Description

Technical Field

[0001] This application relates to the field of lamination processing, and in particular to lamination equipment and processing methods for packaging bags. Background Technology

[0002] Lamination, also known as "plastic coating," "adhesive mounting," or "film application," refers to the process of applying a transparent plastic film to the surface of printed materials through heat and pressure. This process protects the material and enhances its gloss. Lamination is a major post-printing process where a plastic film coated with adhesive is bonded to paper printed materials through heating and pressure, forming a paper-plastic composite product. It is one of the most common post-printing processes for paper printed materials.

[0003] Applying a film to packaging bags used in daily life not only improves their toughness but also provides protection against moisture, water, dirt, abrasion, folding, and chemical corrosion, thus enhancing their durability.

[0004] Traditional laminating equipment uses lightweight and mostly transparent films to cover packaging bags. These films are designed to prevent scratches, water, or oil stains. They often need to be pulled a considerable distance by a traction device. During this process, due to their lightweight nature, the films are prone to sidewall curling or shaking in the air, which affects the ease and smoothness of subsequent application to the packaging bags. Summary of the Invention

[0005] The purpose of this application is to address the problem mentioned in the background art that the functional films used to cover packaging bags are lightweight and mostly transparent films, with functions such as scratch resistance, waterproofing, or oil resistance. They often need to be pulled by a traction device over a long distance. During this process, due to the lightweight nature of the functional film, it is prone to sidewall curling or shaking in the air, which affects the ease of application and the flatness of the application of the functional film on the packaging bag. This application provides a laminating equipment and processing method for packaging bags.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A laminating machine for packaging bags includes a processing table. Two symmetrical support frames are fixed at one end of the processing table, and a film roller is rotatably connected between the two support frames. Two sets of support mechanisms are arranged on both sides of the processing table, and a pulling mechanism is arranged on the support mechanism. A laminating machine is installed at the end of the processing table away from the film roller, and a take-up roller is arranged at the end of the processing table close to the laminating machine. Support legs are rotatably connected to both ends of the take-up roller. A take-up motor is fixed on one of the support legs, and the output end of the take-up motor passes through the support leg and is fixedly connected to the take-up roller. A limit roller is arranged at the end of the processing table close to the laminating machine, and support legs are rotatably connected to both ends of the limit roller. A control panel is installed on one side of the processing table.

[0008] By adopting the above technical solution, the film is pulled out from the film roller, passes through the support mechanism, and then both sides of the film pass through the traction mechanism after passing through the support mechanism. Finally, the film passes between the limiting roller and the processing table, making the film horizontal with the laminating machine. Then, the film passes through the laminating machine and is directly wound onto the take-up roller. When the film passes through the support mechanism, the support mechanism supports the film. At the same time, the film moves and drives the support mechanism. The support mechanism drives the traction mechanism to pull the two sides of the film, thereby reducing the possibility of shaking during the traction process. At the same time, it can pull the two ends of the film to reduce the possibility of folding on both sides during the traction process. Pulling the film to both sides can reduce the possibility of wrinkles during the traction process, ensuring the convenience and flatness of the functional film on the packaging bag.

[0009] Furthermore, the support mechanism includes two support rods symmetrically arranged on both sides of the processing table. One end of each support rod is provided with an adjustment component, and the end of the support rod away from the adjustment component is fixed with a support block. A support roller one is rotatably connected between the two support blocks, and a support roller two is provided between the two support blocks. Both ends of the support roller two are provided with abutment components.

[0010] By adopting the above technical solution, after the film is pulled out from the film roller, it passes between support roller one and support roller two. Support roller one and support roller two clamp the film. When the winding roller pulls the film, the film passes through support roller one and support roller two. Support roller one and support roller two rotate with the movement of the film, thereby reducing the possibility of the film shaking or folding during the traction process.

[0011] Furthermore, the abutment component includes a sliding block slidably connected to the support block, the support block having a sliding groove, the sliding block being located within the sliding groove, and two abutment springs being provided within the sliding groove. Both ends of the abutment springs are fixedly connected to the support block and the sliding block, and both ends of the second support roller are rotatably connected to the sliding block.

