[0037] Reference Figure 2 The unwinding mechanism 1 includes an unwinding frame 11 and an unwinding roller 12. The unwinding roller 12 is horizontally rotatably connected to the unwinding frame 11. The roll material is wound around the unwinding roller 12. It should be noted that the roller surface of the unwinding roller 12 is circular and seamlessly set so that the ultra-thin metal material roll material remains flat during the unwinding process.
[0038] Reference Figure 2 The unwinding mechanism 1 also includes a first material changing component 13, which is disposed on the unwinding frame 11 to support another roll of material and transfer it to the unwinding roller 12, thereby achieving rapid material changing during the unwinding operation. Specifically, the first material changing component 13 includes an unwinding support 131, an unwinding guide rail 132, and a second driving member 133. The unwinding guide rail 132 is fixedly disposed at the bottom of the unwinding frame 11 in a direction perpendicular to the unwinding direction. The unwinding support 131 supports another roll of material and is slidably connected to the unwinding frame 11 through the unwinding guide rail 132.

In this embodiment, the second driving member 133 is driven by a motor screw, which is a conventional setting for driving reciprocating movement and will not be described in detail here.
[0039] When one roll of material is being unwound, the unwinding support 131 is located on one side of the unwinding position. Another roll of material is pre-placed on the unwinding support 131. After the unwinding operation of the unwound material is completed, the second drive unit 133 drives the unwinding support 131 to move to the unwinding position and engage the unwinding roller 12.

It should be noted that the first drive unit 5132 is electrically connected to the control mechanism 53, and the control mechanism 53 controls the unwinding and material changing actions according to the actual unwinding situation.
[0040] Reference Figure 3 and Figure 4 After the coil material exits the coil, it passes through the first tensioning mechanism 51 before entering the stress-relieving furnace 2. Specifically, the first tensioning mechanism 51 includes a first support frame 511, a first tensioning roller 512, and a first adjusting component 513. The first support frame 511 is located between the unwinding frame 11 and the stress-relieving furnace 2 to support the first tensioning roller 512 and the first adjusting component 513. The number of first tensioning rollers 512 is set to several, and the several first tensioning rollers 512 are horizontally parallel and rotatably connected to the first support frame 511. The several first tensioning rollers 512 are arranged at intervals along the conveying direction of the coil material. The first adjusting component 513 is set on the first support frame 511. When it is necessary to adjust the tension, the first adjusting component 513 adjusts the position of the first tensioning roller 512.
[0041] With reference to Figure 4 and Figure 5 , the first adjusting assembly 513 comprises a first adjusting block 5131 and a first driving member 5132, one first tension roller 512 is rotationally connected to the first adjusting block 5131, the first adjusting block 5131 is vertically slidably connected to the first support frame 511, the first driving member 5132 is arranged on the first support frame 511 for driving the first adjusting block 5131 to vertically reciprocate, and the first driving member 5132 is electrically connected with the control mechanism 53. In the embodiment, the first driving member 5132 is arranged as a driving cylinder which is vertically fixed on the first support frame 511, and the first adjusting block 5131 is fixedly connected to the piston rod of the driving cylinder, and the stretching and contraction of the piston rod of the driving cylinder drives the first adjusting block 5131 to vertically move up and down, so as to realize the position adjustment of one first tension roller 512.
[0042] With reference to Figure 4 and Figure 5 , in order to improve the stability of the vertical up and down movement of the first adjusting block 5131, the first support frame 511 is provided with a first guide groove 6 for the reciprocating movement of the first adjusting block 5131, and the first guide groove 6 is vertically arranged to limit and guide the movement of the first adjusting block 5131.
[0043] With reference to Figure 4 and Figure 5 , the first adjusting assembly 513 further comprises a rotary mechanical arm 5133, and the other first tension roller 512 is rotationally connected to one end of the rotary mechanical arm 5133, and the other end of the rotary mechanical arm 5133 is rotationally connected to the first support frame 511, and at the same time, the rotary mechanical arm 5133 is electrically connected with the control mechanism 53, and the control mechanism 53 controls the rotary mechanical arm 5133 to perform a flipping action, so as to realize the adjustment of the position of one first tension roller 512. It should be noted that the first tension roller 512 connected to the rotary mechanical arm 5133 is not the same as the first tension roller 512 connected to the first adjusting block 5131. The first tension roller 512 adjusted in position by the driving cylinder and the first adjusting block 5131 and the first tension roller 512 adjusted in position by the rotary mechanical arm 5133 cooperate to jointly adjust the tension before entering the stress relief furnace 2, and further improve the stability of the tension adjustment.
