Description

Technical Field

[0001] This invention relates to the field of paint-free paper application technology, specifically to a paint-free paper application device and application process. Background Technology

[0002] Melamine paper, also known as decorative paper or melamine paper, is an important component of melamine-faced boards. It plays a crucial role in the manufacturing process, giving the boards an attractive appearance and excellent performance. Melamine paper is a specially treated paper typically used on the surface of decorative boards. It is made by soaking the board in melamine resin adhesive, drying it to a certain degree of curing, and then laying it on particleboard, moisture-resistant board, medium-density fiberboard, plywood, blockboard, or other solid wood panels, followed by hot pressing to form a decorative board. The main purpose of melamine paper is to replace traditional painting processes, providing a beautiful surface decoration for boards while possessing excellent properties such as wear resistance, heat resistance, and chemical resistance.

[0003] Currently, the process of attaching paint-free paper to the surface of wood boards mainly involves manually feeding the paper, cutting it into pieces, placing it on the desired location, and then using a machine to press the paper onto the wood surface. However, this process has several drawbacks. Because the paint-free paper is thin and bulky, two people are needed simultaneously to pull the four corners of the paper from both sides to lay it neatly and flat on the wood surface. Each time the paper is laid, careful control of the placement is required. This operation results in low efficiency, high manual labor requirements, and a significant amount of manual work involved in the paint-free paper application process. Summary of the Invention

[0004] To address the problems in the existing technology, the present invention aims to provide a paint-free paper pasting device and pasting process, solving the problems described in the background art: Currently, the pasting of paint-free paper onto the surface of wood boards is mainly done manually by feeding the paper into pieces, placing them on the desired pasting position, and then pressing the paper onto the wood board surface using a machine. However, this pasting process has several drawbacks. Because the paint-free paper is thin and bulky, two people are needed simultaneously to pull the four corners of the paper from both sides to neatly lay it flat on the wood board surface. Furthermore, careful control of the placement position is required each time the paper is laid.

[0006] The top surface of the fixed base is fixedly mounted with several cylinder bases. Each cylinder base is fixedly mounted with a cylinder. Each cylinder has a piston rod extending forward. Each cylinder's piston rod has a support plate ear at its top. The bottom of the support plate ear is provided with a slide rail support plate. The slide rail support plate has a rubber pressure roller standing upright on its top surface. The rubber pressure roller is a round rod structure with a steel shaft at its internal axis. Each rubber pressure roller is located directly in front of the corresponding wooden board frame.

[0007] Each of the wooden board frames is equipped with a paper roll support above it. Each paper roll support is fixed to the top of the side support rib. A paper roll wheel is rotatably connected to the top of each paper roll support. The surface of the paper roll wheel is wound with paint-free paper. A paper roll conveyor wheel is provided below the paper roll wheel. The paper roll conveyor wheel has two mutually reversible wheels. The paint-free paper passes through the middle of the two mutually reversible wheels of the paper roll conveyor wheel and hangs downward.

[0008] As a preferred embodiment of the present invention, each of the wooden board grooves is provided with a plurality of air intake holes at equal intervals on its surface, and the side support ribs are provided with a plurality of air inlets on their surface, and the air intake holes and air inlets are connected inside the side support ribs.

[0009] As a preferred embodiment of the present invention, the slide rail support plate is configured as a semi-circular plate structure, the top of the slide rail support plate is provided with a raised arc-shaped slide rail, the surface of the slide rail is provided with an arc-shaped guide hole, the bottom end of the steel shaft is rotatably connected to a slider, the slider is slidably connected in the guide hole, and the bottom end of the steel shaft extends toward the bottom of the slide rail support plate.

[0010] As a preferred embodiment of the present invention, a traveling gear is installed at the bottom end of the steel shaft, and a protruding rack is provided at the bottom end of the slide rail support plate. The traveling gear meshes with the rack and rolls. The slide rail support plate is configured as a semi-circular plate structure with a servo motor fixedly installed at the center position. A swing wheel is provided on the surface of the servo motor, and a swing arm is provided on the surface of the swing wheel. The top end of the swing arm is rotatably connected to the bottom end of the steel shaft.

