Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil manufacturing, in particular to an aluminum foil ironing roller blowing device. Background Art

[0002] Aluminum foil rolling mill is a device used to turn a billet with a thickness of about 0.22mm into aluminum foil with a thickness of less than 0.02mm after several rolling processes. In the production process, the existing high-speed aluminum foil rolling mill usually relies on ironing rollers to assist in coiling to prevent the occurrence of layer-by-layer phenomenon during the coiling process. However, due to the aluminum powder on the surface of the aluminum coil, it is easy to cause aluminum powder accumulation at the ironing roller during the production process, forming defects such as black wire and black line;

[0003] In order to solve the above problems, most existing aluminum foil rolling mills will spray the aluminum foil by setting a spray pipe at the front end of the aluminum foil winding, and use oil mist spraying to clean the aluminum powder on the surface of the aluminum foil to a certain extent. However, after the sprayed aluminum foil contacts the ironing roller, the oil droplets formed by the spray will adhere to the ironing roller and be transferred back to other aluminum foil surfaces during the subsequent rotation process. If it is not cleaned in time, there will be too many oil droplets on the surface of the aluminum foil, and a large amount of oil on the surface of the aluminum foil will seriously affect the quality of the surface of the aluminum foil;

[0004] In view of this, there is an urgent need for an aluminum foil ironing roller blowing device that can solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The frame 1 is provided with two groups, and the two ends of the ironing roller are movably connected to the two groups of the frame 1 respectively, and an annular groove 10 is provided on the curved side wall of the frame 1, a rotating component 2 is movably connected in the annular groove 10, and a purge pipe component 3 movably connected to the rotating component 2 is provided outside the rotating component 2.

[0026] Specifically, the rotating assembly 2 includes an annular turntable 20, a fixed seat 21, a locking assembly 22 and an adjusting handle 23. The annular turntable 20 is rotatably connected to the annular groove 10. The fixed seat 21 is fixedly connected to the curved side wall of the annular turntable 20, and a through cavity 210 is provided thereon. The locking assembly 22 is located in the through cavity 210. One end of the adjusting handle 23 passes through the through cavity 210 away from the side wall of the annular turntable 20 and is movably connected to the locking assembly 22, and the adjusting handle 23 is threadedly connected to the fixed seat 21.

[0027] Specifically, a plurality of adjusting bolts 11 are provided on the side wall of the frame body 1 away from the ironing roller, the adjusting bolts pass through the side wall of the annular groove 10 and contact the annular rotating disk 20, and the adjusting bolts 11 are threadedly connected to the frame body 1;

[0028] When in use, the purge pipe assembly 3 passes through the locking notch 22000 of one locking block 220 until it reaches the locking notch 22000 of the other locking block 220. Then, the fixing seat 21 and the annular turntable 20 can be driven to rotate along the annular groove 10 by the purge pipe assembly 3. After adjusting the purge pipe assembly 3 to a suitable position, the position of the annular turntable 20 can be fixed by adjusting the bolt 11 to complete the preliminary installation. After ventilation, the purge pipe assembly 3 is used to guide the gas to the surface of the ironing roller, and the oil droplets in the middle area of ​​the ironing roller and the aluminum powder that may be wrapped in the oil droplets are blown to the two ends of the ironing roller, and the oil droplets are thrown off by the centrifugal force generated when the ironing roller rotates.

[0029] Among them, through the setting of the annular groove 10 and the annular turntable 20, the free rotation of the annular turntable 20 can be ensured, and the purpose of adjusting the specific position of the purge pipe assembly 3 can be achieved by using the adjusting bolt 11. The setting of the adjusting handle 23 and the locking assembly 22 can change the vertical distance between the locking assembly 22 and the surface of the ironing roller through the adjusting handle 23, that is, the height of the purge pipe assembly 3 can be freely adjusted to achieve the best purge effect.

[0030] Specifically, the locking assembly 22 includes a locking block 220, an arc block 221, a locking pin 222 and at least one spring 223. The locking block 220 is provided with a locking notch 22000. The arc block 221 is located in the locking notch 2200. Two ends of at least one spring 223 are respectively fixedly connected to the convex surface of the arc block 221 and the inner wall of the locking notch 2200, and the locking pin 222 is detachably connected to the side wall of the locking notch 2200 close to the arc block 221.

[0031] The clamping of the purge tube assembly 3 is achieved by the mutual cooperation of the arc block 221 provided in the locking block 220 and the locking notch 22000 on the locking block 220, wherein the spring 223 is simply provided to prevent the arc block 221 from falling when the transverse purge tube assembly 3 is not clamped. Therefore, the arc block 221, the locking pin 222 and the spring 223 can also be combined into a clamping block for clamping the purge tube assembly 3. At the same time, the arc-shaped upper inner wall of the locking notch 22000 in the accompanying drawings is also provided to fit with the tubular structure, and does not form a restriction on the locking notch 22000. In fact, if a rectangular tubular structure is adopted, the upper inner wall of the locking notch 22000 can also be set to a rectangle.

[0032] Specifically, the purge pipe assembly 3 includes a transverse main pipe 30, a hose 31 and at least two groups of tortuous purge pipes 32. One end of the transverse main pipe 30 is movably connected to the locking assembly 22, and the other end is detachably connected to the hose 31 after passing through another locking assembly 22. The two groups of tortuous purge pipes 32 are connected to the transverse main pipe 30 in symmetrical positions.

[0033] Specifically, the transverse main pipe 30 is provided with a plurality of connecting holes 300, and the connecting holes 300 are provided with matching plugs 301, and the zigzag purge pipe 32 is detachably connected to the connecting holes 300; the plurality of connecting holes 300 provided on the transverse main pipe 30 can be used to install the zigzag purge pipe 32 to achieve the purpose of adjusting the position or number of the zigzag purge pipe 32, and the unused connecting holes 300 can be closed by the plugs 301. It should be noted that, considering that the ironing roller is rarely replaced in actual applications (even if it is replaced, it is mostly replaced with an ironing roller of the same size), the position of the zigzag purge pipe 32 does not need to be disassembled most of the time. Therefore, the zigzag purge pipe 32 can also be directly fixed to the transverse main pipe 30 by welding.

[0034] Specifically, the angle between the end of the zigzag purge pipe 32 away from the transverse main pipe 30 and the ironing roller is 0-90°; the angle between the zigzag purge pipe 32 and the transverse main pipe 30 is to ensure that the wind blown by the zigzag purge pipe 30 can effectively blow the oil droplets on the ironing roller to both ends thereof;

[0035] At the same time, in order to quickly blow away the oil droplets, the evaporation of the oil droplets can be accelerated and the volume of the oil droplets can be reduced by increasing the temperature of the gas blown out by the purge pipe assembly 3. However, it should be noted that the temperature should not be too high. If the temperature is too high, not only the protection problem needs to be considered, but also the situation that the oil droplets are completely evaporated due to excessive temperature, causing the aluminum powder wrapped in them to stick completely to the aluminum foil.

[0036] Specifically, the transverse main pipeline 30 is provided with a bifurcated purge pipe 33 matched therewith; Figure 1 The purging method in the embodiment may easily result in a situation where the unpurged area in the middle of the ironing roller is too large, so a forked purging pipe 33 is provided, and the forked purging pipe is installed in the middle position of the transverse main pipe 30, so that the oil droplets in the middle position of the ironing roller are blown to both sides and then blown to both ends of the ironing roller through the zigzag purging pipe 32.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
