Description

Technical Field

[0001] This utility model relates to the field of new energy lithium battery component technology, specifically a densely packed material rack for an annealing furnace. Background Technology

[0002] Battery aluminum foil is a material used in battery manufacturing, primarily for protecting and encapsulating battery cells. It is typically made of aluminum or aluminum alloys, possessing good electrical conductivity and corrosion resistance. The aluminum foil requires an annealing process during manufacturing, necessitating its placement in an annealing furnace.

[0003] Chinese invention patent CN116103483A, published on May 12, 2023, discloses an annealing support frame for rolled materials. The frame includes a triangular frame, a first cover plate, a second cover plate, a central ring, and a round steel column. The first and second cover plates are welded to the sides and corners of the triangular frame, respectively, with the second cover plate aligned with the corners. The central ring is located inside the triangular frame. The ends of the first and second cover plates away from the triangular frame are welded to the central ring. A through hole is provided on the triangular frame, through which the round steel column passes. Circular blocks are fixedly connected to both ends of the round steel column. By welding multiple first and second cover plates at intervals onto the triangular frame and the central ring, the main skeleton of the annealing support frame is formed. Sufficiently large gaps exist between the central ring, between the first and second cover plates, and between the first and second cover plates themselves, ensuring strong ventilation and facilitating the circulation of gas inside the annealing furnace, thereby ensuring a good annealing effect for the rolled material.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing roll support racks cannot support the annealing requirements of multiple heavy aluminum foil rolls. Therefore, it is necessary to design a support rack that can withstand greater weight and place more aluminum foil rolls in a limited space. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing coil support racks cannot support multiple heavy aluminum foil rolls for annealing. Therefore, it is necessary to design a support rack that can withstand greater weight and place more aluminum foil rolls in a limited space. This invention provides a close-packed material rack for annealing furnaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a close-packed material rack for an annealing furnace, comprising a movable base; a fixed base slidably connected to the lower end of the movable base; a plurality of distributed load-bearing support plates fixedly connected to the movable base; a horizontal support plate fixedly connected to the upper end of the distributed load-bearing support plates; and an arc groove formed on the horizontal support plate.

[0008] Furthermore, the fixed base includes a lower support row, a middle support row, and an upper support row; the lower support row and the upper support row are symmetrically fixed to the upper and lower surfaces of the middle support row.

[0009] Furthermore, the movable base has symmetrically threaded holes on both sides for connecting multiple first fasteners; a side panel is sleeved on the first fastener; an L-shaped plate is fixed to the side panel; multiple positioning pins are inserted between the L-shaped plate and the side panel; rollers are sleeved on the positioning pins; and multiple second fasteners are threaded holes on the side panel.

[0010] The closely spaced material rack for an annealing furnace provided by this utility model has the following beneficial effects:

[0011] 1. This utility model achieves a stable annealing process for supporting heavy aluminum foil rolls by placing them in an arc groove using a gantry crane, and then distributing the weight evenly to the moving base through a horizontal support plate and a distributed load-bearing support plate, thereby evenly transferring the weight to the fixed base.

[0012] 2. This utility model uses a roller and the lower surface of the intermediate support row to roll and rub together, so that in the cooling state, the distance between the two movable bases can be adjusted according to the length of the aluminum foil roll to accurately support and fix the aluminum foil roll. At the same time, the lower end of the roller limits the movement of the movable bases so that they will not tip over and cause danger when adjusting them. Furthermore, the distance between the two movable bases can be adjusted while shortening the support tube of the aluminum foil roll, thereby accommodating more aluminum foil rolls for support and annealing.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-4 As shown, an annealing furnace densely packed material rack includes a movable base 4; a fixed base for fixing and bearing weight is slidably connected to the lower end of the movable base 4; then, multiple distributed load-bearing support plates 5 are fixedly connected to the upper surface of the movable base 4; a horizontal support plate 6 is fixedly connected to the upper end of the distributed load-bearing support plate 5; an arc groove 7 is opened on the horizontal support plate 6, and a heavy aluminum foil roll is placed in the arc groove 7 by a gantry crane, so that the weight is evenly distributed to the movable base 4 through the horizontal support plate 6 and the distributed load-bearing support plates 5, and then evenly transferred to the fixed base, thereby realizing the stable support of the heavy aluminum foil roll in the annealing process.

[0023] The fixed base is made of a three-layer structure welded together, consisting of a lower support row 1, a middle support row 2, and an upper support row 3. The lower support row 1 and the upper support row 3 are symmetrically fixed to the upper and lower surfaces of the middle support row 2, making it a rigid whole that can withstand more of the annealing support weight of the aluminum foil roll.

[0024] Multiple bolts belonging to the first fastener 8 are threadedly connected to the symmetrically perforated sides of the movable base 4; then, a side panel 9 is sleeved on the first fastener 8; an L-shaped plate 10 is fixed to the side panel 9; multiple positioning pins 11 are inserted between the L-shaped plate 10 and the side panel 9; rollers 12 are sleeved on the positioning pins 11, so that the side panel 9, L-shaped plate 10, positioning pins 11 and rollers 12 can be quickly assembled and disassembled as a whole through the first fastener 8; multiple second fasteners 14 are threadedly connected to the perforated sides of the side panel 9; the rollers 12 are connected to the lower surface of the intermediate support row 2 through rolling friction, so that in cold... In the unstressed state, the distance between the two movable bases 4 can be adjusted according to the length of the aluminum foil roll to precisely support and fix the aluminum foil roll. At the same time, the lower end limit of the roller 12 prevents the movable base 4 from tipping over and causing danger when adjusting it. The distance between the two movable bases 4 can also be adjusted by shortening the support tube of the aluminum foil roll, so as to further accommodate more aluminum foil rolls for support annealing. The second fastener 14 squeezes and clamps the middle support row 2 to achieve the detachable fixed movable base 4, making it safer to use and able to resist a certain lateral force, so that it always remains vertical and fixed.

[0025] The horizontal support plate 6 has a vertical arc groove 7 with a dividing groove 13. The dividing groove 13 makes it easy to visually position the aluminum foil roll when the crane is hoisting it, preventing it from going beyond the center line and causing unstable force. It also allows the hoisting structure to pull out the middle tube of the aluminum foil roll.

[0026] The middle support row 2 and the upper support row 3 are in contact with the sliding surface of the movable base 4. The sliding surface contact makes it easy to change the position of the movable base 4 on the middle support row 2 and the upper support row 3, thereby allowing for effortless position adjustment.
