Description

Technical Field

[0001] This invention belongs to the field of sheet metal processing technology, and in particular relates to an automatic gluing assembly and edge sealing equipment and method for composite skin sheets. Background Technology

[0002] Composite paneling is widely used in furniture making, building materials processing, and other fields. In the processing of these panels, the adhesive application at the edge banding is one of the key steps. The quality of the adhesive application directly affects the strength and lifespan of the edge banding, thus impacting the quality of the final product. Currently, the industry mostly uses adhesive application equipment to treat the edge banding of panels. Adhesive rollers apply glue to the panel surface, which is then combined with the application of edge banding tape to complete the edge banding operation. With the expansion of production scale, companies are constantly increasing their requirements for adhesive application efficiency and quality, and various adhesive application equipment are continuously being adjusted and optimized in practical applications.

[0003] When using existing gluing equipment, some boards have gaps on the sides, which often leads to uneven gluing. In some cases, the gluing rollers do not make sufficient contact with the board, preventing the glue from penetrating into the gaps on the board surface. These problems together result in large fluctuations in gluing quality, making it difficult to meet the stable quality requirements of mass production. Therefore, an automatic gluing component for composite skin panels is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic glue application component and edge sealing equipment and method for composite skin panels, which enables the glue to be brushed into the gaps, improves the glue application quality and efficiency, and solves the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] The automatic adhesive application assembly for composite skin panels includes:

[0007] A glue box is set at the bottom of the base frame. A second glue-applying roller is rotatably connected to the surface of the base frame. The middle of the second glue-applying roller is located inside the glue box and its bottom is in contact with the glue. Slides are provided on both sides of the glue box. A first slider is slidably connected in each slide. A first glue-applying roller is rotatably connected between the two first sliders. The first glue-applying roller and the second glue-applying roller are at the same height.

[0008] The top of the glue box is fixedly connected to two symmetrically arranged tracks. A second slider is slidably connected in each of the two tracks. A second mounting bracket is slidably connected between the second sliders. A brush plate is fixedly connected to the top of the second mounting bracket. The brush plate is located between the first glue-applying roller and the second glue-applying roller.

[0009] A first motor is fixedly connected to one side of the base frame, and one end of the output shaft of the first motor is fixed to the second glue-applying roller;

[0010] Two first drive units are respectively set on one side of the two first sliders to drive the first glue-applying roller to pre-apply glue to the board;

[0011] The second drive unit is located on both sides of the brush plate and is used to drive the brush plate to move and introduce adhesive into the gaps in the board.

[0012] Furthermore, the first drive unit includes a fixed shaft, which is rotatably connected to one side of the glue tank. Gears are fixedly connected to both the circumference of the fixed shaft and the circumference of the second glue-applying roller, and the two gears mesh. A drive disk is fixedly connected to one end of the fixed shaft, and a drive shaft is eccentrically fixed to one side of the drive disk. A connecting rod is rotatably connected between the drive shaft and the first slider on the same side.

[0013] Furthermore, the second drive unit includes a connecting frame, which is fixed to one side of the second slider and the other end is fixed to the first slider on the same side.

[0014] Furthermore, the surface of the glue box is fixedly connected to two baffles. One side of one baffle is fixedly connected to multiple arc-shaped protrusions installed side by side. One end of the second mounting bracket abuts against the protrusions, and the other end of the second mounting bracket slides through the other baffle and is fixedly installed with a tension spring between them.

[0015] Furthermore, a scraper is bolted to the top of the glue box, and the scraper is located on one side of the second glue-applying roller to remove excess glue from the surface of the second glue-applying roller.

[0016] Furthermore, a third mounting bracket is fixedly connected to one side of the base frame, a feeding roller is rotatably connected to one side of the third mounting bracket, a second motor is fixedly connected to one side of the third mounting bracket, one end of the output shaft of the second motor is fixed to the feeding roller, a first mounting bracket is fixedly connected to the bottom of the base frame, and a first pressure roller is fixed to one side of the first mounting bracket by bolts. The first pressure roller is located on one side of the feeding roller and is used to convey the edge sealing tape.

[0017] The present invention also proposes an edge banding device, including an automatic glue application assembly for composite skin panels, and further including multiple support rollers and multiple limiting rollers. The multiple support rollers rotate on the top of the base frame to support the panels, and the multiple limiting rollers rotate on one side of the first side frame to limit the position of the panels.

[0018] A conveying mechanism is disposed on the surface of the base frame for conveying sheet metal;

[0019] A pressing mechanism is provided on one side of the first side frame for pressing the sheet metal.

