Description

Technical Field

[0001] The utility model relates to the technical field of laminated paper, and more specifically to a pull-resistant double-sided laminated paper. Background Art

[0002] Laminated paper is a composite material made by coating plastic particles on the surface of paper through a cast film machine. Its main features are that this composite material is relatively oil-proof, relatively waterproof, and can be heat-sealed. Different uses take different characteristics: when used to package hamburgers, it takes advantage of its oil-proof properties. For example, McDonald's uses 80-degree edible vegetable oil without oil leakage for 10 minutes. When used for packaging coated paper, it takes advantage of its waterproof properties. When used for packaging in automatic packaging machines, it takes advantage of its heat-sealing properties.

[0003] The patent document with publication number CN218373023U in the prior art provides a tensile-resistant double-sided laminated paper. The device increases its tensile resistance by installing components and adding cross carbon fiber strips inside the double-layer laminated paper. The burrs and fiber grid layers increase the grip between the double-layer laminated layers, solving the problem of strong tensile resistance at every point inside the laminated paper when cutting the laminated paper. It has a simple structure and low cost, which expands the scope of application and practicality of the tensile-resistant laminated paper.

[0004] Although this device has many beneficial effects, the following problems still exist: during the use of this device, the tensile strength increased by relying solely on carbon fiber strips is limited, the tensile strength is insufficient, and the coated paper is easy to break; secondly, during the use of this device, the coated paper is not easy to tear and cut at the required position, which is inconvenient to use and needs to be improved. In view of this, we propose a tensile-resistant double-sided coated paper. Utility Model Content

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0027] See also Figure 1-5 ,The utility model provides a technical solution:

[0028] A tear-resistant double-sided laminated paper comprises a base paper layer 1, a pressure-resistant layer 2 is fixedly arranged on the top of the base paper layer 1, a laminated paper layer 3 is fixedly arranged on the bottom of the base paper layer 1 and the top of the pressure-resistant layer 2, the laminated paper layer 3 comprises a lower laminated layer 301, support bars 302 are fixedly arranged on both sides of the top of the lower laminated layer 301, a plurality of reinforcement rings 303 are fixedly arranged on the top of the lower laminated layer 301, tensile strips 304 are fixedly arranged on the circumferential side walls of the reinforcement rings 303, connecting strips 305 are fixedly arranged on the circumferential outer walls of longitudinally adjacent reinforcement rings 303, splicing strips 306 are fixedly arranged on the circumferential outer walls of transversely adjacent reinforcement rings 303, an upper laminated layer 307 is fixedly arranged on the top of the support bar 302, a reel 4 is sleeved on the bottom of the laminated paper layer 3, and a cutting component 5 is fixedly arranged on the side wall of the reel 4. The utility model prevents the tensile-resistant double-sided laminated paper from being squeezed and damaged by the pressure-resistant layer 2, forms an inner lining structure on the top of the lower laminated layer 301 through the reinforcement ring 303, reinforces the laminated paper layer 3, and improves the tensile resistance of the tensile-resistant double-sided laminated paper, supports the upper laminated layer 307 through the support bar 302, fixes the reinforcement ring 303 through the connecting bar 305 and the splicing bar 306, and facilitates the winding of the tensile-resistant double-sided laminated paper through the reel 4.

[0029] Specifically, the cutting assembly 5 includes a fixed rod 501, a fixed plate 502 is provided at the top of the side wall of the fixed rod 501, a knife groove 503 is provided at the bottom of the fixed plate 502, a cutting knife 504 is slidably connected to the knife groove 503, a connecting rod 505 is fixed to the top of the cutting knife 504, and a spring 506 is sleeved on the outer wall of the connecting rod 505. A bottom plate 507 is fixed to the bottom of the fixed plate 502. With the fixing rod 501 securing the cutting assembly 5, the staff moves the connecting rod 505 upward to facilitate the entry of the cutting knife 504 into the knife groove 503. The staff then places the desired side of the anti-pull double-sided laminated paper on top of the bottom plate 507. The connecting rod 505 is released, and the rebound force of the spring 506 drives the cutting knife 504 downward to cut a cut in the double-sided laminated paper, making it easier to tear it open.

[0030] Furthermore, the pressure-resistant layer 2 has a honeycomb structure, is filled with an inert gas, and the cross-section of the tensile strip 304 is X-shaped. The pressure-resistant layer 2 filled with an inert gas improves the compressive resistance of the tensile-resistant double-sided laminated paper, while the tensile strip 304 with an X-shaped cross-section effectively improves the tensile resistance of the tensile-resistant double-sided laminated paper.

[0031] It is worth noting that the lower coating layer 301 is provided with reinforcing ribs 308, which are a mesh structure. The mesh structure of the reinforcing ribs 308 improves the toughness of the lower coating layer 301, so that the tensile double-sided coated paper will not break easily.

[0032] It should be noted that a pull plate 508 is fixedly provided on the top of the connecting rod 505 through the fixed plate 502, and the diameter of the pull plate 508 is larger than the diameter of the connecting rod 505. The pull plate 508 on the top of the connecting rod 505 is convenient for the staff to use and prevents the connecting rod 505 from detaching.

[0033] In addition, a cutting groove 509 is provided on the top of the bottom plate 507, and the position of the cutting groove 509 matches the position of the cutting knife 504. The cutting groove 509 matched with the cutting knife 504 prevents the blade of the cutting knife 504 from being damaged, which would affect the subsequent cutting of the double-sided laminated paper.

[0034] Working principle: When the device is needed to be used for tear-resistant double-sided laminated paper, the pressure resistance of the tear-resistant double-sided laminated paper is improved by the pressure-resistant layer 2 filled with inert gas. The reinforcing ring 303 forms an inner lining structure on the top of the lower laminated layer 301 to reinforce the laminated paper layer 3 and improve the tear resistance of the tear-resistant double-sided laminated paper. The upper laminated layer 307 is supported by the supporting bar 302, and the reinforcing ring 303 is fixed by the connecting bar 305 and the splicing bar 306. The cutting component 5 is fixed by the fixing rod 501, and the tear-resistant double-sided laminated paper is rolled up by the reel 4. The staff moves the connecting rod 505 upwards to facilitate the cutting knife 504 to enter the knife groove 5 03, place the side of the anti-pull double-sided laminated paper at the required position on the top of the bottom plate 507, loosen the connecting rod 505, and the rebound force of the spring 506 drives the cutting knife 504 to press down and cut a knife edge on the double-sided laminated paper, which is convenient for tearing and use. The toughness of the lower laminated layer 301 is improved by the reinforcement ribs 308 of the mesh structure, so that the anti-pull double-sided laminated paper will not be easily broken. The pull plate 508 on the top of the connecting rod 505 is convenient for the staff to use and prevent the connecting rod 505 from detaching. The cutting groove 509 whose position matches the cutting knife 504 is used to prevent the blade of the cutting knife 504 from being damaged, which affects the subsequent cutting of the anti-pull double-sided laminated paper.
