Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, specifically to a material rack for annealing aluminum foil blanks. Background Technology

[0002] Aluminum ingots undergo homogenization, hot rolling, cold rolling, and intermediate annealing to form a billet. Aluminum foil billets are typically in the form of coiled aluminum material, used for further rolling into aluminum foil. Annealing of aluminum foil billets is a key process in aluminum foil production, directly affecting the mechanical properties and surface quality of the aluminum foil. During annealing, aluminum foil is supported by a rack and placed in an annealing furnace.

[0003] Currently used annealing racks include cage racks and combined racks. Cage racks have a high space utilization rate under fixed product size conditions. Existing combined racks have improved adaptability through vertical height adjustment, but their overall structure has technical defects such as complex disassembly and assembly. Especially when multiple racks are configured, it will significantly reduce the furnace loading efficiency of the annealing process. Summary of the Invention

[0004] This utility model addresses the problem of complex assembly and disassembly of modular material racks by providing a material rack for annealing aluminum foil billets. It enables quick assembly and disassembly of modular annealing material racks, thereby improving furnace loading efficiency.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A material rack for annealing aluminum foil blanks includes support rods and connectors. There are two support rods, and connectors are provided between the left and right ends of each support rod. The left connector includes a vertical cylinder and a limiting rod. Each support rod has a vertical cylinder connected to its left end. The lower end of the vertical cylinder is closed and connected to a connecting rod, while the upper end is open. The connecting rod has a limiting hole. A connecting cylinder connects the two vertical cylinders. Limiting rods are provided in both the front and rear parts of the connecting cylinder. The two limiting rods are driven by a driving component to move relative to or away from each other. Each limiting rod has a through hole on the peripheral wall of the vertical cylinder on the same side. The end of each limiting rod extends into or out of the corresponding vertical cylinder through the through hole on the same side. The distance from the limiting hole to the upper end of the connecting rod is equal to the distance from the through hole to the upper end of the vertical cylinder.

[0007] Furthermore, the connecting rod is a rectangular rod that matches the inner diameter of the vertical cylinder, and the length of the connecting rod is less than the inner height of the vertical cylinder. Each of the limiting holes penetrates the front and rear sides of the connecting rod. The through hole and the limiting hole are both circular holes with the same diameter, and the limiting rod is a circular rod with a diameter that matches the diameter of the through hole.

[0008] Furthermore, the driving component on the left includes a partition, a movable rod, and a rotating rod. A partition is fixedly spaced in the middle of the connecting cylinder on the left. A rotating rod is provided inside the connecting cylinder, with its two ends movably penetrating through the two partitions respectively. The rotating rod is rotatably connected to the two partitions. Movable rods are slidably provided back and forth in the connecting cylinder on the opposite sides of the two partitions. Limit rods are connected to the opposite ends of the two movable rods. External threads one and external threads two with opposite directions are respectively provided on the peripheral walls of the rotating rods on the opposite sides of the two partitions. The front part of the rotating rod is threaded to the front movable rod through external thread one, and the rear part is threaded to the rear movable rod through external thread two. The rotating rod is driven to rotate by the driving assembly.

[0009] Furthermore, the drive assembly on the left side includes a worm gear and a worm. The rotating rod between the two partitions is fitted with a worm gear. One end of the worm rotates through the right side plate of the connecting cylinder, and the other end moves through the left side plate of the connecting cylinder. The worm meshes with the worm gear.

[0010] Furthermore, when the opposite ends of the two movable rods inside the connecting cylinder on the left are in contact with the partition on the same side, the opposite ends of the two limiting rods are both located inside the connecting cylinder. When the opposite ends of the two movable rods are in contact with the vertical cylinder on the same side, the opposite ends of the two limiting rods pass through the corresponding through holes and are located inside the vertical cylinder on the same side.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] This utility model can be used as a material rack unit. According to the required number of aluminum coils to be loaded, an appropriate number of material rack units can be selected for vertical connection. Each connecting rod of the upper material rack unit extends into a corresponding vertical cylinder of the lower adjacent material rack unit, so that the driving component drives each limiting rod to extend into the limiting hole of the corresponding connecting rod. Each connecting rod of the upper material rack unit is limited in the corresponding vertical cylinder of the lower material rack unit, and the connection of adjacent material rack units is completed. This utility model can realize the connection of multiple material rack units, and the connection is quick and convenient.

[0013] During disassembly, simply ensure that the ends of the two limiting rods inside the corresponding connecting cylinder are positioned inside the connecting cylinder. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-5 As shown, a material rack for annealing aluminum foil blanks includes support rods 1 and connectors. There are two support rods 1, each a rectangular rod, with a groove 8 on each rod. Multiple grooves 8 on the front support rod 1 correspond one-to-one with multiple grooves 8 on the rear support rod 1. The grooves 8 are V-shaped grooves. Connectors are provided between the left and right ends of the two support rods 1, and the two connectors are symmetrical. The left connector includes a vertical cylinder 2 and a limiting rod 3. Each support rod 1 has a vertical cylinder 2 connected to its left end. The vertical cylinder 2 is a rectangular cylinder, and its lower... The upper end is closed by a connecting rod 5 and the upper end is open. The connecting rod 5 is provided with a limiting hole 6. The connecting rod 5 is a rectangular rod. A connecting cylinder 4 is connected between the two vertical cylinders 2. The connecting cylinder is a rectangular cylinder with open ends. Limiting rods 3 are provided in the front and rear parts of the connecting cylinder 4. The two limiting rods 3 are driven by a driving component to move relative to or away from each other. Each limiting rod 3 has a through hole 7 on the peripheral wall of the vertical cylinder 2 on the same side. The end of each limiting rod 3 extends into or out of the corresponding vertical cylinder 2 through the through hole 7 on the same side. The distance from the limiting hole 6 to the upper end of the connecting rod 5 is equal to the distance from the through hole 7 to the upper end of the vertical cylinder 2.

