Description

Technical Field

[0001] The present invention relates to the technical field of carton production, and specifically provides an anti-bubble film laminating packaging device and method for anti-wrinkle carton production. Background Art

[0002] Refer to the patent name: A film laminating device for packaging cartons (Publication No.: CN113071146A, Publication Date: July 6, 2021). By setting a film roll and a glue mist spraying mechanism, the spraying of the laminating glue can be well realized, ensuring the quality and effect of film lamination. At the same time, the carton clamping and positioning mechanism of the present invention can support and fix the carton from the inside of the carton, improving the support and fixing ability and applicability, ensuring the efficiency of film lamination, and realizing automatic film lamination processing; the carton clamping and positioning mechanism of this device can make the carton rotate around the horizontal axis, and the film laminated from the film roll and the glue mist spraying mechanism is wound around the carton on the carton clamping and positioning mechanism, effectively improving the accuracy, quality and efficiency of film lamination; the film roll and glue mist spraying mechanism of this device includes a film reel, an angle adjustment column, a radially extending connecting rod and a glue spraying rod, and the angle of the glue spraying rod is convenient to adjust, which can easily realize the spraying of the glue and improve the convenience of use.

[0003] Based on the above document: In the process of carton packaging production, in order to improve the aesthetics, waterproofness and wear resistance of cartons, the surface of the cartons is usually subjected to film lamination. However, in actual production, especially for anti-wrinkle cartons, due to their paper structure and surface characteristics, air bubbles are likely to appear after film lamination. These air bubbles not only affect the appearance quality of the cartons, but may also reduce the protective effect of the film lamination, resulting in problems such as film peeling off during the subsequent use of the cartons. Existing film laminating devices have obvious defects: firstly, the scraper or pressure roller structures used are simple and have fixed angles, making it difficult to fit the carton at the best angle according to the actual conditions of the carton and the film (such as the thickness, hardness or flexibility of the carton and the film) for defoaming operations, resulting in incomplete discharge of the generated air bubbles. Secondly, most devices rely only on a single scraper or pressure roller for a single defoaming, lacking a secondary defoaming process, and being unable to further eliminate the fine air bubbles remaining after the first defoaming, seriously affecting the film lamination quality and resulting in a high rejection rate of products, making it difficult to meet the requirements of the high-end packaging market. Therefore, the present invention provides an anti-bubble film laminating packaging device and method for anti-wrinkle carton production. Summary of the Invention

[0045] The defoaming assembly 43 is arranged on one side of the bearing plate 413 and is used to eliminate the bubbles on the surface of the laminated paper box.

[0046] The limiting device 2 includes symmetric limiting cylinders. A limiting rod is fixedly connected to the output end of the limiting cylinder. The limiting rod slides in a chute formed in the top of the laminating machine body 1. A limiting plate is installed at the top end of the limiting rod. The limiting plate can be used to center and limit the paper box during the conveying process;

[0047] The conveying device 3 includes a conveying motor installed at the rear of the laminating machine body 1.

The conveying wheels on both sides are connected by a conveying belt for driving. The paper box is conveyed through the conveying belt;

[0048] Both the control cylinder 412 and the lifting cylinder 414 are communicated with an external air source through air pipes.

[0049] In the embodiment of the present invention, the adjusting assembly 42 includes an electric push rod 421 installed on one side of the lifting plate 415. The output end of the electric push rod 421 is fixedly connected to an adjusting block 422. Symmetric limiting blocks 423 are installed on both sides of the adjusting block 422. The surface of the limiting block 423 slides on the inner surface of the limiting groove 418.

[0050] The electric push rod 421 is connected to an external circuit through a wire.

[0051] In the embodiment of the present invention, a heater 5 is installed on the top of the bearing plate 413. The heater 5 is fixedly connected to an electric heating wire through a high-temperature resistant wire. The electric heating wire is arranged in a mesh shape inside the scraping plate 417.

[0052] The heater 5 is connected to an external circuit through a wire;

[0053] The lifting rod 6 is used to limit the up-and-down sliding of the lifting plate 415.

