Description

Technical Field

[0001] This utility model relates to the field of release paper processing technology, and in particular to a multifunctional release paper coating and drying device. Background Technology

[0002] The adhesive coating process is a crucial step in release paper production. The uniformity of the coating, the thickness of the layer, and the curing effect of the adhesive all directly affect the performance of the release paper. Traditional adhesive coating methods typically use techniques such as roller coating, spraying, and dip coating, employing mechanical equipment to precisely control the coating amount and uniformity, ensuring that the adhesive effectively covers the surface of the release paper. After coating, the release paper needs to undergo a drying process to remove solvents or moisture, allowing the adhesive layer to solidify stably. The drying process directly impacts the quality of the release paper, requiring not only efficient dehumidification but also avoiding overheating or incomplete drying that could lead to adhesive failure or uneven coating.

[0003] For example, Chinese invention patent application number 202310940298.3 discloses a multifunctional release paper coating and drying device, including a mounting frame with a conveyor belt; a cleaning component mounted on the mounting frame for cleaning debris from the release paper's coating surface; a coating component mounted on the mounting frame, located behind the cleaning component, for coating the release paper with adhesive; and a baking component mounted on the mounting frame, located behind the coating component, for drying the coated release paper. The release paper is fed sequentially into the cleaning component by starting the conveyor belt, where its surface is cleaned. Then, it is fed into the coating component for coating. The coating component applies adhesive to the cleaned release paper surface. After coating, the release paper is baked by the baking component, and finally, the release paper is discharged, completing the coating process. This solves the problem that traditional release paper coating equipment can only coat release paper of a fixed width, and cannot coat release paper of different widths.

[0004] While the above solutions can achieve beneficial results in release paper production, insufficient tension during the conveying process can easily lead to wrinkles or skewing. This can result in uneven coating during gluing, affecting the quality and performance of the release paper. Furthermore, it can prevent precise execution of processes such as gluing and drying, leading to a decline in product quality and, in severe cases, damage to the release paper, resulting in material waste. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional release paper coating and drying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional release paper coating and drying device, comprising a worktable, two sets of support blocks fixedly connected to the top of the worktable, active rollers rotatably connected between the two sides of the inner walls of the two sets of support blocks, one end of each of the two active rollers penetrating to the outside of the support block and fixedly connected to a pulley, a driving assembly capable of driving the active rollers to rotate is provided on one side of the worktable, sliding grooves are provided on both sides of the inner walls of the two sets of support blocks, a moving block is slidably connected to the inner wall of the sliding groove, a clamping assembly is provided on the top of the moving block, a coating assembly is provided on the top of the worktable, two gantry frames are fixedly connected to the top of the worktable, two guide rods are fixedly connected to the top of one of the gantry frames, a threaded block is slidably connected to the outer walls of the two guide rods, a lifting assembly is provided on the threaded block, a drying assembly is provided on one side of the threaded block, and a heating assembly is provided on the inner wall of the worktable.

[0007] By setting up an active roller, which works in conjunction with the clamping roller, the release paper is moved by the active roller during the clamping process. During this process, the pulling of the active roller keeps the release paper under tension, smooths out any wrinkles, and prevents the release paper from moving around, which facilitates subsequent gluing and drying.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor 1 fixedly mounted on one side of the worktable, and a pulley 2 is fixedly connected to the output end of the motor 1 and the outer wall of one of the drive rollers.

[0010] The outer walls of both pulleys 1 and 2 are connected by belt drive. Through the synchronous drive of pulley 1, the release paper can be moved stably.

[0011] As a further description of the above technical solution:

[0012] The clamping assembly includes a movable rod fixedly mounted on the top of the movable block, and a spring is sleeved on the outer wall of the movable rod.

[0013] One end of the moving rod slides through the outside of the support block. Through the compression of the spring, the clamping roller can be pressed down, increasing the friction between the release paper and the surface of the drive roller, so that when the drive roller rotates, it drives the release paper forward.

[0014] As a further description of the above technical solution:

[0015] The adhesive application assembly includes two fixed blocks fixedly connected to the top of the workbench. A motor is mounted on one side of one of the fixed blocks, and an adhesive application roller is rotatably connected between the opposite sides of the two fixed blocks.

[0016] The output end of the second motor passes through the interior of the fixed block and is fixedly connected to the glue-coating roller. By setting the glue-coating roller, the glue material can be applied to the surface of the glue-coating roller. When the glue-coating roller rotates, the glue material is evenly applied to the release paper.

[0017] As a further description of the above technical solution:

[0018] A glue storage tank is fixedly connected between the two fixed blocks on opposite sides. The top surface of the glue storage tank has several drainage holes, and a cover plate is hinged to the top of the glue storage tank.

