Description

Technical Field

[0001] This utility model relates to the field of copper strip precision rolling, and more specifically, it relates to an oil scraping device for copper strip precision rolling. Background Technology

[0002] In the production of copper and copper alloy strip, precision rolling is a key process to ensure the thickness accuracy, surface finish, and mechanical properties of the finished strip. During this process, a large amount of rolling oil is needed to lubricate, cool, and clean the rolls and strip to reduce friction, control roll temperature, and remove metal debris. After the rolling process is complete, the residual rolling oil adhering to the surface of the copper strip must be efficiently and evenly removed.

[0003] Patent CN213613322U discloses an oil suction device for the surface of a copper strip oil removal roller, including an oil removal roller A and an oil removal roller B, which are located above and below the copper strip, respectively. On one side of the oil removal roller A and the oil removal roller B, corresponding oil suction rollers A and B are respectively provided, and the oil suction rollers A and B are pressed against the surfaces of the oil removal rollers A and B, respectively. On the upper side of the oil suction roller A and the lower side of the oil suction roller B, pressure rollers A and B are respectively provided, and the pressure rollers A and B are pressed against the surfaces of the oil suction rollers A and B, respectively. An oil receiver is arranged below the oil suction roller A.

[0004] The oil suction device in the above solution has a simple structure and is easy to use. It can significantly improve the oil removal efficiency and effectively prevent the rolling oil from leaking out of the gaps and being carried back to the copper strip surface by the oil removal roller. However, after a period of use, copper shavings tend to stick to the surface of the oil removal roller. The oil suction roller cannot remove the copper shavings. If the oil removal roller is not cleaned frequently, it will easily scratch and damage the surface, resulting in damage to the copper strip. Frequent cleaning of the oil removal roller also increases auxiliary time, which is time-consuming and labor-intensive.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an oil scraping device for copper strip finishing. The oil removal component can simultaneously remove copper shavings adhering to the oil removal roller during oil removal, thereby preventing copper shavings from scratching the surface of the copper strip and eliminating the need for frequent cleaning of the oil removal roller.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an oil scraping device for copper strip fine rolling includes a base plate, two fixed plates fixedly connected to the base plate, and two oil removal rollers rotatably connected between the two fixed plates. One end of each oil removal roller is fixedly connected to a gear, and two gears are rotatably connected to the fixed plates. The gears mesh with each other, and the two gears mesh with each other. A motor is fixedly connected to the fixed plate, and the rotating shaft of the motor is fixedly connected to the end of the adjacent oil removal roller near the gear. Oil scraping components for scraping oil are provided on the fixed plates and the oil removal rollers.

[0008] The present invention is further configured such that: the oil scraping assembly includes two scraping rollers rotatably connected between two fixed plates, a first transmission roller fixedly connected to the end of the scraping roller away from the motor, and a second transmission roller fixedly connected to the oil removal roller; the first transmission roller is connected to the adjacent second transmission roller via a transmission belt; the scraping roller is in contact with the adjacent oil removal roller; the surface of the scraping roller is provided with several diamond-shaped grooves; and the fixed plate is provided with a strong component for enhancing the oil removal effect.

[0009] The present invention is further configured such that: the strengthening component includes a receiving frame detachably connected between the two fixed plates and a scraping plate detachably connected between the two fixed plates, the receiving frame abutting against the upper degreasing roller, and the scraping plate abutting against the lower degreasing roller.

[0010] The present invention is further configured such that: two rotating rods are rotatably connected between the two fixed plates, a striking rod is fixedly connected to the rotating rod, and fixed rings are fixedly connected to both sides of the rotating rod and the striking rod. A torsion spring is sleeved on the rotating rod, and the two ends of the torsion spring are fixedly connected to the adjacent fixed plate and the adjacent fixed ring, respectively. When the torsion spring is in the normal state, the striking rod is in contact with the adjacent scraping roller, and the scraping roller is provided with a driving component that drives the rotating rod to rotate.

[0011] The present invention is further configured such that: the driving component includes a plurality of positioning rods fixedly connected to both sides of the scraping roller and a trigger block fixedly connected to the positioning rods.

[0012] The present invention is further configured such that a temporary storage frame is placed on the base plate.

