Description

Technical Field

[0001] This invention relates to the field of decorative base paper laying technology, and in particular to a decorative base paper laying device. Background Technology

[0002] The current engineered wood panel industry has formed a complete industrial chain from substrate handling to hot-pressing. The industry generally uses melamine-impregnated paper as the surface material, and its hot-pressing process creates a wear-resistant layer on the surface of the wood panel. However, the paper laying process still heavily relies on manual labor. According to industry association statistics, a single production line needs to process 2,000-3,000 substrates per day, with a manual laying speed of approximately 15 seconds per substrate. Furthermore, the scrap rate due to positioning errors is as high as 3%-5%. With the implementation of environmental regulations such as the "Emission Standard for Pollutants from the Engineered Wood Panel Industry," the production capacity of traditional solid wood panels continues to shrink, further stimulating the demand for automation upgrades.

[0003] According to the public announcement (CN115179374B), a "Decorative Paper Laying Device and Method" is disclosed. This technology discloses "a walking beam ground rail, a walking drive component, a Z-axis adjustment bracket, and a rotatable cantilever suction cup shaft assembly. The walking drive component is arranged above the walking beam ground rail, the Z-axis adjustment bracket is arranged on the walking drive component, and the 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. This invention is installed on one side of the existing paper lifting bracket and board laying platform, and the rotatable cantilever suction cup shaft assembly covers the entire area of ​​the paper lifting bracket and board laying platform. Without changing the existing production process, this invention upgrades and transforms the process, and does not require additional production space. It only requires laying a ground rail in the existing manual operation channel. It has the technical effects of completely replacing manual labor, providing a more stable production rhythm, not affecting the overall production line efficiency, and reducing defective products."

[0004] However, the current mechanized paper laying solutions in the industry mainly fall into two categories: ① Semi-automatic vacuum adsorption devices, which transfer the base paper through negative pressure suction cups, but require a visual positioning system (a single set of equipment costs approximately 800,000 yuan); ② The HPL automatic paper laying line developed by the German HOMAG Group (priced at over 2 million yuan), which integrates robotic arms and infrared correction systems, but requires a complete restructuring of the entire production line layout. Although these two solutions improve efficiency by 30%, the equipment purchase and modification costs exceed the affordability of small and medium-sized enterprises. Imported automated equipment, although achieving an accuracy of ±0.5mm, has three major drawbacks: excessively high equipment purchase costs, the need to shut down and modify the production line, and reliance on foreign engineers for maintenance. If a manual paper laying solution is adopted, 2-3 workers are required to work together to complete the alignment and paper laying, with labor costs accounting for 18% of the total production line cost. Furthermore, manual paper laying suffers from poor positioning accuracy (±3mm), high labor intensity (requiring repeated bending over), and unstable production efficiency (affected by worker skill level). Although the initial investment is low, the long-term labor costs are high.

[0005] To address the aforementioned problems, this application proposes a decorative base paper laying device. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides a decorative base paper laying device, which solves the problems of high scrap rate caused by insufficient positioning accuracy when laying base paper manually, as well as poor compatibility between existing automated equipment and production lines and excessive modification costs.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a decorative base paper laying device, comprising a guide rail and a frame, wherein the frame is mounted on the guide rail, a crossbar is fixedly connected to the upper surface of the frame, a pressure bar is rotatably connected to the side surface of the crossbar, and a leveling component is provided at the end of the pressure bar away from the crossbar, the leveling component comprising a V-shaped spreading plate, a connecting plate and a sliding rod, wherein the interior of the V-shaped spreading plate is fixedly connected to the connecting plate, and the upper surface of the connecting plate is fixedly connected to the sliding rod;

[0010] The frame is equipped with a sliding plate inside, and a pressing assembly is provided on the lower surface of the sliding plate. The pressing assembly includes a cutting disc, a first rotating shaft, and a first roller. The interior of the cutting disc is fixedly connected to the first rotating shaft, and the side surface of the first rotating shaft is fixedly connected to the first roller.

[0011] The lower surface of the frame is provided with a guide assembly, which includes an L-shaped guide block, a wedge-shaped pressure block, a second sliding column, a second sliding sleeve, and a second spring. The interior of the L-shaped guide 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 pressure block, the upper end of the second spring is fixedly connected to the wedge-shaped pressure block, and the lower end of the second spring is fixedly connected to the L-shaped guide block. The second sliding column and the second sliding sleeve both pass through the interior of the second spring.

