Their processing includes roller core sandblasting, bonding treatment, rubber forming, cloth wrapping, wire winding, and surface processing. Rubber rollers are mainly used in papermaking, printing, dyeing, grain processing, metallurgy, and plastics processing.
[0003] Chinese patent application CN202323080935.9 discloses a roller cleaning device for low-VOC, environmentally friendly, alcohol-free printing, comprising: a cleaning tank; a fixing mechanism installed inside the cleaning tank; a mixing mechanism connected to the upper end of the cleaning tank; a spraying mechanism fixed on the cleaning tank; an adjusting mechanism installed on the spraying mechanism; and a cleaning mechanism installed inside the cleaning tank. This roller cleaning device for low-VOC, environmentally friendly, alcohol-free printing features a fixing mechanism that facilitates fixing the rollers to be cleaned, reducing the inconvenience of roller installation and disassembly; a mixing mechanism that facilitates subsequent cleaning, greatly improving the device's practicality; a spraying mechanism that sprays clean water through nozzles for cleaning; and an adjusting mechanism that not only facilitates spray cleaning but also allows for easy removal of the rollers after cleaning, making the entire device convenient to use. The cleaning mechanism significantly improves cleaning efficiency.
[0004] When the above solution is implemented, the rotating shaft drives the brush bristles to clean the rotating rubber roller. Since both are rotating, centrifugal force is generated. The cleaning liquid and impurities on the rubber will splash under the action of centrifugal force, which makes subsequent cleaning troublesome. Moreover, the subsequent discharge of wastewater is also quite troublesome. To address the above problems, a solution is proposed below. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a roller cleaning device for low-VOC environmentally friendly alcohol-free printing, which can avoid sewage splashing and facilitate sewage collection and discharge.

[0029] Example 1:
[0030] Please see Figure 1-5 A cleaning device for a rubber roller 27 used in low-VOC environmentally friendly alcohol-free printing includes a cleaning box 1. An opening 22 is provided on one side of the cleaning box 1. A symmetrically arranged and slidably sealed door 23 is provided at the opening 22. The opening 22 facilitates loading and unloading, while the sealed door 23 ensures a tight seal during cleaning to prevent wastewater splashing. A cleaning brush 2 is rotatably mounted inside the cleaning box 1. A bracket 3 for placing the rubber roller 27 is provided on one side of the cleaning brush 2. A drive assembly 4 for driving the cleaning brush 2 and the rubber roller 27 is provided outside the cleaning box 1. The drive assembly 4 includes a motor 11, a pulley 12, a belt 13, a rotating shaft 14, and a fixing sleeve 15. Two rotating shafts 14 are provided, passing through the cleaning box 1 and rotatably arranged. One of the rotating shafts 14 is fixedly connected to one end of the cleaning brush 2. Another rotating shaft 14 corresponds to the bracket 3. A fixing sleeve 15 is fitted onto one end of the rotating shaft 14 corresponding to the bracket 3. Bolt holes are provided on its inner wall. It is fixed to the end of the rubber roller 27 by bolts. There are two pulleys 12 with different diameters. By using pulleys 12 with different diameters, there can be a speed difference in the angular velocity between the cleaning brush 2 and the rubber roller 27. Through the transmission of the pulleys 12 with different diameters, the cleaning brush 2 and the rubber roller 27 rotate in the same direction and form a speed difference, generating relative friction. Compared with the traditional reverse rotation method, the cleaning efficiency can be improved by 20-30%. The two pulleys 12 are fixedly connected to the other end of the two rotating shafts 14 respectively. The belt 13 is fitted onto the outside of the two pulleys 12. The motor 11 is fixedly connected to the cleaning box 1. The output shaft of the motor 11 is fixedly connected to one of the pulleys 12.
