Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil rolling mills, in particular to an aluminum foil rolling mill spray device with a negative pressure oil absorption function. 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 coiling, and use oil mist spray to clean the aluminum powder on the surface of the aluminum foil to a certain extent, thereby reducing the possibility of black silk and black lines.

[0004] However, in actual application, there are the following problems: during the oil mist spraying process, due to the natural diffusion of the oil mist, the oil mist at the spraying point cannot be fully used to clean the surface of the aluminum foil. Although part of it can be collected and filtered for reuse, another part of it diffuses to areas that cannot be collected, which not only causes the loss of oil mist, but also causes the deterioration of the working environment;

[0005] In view of this, there is an urgent need for an aluminum foil rolling mill spray device with a negative pressure oil absorption function to solve the above-mentioned problem. Utility Model Content

[0023] 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.

[0024] Embodiment 1

[0025] Please see attached Figure 1-3

[0026] A spray pipe 1, a spray pipe fixing frame 2, a negative pressure oil absorption component 3 and a height adjustment component 4, wherein the spray pipe 1 is detachably connected to the spray pipe fixing frame 2, the negative pressure oil absorption component 3 is fixedly connected to the spray pipe fixing frame 2 through the height adjustment component 4, and L-shaped ear plates 5 fixedly connected thereto are provided at both ends of the spray pipe fixing frame 2, one of the L-shaped ear plates 5 is connected to a servo motor, and the other L-shaped ear plate 5 is hinged to the aluminum foil rolling mill frame;

[0027] The spray tube 1 is fixed by the spray tube fixing frame 2. Considering that there are many ways to fix the spray tube 1 by the spray tube fixing frame 2 and the technology is mature (for example, by arranging a buckle for binding the spray tube 1 in the spray tube fixing frame 2, or by placing the spray tube 1 in the spray tube fixing frame 2 and fixing it by buckling, etc.), no further details are given. The actual distance between the negative pressure oil absorption component 3 and the spray tube 1 is adjusted by setting the height adjustment component 4, and the range of negative pressure oil absorption is indirectly controlled. The angle of the entire spray tube fixing frame 2 is controlled by setting the L-shaped ear plate 5. It is worth noting that the L-shaped ear plate 5 can achieve the actual distance between the entire spray tube fixing frame 2 and the aluminum foil by adopting a sleeve plate structure.

[0028] Specifically, the negative pressure oil suction assembly 3 includes two groups of arc plates 30, two groups of negative pressure oil suction heads 31, an arc connecting plate 32 and an arc adjustment assembly 33. The two groups of arc plates 30 are hinged to the arc connecting plate 32 of the Haloxylon ammodendron in symmetrical positions. The two groups of negative pressure oil suction heads 31 are respectively fixedly connected to one end of the two groups of arc plates 30 away from the arc connecting plate 32. The arc adjustment assembly 33 is fixedly connected to the arc connecting plate 32, and it contacts the two groups of arc plates 30 respectively.

[0029] Specifically, the curvature adjustment assembly 33 includes a curvature adjustment housing 330, a rotating shaft 331, a curvature adjustment handle 332, at least one set of gears 333, a first tooth plate 334 and a second tooth plate 335. The upper side wall of the curvature adjustment housing 330 is provided with a connecting block 3300 fixedly connected to the arc connecting plate 32. The rotating shaft 331 is located in the curvature adjustment housing 330, one end of which is rotatably connected to the inner wall of the curvature adjustment housing 330, and the other end is connected to the curvature adjustment handle 33 2, and the curvature adjustment handle 332 is threadedly connected to the curvature adjustment housing 330, at least one set of the gears 333 is keyed to the rotating shaft 331, one end of the first tooth plate 334 and the second tooth plate 335 respectively pass through the side walls of both sides of the curvature adjustment housing 330 and mesh with the gears 333, and the ends of the first tooth plate 334 and the second tooth plate 335 away from the curvature adjustment housing 330 are in contact with the concave side walls of the two arc plates 30 respectively;

