Description

Technical Field

[0001] This utility model relates to the field of flat lamination production line technology, and in particular to a PUR hot glue double-sided roller coating flat lamination production line. Background Technology

[0002] PUR (Polyurethane Reactive) is a moisture-curing reactive polyurethane hot melt adhesive. Its main component is isocyanate-terminated polyurethane prepolymer. PUR offers adjustable adhesion and toughness (elasticity), and boasts excellent bond strength, temperature resistance, chemical resistance, and aging resistance. In recent years, it has become one of the most important adhesive products in the industry. It is now widely used in packaging, wood processing, automotive, textile, electromechanical, aerospace, and other sectors of the national economy.

[0003] In some applications, boards need to be laminated on both sides, such as those used for ventilation ducts. However, existing PUR hot glue lamination production lines apply glue to one side first and then apply it to the other side, resulting in low production efficiency. Furthermore, two sets of glue application and lamination equipment are required, making the entire PUR lamination production line structure bulky and requiring a large production line layout space.

[0004] The technical problem to be solved by this utility model is: how to solve the problems of low working efficiency and large footprint of existing PUR hot glue flat lamination production lines. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a PUR hot glue double-sided roller coating flat lamination production line, which can perform double-sided flat lamination, significantly improves the production efficiency compared with the traditional single-sided glue coating flat lamination, and the overall structure is also more compact.

[0006] The technical solution adopted by this utility model is: a PUR hot glue double-sided roller coating planar bonding production line, including a feeding machine and a feeding machine, and a double-sided glue coating machine and a re-pressing bonding machine are arranged sequentially between the feeding machine and the feeding machine;

[0007] The double-sided glue applicator includes a glue applicator frame, an upper glue applicator roller, an upper glue control roller, a lower glue applicator roller, and a lower glue control roller, which are respectively installed on the glue applicator frame. The upper glue applicator roller and the lower glue applicator roller are arranged at intervals relative to each other in the vertical direction. The upper glue control roller is arranged at intervals on one side of the upper glue applicator roller, and the lower glue control roller is arranged at intervals on one side of the lower glue applicator roller.

[0008] The repressing and laminating machine includes a repressing frame, an upper pressing frame, and a lower pressing frame. The upper pressing frame and the lower pressing frame are arranged at intervals relative to each other in the vertical direction. Several upper pressing rollers are arranged at intervals along the conveying direction on the upper pressing frame, and several lower pressing rollers corresponding to the upper pressing rollers are arranged at intervals along the conveying direction on the lower pressing frame. The repressing frame is also equipped with a pressing drive component for driving the upper pressing frame and / or the lower pressing frame to rise and fall.

[0009] The PUR hot glue double-sided roller coating planar lamination production line of this application can apply PUR hot glue to the upper and lower surfaces of the board by setting up a double-sided glue applicator. After the glue is applied, the board and the roll material are simultaneously bonded to the upper and lower surfaces of the board by a re-pressing lamination. Several upper and lower pressure rollers arranged at intervals along the conveying direction on the re-pressing lamination machine can achieve long-term pressure application and pressure holding, so that the roll material and glue can be fully bonded to the board surface, reducing defects such as bulging and delamination. In addition, this production line can achieve simultaneous double-sided lamination by combining the double-sided glue applicator and the re-pressing lamination machine, which has higher working efficiency and makes the overall structure of the production line more compact.

[0010] In some embodiments, the double-sided adhesive applicator further includes a first adhesive applicator power component, a second adhesive applicator power component, a first adhesive control power component, a second adhesive control power component, and a gap adjustment power component, all respectively mounted on the applicator frame. The first adhesive applicator power component drives the upper adhesive roller to rotate, the second adhesive applicator power component drives the lower adhesive roller to rotate, the first adhesive control power component is drivenly connected to the upper adhesive control roller and is used to drive the upper adhesive control roller closer to or away from the upper adhesive roller, the second adhesive control power component is drivenly connected to the lower adhesive control roller and is used to drive the lower adhesive control roller closer to or away from the lower adhesive roller, and the gap adjustment power component is used to adjust the distance between the upper adhesive roller and the lower adhesive roller.

