Description

Technical Field

[0001] This utility model relates to the field of plastic sealant production and processing technology, specifically a winding device for producing wear-resistant plastic sealant. Background Technology

[0002] Laminating film is a plastic film used to protect and enhance the surface of paper documents, photos, cards, and other items. The core principle of lamination is to sandwich the item to be laminated between two layers of laminating film (or a folded sheet of laminating film) with hot melt adhesive, and then feed it into a laminating machine. The laminating machine uses heated rollers or a flat plate to melt the hot melt adhesive and applies pressure, causing the molten adhesive to distribute evenly and adhere tightly to the surface of the item. The item and film then pass through a cooling zone (or cool naturally), where the hot melt adhesive solidifies, permanently bonding the two layers of film to the top and bottom surfaces of the item, forming a sealed, sturdy, and transparent protective sleeve. In summary, laminating film is like putting a sturdy, transparent, and waterproof "plastic armor" on paper or other items. Through heating and pressurization, it uses its own hot melt adhesive layer to seal and wrap the item, providing comprehensive protection and aesthetic enhancement. It is a widely used consumable in offices, education, homes, and commercial displays. Abrasion-resistant laminating film is a protective film that provides superior scratch and abrasion resistance through special materials (such as PET), surface coatings, and / or thickening treatments. It is ideal for important documents, cards, photos, and other items that require long-term preservation, frequent use, or are exposed to abrasive environments, effectively protecting their surface integrity and clarity and extending their lifespan.

[0003] For example, Chinese patent CN222922588U discloses a film winding device, including a base and a vertical support frame. The vertical support frame is fixedly connected to one side of the base. A winding structure is provided at the top of the vertical support frame, and a push-off structure is provided at the bottom of the vertical support frame for pushing the film roll off the winding structure. A support structure is fixedly connected to the top of the base, and the top of the support structure is in contact with one end of the winding structure. The winding structure includes a cylinder embedded in the top of the vertical support frame, and a winding roller is rotatably connected inside the cylinder via a bearing. A winding motor is fixedly connected to one side of the vertical support frame. This invention uses the winding structure to drive the paper tube to rotate, thereby winding the film. After winding, the push-off structure directly pushes the film roll off the winding structure, facilitating the collection of the film roll. The support structure provides support to the end of the winding structure during winding.

[0004] However, during the conveying process, the laminating film is prone to deviation or wrinkles, which leads to poor flatness of the laminating film during the winding process, high labor intensity for workers, and low work efficiency. At the same time, the laminating film cannot be clamped during cutting, which easily causes the laminating film to shrink during the cutting process. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a winding device for producing wear-resistant plastic sealant film, which flattens and guides the plastic sealant film, improves the winding effect, and avoids shrinkage of the plastic sealant film during the cutting process.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a winding device for producing wear-resistant plastic sealing film, including a conveyor belt, a guide assembly, a winding roller, a leveling mechanism, and a cutting mechanism.

[0009] Furthermore, the leveling seat is also provided with a sliding cavity that communicates with the sliding groove. A slidable limiting plate is provided in the sliding cavity, and the sliding column extends into the sliding cavity and is fixedly connected to the limiting plate.

[0010] Furthermore, the output end of the conveyor belt is provided with a rotatable flattening roller.

[0011] Furthermore, the guiding assembly includes a guide roller and a pressure plate. The guide roller is arranged parallel to the take-up roller, and the pressure plate is located on both sides of the guide roller, and the pressure plate can move up and down relative to the guide roller.

[0033] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0034] like Figure 1-6 As shown, in this embodiment, a winding device for producing wear-resistant plastic sealing film is provided, including a conveyor belt 1, a guide assembly 2, a winding roller 3, a leveling mechanism 4, and a cutting mechanism 5. The leveling mechanism 4 is located above the conveyor belt 1, the guide assembly 2 and the winding roller 3 are both located behind the conveyor belt 1, and the cutting mechanism 5 is located between the guide assembly 2 and the winding roller 3.

