[0033] Figure 1 This is a schematic diagram of the overall structure of a cutter lubrication mechanism according to an embodiment of the utility model. Figure 2 This is a cross-sectional view of a cutter lubrication mechanism according to an embodiment of the utility model.

The embodiment of the utility model solves the technical problem of the prior art that it is time-consuming and laborious to manually apply lubricant to the blade surface by arranging the lubricating mechanism 1 above the rotating cutter 23, and can also avoid the risk of human hands being cut by the sharp blade due to manual operation.

[0034] like Figure 1 and Figure 3 As shown, in some embodiments, the lubricating mechanism 1 further includes: a cover 13 and a dripping tube 14, wherein the cover 13 is disposed on the top of the outer shell 11 and the inner shell 12, and the dripping tube 14 extends from the cover 13 to the inner shell 12. The dripping tube 14 can use a quantitative liquid inlet tube to control the amount of lubricant inlet.

[0035] In some embodiments, the lubricating component is a sponge, which can not only absorb the dripping liquid, but also keep the dripping liquid sufficient to fully lubricate the rotary cutter 23.

[0036] In some embodiments, the inner shell 12 is a semi-cone structure, and the cross-sectional area of ​​the top of the semi-cone structure is larger than the cross-sectional area of ​​the bottom of the semi-cone structure. That is, in this embodiment, the upper end of the inner shell 12 is larger than the lower end, so the lubricant can move along the inclined surface of the side wall of the inner shell 12 toward the blade direction of the rotating cutter 23, avoiding the lubricant from dripping onto the membrane surface below.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, a liquid receiving groove 112 is disposed at the bottom end of the outer shell 11 , and the liquid receiving groove 112 is respectively located on both sides of the rotary cutter 23 for receiving liquid dripping from the inner shell 12 .

It can also avoid the risk of human hands being cut by the sharp blade due to manual operation, while ensuring the quality of film cutting and greatly improving the efficiency of film cutting.

[0039] Figure 5 : is a side view of a film slitting device according to an embodiment of the utility model, such as Figure 5 As shown, an embodiment of the utility model further provides a film slitting device, which includes: a rotating shaft 21, a mounting mechanism 22, a rotating cutter 23, and a cutter lubrication mechanism 1 of a rotating motor 24; wherein the mounting mechanism 22 is mounted on the rotating shaft 21; the rotating cutter 23 is mounted on a first mounting plate 221 of the mounting mechanism 22 through the rotating motor 24, the cutter lubrication mechanism 1 is mounted on a second mounting plate 222 of the mounting mechanism 22, the second mounting plate 222 is mounted on the first mounting plate 221, and the cutter lubrication mechanism 1 is located above the rotating cutter 23.

[0040] The film slitting device 2 provided in the embodiment of the utility model can lubricate the rotating cutter 23 while cutting the film, thereby reducing the wear of the rotating cutter 23 to ensure the normal operation of the cutting work, solving the time-consuming and labor-intensive technical problem of manually applying lubricant to the blade surface in the prior art, and avoiding the risk of human hands being cut by the sharp blade due to manual operation. At the same time, it can ensure the quality of film cutting and greatly improve the efficiency of film cutting.

[0041] like Figure 5As shown, in some embodiments, a correction spring 25 is provided between the rotary cutter 23 and the rotary motor 24, and the correction spring 25 is used to prevent the rotary cutter 23 from deflecting. Since the rotary cutter 23 may deflect slightly during the slitting process, the correction spring 25 can provide support to prevent the direction of the blade of the rotary cutter 23 from deflecting and thus affecting the slitting position. By providing the correction spring 25, the embodiment of the utility model can prevent the direction of the blade of the rotary cutter 23 from deflecting and thus affecting the slitting position.

Figure 6 As shown, in some embodiments, the film slitting device 2 further includes a dust removal mechanism 26, which is disposed on the side of the rotary cutter 23. The dust removal mechanism 26 includes a track 261, and an upper dust sticking roller 262 disposed on the track 261, the dust sticking roller 262 is respectively located on both sides of the rotary cutter 23 and in contact with the rotary cutter 23, and in addition, the dust removal mechanism 26 further includes an elastic fixing member 263, which is disposed on the outer side of the dust sticking roller 262 on both sides of each rotary cutter 23, and is used to make the dust sticking roller 262 in close contact with the rotary cutter 23 to improve the dust removal effect, wherein the elastic fixing member 263 can be a rubber band or other elastic material.

[0044] The embodiment of the utility model sets a dust sticking roller 262 on the edge of the rotary cutter 23 to remove dust adhering to the outer periphery of the circular rotary cutter 23 during the film slitting process, which affects the film cutting quality. For example, dust adhering to the cutting edge of the film will cause the two sides of the rolled film to be thicker in the width direction, thereby affecting the flatness of the rolled film roll. The embodiment of the utility model can remove dust first and then lubricate during use, which not only improves the lubrication effect, but also further improves the film cutting quality.