[0012] By adopting the above technical solution, the sliding blocks at both ends of the second support roller move closer to the first support roller under the support of the contact spring. The first and second support rollers clamp the film, thereby adapting to films of different thicknesses and reducing the possibility of the film slipping between the first and second support rollers.

[0013] Furthermore, the adjustment assembly includes a fixed block, which is fixedly connected to the processing table. An adjustment base cylinder is fixed on the fixed block, which passes through the fixed block. The adjustment base cylinder is sleeved on the support rod and slidably connected to the support rod. An adjustment bolt is threadedly connected to the fixed block, which passes through the fixed block and the adjustment base cylinder, and the adjustment bolt abuts against the support rod.

[0014] By adopting the above technical solution, the adjusting bolt is turned to disengage the support rod from the adjusting bolt, and then the support rod slides on the adjusting bottom cylinder, allowing support roller one and support roller two to descend, so that the film can pass through between support roller one and support roller two. This makes it easy to pass the film through support roller one and support roller two, and the tension of the film can also be adjusted by raising and lowering support roller one and support roller two.

[0015] Furthermore, the pulling mechanism includes a connecting block fixed on the support block. A first pulling roller is provided on the side of the connecting block near the processing table, and a second pulling roller is provided on one side of the first pulling roller. Both ends of the first and second pulling rollers are rotatably connected to connecting rods. The connecting rods are fixedly connected to the connecting block. A first driving component is provided between the first pulling roller and the connecting block, and a second driving component is provided between the second pulling roller and the connecting block.

[0016] By adopting the above technical solution, the two sides of the film pass through the corresponding traction roller 1 and traction roller 2. The film drives support roller 1, support roller 1 drives drive component 1, drive component 1 drives drive component 2. The rotation of traction roller 1 and traction roller 2 pulls the film outward during the movement, thereby reducing the possibility of wrinkles and edge flipping during the movement of the film, ensuring the convenience and flatness of subsequent application of the functional film on the packaging bag.

[0017] Furthermore, the drive assembly includes a bevel gear rotatably connected to the support block. One end of the support roller passes through the support block and is fixedly connected to the bevel gear. A bevel gear 2 is provided on one side of the bevel gear 1, and the bevel gear 1 and bevel gear 2 mesh with each other. A rotating shaft is fixed on the bevel gear 2, and a drive block 1 is rotatably connected to the rotating shaft. The rotating shaft passes through the drive block 1, and the drive block 1 is fixedly connected to the connecting block. A transmission gear 1 is fixed on the drive block 1, and a transmission gear 2 is provided on one side of the transmission gear 1. The transmission gear 2 is rotatably connected to the drive block 1, and the transmission gear 1 and transmission gear 2 mesh with each other. A drive wheel 1 is fixed on the transmission gear 2. One end of the traction roller 1 passes through the connecting rod and is fixedly connected to the drive wheel 2. A drive belt 1 is drivingly connected between the drive wheel 1 and the drive wheel 2.

[0018] By adopting the above technical solution, the support roller 1 drives the bevel gear 1 to rotate, the bevel gear 1 drives the bevel gear 2 to rotate, the transmission gear 2 drives the drive wheel 1 to rotate, the drive wheel 1 drives the drive wheel 2 to rotate via the drive belt 1, and the drive wheel 2 drives the traction roller 1 to rotate. Thus, during the movement of the film, the film can be pulled outward simultaneously, further reducing the possibility of wrinkles appearing on the film during movement.

[0019] Furthermore, the second drive assembly includes a second drive block, which is fixedly connected to a connecting block. The rotating shaft passes through the second drive block, and a third drive wheel is fixed on one end of the rotating shaft near the second drive block. One end of the second traction roller passes through a connecting rod and is fixed with a fourth drive wheel. A second drive belt is drivingly connected between the third drive wheel and the fourth drive wheel.

