Description

Technical Field

[0001] The present invention relates to the technical field of aluminum foil heat treatment, and specifically discloses an energy-saving annealing treatment device for light foil processing. Background Art

[0002] Light foil is an aluminum foil whose surface is not subjected to treatments such as coating, printing, embossing, etc., and is also called plain aluminum foil. During the production and processing of light foil, in order to improve the material properties of the light foil, eliminate internal stress and enhance corrosion resistance, it is necessary to anneal the wound light foil coil.

[0003] For the existing annealing treatment operation of aluminum foil, usually, the aluminum foil coil is first hoisted onto the placement rack by a hoisting device, then the gate of the annealing furnace is opened, and then the entire placement rack is pushed into the annealing furnace for annealing treatment. After the annealing treatment is completed, the gate needs to be opened again to push out the entire placement rack.

[0004] The utility model patent with the application number 201920469438.2 discloses an aluminum coil circulating annealing furnace, including an annealing furnace body. External rotating motors are fixedly installed on the right side of the front and the right side of the back of the annealing furnace body. For this aluminum coil circulating annealing furnace, the rotating rod is driven to rotate by the internal rotating motor, so that the gear rotates. Through the meshing of the gear and the rack, and through the sliding connection of the slider and the slide rail, the feeding plate can move horizontally left and right. When the furnace door is opened, the internal rotating motor can be started to move the feeding plate to the right side of the annealing furnace body. After placing the aluminum coil to be annealed on the feeding plate, the feeding plate is then retracted into the interior of the annealing furnace body, thus completing the feeding of the annealing furnace. Through the improvement of the feeding method, this annealing furnace has a larger feeding angle, is more convenient and faster, and further improves the feeding efficiency; however, for this type of annealing furnace structure, the entire gate needs to be opened during the process of feeding and discharging, resulting in serious heat loss inside the furnace body. When annealing the next batch of aluminum coils, it is necessary to operate at a higher power, resulting in a higher annealing treatment cost for the entire aluminum coils. In addition, when annealing the aluminum coils, they are placed on the placement rack without moving, and the distances between the heat source and different aluminum coils on the placement rack are different, resulting in uneven heating of the aluminum coils and affecting the annealing treatment effect of the aluminum coils in the same batch. Therefore, in view of the technical problems existing in the annealing treatment of aluminum foil coils by the traditional annealing furnace, the present application proposes a newly designed energy-saving annealing treatment device for light foil processing. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy-saving annealing treatment device for light foil processing to solve the problems of a large amount of heat loss caused by the opening of the gate during the feeding and discharging processes of the existing aluminum coil circulating annealing furnace, and the uneven annealing caused by the unequal distances between the heat source and the aluminum coils in the same batch.

[0006] The present invention is achieved through the following technical solutions: An energy-saving annealing treatment device for light foil processing, comprising two gantry frames symmetrically arranged left and right. There is a lifting plate arranged between the two gantry frames, and a hydraulic cylinder connected to the lifting plate is arranged on the gantry frame. A plurality of stepped round openings that are large at the top and small at the bottom are arranged in rows on the upper surface of the lifting plate. An annealing furnace cover concentric with the stepped round openings is arranged on the upper surface of the lifting plate. A sealing round plate that moves vertically and seals the stepped round openings is connected in the annealing furnace cover through a guide rod; A rotating cylinder is rotatably arranged directly below the lifting plate, and one end of the rotating cylinder is connected to a power device. A plurality of rows of aluminum foil roll lifting mechanisms are evenly arranged on the outer side surface of the rotating cylinder, and each row of aluminum foil roll lifting mechanisms is aligned with the stepped round openings on the lifting plate. The aluminum foil roll lifting mechanism includes a heat-insulating end plate adapted to the lower end of the stepped round opening, and a positioning member for penetrating the center of the aluminum foil roll is arranged at the center of the heat-insulating end plate; A feeding mechanism and a discharging mechanism are respectively arranged on the front and rear sides of the rotating cylinder. The feeding mechanism and the discharging mechanism have the same structure and are arranged to move closer to or away from the rotating cylinder under the action of a pushing mechanism or a traction mechanism.

