Technical Field
[0001] The utility model belongs to the technical field of roll rust prevention, and particularly relates to a water scraping and oil coating device that can be used for a roll grinder. Background Art
[0002] At present, when a roll grinder is performing grinding processing, it is necessary to spray coolant on the surface of the roll through a dedicated system, and during the processing, the coolant always adheres to the surface of the roll, playing an anti-rust role while cooling. After the roll processing is completed, it is necessary to use non-metallic soft materials such as polyurethane plates or rubber plates to scrape off the coolant adhering to the surface. During the water scraping process, there cannot be any pauses, and both hands need to apply force evenly. Otherwise, there will be dot-like or strip-like residues of the coolant, which will dry up within a short period of time, thus forming dot-like or strip-like water marks on the surface of the roll. Even after applying anti-rust oil, they cannot be eliminated, which will directly affect the surface quality of the rolled sheet products after the rolling mill is used. Summary of the Invention
[0003] In order to solve the problems that it is difficult to scrape off the coolant adhering to the surface of the roll by manually using non-metallic soft materials such as polyurethane plates or rubber plates after the current roll grinding processing, it is easy to have uneven force applied by both hands, resulting in dot-like or strip-like water marks on the surface of the roll, which are difficult to eliminate and affect the quality of the subsequent rolled sheet products, the utility model provides a water scraping and oil coating device that can be used for a roll grinder. The utility model utilizes the characteristics that the roll itself can rotate and move axially on the grinder, and a plurality of nozzles are circumferentially arranged around the roll.

[0012] 1. By arranging the first pipeline and the second pipeline after being closed around the roll, a plurality of nozzles are evenly arranged around the roll. Then, the roll is driven to rotate and move axially along it. At the same time, the valve of the first main pipe is opened, and the compressed air is ejected from the nozzles to purge and remove the coolant on the surface of the roll. Compared with manual scraping of the coolant, the efficiency is higher, the purging is uniform, and at the same time, the problem of residual water marks on the surface of the roll caused by unstable force during manual scraping of the coolant is effectively avoided, ensuring the scraping effect of the coolant on the surface of the roll.
[0013] 2. By arranging the first pipeline and the second pipeline after being closed around the roll, a plurality of nozzles are evenly arranged around the roll.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments:
[0023] As Figures 1 to 5As shown in the figure, this embodiment provides a water scraping and oil coating device that can be used in a roll grinder. It is arranged on the grinding head of the grinder and is used for water scraping and oil coating of the roll 1. The grinding head is slidably arranged on the grinder. It includes a support 2, a support member 3, a connecting member 4, a first pipeline 5, a second pipeline 6, and a nozzle 7. A support 2 is arranged on one side of the roll 1, and the lower end of the support 2 is connected to the grinding head. The support member 3 is fixedly arranged on the upper end of the support 2. The support member 3 includes a horizontal plate and a vertical plate that are hollow and connected inside. The lower side of the horizontal plate is fixedly connected to the support 2. The connecting member 4 is hinged on the support member 3. The connecting member 4 is hinged above the horizontal plate. The vertical plate is fixedly connected above one end of the horizontal plate close to the roll 1 and is integrally formed with the horizontal plate. A first pipeline 5 is communicated and arranged on one side of the support member 3 close to the roll 1. The inside of the connecting member 3 is hollow and a second pipeline 6 is communicated and arranged on one side close to the roll 1. One side of the vertical plate close to the roll 1 is communicated with the second pipeline 6, as Figure 2 shown, both the first pipeline 5 and the second pipeline 6 are arc-shaped pipelines and are arranged circumferentially around the roll 1. A plurality of nozzles 7 are evenly distributed on the arc-shaped inner sides of the first pipeline 5 and the second pipeline 6. (The nozzle 7 can adopt Yunqige 304 stainless steel duckbill nozzle, universal flat nozzle for air blowing and cleaning, air knife cooling nozzle, duckbill type blowing nozzle, 6-point duckbill nozzle + 6-point universal base. The nozzle slit length is 38 mm and the slit width is 2 mm).
[0024] As Figure 4 shown, the connecting member 4 includes a middle block, a limiting block, and a hinge block. The hinge block is hinged above the horizontal plate and on the side of the vertical plate away from the roll 1. The middle block is fixedly arranged above the hinge block. One end of the middle block close to the roll 1 is fixedly connected to the limiting block. The limiting block is located above the vertical plate. The inside of the middle block and the limiting block is hollow and connected. The first pipeline 5 is fixedly and communicatively arranged with the limiting block. When the connecting member 4 rotates until the limiting block is located above the vertical plate and contacts the vertical plate, the first pipeline 5 and the second pipeline 6 are in a closed state; as Figure 5 shown, when the connecting member 4 rotates until one side of the middle block contacts the upper side of the horizontal plate, the first pipeline 5 and the second pipeline 6 are in an open state.
