Description

Technical Field

[0001] This application relates to the field of laminating machine technology, and in particular to a double-sided laminating device and pressing assembly for furniture panels. Background Technology

[0002] Furniture board processing requires double-sided lamination of its surface. A laminating machine is a device used to cover various boards with a film to prevent wear. A laminating machine generally includes a work plate, rotating pressure rollers and film placement rollers above the work plate. The boards are driven by the pressure rollers, and the film is adhered to the boards by the pressure rollers. After lamination and other operations, the boards are transported to a designated location through a conveyor system.

[0003] The existing technology still has the following problems:

[0004] 1. The feeding components of the existing laminating equipment are not suitable for different types of boards. When feeding boards of different specifications, manual feeding is often required, which wastes the time and energy of the staff. In addition, the outer surface of the board cannot be cleaned before the film is applied, which makes the film easy to wrinkle after application, affecting work efficiency and film application quality.

[0005] 2. Existing laminating equipment cannot correct the position of the board when applying film, resulting in the film and board not aligning at the corners during application. This affects the appearance, requires cutting off excess material, wastes raw materials, and may even result in some boards not being covered with film, affecting the normal use of the board.

[0006] 3. The existing laminating equipment's laminating assembly can only laminate boards of fixed specifications. When the specifications of the boards change, the spacing between the pressure rollers of the laminating assembly needs to be readjusted, which wastes time. If the spacing is too small, the boards cannot pass through the pressure rollers, and if the spacing is too large, the air bubbles between the boards and the film cannot be removed. Summary of the Invention

[0018] The technical solution provided in this application has at least the following technical effects or advantages:

[0019] 1. Due to the feeding component, the problem of existing laminating devices' feeding components being unsuitable for different types of boards is effectively solved. When feeding boards of different specifications, manual feeding is often required, wasting the time and effort of workers. Furthermore, the outer surface of the board cannot be cleaned before laminating, resulting in wrinkles after lamination, affecting work efficiency and lamination quality. This invention, through the feeding component, can feed boards of different specifications and clean the outer surface of the board while discharging it, keeping the outer surface of the board clean and avoiding air bubbles or wrinkles caused by dust during lamination.

[0020] 2. Due to the adoption of the correction component, the problem of existing laminating devices being unable to correct the position of the board during the lamination process is effectively solved. This results in the film and board being misaligned at the corners, affecting the appearance and requiring the cutting off of excess material, wasting raw materials. In some cases, the film may not even be applied to some boards, affecting their normal use. The present invention can straighten the position of the board during transportation through the correction component, making it easier to accurately align the film during lamination and avoiding waste of film material.

[0021] 3. By employing a film pressing assembly, this invention effectively solves the problem that existing laminating devices can only press films on sheets of fixed specifications. When the sheet specifications change, the spacing between the pressure rollers of the film pressing assembly needs to be readjusted, which wastes time. Furthermore, if the spacing is too small, the sheet cannot pass through the pressure rollers, and if the spacing is too large, air bubbles between the sheet and the film cannot be removed. This invention, through its film pressing assembly, can press films and sheets of different thicknesses together. Moreover, when pressing sheets of different widths, the film pressing assembly has a certain degree of flexibility, ensuring that air bubbles between the sheet and the film can be removed, thus avoiding wrinkles.

[0038] Since the feeding component cannot be used for different types of boards, this invention can feed boards of different specifications through the feeding component; since the laminating device cannot correct the position of the board when applying film, this invention can straighten the position of the board during transportation through the correction component; since the laminating device's pressing component can only press the film onto boards of fixed specifications, this invention can press the film and film of different thicknesses together through the pressing component.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Example 1: Please refer to Figure 1 and Figure 2As shown, a double-sided laminating device for furniture boards includes a laminating machine body 1. A feeding component 2 is fixedly installed at one end of the laminating machine body 1. A second motor 3 is provided on one side of the laminating machine body 1. A feeding wheel 4 is rotatably connected to the inner cavity of the laminating machine body 1. A straightening component 5 is provided in the middle part of the laminating machine body 1. A film roll 7 is rotatably connected to the end of the laminating machine body 1 away from the feeding component 2. There are two film rolls 7 to facilitate double-sided lamination, and they are located on both sides of the plane where the feeding wheel 4 is located. The feeding component 2 is used for feeding boards and can transport boards of different specifications. During transportation, the outer surface of the boards is cleaned. The second motor 3 drives the feeding wheel 4 to rotate and transport the boards. The straightening component 5 can correct the position of the boards. The film roll 7 is used for laminating the boards.

