Description

Technical Field

[0001] The invention relates to the technical field of aluminum material production equipment, and in particular to an efficient and uniform aluminum coil annealing device. Background Art

[0002] Aluminum and aluminum alloys are the most widely used nonferrous metal structural materials in industry, and have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, chemical industry, and daily necessities. In the production and processing of aluminum materials, annealing is an indispensable process, which can eliminate the residual stress in the aluminum strip and improve the tensile strength and mechanical properties of the aluminum strip.

[0003] In the prior art, the aluminum coil is usually placed in an annealing furnace for annealing. However, since the external heat in the annealing furnace is gradually heated from the outer surface of the aluminum coil to the inside, and finally the entire aluminum coil is heated, the heating efficiency of the annealing furnace is low, the heat energy loss is large, and the outer and inner parts of the aluminum coil are heated unevenly, which affects the annealing effect of the aluminum coil. Summary of the invention

[0004] The purpose of the present invention is to provide an efficient and uniform aluminum coil annealing device, in which the aluminum coil is repeatedly loosened and wound in an annealing furnace, and the aluminum strip on the aluminum coil is annealed in a single layer, which not only improves the uniformity of the aluminum coil annealing, but also improves the annealing efficiency of the aluminum coil, while ensuring that the annealing time of the aluminum strip is sufficient, and effectively ensures the annealing quality of the aluminum strip.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] An efficient and uniform aluminum coil annealing device comprises an annealing furnace and a material transport trolley, wherein a heating chamber is arranged in the annealing furnace, and a feeding guide rail matched with the material transport trolley is arranged in the heating chamber; a feeding port located at one end of the feeding guide rail and connected with the heating chamber is arranged on the side wall of the annealing furnace, and the feeding port is matched with the material transport trolley and is provided with a sealing baffle door;

[0007] The material transport trolley is provided with a plurality of unloading units and auxiliary roll units in an array along its length direction, the unloading units and auxiliary roll units are arranged at intervals and cooperate with each other, and the heating chamber is provided with a driving mechanism located on one side of the feed guide rail and cooperates with the plurality of unloading units and auxiliary roll units;

[0008] The unloading unit comprises an unloading cylinder whose axis is arranged along the width direction of the material transport trolley, an aluminum coil coaxially wound outside the unloading cylinder, a support seat located below the aluminum coil is provided on the material transport trolley, and an arc-shaped support groove matched with the outer wall of the aluminum coil is provided on the upper end surface of the support seat;

[0009] The auxiliary roll unit comprises an auxiliary roll whose axis is parallel to the axis of the unwinding drum, and the material transport trolley is provided with an auxiliary roll frame located at one end of the auxiliary roll away from the driving mechanism, the auxiliary roll frame is vertically arranged and one end of the auxiliary roll is positioned and rotatably mounted on the side wall of the auxiliary roll frame;

[0010] The driving mechanism comprises a driving frame arranged on one side of the feeding guide rail along the length direction of the feeding guide rail, and the driving frame is provided with a plurality of unwinding driving shafts and auxiliary roll driving shafts arranged along the width direction thereof in an array along the length direction thereof, and the unwinding driving shaft and the auxiliary roll driving shaft are positioned and rotatably mounted on the driving frame at one end close to the driving frame;

[0011] The drive frame is slidably installed in the annealing furnace along the width direction of the feed guide rail, and the unloading drive shaft and the auxiliary roll drive shaft are respectively engaged with the corresponding unloading cylinder and the auxiliary roll cylinder; the unloading drive shaft and the auxiliary roll drive shaft are each provided with a coaxial heat conduction cavity, and the heat conduction cavity is provided with a heating rod arranged along its length direction.

[0012] By adopting the above technical solution, the aluminum coils that need to be annealed are placed in the arc-shaped support groove of the support seat on the material transport trolley in sequence, the axis of the discharge barrel is parallel to the axis of the arc-shaped support groove, and the outer wall of the aluminum coil is in contact with the inner wall of the arc-shaped support groove. The end of the aluminum strip on the aluminum coil is pulled to the corresponding auxiliary reel and fixed on the auxiliary reel to ensure that the end of the aluminum strip does not loosen and tumble. After opening the sealing baffle door, the material transport trolley is sent from the feed port along the feed guide rail into the heating chamber of the annealing furnace, and then the drive frame is moved as a whole toward the direction close to the material transport trolley, and a number of discharge drive shafts and auxiliary roll drive shafts are inserted into the corresponding discharge barrel and auxiliary reel. After the operation is completed, the sealing baffle door is closed to ensure the sealing of the heating chamber.

[0013] The heating rods in the heating chamber and the heat transfer chamber work and heat, the auxiliary roll drive shaft drives the auxiliary roll to rotate and rewind the aluminum strip on the aluminum roll, and the unwinding drive shaft drives the unwinding roll to rotate and unwind the aluminum strip on the aluminum roll, that is, the aluminum roll on the unwinding roll is rewound onto the auxiliary roll. When the remaining aluminum roll on the unwinding roll reaches a certain length, the auxiliary roll drive shaft and the unwinding drive shaft reverse respectively, the unwinding drive shaft rotates to rewind the aluminum strip, and the auxiliary roll drive shaft rotates to unwind the aluminum strip, that is, the aluminum roll on the auxiliary roll is rewound onto the unwinding roll. In this way, several aluminum rolls are repeatedly unwound and wound in the annealing furnace. The aluminum strip is annealed in a single layer in the heating chamber during the unwinding and winding process, and the heating rods in the heat transfer chamber anneal the ends of the aluminum strip that are always wound on the auxiliary roll and the unwinding roll from the inside to the outside, which not only improves the uniformity of the annealing of the aluminum roll, but also improves the annealing efficiency of the aluminum roll, while ensuring that the annealing time of the aluminum strip is sufficient, effectively ensuring the annealing quality of the aluminum strip.