[0013] In summary, this utility model has the following beneficial effects: by contacting the scraping roller and the degreasing roller, copper shavings adhering to the degreasing roller can be removed simultaneously during degreasing, thereby avoiding copper shavings scratching the surface of the copper strip and eliminating the need for frequent cleaning of the degreasing roller. Furthermore, the copper shavings remaining on the scraping roller can be removed by striking the scraping roller with a striking rod, thus eliminating the need for frequent cleaning of the scraping roller and further reducing auxiliary time.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] An oil scraping device for copper strip finishing, such as Figures 1-6 As shown, it includes a base plate 1, two fixed plates 2 fixedly connected to the base plate 1, and two oil removal rollers 3 rotatably connected between the two fixed plates 2. One end of the oil removal roller 3 is fixedly connected to a gear 4, and two gears 5 are rotatably connected to the fixed plate 2. The gear 4 meshes with the adjacent gear 5, and the two gears 5 mesh with each other. A motor 6 is fixedly connected to the fixed plate 2, and the rotating shaft of the motor 6 is fixedly connected to the end of the adjacent oil removal roller 3 near the gear 5. The fixed plate 2 and the oil removal roller 3 are provided with oil scraping components for scraping oil.

[0023] like Figures 1-6As shown, when it is necessary to degrease the copper strip, the copper strip can be inserted between the two degreasing rollers 3, and then the motor 6 is started. The motor 6 will then drive the degreasing roller 3 fixedly connected to it to rotate. At this time, the gear 4 fixedly connected to this degreasing roller 3 will also rotate synchronously. Then the gear 4 will drive the other gear 4 to rotate through the two gears 5. Then the other degreasing roller 3 will also rotate. At this time, the lower degreasing roller 3 will rotate clockwise and the upper degreasing roller 3 will rotate counterclockwise. In this way, the rolling oil on the surface of the copper strip can be removed from the copper strip. At this time, the rolling oil will adhere to the two degreasing rollers 3. Then the rolling oil on the two degreasing rollers 3 will come into contact with the oil scraping component and be scraped off by the oil scraping component. This can prevent copper chips from scratching the surface of the copper strip and eliminate the need to clean the degreasing rollers 3 frequently.

[0024] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the oil scraping assembly includes two scraping rollers 7 rotatably connected between two fixed plates 2, a transmission roller 8 fixedly connected to the end of the scraping roller 7 away from the motor 6, and a transmission roller 9 fixedly connected to the oil removal roller 3. The transmission roller 8 and the adjacent transmission roller 9 are connected by a transmission belt 10. The scraping roller 7 is in contact with the adjacent oil removal roller 3. The surface of the scraping roller 7 is provided with several diamond-shaped grooves. The fixed plates 2 are provided with a strengthening component for enhancing the oil removal effect. The strengthening component includes a receiving frame 11 detachably connected between the two fixed plates 2 and a scraping plate 12 detachably connected between the two fixed plates 2. The receiving frame 11 abuts against the upper oil removal roller 3, and the scraping plate 12 abuts against the lower oil removal roller 3.

[0025] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, when the degreasing roller 3 rotates, it drives the transmission roller 2 9 to rotate. Then, the transmission roller 2 9 drives the transmission roller 1 8 and the scraping roller 7 to rotate via the transmission belt 10. At this time, if the rolling oil adheres to the two degreasing rollers 3, the scraping roller 7 will scrape off the rolling oil on the degreasing roller 3. At this time, if there is copper shavings on the surface of the degreasing roller 3, the copper shavings will also enter the diamond-shaped grooves on the surface of the scraping roller 7, so that the copper shavings will be removed from the degreasing roller 3. This can prevent the copper shavings from scratching the surface of the copper strip. Then the degreasing roller 3 continues to rotate. The receiving plate can remove the small amount of rolling oil transferred from the scraping roller 7 to the upper degreasing roller 3, and can also receive the rolling oil flowing down from the scraping roller 7. When the lower degreasing roller 3 rotates, the scraping plate 12 can remove the small amount of rolling oil transferred from the scraping roller 7 to the lower degreasing roller 3.