[0035] like Figure 1-2As shown in Figures 4-5, in this embodiment, the leveling mechanism 4 includes a leveling plate 41 and a leveling seat 42 located above the conveyor belt 1 and movable up and down relative to the conveyor belt 1. The leveling plate 41 is slidably mounted on the leveling seat 42. Specifically, the leveling seat 42 is located above the leveling plate 41. A sliding post 411 is fixedly provided on the leveling plate 41, and a groove 421 corresponding to the sliding post 411 is provided on the leveling seat 42. The sliding post 411 is slidably disposed in the groove 421, so that the leveling plate 41... The leveling seat 42 is slidable. In order to prevent the sliding column 411 from sliding out of the slide groove 421, the leveling seat 42 is also provided with a sliding cavity 422 that communicates with the slide groove 421. A sliding limiting plate 423 is provided in the sliding cavity 422. The sliding column 411 extends into the sliding cavity 422 and is fixedly connected to the limiting plate 423. When the bottom of the sliding column 411 slides to the slide groove 421, the limiting plate 423 abuts against the side wall of the sliding cavity 422 to prevent the sliding column 411 from detaching from the slide groove 421.

[0036] like Figure 4-5 As shown, in this embodiment, a compression spring 43 is sleeved on the sliding column 411. The two ends of the compression spring 43 are fixedly connected to the sides of the leveling plate 41 and the leveling seat 42 that are close to each other. When the compression spring 43 is in its original state, the limiting plate 423 abuts against the side wall of the sliding cavity 422. During operation, the leveling plate 41 and the leveling seat 42 move downward relative to the conveyor belt 1 until the leveling plate 41 abuts against the plastic sealing film on the conveyor belt 1, thereby leveling the plastic sealing film. When there are wrinkles or protrusions on the surface of the plastic sealing film, the leveling plate 41 will be lifted up, causing the leveling plate 41 to move upward relative to the leveling seat 42, so that the compression spring 43 is compressed to a certain length. At this time, the spring applies a downward pressure to the leveling plate 41. The elastic force of the compression spring 43 can make the leveling plate 41 always abut against the plastic sealing film, thereby leveling the wrinkles on the surface of the plastic sealing film.

[0037] like Figure 1-2 As shown in Figures 4-5, in this embodiment, in order to improve the stability of the sliding of the flat plate 41 relative to the flat seat 42, and to prevent the flat plate 41 from rotating relative to the flat seat 42, two sliding columns 411 are provided. In other embodiments not shown, the number of sliding columns 411 may also be one or more.

[0038] like Figure 1-2 As shown in Figures 4-5, in this embodiment, a leveling frame 44 is fixedly provided on the conveyor belt 1, and an electric push rod 45 is fixedly provided on the leveling frame 44. The output end of the electric push rod 45 is fixedly connected to the leveling seat 42, so that the electric push rod 45 can drive the leveling seat 42 and the leveling plate 41 to move up and down relative to the conveyor belt 1.

[0039] like Figure 1-2As shown, in this embodiment, the output end of the conveyor belt 1 is provided with a rotatable flattening roller 11. The plastic sealing film passes through the flattening roller 11 and the conveyor belt 1 to reach the guide assembly 2. The flattening roller 11 plays a guiding role.

[0040] like Figure 1-3 As shown, in this embodiment, the guide assembly 2 includes a guide roller 21 and a pressure plate 22. The guide roller 21 is arranged parallel to the take-up roller 3. The pressure plate 22 is located on both sides of the guide roller 21 and can move up and down relative to the guide roller 21. Specifically, the guide roller 21 is rotatably mounted on the workbench via a mounting base 23. The workbench can be the ground or other flat surfaces. There are two mounting bases 23, and a guide rod is fixed between the two mounting bases 23. The guide roller 21 is rotatably sleeved on the guide rod. One side of the pressure plate 22 is attached to the surface of the guide roller 21, and the other side of the pressure plate 22 is slidably mounted on the mounting base 23.

[0041] like Figure 3 As shown, in this embodiment, a connecting rod 24 is fixedly provided on the pressure plate 22, and a mounting groove corresponding to the connecting rod 24 is provided on the mounting base 23. The connecting rod 24 is slidably disposed in the mounting groove, so that the connecting rod 24 can slide relative to the mounting base 23 and the guide roller 21. A compression spring 25 is also fixedly provided between the connecting rod 24 and the mounting base 23. The compression spring 25 is sleeved on the connecting rod 24. During operation, the plastic sealing film passes through the upper surface of the guide roller 21, pulling the pressure plate 22, so that the plastic sealing film is located between the guide roller 21 and the pressure plate 22. By setting the compression spring 25, the elastic deformation of the compression spring 25 is used to ensure that the pressure plate 22 can always be pressed against the surface of the plastic sealing film during operation, further leveling and guiding the plastic sealing film, and avoiding deviation that affects the winding effect.