[0041] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the feeding assembly 2 includes a collection bin 21. A first motor 22 is installed at the bottom of the collection bin 21. Two rotating rods 23 are rotatably connected to the bottom of the collection bin 21, and the output end of the first motor 22 is sleeved with one of the rotating rods 23. A conveyor belt 24 is sleeved on the outer surface of the rotating rod 23, and a pushing mechanism 25 is fixedly installed on the outer surface of the conveyor belt 24. An adjusting mechanism 26 is slidably connected to the side of the collection bin 21 near the feeding wheel 4. A second insertion hole 27 is opened on the inner wall of the collection bin 21, and the second insertion hole 27 is located on both sides of the adjusting mechanism 26. A first connecting block 28 is fixedly installed at the bottom of the adjusting mechanism 26. A cleaning mechanism 29 is provided in the inner cavity of the laminating machine body 1. A connecting groove is opened at the bottom of the collection bin 21. When the conveyor belt 24 drives the pushing mechanism 25 to move, it passes through the connecting groove. The top of the structure 25 protrudes from the bottom inner wall of the collection chamber 21. There are two cleaning mechanisms 29, with the upper cleaning mechanism 29 fixedly connected to the first connecting block 28 and the lower cleaning mechanism 29 fixed to the inner wall of the laminating machine body 1. When feeding, the operation of the first motor 22 drives the rotating rod 23 to rotate, and the rotation of the rotating rod 23 drives the conveyor belt 24 to rotate. The rotation of the conveyor belt 24 drives the pushing mechanism 25 to move in the connecting groove of the collection chamber 21. The collection chamber 21 holds multiple boards of the same specifications to be laminated. The movement of the pushing mechanism 25 pushes the bottom board out of the gap between the collection chamber 21 and the adjusting mechanism 26. The cleaning mechanism 29 can clean the outer surface of the transported board. The adjustment of the pushing mechanism 25, the adjusting mechanism 26 and the cleaning mechanism 29 can be used for transporting and cleaning different specifications.

[0042] Please see Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the feeding mechanism 25 includes an adjusting seat 251, which is fixedly connected to the conveyor belt 24. A telescopic block 252 is slidably connected to the inner cavity of the adjusting seat 251. A first insertion hole 253 is provided on the outer surface of the telescopic block 252. A first fixing block 254 is fixedly installed on the outer surface of the adjusting seat 251. A first insert rod 255 is inserted into the inner cavity of the first fixing block 254. The first insert rod 255 passes through the adjusting seat 251 and the first insertion hole 253 and is inserted into the first insertion hole 253. A fixing ring 256 is fixedly installed on the outer surface of the first insert rod 255. A first spring 257 is sleeved on the outer surface of the first insert rod 255. The first spring 257 is located in the fixed position. Between the fixed ring 256 and the first fixed block 254, the adjusting mechanism 26 includes an adjusting plate 261. A gear 262 is rotatably connected to the upper inner cavity of the adjusting plate 261. A hand lever 263 is fixedly installed on the outer surface of the gear 262. The hand lever 263 and the adjusting plate 261 are rotatably connected. A rack 264 is slidably connected to the upper and lower ends of the gear 262. The gear 262 and the rack 264 mesh, and the rack 264 is slidably connected to the inner wall of the adjusting plate 261. A second insert rod 265 is fixedly installed on the outer surface of the rack 264. The second insert rod 265 passes through the adjusting plate 261 and is inserted into the second insertion hole 27, which can be adjusted according to the thickness of the plate. The height of the pushing mechanism 25 is adjusted by pulling the first insert rod 255 to disengage it from the first insertion hole 253. At this time, the telescopic block 252 is moved within the adjusting seat 251. Once in the appropriate position, the first insert rod 255 is released, and the elastic force of the first spring 257 presses against the fixing ring 256, causing the first insert rod 255 to re-engage with the first insertion hole 253. The top of the telescopic block 252 remains in the middle of the lowest layer of material, thus moving the lowest layer of material in the collection bin 21. Simultaneously, the position of the adjusting mechanism 26 is adjusted to maintain the clearance between the adjusting mechanism 26 and the outlet direction of the collection bin 21. The system allows one sheet of material to pass through, but not two sheets at the same time. By rotating the hand lever 263, the gear 262 rotates, which in turn moves the rack 264. The movement of the rack 264 causes the second insert 265 to disengage from the second insertion hole 27. At this time, the sliding adjustment plate 261 keeps the bottom of the adjustment plate 261 and the collection bin 21 in a position where one sheet of material can pass through. When the material is in the appropriate position, the hand lever 263 is rotated again to engage the second insert 265 with the second insertion hole 27, fixing the adjustment plate 261 to the inner wall of the collection bin 21. With the adjustment of the pushing mechanism 25, sheets of different specifications can be transported.