[0007] During the operation of the energy-saving annealing treatment device for light foil processing disclosed in the present invention, the aluminum foil roll is horizontally pushed towards the rotating cylinder by the feeding mechanism, so that the aluminum foil roll lifting mechanism in the horizontal state on the rotating cylinder lifts the aluminum foil roll. Then, the rotating cylinder is rotated upward by 90° through the power device, so that the aluminum foil roll is vertically oriented towards the stepped round opening, and then the hydraulic cylinder is started to push the lifting plate downward. During the downward movement of the lifting plate, the top end of the positioning member penetrating the center of the aluminum foil roll will abut against the sealing round plate, thereby pushing the sealing round plate upward, opening the stepped round opening, and then the aluminum foil roll smoothly extends into the annealing furnace cover until the heat-insulating end plate cooperates with the stepped round opening to seal the entire annealing furnace cover. After sealing, the aluminum foil roll is annealed through the high-temperature environment in the annealing furnace cover.

[0008] After the aluminum foil roll is annealed, the hydraulic cylinder is reversely started to lift the lifting plate upward. During the upward movement of the lifting plate, the aluminum foil roll will be drawn out from the stepped round opening. However, since the diameter of the aluminum foil roll is slightly smaller than the diameter of the stepped round opening and the annular gap between the two is small, and at the same time, heat accumulates at the upper end of the inner cavity of the annealing furnace cover, only a small amount of heat flows out from the annular gap. When the aluminum foil roll is completely drawn out from the stepped round opening, the sealing round plate will quickly seal the stepped round opening under the action of its own gravity and the guiding of the guide rod, which can avoid the heat flow rate in the annealing furnace cover.

[0009] Finally, the power device is started again to rotate and switch the next set of aluminum foil roll lifting mechanisms loaded with aluminum foil rolls to the uppermost vertical state and align them with the annealing furnace cover up and down, and repeat the above steps to push the aluminum foil roll into the annealing furnace cover, and the annealed aluminum foil roll can be taken off through the discharging mechanism.

[0010] As a further setting of the above solution, the annealing furnace cover is cylindrical and its lower end is connected to the stepped circular opening. The annular wall of the annealing furnace cover is composed of an inner heat insulation layer and an outer panel layer. A heat source for heating the aluminum foil roll is provided on the inner wall of the annealing furnace cover. The structural design of the above annealing furnace cover can achieve a good heat insulation effect, avoid heat loss through heat conduction inside, and combined with the active heating of the heat source, it can enable the aluminum foil roll to quickly rise to the annealing temperature for heat treatment when it enters.

[0011] As a further setting of the above solution, a guide cylinder acting on the guide rod is provided at the top of the annealing furnace cover. The sealing circular plate is connected to the lower end of the guide rod, and the sealing circular plate is arranged in a stepped shape. The interaction between the guide cylinder and the guide rod above can make the sealing circular plate move vertically up and down, and the stepped sealing circular plate design enables it to press and seal the stepped circular opening under its own gravity to avoid heat outflow.

[0012] As a further setting of the above solution, the positioning member is a central rod. The heat insulation end plate is fixedly connected to the rotating cylinder, and the central rod is fixedly connected to the center of the heat insulation end plate. The above is the first specific solution of the aluminum foil roll lifting mechanism in the present invention, which can pass through the aluminum foil roll for positioning, and the heat insulation end plate can support the aluminum foil roll.

[0013] As a further setting of the above solution, the positioning member includes an outer shaft cylinder fixedly connected to the heat insulation end plate. A pressing rod with its top end extending is concentrically arranged in the outer shaft cylinder, and a spring is connected between the lower end of the pressing rod and the heat insulation end plate. A plurality of strip-shaped openings are evenly arranged on the outer circular surface of the outer shaft cylinder. Tightening strips extending into the outer shaft cylinder are arranged in the strip-shaped openings. A spring ring is sleeved between the plurality of tightening strips. An inclined surface pressing opening is arranged at the inner end of the tightening strip. A pressing inclined surface block matching the inclined surface pressing opening is arranged on the pressing rod.