[0031] A spraying assembly 5 is installed on the top of the cleaning tank 1. The output end of the spraying assembly 5 is located inside the cleaning tank 1. The spraying assembly 5 includes a clean water tank 16, a chemical tank 17, a pump body 18, an electric control valve 19, and a nozzle 20. The clean water tank 16 and the chemical tank 17 are respectively installed on the top of the cleaning tank 1. There are two pump bodies 18. The water inlet ends of the two pump bodies 18 are connected to the clean water tank 16 and the chemical tank 17, respectively. The output ends of the two pump bodies 18 are respectively connected to water pipes 21. Both water pipes 21 are connected to the nozzle 20. There are also two electric control valves 19. The two electric control valves 19 are respectively connected to the two water pipes 21. When one pump body 18 is working, the corresponding electric control valve 19 is opened and the other electric control valve 19 is closed, which can effectively prevent liquid backflow and protect the pump body 18. A wastewater tank 10 is installed on the inner bottom surface of the cleaning tank 1. An outlet 26 adapted to the wastewater tank 10 is opened at the bottom of the cleaning tank 1.
[0032] The cleaning box 1 has symmetrically arranged and slidably equipped blocking components 6 inside. The cleaning box 1 has a horizontally arranged slide rail 25 inside. The two blocking components 6 are slidably engaged with the slide rail 25 respectively. The two sealing doors 23 correspond to the two blocking components 6 respectively. The blocking components 6 and the corresponding sealing doors 23 are connected by a connecting rod 24. The cooperation between the slide rail 25 and the slider ensures the stability of the blocking components 6. When the sealing doors 23 are closed, the connecting rod 24 can simultaneously drive the two blocking components 6 to close together, thereby reducing the operation steps and facilitating operation. The blocking component 6 includes a side 7 and a top surface 8. There are two top surfaces 8. The two side surfaces 7 are arranged symmetrically from top to bottom. The side surfaces 7 are arranged vertically. The upper and lower side surfaces 7 are fixedly connected to one side of the two top surfaces 8. The two top surfaces 8 located at the top of the side surfaces 7 have connection ports 9 that are adapted to the output end of the spraying component 5.
[0033] By adding the blocking component 6, wastewater and impurities can be prevented from splashing into the cleaning tank 1 during cleaning, which facilitates subsequent cleaning. At the same time, a wastewater tank 10 is provided at the bottom of the cleaning tank 1, which facilitates the discharge of wastewater from the cleaning tank 1.
[0034] Working principle:
[0035] In use, open the sealing door 23. The sealing door 23 moves the two blocking parts 6 via the connecting rod 24, thus exposing the bracket 3. The rubber roller 27 is then installed on the bracket 3 through the opening 22. The rubber roller 27 and the bracket 3 rotate in coordination, and one end of the rubber roller 27 is inserted into the fixed sleeve 15. The fixed sleeve 15 and one end of the rubber roller 27 are connected by bolts on the fixed sleeve 15. Closing the sealing door 23 simultaneously causes the two blocking parts 6 to merge, enclosing the cleaning brush 2 and the rubber roller 27 inside. The pump body 18, which is connected to the agent tank 17, can spray the agent onto the cleaning brush 2 and the rubber roller 27 through the pipe and nozzle 20, thereby accelerating the removal of impurities. The motor 11 drives the pulley 12 to rotate, and the pulley 12, belt 13, and shaft 14 drive the cleaning brush 2 and the rubber roller 27 to rotate. The transmission method of belt 13 and pulley 12 causes the cleaning brush 2 and the rubber roller 27 to rotate in the same direction, which achieves a better cleaning effect. After cleaning, the blocking part 6 can prevent the wastewater from splashing when the cleaning brush 2 and the rubber roller 27 rotate. The clean water in the clean water tank 16 can rinse the agent and impurities on the surface of the rubber roller 27 and the cleaning brush 2. The wastewater will fall into the wastewater tank 10 under the action of gravity, and the wastewater tank 10 can be easily poured out through the outlet 26.
