Description

Technical Field

[0001] The present invention relates to the technical field of decorative base paper laying, and in particular to a decorative base paper laying device. Background Art

[0002] Currently, the artificial decorative wood board industry has formed a complete industrial chain from substrate handling to hot pressing and forming. The industry generally uses melamine impregnated paper as the decorative material, and its hot pressing and laminating process can form a wear-resistant layer on the wood board surface. However, the base paper laying link still highly relies on manual labor. According to industry association statistics, a single production line needs to process 2,000 - 3,000 substrates per day on average. The manual laying speed is about 15 seconds per sheet, and the rejection rate due to positioning errors is as high as 3% - 5%. With the implementation of environmental protection regulations such as the "Emission Standard for Pollutants in the Wood-Based Panel Industry", the production capacity of traditional solid wood boards has been continuously compressed, further stimulating the demand for automation transformation.

[0003] Upon investigation, the publication number: CN115179374B discloses "a decorative base paper laying device and method". In this technology, it is disclosed that "it includes a walking beam ground rail, a walking drive assembly, a Z-axis adjustment bracket, and a rotatable cantilever suction cup shaft assembly. A walking drive assembly is arranged above the walking beam ground rail, a Z-axis adjustment bracket is arranged on the walking drive assembly, and a rotatable cantilever suction cup shaft assembly is arranged above the Z-axis adjustment bracket. Ground rail base assemblies are arranged on both sides of the walking beam ground rail. The present invention is installed on one side of the existing base paper lifting bracket and the board surface paving table, and the rotatable cantilever suction cup shaft assembly covers the entire range of the existing base paper lifting bracket and the board surface paving table. Without changing the process flow of the existing production process, the upgrade and transformation of this process can be achieved, and there is no need to additionally occupy production space. Only the ground rail needs to be laid in the existing manual operation passage, and it has technical effects such as completely replacing manual labor, a more stable production rhythm, not affecting the efficiency of the overall production line, and reducing defective products"; However, currently, the mechanized laying solutions in the industry are mainly of two types: ① Semi-automatic vacuum adsorption device, which transfers the base paper through a negative pressure suction cup, but a visual positioning system needs to be supported (about 800,000 yuan per set of equipment); ② The HPL automatic paving line developed by the German Homag Group (the quotation exceeds 2 million yuan), which integrates a manipulator and an infrared correction system, but the layout of the entire production line needs to be reconstructed. Although the efficiency of these two solutions is increased by 30%, the equipment procurement and transformation costs exceed the affordability of small and medium-sized enterprises. Although the imported automation equipment can reach an accuracy of ±0.5 mm, it has three major drawbacks: the equipment procurement cost is too high, the production line needs to be shut down for transformation, and maintenance depends on foreign engineers. If the manual laying solution is adopted, 2 - 3 workers are required to cooperate to complete the alignment and paper laying. The labor cost accounts for 18% of the total cost of the entire production line, and there are defects in manual laying such as poor positioning accuracy (±3 mm), high labor intensity (repeated bending operations are required), and unstable production efficiency (affected by the proficiency of workers). Although the initial investment is low, the long-term labor cost is high; To solve the above problems, a decorative base paper laying device is proposed in this application. Summary of the Invention

[0004] (I) Technical problems to be solved In view of the deficiencies of the prior art, the present invention provides a decorative base paper laying device, which solves the problems of high reject rate caused by insufficient positioning accuracy during manual laying of base paper and poor compatibility between existing automated equipment and production lines, as well as excessive transformation costs.

[0005] (II) Technical solutions To achieve the above objectives, the present invention is realized through the following technical solutions: A decorative base paper laying device includes a guide rail and a frame. The frame is installed on the guide rail. A cross bar is fixedly connected to the upper surface of the frame. A pressing rod is rotatably connected to the side surface of the cross bar.