[0020] By adopting the above technical solution, the rotating shaft drives the third drive wheel to rotate, and the third drive wheel drives the fourth drive wheel to rotate via the drive belt, thereby enabling the second traction roller to rotate simultaneously with the first traction roller, further reducing the possibility of wrinkles appearing on the film during movement.

[0021] A processing method for a laminating equipment used in packaging bag processing, applicable to the aforementioned laminating equipment for packaging bag processing, is as follows:

[0022] S1: First, place both ends of the film roller that is winding the film onto the support frame, and let the two ends of the film roller be rotatably connected to the support frame. Then, find one end of the film from the film roller.

[0023] S2: The film head found on the film roller is passed through support roller one and support roller two, so that support roller one and support roller two can clamp the film.

[0024] S3: The film passing between support roller 1 and support roller 2 passes through both sides of the corresponding traction roller 1 and traction roller 2;

[0025] S4: Then the film passes under the limiting roller, then through the laminator, and after passing through the laminator, it is directly wound onto the take-up roller;

[0026] S5: Finally, use the control panel to control the winding shaft to slowly wind up the film, while the laminator uses the film passing through it to laminate the packaging bag.

[0027] In summary, this application includes at least one of the following beneficial effects;

[0028] 1. In this application, the film passes between support roller 1 and support roller 2. The sliding blocks at both ends of support roller 2 move closer to support roller 1 under the support of the anti-spring, causing support roller 2 to move closer to support roller 1. Support roller 1 and support roller 2 clamp the film. Then, the two sides of the film pass between the corresponding traction roller 1 and traction roller 2. As the film moves, it drives support roller 1. Support roller 1 uses drive component 1 and drive component 2 to drive traction roller 1 and traction roller 2 to pull the film to both sides. This reduces the possibility of the film shaking during the traction process. At the same time, it can pull the two ends of the film to reduce the possibility of the film folding on both sides during the traction process. Pulling the film to both sides can reduce the possibility of wrinkles in the film during the traction process, thus ensuring the convenience and flatness of the functional film when it is subsequently applied to the packaging bag.

[0029] 2. In this application, by disengaging the support rod from the adjusting bolt, and then sliding the support rod on the adjusting base cylinder, the first and second support rollers are lowered, allowing the film to pass between the first and second support rollers. Then, the support rod is slid upward in the adjusting base cylinder, and the adjusting bolt is retightened so that the adjusting bolt contacts the support rod, maintaining the support rod at the required height. This achieves the purpose of facilitating the passing of the film between the first and second support rollers, while also allowing the tension of the film to be adjusted by raising and lowering the first and second support rollers.

[0030] 3. In this application, when the film passes between support roller 1 and support roller 2, the sliding blocks at both ends of support roller 2 move closer to support roller 1 under the support of the anti-spring, and support roller 2 moves closer to support roller 1. Support roller 1 and support roller 2 clamp the film, thereby achieving the purpose of adapting to films of different thicknesses and reducing the possibility of the film slipping between support roller 1 and support roller 2.

[0039] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0040] This application discloses a laminating device and a processing method for packaging bags.

