Description

Technical Field

[0001] This utility model belongs to the field of residual film recycling technology, and in particular relates to a belt-type residual film combing and picking mechanism and the residual film picking machine composed thereof. Background Technology

[0002] Xinjiang, as my country's largest cotton production base, has long relied on plastic film mulching technology to increase temperature and retain moisture. However, the accumulation of residual film has led to serious "white pollution." Traditional residual film recycling machines usually use toothed or spring-toothed rollers to pick up and collect the residual film. However, there are the following technical bottlenecks in the film removal process: the toothed rollers are easily entangled by the residual film. In particular, the residual film in Xinjiang cotton fields is highly adhesive after aging and breaking, requiring frequent machine shutdowns for cleaning. This results in poor operational continuity and restricts recycling efficiency and practicality. This technical dilemma makes the development of new processing technologies urgent.

[0003] Based on the above problems, the utility model patent with authorization announcement number CN221986811 U discloses a plastic film recycling and baling device and a plastic film recycling and baling machine thereof, which discloses a scheme of using a belt for film removal. According to paragraphs

[0058] -

[0061] of the specification and the appendix to the specification... Figure 4 -7 shows that in this structure, the film-forming groove belt roller and the film-removing deep groove belt roller are arranged opposite each other in the horizontal direction. At the same time, a separate secondary film-removing roller is added below the film-removing deep groove belt roller. This structure can achieve the purpose of film removal by belt in two stages, but it also has some shortcomings: (1) The structure is complicated and requires the film-forming roller, the film-forming groove belt roller, the film-removing deep groove belt roller and the secondary film-removing roller to work together to achieve this; (2) The film-forming groove belt roller and the film-removing deep groove belt roller are arranged opposite each other in the horizontal direction, which increases the volume.

[0004] Based on the above shortcomings, this solution provides a belt-type residual film combing and picking mechanism and the residual film picking machine composed thereof. Utility Model Content

[0005] This utility model provides a belt-type residual film combing and picking mechanism and a residual film picking machine composed thereof. The picking mechanism has a simple and compact structure, and at the same time, it has a good film removal effect, thus solving at least one deficiency of the prior art.

[0006] This application provides a belt-type residual film combing and picking mechanism, including a first toothed belt shaft, a second toothed belt shaft, a film removal shaft, a film removal belt, and belt teeth. The first toothed belt shaft, the second toothed belt shaft, and the film removal shaft are distributed in an obtuse triangle on the same plane. The first toothed belt shaft and the second toothed belt shaft are distributed vertically. The belt teeth are wound around the first toothed belt shaft and the second toothed belt shaft at equal intervals. The film removal belt is wound around the first toothed belt shaft, the second toothed belt shaft, and the film removal shaft and is located between two adjacent belt teeth.

[0007] As a preferred embodiment of this application, it further includes a debris removal auger, which is disposed between the first toothed belt shaft and the second toothed belt shaft and is arranged parallel to the first toothed belt shaft and the second toothed belt shaft, in order to receive impurities that fall onto the second toothed belt shaft due to gravity.

[0008] As a preferred embodiment of this application: the debris removal auger is located on the side of the second toothed belt shaft and is fixed to the second toothed belt shaft by a fixing bracket.

[0009] As a preferred embodiment of this application: the first toothed belt shaft and the second toothed belt shaft have the same structure. At the same time, the first toothed belt shaft, the second toothed belt shaft and the demolding shaft are respectively provided with demolding belt grooves arranged at equal intervals, and the spacing between two adjacent demolding belt grooves is adapted to the belt teeth.

[0010] As a preferred embodiment of this application: the stripping shaft is located to the right of the first toothed belt shaft and the second toothed belt shaft, and the pickup assembly composed of the first toothed belt shaft, the second toothed belt shaft and the belt teeth is inclined at 10-30° toward the stripping shaft side.

[0011] As a preferred embodiment of this application, the diameter of the stripping shaft is smaller than the diameter of the first toothed belt shaft and the second toothed belt shaft.

[0012] This solution also provides a residual film picking machine, including a frame, on which the belt-type residual film combing and picking mechanism described in any of the above claims is provided.

