Detailed Embodiments

[0021] The present invention will be further described in detail below with reference to the drawings.

[0022] As shown Figures 1-5 in the figure, the cutting machine includes a machine table 1, on which a feeding mechanism 2, a material pressing mechanism 3 and a cutting mechanism 4 are arranged side by side. Among them, an outer cover 11 is also arranged on the machine table 1, and the outer cover 11 is located outside the material pressing mechanism 3 and the cutting mechanism 4 and has an opening facing the feeding mechanism 2.

[0023] The feeding mechanism 2 includes two vertically arranged and horizontally extending guide plates 21 in the same direction. The two guide plates 21 are respectively movably connected to both ends of a horizontal slide rail 22 through two connecting pieces 24, and the extending direction of the horizontal slide rail 22 is perpendicular to the two guide plates 21. Thus, the two guide plates 21 can slide along the horizontal slide rail 22 to adjust the distance between them.

[0024] Preferably, the horizontal slide rail 22 is installed on the machine table 1 through a mounting bracket 25.

[0025] In addition, a plurality of rotating rollers 23 are also arranged side by side on the machine table 1, and the extending directions of the rotating rollers 23 are the same as that of the horizontal slide rail 22, that is, their extending directions are perpendicular to the two guide plates 21. A plurality of arc-shaped notches 26 are arranged at the bottoms of the two guide plates 21, and the arc-shaped notches 26 are respectively stuck on the rotating rollers 23 from above. Thus, the stability of the two guide plates 21 can be ensured by arranging the rotating rollers 23.

[0026] The material pressing mechanism 3 includes two horizontally arranged pressing rollers 31 arranged up and down. Among them, the lower horizontal pressing roller 31 is in transmission connection with the rotor of a material pressing motor 32 through a transmission wheel 33 and a transmission belt 34, and the material pressing motor 32 is installed inside the machine table 1. Then, under the operation of the material pressing motor 32, the lower horizontal pressing roller 31 can be driven to rotate through the transmission wheel 33 and the transmission belt 34 to press the film material passing between the two horizontal pressing rollers 31.

[0027] The cutting mechanism 4 includes an upper cutting knife 41 and a lower cutting plate 42. The upper cutting knife 41 is located directly above the lower cutting plate 42 and the two can cooperate to cut the film material. Among them, the two bottom ends of the upper cutting knife 41 are respectively connected to the same lifting block 43 through two lifting rods 46, and an eccentric wheel 44 is movably installed in the middle of the lifting block 43. The eccentric wheel 44 is connected to the rotor of a cutting motor 45, and the cutting motor 45 is installed inside the machine table 1. Then, under the action of the cutting motor 45, the eccentric wheel 44 rotates to make the lifting block 43 rise and fall, and further drives the upper cutting knife 41 to rise and fall through the two lifting rods 46 to cooperate with the lower cutting plate 42 to cut the film material passing between the two.

[0028] Preferably, a stripping plate 5 is also installed on the machine table 1. The stripping plate 5 is located between the material pressing mechanism 3 and the cutting mechanism 4 and the cutting edge faces the material pressing mechanism 3.

[0029] When using this cutting machine, the tape carrying the film passes between two guiding plates 21 and is guided by the two guiding plates 21. The distance between the two guiding plates 21 can be adjusted according to the width of the tape. Then the tape passes between two horizontal pressure rollers 31 to press the film. Then the tape is peeled off by the peeling plate 5. Finally, the film passes between the upper cutting knife 41 and the lower cutting plate 42 and is thus cut off.

[0030] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