[0020] Furthermore, the conveying mechanism includes a second side frame fixed to the top of the base frame. A sliding frame is slidably connected to one side of the second side frame. Multiple mounting shafts are rotatably connected to the top of the sliding frame. A drive roller is fixedly connected to the top of each mounting shaft. A through screw is threaded to one side of the second side frame. The other end of the screw is rotatably connected to the sliding frame. Adjacent mounting shafts are connected by synchronous pulleys and synchronous belts. A third motor is fixedly connected to the bottom of the sliding frame. One end of the output shaft of the third motor is fixed to one of the mounting shafts.

[0021] Furthermore, the pressing mechanism includes a side plate fixed to one side of the first side frame, a pressure frame slidably connected to the bottom of the side plate, a plurality of second pressure rollers rotatably connected to the bottom of the pressure frame, and a cylinder fixedly connected to the top of the side plate, with one end of the cylinder piston rod fixed to the pressure frame.

[0022] This invention also proposes an edge-sealing method for edge-sealing equipment, comprising the following steps:

[0023] S1: The edge sealing tape passes through the bottom of the base frame and is then fed between the feeding roller and the first pressure roller. By starting the second motor, the feeding roller rotates and cooperates with the first pressure roller to convey the edge sealing tape.

[0024] S2: The plate is placed on the support roller. When it enters the side of the drive roller, the sliding frame is moved by rotating the screw, so that the drive roller comes into contact with the plate. At the same time, the cylinder pushes the second pressure roller to move downward, so that it presses the plate. The third motor is started, and the friction force is used to make the drive roller move the plate.

[0025] S3: When feeding, start the first motor, which drives the second glue-applying roller to rotate, thereby applying the glue in the glue tank to one side of the board edge. At the same time, the board comes into contact with the first glue-applying roller, and the friction causes it to rotate, thereby driving the glue to pre-contact the board and the glue, so that the glue can better penetrate into the side of the board. At the same time, when the board passes through the brush board, the brushes on the surface of the brush board can brush the glue into the gaps on the side of the board, improving the glue application quality.

[0026] S4: When the second coating roller rotates, the drive disk rotates through the gear. The drive disk drives the first slider to move back and forth through the eccentrically mounted drive shaft and connecting rod, thereby making the first coating roller move. Its rapid movement allows the glue to enter the gap better.

[0027] S5: When the first slider moves, the second slider is also driven to move through the connecting frame. The second slider drives the second mounting frame and the brush plate to move. When the second mounting frame moves, it contacts the arc-shaped protrusion and forms a lateral reciprocating movement with the cooperation of the tension spring. This allows the brush on the surface of the brush plate to fully enter the gaps in the board, avoiding the formation of air bubbles in the gaps that would cause insufficient glue penetration.

[0028] The embodiments of the present invention have the following beneficial effects:

[0029] In this invention, the first driving unit and the first glue-applying roller work together. The first driving unit drives the driving disk to rotate by means of gear transmission, and pulls the first slider to move back and forth via the connecting rod. This causes the first glue-applying roller to move up and down with the slider, so that the glue can be pre-applied to the surface of the board and help the glue to deeply penetrate the side of the board, laying a solid foundation for subsequent glue application.

[0030] In this invention, through the cooperation of the second driving part and the brush plate, when the first slider moves, the second slider moves synchronously through the connecting frame. With the help of the arc-shaped protrusion and the tension spring, the brush plate swings laterally during linear movement. The brush on the brush plate can fully extend into the gap of the board and brush the glue into the gap, effectively avoiding the formation of air bubbles in the gap and ensuring that the glue is fully soaked.

[0031] In this invention, a scraper is used in conjunction with a second coating roller. The scraper is fixed to the top of the glue tank and closely adheres to the surface of the second coating roller. When the second coating roller is dipped in glue and rotates, the scraper can precisely scrape off excess glue from its surface, ensuring a uniform glue layer thickness on the roller surface. This prevents problems such as excessive glue or uneven coating in subsequent applications, thus improving the coating quality.

[0032] In this invention, the conveying mechanism and the pressing mechanism work together. The drive roller of the conveying mechanism provides the conveying power, while the cylinder of the pressing mechanism pushes the second pressure roller to press the sheet material. The combination of these two mechanisms keeps the sheet material stable during conveying and gluing, preventing deviation or shaking, ensuring accurate gluing position, and simultaneously achieving automatic sheet material conveying, reducing manual intervention and improving overall work efficiency.