[0011] By adopting the above technical solution, applying glue by rolling can make the glue application more uniform. By setting up a glue control power component, the thickness of the glue on the glue roller can be adjusted according to the needs, making the adjustment more convenient. The gap adjustment power component can adjust the gap between the upper and lower glue rollers according to the thickness of the board, ensuring the glue application effect.

[0012] In some embodiments, a first feeding power component is provided on the upper pressure frame, and the first feeding power component is connected to each upper pressure roller to drive each upper pressure roller to rotate; a second feeding power component is provided on the lower pressure frame, and the second feeding power component is connected to each lower pressure roller to drive each lower pressure roller to rotate.

[0013] By adopting the above technical solution, the cooperation between the first and second feeding power components enables the sheet material to be pressed and bonded during its movement, thereby improving the bonding efficiency and the flow efficiency of the production line.

[0014] In some embodiments, the double-sided coating machine further includes a second unwinding position, a first protective film roller, and a second protective film roller disposed on the repress frame. The second unwinding position is disposed at the top of the repress frame, and the first and second protective film rollers are disposed at the end of the repress frame away from the double-sided coating machine. The first protective film roller is located above the upper pressure roller, and the second protective film roller is located below the lower pressure roller.

[0015] By adopting the above technical solution, space can be saved and the unwinding path of the roll material can be shortened by setting a second unwinding position for placing the roll material on the repressing frame. Furthermore, by setting a first protective film roller and a second protective film roller at the output end of the repressing frame, a protective film can be wrapped around the upper and lower surfaces of the board after it is laminated, so as to protect the laminated board material.

[0016] In some embodiments, a cutting and grooving machine is also included, which is disposed between the laminating machine and the blanking machine. The cutting and grooving machine includes a fixed frame, a movable frame that slides with the fixed frame, a following power component that drives the movable frame, and a cutting module and a grooving module respectively installed on the movable frame. The following power component drives the movable frame to move with the product during cutting and grooving and drives the movable frame to return to the origin after cutting and grooving is completed. The cutting module is used to cut the board and / or protective film, and the grooving module is used to groove the surface of the board.

[0017] By adopting the above technical solution and setting up a board cutting and grooving machine, the board can be processed synchronously during its movement. After processing is completed, the machine can quickly move back to the original point to process the next board. This can improve the efficiency of board processing, reduce downtime, and thus increase the turnover speed of the production line.

[0018] In some embodiments, the cutting module includes a cutting beam, a cutting head, and a first pressure plate. The cutting beam is fixedly mounted on one end of the movable frame near the re-pressing and bonding machine. The cutting head includes a cutting slide that is slidably connected to the cutting beam, a cutting lateral movement force member that drives the cutting slide to slide, and a cutting piece mounted on the cutting slide. The first pressure plate is mounted above the worktable of the movable frame and corresponds to the cutting piece. The first pressure plate is connected to a first pressing force member.

[0019] By adopting the above technical solution, the cutting slide is driven to move along the cutting beam by the cutting plate transverse moving force component, so that the plate can be cut into the required size or the film can be cut according to the needs. The processing efficiency is high and the subsequent processing steps are reduced. During cutting, the first pressing force component drives the first pressing plate to press the plate to prevent the plate from shifting during the cutting process, thereby improving the cutting accuracy.

[0020] In some embodiments, the grooving module includes a grooving crossbeam, a grooving head, and a second pressure plate. The grooving crossbeam is slidably connected to the movable frame. The grooving head includes a grooving slide that is slidably connected to the grooving crossbeam, a grooving lateral movement force component that drives the grooving slide to slide, and a grooving component installed on the grooving slide. The second pressure plate is mounted above the worktable of the movable frame and is connected to the grooving crossbeam. The second pressure plate corresponds to the grooving component. A second pressing force component that drives the second pressure plate to rise and fall is provided on the grooving crossbeam.

[0021] By adopting the above technical solution, the grooving slide and the grooving component are driven to move on the grooving beam by the grooving transverse moving force component. During the movement, the grooving component processes the required groove on the surface of the plate, which has high processing efficiency and reduces the number of subsequent processing steps. The second pressing force component cooperates with the second pressing plate to press the plate during grooving, thereby improving the accuracy of grooving.