[0054] By arranging a mesh electric heating wire inside the scraping plate 417, the adhesive and the film can be softened by preheating, the surface tension of the gas inside the bubbles can be reduced, and when the scraping plate 417 levels the surface of the film, large-area bubbles can be quickly discharged, realizing the flatness of the surface of the film-covered carton.

[0056] The up-and-down sliding of the bearing plate 413 can be limited by the arranged sliding grooves 7 and sliding blocks 8.

[0057] By arranging the anti-bubble mechanism 4, the inclination angle of the scraping plate 417 can be flexibly adjusted by using the adjusting component 42, and the contact angle and pressure between the scraping plate 417 and the surface of the material can be accurately controlled according to the characteristics such as the material, thickness and flexibility of the carton and the film, so that the scraping plate 417 can fit the surface of the film-covered carton in an optimal posture, enhancing the ability to squeeze and discharge bubbles.

[0058] In the embodiment of the present invention, the defoaming component 43 includes a driving motor 431 installed on the top of the bearing plate 413. One end of the output shaft of the driving motor 431 is fixedly connected with a worm 432 through a coupling. The surface of the worm 432 makes the moving plate 433 slide through a transmission component 9. One end of the moving plate 433 is slidably connected with a moving rod 434. A linkage component 10 is arranged at the top end of the moving rod 434. The bottom end of the moving rod 434 is fixedly connected with a connecting plate 435. A buffer component 11 is arranged inside the connecting plate 435. Multiple defoaming scraping blocks 436 are movably connected inside the connecting plate 435.

[0059] The driving motor 431 is a three-phase asynchronous motor and is connected to an external circuit through a wire;

[0060] The up-and-down sliding of the moving rod 434 can be limited by the moving plate 433.

[0061] In the embodiment of the present invention, the transmission component 9 includes a reciprocating lead screw 91 rotatably installed inside the bearing plate 413. A transmission block 92 is threadedly connected to the surface of the reciprocating lead screw 91. One side of the transmission block 92 is fixedly connected to the other end of the moving plate 433. A worm gear 93 is fixedly connected to the surface of the reciprocating lead screw 91. The surface of the worm gear 93 is meshed with the surface of the worm 432.

[0062] On both sides of the reciprocating lead screw 91, symmetrically arranged circulating thread grooves are provided, so that when the reciprocating lead screw 91 rotates, the transmission blocks 92 on both sides will slide synchronously towards the relative or opposite sides;

[0063] On the surface of the bearing plate 413, a sliding groove for the transmission block 92 to slide is provided, and the transmission block 92 can be slidably limited through this sliding groove.

[0064] In the embodiment of the present invention, the linkage assembly 10 includes a linkage block 101 installed at the top end of the moving rod 434. A linkage rod 102 is slidably connected inside the linkage block 101. One end of the linkage rod 102 is fixedly connected to a positioning block 103. One side of the positioning block 103 is fixedly connected to a linkage spring 104, and one end of the linkage spring 104 is fixedly connected to one side of the linkage block 101.

[0065] Under the elastic influence of the linkage spring 104, the surface of the positioning block 103 will always be in contact with the inner surface of the trapezoidal positioning groove 13.

[0066] In the embodiment of the present invention, a positioning plate 12 is fixedly connected to one side of the bearing plate 413. A trapezoidal positioning groove 13 is provided on the surface of the positioning plate 12, and the inner surface of the trapezoidal positioning groove 13 is slidably connected to the surface of the positioning block 103.

