Description
Technical Field
[0001] This utility model relates to the technical field of feeding equipment for high-speed aluminum foil roll machines, specifically an unwinding mechanism for a high-speed aluminum foil roll rewinding machine. Background Technology
[0002] A hot stamping material made by directly rolling aluminum into thin sheets produces a stamping effect similar to that of pure silver foil, hence it is also called imitation silver foil. Because aluminum is soft, malleable, and has a silvery-white luster, the rolled sheets can be laminated onto offset paper with substances such as sodium silicate to create aluminum foil sheets, which can then be printed on.
[0003] Finished aluminum foil rolls are typically wound using a high-speed winding machine. The large aluminum foil roll is placed on the feeding mechanism of the high-speed winding machine; one end is unwound by the feeding mechanism, while the other end is wound and cut by the winding roller to obtain the finished aluminum foil roll. However, in existing feeding mechanisms, when the position of the large aluminum foil roll on the unwinding roller shifts, manual fine-tuning of the roll's position is required. This method is inconvenient, therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

[0022] Please see Figure 1-5 This utility model provides a technical solution: an unwinding mechanism for a high-speed aluminum foil roll rewinding machine, comprising a frame, an adjustment component and a feeding component;
[0023] The frame includes a first side plate 1, a second side plate 2 and a connecting rod 3. The first side plate 1 and the second side plate 2 are arranged in parallel and connected to each other by several connecting rods 3. A U-shaped groove 4 is provided on the upper part of one end of the first side plate 1 and the second side plate 2. A bracket 5 is provided on the outer surface of the second side plate 2 and located at the U-shaped groove 4. A motor 6 is provided on the outer side of the bracket 5. A drive gear 7 is provided on the output shaft of the motor 6.
[0024] The adjustment assembly includes a support rod 8, an adjustment block 9, and a locking screw 10. The support rod 8 is vertically arranged on the outer surface of the first side plate 1 and located at the corresponding U-shaped groove 4. The adjustment block 9 is sleeved on the support rod 8 and slides in cooperation with the support rod 8. The adjustment block 9 is provided with a locking screw 10, which is fastened to the support rod 8. A knob 19 is provided at the outer end of the locking screw 10, which is turned to facilitate the rotation of the locking screw 10. The adjustment block 9 has a limit groove 11.
[0025] The feeding assembly includes an unwinding roller 12, a support sleeve 13, a limiting plate 14, and a driven sleeve 15. Support sleeves 13 are fitted at both ends of the unwinding roller 12, and the two ends of the unwinding roller 12 are supported by the support sleeves 13 within the U-shaped grooves 4 of the first side plate 1 and the second side plate 2. Bearings are installed inside the support sleeves 13, and the bearings slide against the unwinding roller 12. A groove 18 is formed along the circumferential direction on the support sleeve 13, and the support sleeve 13 is limited to the U-shaped grooves 4 of the first side plate 1 and the second side plate 2 through the groove 18. With this structure, when making fine adjustments to the unwinding roller 12 left and right, the unwinding roller 12 and the support sleeve 15 can be positioned correctly. The sleeve 13 and the bearing are relatively displaced. One end of the unwinding roller 12 away from the motor 6 is provided with a limit plate 14. The outer side of the limit plate 14 cooperates with the limit groove 11 of the adjusting block 9. The unwinding roller 12 near the motor 6 is provided with a driven sleeve 15. The end of the driven sleeve 15 away from the limit plate 14 is open and the inner wall is provided with a toothed groove 16. The toothed groove 16 of the driven sleeve 15 cooperates with the driving gear 7. The side wall of the driven sleeve 15 is provided with a locking bolt 17. The locking bolt 17 is fastened to the driving gear 7. Through the cooperation of the locking bolt 17, the driven sleeve 15 and the driving gear 7 can be fastened together.
[0026] Usage and Principle: Aluminum foil is wound onto the unwinding roller 12. The support sleeves 13 at both ends of the unwinding roller 12 are then supported in the U-shaped grooves of the first side plate 1 and the second side plate 2, respectively. Simultaneously, the limiting disc 14 at one end of the unwinding roller 12 is engaged into the slot 18 of the adjusting block 9. Next, the position of the adjusting block 9 is controlled so that the driven sleeve 15 at the other end of the unwinding roller 12 engages with the drive gear 7 on the output shaft of the motor 6. Then, the position of the unwinding roller 12 is fine-tuned using the adjusting block 9 according to the position of the aluminum foil roll. During this process, the drive gear 7 moves relative to the driven sleeve 15. After determining the position, the locking bolt 17 is rotated. The friction between the locking bolt 17 and the drive gear 7 prevents the driven sleeve 15 from disengaging from the drive gear 7. The motor 6 is then started. The motor 6 drives the driven sleeve 15 to rotate via the drive gear 7, thereby rotating the unwinding roller 12 to achieve the unwinding of the aluminum foil. Before unwinding, the position of the roller can be fine-tuned using the adjusting block 9 to accommodate subsequent processes. This utility model has a reasonable structure. A support rod 8 is vertically arranged on the outer side of the first side plate 1. An adjusting block 9 is sleeved on the support rod 8. A limit plate 14 is provided at one end of the unwinding roller 12 located on the adjusting block 9. The limit plate 14 and the limiting groove 11 of the adjusting block 9 cooperate with each other. A driven sleeve 15 with a toothed groove 16 is provided at the end of the unwinding roller 12 away from the limit plate 14. The driven sleeve 15 cooperates with the driving gear 7 on the output shaft of the motor 6 and is fastened by the locking bolt 17. The limit plate 14 can be moved by the adjusting block 9, thereby realizing the fine adjustment of the unwinding roller 12, which greatly improves the flexibility and convenience.
