Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically to an auxiliary coating equipment for the production of aluminized paper. Background Technology

[0002] Metallized paper is mainly composed of base paper, aluminum layer and coating. It has good gloss and smoothness, good flexibility, high aluminum coating fastness, beautiful appearance and environmental protection. At the same time, it has good printing performance and machinability. Therefore, it can be widely used for exquisite packaging of products such as cigarettes, wine, bottle labels, tea, food, cosmetics, daily chemicals, department stores, gifts, and handicrafts.

[0003] Metallized paper production is gradually replacing traditional non-environmentally friendly packaging materials such as aluminum foil with vacuum metallized paper. There are two main methods for producing vacuum metallized paper: direct metallization and transfer metallization. Direct metallization requires high-quality paper and strict process control, and its use is decreasing. Transfer metallization, on the other hand, involves first metallizing a roll of polyester or polypropylene film, then transferring the aluminum film to a paper base using an adhesive, and finally peeling off the plastic film. This process has lower requirements for the paper quality. Vacuum metallization using the transfer method includes batching, coating, molding, metallization, lamination, peeling, and paper cutting. In addition to packaging and other processes, during the lamination process, the aluminum film enters from the top and contacts the paper at the bottom. When the paper surface is damp or dirty (because it is inconvenient to observe inside the paper tube during winding, the paper surface at the inner winding part of the paper tube is prone to dampness or dirt), the aluminum film and the paper surface come into contact. After the glue is filled, the damp paper surface can easily lead to poor lamination strength, and the dirty paper surface can easily cause the glue to be squeezed out from the dirty area to the outer edge of the lamination surface, resulting in irregular white spots at the lamination position. To address this, we have proposed an auxiliary coating equipment for the production of aluminized paper. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary coating equipment for the production of aluminized paper, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary coating equipment for metallized paper production, comprising a set of mutually symmetrical frame plates, with support columns connected to the bottom of the frame plates, an aluminum film guide roller connecting the two frame plates to guide the aluminum film, and a paper base guide roller at the bottom of the aluminum film guide roller, the two ends of the paper base guide roller being connected to the frame plates on both sides; a pre-pressing assembly for pre-pressing the aluminum film and paper surface is provided between the two frame plates, and a cleaning assembly for drying and cleaning the paper surface entering the pre-pressing assembly is provided between the pre-pressing assembly and the paper base guide roller; an adhesive coating assembly is provided on one side of the pre-pressing assembly, the adhesive coating assembly being distributed between the pre-pressed aluminum film and the paper surface, and the two sides of the adhesive coating assembly being connected to the inner sides of the two frame plates respectively, and a scraper for scraping adhesive at the composite position of the aluminum film and paper surface is connected to one side of the adhesive coating assembly, for pre-treatment before the aluminum film and paper surface are composited.

[0006] Preferably, the pre-pressing assembly includes pressure rollers disposed inside two frame plates, with the two pressure rollers distributed vertically. The frame plates are provided with adjustment grooves, and the two ends of the pressure rollers are connected to adjustment shafts that pass through the adjustment grooves. One end of the adjustment shaft that passes through the adjustment groove is connected to an adjustment nut. An adjustment screw is connected to the same side of the two adjustment shafts, and a fixing nut is connected to the contact point between the adjustment screw and the adjustment shaft. Adjusting the position of the pressure rollers will initially press the paper and aluminum film together.

[0007] Preferably, the cleaning assembly includes an air pump connected to the outside of one of the frame plates. The output pipe of the air pump passes through the frame plate and is connected to a processing horizontal pipe. The air pump introduces drying hot air into the processing horizontal pipe. The end of the processing horizontal pipe away from the output pipe is connected to a mounting shaft, which is connected to another frame plate. The processing horizontal pipe has multiple drying ports and multiple cleaning rods connected to it. One end of each cleaning rod is located inside the processing horizontal pipe. Multiple gas-driven components corresponding to the cleaning rods are connected inside the processing horizontal pipe. Under the action of the hot air introduced into the processing horizontal pipe, the gas-driven components push the cleaning rods to clean the paper surface. The hot air helps to dry the paper surface while simultaneously pushing the cleaning rods to clean the paper surface.

[0008] Preferably, the gas propulsion component includes a gas collecting shell connected inside the processing horizontal tube. A vent is provided on one side of the gas collecting shell, and an inlet cylinder is connected to the other side. The diameter of the inlet cylinder at the outer end of the gas collecting shell is smaller than that at the inner end, and multiple vent holes are provided at the inner end of the inlet cylinder. A piston plate is connected inside the inlet cylinder, and a return spring is connected between the piston plate and the inner wall of the inlet cylinder. A swing fan blade is connected to the end of the cleaning rod located inside the gas collecting shell, and the swing fan blade is located on one side of the inlet cylinder. A return spring is connected between the swing fan blade and the inner wall of the gas collecting shell, facilitating the return of the swing fan blade.

