[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2In this embodiment, a plastic bottle cutting device comprises a mounting frame 1, a cutting wheel 4 and a driving member 12. A driving assembly 2 is fixed on the mounting frame 1. A connecting frame 3 is fixed to the outer side of the output shaft of the driving assembly 2 and is located in the mounting frame 1. A mounting member 5 is movably connected in the mounting frame 1. The driving member 12 is fixed in the mounting member 5. The cutting wheel 4 is fixed to the outer side of the output shaft of the driving member 12. Screws 10 are fixed to the front and back sides of the mounting member 5. One end of the screw 10 away from the mounting member 5 penetrates and extends to the outer side of the connecting frame 3. A nut 13 is threadedly connected to the outer side of the screw 10. The nut 13 abuts against the outer peripheral surface of the connecting frame 3. The nut 13 on the screw 10 is rotated to separate the nut 13 from the connecting frame 3, and the connecting frame 3 can release the locking of the mounting member 5. The nut 13 abuts against the connecting frame 3, and the connecting frame 3 can lock the mounting member 5.

[0021] The shape of the connecting frame 3 is U-shaped, the width of the mounting member 5 is adapted to the width of the inner cavity of the connecting frame 3, a through hole is provided on the connecting frame 3 for the screw 10 to pass through, and the mounting member 5 performs a circular motion with the screw 10 as the center. After the connecting frame 3 releases the lock on the mounting member 5, the driving member 12 and the cutting wheel 4 can rotate, so that the cutting wheel 4 can cut the plastic bottle in an inclined state.

[0022] See also Figure 3 In this embodiment, a positioning assembly is provided on the mounting member 5, and the positioning assembly includes an upper pressing plate 6 and two lower pressing plates 9. The lower pressing plate 9 is vertically fixed to the inner bottom wall of the mounting member 5, and the upper pressing plate 6 is slidably connected between the two lower pressing plates 9. The distance between the two lower pressing plates 9 is adapted to the width of the upper pressing plate 6.

[0023] A groove 11 is provided on both the upper pressing plate 6 and the lower pressing plate 9, and the groove 11 is a V-shaped groove. After the upper pressing plate 6 moves, the distance between the two grooves 11 on the upper pressing plate 6 and the lower pressing plate 9 increases, and the V-shaped groove 11 can adapt to plastic bottles of different sizes. The front and back sides of the upper pressing plate 6 are fixed with limit members 8, and the longitudinal section of the limit member 8 is U-shaped. A connecting rod 7 is vertically fixed to the inner bottom wall of the mounting frame 1 corresponding to the limit member 8. When the upper pressing plate 6 moves, the limit member 8 will also move outside the connecting rod 7 to limit the moving distance of the upper pressing plate 6, and the limit member 8 makes up and down linear motion on the outside of the connecting rod 7.

[0024] The working principle of the above embodiment is:

[0025] (1) When it is necessary to process the plastic bottle, first pull the upper pressing plate 6 upward. After the upper pressing plate 6 moves, the distance between the two grooves 11 on the upper pressing plate 6 and the lower pressing plate 9 increases. At this time, the plastic bottle can be placed between the two grooves 11. After the plastic bottle is placed, the plastic bottle can be fixed with the cooperation of the upper pressing plate 6 and the lower pressing plate 9. When the upper pressing plate 6 moves, the limiter 8 will also move outside the connecting rod 7 to limit the moving distance of the upper pressing plate 6.

[0026] (2) After the plastic bottle is positioned, the nut 13 on the screw 10 is rotated to separate the nut 13 from the connecting frame 3, and the connecting frame 3 can release the lock on the mounting member 5. The driving member 12 and the cutting wheel 4 can rotate around the screw 10 as the center of the circle, so that the cutting wheel 4 can cut the plastic bottle in an inclined state. At the same time, the reverse nut 13 makes the nut 13 abut against the connecting frame 3 to lock the cutting wheel 4. After the state of the cutting wheel 4 is adjusted, the operation of the driving assembly 2 can enable the cutting wheel 4 to cut the plastic bottle at an inclined state.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
