Description

Technical Field

[0001] This utility model relates to the field of film winding technology, and in particular to a winding device for fully biodegradable films. Background Technology

[0002] Fully biodegradable films typically refer to films made primarily from biodegradable materials. These films can be "degraded" in nature by microorganisms, with the final products being carbon dioxide and water, causing no pollution to the environment.

[0003] Patent application number 202122673337.7 discloses a winding device for biodegradable films, including a winding drum, with fixed shafts fixedly connected to the left and right ends of the winding drum, and movable blocks movably connected to the left and right ends of the winding drum, with locking rods movably connected inside the movable blocks.

[0004] However, in traditional winding devices used for fully biodegradable films, the film tail end on the winding roller is not fixed when the film is cut. The originally balanced tension may become unbalanced due to the loss of constraint at one end, causing the film to unravel and affecting subsequent work.

[0005] For example, in traditional fully biodegradable film winding equipment, if the film reaches the predetermined length during the winding process or needs to be cut, the operator usually pauses the winding machine and uses a knife or laser cutter to cut the film. During this process, if the end of the film is not properly secured, the tension that was originally balanced on the winding roller may suddenly become unbalanced due to the loss of one end's constraint, resulting in the film curling, wrinkling, or directly unraveling, affecting subsequent work. Utility Model Content

[0006] This utility model discloses a winding device for fully biodegradable films, which aims to solve the technical problem that when the film is being cut, the tail end of the film on the winding roller is not fixed, and the originally balanced tension may become unbalanced due to the loss of constraint at one end, causing the film to unravel and affecting subsequent work.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A winding apparatus for fully biodegradable films includes a frame, guide rollers, winding rollers, and a conveying assembly, and further includes:

[0009] Cutting mechanism: The cutting mechanism is disposed on the inner wall of the opposite side of the frame;

[0010] Fixing Mechanism: The fixing mechanism is installed on the inner wall of opposite sides of the frame. A connecting rod is provided on the inner wall of opposite sides of the frame. An assembly frame is provided at one end of the connecting rod. A storage rack, a support column, and two transmission rollers are provided on the inner wall of one side of the assembly frame. A support plate is installed on the inner wall of opposite sides of the assembly frame via bearings. A rotating shaft and three rollers are provided on the outer wall of one side of the support plate. A limit rod is provided on the top outer wall of the support plate. An electric telescopic rod is provided on the outer wall of the support column. A connecting frame is provided at the movable end of the electric telescopic rod. A cutting assembly is provided at one end of the connecting frame. Gears are provided on one end of the connecting frame and on the outer wall of the rotating shaft.

[0011] In this case, adhesive tape is used as the fixing material, which makes subsequent film packaging more convenient. The fixing mechanism can quickly cut the tape and fix the end of the rolled film to prevent the film from unraveling after winding. The electric telescopic rod drives the gear to rotate, which enables mechanical transmission between components. The connecting frame and the rotating shaft can move synchronously, so that the cutting component can accurately position the tape to the cutting position. This achieves automated design, simplifies the film fixing operation process, and improves the ease of use of the equipment.

[0012] In a preferred embodiment, a sliding groove is provided on the inner wall of each opposite side of the frame, a fixed frame is slidably installed on the inner wall of the sliding groove, a non-stick plate is provided on one outer wall of the fixed frame, an installation groove is provided on one outer wall of the fixed frame, a pressure roller is slidably installed on the inner wall of the installation groove, and a scraper is provided on one outer wall of the fixed frame, the scraper and the roller are used in cooperation.

[0013] After the film is cut by the cutting mechanism, the pressure roller fixes the end of the film to the non-stick plate. The roller then applies tape to the end of the film. The cutting component cuts the tape to a suitable length. The fixing frame then moves slowly along the chute to wind up the film on the take-up roller. At the very end, the pressure roller releases the film, and the force of the rotating take-up roller, along with the scraper, makes the tape and film adhere more tightly, thus fixing the end of the film and preventing it from falling off and affecting subsequent processes.

[0014] In a preferred embodiment, the cutting mechanism includes a slide rod and a threaded rod, both of which are disposed on the inner wall of opposite sides of the frame. The same fixing sleeve is disposed on the outer wall of both the slide rod and the threaded rod. An electric lifting rod is disposed on the bottom outer wall of the fixing sleeve. A dividing component is disposed at the movable end of the electric lifting rod. A limit component is disposed directly below the dividing component.

