[0026] The present application will be further described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without making creative changes are within the protection scope of the present application.

[0027] like Figures 1-2 As shown, the technical solution adopted by this utility model is a battery aluminum foil cutting device, including a cutting roller 1, a blade 2, an adjustment mechanism, a lubrication release mechanism 5, a liquid receiving tray 6, and a return tank 7.

[0028] The system includes a cutting roller 1, through which aluminum foil passes, and cutting grooves 11 at both ends; a blade 2, which engages with the cutting grooves 11 and is driven by a motor 21 to cut the aluminum foil edges; an adjustment mechanism for adjusting the position of the blade 2 in the axial direction of the cutting roller 1; a lubrication release mechanism 5, located on one side of the blade 2, for providing lubricant to the blade 2; a drip tray 6, located below the lubrication release mechanism 5, for receiving the lubricant dripped from the lubrication release mechanism 5; and a return tank 7, located below the drip tray 6, for collecting the lubricant in the drip tray 6.

[0029] As shown in the figure, the cutting roller 1, the disc-shaped blade 2, and the adjustment mechanism are mounted on the frame 10. Multiple cutting grooves 11 are provided at both ends of the cutting roller 1 along its axial direction. The blades 2 are positioned at both ends of the cutting roller 1. During operation, the position of the blades 2 relative to the cutting roller 1 is adjusted according to the width of the aluminum foil to be cut, thus matching the cutting operation of aluminum foil of different widths. The motor 21 drives the blades 2 to rotate, and the blades 2 engage with the cutting grooves 11 to cut the aluminum foil between the blades 2 and the cutting grooves 11. During the cutting process, the lubrication release mechanism 5 continuously supplies lubricant to the blades 2, which facilitates cutting lubrication and heat dissipation, thereby ensuring effective cutting and extending the service life of the blades 2. Excess lubricant drips from the lubrication release mechanism 5 into the drip tray 6, preventing lubricant from dripping onto the cut aluminum foil. The lubricant in the drip tray 6 can be collected using the return tank 7 for easy recycling.

[0030] Specifically, in some embodiments, the adjustment mechanism includes a slide rail 3, which is arranged axially along the cutter roller 1. A slider 4 is provided on the slide rail 3, and a motor 21 is mounted on the slider 4. The blade 2 is mounted on the output end of the motor 21. The liquid receiving tray 6 and the return tank 7 are mounted on the slider 4. The slider 4 is also provided with a fixing mechanism to fix the slider 4 on the slide rail 3. Specifically, the slide rail 3 is set on the frame 10, and the slider 4 can move on the slider 4 to adjust the position of the blade 2, the liquid receiving tray 6, and the return tank 7. After the position is adjusted, the slider 4 is fixed by the fixing mechanism. The fixing mechanism can be a fixing bolt structure, with threaded holes provided on the slider 4. The bolt is screwed into the threaded holes, and after tightening, one end of the bolt abuts against the slide rail 3, thereby fixing the slider 4. To facilitate tightening, one end of the bolt is provided with a handle 41.

[0031] In some embodiments, to facilitate the installation of the motor 21 and the lubrication release mechanism 5, a fixing frame 22 is provided on the outside of the motor 21, the motor 21 is mounted on the slider 4 through the fixing frame 22, and the lubrication release mechanism 5 is disposed on the fixing frame 22.

[0032] In some embodiments, to effectively apply lubricant to the blade 2, the lubrication release mechanism 5 includes a mounting bracket 51, a sponge block 52, and an adjustment mechanism 53. The mounting bracket 51 is mounted on the fixing bracket 22 and has a mounting cavity with an opening on the side facing the blade 2. The sponge block 52 is installed in the mounting cavity. The adjustment mechanism 53 is disposed on the mounting bracket 51 and is used to press the sponge block 52 toward the blade. Specifically, the adjustment mechanism 53 may be an adjustment bolt, which is threadedly connected to the mounting bracket 51, with one end extending toward the blade. By installing the sponge block 52 in the mounting cavity and turning the adjustment bolt, the length of the adjustment bolt in the mounting cavity can be adjusted, thereby pushing the sponge in the mounting cavity out of the opening of the mounting cavity, so that the sponge block 52 directly contacts the blade 2, and the lubricant stored in the sponge can be applied to the blade 2. After a period of use, the sponge block 52 may wear out and separate from the blade 2. At this time, simply turn the adjusting bolt to push the sponge block 52 out of the opening until it is in close contact with the blade 2. Setting the thickness of the sponge block 52 to 15-20mm can reduce the replacement time of the sponge block 52.