[0011] As a preferred embodiment of the present invention, a cutting blade is provided at the top of the rubber pressure roller, and the cutting blade is mounted on a steel shaft at the top of the rubber pressure roller.

[0012] This invention also provides a process for applying paint-free paper, which mainly includes the following steps:

[0013] S1. Enloading the paint-free paper: Load the paint-free paper onto the machine and pass it through the middle of the two counter-rotating wheels of the paper roll conveyor and hang it down to the preset height.

[0014] S2. Wood board installation: Apply adhesive evenly to the surface of the wood board beforehand, and then place the wood board with adhesive on the surface into each wood board groove in turn, and use several suction holes on the surface of the wood board groove to suction the wood board tightly.

[0015] S3, Pre-positioning of paint-free paper: The slide rail support plate moves forward through reciprocating sliding. At this time, the rubber pressure roller is located in the middle of the guide bend. The rubber pressure roller is used to gently press and attach the paint-free paper from the middle of the hanging downwards to the middle of the attached wooden board.

[0016] S4. Flattening the paint-free paper: The rubber pressure roller moves from the middle of the guide bend to one end of the guide bend. During the sliding process, the traveling gear rolls on the rack surface to support the rubber pressure roller to slide along the surface of the attached wooden board and rotate to roll. After the rubber pressure roller slides to one end of the guide bend, it returns to slide to the other end of the guide bend, so that the paint-free paper is flattened on the surface of the attached wooden board.

[0017] S5. Pre-cutting of the paint-free paper: After the rubber pressure roller presses and attaches the downward-hanging paint-free paper to the middle of the attachment board in step S3, the paint-free paper is subjected to the adhesive force of the attachment board and the pulling force of the paper roll conveyor wheel, causing the cutting blade at the top of the rubber pressure roller to cut into the surface of the paint-free paper.

[0018] S6. Segmentation of paint-free paper: In step S4, when the rubber pressure roller rolls from the middle of the guide bend hole to both ends of the guide bend hole, the cutting blade rolls and segments the surface of the paint-free paper.

[0019] S7. Retract the board and reload the paper: After the division in step S6 is completed, the rubber pressure roller retracts. At this time, the attached wooden board is removed from the wooden board groove. The paint-free paper on the paper roll is controlled by the paper roll conveyor roller to control the hanging height. Then repeat the above steps S1-S6 to complete the paint-free paper attachment to the new wooden board.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] I. The present invention has a fixed base that is horizontally fixed to the ground. A side support rib plate that stands upright on the top surface of the fixed base is fixedly installed on the top surface of the fixed base. Several wooden board frames are evenly spaced on the surface of the side support rib plate. The several wooden board frames can simultaneously hold multiple wooden boards to be coated with paint-free paper, realizing the simultaneous coating of paint-free paper on multiple wooden boards at one time, enabling mass production, high coating efficiency, and fast coating speed. Each wooden board frame is a semi-cylindrical structure, which is convenient to form an arc-shaped contour and can perfectly fit with the concave surface of the wooden board to be coated. It can better adsorb the wooden board to be coated from the concave surface, reducing the surface area of ​​the wooden board to be coated. Each wooden board frame has an arc-shaped recessed wooden board groove on its surface, which is convenient for positioning the coated wooden board and making it easy to accurately place the coated wooden board in the position. The coated wooden board to be coated is placed on the surface of the wooden board groove.

