Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet production and processing equipment, and in particular to a high-precision, damage-free unwinding mechanism for silicon steel sheets. Background Technology

[0002] A brushless motor is a device that converts electrical energy into mechanical energy. A brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product. Brushless motors have advantages such as no brushes, low interference, low noise, and long life. The iron core of a brushless motor is usually formed by pressing oriented silicon steel sheets. During the production process, the silicon steel sheets usually need to be unwound by an unwinding mechanism. Existing unwinding machines usually do not have limit devices on the outside, and the coil is prone to skewing during the unwinding process. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this invention provides a high-precision, damage-free unwinding mechanism for silicon steel sheets.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-precision, damage-free unwinding mechanism for silicon steel sheets, including an expanding and contracting drum, four evenly distributed fan-shaped plates on the outer side of the expanding and contracting drum, a turntable on one side of the expanding and contracting drum, a driving mechanism on the side of the turntable away from the expanding and contracting drum, an inner baffle on the side of the fan-shaped plates near the turntable, and an outer baffle on the side of the expanding and contracting drum away from the inner baffle. The outer baffle includes a C-shaped clamping plate that fits with the fan-shaped plates, locking screws on both sides of the C-shaped clamping plate, a first pressure plate on the inner side of the fan-shaped plates and outside the locking screws, one side of the first pressure plate being in contact with the inner sidewall of the C-shaped clamping plate, and a stop bar rotatably connected to the middle position of the outer side of the C-shaped clamping plate. In use, the coil is put onto the outside of the expanding and contracting drum, the outer side of the expanding and contracting drum engages with the inner diameter of the coil, then the C-shaped clamping plate is put on, the locking screws on both sides are tightened, the first pressure plate moves up and locks with the inner sidewall of the fan-shaped plates.

[0005] Preferably, the inner baffle is fixedly connected to the sector plate by an adjusting member. The adjusting member includes an adjusting screw that passes through the inner baffle and the sector plate. A second pressure plate is connected to the end of the adjusting screw. A limiting slide groove is fixedly connected to the inner side of the sector plate. The second pressure plate is located in the limiting slide groove. An elongated groove is provided on the sector plate for the adjusting screw to move.

[0006] Preferably, a hydraulic cylinder is provided below the drive mechanism. The height of the expansion and contraction drum can be adjusted by the hydraulic cylinder to facilitate the mounting of the rolled material and to better adapt to the height required when unwinding different materials.

[0007] Preferably, the diameter of the stop bar is larger than the width of the C-shaped clamping plate to prevent the C-shaped clamping plate 7 from contacting the side wall of the coil and affecting the operation of the stop bar.

[0008] The beneficial effects of this utility model are that the outer wall of the coil is limited by the stop bar, preventing the coil from deviating during unwinding and effectively improving the unwinding accuracy. Furthermore, the unwinding of the coil drives the stop bar to rotate, effectively reducing wear on the coil. In addition, the inner stop is fixedly connected to the sector plate via an adjusting component. The sector plate has an elongated groove for the adjusting screw to move. The position of the inner stop can be appropriately adjusted by the combination of the adjusting component and the elongated groove, allowing coils of different widths to be aligned with the external equipment on the same central axis. The height of the expansion and contraction drum can be adjusted by a hydraulic cylinder, facilitating the loading of the coil and better adapting to the height required for unwinding different materials.

[0012] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0013] like Figure 1-4The diagram illustrates a high-precision, damage-free unwinding mechanism for silicon steel sheets, comprising an expanding and contracting drum 1. Four evenly distributed sector-shaped plates 2 are located on the outer side of the expanding and contracting drum 1. A turntable 3 is positioned on one side of the expanding and contracting drum 1, and a driving mechanism 4 is located on the side of the turntable 3 away from the expanding and contracting drum 1. An inner baffle 5 is positioned on the side of the sector-shaped plates 2 closest to the turntable 3, and an outer baffle 6 is positioned on the side of the expanding and contracting drum 1 away from the inner baffle 5. The outer baffle 6 includes a C-shaped clamping plate 7 that fits into the sector-shaped plates 2. The C-shaped clamping plate 7 is provided with locking screws 8 on both sides. The first pressure plate 9 is provided on the inner side of the fan-shaped plate 2 and the outer sleeve of the locking screws 8. One side of the first pressure plate 9 is in contact with the inner wall of the C-shaped clamping plate 7. A stop bar 10 is rotatably connected to the middle position of the outer side of the C-shaped clamping plate 7. When in use, the roll material is put on the outside of the expansion and contraction drum 1. The outer expansion and contraction drum engages with the inner diameter of the roll material. Then, the C-shaped clamping plate 7 is put on, and the locking screws 8 on both sides are tightened. The first pressure plate 9 moves up and locks with the inner wall of the fan-shaped plate 2.

[0014] The inner baffle 5 is fixedly connected to the sector plate 2 via an adjusting member 11. The adjusting member 11 includes an adjusting screw 12 that passes through the inner baffle 5 and the sector plate 2. A second pressure plate 13 is connected to the end of the adjusting screw 12. A limiting slide groove 14 is fixedly connected to the inner side of the sector plate 2. The second pressure plate 13 is located in the limiting slide groove 14. An elongated groove 15 is provided on the sector plate 2 for the adjusting screw 12 to move.

[0015] A hydraulic cylinder 16 is provided below the drive mechanism 4. The height of the expansion and contraction drum 1 is adjusted by the hydraulic cylinder 16 to facilitate the mounting of the rolled material and to better adapt to the height required when unwinding different materials.

[0016] The diameter of the stop bar 10 is larger than the width of the C-shaped clamp 7 to prevent the C-shaped clamp 7 from contacting the side wall of the coil and affecting the operation of the stop bar 10.

[0017] Working principle: The expansion and contraction drum 1 is adjusted to a suitable height by the hydraulic cylinder 16. The adjusting screw 12 is loosened, and the inner baffle 5 is adjusted to a suitable position according to the width of the roll material. The adjusting screw 12 is tightened. At this time, the roll material and the external equipment are on the same central axis. Then, the baffle 10 is set outside the fan-shaped plate 2 by the C-shaped clamping plate 7. The baffle 10 is pushed inward until it is in contact with the outer side of the roll material. The locking screws 8 on both sides are tightened, and the position of the C-shaped clamping plate 7 is fixed by the first pressure plate 9 to complete the limiting work.

[0018] This design is ingenious. A stop bar limits the outer wall of the coil material, preventing deviation during unwinding and effectively improving unwinding accuracy. Furthermore, the unwinding action causes the stop bar to rotate, mitigating wear. Additionally, the inner baffle is fixedly connected to a sector plate via an adjusting component. The sector plate has an elongated groove for adjusting the screw. The combination of the adjusting component and the groove allows for proper adjustment of the inner baffle's position, ensuring that coils of different widths are aligned with the external equipment on the same central axis. The height of the expansion and contraction drum is adjusted via a hydraulic cylinder, facilitating coil placement and better adapting to the height requirements of unwinding different materials.

[0019] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
