[0020] like Figure 1-Figure 3As shown, the utility model is an automatic fixing device for unwinding a rolled foil, characterized in that: it includes a fixing frame 1 and a foil reel 8; a rotating shaft 2 is movably fixed on the fixing frame 1; a fixing mechanism 3 is provided on the side of the rotating shaft 2 away from the fixing frame 1; the rotating shaft 2 passes through and fixes the fixing mechanism 3; a foil reel 8 is installed on the outer side of one end of the fixing mechanism 3; a driving mechanism 4 for driving the rotating shaft 2 to rotate is provided on the end of the rotating shaft 2 away from the fixing mechanism 3; a blocking component 6 is provided on the fixing frame 1 at one side of the rotating shaft 2.

[0021] like Figure 1 The shaft 2 shown is also sleeved with a sleeve 201, and the shaft 2 is fixed to the fixing frame 1 through the sleeve 201. The fixing frame 1 plays the role of fixing the shaft 2. When working with other equipment, the fixing frame 1 can be installed on the corresponding equipment. For example, it is installed on a nailing and rolling machine, and works with the nailing and rolling machine to provide aluminum foil to the nailing and rolling machine, and the aluminum foil is wound into capacitor elements. In specific implementation, the sleeve 201 can be a bearing, and the bearing reduces the rotation resistance of the shaft 2 and also improves the stability. In some embodiments, multiple sleeves 201 can be placed at different positions in the shaft 2 to make the shaft 2 more firm and stable. A baffle 5 is provided in the shaft 2, and the baffle 5 plays the role of limiting and fixing the foil coiling disk 8.

[0022] The rotating shaft 2 can pass through the fixing frame 1, and a fixing mechanism 3 is arranged on the side of the rotating shaft 2 away from the fixing frame 1. The fixing mechanism 3 includes an expansion tube 301, an adjustment component 302, and a clamp 303. The adjustment component 302 is provided with a plurality of clamps 303, wherein one end of the clamp 303 is provided with an expansion tube 301.

[0023] The rotating shaft 2 penetrates and is fixed to the fixing mechanism 3; a foil coiling disc 8 is installed on the outer side of one end of the fixing mechanism 3, and the fixing mechanism 3 plays the role of fixing the foil coiling disc 8. More specifically, the fixing mechanism 3 is composed of an expansion tube 301, an adjustment component 302, and a clamping gripper 303, wherein the opening and closing of the expansion tube 301 is controlled by the adjustment component 302. The adjustment component 302 includes an adjustment rod 3021, a first gear 3022, and a second gear 3023, wherein the first gear 3022 and the second gear 3023 are both sleeved on the outer side of the rotating shaft 2, an adjustment rod 3021 is arranged on the outer periphery of the first gear 3022, the first gear 3022 is gear-engaged with the second gear 3023, and a plurality of clamping grippers 303 are arranged on the outer periphery of the second gear 3023. Specifically, the adjustment rod 3021 disposed outside the first gear 3022 is perpendicular to the outer wall of the first gear 3022. Under the action of external force, the first gear 3022 is rotated by rotating the adjustment rod 3021. The first gear 3022 and the second gear 3023 are both sleeved on the outer side of the rotating shaft 2, and the first gear 3022 is gear-engaged with the second gear 3023. When the external force pushes the adjustment rod 3021, the first gear 3022 rotates. Due to the gear-engaged relationship between the first gear 3022 and the second gear 3023, the second gear 3023 rotates with the first gear 3022. A plurality of grippers 303 are disposed on the outer periphery of the second gear 3023. When the second gear 3023 rotates, the grippers 303 on the outer periphery of the second gear 3023 are pushed to move away from or close to the axis of the second gear 3023.

[0024] Preferably, the expansion tube 301 includes a support wall 3011 and a fixing seat 3012 , each clamp 303 is fixedly connected to a corresponding support wall 3011 , and multiple support walls 3011 are arranged in a circular array around the rotating shaft 2 , and two adjacent support walls 3011 are closed or opened to form the expansion tube 301 .

[0025] Specifically, each end of the clamp 303 is fixedly connected to a support wall 3011, and the movement of the clamp 303 drives the support wall 3011 to move. Multiple support walls 3011 are arranged in a ring around the rotating shaft 2. When the clamp 303 drives the support wall 3011 to move outward, two adjacent support walls 3011 move away from each other to form an open state, that is, the expansion tube 301 is in a contracted state; when the clamp 303 drives the support wall 3011 to move inward, two adjacent support walls 3011 are close to each other and spliced ​​to form a closed state, that is, the expansion tube 301 is in an open state.