[0014] As a further setting of the above solution, a transmission cavity is opened inside the rotating cylinder. A rotating rod is arranged in the transmission cavity, and one end of the rotating rod is connected to a rotating motor. A row of driving bevel gears is arranged on the rotating rod. A rotating connection cylinder aligned with each heat insulation end plate is arranged on the outer side surface of the rotating cylinder. A transmission shaft extending into the transmission cavity through the rotating connection cylinder is connected to the heat insulation end plate. A driven bevel gear meshing with the corresponding driving bevel gear is arranged on the transmission shaft.

[0015] The above is the second specific solution of the aluminum foil roll lifting mechanism in the present invention. It can not only position and support the aluminum foil roll, but also during the downward movement of the annealing furnace cover, the pressing rod will come into contact with the sealing circular plate immediately, causing the pressing rod to push downward. Under the action of the pressing inclined block and the inclined surface pressing opening, the tensioning strips on the outer shaft tube will expand outward synchronously, thereby centering and tensioning the aluminum foil roll. In addition, when the aluminum foil roll completely extends into the annealing furnace cover, driven by the rotation of the rotating motor and the meshing of the bevel gears, the aluminum foil roll will slowly rotate at the center of the annealing furnace cover, so that it can evenly contact the heat emitted by the heat source, improving the uniformity of the annealing treatment and ensuring the effect of the annealing treatment of the aluminum foil roll.

[0016] As a further setting of the above solution, side plates and support plates are respectively arranged on the two gantry frames. The power device is arranged on the side plate and is connected to the rotating cylinder through a rotating shaft. The other end of the rotating cylinder is provided with a hollow shaft for extending the rotating rod. A bearing seat connected to the hollow shaft is arranged on the support plate. The rotating motor is installed at the outer end of the hollow shaft and is connected to the rotating rod.

[0017] As a further setting of the above solution, the power device is composed of a motor and a worm and worm gear reduction mechanism.

[0018] The above is one of the specific installation solutions of the rotating cylinder and the aluminum foil roll lifting mechanism in the present invention, enabling the rotating cylinder to be rotatably arranged between the lower ends of the two gantry frames and being driven by a power device composed of a motor and a worm and worm gear reduction mechanism, which can not only make the rotating cylinder rotate stably, but also stably lock the adjusted state after rotation adjustment.

[0019] As a further setting of the above solution, both the loading mechanism and the unloading mechanism include a moving seat. An inclined surface support adjustment assembly aligned with each aluminum foil roll lifting mechanism is arranged on the moving seat. The inclined surface support adjustment assembly includes two groups of inclined surface support blocks that are mirror-symmetrical left and right and are arranged in a staggered manner. A transmission mechanism for driving the two groups of inclined surface support blocks to approach or move away from each other is arranged in the moving seat.

[0020] As a further setting of the above solution, the transmission mechanism includes a transmission rod arranged in the internal cavity of the moving seat. One end of the transmission rod is connected to an adjustment motor. Opposite threads are provided on the transmission rod and are aligned with the inclined surface support adjustment assembly. The opposite threads are divided into two sections and are arranged with opposite spiral directions. Screw hole blocks extending into the cavity through linear openings are arranged at the lower ends of the inclined surface support blocks, and the screw hole blocks are arranged in cooperation with the opposite threads.

[0021] The above is the specific design scheme of the loading mechanism and the unloading mechanism in the present invention. By means of the transmission mechanism, the two sets of inclined plane support blocks are controlled to move closer to or away from each other, so that the aluminum foil coils placed on the two sets of inclined plane support blocks can be adjusted at different heights. At the same time, this structural design can also be applicable to aluminum foil coils with different coil diameters, enabling the entire loading and unloading mechanism to accurately load the aluminum foil coils onto the aluminum foil coil lifting mechanism, or unload the aluminum foil coils after the annealing treatment from the aluminum foil coil lifting mechanism.