[0026] like Figure 1 , Figure 5 , Figure 6As shown, two rotating rods 13 are rotatably connected between the two fixed plates 2. A striking rod 14 is fixedly connected to the rotating rod 13. Fixed rings 15 are fixedly connected to both sides of the rotating rod 13 and the striking rod 14. A torsion spring 16 is sleeved on the rotating rod 13. The two ends of the torsion spring 16 are fixedly connected to the adjacent fixed plate 2 and the adjacent fixed ring 15, respectively. When the torsion spring 16 is in the normal state, the striking rod 14 is in contact with the adjacent scraping roller 7. The scraping roller 7 is provided with a driving component that drives the rotating rod 13 to rotate. The driving component includes several positioning rods 17 fixedly connected to both sides of the scraping roller 7 and trigger blocks fixedly connected to the positioning rods 17. 18. When the upper degreasing roller 3 rotates counterclockwise, it will synchronously drive the trigger block 18 to rotate. Then the trigger block 18 will contact the adjacent striking rod 14 and push the striking rod 14, so that the striking rod 14 no longer contacts the scraping rod. At this time, the torsion spring 16 will be in a deformed state. Then the trigger block 18 that is in contact with the striking rod 14 will pass over the striking rod 14 and no longer contact the striking rod 14. At this time, the striking rod 14 will re-contact the scraping roller 7 and strike the scraping roller 7 because the torsion spring 16 is reset. In this way, the copper shavings left on the scraping roller 7 can be removed, and the copper shavings will be prevented from adhering to the scraping roller 7. The same applies when the lower degreasing roller 3 rotates.

[0027] like Figure 1 , Figure 4 , Figure 5 As shown, a temporary storage frame 19 is placed on the base plate 1 to receive copper shavings and rolling oil flowing down from the scraping roller 7 on the lower side.

[0028] Working principle: When it is necessary to degrease the copper strip, the copper strip can be inserted between the two degreasing rollers 3, and then the motor 6 is started. The motor 6 will drive the degreasing roller 3 fixedly connected to it to rotate. At this time, the gear 4 fixedly connected to the degreasing roller 3 will also rotate synchronously. Then the gear 4 will drive the other gear 4 to rotate through the two gears 5. Then the other degreasing roller 3 will also rotate. At this time, the lower degreasing roller 3 will rotate clockwise and the upper degreasing roller 3 will rotate counterclockwise. In this way, the rolling oil on the surface of the copper strip can be removed from the copper strip. At this time, the rolling oil will adhere to the two degreasing rollers 3.

[0029] When the degreasing roller 3 rotates, it also drives the transmission roller 2 9 to rotate. Then, the transmission roller 2 9 drives the transmission roller 1 8 and the scraping roller 7 to rotate via the transmission belt 10. If rolling oil adheres to the two degreasing rollers 3, the scraping roller 7 will scrape off the oil. If copper shavings adhere to the surface of the degreasing roller 3, the shavings will enter the diamond-shaped grooves on the surface of the scraping roller 7, causing them to detach from the degreasing roller 3. This prevents the copper shavings from scratching the copper strip surface. When the upper degreasing roller 3 rotates counterclockwise, it synchronously drives the trigger block 18 to rotate. The trigger block 18 then contacts and pushes the adjacent striking rod 14, causing the striking rod 14 to no longer contact the scraping rod. At this time, the torsion spring 16 will be in a deformed state. The trigger block 18, which is in contact with the striking rod 14, will then pass over... When the striking rod 14 is no longer in contact with the scraping roller 7, the striking rod 14 will re-engage with the scraping roller 7 due to the reset of the torsion spring 16, thereby removing the copper shavings remaining on the scraping roller 7 and preventing them from adhering to the scraping roller 7. The same applies when the lower degreasing roller 3 rotates. Subsequently, the degreasing roller 3 continues to rotate, and the receiving plate can remove the small amount of rolling oil transferred from the scraping roller 7 to the upper degreasing roller 3, and can also receive the rolling oil flowing down from the scraping roller 7. When the lower degreasing roller 3 rotates, the scraping plate 12 can remove the small amount of rolling oil transferred from the scraping roller 7 to the lower degreasing roller 3, thereby removing the copper shavings adhering to the degreasing roller 3 and preventing the copper shavings from scratching the surface of the copper strip. It is also possible to reduce auxiliary time by not frequently cleaning the degreasing roller 3 and the scraping roller 7.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
