Description

Technical Field

[0001] The utility model relates to the technical field of industrial production, in particular to a device for preventing wrinkles and shaking of a large-diameter roll when winding. Background Art

[0002] The general winding diameter of the winding material is about 800mm. With the development of equipment requirements, more and more customers require the winding diameter to be around 1200mm. As the winding diameter increases, the reserved space for winding will also increase, and the distance between the roller and the center of the reel will also increase accordingly. The distance between the pole piece and the drum after passing through the roller increases. As the speed increases, the pole piece will have corresponding jitter, resulting in wrinkles, stirrups, and uneven winding of the pole piece during the winding process. If a close roller winding mechanism is used, the close roller will move with the change of the winding diameter, effectively avoiding the phenomena of wrinkles, stirrups, and uneven winding.

[0035] The following is a further explanation of this patent through the working conditions of this patent:

[0036] Reference Figure 1 and Figure 2 A device for preventing wrinkles and shaking of large-diameter rolls of material to be wound up includes an approach roller assembly, a chain transmission assembly, and a roll pressure roller assembly.

[0037] The approach roller assembly functions to ensure that the approach roller retracts as the winding diameter increases. This eliminates pole piece jitter and allows the delivered pole piece to be wound directly onto the winding shaft, preventing wrinkles and entanglement. The entire approach roller assembly is secured to the side plate 11 via a slider 6 and a guide rail 7. The approach roller assembly slides back and forth on the guide rail 7 via the slider 6. This sliding motion is driven by a servo motor 12 and a speed reducer 13, which rotate a shaft 14. Gears 5 are fixed to either side of the shaft 14. The rotation of the gears 5 drives the movement of the rack 4, which is secured to the sliding plate 3, thereby driving the entire approach roller assembly back and forth.

[0038] The movement of the approach roller assembly is controlled by a pair of through-beam sensors. When the through-beam sensor 16 detects the edge of the material roll 15, it will feed back the signal to the servo motor 12 to control the movement of the approach roller assembly. As the diameter of the pole piece wound on the material roll 15 becomes larger and larger, the through-beam sensor 16 has been detecting the edge, and the approach roller will retreat farther and farther as the diameter of the material roll increases, but the approach rubber roller 1 is always pressed against the material roll 15, ensuring that the winding of the winding pole piece is not like the previous phenomenon of pole piece jitter, material roll stirrups, wrinkles, etc. caused by the long distance between the roller and the winding material roll.

[0039] The extension of the proximity roller 1 is driven by the cylinder 2, and the stroke of the cylinder 2 is selected according to the specific actual size. The position of the proximity roller assembly is detected by the proximity switch 9. There are three proximity switches 9 in total, which control the front limit position, the rear limit position, and the working position respectively.

[0040] Considering the safety of the sensor, mechanical limits are also provided. There is a rear limit block 10 at the rear of the approach roller assembly and a front limit block 17 at the front to serve as hard limits, so that the motor will not drive the entire approach roller assembly off the guide rail.

[0041] The chain transmission assembly comprises a chain 8, a threading rod 19 and a plurality of sprockets 18. Since the equipment is relatively high and manual threading is inconvenient, a chain assembly is specially designed to facilitate threading. The pole piece is attached to the threading rod 19 and the hand wheel 20 is cranked. The threading rod will drive the pole piece to automatically thread the pole piece according to the designed chain route. Since the chain needs to be threaded onto the approach roller assembly, the approach roller is movable back and forth. In order to ensure that the chain does not affect the forward and backward movement of the approach roller after being threaded, the chain on the approach roller and the chain on the side plate must be kept parallel to each other.

[0042] The pressure roller assembly prevents uneven winding caused by loosening of the electrode sheets wound on the take-up shaft. The pressure roller assembly uses a cylinder 21 to drive a swing arm 22 and a pressure roller 23 at the end of the swing arm to press the electrode sheets against the take-up shaft 15. The cylinder 21 is always in a taut state, keeping the pressure roller pressed against the take-up shaft 15. The cylinder 21 is controlled by an electric proportional valve with automatic feedback, which automatically adjusts the pressure of the pressure roller on the barrel.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