[0012] Preferably, a limiting rod is fixedly connected to the upper end of the slide rod, and a limiting groove is provided inside the pressure rod, with the limiting rod and the limiting groove being compatible. Through the cooperation of the limiting rod and the limiting groove, the pressure rod can drive the slide rod to press the V-shaped spreading plate vertically downwards, thus making the process of the V-shaped spreading plate fitting more closely to the ground and sandwiching the decorative paper more securely, preventing scratches or tears to the decorative paper.

[0013] Preferably, a connecting block is rotatably connected to the end of the first rotating shaft away from the cutting disc, and the upper surface of the connecting block is fixedly connected to the sliding plate. The number of edge-pressing components is two, symmetrically distributed left and right. By symmetrically arranging the edge-pressing components, both sides of the decorative base paper can be pressed down by the first roller while being cut by the cutting disc, thereby reducing the curling and rough edges of the laid decorative base paper and ensuring a tight fit with the ground.

[0014] Preferably, the upper surface of the slide plate is symmetrically provided with elastic components. Each elastic component includes a first sliding sleeve, a first sliding column, and a first spring. The lower end of the first sliding sleeve is fixedly connected to the slide plate, and the interior of the first sliding sleeve is slidably connected to the first sliding column. The end of the first sliding column away from the first sliding sleeve is fixedly connected to the frame. The upper end of the first spring is fixedly connected to the frame, and the end of the first spring away from the frame is fixedly connected to the slide plate. Both the first sliding sleeve and the first sliding column pass through the interior of the first spring. The interior of the frame is provided with a sliding groove, and both ends of the slide plate are slidably connected to the sliding groove. When not in use, the elastic components pull the edge-pressing component upwards, preventing the cutting disc and the first roller from contacting the decorative paper and the ground, thus providing protection and extending the service life of the equipment.

[0015] Preferably, the number of guide components is four, arranged in a rectangular array. The upper surface of the L-shaped guide block is fixedly connected to the frame, and the end of the L-shaped guide block away from the frame is slidably connected to the guide rail. With these four guide components, during the process of pushing the frame into the guide rail, the two opposing L-shaped guide blocks can quickly engage the guide rail, facilitating installation. Simultaneously, the slope of the wedge-shaped pressure block, after being compressed, enters the inner wall of the guide rail and slides with it. The reaction force generated by the compressed spring No. 2 can press the frame down, making the forward movement more stable.

[0016] Preferably, a tripod is fixedly connected to the upper surface of the pressure rod, and a push rod is fixedly connected to the upper end of the tripod. By pushing the push rod, the tripod can press down on the pressure rod, causing the pressure rod to rotate around the axis of the crossbar and press down on the sliding rod. This allows the push rod to not only drive the frame forward along the guide rail, but also to simultaneously press down the flattening component and the pressing edge component.

[0017] Preferably, a support block is fixedly connected to the upper surface of the slide plate, and a second roller is rotatably connected inside the support block. The side surface of the second roller contacts the pressure rod. By pressing down the pressure rod, the second roller is driven to press down the leveling component under the slide plate.

[0018] Preferably, guide posts are symmetrically distributed on the upper surface of the frame. Limiting blocks are fitted onto the side surfaces of the guide posts. A paper roller is rotatably connected inside the limiting blocks. A threaded sleeve is threadedly connected to the upper end of each guide post. An upper connecting block is rotatably connected to the lower end of the threaded sleeve. A No. 3 spring is fixedly connected to the lower surface of the upper connecting block. A lower connecting block is fixedly connected to the end of the No. 3 spring away from the upper connecting block. By inserting the limiting block into the guide post and then rotating the threaded sleeve, the lower connecting block presses against the limiting block, thereby pressing the decorative paper on the paper roller against the ground. Rotating the threaded sleeve adjusts the pressing force.

[0019] Preferably, a third sliding post 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 post, the end of the third sliding sleeve away from the third sliding post is fixedly connected to the lower connecting block, and the lower surface of the lower connecting block is in contact with the limiting block. The third sliding post and the third sliding sleeve limit the movement of the upper and lower connecting blocks, making them more stable as they move closer or further apart.

