Description

Technical Field

[0001] This utility model relates to the field of film processing equipment technology, specifically a film folding device with a correction function. Background Technology

[0002] In the field of film processing, film folding is a crucial process, widely used in numerous industries such as plastic packaging, food packaging, and electronic materials. As industries increasingly demand higher quality and precision in film products, the accuracy and stability of the film folding process become ever more critical.

[0003] Chinese Patent Publication No. CN217533553U discloses a double-layer film folding mechanism, relating to the field of film folding machines. This double-layer film folding mechanism includes a base, a limiting component, and an adjusting component for adjusting the film position. The upper surface of the base is provided with two support seats and two connecting rods. A film mounting rod and a first guide rod are disposed between the two support seats, and a second guide rod is disposed between the two connecting rods. A folding rod is disposed on the upper surface of the base. Under the action of the adjusting component, the center position of the film is positioned between the first and second bonding rods. The film, which is then bonded to the first and second bonding rods, is folded and connected to the folding rod. The folding rod then moves the film outward, connecting it to a winding mechanism for winding up the folded film.

[0004] In existing technologies, the use of a double-layer film folding mechanism lacks a limiting design for the lateral movement of the film. The absence of key components such as guide rollers and adjustable limiting rings can easily cause the film to deviate during transport, severely affecting folding accuracy and winding quality. Furthermore, it cannot be flexibly adjusted to accommodate films of different widths, which limits its applicability when dealing with various film specifications, significantly reducing its versatility and practicality in different production scenarios. Therefore, we propose an improvement: a film folding device with a deviation correction function. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Example 1: Please refer to the appendix of the instruction manual. Figure 1-5 A film folding device with a correction function includes a base 1, on which two first fixing seats 2 are fixedly installed. A second fixing seat 3 is fixedly installed on the side of one of the first fixing seats 2 away from the base 1. A first side plate 4 is provided on one side of each of the two first fixing seats 2. A guide roller 6 is provided between each adjacent first fixing seat 2 and the first side plate 4. Two limiting rings 7 are slidably connected to the outer sides of each of the two guide rollers 6.

The fixing plates 8 and connecting blocks 15 are respectively inserted into the interior of the first fixing seat 2 and the first side plate 4 and slidably connected thereto.

[0034] In this embodiment of the invention, when the film shifts, the first servo motor 11 can quickly respond and drive the first worm gear 12 to rotate. Through meshing transmission with the first worm wheel 13, the rotational motion is converted into linear motion of the sleeve 10 and the first threaded rod 9, thereby causing the limiting ring 7 to slide and promptly correcting the film shift. Compared with traditional manual or simple mechanical correction methods, this automated adjustment structure has the advantages of fast response speed and high adjustment accuracy, which can greatly improve the quality and production efficiency of film folding, reduce scrap rate, and lower production costs.

[0035] In this embodiment of the invention, the combined design of the guide roller 6 and the limiting ring 7 enables precise guidance and positioning of the film during transport. The guide roller 6 provides a stable transport path for the film, while the limiting ring 7 can be flexibly adjusted according to the width of the film to restrict the lateral movement of the film during transport and prevent the film from deviating.

[0036] Example 2: Please refer to the appendix of the instruction manual. Figure 2-5 In a preferred embodiment of this utility model, the adjustment structure includes two first threaded rods 9 and sleeves 10. The two first threaded rods 9 are respectively inserted into the interior of the two sleeves 10 and threadedly connected thereto. Both first threaded rods 9 are fixedly connected to the limiting rings 7. Both sleeves 10 pass through one side of the fixing plate 8 and are rotatably connected thereto. A first servo motor 11 is fixedly installed inside the fixing plate 8. A first worm gear 12 is fixedly installed at the output end of the first servo motor 11. Two first worm wheels 13 mesh with the outer side of the first worm gear 12. The two first worm wheels 13 are respectively fixedly installed on the outer side of the two sleeves 10. The first worm gear 12 and the two first worm wheels 13 are rotatably connected to the fixing plate 8.

[0037] Each of the multiple first threaded rods 9 is fixedly installed with a first limiting plate 14 on the side away from the limiting ring 7, and the first limiting plate 14 is inserted into the inside of the sleeve 10 and slidably connected thereto. The multiple sleeves 10 are respectively inserted into the inner wall of the first fixed seat 2 and the first side plate 4 and slidably connected thereto.

[0038] Each of the multiple connecting blocks 15 has an insert block 17 inside, and the insert block 17 passes through one side of the connecting block 15 and is slidably connected to it. Each of the multiple insert blocks 17 has a second threaded rod 16 on the side away from the connecting block 15. The second threaded rod 16 is inserted into the interior of the insert block 17 and is threadedly connected to it. Each of the two first side plates 4 has a second worm 18 and a second worm wheel 19 rotatably connected inside, and the second worm 18 and the second worm wheel 19 mesh. The second worm wheel 19 is fixedly connected to the second threaded rod 16. A handle is fixedly installed on the top of the second worm 18, and the handle passes through the top of the first side plate 4 and is rotatably connected to it.

[0039] A second side plate 5 is provided on one side of the second fixed seat 3. The second side plate 5 is fixedly connected to the first side plate 4 on one side of one of the first fixed seats 2. A film placement roller 22 is rotatably connected between the second fixed seat 3 and the second side plate 5. A second servo motor 21 is fixedly installed inside the second fixed seat 3. The output end of the second servo motor 21 is fixedly connected to the film placement roller 22.