[0009] Preferably, a negative pressure pump is connected to the outside of one of the frame plates, and the negative pressure pump is located on the side away from the air pump. The frame plate on which the negative pressure pump is installed is provided with an adsorption port, and an adsorption pipe is connected to the adsorption port. The adsorption pipe is connected to the negative pressure pump, and the dirt after cleaning is adsorbed by the negative pressure.

[0010] Preferably, the adhesive application assembly includes an adhesive application tube disposed between two frame plates, and the adhesive application tube is located behind the aluminum film guide roller and the paper base guide roller. One end of the adhesive application tube is connected to an adhesive pump body passing through the frame plate, and the other end of the adhesive application tube is connected to a rotating rod. One end of the rotating rod passing through the frame plate is connected to a first bevel gear. A second bevel gear meshes with the outer side of the first bevel gear. The second bevel gear is connected to a drive motor, and the drive motor is connected to the outer side of the frame plate. Multiple adhesive application points are distributed at equal angles on the outer side of the adhesive application tube, and a uniform adhesive is connected between each adjacent adhesive application point layer. The design of the uniform adhesive serves to isolate the adhesive application position and facilitates the uniform application of adhesive at the application position.

[0011] Preferably, the adhesive scraper includes a fixed rod disposed on one side of the adhesive applicator tube. Fixed plates are connected to both ends of the fixed rod, and adhesive scraping sponge blocks are connected to the upper and lower sides of the fixed plates. The two adhesive scraping sponge blocks are distributed on the outer sides of the aluminum film and the paper base. One fixed plate is connected to a limiting slider, and a limiting groove is provided on the corresponding frame plate. The limiting slider is slidably connected to the limiting groove. The other fixed plate is connected to a pushing rod, and a pushing groove is provided on the corresponding frame plate. The pushing rod is slidably connected to the pushing groove. One end of the pushing rod is connected to a pushing cylinder, which is connected to the outer side of the frame plate. The cooperation of the limiting groove and the limiting slider facilitates the stable sliding of the two fixed plates.

[0012] Preferably, the cleaning rod has an inverted transition arc at the contact point with the paper surface, which helps to clean the paper surface thoroughly.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the paper base and aluminum film are pre-treated before lamination. The paper base surface is dried by hot air in the cleaning component, which also cleans the paper surface. This avoids problems such as dampness or dirt on the paper surface when laminating the paper and aluminum film, and reduces the impact of the paper surface on the adhesive during the coating process. At the same time, the adhesive scraper removes the excess adhesive after the adhesive is applied by the adhesive coating component, which prevents irregular white spots from appearing during resetting due to adhesive overflow or lack during the lamination process.

[0014] 2. The present invention, by designing two mutually symmetrically distributed pressure rollers, facilitates the preliminary pressing treatment of aluminum film and paper base surface before lamination, thus avoiding edge curling during the lamination process. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-11 This invention provides a technical solution: an auxiliary coating equipment for metallized paper production. This solution solves the problems of damp and dirty paper surfaces, poor adhesive adhesion, and composite white spots that occur during existing transfer metallization methods. The design of this solution includes a set of symmetrical frame plates 1, with support columns 11 connected to the bottom of each frame plate 1. An aluminum film guide roller 2 is connected between the two frame plates 1 to guide the aluminum film. A paper base guide roller 3 is located at the bottom of the aluminum film guide roller 2. The pre-coated aluminum film enters from the aluminum film guide roller 2, while the paper base roll begins to roll from the bottom of the paper base. The guide roller 3 enters upwards, and both ends of the paper-based guide roller 3 are connected to the two side frame plates 1; a pre-pressing assembly 4 is provided between the two frame plates 1 for pre-pressing aluminum film and paper surface, and a cleaning assembly 5 is provided between the pre-pressing assembly 4 and the paper-based guide roller 3 for drying and cleaning the paper surface entering the pre-pressing assembly 4; a glue coating assembly 6 is provided on one side of the pre-pressing assembly 4, the glue coating assembly 6 is distributed between the pre-pressed aluminum film and the paper surface, and both sides of the glue coating assembly 6 are connected to the inner side of the two frame plates 1 respectively, and a scraper 7 for scraping glue at the composite position of the aluminum film and the paper surface is connected to one side of the glue coating assembly 6.

[0019] The aluminum film guide roller 2 and the paper base guide roller 3 guide the aluminum film and paper base into the positions of the two symmetrically designed frame plates 1. According to the thickness requirements between the paper base and the aluminum film, the pre-pressing component 4 is adjusted to perform preliminary pre-pressing on the aluminum film and paper base to avoid edge curling during the lamination process. At the same time, before entering, the paper base surface is dried with hot air by the cleaning component 5, and the paper surface is cleaned under the action of hot air to remove dirt. After the paper surface and aluminum film are initially pressed and oriented, the glue application component 6 applies glue. The glue scraper 7 scrapes along the reset edge to scrape off the excess glue, preventing the excess glue from accumulating at the lamination edge, thereby effectively reducing problems such as weak glue adhesion and irregular white spots during reset.

