Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figs. 1-4 As shown, this embodiment proposes a film-forming device with a detachable scraper, including two symmetrically arranged connecting plates 9 and a nail tooth fixing plate 11. The two connecting plates 9 are connected together by screws to a mounting plate 10. The two connecting plates 9 are rotatably mounted with a drive shaft 1, an eccentric shaft 2 and a driven shaft 3. The drive shaft 1 and the eccentric shaft 2 are connected together by a synchronous pulley and a synchronous belt 13 is provided. The eccentric shaft 2 and the driven shaft 3 are connected together by a synchronous pulley and a synchronous belt 12 is provided.

[0028] Several film-forming chains 6 arranged in a rectangular array are fitted together on the outer circumferential surfaces of the drive shaft 1, the eccentric shaft 2, and the driven shaft 3. Several film-forming teeth 7 arranged in a rectangular array are welded to the outer surface of the film-forming chains 6.

[0029] An eccentric wheel 5 is fixedly sleeved on the outer circumferential surface of the eccentric shaft 2, and several stripping discs 4 are evenly distributed in a rectangular array on the outer circumferential surface of the drive shaft 1. The stripping discs 4 and the film-raising teeth 7 are distributed in a cross pattern.

[0030] A number of nail-tooth scraper plates 8 arranged in a rectangular array are fixedly connected to one side of the nail-tooth fixing plate 11 by screws. The nail-tooth scraper plates 8 and the film-forming teeth 7 correspond one-to-one.

[0031] like Figs. 1-4As shown, the inside of the mounting plate 10 is provided with a sliding groove, the inside of the sliding groove is slidably connected with a sliding block 15, one side of the sliding block 15 is fixedly connected with a pull handle 14, the inside of the mounting plate 10 is provided with a limiting groove in communication with the sliding groove, the pull handle 14 is slidably connected in the inside of the limiting groove, the sliding block 15 and the sliding groove are commonly welded with a connecting spring;

[0032] The top of the sliding block 15 is inclined, and the sliding block 15 with an inclined top can be automatically retracted into the sliding groove under pressure during installation, thereby simplifying the installation process.

[0033] As shown, Figs. 1-4 The inside of the mounting plate 10 is provided with a mounting groove, the mounting groove and the nail tooth fixing plate 11 are the same in shape and size, and the mounting groove is appropriately arranged to ensure that the nail tooth mud scraping plate 8 can achieve precise cleaning effect during the cleaning process of the film forming tooth 7. The inside of the nail tooth fixing plate 11 is provided with a fixing groove, the sliding block 15 is slidably connected in the inside of the fixing groove, and the nail tooth mud scraping plate 8 is made of cloth-pressed rubber material. The material of the nail tooth mud scraping plate 8 is changed to cloth-pressed rubber, which can greatly reduce the sound generated when the nail tooth fixing plate 11 and the film forming tooth 7 are in contact.

[0034] In this embodiment, when using the device to form a film, first, the connecting plate 9 is fixed to the front end of the film removing machine, the driving shaft 1 is connected to the power through the synchronous belt, one end of the mulch film is lifted, and the film is sequentially passed through the driven shaft 3, the eccentric shaft 5 and finally the film removing disc 4 to enter the ready mulch film processing equipment;