[0022] Compared with the prior art, the present invention has the following beneficial effects: When the energy-saving annealing treatment device disclosed in the present invention is used for annealing treatment of aluminum foil coils, whether the aluminum foil coils enter or exit the annealing furnace hood, the stepped circular opening can communicate with the outside with a smaller annular gap. Coupled with the heat being concentrated at the top of the annealing furnace hood, it will greatly reduce the heat loss inside the annealing furnace hood during the feeding and discharging processes, having the advantages of energy conservation and environmental protection.

[0023] When the energy-saving annealing treatment device disclosed in the present invention performs annealing treatment on aluminum foil coils, the aluminum foil coils are concentrically placed in the annealing furnace hood, enabling the aluminum foil coils to be evenly heated. Coupled with the further improved design of the aluminum foil coil lifting mechanism, when the aluminum foil coils are heat-treated in the annealing furnace hood, their slow rotation can be controlled, so that the heat source on the inner wall of the annealing furnace hood can evenly heat the aluminum foil coils, improving the annealing heat treatment effect of the aluminum foil coils.

[0024] During the process of loading and unloading aluminum foil coils in the energy-saving annealing treatment device disclosed in the present invention, it is only necessary to push the aluminum foil coils to be docked with the aluminum foil coil lifting mechanism on the rotating cylinder through the loading and unloading mechanisms, and then the aluminum foil coils can be adjusted to be aligned with the annealing furnace hood through the rotation adjustment of the rotating cylinder, making the entire loading and unloading process of the aluminum foil coils very simple and fast. There is no need to use lifting equipment to lift them onto the storage rack, improving the annealing treatment efficiency of the aluminum foil coils and ensuring the safety of the loading and unloading process.

[0025] The loading mechanism and the unloading mechanism in the present invention, through a special structural design, can, during the process of loading or unloading aluminum foil coils, according to the coil diameter of the aluminum foil coils and the position of the aluminum foil coils relative to the aluminum foil coil lifting mechanism, control the two sets of inclined plane support blocks to move closer to or away from each other, and can adjust the aluminum foil coils placed on the two sets of inclined plane support blocks at different heights, so that the aluminum foil coils can be accurately loaded onto the aluminum foil coil lifting mechanism, or the aluminum foil coils after the annealing treatment can be unloaded from the aluminum foil coil lifting mechanism. At the same time, it can also be effectively applicable to aluminum foil coils of different sizes, having a better scope of application. Brief Description of the Drawings

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the solutions of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0029] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 to 10 , and will detail this application in combination with the embodiments. Embodiment 1

[0030] Embodiment 1 discloses an energy-saving annealing treatment device for light foil processing. Refer to the attached Figures 1 - 3, including a bottom plate 1. Two gantry frames 2 are symmetrically arranged at the left and right ends of the bottom plate 1. Hydraulic cylinders 3 are arranged at the upper ends of the two gantry frames 2. Then, a lifting plate 4 is arranged between the two gantry frames 2, and the lower ends of the two hydraulic cylinders 3 are respectively connected to the two ends of the lifting plate 4. In addition, in order to ensure that the lifting plate 4 can move up and down stably, vertical grooves are opened on the front and back sides of each gantry frame 2. Vertical sliding rods 5 are arranged in the vertical grooves. Then, sliding hole blocks 6 that extend into the vertical grooves and interact with the vertical sliding rods 5 are arranged on the lifting plate 4.

[0031] Refer to the attached Figure 3 , attached Figure 4 and attached Figure 6 , three to five stepped round openings 401 are arranged in a row on the lifting plate 4, and the stepped round openings 401 are designed with a larger upper part and a smaller lower part. An annealing furnace cover 7 is concentrically arranged on the upper surface of the lifting plate 4 outside the stepped round openings 401. The annealing furnace cover 7 is cylindrical, its lower end is communicated with the stepped round openings 401, and its annular wall is composed of an inner heat insulation layer 701 and an outer plate surface layer 702. A vertically upward guiding cylinder 8 is arranged at the center of the top of the annealing furnace cover 7. A number of heat sources 9 are circumferentially and uniformly arranged on the inner wall of the annealing furnace cover 7. Specifically, the heat sources 9 can be selected from resistance heating rods or resistance heating wires, and their length directions are arranged parallel to the central axis of the annealing furnace cover 7.