[0042] like Figure 1 , 2As shown in Figure 6, in this embodiment, the cutting mechanism 5 includes a positioning plate 51 and a cutter 52. The cutter 52 is slidable relative to the positioning plate 51. Specifically, the cutter 52 is fixedly mounted on a blade holder 53, which is slidably positioned above the positioning plate 51. A sliding rod 531 is fixedly mounted on the blade holder 53, and a sliding sleeve 512 corresponding to the sliding rod 531 is fixedly mounted on the positioning plate 51. The sliding rod 531 is slidably positioned inside the sliding sleeve 512. A through slot 511 for the cutter 52 to pass through is provided on the positioning plate 51. The cutting mechanism 5 also includes a cutting platform 54 fixedly mounted on the worktable. The cutting platform 54 is located between the guide assembly 2 and the take-up roller 3. The frame 53 and the positioning plate 51 can move up and down relative to the cutting platform 54. The upper side of the cutting platform 54 is flush with the upper side of the guide roller 21. The cutting platform 54 has a groove 541 corresponding to the cutter 52. During operation, the plastic sealant passes through the guide assembly 2 and the cutting platform 54 in sequence, and is then wound up by the winding roller 3. When it is wound to a certain length, the cutter holder 53 and the positioning plate 51 of the cutting platform 54 move downward relative to the cutting platform 54 until the positioning plate 51 abuts against the surface of the plastic sealant. The cutter holder 53 continues to move downward, and the cutter 52 passes through the through groove 511 on the positioning plate 51 to cut the plastic sealant. The groove 541 on the cutting platform 54 can prevent the cutter 52 from being damaged during cutting.

[0043] like Figure 1 , 2 As shown in Figure 6, in this embodiment, a cutting frame 55 is fixedly provided on the cutting platform 54, and a driving cylinder 56 is fixedly provided on the cutting frame 55. The output end of the driving cylinder 56 is fixedly connected to the tool holder 53, so that the driving cylinder 56 can drive the tool holder 53 and the positioning plate 51 to move up and down relative to the cutting platform 54.

[0044] The working process and principle of this utility model are as follows: The plastic sealing film is placed on the conveyor belt 1. The electric push rod 45 drives the leveling plate 41 and the leveling seat 42 to move downwards relative to the conveyor belt 1 until the leveling plate 41 abuts against the plastic sealing film on the conveyor belt 1, thus leveling the plastic sealing film. When there are wrinkles or protrusions on the surface of the plastic sealing film, the leveling plate 41 is lifted, causing it to move upwards relative to the leveling seat 42. This compresses the compression spring 43 by a certain length. At this time, the spring applies a downward pressure to the leveling plate 41. The elastic force of the compression spring 43 ensures that the leveling plate 41 remains abutting against the plastic sealing film, thereby leveling the wrinkles on the surface of the plastic sealing film. After leveling, the plastic sealing film reaches the guide roller 21 via the flattening roller 11 at the output end of the conveyor belt 1, pulling the pressure plate 22 so that the plastic sealing film is positioned on the guide roller 21. Between the pressure plate 22 and the pressure plate 22, a clamping spring 25 is set. The elastic deformation of the clamping spring 25 ensures that the pressure plate 22 remains in close contact with the surface of the plastic sealant during operation, further leveling and guiding the plastic sealant to prevent deviation and affecting the winding effect. Subsequently, the plastic sealant passes through the cutting platform 54 to the winding roller 3 and is wound by the winding roller 3. When it is wound to a certain length, the drive cylinder 56 drives the cutter holder 53 and the positioning plate 51 of the cutting platform 54 to move downward relative to the cutting platform 54 until the positioning plate 51 abuts against the surface of the plastic sealant. The drive cylinder 56 drives the cutter holder 53 to continue to move downward. The cutter holder 53 and the cutter 52 slide relative to the positioning plate 51. The cutter 52 passes through the through groove 511 on the positioning plate 51 to cut the plastic sealant. The groove 541 on the cutting platform 54 can prevent the cutter 52 from being damaged during cutting.

[0045] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