[0015] The electric lifting rod, sliding rod, and threaded rod ensure that the fixing sleeve and its dividing components can be accurately positioned along the preset path, thereby achieving precise cutting of the film, reducing errors and waste. The addition of limiting components can effectively prevent the film from shifting, curling, or tearing due to tension imbalance during the cutting process, further ensuring the accuracy of cutting and the integrity of the film.

[0016] As described above, a winding device for fully biodegradable films includes a frame, guide rollers, winding rollers, and a conveying assembly. It also includes: a cutting mechanism disposed on the inner wall of an opposite side of the frame; and a fixing mechanism disposed on the inner wall of an opposite side of the frame. Connecting rods are provided on the inner walls of the opposite sides of the frame, with an assembly frame at one end of each connecting rod. A storage rack, a support column, and two transmission rollers are provided on one inner wall of the assembly frame. Support plates are mounted on the inner walls of the opposite sides of the assembly frame via bearings. A rotating shaft and three rollers are provided on the outer wall of one side of the support plate. A limit rod is provided on the top outer wall of the support plate. An electric telescopic rod is provided on the outer wall of the support column. A connecting frame is provided at the movable end of the electric telescopic rod. A cutting assembly is provided at one end of the connecting frame. Gears are provided on one end of the connecting frame and on the outer wall of the rotating shaft. The winding device for fully biodegradable films provided by this invention improves ease of use, prevents film end scattering, and simplifies the operation process. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] The present invention discloses a winding device for fully biodegradable films, which is mainly used in scenarios where the film tail end on the winding roller is not fixed when the film is being cut. The originally balanced tension may become unbalanced due to the loss of constraint at one end, causing the film to unravel and affecting subsequent work.

[0026] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 A winding device for fully biodegradable films includes a frame 1, guide rollers 2, winding rollers 15, and conveying assembly 3. It also includes: a cutting mechanism: the cutting mechanism is disposed on the inner wall of opposite sides of the frame 1; a fixing mechanism: the fixing mechanism is disposed on the inner wall of opposite sides of the frame 1. Connecting rods are provided on the inner walls of opposite sides of the frame 1, and an assembly frame 9 is provided at one end of each connecting rod. A storage rack 24, a support column 23, and two transmission rollers 20 are provided on one inner wall of one side of the assembly frame 9. Support plates 21 are mounted on the inner walls of opposite sides of the assembly frame 9 via bearings. A rotating shaft and three rollers 22 are provided on the outer wall of one side of the support plate 21. A limit rod is provided on the top outer wall of the support plate 21. An electric telescopic rod 25 is provided on the outer wall of the support column 23. A connecting frame is provided at the movable end of the electric telescopic rod 25. A cutting assembly 26 is provided at one end of the connecting frame. Gears are provided on one end of the connecting frame and the outer wall of the rotating shaft.

[0027] A storage hole is provided on the top outer wall of the storage rack 24, and a limiting rod is set on the inner circumference of the storage hole.

[0028] Mounting rods 10 are provided on the inner walls of opposite sides of the frame 1. One end of the mounting rod 10 is provided with a mounting post 12. One end of the mounting post 12 is provided with a threaded groove. The inner wall of the threaded groove is provided with a mounting cover 11.

[0029] The mounting post 12 and the mounting cover 11 are connected by threads, which enables the tape to be installed detachably. When the tape needs to be replaced, the old tape can be easily removed and the new tape can be replaced simply by rotating the mounting cover 11, which greatly simplifies the replacement process.

[0030] In this case, adhesive tape is used as the fixing material, which makes subsequent film packaging more convenient. The fixing mechanism can quickly cut the tape and fix the end of the rolled film to prevent the end of the film from unraveling after winding. The electric telescopic rod 25 drives the gear to rotate, which enables mechanical transmission between components. The connecting frame and the rotating shaft can move synchronously, so that the cutting component 26 can accurately position the cutting position of the tape. This realizes the automated design, simplifies the film fixing operation process, and improves the ease of use of the equipment.

[0031] For example, in actual operation, when the fully biodegradable film is wound to the predetermined length or a new roll needs to be replaced, the fixing mechanism plays a key role. The operator only needs to start the electric telescopic rod 25 through the control panel. The electric telescopic rod 25 will quickly and accurately drive the connecting frame and support plate 21 to rotate, ensuring that the cutting assembly 26 can accurately position the tape to the cutting position.