[0013] Compared with existing technologies, the advantages of this belt-type residual film combing and picking mechanism are:

[0014] The first and second toothed belt shafts simultaneously serve as the drive shafts for both the belt teeth and the stripping belt. The stripping shaft is positioned on one side of both shafts, forming an obtuse triangle on the same plane. This stripping shaft acts as both the tension and limiting shaft for the stripping belt, ensuring that the stripping belt and the belt teeth wound around the first and second toothed belt shafts respectively form primary and secondary stripping points. This allows for two stripping processes on the belt teeth. Compared to existing technologies, this solution achieves multiple stripping effects through the coordinated operation of three shafts, eliminating the need for additional... The secondary stripping shaft reduces the design cost of the picking mechanism and simplifies its structural complexity. Furthermore, this solution incorporates a debris-removing auger between the first and second toothed belt shafts to catch impurities that fall onto the second toothed belt shaft under gravity during the upward movement of the picked-up debris by the belt teeth. This prevents the stripping belt from breaking due to debris accumulation between the belt and the second toothed belt shaft. Therefore, this solution represents an improvement over existing technologies. The improved stripping and picking mechanism is simple, compact, and provides excellent stripping performance.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0024] Example 1:

[0025] like Figure 1As shown, this embodiment provides a belt-type residual film combing and picking mechanism. This solution is an improvement upon existing technology, addressing its shortcomings. Specifically, the picking mechanism includes a first toothed belt shaft 10, a second toothed belt shaft 11, a film removal shaft 13, a film removal belt 14, and belt teeth 15. The first toothed belt shaft 10, the second toothed belt shaft 11, and the film removal shaft 13 are arranged in an obtuse-angled triangle on the same plane. The first toothed belt shaft 10 and the second toothed belt shaft 11 are positioned vertically, and the film removal shaft 13 is located to the right of the first toothed belt shaft 10 and the second toothed belt shaft 11. The first toothed belt shaft 10 is located diagonally above the second toothed belt shaft 11; that is, the line connecting the first toothed belt shaft 10 and the second toothed belt shaft 11 is inclined towards the film removal shaft 13, specifically by an inclination of 10-30°. The belt teeth 15 include a belt 151 and spike teeth 152. The spike teeth 152 are preferably fixed to the belt 151 by screws. Figure 3 As shown, the belt teeth 15 are wound at equal intervals around the first toothed belt shaft 10 and the second toothed belt shaft 11. The demolding belt 14 is wound around the first toothed belt shaft 10, the second toothed belt shaft 11, and the demolding shaft 13 and is located between adjacent belt teeth 15, as shown. Figure 1-2 As shown; in order to better achieve demolding, it is preferable that the width of the demolding belt 14 is greater than the width of the belt 151 on the belt teeth 15; in addition, it is understood that a gap of 2-4mm is maintained between the demolding belt 14 and the belt teeth 15 to avoid hard friction between the demolding belt 14 and the belt teeth 15.

[0026] Specifically, in this embodiment, the first toothed belt shaft 10 and the second toothed belt shaft 11 simultaneously serve as the drive shafts for the belt teeth 15 and the stripping belt 14. The stripping shaft 13 is positioned on one side of the first toothed belt shaft 10 and the second toothed belt shaft 11, forming an obtuse triangle on the same plane. The stripping shaft 13 serves as the tensioning shaft and limiting shaft for the stripping belt 14, causing the stripping belt 14 and the belt teeth 15 wound on the first and second toothed belt shafts 10 and 11 to respectively form a primary stripping point and a secondary stripping point. That is, during the clockwise rotation of the belt teeth 15, they will successively compare with the stripping belt 14 at the primary and secondary stripping points, thus stripping the belt teeth 15 twice. Compared to existing technologies, this solution can achieve multiple stripping effects with the coordinated cooperation of a limited number of shafts, eliminating the need for an additional secondary stripping shaft 13, reducing the design cost of the picking mechanism, and simplifying the complexity of the picking mechanism's design structure. Furthermore, according to Figure 1It can be seen that when the obtuse-angled triangular structure formed by the first toothed belt shaft 10, the second toothed belt shaft 11 and the demolding shaft 13 is running, since there is an angle of 35-55° between the running direction of the belt teeth 15 and the running direction of the demolding belt 14, each nail tooth 152 can completely pass through the demolding belt 14 during the running of the belt teeth 15, thereby peeling off the residual film on each nail tooth 152, achieving effective and efficient demolding.

[0027] Understandably, in this embodiment, the lengths of the first toothed belt shaft 10, the second toothed belt shaft 11, and the demolding shaft 13 can be determined according to the width of the frame. This embodiment does not limit this length. In actual installation, the first toothed belt shaft 10, the second toothed belt shaft 11, and the demolding shaft 13 are respectively mounted on the frame through corresponding bearing seats.