[0032] A guiding rod 10 that vertically extends downward into the annealing furnace cover 7 is arranged in the guiding cylinder 703. A sealing round plate 11 that is adapted to the stepped round openings 401 is connected to the lower end of the guiding rod 10, and the sealing round plate 11 is also designed in a stepped shape, so that the sealing round plate 11 can be pressed and sealed in the stepped round openings 401 under its own gravity, thereby avoiding the outflow of heat in the annealing furnace cover 7.

[0033] Refer to the attached Figure 1 , attached Figure 2 and attached Figure 5 , a rotating cylinder 12 is rotatably arranged between the two gantry frames 2 directly below the lifting plate 4. Rotating shafts 13 are arranged at the centers of the two ends of the rotating cylinder 12. A side plate 14 connected to the rotating shaft 13 is arranged in one of the gantry frames 2, and a power device 15 for driving the rotating cylinder 12 to rotate is arranged outside the side plate 14. Specifically, the power device 15 is composed of a motor and a worm and worm gear speed reducer, so that it can not only make the rotating cylinder 12 rotate at a set angle, but also ensure the stability of the rotating cylinder 12 after rotation by using the self-locking function of the worm and worm gear. A support plate 16 is arranged in the other gantry frame 2, and a bearing seat 17 connected to the other rotating shaft 13 is arranged on the support plate 16, so that the rotating cylinder 12 can rotate stably under the action of the power device 15 and lock the state after rotation adjustment.

[0034] On the outer side surface of the rotating cylinder 12, at least two rows of aluminum foil roll lifting mechanisms 18 are evenly arranged. In this figure, a total of four groups of aluminum foil roll lifting mechanisms 18 are circumferentially arranged, and each aluminum foil roll lifting mechanism 18 is aligned with the stepped circular opening 401. Specifically, the aluminum foil roll lifting mechanism 18 includes a heat insulation end plate 181 fixedly connected to the rotating cylinder 12. The diameter of the heat insulation end plate 181 is equal to or slightly smaller than the lower diameter of the stepped circular opening 401, so that the heat insulation end plate 181 can seal the stepped circular opening 401 when it extends into the stepped circular opening 401. Finally, a central rod 182 that can pass through the center of the aluminum foil roll 100 is fixedly arranged at the center of the heat insulation end plate 181, thereby positioning the aluminum foil roll.

[0035] Reference appendix Figure 1 and appendix Figure 2 Refer to the attached drawings, at the front and rear ends of the bottom plate 1, a loading mechanism 19 and an unloading mechanism 20 are respectively arranged. The loading mechanism 19 and the unloading mechanism 20 have the same structure and are symmetrically arranged front and back with the center connection line of the two gantry frames 2 as the axis of symmetry. In addition, slide rails 21 are arranged at the front and rear ends of the upper surface of the bottom plate 1, and the loading mechanism 19 and the unloading mechanism 20 are slidably arranged on the corresponding slide rails 21. Then, through corresponding pushing or traction mechanisms (not shown in the figure), the loading mechanism 19 and the unloading mechanism 20 can move close to or away from the rotating cylinder 12, thereby completing loading and unloading.

[0036] During the operation of the energy-saving annealing treatment device for light foil processing disclosed in this Embodiment 1, the loading mechanism 19 pushes multiple aluminum foil rolls 100 onto the aluminum foil roll lifting mechanism 18, so that the center of the aluminum foil roll 100 is penetrated by the central rod 182.

