Description

Technical Field

[0001] This utility model relates to the technical field of aluminum coil production equipment, and in particular to an annealing device for aluminum coils. Background Technology

[0002] Annealing is a metal heat treatment process that involves slowly heating a metal to a certain temperature, holding it for a sufficient time, and then cooling it at a suitable rate. The purpose is to reduce hardness, improve machinability, reduce residual stress, stabilize dimensions, and reduce deformation and cracking tendency; refine grains, adjust microstructure, and eliminate structural defects. More precisely, annealing is a heat treatment process for materials, including both metallic and non-metallic materials. Furthermore, the annealing objectives for new materials differ from those of traditional metal annealing. Annealing furnaces are specifically designed for annealing operations; aluminum coils require annealing during processing.

[0003] For example, patent document CN222205366U discloses an automated annealing furnace for aluminum coil annealing, relating to the field of aluminum coil technology. The equipment includes a main body, an annealing furnace body, and a drive body. When aluminum coils need to be placed, the annealing temperature and time are set via a setting plate. A temperature sensor monitors the temperature inside the annealing furnace body in real time. The aluminum coils are placed on placement seats. A controller controls an electric push rod to operate. A moving rod connected to one side of the electric push rod moves a second baffle along with the operation of the electric push rod. A support plate fixed to one end of the second baffle moves the placement seats along with the movement of the second baffle. A slider installed at the bottom of the support plate slides in a groove along with the movement of the support plate, allowing the aluminum coils to move smoothly and evenly into the annealing furnace body for annealing. No manual pushing of the second baffle is required, saving time and effort, and providing strong automation.

[0004] However, the device lacks a mechanism for fixing the aluminum coil, which cannot guarantee the stability of the aluminum coil's position during the annealing process, resulting in low safety. Furthermore, the annealing furnace of this device cannot guarantee uniform heating of the aluminum coil, which can easily affect the annealing effect of the aluminum coil. Utility Model Content

The rotating shaft is rotatably connected to the top of the inner wall of the tank body. Several fan blades are fixedly connected to the bottom of the rotating shaft.

[0011] Preferably, the limiting mechanism includes several buttons, which are slidably connected to the top of the turntable. A connecting rod is fixedly connected to the bottom of the buttons.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7As shown, an annealing apparatus for aluminum coils includes a base 1. A rotating mechanism is provided on the top of the base 1. The rotating mechanism includes a turntable 303, which is rotatably connected to the top of the base 1. A tank 302 is rotatably connected to the turntable 303. A clamping mechanism is provided on the turntable 303. The clamping mechanism includes several support plates 701, which are slidably connected to the turntable 303. Two ratchet plates 702 are fixedly connected to the support plates 701. A column 703 is fixedly connected to the support plates 701. A conical block 704 is slidably connected inside the column 703. The bottom of the conical block 704 is fixedly connected to the turntable 303. Two clamping blocks 705 are slidably connected to the conical block 704 and are slidably connected inside the column 703. The bottom of the support plates 701 is fixedly connected to... Several first springs 706 are fixedly connected to the turntable 303 at their bottoms. When the support plate 701 descends, it will cause the column 703 to descend. The conical block 704 will push the clamping block 705 outward to clamp the center hole of the aluminum coil. Several anti-slip protrusions 10 can enhance the friction on the surface of the aluminum coil to ensure the stability of the aluminum coil during the annealing process and enhance safety. The top of the base 1 is provided with a drive mechanism, and a transmission mechanism is provided on one side of the drive mechanism. The drive mechanism is used to drive the transmission mechanism. Several ventilation slots 5 are opened inside the tank 302. The inner wall of the tank 302 is fixedly connected with an electric heating wire 6. The turntable 303 is provided with a limit mechanism. The tank 302 is provided with a switch mechanism. Several anti-slip protrusions 10 are fixedly connected to the clamping block 705.

[0028] The rotating mechanism includes several supports 301, which are fixedly connected to the surface of the tank 302. The bottom of the supports 301 is fixedly connected to the base 1, and the supports 301 fix the tank 302.

[0029] The drive mechanism includes a motor 201, which is fixedly connected to the top side of the base 1. The output end of the motor 201 is fixedly connected to a first bevel gear 202, which meshes with the surface of the turntable 303. The first bevel gear 202 has a timing belt 203, and the other end of the timing belt 203 contacts a driven wheel 204. The motor 201 drives the first bevel gear 202 to rotate, and the rotation of the first bevel gear 202 drives the driven wheel 204 to rotate through the timing belt 203.