[0028] As a preferred embodiment, the picking mechanism further includes a debris removal auger 16. It should be noted that the debris removal auger 16 in this embodiment is not a traditional debris removal mechanism on a picking machine. The transmission debris removal mechanism is usually located on one side of the picking mechanism to receive the fallen residual film. However, in this embodiment, the debris removal auger 16 is located between the first toothed belt shaft 10 and the second toothed belt shaft 11, and is arranged parallel to the first toothed belt shaft 10 and the second toothed belt shaft 11. It is used to receive impurities that fall onto the second toothed belt shaft 11 under gravity during the process of the belt teeth 15 moving the picked debris upwards. This avoids the phenomenon of the demolding belt 151 breaking due to the accumulation of impurities between it and the second toothed belt shaft 11. It can be seen that the debris removal auger 16 in this embodiment mainly serves the purpose of receiving impurities. Moreover, the impurities received are those that fall naturally due to gravity or fall onto the second toothed belt shaft 11 during the demolding process, rather than residual film. This effectively improves the service life of the belt teeth 15 and ensures the normal operation of the picking mechanism.

[0029] In this embodiment, the auger 16 is a conventional auger structure, that is, it includes a housing and a spiral shaft, such as... Figure 4 As shown, the spiral shaft is installed inside the casing. After impurities fall into the inner cavity of the casing, they are moved by the rotation of the spiral shaft.

[0030] In this embodiment, the auger 16 is located on the side of the second toothed belt shaft 11 and is fixed on the second toothed belt shaft 11 by the fixing bracket 17. That is, the auger 16 is mounted above the second toothed belt shaft 11 by the fixing bracket 17. It can be understood that the fixing bracket 17 can be a plate-shaped structure or a rod-shaped structure. The fixing bracket 17 is welded to both sides of the second toothed belt shaft 11 and the auger 16.

[0031] In this embodiment, the first toothed belt shaft 10 and the second toothed belt shaft 11 have the same structure. Meanwhile, the first toothed belt shaft 10, the second toothed belt shaft 11, and the demolding shaft 13 are respectively provided with equally spaced demolding belt grooves 18, and the spacing between adjacent demolding belt grooves 18 is adapted to the belt teeth 15; for example... Figure 5-6 As shown, during use, the stripping belt 14 is engaged in the stripping belt groove 18 to limit the stripping belt 14. The belt teeth 15 are wound around the first toothed belt shaft 10 and the second toothed belt shaft 11 and located between two adjacent stripping belts 14. The stripping belt 14 limits the belt teeth 15. The above is a preferred installation structure of the belt teeth 15 and the stripping belt 14 in this embodiment. In other specific embodiments of this embodiment, the first toothed belt shaft 10, the second toothed belt shaft 11 and the stripping shaft 13 may also be provided with corresponding stripping belt grooves 18 and belt teeth 15 grooves, and the stripping belt 14 and belt teeth 15 may be engaged in the corresponding grooves.

[0032] In this embodiment, the diameter of the stripping shaft 13 is smaller than that of the first toothed belt shaft 10 and the second toothed belt shaft 11. The purpose of this design is to ensure that the picking assembly composed of the first toothed belt shaft 10, the second toothed belt shaft 11 and the belt teeth 15 can properly pick up the residual film and improve its strength.

[0033] Example 2:

[0034] This embodiment also provides a residual film picking machine, including a frame on which the belt-type residual film combing and picking mechanism described in Embodiment 1 is provided. The first toothed belt shaft 10, the second toothed belt shaft 11 and the film stripping shaft 13 are respectively mounted on the frame through corresponding bearing seats, thereby realizing the fixation of the picking mechanism on the frame.

[0035] In practical use: A tractor is used as the traction mechanism. The drive universal joint on the tractor provides power to the belt-type residual film combing and picking mechanism. The drive universal joint is connected to the first toothed belt shaft 10 through a transmission belt, thereby driving the first toothed belt shaft 10 to rotate. This, in turn, drives the belt teeth 15, the demolding belt 14, the second toothed belt shaft 11, and the demolding shaft 13 to rotate synchronously clockwise. During the rotation, the belt teeth 15 pick up the residual film and convey it to the position of the second toothed belt shaft 11, where it makes its first contact with the demolding belt 14. The demolding belt 14 then peels off the residual film from each tooth 152. As the belt teeth 15 continue to rotate, they will re-enter the position of the first toothed belt shaft 10. At the front end of this position, they will make secondary contact with the demolding belt 14, thereby achieving secondary peeling of the residual film on each nail tooth 152. The peeled residual film falls to the corresponding position for recycling. At the same time, since the belt residual film combing and picking mechanism is set at an inclination relative to the frame, the impurities that fall onto the second toothed belt shaft 11 under gravity will be received by the impurity discharge auger 16 and pushed to the outside. When the belt teeth 15 run to the bottom of the first toothed belt shaft 10, the residual film picking operation is performed again. The above steps are repeated until the mulch film is picked up.