[0067] The trapezoidal positioning groove 13 is a segmented sliding groove, which can be regarded as four segments, namely: the lower segment, the right segment, the upper segment, and the left segment, and all are inclined sliding grooves. The intersection of adjacent two segments of the sliding grooves is designed with a height difference. Taking the intersection of the lower segment and the right segment as an example, the lower segment sliding groove here is slightly higher than the right segment sliding groove. Combining with the attached Figure 9 As can be seen, when the positioning block 103 slides on the inner surface of the trapezoidal positioning groove 13, at this time, the positioning block 103 is located in the lower segment of the trapezoidal positioning groove 13 and based on the attached Figure 9 As a reference plane, it can be seen that the positioning block 103 slides from left to right on the inner surface of the trapezoidal positioning groove 13. When the positioning block 103 slides to the rightmost side, at this time, the positioning block 103 is located at the intersection of the lower segment sliding groove and the right segment sliding groove. Since the lower segment sliding groove here is slightly higher than the right segment sliding groove, it will cause the surface of the positioning block 103 to always fit in the right segment sliding groove under the elastic influence of the linkage spring 104 after the positioning block 103 slides to the intersection. And at this time, when the reciprocating lead screw 91 pulls the transmission block 92, the moving plate 433, the moving rod 434, the linkage block 101, the linkage rod 102 and the positioning block 103 to start resetting, the positioning block 103 slides in the right segment sliding groove under the limit of the height difference and continues to slide into the upper segment sliding groove, so as to realize the cyclic sliding operation of the positioning block 103.

[0068] In the embodiment of the present invention, the buffer assembly 11 includes a connecting rod 111 installed on the inner wall of the connecting plate 435 and a buffer spring 112. The surface of the connecting rod 111 is rotatably connected to the inside of the defoaming scraper 436, and one end of the buffer spring 112 is fixedly connected to the surface of the defoaming scraper 436.

[0069] By providing the defoaming assembly 43, driven by the driving motor 431, multiple groups of defoaming scrapers 436 on both sides can reciprocate synchronously. Through the secondary defoaming operation, the remaining fine bubbles can be completely squeezed out. And by providing the buffer assembly 11, it can adaptively deform according to the resistance during scraping, evenly dispersing the resistance of the defoaming scraper 436 during scraping, and avoiding damage to the film due to excessive resistance.

[0070] A control terminal is installed on one side of the film laminating machine body 1. Through the control terminal, electrical components such as the control cylinder 412, lifting cylinder 414, electric push rod 421, driving motor 431, and heater 5 can be flexibly adjusted.

[0071] The present invention also discloses a method for a foam-proof film laminating packaging device based on the production of anti-wrinkle cartons, which specifically includes the following steps:

[0072] S1. Film lamination and conveying: First, place the carton on the top of the film laminating machine body 1, use the limiting device 2 to center and limit both sides of the carton, and use the conveying device 3 to convey the carton. After the anti-wrinkle carton is laminated by the laminating roller, it will continue to be conveyed by the conveying device 3 to the lower part of the support plate 411;

[0073] S2. Foam-proof operation: Use the scraper 417 in the foam-proof assembly 41 to scrape the surface of the anti-wrinkle carton after film lamination, so that the film can fully adhere to the surface of the anti-wrinkle carton;

[0074] S3. Adjustment operation: Adjust the inclination angle of the scraper 417 through the adjustment assembly 42, so that the scraper 417 can be used for scraping flat operations on films and cartons with different thicknesses, hardnesses, and flexibilities;

[0075] S4. Defoaming operation: Laterally scrape the surface of the carton after film lamination through the defoaming assembly 43. Through multiple reciprocating scrapings, the bubbles generated on the surface of the anti-wrinkle carton after film lamination can be efficiently and thoroughly eliminated.

