Description

Technical Field

[0001] The invention belongs to the technical field of aluminum foil rolling, and in particular relates to a flattening roller cleaning device. Background Art

[0002] In cold rolling production, thin plates are rolled against the plate surface using flattening rollers. During the pressing process, aluminum powder on the surface of the strip adheres to the surface of the flattening rollers. The flattening rollers need to be manually cleaned every time a coil is rolled. Manual cleaning increases the auxiliary rolling time and affects production efficiency.

[0003] To reduce production support time and improve production efficiency, some companies have installed robots to replace manual cleaning. However, the cost of installing robots is relatively high. Therefore, current flattening roller cleaning devices generally use a cylinder or motor to drive a semicircular cleaning mechanism (with cleaning cotton inside) above the flattening roller to clean the roller surface back and forth, replacing manual cleaning of the flattening roller and achieving automatic and rapid cleaning of the roller surface.

[0004] However, the flattening roller presses against the high-temperature strip during operation, which will increase the temperature of the flattening roller. Therefore, the flattening roller often needs to be equipped with a blowing cooling device, which makes it difficult to set up both cleaning and cooling equipment in a limited and narrow space.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0040] Example

[0041] like Figures 1 to 14 As shown, a flattening roller cleaning device includes a mounting base 1 and a cleaning mechanism. The mounting base 1 is arranged on the outside of the flattening roller 9. The mounting base 1 is provided with a frame assembly that can move toward the flattening roller 9. The frame assembly is provided with a base 6 that can reciprocate along the axial direction of the flattening roller 9. The cleaning mechanism includes a mounting block 61 and cleaning cotton 7. One side of the mounting block 61 is fixedly connected to the base 6. The mounting block 61 is arranged in an arc shape. The inner wall of the mounting block 61 is provided with arc-shaped cleaning cotton 7, or a flexible wipe such as a cleaning cloth. The frame assembly can move toward the flattening roller 9 so that the cleaning cotton 7 contacts the flattening roller 9 (such as Figure 2 As shown), after lamination, the flattening roller 9 can be moved back and forth in the axial direction to wipe and clean.

[0042] In the present invention, the cleaning cotton 7 is brought into contact with the flattening roller 9 by controlling the frame assembly to move toward the flattening roller 9, and the cleaning mechanism is simultaneously controlled to move along the axial direction of the flattening roller 9 to achieve comprehensive cleaning. The arc-shaped mounting block 61 is used to cooperate with the mounting of the cleaning cotton 7 to achieve wrapped cleaning of the flattening roller 9, thereby improving cleaning efficiency.

[0043] like Figures 1 to 6 、 Figures 10 to 13 As shown, a bellows 8 is provided on the base 6, and a plurality of air ducts 81 are evenly distributed on one side of the bellows 8. A first connector 82 for introducing a cooling medium (compressed air) is provided at the upper end of the bellows 8. The air ducts 81 pass through the mounting block 61 and the cleaning cotton 7 in sequence, and the end of the air duct 81 is provided inside the cleaning cotton 7.

[0044] In the present invention, the air duct 81 is used to pass through the mounting block 61 and the cleaning cotton 7 in sequence, and the end of the air duct 81 is set inside the cleaning cotton 7, which does not affect the contact and cleaning between the cleaning cotton 7 and the flattening roller 9. At the same time, the air duct 81 can serve as a blowing cooling device and a blowing cleaning device, assisting the cleaning cotton 7 in cleaning and improving cleaning efficiency. At the same time, it can cool the high-temperature flattening roller 9 and lower its operating temperature, thereby reducing the adhesion of aluminum powder and reducing the difficulty of cleaning. Therefore, this design that integrates cleaning and cooling equipment can take into account the functions of cooling the flattening roller 9, blowing cleaning, and cleaning the laminating roller surface, greatly improving cleaning efficiency.

[0045] Furthermore, the inner wall of the mounting block 61 is provided with an arc-shaped mounting groove 611, and the cleaning cotton 7 is matched and arranged in the mounting groove 611. The cleaning cotton 7 is elastic and can be matched and connected in the mounting groove 611 for easy assembly and disassembly.

[0046] like Figure 2 、 Figures 10 to 12 As shown, an oil tank 63 is provided on the upper side of the mounting block 61, and a second connector 641 for introducing oil (white oil, silicone-based oil, etc.) is provided at one end of the oil tank 63. The oil tank 63 is integrally connected to the mounting block 61, and a plurality of oil spray holes 613 are evenly distributed on the oil tank 63 and communicate with the mounting groove 611. The oil spray holes 613 are provided on the upper side of the mounting groove 611. When the cleaning cotton 7 is installed in the mounting groove 611, the external oil supply device is connected to the second connector 641 through a pipeline, and the external air supply device is connected to the first connector 82 through a pipeline. The oil tank 63 and the oil spray holes 613 are used to spray the oil from the upper side onto the cleaning cotton 7. At the same time, the oil gradually penetrates the entire cleaning cotton 7 downwards by penetration and its own weight, and then the cleaning cotton 7 is placed on the surface of the flattening roller 9 for cleaning.

