DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with specific implementation methods. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative changes belong to the protection scope of the present invention.

[0025] like Figures 1 to 5 As shown, the technical solution adopted by the present invention is a lithium battery aluminum foil cutting device capable of cooling and cleaning a blade, comprising a base 1 and a cutting mechanism, wherein a fixing groove 5 is provided on the base 1, and the cutting mechanism is arranged above the fixing groove 5;

[0026] like Figure 4As shown, the cutting mechanism includes a mounting plate 4 and a cutting knife 21 slidably arranged on the cutting plate, a cooling mechanism and a cleaning mechanism are arranged at the bottom of the mounting plate 4, the cooling mechanism includes a cooling cavity 31 arranged on the mounting plate 4, a cooling medium is arranged in the cooling cavity 31, the cleaning mechanism includes an ash collecting cavity 26 arranged on the mounting plate 4, a negative pressure mechanism, and an ash suction hole 29 arranged toward the cutting knife 21, the ash suction hole 29 is connected to the ash collecting cavity 26, and the negative pressure mechanism is used to form a negative pressure on the ash suction hole 29.

[0027] When in use, the aluminum foil is fixed in the fixed groove 5, and the aluminum foil is cut by the cutting knife 21 of the cutting mechanism. During the cutting process, since there is a cooling medium in the cooling chamber 31 of the cooling mechanism, the cutting knife 21 can be cooled and cooled to prevent the temperature of the cutting knife 21 from rising during repeated cutting, which will cause adverse effects on the cutting knife 21. At the same time, the cleaning mechanism can absorb and clean the debris generated during the cutting process of the cutting knife 21 and collect it in the dust collection chamber 26 to prevent the debris from affecting the quality of the cut aluminum foil. Two fixed plates 2 can be set on the base 1, which are respectively located at both ends of the fixed groove 5, and a slide rail 3 is set between the fixed plates 2. The cutting mechanism is slidably set on the slide rail 3, and the cutting mechanism is driven by a power mechanism to move on the slide rail 3 to a predetermined position, and the cutting knife 21 is used for cutting. Of course, the cutting knife 21 also needs a power mechanism to drive it to rise and fall (not shown in the figure), so as to realize the cutting function. The power mechanism can be a cylinder, and a pressurized air pump 39 is set on the mounting plate 4 to provide power for the cylinder.

[0028] like Figure 4 and 5 As shown, specifically, in order to improve the cooling effect, in some embodiments, the cooling mechanism further includes an air outlet 35 connected to the cooling chamber 31 and facing the cutting blade 21, and a fan inlet 34 is provided on a side of the cooling chamber 31 away from the air outlet 35. The air in the cooling chamber 31 that has exchanged heat with the cooling medium is passed from the air outlet 35 to the cutting blade 21 by the fan inlet 34 to cool the cutting blade 21.

[0029] like Figure 5As shown, specifically, in order to further improve the cooling effect, in some embodiments, a heat exchange tube 32 and a circulation pipeline 33 are provided in the cooling chamber 31, the heat exchange tube 32 is communicated with the circulation pipeline 33, the circulation pipeline 33 and the heat exchange tube 32 are provided with the cooling medium, and the heat exchange tube 32 is provided between the inlet fan 34 and the air outlet 35. The fan introduces the outside air into the cooling chamber 31, and forms cold air after heat exchange with the heat exchange tube 32, and the cold air is blown out from the air outlet 35 and contacts with the cutting blade 21, which has a cooling effect. The heat exchange between the heat exchange tube 32 and the air has a better cooling effect, wherein a circulation management is provided to circulate the cooling medium in the heat exchange tube 32, and the circulation pipeline 33 can be connected with an external refrigeration mechanism, such as a compressor, to avoid the problem of increased temperature of the cooling medium.

[0030] like Figure 4 and 5 As shown, specifically, in some embodiments, the ash suction hole 29 is connected to the ash collection chamber 26 through the ash suction channel 28, and the ash suction channel 28 is provided with a mounting chamber 27 at one end close to the ash collection chamber 26, and an exhaust fan 30 is provided in the mounting chamber 27. The exhaust fan 30 forms a negative pressure in the ash suction channel 28, and the exhaust fan 30 is the negative pressure mechanism mentioned above, and the ash suction hole 29 has an adsorption effect on external debris, thereby playing a role in cleaning the debris on the cutting blade 21.

[0031] In order to further improve the cleaning effect, in some embodiments, the cleaning mechanism further includes a cleaning roller 24, a cleaning groove 23 is provided on the mounting plate 4, a cleaning sleeve 25 is sleeved on the cleaning roller 24, and the cleaning roller 24 is rotatably arranged in the cleaning groove 23, and the cleaning groove 23 is located above the ash suction hole 29. The cleaning roller 24 drives the cleaning sleeve 25 to rotate, and the debris on the cutting blade 21 is cleaned during the rotation process. The debris dropped after cleaning is adsorbed into the ash collection chamber 26 by the ash suction hole 29, so as to avoid the problem that the debris is adsorbed on the cutting blade 21 but not completely adsorbed. As shown in the figure, the cleaning roller 24 is arranged below the air outlet 35 and above the ash suction hole 29, so as to save the installation space, and at the same time, an air circulation is formed between the air outlet 35 and the ash suction hole 29, so that the debris cleaned by the cleaning roller 24 can naturally fall to the ash suction hole 29 under the action of the gravity of the debris and the air circulation, so as to avoid the debris moving upward with the cutting blade 21.