[0043] Please see Figure 7 , Figure 8 and Figure 9As shown, the cleaning mechanism 29 includes a cleaning wheel 291. First connecting rods 292 are fixedly mounted on both sides of the cleaning wheel 291. A cleaning box 293 is located on the side of the first connecting rods 292 away from the adjusting mechanism 26. Second connecting rods 294 are fixedly mounted on both ends of the cleaning box 293. A scraper 295 is located on the side of the cleaning box 293 near the cleaning wheel 291. The scraper 295 and the cleaning wheel 291 are in close contact, with the upper scraper 295 located at the upper end of the cleaning box 293 and the lower scraper 295 located at the lower end of the cleaning box 293. Thus, the lower scraper 295 is driven by the second motor 3. When the first connecting rod 292 rotates, the scrapers 295 at both ends scrape against it. A dust collection box 296 is slidably connected to the bottom inner cavity of the cleaning box 293. The first connecting block 28 is fixedly sleeved with the upper first connecting rod 292. When the first connecting block 28 moves, it drives the upper cleaning mechanism 29 to move. The inner wall of the laminating machine body 1 is fixedly connected to the lower second connecting rod 294. The lower first connecting rod 292 is sleeved with the output end of the second motor 3, and a belt is sleeved on the lower first connecting rod 292. The other end of the belt is sleeved with the feeding wheel 4. When the first connecting rod 292 rotates, it drives the feeding wheel 4 to rotate. When the board passes through the cleaning mechanism 29, the cleaning wheel 291 can clean the upper and lower outer surfaces of the board. The second motor 3 drives the lower first connecting rod 292 to rotate, causing the cleaning wheel 291 to rotate. During the movement of the board, the upper first connecting rod 292 rotates, thus the first connecting rod 292 cleans the outer surface of the board. During the rotation of the first connecting rod 292, the scraper 295 on the cleaning box 293 scrapes the stains generated by the cleaning wheel 291, causing the stains to fall into the dust collection box 296 of the cleaning box 293. The stains in the dust collection box 296 are cleaned regularly. When the position of the adjusting plate 261 is adjusted, the movement of the adjusting plate 261 drives the first connecting block 28 to move. The movement of the first connecting block 28 drives the upper first connecting rod 292 to move. Thus, the spacing between the cleaning wheels 291 can be adjusted at the same time as the adjusting mechanism 26 is adjusted, so that the upper and lower surfaces of the board can be cleaned when the board passes through the cleaning wheel 291.

