[0032] As Figures 1 to 4 shown, the present utility model provides a waste film cutting device for cutting the waste film on the core 20, which includes a frame 1, a first driving member 2, a second driving member 3, a third driving member 9, a support table 4 and a placement roller 7. The first driving member 2 is arranged on the frame 1, the output end of the first driving member 2 is provided with the second driving member 3, the output end of the second driving member 3 is provided with a cutter 8, the second driving member 3 drives the cutter 8 to move up and down, and the first driving member 2 drives the cutter 8 to move along a horizontal first direction; the third driving member 9 is arranged on the frame 1, the output end of the third driving member 9 is provided with the support table 4, the support table 4 is provided with a first fixing seat 5 and a second fixing seat 6 arranged at intervals along the first direction, and the third driving member 9 drives the support table 4 to move along the first direction; one end of the placement roller 7 is arranged on the first fixing seat 5, the other end of the placement roller 7 is arranged on the second fixing seat 6, the first fixing seat 5 or the second fixing seat 6 is detachably connected to the placement roller 7, and the core 20 can be sleeved on the placement roller 7. When cutting the waste film is required, the placement roller 7 is removed from the first fixing seat 5 or the second fixing seat 6, then a plurality of cores 20 wound with waste film are sleeved on the placement roller 7 along the axial direction of the placement roller 7, and the placement roller 7 is put back; then the third driving member 9 can be driven to move it along the first direction to the second driving member 3, and then the height of the cutter 8 is adjusted by the second driving member 3. After the height adjustment is completed, the cutter 8 can be driven by the first driving member 2 to move along the first direction to cut the waste film, so that the waste film is separated from the above-mentioned core 20, and thus multiple waste films can be cut at one time, improving the cutting efficiency and not easily damaging the core 20 at the same time.

[0033] In the current embodiment, the first fixing seat 5 and the second fixing seat 6 are arranged along the first direction, so that the placement roller 7 extends along the first direction, enabling the cutting knife 8 to cut off the waste film with a single cut along the first direction. The placement roller 7 is an air shaft roller. The reserved holes of the air shaft roller are inflated by an air inflation pen to fix the air shaft roller to the core 20. The first direction is Figure 1 the x direction in

[0034] As Figure 4 shown, in some embodiments, a fourth driving member 10 is further provided at the output end of the first driving member 2, the second driving member 3 is arranged at the output end of the fourth driving member 10, and the fourth driving member 10 drives the cutting knife 8 to move along the horizontal second direction. The first direction is perpendicular to the second direction. Thus, by combining the horizontal first direction and second direction with the lifting of the cutting knife 8, the cutting knife 8 can move in three directions. Furthermore, the height of the cutting knife 8 can be adjusted in the vertical direction by the lifting of the cutting knife 8, and the cutting position of the cutting knife 8 can be adjusted by the horizontal second direction. Subsequently, the first cutting knife 8 moves in the first direction for cutting. The second direction is Figure 1 the Y direction in

[0035] It should be noted here that the forms of the first driving member 2, the second driving member 3, and the fourth driving member 10 are not limited, and can be in the form of a linear module, a cylinder, or an oil cylinder, etc. In the current embodiment, a linear module is adopted to ensure the stability and accuracy of driving.

[0036] In the current embodiment, two first driving members 2 are provided. The two first driving members 2 are arranged at intervals along the second direction. The fourth driving member 10 is arranged at the output ends of the two first driving members 2, and the second driving member 3 is located between the two first driving members 2, thereby ensuring the stability of the cutting knife 8 during cutting.

[0037] In some embodiments, for the convenience of installation, mounting plates 11 are provided at the output ends of the first driving member 2, the second driving member 3, and the fourth driving member 10. The fourth driving member 10 is arranged on the mounting plate 11 at the output end of the first driving member 2, the second driving member 3 is arranged on the mounting plate 11 at the output end of the fourth driving member 10, and the cutting knife 8 is arranged on the mounting plate 11 at the output end of the second driving member 3.

The protective cover is a prior art and will not be elaborated here.

[0038] As Figure 4As shown, further, in order to ensure that the lifting range of the cutting tool 8 remains within a certain range during cutting and prevent its lifting range from being too large, two proximity switches 12 are spaced up and down on the mounting plate 11 at the output end of the fourth driving member 10. The proximity switches 12 are connected to the second driving member 3. An induction sheet 13 that cooperates with the proximity switches 12 is also provided at the output end of the second driving member 3. When the second driving member 3 drives the cutting tool 8 to lift and lower, the induction sheet 13 can be synchronously driven to lift and lower. When the induction sheet 13 faces the proximity switches 12, the second driving member 3 can be controlled to stop moving, thereby limiting the moving range of the lifting of the cutting tool 8, preventing it from moving too high, and at the same time preventing it from descending too low and damaging the core 20.

[0039] As Figure 3 shown, in order to facilitate placing the core 20 on the placement roller 7, the first fixed seat 5 or the second fixed seat 6 is detachably connected to the placement roller 7, so that at least one end of the placement roller 7 can be detached from the first fixed seat 5 or the second fixed seat 6, and then the core 20 is sleeved onto the placement roller 7 from this end. In some embodiments, one of the first fixed seat 5 and the second fixed seat 6 is provided with a limiting groove, and the other is provided with a clamping hole to be able to clamp and fix the placement roller 7. Thus, one end of the placement roller 7 is inserted and limited in the above-mentioned clamping hole, and the other end of the placement roller 7 is lapped in the above-mentioned limiting groove, so as to facilitate detaching the placement roller 7 from the above-mentioned limiting groove for the operation of sleeving the core 20. It can be understood that in some alternative embodiments, both the first fixed seat 5 and the second fixed seat 6 can be provided with the above-mentioned limiting grooves.

[0040] Further, a lifting driving member 14 is provided on the support table 4. The first fixed seat 5 or the second fixed seat 6 provided with the limiting groove is arranged at the output end of the lifting driving member 14, so that the first fixed seat 5 or the second fixed seat 6 can be lifted during sleeving, avoiding interference when supporting the placement roller 7 after sleeving is completed. Further still, a rotation driving member 15 is also provided on the support table 4. The rotation driving member 15 is arranged on the support table 4, and the lifting driving member 14 is arranged at the output end of the rotation driving member 15, so that the lifting driving member 14 can be driven to rotate and avoid interference during sleeving. Exemplarily, the lifting driving member 14 is a lifting cylinder, and the rotation driving member 15 is a rotation cylinder.

[0041] Further, two sets of the first fixed seat 5 and the second fixed seat 6 are arranged on the support table 4, and the two sets of the first fixed seat 5 and the second fixed seat 6 are spaced along the second direction; thus, two placement rollers 7 can be supported, further improving the cutting efficiency.

[0042] In some embodiments, baffles 16 are provided at both ends of the support table 4 in the second direction, and the baffles 16 can be used to block the waste film after cutting. Further, in order to ensure the strength of the support plate, a plurality of reinforcing ribs are provided on the mutually facing sides of the support plates.