[0037] Then, the power device 15 is started to rotate the rotating cylinder 12 by a certain angle, so as to rotate and adjust the aluminum foil roll 100 on the aluminum foil roll lifting mechanism 18 to be vertically upward and aligned with the stepped circular opening 401 up and down. Then, the two hydraulic cylinders 3 push the lifting plate 4 downward, so that the central rod 182 acts on the center of the lower surface of the sealing circular plate 11 and pushes it upward. At this time, the stepped circular opening 401 is opened, and the aluminum foil roll 100 can extend into the corresponding annealing furnace hood 7 through the stepped circular opening 401 until the heat insulation end plate 181 seals the lower end of the stepped circular opening 401, so that the annealing furnace hood 7 is completely sealed. After the aluminum foil roll 100 is located in the annealing furnace hood 7, the aluminum foil roll 100 is heated and annealed by the heat emitted from the heat source 9.

[0038] After annealing is completed, the hydraulic cylinder 3 runs in the reverse direction to lift the lifting plate 4 upward, so that the aluminum foil roll 100 is drawn out from the stepped circular opening 401. Since the diameter of the aluminum foil roll 100 is slightly smaller than the diameter of the stepped circular opening 401, during the process of drawing out the aluminum foil roll 100, the annular gap between the two is small. Coupled with the heat gathering at the upper end of the inner cavity of the annealing furnace hood 7, only a small amount of heat flows out through the annular gap. When the aluminum foil roll 100 is completely drawn out from the stepped circular opening 401, the sealing circular plate 11 will quickly seal the stepped circular opening 401 under the action of its own gravity and the guiding of the guiding rod 10, which can avoid the heat flow rate in the annealing furnace hood 7.

[0039] Finally, start the power device 15 again to rotate and switch the aluminum foil roll lifting mechanism 18 carrying the next group of aluminum foil rolls 10 to the uppermost position to be aligned with the annealing furnace hood 7 up and down, and repeat the above steps to push the aluminum foil roll 10 into the annealing furnace hood 7, while the annealed aluminum foil roll can be removed through the blanking mechanism 20. Embodiment 2

[0040] Embodiment 2 discloses an energy-saving annealing treatment device which is optimized and improved based on the technical solution in Embodiment 1, and the same parts as those in Embodiment 1 will not be described again.

[0041] Refer to Att Figure 5 、Att Figure 7 and Att Figure 8 Referring to Att

[0042] In the present embodiment 2, a transmission cavity 121 is opened inside the rotating cylinder 12. The rotating shaft 13 connected to the bearing seat 17 is redesigned as a hollow shaft 122. A rotating motor 123 is fixedly installed at the outer end of the hollow shaft 122. A rotating rod 124 is connected to the motor shaft of the rotating motor 123, passes through the hollow shaft 122 and extends into the transmission cavity 121. A driving bevel gear 125 aligned with each aluminum foil roll lifting mechanism 18 is arranged on the rotating rod 124.

[0043] In addition, the central rod 182 in this Embodiment 2 is redesigned to a structure similar to an expansion shaft, which includes an outer shaft cylinder 185. A plurality of strip-shaped openings designed along the axial direction are circumferentially and evenly formed on the outer circumferential surface of the outer shaft cylinder 185. A tensioning strip 186 extending into the interior of the outer shaft cylinder 185 is provided in each strip-shaped opening, and a spring ring 187 is sleeved between the plurality of tensioning strips 186 to provide an elastic force for contracting towards the center. An inclined surface pressing opening is formed at the inner end of the tensioning strip 186. A pressing rod 188 with its top end extending is concentrically arranged in the outer shaft cylinder 185, and a spring 189 is connected between the bottom of the pressing rod 188 and the heat insulation end plate 181. Finally, a pressing inclined surface block 190 matching the inclined surface pressing openings on all the tensioning strips 186 is arranged on the pressing rod 188.

[0044] During the operation of the energy-saving annealing treatment device disclosed in this Embodiment 2, the aluminum foil roll 100 is loaded into the aluminum foil roll supporting mechanism 18 by the feeding mechanism 19, and the outer shaft cylinder 185 penetrates through the center of the aluminum foil roll 100. Then, the aluminum foil roll supporting mechanism 18 loaded with the aluminum foil roll 100 is rotated and adjusted vertically upward by the power device 15 so that it is aligned with each stepped circular opening 401 up and down.

