Description

Technical Field

[0001] This utility model relates to the field of aluminum foil slitting technology, specifically to an aluminum foil slitting mechanism. 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. Aluminum foil slitting involves efficiently and precisely cutting aluminum foil (wide rolls) into multiple narrow rolls of accurate size, neat edges, and perfect shape, according to customer requirements, with minimal or no waste.

[0003] Existing aluminum foil slitting mechanisms typically employ two cutting discs, one above the other, for slitting. However, with prolonged use or errors in position adjustment, the aluminum foil can easily become stuck between the two discs, making adjustment difficult. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum foil slitting mechanism to solve the problems mentioned in the background art.

A servo motor is provided on the upper surface of the support plate. The output shaft of the servo motor is connected to a lead screw through a coupling. The bottom end of the lead screw is rotatably connected to the lead screw seat. The lead screw cooperates with the lead screw nut pair on the corresponding side. A fixed roller is also rotatably disposed between the two side plates. A first connecting sleeve is coaxially provided on one side of the slitting disc, and the slitting disc is connected to the fixed roller through the first connecting sleeve and fastened with bolts.

A lead screw seat 8 is provided on the upper surface of the support plate 7. A support plate 9 is provided on the upper surface of the side plate 1 and located at the longitudinal guide groove 3. A servo motor 10 is provided on the upper surface of the support plate 9. The output shaft of the servo motor 10 is connected to a lead screw 11 through a coupling. The bottom end of the lead screw 11 is rotatably connected to the lead screw seat 8. The lead screw 11 is connected to the corresponding side plate 1. The screw and nut assembly 6 is engaged, and a fixed roller 12 is rotatably arranged between the two side plates 1. A synchronous motor 18 is arranged on the outer side of any side plate 1. The output shaft of the synchronous motor 18 is connected to one end of the fixed roller 12. The fixed roller 12 is driven to rotate by the synchronous motor 18. The synchronous motor 18 is used to ensure that it rotates synchronously with the winding motor of the winding equipment, so as to ensure that the aluminum foil will not break due to speed difference during slitting. A fixed plate 21 is arranged at the bottom of the side plate 1. Several second reinforcing plates 22 are arranged at the connection between the fixed plate 21 and the side plate 1. The fixed plate 21 is used to realize the fixed installation of the frame, and the second reinforcing plates 22 are used to ensure the stability of the frame. A first connecting sleeve 14 is coaxially arranged on one side of the slitting disc 13. The slitting disc 13 is connected to the fixed roller 12 through the first connecting sleeve 14 and is fastened by bolts. A second connecting sleeve 16 is coaxially provided on one side of the positioning disk 15. The positioning disk 15 is connected to the movable roller 4 through the second connecting sleeve 16 and is fastened by bolts. The positioning disk 15 has an annular positioning groove 17 along the circumferential direction. The slitting blade 13 corresponds to the positioning disk 15 one by one. The slitting blade 13 is inserted into the annular positioning groove 17 of the corresponding positioning disk 15. The support plate 9 is provided with first reinforcing plates 19 on both sides, and a connecting plate 20 is provided at the bottom of the first reinforcing plate 19. The support plate 9 is fastened to the top of the side plate 1 by bolts, and the connecting plate 20 is fastened to the side plate 1 by bolts. The first reinforcing plates 19 are used to ensure the structural strength of the support plate 9, and the connecting plate 20 is used to further improve the support of the support plate 9.

[0015] Installation method and working principle: During installation, first, the slitting disc 13 is fitted onto the fixed roller 12 through the first connecting sleeve 14. Then, the positioning disc 15 is fitted onto the movable roller 4 through the second connecting sleeve 16. The two ends of the movable roller 4 are connected to the slide block 5 through bearing seats. When installing the frame, first, the slide block 5 is placed in the longitudinal guide groove 3. Then, the two ends of the fixed roller 12 are connected to the side plate 1 through bearing seats. Subsequently, the two side plates 1 are connected by multiple connecting beams 2. The support plate 9 is installed on the top of the side plate 1 with bolts, and the connecting plate 20 is connected to the side plate 1 with bolts to reinforce the support plate 9. Then, the lead screw 11 is passed through the support plate 9 and connected to the lead screw nut pair 6 at the outer end of the slide block 5. Next, the bottom end of the lead screw 11 is connected to the lead screw seat 8. Finally, the servo motor 10 is installed on the upper surface of the support plate 9, and the output shaft of the servo motor 10 is connected to the top of the lead screw 11 through a coupling to complete the installation. When adjusting the slitting disc 13 and the positioning disc 15, tighten the bolts used to fix the first connecting sleeve 14 and loosen the bolts used to fix the second connecting sleeve 16 of the plate. The two servo motors 10 rotate synchronously, and through their cooperation with the lead screw and nut pair 6, drive the two side slides 5 to descend synchronously, causing the slitting disc 13 to insert into the annular positioning groove 17 of the positioning disc 15 at the corresponding position. Then, tighten the bolts used to fix the second connecting sleeve 16 of the plate, completing the positioning and fixing of the slitting disc 13 and the positioning disc 15. During operation, the movable roller 4 rises, causing the slitting disc 13 to disengage from the positioning disc 15. The aluminum foil is supported on the slitting disc 13. The two servo motors 10 rotate synchronously, driving the two side slides 5 to descend synchronously, causing the blade of the slitting disc 13 to insert into the annular positioning groove 17 of the positioning disc 15 at the corresponding position, completing the slitting of the aluminum foil. During this process, the aluminum foil is wound and pulled by the winding mechanism at the rear station. This utility model has a reasonable structure. A number of slitting discs 13 are fixedly arranged on the upper part, and a number of positioning discs 15 are arranged on the movable roller 4. The positioning discs 15 cooperate with the slitting discs 13 through annular positioning grooves 17, thereby improving the slitting effect of the aluminum foil. The slitting discs 13 are securely connected to the fixed roller 12 through a first connecting sleeve 14 and bolts, and the positioning discs 15 are securely connected to the movable roller 4 through a second connecting sleeve 16 and bolts. This structure allows for adjustment of the positions of the slitting discs 13 and positioning discs 15 according to requirements, ensuring applicability and flexibility. It also facilitates adjustment of the position of the positioning discs 15, ensuring a perfect match between the positioning discs 15 and the corresponding slitting discs 13. Compared to the traditional upper and lower double-disc structure, this avoids paper jams.