[0022] In some embodiments, the plate cutting and grooving machine also includes a material guiding module mounted on a movable frame. The material guiding module includes a flow bar disposed below the worktable of the movable frame and a lifting power component for driving the flow bar to rise and fall. The worktable of the movable frame is provided with an anti-airway groove corresponding to the flow bar.

[0023] By adopting the above technical solution, during feeding or discharging, the lifting power component drives the flow bar to rise, thereby reducing the resistance to the movement of the sheet material. When cutting and grooving are required, the lifting power component drives the flow bar to fall, so that the sheet material fits against the worktable, preventing the sheet material from shifting and improving processing accuracy.

[0024] In some embodiments, a conveying mechanism is also included, which includes a first conveyor table, a second conveyor table, a third conveyor table, and a fourth conveyor table. The first conveyor table, the second conveyor table, and the third conveyor table are sequentially arranged between the feeder and the double-sided adhesive applicator. A cleaning component is provided on the first conveyor table, a first unwinding position is provided at the bottom of the second conveyor table, a heating component is provided on the third conveyor table, and the fourth conveyor table is arranged between the plate cutting and grooving machine and the unloading machine.

[0025] Using the above technical solution, the cleaning component on the first conveyor table can clean the board and remove debris from the surface of the board to ensure the subsequent bonding quality. The first unwinding position at the bottom of the second conveyor table is used to place the roll material to avoid the roll material interfering with the movement of the board. The heating component on the third conveyor table can preheat the board to facilitate the subsequent application of PUR hot glue.

[0026] In some implementations, a flipping machine is also included, which is positioned between the fourth conveyor and the unloading machine.

[0027] Using the above technical solution, the flipping machine can flip the processed boards 180° to facilitate the unloading and stacking of the material by the unloading machine. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Please see Figures 1 to 12 This invention discloses a preferred embodiment of a PUR hot glue double-sided roller coating and flat lamination production line 100. The production line is sequentially arranged along the conveying direction as a feeding machine 10, a double-sided glue applicator 30, a re-pressing and laminating machine 40, a board cutting and grooving machine 50, a board flipping machine 60, and a unloading machine 70. To facilitate smoother board conveying and provide buffering, the production line also includes a conveying mechanism 20. The conveying mechanism 20 includes a first conveying table 21, a second conveying table 22, and a third conveying table 23 positioned between the feeding machine 10 and the double-sided glue applicator 30, and a fourth conveying table 24 positioned between the board flipping machine 60 and the board cutting and grooving machine 50. This production line is capable of double-sided flat lamination, significantly improving production efficiency compared to traditional single-sided glue application and flat lamination, and also features a more compact overall structure.

[0045] like Figure 3 and Figure 4 As shown, the feeding machine 10 includes a crane 11 and a roller frame 12 disposed on one side of the crane 11. The roller frame 12 can be selected as an automatic force roller or a non-powered roller according to the requirements, and no specific limitation is made here. Since this production line mainly produces flat products, the crane 11 preferably uses a suction cup to pick up and place workpieces. In other embodiments, grippers can also be used to pick up and place workpieces. If the product being produced can be attracted by a magnet, a magnetic attraction method can also be used to pick up and place the workpiece.

[0046] Please refer to the following: Figure 3 and Figure 4 The first conveyor 21, the second conveyor 22, and the third conveyor 23 are sequentially arranged between the feeder 10 and the double-sided adhesive applicator 30. The first conveyor 21 is equipped with a cleaning component 211, the second conveyor 22 has a first unwinding position 221 at its bottom, and the third conveyor 23 is equipped with a heating component 231. Specifically, the cleaning component 211 includes a brush roller and an air knife, which remove dust and other impurities from the surface of the board by brushing and blowing. The heating component 231 is a hot air box. The cleaning component 211 on the first conveyor 21 cleans the board, removing impurities from its surface to ensure subsequent bonding quality. The first unwinding position 221 at the bottom of the second conveyor 22 is used to place the roll material to avoid interference with the board's movement. The heating component 231 on the third conveyor 23 preheats the board to facilitate the subsequent application of PUR hot adhesive.

[0047] Preferably, in order to facilitate loading and unloading of the roll material, the second conveyor table 22 is a foldable conveyor table. When loading and unloading the roll material, the second conveyor table 22 can be folded upward to facilitate entry into the first unwinding position 221 for loading and unloading the roll material. During normal operation, the second conveyor table 22 is unfolded to transport the sheet material.