[0044] With reference to Figure 1 and Figure 3 , after the coiled material is subjected to the heat dissipation operation in the heat dissipation furnace 3, it is wound through the second tensioning mechanism 52 and then wound in the winding mechanism 4. Similar to the first tensioning mechanism 51, the second tensioning mechanism 52 comprises a second support frame, a second tension roller and a second adjusting assembly, and the principle of the structure is the same as that of the first tensioning mechanism 51, which will not be described herein.
[0045] With reference to Figure 6The winding mechanism 4 comprises a winding guide rail 41, a winding frame 42, a winding roller 43, a winding support seat 44 and a third driving member 45. The winding guide rail 41 is arranged along a direction perpendicular to the winding direction. The third driving member 45 is arranged on the guide rail to drive the winding frame 42 to reciprocate along the length direction of the guide rail. In the embodiment, the third driving member 45 is in the form of a motorized screw rod to drive the winding frame 42. The winding roller 43 is horizontally rotatably connected to the winding frame 42. The winding support seat 44 is arranged on the winding guide rail 41 and located directly below the winding position. The winding support seat 44 supports the winding material as the winding becomes heavier. When the winding of a roll of material is completed, the third driving member 45 drives the winding frame 42 to move away from the winding position to perform the material replacement operation of winding.
[0046] It is worth mentioning that the winding frame 42, the winding roller 43 and the third driving member 45 are arranged in two groups. The two groups of winding frame 42, winding roller 43 and third driving member 45 are arranged on opposite sides of the winding support seat 44. When the winding operation on one group of winding frame 42, winding roller 43 and third driving member 45 is completed, the third driving member 45 drives the winding frame 42 and the winding roller 43 to move away from the winding position to perform the operation of taking out the material. At the same time, in the other group of winding frame 42, winding roller 43 and third driving member 45, the third driving member 45 drives the winding frame 42 and the winding roller 43 to move to the winding position to continue the winding operation. The winding operation is seamlessly connected to improve the winding efficiency.
[0047] Referring to Figure 4 The annealing production line further comprises an automatic welding mechanism 7 electrically connected with the control mechanism 53 to weld and fix the two rolls of material together. This is a conventional setting of the automatic welding structure, which will not be described here. It is worth mentioning that the automatic welding mechanism 7 only works when the two rolls of material need to be connected. In addition, power roller groups 8 are arranged on the front and back sides of the automatic welding mechanism 7. The two groups of power roller groups 8 provide conveying power for the two rolls of material that need to be welded.
[0048] The implementation principle of the stress relief annealing production line for the ultra-thin metal material is as follows: the coil of the ultra-thin metal material is unwound from the unwinding mechanism 1, enters the stress relief furnace 2 for stress relief operation, then enters the heat dissipation furnace 3 for heat dissipation operation, and finally is wound on the winding mechanism 4 to complete the heat treatment process to remove stress. In the conveying process, the first tensioning mechanism 51 adjusts the tension of the coil before entering the stress relief furnace 2, the second tensioning mechanism 52 adjusts the tension of the coil after the stress relief furnace 2, and the control mechanism 53 controls the tensioning actions of the first tensioning mechanism 51 and the second tensioning mechanism 52 respectively, so that the appropriate tension can be selected before the coil enters the stress relief furnace 2 and after the coil comes out of the stress relief furnace 2, and the heat treatment process of the ultra-thin metal material is carried out smoothly, thereby being beneficial to improve the product quality of the ultra-thin metal material. In addition, the tension of the first tensioning mechanism 51 and the second tensioning mechanism 52 can be adjusted by the control mechanism 53, and the tension can be selected and adjusted from three kilograms to three hundred kilograms, so that the annealing process production of different ultra-thin metal materials can be applied, and the applicability is strong.
