Lithium-ion batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium-ion battery foil is used as the current collector in lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode current collector. Lithium-ion battery foil is generally produced in long rolls, therefore, during processing, a cutting device is required to cut the lithium-ion battery foil rolls.

[0003] The cutting blades used in the cutting device will wear and develop nicks after prolonged use. To ensure the proper cutting of lithium battery foil and to extend the lifespan of the blades, workers need to disassemble and maintain the blades regularly. Currently, the disassembly and assembly of the blades requires the use of specialized tools and a large number of bolts to secure them, making the process very time-consuming, labor-intensive, and troublesome.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 6As shown, this utility model provides a technical solution for a cutting tool with a blade head disassembly mechanism, including a tool body 1, an mounting plate 2 on the upper part of the tool body 1, a convex groove 3 at the bottom of the mounting plate 2, the convex groove 3 including a coarse groove and a fine groove that are interconnected, a tenon 4 slidably connected in the convex groove 3, the tenon 4 slidably connected in the cavity of the coarse groove, the top of the tool body 1 slidably connected in the cavity of the fine groove, the tenon 4 is installed on the upper part of the tool body 1, grooves are formed on both sides of the inner wall of the convex groove 3 in a linear array, a pin plate 5 is rotatably connected to the inner wall of the groove, the movable end of the pin plate 5 faces away from the groove opening of the convex groove 3, a spring is provided between the movable end of the pin plate 5 and the inner wall of the groove, a pin groove 6 adapted to the pin plate 5 is provided at the corresponding position of the tenon 4 relative to each groove, and an adjustment mechanism 7 for adjusting the movement of the pin plate 5 is provided on the mounting plate 2;

[0024] When installing the tool body 1, simply insert the tool body 1 into the cavity of the convex groove 3 through the opening of the groove 3. At this time, the end of the tool body 1 will push the pin plate 5 to slide completely into the groove cavity along the inclined surface of the pin plate 5. At this time, the spring is compressed until the tool body 1 is completely inserted into the cavity of the convex groove 3. The pin groove 6 on the tool body 1 will correspond to the groove. The spring force will cause the movable end of the pin plate 5 to pop out and lock into the cavity of the pin groove 6, thereby limiting the position of the tool body 1.

[0025] like Figure 4 As shown, the adjustment mechanism 7 includes a main rope 701, a pin plate 5 located on one side of the groove and a branch rope 702 fixedly connected thereto, the movable end of the branch rope 702 being fixedly connected to one side of the main rope 701, a spring being slidably sleeved on the outside of the branch rope 702, a main groove being opened at one end of the mounting plate 2 and slidably connected to the main rope 701, a through-connected branch groove being formed between the main groove and each groove, and the branch rope 702 being slidably connected in the cavity of the branch groove;

[0026] By pulling the main rope 701, the main rope 701 simultaneously pulls each branch rope 702, which in turn pulls the movable end of the pin plate 5, causing the movable end of the pin plate 5 to slide into the groove cavity. This allows the movable end of the pin plate 5 to disengage from the pin groove 6 cavity, thus facilitating the disassembly of the tool body 1.

[0027] like Figure 4 As shown, a rotatable wheel 8 is rotatably connected to the inner wall of the branch trough, and the outer side of the rotatable wheel 8 contacts the bend of the branch rope 702.

[0028] The spool 8 is used to facilitate changing the direction of force on the branch rope 702 and to make the branch rope 702 slide stably.

[0029] like Figure 4 and Figure 5As shown, the movable end of the main rope 701 is fixedly connected to a pull ring 9, and both sides of the mounting plate 2 are fixedly connected to hanging rods 10, which cooperate with the pull ring 9.

[0030] The pulled-out ring 9 can be hung on the hanging rod 10 to stabilize the position of the main line rope 701, thus avoiding the need for workers to operate with both hands.

[0031] like Figure 5 As shown, both sides of the mounting plate 2 are fixedly connected with linearly arrayed fixing plates 11. The upper part of the fixing plate 11 has two through fixing holes 15, which are located on both sides of the mounting plate 2.

[0032] like Figure 3 - Figure 5 As shown, a push plate 12 is slidably connected inside the cavity of the convex groove 3. A threaded rod 13 is fixedly connected to one side of the push plate 12. A threaded tube 14 is threadedly sleeved at one end of the threaded rod 13. A through hole is formed on the inner wall of the convex groove 3. The threaded tube 14 is rotatably connected inside the through hole cavity.

[0033] After the tool body 1 is installed on the mounting plate 2, simply rotate the threaded tube 14. The threaded tube 14 will then use the threaded rod 13 to drive the push plate 12 to slide in the cavity of the convex groove 3, and make the push plate 12 contact and squeeze the tool body 1 located in the cavity of the convex groove 3. This will improve the stability of the tool body 1 installation.

[0034] like Figure 1 As shown, a connecting plate 16 is provided on the upper part of the mounting plate 2, and a bearing plate 17 is provided above the connecting plate 16. A hydraulic telescopic rod 18 is installed at the bottom of the bearing plate 17. The telescopic end of the hydraulic telescopic rod 18 is fixedly connected to the upper part of the connecting plate 16. The connecting plate 16 has through holes at corresponding positions of each fixing port 15. Bolts are inserted between the fixing port 15 and the corresponding through holes. A nut is threaded on the top of the bolt, and a nut is fixedly connected to the bottom of the bolt. The nut contacts the bottom of the fixing plate 11, and the nut contacts the upper part of the connecting plate 16.

[0035] The specific related structures of the bearing plate 17 and the hydraulic telescopic rod 18, as well as the connection methods and usage methods of the related structures, are all existing technologies. For a detailed description, please refer to the authorization announcement number CN220699844U, "A cutting tool for lithium battery foil". This application will not elaborate further.

[0036] The mounting plate 2 is fixed to the telescopic end of the hydraulic telescopic rod 18 in advance using bolts. After that, the tool body 1 can be removed and installed on the mounting plate 2.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