[0033] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0044] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0045] In one embodiment, please refer to Figures 1-7As shown, this embodiment provides an automatic glue application assembly for composite skin panels, including: a glue tank 8 set at the bottom of the base frame 1, a heating wire installed at the bottom of the glue tank 8 for heating the glue (not shown in the attached figure), a second glue application roller 10 rotatably connected to the surface of the base frame 1, the middle of the second glue application roller 10 being located inside the glue tank 8 and the bottom contacting the glue, slide rails provided on both sides of the glue tank 8, and first sliders 17 slidably connected in the slide rails, a first glue application roller 18 rotatably connected between the two first sliders 17, the first glue application roller 18 and the second glue application roller 10 having the same height and size, the first glue application roller 18 pre-applies glue to the panel in one pass, so that the glue can better enter the gaps on the side of the panel, while the second glue application roller 10 applies glue to the panel a second time, so that the glue on the side of the panel is applied more fully, improving the edge sealing quality;

[0046] The top of the glue box 8 is fixedly connected to two symmetrically arranged rails 24. Each rail 24 is slidably connected to a second slider 25. A second mounting bracket 26 is slidably connected between the second sliders 25. A brush plate 27 is fixedly connected to the top of the second mounting bracket 26. The brush plate 27 is located between the first glue roller 18 and the second glue roller 10. The surface of the brush plate 27 is made of hard bristles and contacts the side of the board, which allows the glue to better enter the gaps on the side of the board.

[0047] A first motor 11 is fixedly connected to one side of the base frame 1. One end of the output shaft of the first motor 11 is fixed to the second glue-applying roller 10. The first motor 11 is used to drive the second glue-applying roller 10 to rotate stably and increase the glue-applying uniformity.

[0048] Two first drive units are respectively disposed on one side of the two first sliders 17 for driving the first glue-applying roller 18 to move and pre-apply glue to the board.

[0049] The second drive unit is located on both sides of the brush plate 27 and is used to drive the brush plate 27 to move and introduce adhesive into the gap of the board.

[0050] In this invention, the first driving unit includes a fixed shaft 19, which is rotatably connected to one side of the glue tank 8. Gears 20 are fixedly connected to both the circumference of the fixed shaft 19 and the circumference of the second glue-applying roller 10, and the two gears 20 mesh. A driving disk 21 is fixedly connected to one end of the fixed shaft 19. A driving shaft 22 is eccentrically fixed to one side of the driving disk 21. A connecting rod 23 is rotatably connected between the driving shaft 22 and the first slider 17 on the same side. When the second glue-applying roller 10 rotates, it drives the driving disk 21 to rotate through the gears 20. The driving disk 21 drives the first slider 17 to reciprocate through the eccentrically mounted driving shaft 22 and the connecting rod 23, thereby making the first glue-applying roller 18 move. Its rapid movement allows the glue to better enter the gap.

[0051] In particular, the second drive unit includes a connecting frame 35, which is fixed to one side of the second slider 25 and the other end is fixed to the first slider 17 on the same side. When the first slider 17 moves, the connecting frame 35 also drives the second slider 25 to move. The second slider 25 drives the second mounting frame 26 and the brush plate 27 to move. The movement of the bristles on the brush plate 27 allows the glue to enter the gap.

[0052] In another embodiment: refer to Appendix Figures 1-7 The automatic gluing assembly for composite skin panels has two baffles 28 fixedly connected to the surface of the glue box 8. One side of one baffle 28 is fixedly connected to multiple parallel arc-shaped protrusions 29. One end of the second mounting bracket 26 abuts against the protrusions 29, and the other end of the second mounting bracket 26 slides through the other baffle 28 and is fixedly installed with a tension spring 30 between them. When the second mounting bracket 26 moves, it contacts the arc-shaped protrusions 29 and forms a lateral reciprocating movement with the cooperation of the tension spring 30. This allows the brush on the surface of the brush plate 27 to fully enter the gaps in the panels, avoiding air bubbles in the gaps that would cause insufficient glue penetration.

[0053] In this invention, a scraper 101 is bolted to the top of the glue box 8. The scraper 101 is located on one side of the second glue roller 10 and is used to remove excess glue from the surface of the second glue roller 10. The scraper 101 is used to smooth the glue adhering to the surface of the second glue roller 10, thereby maintaining the uniformity and effect of glue application.

[0054] Specifically, a third mounting bracket 12 is fixedly connected to one side of the base frame 1, a feeding roller 13 is rotatably connected to one side of the third mounting bracket 12, a second motor 14 is fixedly connected to one side of the third mounting bracket 12, one end of the output shaft of the second motor 14 is fixed to the feeding roller 13, a first mounting bracket 15 is fixedly connected to the bottom of the base frame 1, a first pressure roller 16 is fixed to one side of the first mounting bracket 15 by bolts, the first pressure roller 16 is located on one side of the feeding roller 13 and is used to convey the edge sealing tape, the edge sealing tape roll is set at one end of the base frame 1, the edge sealing tape passes through the bottom of the base frame 1 and is then fed between the feeding roller 13 and the first pressure roller 16, by starting the second motor 14, the feeding roller 13 is rotated, and cooperates with the first pressure roller 16, so that the edge sealing tape is conveyed.

