Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy strip production technology, specifically to an oiling device for aluminum alloy strip production. Background Technology
[0002] Aluminum alloy strip is a thin metal material made of aluminum and its alloys. Due to its lightweight, high strength, corrosion resistance and good processing performance, it is widely used in aerospace, automobile manufacturing, building decoration and electronics. In the production process of aluminum alloy strip, oiling is a common process. Its main purpose is to protect the material surface, improve processing performance and meet the requirements of subsequent use.
[0003] Oiling devices typically use spraying for oiling. However, because these devices lack components to scrape off excess oil from the strip, the excess oil can form uneven oil spots on the aluminum alloy strip surface, making the strip look untidy and unsightly. Therefore, we propose an oiling device for aluminum alloy strip production to solve this problem. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0023] Example
[0024] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of this utility model discloses an oiling device for aluminum alloy strip production, including a housing 1. An oil drain pipe 12 is fixedly connected to the back of the housing 1, and a valve is installed on the oil drain pipe 12. Since excess oil scraped from the strip surface drips into the interior of the housing 1, the oil drain pipe 12 facilitates the subsequent discharge of accumulated scraped oil. A partition 2 is fixed inside the housing 1, and two guide rollers 3 are rotatably connected to the interior of the housing 1 via bearings on both sides of the partition 2. The unit has two fixed atomizing spray plates 4. An oil supply pipe 5 is fixed to the back of the housing 1. One end of the oil supply pipe 5 is connected to one of the atomizing spray plates 4, and the other end is connected to the other atomizing spray plate 4. Inside the housing 1 is a bidirectional scraper assembly 6 for scraping off excess oil sprayed onto the strip surface. Inside the housing 1 are two rotating shafts 7 connected by bearings. Gears 11 are fixed to the surface of each shaft 7, meshing together to drive the two shafts 7 to rotate synchronously in opposite directions under the action of a motor, thus saving production costs. Cleaning brushes 8 are fixed to the surface of each shaft 7. During the use of this aluminum alloy strip oiling device, openings for strip passage are provided on both sides of the housing 1 via partitions 2. After placing the entire device in a suitable position, one end of the strip can be moved through the left side of the housing 1 into the housing 1. Four guide rollers 3 inside the housing 1 support the strip. As the strip moves inside the housing 1, the two counter-rotating cleaning brushes 8... Brush 8 can clean impurities adhering to the surface of the strip. After cleaning, the strip will continue to move to the atomizing spray plate 4. After the oil inlet of the oil pipe 5 is connected and fixed to the oil conveying equipment, the oil can be sprayed out in a mist form onto the surface of the strip through the atomizing spray plate 4. After the oil spraying is completed, the bidirectional scraper assembly 6 is adjusted to a suitable spacing. When the strip continues to move, the bidirectional scraper assembly 6 can scrape off the excess oil on the surface of the strip. Finally, the strip after scraping off the excess oil will be conveyed out through the right side of the box 1.
[0025] like Figure 3 and Figure 4As shown, in some embodiments, the bidirectional scraper assembly 6 includes two rotating rods 601 rotatably connected inside the housing 1 via bearings. Each rotating rod 601 has a gear 602 on its surface. Two movable plates 603 are slidably connected inside the housing 1. Four guide rails 606 are fixed inside the housing 1, and the two movable plates 603 slide between the four guide rails 606, guiding the movable plates 603 to ensure stability during movement. Two racks 604 are fixed to each movable plate 603, and the racks 604 mesh with corresponding gears 602. The top of the housing 1 is fixed... A cylinder 605 is provided, with its top end sliding through the housing 1 and extending into it, and fixedly connected to one of the movable plates 603. Each movable plate 603 is fixed with an oil scraper 607. In use, the top end of the cylinder 605 is activated to drive the upper movable plate 603 to move downward. At this time, with the cooperation of the rotating rod 601, gear 602 and rack 604, when the upper movable plate 603 moves downward, it can simultaneously drive the lower movable plate 603 to move upward. After the upper and lower movable plates 603 move upward, they will respectively drive the oil scraper 607 to move, thus realizing the adjustment of the distance between the two oil scrapers 607.
[0026] like Figure 3 As shown, in some embodiments, a dust suction hood 9 is fixed inside the housing 1 on the outside of the cleaning brush 8. A dust suction pipe 10 is fixed on the back of the housing 1. One end of the dust suction pipe 10 is connected and fixed to one of the dust suction hoods 9, and the other end of the dust suction pipe 10 is connected and fixed to another dust suction hood 9. When in use, the dust suction pipe 10 can be connected and fixed to the inlet pipe of the vacuuming equipment. Therefore, when using the cleaning brush 8 to clean impurities on the surface of the strip, the dust suction hood 9 can be used to collect the cleaned impurities.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
