, driving the transmission rod 7, which is fixedly connected to its output end, to rotate. The rotation of the transmission rod 7 causes the first gear 8 fixed on its outer left side to rotate as well. The rotation of the first gear 8 drives multiple other first gears 8 meshing with it to rotate, which in turn drives multiple internally connected transmission rods 7 to rotate. The rotation of these transmission rods 7 then drives multiple externally fixed cleaning rollers 6 to rotate synchronously. As the cleaning rollers 6 rotate, the printing rollers placed on top are also driven to rotate, completing the comprehensive cleaning of the printing rollers. During the cleaning process, the used cleaning water is effectively guided by the guide plate 10. Next, the water flows into the filter box 12 through the connecting pipe 11. Inside the filter box 12, the water first passes through the filter plate 13 to initially filter large particles of impurities, removing pollutants such as mud, sand, and paper scraps. Then, the water flows through the polypropylene adsorption plate 14. During this process, the adsorption plate 14 can effectively adsorb grease and other organic pollutants in the water, further purifying the water quality. The clean water after filtration and adsorption is transported back to the water tank 16 through the circulation pipe 15, thereby realizing the recycling of water resources. This design not only allows the cleaning water to be reused, greatly reducing the consumption of fresh water during the cleaning process, but also significantly reduces water waste and the burden on the environment. At the same time, due to the reduced demand for fresh water, the water cost of the enterprise in the cleaning operation is significantly reduced. In addition, filtration and adsorption ensure the cleanliness of the circulating water, avoiding secondary pollution of the printing roller by pollutants during the circulation process, ensuring the stability and efficiency of the cleaning quality. The upper insertion rod 2206 is limited by the setting of the limit rod 27.

[0030] Reference Figures 6-7The replacement component 22 includes a mounting block 2201, which is fixedly connected to the front of the filter box 12. A rotating rod 2203 is rotatably connected inside the mounting block 2201. A turntable 2202 is fixedly connected to the top of the rotating rod 2203, and a second gear 2204 is fixedly connected to the bottom of the rotating rod 2203. A rack plate 2205 is provided on both sides inside the mounting block 2201. The two rack plates 2205 mesh with the second gear 2204. Guide blocks 2207 are fixedly connected to the outside of the two rack plates 2205. Insert rods 2206 are fixedly connected to the bottom of the two rack plates 2205. Insert holes 24 are opened inside the filter plate 13 and the adsorption plate 14. The two insert rods 2206 are respectively inserted into the two insert holes 24. Guide rods 23 are fixedly connected to both sides inside the mounting block 2201, and the two guide blocks 2207 are slidably connected to the outside of the two guide rods 23.

[0031] Specifically, when cleaning the filter plate 13 and adsorption plate 14 is required, firstly, the limiting rod 27 is pulled out from the inside of the filter plate 13, and the turntable 2202 is rotated. The rotation of the turntable 2202 will drive the rotating rod 2203 fixed inside it to rotate together. As the rotating rod 2203 rotates, the second gear 2204 connected to its bottom also begins to rotate. The rotation of the second gear 2204 will further drive the rack plate 2205 meshing with its external sides to move linearly. The movement of the rack plate 2205... The two externally fixed inserts 2206 are directly acted upon, causing them to move outward along a predetermined trajectory. As the inserts 2206 move, they gradually withdraw from the two insertion holes 24, completing their separation. Once the inserts 2206 are completely disengaged from the insertion holes 24, the filter plate 13 and adsorption plate 14 are unlocked from their original fixed positions. The operator can then easily remove the filter plate 13 and adsorption plate 14 from the inside of the filter box 12 for necessary cleaning and maintenance. After cleaning, the filter plate 13 and adsorption plate 14 need to be reinstalled inside the filter box 12. At this time, the operator only needs to insert the cleaned filter plate 13 and adsorption plate 14 into the designated position of the filter box 12, and then rotate the turntable 2202 in the opposite direction. As the turntable 2202 rotates in the opposite direction, the rotating rod 2203 also rotates in the opposite direction, driving the second gear 2204 to rotate in the opposite direction. At this time, the rack plate 2205 moves in the opposite direction, pushing the two external insertion rods 2206 to re-insert into the two insertion holes 24. Then, the limiting rod 27 is inserted into the filter plate 13 to ensure that the filter plate 13 and adsorption plate 14 are firmly fixed in the filter box 12. Through this design, the filter plate 13 and adsorption plate 14 can be easily disassembled and cleaned, avoiding the clogging problem caused by the accumulation of impurities during long-term use. The filter plate 13 and adsorption plate 14 can be kept clean, ensuring that they continuously provide the best filtration and adsorption performance. The two guide rods 23 serve to guide the guide block 2207.

[0032] Working principle: During the cleaning of the printing rollers, firstly, the printing rollers are placed on top of the cleaning roller 6. Then, the water pump 18 is started, and cleaning water is drawn from the water tank 16 through the water pump 18. Then, the water is transported through the conveying pipe 19 to the inside of the guide pipe 20. Then, the water is sprayed out through the nozzle 21 to clean the printing rollers placed on top of the cleaning roller 6. At the same time, the motor 5 is started. The motor 5 drives the transmission rod 7 fixed at the output end to rotate. The rotation of the transmission rod 7 drives the first gear 8 fixed on the outer left side to rotate. The rotation of the first gear 8 drives the multiple meshing first gears 8 to rotate. The rotation of the multiple first gears 8 drives the inner... The rotation of the fixed transmission rod 7 drives the rotation of multiple externally fixed cleaning rollers 6, which in turn rotates the upper-mounted printing roller, thus completing the cleaning of the printing roller. The water used for cleaning is guided by the guide plate 10 and then transported to the filter box 12 through the connecting pipe 11. First, impurities in the water are filtered by the filter plate 13. Then, grease in the water is adsorbed by the polypropylene adsorption plate 14. Finally, the filtered water is transported to the water tank 16 through the circulation pipe 15. This facilitates the filtration of the water used for cleaning the printing roller. Filtration and adsorption allow for water recycling, significantly reducing the consumption of fresh water during cleaning, minimizing water waste, and saving cleaning costs. When cleaning the filter plate 13 and adsorption plate 14 is required, firstly, the limiting rod 27 is pulled out from inside the filter plate 13, then the turntable 2202 is rotated. The rotation of the turntable 2202 causes the internally fixed rotating rod 2203 to rotate, which in turn causes the bottom fixed second gear 2204 to rotate. The rotation of the second gear 2204 causes the externally meshing rack plates 2205 to move, and the movement of the two rack plates 2205 causes the two externally fixed insert rods 2206 to move, thus moving the two... Once the insert rod 2206 is disengaged from the two insertion holes 24, the filter plate 13 and adsorption plate 14 can be removed from the filter box 12 for cleaning. During installation, the filter plate 13 and adsorption plate 14 are inserted into the filter box 12, and then the turntable 2202 is rotated in the opposite direction to insert the two insert rods 2206 into the two insertion holes 24. Then, the limiting rod 27 is inserted into the filter plate 13. This facilitates the disassembly and cleaning of the filter plate 13 and adsorption plate 14, prevents impurities from clogging the filter plate 13 and adsorption plate 14, ensures that the filter plate 13 and adsorption plate 14 always maintain optimal filtration and adsorption performance, and extends the service life of the equipment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
