Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil processing equipment, and in particular to a winding shaft connecting device for an aluminum foil slitting machine. Background Technology

[0002] In the aluminum foil production and processing process, slitting machines are one of the commonly used pieces of equipment. They are mainly used to cut wide aluminum foil into narrow aluminum foil of the required width.

[0003] Currently, the connection between the winding shaft and the drive side of the slitting machine is mostly a fixed connection. When it is necessary to replace the winding shaft with a different specification or to perform maintenance on the winding shaft, the disassembly and assembly process is cumbersome, and the fixed connection is prone to breakage, seriously affecting production efficiency. In addition, some connection devices use winding shafts with fixed specifications, which are difficult to adapt to core materials with different inner diameters, resulting in poor applicability. Moreover, after long-term use, the connection is prone to loosening, causing problems such as misalignment and inconsistent tension of the wound aluminum foil, affecting the product quality of the aluminum foil. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a solution to the problems of cumbersome disassembly and assembly processes and the high risk of breakage in the existing connection method between the winding shaft and the drive side of the slitting machine, which seriously affects production efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A winding shaft connecting device for an aluminum foil slitting machine includes a large conical head and a winding shaft. A core material is sleeved on the winding shaft. Two large conical heads are provided and are respectively installed on the drive side of the slitting machine. The winding shaft is positioned between the opposing surfaces of the two large conical heads. Small conical heads are respectively installed at both ends of the winding shaft via transmission components. Pins are evenly distributed on the outer surface of the small conical heads. Insertion holes are provided on the side of the large conical heads corresponding to the positions of the pins. The pins are fitted into the insertion holes, and the small conical heads and the large conical heads are detachably connected through the engagement of the pins and the insertion holes.

[0007] The winding shaft is an air-expanding shaft.

[0008] Both ends of the winding shaft are connected to the transmission components via connecting shafts.

[0009] The transmission component includes an internal gear and an external gear. The external gear is mounted on the shaft end of the connecting shaft, and the internal gear is coaxially disposed on the inner side of the small cone. The external gear meshes with the internal gear.

[0010] A spring is fitted onto the connecting shaft.

[0011] The spring is in a contracted state.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets a pin on the small cone and a hole on the large cone, and uses the cooperation of the pin and the hole to realize the detachable connection between the small cone and the large cone, thereby realizing the quick assembly and disassembly of the winding shaft and the drive side of the slitting machine, which greatly shortens the time for replacing the winding shaft or maintaining it, and improves work efficiency.

[0013] The winding shaft is an air-expanding shaft, which can change its outer diameter by inflating and deflating air, making it suitable for core materials with different inner diameters. This significantly improves the applicability of the device. At the same time, it can effectively tighten the core material, ensuring the stability of the core material during the winding process, avoiding problems such as deviation during aluminum foil winding, and improving the winding quality of aluminum foil.

[0014] The transmission components use an internal and external gear meshing connection, coupled with a spring in a contracted state, which can ensure the stability and reliability of the transmission, reduce the impact of vibration on the transmission, avoid failures such as tooth slippage, and extend the service life of the device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] A winding shaft connection device for an aluminum foil slitting machine includes a large conical head 4 and a winding shaft 3. A core material is sleeved on the winding shaft 3. Two large conical heads 4 are provided, each installed on the drive side of the slitting machine. The winding shaft 3 is positioned between the opposing surfaces of the two large conical heads 4. Small conical heads 6 are installed at both ends of the winding shaft 3 via transmission components. Pins 5 are evenly distributed on the outer surface of the small conical heads 6. Insertion holes are provided on the side of the large conical heads 4 corresponding to the positions of the pins 5. The pins 5 are fitted into the insertion holes. The engagement of the pins 5 and the insertion holes allows for a detachable connection between the small conical heads 6 and the large conical heads 4, enabling quick assembly and disassembly of the winding shaft 3 from the drive side of the slitting machine. This significantly reduces the time required for replacing or maintaining the winding shaft 3, improving work efficiency.

[0022] The winding shaft 3 is an air-expanding shaft, which can change its outer diameter by inflating and deflating air, and can adapt to core materials with different inner diameters, significantly improving the applicability of the device. At the same time, it can effectively tighten the core material, ensure the stability of the core material during the winding process, avoid problems such as deviation during aluminum foil winding, and improve the winding quality of aluminum foil.

[0023] Both ends of the winding shaft 3 are connected to the transmission components via connecting shafts.

[0024] The transmission component includes an internal gear 7 and an external gear 2. The external gear 2 is mounted on the shaft end of the connecting shaft, and the internal gear 7 is coaxially disposed on the inner side of the small cone head 6. The external gear 2 is meshed with the internal gear 7.

[0025] A spring 8 is fitted on the connecting shaft. The spring 8 is in a contracted state. The spring 8 can absorb vibration and impact energy during operation, store energy, and release it when needed. It also has the function of resisting and buffering pressure.

[0026] During use, align the pins 5 on the small cones 6 at both ends of the winding shaft 3 with the insertion holes on the large cone 4, and then insert the pins 5 into the insertion holes. At this time, the external gear 2 and the internal gear 7 mesh, and the spring 8 is in a contracted state, applying preload to the connecting shaft to ensure a stable connection of all components. Based on the inner diameter of the core material used, inflate the air shaft through the air nozzle 1 on the side of the air shaft to tighten the core material. The power from the drive side of the slitting machine is transmitted to the winding shaft 3 through the large cone 4, small cone 6, internal gear 7, external gear 2, and connecting shaft, causing the winding shaft 3 to rotate and thus winding the aluminum foil. When it is necessary to disassemble the winding shaft 3, first release the air from the air shaft, and then pull the pins 5 out of the insertion holes. The operation is simple and convenient.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
