[0032] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme of the present application will be further described in combination with specific embodiments.

[0033] Embodiment one:

[0034] In combination with Figures 1 to 2 As shown in the drawings, the embodiment is a production line for sandwich paper card and plastic suction sealing packaging, which comprises a paper card forming mechanism, a plastic suction forming mechanism and a sealing packaging mechanism. The paper card forming mechanism and the plastic suction forming mechanism can be arranged in parallel. The paper card forming mechanism is used to cut any side of the original paper card to obtain an installation opening 12, and fold it into a sandwich paper card 15. The plastic suction forming mechanism is used to heat-press the plastic sheet through the blister mold to form a plastic suction box 14. The sealing packaging mechanism is arranged at the work station where the output end of the paper card forming mechanism and the output end of the plastic suction forming mechanism meet. The sealing packaging mechanism is used to coat the inside of the sandwich paper card 15 obtained by the paper card forming mechanism with plastic suction oil, and then embed the plastic suction box 14 obtained by the plastic suction forming mechanism in the installation opening 12 of the sandwich paper card 15, and finally melt and seal the plastic suction box 14 and the paper card.

[0035] In some embodiments, the paper of the original paper card is made of white card paper made of high-quality raw pulp as the main material, which ensures high purity and few impurities of the paper.

[0036] In some embodiments, the plastic sheet is made of PVC or PET material.

[0037] In some embodiments, the paper card forming mechanism sequentially includes a cutting machine 2, a die cutting machine 3, a creasing machine 4, and a folding machine 5 along the paper card conveying direction. The cutting machine 2 is used to cut the original paper card according to the preset size. The cutting machine 2 is used to cut the large paperboard into small pieces of specified size according to the design requirements. This step is the basis of paper card production, ensuring that the size of each paper card is consistent. The die cutting machine 3 is used to cut the paper card sent out by the cutting machine 2 according to the preset pattern. For paper cards with special shape requirements, such as those with rounded corners, grooves, or other complex patterns, the die cutting machine 3 uses specially customized molds to achieve precise cutting. The creasing machine 4 is used to pre-press the paper card sent out by the die cutting machine 3 to form a crease line. By pre-pressing the crease line on the paper card with the creasing machine 4, the paper card is easier to fold along the predetermined line, reducing the possibility of paper tearing or damage, which is very important to ensure that the finished product has neat edges and accurate angles. The folding machine 5 is used to fold the paper card sent out by the creasing machine 4 to form a sandwiched paper card 15. The folding machine 5 is used to fold the paper card that has been creased to form the desired three-dimensional structure or to prepare for subsequent processing.

[0038] Further, the paper card forming mechanism also includes a laminating machine 1. The laminating machine 1 is located at the input end of the cutting machine 2. If the thickness of the target paper card to be produced is greater than the thickness of the original paper card, multiple original paper cards are stacked and fixed by the laminating machine 1 to achieve the desired thickness. Specifically, in this embodiment, for paper cards that exceed the conventional thickness requirement, multiple ordinary thickness paper cards are stacked and fixed together using the laminating process to form the desired thickness of the paper card. At the same time, attention should be paid to the directionality of the paper during the production process to ensure that the finished product has a smooth and flawless appearance.

[0039] Further, the preset pattern includes cutting an installation opening 12 on one side of the paper card, pre-punching a tear line 13 on the other side of the paper card, and rounding the corners of the paper card. By accurately cutting the installation opening 12, it ensures that the blister box 14 can be securely embedded in the paper card, enhancing the overall stability and aesthetics of the package. Preparing the tear line 13 on the paper card makes it easy for consumers to easily open the package without damaging the internal items or the paper card itself, improving the convenience of consumers. Rounding the corners of the paper card can effectively avoid the harm caused to consumers by sharp corners.

[0040] In some embodiments, the blister forming mechanism includes a blister mold and a blister forming machine 6. The blister forming machine 6 can heat and soften the plastic sheet and press it with the blister mold to obtain the blister box 14. Specifically, in this embodiment, the blister mold is made according to the design size of the product. The blister mold determines the specific shape and size of the blister box 14.

[0041] In some embodiments, the sealing packaging mechanism includes a coating device 7 capable of uniformly coating the inside of the sandwiched paper card 15 with plastic oil, a drying device 8 capable of drying the coated sandwiched paper card 15 to accelerate the drying process of the plastic oil, and a plastic welding device capable of high-frequency fusion sealing treatment of the dried sandwiched paper card 15 and the plastic box 14.

[0042] Further, the plastic oil selected in the embodiment needs to meet the national standard requirements and should meet the corresponding environmental coefficient requirements. In the traditional process, non-environmental type glue or hot melt adhesive is mostly used for sealing, which will pollute the environment and is sensitive to environmental temperature changes, easily cracking or falling off due to temperature changes, and unable to provide sufficient adhesion to ensure the reliability of the sealing.

