Description

Technical Field

[0001] The present application relates to the technical field of amorphous strip processing, and in particular to an amorphous strip unwinding device. Background Art

[0002] The main function of the unwinding device is to provide stable and continuous amorphous strip for subsequent processing. It needs to have the functions of unwinding, tensioning the strip, and coating the insulation layer when necessary to ensure that the strip maintains proper tension and position during the winding process to prevent the strip from wrinkling or deflecting.

[0003] Amorphous strips need to be unwound from an unwinding drum during the production process. However, due to the relatively smooth surface of the amorphous strips, they are prone to deviation on the unwinding drum during the unwinding process, which will affect the subsequent processing of the amorphous strips and reduce the stability of the unwinding of the amorphous strips.

[0004] Application Contents In order to solve the above-mentioned defects, the present application provides an amorphous strip unwinding device.

[0005] The present application provides an amorphous strip unwinding device using the following technical solutions: An amorphous strip unwinding device comprises an unwinding frame, an unwinding shaft is rotatably connected to the unwinding frame, a driving member for driving the unwinding shaft to rotate is arranged on the unwinding frame, an unwinding drum is slidably matched with the unwinding shaft, an adjusting component for adjusting the position of the unwinding drum is arranged on the unwinding shaft, a clamping component is arranged on the unwinding drum, the clamping component comprises a clamping arc block, a locking block and an ejection spring, a clamping notch is arranged on the unwinding drum, the clamping arc block is rotatably connected in the clamping notch, and an installation groove and A toggle groove, the locking block is slidably fitted in the installation groove, the locking block is provided with an interference slope and a toggle rod, the toggle rod is slidably fitted in the toggle groove, the ejection spring is arranged in the installation groove, and is located between the locking block and the inner end wall of the installation groove, and a locking groove is provided on the side wall of the clamping notch. During installation, one end of the amorphous strip is located between the clamping arc block and the clamping notch, the locking block is inserted into the locking groove, and an unlocking component for loosening the clamping arc block is provided on the unwinding drum.

[0006] By adopting the above technical solution, during installation, one end of the amorphous strip is placed into the clamping notch, and then the clamping arc block is closed. During this process, the contacting inclined surface contacts the side of the clamping notch and moves, and the ejection spring is compressed until the installation groove is aligned with the locking groove. The locking block is moved by the force of the ejection spring and inserted into the locking groove, so as to install the amorphous strip. Then, the unwinding drum is adjusted to an appropriate position on the unwinding shaft by using the adjustment component, and the preparation work before unwinding the amorphous strip is completed. By using the clamping component to limit one end of the amorphous strip, the possibility of slipping during the unwinding rotation of the amorphous strip is reduced, and the amorphous strip is kept in one position as much as possible for unwinding, so that the amorphous strip can be unwound better, the unwinding stability of the amorphous strip is improved, and the subsequent amorphous strip processing steps are also facilitated to be better carried out.

[0007] Optionally, a friction pad is installed on the inner arc wall of the clamping notch, and one end of the amorphous strip is located between the friction pad and the clamping arc block.

[0008] By adopting the above technical solution, the friction pad is used to increase the friction between the amorphous strip and the clamping notch, which further reduces the possibility of sliding deviation when the amorphous strip rotates.

When unlocking, the top block pushes the locking block.

[0010] By adopting the above technical solution, when unlocking the compression arc block, pressure is applied to the pressing rod to drive the top block to move, the return spring is compressed, and the top block pushes the locking block to move until the locking block is disengaged from the locking groove. At this time, the compression arc block can be opened, achieving the effect of unlocking the compression arc block.

[0012] By adopting the above technical solution, when adjusting the position of the unwinding drum, the adjusting screw is rotated to move the nut block, thereby driving the unwinding drum to move, thereby achieving the effect of adjusting the position of the unwinding drum.

[0013] Optionally, a clamping assembly is provided on the unwinding frame, and the clamping assembly includes a clamping roller, a rotating frame, a first counterweight block and a second counterweight block. The unwinding frame is connected to a fixed frame, and the rotating frame is connected to an adjusting rod. An adjusting cylinder is sleeved on the adjusting rod, and the adjusting cylinder is connected to a rotating rod. An avoidance groove is provided on the rotating frame, and the rotating rod passes through the avoidance groove and is rotatably connected to the fixed frame. The first counterweight block is connected to one end of the rotating frame, and the other end of the rotating frame is rotatably connected to a clamping frame. The clamping roller is rotatably connected to the clamping frame and clamps against the surface of the amorphous strip, and the second counterweight block is connected to the clamping frame. A fine-tuning assembly for fine-tuning the torque of the rotating frame is provided on the adjusting rod.

