The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0051] like Figure 1-7 As shown, a novel slitting and rewinding machine includes a frame assembly 1, a rewinding assembly 2, a slitting assembly 3, and a hot-pressing assembly 4. The frame assembly 1 includes a base frame 11, a wall panel 12, a front transition roller 13, a rear transition roller 14, and a guide roller 15.

[0052] The two ends of the base frame 11 are respectively fixedly connected to the wall panel 12;

[0053] The two ends of the front transition roller 13 and the rear transition roller 14 are respectively connected to the wall panel 12;

[0054] The two ends of the guide roller 15 are connected to the wall panel 12 through tension sensors 5, and the guide roller 15 is located below the rear transition roller 14 on the side away from the front transition roller 13.

[0055] The rewinding assembly 2 is located between the front transition roller 13 and the base frame 11. The rewinding assembly 2 includes a frame 21, an air shaft 22, a cylinder 23 and a magnetic powder clutch 24.

[0056] A correction mechanism 6 is provided between the frame 21 and the base frame 11, and a coaxial cylinder 23 and a magnetic powder clutch 24 are provided on the left and right sides of the frame 21.

[0057] The two ends of the air shaft 22 are detachably connected to the cylinder 23 and the magnetic powder clutch 24 via a transmission assembly, respectively.

[0058] The hot-welding assembly 4 is located above the front transition roller 13 and the rear transition roller 14;

[0059] The slitting assembly 3 is located on the side of the guide roller 15 away from the rear transition roller 14.

[0060] In this embodiment, the heat-sealing assembly 4 is used to join the end of the previous adhesive film roll 100 with the beginning of the next adhesive film roll 100; the slitting assembly 3 is used to cut the rolled adhesive film into multiple adhesive films of different widths; and the deviation correction mechanism 6 is used to prevent the adhesive film roll 100 from deviating during transport.

[0061] Working principle: The film roll 100 with the air expansion shaft 22 is placed in the rewinding station, so that both ends of the air expansion shaft 22 are connected to the cylinder 23 and the magnetic powder clutch 24 respectively through the transmission assembly; the cylinder 23 drives the driven end to clamp the air expansion shaft 22, and the constant tension of rewinding is controlled by the magnetic powder clutch 24 at the drive end in conjunction with the tension sensor 5.

[0062] After the air shaft 22 is installed, the end of the film roll 100 is sequentially wound around the front transition roller 13, the rear transition roller 14 and the guide roller 15 and then connected to the winding machine via the slitting assembly 3; then the slitting assembly 3 is adjusted according to the requirements. During the process, the film roll 100 can obtain the required width of film after passing through the slitting assembly 3. The formed film is then wound into a film by the winding machine.

[0063] During the process, the film roll 100 is corrected along the edge by the correction mechanism 6 to prevent the film roll 100 from deviating during transmission.

[0064] During the process, the hot-welding component 4 is used to combine the end of the previous adhesive film roll 100 with the beginning of the next adhesive film roll 100, thereby achieving rapid combination of different adhesive film rolls 100 and improving the efficiency of slitting and rewinding.

[0065] The above structure enables automatic rewinding, correction, heat sealing, and slitting of EVA, co-extruded PO, and other adhesive films, with efficient, stable, and reliable operation.

[0066] Furthermore, such as Figure 1-7 As shown, the correction mechanism 6 includes a linear guide rail 61, a correction driver 62, and a correction sensor 63;

[0067] The correction sensor 63 is located on the outer side of one end of the front transition roller 13 and is fixedly connected to the wall plate 12;

[0068] The frame 21 is slidably connected to the base frame 11 via a linear guide rail 61;

[0069] The correction driver 62 is located between the frame 21 and the base frame 11. The correction driver 62 is fixedly connected to the base frame 11, and the driving end is connected to the frame 21.

[0070] In this embodiment, the distance of the film roll 100 passing the front transition roller 13 is monitored in real time by the correction sensor 63. When the monitored distance exceeds the set range, the correction driver 62 is triggered to drive the frame 21 to move, thereby correcting the deviation in real time during the unwinding process of the film roll 100 and effectively preventing the problem of unwinding deviation.

[0071] Furthermore, such as Figure 1-7 As shown, the hot-spinning assembly 4 includes a bracket 41, a heating strip 42, a pressure driver 43, a lifting plate 44, and a pressure plate 45;

[0072] The bracket 41 is connected to the two wall panels 12, and at least two downward actuators 43 are provided above the bracket 41;

[0073] The lifting plate 44 is slidably connected to the bracket 41 via a slide rail pair. The upper part of the lifting plate 44 is connected to the driving end of the pressure driver 43, and the lower part is connected to the heating strip 42.