[0022] Each connecting cylinder 4 has a lifting lug 16 attached to its outer top surface.

[0023] The connecting rod 5 is a rectangular rod that matches the inner diameter of the vertical cylinder. The length of the connecting rod 5 is less than the inner height of the vertical cylinder 2. Each of the limiting holes 6 penetrates the front and rear sides of the connecting rod 5. The through hole 7 and the limiting hole 6 are both circular holes with the same diameter. The limiting rod 3 is a circular rod with a diameter that matches the diameter of the through hole 7.

[0024] The driving components on the left and right connecting cylinders 4 are symmetrical. The driving component on the left side includes a partition 9, a movable rod 10, and a rotating rod 11. The partition 9 is fixedly installed in the middle of the connecting cylinder 4. The partition 9 is a rectangular plate that is fixedly connected to the inner side of the connecting cylinder 4. The connecting cylinder 4 is provided with a rotating rod 11 that movably passes through the two partitions 9 at both ends. The rotating rod 11 is rotatably connected to the two partitions 9. Movable rods 10 are slidably installed back and forth in the connecting cylinder 4 on the opposite sides of the two partitions 9. The movable rod 10 is a rectangular rod that slides in contact with the inner wall of the connecting cylinder 4. The opposite ends of the two movable rods 10 are connected to limit rods 3. The circumferential walls of the rotating rods 11 on the opposite sides of the two partitions 9 are respectively provided with external threads 12 and 13 with opposite thread directions. The front part of the rotating rod 11 is connected to the front movable rod 10 through external thread 12, and the rear part is connected to the rear movable rod 10 through external thread 13. The rotating rod 11 is driven to rotate by the driving assembly.

[0025] The drive assembly on the left includes a worm gear 14 and a worm 15. The rotating rod 11 between the two partitions 9 is fitted with a worm gear 14. One end of the worm 15 rotates through the right side plate of the connecting cylinder 4, and the other end moves through the left side plate of the connecting cylinder 4 and is connected to a rotating plate. The worm 15 meshes with the worm gear.

[0026] When the opposite ends of the two movable rods 10 in the connecting cylinder 4 on the left are in contact with the partition 9 on the same side, the opposite ends of the two limiting rods 3 are located in the connecting cylinder 4. When the opposite ends of the two movable rods 10 are in contact with the vertical cylinder 2 on the same side, the opposite ends of the two limiting rods 3 pass through the corresponding through hole 7 and are located in the vertical cylinder 2 on the same side.

[0027] In use, one unit of this invention serves as a material rack unit. Depending on the quantity of aluminum coils to be carried, an appropriate number of material rack units are selected for vertical connection. First, the worm gear 15 on each material rack unit is rotated, causing the worm gear 15 to drive the meshed worm wheel 14 to rotate. The rotating rod 11 rotates with the worm wheel, causing the two movable rods 10 inside the connecting cylinder 4 to move relative to each other, ensuring that the ends of the two limiting rods 3 within the same connecting cylinder 4 are both located inside the connecting cylinder 4. Then, each connecting rod 5 of the upper material rack unit extends into the vertical cylinder 2 of the adjacent lower material rack unit. Since the distance from the limiting hole 6 to the upper end of the corresponding connecting rod 5 is equal to the distance from the through hole 7 to the upper end of the corresponding vertical cylinder 2, when the closed end of the vertical cylinder of the upper material rack unit contacts the lower... When the upper end of the vertical cylinder is reached, the limiting hole 6 on each connecting rod 5 is opposite to the opening of the through hole 7 on the vertical cylinder 2. Then, the worm 15 on each connecting cylinder 4 on the lower material rack unit is rotated in the opposite direction, so that the worm 15 drives the meshed worm wheel 14 to rotate in the opposite direction. The rotating rod 11 rotates in the opposite direction with the worm wheel, and the two movable rods 10 in the connecting cylinder 4 move in opposite directions until the opposite ends of the two movable rods 10 contact the vertical cylinder 2 on the same side. At this time, the opposite ends of the two limiting rods 3 pass through the corresponding through hole 7 and are located in the vertical cylinder 2 on the same side. The end of each limiting rod 3 extends into the limiting hole 6 on the connecting rod 5 in the vertical cylinder 2. The connecting rod 5 is limited in the vertical cylinder 2, and the connection of the upper and lower adjacent material rack units is completed.

[0028] During disassembly, rotate the worm gear 15 so that the ends of the two limiting rods 3 inside the corresponding connecting cylinder 4 are located inside the connecting cylinder 4, thereby releasing the connection limit of the adjacent material rack unit and facilitating disassembly.

[0029] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