[0044] Please see Figure 10 and Figure 11As shown, the correction assembly 5 includes a correction frame 51. Second fixing blocks 52 are slidably connected to both ends of the correction frame 51. The second fixing blocks 52 are fixedly connected to the outer surfaces of both sides of the laminating machine body 1. Second springs 53 are fixedly connected to both ends of the correction frame 51. The end of the second spring 53 away from the correction frame 51 is fixedly connected to the second fixing block 52. A first sliding groove 54 is provided in the middle of the correction frame 51. Limiting holes 55 are provided on both sides of the first sliding groove 54. A correction mechanism 5 is slidably connected to the inner cavity of the first sliding groove 54. 6. There are two straightening mechanisms 56, located on the upper surfaces of both sides of the laminating machine body 1. Each straightening mechanism 56 includes a first slider 561. A second connecting block 562 is fixedly installed at the bottom end of the first slider 561. Limiting rods 563 are fixedly installed on both sides of the lower surface of the first slider 561, and the limiting rods 563 are located on both sides of the second connecting block 562. An inclined frame 564 is fixedly installed at the bottom end of the second connecting block 562. The inclined frame 564 is inclined on the side closer to the middle part of the laminating machine body 1 and towards the film roll 7. The plate gradually widens, ensuring that the plate remains in the middle of the laminating machine body 1 after the guiding process. The inner cavity of the tilting frame 564 is rotatably connected to the guide wheel 565. When the plate is transported on the feeding wheel 4, the position of the plate can be corrected by the correction component 5. By moving the position of the correction mechanism 56 on the correction frame 51, the distance between the correction mechanisms 56 can be adjusted to ensure that the end of the correction mechanism 56 can pass through the plate. When the plate contacts the guide wheel 565, the plate is guided to the other end. With the movement of the correction frame 51 on the second fixed block 52 and the elastic force of the second spring 53, the position of the correction frame 51 can be quickly restored to the initial position. This allows the plate to move in the middle of the laminating machine body 1. By sliding the second connecting block 562 in the first slide groove 54 and then inserting the limiting rod 563 and the limiting hole 55, the correction mechanism 56 is fixed as a whole, which is convenient for adapting to different specifications of plates. The rotation of the guide wheel 565 moves the plate on the feeding wheel 4, ensuring that the position of the plate and the film are aligned during lamination.

[0045] Example 2: Please refer to Figure 12 , Figure 13 , Figure 14 and Figure 15As shown, the machine includes a film pressing assembly 6, which is installed on the inner wall of the laminating machine body 1 and near one end of the film roll 7. The film pressing assembly 6 includes a fixing frame 61, which is located on the inner wall of the laminating machine body 1 and near one end of the film roll 7. Limiting sleeves 62 are fixedly installed on the inner walls of both the upper and lower ends of the fixing frame 61. A movable frame 63 is slidably connected to the inner cavity of the limiting sleeve 62. A pressure roller 64 is rotatably connected to the inner cavity of the movable frame 63. There are two limiting sleeves 62, two movable frames 63, and two pressure rollers 64. There is a slight gap between the pressure rollers 64. A flexible mechanism 65 is fixedly connected to the end of the movable frame 63 away from the pressure roller 64. The flexible mechanism 65 includes a fixed seat 651, and a sliding mechanism 65 is slidably connected to the inner cavity of the fixed seat 651. A third connecting rod 653 is fixedly installed on the outer surface of the slide plate 652. Pressure rods 654 are rotatably connected to both ends of the slide plate 652. Second sliding grooves 655 are provided at both ends of the fixed seat 651. Second sliders 656 are slidably connected to the inner cavity of the fixed seat 651. Sliding rods 657 are fixedly installed at both ends of the second sliders 656. A third spring 658 is fixedly connected to the inner wall of the fixed seat 651. Three second sliders 656 are provided at both ends of the fixed seat 651. The outer surface of the second sliders 656 is inclined, and the inclined surface is in close contact with the pressure rods 654. The end of the third spring 658 away from the fixed seat 651 is fixedly connected to the second sliders 656. The sliding rods 657 and the second sliding grooves 655 slide... The dynamic connection involves the pressure rollers 64 pressing the sheet material after it has been laminated. The pressure rollers 64 adhere the sheet material and film together, eliminating wrinkles and air bubbles. Simultaneously, the pressure rollers 64 maintain a degree of flexibility during the lamination process. When the width gap between the sheets is greater than the distance between the pressure rollers 64, the rollers 64 press outwards. This causes the pressure rollers 64 to move the moving frame 63, pressing the third connecting rod 653. The third connecting rod 653 then presses the sliding plate 652, which in turn moves the pressure rod 654 to press the second slider 656. Meanwhile, the guide wheel 565 presses the third spring 658, thus maintaining a constant degree of flexibility. However, if the width gap between the sheets is too large, the distance between the pressure rollers 64 will become too wide. When the gap between the plates is too small, the second slider 656 slides inside the cavity of the fixed seat 651, allowing the second slider 656 to be housed inside the fixed seat 651. At this time, the second slide groove 655 slides onto the next second slider 656. In this way, under the pressure of the plate, the pressure roller 64 can regain the appropriate flexible pressing force. When the gap between the plates is too small, the slide bar 657 can be slid to return the slide plate 652 to the outermost position. When applying film to a batch of plates, the ones with smaller widths are applied first. In this way, the flexible mechanism 65 can automatically correct the flexible force to ensure that the film application force is appropriate. The flexible force can adapt to plates with various widths and gaps, and the flexible force changes with the increase of the width of the plate to ensure that there are no wrinkles in the plate and the film.

