Description

Technical Field

[0001] The utility model relates to the field of aluminum foil processing equipment, in particular to a horizontal slitting mechanism. Background Art

[0002] Aluminum foil needs to be slit during processing, and the slitting machine can slit wide aluminum foil coils into multiple narrow aluminum foil coils for subsequent use. Existing slitting machines generally use an unadjustable knife holder to fix multiple disc knives, and the disc knives are actively rotated to achieve aluminum foil cutting. Due to the rapid rotation of the disc knives, the aluminum foil will produce a lot of aluminum powder. These aluminum powders accumulate on the surface of the aluminum foil. After being reeled up by the reel, the aluminum powder will have a great impact on the surface of the thinner aluminum foil.

[0003] The existing publication number is CN 209536598 U. A high-cleanliness battery aluminum foil slitting device comprises an unwinding mechanism, a corona mechanism, a slitting mechanism, comprising a cutter and a slitting roller, wherein the cutter can slitting the aluminum foil passing through the slitting roller; a cleaning mechanism, arranged between the slitting mechanism and the winding mechanism, wherein the cleaning mechanism is used to clean foreign matter on the surface of the aluminum foil after slitting;

[0004] The above scheme has the following defects: 1. The cleaning mechanism can clean a fixed width, which is only effective for aluminum foil of a specific width after slitting. 2. The aluminum foil needs to be turned through many rotating rollers to achieve different purposes and effects. Since the aluminum foil itself is relatively thin, it is easy to break or crack after multiple turns. 3. When the aluminum foil is wound too tightly by the winding roller, it is difficult to remove the aluminum foil from the winding roller. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-3 As shown, an embodiment of the utility model provides a horizontal slitting mechanism, including a frame 1, a conveying roller 2 is provided on one side of the frame 1, and a winding roller 3 is provided on the other side, an aluminum foil 4 rotates on the conveying roller 2, a cutting frame 5 is provided on the frame 1, and a T-shaped slot parallel to the winding roller 3 is provided on the cutting frame 5, a T-shaped block 6 slides in the T-shaped slot, a cutting knife 7 is fixed to the bottom of the T-shaped block 6 through a connecting rod, two horizontally arranged supporting rollers 8 are rotated on the frame 1 below the cutting knife 7, the blade of the cutting knife 7 is placed between the supporting rollers 8, and the blade is close to the conveying roller 2, an oblong hole 10 corresponding to the moving path of the T-shaped block 6 is provided on the T-shaped slot, the T-shaped block 6 is connected to a fixing component 9, and the fixing component 9 moves along the oblong hole 10, a tensioning roller component 27 is provided on the side of the cutting frame 5 close to the winding roller 3, and a dust suction component is provided between the cutting frame 5 and the tensioning roller component 27. The fixing assembly 9 can be a bolt or a telescopic cylinder. If it is a bolt, the small end of the bolt is inserted into the T-slot through an oblong hole 10, and the bolt is screwed to the T-block 6. By rotating the bolt, the friction between the T-block 6 and the T-slot is increased. If it is a telescopic cylinder, the telescopic cylinder slides in the oblong hole 10, and the telescopic end of the telescopic cylinder is fixedly connected to the T-block 6. The T-block 6 is fixed by the telescopic cylinder. As long as the friction between the T-block 6 and the T-slot can be increased, the effect of fixing the T-block 6 can be achieved.

[0027] During use, the aluminum foil 4 passes through the cutting frame 5, and the blade of the cutting knife 7 on the cutting frame 5 is placed between two supporting rollers 8. The support of the supporting rollers 8 ensures the stability and cutting quality of the aluminum foil 4 during the cutting process. Through the passive cutting cutting knife 7, the friction and extrusion force on the aluminum foil 4 are small, and the friction heat is less, so the generation of aluminum powder will be reduced accordingly, achieving the effect of reducing the generation of aluminum powder from the source. The position of the T-shaped block 6 in the T-shaped groove is adjusted by the fixing component 9, so as to adjust the cutting width, thereby meeting the demand that different specifications of aluminum foil 4 can be produced in the same batch. After the aluminum foil 4 is cut by the cutting knife 7 on the cutting frame 5, it enters the dust collection component. The dust, aluminum powder and debris on the surface of the aluminum foil 4 can be removed in time during the cutting process through the dust collection component to avoid the aluminum foil 4 from being contaminated, and the cutting environment can be kept clean. After the aluminum foil 4 passes through the dust collection component, the tension of the aluminum foil 4 is accurately controlled by the tension roller component 27, ensuring that the aluminum foil 4 maintains a constant tension during the slitting process, avoiding cutting quality problems caused by tension changes.