[0020] Reference Appendix Figure 3The pre-compression assembly 4 shown includes pressure rollers 41 disposed inside two frame plates 1, with the two pressure rollers 41 arranged vertically. The frame plates 1 are provided with adjustment grooves 42. Adjustment shafts 43 passing through the adjustment grooves 42 are connected to both ends of the pressure rollers 41. One end of the adjustment shaft 43 passing through the adjustment groove 42 is connected to an adjustment nut 44. Adjustment screws 45 are connected to the same side of the two adjustment shafts 43, and a fixing nut 46 is connected to the contact point between the adjustment screws 45 and the adjustment shafts 43. The aluminum foil enters from the upper aluminum foil guide roller 2, while the paper in the paper base roll is guided in from the lower paper base guide roller 3. Adjustments are made according to the thickness between the paper base surface and the aluminum foil surface, as well as the adhesive application requirements. First, the pressure rollers 41 distributed at the upper end... Loosen the outer fixing nut 46 and simultaneously loosen the outer fixing nut 46 of the lower pressure roller 41, so that the upper and lower pressure rollers 41 are adjusted along the position of the adjusting screw 45 until the gap between the upper and lower pressure rollers 41 meets the spacing requirements between the aluminum film and the paper base surface (adjusted within a range of 5-10mm larger than the required gap). After the gap is adjusted, re-fix the upper and lower fixing nuts 46, and fix the adjusting nut 44 on the adjusting shaft 43 to the position of the groove wall of the adjusting groove 42. At this time, the guided aluminum film passes through the upper gap position and the paper base surface passes through the lower gap position. The aluminum film and the paper base surface are initially pressed together by the upper and lower pressure rollers 41 to avoid curling.

[0021] Reference Appendix Figure 4-9The paper base surface is pre-treated as shown in the diagram. The cleaning assembly 5 includes an air pump 51 connected to the outside of one of the frame plates 1. The air pump 51 communicates with hot air to exhaust it. The output pipe of the air pump 51 passes through the frame plate 1 and is connected to a processing horizontal pipe 52. The air pump 51 introduces drying hot air into the processing horizontal pipe 52. The end of the processing horizontal pipe 52 away from the output pipe is connected to a mounting shaft 53, which is connected to another frame plate 1. The processing horizontal pipe 52 is provided with multiple drying ports 54. Multiple cleaning rods 55 are connected to the upper part of the paper surface. Each cleaning rod 55 has an inverted transition arc at its contact point with the paper surface. One end of each cleaning rod 55 is located inside the processing horizontal tube 52. Multiple gas-driven components 8, corresponding to the cleaning rods 55, are connected inside the processing horizontal tube 52. Under the action of hot air introduced into the processing horizontal tube 52, the gas-driven components 8 push the cleaning rods 55 to clean the paper surface. A negative pressure pump 56 is connected to the outer side of one of the frame plates 1, and the negative pressure pump 56 is located on the side away from the air pump 51. The frame plate 1 on which the negative pressure pump 56 is installed has an adsorption port 57. A suction pipe 58 is connected to a negative pressure pump 56. An air pump 51 introduces hot air from the output pipe into the processing horizontal pipe 52. Because multiple inclined drying ports 54 are opened on the processing horizontal pipe 52, the introduced hot air is blown from the drying ports 54 onto the paper surface, thereby drying the paper. During the introduction of hot air, the hot air passes through the gas pushing component 8, causing the cleaning rod 55 connected to the gas pushing component 8 to swing and clean the paper surface, facilitating the removal of dirt from the paper. In this design, the cleaning rod 55 is made of soft rubber, and the bottom... The inverted transition arc segment, designed to fit snugly against the paper surface, swings under the action of the gas pusher 8, causing the transition arc segment to detach the dirt from the paper surface. During the detachment process, the negative pressure pump 56 on the other side generates negative pressure gas, thereby creating an attraction force at the adsorption port 57, adsorbing the loosened dirt from the paper surface. In this design, the cleaning rod 55 is designed at the front end of the drying port 54, realizing the cleaning of dirt at the front end and the drying of the cleaned paper surface at the rear end, making it easy to push the clean paper surface into the reset position for lamination.