[0019] The interior of the glue storage box is used to hold the glue material. The glue material enters the surface of the glue roller through the perforation, and the bottom of the glue storage box is slidably connected to the glue roller, which can carry out excess material along the gap. When passing through the outer wall of the glue storage box, excess glue material is blocked. By the continuous rotation of the glue roller, the excess material is utilized.

[0020] As a further description of the above technical solution:

[0021] The lifting assembly includes a support plate and a motor. The support plate is fixedly installed between the top ends of two guide rods, and the motor is fixedly installed on the top of the support plate. A threaded rod is fixedly connected to the output end of the motor.

[0022] One end of the threaded rod is rotatably connected to the top of one of the gantry frames, and the outer wall of the threaded rod is threadedly connected to the inside of the threaded block.

[0023] As a further description of the above technical solution:

[0024] The drying assembly includes several hot air blowers fixedly installed on one side of the threaded block, and a heating cover is fixedly connected to the bottom of each hot air blower.

[0025] By setting up a heating hood, the hot air generated by the hot air blower can be amplified and maintained within a certain range, resulting in better drying effect.

[0026] As a further description of the above technical solution:

[0027] The heating assembly includes a heating frame fixedly installed on the inner wall of the workbench, and a plurality of heating wires are fixedly installed between the two sides of the inner wall of the heating frame.

[0028] The heating frame is tilted so that it can heat and dry the centrifugal paper evenly. The heating wire can also heat the bottom of the centrifugal paper, making the drying effect better.

[0029] As a further description of the above technical solution:

[0030] A pressure roller is rotatably connected between the two sides of the inner wall of the two gantry frames, and a clamping roller is rotatably connected to the opposite side of the two sets of moving blocks.

[0031] By setting up a pressure roller, the glue coating component can apply the glue more evenly during the glue coating process. At the same time, the clamping roller can reduce sliding friction when the release paper moves, thus reducing damage to the release paper.

[0042] Reference Figure 1-4 This utility model provides a multifunctional release paper coating and drying device, comprising a workbench 1, with two sets of support blocks 2 fixedly connected to the top of the workbench 1. Active rollers 3 are rotatably connected between the two sides of the inner walls of the two sets of support blocks 2. One end of each active roller 3 extends through to the outside of the support block 2 and is fixedly connected to a pulley 4. A drive assembly capable of driving the active rollers 3 is provided on one side of the workbench 1. Slide grooves 5 are provided on both sides of the inner walls of the two sets of support blocks 2. Moving blocks 6 are slidably connected to the inner walls of the slide grooves 5. A clamping assembly is provided on the top of the moving blocks 6.

A lifting assembly is provided on the threaded blocks 9. A drying component is provided on one side of the threaded block 9, and a heating component is provided on the inner wall of the workbench 1. By setting the active roller 3, it can cooperate with the clamping roller 28 to move the release paper by being driven by the active roller 3 during the clamping process. During this process, the pulling of the active roller 3 will keep the release paper under tension, smooth out any wrinkles, and prevent the release paper from moving around, which will facilitate subsequent gluing and drying. There are two support blocks 2 in each group. Through the cooperation of the pulley 4, the active roller 3, the drive component and the clamping component, the flatness and stability of the release paper during the conveying process are ensured, the slippage and wrinkles of the release paper during the conveying process are prevented, the stability and accuracy of the release paper gluing process are ensured, the uneven gluing caused by wrinkling is avoided, the losses caused by release paper wrinkling are reduced, and the production quality is improved.

[0043] The drive assembly includes a motor 10 fixedly mounted on one side of the worktable 1. The output end of the motor 10 and the outer wall of one of the drive rollers 3 are both fixedly connected to pulleys 11. The outer walls of the two pulleys 4 and pulleys 11 are connected by belt drive. Through the synchronous transmission of pulleys 4, the release paper can be moved stably. The clamping assembly includes a moving rod 12 fixedly mounted on the top of the moving block 6. A spring 13 is sleeved on the outer wall of the moving rod 12. One end of the moving rod 12 slides through to the outside of the support block 2. Through the compression of the spring 13, the clamping roller 28 can be pressed down, increasing the friction between the release paper and the surface of the drive roller 3, so that when the drive roller 3 rotates, it drives the release paper forward.