[0048] like Figure 5 and Figure 6 As shown, the double-sided adhesive applicator 30 includes an adhesive applicator frame 31, an upper adhesive applicator roller 32, an upper control adhesive roller 33, a lower adhesive applicator roller 34, and a lower control adhesive roller 35, all mounted on the adhesive applicator frame 31. The upper adhesive applicator roller 32 and the lower adhesive applicator roller 34 are arranged vertically at intervals. The upper control adhesive roller 33 is spaced apart on one side of the upper adhesive applicator roller 32, and the lower control adhesive roller 35 is spaced apart on one side of the lower adhesive applicator roller 34. By using the double-sided adhesive applicator 30, PUR hot adhesive can be applied to the upper and lower surfaces of the board. After adhesive application, the board and the roll material are simultaneously bonded to the upper and lower surfaces of the board through a re-pressing bonding process.

[0049] Furthermore, the double-sided glue applicator 30 also includes a first glue applicator power component 36, a second glue applicator power component 37, a first glue control power component 39, a second glue control power component, and a gap adjustment power component 38, which are respectively installed on the glue applicator frame 31. The first glue applicator power component 36 drives the upper glue applicator roller 32 to rotate, the second glue applicator power component 37 drives the lower glue applicator roller 34 to rotate, the first glue control power component 39 is connected to the upper glue control roller 33 for driving the upper glue control roller 33 closer to or away from the upper glue applicator roller 32, the second glue control power component is connected to the lower glue control roller 35 for driving the lower glue control roller 35 closer to or away from the lower glue applicator roller 34, and the gap adjustment power component 38 is used to adjust the distance between the upper glue applicator roller 32 and the lower glue applicator roller 34. Applying glue by rolling makes the glue application more uniform. The glue control motor can adjust the thickness of the glue on the application roller as needed, making adjustment more convenient. The gap adjustment motor can adjust the gap between the upper application roller 32 and the lower application roller 34 according to the thickness of the board, ensuring the glue application effect.

[0050] Optionally, the first glue application power component 36, the second glue application power component 37, and the gap adjustment power component 38 are all motors. The upper glue application roller 32 and the upper control glue roller 33 are mounted on the first slide block. The first slide block is slidably connected to the glue application frame 31. The gap adjustment power component 38 drives the first slide block to rise and fall relative to the glue application frame 31, thereby realizing the gap adjustment between the upper glue application roller 32 and the lower glue application roller 34.

[0051] Furthermore, an upper adhesive control slide is slidably mounted on the first slide, and the upper adhesive control roller 33 is mounted on the upper adhesive control slide. The first adhesive control power component 39 drives the upper adhesive control slide to move closer to or further away from the upper adhesive coating roller 32, thereby adjusting the thickness of the hot adhesive on the surface of the upper adhesive coating roller 32. In this embodiment, both the first adhesive control power component 39 and the second adhesive control power component are worm gear reducers. The working principles of the lower adhesive coating roller 34 and the lower adhesive control roller 35 are the same as those of the upper adhesive coating roller 32 and the upper adhesive control roller 33, and will not be described again here.

[0052] Preferably, the double-sided glue applicator 30 is equipped with a glue melter, which is connected to a glue box or glue gun.

[0053] like Figures 7 to 9 As shown, the re-pressing and laminating machine 40 includes a re-pressing frame 41, an upper pressing frame 42, and a lower pressing frame 43. The upper pressing frame 42 and the lower pressing frame are arranged vertically at intervals. A plurality of upper pressing rollers 44 are spaced apart on the upper pressing frame 42 along the conveying direction, and a plurality of lower pressing rollers 45 corresponding to the upper pressing rollers 44 are spaced apart on the lower pressing frame 43 along the conveying direction. The re-pressing frame 41 is also equipped with a pressing drive component 46 for driving the upper pressing frame 42 and / or the lower pressing frame 43 to rise and fall. The plurality of upper pressing rollers 44 and lower pressing rollers 45 spaced apart along the conveying direction on the re-pressing and laminating machine 40 can achieve long-term pressure application and holding, allowing the roll material and adhesive to fully adhere to the board surface, reducing defects such as bulging and delamination.