[0022] Reference Appendix Figure 7-8The specific mechanism of the gas propulsion component 8 shown is as follows: The gas propulsion component 8 includes a gas collecting shell 81 connected inside the processing horizontal tube 52. One side of the gas collecting shell 81 has a vent 82, and the other side is connected to an inlet cylinder 83. The diameter of the inlet cylinder 83 at the outer end of the gas collecting shell 81 is smaller than that at the inner end, and the inner end of the inlet cylinder 83 has multiple vent holes 84. A piston plate 85 is connected inside the inlet cylinder 83, and a return spring 86 is connected between the piston plate 85 and the inner wall of the inlet cylinder 83. A swinging fan blade 87 is connected to the end of the cleaning rod 55 located inside the gas collecting shell 81, and the swinging fan blade 87 is located on one side of the inlet cylinder 83. A return spring 88 is connected between the swinging fan blade 87 and the inner wall of the gas collecting shell 81. When the air pump 51 introduces hot air into the processing horizontal tube 52, the hot air is introduced through the multiple gas collecting shells 81 installed inside the processing horizontal tube 52 from the small diameter inlet. One end of the cylinder 83 enters, pushing the piston plate 85 to compress the return spring 86. When the piston plate 85 is pushed to multiple vent holes 84, hot air is dispersed from the vent holes 84 into the air collecting shell 81, causing the swinging fan blade 87 to swing. Because the swinging fan blade 87 is fixedly connected to one end of the cleaning rod 55, the cleaning rod 55 swings and cleans the paper surface when the swinging fan blade 87 swings. At the same time, hot air is discharged from the vent 82 at the other end. In this scheme, the inlet diameter of the cylinder is smaller than the outlet diameter of the cylinder inside the cylinder 83, so the amount of air entering is less than the amount of air being discharged. This causes the return spring 86 to push the piston plate 85 back to its original position, and the return spring 88 resets the swinging fan blade 87, thus realizing the intermittent swinging of the cleaning rod 55. The intermittent swinging design here takes into account the inverted transition arc section at the bottom of the cleaning rod 55. The intermittent swinging facilitates a large swinging amplitude of the transition arc section, which is beneficial for cleaning the dirt on the paper surface.

[0023] Reference Appendix Figure 10The adhesive application process shown in the diagram includes an adhesive application tube 61 positioned between two frame plates 1, located behind the aluminum film guide roller 2 and the paper base guide roller 3. One end of the adhesive application tube 61 is connected to an adhesive pump body 62 passing through the frame plate 1, and the other end is connected to a rotating rod 63. A first bevel gear 64 is connected to one end of the rotating rod 63 passing through the frame plate 1. A second bevel gear 65 meshes with the outer side of the first bevel gear 64. The second bevel gear 65 is connected to a drive motor 66, which is connected to the outer side of the frame plate 1. Multiple adhesive application dots 67 are distributed at equal angles on the outer side of the adhesive application tube 61. Furthermore, each adjacent glue application point layer 67 is connected by a uniformly coated adhesive 68. After the paper surface is cleaned, the paper surface and aluminum film are initially pressed together by the pressure roller 41. The aluminum film and paper surface are kept in a relatively parallel position and enter the lamination position. The existing reset equipment is used to perform the lamination process. Before lamination, the glue pump body 62 pours glue from the glue application tube 61 and applies glue to the paper surface and aluminum film surface along the multiple glue application point layers 67. At the same time, the drive motor 66 drives the first bevel gear 64 to move by driving the second bevel gear 65, thereby making the entire glue application tube 61 rotate to apply glue. After the glue is applied, the adjacent uniformly coated adhesive 68 can easily spread the glue evenly on the surface.

[0024] To prevent the adhesive from overflowing onto the edges of the paper and aluminum foil surfaces, it needs to be scraped off. The scraper 7 includes a fixed rod 71 on one side of the adhesive applicator 61. Fixed plates 72 are connected to both ends of the fixed rod 71, and scraper sponge blocks 73 are connected to the upper and lower sides of the fixed plates 72. The two scraper sponge blocks 73 are distributed on the outer sides of the aluminum foil and paper base. One of the fixed plates 72 is connected to a limiting slider 74, and a limiting groove 75 is provided at the corresponding frame plate 1. The limiting slider 74 is slidably connected to the limiting groove 75. The other fixed plate 72 is connected to a push rod 76, which is relatively... A push groove 77 is provided at the corresponding frame plate 1. The push rod 76 is slidably connected to the push groove 77. One end of the push rod 76 is connected to a push cylinder 78, which is connected to the outside of the frame plate 1. The push cylinder 78 pushes one of the fixed plates 72 to move along the push groove 77. At the same time, the other fixed plate 72 is fixed to one side of the moving fixed plate 72 by a fixed rod 71, so that both fixed plates 72 move along the push groove 77 at the same time. In this solution, the fixed plates 72 are designed with a sloping arc-shaped scraping sponge block 73 at the upper and lower ends. After the glue is scraped off at one end of the scraping sponge block 73, it slides down the rising slope to the bottom, reducing the accumulation of glue at the scraping sponge block 73.
