Detailed implementation manner

[0022] The present utility model will be further described below in conjunction with embodiments.

[0023] Please refer to Figures 1-5 , the present utility model provides a slitter for electrolytic copper foil, including: a frame 1, the lower sides of the opposite ends of the symmetric side plates of the frame 1 are respectively slidably connected with a feeding shaft 2 or a coiling shaft 5, and several limiting shafts 3 are arranged in the middle of the opposite ends of the symmetric side plates of the frame 1, and an electrolytic copper foil 7 is slidably connected to the outer surfaces of the feeding shaft 2, the coiling shaft 5 and several limiting shafts 3, and a sliding device 6 is fixedly connected to one side of a limiting shaft 3 on the opposite side plates of the frame 1, the upper end of the sliding device 6 is slidably connected with a cutting device 8, and a cleaning device 4 is fixedly connected to the middle of the upper ends of the symmetric side plates of the frame 1.

[0024] Furthermore, as Figure 2 shown, specifically, the sliding device 6 includes a sliding plate 601, a sliding groove 602 is arranged in the middle of the upper end of the sliding plate 601, threaded shafts 603 are arranged in the middle of the front and rear ends of the sliding groove 602, and guide posts 604 are fixedly connected to the upper sides of the front and rear ends of the sliding groove 602. Through the sliding groove 602 and the symmetric guide posts 604 of the sliding device 6, the position and movement track of the slide block 801 of the cutting device 8 can be limited, and the left and right movement of the slide block 801 can be controlled through the threaded shaft 603.

[0025] Furthermore, as Figure 3As shown, it is worth specifically explaining that the cutting device 8 includes a number of sliders 801. A through hole 8011 is provided at the lower end of the middle part of each slider 801. A first limiting groove 8012 is provided in the middle of each slider 801. A second limiting groove 8013 is provided on one side above the first limiting groove 8012 of each slider 801. Through the symmetrical through holes 8011 of the sliders 801, the position and movement trajectory of the sliders 801 of the cutting device 8 are restricted. And through the first limiting groove 8012, the position of the first connecting belt 802 can be restricted. And through the second limiting groove 8013, the position and movement trajectory of the third gear shaft 805 are restricted.

[0026] The working process of this solution is as follows: First, one output end of the servo motor 808 of each cutting device 8 drives the meshing-connected second connecting belt 806 to rotate. The second connecting belts 806 drive the meshing-connected third gear shafts 805 to rotate, that is, drive the second gear shafts 804 to rotate. The second gear shafts 804 drive the meshing-connected first connecting belts 802 to rotate, that is, drive the meshing-connected first gear shafts 803 to rotate. Because the positions of the threaded shaft 603 and the first gear shaft 803 are restricted, when the first gear shaft 803 rotates, it drives the cutting device 8 to move back and forth on the threaded shaft 603. At the same time, a number of sliders 801 are all fitted and threadedly connected to the threaded shaft 603 of the sliding device 6. And the other output end of the servo motor 808 drives the meshing-connected driving shafts 809 to rotate. The rotation of the driving shafts 809 drives the cutting blades 810 to rotate. Then, the air pump 405 of the cleaning device 4 drives the air flow to pass through the outer surface of the just-cut electrolytic copper foil 7 for cleaning, and blows the debris on the outer surface of the just-cut electrolytic copper foil 7 into the collection bin 402.

[0027] According to the above working process, it can be known that: Through the sliding groove 602 and the symmetrical guide posts 604 of the sliding device 6, the position and movement trajectory of the sliders 801 of the cutting device 8 can be restricted. And through the threaded shaft 603, the left and right movement of the sliders 801 can be controlled. Through the symmetrical through holes 8011 of the sliders 801, the position and movement trajectory of the sliders 801 of the cutting device 8 are restricted. And through the first limiting groove 8012, the position of the first connecting belt 802 can be restricted. And through the second limiting groove 8013, the position and movement trajectory of the third gear shaft 805 are restricted.

[0028] Further, as Figure 3As shown, it is worth specifically stating that the through holes 8011 are all fitted and slidably connected to the outer surface of the threaded shaft 603. The middle outer surface of the threaded shaft 603 is threadedly connected to the inner surface of the first gear shaft 803. The outer surfaces of the first gear shafts 803 are all meshed and connected to the inner surface of the lower end of the first connecting belt 802. The outer surfaces of the first connecting belts 802 are all fitted and slidably connected to the first limiting grooves 8012. And the inner surfaces of the upper ends of the first connecting belts 802 are all meshed and connected to the outer surfaces of the second gear shafts 804. One end of each of the second gear shafts 804 is fixedly connected to a third gear shaft 805. The outer surfaces of the third gear shafts 805 are all meshed and connected to a second connecting belt 806. The other ends of the second connecting belts 806 are all meshed and connected to an output end of a servo motor 808. The other output ends of the servo motors 808 are all meshed and connected to a driving shaft 809. A cutting blade 810 is installed at the other end of the driving shaft 809. By means of an output end of each of the servo motors 808 of a plurality of cutting devices 8, the second connecting belts 806 engaged and connected are driven to rotate. The second connecting belts 806 all drive the third gear shafts 805 engaged and connected to rotate, that is, drive the second gear shafts 804 to rotate. The second gear shafts 804 all drive the first connecting belts 802 engaged and connected to rotate, that is, drive the first gear shafts 803 engaged and connected to rotate. Because the positions of the threaded shaft 603 and the first gear shaft 803 are restricted, the first gear shaft 803 rotates. And at the same time, a plurality of sliders 801 are all fitted and threadedly connected to the threaded shaft 603 of the sliding device 6. And the other output ends of the servo motors 808 all drive the driving shafts 809 engaged and connected to rotate. The rotation of the driving shafts 809 all drives the cutting blades 810 to rotate. Thus, multiple electrolytic copper foils 7 can be cut at one time freely, and the cutting device 8 can be adjusted freely, thereby improving the cutting efficiency of the electrolytic copper foil 7.