[0054] Furthermore, the upper pressure frame 42 is equipped with a first feeding power component 47, which is connected to each upper pressure roller 44 to drive the upper pressure roller 44 to rotate; the lower pressure frame 43 is equipped with a second feeding power component, which is connected to each lower pressure roller 45 to drive the lower pressure roller 45 to rotate. Through the cooperation of the first feeding power component 47 and the second feeding power component, the sheet material can be pressed and bonded during travel, improving bonding efficiency and increasing the flow efficiency of the production line.

[0055] In this embodiment, both the first feeding power component 47 and the second feeding power component are electric motors. The first feeding power component 47 drives each upper pressure roller 44 to rotate synchronously through a chain and sprocket. Similarly, the second feeding power component drives each lower pressure roller 45 to rotate synchronously through a chain and sprocket.

[0056] Furthermore, the pressing drive 46 is mounted on the upper pressing frame 42, which is slidably connected to the repress frame 41. The pressing drive 46 is a motor, which drives the upper pressing frame 42 to rise and fall through a worm gear reducer.

[0057] Furthermore, the double-sided adhesive applicator 30 also includes a second unwinding position 48, a first protective film roller 49, and a second protective film roller, all disposed on the repress frame 41. The second unwinding position 48 is located at the top of the repress frame 41, while the first and second protective film rollers are located at the end of the repress frame 41 furthest from the double-sided adhesive applicator 30. The first protective film roller 49 is positioned above the upper pressure roller 44, and the second protective film roller is positioned below the lower pressure roller 45. By providing the second unwinding position 48 for placing the roll material on the repress frame 41, space can be saved, and the unwinding path of the roll material can be shortened. The first and second protective film rollers are located at the output end of the repress frame 41, allowing protective films to be wrapped around the upper and lower surfaces of the laminated material after bonding, thus protecting the bonded material.

[0058] like Figure 10 and Figure 11 As shown, the plate cutting and grooving machine 50 includes a fixed frame 51, a movable frame 52 that slides with the fixed frame 51, a following power component 53 that drives the movable frame 52, and a cutting module 54 and a grooving module 55 respectively mounted on the movable frame 52. The following power component 53 drives the movable frame 52 to move with the product during cutting and grooving, and drives the movable frame 52 back to its origin after cutting and grooving is completed. The cutting module 54 is used to cut the plate and / or protective film, and the grooving module 55 is used to groove the surface of the plate. By setting up the plate cutting and grooving machine 50, synchronous following processing can be performed during the plate's movement. After processing is completed, it quickly moves back to its origin to process the next plate, which can improve the efficiency of plate processing, reduce downtime, and thus increase the production line's turnover speed.

[0059] Preferably, the following power component 53 is a servo motor.

[0060] Preferably, in order to improve processing accuracy, sensors are installed at the working origins of the moving frame 52, the cutting module 54, and the grooving module 55. The sensors, in conjunction with the controller, can further improve processing accuracy.

[0061] Specifically, the cutting module 54 includes a cutting beam 541, a cutting head, and a first pressure plate 545. The cutting beam 541 is fixedly installed at one end of the movable frame 52 near the re-pressing and bonding machine 40. The cutting head includes a cutting slide 542 slidably connected to the cutting beam 541, a cutting lateral movement force member 543 for driving the cutting slide 542 to slide, and a cutting piece 544 installed on the cutting slide 542. The first pressure plate 545 is located above the worktable of the movable frame 52, and the first pressure plate 545 corresponds to the cutting piece 544. The first pressure plate 545 is connected to a first pressing power member 546. The cutting slide 542 is driven by the cutting plate lateral movement force component 543 to move along the cutting plate beam 541, so that the plate can be cut into the required size or the film can be cut according to the needs. The processing efficiency is high and the subsequent processing steps are reduced. During cutting, the first pressing force component 546 drives the first pressing plate 545 to press the plate to prevent the plate from shifting during the cutting process and improve the cutting accuracy.

[0062] In this embodiment, the cutting module 54 is equipped with two cutting heads. By using two cutting heads, one can be used for primary processing while the other serves as a backup. Different cutting components 544 can also be installed on the two cutting heads to achieve different cutting functions. For example, a saw blade can be installed as the cutting component 544 on one cutting head, and a cutting cutter can be installed as the cutting component 544 on the other. In other embodiments, cutting tools such as drill bits or milling cutters can also be used as the cutting components 544.