[0014] Furthermore, the outer wall of the auxiliary reel is provided with a clamping opening arranged along its length direction, and the depth of the clamping opening is less than the wall thickness of the auxiliary reel; the clamping opening is symmetrically provided with clamping plates on both sides along its length direction, and the two clamping plates are arranged along the length direction of the clamping opening, and slide closer to or away from each other along the width direction of the clamping opening; limit blocks are respectively provided at both ends of the clamping opening, and the two limit blocks are slidably installed in the clamping opening along the length direction of the clamping opening.

[0015] By adopting the above technical scheme, a clamping port is set outside the auxiliary reel, and the end of the aluminum strip pulled from the aluminum coil of the unwinding drum is inserted into the clamping port, and the end of the aluminum strip is clamped and fixed by two clamping plates, so that the aluminum strip can be rolled up when the auxiliary reel is driven by the auxiliary reel driving shaft to rotate, and the end of the aluminum strip is prevented from being separated from the auxiliary reel, which affects the repeated winding and loosening of the aluminum strip. Among them, limit blocks are set at both ends of the clamping port, and the end of the aluminum strip is limited from both sides by the limit blocks, so that the end of the aluminum strip is prevented from being offset when it is clamped between the two clamping plates, which affects the neat winding of the aluminum strip by the auxiliary reel. The two clamping plates are relatively slidable, and the two limit blocks are relatively slidable, so that aluminum strips of different thicknesses and widths can be clamped and fixed, thereby improving the scope of application of the present invention. In addition, the depth of the clamping port is less than the wall thickness of the auxiliary reel, so that the end of the aluminum strip is prevented from being inserted into the inner cavity of the auxiliary reel, which affects the insertion and clamping of the auxiliary reel of the auxiliary reel driving shaft, and ensures that the auxiliary reel driving shaft can smoothly drive the auxiliary reel to rotate, rewind or loosen the aluminum strip.

[0016] Furthermore, the two side walls of the clamping port along its length direction are respectively provided with mounting grooves that cooperate with corresponding clamping plates, and the sides of the two clamping plates that are away from each other are respectively installed in the corresponding mounting grooves; the sides of the two clamping plates that are away from each other are provided with a plurality of guide rods in an array along their length direction, and the axes of the guide rods are arranged horizontally perpendicular to the clamping plates; the side walls of the two mounting grooves that are away from each other are respectively provided with a plurality of guide holes that cooperate with corresponding guide rods, and one end of the guide rod that is away from the clamping plate is slidably installed in the corresponding guide hole; a clamping spring arranged along the axial direction of the guide rod is provided between the ends of the guide rod and the guide hole that are close to each other, and when the clamping spring is in a normal state, the ends of the two clamping plates that are close to each other are located in the clamping port.

[0017] By adopting the above technical solution, the clamping plate is installed in the installation groove, and the guide rod is slidably installed in the guide hole, so that the two clamping plates are slidably installed in the clamping port, and the sliding stability of the two clamping plates is ensured. Under the tightening action of the tightening spring, the side of the two clamping plates close to each other always tightly clamps the ends of the aluminum strips of different thicknesses from both sides, ensuring the clamping and fixing effect of the ends of the aluminum strips, and ensuring the stability of the auxiliary reel winding or releasing the aluminum strip. It has a simple structure, is easy to operate, has a wide range of applications, and has obvious effects.

[0018] Furthermore, the ends of the two limit blocks that are away from each other are respectively provided with limit rods arranged along the length direction of the clamping port, and the two ends of the clamping port are provided with limit holes that cooperate with the limit rods; the two ends of each limit block are provided with sliding holes arranged along the width direction of the clamping port, and a sliding rod is slidably installed in the sliding hole, and an adjusting part is connected between the ends of the two sliding rods on the limit block that are away from each other and the clamping plate.

[0019] By adopting the above technical solution, the limit rod is slidably installed in the limit hole, so that the limit block can be slidably installed in the clamping port, and the stability of the sliding of the two limit blocks is ensured. The sliding rod is slidably installed in the sliding hole, and an adjustment member is connected between the sliding rod and the clamping plate. The adjustment member is used to drive the limit block to slide along the axis of the limit hole to adjust the distance between the two limit blocks, so that it can limit aluminum strips of different widths from both sides to ensure the stability of the aluminum strip winding or loosening. The sliding rod is slidably installed in the sliding hole to avoid interference between the sliding of the limit block along the length direction of the clamping port and the sliding of the clamping plate along the width direction of the clamping port, ensuring that both the clamping plate and the limit block can be smoothly adjusted and work smoothly.

[0020] Furthermore, the adjusting member includes an adjusting rod arranged along the length direction of the clamping port, and the end of the adjusting rod away from the clamping plate is connected to the corresponding sliding rod to form an L-shape, and adjustment holes cooperating with the corresponding adjusting rod are provided at both ends of the clamping plate; an elastic snap is provided on the side wall of the end of the adjusting rod away from the sliding rod, and a plurality of adjusting card holes connected to the adjusting holes are arranged in an array along the length direction of the side wall of the clamping plate close to the opening of the clamping port, and the adjusting card holes cooperate with the elastic snaps.