[0026] The outer wall of the expansion tube 301 in the rotating shaft 2 and the inner wall of the central through hole of the foil coiling disc 8 are pressed against each other, so that the foil coiling disc 8 is fixed in the expansion tube 301. Specifically, when the device is in operation, the foil coiling disc 8 is fixed on the rotating shaft 2, and the aluminum foil in the foil coiling disc 8 is connected to the nailing and rolling machine. The aluminum foil in the foil coiling disc 8 is driven to rotate around the rotating shaft 2 under the traction of the nailing and rolling machine, and the foil coiling disc 8 continuously supplies aluminum foil to the nailing and rolling machine.

[0027] A driving mechanism 4 for driving the rotating shaft 2 to rotate is arranged at one end of the rotating shaft 2 away from the fixing mechanism 3 ; a blocking component 6 is arranged on one side of the rotating shaft 2 on the fixing frame 1 .

[0028] Specifically, the power output end of the driving mechanism 4 is connected to one end of the rotating shaft 2. In this embodiment, the driving mechanism 4 is preferably a motor, and the driving mechanism 4 performs clockwise or counterclockwise rotation under the control command. The driving mechanism 4 drives the rotating shaft 2 to rotate, and the adjustment rod 3021 in the adjustment component 302 cooperates with the blocking component 6 to realize the opening and closing of the expansion tube 301.

[0029] A telescopic rod 601 is provided at one end of the blocking assembly 6, and when the telescopic rod 601 is extended, it can be engaged with the adjusting rod 3021 rotating around the axis of the rotating shaft 2. The adjusting rod 3021 is perpendicular to the first gear 3022 and connected to one side of the first gear 3022. The adjusting rod 3021 rotates with the rotating shaft 2 when the rotating shaft 2 rotates.

[0030] Specifically, the driving mechanism 4 drives the rotating shaft 2 to rotate, and the adjusting rod 3021 performs low-speed circular motion around the axis of the rotating shaft 2 driven by the rotating shaft 2. In the embodiment, a speed reduction mechanism is provided in the driving mechanism 4 to enable the rotating shaft 2 to rotate at a low speed, so as to prevent the adjusting rod 3021 from rotating too fast and violently colliding with the blocking assembly 6. In the specific operation, when the system detects that the foil coiling disk 8 needs to be replaced, the system sends a driving instruction to the driving mechanism 4 to drive the rotating shaft 2 to rotate, thereby driving the adjusting rod 3021 to perform low-speed circular motion around the axis of the rotating shaft 2. On the other hand, the system gives an instruction to the blocking assembly 6 to drive the telescopic rod 601 in the blocking assembly 6 to extend. In the present embodiment, the blocking assembly 6 is preferably a cylinder. The telescopic rod 601 extends out of the telescopic rod 601 under the push of the cylinder to clamp the adjusting rod 3021. When the adjusting rod 3021 is clamped by the telescopic rod 601, the adjusting rod 3021 will resist the reverse push, so that the first gear 3022 performs the opposite motion to the rotating shaft 2. The first gear 3022 drives the second gear 3023 to rotate, and when the second gear 3023 rotates, it drives the gripper 303 connected to the second gear 3023 to move away from the axis of the second gear 3023. The gripper 303 drives the support wall 3011 to move outward, so that each support wall 3011 squeezes the inner wall of the center hole of the foil coiling disc 8, so that the foil coiling disc 8 is stably installed in the expansion tube 301, and the foil coiling disc 8 is automatically fixed, and the installation of the foil coiling disc 8 is convenient, which improves the replacement efficiency of the foil coiling disc 8.

[0031] In some embodiments, a detection component 7 for detecting aluminum foil information is provided above the foil reel 8. The detection component 7 is used to detect the presence or absence of aluminum foil. When there is no aluminum foil in the foil reel 8 of the detection component 7, the system sends a command to the drive mechanism 4 to control the drive mechanism 4 to rotate counterclockwise, drive the rotating shaft 2 to rotate counterclockwise, and then drive the adjustment rod 3021 to perform low-speed circular motion around the axis of the rotating shaft 2. When the adjustment rod 3021 rotates to the blocking component 6 and is engaged with the telescopic rod 601, the adjustment rod 3021 will resist the reverse thrust, so that the first gear 3022 moves in the opposite direction to the rotating shaft 2. The first gear 3022 drives the second gear 3023 to rotate, and when the second gear 3023 rotates, it drives the catch 303 connected to the second gear 3023 to move close to the axis of the second gear 3023. The gripper 303 drives the support wall 3011 to move inward, so that each support wall 3011 is away from the inner wall of the center hole of the foil coiling disc 8, so that the foil coiling disc 8 falls off and is installed in the expansion tube 301, and the foil coiling disc 8 is automatically disassembled. The expansion tube 301 in the fixing mechanism 3 is controlled by the driving mechanism 3 to contract or open, so as to tighten and loosen the foil coiling disc 8, so as to achieve the effect of quickly replacing and installing the foil coil 8, solve the problem of complex and low efficiency of the traditional material replacement process, and improve the efficiency of replacing materials.

[0032] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive.

Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
