[0028] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0029] In the following description, the example details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0030] It should be understood that when the terms "include" and / or "comprises" are used in this specification, they indicate the existence of the stated features, integers, steps, operations, elements or components, but do not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0031] In the existing technology, paper packaging or toys are made by combining multiple layers of sheet paper, which can ensure the strength and appearance of the finished product and further save costs. However, the requirements for children's toys are more stringent. The industry pays attention to the safety of children's use scenarios. If the weight of children's paper toys exceeds 400 grams, a water immersion test is required. It can be understood that within the specified time, the water immersion speed of children's paper toys needs to meet the standards, and they need to show no degumming, no damage and be able to maintain integrity. In order to meet the test requirements, in the existing technology, glue is applied to one side of the paper by screen printing, and then the paper is mounted and glued. However, in actual use, it is found that the above method has a high raw material cost of glue due to the need to completely apply glue on one side of the paper, and the diffusion rate of water in the water immersion test is slow, which is not conducive to production. Therefore, a more reasonable gluing scheme is urgently needed to solve the above-mentioned deficiencies.

[0032] In order to solve the above-mentioned technical problems, the present application provides a paper mounting gluing process, please refer to the attached Figure 1 To Attachment Figure 2The following steps are as follows: S1: obtaining a paper substrate; S2: forming a glue-dotting surface composed of a plurality of glue points distributed in a dot matrix on the surface of the paper substrate to obtain a glue-dotting paper material; S3: forming a fold line on the surface of the glue-dotting paper material, and mounting and pressing based on the fold line to obtain a laminated paper material folded and bonded by the glue-dotting surface;

[0033] By setting the glue surface responsible for pasting to be composed of multiple glue points, and arranging the multiple glue points in a point vibration manner, and forming interconnected water diffusion channels between the multiple glue points, a fast wetting effect can be obtained in the immersion test; this solution avoids the whole-surface gluing process of paper in traditional technology, saves a lot of raw materials, greatly reduces production costs, increases the diffusion speed of immersion, and further improves production efficiency.

[0034] In a more preferred solution, the shape of any glue point is circular. By designing the glue point to be circular, it is easy to process and shape, thereby reducing the difficulty of the process; the diameter of the glue point is 2-4mm, and the spacing between any two glues is 2-4mm. The preferred solution is that the diameter of the glue point is 4mm, and the spacing between any two glues is 2mm; in the above spacing setting, the strength of the stacked paper sheets under horizontal and vertical tension can be guaranteed. It is worth noting that the diameter of the glue point in this application is the same as that in the attached Figure 2 In order to further illustrate the effect of this solution, the traditional glue-covered process and the process of this application are experimentally compared. The specific comparison data are as shown in the attached Figure 2-3 It is not difficult to know from the contents of the attached drawings that the water absorption rate of the laminated paper products in this solution is 131-134% (119-121% in traditional technology), the average glue amount of the laminated paper products is 23g / m² (45g / m² in traditional technology), the horizontal tension of the laminated paper products is 2.0-2.4Lbs (2.2-2.6Lbs in traditional technology), and the vertical tension of the laminated paper products is 2.4-2.8Lbs (2.6-3.2Lbs in traditional technology). Although the tensile effect in the tensile test is not as good as the full glue solution in the traditional technology, it can also reach a qualified level. At the same time, the use of glue raw materials is indeed greatly saved, saving a lot of costs. At the same time, the laminated paper can also pass the immersion test faster, increasing the product preparation efficiency.

[0035] The present application also provides a gluing device for paper mounting, see Figure 5-7, used to perform the above method, including: a machine 1, a rubber printing roller 2 configured on the machine 1, a transfer layer 21 with a plurality of convex points arranged in a matrix on the cylinder surface of the rubber printing roller 2; the rubber printing roller 2 is used to form a dispensing surface on the surface of the paper substrate; the present scheme forms a dispensing surface on the paper substrate by means of the rubber printing roller, thereby achieving the effect described in the above process; in a specific scheme, the transfer layer is attached to the cylinder surface of the rubber printing roller, and the transfer layer is assembled in a pasting manner, which can facilitate technicians to assemble transfer layers arranged in arrays of different specifications; and the shape of the convex points matches the pattern on the dispensing surface, for example, the cross-sectional shape of any convex point is circular, and the diameter of the dot formed by the convex point is 2-4 mm, and the distance between any two convex points is 2-4 mm.

