[0030] Grooves 20 are respectively arranged on the opposite surfaces of the two side panels 2 , a slide module 8 is arranged inside the groove 20 , and two sorting components 7 are respectively arranged on the slides of the corresponding slide modules 8 .

[0031] In the embodiment of the utility model, the cut plastic film can be clamped by the sorting component 7, and the plastic film is transported to the same position by the slide module 8 and then released, so that the messy plastic film can be neatly arranged.

[0032] In one embodiment of the present invention, Figure 2 As shown, the stretching assembly 4 may include a support shaft 40, a frame 41 and a stretching roller 42, wherein both ends of the support shaft 40 are respectively connected to the two side plates 2, the frame 41 is rotatably connected to the support shaft 40, and the stretching roller 42 is rotatably arranged inside the frame 41.

[0033] In an embodiment of the utility model, when the frame 41 is not subjected to any external force, under the action of gravity, one side of the frame 41 will overlap the upper surface of the base plate 1, and the plastic film on the film roller 11 will pass under the stretching roller 42 and be stretched by the weight of the frame 41 itself, so that it can be conveyed more smoothly.

[0035] It should be noted that the two ends of the knife holder 50 described in this embodiment pass through two slide grooves 21 respectively, and a cutting groove 120 is provided on the upper surface of the support plate 12 , and the cutting groove 120 is located directly below the cutting knife 51 .

[0036] Furthermore, if Figure 1 As shown, the driving assembly 6 may include a turntable 60 and a rotating rod 61, wherein the turntable 60 is rotatably disposed on the outer side wall of the side plate 2, one end of the rotating rod 61 is eccentrically hinged to the turntable 60, and the other end of the rotating rod 61 is hinged to the knife seat 50.

[0037] It should be noted that the turntable 60 described in this embodiment is connected to an external driving mechanism, wherein the external driving mechanism may be a motor, which can drive the turntable 60 to rotate, and drive the knife holder 50 to move up and down through the cooperation of the rotating rod 61, thereby intermittently cutting the plastic film.

[0038] In one embodiment of the present invention, Figure 3 As shown, the sorting component 7 may include a fixed plate 70, a rotating shaft 71, a rotating plate 72, a plurality of springs 73, two clamping plates 74 and two electromagnetic blocks 75, wherein the fixed plate 70 is installed on the slide of the slide module 8, one end of the rotating shaft 71 is rotatably connected to the fixed plate 70, the rotating plate 72 is arranged on the rotating shaft 71, a plurality of springs 73 are respectively arranged on the opposite surfaces of the rotating plate 72 and the fixed plate 70, two clamping plates 74 are oppositely arranged between the fixed plate 70 and the rotating plate 72, and the clamping plates 74 are connected to the springs 73, and two electromagnetic blocks 75 are respectively embedded and installed on the opposite surfaces of the two clamping plates 74.

[0039] It should be noted that two notches are provided on the side wall of the support plate 12 , and the two sorting components 7 are respectively arranged corresponding to the two notches, and when the spring 73 is in a natural state, the two clamping plates 74 are respectively located above and below the support plate 12 .

[0040] In the embodiment of the present invention, the two electromagnetic blocks 75 will generate magnetic attraction after being energized, attracting each other, thereby driving the two clamping plates 74 to approach each other to clamp the cut plastic film.

[0041] Furthermore, if Figure 2 and Figure 3 As shown, a gear 9 is provided on the rotating shaft 71 , and a toothed plate 13 is provided at the end of the side plate 2 adjacent to the side plate 2 , and the toothed plate 13 meshes with the gear 9 .

[0042] In the embodiment of the present invention, when the gear 9 moves to engage with the toothed plate 13 , the gear 9 drives the rotating shaft 71 to rotate 90 degrees due to the restriction of the toothed plate 13 , so that the rotating plate 72 is parallel to the side plate 2 .

[0043] Specifically, when cutting the plastic film, the relevant personnel place the film roller 11 on two brackets 10, and pass one end of the plastic film wrapped on the film roller 11 through between the two conveying rollers 3, under the stretching roller 42 and under the guide roller in sequence, and the plastic film can be transported toward the cutting component 5 through the two conveying rollers 3.

[0044] When the plastic film passes under the cutting knife 51, the relevant personnel controls the turntable 60 to rotate, and drives the knife holder 50 and the cutting knife 51 to move up and down through the cooperation of the rotating rod 61. When the cutting knife 51 moves downward, the plastic film can be cut.

[0045] The cut plastic film will fall between the two clamping plates 74. At this time, the relevant personnel control the two electromagnetic blocks 75 to be energized. The energized electromagnetic blocks 75 have magnetic attraction and drive the two clamping plates 74 to approach each other to clamp the plastic film. Then the relevant personnel control the slide module 8 to start, and the slide module 8 drives the two sorting components 7 and the cut plastic film to move forward. When the cut plastic film is separated from the support plate 12, the relevant personnel control the two electromagnetic blocks 75 to be powered off. At this time, the gear 9 moves to the position of the tooth plate 13. Due to the restriction of the tooth plate 13, the gear 9 rotates 90 degrees and drives the rotating plate 72 and the clamping plate 74 to rotate 90 degrees. The plastic film between the two clamping plates 74 will fall into the supporting frame 14, and then the sorting component 7 is driven to reset through the slide module 8, and the next cut plastic film is sorted.

[0046] In summary, the plastic film cutting device of the embodiment of the utility model can sort out the cut long plastic films and place them neatly, thereby reducing the workload of workers and improving the cutting efficiency of the plastic films.
