Description

Technical Field

[0001] This utility model relates to a rolling mill cleaning device. Background Technology

[0002] In the aluminum foil rolling process, the blowing position of the fan-shaped blowing nozzle of the blowing device is very important. If the position is not correct, the rolling oil will not be blown clean, resulting in a large amount of oil on the material surface, which will affect the product quality. During the production process, the upper support needs to be replaced for grinding, which will change the position of the upper support roller and the upper work roller. Specifically, the roller diameter and the rolling line will change, causing the pre-adjusted blowing device to no longer blow the gap between the upper support roller and the upper work roller, so that the rolling oil cannot be blown clean.

[0003] Traditional purging devices have purging nozzles mounted on crossbars, which are ventilated inside. They are fixed to the mill splash guard with a tube head. Each time the position is adjusted, the tube clamps of the crossbar must be loosened, the purging nozzles must be adjusted, and then the tube clamps must be fixed. This is time-consuming and the position is not accurate.

[0004] Therefore, a purging device is needed that can mechanically adjust the purging angle to adapt to changes in the purging surface. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a rolling mill cleaning device that achieves multiple angle adjustment effects through multiple guide plates and limiting blocks, and can be adjusted by a drive motor, which is convenient and labor-saving. This purpose of this utility model is achieved as follows: This utility model proposes a mill cleaning device, including a cleaning head, a front guide plate, and a rear guide plate. A cleaning head is installed on one side of the front guide plate, and front mounting blocks are symmetrically arranged on both sides of the front guide plate. The guide plate and the mounting blocks are connected by a rotating shaft. A rear mounting block is installed on one side of each front mounting block. The rear guide plate is installed between the rear mounting blocks by a rotating shaft. A limit plate is installed on the front guide plate, and a limit block is installed on the rear guide plate to limit the rotation angle of the front guide plate. Both the front and rear mounting blocks have built-in drive motors, and the drive shafts of the drive motors are connected to the front and rear guide plates, respectively.

[0006] Furthermore, it also includes a purge pump, which is connected to the purge head.

[0007] Furthermore, it also includes a control component, which is electrically connected to the purge pump and is used to control the purge pump to turn on and off.

[0008] Furthermore, the control component is electrically connected to the drive motor.

[0009] Furthermore, the rotating shaft is connected to the front guide plate via a bearing.

[0010] Furthermore, the rear guide plate is connected to the rotating shaft via a bearing, and the rear mounting block is also connected to the rotating shaft via a bearing.

[0011] Furthermore, the limiting plate is located on the upper and lower sides of the front guide plate, and the limiting block is located on the upper and lower sides of the rear guide plate and corresponds to the guide plate. The angle between the limiting plates is 60-90 degrees.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the mill blowing device of this invention can flexibly adjust the blowing angle according to different rolling conditions through the adjustable structure of the front guide plate and the rear guide plate, thus meeting the blowing requirements under different conditions. This invention achieves precise adjustment of the blowing angle by controlling the rotation of the guide plate with a drive motor. It is easy to operate and has high adjustment accuracy. The invention also ensures that the blowing angle is within a reasonable range by setting a limit plate and a limit block, avoiding damage to the device caused by excessive rotation, and improving the safety and service life of the equipment.

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to Figure 1-2 This utility model provides a mill cleaning device, including a cleaning head 3, a front guide plate 9, and a rear guide plate 7. The cleaning head 3 is installed on one side of the front guide plate 9, and front mounting blocks 8 are symmetrically arranged on both sides of the front guide plate 9. The front guide plate 9 and the front mounting blocks 8 are connected by a rotating shaft. A rear mounting block 6 is installed on one side of each front mounting block 8. The rear guide plate 7 is installed between the rear mounting blocks 6 by a rotating shaft. A limit plate 4 is installed on the front guide plate 9, and a limit block 5 is installed on the rear guide plate 7 to limit the rotation angle of the front guide plate 9. Both the front mounting block 8 and the rear mounting block 6 have a built-in drive motor 10, and the drive shaft of the drive motor 10 is connected to the front guide plate 9 and the rear guide plate 7, respectively.

[0016] Understandably, the mill purging device also includes a purging pump 11, which is connected to the purging head 3. The purging pump 11 is used to provide pressurized airflow to the purging head 3 to ensure the purging effect. The purging pump 11 uses a high-pressure air pump, which can generate sufficient airflow pressure to ensure a good purging effect. The mill purging device also includes a control component 12, which is electrically connected to the purging pump 11 and is used to control the opening and closing of the purging pump 11. The control component 12 can automatically control the start and stop of the purging pump 11 according to the working state of the mill, thereby improving the automation level of the purging device. The control component 12 uses a programmable controller with multiple control modes, and can select the appropriate purging mode according to different working states of the mill. The control component 12 is electrically connected to the drive motor 10 and can control the speed and direction of the drive motor 10, thereby controlling the rotation angle and rotation speed of the front guide plate 9 and the rear guide plate 7. The control component 12 controls the working state of the drive motor 10 through electrical signals to achieve precise control of the purging device.

[0017] Understandably, the rotating shaft is connected to the front guide plate 9 via bearings to ensure smooth rotation of the front guide plate 9, reduce rotational resistance, and improve rotational accuracy. The bearings are rolling bearings, which have good load-bearing capacity and rotational performance, and can adapt to the harsh working environment of the rolling mill. The rear guide plate 7 is connected to the rotating shaft via bearings, and the rear mounting block 6 is also connected to the rotating shaft via bearings to ensure smooth rotation of the rear guide plate 7, reduce rotational resistance, and improve rotational accuracy. The bearings are rolling bearings, which have good load-bearing capacity and rotational performance, and can adapt to the harsh working environment of the rolling mill. Limiting plates 4 are located on the upper and lower sides of the front guide plate 9, and limiting blocks 5 are located on the upper and lower sides of the rear guide plate 7 and correspond to the guide plates. The angle between the limiting plates 4 is 60-90 degrees. The setting of the limiting plates 4 and limiting blocks 5 can limit the rotation angle of the front guide plate 9, prevent excessive rotation of the front guide plate 9, and ensure the safe operation of the purging device. Specifically, the angle between the limiting plates 4 is 75 degrees. This angle ensures that the front guide plate 9 rotates within an appropriate range, meeting the purging requirements without affecting the normal operation of the rolling mill.

[0018] The working principle of this mill purging device is as follows: like Figure 1As shown, the upper support needs to be replaced for grinding, which causes changes in the positions of the upper support roller 1 and the upper work roller 2. Specifically, the roller diameter and rolling line change, so the blowing angle needs to be changed. When the mill needs to be purged, the control component 12 starts the blowing pump 11, which provides pressurized airflow to the blowing head 3. At the same time, the control component 12 controls the drive motor 10 to rotate, which drives the front guide plate 9 and the rear guide plate 7 to rotate, adjusting the angle of the blowing head 3 so that the blowing head 3 is aligned with the position to be purged. The rotation angle of the front guide plate 9 and the rear guide plate 7 is limited by the limit plate 4 and the limit block 5 to ensure that the blowing head 3 does not rotate to an inappropriate position. After the purging is completed, the control component 12 turns off the blowing pump 11 and stops the purging.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
