DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The above content of the present invention will be further described in detail through the following embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0026] Embodiment 1: Refer to Figure 1 , which is a schematic structural diagram of Embodiment 1 of the utility model. This embodiment discloses a residual film picking device, including a frame 3. The frame 3 is provided with a film lifting roller A 2, a film lifting roller B 5 and a film lifting roller C 8. The film lifting roller A 2 is located below, and the film lifting roller B 5 and the film lifting roller C 8 are located above the film lifting roller A 2. The film lifting roller B 5 is arranged in front of the film lifting roller A 2, and the film lifting roller C 8 is arranged behind the film lifting roller A 2. The height of the film lifting roller C 8 is higher than that of the film lifting roller B 5;

[0027] A film stripping roller 9 is provided on the film lifting roller C 8. The diameter of the film stripping roller 9 is larger than that of the film lifting roller C 8. A gap is left on the film stripping roller 9. A film lifting belt 7 is wound around the film lifting roller A 2, the film lifting roller B 5 and the film lifting roller C 8. The film lifting belt 7 can rotate with the three film lifting rollers as supports, that is, the film lifting belt 7 can pass through the gap of the film stripping roller 9. Hook teeth 6 for lifting the plastic film are fixed on the film lifting belt 7. The film lifting roller C 8 reciprocates on the frame through a profiling mechanism.

[0028] During actual use: The film-lifting roller C8 is a profiling wheel. The film-lifting belt is wound between the film-lifting roller A, the film-lifting roller B, and the film-lifting roller C. During the picking operation, the film-lifting belt rotates to pick up residual films. When the load increases, the film-lifting roller C can reciprocate on the frame through the profiling mechanism, enabling the film-lifting belt to have a profiling effect, avoiding the breakage of the film-lifting belt, and reducing the failure rate.

[0029] Since the film-lifting roller C8 is a profiling wheel and can move within a certain range, the film-lifting belt has a vibrating effect during operation, which can also remove impurities on some of the residual films, reducing the impurity content rate of the recycled residual films.

[0030] In addition, the film-lifting roller C8 is arranged at the rear, the film-lifting roller B5 is arranged at the front, and the film-lifting roller B5 is lower while the film-lifting roller C8 is higher. The residual film is driven by the film-lifting belt to move between the film-lifting roller B5 and the film-lifting roller C8 in an upward movement state. With the vibration of the film-lifting roller C8, some impurities can be removed during the upward movement process, achieving the effect of reducing the impurity content rate.

[0031] Embodiment 2: Compared with Embodiment 1, the difference in this embodiment is that: a profiling mechanism is provided, and the film-lifting roller C performs profiling through the profiling mechanism. The profiling mechanism includes a profiling track 10. A chute is provided on the profiling track 10, and the rotating shaft of the film-lifting roller C8 is arranged in this chute. And a buffer spring 21 is provided on the rotating shaft of the film-lifting roller C8, enabling the film-lifting roller C8 to move left and right in the chute of the profiling track 10.

[0032] Embodiment 3: Compared with Embodiment 2, the difference in this embodiment is that: the structure of the profiling mechanism is different. In this embodiment, the profiling mechanism includes a fixed arm 19 and a tension spring 20. One end of the fixed arm 19 is hinged to the frame 3, the film-lifting roller C8 is arranged at the other end of the fixed arm 19, and the tension spring 20 is arranged between the fixed arm 19 and the frame 3. The tension spring 20 pulls the film-lifting roller C8 in the direction of stretching the film-lifting belt 7.

[0033] Embodiment 4: Refer to Figure 2 , which is the structural schematic diagram of this Embodiment 4. Compared with Embodiment 1, the difference in this embodiment is that: the film-lifting roller B5 is arranged in front of the film-lifting roller A2, the film-lifting roller C8 is arranged behind the film-lifting roller A2, the height of the film-lifting roller C8 is higher than that of the film-lifting roller B5, and the film-lifting roller B5 is a driving wheel.

[0034] In this embodiment, the plastic film is lifted to the highest point by the film-lifting belt and then moves downward, and generates vibrations during the downward movement. During the picking operation, there is a downward movement process, which can also achieve the effect of removing impurities in the residual film and improving the residual film recycling effect.

[0035] In this embodiment, the film-lifting roller B5 is the driving wheel. The film-lifting belt on the left side of the film-lifting roller B5 is in the lifting state and is under tension, while the film-lifting belt on the right side is in the downward state and is in a relaxed state. Combining with the fact that the film-lifting roller C8 can perform profiling movement, the effect of picking up residual film can be improved and the removal of residual film impurities can be enhanced.

[0036] The tension state and the relaxed state are the states compared between the two states.

[0037] Embodiment 5: Refer to Figure 3 , which is the structural schematic diagram of this Embodiment 5.

The soil-removing wheel groove (9-1) is a circular groove on the circumferential surface of the film-removing roller (9). When small soil particles adhere to the residual film, when the residual film contacts the film-removing roller, the small soil particles can be discharged from the soil-removing wheel groove (9-1).

[0038] Embodiment 6: Compared with any one of Embodiments 1 to 5, the difference of this embodiment lies in that: at least one of the impurity-removing auger 1, the cleaning brush roller A13, the cleaning brush roller B14, the cleaning brush roller C15, and the cleaning brush roller D17 is provided on the frame 3.