[0032] Reference Figure 1 and Figure 4 In a preferred embodiment, a sliding groove 14 is provided on the inner wall of opposite sides of the frame 1. A fixed frame 17 is slidably installed on the inner wall of the sliding groove 14. A non-stick plate 19 is provided on one outer wall of the fixed frame 17. An installation groove is provided on one outer wall of the fixed frame 17. A pressure roller 18 is slidably installed on the inner wall of the installation groove. A scraper 13 is provided on one outer wall of the fixed frame 17. The scraper 13 and the roller 22 are used in cooperation.

[0033] After the film is cut by the cutting mechanism, the end of the film is fixed on the non-stick plate 19 by the pressure roller 18. The tape is then attached to the end of the film by the roller 22. When the tape of appropriate length is cut by the cutting component 26, the fixing frame 17 moves slowly along the slide 14 to wind up the film on the take-up roller 15. At the very end, the pressure roller 18 releases the film, and the force of the rotating take-up roller 15, together with the scraper 13, makes the tape and film adhere more tightly, thus fixing the end of the film and preventing the film from falling off and affecting subsequent processes.

[0034] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the cutting mechanism includes a slide bar 8 and a threaded bar 6. The slide bar 8 and the threaded bar 6 are both disposed on the inner wall of opposite sides of the frame 1. The same fixing sleeve 7 is disposed on the outer wall of the slide bar 8 and the threaded bar 6. An electric lifting rod 16 is disposed on the bottom outer wall of the fixing sleeve 7. A dividing component is disposed at the movable end of the electric lifting rod 16. A limit component is disposed directly below the dividing component.

[0035] The electric lifting rod 16, sliding rod 8 and threaded rod 6 ensure that the fixed sleeve 7 and its dividing components can be accurately positioned along the preset path, thereby achieving precise cutting of the film, reducing errors and waste. The addition of limiting components can effectively prevent the film from shifting, curling or tearing due to tension imbalance during the cutting process, further ensuring the accuracy of cutting and the integrity of the film.

[0036] Reference Figure 3 and Figure 4 In a preferred embodiment, the limiting component includes a mounting frame 4, which is disposed on the inner wall of the opposite side of the frame 1. A slit is provided on the bottom inner wall of the mounting frame 4, and two fixing grooves are provided on the inner wall of the opposite side of the mounting frame 4. A pressure plate 5 is slidably installed inside the fixing groove.

[0037] Mounting bracket 4 is fixed on the inner wall of the opposite side of the frame 1. The slits opened on the bottom inner wall of the mounting bracket correspond precisely to the position of the dividing components, ensuring that the film can be accurately limited during the cutting process and avoiding deviation or jumping. The pressure plate 5 is slidably mounted on the mounting bracket 4 through the fixing groove, and can be flexibly adjusted according to the thickness of the film to provide stable support for the film and prevent damage due to uneven force during cutting.

[0038] Reference Figure 1 and Figure 2 In a preferred embodiment, the guide roller 2, the conveying assembly 3, and the take-up roller 15 are all disposed on the inner wall of opposite sides of the frame 1, and the outer circumferential wall of the guide roller 2 is provided with bidirectional spiral ribs.

[0039] The presence of bidirectional spiral ridges provides a continuous and regular guiding path for the film. When the film passes through guide roller 2, these ridges can effectively prevent the film from sticking or folding, ensuring that the film unfolds in a flat and uniform state.

[0040] Working principle: In use, after the film and tape are installed, the film is wound up. When the film is wound to the predetermined length, the cutting mechanism uses the pressure plate 5 to fix it, and the dividing component divides it. After the division, the pressure plate 5 slowly releases the film. When the end of the film moves to the middle position of the non-stick plate 19, the pressure roller 18 fixes it. The tape is then attached to the end of the film with the roller 22. The tape of appropriate length is then cut by the cutting component 26. Subsequently, the fixing frame 17 moves slowly along the slide 14 to wind up the film with the winding roller 15. At the very end, the pressure roller 18 releases the film. The force of the rotating winding roller 15, together with the scraper 13, makes the tape and film adhere more tightly, thus fixing the end of the film with the tape.

[0041] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