[0020] Preferably, the frame is internally rotatably connected to a second rotating shaft, and both ends of the second rotating shaft are fixedly connected to a third roller. The third roller contacts the ground and rolls, facilitating movement.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the present invention provides a technical solution: a decorative base paper laying device, including a guide rail 1 and a frame 2. The frame 2 is installed on the guide rail 1. A crossbar 3 is fixedly connected to the upper surface of the frame 2. A pressure rod 4 is rotatably connected to the side surface of the crossbar 3. A leveling component is provided at the end of the pressure rod 4 away from the crossbar 3. The leveling component includes a V-shaped spreading plate 5, a connecting plate 6, and a sliding rod 7. The interior of the V-shaped spreading plate 5 is fixedly connected to the connecting plate 6. The upper surface of the connecting plate 6 is fixedly connected to the sliding rod 7. A limiting rod 8 is fixedly connected to the upper end of the sliding rod 7. A limiting groove 9 is provided inside the pressure rod 4. The limiting rod 8 and the limiting groove 9 are adapted to each other. Through the cooperation of the limiting rod 8 and the limiting groove 9, the pressure rod 4 can drive the sliding rod 7 to press the V-shaped spreading plate 5 vertically downward, so that the V-shaped spreading plate 5 fits more closely to the ground when sandwiching the decorative paper, making it less likely to scratch or tear the decorative paper. The upper surface of the pressure rod 4 is fixedly connected to the tripod 24, and the upper end of the tripod 24 is fixedly connected to the push rod 25. By pushing the push rod 25, the tripod 24 can press down the pressure rod 4, so that the pressure rod 4 rotates around the axis of the crossbar 3 and presses down the sliding rod 7. Thus, pushing the push rod 25 can not only drive the frame 2 forward along the guide rail 1, but also press down the flattening component and the pressing edge component at the same time. The upper surface of the slide plate 10 is fixedly connected to the support block 26, and the inside of the support block 26 is rotatably connected to the second roller 27. The side surface of the second roller 27 is in contact with the pressure rod 4. The pressure rod 4 is pressed down to drive the second roller 27 to press down the flat component under the slide plate 10. The upper surface of the frame 2 is symmetrically distributed with guide posts 28. The side surface of the guide post 28 is fitted with a limiting block 29. The inside of the limiting block 29 is rotatably connected to a paper roller 30. The upper end of the guide post 28 is threadedly connected to a threaded sleeve 31. The lower end of the threaded sleeve 31 is rotatably connected to an upper connecting block 32. The lower surface of the upper connecting block 32 is fixedly connected to a third spring 38. The end of the third spring 38 away from the upper connecting block 32 is fixedly connected to a lower connecting block 33. By inserting the limiting block 29 into the guide post 28 and then rotating the threaded sleeve 31, the lower connecting block 33 presses against the limiting block 29, thereby pressing the decorative paper on the paper roller 30 against the ground. Rotating the threaded sleeve 31 can adjust the pressing force. The lower surface of the upper connecting block 32 is fixedly connected to the third sliding post 34, and the side surface of the third sliding post 34 is slidably connected to the third sliding sleeve 35. The end of the third sliding sleeve 35 away from the third sliding post 34 is fixedly connected to the lower connecting block 33, and the lower surface of the lower connecting block 33 is in contact with the limiting block 29. The third sliding post 34 and the third sliding sleeve 35 limit the upper connecting block 32 and the lower connecting block 33, making them more stable when they move closer or further apart. The inside of the frame 2 is rotatably connected to the second rotating shaft 36, and both ends of the second rotating shaft 36 are fixedly connected to the third roller 37. The third roller 37 contacts the ground and rolls, making it easy to push.