[0022] II. In this invention, each wooden board frame is equipped with a paper-winding roller at the top, with paint-free paper wound around its surface. Below the paper-winding roller is a paper-winding conveyor roller, which has two counter-rotating wheels. The paper is fed and positioned via the conveyor roller. The paint-free paper passes through the two counter-rotating wheels and hangs downwards, eliminating the need for manual handling of pre-cut paint-free paper and enabling automatic feeding of multiple wooden board frames. Several cylinder bases are fixedly mounted on the top surface of a fixed base, and a cylinder is fixedly mounted on the surface of each cylinder base. The cylinders push the rubber pressure rollers upright on the surface of the slide rail support plate to press the downward-hanging paint-free paper. At this point, the rubber pressure roller is positioned in the middle of the guide bend, exactly between the two sides of the hanging paint-free paper. The cylinder pushes the slide rail support plate forward gently, pressing the center of the paint-free paper lightly onto the center of the attached wooden board. Next, the rubber pressure roller moves from the middle of the guide bend towards one end of the guide bend. During the sliding process, the traveling gear rolls on the rack surface, supporting the rubber pressure roller to slide and rotate along the surface of the attached wooden board. After sliding to one end of the guide bend, the rubber pressure roller returns to the other end of the guide bend, so that the paint-free paper is completely wrapped around the surface of the attached wooden board and rolled flat.

[0023] Third, this invention presses and adheres the downward-hanging paint-free paper to the center of the attached wooden board using a rubber pressure roller. At this time, the paint-free paper is subjected to the adhesive force of the attached wooden board and the pulling force of the paper conveyor roller, causing the cutting blade at the top of the rubber pressure roller to cut into the surface of the paint-free paper. During the rolling process of the rubber pressure roller from the center of the guide bend hole to both ends of the guide bend hole, the cutting blade rolls and cuts the surface of the paint-free paper, thereby dividing and cutting the paint-free paper. It eliminates the need for manual cutting of the paint-free paper into pieces, the need for two people to simultaneously pull the four corners of the paint-free paper from both sides, and the need to neatly lay the paint-free paper flat on the surface of the wooden board. It also eliminates the need for careful control of the placement position during each laying of the paint-free paper.

[0024] Fourth, this invention allows the swing arm to easily control the steel shaft to be in the middle of the guide bend in the initial position. This enables the paint-free paper to be gently pressed and attached to the middle of the wood board for pre-positioning during the paint-free paper attachment process. Then, the pre-positioned rubber pressure rollers push and roll from the middle of the wood board to both sides, so that the paint-free paper is evenly attached from the middle of the wood board to the arc surfaces on both sides. This effectively reduces voids and air bubbles generated during the attachment process and improves the tightness of the attachment. Attached Figure Description

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0035] Example 1

[0036] Please see Figures 1-5 This is a schematic diagram of the overall structure of a paint-free paper application device and application process.

[0037] A paint-free paper pasting device includes a fixed base 5, which is horizontally fixed to the ground. A side support rib 1 is fixedly installed on the top surface of the fixed base 5. A number of wooden board frames 2 are evenly spaced on the surface of the side support rib 1. Each wooden board frame 2 has a relief groove 13 at its bottom. Each wooden board frame 2 is a semi-cylindrical structure. An arc-shaped recessed wooden board groove 4 is opened on the surface of each wooden board frame 2. The pasting wooden board 25 to be pasted is placed on the surface of the wooden board groove 4.

[0038] Several cylinder bases 9 are fixedly installed on the top surface of the fixed base 5. A cylinder 10 is fixedly installed on the surface of each cylinder base 9. A piston rod extends forward from each cylinder 10. A support plate ear 19 is provided at the top of the piston rod of each cylinder 10. A slide rail support plate 7 is provided at the bottom of the support plate ear 19. A rubber pressure roller 18 is provided on the surface of the slide rail support plate 7 and is upright on the top surface of the slide rail support plate 7. The rubber pressure roller 18 is a round rod structure. The internal axis of the rubber pressure roller 18 is a steel shaft 27. Each rubber pressure roller 18 is located in front of the corresponding wooden board frame 2.

[0039] Each wooden board frame 2 is equipped with a paper roll support 15 above it. Each paper roll support 15 is fixed to the top of the side support rib 1. Each paper roll support 15 is rotatably connected to a paper roll wheel 16 at its top. The surface of the paper roll wheel 16 is wound with paint-free paper 6. A paper roll conveyor wheel 17 is provided below the paper roll wheel 16. The paper roll conveyor wheel 17 has two mutually reversible wheels. The paint-free paper 6 passes through the middle of the two mutually reversible wheels of the paper roll conveyor wheel 17 and hangs down.