[0021] By adopting the above technical solution, the elastic snap button is clamped in the adjustment hole at different positions, so as to adjust the distance between the end of the adjustment rod connected to the sliding rod and the end of the clamping plate. When the adjustment rod is moved and fixed, the sliding rod can be used to drive the limit block to slide in the clamping port, that is, the distance between the two limit blocks can be adjusted, so that it can limit the two sides of aluminum strips of different widths. Among them, the adjustment hole is set on the side wall of the clamping port close to the opening of the clamping port, which is convenient for pressing the elastic snap button and avoids the elastic snap button from contacting the surface of the end of the aluminum strip, so as to avoid the elastic snap button from crushing the surface of the aluminum strip. It has a simple structure, is easy to operate and has obvious effects.

[0022] Furthermore, the auxiliary drum inner wall circular array is provided with a plurality of heat-conducting holes arranged radially along its axis, one end of the heat-conducting hole is connected to the auxiliary drum inner cavity, and the other end passes through the auxiliary drum outer wall, and the heat-conducting holes are arranged in a plurality of groups in an array along the axial direction of the auxiliary drum.

[0023] By adopting the above technical scheme, since a clamping port is provided, in order to ensure that there is sufficient space in the clamping port to facilitate the installation of components such as clamps and limit blocks, and the end of the aluminum strip must be able to be clamped at a certain length to ensure the stability of the fixation of the end of the aluminum strip, the auxiliary reel needs to have a certain wall thickness, and a large wall thickness affects the heat transmission of the heating rod in the auxiliary reel drive shaft. Therefore, a number of heat conduction holes that pass through the wall thickness of the auxiliary reel are provided to achieve heat transfer, ensuring that the heat of the heat conduction cavity on the auxiliary reel drive shaft can be quickly and evenly transferred to the aluminum strip wound on the outer wall of the auxiliary reel, thereby achieving uniform annealing of the end of the aluminum strip that is always wrapped around the outer wall of the auxiliary reel.

[0024] Furthermore, several of the unloading drive shafts are connected to the unloading drive mechanism, and several of the auxiliary roll drive shafts are connected to the auxiliary roll drive mechanism. The unloading drive mechanism and the auxiliary roll drive mechanism are respectively connected to a unloading meter counter and an auxiliary roll meter counter. The unloading meter counter is connected to the auxiliary roll drive mechanism for communication feedback control, and the auxiliary roll meter counter is connected to the unloading drive mechanism for communication feedback control. The side wall of the drive frame is provided with a thermal insulation protection cover arranged along its length direction, and the unloading drive mechanism and the auxiliary roll drive mechanism are both located in the thermal insulation protection cover.

[0025] By adopting the above technical solution, the unloading drive mechanism drives several unloading drive shafts to work synchronously, and drives several unloading drums to rotate and reel or unwind the aluminum strip. The auxiliary roll drive mechanism drives several auxiliary roll drive shafts to work synchronously, and drives several auxiliary rolls to rotate and unwind or unwind the aluminum strip. In this way, the reeling or unwinding of several aluminum rolls is carried out simultaneously, avoiding large differences in annealing effects of several aluminum rolls within the same annealing time, which affects the annealing quality of the aluminum roll. Among them, the auxiliary roll meter meter calculates the length of the aluminum strip wound on the auxiliary roll, and the unloading meter meter calculates the unwinding length of the aluminum roll on the unloading drum, so as to judge the remaining amount of the aluminum roll on the unloading drum. When the remaining amount reaches the set value, the unloading meter meter communication feedback controls the auxiliary roll drive mechanism to stop driving the auxiliary roll to continue to rotate and rewind, and the auxiliary roll meter meter communication feedback controls the unloading drive mechanism to drive the unloading drum to rotate in the opposite direction to rewind the aluminum strip. Vice versa, this is repeated, so that the unloading drive mechanism and the auxiliary roll drive mechanism work alternately, thereby realizing the repeated reeling and unwinding of the aluminum strip. In addition, a thermal insulation protection cover is provided to provide thermal insulation protection for the unloading drive mechanism and the auxiliary roll drive mechanism, so as to prevent the high temperature in the heating chamber from having too great an impact on the service life of the unloading drive mechanism and the auxiliary roll drive mechanism.

[0026] Furthermore, the unloading drive mechanism includes a unloading gear connected to one end of the unloading drive shaft close to the driving frame, several of the unloading gears are coaxially arranged with the corresponding unloading drive shaft, and a unloading chain meshing with them is connected therebetween, and one of the unloading gears is connected to a unloading motor that drives it to rotate; the auxiliary roll driving mechanism includes several linkage shafts located below and parallel to the corresponding auxiliary roll driving shaft, one end of the linkage shaft is positioned and rotatably mounted on the driving frame; each group of corresponding auxiliary roll driving shafts and linkage shafts are provided with mutually matching transmission wheels, and a transmission belt is connected between the transmission wheels; a linkage gear located on one side of the transmission wheel and coaxial with it is installed on the linkage shaft, and several of the linkage gears are connected with linkage chains meshing with them, and one of the linkage gears is connected to the auxiliary roll motor that drives it to rotate.

[0027] By adopting the above technical solution, the unloading motor drives the corresponding unloading gear to rotate, and under the meshing action of the unloading gear and the unloading chain, drives other unloading gears to rotate synchronously, thereby realizing driving several unloading drive shafts to synchronously drive the corresponding unloading drum to rotate. The auxiliary roll motor drives the corresponding linkage gear to rotate, and under the meshing action of the linkage gear and the linkage chain, drives other linkage gears to rotate synchronously, thereby realizing driving several linkage shafts to rotate synchronously, and under the transmission action of the transmission wheel and the transmission belt, the linkage shaft drives several auxiliary roll drive shafts to rotate synchronously, that is, realizes that several auxiliary roll drive shafts synchronously drive the auxiliary reel to rotate. The above-mentioned unloading drive mechanism and auxiliary roll drive mechanism have a simple structure, and use gear chain transmission and belt transmission to realize the synchronous drive of several unloading drive shafts and several auxiliary roll drive shafts, which is convenient to operate and has a stable transmission effect, ensuring the stability of winding and releasing the aluminum coil.