[0041] Reference Figure 1 , Figure 2 and Figure 3A laminating equipment for packaging bag processing includes a processing table 1. Two symmetrical support frames 2 are fixed at one end of the processing table 1, and a film roller 3 is rotatably connected between the two support frames 2. Two sets of support mechanisms 4 are provided on both sides of the processing table 1, and a pulling mechanism 5 is provided on the support mechanism 4. A laminating machine 10 is installed at the end of the processing table 1 away from the film roller 3. A take-up roller 7 is provided at the end of the processing table 1 near the laminating machine 10. Support legs are rotatably connected to both ends of the take-up roller 7. A take-up motor 8 is fixed on one of the support legs. The output end of the take-up motor 8 passes through the support leg and is fixedly connected to the take-up roller 7. A limit roller 6 is provided at the end of the processing table 1 near the laminating machine 10. Support legs are rotatably connected to both ends of the limit roller 6. A control panel 9 is installed on one side of the processing table 1. When using the laminating equipment for packaging bag processing, first place the film roller 3 with the film wound on it between the two support frames 2, allowing the film roller 3 to be rotatably connected to the support frame 2. Then, pull out the film from the film roller 3, allowing it to pass through the support mechanism 4. Next, allow both sides of the film to pass through the support mechanism 4 and then through the pulling mechanism 5. Finally, pass the film between the limiting roller 6 and the processing table 1, ensuring the film is horizontal with the laminating machine 10. Then, pass the film through the laminating machine 10, and after passing through, directly wind it onto the take-up roller 7. Then, use the control panel 9 to start the take-up motor 8. The take-up motor 8 rotates the take-up shaft, which winds up the film. During the winding process, the laminating machine 10 uses the passed-through film to laminate the packaging bags placed on the laminating machine 10. As the film passes through the support mechanism 4, the support mechanism 4 supports the film. Simultaneously, the film moves along with the support mechanism 4, which in turn drives the pulling mechanism 5. The pulling mechanism 5 pulls on both sides of the film. By allowing the film from the film roller 3 to pass through the support mechanism 4, which supports the film, and simultaneously drives the pulling mechanism 5, the film is pulled. This reduces the possibility of the film shaking during traction and also pulls both ends of the film, reducing the possibility of folding. Furthermore, pulling the film to both sides reduces the possibility of wrinkles during traction, ensuring the ease and smoothness of subsequent application of the functional film to the packaging bag.

[0042] Reference Figure 1 , Figure 2 and Figure 4The support mechanism 4 includes two support rods 41 symmetrically arranged on both sides of the processing table 1. One end of the support rod 41 is provided with an adjustment component 46. The end of the support rod 41 away from the adjustment component 46 is fixed with a support block 42. A support roller 43 is rotatably connected between the two support blocks 42. A support roller 44 is provided between the two support blocks 42. Both ends of the support roller 44 are provided with abutment components 45. After the film is pulled out from the film roller 3, it passes between support roller 1 43 and support roller 2 44. Then, the height of the support rod 41 is adjusted by the adjusting component 46 so that support roller 1 43 and support roller 2 44 are at a suitable height. Support roller 2 44 approaches support roller 1 43 with the support of the abutment component 45. Support roller 1 43 and support roller 2 44 clamp the film. When the take-up roller 7 pulls the film, the film passes through support roller 1 43 and support roller 2 44. Support roller 1 43 and support roller 2 44 rotate as the film moves. By using support roller 1 43 and support roller 2 44 to support the passing film, the possibility of the film shaking or folding during the traction process can be reduced.

[0043] Reference Figure 2 and Figure 4 The contact component 45 includes a sliding block 451 slidably connected to the support block 42. The support block 42 has a sliding groove 452, and the sliding block 451 is located within the sliding groove 452. Two contact springs 453 are installed within the sliding groove 452. Both ends of the contact springs 453 are fixedly connected to the support block 42 and the sliding block 451. Both ends of the second support roller 44 are rotatably connected to the sliding block 451. When the film passes between the first support roller 43 and the second support roller 44, the sliding blocks 451 at both ends of the second support roller 44 move closer to the first support roller 43 under the support of the contact springs 453, causing the second support roller 44 to move closer to the first support roller 43. The first support roller 43 and the second support roller 44 clamp the film. The support of the sliding blocks 451 by the contact springs 453 allows the second support roller 44 to clamp the film with the first support roller 43, thus adapting to films of different thicknesses and reducing the possibility of the film slipping between the first support roller 43 and the second support roller 44.