The inside of the V-shaped spreading plate is fixedly connected to the connecting plate. The upper surface of the connecting plate is fixedly connected to the sliding rod; A sliding plate is provided inside the frame. A pressing edge assembly is provided on the lower surface of the sliding plate. The pressing edge assembly includes a cutting disc, a first rotating shaft and a first roller. The inside of the cutting disc is fixedly connected to the first rotating shaft. The side surface of the first rotating shaft is fixedly connected to the first roller; A guiding assembly is provided on the lower surface of the frame. The guiding assembly includes an L-shaped guiding block, a wedge-shaped pressed block, a second sliding column, a second sliding sleeve and a second spring. The inside of the L-shaped guiding block is fixedly connected to the second sliding sleeve. The inner wall of the second sliding sleeve is slidably connected to the second sliding column. The upper end of the second sliding column is fixedly connected to the wedge-shaped pressed block. The upper end of the second spring is fixedly connected to the wedge-shaped pressed block. The lower end of the second spring is fixedly connected to the L-shaped guiding block. The second sliding column and the second sliding sleeve both pass through the inside of the second spring.

[0006] Preferably, a limiting rod is fixedly connected to the upper end of the sliding rod. A limiting groove is provided inside the pressing rod. The limiting rod is adapted to the limiting groove.

One end of the third spring away from the upper connecting block is fixedly connected to a lower connecting block. By inserting the limiting block into the guide column and then rotating the threaded sleeve, the lower connecting block presses the limiting block, so that the decorative base paper on the paper roller is pressed against the ground, and rotating the threaded sleeve can adjust the pressing force.

[0013] Preferably, a third sliding column is fixedly connected to the lower surface of the upper connecting block. A third sliding sleeve is slidably connected to the side surface of the third sliding column. One end of the third sliding sleeve away from the third sliding column is fixedly connected to the lower connecting block. The lower surface of the lower connecting block is in contact with the limiting block. The upper connecting block and the lower connecting block are limited by the third sliding column and the third sliding sleeve, so that the process of approaching or separating from each other is more stable.

[0014] Preferably, a second rotating shaft is rotatably connected to the inside of the frame body. Third rollers are fixedly connected to both ends of the second rotating shaft. The third rollers are in contact with the ground and roll, which facilitates pushing.

The reaction force generated when the second spring 23 is in a compressed state can press down the frame body 2, making the forward process more stable.

[0023] Working principle: As Figure 1 、 Figure 2 、Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, for a decorative base paper laying device, during use, first clean the ground, then align the L-shaped guide block 19 with the guide rail 1 and insert it. The wedge-shaped pressure block 20 is first pressed and then slides. At this time, the second spring 23 is in a compressed state, and the generated reaction force presses down the second sliding sleeve 22, so that the third roller 37 can tightly press the ground, thereby improving the positioning accuracy during manual laying of the base paper, reducing the waste rate, and enabling the frame 2 to be quickly installed on the guide rail 1, shortening the installation time to improve work efficiency. Then insert the limit blocks 29 at both ends of the paper roll 30 into the guide posts 28, and then insert the upper connecting block 32 and the lower connecting block 33 into the guide posts 28.

Hold the push rod 25 by hand and push the tripod 24. During the pushing process of the tripod 24, the pressure rod 4 is driven to press down the sliding rod 7 and the second roller 27. At the same time, the device starts to move forward along the guide rail 1. The sliding rod 7 presses down the V-shaped spreading plate 5 to spread the decorative base paper during the laying process, making it not easy to wrinkle. The second roller 27 drives the slide plate 10 to press the cutting disc 11 and the first roller 13 against the edge of the decorative base paper, so that the edge of the decorative base paper is pressed and cut, achieving the effect of simultaneous flattening, edge pressing, and cutting, making it not easy to curl or warp during the laying process, greatly optimizing the laying process, not only improving the laying quality but also improving work efficiency. And the manual pushing method improves the compatibility between the automated equipment and the production line and reduces the equipment transformation cost.