[0014] By adopting the above technical solution, when the amorphous strip is pressed, the second counterweight is used to drive the pressing roller to apply pressure to the amorphous strip, and the first counterweight is used to apply pressure to one end of the rotating frame, thereby reducing the pressure of the second counterweight and the pressing roller on the amorphous strip, and the fine-tuning component is used to adjust the torque of the first counterweight and the pressing frame to adjust the actual pressing force on the amorphous strip. The torque of the first counterweight and the pressing frame is adjusted by the fine-tuning component to adjust the pressing force on the amorphous strip, so that the amorphous strip is not only kept in a tight state when unwinding, but also can rotate smoothly, so that the amorphous strip can be unwound better, and the unwinding stability of the amorphous strip is improved.

[0015] Optionally, the fine-tuning assembly includes a rotating ring and a limiting block, the limiting block is connected to the inner wall of the adjusting cylinder, the adjusting rod is provided with a limiting groove at a position corresponding to the limiting block, the limiting block is slidingly fitted in the limiting groove, and the rotating ring is rotatably connected to the adjusting cylinder and is threadedly fitted with the adjusting rod.

[0016] By adopting the above technical solution, when fine-tuning the torque of the rotating frame, the rotating ring is rotated to move the adjusting rod, thereby driving the rotating frame to move, thereby adjusting the torque of the first counterweight block and the clamping frame, thereby achieving the effect of fine-tuning the clamping force of the amorphous strip.

[0017] Optionally, a limiting assembly is provided on the unwinding frame, and the limiting assembly includes a limiting frame, a bidirectional screw, a limiting plate and a limiting rod. The limiting frame is connected to the unwinding frame, and the bidirectional screw is rotatably connected to the limiting frame. The limiting rod is connected to the limiting frame and is parallel to the bidirectional screw. Two limiting plates are provided between the bidirectional screw and the limiting rod. The limiting plates are threadably matched with the bidirectional screw and slidably matched with the limiting rod. When limiting, the amorphous strip is located between the two limiting plates.

[0018] By adopting the above technical solution, when limiting the amorphous strip, the bidirectional screw is rotated. Due to the cooperation of the limit plate and the limit rod, the two limit plates move toward the center position of the bidirectional screw at the same time until they hit the side of the amorphous strip, so that the amorphous strip is limited between the two limit plates, thereby limiting the unwinding position of the amorphous strip, allowing the amorphous strip to be unwound better, and stabilizing the discharge for the subsequent amorphous strip processing steps.

[0019] Optionally, the bidirectional screw is located between the limiting rod and the bottom wall of the limiting frame, the limiting rod is connected to a resistance roller, and the amorphous strip is placed on the resistance roller.

[0020] By adopting the above technical solution, when the amorphous strip is unwound, in order to avoid the amorphous strip being stretched and deformed in size, which affects the transportation and processing of the subsequent processes, the amorphous strip is in a relaxed state when unwound, but the amorphous strip will fall due to gravity. In order to unwind better, it is necessary to increase the angle of the amorphous strip when unwinding. By setting a contact roller, the amorphous strip is placed on the contact roller, so that the amorphous strip forms a certain unwinding angle, so that the amorphous strip can be unwound better.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. During installation, place one end of the amorphous strip into the clamping notch, and then close the clamping arc block. During this process, the inclined surface contacts the side of the clamping notch and moves, and the ejection spring is compressed until the installation slot is aligned with the locking slot. The locking block moves under the force of the ejection spring and is inserted into the locking slot to install the amorphous strip. Then, the adjustment assembly is used to adjust the unwinding drum to the appropriate position on the unwinding shaft, thus completing the preparation work before unwinding the amorphous strip. Using the clamping assembly to limit one end of the amorphous strip reduces the possibility of slippage during the unwinding rotation of the amorphous strip, and keeps the amorphous strip in one position as much as possible while unwinding. This allows the amorphous strip to be unwound better, improves the unwinding stability of the amorphous strip, and facilitates the subsequent amorphous strip processing steps to be better carried out; 2. When tightening the amorphous strip, use the second counterweight to drive the tightening roller to apply pressure to the amorphous strip, and use the first counterweight to apply pressure to one end of the rotating frame to reduce the pressure of the second counterweight and the tightening roller on the amorphous strip, and use the fine-tuning component to adjust the torque of the first counterweight and the tightening frame to adjust the actual tightening force on the amorphous strip. The torque of the first counterweight and the tightening frame is adjusted by the fine-tuning component to adjust the tightening force on the amorphous strip, so that the amorphous strip is not only kept in a tight state when unwinding, but also can rotate smoothly, so that the amorphous strip can be unwound better, and the unwinding stability of the amorphous strip is improved.

This allows the amorphous strip to be unwound better, improves the unwinding stability of the amorphous strip, and facilitates the subsequent amorphous strip processing steps to be better carried out.