[0030] The transmission mechanism includes a driven shaft 401, which is fixedly connected to the driven wheel 204 on the side near the tank 302. The other end of the driven shaft 401 is fixedly connected to a second bevel gear 402, and a third bevel gear 403 meshes with the second bevel gear 402. A rotating shaft 404 is connected through the third bevel gear 403. The rotating shaft 404 is rotatably connected to the top of the inner wall of the tank 302. Several fan blades 405 are fixedly connected to the bottom of the rotating shaft 404. The rotation of the driven wheel 204 drives the second bevel gear 402 to rotate through the driven shaft 401. The rotation of the second bevel gear 402 drives the rotating shaft 404 to rotate through the third bevel gear 403. The rotation of the rotating shaft 404 drives the several fan blades 405 to rotate and blow air downwards.

[0031] The limiting mechanism includes several buttons 801, which are slidably connected to the top of the turntable 303. A connecting rod 802, U-shaped, is fixedly connected to the bottom of each button 801. A crossbar is fixedly connected to the connecting rod 802. Several sliders 803 are slidably connected to the turntable 303. A groove 804 is provided on each slider 803. The crossbar on the connecting rod 802 passes through the groove 804 and is slidably connected to the slider 803. A second spring 805 is fixedly connected to the side of the slider 803 furthest from the center of the base 1. The other end of the second spring 805 is fixedly connected to the turntable 303. The slider 803 is close to the base 1. One side of the center plate is engaged with the ratchet plate 702. The support plate 701 will be lowered by the pressure of the aluminum coil, and the ratchet plate 702 will also be lowered. After the support plate 701 stops descending, the slider 803 will engage in the groove of the ratchet plate 702 to limit the height of the support plate 701. When the aluminum coil needs to be removed, press the button 801. The button 801 descends, which drives the connecting rod 802 to descend. The descending of the connecting rod 802 will drive the slider 803 to move away from the support plate 701. The tip of the slider 803 will disengage from the groove on the ratchet plate 702. At the same time, the clamping block 705 will retract, thereby releasing the lock on the aluminum coil.

[0032] The switching mechanism includes a movable door 901, which is hinged to the side of the tank 302 away from the motor 201. An observation window 902 and a handle 903 are fixedly connected to the movable door 901. The operator can observe the annealing status of the aluminum coil inside the tank 302 in real time through the observation window 902.

[0033] Working principle: When using this device, the operator first opens the movable door 901 and places the aluminum coil on the support plate 701. The support plate 701 will descend under the pressure of the aluminum coil, and the ratchet plate 702 will also descend accordingly. After the support plate 701 stops descending, the slider 803 will engage in the groove of the ratchet plate 702 to limit the height of the support plate 701. As the support plate 701 descends, the conical block 704 will push the clamping block 705 outward to clamp the center hole of the aluminum coil. Several anti-slip protrusions 10 can enhance the friction on the surface of the aluminum coil to ensure the stability of the aluminum coil during the annealing process and enhance safety.

[0034] Then, the motor 201 and the heating wire 6 are started. The motor 201 drives the first bevel gear 202 to rotate. The rotation of the first bevel gear 202 drives the turntable 303 to rotate. At the same time, it drives the driven wheel 204 to rotate through the synchronous belt 203. The rotation of the driven wheel 204 drives the second bevel gear 402 to rotate through the driven shaft 401. The rotation of the second bevel gear 402 drives the rotating shaft 404 to rotate through the third bevel gear 403. The rotation of the rotating shaft 404 drives several fan blades 405 to rotate. When the fan blades 405 rotate, they blow air downwards. The opening at the top of the ventilation slot 5 is within the radius of the rotation of the fan blades 405. Therefore, the air at the bottom of the tank 302 will be transported upward through several ventilation slots 5 due to the negative pressure and then transported back into the tank 302 from the top of the ventilation slots 5. This drives the air inside the tank 302 to circulate, avoiding uneven heating inside the tank 302, which would affect the annealing effect of the aluminum coil.

[0035] When the aluminum coil needs to be removed after the annealing process is completed, press button 801. Button 801 descends, causing connecting rod 802 to descend. The descent of connecting rod 802 causes slider 803 to move away from support plate 701. The tip of slider 803 will disengage from the groove on ratchet plate 702, and clamping block 705 will retract, thereby releasing the lock on aluminum coil.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
