Description

Technical Field

[0001] This utility model relates to the field of flexographic printing machine technology, specifically to an automatic lubricating oil replenishment device for flexographic printing machines. Background Technology

[0002] During operation, numerous moving parts of a flexographic printing machine, such as the printing plate cylinder, rubber cylinder, transmission gears, and chains, require continuous lubrication to ensure their normal operation, reduce wear, and extend their service life. Traditional flexographic printing machine lubrication methods mostly involve manually adding lubricating oil periodically. Manual addition makes it difficult to accurately control the amount of lubricating oil added, which can easily lead to over-addition, waste, and contamination. Furthermore, it is difficult to replenish the oil in a timely manner. When the flexographic printing machine runs continuously for a long time, it may malfunction and stop due to insufficient lubricating oil, reducing production efficiency and increasing maintenance costs.

[0003] In the prior art, an automatic lubricating oil replenishment device typically consists of a lubricating oil storage tank, an oil pump, an oil pipeline, a distribution valve, and a control system. The control system starts the oil pump to deliver lubricating oil from the storage tank through the oil pipeline to the distribution valve. According to the preset lubrication program and the needs of each lubrication point, the control system controls the electromagnetic switch of the distribution valve and the flow regulating valve of each oil outlet to accurately distribute the appropriate amount of lubricating oil to each lubrication point of the flexographic printing machine.

[0004] However, during the operation of a flexographic printing machine, impurities such as dust, metal particles, and rubber debris may mix into the lubricating oil. These impurities will gradually settle and accumulate on the walls of the oil tank, forming sludge. This can easily cause blockages in the circulation components inside the oil tank. Furthermore, once impurities enter the moving parts of the flexographic printing machine, they will accelerate the wear and damage of the components. Utility Model Content

The drain pipe 4 and collection bottle 5 at one end of the oil storage tank 1 collect the scraped sludge, improving the working and maintenance efficiency of the equipment.

[0023] Example 2

[0024] Please see Figures 1 to 3Based on Embodiment 1, in order to achieve cleaning of the inner wall of the oil storage tank 1, a distribution valve 6 is provided on the surface of the base 2. The distribution valve 6 accurately distributes lubricating oil according to the needs of different lubrication points of the flexographic printing machine. Multiple oil pumps are fixedly connected to one end of the base 2, and oil pipes 3 are fixedly connected to one end of each oil pump. The drain pipe 4 is connected to the oil storage tank 1. A control valve 21 is fixedly connected to the surface of the drain pipe 4. A threaded groove is provided at one end of the drain pipe 4. The threaded groove matches and connects with the threaded part provided on the surface of the collection bottle 5. Multiple arc grooves 20 are formed on the surface of the collection bottle 5. The design of 0 increases the friction of the collection bottle 5, making it easier for operators to grip the collection bottle 5 when installing and removing it. The surface of the oil tank cover 8 has an oil inlet 7, and the surface of the oil inlet 7 is fitted with a sealing cap. A rotating groove is opened at the center of the surface of the oil tank cover 8.

The rotating rod 9 is rotatably connected to the surface of the rotating groove. The rotating rod 9 has a cross-section of a "+" shaped circular plate structure. The top of the rotating rod 9 is higher than the top surface of the oil tank cover 8. One end of the rotating rod 9 is fixedly connected to a handle 10.

[0025] Example 3

[0026] Please see Figures 1 to 4 Based on Embodiment 2, in order to collect and clean the scraped sludge, two rubber grooves 19 are formed on both sides of the surface of the rotating rod 9 away from the handle 10. A limiting plate 15 is inserted into the surface of the rubber grooves 19. The limiting plate 15 allows the shaft 11 and scraper 17 to be placed separately when not in use. The limiting plate 15 has a "T"-shaped plate structure, and a groove is formed on its surface. A rubber strip 16 is fixedly connected to the surface of the groove. Both ends of the rubber strip 16 are fixedly connected to the two sides of the rubber groove 19. A groove is provided at the top of the shaft 11, and one end of the rotating rod 9 is inserted into the groove. Limiting grooves 18 are formed on both sides of the surface of the shaft 11. The limiting grooves 18 are square grooves. One end of the limiting plate 15 is embedded in the limiting groove 18, and one end of the limiting plate 15 is provided with an inclined surface. When the inclined surface is squeezed, it causes the limiting plate 15 to move. A circular groove is formed on the surface of the connecting rod 12 at the ends that are far apart from each other. A rubber block 14 is fixedly connected to the bottom surface of the circular groove. An insert plate 13 is fixedly connected to the other end of the rubber block 14.

The rubber block 14 and the insert plate 13 are provided so that one end of the scraper 17 can always be attached to the inner wall of the oil tank 1.

[0027] In actual use, first unscrew the fuel tank cap 8 from the surface of the fuel tank 1. Then, insert the rotating rod 9 into the groove on the surface of the shaft 11. The shaft 11 presses against the inclined surface of the limiting plate 15, and the rubber strip 16 at the center of the limiting plate 15 changes from its original state to a stretched state. When the limiting plate 15 is fully embedded in the limiting groove 18, the rubber strip 16 returns to its original state. Then, place the shaft 11 into the inner cavity of the fuel tank 1. The inner wall of the fuel tank 1 presses against the scraper 17, causing the rubber block 14 to change from its original state to a compressed state, thus causing the scraper... Scraper 17 is attached to the inner wall of oil tank 1. The oil tank cap 8 and oil tank 1 are screwed back on. The control valve 21 is opened. The handle 10 is turned by hand. The handle 10 drives the shaft 11 to rotate. Scraper 17 is attached to the oil tank 1 to scrape off the oil sludge inside. The sludge is collected in the collection bottle 5 through the drain pipe 4. After collection is completed, the control valve 21 is closed. The collection bottle 5 is screwed out from the drain pipe 4 for pouring and cleaning. After scraper 17 is used, the limit plate 15 can be moved to both sides to remove the shaft 11.