[0074] The pressure plate 45 is located directly below the heating strip 42 and is connected to the bracket 41.

[0075] In this embodiment, the end of the film roll 100 passes between the heating strip 42 and the pressure plate 45 after passing around the front transition roller 13. When the end of the previous roll is placed above the support plate, and the material is fed and the front end of the next roll is aligned with the end of the previous roll, the pressure driver 43 is controlled to drive the heating strip 42 to press down and heat it, thereby enabling the bonding of multiple rolls of film.

[0076] Furthermore, such as Figure 1-7 As shown, in order to press the front end of the next roll tightly against the end of the previous roll before joining, to prevent displacement or shifting, and to improve the reliability and quality of the joining, a pre-pressing mechanism 7 is provided around the outer perimeter of the heating strip 42.

[0077] The pre-compression mechanism 7 includes a pre-compression plate 71, a telescopic rod 72, and an elastic element 73;

[0078] The pre-pressing plate 71 is located between the heating strip 42 and the pressure plate 45, and is slidably sleeved with the heating strip 42. Both ends of the pre-pressing plate 71 are connected to the lifting plate 44 via telescopic rods 72. The lower end face of the pre-pressing plate 71

[0079] The telescopic rod 72 is hidden inside the lifting plate 44, and the telescopic section passes through the lifting plate 44 and is connected to the pre-pressing plate 71.

[0080] The elastic element 73 is sleeved on the lifting section of the telescopic rod 72, and its two ends abut against the lifting plate 44 and the pre-pressing plate 71, respectively.

[0081] Furthermore, such as Figure 1-7 As shown, the slitting assembly 3 includes a blade holder 31, a discharge roller 32, and several cutters 33;

[0082] The two ends of the blade holder 31 and the discharge roller 32 are respectively connected to the wall plate 12. The blade holder 31 is located above the discharge roller 32, and the blade holder 31 is provided with a plurality of cutting blades 33 with their blades closely close to the discharge roller 32.

[0083] The cutter 33 is detachably connected to the cutter holder 31.

[0084] In this embodiment, the end of the film roll 100 passes through the cutter 33 and the discharge roller 32 after passing through the guide roller 15; during the passage, due to the arrangement of the cutter 33 and the discharge roller 32, the film roll 100 is cut as it passes through, thereby obtaining the required width of film.

[0085] In this implementation, the number and position of the cutters 33 are determined according to the required film width and quantity.

[0086] Furthermore, such as Figure 1-7 As shown, in order to achieve a stable and reliable transmission connection between the magnetic powder clutch 24 and the air expansion shaft 22, the transmission assembly includes a first transmission mechanism 8 connected to the magnetic powder clutch 24 and a second transmission mechanism 9 connected to the electric cylinder.

[0087] The first transmission mechanism 8 includes a first bearing 81 and a first connecting shaft 82;

[0088] The first connecting shaft 82 is mounted in the first bearing seat 81 via a bearing. The inner end of the first connecting shaft 82 is detachably connected to the air expansion shaft 22, and the outer end is connected to the transmission end of the magnetic powder clutch 24.

[0089] The first bearing 81 is fixedly connected to the frame 21;

[0090] The magnetic powder clutch 24 is fixedly connected to the first shaft seat 81.

[0091] Furthermore, such as Figure 1-7 As shown, the second transmission mechanism 9 includes a bushing 91, a second bearing 92, and a second connecting shaft 93;

[0092] The second bearing seat 92 is slidably sleeved inside the bearing sleeve 91;

[0093] The second connecting shaft 93 is mounted in the second bearing 92 via a bearing, and its inner end is detachably connected to the air expansion shaft 22;

[0094] The bushing 91 is fixedly connected to the frame 21, and the outer side of the bushing 91 is fixedly connected to the cylinder 23.

[0095] The drive end of the cylinder 23 is connected to the second bearing 92.

[0096] In this implementation, the second bearing seat 92 and the second connecting shaft 93 are driven to move back and forth relative to the bushing 91 by the extension and retraction of the cylinder 23. When the air expansion shaft 22 is inserted, the cylinder 23 retracts and extends after the air expansion shaft 22 is inserted, so that the second connecting shaft 93 cooperates with the first connecting shaft 82 to clamp the air expansion shaft 22, thereby realizing the picking, placing and stable rotation of the air expansion shaft 22.

[0097] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