[0047] like Figure 2 、 Figures 10 to 12 As shown, a recovery box 64 is further provided on the bottom side of the mounting block 61, and a recovery chamber 642 is provided in the recovery box 64, which is connected to the bottom side of the mounting groove 611. In this way, the oil can be collected, especially during the wiping process, when the cleaning cotton 7 and the flattening roller 9 contact, there is a certain contact pressure, so the cleaning cotton 7 will be slightly compressed, and the oil will be squeezed out at this time. Therefore, the recovery box 64 can be provided on the bottom side to collect the oil and avoid waste.

[0048] like Figure 11 As shown, the inner wall of the mounting groove 611 is evenly distributed vertically with a plurality of arc-shaped drainage grooves 612. Through the design of the drainage grooves 612, after the cleaning cotton 7 is installed in the mounting groove 611, there is a certain gap between the drainage grooves 612. Therefore, when the oil leaks out, it will flow through the drainage grooves 612 first. The drainage grooves 612 can be used to efficiently drain the oil and make it flow smoothly into the recovery chamber 642 on the bottom side.

[0049] Reference Figure 2 、 Figure 12 and Figure 14The cleaning cotton 7 is evenly distributed with a plurality of first through holes 71, and the middle position of the mounting block 61 is evenly distributed with a plurality of second through holes 62. The spacing between two adjacent first through holes 71 is slightly smaller than the spacing between two adjacent second through holes 62. In addition, the inner diameter of the first through hole 71 is slightly smaller than the outer diameter of the air duct 81. The air duct 81 passes through the second through holes 62 and is disposed in the first through hole 71. Since the cleaning cotton 7 has a certain elasticity, after the cleaning cotton 7 is placed in the mounting groove 611, it is sleeved on the air duct 81 using the first through hole 71 to achieve a fixed installation. This makes it difficult for the cleaning cotton 7 to fall out of the mounting groove 611. At the same time, this plug-in connection method makes it easy to replace and clean the cleaning cotton 7 later.

[0050] like Figures 1 to 14 As shown, the frame assembly includes a first support base 4 and a second support base 5, which are connected by two connecting rods 54. A first slider 44 is provided on one side of the first support base 4, and a second slider 51 is provided on one side of the second support base 5. The mounting base 1 is configured as a U-shape, with guide rails 11 provided on both sides of the mounting base 1. A first slide 45 is provided on the first slide 44, and a second slide 52 is provided on the second slide 51. The first slide 44 slides on the guide rail 11 through the first slide 45, and the second slide 51 slides on the guide rail 11 through the second slide 52, thereby achieving sliding guidance of the frame assembly. Two first cylinders 2 are provided on the outside of the mounting base 1, and a first piston rod 21 is provided inside the first cylinder 2. The two first cylinders 2 are connected to the first slider 44 and the second slider 51 respectively through the first piston rod 21 for transmission. The expansion and contraction of the first cylinder 2 drives the frame assembly toward or away from the flattening roller 9.

[0051] like Figures 1 to 14 As shown, a screw rod 31 is rotatably provided between the first support base 4 and the second support base 5. One end of the screw rod 31 is connected to the motor 3, which is fixed to the first support base 4. A screw nut 32 is provided on the screw rod 31, which is connected to the mounting plate 66, and the mounting plate 66 is fixedly connected to the base 6. A plurality of guide seats 67 are provided on both sides of the mounting plate 66. Guide sleeves 671 are provided in the guide seats 67, and the guide sleeves 671 are slidably arranged against the connecting rod 54. The guide sleeves 671 and the connecting rod 54 are used to achieve guidance. At the same time, the structure of the screw rod 31 and the screw nut 32 realizes the movement of the base 6, thereby linking the cleaning mechanism to move along the axial direction of the flattening roller 9.

[0052] like Figures 4 to 9As shown, connecting blocks 41 are symmetrically provided on both sides of the first support seat 4, a U-shaped first frame 42 is provided between the two connecting blocks 41, and a first bearing seat 43 is detachably provided inside the first frame 42; the second support seat 5 is set to be U-shaped, and a second bearing seat 53 is detachably provided inside the second support seat 5, and the two ends of the screw rod 31 are respectively connected to the inside of the first bearing seat 43 and the second bearing seat 53 to realize the installation of the screw rod 31.

[0053] like Figures 4 to 9 As shown, the first support base 4 is configured in a U shape, and the motor 3 is disposed inside the first support base 4, fitting snugly against the inner wall of the first support base 4. One side of the motor 3 is fixed to the first support base 4 with screws, achieving a protective installation of the motor 3. The motor 3 is connected to the screw rod 31 via a coupling 33, which is disposed between two connecting blocks 41, achieving a protective installation of the coupling 33. This mounting structure allows for the ingenious installation and protection of the bearing seat and motor 3.