[0040] An auxiliary block 20 is fixedly installed on one side of the second side plate 5 and the two first side plates 4. The auxiliary block 20 is slidably connected to the second fixed seat 3 and the two first fixed seats 2.

[0041] A fixing block 23 is fixedly installed on one side of each of the two first side plates 4. Both fixing blocks 23 are inserted into the interior of the base 1 and slidably connected thereto. Multiple fixing bolts are provided on the side of each fixing block 23 away from the base 1. The multiple fixing bolts are inserted into the interior of the base 1 and threadedly connected thereto. The multiple fixing bolts pass through the fixing block 23 and are threadedly connected thereto.

[0042] A controller 24 is embedded on one side of the base 1. The controller 24 is electrically connected to the first servo motor 11 and the second servo motor 21. A thin film folding mechanism is provided on the base 1.

[0043] In this embodiment of the invention, the operator rotates the handwheel to drive the second worm gear 18 to rotate within the first side plate 4. The second worm gear 18 meshes with the second worm wheel 19, transmitting the rotational motion to the second worm wheel 19, which in turn causes the second threaded rod 16, which is fixedly connected to the second worm wheel 19, to rotate. Since the second threaded rod 16 and the insert block 17 are threadedly connected, the rotation of the second threaded rod 16 is converted into linear sliding of the insert block 17 within the connecting block 15, thereby achieving fine adjustment of the position of the connecting block 15. This fine adjustment action can precisely calibrate the position of the guide roller 6 and related components, ensuring the accuracy of the film conveying path. By manually fine-tuning the position of the connecting block 15, the restriction on the position of the guide roller 6 is removed, further facilitating the adjustment of the angle of the guide roller 6, enabling the equipment to better adapt to diverse production needs.

[0044] The second servo motor 21 is powered on and its output shaft drives the film placement roller 22 to rotate in a circular motion. The film wound on the film placement roller 22 is gradually unfolded under the friction force generated by the rotation of the roller and conveyed forward along the preset conveying path under the guidance of the guide roller 6. The precise drive of the second servo motor 21 can ensure that the film is conveyed at a constant speed and tension, avoiding problems such as wrinkles and stretching deformation of the film caused by speed fluctuations or uneven tension.

[0045] The sliding connection between the fixing block 23 and the base 1 allows the two first side plates 4 to be flexibly adjusted in position according to actual needs during installation, enabling rapid equipment assembly without a complicated calibration process. The cooperation between the auxiliary block 20 and the fixing base enhances the stability of the overall equipment structure and reduces the interference of side plate swaying on the film conveying path, thereby improving the reliability of film conveying and providing a prerequisite for high-quality film folding.

[0046] During the film folding process, the controller 24 can quickly respond to abnormal situations such as film offset and adjust the first servo motor 11 in a timely manner to achieve correction adjustment. At the same time, it stably controls the second servo motor 21 to ensure stable film delivery, realizing an automated and intelligent production process, reducing manual intervention, and improving production efficiency and product quality consistency. The film folding mechanism set on the base 1 works closely with other components to form a complete film folding production line under the unified control of the controller 24.

[0047] Example 3: Please refer to the appendix of the instruction manual. Figure 2-4 In a preferred embodiment of this utility model, each of the multiple limiting rings 7 has a support rod at its top, which is inserted into the limiting ring 7 and slidably connected to it. The bottom of each of the multiple support rods is rotatably connected to a pressure roller via a rotating shaft. Each of the multiple limiting rings 7 has a third threaded rod at its top, which passes through the support rod and is threadedly connected to it. The third threaded rod is inserted into the limiting ring 7 and rotatably connected to it. Each of the multiple support rods has a limiting plate fixedly installed at its bottom, which is slidably connected to the limiting ring 7. Each of the multiple third threaded rods has a connecting plate fixedly installed at its bottom, which is rotatably connected to the limiting ring 7.

[0048] In this embodiment of the invention, the operator rotates the third threaded rod. Since the third threaded rod and the support rod are connected by a thread, as the third threaded rod rotates, the support rod will move up and down along the axial direction of the third threaded rod. The pressure roller connected to the bottom of the support rod through a rotating shaft will also adjust its height accordingly.

[0049] When the support rod moves downward, the pressure roller gradually approaches the film surface and exerts a certain pressure on the film; conversely, when the support rod moves upward, the pressure between the pressure roller and the film decreases; the limiting plate fixedly installed at the bottom of the support rod slides in conjunction with the limiting ring 7, which can prevent the support rod from tilting or deviating during the movement, and ensure the stability and accuracy of the pressure roller adjustment.

[0050] In this embodiment of the invention, the pressure roller and its adjustment structure can flexibly adjust the pressing force on the film according to the actual condition of the film. For thinner, more easily deformable films, the pressure of the pressure roller can be appropriately reduced to avoid film damage or indentation due to excessive pressure. For thicker, more rigid films, the pressure of the pressure roller can be increased to ensure that the film remains flat during transport and does not wrinkle or curl. This precise pressure adjustment not only effectively improves the transport quality of the film but also provides favorable conditions for the subsequent folding process, ensuring that the folded film surface is flat and the dimensions are accurate, thus improving the overall quality of the film product.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