[0032] like Figure 4 and 5As shown, further, in order to prevent dust and debris formed in the fixing groove 5 from entering the upper part of the mounting plate 4, in some embodiments, the mounting plate 4 is further provided with a dust blocking mechanism at the bottom, the dust blocking mechanism comprising a wedge-shaped dust blocking block 38, a spring groove 37 is provided on the mounting plate 4, the wedge-shaped dust blocking block 38 is slidably arranged in the spring groove 37, and a spring is further arranged between the wedge-shaped dust blocking block 38 and the spring groove 37. The sliding direction of the wedge-shaped dust blocking block 38 is perpendicular to the running direction of the cutting knife 21. When the cutting knife 21 contacts the inclined surface of the wedge-shaped dust blocking block 38, the cutting knife 21 exerts an extrusion effect on the wedge-shaped dust blocking block 38, forcing the wedge-shaped dust blocking block 38 to shrink toward the inside of the mounting plate 4 along the spring groove 37. When the cutting knife 21 is separated from the inclined surface of the wedge-shaped dust blocking block 38, it can extend out of the mounting plate 4 to cut the aluminum foil in the fixing groove 5. After the cutting is completed, the cutting knife 21 rises, and the wedge-shaped dust blocking block 38 can automatically pop out of the spring groove 37 under the action of the spring. When in use, a baffle can also be set on one side of the mounting plate 4 to enclose the cutting knife 21 between the baffle and the mounting plate 4, and the wedge-shaped dust blocking block 38 can close the outlet of the cutting knife 21, and automatically retract under the action of the cutting knife 21 during cutting, which can effectively prevent dust and debris in the fixing groove 5 from entering the space above the wedge-shaped dust blocking block 38.

[0033] like Figure 4 As shown, in order to ensure the smooth movement of the cutting knife 21 on the mounting plate 4, in some embodiments, the mounting plate 4 is provided with a sliding cavity 19 and a knife exit cavity 36 located below the sliding cavity 19, and the cutting knife 21 is slidably arranged in the sliding cavity 19 through the slide plate 20, and the width of the knife exit cavity 36 matches the width of the cutting knife 21, and the positions of the cooling mechanism and the cleaning mechanism on the mounting plate 4 correspond to the positions of the knife exit cavity 36. The sliding connection between the slide plate 20 and the sliding cavity 19 can ensure the smooth sliding of the cutting knife 21, and the matching of the width of the knife exit cavity 36 with the width of the cutting knife 21 can avoid the phenomenon of misalignment during the cutting process. At the same time, the cooling mechanism and the cleaning mechanism correspond to the positions of the knife exit cavity 36, and a cleaning and cooling area 22 of the cutting knife 21 is also formed at the position of the knife exit cavity 36.

[0034] like Figure 1 and 3 As shown, further, in some embodiments, the two sides of the fixed groove 5 are respectively provided with a slide groove 6 and a slide opening 7, and the two ends of the slide rod 8 are respectively slidably arranged in the slide groove 6 and the slide opening 7, and a flattening cylinder 9 is fixedly arranged on the outside of the slide rod 8. As shown in the figure, the slide opening 7 passes through the side wall of the fixed groove 5 and is parallel to the slide groove 6. One end of the slide rod 8 extends out of the slide opening 7 as an operating end. After the aluminum foil is placed in the groove, the slide rod 8 is slid to use the flattening cylinder 9 on it to flatten the aluminum foil to avoid wrinkles.

[0035] like Figure 1 and 3As shown, in order to remove the debris accumulated in the fixed groove 5 during the cutting process, in some embodiments, the bottom of the fixed groove 5 is further provided with an air extraction hole 18, and the base 1 is provided with an air extraction cavity 15, and an air extraction pump 16 is installed in the air extraction cavity 15, and the air extraction pump 16 and the air extraction hole 18 are connected through an air extraction pipe 17. The air extraction pump 16 generates negative pressure suction in the fixed groove 5 through the air extraction hole 18, thereby cleaning the debris generated in the fixed groove 5 during the cutting process. At the same time, the air extraction holes 18 are distributed in an array in the fixed groove 5, and the air extraction holes 18 covered by the aluminum foil can also play a role in adsorbing and fixing the aluminum foil, thereby preventing the aluminum foil from moving during the cutting process.

[0036] like Figure 1 and 2 As shown, in order to further improve the fixing effect of the aluminum foil in the fixing groove 5, in some embodiments, the base 1 is further provided with a fixing cavity 10, in which a pressing plate 12 is slidably provided, one end of the pressing plate 12 extends out of the fixing cavity 10, a pressing block 13 is provided at the bottom of the pressing plate 12, and a return spring 14 is further provided between the pressing plate 12 and the fixing cavity 10, and the fixing cavity 10 is located at one end of the fixing groove 5 and is connected with the fixing groove 5. An extrusion port 11 is provided at the position where the pressing plate 12 extends out of the fixing cavity 10, and when the aluminum foil is placed in the fixing groove 5, the pressing plate 12 is lifted up at one end of the extrusion port 11 extending out of the fixing cavity 10, so that the pressing plate 12 rises, and then the pressing block 13 is separated from the bottom of the fixing cavity 10, and one end of the aluminum foil is placed on the bottom of the pressing block 13, and then the pressing plate 12 is released, and the return spring 14 can press the pressing block 13 on one end of the aluminum foil, and then fix one end of the aluminum foil.