[0028] Furthermore, a rectangular array at the bottom of the support seat is provided with a plurality of vertically arranged support rods, and the material transport trolley is provided with a plurality of vertically arranged guide cylinders with openings at the upper ends, and the lower ends of the support rods are vertically slidably installed in the corresponding guide cylinders; a vertically arranged tension spring is provided between the lower end of the support rod and the inner bottom wall of the guide cylinder, and in the initial state, under the action of the tension spring, the axis of the discharge cylinder and the axis of the discharge drive shaft are located in the same horizontal plane.

[0029] By adopting the above technical solution, the support rod is slidably installed in the guide cylinder, so that the support seat can be vertically slidably installed on the material transport trolley. The diameters of aluminum coils of different weights are different. The heavier aluminum coils are heavier, which will compress the tension spring to make the support plate slide vertically downward, that is, its axis line will drop; the relatively light aluminum coils have insufficient gravity, and the tension spring will make the support plate slide vertically upward, that is, the axis line of the aluminum coil will rise. In the initial state, under the action of the tension spring, the axis of the discharge barrel and the axis of the discharge drive shaft are located in the same horizontal plane, so that when aluminum coils of various specifications are annealed, the discharge drive shaft can be accurately inserted into the discharge barrel and clamped with it, without adjusting the height of the discharge drive shaft, simplifying the structure of the drive mechanism in the annealing furnace. In addition, as the aluminum coil on the unloading drum is released, the outer diameter and weight of the aluminum coil gradually decrease, or as the aluminum coil on the unloading drum is wound, the weight of the aluminum coil gradually increases. Under the action of the tension spring, the support seat is always in contact with the outer wall of the aluminum coil to provide support for the aluminum coil, preventing the aluminum coil from hanging in the air on the unloading drive shaft, reducing the load on the unloading drive shaft, and increasing the life of the unloading drive shaft.

[0030] Furthermore, anti-deflection shafts with axes parallel to the axis of the discharge barrel are positioned and rotatably installed at both ends of the support seat, and an anti-deflection clamping plate is provided at the end of the anti-deflection shaft away from the support seat, and the upper end of the anti-deflection clamping plate is located below the discharge barrel, and the lower end of the anti-deflection clamping plate is limitedly slidably connected to the anti-deflection shaft, and its sliding direction is set along the length direction of the anti-deflection shaft; a tensioning spring arranged along the length direction of the anti-deflection shaft is provided between the side where the anti-deflection clamping plate and the support seat are close to each other, and the tensioning spring is sleeved outside the anti-deflection shaft.

[0031] By adopting the above technical scheme, the aluminum strip wound on the discharge drum is limited by the anti-deflection card plate, and the aluminum strip after annealing is wound on the discharge drum, so as to avoid the deviation of the aluminum strip winding and affect the operation of the next process. The anti-deflection card plate is slidably installed on the anti-deflection shaft, so that the anti-deflection card plate can limit the deflection of aluminum strips of different widths, and the anti-deflection card plate is always in contact with the side wall of the aluminum coil by the tension spring, effectively ensuring the anti-deflection effect of the aluminum strip. Among them, a positioning and rotating anti-deflection shaft is set, and when the aluminum coil is placed on the support seat or the aluminum coil is removed from the support seat, the anti-deflection shaft can be rotated to rotate the anti-deflection card plate to vertically downward, so as to avoid the anti-deflection card plate affecting the placement or material removal of the aluminum coil. The tension spring is sleeved outside the anti-deflection shaft, and the anti-deflection shaft plays a certain supporting role on the tension spring, avoiding the deformation of the tension spring along its radial direction after long-term work, and effectively ensuring the use effect and service life of the tension spring.

[0032] In summary, the present invention has the following beneficial effects:

[0033] 1. The present invention arranges a plurality of unwinding units and auxiliary coiling units that cooperate with each other on a material transport trolley, wherein the unwinding unit comprises an unwinding drum and an aluminum coil, and the auxiliary coiling unit comprises an auxiliary coiling drum. A driving mechanism that cooperates with the unwinding unit and the auxiliary coiling unit is arranged in an annealing furnace, and the driving mechanism comprises an unwinding driving shaft that cooperates with the unwinding drum and an auxiliary coiling driving shaft that cooperates with the auxiliary coiling drum. A heat conduction cavity and a heating rod are arranged in the unwinding driving shaft and the auxiliary coiling driving shaft. A plurality of aluminum coils are repeatedly unwound and wound in the annealing furnace. The aluminum strip is subjected to single-layer annealing in the heating cavity during the unwinding and winding process, and the heating rod in the heat conduction cavity anneals the ends of the aluminum strip that are always wound on the auxiliary coiling drum and the unwinding drum from the inside to the outside, thereby not only improving the uniformity of the annealing of the aluminum coil, but also improving the annealing efficiency of the aluminum coil, while ensuring that the annealing time of the aluminum strip is sufficient, and effectively ensuring the annealing quality of the aluminum strip.