[0030] Considering that when the negative pressure oil suction head 31 is too close or too far from the spray pipe 1, the oil mist spray range may be insufficient or too large, which reduces the cleaning effect of the oil mist or causes waste of the oil mist. The two sets of arc plates 30 are respectively hinged at the two ends of the arc connecting plate 32, so that the coverage formed by the two sets of arc plates 30 can be adjusted to a certain extent, that is, the distance between the negative pressure oil suction head 31 and the spray pipe 1 can be changed to a certain extent. The specific adjustment method is to drive the rotation of the rotating shaft 331 and the gear 333 thereon by the rotation of the arc adjustment handle 332, and the meshing between the gear 333 and the first tooth plate 334 and the second tooth plate 335 The first tooth plate 334 and the second tooth plate 335 work together to move in opposite directions. For example, the first tooth plate 334 and the second tooth plate 335 move toward the direction close to the rotating shaft 331 at the same time, which will cause the two sets of arc plates 30 to move in the direction of contraction, thereby changing the distance between the negative pressure oil suction head 31 and the spray pipe 1, thereby achieving the purpose of narrowing the oil mist spray range. It should be noted that in order to avoid the situation where the oil mist sprayed by the spray pipe 1 is sucked away by the negative pressure oil suction head 31 before it contacts the aluminum foil, the vertical height of the negative pressure oil suction head 31 should be higher than the vertical height of the spray pipe 1, and the direction in which the negative pressure oil suction head 31 absorbs the oil mist should be toward the side away from the spray pipe 1.

[0031] Specifically, the height adjustment component 4 includes a height adjustment housing 40, a height adjustment tooth plate 41, a height adjustment shaft 42, at least one set of height adjustment gears 43 and a height adjustment handle 44, the height adjustment housing 40 is fixedly connected to the upper side wall of the spray tube fixing frame 2, one end of the height adjustment tooth plate 41 is fixedly connected to the lower side wall of the arc adjustment housing 330, and the other end passes through the upper side wall of the height adjustment housing 40 and is slidably connected thereto, the height adjustment shaft 42 is located in the height adjustment housing 40, one end of which is rotatably connected to the inner wall of the height adjustment housing 40, and the other end is fixedly connected to the height adjustment handle 44, and the height adjustment handle 44 is threadedly connected to the height adjustment housing 40, at least one set of height adjustment gears 43 is keyed to the height adjustment shaft 42, and the height adjustment gear 43 is meshedly connected to the height adjustment tooth plate 41;

[0032] Taking into account the problem that the adjustable range of the curvature adjustment component 33 may be insufficient in actual applications, in order to expand the upper limit of the adjustable range, a height adjustment component 4 is additionally provided on the basis of the curvature adjustment component 33. The height adjustment shaft 42 and the height adjustment gear 43 thereon are driven to rotate by the height adjustment handle 44, and the actual application length of the height adjustment tooth plate 41 located outside the height adjustment housing 40 is changed by the meshing connection, thereby achieving the purpose of expanding the upper limit of the adjustable range of the curvature adjustment component 33. Taking into account that in actual applications, the position between the negative pressure oil suction head 31 and the aluminum foil does not need to be adjusted frequently, the height adjustment handle 44 and the curvature adjustment handle 332 are not electrically operated, but it does not mean that they can only be operated manually.

[0033] Specifically, the height adjustment handle 44 and the curvature adjustment handle 332 are provided with locking pins for locking their positions; considering that in actual applications, the arc plate 30 may have too much weight, and then the height adjustment gear 43 and the gear 333 may drive the height adjustment handle 44 and the curvature adjustment handle 332 to rotate in the opposite direction through the meshing action, the height adjustment handle 44 and the curvature adjustment handle 332 are provided with locking pins for locking the position (not shown in the figure), and other technically mature means may also be used to replace the locking pin to lock the height adjustment handle 44 and the curvature adjustment handle 332.

[0034] Specifically, the negative pressure oil suction head 31 is externally connected to a negative pressure oil suction hose 310 and a negative pressure machine matched therewith.

[0035] Specifically, a plurality of oil seepage holes 311 are provided on the side wall of the negative pressure oil suction head 31 close to the concave surface of the arc plate 30; considering that the concave surface of the arc plate 30 may condense into oil droplets and drip onto the aluminum foil when in contact with the sprayed oil mist, oil seepage holes 311 are provided on the side of the negative pressure oil suction head 31 close to the concave surface of the arc plate 30 to recover such oil droplets.

[0036] The second tooth plate 335 and the first tooth plate 334 are rectangular plates, and the length of the second tooth plate 335 is greater than that of the first tooth plate 334. Considering that the first tooth plate 334 and the second tooth plate 335 are on horizontal planes at different heights, there is a drop in the contact position with the arc plate 30. In order to avoid the situation where the two groups of arc plates 30 are tilted, the drop of the contact point is corrected by adopting different actual lengths of the first tooth plate 334 and the second tooth plate 335.

[0037] Specifically, the length of the second tooth plate 335 is the same as that of the first tooth plate 334, and the second tooth plate 335 is L-shaped; considering that the first tooth plate 334 and the second tooth plate 335 are on horizontal planes at different heights, there is a gap in the contact position between them and the arc plate 30. In order to avoid the situation where the two groups of arc plates 30 are tilted, the second tooth plate 335 at a lower position adopts an L-shaped plate setting to compensate for the gap.

[0038] 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.