[0043] Further, as shown in Figure 3 The plastic welding device adopts a high-frequency fusion machine 9, the working platform 10 on the high-frequency fusion machine 9 is capable of rotating, at least two high-frequency molds 11 for placing the plastic box 14 are arranged on the working platform 10, the pressing output end of the high-frequency fusion machine 9 corresponds to the high-frequency mold 11, the plastic box 14 is placed in the inside between the two sides of the sandwiched paper card 15, the protruding part of the plastic box 14 is embedded into the mounting opening 12 of the sandwiched paper card 15, the protruding part of the plastic box 14 is embedded and placed in the high-frequency mold 11, the working platform 10 drives the sandwiched paper card 15 to rotate to the below of the pressing output end of the high-frequency fusion machine 9, and the pressing output end of the high-frequency fusion machine 9 seals the sandwiched paper card 15 and the plastic box 14 on the high-frequency mold 11.

[0044] Specifically, a 5kW high-frequency fusion machine is adopted in the embodiment, and different frequency and power high-frequency fusion machines 9 are selected according to the size of the paper card and the plastic box 14 product, large-size products select high-frequency high-power machines, and small-size products select low-frequency low-power machines, to ensure reliable sealing effect. The high-frequency fusion machine 9 can seal the paper card and the plastic box 14 by using the heat generated by high-frequency current, and is suitable for PVC, PET and other plastic materials, and can provide firm and beautiful sealing effect.

[0045] The various devices involved in the production line in the embodiment are all conventional machines on the market, including the laminating machine 1, the cutting machine 2, the die-cutting machine 3, the creasing machine 4, the folding machine 5, the plastic molding machine 6, and the high-frequency fusion machine 9, etc. Therefore, the specific expansion in the application is not carried out.

[0046] The implementation principle of the production line for sealing and packaging of the sandwiched paper card and the plastic box in the embodiment is as follows:

[0047] For the problems of single paper card structure, improper coating selection and unsatisfactory welding process in traditional process, based on practical experience, the sandwich type paper card 15 is selected, the paper card is coated with suction oil, and the high frequency welding machine 9 is used for high frequency welding, which improves the sealing effect of the paper card and the suction box 14.

[0048] In the structural design of paper cards, the sandwich type paper card 15 improves the overall rigidity and compression resistance through double-sided support design, reduces the risk of separation caused by external force during transportation and handling, and the sandwich structure can better adapt to suction boxes 14 of different shapes and sizes, ensuring tighter and smoother fitting.

[0049] In the forming process of paper cards, cutting machine 2, die cutting machine 3, creasing machine 4 and folding machine 5 are used in turn to ensure the accuracy of the size, shape and structure of the paper card. Not only improves the appearance quality of the product, but also enhances its physical properties. For paper cards with specific thickness, multiple original paper cards are stacked and fixed together by the laminating machine 1 to meet the preset thickness requirement, increasing the design flexibility.

[0050] In the coating of paper cards, suction oil meeting national standards and environmental protection standards is selected, and special coating equipment 7 is used for uniform coating, and then drying equipment 8 is used to accelerate the drying process, ensuring the quality of the coating and improving the reliability of the sealing.

[0051] In the sealing of paper cards and suction, high frequency current heating is used for sealing, which provides more stable and beautiful sealing effect than traditional double-sided adhesive, UV adhesive or hot melt adhesive, especially in the face of environmental changes. Some welding processes have good sealing effect on paper cards with thin thickness, but the sealing effect is poor for paper cards with thick thickness, while high frequency welding technology is more suitable for processing PVC and other suction materials, providing more reliable sealing effect, suitable for paper cards of various thicknesses, from thin sheets to thick sheets.

[0052] In terms of environmental protection, traditional adhesive materials may contain harmful substances, and the suction oil meeting national standards and environmental protection standards is selected in this application to ensure that the entire production process is green and pollution-free, and the high frequency welding technology used is a clean processing method that does not produce harmful by-products. At the same time, the sandwich type suction sealing form in this application is visually clear and beautiful, meeting the requirements of dustproof and wear-resistant products.

[0053] In terms of production efficiency, this application significantly improves production efficiency by coordinating the paper card forming mechanism, blister forming mechanism, and sealing packaging mechanism, thus meeting the needs of large-scale production. Through the cooperation of multiple pieces of equipment, the production process of combining paper cards and blister boxes 14 is optimized, solving the problems of weak sealing, unattractive appearance, and poor environmental performance in traditional processes, and significantly improving product quality and stability.

[0054] Example 2:

[0055] Combination Figure 4 and Figure 5 As shown, this embodiment is a sandwich paper card and blister sealing eyeglass case packaging structure, including a sandwich paper card 15 made by the paper card forming mechanism in embodiment one and a blister box 14 made by the blister forming mechanism. The inside of the blister box 14 is used to place eyeglass products.

[0056] like Figure 4 As shown, the sandwich-type paper card 15 in this application has symmetrical dimensions on both sides and can be folded along the crease line. One side is provided with an installation opening 12 for embedding the blister box 14, and the other side is provided with an easy-tear line 13 for easy tearing.

[0057] like Figure 5 As shown, the blister box 14 in this application has multiple protrusions for housing eyeglasses.

[0058] By setting installation openings 12 on both sides of the paper card and fitting them into the blister pack 14, a double-sided support structure is formed. The sandwich-type paper card 15 provides stronger support and avoids the problem of easy separation of single-sided paper cards. The double-sided fitting design improves the overall aesthetics of the packaging while enhancing its compression resistance and protective performance.

[0059] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
