DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0027] The core components of the residual film recycling machine include the residual film picking mechanism, the film stripping mechanism and the film collecting mechanism, among which the working effect of the film stripping mechanism directly determines the recovery rate and impurity rate of the residual film. At present, the telescopic rod-tooth type residual film recycling machine usually uses a rotating film stripping roller for film stripping. When the rod teeth move to the film stripping position, they will be completely retracted into the drum. At this time, the film stripping blades on the film stripping roller will scrape off the residual film carried by the rod teeth to complete the film stripping process. However, the working environment of the residual film recycling machine is complex, and the picked up residual film is often mixed with impurities such as soil and straw. In the film stripping process of the existing telescopic rod-tooth type residual film recycling machine, the film stripping roller is easily blocked by soil or straw, affecting the film stripping efficiency.

[0028] In view of the above reasons, an embodiment of the present application provides a film stripping mechanism for a residual film recycling machine, which reduces the risk of the film stripping roller 200 being blocked by soil and straw and improves the film stripping efficiency.

[0029] like Figure 1 and Figure 2 As shown, the film stripping mechanism of the residual film recycling machine provided in the embodiment of the present application includes a supporting mechanism 100 , a film stripping roller 200 and a film stripping blade 300 .

[0030] The two supporting mechanisms 100 are arranged at intervals to support the stripping roller 200 for rotation. The two ends of the stripping roller 200 are rotatably connected to the two supporting mechanisms 100. The stripping blade 300 extends along the central axis of the stripping roller 200, and the stripping blade 300 is connected to the outer circumferential surface of the stripping roller 200. Figure 4 and Figure 5 The film stripping blade 300 is provided with an outwardly facing toothed structure 310, and the film stripping blade 300 is provided with a plurality of filtering holes 320 along its length direction.

[0031] The toothed structure 310 on the film stripping blade 300 can effectively separate the residual film from impurities such as soil and straw, and transport the residual film to the film collecting box 600; the filter holes 320 and multiple filter holes 320 on the film stripping blade 300 allow impurities such as soil and straw to pass through during the film stripping process, thereby reducing the risk of the film stripping roller 200 being blocked and improving the film stripping efficiency.

[0032] like Figure 4 and Figure 5 As shown, the tooth structure 310 in the embodiment of the present application includes a plurality of demolding teeth. The plurality of demolding teeth are arranged in a linear array along the length direction of the demolding blade 300, and each demolding tooth includes a first tooth surface 311 and a second tooth surface 312. The first tooth surface 311 and the second tooth surface 312 are connected to form an angle convex to the outside, and an obtuse angle is formed between the first tooth surface 311 and the second tooth surface 312.

[0033] An obtuse angle is formed between the first tooth surface 311 and the second tooth surface 312 of the stripping tooth, which can reduce the possibility of the stripping tooth tearing the residual film, so that the stripping tooth can separate the residual film from impurities while maintaining the integrity of the residual film, thereby facilitating the collection of the residual film.

[0034] Exemplarily, the first tooth surface 311 and the second tooth surface 312 are connected and form an angle of 120°.

[0035] Continue to refer to Figure 4 and Figure 5 As shown, the filter hole 320 is in the shape of an elongated strip, and the length direction of the filter hole 320 is perpendicular to the length direction of the film stripping blade 300 .

[0036] Compared with the round hole, the elongated filter hole 320 has a larger area. During the film stripping process, the elongated filter hole 320 allows dirt, straw and other impurities to pass smoothly, reducing the possibility of the filter hole 320 being blocked.

[0037] Specifically, each long strip-shaped filter hole 320 is located below the first tooth surface 311 and the second tooth surface 312 of each demolding tooth, thereby achieving a relatively long filter hole 320 in a limited space to ensure that impurities such as soil and straw can be filtered out as much as possible.

[0038] like Figure 3 As shown, the film stripping roller 200 provided in the embodiment of the present application includes a roller 210 , a fixing plate 220 , a connecting assembly 230 and a rotating shaft 240 .

[0039] The fixing plate 220 is connected to the outer cylindrical surface of the roller 210. Specifically, in some embodiments of the present application, the fixing plate 220 is welded to the outer cylindrical surface of the roller 210. In other embodiments of the present application, the fixing plate 220 and the outer cylindrical surface of the roller 210 can also be connected by bonding, riveting, etc.

[0040] The fixing plate 220 is detachably connected to the stripping blade 300. Specifically, Figure 3 As shown, the fixing plate 220 is provided with a plurality of first through holes 221. Figure 4 As shown, a plurality of second through holes 330 are provided on the stripping blade 300; when the stripping blade 300 is connected to the roller 210, the plurality of first through holes 221 on the fixing plate 220 are matched one by one with the plurality of second through holes 330 on the stripping blade 300, bolts are passed through the first through holes 221 and the second through holes 330, and nuts are used to tighten them, thereby realizing a detachable connection between the stripping blade 300 and the fixing plate 220.

[0041] When the stripping blade 300 is used for a long time and the toothed structure on the stripping blade 300 is worn, the worn stripping blade 300 can be removed from the fixing plate 220 and a new stripping blade 300 can be connected to the fixing plate 220 .

[0042] The connecting assembly 230 is located inside the roller 210, and the connecting assembly 230 is connected to the inner wall of the roller 210. Specifically, the connecting assembly 230 is fixedly connected to the inner wall of the roller 210 by welding, bonding, or other connection methods. One end of the rotating shaft 240 extends into the roller 210 and is fixedly connected to the connecting assembly 230, and the other end of the rotating shaft 240 is rotatably connected to the supporting mechanism 100, so that the rotating shaft 240 can drive the roller 210 to rotate through the connecting assembly 230, thereby realizing the film stripping work.