[0044] Reference Figure 1 and Figure 2The adjusting component 46 includes a fixing block 461, which is fixedly connected to the processing table 1. An adjusting base cylinder 462 is fixed on the fixing block 461. The adjusting base cylinder 462 passes through the fixing block 461 and is sleeved on the support rod 41 and slidably connected to the support rod 41. An adjusting bolt 463 is threadedly connected to the fixing block 461. The adjusting bolt 463 passes through the fixing block 461 and the adjusting base cylinder 462 and abuts against the support rod 41. When the film needs to pass between support roller 1 43 and support roller 2 44, for ease of operation, first tighten the adjusting bolt 463 to move it on the fixed block 461, allowing the support rod 41 to disengage from the adjusting bolt 463. Then, slide the support rod 41 on the adjusting base cylinder 462, lowering support roller 1 43 and support roller 2 44. Then, allow the film to pass between support roller 1 43 and support roller 2 44. Next, slide the support rod 41 upward in the adjusting base cylinder 462, and then retighten the adjusting bolt 463 to contact the support rod 41, maintaining the support rod 41 at the required height. By disengaging the adjusting bolt 463 from contacting the support rod 41, the support rod 41 can slide on the adjusting base cylinder 462, facilitating the passing of the film between support roller 1 43 and support roller 2 44. Simultaneously, the tension of the film can be adjusted by raising and lowering support roller 1 43 and support roller 2 44.

[0045] Reference Figure 4 , Figure 5 and Figure 6 The traction mechanism 5 includes a connecting block 54 fixed on the support block 42. A first traction roller 51 is provided on the side of the connecting block 54 near the processing table 1. A second traction roller 52 is provided on one side of the first traction roller 51. Both ends of the first traction roller 51 and the second traction roller 52 are rotatably connected to a connecting rod 53. The connecting rod 53 is fixedly connected to the connecting block 54. A first drive assembly 55 is provided between the first traction roller 51 and the connecting block 54. A second drive assembly 56 is provided between the second traction roller 52 and the connecting block 54. After the film passes between support roller 1 43 and support roller 2 44, both sides of the film pass between the corresponding traction roller 1 51 and traction roller 2 52. Traction roller 1 51 and traction roller 2 52 are rubber rollers. When the film is wound up by the winding roller 7, the film drives support roller 1 43, support roller 1 43 drives drive assembly 1 55, drive assembly 1 55 drives traction roller 1 51 to rotate, and at the same time drive assembly 1 55 drives drive assembly 2 56 to rotate, drive assembly 2 56 drives traction roller 2 52 to rotate. The rotation of traction roller 1 51 and traction roller 2 52 pulls the film outward during the movement. By using traction roller 1 51 and traction roller 2 52 to pull the film, the possibility of wrinkles and edge flipping during the movement of the film can be reduced, ensuring the convenience and flatness of subsequent application of the functional film on the packaging bag.

[0046] Reference Figure 4 , Figure 5 and Figure 6 The drive assembly 55 includes a bevel gear 551 rotatably connected to the support block 42. One end of the support roller 43 passes through the support block 42 and is fixedly connected to the bevel gear 551. A bevel gear 552 is provided on one side of the bevel gear 551, and the bevel gear 551 meshes with the bevel gear 552. A rotating shaft 554 is fixed on the bevel gear 552, and a drive block 553 is rotatably connected to the rotating shaft 554. The rotating shaft 554 passes through the drive block 553, and the drive block 553 is fixedly connected to the connecting block 54. A drive block 553 is fixed with a transmission gear 555. A transmission gear 556 is provided on one side of the transmission gear 555. The transmission gear 556 is rotatably connected to the drive block 553. The transmission gear 555 and the transmission gear 556 mesh with each other. A drive wheel 558 is fixed on the transmission gear 556. One end of the pull roller 51 passes through the connecting rod 53 and is fixed with a drive wheel 559. A drive belt 557 is connected between the drive wheel 558 and the drive wheel 559. When the support roller 43 is rotated by the film, the support roller 43 rotates the bevel gear 551, which in turn drives the bevel gear 552 to rotate. The bevel gear 552 drives the rotating shaft 554 to rotate, which rotates on the drive block 553. The rotating shaft 554 drives the transmission gear 555, which in turn drives the transmission gear 556 to rotate. The transmission gear 556 drives the drive wheel 558 to rotate, which in turn drives the drive wheel 559 to rotate via the drive belt 557. The drive wheel 559 drives the traction roller 51 to rotate, which pulls the film outward. By having the traction roller 51 pull the film outward while the film is rotating with the support roller 43, the film can be pulled outward synchronously during the film's movement, further reducing the possibility of wrinkles appearing during the film's movement.