[0044] The adhesive application assembly includes two fixed blocks 15 fixedly connected to the top of the workbench 1. A motor 14 is mounted on one side of one of the fixed blocks 15. An adhesive application roller 16 is rotatably connected between the opposite sides of the two fixed blocks 15. The output end of the motor 14 passes through the interior of the fixed block 15 and is fixedly connected to the adhesive application roller 16. The adhesive application roller 16 allows adhesive material to be applied to its surface. As the adhesive application roller 16 rotates, the adhesive material is evenly applied to the release paper. The two fixed blocks 15 are rotatably connected between their opposite sides. A glue storage tank 17 is fixedly connected to one side. Several holes 18 are opened on the top surface of the glue storage tank 17. A cover plate 19 is hinged to the top of the glue storage tank 17. The inside of the glue storage tank 17 is used to hold the glue material. The glue material enters the surface of the glue coating roller 16 through the holes 18. The bottom of the glue storage tank 17 is slidably connected to the glue coating roller 16, which can carry out the excess material along the gap. When passing through the outer wall of the glue storage tank 17, the excess glue material is blocked. The glue coating roller 16 rotates continuously, so that the excess material can be utilized.

[0045] The lifting assembly includes a support plate 20 and a motor 21. The support plate 20 is fixedly installed between the tops of two guide rods 8, and the motor 21 is fixedly installed on the top of the support plate 20. The output end of the motor 21 is fixedly connected to a threaded rod 22. One end of the threaded rod 22 is rotatably connected to the top of one of the gantry frames 7. The outer wall of the threaded rod 22 is threadedly connected to the inside of the threaded block 9. The drying assembly includes several hot air blowers 23 fixedly installed on one side of the threaded block 9. The bottom of the hot air blower 23 is fixedly connected to a heating cover 24. Through the setting of the heating cover 24, the hot air generated by the hot air blower 23 can be amplified and kept within a certain range, so as to improve the drying effect.

[0046] The heating assembly includes a heating frame 25 fixedly installed on the inner wall of the workbench 1. Several heating wires 26 are fixedly installed between the two sides of the inner wall of the heating frame 25. The heating frame 25 is inclined so as to heat and dry the centrifugal paper evenly. The heating wires 26 can also heat the bottom of the centrifugal paper, making the drying effect better. Pressure rollers 27 are rotatably connected between the two sides of the inner wall of the two gantry frames 7. Clamping rollers 28 are rotatably connected to the opposite side of the two sets of moving blocks 6. By setting the pressure rollers 27, the glue coating assembly can apply the glue more evenly during the glue coating process. At the same time, by setting the clamping rollers 28, the sliding friction can be reduced when the release paper moves, reducing damage to the release paper.

[0047] Working principle: First, the release paper to be coated is passed between the drive roller 3 and the clamping roller 27. At this time, the moving rods 12 on both sides can be moved to drive the moving block 6 to move upward along the slide 5, so that the spring 13 is squeezed and the clamping roller 28 is moved upward, thus leaving a gap to facilitate the insertion of the release paper. Then, the moving rods 12 are released, so that the spring 13 presses the moving block 6 downward, and the clamping roller 28 presses the drive roller 3 downward, increasing the friction. Then, the motor 10 can be started, and the output end rotates to drive the pulley 11 to rotate. Under the action of belt drive, the other pulley 11 also rotates. At the same time, because one of the drive rollers 3 is also equipped with a pulley 4, they rotate synchronously. And under the drive of another belt, the other drive roller 3 is driven to rotate, thus making the two drive rollers 3 rotate synchronously, so that the release paper can move forward.

[0048] When the release paper moves to the pressure roller 27, it passes through the bottom of the pressure roller 27 to keep the release paper flat before coating. Then, the coating material can be poured into the glue storage tank 17. The coating material drips onto the coating roller 16 through the drain hole 18. Then, the motor 14 is started, and the output end rotates to drive the coating roller 16 to rotate, so that the glue adheres to the inside of the coating roller 16. Then, through the contact between the coating roller 16 and the release paper, the glue is coated onto the release paper. As the coating roller 16 rotates towards the drying component, the glue will be scraped through the bottom of the glue storage tank 17, so that the excess glue is located on the side of the release paper that has not been coated. The rotation of the coating roller 16 allows the excess glue to be reused, thereby saving raw materials.

[0049] The coated release paper exits through the second pressing roller 27, and then the hot air blower 23 is activated to generate hot air to dry the surface of the release paper. When the coating is thick and a higher drying temperature is required, the motor 3 21 is activated, and the output end rotates to drive the threaded rod 22 to rotate, allowing the threaded block 9 to move downward along the guide rod 8, bringing the drying component closer to the release paper. When the temperature is high, simply reverse the drive of the motor 3 21 to move the drying component upward, thereby reducing the drying temperature. During drying, the heating wire 26 in the heating frame 25 can also be activated to heat and bake the other side of the release paper, making the heating and drying effect better. The heating frame 25 is placed at an angle, which makes the heating of the release paper more uniform. Then, the heated release paper can be passed between the other side's drive roller 3 and clamping roller 28. With the rotation of the motor 1 10, the drive roller 3 on one side feeds the release paper forward, while the drive roller 3 on the other side pulls the release paper forward, so that the release paper can be continuously fed while maintaining a certain tension, which is convenient for the staff to use.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
