Description

Technical Field

[0001] The invention relates to the technical field of production and packaging, in particular to a BOPP pearlescent film composite glue-coated trademark coating device. Background Art

[0002] In the field of modern commodity production and packaging, the quality and appearance of trademarks play a vital role in product identification, promotion and sales. With the continuous improvement of consumers' requirements for product quality and packaging, and the increasingly fierce market competition, the development of efficient and high-quality trademark coating equipment has become an urgent need in the industry.

[0003] There are often many problems with traditional trademark coating processes. For example, during the gluing process, due to the insufficient precision of the gluing equipment, it is easy to cause uneven gluing, which affects the bonding effect between the glue and the film and the appearance quality of the trademark. At the same time, the inefficiency of the drying process or the poor drying effect may cause incomplete curing of the glue, resulting in problems such as degumming of the trademark in subsequent use. During the composite process, previous devices may not be able to achieve precise pressure control and close fit of the two layers of film, thus affecting the firmness of the composite and the overall performance of the product. Moreover, during the entire production process, the tension control of the film is not stable enough, which easily causes deformation and wrinkles of the film, further reducing the quality and production efficiency of the product. In addition, the traditional device has a low degree of automation and requires a lot of manual intervention, which not only increases labor costs, but also makes it difficult to ensure the consistency and stability of production.

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] Example

[0034] Reference Figure 1-7A BOPP pearlescent film composite glue coating trademark coating device includes a frame 1, two mounting frames 3 are symmetrically mounted on the frame 1, each mounting frame 3 is mounted with a tensioning wheel 6 through a tensioning assembly, each tensioning assembly includes two symmetrically arranged tensioning frames 5, and each tensioning frame 5 is mounted on the mounting frame 3 through a connecting shaft 16, each tensioning frame 5 and the mounting frame 3 are jointly installed with a torsion spring 23, and the torsion spring 23 is sleeved on the connecting shaft 16; each tensioning frame 5 is provided with a movable groove 17, and both ends of the tensioning wheel 6 are slidably connected to the movable groove 1 corresponding to the position 7, a tensioning spring 18 is installed between the inner wall of each movable groove 17 and the tensioning wheel 6, and the tensioning spring 18 is located in the movable groove 17; it effectively maintains the stability of the tension of the film during the transmission process, prevents the film from wrinkling, deformation or excessive stretching due to improper tension, thereby ensuring the flatness and dimensional accuracy of the film, reducing the problems of uneven glue coating and loose composite due to fluctuations in film tension, improving the consistency and quality stability of the product, adapting to films of different specifications and materials, and being able to flexibly adjust the tension according to the characteristics of the film, thereby broadening the scope of application of the device to raw materials.

[0035] Two U-shaped slots 19 are symmetrically provided at the upper end of each mounting frame 3, wherein the two U-shaped slots 19 on one mounting frame 3 are jointly provided with a pearlescent film roller 4, and the two U-shaped slots 19 on the other mounting frame 3 are jointly provided with a composite film roller 10, and a drive motor is provided at one end of the composite film roller 10, and the drive motor is installed on the side wall of the mounting frame 3.

[0036] A gluing mechanism is also installed on the mounting frame 3 on which the pearlescent film roller 4 is clamped. The gluing mechanism includes a glue cylinder 24 and a glue barrel 2, and the glue barrel 2 is installed on the frame 1, and the glue cylinder 24 is fixedly installed on the mounting frame 3, a liquid pump is installed in the glue barrel 2, and the output end of the liquid pump is connected to the glue cylinder 24 through a connecting pipe 22; the gluing mechanism also includes a first motor 7, and the first motor 7 is fixedly installed on the mounting frame 3 at a corresponding position, the output end of the first motor 7 extends into the glue cylinder 24 and is installed with a glue leveling rack 26, a plurality of glue coating tubes 25 are evenly connected to the glue cylinder 24, the glue leveling rack 26 includes a central axis 2601, and the central axis 2601 is fixedly connected to the output end of the first motor 7, and the outer wall of the central axis 2601 is symmetrically arranged A plurality of glue pushing plates 2602 are provided, and both ends of each glue pushing plate 2602 are in contact with the inner wall of the glue cylinder 24, and the port of the connecting pipe 22 is located between two adjacent glue pushing plates 2602. The cooperation between the glue barrel 1 and the glue cylinder 24, and the precise delivery of the liquid pump ensure the continuity and stability of the glue supply and avoid the glue breaking phenomenon during the gluing process. The rotating movement of the glue leveling rack 26 can make the glue fully stirred and evenly distributed in the glue cylinder 24, so that the pearlescent film can be evenly coated through the glue coating tube 25, avoiding the situation of excessive or insufficient local glue, and improving the glue coating quality. The uniform and appropriate amount of glue coating helps to enhance the bonding force between the pearlescent film and the trademark film, and improve the firmness and durability of the composite product.