[0076] At the same time, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0077] During operation, first place the paper box on the top of the laminating machine body 1. Use the limiting device 2 to center and limit both sides of the paper box, and use the conveying device 3 to convey the paper box. After the paper box is laminated by the laminating roller, it will continue to be conveyed by the conveying device 3. During this process, start the control cylinder 412 to drive the entire bearing plate 413 to slide downward. The sliding of the bearing plate 413 will cause the defoaming scraping block 436 and the scraping plate 417 to slide downward synchronously. At this time, the surface of the laminated paper box can be scraped by the scraping plate 417. Use the scraping plate 417 to scrape the surface of the laminated paper box during transportation to prevent the generation of bubbles. During the scraping process, start the heater 5 to heat the electric heating wire inside the scraping plate 417 through the high-temperature wire, so that the temperature at the lower end of the scraping plate 417 rises to 30 - 70 °C. The specific temperature can be adjusted according to the paper box and laminating material with different thicknesses. Using the heated scraping plate 417 can significantly improve the laminating quality. By temperature control, the physical properties of bubbles, glue, and laminating materials can be changed, promoting gas discharge and enhancing the interface bonding effect. And start the electric push rod 421 to drive the adjusting block 422 and the limiting block 423 to slide, so that the limiting block 423 slides on the inner surface of the limiting groove 418. As the limiting block 423 slides, the inclination angles of the adjusting plate 416 and the scraping plate 417 will change. By adjusting the inclination angle of the scraping plate 417, it is convenient to flexibly adjust for laminations with different thicknesses, hardnesses, and flexibilities, avoiding damage to the lamination while efficiently eliminating bubbles. Synchronously, when the angle of the scraping plate 417 changes, start the lifting cylinder 414 to drive the entire lifting plate 415 to slide downward, so that the lifting rod 6 slides inside the bearing plate 413, thereby realizing fine adjustment of the height of the scraping plate 417. After the laminated paper box is scraped flat by the scraping plate 417, it will continue to be conveyed below multiple groups of defoaming scraping blocks 436. At this time, start the driving motor 431 to drive the worm 432 to rotate. The rotation of the worm 432 will drive the worm gear 93 and the reciprocating lead screw 91 to rotate. The rotation of the reciprocating lead screw 91 will cause the two transmission blocks 92 to slide in the sliding grooves opened on the surface of the bearing plate 413. The sliding of the transmission blocks 92 will drive the moving plate 433, the moving rod 434, the connecting plate 435, the linkage assembly 10, the buffer assembly 11, and the defoaming scraping block 436 to slide reciprocally synchronously. During the reciprocating sliding of the defoaming scraping block 436, the positioning block 103 in the linkage assembly 10 will slide on the inner surface of the trapezoidal positioning groove 13. The trapezoidal positioning groove 13 is designed with segmented high and low levels, which will cause the positioning block 103 to slide cyclically on the inner surface of the trapezoidal positioning groove 13. When the positioning block 103 slides to the lower section of the trapezoidal positioning groove 13, at this time, the bottoms of multiple groups of defoaming scraping blocks 436 are in contact with the top of the laminated paper box, and multiple groups of defoaming scraping blocks 436 on both sides scrape from the middle to both sides. The reciprocating scraping of multiple groups of defoaming scraping blocks 436 can eliminate the fine bubbles on the surface of the laminated paper box. When the positioning block 103 slides to the upper section of the trapezoidal positioning groove 13,Driven by the positioning block 103, the linkage block 101, the linkage rod 102, the linkage spring 104 and the moving rod 434 will slide upward synchronously, causing the moving rod 434 to slide inside the moving plate 433. The moving rod 434 drives the connecting plate 435 and the defoaming scraper block 436 to slide upward synchronously, separating the bottoms of multiple groups of defoaming scraper blocks 436 on both sides from the top of the film-coated paper box and starting to reset. This can prevent the defoaming scraper block 436 from scraping the bubbles that were not removed in the first pass back to the middle of the film-coated paper box during the reset process. Synchronously, when the defoaming scraper block 436 slides towards both sides, if it encounters small bubbles that are difficult to remove, the defoaming scraper block 436 will rotate on the surface of the connecting rod 111 under the influence of resistance, compressing the buffer spring 112. The buffer spring 112 is used to buffer this resistance, preventing the defoaming scraper block 436 from scratching the film or bursting the bubbles due to excessive resistance. Through multiple reciprocating scrapings of multiple groups of defoaming scraper blocks 436 on both sides, the bubbles generated on the surface of the anti-wrinkle paper box after film coating can be efficiently and thoroughly eliminated, greatly improving the finished product quality of the anti-wrinkle paper box.