[0034] 2. The present invention provides a clamping opening on the auxiliary reel, and provides a clamping plate and a limiting block in the clamping opening, so that the end of the aluminum strip pulled out of the aluminum coil is inserted into the clamping opening, and the end of the aluminum strip is clamped and fixed by two clamping plates, and the aluminum strip is limited from both sides by limiting blocks, so that the aluminum strip can be rolled up when the auxiliary reel is driven by the auxiliary reel driving shaft to rotate, and the end of the aluminum strip can be prevented from being separated and offset from the auxiliary reel, which affects the repeated winding and loosening of the aluminum strip; and the two clamping plates slide relatively along the width direction of the clamping opening, and the two limiting blocks slide relatively along the length direction of the clamping opening, so that aluminum strips of different thicknesses and widths can be clamped and limited, effectively improving the scope of application of the present invention;

[0035] 3. The present invention vertically slides and installs the support base on the material transport trolley. During the process of winding and unwinding the aluminum coil, the support base always supports the aluminum coil to prevent the aluminum coil from hanging in the air on the material discharge drive shaft, thereby reducing the load on the material discharge drive shaft and increasing the life of the material discharge drive shaft. In addition, anti-deflection clamping plates are provided at both ends of the support base to limit the aluminum coil, so as to prevent the deviation of the aluminum strip during winding and affect the operation of the next process, and the anti-deflection clamping plates can limit and prevent the deviation of aluminum strips of different widths under the action of the tensioning spring, thereby effectively ensuring the anti-deflection effect and improving the scope of application of the present invention.

The unloading driving shaft 72 and the auxiliary roll driving shaft 73 are positioned and rotatably installed on the driving frame 71 at one end close to the driving frame 71. The driving frame 71 is slidably installed in the annealing furnace 1 along the width direction of the feed guide rail 12.

When the remaining length of the aluminum coil 32 on the unwinding drum 31 reaches a certain length, the auxiliary coil drive shaft 73 and the unwinding drive shaft 72 reverse respectively, the unwinding drive shaft 72 rotates to rewind the aluminum strip, and the auxiliary coil drive shaft 73 rotates to loosen the aluminum strip, so as to rewind the aluminum coil 32 on the auxiliary coil 42 onto the unwinding drum 31.

[0049] like Figures 1 to 3 As shown, in this way, a plurality of aluminum coils 32 are repeatedly released and wound in the annealing furnace 1. The aluminum strip is subjected to single-layer annealing in the heating chamber 11 during the release and winding process, and the heating rod 75 in the heat conduction chamber 74 anneals the ends of the aluminum strip that are always wound around the auxiliary reel 42 and the unwinding reel 31 from the inside to the outside, which not only improves the uniformity of the annealing of the aluminum coil 32, but also improves the annealing efficiency of the aluminum coil 32, while ensuring that the annealing time of the aluminum strip is sufficient, thereby effectively ensuring the annealing quality of the aluminum strip.

[0050] like Figure 3 As shown, in this embodiment, in order to realize the sliding of the driving frame 71 along its width direction, a driving rod 711 is provided along its sliding direction on the side of the driving frame 71 away from the feed guide rail 12, and the surface of the driving rod 711 is subjected to high temperature resistance treatment. A protective cover 713 is provided in the annealing furnace 1, and a driving cylinder 712 is provided in the protective cover 713 along the length direction of the driving rod 711. One end of the driving rod 711 away from the driving frame 71 extends into the protective cover and is connected to the piston rod end of the driving cylinder 712. In this way, the driving cylinder 712 is used to drive the driving frame 71 to slide, and the driving cylinder 712 is always located in the protective cover 713 as a whole, reducing the influence of high temperature on the service life of the driving cylinder 712.

[0051] like Figure 3 and Figure 4As shown, in order to realize driving a plurality of unloading drive shafts 72 and auxiliary roll drive shafts 73 to drive the corresponding unloading drum 31 and auxiliary roll drum 42 to rotate synchronously, a plurality of unloading drive shafts 72 are connected to the unloading drive mechanism 8, and a plurality of auxiliary roll drive shafts 73 are connected to the auxiliary roll drive mechanism 9. A heat-insulating protective cover 76 is provided on the side wall of the driving frame 71 along its length direction, and the unloading drive mechanism 8 and the auxiliary roll drive mechanism 9 are both located in the heat-insulating protective cover 76 to reduce the influence of the high temperature in the heating chamber 11 on the unloading drive mechanism 8 and the auxiliary roll drive mechanism 9.

[0052] like Figure 4 As shown, in this embodiment, the discharge drive mechanism 8 includes a discharge gear 81 connected to one end of the discharge drive shaft 72 close to the drive frame 71, and a plurality of discharge gears 81 are coaxially arranged with the corresponding discharge drive shaft 72, and a discharge chain 82 (only shown in a belt shape in the figure) meshing therewith is connected therebetween, and one of the discharge gears 81 is connected to a discharge motor 83 that drives it to rotate. The discharge motor 83 drives the corresponding discharge gear 81 to rotate, and under the meshing action of the discharge gear 81 and the discharge chain 82, it drives the other discharge gears 81 to rotate synchronously, thereby realizing driving a plurality of discharge drive shafts 72 to synchronously drive the corresponding discharge barrel 31 to rotate.

