Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and specifically to an oiling assembly for single-sided aluminum plates. Background Technology

[0002] Oiling aluminum sheets can achieve the following effects: 1. During the stamping process of aluminum sheets, oiling can lubricate, reduce friction, protect the mold, and extend the service life of the mold; 2. Improve the surface properties of aluminum sheets, such as increasing surface smoothness and improving the effect of subsequent coatings; In actual production, in order to meet the corresponding production needs, sometimes it is necessary to only oil one side of the aluminum sheet.

[0003] Most existing aluminum plate oiling methods first involve conveying the aluminum plate through rollers. During this process, the aluminum plate passes over rollers whose surfaces are continuously coated with oil. The oil-coated rollers then apply the oil from themselves to the aluminum plate surface to complete the oiling process. However, during this continuous oiling process, oil may drip onto the lower rollers during the conveying or feeding of aluminum plates, causing oil contamination on the lower surface of the aluminum plate. This can lead to the processed aluminum plate not meeting production requirements. Therefore, scrapers are often installed on the outer periphery of the lower rollers to clean them and ensure their cleanliness, thereby reducing the contamination of the lower surface of the aluminum plate by the oil on the lower rollers and ensuring the pass rate of the processed aluminum plate. However, when using scrapers to clean the rollers, the cleaning effect of the scrapers will decrease if the scrapers wear down and are not noticed by the workers in time. This will result in oil contamination on the lower surface of the aluminum plate, leading to a decrease in the pass rate of the processed aluminum plate. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the failure to check the scraper of the cleaning lower side roller in time will cause the lower side of the aluminum plate to be contaminated with oil, resulting in unqualified aluminum plate processing. This invention provides a single-sided oiling component for aluminum plates.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention provides the following technical solution: a single-sided oiling aluminum plate oiling assembly, comprising a support frame, on which are arranged an upper side roller, a lower side roller, an oiling roller, and an oiling roller distributed along the aluminum plate conveying direction. A central shaft is provided below the lower side roller, and a cleaning frame located on the outer periphery of the lower side roller is rotatably connected to the central shaft. A scraper is provided on the inner wall of the cleaning frame facing the aluminum plate entry side. A counterweight bar and a water spray plate for spraying cleaning liquid are provided on the side of the cleaning frame away from the aluminum plate entry end. The counterweight bar and water spray plate allow the cleaning frame to be flipped and tilted to make the scraper fit against the lower side roller.

[0006] As a further optimization of the single-sided oiling aluminum plate oiling assembly of this utility model: the distance between the counterweight bar and the central axis is greater than the distance between the scraper and the central axis.

[0007] As a further optimization of the single-sided oiling aluminum plate oiling assembly of this utility model: the cleaning rack is set at an angle.

[0008] As a further optimization of the single-sided oiling aluminum plate oiling assembly of this utility model: a liquid guide frame is provided below the cleaning frame, and the width of the liquid guide frame is greater than the width of the cleaning frame.

[0009] As a further optimization of the single-sided oiling aluminum plate oiling assembly of this utility model: the end of the liquid guide frame that protrudes from the support frame is the outlet, and the inner wall of the liquid guide frame is inclined towards the outlet end and away from the outlet end.

[0010] As a further optimization of the single-sided oiling aluminum plate oiling assembly of this utility model: the scraper is set at an angle.

[0011] As a further optimization of the single-sided oiling assembly for aluminum plates of this utility model: a recycling rack is provided below the oiling roller and the coating roller, and the recycling rack is fixedly mounted on the support frame.

[0012] As a further optimization of the single-sided oiling assembly for aluminum plates of this utility model: the water spray plate is connected to a pressure-adjustable delivery pump through an elastic delivery pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses a central shaft to support the rotation of the cleaning frame. A counterweight and a water spray plate are placed on the side of the cleaning frame away from the aluminum plate entry end to increase the weight on that side, causing the cleaning frame to tilt and rotate away from the aluminum plate entry end. This allows the scraper on the side of the cleaning frame facing the aluminum plate entry end to press against the lower side roller, thus achieving high-quality cleaning of the lower side roller. Furthermore, when the scraper wears down, it can be kept in contact with the surface of the lower side roller without adjustment by personnel, maintaining the cleaning quality of the lower side roller and reducing the probability of the aluminum plate being processed unqualified due to oil contamination on the lower side roller.

[0019] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0020] like Figure 1-3 As shown, a single-sided oiling assembly for aluminum plates, similar to existing technologies, includes a support frame 1. The support frame 1 is equipped with an upper roller 302, a lower roller 301, an oiling roller 303, and an oiling roller 304 arranged along the aluminum plate conveying direction. An oiling pipe 305 is correspondingly provided above the oiling roller 303 and the oiling roller 304. The oiling pipe 305 can continuously deliver oil between the oiling roller 303 and the oiling roller 304, so that the oil on the surface of the oiling pipe 305 can maintain a certain amount. The upper roller 302 and the lower roller 301 rotate relative to each other to convey the aluminum plate. The oiling roller 303 rotates in the aluminum plate conveying direction to apply oil to the surface of the aluminum plate. The oiling roller 304 rotates in the same direction as the oiling roller 303 to squeeze the oil between the oiling roller 304 and the oiling roller 303, so that the oil is evenly coated on the oiling roller 303, so that the oiling roller 303 can evenly apply oil to the surface of the aluminum plate.