[0047] Reference Figure 3 and Figure 6The second drive assembly 56 includes a second drive block 561, which is fixedly connected to a connecting block 54. A rotating shaft 554 passes through the second drive block 561. A third drive wheel 562 is fixed to one end of the rotating shaft 554 near the second drive block 561. One end of the second traction roller 52 passes through a connecting rod 53 and is fixed with a fourth drive wheel 563. A second drive belt 564 drives the second traction roller 52 to rotate outward. When the rotating shaft 554 rotates, it drives the third drive wheel 562 to rotate. The third drive wheel 562 drives the fourth drive wheel 563 to rotate via the drive belt. The fourth drive wheel 563 drives the second traction roller 52 to rotate outward. By driving the third drive wheel 562 when the rotating shaft 554 rotates, the second traction roller 52 can rotate simultaneously with the first traction roller 51, further reducing the possibility of wrinkles appearing on the film during movement.

[0048] This application also provides a processing method for a laminating device used in packaging bag processing, the processing method being as follows:

[0049] S1: First, place both ends of the film roller 3 that is wound with film onto the support frame 2, so that both ends of the film roller 3 are rotatably connected to the support frame 2, and then find one end of the film from the film roller 3;

[0050] S2: The film head found from the film roller 3 is passed through support roller 1 43 and support roller 2 44, so that support roller 1 43 and support roller 2 44 can clamp the film.

[0051] S3: The film passing between support roller 1 43 and support roller 2 44 passes between the corresponding traction roller 1 51 and traction roller 2 52 on both sides.

[0052] S4: Then the film is passed from below the limiting roller 6 and then passed through the laminator 10. After passing through the laminator 10, the film is directly wound onto the take-up roller 7.

[0053] S5: Finally, control the winding shaft to slowly wind up the film using the control panel 9, while the laminating machine 10 uses the film passing through it to laminate the packaging bag.

[0054] Working principle: When using this laminating equipment for packaging bag processing, first place the film roller 3 with the film wound on it between the two support frames 2, allowing the film roller 3 to rotate and connect with the support frame 2. Then, pull out the film from the film roller 3, and simultaneously turn the adjusting bolt 463 to move it on the fixed block 461, allowing the support rod 41 to disengage from the adjusting bolt 463. Then, let the support rod 41 slide on the adjusting bottom cylinder 462, allowing the support roller 1 43 and support roller 2 44 to descend. Then, the film passes between the support roller 1 43 and support roller 2 44. The sliding blocks 451 at both ends of the support roller 2 44 move closer to the support roller 1 43 under the support of the contact spring 453, allowing the support roller 2 44 to move closer to the support roller 1 43. The support roller 1 43 and support roller 2 44 clamp the film. Then, the two sides of the film are pulled from the corresponding pull roller 1 51 and pull roller 2 52. The film passes through the support rollers 1-43 and 2-44 in the same way, and then passes between the limit roller 6 and the processing table 1, so that the film is horizontal with the laminating machine 10. The film then passes through the laminating machine 10 and is directly wound onto the take-up roller 7. The take-up motor 8 is started by the control panel 9. The take-up motor 8 drives the take-up shaft to rotate, and the take-up shaft winds up the film. During the winding process, the film drives the support roller 1-43 to rotate. The support roller 1-43 drives the drive assembly 1-55, and the drive assembly 1-55 drives the pull roller 1-51 to rotate. At the same time, the drive assembly 1-55 drives the drive assembly 2-56 to rotate, and the drive assembly 2-56 drives the pull roller 2-52 to rotate. The rotation of the pull roller 1-51 and the pull roller 2-52 pulls the film outward during the movement. Finally, the film passes through the laminating machine 10 and is used to laminate the packaging bag.