[0033] In some embodiments, to replenish the lubricating fluid stored in the sponge block 52 of the lubrication release mechanism 5, a fluid supply mechanism is also included. The fluid supply mechanism includes a storage bottle 9, a supply pipe 91, and a flow regulator 92. The supply pipe 91 connects the storage bottle 9 and the lubrication release mechanism 5. The flow regulator 92 controls the flow rate of the lubricating fluid in the supply pipe 91. The storage bottle 9 stores lubricating fluid and can be fixed at a high position on the frame 10. Under gravity, lubricating fluid is continuously supplied to the sponge block 52 through the supply pipe 91. The flow regulator 92 can adjust the flow rate of the lubricating fluid in the supply pipe 91; the flow regulator 92 can be a valve, preferably a medical infusion flow rate regulator. To fix the supply pipe 91, a fixing clip 93 is used to fix the supply pipe 91 to the frame 10.

[0034] like Figure 2 As shown, specifically, in some embodiments, the drip tray 6 is inclinedly disposed at the bottom of the lubrication release mechanism 5, with the end near the lubrication release mechanism 5 being higher and the lower end located above the return tank 7. The drip tray 6 is inclinedly disposed at the bottom of the sponge block 52 of the lubrication release mechanism 5, allowing the lubricating fluid dripping from the sponge block 52 to flow naturally into the return tank 7.

[0035] like Figure 1As shown, in some embodiments, a waste liquid tank 8 is also provided at the bottom of the return tank 7, and the waste liquid tank 8 is connected to the return tank 7 through a return pipe 71. By fixing the waste liquid tank 8 on the frame 10 and preventing it from moving with the slider 4, the lubricating fluid flowing out of the return tank 7 can be effectively collected, avoiding the problem of excessive lubricating fluid overflowing from the return tank 7.

[0036] like Figure 3 As shown, specifically, in some embodiments, to filter out solid impurities such as debris generated during edge trimming, a filtration mechanism 72 is provided at the bottom of the return tank 7. The filtration mechanism 72 includes a filter tube 721 and a filter head 722. The filter head 722 is disposed at one end of the filter tube 721. A fixing mesh plate 723 and filter cotton 724 are disposed inside the filter tube 721. The return pipe 71 is connected to the filter tube 721. First, the filter head 722 blocks large impurities outside its surface. Then, the filter cotton 724 performs a second filtration to block smaller impurities. Simultaneously, the fixing mesh plate 723 effectively secures the filter cotton 724. Preferably, the filter head 722 is hemispherical, which provides a larger filtration area compared to a plate shape.

[0037] Specifically, such as Figure 1 As shown, in some embodiments, a balloon 73 is also provided on the return pipe. Normally, the lubricating fluid in the return tank 7 flows naturally into the waste liquid tank 8 under the action of gravity through the filter mechanism 72 and the return pipe 71. However, when the filter mechanism 72 is severely blocked, the inflow rate of the lubricating fluid in the return tank 7 is greater than the outflow rate, which will cause the lubricating fluid to overflow from the return tank 7. When there is too much lubricating fluid in the return tank 7, the balloon 73 can be pressed. On the one hand, it can backwash the filter mechanism 72 to prevent the filter mechanism 72 from becoming blocked. On the other hand, when the balloon 73 returns to its original shape under the action of elasticity, it can draw out the lubricating fluid from the return tank 7, which is conducive to the lubricating fluid being discharged into the waste liquid tank 8.

[0038] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this application.