[0025] The first branch pipes 8 and the second branch pipes 9 are both connected and arranged on the support member 3 and the connecting member 4. The two first branch pipes 8 are both connected to the first main pipe 10. The first main pipe 10 is connected to an air source to provide compressed air through the air source, and the compressed air is conveyed to the two first branch pipes 8 through the first main pipe 8. Subsequently, the compressed gas is respectively conveyed to the first pipeline 5 and the second pipeline 6 through the connecting member 4 and the support member 3, and then sprayed out through a plurality of nozzles surrounding the roller 1 to purge and remove the coolant on the surface of the roller 1. The first main pipe 10 is connected to a dehumidification tank 15. The dehumidification tank 15 is connected to the air source, and the compressed gas provided by the air source is conveyed to the dehumidification tank 15. After the water in the dehumidification tank 15 is separated, the dried compressed air is conveyed to the first main pipe 8 and used to purge the roller 1. The two second branch pipes 9 are both connected to the second main pipe 11. The second main pipe 11 is connected to an oil supply device. The oil supply device includes an oil storage tank 16 connected to the second main pipe 11. An oil pump 17 is arranged on the second main pipe 11. After purging and removing the coolant on the surface of the roller 1, the oil pump 17 conveys the rust preventive oil in the oil storage tank 16 to the two second branch pipes 9 through the second main pipe 11, and then conveys it to the first pipeline 5 and the second pipeline 6 through the connecting member 4 and the support member 3, and then sprays it out through the nozzle 7 to perform the rust preventive oil coating work on the roller 1. During this process, the compressed air and the rust preventive oil are conveyed simultaneously, and the two do not mix in the pipeline, ensuring the uniformity of the oil coating. Valves 12 are arranged on both the first main pipe 10 and the second main pipe 11 to adjust the supply switches of the compressed air and the rust preventive oil through the valves 12.
[0026] Sliding rails 13 are arranged on the grinding machine. Two support seats 14 are slidably arranged on the sliding rails 13. A roller 1 is rotatably arranged between the support seats 14. The diameters of both ends of the roller 1 between the two support seats 14 near the positions of the support seats 14 are smaller than the diameter of the middle part of the roller 1. The roller 1 is rotatably installed on the bearing seats 14 through bearings. A first power mechanism (not shown in the figure) is arranged on the grinding machine to drive the roller 1 to rotate. A second power mechanism (not shown in the figure) is also arranged on the grinding machine to drive the support seats 14 to move along the axial direction of the roller 1.
[0027] During use, when the roller 1 is processed, first move the support 2 of the present invention to the position where the diameters of both ends of the roller 1 are smaller (this position is between the two bearing seats 14), and rotate the connecting member 4 to make the first pipeline 5 and the second pipeline 6 in an open state (as Figure 5 shown), and then move the driving support 2 to the position where the second pipeline 6 is located below the roller 1, and rotate the connecting member 4 to make the first pipeline 5 and the second pipeline 6 in a closed state (as Figure 4As shown in the figure, the roller 1 is then driven to rotate by the first power mechanism, and the roller 1 and the bearing block 14 are driven by the second power mechanism to move axially along the roller 1 on the slide rail 13. At the same time, the valve 12 on the first main pipe 10 is opened, and the compressed air provided by the air source passes through the dehumidifying tank 15, the first main pipe 10, the first branch pipe 8, the connecting piece 4 and the supporting piece 3 in sequence and reaches the first pipeline 5 and the second pipeline 6, and then is ejected through the nozzle 7 to uniformly blow the surface of the roller 1 during rotation and movement, removing the coolant on its surface;
[0028] After the coolant on the surface of the roller 1 is blown and removed, the second power mechanism drives the support seat 14 and the roller 1 to move in the reverse direction, and the valve 12 on the second main pipe 11 is opened. Under the action of the oil pump 17, the rust preventive oil in the oil storage tank 16 is conveyed to the first pipeline 5 and the second pipeline 6 through the second main pipe 11, two second branch pipes 9, the connecting piece 4 and the supporting piece 3 in sequence, and then is ejected through the nozzle 7 simultaneously with the compressed air to perform the rust preventive oil coating work on the surface of the roller 1.
[0029] It should be noted that the compressed air conveying pipeline and the rust preventive oil conveying pipeline of the present invention are two separate pipeline systems. Therefore, the compressed air and the rust preventive oil do not contact and will not mix in the pipeline before being ejected from the nozzle 7.
[0030] As an implementable mode, the grinding head can be used to drive the support 2 to move axially along the roller 1, instead of using the second power mechanism to drive the roller 1 to move axially along its axis, so as to realize the relative movement between the roller 1 and the first pipeline 5 and the second pipeline 6 surrounding the roller 1.
[0031] The above embodiments are only the preferred embodiments of the present invention, and do not limit the implementation scope of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