[0029] Further, as Figure 3 shown, it is worth specifically stating that symmetric sliding holes 807 are provided at the upper ends of the front and rear sides of the slider 801. The symmetric sliding holes 807 are all fitted and slidably connected to the outer surface of the symmetric guide posts 604. And a baffle 811 is fixedly connected to the servo motor 808 outside the cutting blade 810. By means of the symmetric sliding holes 807 being fitted and sliding on the outer surface of the symmetric guide posts 604, the stability of the operation of the slider 801 is further increased.

[0030] Further, as Figure 4 and Figure 5As shown, it is worth specifically explaining that the cleaning device 4 includes a cleaning box 401. A collection bin 402 is provided in the middle of the cleaning box 401. Second grooves 409 are provided at the upper ends of the left and right sides of the collection bin 402, and first grooves 406 are provided at the upper ends of the front and rear sides of the collection bin 402. An air pump 405 is provided at the outer end of the first groove 406 on the rear side of the collection bin 402. Air inlet covers 408 are provided on both sides of the air pump 405. A second filter screen 407 is provided at the outer end of the first groove 406 on the front side of the collection bin 402. A first filter plate 403 is installed at the upper end of the inner surface of the collection bin 402. Fixed plates 404 are fixedly connected to the inner surfaces of the left and right sides of the collection bin 402 at the lower end of the first filter plate 403. The air pump 405 of the cleaning device 4 drives the air flow to pass through the outer surface of the just-cut electrolytic copper foil 7 for cleaning, preventing debris from remaining on the outer surface of the just-cut electrolytic copper foil 7, which may cause scratches on the outer surface of the later limiting shaft 3 and the electrolytic copper foil 7, thus affecting the use of the later electrolytic copper foil 7.

[0031] Further as Figure 4 shown, it is worth specifically explaining that the diameter of the upper end of the filter holes of the first filter plate 403 is larger than that of the lower end, and the symmetric fixed plates 404 are both in a downward arc shape. Through the shape of the filter holes of the first filter plate 403 and the fact that the fixed plates 404 fixedly connected to the inner surfaces on both sides of the collection bin 402 are both in a downward arc shape, the flow trajectory of the air flow driven by the air pump 405 will not be changed, thereby increasing the practicability of the slitter for electrolytic copper foil.

[0032] In summary: First, one output end of the servo motor 808 of each cutting device 8 drives the rotation of the second connecting belt 806 engaged therewith. The second connecting belt 806 drives the rotation of the third gear shaft 805 engaged therewith, that is, drives the rotation of the second gear shaft 804. The second gear shaft 804 drives the rotation of the first connecting belt 802 engaged therewith, that is, drives the rotation of the first gear shaft 803 engaged therewith. Since the positions of the threaded shaft 603 and the first gear shaft 803 are restricted, the rotation of the first gear shaft 803 drives the cutting device 8 to move back and forth on the threaded shaft 603. At the same time, a plurality of sliders 801 are all fitted and threadedly connected to the threaded shaft 603 of the sliding device 6, and the other output end of the servo motor 808 drives the rotation of the drive shaft 809 engaged therewith. The rotation of the drive shaft 809 drives the rotation of the cutting blade 810. Then, the air pump 405 of the cleaning device 4 drives the air flow to pass through the outer surface of the electrolytic copper foil 7 that has just been cut for cleaning, and blows the debris existing on the outer surface of the just-cut electrolytic copper foil 7 into the collection bin 402. By one output end of the servo motor 808 of each cutting device 8 driving the rotation of the second connecting belt 806 engaged therewith, the second connecting belt 806 drives the rotation of the third gear shaft 805 engaged therewith, that is, drives the rotation of the second gear shaft 804. The second gear shaft 804 drives the rotation of the first connecting belt 802 engaged therewith, that is, drives the rotation of the first gear shaft 803 engaged therewith. Since the positions of the threaded shaft 603 and the first gear shaft 803 are restricted, the first gear shaft 803 rotates. At the same time, a plurality of sliders 801 are all fitted and threadedly connected to the threaded shaft 603 of the sliding device 6, and the other output end of the servo motor 808 drives the rotation of the drive shaft 809 engaged therewith. The rotation of the drive shaft 809 drives the rotation of the cutting blade 810. Thus, multiple electrolytic copper foils 7 can be cut at one time freely, and the cutting device 8 can be adjusted freely, thereby improving the cutting efficiency of the electrolytic copper foil 7. By the symmetric sliding holes 807 fittingly sliding on the outer surface of the symmetric guide posts 604, the stability of the operation of the sliders 801 is further increased. By the air pump 405 of the cleaning device 4 driving the air flow to pass through the outer surface of the electrolytic copper foil 7 that has just been cut for cleaning, it is prevented that debris exists on the outer surface of the just-cut electrolytic copper foil 7, resulting in scratches on the outer surface of the later limiting shaft 3 and the electrolytic copper foil 7, thereby affecting the later use of the electrolytic copper foil 7. By the shape of the filter holes of the first filter plate 403 and the fixing plates 404 fixedly connected to the inner surfaces on both sides of the collection bin 402 being both in a downward arc shape, the flow track of the air flow driven by the air pump 405 will not be changed, thereby increasing the practicability of the slitter for electrolytic copper foil.
