Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figures 1-4 The cutting device for processing plastic packaging boxes includes a frame 1, a movable box 2, and a horizontal drive mechanism. A cutting mechanism 8 is arranged above the frame 1. The cutting mechanism 8 is used to cut plastic packaging boxes. The cutting mechanism 8 includes a blade, a motor, and a threaded rod. The blade is adjustable and driven by the motor to rotate and cut the plastic packaging box. Another motor drives the threaded rod to rotate and move the blade to the cutting position. The movable box 2 is arranged above the frame 1. A movable plate 6 is slidably connected to the inner wall of the movable box 2. A connecting rod 7 is slidably connected to the inner wall of the movable plate 6. A positioning plate 16 is slidably arranged outside the connecting rod 7. The horizontal drive mechanism is arranged outside the movable box 2 and is used to drive the positioning plate 16 to move. In specific use: when the cutting mechanism 8 is used to cut the plastic packaging box, when the movable box 2 drives the cutting mechanism 8 to descend, the horizontal drive mechanism drives the positioning plates 16 to move closer to each other until the positioning plates 16 fix the plastic packaging box. After the plastic packaging box is fixed, it is cut by the cutting mechanism 8 to prevent the plastic packaging box from shifting due to pressure.

[0029] In one aspect, the horizontal drive mechanism includes a first trapezoidal block 4 and a second trapezoidal block 5. The first trapezoidal block 4 is fixedly connected to the outer wall of the movable box 2, and the second trapezoidal block 5 is fixedly connected to the top of the connecting rod 7. A fixing block 12 is fixedly connected to the end of the connecting rod 7 away from the second trapezoidal block 5. An elastic component is provided between the movable box 2 and the connecting rod 7. The elastic component includes a square block 9 and a first circular rod 10. The square block 9 is slidably connected to the inner wall of the connecting rod 7, and the first circular rod 10 is fixedly connected to the outer wall of the square block 9. The square block 9 is slidably connected to the inner wall of the movable box 2. A first spring 11 is fixedly connected between the square block 9 and the movable box 2. The first trapezoidal block 4 and the second trapezoidal block 5 are both provided with parallel inclined surfaces, and the inclined surfaces are smooth. When the inclined surfaces of the first trapezoidal block 4 and the second trapezoidal block 5 abut against each other, the first trapezoidal block 4 can drive the second trapezoidal block 5 to move. The movable plate 6 is provided with an opening inside, and a sliding groove is provided inside the opening. The connecting rod 7 is slidably set with the sliding groove. At the same time, the first trapezoidal block 4 can move through the opening to prevent the movable plate 6 from conflicting with the first trapezoidal block 4.

[0030] On the other hand, an adjustment mechanism is provided on the outside of the fixing block 12. The adjustment mechanism includes a roller 13 and a second circular rod 14. The roller 13 is rotatably connected to the inner wall of the fixing block 12, and the second circular rod 14 is slidably sleeved on the inner wall of the fixing block 12. The positioning plate 16 is fixedly connected to the end of the second circular rod 14 away from the fixing block 12. A second spring 15 is movably sleeved on the outer wall of the second circular rod 14. The second spring 15 allows the positioning plate 16 to adapt to plastic packaging boxes of different sizes. At the same time, anti-slip pads are fixedly provided on the adjacent surfaces of the two positioning plates 16 to increase the clamping force of the positioning plates 16 on the plastic packaging boxes. The roller 13 is in contact with the surface of the frame 1 to make the positioning plate 16 more flexible and adaptable to the plastic packaging boxes. Positioning plate 16 moves smoothly. In actual use: during the movement of moving box 2, fixing block 12 drives roller 13 to move. Roller 13 abuts against the top of frame 1. Under the action of frame 1, fixing block 12 is fixed. Moving box 2 continues to move until second trapezoidal block 5 is in contact with first trapezoidal block 4. First trapezoidal block 4 drives second trapezoidal block 5 to move horizontally. Second trapezoidal block 5 drives positioning plate 16 to move through connecting rod 7. At the same time, connecting rod 7 squeezes first spring 11 until positioning plate 16 fixes plastic packaging box. When moving box 2 rises, first spring 11 resets and drives positioning plate 16 to reset, thus preventing plastic packaging box from shifting due to pressure.

[0031] In addition, there are two positioning plates 16 arranged horizontally and symmetrically. The cutting mechanism 8 is fixedly installed at the bottom of the moving box 2. The top of the frame 1 is fixedly connected to the driving component 3, which is used to drive the moving box 2 to move. An elastic component 17 is provided between the moving plate 6 and the moving box 2. The elastic component 17 includes a round rod and a spring. The elastic component 17 is used to make the moving plate 6 rotate and reset. The driving component 3 is adapted to a hydraulic cylinder.

[0032] In specific operation: During the movement of the movable box 2, the fixed block 12 drives the roller 13 to move. The roller 13 abuts against the top of the frame 1. Under the action of the frame 1, the fixed block 12 is fixed, and the movable box 2 continues to move until the second trapezoidal block 5 is in contact with the first trapezoidal block 4. The first trapezoidal block 4 drives the second trapezoidal block 5 to move horizontally. The second trapezoidal block 5 drives the positioning plate 16 to move through the connecting rod 7. At the same time, the connecting rod 7 squeezes the first spring 11 until the positioning plate 16 fixes the plastic packaging box. When the movable box 2 rises, the first spring 11 resets and drives the positioning plate 16 to reset, thereby preventing the plastic packaging box from shifting due to pressure.