[0040] Specifically, in this embodiment, the fixed base 5 of the present invention is horizontally fixed to the ground. The top surface of the fixed base 5 is fixedly installed with a side support rib 1 that stands upright on the top surface of the fixed base 5. The surface of the side support rib 1 is provided with several wooden board frames 2 at equal intervals. The several wooden board frames 2 can simultaneously accommodate multiple wooden boards 25 to be covered with paint-free paper 6, realizing the simultaneous application of paint-free paper 6 to multiple wooden boards 25 at one time, enabling mass production, high application efficiency, and fast application speed. Each wooden board frame 2 is a semi-cylindrical structure, which is convenient to form an arc-shaped contour and can perfectly fit with the concave surface of the wooden board 25 to be covered. It can better adsorb the wooden board 25 to be covered from the concave surface, reducing the surface area of ​​the wooden board 25 to be covered. The surface of each wooden board frame 2 is provided with an arc-shaped recessed wooden board groove 4, which is convenient for positioning the wooden board 25 and making it easy to accurately place the wooden board 25. The surface of the wooden board groove 4 is on which the wooden board 25 to be covered is placed.

[0041] Each wooden board groove 4 has several air intake holes 14 evenly spaced on its surface, and the side support rib 1 has several air inlets 3 on its surface. The air intake holes 14 and air inlets 3 are connected inside the side support rib 1 and connected to an external air pump through the air inlets 3, which facilitates the control of air intake and exhaust of the air intake holes 14. At the same time, each wooden board frame 2 is a semi-cylindrical structure, which facilitates the formation of an arc-shaped profile and can perfectly fit the concave surface of the wooden board 25 to be attached, and can better adsorb the wooden board 25 to be attached from the concave surface.

[0042] The slide rail support plate 7 is designed as a semi-circular plate structure. The top of the slide rail support plate 7 is provided with a raised arc-shaped slide rail 8. The surface of the slide rail 8 is provided with an arc-shaped guide bend hole 21. The bottom end of the steel shaft 27 is rotatably connected to a slider 26. The slider 26 is slidably connected in the guide bend hole 21, which improves the smoothness of the steel shaft 27 during the reciprocating sliding process along the guide bend hole 21. The bottom end of the steel shaft 27 extends to the bottom of the slide rail support plate 7, thereby effectively improving the installation firmness of the steel shaft 27.

[0043] A traveling gear 24 is mounted on the bottom end of the steel shaft 27, and a protruding rack 20 is provided on the bottom end of the slide rail support plate 7. The traveling gear 24 meshes with the rack 20 and rolls. The slide rail support plate 7 is designed as a semi-circular plate structure, and a servo motor 12 is fixedly mounted at the center of the slide rail support plate 7. A swing wheel 23 is provided on the surface of the servo motor 12, and a swing arm 22 is provided on the surface of the swing wheel 23. The top end of the swing arm 22 is rotatably connected to the bottom end of the steel shaft 27. The swing wheel 23 is driven to rotate by the servo motor 12. The rotation of the swing wheel 23 causes the swing arm 22 to swing along the swing wheel 23. During the swinging process, the swing arm 22 pushes the steel shaft. 27 slides back and forth within the guide bend 21, thereby controlling the steel shaft 27 to swing back and forth along the guide bend 21. At the same time, the top of the swing arm 22 is rotatably connected to the bottom of the steel shaft 27. While the steel shaft 27 swings back and forth along the guide bend 21, the traveling gear 24 rolls on the surface of the rack 20 to support the rubber pressure roller 18 to slide and rotate along the surface of the attached wooden board 25. The rubber pressure roller 18 slides to one end of the guide bend 21 and then slides back to the other end of the guide bend 21, so that the paint-free paper 6 is completely wrapped on the surface of the attached wooden board 25 and is rolled flat.

