Description

Technical Field

[0001] This utility model relates to the aluminum processing industry, and in particular to a fully automatic blowing and control device for foam during the aluminum rolling process. Background Technology

[0002] As is widely known, emulsions play a crucial role in the aluminum rolling process of the aluminum processing industry. Their primary function is to effectively reduce the surface temperature of aluminum alloy sheets during rolling, preventing the formation of oxide films caused by high temperatures and ensuring the stability of product quality. In addition, emulsions can significantly reduce the friction between the aluminum sheet and the rolls during rolling, making the sheet processing smoother and the shaping effect better. At the same time, emulsions can also improve the ductility of the sheet, enabling the aluminum sheet to withstand greater deformation during rolling and increasing processing performance.

[0003] During aluminum rolling, emulsion is evenly sprayed onto the surface of the aluminum material through a spraying device, which has the functions of cooling, lubrication, anti-oxidation, and improving ductility. During the aluminum rolling process, the emulsion flows into the recycling container through the aluminum material and then into the emulsion return tank. The recycled emulsion contains floating oil impurities. The existing technology usually involves manually operating an oil skimmer. After the observation angle is appropriate, the air valve is opened to blow the oil to achieve the purpose of skimming. Due to the high frequency of skimming, the skimming efficiency of workers is low and the labor intensity is high. In addition, skimming requires standing on the top of the emulsion tank to observe and operate, which involves high temperature and high risk. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a fully automatic blowing and control device for foam in the aluminum rolling process.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution: An automatic blowing and control device for foam removal during aluminum rolling includes a motor fixed in the middle of the top plate of an emulsion tank, two sets of ball screws and a rotating assembly disposed on both sides of the emulsion tank, the output shaft of the geared motor being fixedly connected to the input shaft of a cross reducer, transmission rods being fixedly connected to the output shafts on both sides of the cross reducer, bevel gears A being fixed to the two outer ends of the transmission rods, bevel gears B being fixed to the upper ends of the two sets of ball screws, bevel gears A and B being meshed at 90°, the lower ends of the screws being rotatably connected by support rods C fixed to the lower sides of the emulsion tank; an oil skimmer is connected between the screw nuts on the two screws. The rotating assembly includes an electric worm gear reducer, support rod A and support rod B. Support rod A and support rod B are fixed at intervals on the upper and middle parts of the inner wall of the emulsion tank, respectively. The middle and lower parts of the worm of the electric worm gear reducer are respectively fitted into the through holes of support rod A and support rod B. A worm wheel is fixed at the shaft end of the skimmer, and the worm wheel is meshed with the teeth on the worm.

[0007] The fully automatic blowing and control device for foam removal during the aluminum rolling process has an elongated hole on the top plate of the emulsion tank corresponding to the skimmer, and a laser rangefinder sensor installed on the top surface of the workshop is positioned vertically corresponding to the elongated hole.

[0008] The fully automatic blowing and control device for foam during the aluminum rolling process has a liquid level sensor fixed on one side of the top plate of the box and inserted into the emulsion tank.

[0012] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: The fully automatic blowing control device for foam removal during aluminum rolling described in this utility model avoids the safety hazards associated with manual observation by installing a laser rangefinder corresponding to the skimmer on the top plate of the housing.

The rotating assembly includes an electric worm gear reducer 9, a support rod A11, and a support rod B15. The support rods A11 and B15 are fixed at intervals on the upper and middle parts of the inner wall of the emulsion tank 12, respectively. The middle and lower parts of the worm 14 of the electric worm gear reducer 9 are respectively fitted into the through holes of the support rods A11 and B15. A worm wheel 13 is fixed at the shaft end of the skimmer 8, and the worm wheel 13 is meshed with the teeth on the worm 14.

[0018] Furthermore, both ends of the oil skimmer 8 are provided with rotary bearings 16 connected to the lead screw nut 18; specifically, when the lead screw 17 rotates, it drives the lead screw nut 18, the rotary bearing 16 and the oil skimmer 8 to rise and fall together. When the oil skimmer 8 rotates, the lead screw nut 18 does not rotate.

[0019] The fully automatic blowing control device for foam during the aluminum rolling process has an elongated hole on the top plate 5 of the emulsion tank 12 corresponding to the oil skimmer 8. A laser range sensor 2 is set on the top surface 1 of the workshop and is positioned vertically corresponding to the elongated hole. The laser range sensor 2 can automatically measure the position of the oil skimmer 8 after it is raised or lowered, avoiding the safety hazards caused by manual observation.

[0020] The fully automatic blowing and control device for foam removal during the aluminum rolling process has a liquid level sensor 3 fixed on one side of the top plate 5 of the box body and inserted into the emulsion tank 12. The liquid level sensor 3 is used to detect the height of the emulsion in the emulsion tank 12.

[0021] The fully automatic blowing and control device for foam removal during the aluminum rolling process has an angle sensor 10 fixed on the electric worm gear reducer 9. The angle sensor 10 is used to detect the rotational position angle of the skimmer 8.

[0022] The fully automatic blowing control device for foam during the aluminum rolling process is provided with multiple pneumatic blowing valves 22 spaced apart along the width of the emulsion tank 12.

[0023] The fully automatic blowing and control device for foam removal during the aluminum rolling process is provided with bearings 23 between the through holes of support rod A11 and support rod B15 and the worm gear 14.

[0024] The fully automatic foam removal control device for the aluminum rolling process described in this utility model includes a motor 6, a laser rangefinder 2, a liquid level sensor 3, an electric worm gear reducer 9, an angle sensor 10, and multiple pneumatic purge valves 22, all of which are connected to an external control cabinet via signal connections. The specific connection structure is existing technology and will not be detailed further.

When the set value is reached, the signal of the laser rangefinder 2 is sent to the control cabinet. The control cabinet controls the reduction motor 6 to stop working and drives the electric worm gear reducer 9 to start. By fixing the worm gear 13 to the shaft end of the oil skimmer 8, the worm gear 13 drives the oil skimmer 8 to rotate. The rotation position of the oil skimmer 8 is detected by the angle sensor 10. When the oil skimmer 8 rotates to the appropriate angle, the angle sensor 10 sends a signal to the control cabinet. The control cabinet sends a purging command to the on-site pneumatic purging valve 22. The pneumatic purging valve 22 opens and the air source is introduced to purge the foam and impurities above the emulsion. When AI The camera analyzes the signal indicating that the foam has been blown away. The AI ​​camera is fixed inside the upper opening of the emulsion tank 12. The pneumatic valve is closed, and the oil skimmer 8 rotates back to the zero position angle through the start of the electric worm gear reducer 9, thus completing the automatic oil skimming.
