It should be noted that these embodiments do not represent all possible implementation manners of the utility model, and any person skilled in the art can obtain embodiments without creative labor, which are within the protection scope of the utility model.

[0029] The utility model aims at providing an arc-shaped blade film stripping device suitable for a pin-tooth type residual film recycling machine to solve the problems in the prior art, improve film stripping performance, improve maintenance convenience, and facilitate further recycling of residual films.

[0030] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be described in further detail below in combination with the drawings and specific implementation manners.

[0031] As shown in the drawings, Figures 1 to 7 The utility model provides an arc-shaped blade film stripping device suitable for a pin-tooth type residual film recycling machine, which comprises arc-shaped film stripping blades 1, film stripping rollers 2, support frames 3 and guide shells 4.

[0032] The utility model discloses a residual film of pin tooth type is recovered after the film picking operation of residual film recovery machine, and the residual film on the pin tooth is scraped and is transported.

[0033] In the embodiment, the arc-shaped stripping blade 1 comprises an arc-shaped stripping rubber blade support bottom plate 1-1, a stripping rubber blade 1-2, a stripping rubber blade fixing bolt and nut 1-3, and a stripping rubber blade pressing plate 1-4; the stripping drum 2 comprises a stripping drum center tube 2-1, a stripping drum center tube outer connecting plate 2-2, a stripping drum shaft head 2-3, and an arc-shaped stripping blade base plate 2-4; the arc-shaped stripping rubber blade support bottom plate 1-1 in the arc-shaped stripping blade 1 and the arc-shaped stripping blade base plate 2-4 in the stripping drum 2 are connected and fixed by the arc-shaped stripping blade fixing bolt and nut 6 and can be detached; one end of the arc-shaped stripping rubber blade support bottom plate 1-1 and the stripping rubber blade pressing plate 1-4 clamp one end of the stripping rubber blade 1-2 by the connection and fixation of the stripping rubber blade fixing bolt and nut 1-3, and the other end of the arc-shaped stripping rubber blade support bottom plate 1-1 is glued to the other end of the stripping rubber blade 1-2, so that the arc-shaped stripping rubber blade support bottom plate 1-1 and the stripping rubber blade 1-2 are fixed and arranged and can be detached.

[0034] The two ends of the stripping drum center tube 2-1 in the stripping drum 2 are fixed to the stripping drum center tube outer connecting plate 2-2, the stripping drum center tube outer connecting plate 2-2 is fixed to the stripping drum shaft head 2-3, and the stripping drum shaft heads 2-3 at the two ends of the stripping drum 2 are matched with the bearing seat 5. The membrane drum shaft head 2-3 can be driven to rotate, and the stripping drum 2 connected and integrated therewith rotates, so that the arc-shaped stripping blade base plate 2-4 uniformly arranged on the outer surface of the stripping drum center tube 2-1 in the stripping drum 2 rotates synchronously, and the arc-shaped stripping blade 1 arranged and connected therewith rotates.

[0035] The number of tooth-shaped gaps of the arc-shaped stripping rubber blade support bottom plate 1-1 and the stripping rubber blade 1-2 in the stripping blade 1 is consistent with the number of pin teeth on the film picking device of the pin tooth type residual film recovery machine, and the size of the tooth-shaped gap of the stripping rubber blade 1-2 is smaller than that of the tooth-shaped gap of the arc-shaped stripping rubber blade support bottom plate 1-1; when the stripping blade 1 rotates, the tooth-shaped gap is aligned with the pin tooth, so that the stripping rubber blade 1-2 with the smaller tooth-shaped gap can effectively contact and scrape the residual film on the pin tooth, and the arc-shaped design of the stripping blade 1 can better adapt to the shape and movement path of the pin tooth, thereby improving the stripping efficiency.

[0036] The support frame 3 comprises a vertical rectangular tube 3-1, a bearing seat support plate 3-2, and a reinforcing rib plate 3-3; the reinforcing rib plate 3-3 is symmetrically arranged on both sides of the vertical rectangular tube 3-1 and is fixedly connected to the rack of the pin-tooth residual film recycling machine; the bearing seat support plate 3-2 is fixedly connected to the upper end of the vertical rectangular tube 3-1 and is bolted with the bearing seat 5; the length of the vertical rectangular tube 3-1 and the position of the fixed connection to the rack of the pin-tooth residual film recycling machine are changed according to the installation position of the pin-tooth cylinder of the pin-tooth residual film recycling machine, so that the distance between the film stripping blade 1 and the pin-tooth is changed, and the contact and scraping of the film stripping rubber blade 1-2 in the film stripping blade 1 with the pin-tooth from the root to the top of the pin-tooth is ensured when the film stripping rubber blade 1-2 in the film stripping blade 1 rotates, thereby ensuring good film stripping effect.

[0037] The flow guide shell 4 is composed of a shell arc panel 4-1, a shell plane panel 4-2, and a flow guide shell support framework 4-3, and the shell arc panel 4-1 is a certain distance away from the film stripping cylinder 2 on which the film stripping blade 1 is arranged, so as to accommodate the full rotation of the film stripping cylinder 2 on which the film stripping blade 1 is arranged; the flow guide shell fixing bolts 4-4 connect and fix the shell arc panel 4-1, the shell plane panel 4-2, and the flow guide shell support framework 4-3, and can be disassembled and repaired; the flow guide shell 4 provides a good airflow chamber for the film stripping cylinder 2 and the film stripping blade 1, and when the film stripping blade 1 rotates, airflow is generated, thereby producing a conveying effect on the residual film on the pin-tooth of the pin-tooth residual film recycling machine film picking device.

[0038] The film stripping rubber blade 1-2 in the film stripping blade 1 effectively scrapes the residual film on the pin-tooth of the pin-tooth residual film recycling machine through mechanical contact. At the same time, due to the rotation of the film stripping blade 1, the airflow generated in the flow guide shell 4 further promotes the conveying of the residual film on the pin-tooth. The two effects work together to make the residual film fall off smoothly and be conveyed to the film collecting device of the pin-tooth residual film recycling machine, thereby ensuring the efficiency of the recycling process.