[0037] A drying mechanism is installed on the frame 1, and the drying mechanism is located on the side of the glue coating mechanism away from the pearl film roller 4. The drying mechanism includes a support frame 12, and the support frame 12 is installed on the upper end surface of the frame 1.

Through the scraping effect of the scraper, the surface of the film after glue coating is smoother and the glue distribution is more even. The quality and consistency of the product can be improved. An appropriate amount of glue layer helps to evenly transfer heat during the drying process, promotes the rapid curing of glue, and improves drying efficiency and quality. Uniform and appropriate glue coating can make the bond between glue and film stronger, improve the durability of the trademark during use, and make the surface of the film after glue coating neat and smooth, without traces of glue accumulation or flow, thereby improving the appearance quality of the final product; the combination of the hot air blower 13 and the buffer box 15 can produce uniform and stable hot air, quickly and effectively dry the pearlescent film after glue coating, greatly shortening the production cycle, and the uniform drying effect helps the glue to evenly cure, avoiding the situation of local undried or over-dried, ensuring the quality and performance of the glue coating layer, and timely drying can prevent the glue from being contaminated or damaged in the uncured state, thereby improving the product qualification rate and production efficiency.

[0038] An extension frame 11 is also provided on the mounting frame 3 on which the composite film roller 10 is clamped, and a composite mechanism and a trademark film roller 21 are installed on the extension frame 11. The composite mechanism includes two symmetrically arranged composite rollers 8, and the two composite rollers 8 are both located on the extension frame 11. Transmission gears 9 are installed at both ends of each composite roller 8, and the two transmission gears 9 are meshed. A second motor 20 is installed at the end of one of the composite rollers 8 away from the transmission gear 9; the synchronous reverse rotation of the two composite rollers 8 and the meshing of the transmission gears 9 can achieve uniform pressing of the pearlescent film and the trademark film to ensure the tightness and consistency of the composite. Appropriate pressure and speed control help to fully penetrate and bond the glue between the two layers of film, further improving the strength and stability of the composite product. Precise composite operation can reduce the occurrence of defects such as bubbles and stratification, and improve the appearance quality and performance of the product.

[0039] Working principle:

[0040] First, before compounding, the composite film roller 10, the pearl film roller 4 and the trademark film roller 21 are installed. After the installation is completed, the driving motor is started to make the composite film roller 10 start to rotate, providing power for the subsequent film winding. When the pearl film released from the pearl film roller 4 passes through the tensioning wheel 6, due to the action of the torsion spring 23 between the tensioning frame 5 and the mounting frame 3 and the tensioning spring 18 between the tensioning wheel 6 and the inner wall of the movable groove 17, it can ensure that the pearl film always maintains an appropriate and stable tension. This stable tension is conducive to the smooth progress of the subsequent gluing and compounding processes, and avoids undesirable conditions such as film relaxation, wrinkles or excessive stretching. Then, the glue in the glue barrel 2 is transported to the glue cylinder 24 through the connecting pipe 22 under the action of the liquid pump. At this time, the first motor 7 drives the glue leveling frame 26 to rotate, and the central axis 2601 of the glue leveling frame 26 drives the push The glue plate 2602 rotates, and the two ends of the glue pushing plate 2602 contact the inner wall of the glue cylinder 24, so that the glue entering the glue cylinder 24 can be evenly distributed. The evenly distributed glue is then evenly coated on the lower surface of the passing pearlescent film through a number of glue coating tubes 25 evenly connected on the glue cylinder 24. The pearlescent film after glue coating continues to move forward. When passing through the scraper, the scraper scrapes off the excess glue on the pearlescent film to make the glue coating more uniform and appropriate, thereby ensuring the subsequent drying and compounding effects. Subsequently, the hot air blower 13 works to generate hot air, and the hot air is transported to the buffer box 15 through the air supply pipe 14. The buffer box 15 plays a role in buffering and evenly distributing the hot air, so that the hot air can be more evenly blown out from the air outlet pipes evenly connected to its upper end face, and the pearlescent film after glue coating is dried. This can accelerate the curing of the glue and improve production efficiency and coating quality. At the same time, the trademark film is released from the trademark film roller 21 and enters the composite mechanism together with the dried pearl film. In the composite mechanism, one of the composite rollers 8 is driven by the second motor 20 to rotate, and the two composite rollers 8 are synchronously rotated in opposite directions through the mutually meshing transmission gears 9 installed at both ends of the two composite rollers 8, so that the pearl film and the trademark film are pressed together to achieve a firm composite. Finally, the composite film passes through the tension wheel 6 to maintain tension again to ensure the flatness of the film and the tightness of the winding, and then is wound on the composite film roller 10 to complete the entire coating and composite process.