[0044] Specifically, by swinging the swing arm 22, the steel shaft 27 is easily positioned in the middle of the guide bend 21 at the initial position. This allows for gentle pressing and placement of the paint-free paper 6 onto the middle of the adhesive board 25, thus pre-positioning the paint-free paper during the application process. Then, the pre-positioned rubber pressure roller 18 pushes and rolls the paint-free paper from the middle of the adhesive board 25 to both sides, ensuring that the paint-free paper is evenly applied from the middle of the adhesive board to the two curved surfaces. This effectively reduces voids and air bubbles generated during the application process and improves the tightness of the application.

[0045] A cutting blade 11 is provided at the top of the rubber pressure roller 18, and the cutting blade 11 is mounted on the steel shaft 27 at the top of the rubber pressure roller 18.

[0046] Specifically, in this embodiment, each wooden board frame 2 is provided with a paper-winding wheel 16 above it, and the surface of the paper-winding wheel 16 is wound with paint-free paper 6. A paper-winding conveyor wheel 17 is provided below the paper-winding wheel 16. The paper-winding conveyor wheel 17 has two mutually reversible wheels. The paper is fed and positioned by the paper-winding conveyor wheel 17. The paint-free paper 6 passes through the middle of the two mutually reversible wheels of the paper-winding conveyor wheel 17 and hangs down. There is no need for manual handling of the cut paint-free paper 6, realizing automatic feeding of multiple wooden board frames 2. Several cylinder 10 bases 9 are fixedly installed on the top surface of the fixed base 5. A cylinder 10 is fixedly installed on the surface of each cylinder 10 base 9. The cylinder 10 pushes the rubber pressure roller 18 upright on the surface of the slide rail 8 support plate 7 to press down and hang down. The paint-free paper 6 is hung up. At this time, the rubber pressure roller 18 is located in the middle of the guide bend 21, which is exactly in the middle of both sides of the downward hanging paint-free paper 6. The cylinder 10 pushes the slide rail 8 support plate 7 to move forward gently, pressing the middle of the paint-free paper 6 to adhere to the middle position of the attached wooden board 25. Next, the rubber pressure roller 18 moves from the middle position of the guide bend 21 to one end of the guide bend 21. During the sliding process, the traveling gear 24 rolls on the surface of the rack 20 to support the rubber pressure roller 18 to slide and rotate along the surface of the attached wooden board 25 and roll. The rubber pressure roller 18 slides to one end of the guide bend 21 and then slides back to the other end of the guide bend 21, so that the paint-free paper 6 is completely wrapped on the surface of the attached wooden board 25 and is rolled flat.

[0047] Specifically, in this embodiment, the present invention presses and attaches the downward-hanging paint-free paper 6 to the middle of the attachment board 25 by the rubber pressure roller 18. At this time, the paint-free paper 6 is subjected to the adhesive force of the attachment board 25 and the pulling force of the paper roll conveyor roller 17, causing the cutting blade 11 at the top of the rubber pressure roller 18 to cut into the surface of the paint-free paper 6. During the rolling process of the rubber pressure roller 18 from the middle of the guide bend 21 to both ends of the guide bend 21, the cutting blade 11 rolls and cuts the surface of the paint-free paper 6, thereby dividing and cutting the paint-free paper 6. It is not necessary to manually cut the paint-free paper 6 into pieces, nor is it necessary for two people to pull the four corners of the paint-free paper 6 from both sides at the same time to lay the paint-free paper 6 neatly on the surface of the board. It is not necessary to carefully control the placement position every time the paint-free paper 6 is laid.

[0053] S3, Pre-positioning of paint-free paper: The slide rail support plate 7 moves forward through reciprocating sliding. At this time, the rubber pressure roller 18 is located in the middle position of the guide bend 21. The rubber pressure roller 18 gently presses and attaches the paint-free paper 6 hanging downwards to the middle position of the attached wooden board 25.

[0054] S4. Flattening the paint-free paper: The rubber pressure roller 18 moves from the middle position of the guide bend 21 to one end of the guide bend 21. During the sliding process, the traveling gear 24 rolls on the surface of the rack 20 to support the rubber pressure roller 18 to slide and rotate along the surface of the attached wooden board 25. The rubber pressure roller 18 slides to one end of the guide bend 21 and then slides back to the other end of the guide bend 21, so that the paint-free paper is flattened on the surface of the attached wooden board 25.