[0063] Optionally, the cutting plate lateral movement force component 543 is a motor, and the first pressing force component 546 is a cylinder.

[0064] Specifically, the grooving module 55 includes a grooving crossbeam 551, a grooving head, and a second pressure plate 555. The grooving crossbeam 551 is slidably connected to the movable frame 52. The grooving head includes a grooving slide 552 slidably connected to the grooving crossbeam 551, a grooving transverse moving force component 553 that drives the grooving slide 552 to slide, and a grooving component 554 installed on the grooving slide 552. The second pressure plate 555 is mounted above the worktable of the movable frame 52 and is connected to the grooving crossbeam 551. The second pressure plate 555 corresponds to the grooving component 554. A second pressing power component 556 that drives the second pressure plate 555 to rise and fall is provided on the grooving crossbeam 551. The grooving slide 552 and the grooving component 554 are driven to move on the grooving beam 551 by the grooving transverse moving force component 553. During the movement, the grooving component 554 processes the required groove on the surface of the plate, which has high processing efficiency and reduces the number of subsequent processing steps. The second pressing force component 556 cooperates with the second pressing plate 555 to press the plate during grooving, thereby improving the accuracy of grooving.

[0065] In this embodiment, the grooving component 554 is a "V" shaped cutter. In other embodiments, the grooving component 554 may also adopt other types of cutters depending on the groove to be machined.

[0066] Furthermore, the grooving module 55 also includes a grooving vertical moving force member 557, which drives the grooving crossbeam 551 to reciprocate along the conveying direction on the moving frame 52.

[0067] Optionally, both the grooving horizontal moving force component 553 and the grooving vertical moving force component 557 are motors, and the second pressing force component 556 is a cylinder.

[0068] Preferably, in order to improve the efficiency of grooving, one or more grooving modules 55 can be set up as needed.

[0069] Furthermore, the plate cutting and grooving machine 50 also includes a material guiding module 56 mounted on a movable frame 52. The material guiding module 56 includes a flow bar 561 disposed below the worktable of the movable frame 52 and a lifting power component 562 that drives the flow bar 561 to rise and fall. The worktable of the movable frame 52 is provided with a clearance groove corresponding to the flow bar 561. During feeding or discharging, the lifting power component 562 drives the flow bar 561 to rise to reduce the resistance of the plate movement. When cutting and grooving are required, the lifting power component 562 drives the flow bar 561 to fall so that the plate fits against the worktable, preventing the plate from shifting and improving processing accuracy. In this embodiment, the lifting power component 562 is a cylinder.

[0070] like Figure 12 As shown, the flipping machine 60 is positioned between the fourth conveyor table 24 and the unloading machine 70. The flipping machine 60 can flip the processed boards 180° to facilitate unloading and stacking by the unloading machine 70.

[0071] Please see Figure 3 and Figure 12 The structure of the unloading machine 70 is the same as that of the loading machine 10, and will not be described again here.

[0072] During processing, the feeding machine 10 picks up the sheet material and transfers it to the first conveyor table 21. After being cleaned by the cleaning component 211 on the first conveyor table 21, the sheet material continues to be conveyed to the second conveyor table 22 and the third conveyor table 23. On the third conveyor table 23, the sheet material is preheated by the heating component 231. After preheating, the sheet material enters the double-sided gluing machine 30 to apply PUR hot glue to both the top and bottom surfaces. The glued sheet material and the roll material on the first unwinding position 221 and the second unwinding position 48 converge at the input end of the laminating machine 40 and enter the laminating machine. The boards are pressurized and laminated in the repress laminating machine 40. After lamination, a protective film is applied to the output end of the repress laminating machine 40. Then, the boards covered with the protective film enter the board cutting and grooving machine 50 and are cut into boards of the required size according to the needs. Grooves can also be processed on the surface of the boards according to the needs. The cut and processed boards are conveyed to the flipping machine 60 via the fourth conveyor table 24. The flipping machine 60 flips the boards 180° and then transfers them to the unloading machine 70. The unloading machine 70 transfers the processed boards from the production line to other places.