[0028] The dust collection assembly includes a dust collection bin 11, which is provided with a cleaning hole 12 for the aluminum foil 4 to pass through, a main pipeline 13 running through the dust collection bin 11, and a plurality of branch pipelines are connected to the main pipeline 13, and a trumpet-shaped dust collection port 14 is fixed at the end of the branch pipeline, and the large end of the dust collection port 14 is close to the upper surface of the aluminum foil 4. A cleaning plate 15 is fixed in the dust collection bin 11, and a through hole is provided on the cleaning plate 15 for the branch pipeline to pass through, and a brush 16 is fixed on the bottom surface of the cleaning plate 15, and the brush 16 is against the upper surface of the aluminum foil 4, and the main pipeline 13 is connected to a dust collection device. The brush 16 is preferably made of anti-static PA material, electrostatically conductive nylon fiber or carbon fiber, etc., which reduces the static electricity that may be generated during the cleaning process, helps prevent dust from being adsorbed on the aluminum foil 4 due to static electricity, and improves the cleaning efficiency and quality. The dust collection device is a prior art, such as a vacuum cleaner or a negative pressure generator.

[0029] When the aluminum foil 4 carrying aluminum powder enters the dust collection bin 11, the brush 16 makes the aluminum powder float by friction with the aluminum foil 4. At this time, the vacuum cleaner absorbs the aluminum powder through the dust suction port 14 of the branch pipeline. The trumpet-shaped dust suction port 14 can reduce the local suction force, expand the powder suction range, and prevent the aluminum foil 4 from being damaged. The cleaning plate 15 is provided with a through hole for the branch pipeline to pass through. The branch pipeline can pass through the through hole and get closer to the surface of the aluminum foil 4, ultimately enhancing the dust collection effect. In addition, the cleaning plate 15 fixes the brush 16 made of special material to prevent the brush 16 from generating static electricity to absorb the floating aluminum powder, and avoid the static electricity generated by the friction of the brush 16 to absorb more dust or aluminum powder, so as to prevent the aluminum powder on the brush 16 from scratching the surface of the aluminum foil 4.

[0030] like Figure 2 , 3As shown in FIG. 7 , a vibrator is fixed on the cleaning plate 15, and a second dust collecting assembly connected to the first dust collecting assembly is provided on the lower surface of the aluminum foil 4, and the dust collecting port 14 is placed in the brush 16. The vibrator is a prior art, and the aluminum powder on the brush 16 can be shaken off by the vibrator to prevent the aluminum powder from accumulating on the brush 16 and scratching the aluminum foil 4. The second dust collecting assembly can clean the dust or aluminum powder adsorbed by static electricity on the lower surface of the aluminum foil 4, and can also clean the aluminum powder that is not completely sucked out by the first dust collecting assembly in the dust collecting bin 11 and falls under the aluminum foil 4 under the action of gravity. The second dust collecting assembly is combined with the first dust collecting assembly to achieve comprehensive cleaning of the upper and lower surfaces of the aluminum foil 4, greatly improving the overall cleaning efficiency.