[0046] In summary, during feeding, the first motor 22 drives the pushing mechanism 25 to move in the connecting groove of the collection bin 21. The movement of the pushing mechanism 25 pushes the bottom layer of the board material out of the gap between the collection bin 21 and the adjusting mechanism 26. The cleaning mechanism 29 can clean the outer surface of the transported board material. Pulling the first insertion rod 255 disengages it from the first insertion hole 253. At this time, the telescopic block 252 moves in the inner cavity of the adjusting seat 251. When it reaches the appropriate position, the first insertion rod 255 is released. The elastic force of the first spring 257 presses the fixing ring 256, causing the first insertion rod 255 to re-engage with the first insertion hole 253. 53. With the top of the telescopic block 252 in the middle of the lowest layer of material, the bottom layer of material in the collection bin 21 can be moved. At the same time, the hand lever 263 is turned to disengage the second insert rod 265 and the second insert hole 27. At this time, the sliding adjustment plate 261 keeps the bottom of the adjustment plate 261 and the collection bin 21 in a way that allows a piece of material to pass through. With the adjustment of the pushing mechanism 25, materials of different specifications can be transported. When the material passes through the cleaning mechanism 29, the cleaning wheel 291 can clean the upper and lower outer surfaces of the material. During the rotation of the first connecting rod 292, the scraper 295 on the cleaning box 293 cleans the surface of the material. The cleaning wheel 291 scrapes against the stains generated during cleaning, causing them to fall into the dust collection box 296 of the cleaning box 293. The dust collection box 296 is periodically cleaned. When the board is transported on the feeding wheel 4, the position of the board can be corrected by the straightening assembly 5. By moving the position of the straightening mechanism 56 on the straightening frame 51, the distance between the straightening mechanisms 56 is adjusted to ensure that the end of the straightening mechanism 56 can pass through the board. When the board contacts the guide wheel 565, it is guided to the other end. Combined with the movement of the straightening frame 51 on the second fixed block 52 and the elastic force of the second spring 53, the position of the straightening frame 51 can be quickly restored. The initial position allows the sheet material to move in the middle of the laminating machine body 1, ensuring that the sheet material and film are aligned during lamination. After lamination, the sheet material passes through the pressure roller 64, where the pressure roller 64 presses against the sheet material and film to prevent wrinkles and remove air bubbles. The pressure roller 64 also provides a degree of flexibility during lamination. The width of the sheet material is greater than the distance between the pressure rollers 64, causing them to press outwards. At this time, the guide wheel 565 presses against the third spring 658, maintaining a certain degree of flexibility so that the pressing force varies with the thickness of the sheet material.