[0053] like Figure 4 As shown, in this embodiment, the auxiliary roll driving mechanism 9 includes a plurality of linkage shafts 91 located below and parallel to the corresponding auxiliary roll driving shafts 73, one end of the linkage shaft 91 is positioned and rotatably mounted on the driving frame 71, each group of corresponding auxiliary roll driving shafts 73 and linkage shafts 91 are provided with mutually matching transmission wheels 92, and a transmission belt 93 is connected between the transmission wheels 92. A linkage gear 94 located on one side of the transmission wheel 92 and coaxial with the transmission wheel 92 is installed on each linkage shaft 91, and a linkage chain 95 (only belt-shaped is shown in the figure) meshing with the plurality of linkage gears 94 is connected, and one of the linkage gears 94 is connected to an auxiliary roll motor 96 that drives it to rotate. The auxiliary roll motor 96 drives the corresponding linkage gear 94 to rotate, and under the meshing action of the linkage gear 94 and the linkage chain 95, it drives the other linkage gears 94 to rotate synchronously, thereby realizing driving the plurality of linkage shafts 91 to rotate synchronously. Under the driving action of the driving wheel 92 and the driving belt 93 , the linkage shaft 91 drives the plurality of auxiliary roll driving shafts 73 to rotate synchronously, that is, the plurality of auxiliary roll driving shafts 73 drives the auxiliary roll 42 to rotate synchronously.

[0054] like Figure 3 and Figure 4As shown, the unloading motor 83 is connected to the unloading meter 84, the auxiliary roll motor 96 is connected to the auxiliary roll meter 97, and the unloading meter 84 is connected to the auxiliary roll motor 96 for communication feedback control, and the auxiliary roll meter 97 is connected to the unloading motor 83 for communication feedback control. The auxiliary roll meter 97 calculates the length of the aluminum strip wound on the auxiliary reel 42, and the unloading meter 84 calculates the loose length of the aluminum coil 32 on the unloading drum 31, thereby judging the remaining amount of the aluminum coil 32 on the unloading drum 31. When the remaining amount of the aluminum coil 32 on the unloading drum 31 reaches the set value, the unloading meter 84 controls the auxiliary roll motor 96 to stop working, and the auxiliary roll meter 97 controls the unloading motor 83 to drive the unloading drum 31 to rotate in the opposite direction to wind up the aluminum strip. On the contrary, the auxiliary roll meter meter 97 calculates the length of the aluminum strip released by the auxiliary roll 42, and the unwinding meter meter 84 calculates the length of the aluminum strip wound by the unwinding roll 31, thereby judging the remaining amount of the aluminum strip on the auxiliary roll 42. When the remaining amount of the aluminum strip on the auxiliary roll 42 reaches the set value, the unwinding meter meter 84 controls the auxiliary roll motor 96 to start, and the auxiliary roll meter meter 97 controls the unwinding motor 83 to stop working. This is repeated to achieve the alternate operation of the unwinding drive shaft 72 and the auxiliary roll drive shaft 73, thereby achieving repeated winding and unwinding of the aluminum strip.

[0055] like Figure 2 and Figure 5 As shown, in this embodiment, in order to facilitate the fixing of the aluminum strip end of the aluminum coil 32 on the unwinding drum 31 on the outer wall of the auxiliary reel 42, a clamping opening 43 is provided on the outer wall of the auxiliary reel 42 along its length direction, and the depth of the clamping opening 43 is less than the wall thickness of the auxiliary reel 42, so as to prevent the aluminum strip end from being inserted into the inner cavity of the auxiliary reel 42 from the clamping opening 43, thereby affecting the clamping drive of the auxiliary reel drive shaft 73 and the auxiliary reel 42. Figure 5 and Figure 6 As shown, the clamping plates 5 located in the clamping opening 43 are symmetrically arranged on both sides of the clamping opening 43 along its length direction. The two clamping plates 5 are arranged along the length direction of the clamping opening 43 and slide towards or away from each other along the width direction of the clamping opening 43. Figure 2 and Figure 5 As shown, a clamping port 43 is provided outside the auxiliary reel 42, and the end of the aluminum strip pulled from the aluminum coil 32 of the unwinding drum 31 is inserted into the clamping port 43, and the end of the aluminum strip is clamped and fixed by two clamping plates 5, so that the aluminum strip can be rolled up when the auxiliary reel 42 is rotated by the auxiliary reel drive shaft 73, and the end of the aluminum strip is prevented from being separated from the auxiliary reel 42, which affects the repeated winding and unwinding of the aluminum strip. The two clamping plates 5 are relatively slidably arranged, and can clamp and fix aluminum strips of different thicknesses, thereby improving the scope of application of the present invention.

[0056] like Figure 5 and Figure 6As shown, the two side walls of the clamping opening 43 along the length direction thereof are respectively provided with mounting grooves 44 that match the corresponding clamping plates 5, and the two clamping plates 5 are respectively installed in the corresponding mounting grooves 44 on the sides away from each other. A plurality of guide rods 51 are arranged in an array along the length direction of the two clamping plates 5 on the sides away from each other, and the axes of the guide rods 51 are arranged horizontally perpendicular to the clamping plates 5; the two side walls of the mounting grooves 44 that are away from each other are respectively provided with a plurality of guide holes 45 that match the corresponding guide rods 51, and the ends of the guide rods 51 that are away from the clamping plates 5 are slidably installed in the corresponding guide holes 45. Under the limiting effect of the mounting grooves 44 on the clamping plates 5 and the limiting and guiding effect of the guide holes 45 on the guide rods 51, the stability of the sliding installation of the two clamping plates 5 is ensured.

[0057] like Figure 5 and Figure 6 As shown, a pressing spring 52 is provided along the axial direction of each guide rod 51 and the end of the corresponding guide hole 45 close to each other. When the pressing spring 52 is in a normal state, the ends of the two clamping plates 5 close to each other are located in the clamping port 43. Under the pressing action of the pressing spring 52, the side of the two clamping plates 5 close to each other always tightly clamps the ends of the aluminum strips of different thicknesses from both sides, thereby improving the clamping and fixing effect of the ends of the aluminum strips, thereby ensuring the stability of the auxiliary reel 42 when winding or releasing the aluminum strip.