[0031] like Figure 4 As shown, the winding roller 3 includes a bracket 17, on which a winding roller 18 is rotated, a plurality of through holes are opened on the side wall of the winding roller 18, support plates 19 are fixed at both ends of the winding roller 18, a conical main roller 20 is arranged inside the winding roller 18, and both ends of the main roller 20 are rotatably connected to the support plate 19 through a rotating shaft, a plurality of fan-shaped support members 21 are evenly distributed between the main roller 20 and the winding roller 18, the main roller 20 is threadedly connected to the support member 21, the inner side wall of the support member 21 is fitted with the main roller 20, and the support member 21 is provided with a support tooth 22 passing through the through hole, the length of the main roller 20 is less than the length of the winding roller 18, when the large end of the main roller 20 abuts against the adjacent support plate 19, a gap is provided between the outer side wall of the support member 21 and the inner wall of the winding roller 18, and the support tooth 22 is placed in the through hole, the axes of the winding roller 18, the rotating shaft, the main roller 20 and the support member 21 coincide, one end of the rotating shaft passes through the support plate 19, and a handle is fixed thereto.

[0032] In order to prevent the support roller 8 from being unable to support the weight of the aluminum foil 4 after winding, during use, the main roller 20 is rotated by the rotating shaft, and the main roller 20 moves along the axis of the winding roller 18 under the action of the threaded connection. When the small end of the main roller 20 moves toward the adjacent support plate 19, the inner diameter of the support member 21 is gradually expanded by the tapered main roller 20, and the support teeth 22 move outward and protrude from the through hole. When it is necessary to disassemble the coiled material after winding, the main roller 20 is rotated so that the large end of the main roller 20 is against the adjacent support plate 19. At this time, the inner diameter of the support member 21 is reduced, and when the support teeth 22 are subjected to external force, they will shrink into the through hole. Through the self-locking property of the threaded connection, the support teeth 22 can maintain a fixed position even when it is running for a long time or subjected to a large external force, providing stable support for winding and achieving the effect of quickly disassembling the rolled aluminum foil 4.

[0033] like Figure 1 and 5As shown, a clamp 23 is hinged on the bracket 17, and the roller 18 rotates in the clamp 23 through a driving motor. The roller 18 is rotatably connected to the clamp 23 and the bracket 17 through a ball bearing. When the aluminum foil 4 needs to be rolled up, the driving motor is started to rotate the roller 18. The roller 18 can be easily disassembled through the clamp 23, making the work of replacing the roller 18 simple and quick, improving work efficiency. When the roller 18 has problems or needs maintenance, the clamp 23 allows the roller 18 to be easily disassembled and replaced, which is convenient for daily maintenance. The roller 18 rotates on the bracket 17 through a ball bearing. The use of the ball bearing reduces friction and wear during the rotation process and prolongs the service life of the roller 18.

[0034] like Figure 2 and 6 As shown, the cutting frame 5 is hinged with a positioning rod 24 through a connecting rod, and a positioning block 25 is slid on the positioning rod 24, a push plate is provided on one side of the positioning block 25, and a scale is provided on the positioning rod 24. During use, the positioning rod 24 is rotated by the connecting rod to make the positioning rod 24 abut against the support roller 8, and the push plate is fixed on one side of the positioning block 25, and the push plate abuts against the tool. The tool is pushed by sliding the positioning block 25, and the corresponding scale of the positioning block 25 on the positioning rod 24 is observed to ensure the position of the blade. The rotatable positioning rod 24 can keep the positioning rod 24 away from the aluminum foil 4 when there is no need to adjust the position of the tool, so as to prevent the positioning rod 24 from causing damage to the aluminum foil 4. The positioning rod 24 and the positioning block 25 can prevent the staff from directly contacting the blade, thereby reducing the safety risks during work.

[0035] like Figure 5 As shown, the two ends of the winding roller 3 are fixed with hanging ears 26, and the hanging ears 26 and the winding roller 3 form a hanging hole, and the axis of the hanging hole is perpendicular to the axis of the winding roller 3. The hanging ears 26 are provided to facilitate the lifting device to move the rolled aluminum foil 4, and the axis of the hanging hole is perpendicular to the axis of the winding roller 3, which can facilitate the forklift to move the winding roller 3. The lifting device is positioned by the hanging ears 26, which can avoid scratches or indentations on the surface of the winding roller 3 during the movement, and protect the integrity of the aluminum foil 4 roll.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