[0043] The embodiment of the present application provides a specific structure of the connection component 230, such as Figure 3As shown, the connecting assembly 230 includes a first spoke plate 231 and a second spoke plate 232. The first spoke plate 231 and the second spoke plate 232 are arranged at intervals and are both connected to the inner wall of the roller 210. The end of the rotating shaft 240 extending into the roller 210 is connected to the first spoke plate 231 and the second spoke plate 232.

[0044] Specifically, the first spoke plate 231 and the second spoke plate 232 are both connected to the inner wall of the roller 210 by welding. The second spoke plate 232 is close to the end of the roller 210. When the second spoke plate 232 is connected to the roller 210, the second spoke plate 232 is directly welded to the roller 210 through the end opening of the roller 210. The first spoke plate 231 is located on the side of the second spoke plate 232 away from the support mechanism 100. The outer circumferential surface of the roller 210 is provided with a plug welding hole 211. When the first spoke plate 231 is connected to the roller 210, the first spoke plate 231 is welded to the roller 210 through the plug welding hole 211.

[0045] In some other embodiments of the present application, the first spoke plate 231 and the roller 210 , as well as the second spoke plate 232 and the roller 210 , may be connected by riveting, bonding, or the like.

[0046] exist Figure 3 In the specific structure of the connecting assembly 230 shown, the first spoke plate 231 and the second spoke plate 232 fix the end of the rotating shaft 240 that penetrates into the roller 210, so that the rotating shaft 240 can drive the roller 210 to rotate through the first spoke plate 231 and the second spoke plate 232.

[0047] like Figure 3 As shown, the embodiment of the present application provides a specific structure of the support mechanism 100. The support mechanism 100 includes a frame plate 110, a bearing seat 120 and a bearing 130. The bearing seat 120 is connected to the frame plate 110. The bearing 130 is installed in the bearing seat 120 and connected to the rotating shaft 240.

[0048] The bearing 130 supports the rotating shaft 240, so that the rotating shaft 240 can rotate smoothly. The frame plate 110 is used to connect with other structures of the film stripping machine.

[0049] Specifically, Figure 3 The bearing seat 120 shown is connected to the frame plate 110 by bolts and nuts. Of course, the bearing seat 120 can also be connected to the frame plate 110 by other connection methods such as welding and bonding.

[0050] In order to prevent the residual film from winding around the rotating shaft 240 and affecting the normal film stripping work, continue to refer to Figure 3As shown, the film stripping mechanism of the residual film recycling machine provided in the embodiment of the present application also includes two anti-entanglement mechanisms 400 , which are respectively connected to the two ends of the film stripping roller 200 and are configured to prevent the residual film from winding around the rotating shaft 240 .

[0051] like Figure 3 As shown, the embodiment of the present application provides a specific structure of an anti-entanglement mechanism 400. The anti-entanglement mechanism 400 includes a guard plate 430, and a first anti-entanglement ring 410 and a second anti-entanglement ring 420 surrounding the bearing 130. The guard plate 430 is connected to the end surface of the film stripping roller 200, the inner wall of the first anti-entanglement ring 410 is connected to the outer edge of the guard plate 430, and the outer circumferential surface of the first anti-entanglement ring 410 is higher than or flush with the outer edge of the film stripping blade 300. The second anti-entanglement ring 420 is located on the inner side of the first anti-entanglement ring 410, and is connected to the side of the frame plate 110 facing the guard plate 430.

[0052] The guard plate 430, the first anti-entanglement ring 410 and the second anti-entanglement ring 420 work together to prevent residual film from entering the gap between the roller 210 and the supporting mechanism 100. The guard plate 430 can prevent the residual film on the stripping roller 200 and the stripping blade 300 from moving in the direction of the frame plate 110. When a small amount of residual film bypasses the guard plate 430, the first anti-entanglement ring 410 and the second anti-entanglement ring 420 located outside the bearing 130 can further block the residual film, preventing the residual film from entering the gap between the roller 210 and the supporting mechanism 100, thereby preventing the residual film from winding around the rotating shaft 240.

[0053] like Figure 3 As shown, the residual film recycling machine further includes a transmission wheel 500, and the transmission wheel 500 is installed on one of the rotating shafts 240. The transmission wheel 500 can be a structure capable of transmitting power, such as a pulley, a sprocket, and a gear.

[0054] Figure 6 The residual film recovery principle diagram provided in the embodiment of the present application is as follows: Figure 6 The working process of the film stripping mechanism of the residual film recovery machine provided in the embodiment of the present application is described.

[0055] The residual film picking mechanism 700 rotates to pick up the residual film in the soil. The picked-up residual film is mixed with impurities such as soil and straw. Driven by the rotation of the residual film picking mechanism 700, the picked-up residual film is sent to the film stripping mechanism of the residual film recovery machine provided in the embodiment of the present application. The film stripping roller 200 rotates, and the film stripping blade 300 installed on the film stripping roller 200 performs the film stripping work. The toothed structure 310 on the film stripping blade 300 separates the residual film from impurities such as soil and straw. Impurities such as soil and straw fall onto the ground through the filter holes 320 on the film stripping blade 300. The separated residual film is sent to the film collecting box 600 as the residual film blade 300 rotates.

Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