[0036] In this embodiment, the machine 1 is also provided with a feeding trough 3 for supplying glue to the printing rubber roller. It is not difficult to understand that, when working, the feeding trough contains glue, and the feeding trough 3 transports the glue to the printing rubber roller 2, so that during the rolling process, a glue point surface can be formed on the paper substrate through the transfer layer 21. The feeding trough can ensure the supply of glue, and thus ensure the stable operation of the glue point surface, and there will be no situation where a certain glue point fails to reach the expected amount of glue, thereby affecting the bonding performance.

[0037] In this embodiment, the two ends of the machine 1 form a feed end 11 and a discharge end 12, and are equipped with a conveying module 4; the conveying module 4 transports the paper substrate from the feed end 11 to the rubber printing roller 2 for processing to achieve the aforementioned S2 step, and after completion, it is further transported to the folding area, and after completion of folding and bonding, the stacked paper material is output from the discharge end; a clamping roller and a discharge table can also be added at the discharge end, the clamping roller will further compact the stacked paper material after folding, further increase the bonding ability of the glue, and the stacked paper material can be stored through the discharge table, which is convenient for technicians to carry out fixed-point transportation.

[0038] In this embodiment, the feed end 11 also includes a lifting plate (not shown) and a feeder structure (not shown) for transporting the paper substrate. Since the lifting plate and the feeder structure belong to the prior art, their structures and specific principles are not described in detail. Preferably, the conveying module 4 includes a chain push claw unit 41 and a suction belt unit 42, and the chain push claw unit 41 and the suction belt unit 42 are relatively arranged with the printing rubber roller 2 as the center. In actual production, the paper substrate is transported to the feeder mechanism via the lifting plate, and the cooperation of the feeder structure The chain push claw unit clamps the edge of the paper substrate, and the chain push claw unit transports the paper substrate according to the preset interval distance, thereby ensuring that the glue-inducing layer can process the surface of each paper substrate to form a glue-dotting surface to form a glue-dotting paper material. Subsequently, the glue-dotting paper material is adsorbed by the suction belt unit, thereby facilitating subsequent folding to achieve mounting and bonding; naturally, a cutting roller can also be set adjacent to the printing glue roller, and the cutting roller cuts the fold line pre-made on the paper substrate to form a semi-threading line, which is convenient for subsequent folding according to mounting.

[0039] In a more optimal solution, the machine 1 is further provided with a folding knife (not shown) in the area of ​​the suction belt unit, and the folding knife folds the glue-dot paper material, and after at least one folding, the laminated paper material of the present application can be obtained; the folding knife belongs to the prior art, so its structure and specific principles are not described in detail.

[0040] The advantages of the present invention are:

[0041] 1) By setting the glue surface responsible for pasting to be composed of multiple glue points, and arranging the multiple glue points in a point vibration manner, and forming interconnected water diffusion channels between the multiple glue points, the fastest wetting effect can be obtained in the immersion test; this solution avoids the whole-surface gluing process of paper in the traditional solution, saves a lot of raw materials, greatly reduces the production cost, increases the diffusion speed of immersion, and further improves the production efficiency;

[0042] 2) The transfer layer is pasted on the surface of the rubber printing roller. The transfer layer is assembled in a pasting manner, which makes it easy for technicians to assemble transfer layers arranged in arrays of different specifications;

[0043] 3) The glue-dot paper is adsorbed by the suction belt unit, which facilitates the subsequent folding to achieve mounting and bonding.

[0044] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