[0055] S5. Pre-cutting of paint-free paper: After the rubber pressure roller 18 presses and attaches the downward-hanging paint-free paper 6 to the middle position of the attachment board 25 in step S3, the paint-free paper 6 is subjected to the adhesive force of the attachment board 25 and the pulling force of the paper roll conveyor roller 17, causing the cutting blade 11 at the top of the rubber pressure roller 18 to cut into the surface of the paint-free paper 6.

[0056] S6. Segmentation of paint-free paper: In step S4, when the rubber pressure roller 18 rolls from the middle of the guide bend 21 to both ends of the guide bend 21, the cutting blade 11 rolls and segments the surface of the paint-free paper 6.

[0057] S7. Retract the board and reload the paper: After the division in step S6 is completed, the rubber pressure roller 18 retracts. At this time, the attached wooden board 25 is removed from the wooden board groove 4.

The surface of the servo motor (12) is provided with a swing wheel (23), and the surface of the swing wheel (23) is provided with a swing arm (22). The top end of the swing arm (22) is rotatably connected to the bottom end of the steel shaft (27). The top of the rubber roller (18) is provided with a cutting blade (11), which is mounted on the steel shaft (27) at the top of the rubber roller (18).

2. The paint-free paper pasting device according to claim 1, characterized in that: Each of the wooden board grooves (4) has a number of air intake holes (14) evenly spaced on its surface, and the side support rib (1) has a number of air inlets (3) on its surface. The air intake holes (14) and the air inlets (3) are connected inside the side support rib (1).

3. The paint-free paper pasting device according to claim 2, characterized in that: A paint-free paper application process is also provided, which mainly includes the following steps: S1. Loading the paint-free paper: Load the paint-free paper (6) onto the machine and pass it through the middle of the two counter-rotating wheels of the paper roll conveyor (17) and hang it down to the preset height. S2, Wood board installation: Apply adhesive glue evenly to the surface of the attached wood board (25) beforehand, and then place the attached wood board (25) with adhesive glue on the surface into each wood board groove (4) in turn, and suck the attached wood board (25) tightly through several air suction holes (14) on the surface of the wood board groove (4). S3, Pre-positioning of paint-free paper: The slide rail support plate (7) moves forward by reciprocating sliding. At this time, the rubber pressure roller (18) is located in the middle of the guide bend (21). The rubber pressure roller (18) gently presses and attaches the paint-free paper (6) hanging downwards to the middle of the attached wooden board (25). S4. Flattening the paint-free paper: The rubber roller (18) moves from the middle position of the guide bend (21) to one end of the guide bend (21). During the sliding process, the traveling gear (24) rolls on the surface of the rack (20) to support the rubber roller (18) to slide and rotate along the surface of the attached wooden board (25). The rubber roller (18) slides to one end of the guide bend (21) and then returns to slide to the other end of the guide bend (21), so that the paint-free paper is flattened on the surface of the attached wooden board (25). S5, Pre-cutting of paint-free paper: In step S3, the rubber pressure roller (18) presses and attaches the downward-hanging paint-free paper (6) to the middle position of the attachment board (25). At this time, the paint-free paper (6) is subjected to the adhesive force of the attachment board (25) and the pulling force of the paper roll conveyor roller (17), causing the cutting blade (11) at the top of the rubber pressure roller (18) to cut into the surface of the paint-free paper (6). S6, Segmentation of paint-free paper: In step S4, when the rubber roller (18) rolls from the middle of the guide bend (21) to both ends of the guide bend (21), the cutting blade (11) rolls and segments the surface of the paint-free paper (6). S7. Retract the board and reload the paper: After the division in step S6 is completed, the rubber pressure roller (18) retracts. At this time, the attached wooden board (25) is removed from the wooden board groove (4). The paint-free paper (6) on the paper roll (16) is controlled by the paper roll conveyor roller (17) to control the hanging height. Then repeat the above steps S1-S6 to complete the attachment of the paint-free paper (6) to the new wooden board.