[0021] The lower roller 301 is located between the upper oil roller 303 and the upper roller 302, thereby maintaining the positional stability of the aluminum plate as it passes through the upper oil roller 303 while ensuring stable transmission of the aluminum plate, thus guaranteeing the quality of the oil on the surface of the aluminum plate.

[0022] Below the oiling roller 304 and the upper oiling roller 303, there is a recovery rack 306 fixed on the support frame 1. The recovery rack 306 can collect the oil flowing out from both ends of the oiling roller 304 and the upper oiling roller 303, and can also recover the collected oil for reuse. Specifically, the inlet end of the pump connected to the upper oil pipe 305 can be connected to the corresponding oil recovery cylinder, and the oil recovery cylinder corresponds to the outlet of the recovery rack 306, thereby achieving the purpose of reusing the recovered oil.

[0023] Unlike existing technologies, the lower roller 301 is provided with a central shaft 206 fixedly connected to the support frame 1. The central shaft 206 is rotatably connected to a cleaning frame 204. The cleaning frame 204 is provided with a counterweight 205 and a water spray plate 202 on the side away from the aluminum plate entry direction. The water spray plate 202 can spray cleaning water to impact the surface of the lower roller 301 to clean the lower roller 301. The inner wall of the cleaning frame 204 facing the aluminum plate entry direction is provided with a scraper 203. The weight of the counterweight 205 and the water spray plate 202 will drive the cleaning frame 204 to rotate around the central shaft 206 as the fulcrum, so that the scraper 203 stably presses against the surface of the lower roller 301 to clean the surface of the lower roller 301. When the scraper 203 is worn or damaged, the rotation range of the cleaning frame 204 will be increased so that the scraper 203 continues to press against the surface of the lower roller 301 to maintain the cleaning quality.

[0024] The distance between the end of the cleaning rack 204 away from the aluminum plate entry direction and the central axis 206 is greater than the distance between the end of the cleaning rack 204 facing the aluminum plate entry direction and the central axis 206. That is, the torque of the cleaning rack 204 away from the aluminum plate entry direction with the central axis 206 as the center is greater than the torque of the cleaning rack 204 facing the aluminum plate entry direction. This increases the force of the counterweight bar 205 and the water spray plate 202 driving the scraper 203 to press against the lower side roller 301. This maintains the function of the scraper 203 in removing impurities from the surface of the lower side roller 301, thus maintaining the cleaning quality of the lower side roller 301.

[0025] Below the cleaning rack 204 is a liquid guide rack 201 fixedly mounted on the support frame 1. The liquid guide rack 201 can collect the cleaning liquid flowing out from one side of the cleaning rack 204, and can also discharge the cleaning liquid for recycling and reuse. Specifically, the inlet end of the delivery pump supplying water to the spray plate 202 is connected to the cleaning liquid recovery cylinder, and the cleaning liquid recovery cylinder corresponds to the discharge end of the cleaning rack 204, thereby achieving the purpose of reusing the cleaning liquid. The cleaning rack 204 is set at an angle along its length, with one side higher than the other, which facilitates the discharge of the cleaning liquid.

[0026] The scraper 203 is inclined, which reduces the contact area between the scraper 203 and the surface of the lower roller 301 at the same time. This reduces the force that the scraper 203 bears when scraping impurities from the surface of the lower roller 301, thereby reducing the rate of wear or damage to the scraper 203 to a certain extent, and thus improving the service life of the scraper 203 to a certain extent.

[0027] The inner walls of the liquid guide rack 201 and the recovery rack 306 are inclined with the discharge port lower than the discharge port end, so that the cleaning liquid or oil can be discharged quickly, thereby reducing the probability of cleaning liquid or oil overflow, and at the same time maintaining the stability of reusable cleaning liquid or oil.

[0028] The water spray plate 202 is connected to a pressure-variable delivery pump, such as a delivery pump with a valve, through an elastic delivery pipe passing through the support frame 1. The pressure change of the delivery pump can increase the force of the water spray plate 202 impacting the lower side roller 301, thereby increasing the amount of tilt of the cleaning frame 204 away from the aluminum plate. This helps the operator adjust the force of the scraper 203 pressing against the lower side roller 301, so that the operator can adjust it according to the situation to maintain a high-quality cleaning effect on the lower side roller 301. The elastic telescopic pipe can maintain the delivery function of the cleaning liquid when the water spray plate 202 deflects.

[0029] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