[0054] like Figure 6 As shown, the screw nut 32 is connected to the hollow flange 68 by screws, and the hollow flange 68 is fixed to the mounting plate 66. The screw nut 32 is arranged between the guide seats 67 on both sides. The screw 31 and the screw nut 32 are connected in a cooperative manner, and the screw 31 passes through the interior of the hollow flange 68. The guide seat 67 adopts a structure with a notch, and the guide sleeve 671 also adopts a notch guide sleeve 671, which facilitates the disassembly and assembly of the guide sleeve 671.

[0055] like Figures 5 to 7 、 Figure 10 、 Figure 12 As shown, three triangularly distributed connecting holes 65 are evenly distributed on the base 6, and four guide seats 67 are provided on the mounting plate 66. Two guide seats 67 are provided on one side, and the guide seats 67 on the same side are spaced apart. An opening is provided between the two guide seats 67 for passing a bolt 69, and the bolt 69 is connected to the connecting hole 65, thereby realizing the connection between the base 6 and the mounting plate 66.

[0056] The present invention also provides a more efficient cleaning method, that is, in the process of using the cleaning cotton 7 to stick to the flattening roller 9 for cleaning, the bellows 8 is connected to an external exhaust device to provide a negative pressure environment at the position of the cleaning cotton 7. Because the cleaning cotton 7 sticks to the surface of the flattening roller 9 and is squeezed during cleaning, part of the oil will seep down and be collected in the collection box 64 at this time, but part of the oil is inevitably squeezed and stuck to the surface of the flattening roller 9, especially at the boundary position where the flattening roller 9 and the cleaning cotton 7 contact, the oil is easy to seep out. After the negative pressure suction function is set, when the cleaning cotton 7 is squeezed for cleaning, the internal negative pressure environment will give the oil a suction force, thereby helping the oil to remain on the cleaning cotton 7, reducing the situation where the oil on the cleaning cotton 7 is squeezed and seeped onto the surface of the flattening roller 9.

[0057] like Figures 15 to 17 As shown, the air duct 81 is provided with a stepped valve port 811, which is fitted with a check valve 86. A plug 84 is connected to the inner wall of the outer end of the stepped valve port 811. The plug 84 is hollow, and a spring 85 is connected between the plug 84 and the check valve 86, which forces the check valve 86 to close the air duct 81. Several inclined overflow channels 83 are evenly distributed around the circumference of the air duct 81. The ends of the overflow channels 83 are located at the intersection of the mounting groove 611 and the cleaning cotton 7, and the interior of the overflow channels 83 communicates with the interior of the air duct 81. Furthermore, a sealing ring 621 is provided on the outer wall of the air duct 81, on the inner wall of the second through hole 62, to enhance the seal.

[0058] When the cleaning cotton 7 is ready to work, oil is introduced into the upper side to soak the cleaning cotton 7, and at the same time, the air duct 81 blows air. The pressure at this time is recorded as P1. The value of P1 is less than the pressure of the spring 85, which is insufficient to open the one-way valve 86. Due to the action of the spring 85, the one-way valve 86 is closed, and most of the wind force is blown out from the overflow channel 83, directly acting on the inside of the cleaning cotton 7, thereby evenly distributing the oil, allowing the cleaning cotton 7 to be more evenly soaked in the oil, and absorbing the oil. Under this pressure, the oil cannot be blown out from the inside of the cleaning cotton 7 to splash. This method, combined with the oil discharge from the upper oil spray hole 613, realizes the uniform absorption of the oil by the cleaning cotton 7.

[0059] When the cleaning cotton 7 contacts the flattening roller 9 for operation, the upper side stops entering the oil to soak the cleaning cotton 7, and at the same time the air duct 81 performs suction. Due to the action of the spring 85, the one-way valve 86 is continuously closed. During suction, the wind can only be sucked from the overflow channel 83 and directly act on the inside of the cleaning cotton 7. When the cleaning cotton 7 is squeezed for cleaning, the internal negative pressure environment will give the oil a suction force, thereby assisting the oil to remain on the cleaning cotton 7 and reducing the situation where the oil on the cleaning cotton 7 is squeezed out and seeps onto the surface of the flattening roller 9. This method can ensure that the cleaning cotton 7 is soaked in oil as much as possible, improve the cleaning effect, and at the same time reduce the situation where the cleaning cotton 7 is squeezed and causes oil to seep out during the cleaning process.

[0060] When the air duct 81 blows air to clean or cool the surface of the flattening roller 9, the cleaning cotton 7 moves away from the flattening roller 9, and the air duct blows air. At this time, the pressure is recorded as P2. The value of P2 must be greater than the pressure of the spring 85, thereby pushing open the one-way valve 86. Most of the wind force is blown out from the front end of the air duct 81 to act on the flattening roller 9, while a small part of the wind force is blown out from the overflow channel 83, but will be hindered by the cleaning cotton 7, thereby ensuring that most of the wind force is blown out from the end of the air duct 81 to achieve blowing cleaning or cooling.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