[0058] like Figure 5 and Figure 6 As shown, in this embodiment, both ends of the clamping opening 43 are provided with limit blocks 6, which are used to limit the ends of the aluminum strip from both sides to prevent the ends of the aluminum strip from being offset when clamped between the two clamping plates 5, which would affect the neat winding of the aluminum strip by the auxiliary reel 42. The two limit blocks 6 are slidably installed in the clamping opening 43 along the length direction of the clamping opening 43, and there is a certain adjustment distance between the two limit blocks 6 and the clamping plates 5 and the ends close to them. The distance between the two limit blocks 6 can be adjusted to limit the aluminum strips of different widths, thereby improving the scope of application. Figure 5 and Figure 6 As shown, in order to realize the sliding installation of the two limit blocks 6, a limit rod 61 arranged along the length direction of the clamping port 43 is respectively provided at one end of the two limit blocks 6 away from each other, and a limit hole 46 cooperating with the limit rod 61 is provided at both ends of the clamping port 43. The limit rod 61 is slidably installed in the limit hole 46 to ensure the stability of the sliding installation of the two limit blocks 6.

[0059] like Figure 5 and Figure 6As shown, in order to adjust and fix the distance between the two limit blocks 6, a sliding hole 62 is provided at both ends of each limit block 6 along the width direction of the clamping opening 43, a sliding rod 63 is slidably installed in the sliding hole 62, and an adjusting member is connected between the ends of the two sliding rods 63 on the limit block 6 that are away from each other and the clamping plate 5. In this embodiment, the adjusting member includes an adjusting rod 64 provided along the length direction of the clamping opening 43, and the end of the adjusting rod 64 away from the clamping plate 5 is connected to the corresponding sliding rod 63 to form an L shape, and the two ends of the clamping plate 5 are respectively provided with adjusting holes 53 arranged along the length direction thereof and matched with the corresponding adjusting rod 64, and the end of the adjusting rod 64 away from the sliding rod 63 is slidably installed in the corresponding adjusting hole 53. An elastic snap 641 is provided on the side wall of the end of the adjusting rod 64 away from the sliding rod 63, and a plurality of adjusting clamp holes 54 arranged in an array along the length direction thereof are provided at both ends of the side wall of the clamping plate 5 close to the opening of the clamping opening 43, and the adjusting clamp holes 54 are connected with the corresponding adjusting holes 53 and matched with the corresponding elastic snap 641. When the position of the adjusting rod 64 is moved, the limit block 6 is driven to slide in the clamping port 43 by the sliding rod 63, so that the distance between the two limit blocks 6 can be adjusted. Then, the elastic snap button 641 is clamped in the adjusting clamp hole 54 at the corresponding position to fix the distance between the two limit blocks 6, so that it can limit the two sides of aluminum strips of different widths.

[0060] like Figure 5 or Figure 6 As shown, since the clamping opening 43 is provided, in order to ensure that there is sufficient space in the clamping opening 43, it is convenient to install the clamping plate 5, the stopper 6 and other components, and the end of the aluminum strip must be clamped for a certain length to ensure the stability of the fixation of the end of the aluminum strip, the auxiliary reel 42 needs to have a certain wall thickness, and a large wall thickness will affect the heat transmission of the heating rod 75 in the auxiliary reel drive shaft 73. Therefore, a plurality of heat-conducting holes 47 are arranged in a circumferential array on the inner wall of the auxiliary reel 42, and the axis is arranged along the radial direction of the auxiliary reel 42. One end of the heat-conducting hole 47 is connected to the inner cavity of the auxiliary reel 42, and the other end passes through the outer wall of the auxiliary reel 42, and a plurality of groups of heat-conducting holes 47 are arranged in an array along the axis direction of the auxiliary reel 42. In this way, the heat-conducting holes 47 are used to accelerate the heat transmission, so as to ensure that the heat of the heat-conducting cavity 74 on the auxiliary reel drive shaft 73 can be quickly and evenly transmitted to the aluminum strip wound on the outer wall of the auxiliary reel 42, so as to achieve uniform annealing of the end of the aluminum strip always wound on the outer wall of the auxiliary reel 42.

[0061] like Figure 2As shown, in this embodiment, a plurality of vertically arranged support rods 332 are arranged in a rectangular array at the bottom of the support seat 33, and a plurality of vertically arranged guide cylinders 21 with openings at the upper ends are arranged on the material transport trolley 2, and the lower ends of the support rods 332 are vertically slidably installed in the corresponding guide cylinders 21. A vertically arranged tension spring 333 is arranged between the lower end of the support rod 332 and the inner bottom wall of the guide cylinder 21. In the initial state, under the action of the tension spring 333, the axis of the discharge cylinder 31 and the axis of the discharge drive shaft 72 are located in the same horizontal plane, ensuring that when aluminum coils 32 of various specifications are annealed, the discharge drive shaft 72 can be accurately inserted into the discharge cylinder 31 and clamped therewith, without adjusting the height of the discharge drive shaft 72, thereby simplifying the structure of the drive mechanism 7 in the annealing furnace 1. In addition, as the aluminum coil 32 on the unloading cylinder 31 is released and reeled, the support seat 33 is always in contact with the outer wall of the aluminum coil 32 under the action of the tension spring 333, providing support for the aluminum coil 32, preventing the aluminum coil 32 from hanging in the air on the unloading drive shaft 72, reducing the load on the unloading drive shaft 72, and increasing the life of the unloading drive shaft 72.