[0045] Then, by pushing the lifting plate 4 downward, during the downward pushing process of the lifting plate 4, the pressing rod 188 extending out of the top end of the outer shaft cylinder 185 acts on the center of the lower surface of the sealing circular plate 11 and pushes it upward. At this time, due to the certain gravity of the sealing circular plate 11, the pressing rod 188 will first move downward along the outer shaft cylinder 185 and the spring 189 will be compressed. Then, the pressing inclined surface block 190 acts on the inclined surface pressing openings on the tensioning strips 186, causing all the tensioning strips 186 to expand outward against the acting force of the spring ring 187, so that the aluminum foil roll 100 is tightened and fixed by the tensioning strips 186. After being tightened and fixed, the aluminum foil roll 100 continues to be extended into the annealing furnace hood 7. And because the top of the guiding rod 10 is limited by the guiding cylinder 703, the pressing rod 188 will be further compressed into the outer shaft cylinder 185 during the process of lifting the sealing circular plate 11, so as to further tighten and fix the aluminum foil roll 100, and the stepped circular opening 401 is sealed by the heat insulation end plate 181.

[0046] During the subsequent heating process of the aluminum foil roll 100 by the heat source 9, the rotating motor 123 can be started, and through the meshing transmission between the bevel gears, the aluminum foil roll supporting mechanism 18 and the aluminum foil roll 100 carried thereon slowly rotate in the annealing furnace hood 7, so that the aluminum foil roll 100 can be evenly heated by the heat emitted by the heat source 9, thus realizing uniform annealing treatment. Embodiment 3

[0047] Embodiment 3 discloses an energy-saving annealing treatment device which is optimized and improved based on the technical solution in Embodiment 1, and the same parts as those in Embodiment 1 will not be described again.

[0048] In this Embodiment 3, the feeding mechanism 19 and the discharging mechanism 20 are mainly designed so that aluminum foil rolls 100 with different coil diameters can be accurately loaded onto the aluminum foil roll supporting mechanism 18, or the aluminum foil rolls 100 after the annealing treatment can be unloaded from the aluminum foil roll supporting mechanism.

[0049] Refer to the attached Figure 9 and the attached Figure 10 As shown in the figure, both the feeding mechanism 19 and the discharging mechanism 20 include a moving seat 191. A slide rail bar 192 that interacts with the slide rail 21 is provided on the lower surface of the moving seat 19. A cavity is formed inside the moving seat 191, and a transmission rod 193 is rotatably arranged in the cavity. One end of the transmission rod 193 is in transmission connection with an adjustment motor 194 through gear meshing. A pair of reverse threads 195 aligned with each aluminum foil roll supporting mechanism 18 are formed on the transmission rod 193. The pair of reverse threads 195 are divided into two sections, and the spiral directions are opposite.

[0050] On the upper surface of the moving seat 191, an inclined plane support adjustment component aligned with each aluminum foil roll supporting mechanism 18 is provided. The inclined plane support adjustment component includes two groups of inclined plane support blocks 196 that are mirror-symmetrical about the left and right and are arranged in a staggered manner. A linear opening 197 communicating with the internal cavity of the moving seat 191 is formed on the upper surface of the moving seat 191. Then, a threaded hole block 198 that extends into the internal cavity of the moving seat 191 through the linear opening 197 is fixedly connected to the lower surface of each inclined plane support block 196, and the threaded hole blocks 198 connected to the two groups of inclined plane support blocks 196 are respectively matched with the two sections of the corresponding pair of reverse threads 195.

[0051] In this Embodiment 3, through the structural design of the above feeding mechanism 19 and discharging mechanism 20, when the aluminum foil roll 100 is placed on the inclined plane support adjustment component, the transmission rod 193 can be rotated by the adjustment motor 194, and then through the transmission action between the pair of reverse threads 195 and the threaded hole blocks 198, the two groups of inclined plane support blocks 196 can move closer to or away from each other.