[0055] The present invention also proposes an edge banding device, including an automatic glue application assembly for composite skin panels, and further including multiple support rollers 36 and multiple limiting rollers 9. The multiple support rollers 36 rotate on the top of the base frame 1 to support the panels, and the multiple limiting rollers 9 rotate on one side of the first side frame 2 to limit the position of the panels. The support rollers 36 and limiting rollers 9 facilitate the movement of the panels.

[0056] The conveying mechanism is installed on the surface of the base frame 1 for conveying the sheet metal;

[0057] The pressing mechanism is located on one side of the first side frame 2 and is used to press the sheet metal.

[0058] It should be noted that the conveying mechanism includes a second side frame 7 fixed to the top of the base frame 1. A sliding frame 37 is slidably connected to one side of the second side frame 7. Multiple mounting shafts 31 are rotatably connected to the top of the sliding frame 37. A drive roller 32 is fixedly connected to the top of each mounting shaft 31. A through screw 34 is threaded to one side of the second side frame 7. The other end of the screw 34 is rotatably connected to the sliding frame 37. Adjacent mounting shafts 31 are connected by synchronous pulleys and synchronous belts. A third motor 33 is fixedly connected to the bottom of the sliding frame 37. One end of the output shaft of the third motor 33 is fixed to one of the mounting shafts 31. By rotating the screw 34, the sliding frame 37 is pushed to move, thereby causing the drive roller 32 to come into contact with the plate. The third motor 33 is started, and the friction force is used to drive the drive roller 32 to move the plate.

[0059] In particular, the pressing mechanism includes a side plate 3 fixed to one side of the first side frame 2, a pressure frame 5 slidably connected to the bottom of the side plate 3, a plurality of second pressure rollers 6 rotatably connected to the bottom of the pressure frame 5, and a cylinder 4 fixedly connected to the top of the side plate 3. One end of the piston rod of the cylinder 4 is fixed to the pressure frame 5. The cylinder 4 pushes the second pressure rollers 6 downward to press the board, which facilitates the movement of the board and can adjust the pressure between the edge banding and the board, so that the edge banding and the board can adhere together.

[0060] This invention also proposes an edge-sealing method for edge-sealing equipment, comprising the following steps:

[0061] S1: The edge sealing tape passes through the bottom of the base frame 1 and is then fed between the feeding roller 13 and the first pressure roller 16. By starting the second motor 14, the feeding roller 13 is rotated and cooperates with the first pressure roller 16 to convey the edge sealing tape.

[0062] S2: The plate is placed on the support roller 36. When it enters the side of the drive roller 32, the sliding frame 37 is moved by rotating the screw 34, so that the drive roller 32 comes into contact with the plate. At the same time, the cylinder 4 pushes the second pressure roller 6 to move downward, so that it presses the plate. The third motor 33 is started, and the friction force is used to make the drive roller 32 move the plate.

[0063] S3: When feeding, start the first motor 11, which drives the second glue-applying roller 10 to rotate, thereby applying the glue in the glue tank 8 to one side of the board edge. At the same time, the board comes into contact with the first glue-applying roller 18, and the friction causes it to rotate, thereby driving the glue to pre-contact the board and the glue, so that the glue can better penetrate into the side of the board. At the same time, when the board passes through the brush plate 27, the brush on the surface of the brush plate 27 can brush the glue into the gaps on the side of the board, improving the glue application quality.

[0064] S4: When the second glue-applying roller 10 rotates, the gear 20 drives the drive disk 21 to rotate. The drive disk 21 drives the first slider 17 to move back and forth through the eccentrically mounted drive shaft 22 and connecting rod 23, thereby making the first glue-applying roller 18 move. Its rapid movement allows the glue to better enter the gap.

[0065] S5: When the first slider 17 moves, the second slider 25 is also moved by the connecting frame 35. The second slider 25 moves the second mounting frame 26 and the brush plate 27. When the second mounting frame 26 moves, it contacts the arc-shaped protrusion 29 and forms a lateral reciprocating movement with the cooperation of the tension spring 30. This allows the brush on the surface of the brush plate 27 to fully enter the gaps in the board material, avoiding air bubbles in the gaps that would cause insufficient glue penetration.