[0062] like Figure 2 and Figure 3 As shown, the aluminum coil 32 is wound on the discharge barrel 31 after annealing. In order to ensure that the aluminum coil 32 is neatly wound after annealing on the discharge barrel 31 and to prevent the aluminum strip from being offset and affecting the next process, an anti-deflection shaft 34 with an axis parallel to the axis of the discharge barrel 31 is positioned and rotatably installed at both ends of the support seat 33. An anti-deflection clamp 35 is provided at one end of the anti-deflection shaft 34 away from the support seat 33. The upper end of the anti-deflection clamp 35 is located below the discharge barrel 31, and the aluminum strip is limited by the anti-deflection clamp 35. When placing the aluminum coil 32 on the support seat 33 or removing the aluminum coil 32 from the support seat 33, the anti-deflection shaft 34 can be rotated to rotate the anti-deflection clamp 35 to a vertical downward position to prevent the anti-deflection clamp 35 from affecting the placement or removal of the aluminum coil 32.

[0063] like Figure 2 and Figure 3 As shown, in addition, in order to realize the anti-deflection card plate 35 to limit the aluminum strips of different widths, the lower end of the anti-deflection card plate 35 is connected to the anti-deflection shaft 34 in a limited sliding manner, and its sliding direction is set along the length direction of the anti-deflection shaft 34. A tension spring 36 set along the length direction of the anti-deflection shaft 34 is provided between the side where the anti-deflection card plate 35 and the support seat 33 are close to each other, and the tension spring 36 is sleeved outside the anti-deflection shaft 34. Under the tension of the tension spring 36, the anti-deflection card plate 35 always abuts against the side wall of the aluminum coil 32, ensuring the anti-deflection effect of the anti-deflection card plate 35 on the aluminum strips of different widths. The tension spring 36 is sleeved outside the anti-deflection shaft 34, and the anti-deflection shaft 34 plays a certain supporting role on the tension spring 36, avoiding the deformation of the tension spring 36 along its radial direction after long-term work, and effectively ensuring the use effect and service life of the tension spring 36.

[0064] Working principle and use method of the present invention:

[0065] The aluminum coil 32 to be annealed is placed in the arc-shaped support groove 331 of the support seat 33, and the distance between the two limit blocks 6 in the clamping port 43 is adjusted according to the width of the aluminum coil 32, and the end of the aluminum strip pulled from the aluminum coil 32 of the discharge barrel 31 is inserted into the clamping port 43, and the end of the aluminum strip is clamped and fixed by two clamping plates 5. The two limit blocks 6 prevent the aluminum strip from being deflected from both sides to ensure that the end of the aluminum strip will not loosen and tumble. After the material transport trolley 2 enters the annealing furnace 1, the driving frame 71 is moved as a whole toward the direction close to the material transport trolley 2, and a plurality of material discharge drive shafts 72 and auxiliary roll drive shafts 73 are inserted into the corresponding discharge barrel 31 and auxiliary roll 42 and clamped therewith, and finally the sealing baffle door 14 is closed, and the automatic operation and linkage are controlled through the control panel 15.

[0066] The heating rods 75 in the heating chamber 11 and the heat-conducting chamber 74 are working to heat, and the auxiliary winding motor 96 is working, so that the auxiliary winding drive shaft 73 drives the auxiliary winding drum 42 to rotate and rewind the aluminum strip on the aluminum coil 32, and the unwinding drive shaft 72 drives the unwinding drum 31 to rotate and loosen the aluminum strip on the aluminum coil 32, and the aluminum coil 32 on the unwinding drum 31 is rewound onto the auxiliary winding drum 42. In this process, the auxiliary winding meter meter 97 calculates the length of the aluminum strip wound on the auxiliary winding drum 42, and the unwinding meter meter 84 calculates the loose length of the aluminum coil 32 on the unwinding drum 31. When the remaining amount of the aluminum coil 32 on the unwinding drum 31 reaches the set value, the unwinding meter meter 84 controls the auxiliary winding motor 96 to stop working, and the auxiliary winding meter meter 97 controls the unwinding motor 83 to drive the unwinding drum 31 to rotate in the opposite direction to rewind the aluminum strip. The unloading drive shaft 72 rotates to reel in the aluminum strip, and the auxiliary roll drive shaft 73 rotates to loosen the aluminum strip, and the aluminum roll 32 on the auxiliary reel 42 is rewound onto the unloading drum 31. During this process, the auxiliary roll meter meter 97 calculates the length of the aluminum strip loosened by the auxiliary reel 42, and the unloading meter meter 84 calculates the length of the aluminum strip wound by the unloading drum 31. When the remaining aluminum strip on the auxiliary reel 42 reaches the set value, the unloading meter meter 84 controls the auxiliary roll motor 96 to start, and the auxiliary roll meter meter 97 controls the unloading motor 83 to stop working.

[0067] In this way, a plurality of aluminum coils 32 are repeatedly released and wound in the annealing furnace 1. The aluminum strip is subjected to single-layer annealing in the heating chamber 11 during the release and winding process, and the heating rod 75 in the heat conduction chamber 74 anneals the ends of the aluminum strip that are always wound around the auxiliary reel 42 and the unwinding reel 31 from the inside to the outside, which not only improves the uniformity of the annealing of the aluminum coil 32, but also improves the annealing efficiency of the aluminum coil 32, while ensuring that the annealing time of the aluminum strip is sufficient, thereby effectively ensuring the annealing quality of the aluminum strip.