[0036] The frame 2 has a slide plate 10 inside, and the lower surface of the slide plate 10 has a pressing component. The pressing component includes a cutting disc 11, a first rotating shaft 12 and a first roller 13. The inside of the cutting disc 11 is fixedly connected to the first rotating shaft 12, and the side surface of the first rotating shaft 12 is fixedly connected to the first roller 13. The end of the first rotating shaft 12 away from the cutting disc 11 is rotatably connected to a connecting block 14. The upper surface of the connecting block 14 is fixedly connected to the slide plate 10. There are two pressing components, which are symmetrically distributed on the left and right. By symmetrically arranging the edge pressing components, the two sides of the decorative paper can be pressed by the first roller 13 and cut by the cutting disc 11, thereby reducing the curling and rough edges of the decorative paper after laying, and making it fit tightly to the ground. The upper surface of the slide plate 10 is symmetrically equipped with elastic components, which include a first sliding sleeve 15, a first sliding column 16 and a first spring 17. The lower end of the first sliding sleeve 15 is fixedly connected to the slide plate 10, and the interior of the first sliding sleeve 15 is slidably connected to the first sliding column 16. The end of the first sliding column 16 away from the first sliding sleeve 15 is fixedly connected to the frame 2. The upper end of the first spring 17 is fixedly connected to the frame 2, and the end of the first spring 17 away from the frame 2 is fixedly connected to the slide plate 10. The first sliding sleeve 15 and the first sliding column 16 both pass through the interior of the first spring 17. The interior of the frame 2 is provided with a sliding groove 18, and both ends of the slide plate 10 are slidably connected to the sliding groove 18. When not in use, the elastic component pulls the edge pressing component upward, preventing the cutting disc 11 and the first roller 13 from contacting the decorative paper and the ground, thus providing protection and extending the service life of the equipment.

[0037] The lower surface of the frame 2 is provided with a guide assembly, which includes an L-shaped guide block 19, a wedge-shaped pressure block 20, a second sliding column 21, a second sliding sleeve 22, and a second spring 23. The interior of the L-shaped guide block 19 is fixedly connected to the second sliding sleeve 22. The inner wall of the second sliding sleeve 22 is slidably connected to the second sliding column 21. The upper end of the second sliding column 21 is fixedly connected to the wedge-shaped pressure block 20. The upper end of the second spring 23 is fixedly connected to the wedge-shaped pressure block 20. The lower end of the second spring 23 is fixedly connected to the L-shaped guide block 19. The second sliding column 21 and the second sliding sleeve 22 both pass through the interior of the second spring 23. There are four guide assemblies, which are distributed in a rectangular array. The upper surface of the L-shaped guide block 19 is fixedly connected to the frame 2. The end of the L-shaped guide block 19 away from the frame 2 is slidably connected to the guide rail 1. With the help of four guide components, during the process of pushing the frame 2 into the guide rail 1, the two L-shaped guide blocks 19 set in opposite directions can quickly snap the guide rail 1 into place, which is convenient for installation. At the same time, the slope of the wedge-shaped pressure block 20 is pressed and enters the inner wall of the guide rail 1 and slides with it. The reaction force generated by the second spring 23 in the compressed state can press the frame 2 down, making the forward movement more stable.

[0038] Working principle:

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this decorative paper laying device, when in use, first clean the ground, then insert the L-shaped guide block 19 into the guide rail 1. 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 resulting reaction force presses down the second sliding sleeve 22, so that the third roller 37 can press tightly against the ground. This improves the positioning accuracy when manually laying the paper, reduces the scrap rate, and allows the frame 2 to be quickly installed on the guide rail 1, shortening the installation time and improving work efficiency. Then, the limiting blocks 29 at both ends of the paper roller 30 are inserted into the guide post 28, and the upper connecting block 32 and the lower connecting block 33 are inserted into the guide post 28. The threaded sleeve 31 is rotated to adjust the elasticity of the third spring 38, thereby adjusting the pressure of the paper roller 30 on the ground. After the installation is completed, the decorative paper on the paper roller 30 is... The device is sandwiched between the V-shaped spreading plate 5 and the cleaned ground. By holding the push rod 25 and pushing the tripod 24, the tripod 24 drives the pressure rod 4 to press down the sliding rod 7 and the second roller 27. At the same time, the device begins to move forward along the guide rail 1. The sliding rod 7 presses down the V-shaped spreading plate 5 to spread the decorative paper out during the laying process, making it less prone to wrinkles. The second roller 27 drives the sliding plate 10 to press the cutting disc 11 and the first roller 13 onto the edge of the decorative paper, thereby pressing and cutting the edge of the decorative paper. This achieves the effect of flatness, edge pressing and cutting simultaneously, making it less likely for curling or warping to occur during the laying process. This greatly optimizes the laying process, not only improving the laying quality but also increasing work efficiency. Furthermore, the manual pushing method improves the compatibility of automated equipment with the production line and reduces the equipment modification cost.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
